Matters needing attention during printing press operation

Pay attention to details when booting

1. Set equipment parameters

2. Take the printing plate

1) Check whether the version number is correct

2) Check whether the center line is complete

3) Check whether the plate paper and the plate are complete

4) Check whether the layout is abnormal, for example, the printing plate is not firmly adhered

5) Check whether the bridge is installed

6) Check whether the layout is damaged, warped, dry ink, dirty, etc. If you refuse to accept it, the responsibility belongs to the staff of the layout room

At the same time, it should also be noted that if an abnormality is found when the version is taken, the template personnel must immediately handle it, and then take it to the machine and report it to the captain. The captain needs to truthfully report the problem and the delay in the report, and report it. Prepare foreman, foreman must truthfully reflect on the report.

3. Take the ink

1) Check whether the number is correct

2) Check and record the weight

3) Check whether the viscosity is within the control range (20±5 seconds) and record

4) Take the variegated ink color card together

5) Register the order number

6) Get the ink according to the order

4. Upper printing plate

1) According to the order requirements and the captain's plan to print

2) The center line of the printing plate is aligned with the center line of the roller (both up and down must be aligned)

3) When loading the printing plate, hold the printing plate with your hand to prevent it from falling

4) The lock should be tightened

5) The larger printing plate should be reinforced with transparent adhesive (do not use double-sided adhesive)

6) After loading the printing plate, the wrench cannot be placed in the machine

7) The rotary switch needs to be used when the roller is stationary

8) Make sure that the direction of the bite is the same as the leading edge of the cardboard when entering the plate on the flat rolling order.

5. Put the cardboard

1) Manually position the rear baffle according to the width of the cardboard (you must first loosen the lock, adjust the position, and then lock the lock)

2) The position of the cardboard and the rear baffle should not be too tight

3) The position of the guide frame on both sides and the two sides of the cardboard should not be too tight

4) The cardboard should be placed flat on the feeding table

5) Consider the width of the cardboard (if it is too small, increase the width)

6) Suction plates should be added to the blast holes on both sides of the cardboard

7) Don't put too much cardboard (about 10 sheets)

6. Tuning

1) The start button only needs to be pressed once, and then press it again after 3 seconds to start (no need to press continuously)

2) Set the vehicle speed to a low speed (about 80 yards)

3) Click the FEED ONE artwork on the console, input a page of cardboard, and press the STOP button to stop after the cardboard passes through the machine properly

4) To stop, press the normal stop button (STOP button), do not press the emergency stop button

5) The machine cannot be started if the gap parameters are not set in place

6) Do not adjust the position of the grooving knife during the operation of the machine to prevent the upper knife and the lower knife from colliding

7) The die-cutting gap of round die (scattered die) orders should be set at zero, and it will be deepened after adjustment.

8) Slotting orders that have pressure resistance requirements must be strengthened in advance

7. Set up the stacker

A. Set up the stacker

1) The two side rails should be symmetrical with the cardboard size to avoid uneven stacking

2) The position of the delivery tray should be set according to the width of the cardboard

3) Set the stack height

4) To set the paper tray, loosen the lock first, adjust it, and then lock it again.

B. Set the small stacker

1) Adjust the paper beater according to the cardboard size

2) The gap between the paper beater and the cardboard should not be too tight

3) Set the scale door and scraping height according to the cardboard flute

4) Adjust the paper feeding positioning optical eye according to the length of the cardboard

8. First article inspection

1) The captain calls out the first picture, and the forehand needs to check the artwork and color hue. If these two items are abnormal, the forehand bears the corresponding responsibility, and the captain is responsible for other items

2) The first inspection form must be filled in completely and signed by the captain for confirmation

3) Only after the first inspection of quality control is completed and signed for confirmation, can production

4) Check item by item according to the requirements of the first article checklist and fill in the checklist

5) The first product needs to be signed by the captain and quality control to put it on the first shelf

6) Molding inspection must be done, and immediately report to any doubts

7) For any order that does not conform to the version, the production must be stopped immediately and reported to the upward

9. Push the cardboard

1) Need to check the size, crimping, paper color, flatness, flute type, materials, etc.

2) Confirm the flatness, the bent cardboard shall be opened to the end, and the bending direction shall be consistent. Exceeding the range (width 1m, bending and arching 2mm), require pre-folding before going on the machine

3) Paper scraps on both sides of the cardboard must be removed in advance

4) Check whether the leading edge of the cardboard is aligned with the leading edge of the multilayer board

5) For flat rolling and round rolling orders, pay special attention to whether the cardboard is uneven. If so, it is required to pick out and put it at the end, and the uneven side needs to be placed behind. The unevenness of the manual rolling order cannot exceed 10mm, and it will be automatically flattened. The rolling order cannot exceed 7mm (Note: When the cardboard size is the same as the order requirement, the above processing is performed, if the actual cardboard size is larger than the order requirement, it will be processed separately)

6) Pay attention that the cardboard can't be stacked too high (can't exceed the height of the paper feeder)

7) Pay attention to the cardboard, the board and the board can not be connected together

1 0. Prepare multi-layer boards

1) Pick out the bad ones, sort them out, and deal with them uniformly after get off work

2) The pushed multi-layer boards should be neatly placed in the specified area

3) Handle with care, do not throw or throw, to prevent damage

11. Wipe the plate

1) Wipe with a clean cloth

2) Do not scrub with xylene

3) Do not wipe vigorously, especially small print and dots

4) After wiping the revised part, check whether the printing plate is stuck

5) Do not use too much water to prevent the printing plate from getting wet and degumming the sticking area of the printing plate

6) After the dots are wiped, use the air pipe to blow dry, but the distance between the air pipe and the printing plate should not be too close to prevent the air pressure from blowing the dots

12. Sampling

1) Sampling every 100 sheets

2) Sampling inspection items are the same as the first inspection items

3) For larger orders, pay attention to the color change, and leave one sheet for the color comparison of the starting product and the subsequent product (check once every 500 sheets or so)

4) Sampling inspection must be done to check the molding, and press the line as deep as possible (press until it is not broken, which is convenient for processing and production)

5) The random inspection products are placed in the same direction, and flat rolling orders should also be marked

6) Stop and start again, the first five sheets need to be selected for full inspection

7) Special attention should be paid to the co-version of the layout, the layout is easy to fall off during the production process

13. Indication sheet

1) The order number, product name (customer name), manufacturing date, shift type, machine type and number of boards must be filled in correctly

2) Each board needs to be marked

3) It needs to be clamped in the middle section of the cardboard to prevent it from falling

14. Flat rolling label

1) Need to go from the first to the last

2) Keep the same direction before and after

3) Be careful not to bite the injector on the face paper or bottom paper

15. Processing of the tongue piece

1) Deal with it in a timely manner

2) Dispose of the tabs should be put in the waste paper box uniformly, do not throw on the ground

3) Pour into the baler slowly and appropriately to prevent the conveyor belt from jamming

4) When each pallet is sent to the subsequent processing area, it is necessary to ensure that the chip removal is clean and complete

16. Paper feeding

1) The bent cardboard should be picked out in time for unified treatment, and left until the final production (out of scope)

2) In the production process, if there is a flat or bent cardboard in the front and rear (the bending and warping are within the control range), the captain must be notified in time to adjust the speed

3) When encountering a paper jam, cut off the paper feed power supply first, and then turn off the suction sheet and paper feed button before processing

4) The paper feeder must not sit on the feeding table or the raising arm

5) Do not operate with gloves

6) When disposing of waste materials and multilayer boards, be careful not to collide with the lifting arm

7) Manual lifting, pay attention to whether there are people on the side

17, stacking

1) Stack must be neat

2) The stack height and quality are consistent

3) Multi-layer boards should be handled gently when changing boards

4) The multi-layer board needs to be laid with waste cardboard to prevent the product from being contaminated (the same order cannot be used to adjust the product to prevent the processing from being mixed into the finished product)

5) The defective products only need to be covered with multi-layer boards, not too much, and scraps of waste paper cannot be used
