Description

TECHNICAL FIELD

[0002] With the development of society, the functional requirements of release paper in packaging, electronics, pharmaceutical and other industries are constantly upgrading. Air guide groove release paper, as a kind of release paper with special structure, can quickly discharge interlayer air during lamination and effectively avoid air bubbles, and is widely used in sticker lamination, protective film lamination, die cutting and other scenes.

[0003] The production of air guide groove release paper needs to go through key processes such as "paper substrate pretreatment-polyethylene coating-pressing air guide groove-coating liquid silicone". Among them, the paper coating link is the core step to determine the forming effect of air guide groove and the release performance. The existing paper coating device first coats a polyethylene coating on the surface of the release paper substrate, then presses the air guide groove through a groove pressing roller, and finally coats liquid silicone to form a release layer. However, during the coating of liquid silicone, due to the fluidity of liquid silicone and the flat spraying or roller coating method used by the existing coating device, the silicone is easy to flow into and fill the already pressed air guide groove, causing the air guide groove to be blocked or the depth to be shallower. This problem will trigger a series of chain reactions: first, the air guide groove loses its air discharge function, and air bubbles cannot be discharged during downstream lamination, resulting in a significant decrease in product pass rate; second, manual cleaning of the blocked air guide groove is required, increasing labor costs and production cycle; third, the cleaning process is easy to scratch the release layer, damaging the release performance of the release paper and further reducing product quality; fourth, for high-precision air guide grooves, the existing coating method almost cannot avoid blockage, resulting in the need for imported high-end air guide groove release paper, increasing the production cost of enterprises.

[0025] Working principle: before use, install the release paper substrate to be processed on the paper roll 2, pass the free end of the release paper body 5 between the two groups of clamping roller groups 4 and between the supporting roller 1201 and the pressing groove roller 1202 in sequence, and finally wind and fix on the paper roll 3, inject sufficient polyethylene raw materials into the storage box one 7, inject sufficient liquid organic silicon raw materials into the storage box two 8, rotate the rotating knob 22 to drive the screw rod 20 to rotate, the screw rod 20 is threadedly connected with the screw hole 21, drives the connecting frame 19 and the mounting plate 6 to ascend and descend along the supporting rod 15, and at the same time, the spring 18 is compressed, until the arc-shaped scraper 11 is close to the surface of the release paper body 5, the pressing groove roller 1202 and the supporting roller 1201 form a moderate pressure on the release paper body 5, so as to ensure the coating and pressing groove effect, and then the rotating knob 22 is closed after the adjustment is completed.

[0026] Start the equipment, the paper roll 3 is uniformly rotated under the driving of an external power source, the release paper body 5 is driven out of the paper roll 2 by friction, conveyed along the preset path, and the two groups of clamping roller groups 4 clamp and tension the release paper body 5 to avoid wrinkles or deviation during conveying.

[0027] At the same time, the driving motor 1401 of the driving assembly 14 is started, and the driving motor 1401 outputs power to drive the rotating shaft 903 at the bottom of the storage box 7 to rotate. On the one hand, the rotating shaft 903 drives the rear paddle 902 in the output pump 9 to rotate, and the rear paddle 902 drives the front paddle 902 to rotate in the opposite direction through gear engagement. The two paddles 902 extrude the polyethylene raw material in the storage box 7, and the polyethylene raw material is pressurized and then transported to the distribution box 1001 through the discharge pipe of the sealing cover 901. The distribution box 1001 uniformly distributes the polyethylene to a plurality of nozzles 1002, and the nozzles 1002 spray the polyethylene on the surface of the release paper body 5 to form a preliminary coating. The release paper body 5 continues to be transported, and the arc-shaped scraper 11 is attached to the surface of the release paper body 5 to scrape off the excess polyethylene, so that the coating thickness is uniform and consistent, and preparation is made for subsequent groove pressing.

[0028] On the other hand, the rotating shaft 903 at the bottom of the storage box 7 drives the belt pulley 1 403 to rotate through the belt groove 1 402 and the driving belt 1 404, and the belt pulley 1 403 drives the groove pressing roller 1202 to rotate synchronously. When the release paper body 5 coated with polyethylene is transported between the supporting roller 1201 and the groove pressing roller 1202, the raised lines on the surface of the groove pressing roller 1202 cooperate with the supporting roller 1201 to press clear gas guide grooves on the polyethylene coating. The specifications of the gas guide grooves completely match the raised lines on the groove pressing roller 1202.

[0029] At the same time, the rotating shaft 903 at the bottom of the storage box 7 drives the belt pulley 2 406 to rotate through the belt groove 2 405 and the driving belt 2 407, and the belt pulley 2 406 drives the rotating shaft 903 at the bottom of the storage box 2 8 to rotate, thereby driving the corresponding output pump 9 of the storage box 2 8 to operate. Liquid silicone is pressurized and transported to the distribution box 1001 and the nozzle 1 002, and is coated on the surface of the release paper body 5 on which the gas guide grooves have been pressed. At this time, the air pump 1301 of the air blowing assembly 13 is started to generate high-pressure airflow which is distributed to the nozzle 2 303 through the distribution cylinder 1302. The nozzle 2 303 blows airflow along the direction of the gas guide groove to remove excess liquid silicone in the gas guide groove, ensure the smoothness of the gas guide groove, and make the surface silicone coating more uniform.

[0030] The release paper body 5 that has completed all processing procedures continues to be transported to the paper roll 3, and the paper roll 3 neatly winds up the release paper body 5 to form a gas guide groove release paper product. After the release paper body 5 is completely processed, the driving motor 1401, the air pump 1301, and the power of the paper roll 3 are turned off, the wound product is taken out, the remaining raw materials in the storage box 1 7 and the storage box 2 8 are emptied, and the equipment is cleaned and maintained for next use.

[0031] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
