Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape production, in particular to an adhesive tape surface coating device for adhesive tape production. Background Art

[0002] Adhesive tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. Therefore, the surface of the tape needs to be coated with glue during the production process.

[0003] After searching, the patent number CN218742798U discloses a tape surface gluing device for tape production. Before the gluing roller works, the device can brush off the dust on the tape surface through a soft brush, and is connected to the connecting cylinder through an air duct, and the connecting cylinder is connected to the dust suction port. After the fan is started, the dust and other impurities can be sucked out through the dust suction port. Not only can the dust be removed more thoroughly, but also dust can be prevented from remaining inside the gluing device body, thereby preventing dust and other impurities from affecting the gluing effect of the tape and effectively improving the production quality of the tape.

[0004] When the soft-bristle brush comes in contact with the tape, static electricity will be generated due to friction, causing some dust to be stuck on the bristles of the brush when the brush is cleaning the dust. At this time, when the soft-bristle brush continues to come into contact with the tape, the dust will stick to the tape again, resulting in incomplete dust removal, which will cause uneven glue application.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model embodiment discloses a device for coating adhesive on the surface of an adhesive tape for producing the adhesive tape.

[0028] The utility model provides Figure 1-3 The adhesive tape surface gluing device shown in the figure for adhesive tape production comprises a gluing box 1, material ports are provided on both sides of the gluing box 1, support rollers 2 are rotatably provided on both sides of the inner walls of the two material ports, a glue outlet hopper 3 is fixedly provided on the top of the inner wall of the gluing box 1, a glue feeding pipe 4 is connected to the top of the gluing box 1, and the bottom of the glue feeding pipe 4 is connected to the glue outlet hopper 3, a motor 5 is fixedly provided on the back side of the gluing box 1, the output end of the motor 5 passes through the gluing box 1 and is fixedly provided with a gluing roller 6, a material receiving hole is provided at the bottom of the gluing box 1, a material receiving box 20 is slidably provided inside the material receiving hole, and the material receiving box 20 is screwed and fixed to the bottom of the gluing box 1;

[0029] A support frame 7 is fixedly provided at the upper end of the outer wall of the glue coating box 1, and a through hole is opened at the top of the support frame 7. Two vertical plates 8 are provided on the inner wall of the through hole through a rotating displacement mechanism. Rollers 9 are rotatably provided at the lower ends of the two vertical plates 8. The outer sides of the two rollers 9 are wrapped with sticky cloths 10, and the sticky cloths 10 are bonded to the outer sides of the rollers 9.

[0030] When the gluing work is in progress, with the support of the support rollers 2 on both sides, the adhesive tape can be stably transported in the glue coating box 1, and at the same time, the motor 5 is started to rotate the glue coating roller 6, and then the glue feeding pipe 4 is connected with the external glue feeding equipment, so that the glue can pass through the glue outlet hopper 3 and be stained on the glue coating roller 6. At this time, under the rotation of the glue coating roller 6, the glue can be transferred to the surface of the adhesive tape, and before the adhesive tape enters the interior of the glue coating box 1, the sticky cloth 10 on the outer side of the rotating roller 9 contacts the surface of the adhesive tape, which can be bonded and removed from the dust on the surface of the adhesive tape, and the dust is avoided from being repeatedly stained on the surface of the adhesive tape as much as possible, so as to ensure the uniformity of the subsequent gluing of the adhesive tape.

[0031] In order to be able to replace the sticky cloth 10 while the tape is continuously conveyed without affecting the dust removal work, Figure 2-3 As shown, the rotation transposition mechanism includes a cross bar 11, which is rotatably arranged in the through hole, and the end of the cross bar 11 passes through the support frame 7 and extends to the outside, and a gear 12 is fixedly sleeved on the rod wall of the cross bar 11, and the gear 12 is located in the through hole, and two rack plates 13 are meshed on the outside, and the bottoms of the two rack plates 13 are fixedly connected to the tops of the two vertical plates 8 respectively;

[0032] A guide hole 14 is formed inside the two rack plates 13 . A guide block 15 is slidably inserted into the guide hole 14 . The longitudinal sections of the two guide blocks 15 are both rectangular. The guide blocks 15 are fixed in the through holes.

[0033] When there is a lot of dust adhered to the outer side of the sticky cloth 10 on one side, the cross bar 11 can be rotated to rotate the gear 12. At this time, the two rack plates 13 that slide in cooperation with the two guide blocks 15 and the guide holes 14 can be driven to move relatively. At this time, the two vertical plates 8 drive the two rollers 9 and the sticky cloth 10 to switch positions and contact the surface of the tape again. The used sticky cloth 10 can then be disassembled without affecting the dust removal work, thereby improving the gluing effect.

[0034] In order to fix the use position of the sticky cloth 10 after the two sticky cloths 10 are switched, and ensure the dust removal stability, as shown in FIG. Figure 3-4 As shown, a connecting block 16 is fixedly sleeved on the outer side of the end of the cross bar 11, a positioning rod 17 is slidably penetrated inside the connecting block 16, two positioning holes for matching the positioning rod 17 are provided on the back side of the support frame 7, a spring 18 is sleeved on the rod wall of the positioning rod 17, both ends of the spring 18 are fixedly connected to the positioning rod 17 and the support frame 7 respectively, and a pull ring 19 is provided at the intersection of the end of the positioning rod 17.

[0035] Before rotating the cross bar 11, pull the pull ring 19 to pull the positioning rod 17 out of the positioning hole and stretch the spring 18. Then, the cross bar 11 can be driven to rotate through the connecting block 16, and the positions of the two sticky cloths 10 can be switched. After the position of the sticky cloth 10 is adjusted, release the pull ring 19, and under the rebound of the spring 18, the positioning rod 17 is reinserted into the positioning hole, so that the position of the cross bar 11 can be fixed, ensuring that the sticky cloth 10 can stably carry out the sticky work.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
