Description

Technical Field

[0001] The utility model relates to the technical field of release paper gluing, in particular to an automatic gluing and attaching device for release paper. Background Art

[0002] In order to protect the adhesive products, it is often necessary to apply glue on the surface of the products and then attach a layer of release paper. The sticky glue layer is isolated by the release paper, and the release paper needs to be peeled off before using the products to expose the glue layer.

[0003] In the prior art, the glue is often applied on the surface of the products first, and then the release paper is attached for protection. Due to the low smoothness of the surface of some products, the fluidity of the glue on the surface of the products is poor, resulting in uneven distribution. After the release paper is attached, it is impossible to replenish the glue, so improvement is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic gluing and attaching device for release paper to ensure the uniformity of the glue distribution on the surface of the products.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An automatic gluing and attaching device for release paper includes: a base, a bracket, a first guide roller, a second guide roller, a release paper unwinding rack, a glue spreading pipe, a fixed pressure roller and a floating pressure roller. The first guide roller and the second guide roller are arranged on the base at intervals front and back. The bracket is arranged on the base. The fixed pressure roller is arranged in the bracket and above the first guide roller. The release paper unwinding rack is arranged on the bracket and above the fixed pressure roller. A roll of release paper is arranged in the release paper unwinding rack. After the release paper is unwound, it is sent to the second guide roller through the gap between the first guide roller and the fixed pressure roller. A flat plate is arranged on the base between the first guide roller and the second guide roller. The floating pressure roller is suspended above the flat plate. The glue spreading pipe is horizontally arranged in the bracket and in front of the fixed pressure roller. Spray heads pointing to the fixed pressure roller are arranged on the glue spreading pipe at intervals.

[0007] Wherein, a guide sleeve is arranged on the bracket above the flat plate, and a guide rod penetrating upward through the guide sleeve is arranged at the top of the floating pressure roller.

[0008] Wherein, the number of the floating pressure rollers is 2.

[0009] Wherein, a glue supply pipe is arranged at one end of the glue spreading pipe.

[0010] Wherein, the top surface of the flat plate is flush with the top surface of the first guide roller.

[0011] Wherein, the flat plate is made of nylon plate.

[0012] Advantages of the present utility model: An automatic glue - applying and attaching device for release paper. A layer of release agent is cured on the surface of the release paper, and the flatness is high. First, the glue liquid is sprayed on the release paper and leveled downward along the surface of the release paper to ensure the uniformity of distribution. Then, it is attached to the surface of the product, transferring the glue liquid to the surface of the product and using the release paper for attachment and protection, which is convenient for production. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following Figure 1 and further illustrate the technical solution of the present utility model through specific embodiments.

[0015] Such as Figure 1 shown in the automatic glue - applying and attaching device for release paper, which includes: a base 1, a bracket 2, a first guide roller 4, a second guide roller 5, a release - paper unwinding rack 12, a glue - spreading tube 9, a fixed pressure roller 7, and a floating pressure roller 6. The first guide roller 4 and the second guide roller 5 are arranged at intervals front - to - back on the base 1 for guiding the conveyance of the product 15.

[0016] The bracket 2 is arranged on the base 1. The fixed pressure roller 7 is arranged in the bracket 2 and above the first guide roller 4. The release - paper unwinding rack 12 is arranged on the bracket 2 and above the fixed pressure roller 7. In this embodiment, a roll of release paper 11 is arranged in the release - paper unwinding rack 12 for passive unwinding of the release paper 11.

[0017] After the release paper 11 is unwound, it is sent to the second guide roller 5 through the gap between the first guide roller 4 and the fixed pressure roller 7 to achieve the lamination with the product 15 (paper tape or plastic tape). The glue - spreading tube 9 is horizontally arranged in the bracket 2 and in front of the fixed pressure roller 7. The glue - spreading tube 9 can be fixed in the bracket 2 by U - shaped screws, and the structure is stable.

[0018] A supply hose 8 is arranged at one end of the glue - spreading tube 9, externally connected to a glue pump to send the glue liquid into the glue - spreading tube 9. Nozzles 10 pointing to the fixed pressure roller are arranged at intervals on the glue - spreading tube 9. First, the glue liquid is sprayed on the vertically - conveyed release paper 11 by the nozzles 10 and leveled downward along the surface of the release paper 11. A layer of release agent is cured on the surface of the release paper 11, and the flatness is high, ensuring the fluidity and uniform distribution of the glue liquid on the surface of the release paper 11. Then, it is attached to the surface of the product 15, transferring the glue liquid to the surface of the product 15 and using the release paper 11 for attachment and protection in one go.

[0019] A flat plate 3 is provided on the base 1 between the first guide roller 4 and the second guide roller 5. In this embodiment, the top surface of the flat plate 3 is flush with the top surface of the first guide roller 4, so that the product 15 passes through the top surface of the flat plate 3. The flat plate 3 is made of nylon plate, which has good wear resistance and self-lubricating effect, reducing the friction problem.

[0020] The floating pressure roller 6 is suspended above the flat plate 3, and the self-weight of the floating pressure roller 6 is used for rolling the top surface of the release paper 11. In this embodiment, the number of the floating pressure rollers 6 is 2, and the rolling treatment of the top surface of the release paper 11 can be carried out in two times to drive away the bubbles and further improve the uniformity of the distribution of the adhesive liquid on the surface of the product 15.

[0021] As Figure 1 shown, a guide sleeve 14 is provided on the bracket 2 above the flat plate 3. A guide rod 13 is provided at the top of the floating pressure roller 6 and penetrates upward through the guide sleeve 14 to guide the lifting of the floating pressure roller 6, ensuring that the floating pressure roller 6 freely rolls the top surface of the release paper 11 by its own weight and avoiding damaging the release paper due to excessive pressure.

[0022] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
