A pe film anti-stick roller processing apparatus

Abstract

This utility model provides a PE film anti-sticking roller treatment device, belonging to the technical field of anti-sticking roller treatment equipment. It includes a base and a roller body mounted on the base. Symmetrical ear plates are installed on the upper outer wall of the base, and two air pumps are installed on both sides of the base near the ear plates. In this utility model, the air holes on the roller body reduce the contact area between the PE film and the roller body, thereby reducing the probability of adhesion. Simultaneously, the air holes, in conjunction with the air pumps, generate negative pressure at the air holes during film roll winding, quickly adsorbing and fixing the PE film. During removal, air is blown onto the PE film through the air holes, improving the separation efficiency and preventing damage to the film roll due to adhesion during subsequent removal, thus ensuring the quality of the film roll. Furthermore, the multiple airbags that contract during film roll removal can detach the PE film from the area adhering to the outside of the airbags, allowing for faster film roll disassembly while avoiding damage caused by adhesion.

Description

Technical Field

[0001] This utility model relates to the technical field of anti-sticking roller treatment equipment, and more specifically, to a PE film anti-sticking roller treatment equipment. Background Technology

[0002] In the production of PE film, rollers are an essential equipment component, mainly used for operations such as traction, calendering, and cooling of the PE film. However, due to the inherent characteristics of PE film, it is prone to adhesion to the roller surface during production. This adhesion not only affects the surface quality of the PE film, leading to defects such as scratches and wrinkles, and reducing the product qualification rate, but also increases the operating resistance of the equipment, resulting in increased energy consumption, and may even cause equipment failure, affecting the continuity of production.

[0003] In existing technologies, the solution to the problem of PE film sticking to rollers involves applying an anti-stick coating to the roller surface. However, with increased use, this anti-stick coating gradually wears off, reducing its effectiveness. This causes subsequent PE film to still adhere to the roller, potentially damaging the PE film during roll removal and affecting overall quality. Therefore, inventing a PE film anti-stick roller treatment device to solve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a PE film anti-sticking roller processing device, which aims to solve the problem that existing PE film sticking rollers can easily cause damage to the PE film and affect the overall quality when the film roll is removed later.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a PE film anti-sticking roller treatment device, including a base and a roller body disposed on the base. Symmetrical ear plates are installed on the upper outer wall of the base, and two air pumps are installed on both sides of the base near the ear plates.

[0007] The two end sidewalls of the roller body are rotatably connected to the inner wall of the ear plate. A transmission wheel is fixedly connected to the outer wall of one end of the roller body. The two ends of the roller body are respectively provided with a first air inlet groove. A rotary joint is installed on the inner wall of the first air inlet groove. An air pipe connected to an air pump is installed at one end of the rotary joint. A connecting pipe is installed on the inner wall of the first air inlet groove of the roller body. An annular air cavity connected to the connecting pipe is opened on the inner wall of the other end of the roller body. Several air holes are opened on the sidewalls of the first air inlet groove and the annular air cavity.

[0008] Preferably, the outer wall of the rotary joint and the inner wall of the first air inlet groove are rotatably connected, and the connecting pipe and the roller body are integrally formed.

[0009] Preferably, a second air inlet groove is provided at the end of the roller body away from the first air inlet groove, an annular groove is provided on the outer wall of the roller body, and four axially symmetrical air inlets are provided between the annular groove and the first air inlet groove.

[0010] Preferably, four sets of symmetrically arranged limiting grooves are provided on the inner walls of both sides of the annular groove, and four identical airbags are fixedly connected to the outer wall of the annular groove, with the air inlets and air outlets of the airbags connected together.

[0011] Preferably, the outer wall of the airbag is made of metal, the outer arc angle of the airbag is the same as that of the roller, and the two ends of the airbag are fixedly connected to limiting blocks that are slidably connected to the inner wall of the limiting groove.

[0012] Preferably, the surface of the airbag is provided with a cooling groove, the cooling grooves on the outer sides of the four airbags are combined into a threaded groove, and one of the airbags is provided with an air outlet near the inner wall of the cooling groove, and a one-way valve is installed on the inner wall of the air outlet.

[0013] The beneficial effects of this utility model are:

[0014] The air holes set on the roller reduce the contact area between the PE film and the roller, thereby reducing the probability of the PE film and the roller sticking together. At the same time, the air holes, together with the air pump, can quickly adsorb and fix the PE film by drawing air at the air holes when winding the film roll. When taking it out, the air holes blow air onto the PE film, improving the efficiency of separation between the two and avoiding damage to the film roll due to adhesion when removing the film roll later, thus ensuring the quality of the film roll.

[0015] The multiple airbags designed to retract during film roll removal detach the PE film from the area adhering to the outside of the airbags, further reducing the contact area between the PE film and the roller. This allows for faster film roll disassembly and prevents damage caused by adhesion. Furthermore, the cooling grooves on the outside of the airbags, combined with the one-way valves inside, allow air to flow along a spiral path and exit from the other side. During this airflow, air comes into contact with the surface of the PE film, carrying away heat and increasing the cooling speed. This further prevents adhesion between the airbags and the PE film, ensuring efficient film roll disassembly and high-quality finished products. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example, refer to Figures 1-7A PE film anti-sticking roller processing device includes a base 1 and a roller body 2 disposed on the base 1. Symmetrical ear plates 11 are installed on the upper outer wall of the base 1, and two air pumps 12 are installed on both sides of the base 1 near the ear plates 11.

[0027] The two end side walls of the roller body 2 are rotatably connected to the inner wall of the ear plate 11. A transmission wheel is fixedly connected to the outer wall of one end of the roller body 2. The two ends of the roller body 2 are respectively provided with a first air inlet groove 21. A rotary joint 14 is installed on the inner wall of the first air inlet groove 21. An air pipe 13 connected to the air pump 12 is installed at one end of the rotary joint 14. A connecting pipe 22 is installed on the inner wall of the first air inlet groove 21 of the roller body 2. An annular air cavity 23 connected to the connecting pipe 22 is opened on the inner wall of the other end of the roller body 2. Several air holes 24 are opened on the side walls of the first air inlet groove 21 and the annular air cavity 23.

[0028] Furthermore, the outer wall of the rotary joint 14 and the inner wall of the first air inlet groove 21 are rotatably connected, and the connecting pipe 22 and the roller body 2 are integrally formed.

[0029] It should be noted that a drive wheel is installed at one end of the roller body 2. During winding, the roller body 2 is wound by a motor in conjunction with a drive belt. At the same time, the surface of the roller body 2 is coated with an anti-stick coating. During winding, the air pump 12 near the first air inlet groove 21 is activated to extract air from the first air inlet groove 21. Simultaneously, under the action of the connecting pipe 22, air is extracted from the annular air chamber 23. Outside air is drawn into the first air inlet groove 21 and the annular air chamber 23 through the air hole 24. At this time, a negative pressure is generated at the air hole 24, causing the two sides of the PE film to adhere tightly to the outer wall of the roller body 2. After fixing one end of the PE film, it is wound up. The suction force generated by the negative pressure adsorbs the PE film onto the outer wall of the roller 2, which can quickly wind it up. At the same time, the setting of the air hole 24 reduces the contact area between the PE film and the roller 2, thereby reducing the probability of the PE film and the roller 2 sticking together. When the film roll is taken out, the air pump 12 is controlled to inflate the first air inlet groove 21, so that the air hole 24 blows air onto the PE film, improving the separation efficiency between the two and avoiding damage to the film roll due to adhesion when the film roll is taken out later, thereby ensuring the quality of the film roll.

[0030] Furthermore, a second air inlet groove 25 is provided at the end of the roller body 2 away from the first air inlet groove 21. An annular groove 26 is provided on the outer wall of the roller body 2. Four axisymmetric air inlets 28 are provided between the annular groove 26 and the first air inlet groove 21. Four sets of axisymmetrically arranged limiting grooves 27 are provided on the inner walls of both sides of the annular groove 26. Four identical airbags 3 are fixedly connected to the outer wall of the annular groove 26. The air inlets of the airbags 3 are connected to the air inlets 28. The outer wall of the airbags 3 is made of metal. The outer arc angle of the airbags 3 is the same as that of the roller body 2. Limiting blocks 31 that slide and connect with the inner wall of the limiting grooves 27 are fixedly connected to both ends of the airbags 3. Cooling grooves 32 are provided on the surface of the airbags 3. The cooling grooves 32 on the outer sides of the four airbags 3 are combined into a threaded groove. An air outlet 33 is provided on the inner wall of one of the airbags 3 near the cooling groove 32. A one-way valve 34 is installed on the inner wall of the air outlet 33.

[0031] It should be noted that before winding, the air pump 12 near the second air inlet groove 25 is started to inflate the inside of the second air inlet groove 25. Air enters the inside of the airbag 3 through the second air inlet groove 25 and the air inlet 28. At this time, the air pressure inside the airbag 3 increases and expands outward. Through the action of the limiting block 31 and the limiting groove 27, the arc plate on one side of the airbag 3 is pushed outward until it is flush with the curved surfaces at both ends of the roller body 2, thus forming a complete roller body 2 to wind the PE film. At the same time, when the PE film is removed later, the air pump 12 can be used to evacuate the first air inlet groove 21, thereby reducing the air pressure inside the airbag 3 and causing it to contract. During the contraction of the airbag 3, the PE film can be separated from the area of ​​adhesion on the outside of the airbag 3, thereby further reducing the contact area between the PE film and the roller body 2. This allows for faster disassembly of the film roll and avoids damage to the film roll due to adhesion.

[0032] Meanwhile, the outer wall of the airbag 3 is provided with a cooling groove 32. The cooling grooves 32 between multiple airbags 3 are combined into a spiral groove. After the airbag 3 is fully inflated, the air pump 12 continues to inflate the second air inlet groove 25 and the airbag 3. At this time, the air pressure inside the airbag 3 increases, forcing the one-way valve 34 to open and close. At this time, the excess air enters the cooling groove 32. Since the PE film covers the outside of the airbag 3, the air will flow along the spiral path of the cooling groove 32 and be discharged from the other side. During the air flow, it will come into contact with the surface of the PE film, thereby removing the heat from the surface of the PE film and increasing the cooling speed of the PE film. This further avoids the airbag 3 and the PE film from sticking together, which affects the efficiency of subsequent film roll disassembly and the quality of the disassembled product.

[0033] It should be noted that the specific model and specifications of the air pump need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
