Description

Technical Field

[0001] This utility model belongs to the field of plastic film processing technology, specifically relating to a flame-retardant PE film surface treatment equipment. Background Technology

[0002] Flame-retardant PE film is widely used in electronics, building materials, and packaging materials due to its excellent flame-retardant properties and mechanical strength. However, during the production, transportation, or storage of flame-retardant PE film, its surface easily adsorbs dust, fibers, and other foreign matter. These impurities not only affect the appearance quality of the product but may also reduce the electrical insulation performance of the film or cause defects in subsequent lamination processes. In the prior art, dust-adhesive rollers are usually used to remove dust from the surface of the flame-retardant PE film. For example, the prior patent with publication number CN222306581U discloses "a PE film surface treatment device. It includes a worktable, support legs at the bottom of the worktable, and a fixed frame at the top of the worktable. A feeding device is provided at the upper right side of the fixed frame, and a receiving device is provided at the upper left side of the fixed frame." Its principle is to adsorb tiny particles on the surface of the film material through the adhesive layer on the surface of the dust-adhesive roller, thereby achieving surface cleaning treatment of the flame-retardant PE film.

[0003] However, in actual use, the high-speed friction between the adhesive roller and the flame-retardant PE film during the traditional PE film surface treatment equipment generates local high temperatures. The flame-retardant PE film usually contains halogen or phosphorus-based flame retardants, which are prone to migration at high temperatures, resulting in uneven flame-retardant performance on the film surface and reducing the weight of the product after flame-retardant PE film surface treatment. In addition, the height of the adhesive roller in the existing equipment is mostly fixed, which cannot adapt to film materials of different thicknesses or tensions. When the tension of the PE film is insufficient, poor contact between the PE film and the adhesive roller is likely to occur, resulting in a decrease in the surface dust removal effect. Therefore, this utility model proposes a flame-retardant PE film surface treatment equipment. Utility Model Content

[0004] The purpose of this invention is to provide a flame-retardant PE film surface treatment device to solve the problems mentioned in the background art. In actual use, the high-speed friction between the dust-adhesive roller and the flame-retardant PE film during the treatment process generates local high temperatures. The flame-retardant PE film usually contains halogen or phosphorus-based flame retardants, which are prone to migration at high temperatures, resulting in uneven flame-retardant performance on the film surface and reducing the weight of the product after flame-retardant PE film surface treatment. Furthermore, the existing equipment's dust-adhesive roller height is mostly fixed, which cannot adapt to film materials of different thicknesses or tensions. When the tension of the PE film is insufficient, poor contact between the PE film and the dust-adhesive roller is likely to occur, leading to a decrease in the surface dust removal effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant PE film surface treatment device, comprising a dust removal channel, a dust-adhesive roller installed inside the dust removal channel, dust-adhesive paper disposed on the surface of the dust-adhesive roller, and two support guide rollers rotatably installed on both sides of the dust removal channel, wherein the film material passes over the surface of the dust-adhesive roller and the two support guide rollers, and further comprising...

[0006] The air-cooled heat dissipation assembly installed on the dust removal channel includes an air inlet duct fixed to the top surface of the dust removal channel, a cooling fan installed inside the air inlet duct, and an air inlet opened on the top surface of the dust removal channel and positioned corresponding to the cooling fan, with the cooling fan located directly above the dust-adhesive roller.

[0007] Preferably, the bottom surface of the dust removal channel is provided with an air outlet, and an outlet filter screen is installed inside the air outlet.

[0008] Preferably, an inlet filter screen is installed at the top inner side of the air inlet duct, and the inlet filter screen is located above the cooling fan.

[0009] Preferably, two support plates are symmetrically fixed on both sides of the dust removal channel, and the support guide roller is rotatably installed between the two symmetrical support plates via a rotating shaft.

[0010] Preferably, it also includes an adjustment structure, which includes a strip slide, a threaded support rod, and a fastening ring. The front and rear ends of the dust-adhesive roller are rotatably mounted with threaded support rods, and the front and rear surfaces of the dust removal channel are provided with strip slides corresponding to the threaded support rods. The outer end of the threaded support rod passes through the strip slide to the outside of the dust removal channel and is fitted with a fastening ring. The rear end of the fastening ring is tightly fitted to the dust removal channel.

[0011] Preferably, the fastening ring is threadedly connected to the threaded support rod, and the surface of the fastening ring is provided with anti-slip texture.

[0012] Preferably, both sides of the dust removal channel are open.

[0013] Preferably, the bottom of the dust removal channel is fixed with four support legs, and the four support legs are respectively located at the four corners of the dust removal channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model improves and optimizes the PE film surface treatment equipment in the prior art by designing a wind-cooled heat dissipation component on the dust removal channel. By using forced convection, the surface temperature of the sticky roller is reduced, which inhibits the high-temperature migration of flame retardant during the flame retardant PE film treatment process, ensuring the consistency of surface performance and product quality of the flame retardant PE film after treatment. At the same time, by designing an adjustment structure, the height of the sticky roller is appropriately adjusted to properly tension the film material, ensuring the close adhesion between the flame retardant PE film and the sticky roller, and improving the dust removal efficiency of the flame retardant PE film surface treatment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1 to 5 This is an embodiment of the present invention, which provides a technical solution: a flame-retardant PE film surface treatment device, including a dust removal channel 1, a dust-adhesive roller 6 installed inside the dust removal channel 1, a dust-adhesive paper 61 disposed on the surface of the dust-adhesive roller 6, and two support guide rollers 22 rotatably installed on both sides of the dust removal channel 1, with the film material 4 passing over the surface of the dust-adhesive roller 6 and the two support guide rollers 22. In actual use, this device needs to be installed on a flame-retardant PE film production line so that the film material 4 in the conveying state on the flame-retardant PE film production line passes through the inside of the dust removal channel 1. When passing through, the film material 4 in the conveying state on the flame-retardant PE film production line will contact the dust-adhesive paper 61 on the surface of the dust-adhesive roller 6, and the dust-adhesive paper 61 on the surface of the dust-adhesive roller 6 will remove the fine dust from the surface, achieving the effect of surface treatment of the flame-retardant PE film, thereby realizing the surface cleaning treatment of the flame-retardant PE film.

[0024] The air-cooled heat dissipation assembly installed on the dust removal channel 1 includes an air inlet duct 31 welded and fixed to the top surface of the dust removal channel 1, a cooling fan 33 installed inside the air inlet duct 31, and an air inlet 34 opened on the top surface of the dust removal channel 1 and positioned corresponding to the cooling fan 33. The cooling fan 33 is located directly above the dust-adhesive roller 6 and is connected to an external power source. After operation, it can continuously cool the dust-adhesive roller 6 during its operation, reduce the surface temperature of the dust-adhesive roller 6, prevent the surface temperature of the dust-adhesive roller 6 from becoming too high, inhibit the high-temperature migration of flame retardant during the flame-retardant PE film treatment process, and ensure the consistency of surface performance and product quality after flame-retardant PE film treatment.

[0025] In this embodiment, preferably, an air outlet 35 is provided on the bottom surface of the dust removal channel 1, and an outlet filter 36 is installed inside the air outlet 35 to prevent foreign objects from entering the air outlet 35 and the interior of the dust removal channel 1 from the bottom.

[0026] In this embodiment, preferably, an inlet filter 32 is installed at the top inner side of the air inlet duct 31, and the inlet filter 32 is located above the cooling fan 33 to ensure normal air circulation and prevent foreign objects from accidentally entering the air inlet duct 31.

[0027] In this embodiment, preferably, two support plates 21 are symmetrically welded and fixed on both sides of the dust removal channel 1, and the support guide roller 22 is rotatably installed between the two symmetrical support plates 21 via a rotating shaft. The design of the support guide roller 22 is suitable for supporting and guiding the membrane material 4 when it passes through. At the same time, since the support guide roller 22 is rotatably installed, the membrane material 4 will drive the support guide roller 22 to rotate when it passes through, thereby reducing the conveying resistance of the membrane material 4.

[0028] In this embodiment, preferably, an adjustment structure 5 is also included. The adjustment structure 5 includes a strip slide 51, a threaded support rod 52, and a fastening ring 53. Threaded support rods 52 are rotatably installed at both the front and rear ends of the dust removal roller 6, and strip slides 51 corresponding to the threaded support rods 52 are provided on both the front and rear surfaces of the dust removal channel 1. The outer end of the threaded support rod 52 passes through the strip slide 51 to the outside of the dust removal channel 1 and is fitted with a fastening ring 53. The rear end of the fastening ring 53 is tightly fitted to the dust removal channel 1, achieving high stability of the dust removal roller 6 during daily use. When it is necessary to adjust the height of the dust removal roller 6 to change the tension of the dust removal roller 6 on the film material 4, only... The fastening ring 53 needs to be rotated counterclockwise so that the rear end of the fastening ring 53 is no longer pressed against the dust removal channel 1, which can quickly release the restriction on the threaded support rod 52. At this time, the threaded support rod 52 can be slid up and down in the strip slide 51 to change the height of the sticky roller 6, thereby adjusting the sticky roller 6 to a suitable height, ensuring the tension of the film 4, and ensuring a suitable fit between the sticky roller 6 and the film 4. Then, the fastening ring 53 is rotated clockwise to tighten it again, which can fix the sticky roller 6 at the current height. This achieves rapid adaptive adjustment of the height of the sticky roller 6, meets different tension requirements, and ensures that the sticky roller 6 can maintain a suitable fit with the film 4.

[0029] In this embodiment, preferably, the fastening ring 53 is threadedly connected to the threaded support rod 52, so that the fastening ring 53 can be smoothly rotated and twisted on the surface of the threaded support rod 52. The surface of the fastening ring 53 is provided with anti-slip texture, which can play a certain anti-slip role when the operator twists the fastening ring 53.

[0030] In this embodiment, preferably, both sides of the dust removal channel 1 are open to allow the membrane material 4 to enter and exit smoothly during production and transportation.

[0031] In this embodiment, preferably, four support legs 11 are fixed at the bottom of the dust removal channel 1, and the four support legs 11 are respectively located at the four corners of the dust removal channel 1, for stable support of the dust removal channel 1.

[0032] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
