Description

Technical Field

[0001] This utility model relates to the technical field of polyethylene film production coating equipment, and in particular to a polyethylene film coating device. Background Technology

[0002] In the production process of polyethylene film, due to the low thickness of polyethylene film, it is necessary to coat the polyethylene film with protective paper to facilitate the transportation and use of the polyethylene film and to prevent damage to the polyethylene film. A coating device is required in the process of bonding the polyethylene film with the protective paper.

[0003] In the existing technology, during the lamination of polyethylene film, it is generally necessary to apply adhesive between the film and the protective paper to ensure that the film and the protective paper adhere tightly to each other. However, because the adhesive is fluid, and in order to ensure that the adhesive completely covers the film and the protective paper and to prevent the problem of curling edges, the amount of adhesive used is generally large. Therefore, during the process of pressing the film and the protective paper together by the roller, the adhesive is easily squeezed out, which not only contaminates the roller, but also easily scratches the film after drying. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polyethylene film coating device to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A polyethylene film coating device includes a mounting panel, and a drying device, a compaction device and a raw material rack are arranged sequentially from left to right at the top of the mounting panel.

[0007] The compaction equipment includes two mounting brackets, which are fixedly connected to the mounting panel and respectively positioned at the center of both sides of the mounting panel. A lower pressure roller is provided at the top of the opposite side of the two mounting brackets, and an electric lifting rod is provided at the top of the two mounting brackets. An upper pressure roller is rotatably provided at the top of the two electric lifting rods, and a glue removal structure is provided on the side wall of the electric lifting rod.

[0008] The adhesive removal structure includes a mounting ring sleeved on the end of the upper pressure roller, and the mounting ring is fixedly connected to the side wall of the electric lifting rod. The bottom end of the mounting ring is fixedly connected to a scraper plate through a spring telescopic rod. The scraper plate has an arc-shaped groove inside, and the arc-shaped groove fits against the outer wall of the lower pressure roller.

[0009] Furthermore, the outer peripheral wall of the lower pressure roller is convex arc-shaped, while the outer peripheral wall of the upper pressure roller is concave arc-shaped, and the upper pressure roller and the lower pressure roller cooperate with each other.

[0010] Furthermore, the drying equipment includes a drying chamber, which is fixedly installed on the top left side of the mounting panel. Guide structures are provided on both sides of the drying chamber, and a curing spotlight is installed at the top inside the drying chamber.

[0011] Furthermore, the guide structure includes a mounting frame, which is fixedly connected to the drying chamber, and two guide rollers are fixedly installed at the top of the mounting frame.

[0012] Furthermore, the raw material rack includes a column, which is fixedly installed on the right side of the mounting panel. The side wall of the column is provided with two rotating shafts, and the ends of the rotating shafts are threadedly connected to limit rods. The side wall of the column, located between the two rotating shafts, is provided with an adhesive application structure.

[0013] Furthermore, the adhesive application structure includes a support plate, with telescopic air rods at both ends of the support plate. Each of the two telescopic air rods has an adhesive application roller at its top end. Positioning rings are rotatably mounted at both ends of the adhesive application rollers. An adhesive applicator is mounted on the outer periphery of the two positioning rings. The side wall of the adhesive applicator has several evenly distributed adhesive outlets.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. A polyethylene film coating device, wherein film material and protective paper are inserted between an upper pressure roller and a lower pressure roller. During the extrusion process, glue is squeezed out and comes into contact with the outer wall of the lower pressure roller. The glue is then collected by a scraper. The arc groove allows the scraper to fully contact the lower pressure roller, so as to scrape off the glue on the surface of the lower pressure roller and collect it in the collection groove. This effectively prevents glue from adhering to the surface of the lower pressure roller and prevents it from affecting subsequent materials.

[0016] 2. In this polyethylene film coating device, the lower pressure roller is convexly arc-shaped, so that after the material comes into contact with the lower pressure roller, the material forms an arc shape with a high middle and low ends. The upper pressure roller is concave arc-shaped and cooperates with the lower pressure roller. Therefore, the upper pressure roller can apply relatively uniform pressure to the surface of the material. Combined with gravity, the glue can flow from top to bottom, so that excess glue material can be discharged from both sides, which can effectively improve the uniformity of the glue.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 6 The present invention discloses a polyethylene film coating device, including a mounting panel 1. A winding mechanism is provided on the left side of the mounting panel 1 for winding up the bonded and cured material and pulling the material to move along with the winding speed. A drying device 2, a compaction device 3 and a raw material rack 4 are arranged sequentially from left to right at the top of the mounting panel 1.

[0028] The compaction device 3 includes two mounting brackets 31, which are fixedly connected to the mounting panel 1 and respectively arranged in the middle of the two sides of the mounting panel 1. The top of the opposite side of the two mounting brackets 31 is provided with a lower pressure roller 32, and the top of the two mounting brackets 31 is provided with an electric lifting rod 33. The top of the two electric lifting rods 33 is rotatably provided with an upper pressure roller 34, and the side wall of the electric lifting rod 33 is provided with a glue removal structure 35.

[0029] The adhesive removal structure 35 includes an installation ring 351 sleeved on the end of the upper pressure roller 34, and the installation ring 351 is fixedly connected to the side wall of the electric lifting rod 33. The bottom end of the installation ring 351 is fixedly connected to a scraper 352 through a spring telescopic rod. The scraper 352 has an arc-shaped groove 353 inside, and the arc-shaped groove 353 fits against the outer wall of the lower pressure roller 32.

[0030] In this embodiment, as Figure 1 and Figure 6 As shown, during use, the film material to be coated and the protective paper are installed inside the raw material rack 4 respectively. Glue is applied to the opposite sides of the film material and the protective paper through the raw material rack 4. The two raw materials are simultaneously fed into the compaction device 3. The compaction device 3 presses the film material and the protective paper together while removing the overflowing glue.

[0031] Specifically, such as Figure 2 and Figure 5 As shown, when the film material and protective paper are inserted between the upper pressure roller 34 and the lower pressure roller 32, during the extrusion process, the glue will be squeezed out and come into contact with the outer wall of the lower pressure roller 32. At this time, the glue is collected by the scraper 352, and the arc groove 353 allows the scraper 352 to fully contact the lower pressure roller 32 so as to scrape off the glue on the surface of the lower pressure roller 32. The mounting panel 1 is provided with a collection groove 500 at the position corresponding to the scraper 352 to collect the scraped residual glue.

[0032] When the raw material passes through the compaction device 3, the closed film and protective paper are then introduced into the drying device 2, where the adhesive between the film and the protective paper is cured.

[0033] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 5 As shown, the outer peripheral wall of the lower pressure roller 32 is convex arc-shaped, and the outer peripheral wall of the upper pressure roller 34 is concave arc-shaped, and the upper pressure roller 34 cooperates with the lower pressure roller 32.

[0034] In this embodiment, since the lower pressure roller 32 is configured in an outwardly convex arc shape, such as Figure 5 and Figure 2As shown, after the material comes into contact with the lower pressure roller 32, the material forms an arc shape that is high in the middle and low at both ends. At this time, pressure is applied to the material by the upper pressure roller 34, and with the help of gravity, the glue can flow from top to bottom so that the glue material can be fully discharged from both sides. The discharged glue is then guided by the scraper 352 and collected inside the collection tank 500.

[0035] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the drying equipment 2 includes a drying chamber 21, which is fixedly installed on the top left side of the mounting panel 1. Guide structures 22 are provided on both sides of the drying chamber 21, and a curing spotlight 23 is provided at the top inside the drying chamber 21.

[0036] In this embodiment, the guide structures 22 on both sides are used to guide the bonded material so that it can pass through the drying chamber 21, and then the adhesive is cured by the curing spotlight 23.

[0037] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the guide structure 22 includes a mounting frame 221, which is fixedly connected to the drying chamber 21, and two guide rollers 222 are fixedly installed at the top of the mounting frame 221.

[0038] In this embodiment, a mounting frame 221 is used to install two guide rollers 222, and the bonded film material and protective paper are passed between the two guide rollers 222 so that the film material is introduced into the drying chamber 21 through the two guide rollers 222.

[0039] In a further preferred embodiment of this utility model, such as Figure 1 and 4 As shown, the raw material rack 4 includes a column 41, which is fixedly installed on the right side of the mounting panel 1. Two rotating shafts 42 are provided on the side wall of the column 41. The ends of the rotating shafts 42 are threadedly connected to limit rods 43. A glue-applying structure 44 is provided on the side wall of the column 41 at the position between the two rotating shafts 42.

[0040] In this embodiment, the column 41 is used to install two rotating shafts 42 and the adhesive application structure 44. During use, as follows... Figure 6 As shown, the film material roll and the protective paper roll are respectively sleeved on the outer peripheral walls of the two rotating shafts 42, and the rolls are prevented from falling off by the limiting rods 43. At the same time, the glue brushing structure 44 is pressed tightly against the film material 600 and the protective paper 700 to achieve the purpose of limiting the film material and the protective paper. After the film material and the protective paper are inserted into the compaction device 3 to drain excess glue, and after compaction, they are inserted into the drying device 2 for drying and curing.

[0041] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the glue application structure 44 includes a support plate 441. Telescopic air rods 442 are provided at both ends of the support plate 441. Glue application rollers 443 are provided at the top of each of the two telescopic air rods 442. Positioning rings 444 are rotatably provided at both ends of the glue application rollers 443. Glue application rods 445 are provided on the outer peripheral walls of the two positioning rings 444. A plurality of evenly distributed glue outlets 446 are provided on the side walls of the glue application rods 445.

[0042] In this embodiment, two telescopic air rods 442 are respectively installed at the upper and lower ends of the support plate 441, and the telescopic ends of the telescopic air rods 442 are far away from the support plate 441. The glue brushing roller 443 is rotatably mounted on the side wall of the telescopic end of the telescopic air rod 442. In use, the extension length of the telescopic air rod 442 is controlled by the air pump so that the glue brushing roller 443 comes into contact with the film material 600 and the protective paper 700. At this time, the film material and the protective paper can drive the glue brushing roller 443 to rotate during the movement.

[0043] The glue applicator 445 is connected to the glue pump. The glue pump pumps the glue out through the glue outlet 446 and adheres it to the surface of the glue roller 443. As the glue roller 443 moves along with the film material and the protective paper, it applies the glue to the surface of the film material and the protective paper to improve the uniformity of the glue application.

[0044] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
