Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically to a plastic film conveyor roller cleaning mechanism. Background Technology

[0002] In the manufacturing process of plastic film, the raw materials are generally kneaded and cold-mixed, and then extruded and blow-molded to obtain PVC glassine paper base film. The film is then treated with antistatic and heat-sealing coating, cut, and finally inspected before the qualified plastic film is packaged into finished products.

[0003] In the plastic film processing, conveyor rollers are an indispensable equipment component, responsible for transporting the plastic film from one process to another. However, in actual production, the plastic film often adheres to the outer surface of the conveyor rollers due to static electricity or adhesiveness. This not only affects the conveying efficiency of the plastic film but also leads to a decline in product quality due to the stacking and wrinkling of the plastic film.

[0004] Currently, the common method for cleaning plastic film adhering to conveyor rollers is manual cleaning, which is not only inefficient but also increases production costs. In addition, there are some automated cleaning devices, but these devices are often complex in structure, have high maintenance costs, and are not ideal for removing plastic film debris.

[0005] Therefore, in view of the shortcomings of existing technologies, we urgently need a plastic film conveyor roller cleaning mechanism with simple structure and good cleaning effect to solve the problem of difficult cleaning of conveyor rollers in the plastic film processing process.

[0029] 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.

[0030] Please see Figures 1 to 6 The embodiments proposed in this application are as follows: a plastic film conveying roller cleaning mechanism includes a mounting housing 1, and a conveying roller body 3 is rotatably connected to the lower side of the mounting housing 1 for conveying plastic film;

[0031] A fixing block 2 is installed on the outside of the mounting housing 1 to fix the mounting housing 1 to the outer support and prevent it from rotating with the conveyor roller body 3;

[0032] A pre-lifting mechanism 4 is rotatably installed on one side of the inner side of the mounting housing 1 to pre-lift the adhesive plastic film. A corresponding cleaning mechanism 5 is rotatably installed on the inner side of the mounting housing 1 away from the pre-lifting mechanism 4 to handle residual plastic film debris and prevent plastic film debris from returning to the conveyed plastic film.

[0033] Specifically, the pre-lifting mechanism 4 includes a first mounting strip 401, which is rotatably mounted inside the mounting housing 1. A lifting strip 403 is mounted on the side of the first mounting strip 401 near the conveyor roller body 3. The tip of the lifting strip 403 faces the rotation direction of the conveyor roller body 3, so that the plastic film adhering to the surface of the conveyor roller body 3 can be pre-lifted during the conveying process, which facilitates subsequent processing.

[0034] The final cleaning mechanism 5 includes a second mounting strip 501, which is rotatably mounted inside the mounting housing 1. A scraper 502 is mounted on the side of the second mounting strip 501 near the conveyor roller body 3. The tip of the scraper 502 faces the rotation direction of the conveyor roller body 3 and can clean the residual plastic film that has been lifted off the surface of the conveyor roller body 3.

[0035] The second mounting strip 501 has a second discharge hole 11 on one side, which is opened inside the mounting housing 1. The plastic film concentrated at the second mounting strip 501 can be discharged outward from the second discharge hole 11 to avoid accumulation inside the mounting housing 1. Specifically, the air can be pumped out to create negative pressure inside the mounting housing 1 and pull the plastic film outward.

[0036] The first mounting strip 401 and the second mounting strip 501 are respectively mounted on the upper side of the first mounting magnet 402 and the second mounting magnet 503, and the inner side of the mounting housing 1 is mounted with a repulsive magnet 9 corresponding to the first mounting magnet 402 and the second mounting magnet 503. By utilizing the property that like poles of magnets repel each other, the lifting strip 403 and the scraping strip 502 can always be in contact with the outer surface of the conveying roller body 3, so as to ensure the cleaning effect on the plastic film.

[0037] A cleaning component 6 is installed on the inner side of the middle part of the mounting housing 1 to clean the plastic film debris attached to the outer surface of the conveyor roller body 3, so as to prevent the debris from adhering to the outer surface of the conveyor roller body 3 and continuing to convey plastic film. The cleaning component 6 includes a mounting plate 601, which is rotatably installed in the mounting housing 1. A scraper 602 is installed on the side of the mounting plate 601 facing the conveyor roller body 3. The longitudinal section of the scraper 602 is "C" shaped, and the lower side of the scraper 602 is fitted to the outer surface of the conveyor roller body 3, thereby cleaning the plastic film adhering to the surface of the conveyor roller body 3.

[0038] The outer side of the mounting plate 601 is provided with a reserved groove 7 opened in the mounting housing 1 to provide rotation space for the mounting plate 601;

[0039] A cutting block 603 is also installed on the lower side of the scraper 602 to cut some of the more difficult plastic film debris, and then the final cleaning mechanism 5 is used to clean it.

[0040] The mounting plate 601 has a first discharge hole 10 inside the mounting housing 1 on one side, which can discharge the plastic film cleaned by the scraper 602 outward.

[0041] like Figure 6 As shown, the upper side of the mounting plate 601 is also provided with a pressing mechanism 8 installed in the mounting housing 1. The pressing mechanism 8 includes a mounting cavity 801, a spring is provided inside the mounting cavity 801, and a pressing rod 803 is provided on the side of the spring facing the mounting plate 601 and slidably connected to the mounting cavity 801. A limit screw 802 is provided at the end of the spring away from the mounting plate 601 to limit one end of the spring.

[0042] Specifically, the pressing rod 803 uses a spring to always be in contact with the outer surface of the mounting plate 601, so that the mounting plate 601 not only relies on gravity to keep in contact with the outside of the conveyor roller body 3, but also increases the cleaning effect of plastic film debris.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0044] Although embodiments of the present invention have been shown and described, 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.
