Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene film waste recycling, and particularly relates to a film dust removal and recycling device. Background Technique

[0002] Polyethylene film is an environmentally friendly material with wide application and recyclability. During the production of polyethylene, waste film materials are often formed due to process errors. These waste materials can be reused after recycling, which is convenient for saving raw materials and environmental protection. When recycling film waste, it is usually necessary to first wind up the waste film through a winding roller, and then send it to a crushing process through a transportation device. However, there are impurities on the surface of the recycled waste film. If it is directly wound up and then recycled and melted to form a new film, the impurities will remain in the film, affecting the product quality of the film. Therefore, it is of great significance to provide a film dust removal and recycling device with an automatic impurity removal function. Content of the Utility Model

[0003] The purpose of this application is to provide a film dust removal and recycling device to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, this application provides the following technical solution: A film dust removal and recycling device, including a processing device housing. A film feeding port is provided at the top of the processing device housing. A first guiding roller is fixedly installed inside the film feeding port. Inside the processing device housing, a second guiding roller and a film winding roller are provided below the first guiding roller. The first guiding roller is located above the film winding roller. The first guiding roller and the second guiding roller guide the polyethylene film waste into the film winding roller for winding. An impurity removal brush wheel is provided between the first guiding roller and the second guiding roller. There are two impurity removal brush wheels located on both sides of the polyethylene film waste. The impurity removal brush wheel is rotationally connected to the processing device housing. Inside the processing device housing, a partition plate is fixedly installed below the impurity removal brush wheel and above the second guiding roller. The partition plate is provided with holes through which the polyethylene film passes. A plurality of air blowing cylinders are fixedly installed at the top of the partition plate, facing the impurity removal brush wheel and away from the polyethylene film.

[0005] Further, a first fan is fixedly installed on one side of the processing device housing. The input end of the first fan is connected to an exhaust duct inside the processing device housing. The output end of the first fan leads into a filter box fixedly installed inside the bottom end of the processing device housing.

[0006] Further, an air outlet extending to the outside of the processing device housing is provided on one side of the filter box. A plurality of impurity filter plates are fixedly installed inside the filter box along the air discharge direction. A material receiving door is installed on one side of the processing device housing where the filter box is located.

A second guiding roller 4 and a film winding roller 5 are provided inside the processing device housing 1 below the first guiding roller 3. The first guiding roller 3 is located above the film winding roller 5. The first guiding roller 3 and the second guiding roller 4 guide the polyethylene film waste to the film winding roller 5 for winding. An impurity removing brush wheel 6 is provided between the first guiding roller 3 and the second guiding roller 4. There are two impurity removing brush wheels 6 located on both sides of the polyethylene film waste. The impurity removing brush wheel 6 is rotatably connected to the processing device housing 1. A partition plate 18 is fixed inside the processing device housing 1 below the impurity removing brush wheel 6 and above the second guiding roller 4. The partition plate 18 is provided with holes through which the polyethylene film passes. A plurality of blowing cylinders 7 facing the impurity removing brush wheel 6 and facing away from the polyethylene film are fixedly installed at the top of the partition plate 18. Such a setting of the blowing cylinders 7 can remove the dust on the impurity removing brush wheel 6 to ensure its impurity removing efficiency. The setting of the partition plate 18 prevents the film at the second guiding roller 4 from falling on dust.

[0021] Through the above technical solution of the present invention, a first fan 9 is fixedly installed on one side of the processing device housing 1. The input end of the first fan 9 is connected to a plurality of exhaust ducts 8 located inside the processing device housing 1. Each exhaust duct 8 sucks away the dust blown away by the corresponding blowing cylinder 7. The output end of the first fan 9 is led into the inside of a filter box 10 fixed to the inner side of the bottom end of the processing device housing 1 to send the dust purged inside the processing device housing 1 into the filter box 10.

[0022] Through the above technical solution of the present utility model, an air outlet 17 extending to the outside of the housing 1 of the processing device is provided on one side of the filter box 10. A plurality of impurity filter plates 16 are fixedly installed inside the filter box 10 along the air discharge direction. A material receiving door 12 is installed on one side of the housing 1 of the processing device where the filter box 10 is located. Open the material receiving door 12 to take out the internal filter box 10, and remove the internal film winding roller for material collection.

[0023] Through the above technical solution of the present utility model, a second fan 11 is fixedly installed on one side of the housing 1 of the processing device. The output end of the second fan 11 communicates with the blowing cylinder 7 to blow air and remove dust.

[0024] Through the above technical solution of the present utility model, a first motor 13 is fixedly installed on one side of the housing 1 of the processing device. The first motor 13 drives the impurity removal brush wheel 6 to remove impurities and clean the film.

[0025] Through the above technical solution of the present utility model, a second motor 14 is fixedly installed on one side of the housing 1 of the processing device. The second motor 14 drives the film winding roller 5 to wind the film.

[0026] The working principle of this utility model: Wind the polyethylene film in the way attached Figure 2 First, fix one end of the polyethylene film to the film winding roller 5, and then lead it out from one side of the second guide roller 4 and one side of the first guide roller 3 in sequence. The first guide roller 3 and the second guide roller 4 guide and tension the polyethylene film. The other end of the film can be released by the unwinding roller installed with the rolled waste film and driven by a motor. The polyethylene film waste is guided to the film winding roller 5 for winding through the first guide roller 3 and the second guide roller 4. During the winding process, the first motor 13 drives the two impurity removal brush wheels 6 to rotate synchronously to reliably brush off the dust and impurities on both sides of the polyethylene film. The surface of the impurity removal brush wheel 6 is made of fluff material, which can remove the impurities on the surface of the polyethylene film. At the same time, the first fan 13 blows air into the blowing cylinder 7. The blowing cylinders 7 on both sides blow air at the fluff parts of the corresponding impurity removal brush wheels 6 to blow away the impurities on the impurity removal brush wheels 6 and ensure the reliable impurity removal effect of the impurity removal brush wheels 6. At the same time, the second fan 11 recovers the dust blown out by the internal first fan 9 into the filter box 10 for reliable filtration. The filtration of multiple impurity filter plates 16 makes the dust stay inside for collection to avoid being discharged and affecting the working environment of the workshop, and timely collect the internal dust to avoid the dust falling on the polyethylene film to be wound below, thus avoiding the problem of low dust removal efficiency.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
