Description

Technical Field

[0001] This application relates to the field of blown film machine technology, and in particular to an automatic dust cleaning device for plastic blown film machines. Background Technology

[0002] A plastic blown film machine is a device that heats and melts plastic particles and then blows them into a thin film. There are many types of blown film machines, including those for PE, POF, and others. The films produced by blown film machines are widely used in various fields, depending on their materials and properties. They are suitable for various high-end film packaging, plastic bag films, protective films, and more. Due to their good barrier properties, freshness preservation, moisture protection, frost protection, oxygen barrier, and oil resistance, these films are widely used in both light and heavy-duty packaging.

[0003] The company mainly produces PE film and polyethylene film. During the production process, plastic particles are heated and melted and then blown into a film. This film is prone to static electricity, so it easily attracts dust. Therefore, a dustproof cloth is installed in the film forming part.

[0004] Existing blown film machines use dustproof cloths to protect the film being processed, reducing dust accumulation and facilitating the process. However, during processing, the dustproof cloths easily accumulate debris and dust, and the machines are typically positioned high, making cleaning difficult for workers. This can affect the protective effect and lifespan of the dustproof cloths, causing dust to fall back onto the film and impacting the film's processing quality. Utility Model Content

[0005] The purpose of this application is to address the problem that existing blown film machines use dustproof cloths to protect the film being processed, reducing dust accumulation and facilitating processing. However, during processing, the dustproof cloths easily accumulate debris and dust, and the high placement of blown film machines makes cleaning difficult for workers, thus affecting the protective effect and lifespan of the dustproof cloths. This allows dust to fall back onto the film, impacting the film's processing quality. This application provides an automatic dustproof cloth cleaning device for plastic blown film machines.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An automatic dust cloth cleaning device for a plastic blown film machine includes a frame with two symmetrical placement rods installed on it. Two symmetrical limiting blocks are fixed to one end of the frame, and a motor is fixed on each limiting block. The output end of the motor passes through the limiting block, and a cleaning mechanism is provided between the motor and the frame.

[0008] By adopting the above technical solution and using the cleaning mechanism, the dustproof cloth can be easily cleaned, reducing the accumulation of dust, debris and other impurities. This facilitates the cleaning of the dustproof cloth, reduces the impact on the protective effect and service life of the dustproof cloth, reduces dust falling on the film, and reduces the impact on the film processing quality.

[0009] Furthermore, the cleaning mechanism includes a lead screw fixed to one output end of the motor, a cleaning frame fixed to the lead screw by a ball nut, a cleaning rod rotatably connected inside the cleaning frame, cleaning brushes fixed on the cleaning rod and arranged in an array, and a limiting component provided between the cleaning brushes and the cleaning frame.

[0010] By adopting the above technical solution, the rotation of the motor drives the lead screw to rotate, and the rotation of the lead screw causes the ball nut to move the cleaning frame, and the cleaning brush cleans the dust and other debris on the dustproof cloth.

[0011] Furthermore, the limiting component includes a limiting post fixed on the limiting block, the limiting post slidingly through the cleaning frame, the end of the limiting post away from the limiting block being fixedly connected to the frame body, a cleaning box being fixed on the cleaning frame, and a cleaning component being provided between the cleaning frame and the limiting post.

[0012] By adopting the above technical solution, the cleaning frame moves on the limiting column, thereby restricting the cleaning frame.

[0013] Furthermore, the cleaning component includes a gear fixed to one end of the cleaning rod, and a rack is fixed to one side of the limiting block, with the gear meshing with the rack.

[0014] By adopting the above technical solution, the gear moves on the rack, driving the cleaning rod to rotate, which in turn causes the cleaning brush to rotate and clean the dust cloth, reducing the impact on the service life of the dust cloth and improving the cleaning effect.

[0015] Furthermore, an air inlet pipe is fixed to one end of the cleaning box, a connecting pipe is fixed to the end of the cleaning box away from the air inlet pipe, a collection pipe is fixed to the lower end of the connecting pipe, and an air suction assembly is provided inside the cleaning box.

[0016] By adopting the above technical solution, the suction enters the connecting pipe through the cleaning box, the suction enters the collection pipe through the connecting pipe, and the suction sucks up and cleans the dust on the dustproof cloth through the collection pipe.

[0017] Furthermore, the suction assembly includes a second motor fixed inside the cleaning box, a fan blade fixed at the output end of the second motor, the fan blade corresponding to the connecting pipe, and a collection component disposed between the fan blade and the cleaning box.

[0018] By adopting the above technical solution, the second motor drives the fan blades to rotate and generate suction, which facilitates cleaning.

[0019] Furthermore, the collection component includes a filter screen disposed inside the cleaning box. The filter screen is located on the side of the fan blade away from the second motor. A collection box is fixed to one side of the filter screen, and the collection box, filter screen, and cleaning box are fixed together by bolts.

[0020] By adopting the above technical solution, the inhaled dust enters the cleaning box, is filtered by the filter screen, and the blocked dust and other debris fall into the collection box, which facilitates the collection of dust.

[0021] Furthermore, the collection tube is a horn tube, which is located on one side of the cleaning brush, and the collection box and filter screen extend out of the cleaning box at one end.

[0022] By adopting the above technical solution, the collection pipe is a trumpet-shaped pipe, which makes it easier to increase the cleaning area and facilitates cleaning.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. When cleaning is required, start motor one. The rotation of motor one drives the lead screw to rotate, which in turn causes the ball nut to move the cleaning frame. The cleaning frame moves on the limiting post, which restricts its movement. The movement of the cleaning frame causes the cleaning rod and cleaning brush to move, allowing the cleaning brush to clean dust and other debris from the dustproof cloth. This facilitates cleaning and reduces the impact on film processing quality. The movement of the cleaning rod causes the gear to move on the rack, which in turn drives the cleaning rod to rotate. This causes the cleaning brush to rotate and clean the dustproof cloth, reducing the impact on the service life of the dustproof cloth and improving the cleaning effect. Through the cleaning mechanism, the dustproof cloth is easily cleaned, reducing the accumulation of dust, debris, and other impurities. This facilitates the cleaning of the dustproof cloth, reduces the impact on the protective effect and service life of the dustproof cloth, and reduces the amount of dust falling on the film, thus reducing the impact on film processing quality.

[0025] 2. When the cleaning rack moves, start motor two. Motor two drives the fan blades to rotate and generate suction. The suction enters the connecting pipe through the cleaning box and then the collection pipe. The suction sucks in the dust on the dustproof cloth and cleans it. The movement of the cleaning rack moves the collection pipe. The collection pipe is a trumpet-shaped pipe, which can increase the cleaning area. When used with the cleaning brush, it can improve the cleaning effect. The sucked-in dust enters the cleaning box and is filtered by the filter screen. The blocked dust and other debris fall into the collection box, which facilitates the collection of dust and reduces the possibility of dust falling back into the film, making it easier to clean the dustproof cloth.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses an automatic cleaning device for the dust cover of a plastic blown film machine.

[0034] Reference Figure 1 and Figure 2 The automatic cleaning device for the dust cover of the plastic blown film machine includes a frame 1, on which two symmetrical placement rods 2 are installed. Two symmetrical limiting blocks 3 are fixed at one end of the frame 1. A motor 4 is fixed on the limiting block 3. The output end of the motor 4 passes through the limiting block 3. A cleaning mechanism is provided between the motor 4 and the frame 1.

[0035] During film blowing, the operator fixes the dustproof cloth to the placement rod 2, so that the dustproof cloth corresponds to the film being processed by the film blowing machine, which facilitates protective processing. When cleaning is required, the dustproof cloth can be easily cleaned through the cleaning mechanism, reducing the accumulation of dust, debris and other impurities, making the cleaning of the dustproof cloth easier, reducing the impact on the protective effect and service life of the dustproof cloth, reducing dust falling on the film, and reducing the impact on the film processing quality.

[0036] Reference Figure 3 and Figure 4 The cleaning mechanism includes a lead screw 5 fixed to the output end of motor 4. A cleaning frame 6 is fixed to the lead screw 5 via a ball nut. A cleaning rod 7 is rotatably connected inside the cleaning frame 6. Cleaning brushes 8 are fixed on the cleaning rod 7 and arranged in an array. A limiting component is provided between the cleaning brushes 8 and the cleaning frame 6. The limiting component includes a limiting post 11 fixed to a limiting block 3. The limiting post 11 slides through the cleaning frame 6. The end of the limiting post 11 away from the limiting block 3 is fixedly connected to the frame body 1. A cleaning box 19 is fixed on the cleaning frame 6. A cleaning component is provided between the cleaning frame 6 and the limiting post 11. The cleaning component includes a gear 9 fixed to one end of the cleaning rod 7. A rack 10 is fixed to one side of the limiting block 3. The gear 9 meshes with the rack 10.

[0037] When cleaning is required, motor 4 is started. The rotation of motor 4 drives the lead screw 5 to rotate, which in turn causes the ball nut to move the cleaning frame 6. The cleaning frame 6 moves on the limiting post 11, which restricts its movement. The movement of the cleaning frame 6 causes the cleaning rod 7 and the cleaning brush 8 to move, allowing the cleaning brush 8 to clean dust and other debris from the dustproof cloth. This facilitates cleaning and reduces the impact on the film processing quality. The movement of the cleaning rod 7 causes the gear 9 to move on the rack 10, which in turn drives the cleaning rod 7 to rotate. This causes the cleaning brush 8 to rotate and clean the dustproof cloth, reducing the impact on the service life of the dustproof cloth and improving the cleaning effect. Through the cleaning mechanism, the dustproof cloth is easily cleaned, reducing the accumulation of dust, debris, and other impurities. This facilitates the cleaning of the dustproof cloth, reduces the impact on the protective effect and service life of the dustproof cloth, and reduces the amount of dust falling on the film, thus reducing the impact on the film processing quality.

[0038] Reference Figure 2 and Figure 3 The cleaning box 19 has an air inlet pipe 12 fixed to one end, a connecting pipe 13 fixed to the end of the cleaning box 19 away from the air inlet pipe 12, and a collection pipe 14 fixed to the lower end of the connecting pipe 13. A suction assembly is installed inside the cleaning box 19. The suction assembly includes a second motor 16 fixed inside the cleaning box 19, a fan blade 17 fixed to the output end of the second motor 16, the fan blade 17 corresponding to the connecting pipe 13, and a collection component between the fan blade 17 and the cleaning box 19. The collection component includes a filter screen 18 installed inside the cleaning box 19, located on the side of the fan blade 17 away from the second motor 16, and a collection box 15 fixed to one side of the filter screen 18. The collection box 15, the filter screen 18, and the cleaning box 19 are fixed with bolts. The collection pipe 14 is a horn-shaped pipe located on one side of the cleaning brush 8, and one end of the collection box 15 and the filter screen 18 extends out of the cleaning box 19.

[0039] When cleaning is needed, the cleaning frame 6 moves, and the second motor 16 is started. The second motor 16 drives the fan blade 17 to rotate and generate suction. The suction enters the connecting pipe 13 through the cleaning box 19, and then enters the collection pipe 14 through the connecting pipe 13. The suction sucks up and cleans the dust on the dustproof cloth through the collection pipe 14. The movement of the cleaning frame 6 drives the collection pipe 14 to move. The collection pipe 14 is a trumpet-shaped pipe, which can increase the cleaning area. Together with the cleaning brush 8, it can easily clean the dust and improve the cleaning effect. The sucked-in dust enters the cleaning box 19 and is filtered by the filter screen 18. The blocked dust and other debris fall into the collection box 15, which can facilitate the collection of dust and reduce the situation of dust falling back into the film. By unscrewing the bolt on the collection box 15, the restriction on the collection box 15 is released, and the collection box 15 and the filter screen 18 can be pulled out to facilitate the cleaning of the filter screen 18 and the collection box 15. After completion, it is reset to improve the cleaning effect on the dustproof cloth.

[0040] The implementation principle of the automatic dustproof cloth cleaning device of the plastic blown film machine in this embodiment is as follows: During the processing of the blown film machine, the operator fixes the dustproof cloth to the placement rod 2 so that the dustproof cloth corresponds to the film being processed by the blown film machine, which facilitates protection during processing. When cleaning is required, the motor 4 is started. The rotation of the motor 4 drives the lead screw 5 to rotate. The rotation of the lead screw 5 causes the ball nut to drive the cleaning frame 6 to move. The cleaning frame 6 moves on the limiting post 11 to restrict the cleaning frame 6. The movement of the cleaning frame 6 causes the cleaning rod 7 and the cleaning brush 8 to move, so that the cleaning brush 8 can clean the dust and other debris on the dustproof cloth, which is convenient for cleaning and reduces the impact on the film processing quality. The movement of the cleaning rod 7 causes the gear 9 to move on the rack 10, which drives the cleaning rod 7 to rotate, so that the cleaning brush 8 can rotate to clean the dustproof cloth and reduce the impact on the service life of the dustproof cloth.

[0041] When cleaning is required, the cleaning frame 6 moves, and the second motor 16 is started. The second motor 16 drives the fan blade 17 to rotate and generate suction. The suction enters the connecting pipe 13 through the cleaning box 19, and then enters the collection pipe 14 through the connecting pipe 13. The suction sucks up and cleans the dust on the dustproof cloth through the collection pipe 14. The movement of the cleaning frame 6 moves the collection pipe 14. The collection pipe 14 is a trumpet-shaped pipe, which can increase the cleaning area. Together with the cleaning brush 8, it can improve the cleaning effect. The sucked-in dust enters the cleaning box 19 and is filtered by the filter screen 18. The blocked dust and other debris fall into the collection box 15, which facilitates the collection of dust and reduces the possibility of dust falling back into the film. By unscrewing the bolts on the collection box 15, the restriction on the collection box 15 can be released, and the collection box 15 and the filter screen 18 can be pulled out for easy cleaning of the filter screen 18 and the collection box 15.
