[0002] During the production of high-strength, high-shrinkage PE film, it is necessary to clean the dust adhering to its surface. Utility model patent CN221983369U discloses a dust removal device for PE film production. This device solves the problem that existing dust removal equipment, which uses suction to remove dust, easily causes the PE film to be pulled and wrinkled, thus affecting equipment operation. The device includes a mounting platform, with a mounting plate fixedly installed on one side of the top of the platform. Two film conveying rollers are installed on the upper and lower sides of the front of the mounting plate. Fixing connecting strips are fixedly installed on the left and right sides of the front of the mounting plate. A mounting box is fixedly installed on the side of the fixing connecting strips away from the mounting plate. A mounting housing is fixedly installed on the rear side of the mounting plate. An air-blowing dust removal component is located between the two mounting boxes and the interior of the mounting housing. This dust removal device can effectively blow away dust, preventing the PE film from being pulled and wrinkled by suction, thus ensuring dust removal efficiency.

[0003] However, cleaning the dust adsorbed on the PE film surface is inconvenient, and at the same time, collecting and processing the cleaned dust is inconvenient when the device is in use. Utility Model Content

[0004] The purpose of this invention is to provide a dust collector for the production of high-strength, high-shrinkage PE film, which solves the problem that cleaning the dust adsorbed on the surface of PE film is inconvenient, and that collecting and processing the cleaned dust is inconvenient during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collector for producing high-strength, high-shrinkage PE film, comprising a support frame, a support shaft slidably connected inside the support frame, an adjustment mechanism provided on the support shaft, a cover fixedly connected to the end of the support shaft, a brush roller rotatably connected inside the cover, a motor slidably connected to the surface of the support frame, the motor's rotating shaft passing through the support frame and movably connected to the support frame, the motor's rotating shaft passing through the cover and rotatably connected to the cover, a collection mechanism provided on the support frame, and a connecting pipe fixedly connected inside the support frame.

[0006] Preferably, a flexible hose is fixedly connected inside the connecting pipe, and the flexible hose is fixedly connected to the cover. The connection between the connecting pipe and the cover is achieved by providing the flexible hose.

[0007] Preferably, the adjusting mechanism includes a connecting sleeve, which is fixedly connected to the outer side of the support shaft. A screw cylinder is fixedly connected to the surface of the connecting sleeve, and a bidirectional screw is threadedly connected to the inside of the screw cylinder. A limiting plate is fixedly connected to the rear end of the bracket, and the limiting plate and the bidirectional screw are slidably connected. By rotating the bidirectional screw and the screw cylinder to perform threaded movement, the distance between the two brush rollers changes. The brush rollers are driven to rotate by a motor, causing them to brush against the PE film. This allows the device to clean PE films of different thicknesses, thus broadening its applicability and providing more efficient and thorough cleaning.

[0008] Preferably, the collection mechanism includes a collection cylinder, which is fixedly connected to a support and a connecting pipe. An air pump is fixedly installed at the upper end of the collection cylinder. The suction pipe of the air pump passes through the collection cylinder and is fixedly connected to it. A filter screen is fixedly connected inside the collection cylinder. A conical cylinder is fixedly connected inside the collection cylinder. A retaining sleeve is slidably connected to the outer side of the collection cylinder. A support ring is fixedly connected inside the conical cylinder. A connecting rod is slidably connected inside the support ring. A sealing plate is fixedly connected to the upper end of the connecting rod. A stop block is fixedly connected to the lower end of the connecting rod. A spring is provided on the outer side of the connecting rod. The air pump draws air, creating a negative pressure inside the collection cylinder. This allows the sealing plate to easily engage and disengage with the conical cylinder under the elastic action of the spring. This facilitates the collection of dust drawn from the hood into the collection cylinder. Furthermore, the sliding of the retaining sleeve on the collection cylinder makes cleaning of the dust inside the collection cylinder easier.

[0009] Preferably, a retaining ring is fixedly connected to the outer side of the collecting cylinder, and the retaining ring contacts the retaining sleeve. The retaining ring provides support for the retaining sleeve.

[0010] Preferably, the sealing plate is made of rubber and is in contact with the cone. The sealing plate effectively seals the upper end of the cone.

[0011] Preferably, one end of the spring is fixedly connected to the support ring, and the other end of the spring is fixedly connected to the stop block. By providing the spring, the stop block can be easily reset.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses the rotation of a bidirectional screw and a screw barrel to make a spiral motion, thereby changing the distance between the two brush rollers. The brush rollers are driven to rotate by a motor, so that the brush rollers brush the PE film. This allows the device to clean PE films of different thicknesses by brushing, thus making the device more applicable and the cleaning more efficient and thorough.

[0014] 2. This utility model uses an air pump to draw in air, thereby creating a negative pressure inside the collection cylinder. This allows the sealing plate to easily engage and disengage with the cone under the elastic action of the spring, making it easier for the dust drawn into the hood to enter the collection cylinder for collection. Furthermore, the movable sleeve slides on the collection cylinder, making it easy to clean the dust inside the collection cylinder. Attached Figure Description

[0022] Please see Figures 1-3 The adjusting mechanism 3 includes a connecting sleeve 31. The connecting sleeve 31 is fixedly connected to the outside of the support shaft 2. A screw cylinder 32 is fixedly connected to the surface of the connecting sleeve 31. A bidirectional screw 33 is threadedly connected inside the screw cylinder 32. A limiting plate 34 is fixedly connected to the rear end of the bracket 1. The limiting plate 34 and the bidirectional screw 33 are slidably connected. By rotating the bidirectional screw 33 and the screw cylinder 32 to make threaded movements, the distance between the two brush rollers 5 changes. The brush rollers 5 are driven to rotate by the motor 6, so that the brush rollers 5 brush the PE film. This allows the device to brush and clean PE films of different thicknesses, making the device more applicable and the cleaning more efficient and thorough.

[0023] Please see Figure 1 , Figure 4 The collection mechanism 7 includes a collection cylinder 71, which is fixedly connected to a support 1 and a connecting pipe 8. An air pump 72 is fixedly installed at the upper end of the collection cylinder 71. The suction pipe of the air pump 72 passes through the collection cylinder 71 and is fixedly connected to it. A filter screen 73 is fixedly connected inside the collection cylinder 71. A cone cylinder 74 is fixedly connected inside the collection cylinder 71. A retaining sleeve 75 is slidably connected to the outer side of the collection cylinder 71. A retaining ring 76 is fixedly connected to the outer side of the collection cylinder 71, and the retaining ring 76 contacts the retaining sleeve 75. The retaining ring 76 supports the retaining sleeve 75. A support ring 77 is fixedly connected inside the cone cylinder 74. A connecting rod 78 is slidably connected inside the support ring 77. A sealing plate 79, made of rubber, is fixedly connected to the upper end of the connecting rod 78. The sealing plate 79 contacts the cone 74, and the upper end of the cone 74 is sealed by the sealing plate 79. The lower end of the connecting rod 78 is fixedly connected to the stop block 710. A spring 711 is provided on the outside of the connecting rod 78.

By setting the spring 711, the stop block 710 can be easily reset. The air pump 72 draws in the air, thereby creating a negative pressure in the collection cylinder 71. The sealing plate 79 can be easily engaged and disengaged from the cone 74 under the elastic action of the spring 711. This allows the dust drawn in from the cover 4 to easily enter the collection cylinder 71 for collection. The dust in the collection cylinder 71 is easily cleaned by the sliding of the movable stop sleeve 75 on the collection cylinder 71.

[0024] The specific implementation process of this utility model is as follows: In use, the PE film is passed between the two covers 4. According to the PE film thickness adjustment device, the bidirectional screw 33 is manually rotated. The rotation of the bidirectional screw 33 and the screw cylinder 32 create a spiral motion, thereby changing the distance between the two brush rollers 5, causing the brush rollers 5 to contact the PE film. Then, the motor 6 is started, driving the brush rollers 5 to rotate, causing the brush rollers 5 to brush the PE film. This allows the device to clean PE films of different thicknesses, thus broadening its applicability and making the cleaning more efficient and thorough. The air pump 72 is then started, drawing air from the collection cylinder 71. A negative pressure is created, causing the sealing plate 79 and the cone 74 to separate. The sealing plate 79 drives the connecting rod 78 to move, and the connecting rod 78 drives the stop block 710 to move. The movement of the stop block 710 compresses the spring 711, causing the connecting pipe 8 to draw air from the cover 4 through the hose 9. This causes the dust brushed by the brush roller 5 to be drawn into the collection cylinder 71. Then, under the elastic action of the spring 711, the sealing plate 79 and the cone 74 come into contact, making it easier for the dust drawn from the cover 4 to enter the collection cylinder 71 for collection. The moving stop sleeve 75 slides on the collection cylinder 71, making it easier to clean the dust inside the collection cylinder 71.
