Description

Technical Field

[0001] This utility model relates to the field of stretch film production technology, and in particular to a pressing device for producing packaging stretch film that is easy to clean. Background Technology

[0002] Stretch film is a type of highly elastic and stretchable plastic film primarily used for packaging and protecting goods during transport. It is typically made from polyethylene (PE) as the main raw material, produced through extrusion blow molding or casting processes. This film can be stretched to tightly wrap around goods, forming a secure whole.

[0003] This utility model, with publication number CN221216416U, discloses a pressing device for producing wrapping film that is easy to clean. It includes a frame with a base fixed to its bottom. During use, the pressing rollers of this easy-to-clean wrapping film production pressing device help to adhere the film to the outside of the film roll during winding, providing auxiliary pressing. Simultaneously, while the pressing rollers rotate and press, a bracket is fixed to the front end of the mounting frame. Multiple sets of brushes fixed inside the brackets can assist in scraping and removing large particles of dust and debris adhering to the outside of the pressing rollers during rotation, keeping the pressing components clean and reducing dust particles and debris trapped during film winding. This facilitates external cleaning of the internal pressing components of the pressing device, solving the problem of inconvenient external cleaning of the internal pressing components. When the above-mentioned device cleans the equipment, the foreign objects or dust cleaned remain on the brush, which causes the foreign objects to re-adhere to the roller, reducing the cleaning effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pressing device for producing packaging wrapping film that is easy to clean.

[0005] This utility model is achieved by the following technical solution: a pressing device for producing packaging wrapping film that is easy to clean, including a cleaning mechanism, an adjusting mechanism and a winding mechanism, wherein the cleaning mechanism is located at the top of the adjusting mechanism and the winding mechanism is located on the outer wall of the adjusting mechanism;

[0006] The cleaning mechanism includes a fixed plate, a sliding rod slidably connected inside the fixed plate, a spring sleeved on the outer wall of the sliding rod, a limit plate fixedly connected to the bottom of the sliding rod, a fixed block fixedly connected to the end of the sliding rod away from the limit plate, an adjusting wheel rotatably connected inside the fixed block, a gear fixedly connected to the outer wall of the end of the adjusting wheel near the fixed block, a gear meshing with a first gear, a brush wheel fixedly connected inside the first gear, a collection frame fixedly connected inside the fixed plate, and a suction pipe connected to the bottom of the collection frame.

[0007] Through the above technical solution, when the film contacts the surface of the adjusting wheel, the friction force drives the adjusting wheel to rotate inside the fixed block. The adjusting wheel is fixed to the gear, and the gear meshes with gear one. Gear one is fixed to the brush wheel, causing the brush wheel to rotate inside the fixed block. The brush wheel contacts the surface of the adjusting wheel, cleaning the dust or foreign objects adhering to the surface of the adjusting wheel. The dust is collected uniformly through the suction pipe by the negative pressure inside the collection frame, reducing the possibility of dust being rolled up when the film is rolled up, improving the cleaning effect and ensuring the quality of the film. A sliding rod is fixed at the bottom of the fixed block, and a spring is sleeved on the outer wall of the sliding rod. The spring pushes the fixed block elastically, so that the adjusting wheel applies a certain pressure to the film, preventing wrinkles from appearing when the film is rolled up. The limiting plate limits the sliding rod.

[0008] As a further improvement to the above solution, the adjustment mechanism includes a housing, the suction pipe is fixedly connected inside the housing, a groove is provided on the inner wall of the housing, the fixing plate is slidably connected to the outer wall of the groove, and a threaded rod is threadedly connected inside the fixing plate.

[0009] As a further improvement to the above solution, a fixing block is rotatably connected to the outer wall of the threaded rod, the fixing block is fixedly connected to the inner wall of the outer shell, and a motor is fixedly connected to the end of the threaded rod away from the fixing block.

[0010] As a further improvement to the above solution, the motor is fixedly connected inside the housing, and a support rod is slidably connected inside the end of the fixing plate away from the threaded rod, and the support rod is fixedly connected inside the fixing block.

[0011] Through the above technical solution, the motor drives the threaded rod to rotate, so that the threaded rod is threadedly connected to the fixed plate. At this time, the fixed plate slides on the outer wall of the slide groove, and the support rod guides the fixed plate to ensure its stability. By adjusting the height of the fixed plate, different stretch films can be adjusted at any time to ensure that the stretch film is in the best tension state, thereby improving the flexibility of the equipment.

[0012] As a further improvement to the above solution, the winding mechanism includes a connecting block, which is fixedly connected to the outer wall of the housing, and a limiting groove is formed inside the connecting block.

[0013] As a further improvement to the above solution, a rotating block is rotatably connected to the outer wall of the limiting groove, a connecting rod is fixedly connected inside the rotating block, and a gear is fixedly connected to the outer wall of the end of the connecting rod near the rotating block.

[0014] As a further improvement to the above scheme, gear two is meshed with gear three, and motor one is fixedly connected to the outer wall of gear three, and motor one is fixedly connected inside the connecting block.

[0015] Through the above technical solution, motor one drives gear two to rotate through gear three. At the same time, gear two is fixed to the connecting rod, and a rotating block is fixed on the outer wall of the connecting rod. The rotating block rotates on the outer wall of the limiting groove and limits gear two, ensuring that gear two and gear three can mesh accurately and that the connecting rod can rotate stably, thereby enabling the wrapping film to wrap at a uniform speed.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes friction to rotate the adjusting wheel inside a fixed block when the film contacts its surface. The adjusting wheel is fixed to a gear, which meshes with another gear. This gear is also fixed to a brush wheel, causing the brush wheel to rotate inside the fixed block. The brush wheel contacts the surface of the adjusting wheel, cleaning away dust or foreign objects adhering to it. The dust is then collected through a suction pipe by the negative pressure inside the collection frame, reducing the possibility of dust getting caught in the film during winding and improving the cleaning effect while ensuring the quality of the film. A sliding rod is fixed to the bottom of the fixed block, and a spring is fitted onto the outer wall of the sliding rod. The spring pushes the fixed block elastically, causing the adjusting wheel to apply pressure to the film, preventing wrinkles from forming during winding. A limiting plate limits the sliding rod.

[0018] This invention uses a motor to drive a threaded rod to rotate, causing the threaded rod to connect with a fixed plate. At this time, the fixed plate slides on the outer wall of the groove, while the support rod guides the fixed plate to ensure its stability. By adjusting the height of the fixed plate, different stretch films can be adjusted at any time to ensure that the stretch film is in the optimal tension state, thereby improving the flexibility of the equipment.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment provides a pressing device for producing packaging wrapping film that is easy to clean, including a cleaning mechanism 1, an adjusting mechanism 2, and a winding mechanism 3. The cleaning mechanism 1 is located on top of the adjusting mechanism 2, and the winding mechanism 3 is located on the outer wall of the adjusting mechanism 2.

[0029] The cleaning mechanism 1 includes a fixed plate 101, a sliding rod 102 slidably connected inside the fixed plate 101, a spring 103 sleeved on the outer wall of the sliding rod 102, a limit plate 104 fixedly connected to the bottom of the sliding rod 102, a fixed block 105 fixedly connected to the end of the sliding rod 102 away from the limit plate 104, an adjusting wheel 106 rotatably connected inside the fixed block 105, a gear 107 fixedly connected to the outer wall of the end of the adjusting wheel 106 near the fixed block 105, a gear 107 meshing with a gear 108, a brush wheel 109 fixedly connected inside the gear 107, a collection frame 110 fixedly connected inside the fixed plate 101, and a suction pipe 111 connected to the bottom of the collection frame 110.

[0030] The adjustment mechanism 2 includes a housing 201, a suction pipe 111 fixedly connected inside the housing 201, a groove 202 opened on the inner wall of the housing 201, a fixing plate 101 slidably connected to the outer wall of the groove 202, and a threaded rod 203 threadedly connected inside the fixing plate 101.

[0031] A fixing block 204 is rotatably connected to the outer wall of the threaded rod 203. The fixing block 204 is fixedly connected to the inner wall of the outer shell 201. A motor 205 is fixedly connected to the end of the threaded rod 203 away from the fixing block 204.

[0032] The motor 205 is fixedly connected inside the housing 201. A support rod 206 is slidably connected inside the end of the fixing plate 101 away from the threaded rod 203. The support rod 206 is fixedly connected inside the fixing block 204.

[0033] The winding mechanism 3 includes a connecting block 301, which is fixedly connected to the outer wall of the housing 201. A limiting groove 302 is formed inside the connecting block 301.

[0034] A rotating block 303 is rotatably connected to the outer wall of the limiting groove 302. A connecting rod 304 is fixedly connected inside the rotating block 303. A gear 305 is fixedly connected to the outer wall of the end of the connecting rod 304 near the rotating block 303.

[0035] Gear 2 305 is meshed with gear 3 306, and motor 1 307 is fixedly connected to the outer wall of gear 3 306. Motor 1 307 is fixedly connected inside the connecting block 301.

[0036] The implementation principle of the easy-to-clean wrapping film production pressing device in this application embodiment is as follows: Motor 1 307 drives gear 2 305 to rotate through gear 3 306. At the same time, gear 2 305 is fixed to connecting rod 304. Rotating block 303 is fixed on the outer wall of connecting rod 304. Rotating block 303 rotates on the outer wall of limiting groove 302, limiting gear 2 305, ensuring that gear 2 305 and gear 3 306 can accurately mesh, and ensuring that connecting rod 304 can rotate stably, thereby wrapping the wrapping film at a uniform speed. At the same time, dust suction pipe 111 is connected to the device, and dust suction pipe 111 and... The collection frame 110 is connected, creating a negative pressure inside. When the membrane contacts the surface of the adjusting wheel 106, friction causes the adjusting wheel 106 to rotate inside the fixed block 105. Simultaneously, the adjusting wheel 106 is fixed to the gear 107, which meshes with gear 108, which in turn is fixed to the brush wheel 109. This causes the brush wheel 109 to rotate inside the fixed block 105, while simultaneously contacting the surface of the adjusting wheel 106. This cleans the dust or foreign matter adhering to the surface of the adjusting wheel 106. The dust is then dissipated due to the negative pressure inside the collection frame 110. Dust is collected uniformly through the suction pipe 111, reducing the possibility of dust being entangled during the winding of the stretch film, thereby improving the cleaning effect and ensuring the quality of the stretch film. Simultaneously, a sliding rod 102 is fixed to the bottom of the fixing block 105, and a spring 103 is sleeved on the outer wall of the sliding rod 102. The spring 103 elastically pushes against the fixing block 105, causing the adjusting wheel 106 to apply a certain pressure to the stretch film, preventing wrinkles from forming during winding. At the same time, the limiting plate 104 limits the sliding rod 102. The motor 205 drives the threaded rod 203 to rotate, causing the threaded rod 203 to be threadedly connected to the fixing plate 101. The fixed plate 101 slides on the outer wall of the slide groove 202, while the threaded rod 203 and the fixed block 204 rotate. The fixed block 204 supports the threaded rod 203. There are two fixed blocks 204. A support rod 206 slides inside the end of the fixed plate 101 away from the threaded rod 203. The support rod 206 is fixed to the fixed block 204 and guides the fixed plate 101 to ensure its stability. By adjusting the height of the fixed plate 101, different stretch films can be adjusted at any time to ensure that the stretch film is in the best tension state, thereby improving the flexibility of the equipment.
