[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a blown film tube membrane dewatering device, including a fixed frame 1 and a dewatering mechanism 4. The inner wall of the fixed frame 1 is provided with a rotatable rotating mechanism 2. The rotating mechanism 2 includes a drive motor 201, a rotating shaft 202 and an outer tube 203. The drive motor 201 is fixedly installed on one side of the outer wall of the fixed frame 1. The output end of the drive motor 201 is provided with a rotating shaft 202. The outer wall of the rotating shaft 202 is provided with an outer tube 203 of matching size. When the power of the drive motor 201 is turned on, it drives the outer tube 203 installed on the outer wall of the rotating shaft 202 to rotate, which can wind up the blown film tube membrane, thereby cooperating with the dewatering mechanism 4 to automatically dewater the blown film tube membrane.

[0021] A membrane positioning mechanism 3 is fixedly installed on the upper part of the outer wall of the rotating mechanism 2. The membrane positioning mechanism 3 includes a folding piece 301, an arc-shaped piece 302, and a squeezing pad 303. The folding piece 301 is fixedly installed on one side of the outer wall of the outer tube 203. An arc-shaped piece 302 is connected to one side of the outer wall of the folding piece 301. The squeezing pad 303 is bonded to the inner surface of the arc-shaped piece 302. The folding piece 301 is stretched so that it moves the position of the arc-shaped piece 302. The squeezing pad 303 can position the two sides of the membrane of the blown film machine.

[0022] The water removal mechanism 4 is fixedly installed on the front side of the outer wall of the fixed frame 1. The water removal mechanism 4 includes an arc-shaped block 401, a side connecting block 402, a fixing block 403, a water-absorbing pad 404, a mesh pad 405, and a side slot 406. The arc-shaped block 401 is movably connected to the front side of the outer wall of the fixed frame 1. Side connecting blocks 402 are fixedly installed on both sides of the outer wall of the arc-shaped block 401. The fixing block 403 is fixedly installed on the lower front side of the outer wall of the fixed frame 1. The water-absorbing pad 404 is adhered to the upper part of the outer wall of the fixing block 403. The mesh pad 405 is adhered to the upper part of the outer wall of the water-absorbing pad 404. The side slot 406 is opened on both sides of the outer wall of the fixing block 403 to hold the blown film tube. The membrane is placed between the arc-shaped block 401 and the fixed block 403. When the blown film is being wound up, the mesh pad 405 on the water-absorbing pad 404 can absorb water from the surface of the blown film. At the same time, the arc-shaped block 401 is designed with an arc shape and a baffle is installed in front of the arc-shaped block 401. This allows the water on the surface of the blown film to flow to both sides and fall into the mesh pad 405 for collection. A flexible baffle is installed in front of the inner wall of the arc-shaped block 401. This prevents damage to the blown film during water removal and draws the water on the blown film to the position behind the baffle.

[0023] A limiting mechanism 5 is connected to one side of the inner wall of the dewatering mechanism 4. The limiting mechanism 5 includes a limiting rod 501 and a fixing tube 502. The limiting rod 501 is connected and installed on the lower side of the outer wall of the arc-shaped block 401. The fixing tube 502 is fixedly installed on the upper side of the outer wall of the fixing block 403. Moving the arc-shaped block 401 causes the fixing tube 502 to move within the inner wall of the limiting rod 501. This allows for adjustment of the upper and lower positions of the arc-shaped block 401 and the fixing block 403, enabling dewatering close to the surface of the blown film tube.

[0024] Working principle: First, place the device in the designated position, stretch the folding piece 301, causing it to move the position of the arc-shaped piece 302. The extrusion pad 303 can position the two sides of the blown film tube. The blown film tube is placed between the arc-shaped block 401 and the fixed block 403. When the blown film tube is wound up, the mesh pad 405 on the water-absorbing pad 404 can absorb water from the surface of the blown film tube. At the same time, the arc-shaped block 401 is set with an arc-shaped structure, and a baffle is installed in front of the arc-shaped block 401. This allows the water on the surface of the blown film tube to flow to both sides and fall into the mesh pad 405. 5. Water is collected from the blown film tube. The power of the drive motor 201 is turned on, causing the outer pipe 203 installed on the outer wall of the rotating shaft 202 to rotate. This allows the blown film tube to be wound up, and in conjunction with the dewatering mechanism 4, the blown film tube can be automatically dewatered. This allows the arc block 401 to move, causing the fixed pipe 502 to move within the inner wall of the limit rod 501. This allows the upper and lower positions of the arc block 401 and the fixed block 403 to be adjusted, so that they can be close to the surface of the blown film tube for dewatering. This completes the operation process of a blown film tube dewatering device.

[0025] 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.
