Description

Technical Field

[0001] The invention belongs to the technical field of PE film production and mixing, in particular to PE film production and mixing equipment. Background Art

[0002] PE film, also known as PE protective film or polyethylene film, is a polymer organic compound film produced from PE particles. PE protective film is the simplest polymer organic compound and the most widely used polymer material in the world today. The produced PE protective film itself has the effect of moisture resistance and low moisture permeability. PE protective film uses special polyethylene plastic film as the base material. According to the density, it is divided into high-density polyethylene protective film, medium-density polyethylene protective film and low-density polyethylene protective film. The main raw material of PE film is polyethylene (PE) particles, which are usually prepared from ethylene monomers through polymerization. In addition to the main PE particles, some auxiliary materials need to be added, such as plasticizers, stabilizers, colorants, antioxidants, antistatic agents, etc. The role of these additives is to improve the performance of PE film or meet specific product requirements. The biggest advantage of PE protective film is that the protected product is not polluted, corroded, or scratched during production, processing, transportation, storage, and use, which protects the original smooth and shiny surface, thereby improving the quality of the product and market competitiveness;

[0003] At present, in the production process of PE film, multiple organic materials need to be uniformly mixed in a mixer. After the mixing is completed, the plug of the discharge pipe needs to be opened to discharge the fully mixed organic materials. However, during the discharge process, a small amount of organic materials will inevitably adhere to the inner wall of the discharge pipe, which is not easy to clean manually. However, if it is left alone for a long time, the material is prone to solidification, resulting in blockage of the discharge at the end of the next mixing, resulting in a slow discharge speed of the organic material.

[0032] A hollow disk 27 is fixedly connected to the top of the screw rod 24, and a plurality of cross bars 28 are fixedly connected around the outer wall of the hollow disk 27. A rubber scraper 29 is fixedly connected to the other end of each cross bar 28, and the other end of each rubber scraper 29 is fitted and rotatably connected to the inner wall of the discharge pipe 11.

When only a small amount of water in the hollow disk 27 is sprayed, there is no resistance pressure on the torsion spring 236, and the torsion spring 236 will immediately drive the L-shaped arc panel 237 to reset.

[0036] A water tank 239 is provided on one side of the telescopic electric cylinder 22, and a water inlet bucket 240 is fixedly connected to the top side of the water tank 239, and a vertical plate 241 is fixedly connected to the outer wall of one end of the water tank 239. The vertical plate 241 and the telescopic electric cylinder 22 are connected through sliding, and the top of the vertical plate 241 is also fixedly connected to the outer wall of one end of the L-shaped fixed plate 21.

[0037] The above scheme is adopted: the water tank 239 containing water will be stretched by the telescopic electric cylinder 22, and the bellows 244 on the vertical plate 241 will be driven synchronously to generate suction force, and the cleaning water in the water tank 239 will be sucked through the water pipe 1 242. The one-way valve 1 243 on the water pipe 1 242 will only make the water in the water tank 239 go out but not go in.

When the hollow plate 27 rotates, the water pipe 245 will slide in a limited manner at the bottom of the hollow plate 27 through the push plate 230 and the slide plate 232, so that the water pipe 245 is positioned and will not rotate with the rotation of the hollow plate 27;

[0039] After the materials on the inner wall of the discharge pipe 11 are cleaned through the reciprocating operation of the telescopic electric cylinder 22, the staff can put water into the water tank 239 through the water inlet bucket 240 installed on the water tank 239, so that the water tank 239 containing the water will be stretched by the telescopic electric cylinder 22, and the bellows 244 on the vertical plate 241 will be driven synchronously to generate a suction force, and the cleaning water in the water tank 239 will be sucked through the water pipe 1 242, and the one-way valve 1 243 on the water pipe 1 242 will only make the water in the water tank 239 go out but not in, and when the telescopic electric cylinder 22 shortens its own length to reset, it will squeeze the bellows 244 in real time, so that the water sucked in the bellows 244 can be introduced into the hollow plate 27 from the water pipe 2 245, and the one-way valve 2 246 on the water pipe 245 will only make the water entering the hollow plate 27 go in but not in The water that comes out and enters the hollow disk 27 will have a certain impact force. The impact resistance pressure of the water flow can easily drive the L-shaped arc panel 237 to rotate 90 degrees on the rotating rod 235, thereby involving the torsion springs 236 at the upper and lower ends of the L-shaped arc panel 237, causing it to twist to its minimum value to produce deformation, and then the water that continuously enters the hollow disk 27 through the water pipe 245 is sprayed through the nozzle 238 in a stamping manner, sprayed onto the inner wall of the discharge pipe 11, and the inner wall is cleaned. When only a small amount of water in the hollow disk 27 is sprayed, there is no resistance pressure on the torsion spring 236, and the torsion spring 236 will immediately drive the L-shaped arc panel 237 to reset. The two different cleaning methods can thoroughly clean the inner wall of the discharge pipe 11, and effectively avoid residual materials attached to the discharge pipe 11.
