Description

Technical Field

[0001] This utility model belongs to the field of material mixing technology for PE film production, and particularly relates to a mixing device for PE film production. Background Technology

[0002] PE film, or polyethylene film, refers to film produced from PE granules. PE film is moisture-proof and has low moisture permeability. Depending on the manufacturing method and control measures, polyethylene film (PE) can be used to produce products with different properties, such as low-density, medium-density, high-density polyethylene, and cross-linked polyethylene.

[0003] In the production process of PE film, a mixing device is needed to mix the raw materials in proportion. However, traditional mixing devices rely solely on a motor-driven stirring rod to mix the raw materials. This method makes it difficult for the raw materials at the bottom to be fully mixed, which has an adverse effect on the quality of subsequent mixing.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes a mixing device for PE film production, comprising a mixing tank, a support leg fixedly installed at the bottom of the mixing tank, an electronic discharge valve fixedly installed at the bottom of the mixing tank, a feed pipe fixedly installed on the side wall of the mixing tank, a connecting plate fixedly installed at the top of the mixing tank, a mounting frame fixedly installed on the side wall of the connecting plate, a motor fixedly installed at the end of the mounting frame away from the connecting plate, a stirring mechanism fixedly installed at the output end of the motor, the stirring mechanism comprising a rotating shaft fixedly installed at the output end of the motor, a first bevel gear fixedly installed on the side wall of the rotating shaft, a second bevel gear meshing with the side wall of the first bevel gear, a connecting rod fixedly installed inside the second bevel gear, a flipping plate fixedly installed on the side wall of the connecting rod, and a scraper fixedly installed at the end of the connecting rod away from the second bevel gear.

[0006] In one example, an internal gear ring is fixedly mounted on the side wall of the shaft, and a second gear is rotatably mounted on the top of the connecting disc.

[0007] In one example, the second gear is meshed with an internal gear ring, and an external gear ring is meshed with the sidewall of the second gear.

[0008] In one example, the external gear ring is rotatably mounted inside the connecting disc, and a connecting cylinder is fixedly mounted inside the external gear ring.

[0009] In one example, a rotating disk is fixedly mounted on the side wall of the connecting cylinder.

[0010] In one example, the connecting rod is rotatably mounted inside the connecting cylinder.

[0011] In one example, the scraper is in contact with the inner wall of the mixing tank.

[0012] The mixing device for PE film production proposed in this utility model can bring the following beneficial effects:

[0013] 1. This utility model achieves all-round mixing of materials through a second bevel gear, connecting rod, flipping plate, and scraper. The flipping plate can turn the materials inside the mixing barrel up and down, the scraper can scrape the inner wall of the barrel to ensure that the materials inside are fully stirred, and the rotating disc can drive the materials to generate vortex. This multi-dimensional mixing method greatly improves the uniformity and quality of the mixture, meeting the requirements of PE film production for high-quality mixing.

[0014] 2. This utility model, through the mixing drum and scraper, with the mixing drum having a spherical structure, enables materials to flow more smoothly during the mixing process, reducing material accumulation in corners and uneven mixing, thereby improving the quality and uniformity of the mixture. The scraper can also easily clean the inner wall of the mixing drum, making the discharge smoother. Attached Figure Description
