Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to an extruder for producing polyethylene wax. Background Technology

[0002] Polyethylene wax, also known as polymer wax, is widely used due to its excellent cold resistance, heat resistance, chemical resistance, and abrasion resistance. In normal production, this wax can be directly added to polyolefin processing as an additive to increase the gloss and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl acetate, ethylene propylene rubber, and butyl rubber. It can improve the flowability of polyethylene, polypropylene, and ABS, and the release properties of polymethyl methacrylate and polycarbonate. Compared with PVC and other external lubricants, polyethylene wax has a stronger internal lubricating effect. Polyethylene wax is generally produced by extrusion molding. The molding process uses a rotating screw to extrude the heated and molten thermoplastic raw material from a die head with the required cross-sectional shape. Then, it is shaped by a sizing device and cooled and solidified by a cooler to become a product with the required cross-section.

[0003] Polyethylene wax is first heated and plasticized by an extruder, and then formed into a certain shape of strip, sheet or other semi-finished product through an extrusion die. Subsequently, these semi-finished products can be further processed into the final product through calendering, injection molding, blow molding and other molding processes. Existing polyethylene wax extruders can only perform extrusion and it is difficult to complete the shaping at the same time, which makes the overall processing efficiency low.

[0004] To address the aforementioned issues, an extruder for producing polyethylene wax is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an extruder for producing polyethylene wax, which solves the problem in the prior art where polyethylene wax is first heated and plasticized by an extruder, and then formed into a certain shape of strip, sheet or other semi-finished product through an extrusion die. Subsequently, these semi-finished products can be further processed into the final product through calendering, injection molding, blow molding and other molding processes. The existing polyethylene wax extruders perform extrusion alone and it is difficult to complete the shaping at the same time, resulting in low overall processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extruder for producing polyethylene wax, comprising an extrusion mechanism, a shaping mold connected to one side of the extrusion mechanism, a cooling and disassembly mechanism rotatably disposed on one side of the shaping mold, the extrusion mechanism including a conveying component for extruding polyethylene wax raw materials, the shaping mold including a support connected to one side of the conveying component, a washer engaged on one side of the support, the cooling and disassembly mechanism including a retaining ring inserted into the support and engaged, an outer ring screwed to one side of the retaining ring, a cooling pipe inserted into the outer ring, the cooling pipe being evenly distributed inside the retaining ring and the outer ring.

[0007] Preferably, the extrusion mechanism includes a base plate, a side frame is fixedly mounted on one side of the base plate, and the conveying assembly is mounted on one side of the side frame.

[0008] Preferably, the conveying assembly includes a vertically arranged extrusion tube, the interior of which is provided with a spiral conveying component, and the output end of which is provided with a conveying tube.

[0009] Preferably, the shaping mold includes a fixed frame fixedly disposed on one side of the base plate, the fixed frame and the support frame are fixedly connected, and a washer groove for engaging the washer part is provided on one side of the support frame.

[0010] Preferably, the outer end of the support frame is provided with a slot, and the slot is provided with three sets of positioning slots in a circular array, and a first inner mold is fixedly provided inside the support frame.

[0011] Preferably, the cooling disassembly mechanism further includes multiple sets of screws arranged in a circular array and inserted between the retaining ring and the outer ring.

[0012] Preferably, an inner module is fixedly disposed on the first inner mold, and a second inner mold is fixed inside the retaining ring. The second inner mold has an inner mold groove for engaging the inner module.

[0013] Preferably, a plug is fixedly provided on one side of the retaining ring, and three sets of rotating retaining blocks are fixedly provided on the outer side of the plug. A connecting rod is connected to the outer ring of the second inner mold, and the cooling pipe passes through the connecting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The present invention provides an extruder for producing polyethylene wax, which integrates polyethylene wax extrusion and shaping by connecting the conveying component and the shaping mold. The conveying pipe between the extrusion mechanism and the shaping mold is narrow, so cooling and shaping will not affect the subsequent extrusion conveying. At the same time, the continuous conveying of the extrusion mechanism can fully fill the cooling and disassembly mechanism and complete the shaping simultaneously, thereby improving the processing efficiency. This invention initially solves the problem that existing polyethylene wax extruders can only extrude and cannot complete the shaping simultaneously, resulting in low overall processing efficiency.

[0016] 2. The present invention provides an extruder for producing polyethylene wax. Through the setting of a cooling and disassembly mechanism, a support frame is used to connect the cooling and disassembly mechanism. The retaining ring and the outer ring are fixed by screws. The retaining ring is inserted into the support frame. The washer is used for sealing and filling. The cooling pipes are evenly distributed inside the retaining ring and the outer ring to achieve cooling and shaping. This solves the problem that existing polyethylene wax needs to be shaped and the shaped shape can be replaced. Attached Figure Description
