Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a plastic extruder for cable processing. Background Technology

[0002] Plastic extruders are indispensable in cable processing. Currently, commonly used plastic extruders for cable processing mainly feed plastic raw materials into the hopper. The pressure and shearing force generated by the rotating auger allow the material to be fully plasticized and evenly mixed before being extruded to the die head and shaped.

[0003] After normal use, some of the molten plastic adheres to the auger after the extruder stops operating. When cleaning the auger, it is impossible to observe it because the auger is inside the drum, making it unclear whether the auger is clean. This results in impurities in the plastic shells of another type of cable during production, reducing the production quality. Utility Model Content

[0004] The purpose of this invention is to provide a plastic extruder for cable processing, which solves the problem that when cleaning the auger of the extruder, it is impossible to observe whether the auger is clean because it is inside the barrel, thus affecting the quality of subsequent product production.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a plastic extruder for cable processing, comprising a fixed frame, an extrusion barrel disposed above the fixed frame, a feed hopper disposed at the top of the extrusion barrel, a heating plate disposed inside the extrusion barrel, an extrusion head disposed on the right side of the extrusion barrel, a movable frame disposed on the left side of the fixed frame, a motor disposed above the movable frame, a conveying auger disposed at the output end of the motor, a sealing cover disposed on the left side of the conveying auger, the sealing cover being connected to the extrusion barrel via a connecting mechanism, guide mechanisms disposed on the front and rear sides of the fixed frame and the movable frame, and a docking mechanism disposed between the fixed frame and the movable frame.

[0007] Furthermore, the connecting mechanism includes two semi-circular fasteners that cooperate with each other. Each semi-circular fastener has a limiting groove. The left edge of the sealing cap and the extrusion barrel is located in the limiting groove. The two semi-circular fasteners are connected together by a bolt assembly.

[0008] Furthermore, the bolt assembly includes a connecting bolt and a locking nut. A connecting seat is provided on the outer wall of the semi-circular fastener near both ends. After the two semi-circular fasteners are combined together, the connecting bolt passes through the connecting seat and is locked and positioned by the locking nut.

[0009] Furthermore, the guiding mechanism includes a fixed tube and a telescopic rod. The fixed tube is mounted on the fixed frame, the left end of the telescopic rod is mounted on the movable frame, and the right end of the telescopic rod is inserted into the fixed tube.

[0010] Furthermore, a limiting platform is provided at the right end of the telescopic rod, and the size of the limiting platform is larger than the size of the through hole on the left side of the fixed tube.

[0011] Furthermore, the docking mechanism includes docking component one and docking component two. Docking component one is disposed on the movable frame, and docking component two is disposed on the fixed frame. Docking component two is inserted into the slot of docking component one. Docking component one is provided with a locking hole one, and docking component two is provided with a locking hole two. After the locking hole one and the locking hole two are aligned, they are connected by locking connector one and locking connector two.

[0012] Furthermore, a push rod is provided on the top left side of the mobile frame.

[0013] Furthermore, the bottom of the legs of the mobile frame is equipped with casters and adjustable feet.

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