Technical Field

[0001] This utility model belongs to the field of rubber processing technology, specifically relating to a hot-feed rubber extruder. Background Technology

[0002] In existing rubber processing technologies, traditional hot-feed rubber extruders have many shortcomings in the material heating and extrusion processes. On the one hand, uneven heating leads to unstable melting states of the material during extrusion, affecting the quality and consistency of the final product.

[0003] Existing extruders have weak driving force for mixing the added rubber, and cannot ensure that the material receives uniform and stable heating during processing, which reduces the uniformity of mixing the rubber material and thus affects the quality and production efficiency of subsequent rubber products. Utility Model Content

[0004] The purpose of this invention is to provide a hot-feed rubber extruder, which aims to solve the problems of weak stirring force of the extruder when adding rubber in the prior art, and the inability to ensure uniform and stable heating of the material during processing, which reduces the uniformity of mixing of rubber materials and thus affects the quality and production efficiency of subsequent rubber products.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hot-feed rubber extruder, comprising:

[0007] Mounting housing;

[0008] A processing shell is disposed inside a mounting shell. Two first heating plates are disposed on the circumferential surface of the processing shell, and a second heating plate is fixedly connected to the lower inner wall of the mounting shell.

[0009] The discharge shell is fixedly connected to one side of the processing shell, and a spiral blade is rotatably connected to the inner wall of one side of the processing shell.

[0010] The stirring extrusion mechanism includes:

[0011] The motor is fixedly connected to one side of the mounting housing, and the output end of the motor movably penetrates through the inner wall of one side of the mounting housing. The output end of the motor is fixedly connected to a drive gear.

[0012] A rotating base, fixedly connected to one side of the driving gear, has a helical blade threaded onto its inner surface and a threaded seat threaded onto its circumferential surface; and

[0013] A rotating assembly is disposed within the machining housing and connected to the drive gear to enhance the rotational strength of the drive gear.

[0014] As a preferred embodiment of this utility model, the rotating assembly includes:

[0015] Multiple driven gears are rotatably connected to one side of the machining housing, and the multiple driven gears mesh with the driving gear;

[0016] An internal gear ring is rotatably connected to one side of the machining housing, and the internal gear ring meshes with multiple driven gears.

[0017] As a preferred embodiment of this utility model, a fixed seat is threadedly connected to the inner circumference of the discharge shell, a conical seat is fixedly connected to one side of the fixed seat, and a conical shell is threadedly connected to the outer surface of the conical seat.

[0018] As a preferred embodiment of this utility model, the lower end of the mounting housing is fixedly connected to two bases, the outer surface of the processing housing is provided with a heat insulation shell, and a protective shell is fixedly connected to one side of the mounting housing.

[0019] As a preferred embodiment of this utility model, the lower inner wall of the mounting housing is fixedly connected with a plurality of limiting seats, and the upper ends of the plurality of limiting seats are fixedly connected with a plurality of support blocks.

[0020] In a preferred embodiment of this utility model, a feeding pipe is fixedly connected to the outer surface of the processing shell, and a funnel is fixedly connected to the upper end of the feeding pipe.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. In this scheme, rubber material is fed into the processing shell through a funnel. The rubber material inside the processing shell is heated by the first heating plate and the second heating plate to reach a suitable extrusion temperature. When the motor starts, it drives the drive gear and the rotating seat to rotate. At the same time, the driven gear meshes with the internal gear ring, which enhances the rotational strength of the drive gear and ensures the stability and efficiency of the extrusion process. This, in turn, drives the spiral blade to rotate inside the processing shell. The rotation of the spiral blade not only pushes the rubber forward but also stirs and mixes it. The rubber material is pushed to the discharge shell by the spiral blade and discharged through the discharge port of the installed extrusion die. This strengthens the stirring and pushing force of the extruder on the added rubber, and at the same time ensures that the material receives uniform and stable heating during the processing, improving the uniformity of the mixing of the rubber material, thereby reducing the quality and production efficiency of the subsequent rubber products.

[0023] 2. In this solution, the fixed seat is installed on the inner circumference of the discharge shell to fix the conical seat and squeeze the discharged rubber. By rotating the conical shell, the inner diameter of the conical seat is reduced, which facilitates the installation of different types of extrusion dies. Attached Figure Description
