Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic particle extrusion, in particular to a rubber and plastic particle continuous extrusion device. Background Art

[0002] Rubber granules are mainly produced by processing various waste rubber materials including waste rubber, tourist shoe soles, scraps, cable skins, rubber scraps, car mats, car tires and other waste rubber raw materials. When producing and processing rubber granules, a rubber and plastic granule continuous extrusion device is generally used to produce the material.

[0003] Existing technologies such as the patent publication number CN219236094U disclose a continuous extrusion device for rubber and plastic particles. The patent adopts a base, an organic plate is fixedly installed on the left side of the upper surface of the base, and two symmetrical support columns are fixedly installed on the top of the base. A motor is fixedly installed on the right end of the machine plate, and a processing cylinder is fixedly installed between the tops of the two support columns. A rotating rod is fixedly installed on the output end of the motor, and the right end of the rotating rod extends through the inside of the processing cylinder, and a spiral blade is provided on the outer surface of the rotating rod. The top of the processing cylinder is connected to a feed pipe, and a material box and a regulating valve are respectively provided on the top and front of the feed pipe. The middle of the outer surface of the processing cylinder is fixed with a rotating rod. A heating mechanism is fixedly sleeved, and an extrusion die is provided at the right end of the processing cylinder. The equipment of the utility model solves the problem that most of the existing particle extrusion devices for rubber and plastic processing feed the materials directly. Since the rubber and plastic raw materials are large blocks, it is easy for the internal blockage of the device to be caused by the large feeding amount, which leads to low extrusion efficiency of the rubber and plastic material particles. Secondly, most of the existing particle extrusion devices for polymer material processing adopt a simple structure. Since the rubber and plastic materials are extruded into particles after being melted, it is easy for the temperature of the rubber and plastic materials to be high after molding, resulting in collection and adhesion, and lack of effective rapid cooling treatment, which seriously affects the overall processing efficiency and the problem of uneven quality of the later products.

[0004] In daily work, when the equipment is extruding the material, there is a problem that the material is easy to connect together when the equipment is extruding the material, causing the material to stick together after discharge, making it difficult to present granular shape and form. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that materials extruded from the equipment are prone to sticking and clogging the extrusion head, and to propose a continuous extrusion device for rubber and plastic particles.

[0006] The utility model adopts the following technical solutions: a continuous extrusion device for rubber and plastic particles, comprising a bracket, a main body, a material hopper, an extruder and an extrusion head, wherein the bracket is fixedly connected to both ends of the main body, the material hopper is fixedly connected to the upper end of the main body, the extruder is fixedly connected to one end of the bracket, the extrusion head is fixedly connected to the end of the bracket away from the extruder, a shearing device is provided on the surface of the extrusion head, the shearing device comprises a cutter and a limit frame, the limit frame is fixedly connected to the side of the extrusion head, the cutter is arranged at the discharge end of the extrusion head, the limit frame is fixedly connected to a limiting block at one end away from the extrusion head, and the cutter is fixedly connected to a connecting frame at one end away from the extrusion head.

[0007] Furthermore, the connecting frame is slidably connected to the inside of the limit block, and the end of the connecting frame away from the cutter is rotatably connected to a rotating arm. By arranging the cutter on the side of the extrusion head, the material extruded by the extrusion head can be cut, reducing the risk of the material extruded by the extrusion head sticking together when the equipment is in use.

[0008] Furthermore, one end of the rotating arm away from the connecting frame is rotatably connected to a turntable, a first motor is provided on a side of the turntable away from the rotating arm, and an output end of the first motor is fixedly connected to the surface of the turntable.

[0009] Furthermore, a support arm is fixedly connected to the side of the first motor close to the extrusion head, and one end of the support arm away from the first motor is fixedly connected to the surface of the extrusion head.

[0010] Furthermore, a material discharge device is provided inside the material hopper, and the material discharge device includes a rotating rod and a positioning block. The rotating rod is rotatably connected to the inside of the material hopper, and the positioning block is fixedly connected to both ends of the rotating rod. The middle section of the rotating rod is fixedly connected to a pressure plate, and the pressure plate is wheel-shaped.

[0011] Furthermore, both ends of the rotating rod close to the pressure plate are fixedly connected with gathering plates, and the gathering plates are inclined toward the pressure plate. One end of the rotating rod is fixedly connected with a second motor.

[0012] Furthermore, a connecting seat is fixedly connected to the surface of the second motor, and the connecting seat is fixedly connected to the surface of the material hopper. The connection seat is provided to facilitate positioning of the second motor.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. When the material is extruded, the material tends to stick together, causing it to stick together after discharge, making it difficult to form particles. By setting a shearing device, the extruded material can be cut into sections, reducing the stickiness of the material and improving the practicality of the equipment.

[0015] 2. By setting up a discharge device, the material inside the material hopper can be effectively and quickly fed into the main body, which facilitates the discharge of materials. When the equipment is processing, the material inside the material hopper is easy to accumulate at the discharge port, causing the material accumulation equipment to be difficult to operate. The discharge device can quickly discharge the material inside the material hopper, thereby improving the practicality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The discharge device 7 includes a rotating rod 71 and a positioning block 72. The rotating rod 71 is rotatably connected to the interior of the material hopper 3. The positioning block 72 is fixedly connected to both ends of the rotating rod 71. A wheel-shaped pressure plate 73 is fixedly connected to the middle section of the rotating rod 71. The pressure plate 73 is provided to press the material inside the material hopper 3 downward, reducing the risk of material accumulating at the discharge port during operation, making it difficult to discharge the material. Gathering plates 74 are fixedly connected to both ends of the rotating rod 71 near the pressure plate 73. Gathering plates 74 are inclined toward the pressure plate 73. A second motor 75 is fixedly connected to one end of the rotating rod 71. The gathering plates 74 facilitate gathering materials on both sides of the material hopper 3 toward the center.

When the pressure plate 73 and the gathering plate 74 rotate, the material inside the material hopper 3 is squeezed downward to facilitate falling. By setting up the unloading device 7, the material inside the material hopper 3 can be effectively and quickly introduced into the main body 2, which facilitates unloading. When the equipment is processing, the material inside the material hopper 3 is easily accumulated at the unloading port, causing the material accumulation equipment to be difficult to operate.
