Description

Technical Field

[0001] This utility model belongs to the field of polypropylene plastic production technology, and specifically relates to a polypropylene plastic production equipment. Background Technology

[0002] Polypropylene plastic production equipment, also known as screw extruders, relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and uniformly mix the material, which is then formed through a die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and less common multi-screw extruders and screwless extruders.

[0003] Patent CN217021370U describes a cutting mechanism for a plastic extruder used in the production of modified polypropylene. This mechanism allows plastics of acceptable size to be fed through a filter trough and a feeding trough, while unacceptable plastics continue to be cut. This combination of structures solves the problem of uneven plastic cutting size affecting the thermoplastic effect in extruder cutting equipment. However, it cannot control the feeding process and cannot grind the masterbatch, which reduces efficiency when hot-melting the masterbatch. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polypropylene plastic production equipment with the advantage of easy processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polypropylene plastic production equipment, including a conveying barrel, a feeding barrel fixedly connected to the top outer wall of the conveying barrel, a crusher fixedly connected to the outer wall of the feeding barrel, a baffle rotatably connected to the inner wall of the feeding barrel, a hydraulic rod for driving the baffle rotatably connected to the inner wall of the feeding barrel, a conveying device provided on the inner wall of the conveying barrel, an inner core with replaceable size provided at the front end of the conveying device, and an outer casing with replaceable size provided at the front end of the conveying barrel.

[0006] The above technical solution facilitates processing. The hydraulic rod controls the opening and closing of the baffle, thereby controlling the feed flow. The pulverizer grinds and crushes the masterbatch particles, which facilitates the melting of the masterbatch. When the masterbatch is extruded, the inner core and outer jacket can shape the hot melt. The inner core and outer jacket can be changed in size, which makes it convenient to select the size of the processed product.

[0007] Preferably, the feeding barrel includes a crushing barrel, the top outer wall of the crushing barrel is connected to a feeding hopper, and the bottom outer wall of the crushing barrel is connected to a discharge port.

[0008] The above technical solution can achieve the function of processing. The feed hopper and discharge port form a passage, and the raw material will be crushed by the crusher when it passes through the crushing barrel during the movement.

[0009] Preferably, the pulverizer includes an electric motor, and the output end of the electric motor is fixedly connected to a pulverizing wheel.

[0010] The above technical solution can achieve the function of grinding. The electric motor can control the rotation of the crushing wheel to crush the masterbatch and convey it.

[0011] Preferably, the conveying device includes a motor, the output end of which is fixedly connected to a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to a spiral plate.

[0012] The above technical solution can serve as a feeding mechanism. By controlling the rotation of the shaft with a motor, the spiral plate can convey the masterbatch, which is then heated and melted in the heating zone and extruded.

[0013] Preferably, a front axle is fixedly connected to the outer wall of the front end of the rotating shaft, and a connector is fixedly connected to the outer wall of the front axle.

[0014] The above technical solution can serve as a connection, and the connector head is threaded, which facilitates the replacement of the inner core.

[0018] The above technical solution can serve as a plastic film, and the distance between the molding groove and the core column can be used to control the wall thickness of the pipeline.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The hydraulic rod controls the opening and closing of the baffle, thereby controlling the feed flow rate. The masterbatch particles are ground and crushed by the crusher, which facilitates the melting of the masterbatch.

[0021] 2. The feed hopper and discharge port form a passage. When the masterbatch moves through the crushing barrel, it will be crushed by the crusher. The motor can control the rotation of the crushing wheel to crush the masterbatch and convey it. The motor controls the rotation of the shaft, which can allow the spiral plate to convey the masterbatch. After being heated and melted in the heating zone, the masterbatch is squeezed. The connector is threaded to facilitate the replacement of the inner core. The core column is used to process the hollow part of the plastic tube. The distance between the plastic tank and the core column can be used to control the wall thickness of the pipeline. Attached Figure Description
