Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically a PVC granulator with a screening function. Background Technology

[0002] The main working method of PVC granulators is wet granulation. By using a certain amount of water or steam, the basic waste material is moistened in the cylinder and undergoes a full chemical reaction. Under certain liquid phase conditions, the rotation of the cylinder causes the material particles to agglomerate into spheres due to the extrusion pressure. As the core equipment for processing polyvinyl chloride raw materials into granular finished products, PVC granulators are widely used in the production of pipes, sheets, injection molding and other processes.

[0003] To ensure the uniformity of the finished granules, existing granulators usually have a screen installed below the discharge port to remove unqualified granules such as clumps and powder. However, during the high-temperature extrusion and cooling process, PVC granules are prone to sticking and clumping, which can cause the screen mesh to become clogged. Therefore, a PVC granulator with a screening function is needed. Utility Model Content

[0004] The purpose of this invention is to provide a PVC granulator with a screening function, which solves the problems mentioned in the background art.

A frame is fixedly connected to the end face of the piston rod of the first electric push rod. A screen is fixedly connected inside the frame. A connecting plate is fixedly connected to one outer wall of the base plate. A second electric push rod is fixedly connected to the top of the connecting plate. A connecting rod is threaded to the end of the piston rod of the second electric push rod. A rubber hammer is fixedly connected to the top of the connecting rod.

[0006] In use, first start the motor. The motor's output shaft drives the conveying screw to rotate, which transports the PVC material along the conveying cylinder to the die head. Under the pressure of the extrusion, the material is extruded through the evenly distributed extrusion holes on the die head. With the cooperation of the motor and the cutting blade, the extruded material strips are cut into granules, which are then screened by a screen. Qualified granules fall into the collection box for collection. When the screen mesh is clogged, the piston rod of the first electric push rod pushes the frame and screen to move horizontally, positioning the screen above the rubber hammer. Then, the piston rod of the second electric push rod pushes the rubber hammer to move up and down reciprocally, continuously striking the screen. While striking, the first electric push rod also moves the screen, adjusting the position of the screen being struck. The striking vibration can quickly clear the clogged mesh of the screen, and the connecting rod allows for quick replacement of damaged rubber hammers, making it convenient and practical.

The conveying screw can transport PVC material along the conveying cylinder to the die head. Under the action of extrusion pressure, the material is extruded through the evenly distributed extrusion holes on the die head. With the cooperation of the motor and the cutting blade, the extruded material strip can be cut into granules.

[0009] Optionally, a total of five cutting blades are provided, and the five cutting blades are distributed in a ring shape.

While tapping, the first electric push rod can also push the screen to move and adjust the position of the screen being tapped, which can quickly clean the screen holes that are blocked. Furthermore, the connecting rod can also quickly replace the damaged rubber hammer. Through the cooperation of the above structures, the screen can be cleaned simply and effectively.
