Description

Technical Field

[0001] This utility model belongs to the field of plastic granule production technology, and in particular relates to a granule cutting device for the production of modified plastic granules. Background Technology

[0002] Modified plastic granules are a new type of material obtained by modifying plastic raw materials through the addition of various additives and fillers, or by physical and chemical methods. They are classified into types such as reinforcing modification, toughening modification, combustion-supporting modification, UV-resistant modification, and antistatic modification, which enable them to be applied to different industries according to different types. In production, the mixed raw materials are often made into granules by extrusion and other methods.

[0003] In traditional production methods, raw materials are often pressurized by pressure plates to extrude them through extrusion holes. During this process, the raw materials can only be added again after they have all been extruded, and continuous addition is not possible, resulting in low work efficiency and affecting production efficiency. In order to solve the above problems, there is an urgent need for a granule cutting device for the production of modified plastic granules. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in traditional production methods, raw materials are often pressed through a pressure plate to be extruded from an extrusion hole. In this process, the raw materials can only be added again after they are extruded, which cannot be continuously added, resulting in low work efficiency and affecting production efficiency. Therefore, a particle cutting device for the production of modified plastic particles is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a granule cutting device for producing modified plastic granules, comprising a support, a feeding box fixedly connected to the top of the support, an extrusion cylinder fixedly connected to one side of the feeding box, an extrusion plate fixedly connected to the bottom surface of the extrusion cylinder, a cutting component provided on the outer wall of the extrusion cylinder, and a cooling component provided at the bottom end of the extrusion cylinder.

[0006] The cutting assembly includes a motor, the output shaft of which is fixedly connected to a spiral rod. One end of the spiral rod is fixedly connected to a mounting bracket, a blade is fixedly connected to one side of the mounting bracket, a fixing column is fixedly connected to one side of the mounting bracket, and a second pulley is fixedly connected to one side of the fixing column. A belt is drivenly connected to the outer wall of the second pulley.

[0007] As a further description of the above technical solution:

[0008] One end of the motor is fixedly connected to one side of the feed box, and the output shaft of the motor is rotatably connected to it through a through hole opened on one side of the feed box.

[0009] As a further description of the above technical solution:

[0010] The screw rod is rotatably connected to the extrusion cylinder through a through hole at one end, the blade is in contact with the outer wall of the extrusion cylinder, and the mounting bracket is located on the outside of the extrusion cylinder.

[0011] As a further description of the above technical solution:

[0012] The cooling assembly includes a water tank with a filter screen inside. A support base is fixedly connected to the top of the water tank. There are multiple support bases evenly distributed at the top of the water tank. A reciprocating screw is rotatably connected to one side of the support base through a through hole.

[0013] As a further description of the above technical solution:

[0014] On the other side of the support base, a limit rod is fixedly connected through a through hole. One end of the reciprocating screw is fixedly connected to a first pulley, which is connected to a belt drive. A push frame is provided above the filter screen. Both ends of the push frame are slidably connected to mounting sleeves. A spring is fixedly connected inside the mounting sleeve, and the bottom end of the spring is fixedly connected to the push frame.

[0015] As a further description of the above technical solution:

[0016] The mounting sleeve at one end of the push frame is threadedly connected to the reciprocating screw through a threaded hole inside, and the mounting sleeve at the other end of the push frame is slidably connected to the limiting rod through a through hole inside. The limiting rod and the reciprocating screw are symmetrically arranged at the top of the water tank.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] In this invention, a spiral rod is installed inside. During production, raw materials are placed into the feed box and the motor is started. The motor drives the spiral rod to rotate, which in turn drives the raw materials into the extrusion cylinder. Simultaneously, the raw materials are extruded through the holes in the extrusion plate. The rotation of the spiral rod also drives the mounting frame to rotate, causing the blades to cut the raw materials as they pass over the surface of the extrusion plate. This design achieves the goal of using a spiral rod to drive the raw materials into the extrusion cylinder, and as the amount of raw materials increases, the raw materials are extruded through the holes in the extrusion plate and cut into granules by the blades. Furthermore, raw materials can be added to the feed box at any time during the extrusion process, thereby improving production efficiency.

[0019] In this invention, a pusher frame is installed inside. After the blade cuts, the particles fall into the water tank and land above the filter screen. The rotation of the mounting frame drives the second pulley to rotate through the fixed column, which in turn drives the reciprocating screw to rotate through the belt. This causes the pusher frame to slide on the surface of the filter screen, thus pushing the particles to move to both sides of the water tank and slide out. Through this design, after the particles fall into the water tank, they can be pushed out of the filter screen surface in time by the pusher frame, thereby avoiding excessive accumulation of particles on the surface of the filter screen, which gradually rises above the top of the liquid and prevents the particles from cooling in time and sticking together.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4This utility model provides a technical solution: a granule cutting device for producing modified plastic granules, including a support 2, a feeding box 1 fixedly connected to the top of the support 2, an extrusion cylinder 3 fixedly connected to one side of the feeding box 1, an extrusion plate 6 fixedly connected to the bottom surface of the extrusion cylinder 3, a cutting component 5 provided on the outer wall of the extrusion cylinder 3, and a cooling component 4 provided at the bottom end of the extrusion cylinder 3.

[0028] The cutting assembly 5 includes a motor 51, the output shaft of which is fixedly connected to a spiral rod 52. One end of the spiral rod 52 is fixedly connected to a mounting bracket 55. A blade 53 is fixedly connected to one side of the mounting bracket 55. A fixing post 54 is fixedly connected to one side of the mounting bracket 55. A second pulley 56 is fixedly connected to one side of the fixing post 54. A belt 57 is drivenly connected to the outer wall of the second pulley 56.

[0029] One end of the motor 51 is fixedly connected to one side of the feed box 1. The output shaft of the motor 51 is rotatably connected to it through a through hole opened on one side of the feed box 1. The screw rod 52 is rotatably connected to it through a through hole opened at one end of the extrusion cylinder 3. The blade 53 is in contact with the outer wall of the extrusion cylinder 3. The mounting bracket 55 is located on the outside of the extrusion cylinder 3.

[0030] The specific implementation method is as follows: During production, the raw material is put into the feed box 1 and the motor 51 is started. The motor 51 drives the screw rod 52 to rotate and the screw rod 52 drives the raw material into the extrusion cylinder 3. At the same time, as the raw material enters, it is extruded from the holes of the extrusion plate 6. The rotation of the screw rod 52 drives the mounting frame 55 to rotate, which in turn drives the blade 53 to rotate. The blade 53 cuts the raw material when it passes the surface of the extrusion plate 6.

[0031] The cooling assembly 4 includes a water tank 47, within which a filter screen 45 is installed. A support base 46 is fixedly connected to the top of the water tank 47. Multiple support bases 46 are evenly distributed at the top of the water tank 47. A reciprocating screw 43 is rotatably connected to one side of each support base 46 through an internal through-hole. A limit rod 48 is fixedly connected to the other side of each support base 46 through an internal through-hole. A first pulley 44 is fixedly connected to one end of the reciprocating screw 43, and the first pulley 44 is connected to a belt 57 for transmission. A pusher frame 49 is provided above the filter screen 45. Both ends of the pusher frame 49 are slidably connected to mounting sleeves 41. A spring 42 is fixedly connected inside the mounting sleeve 41. The bottom end of the spring 42 is fixedly connected to the pusher frame 49. The mounting sleeve 41 at one end of the pusher frame 49 is threadedly connected to the reciprocating screw 43 through a threaded hole. The mounting sleeve 41 at the other end of the pusher frame 49 is slidably connected to the limiting rod 48 through a through hole. The limiting rod 48 and the reciprocating screw 43 are symmetrically arranged at the top of the water tank 47.

[0032] The specific implementation is as follows: After the blade 53 cuts, the particles fall into the water tank 47 and land on the filter screen 45. The liquid in the water tank 47 cools the particles and causes them to solidify. The rotation of the mounting frame 55 drives the second pulley 56 to rotate through the fixed column 54. This drives the first pulley 44 to rotate through the belt 57, which in turn drives the reciprocating screw 43 to rotate. The reciprocating screw 43 drives the mounting sleeve 41 and the pusher 49 to slide on the surface of the filter screen 45, thereby pushing the particles to move to both sides of the water tank 47 and slide them out. At the same time, because the filter screen 45 has a certain curvature, the pusher 49 will sway up and down when it moves on its surface, which will compress the spring 42 to varying degrees. The reaction force of the spring 42 makes the pusher 49 fit tightly with the filter screen 45.

[0033] Working principle: During production, the raw material is placed into the feed box 1 and the motor 51 is started. The motor 51 drives the screw 52 to rotate, which in turn drives the raw material into the extrusion cylinder 3. As the raw material enters, it is extruded through the holes in the extrusion plate 6. The rotation of the screw 52 drives the mounting frame 55 to rotate, which in turn drives the blade 53 to rotate. The blade 53 cuts the raw material as it passes over the surface of the extrusion plate 6, causing the cut particles to fall into the water tank 47 and onto the filter screen 45. The particles are then degraded by the liquid in the water tank 47. The temperature causes it to solidify, and the rotation of the mounting frame 55 drives the second pulley 56 to rotate through the fixed column 54, which in turn drives the first pulley 44 to rotate through the belt 57 and drives the reciprocating screw 43 to rotate. The reciprocating screw 43 drives the mounting sleeve 41 and the pusher 49 to slide on the surface of the filter screen 45, thereby pushing the particles to move to both sides of the water tank 47 and slide out. At the same time, because the filter screen 45 has a certain curvature, the pusher 49 will sway up and down when it moves on its surface, which will compress the spring 42 to varying degrees. At the same time, the reaction force of the spring 42 makes the pusher 49 fit tightly with the filter screen 45.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
