Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically a cutting mechanism for a granulator. Background Technology

[0002] A granulator is a device used to process raw materials into small granules through heating, mixing, and extrusion. It is commonly used in the production processes of industries such as plastics, chemicals, and food, and can process large materials into granular forms that are easy to store, transport, and use.

[0003] In the processing of materials such as plastics and rubber, granulators are crucial equipment for turning raw materials into granular products. The cutting mechanism, a key component of the granulator, cuts the extruded strips into granules of a specified length. However, existing granulator cutting mechanisms are relatively simple in function. During the cutting process, the granules often fall directly to the ground for collection, making it difficult to effectively screen them simultaneously. This results in uneven particle size, affecting product quality. Furthermore, the conveying of the cut granules typically relies on separate conveying equipment, increasing the complexity and floor space required. Therefore, it is necessary to design a more sophisticated and integrated granulator cutting mechanism.

[0004] Therefore, a cutting mechanism for a granulator is proposed to solve the problems mentioned above. Utility Model Content

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 In this embodiment, a cutting mechanism for a granulator includes a base 1, on which an extrusion mechanism 4 is provided. The extrusion mechanism 4 includes an extruder and a cooling device. The extruder pushes the plasticized material through the die outlet under the push of the screw to form a continuous strip with a specific cross-sectional shape. The extruded strip then enters the cooling device for cooling and shaping. The base 1 is provided with a cutting mechanism and a conveying mechanism. The cutting mechanism includes a cutting component 2, which includes a bracket 22. A motor 24 is fixedly installed on the bracket 22. The shaft end of the motor 24 passes through the bracket 22 and is fixed with a first gear 29. A rotating rod 25 is provided on the first gear 29. A blade 26 is provided at one end of the rotating rod 25. A second gear 23 is rotatably connected to the inner wall of the bracket 22. The second gear 23 meshes with the first gear 29. A shaft 27 is installed on the second gear 23. A protrusion 28 is provided on the shaft 27.

[0026] The conveying mechanism includes a conveying component 3, which includes a vertical plate 35. A first conveying roller 31 and a second conveying roller 33 are rotatably connected to the vertical plate 35. A conveyor belt 32 is meshed with the first conveying roller 31 and the second conveying roller 33. A third gear 34 is fixedly installed at one end of the second conveying roller 33, and the third gear 34 meshes with the second gear 23.

[0027] A mounting bracket 21 is fixedly installed on the base 1. The mounting bracket 21 is L-shaped and a sliding rod 213 is slidably mounted on the mounting bracket 21.

[0028] The slide bar 213 is a square rod, and the slide bar 213 is set horizontally. One end of the slide bar 213 is provided with a limit plate, and the limit plate is round.

[0029] A spring 215 is fixedly installed on the side of the limiting plate. The spring 215 is wound around the slide rod 213, and one end of the spring 215 is fixedly connected to the surface of the mounting bracket 21.

[0030] A roller 212 is provided at one end of the slide bar 213, and the roller 212 rolls on the shaft 27.

[0031] A connecting rod 214 is fixedly installed on the slide rod 213. The connecting rod 214 is square in shape and is horizontally set. A plug-in frame 210 is fixedly installed at one end of the connecting rod 214.

[0032] The plug-in frame 210 is square in shape, and an installation frame 211 is plugged into the inner wall of the plug-in frame 210. A filter screen is provided on the inner wall of the installation frame 211.

[0033] When granulation is required, the motor 24 and the extrusion mechanism 4 are started. The motor 24 drives the first gear 29 to rotate. When the first gear 29 rotates, it drives the rotating rod 25 to rotate. When the rotating rod 25 rotates, it drives the blade 26 to rotate. The extrusion mechanism 4 includes an extruder and a cooling device. The extruder pushes the plasticized material through the die outlet under the push of the screw to form a continuous strip with a specific cross-sectional shape. The extruded strip enters the cooling device for cooling and shaping. The shaped strip is continuously fed to the blade 26. When the blade 26 rotates, it cuts the strip, thereby realizing granulation.

[0034] The cut particles will fall onto the filter screen inside the mounting frame 211. At the same time, when the first gear 29 rotates, it will drive the second gear 23 to rotate because the first gear 29 meshes with the second gear 23. When the second gear 23 rotates, it will drive the shaft 27 to rotate. Due to the setting of the spring 215, the roller 212 at one end of the slide rod 213 is in close contact with the surface of the shaft 27. Therefore, when the shaft 27 rotates, when the roller 212 passes the protrusion 28, it will drive the slide rod 213 to shake. When the slide rod 213 shakes, it will drive the particles on the inner wall of the mounting frame 211 to shake through the connecting rod 214 and the insertion frame 210, thereby achieving the purpose of screening particles. Particles that meet the requirements will fall onto the conveyor belt 32 through the filter screen inside the mounting frame 211.

[0035] During the rotation of the second gear 23, the third gear 34 will be driven to rotate. When the third gear 34 rotates, it will drive the second conveyor roller 33 to rotate. The second conveyor roller 33, together with the first conveyor roller 31, will drive the conveyor belt 32 to convey particles, thereby achieving the purpose of conveying particles.

[0036] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0037] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
