DETAILED DESCRIPTION
[0026] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0027] A plastic pellet extruder with a pelletizing function comprises an extruder 1, a cooling trough 2 is detachably mounted on one side of the extruder 1, a pelletizing mechanism 3 is detachably mounted on the side of the cooling trough 2 away from the extruder 1, the pelletizing mechanism 3 comprises a mounting frame 31 fixedly mounted on the cooling trough 2, a fixing sleeve 32 is penetrated through one side of the mounting frame 31, a sliding push block 33 is slidably mounted inside the fixing sleeve 32, an electric push rod 39 is disposed on the outside of the mounting frame 31, an output end of the electric push rod 39 is fixedly connected to the sliding push block 33, a pressing block 34 is fixedly connected to one end of the sliding push block 33 away from the electric push rod 39, a cutter 37 is slidably disposed on the inner side of the pressing block 34, a top plate 35 is fixedly connected to the top of the mounting frame 31, a top end of the cutter 37 penetrates to the top of the top plate 35 and is fixedly connected to a fixing plate 36, a spring 38 is sleeved on the surface of the cutter 37, and two ends of the spring 38 are respectively fixedly connected to the fixing plate 36 and the top plate 35.
[0028] The specific use process is as follows: the plastic particles enter the extruder 1 through the feed hopper 7, are melted under the operation of the extruder 1, are extruded when passing through the extrusion end 6, and then enter the cooling tank 2 to cool and shape, and then enter the pelletizing mechanism 3 after being shaped by two shaping rollers 4. At this time, the entire pelletizing mechanism 3 is also started, so the electric push rod 39 is also started. Driven by the electric push rod 39, the sliding push block 33 will be pushed to slide in the fixed sleeve 32, and at the same time enter the mounting frame 31, and then the sliding push block 33 will push the pressing block 34 to move in the mounting frame 31. At this time, the cooperation between the pressing block 34 and the inclined surface can push the pelletizing mechanism 3 to move. The knife 37 moves downward, so that the cutter 37 can cut the plastic product into particles, ensuring the normal cutting work. The opening 312 will not be blocked by the cutter 37 when the pressing block 34 moves, ensuring the normal operation of the pressing block 34, providing convenience for the user's work. Part of the cutter 37 will enter the long hole on the adapter block 311 during the cutting work, so that the plastic product can be completely cut off, thereby ensuring the cutting quality of the plastic product, providing convenience for the user's work. When the cutter 37 moves downward, it will slide on the top plate 35, and will also drive the fixing plate 36 to move. At the same time, the fixing plate 36 will also move on the matching hole of the top plate 35. The compression spring 38 is closed, and then the cutter 37 will cut the shaped plastic particles. In addition, a slope is provided on the side of the adapter block 311 facing the sliding push block 33, so that the cut particles will fall under the pelletizing mechanism 3 along the slope. At this time, the user can place a storage frame under the pelletizing mechanism 3 to collect the cut plastic particles, thereby preventing the plastic particles from being scattered everywhere, providing convenience for the user's subsequent work. In this way, by adding a cutting structure to the extruder, the plastic particles can be cut and processed as soon as they are extruded and formed, reducing the cost of purchasing equipment, and will not increase the user's work steps and reduce the user's work intensity. The two shaping rollers 4 are arranged in upper and lower positions, and the plastic product will pass through the two shaping rollers 4 after being formed. The two shaping rollers 4 can further shape the plastic product to ensure the quality of the product, and also guide the transportation of the plastic product, which is convenient for the user's work. The extruded product is lifted by the supporting rod into the cooling trough 2, and then cooled by the water in the cooling trough 2. The product passes under the protective rod 5 and is finally lifted and sent out by another supporting rod, which can protect the product before and after molding, ensure the production quality of the plastic product, and provide convenience for the user's work.
[0029] Therefore, the structural design of the plastic pellet extruder with a pelletizing function is adopted. A pelletizing structure is added to the extruder. The plastic product can be directly pelletized after extrusion and cooling. It no longer needs to be transferred to a pelletizer for pelletizing. This can save more work steps, improve work efficiency, reduce cost investment, and provide convenience for users' work.

[0032] An adapting block 311 is fixedly mounted on the inner side of the mounting frame 31 . The adapting block 311 is located directly below the cutter 37 . A long hole adapted to the cutter 37 is formed on the top of the adapting block 311 .

[0034] An inclined surface is provided at one end of the inner side of the pressing block 34 , and the inclined surface is matched with the cutter 37 . An opening 312 matched with the cutter 37 is provided at the top of the pressing block 34 .
[0035] Specifically, the setting of the pressing block 34, the opening 312 and the inclined surface, and the cooperation between the pressing block 34 and the inclined surface can push the cutter 37 to move downward, so that the cutter 37 can cut the plastic product into particles, ensuring the normal cutting work.

[0039] Specifically, the protection rod 5 and the support rod are arranged so that the extruded product is lifted by the support rod and enters the cooling trough 2. After being cooled by the water in the cooling trough 2, the product passes under the protection rod 5 and is finally lifted and sent out by another support rod. This can protect the product before and after molding, ensure the production quality of the plastic product, and provide convenience for the user's work.
[0040] An extrusion end head 6 is fixedly mounted on one end of the extruder 1 facing the cooling tank 2 , and a feed hopper 7 is connected to the top of the extruder 1 .
[0041] Specifically, the extrusion end 6 and the feed hopper 7 are arranged so that the material enters from the feed hopper 7, is formed and extruded from the extrusion end 6 under the processing of the extruder 1, then enters the cooling tank 2 for cooling, and finally is shaped and enters the pelletizing mechanism 3 to be cut into pellets and sent out, which provides convenience for the user's work.
