Description

Technical Field

[0001] The invention relates to the technical field of cable material granulation, in particular to a high-efficiency cable material granulation device. Background Art

[0002] A pelletizer is commonly used in the pelletizing process of cable materials. The pelletizer includes a feeding device, a conveying device, an extruding device, and a cutting device. The material enters the conveying device through the feeding device. The conveying device compacts and heats the material while conveying it forward. A porous plate is installed between the conveying device and the extruding device. The melted material is filtered and diverted by the porous plate before flowing into the extruding device. The material is cooled in the extruding device. An extrusion plate is installed on the side of the extruding device away from the porous plate. The cooled material is extruded into strips of cable material through the extrusion plate in the extruding device. The cutting device cuts the filamentous material at the extrusion plate into granules, completing the pelletizing of the cable material.

[0003] However, when the pelletizer is stopped, the material in the device cools down and blocks the porous plates, affecting the use of the pelletizer. For this reason, it is urgent to clean the porous plates. For example, the patent with announcement number CN117774173B discloses a high-efficiency pelletizing device for cable materials. The device adjusts the position of the extrusion device and the feeding device through a drive component to increase the spacing between the first porous plate and the second porous plate. The cooled material between the first porous plate and the second porous plate is split and adheres to the first porous plate and the second porous plate respectively, so that the material in the first conical through hole moves with the cooled material and separates from the first porous plate, and the material in the second conical through hole moves with the cooled material and separates from the second porous plate, so that the first and second porous plates can be cleaned easily, reducing the cleaning difficulty and improving the cleaning efficiency.

[0004] However, although this device can reduce the difficulty of cleaning the porous plate, manual cleaning of the porous plate is still required, the cleaning difficulty is still relatively large, and the cleaned materials will also be discarded and wasted. Summary of the Invention

[0014] Preferably, a heat dissipation pipe is wound around the porous member in a circumferential direction.

[0015] Compared with the prior art, the present invention has at least the following advantages: 1. It can effectively prevent the clogging of multiple extrusion holes on porous parts, reducing the difficulty of cleaning porous parts; and the cable material after blowing out is also cut into particles, reducing the waste of cable materials. In the present invention, after the cable material is heated and melted in the extruder, the extruder extrude the cable material into a plurality of extrusion holes on the porous member under the pressure of the plurality of extrusion holes, and then discharges the cable material through the other end of the extrusion holes; under the action of the cutting mechanism, the filamentary material is cut into granules, thereby completing the granulation of the cable material; and after the granulation is completed, the driving component is controlled to move, the driving component drives the porous member to separate from the discharge port of the extruder, and drives the blowing component to move to the gap between the porous member and the discharge port of the extruder, so that the blowing component introduces gas into the plurality of extrusion holes; under the action of the gas, the cable material blocked in the plurality of extrusion holes is blown out, thereby effectively preventing the plurality of extrusion holes on the porous member from being blocked, reducing the difficulty of cleaning the porous member; and the cable material after being blown out is also cut into granules under the action of the cutting mechanism, thereby reducing the waste of cable material.

[0016] 2. When the porous part is driven to retreat, the blowing assembly can be synchronously driven to connect to the extrusion holes, thereby reducing the power source and the driving time. In this application, after the cable granulation is completed, the first driving member is controlled to move, the first driving member drives the driving gear to rotate, the driving gear drives the rack to move, and the rack drives the porous part to move, so as to separate the porous part from the discharge port of the extruder; at the same time, the driving gear drives the threaded rod to move through the thread, and the threaded rod drives the blowing assembly to connect with multiple extrusion holes; then, air is introduced into the multiple extrusion holes through the blowing assembly, and the cable material remaining in the extrusion holes is blown out by air pressure, thereby achieving the cleaning of the extrusion holes on the porous part.

[0017] 3. The fan blades and the cutter rotate synchronously, thereby being able to reduce the power source while also cutting the remaining cable material into particles. In the present invention, the driving component drives the air cylinder to move so that one end of the air cylinder abuts against the porous member, thereby ensuring that the air cylinder is connected to the multiple extrusion holes; and after the air cylinder is connected to the multiple extrusion holes, the transmission unit connects the transmission shaft and the rotating shaft so that the transmission shaft and the rotating shaft rotate synchronously, and then the transmission shaft and the rotating shaft can be driven to rotate synchronously by the second driving member, and the transmission shaft drives the fan blades to rotate, thereby introducing air into the multiple extrusion holes to discharge the remaining cable material in the extrusion holes; and the rotating shaft drives the cutter to rotate, for this reason, after the fan blades clean out the cable materials in the multiple extrusion holes, the remaining cable materials can be cut into particles under the rotation of the cutter, thereby reducing the waste of cable materials.

[0018] 4. Since the air blowing assembly can introduce gas into the multiple extrusion holes, the porous part can be cleaned in time. Therefore, the length of the porous part can be set longer, which can leave more cooling time for the cable material. To this end, the coolant is transported into the heat dissipation pipe through the pump body, thereby accelerating the heat dissipation of the filamentary material in the porous part, thereby facilitating the subsequent cutting mechanism to cut the filamentary material into granules.

[0032] During specific implementation, the driving component 5 drives the blowing cylinder 41 to move so that one end of the blowing cylinder 41 abuts against the porous member 1, thereby ensuring that the blowing cylinder 41 is connected to the multiple extrusion holes 11; and after the blowing cylinder 41 is connected to the multiple extrusion holes 11, the transmission unit 6 connects the transmission shaft 42 and the rotating shaft 31 to make the transmission shaft 42 and the rotating shaft 31 rotate synchronously, and then the transmission shaft 42 and the rotating shaft 31 can be driven to rotate synchronously through the second driving member, and the transmission shaft 42 drives the fan blades 43 to rotate, and then air is introduced into the multiple extrusion holes 11 to discharge the cable material remaining in the extrusion holes 11; and the rotating shaft 31 drives the cutter 32 to rotate.

Furthermore, a pump is used to deliver coolant into the heat dissipation pipe, thereby accelerating the heat dissipation of the filamentary material within the porous member 1 and facilitating subsequent cutting of the filamentary material into granules by the cutting mechanism 3.
