Description

Technical Field

[0001] The invention relates to the technical field of pelletizing for manufacturing shielding materials, in particular to a pelletizing device for manufacturing cable shielding materials. Background Art

[0002] Pelletizing for shielding material manufacturing is a process specifically used for the production of cable shielding materials. The extruded molten shielding material is cut through a specific pelletizing system to form uniform, round particles to ensure the quality and performance of the cable shielding layer. This process not only improves production efficiency, but also reduces manual labor through automated control, and avoids the generation of debris through underwater or cold cutting techniques, keeps the working environment clean, and improves the product's appearance quality and production efficiency. The existing Chinese patent with publication number CN220923239U discloses a black masterbatch pelletizing device, including an operating table, a fixed block is fixedly connected to the upper left surface of the operating table, an extruder is fixedly connected to the upper surface of the fixed block, and an observation window is opened on the upper surface of the extruder; scale lines are set on the outer surface of the observation window, a pneumatic cylinder is fixedly connected to the left inner wall of the extruder, and a pneumatic rod is movably connected to the outer surface of the pneumatic cylinder. The black masterbatch pelletizing device is provided with an operating table, an extruder, an observation window, a scale line, a pneumatic cylinder, a pneumatic rod and an extrusion plate. The fixing block on the operating table helps to fix the extruder stably and firmly. The pneumatic cylinder drives the extrusion plate on the pneumatic rod to telescope and move in the extruder to extrude, so that the masterbatch is extruded and cut into masterbatch. However, the operator can control the telescopic movement distance of the pneumatic cylinder through the scale line on the observation window to flexibly adjust the length of the extruded masterbatch and increase the adjustment flexibility of the device. However, the existing pelletizing device directly collects the particles after pelletizing. However, when pelletizing, the inconsistency of the extrusion speed, cooling rate, cutting frequency and other factors of the material makes the produced particles inconsistent in size, resulting in particles of different sizes being mixed together, making the screening of particles more complicated and time-consuming, and reducing the collection efficiency.

[0030] Working principle: When it is necessary to produce particles, the raw materials after hot melting are poured into the conveying cylinder 22. Since the inner wall of the conveying cylinder 22 is provided with multiple groups of heating grooves 221, the raw materials can be further mixed and stirred during the conveying process, and the raw materials can be kept in the form of fluid for conveying. When the raw materials reach one end of the extrusion tube 225, the raw materials will be squeezed out by the screw rod 24, and the cooling water in the cooling groove 224 will solidify it. Since the water pump 262 keeps adding the cooling water in the water tank 26 to the cooling groove 224, the water in the cooling groove 224 will enter the circulation pipe 263 and finally return to the water tank 26, so that the inside of the cooling groove 224 is always at the same temperature to solidify the raw materials. When solidified When the raw material passes through the other end of the extrusion tube 225, the rotating cutter 37 will cut the solidified raw material, thereby cutting the raw material into particles. Just before the raw material is added, the T-block 515 can be pressed at the same time to allow the slope C5151 to move along the slope B5144, thereby lowering the movable block 5143, and the L-tube 52 on the lower surface of the slope B5144 will bring the rectangular plate 53 down together, allowing the cylinder 55 to break away from the rod groove 417 on the lower surface of the slider 414, and then the cross plate 51 can be pulled or pushed to allow the adjustment plate 413 to move horizontally inside the plate groove A411, thereby selecting a pipe with a qualified particle size and caliber. When the caliber selection is completed, release the T-block 515 to allow the slope B5144 to move in. The cylinder 55 is re-inserted into the rod groove 417, and the adjusting plate 413 is fixed. Then, as the raw materials are cut, the particles will be adjusted to pass through the discharge port 11 and fall onto the surface of the screening plate 41. Since one side of the screening plate 41 is connected to the movable plate 44, and the upper end of the movable plate 44 is inside the sleeve ring 35, when the turntable 34 rotates to cut the raw materials, the arc plate 38 on the outer surface of the turntable 34 will continuously hit the upper surface of the movable plate 44, so that the movable plate 44 moves downward, and the springs B46 on both sides of the movable plate 44 will make the movable plate 44 bounce back to the inside of the turntable 34 when it is hit and dropped, so that the movable plate 44 is always in a state of moving up and down. As the movable plate 44 rises and falls, the screening plate 41 will also move along with it. The side rods 42 on both sides of 41 are rotatably connected to the inner wall of the screening slot 14, so the screening plate 41 can only rotate, and the particles with qualified calibers on the surface of the screening plate 41 will pass through the cone mouth 412 and directly fall into the collecting frame 19, while the unqualified particles will vibrate continuously on the surface of the screening plate 41 along the screening plate 41 and the arc plate 47. When the screening plate 41 flips and reaches the start time point preset by the motor 472, the motor 472 will rotate the cross rod 473 and flip the flip plate 474, so that the unqualified particles on the surface of the screening plate 41 are discharged from the other end of the screening slot 14. When the screening plate 41 is constantly flipping, the long plates 48 on both sides of the screening plate 41 will constantly squeeze the hand blower 49, causing the hand blower 49 to blow air continuously.When the long plate 48 begins to squeeze the hand blower 49, it means that the screening plate 41 has tilted. Since the outer surface of the air outlet pipe at one end of the hand blower 49 is matched with the inner wall of the air groove 4131, when the air outlet pipe of the hand blower 49 contacts one end of the air groove 4131, the air outlet pipe of the hand blower 49 will enter the interior of one end of the air groove 4131 and start to inflate the inside of the adjustment plate 413. The airflow entering the adjustment plate 413 will flow inside each air groove 4131, the small-diameter pipe 4132, and the large-diameter pipe 4133, which can not only prevent larger particles from being blocked, but also speed up the flow of particles, thereby achieving the effect of effective screening when producing particles.
