Description
Technical Field
[0001] This utility model relates to the technical field of pelletizers, and in particular to an anti-sticking pelletizer. Background Technology
[0002] Underwater pelletizers are core equipment in the modern polymer granulation field. They cut and cool the high-temperature molten polymer in the extrusion die underwater, forming regular plastic pellets. During this process, the pellet-water mixture generated in the pelletizing chamber is transported, cooled, and separated through a circulating water pipeline. The stability and cleanliness of the circulating water system are crucial for the continuous operation of the entire production line and the quality of the final product.
[0003] Currently, existing technologies, such as those disclosed in Chinese Patent Publication No. CN207954386U, focus on extending the cooling path and time of the pellets by adding elevated water tanks and spiral lifting devices to address the problems of insufficient internal cooling and easy deformation of the pellets. However, such designs generally neglect the issue of impurity control in the circulating water system. In actual operation, various impurities often exist in the circulating water system, mainly including: plastic micro-shavings and trailing filaments generated during pelleting, metal particles generated by corrosion or wear of pipes and water pumps, and environmental dust from the cooling tower or makeup water.
[0004] Because existing circulating water pipelines lack effective online filtration devices, these impurities circulate throughout the system with the water flow, causing a series of problems: First, hard impurities easily clog the precision discharge holes on the die head, leading to uneven or interrupted discharge, requiring shutdown for cleaning, which seriously disrupts production continuity; second, impurities accelerate the wear of key components such as mechanical seals, shorten equipment lifespan, and increase maintenance costs; more insidiously, fine impurities may adhere to the surface of plastic granules, contaminating the product and affecting its purity and subsequent processing performance. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an anti-sticking pelletizer.
[0006] This utility model discloses an anti-sticking pelletizer, comprising a base frame, a support platform, a die head, a pelletizing chamber, a water inlet pipe, a water delivery pipe, and a drain pipe. The support platform is mounted on the top of the base frame, and the die head is mounted on the top of the base frame. The output end of the die head is connected to the pelletizing chamber. The output end of the water inlet pipe is connected to the bottom of the pelletizing chamber, and the input end of the drain pipe is connected to the top of the pelletizing chamber. The pelletizing assembly also includes a pelletizing component, a filtering component, and a locking component. The pelletizing component is mounted on the top of the support platform, and the filtering component is positioned between the water inlet pipe and the water delivery pipe. The pelletizing component is detachably fixed to the pelletizing chamber via the locking component. In use, the pelletizing component is operated to seal and lock the front end of the pelletizing chamber. The assembly locks and secures the pelletizing assembly and the die head. With the help of the water pump and water supply pipe, the cooling water is filtered through the filter assembly. Then, the cooling water enters the pelletizing chamber through the water inlet pipe. The pelletizing assembly is started, and the cooling water cools and shapes the raw material inside the die head while the pelletizing assembly pellets the cooled and shaped raw material. Afterward, the cooling water carries the raw material particles through the drain pipe to the centrifuge, where the cooling water and raw material particles are separated. The cooling water returns to the cold water tank for cooling and is then reused by the water pump. The filter assembly filters impurities from the cooling water to prevent impurities from entering the pelletizing chamber and affecting the pelletizing efficiency of the raw material, and to prevent the drain pipe from clogging.
[0007] Preferably, the pelletizing assembly includes a slide rail, a base, a sealing plate, a motor, a pelletizing head, and a servo electric cylinder.

The operator manipulates the servo electric cylinder to extend via a controller, causing the base to guide the pelletizing head into the pelletizing chamber under the guidance of the slide rail. Simultaneously, the sealing plate seals the front end of the pelletizing chamber. The motor is started via the controller, causing the pelletizing head to pelletize the cooled and shaped raw material entering the pelletizing chamber. The sealing plate, in conjunction with a locking assembly, improves the sealing of the front end of the pelletizing chamber, reducing material carry-over by the pelletizing head, drainage pipe blockage, and pellet clumping.
[0008] Preferably, the filter assembly includes a housing, a base plate, a filter cartridge, and bolts. The filter cartridge is detachably installed inside the housing. The base plate is sealed to the bottom of the housing by bolts. The top of the housing is connected to the output end of the water supply pipe, and the side wall of the housing is connected to the input end of the water inlet pipe. Cooling water enters the housing from top to bottom through the water supply pipe. The filter cartridge filters impurities in the cooling water. The filtered cooling water then enters the pelletizing chamber through the water inlet pipe. After a period of use, the operator releases the bolts from the base plate to remove the filter cartridge from the housing and cleans the impurities inside the filter cartridge, improving convenience.
[0009] Preferably, the locking assembly includes a shaft pin, a lead screw, a U-shaped clamping plate, and a wing nut. Two sets of lead screws are respectively hinged to the two ends of the sealing plate through a set of shaft pins.
