Description

Technical Field

[0001] This utility model belongs to the field of polymer material processing technology, specifically a cooling pelletizing device for polymer material processing. Background Technology

[0002] Polymer materials are materials whose main components are polymer compounds. They are formed by the polymerization of many small and simple molecules through chemical reactions.

[0003] To facilitate subsequent storage, transportation, and processing, polymer materials are usually granulated to make them easier to incorporate into various molding equipment for further processing. The polymer material is first extruded to obtain long strips, which are then cut into granules. After extrusion molding, the polymer material is in a high-temperature molten state with high viscosity and fluidity, requiring rapid solidification to improve hardness and rigidity, making it easier for cutting tools to make precise cuts.

[0004] Traditional methods for cooling polymer materials often involve introducing the polymer material into a water tank and immersing it in the water for a certain period of time. During use, as the cooling process continues, the water in the tank continuously absorbs heat from the polymer material, and the water temperature gradually rises. When the cooling water temperature rises to a certain level, the temperature difference between the cooling water and the polymer material decreases, which can easily lead to a reduction in heat exchange efficiency, a slower cooling rate, and the need for frequent drainage and water replenishment, increasing operating costs and water consumption.

[0005] Therefore, this utility model provides a cooling pelletizing device for processing polymer materials. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5As shown in the figure, a cooling and pelletizing device for processing polymer materials according to an embodiment of the present invention includes a workbench 1; two fixed frames 10 are fixedly connected to one end of the top of the workbench 1; two motors 11 are installed in one of the fixed frames 10; the output end of the motor 11 passes through the middle of the fixed frame 10; a conveying roller 12 is fixedly connected to the output end of the fixed frame 10; the end of the conveying roller 12 is rotatably connected to the middle of the other fixed frame 10; a cooling chamber 13, a drying chamber 14 and a pelletizing chamber 16 are fixedly connected to the top of the workbench 1; the top of the cooling chamber 13 and the drying chamber 14 are provided with a top cover 15; the middle of the cooling chamber 13 is rotatably connected to the conveying roller 12; the middle of the drying chamber 14 is rotatably connected to two conveying rollers 12; through grooves 111 are opened on the side walls of the cooling chamber 13, the drying chamber 14 and the pelletizing chamber 16; rollers 112 are rotatably connected to the bottom of the through grooves 111; a motor 11 is installed on the side wall of the pelletizing chamber 16; a pelletizing blade 17 is fixedly connected to the output end of the motor 11; a distance is provided between the pelletizing blade 17 and the pelletizing chamber 16. There is an installation component 5; the workbench 1 has an equipment slot 18 and a collection slot 19 in the middle; the equipment slot 18 has a cooling component 2 and an exhaust component 3 in the middle; the collection slot 19 has a collection box 100 installed in the middle; the cooling component 2 includes a water storage tank 21; the water storage tank 21 is fixedly connected to the middle of the equipment slot 18; the end of the water storage tank 21 is fixedly connected to a water inlet pipe 22; the bottom of the cooling chamber 13 is fixedly connected to a drain pipe 23; the end of the drain pipe 23 is fixedly connected to the top of the water storage tank 21; the side wall of the water storage tank 21 is installed with... A cooling tank 24 is provided; a first connecting pipe 25 is fixedly connected to the top of the cooling tank 24; a water pump 26 is fixedly connected to the end of the first connecting pipe 25; the water pump 26 is located on the top of the water storage tank 21; a second connecting pipe 27 is fixedly connected to the middle of the water pump 26; a water outlet pipe 28 is fixedly connected to the end of the second connecting pipe 27; the water outlet pipe 28 is U-shaped; the water outlet pipe 28 passes through the side wall of the cooling chamber 13; the end of the water outlet pipe 28 is fixedly connected to the inner side wall of the cooling chamber 13; two sets of nozzles 29 are fixedly connected to the middle of the water outlet pipe 28.During operation, multiple strips of polymer material can be placed between two external conveying rollers 12. The top cover 15 is opened, and the material passes through multiple channels 111 and the conveying rollers 12 into the pelletizing chamber 16, where the pelletizing blade 17 is located. Two motors 11 are controlled to rotate the two conveying rollers 12, transporting the material. Cooling water is discharged into the cooling chamber 13 via the cooling assembly 2. The material is cooled as it passes through the exhaust assembly 3. The cooled material then enters the drying chamber 14, where the exhaust assembly 3 vents airflow to dry the material. The motor 11 on the side wall of the pelletizing chamber 16 is opened, causing its output to drive the pelletizing blade 17 to rotate. The dried material is then cut into pellets by the pelletizing blade 17, which fall into the collection box 100 for collection. Cooling water is injected into the water storage tank 21 through the valve in the inlet pipe 22 for storage, and some of the cooling water is also stored in the storage tank 21. When the material is placed inside the cooling chamber 13, the water pump 26 is activated, and the water in the storage tank 21 is discharged through the cooling tank 24 to the second connecting pipe 27. It then exits through the outlet pipe 28 from multiple nozzles 29 and enters the cooling chamber 13. Simultaneously, the water in the cooling chamber 13 flows back into the storage tank 21 through the drain pipe 23. After the water in the storage tank 21 is cooled by the exhaust assembly 3, it re-enters the cooling tank 24, thus circulating the cooling water and maintaining the cooling temperature inside the conveying roller 12. This structure allows the polymer material to quickly reach the ideal cooling state, effectively improving the efficiency and speed of pelletizing. Furthermore, the circulating cooling water reduces waste caused by direct discharge of large amounts of water after cooling and maintains a relatively stable water temperature, ensuring uniform and stable cooling of the material and reducing product defects caused by uneven cooling.

[0025] like Figures 1 to 3As shown, the exhaust assembly 3 includes a heat pipe 31; the heat pipe 31 is installed on the outer wall of the water storage tank 21; two heat sinks 32 are installed in the middle of the heat pipe 31; a cooling fan 33 is installed in the middle of the heat sink 32; an air outlet pipe 34 is fixedly connected to the middle of the two cooling fans 33; an exhaust pipe 37 is fixedly connected to the middle of the air outlet pipe 34; two exhaust boxes 35 are fixedly connected to the inner wall of the drying chamber 14; the two exhaust boxes 35 are arranged opposite each other; several air outlet slots 36 are provided in the middle of the exhaust box 35; both ends of the exhaust pipe 37 are fixedly connected to the ends of the two exhaust boxes 35; the exhaust pipe 37 penetrates the side wall of the drying chamber 14; during operation, the cooling fans 33 are turned on, and the used water enters the water storage tank 21. After entering the interior, the heat inside the water storage tank 21 is conducted out through the heat pipe 31 and dissipated through the heat sink 32. The fan blades inside the air outlet duct 34 rotate at high speed, dissipating the heat into the air outlet duct 34. The airflow enters the air outlet box 35 through the air outlet duct 37 and blows the material dry through several air outlet slots 36. The dried material then enters the pelletizing chamber 16 for pelletizing. Through the above structure, the heat dissipated by the cooling water inside the water storage tank 21 is discharged to the surface of the material with the airflow, effectively accelerating the evaporation rate of the surface moisture of the cooled material. It can recover and utilize the waste heat generated during the cooling process and reduce the energy consumption of additional equipment.

[0026] like Figure 1 , Figure 2 , Figure 5 As shown, a driver 4 is installed on the side wall of the equipment tank 18; the output end of the driver 4 passes through the middle of the workbench 1; a rotating shaft 41 is fixedly connected to the output end of the driver 4; the end of the rotating shaft 41 is rotatably connected to the side wall of the collection tank 19; multiple levers 42 are fixedly connected to the middle of the rotating shaft 41; the multiple levers 42 are equidistantly distributed; multiple fixing plates 43 are fixedly connected to the inner side wall of the collection tank 19; a sliding rod 44 is slidably connected to the middle of the fixing plate 43; a sieve plate 45 is fixedly connected to the end of the sliding rod 44; two ball rods 46 are fixedly connected to the bottom of the sieve plate 45; during operation, after the polymer material is granulated by the pelletizing knife 17, the granulated material first falls to the middle of the sieve plate 45, controlling the driver 4 to open, so that the output end of the driver 4 drives the rotating shaft. 41 rotates at the bottom of the sieve plate 45. When the rotating shaft 41 rotates, multiple deflectors 42 deflect the end of the ball rod 46. After deflecting the ball rod 46, it moves upward with the deflectors 42. At this time, multiple sliding rods 44 slide upward in the middle of the fixed plate 43. When the ball rod 46 enters between two deflectors 42, the ball rod 46 falls down instantly, and the sliding rods 44 slide downward at the same time. When the rotating shaft 41 continues to rotate, the sieve plate 45 vibrates up and down. The vibration separates the sticky materials. The above structure can effectively separate the sticky particles after the material is granulated, effectively reduce the agglomeration of particles, maintain the uniformity of particles, and facilitate the subsequent packaging and transportation of the granulated material.

[0027] like Figure 5As shown, the mounting assembly 5 includes a threaded rod 51; the threaded rod 51 is threadedly connected to the side wall of the pelletizing chamber 16; mounting sleeves 53 are installed at both the end of the threaded rod 51 and the output end of the motor 11; a rotating block 52 is fixedly connected to the other end of the threaded rod 51; during operation, when the pelletizing blade 17 is installed inside the pelletizing chamber 16, first rotate the rotating block 52 to unscrew the threaded rod 51 from one side of the pelletizing chamber 16, insert one end of the pelletizing blade 17 into the mounting sleeve 53 at the end of the motor 11, and then align the other end of the pelletizing blade 17 with the mounting sleeve 53 at the end of the threaded rod 51. The rotating block 52 is rotated in the opposite direction to screw the threaded rod 51 into the pelletizing chamber 16. At this time, the mounting cylinder 53 at the end of the threaded rod 51 continues to approach the end of the pelletizing blade 17, allowing the end of the pelletizing blade 17 to enter, thereby installing the pelletizing blade 17. The above operation is repeated when disassembling. Through the above structure, the pelletizing blades 17 with different spacings can be replaced according to the pelletizing requirements, effectively adapting to different pelletizing requirements. It can realize the operation of quick maintenance of the pelletizing blade 17, and can quickly disassemble and clean and replace the pelletizing blade 17. The operation is convenient and quick.

[0028] like Figure 5 As shown, a rubber pad 6 is fixedly connected to the middle of the mounting cylinder 53; the rubber pad 6 is fixedly connected to the inner wall of the mounting cylinder 53; during operation, when the two ends of the pelletizer 17 are installed inside the two mounting cylinders 53, the ends of the pelletizer 17 contact the rubber pad 6 and squeeze the rubber pad 6, causing the rubber pad 6 to elastically contract. Through the above-mentioned structure, the interference fit between the rubber pad 6 and the end of the pelletizer 17 can fix the pelletizer 17, effectively reducing the sliding and friction of the end of the pelletizer 17 in the middle of the mounting cylinder 53, and effectively reducing the wear of the end of the pelletizer 17.

[0029] like Figure 5 As shown, the surface of the pelletizing blade 17 is provided with an anti-stick coating. During operation, when the pelletizing blade 17 is cutting the material into pellets, the low surface energy characteristics of the coating material are used to prevent direct contact between the polymer material and the blade of the pelletizing blade 17. Through the above structure, the adhesion of the polymer material to the pelletizing blade 17 during pelletizing can be effectively reduced, the frequency of cleaning the surface of the pelletizing blade 17 can be effectively reduced, the pelletizing blade 17 can be operated continuously, and the production efficiency of material pelletizing can be effectively increased.

[0030] During operation, multiple strips of polymer material can be placed between two external conveying rollers 12. The top cover 15 is opened, and the material passes through multiple channels 111 and the conveying rollers 12 into the pelletizing chamber 16, where the pelletizer 17 is positioned. Two motors 11 are controlled to rotate the two conveying rollers 12, transporting the material. Cooling water is discharged into the cooling chamber 13 via the cooling assembly 2. The material is cooled as it passes through the exhaust assembly 3. The cooled material then enters the drying chamber 14, where the exhaust assembly 3 vents airflow to dry the material. The motor 11 on the side wall of the pelletizing chamber 16 is turned on, causing its output to drive the pelletizer 17 to rotate. The dried material is then cut into pellets by the pelletizer 17. Granulated material falls into the collection box 100 for collection. Cooling water is injected into the storage tank 21 through the valve in the inlet pipe 22 for storage, and some cooling water is placed into the cooling chamber 13. When cooling the material, the water pump 26 is turned on, and the water in the storage tank 21 is discharged into the second connecting pipe 27 through the cooling tank 24, and then discharged from multiple nozzles 29 through the outlet pipe 28 into the cooling chamber 13. The water in the cooling chamber 13 simultaneously flows back into the storage tank 21 through the drain pipe 23. After the water in the storage tank 21 is cooled by the exhaust assembly 3, it enters the cooling tank 24 again, thus circulating the cooling water to maintain the cooling temperature inside the conveyor roller 12. The cooling fan 33 is turned on for use. After the water enters the water storage tank 21, the heat inside the water storage tank 21 is conducted out through the heat conduction pipe 31 and dissipated through the heat sink 32. The fan blades inside the air outlet duct 34 rotate at high speed, exhausting the heat into the air outlet duct 34. The airflow enters the air outlet box 35 through the air outlet duct 37 and blows the material dry through several air outlet slots 36. The dried material then enters the pelletizing chamber 16 for pelletizing. After the polymer material is pelletized by the pelletizing knife 17, the pelletized material first falls to the middle of the screen plate 45. The control driver 4 is turned on, so that the output end of the driver 4 drives the rotating shaft 41 to rotate at the bottom of the screen plate 45. When the rotating shaft 41 rotates, multiple deflectors 42 actuate the end of the ball rod 46. After the ball rod 46 is actuated, it moves upward with the deflectors 42. Multiple sliding rods 44 slide upwards in the middle of the fixed plate 43, causing the ball rod 46 to enter between the two deflector plates 42. The ball rod 46 then falls instantly, and the sliding rods 44 slide downwards simultaneously. As the rotating shaft 41 continues to rotate, the screen plate 45 vibrates up and down, separating the adhesive materials through vibration. When installing the pelletizing knife 17 inside the pelletizing chamber 16, first rotate the rotating block 52 to unscrew the threaded rod 51 from one side of the pelletizing chamber 16. Insert one end of the pelletizing knife 17 into the mounting cylinder 53 at the end of the motor 11. Then, align the other end of the pelletizing knife 17 with the mounting cylinder 53 at the end of the threaded rod 51. Rotate the rotating block 52 in the opposite direction to screw the threaded rod 51 into the pelletizing chamber 16. At this time, the mounting cylinder 53 at the end of the threaded rod 51 continues to approach the end of the pelletizing knife 17, allowing the end of the pelletizing knife 17 to enter.This allows the pelletizer 17 to be installed. Disassembly is performed by repeating the above steps. When the pelletizer 17 is installed inside the two mounting cylinders 53, the ends of the pelletizer 17 contact the rubber pad 6 and compress it, causing the rubber pad 6 to elastically contract. During the pelletizing process, the low surface energy of the coating material prevents direct contact between the polymer / material and the pelletizer 17 blade.
