Abstract
Description
Technical Field
[0001] This utility model relates to the field of color masterbatch processing technology, specifically a pelletizer for color masterbatch processing. Background Technology
[0002] Color masterbatch is a polymeric colorant, typically a granular composite made from pigments or dyes, carrier resins, dispersants, and other functional additives through specific processes. Its core function is to provide stable and uniform color to polymeric materials such as plastics and rubber. In color masterbatch production, the pelletizer is a key piece of equipment, usually linked with an extruder to form an automated "mixing-extrusion-pelletizing" production line. This not only enables continuous batch production, significantly improving efficiency, but also further refines the particles, preventing color differences or spots in colored products. It also prevents moisture absorption and clumping during storage and transportation, and avoids environmental pollution and health hazards caused by dust.
[0003] According to a search, Chinese patent document CN219235804U discloses a pelletizer for processing color masterbatch. This pelletizer, through a set of slide rails, a movable frame, a sieve plate, a round rod, a second spring, rollers, a second servo motor, a cam, and a collection assembly, can screen color masterbatch, automatically removing larger pieces, making screening easier, improving masterbatch quality, eliminating the inconvenience of manual screening, increasing work efficiency, and facilitating widespread use. However, in actual use, when the material strips enter the pelletizer, their surface temperature may still be slightly high or contain trace amounts of incompletely solidified low-melting-point components, easily causing slight adhesion to the metal roller surface, leading to surface damage and affecting the regularity of subsequent cutting. Furthermore, the device directly pours the material strips into the feed pipe without corresponding guiding and traction devices, thus significantly impacting the smooth conveying of the material strips and the final pellet quality; there is still room for optimization in traction synchronization. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a pelletizer for color masterbatch processing, which has the advantages of reasonable structure, convenient operation, effective cooling to prevent sticking, and high cutting quality, thus solving the above-mentioned technical problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a pelletizer for color masterbatch processing, comprising a side platform, a guide roller installed inside the side platform, a support and a pelletizing box fixedly installed on the top surface of the side platform, a water spray pipe fixedly installed on the bottom surface of the support, a nozzle fixedly installed at the bottom end of the water spray pipe, an inlet pipe fixedly connected to the outer side of the water spray pipe, a first motor fixedly installed on the front side of the pelletizing box, a second motor fixedly installed on the left side of the pelletizing box, a feed inlet opened on the right side of the pelletizing box, a cylinder fixedly installed on the top surface of the pelletizing box, a base and a funnel fixedly installed inside the pelletizing box, a first traction roller installed inside the base, a limit slide rail fixedly installed on the top surface of the base, a slider slidably installed inside the limit slide rail, and a second traction roller installed on the inner side of the slider.
[0008] Preferably, there are two bases, the output shaft of the first motor is fixedly connected to the front end of the first traction roller, and the output shaft of the second motor is fixedly connected to a cutting blade.
[0009] With the above technical solution, after the material strip is extruded by the extruder, it is placed between the first traction roller and the second traction roller. Then, when the first motor is started, the output shaft of the first motor can drive the first traction roller to rotate. The first traction roller, together with the second traction roller, can drive the material strip to move. At the same time, the second motor is started, and the output shaft of the second motor can drive the cutting blade to rotate. The cutting blade can then effectively cut the material strip into granules and drop them into the inside of the funnel, improving the stability of the device's conveying and the overall quality of the granules.
[0010] Preferably, there are two side platforms and multiple guide rollers, and each of the multiple guide rollers has a guide groove on its outer side surface.
[0011] With the above technical solution, when the material strip is placed between the first traction roller and the second traction roller, it is also placed inside multiple guide grooves. Therefore, when the material strip is moving, the multiple guide grooves can effectively limit its position, prevent multiple material strips from getting entangled, and improve the overall stability of the device.
[0012] Preferably, there are multiple of the support, the water spray pipe, and the nozzle.
[0013] The above technical solution connects the water inlet pipe to external water pumps and other equipment. The water pumps can deliver water to the inside of multiple spray pipes, and then spray it down through the nozzles. This effectively cools and de-temperatures the material strips, preventing adhesion or damage during subsequent traction or cutting, thus ensuring the normal operation of the device and the final quality of the product.
[0014] Preferably, there are two cylinders, two limit slide rails, and two sliders, and the output shafts of the two cylinders are fixedly connected to the top surfaces of the two sliders.
[0015] With the above technical solution, when the two cylinders are started, the output shaft of the cylinders can drive the slider and the second traction roller to move in the vertical direction, thereby effectively adjusting the distance between them and the first traction roller. This makes it suitable for material strips of different diameters and improves the overall practicality of the device.
[0016] Preferably, a collection box is provided on the bottom surface of both the funnel and the nozzle.
[0017] With the above technical solution, after the material strip is cut, it can fall from the funnel into the inside of the collection box to complete the collection; in addition, when water is sprayed from the nozzle to cool the material strip, the water will fall directly into the inside of the collection box to complete the collection, which is convenient for workers to carry out subsequent processing and resource recycling.
[0018] Compared with the prior art, this utility model provides a pelletizer for color masterbatch processing, which has the following beneficial effects:
[0019] 1. This utility model utilizes two cylinders. The output shafts of the cylinders drive the slider and the second traction roller to move vertically, effectively adjusting the distance between them and the first traction roller, thus adapting to material strips of different diameters. After the material strip is extruded through the extruder, it is placed between the first and second traction rollers, and the first and second motors are activated. The output shaft of the first motor drives the first traction roller to rotate, and the first and second traction rollers work together to move the material strip. Meanwhile, the output shaft of the second motor drives the cutting blade to rotate, effectively cutting the material strip into granules that fall into the hopper, improving the stability of the conveying process and the overall quality of the granules.
[0020] 2. This utility model connects the water inlet pipe to an external water pump and other equipment. The water pump can deliver water to the inside of multiple spray pipes, and then spray it down through the nozzles. This can effectively cool and reduce the temperature of the material strip, preventing adhesion and damage during subsequent traction or cutting, thus ensuring the normal operation of the device and the final quality of the product.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-4 A pelletizer for processing masterbatch includes a side platform 1, a guide roller 2 installed inside the side platform 1, a support 3 and a pelletizing box 4 fixedly installed on the top surface of the side platform 1, a water spray pipe 5 fixedly installed on the bottom surface of the support 3, a nozzle 6 fixedly installed at the bottom end of the water spray pipe 5, and a water inlet pipe 7 fixedly connected to the outer side of the water spray pipe 5. A first motor 8 is fixedly installed on the front side of the pelletizing box 4, a second motor 9 is fixedly installed on the left side of the pelletizing box 4, a feed inlet 10 is opened on the right side of the pelletizing box 4, a cylinder 11 is fixedly installed on the top surface of the pelletizing box 4, a base 12 and a funnel 13 are fixedly installed inside the pelletizing box 4, a first traction roller 14 is installed inside the base 12, a limit slide rail 15 is fixedly installed on the top surface of the base 12, a slider 16 is slidably installed inside the limit slide rail 15, and a second traction roller 17 is installed on the inner side of the slider 16.
[0028] Specifically, there are two bases 12. The output shaft of the first motor 8 is fixedly connected to the front end of the first traction roller 14, and the output shaft of the second motor 9 is fixedly connected to the cutting blade 18. The advantage is that, with this structure, after the material strip is extruded through the extruder, it is placed between the first traction roller 14 and the second traction roller 17. When the first motor 8 is started, its output shaft drives the first traction roller 14 to rotate, and the first traction roller 14, in conjunction with the second traction roller 17, moves the material strip. Simultaneously, the second motor 9 is started, and its output shaft drives the cutting blade 18 to rotate. The cutting blade 18 effectively cuts the material strip into granules, which fall into the hopper 13, improving the stability of the conveying process and the overall quality of the granules.
[0029] Specifically, there are two side platforms 1 and multiple guide rollers 2, with guide grooves 19 formed on the outer surfaces of each guide roller 2. The advantage is that this structure allows the material strip to be placed both between the first traction roller 14 and the second traction roller 17 and simultaneously within the multiple guide grooves 19. Therefore, when the material strip moves, the multiple guide grooves 19 effectively restrict its position, preventing the multiple material strips from tangling and improving the overall stability of the device.
[0030] Specifically, multiple supports 3, water spray pipes 5, and nozzles 6 are provided. The advantage is that this structure connects the water inlet pipe 7 to external equipment such as water pumps. The water pumps can deliver water to the interior of multiple water spray pipes 5, and then spray it through the nozzles 6. This effectively cools and de-temperatures the material strip, preventing adhesion and damage during subsequent traction or cutting, thus ensuring the normal operation of the device and the final quality of the product.
[0031] Specifically, there are two cylinders 11, two limit rails 15, and two sliders 16, and the output shafts of the two cylinders 11 are fixedly connected to the top surfaces of the two sliders 16. The advantage is that, with this structure, when the two cylinders 11 are activated, the output shafts of the cylinders 11 can drive the sliders 16 and the second traction roller 17 to move vertically, thereby effectively adjusting the distance between them and the first traction roller 14. This allows the device to be used with material strips of different diameters, improving the overall practicality of the device.
[0032] Specifically, both the bottom surfaces of the funnel 13 and the nozzle 6 are equipped with collection boxes 20. The advantage is that, with this structure, when the material strip is cut, it can fall from the funnel 13 into the collection box 20, thus completing the collection; in addition, when water is sprayed from the nozzle 6 to cool the material strip, the water will fall directly into the collection box 20 for collection, which facilitates subsequent processing and resource recycling by the staff.
[0033] In operation, by activating the two cylinders 11, the output shafts of the cylinders 11 can drive the slider 16 and the second traction roller 17 to move vertically, thereby effectively adjusting the distance between them and the first traction roller 14, making it suitable for material strips of different diameters. After the material strip is extruded through the extruder, it is placed between the first traction roller 14 and the second traction roller 17, and the first motor 8 and the second motor 9 are activated. The output shaft of the first motor 8 drives the first traction roller 14 to rotate, and the first traction roller 14, in conjunction with the second traction roller 17, can move the material strip. The material strip moves, and the output shaft of the second motor 9 drives the cutting blade 18 to rotate. The cutting blade 18 can effectively cut the material strip into granules and drop them into the funnel 13, improving the stability of the device's conveying and the overall quality of the granules. By connecting the water inlet pipe 7 to external water pumps and other equipment, the water pump can deliver water to the inside of multiple water spray pipes 5, and then spray it through the nozzles 6, which can effectively cool the material strip and prevent adhesion or damage during subsequent traction or cutting, ensuring the normal operation of the device and the final quality of the product.
