Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic masterbatch production equipment, and in particular to a plastic masterbatch pelletizer that can continuously cut in a cyclic manner. Background Technology
[0002] Primarily used for crushing plastic raw materials into small particles for subsequent processing and handling, plastic masterbatch pelletizers have wide applications in the plastics processing industry. These particles can be used in plastic modification, plastic dyeing, and plastic recycling. The pelletizer's structure mainly includes a motor, reducer, pelletizing blades, feed inlet, and discharge outlet. The motor drives the reducer, causing the pelletizing blades to rotate at high speed, thereby crushing the plastic raw materials into small particles.
[0003] In the prior art, such as the Chinese patent publication number CN220280161U, which discloses a continuous cutting plastic masterbatch pelletizer, belonging to the technical field of plastic masterbatch production equipment, the invention includes a housing. The housing is equipped with a material screening device for screening the cut plastic. The housing also includes a cutting assembly for cutting the plastic and facilitating the replacement of damaged parts. Furthermore, the housing is equipped with an adaptive lighting device for providing illumination during inspection and maintenance of the continuous cutting plastic masterbatch pelletizer. Finally, the housing is equipped with a feeding device for transporting the plastic to be cut to the continuous cutting plastic masterbatch pelletizer. Through these methods, the present invention uses a material screening device to screen the cut plastic masterbatch. When the blade is damaged, only the blade needs to be replaced, rather than replacing the entire cutting tool, saving costs. The adaptive lighting device provides illumination during the inspection and maintenance of the entire continuous cutting plastic masterbatch pelletizer.
[0004] In actual production, although this type of plastic masterbatch pelletizer can also cut plastic, the gap of the feeding device is too large when cutting plastic. This may result in an excessively large movement distance of the plastic before it is cut by the blade, which may cause the cut plastic masterbatch to be of different sizes, thus affecting the quality of the plastic masterbatch and leading to poor performance of the device. Therefore, it needs to be improved. Utility Model Content
[0005] The purpose of this invention is to provide a plastic masterbatch pelletizer that can continuously cut plastics, which has a good effect on continuous cutting of plastics.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a continuously circulating plastic masterbatch pelletizer, comprising a machine tool, a support leg fixedly connected to the bottom of the machine tool, a square hole opened inside the machine tool, an extrusion tube fixedly connected to the upper surface of the machine tool, a feed hopper provided outside the machine tool, the feed hopper penetrating into the interior of the extrusion tube, a hydraulic press fixedly connected to the upper surface of the machine tool, a pusher plate provided inside the extrusion tube, a circular hole opened inside the extrusion tube, the output end of the hydraulic press penetrating into the circular hole and fixedly connected to the pusher plate, and a circular sleeve provided outside the machine tool. One end of the tube extends into the interior of the circular casing. The extrusion tube has a small extrusion hole inside. A base is fixedly connected to the upper surface of the machine tool, and a motor is fixedly connected to the upper surface of the base. A cutting blade is installed inside the circular casing, and a rotating hole is opened inside the circular casing. The output end of the motor extends into the rotating hole and is fixedly connected to the cutting blade. A discharge pipe is installed outside the circular casing. An inclined screen is fixedly connected to the bottom of the machine tool, and a water tank is installed at the bottom of the inclined screen. A through pipe is installed outside the extrusion tube, and a circulation pipe is installed outside the inclined screen. A pump box is fixedly connected to the outside of the machine tool.
[0007] By adopting the above technical solution, workers feed heated, gel-like plastic into the extrusion tube through the feed hopper. Simultaneously, the hydraulic press and motor are started. The motor's output drives the cutting blade to rotate at high speed inside the circular housing, while the hydraulic press's output drives the pusher plate, which pushes the gel-like plastic inside the extrusion tube. When the plastic contacts the extrusion orifice, the pusher plate's thrust forces the plastic to be evenly extruded from the orifice, forming strips of uniform diameter. These strips immediately contact the high-speed rotating cutting blade and are cut into plastic granules. The granules fall through the discharge pipe onto the upper surface of the inclined screen. The continuous rotation of the cutting blade continuously cuts the gel-like plastic into granules, achieving excellent continuous cutting results for the plastic.
[0008] A further feature of this invention is that an anti-stick coating is fixedly connected to the upper surface of the push plate, and the anti-stick coating is made of Teflon.
[0009] By adopting the above technical solution, the Teflon non-stick coating prevents the adhesive plastic from sticking to the upper surface of the push plate.
[0010] A further feature of this invention is that a buffer spring is fixedly connected inside the base, and the spacing between each pair of buffer springs is equal.
[0011] By adopting the above technical solution, the motor will generate vibration force when it is working, and the buffer spring will make the base buffer the vibration force.
[0012] A further feature of this invention is that: a pump is fixedly connected inside the pump box; one end of the through pipe extends into the inside of the pump box; the other end of the through pipe extends into the inside of the circular sleeve; one end of the circulation pipe extends into the inside of the pump box; and the other end of the circulation pipe extends into the inside of the water tank.
[0013] By adopting the above technical solution, when cutting inside the circular casing, the pump is started and the water in the pool flows into the interior of the circular casing through the circulation pipe and the through pipe, so that the water cools and cleans the cut plastic particles.
[0014] A further feature of this invention is that an arc-shaped water-shielding plate is fixedly connected inside the circular box, and the number of the arc-shaped water-shielding plates is two.
[0015] By adopting the above technical solution, the two arc-shaped water shields block most of the water, preventing a large amount of water from flowing from the rotating hole to the motor.
[0016] A further feature of this invention is that a support rod is provided on the outside of the pump box, one end of the support rod is fixedly connected to the machine tool, and the other end of the support rod is fixedly connected to the through pipe.
[0017] By adopting the above technical solution, the struts provide support for the pipe.
[0018] A further feature of this invention is that a filter screen layer is fixedly connected inside the pump box, and the number of filter screen layers is two.
[0019] By adopting the above technical solution, the two filter layers filter out the foam in the water after washing plastic particles, thus protecting the pump.
[0020] A further feature of this invention is that a baffle is fixedly connected to the outside of the inclined screen, and a collection box is provided at the bottom of the machine tool.
[0021] By adopting the above technical solution, the falling plastic particles from the baffle are prevented, and the collection box facilitates the collection of plastic particles.
[0022] A further feature of this invention is that a fan bracket is fixedly connected to the outside of the machine tool, and a fan is fixedly connected to the outside of the fan bracket.
[0023] By adopting the above technical solution, the fan is turned on, and the fan blows air onto the plastic particles that fall onto the surface of the inclined screen, thus speeding up their drying process.
[0024] A further feature of this invention is that an arc-shaped hanging frame is fixedly connected to the outside of the water tank, and a wooden rake is provided on the upper surface of the arc-shaped hanging frame.
[0025] By adopting the above technical solution, plastic particles falling from the upper surface of the inclined screen are collected into the inside of the collection box by the air-drying household using a wooden rake.
[0026] The beneficial effects of this utility model are:
[0027] 1. This utility model, through the arrangement of a machine tool, support legs, square hole, extrusion tube, feed hopper, hydraulic press, push plate, round hole, circular sleeve, small extrusion hole, base, motor, cutting blade, rotating hole, discharge pipe, inclined screen, water tank, connecting pipe, circulation pipe, and pump box, allows workers to feed heated gelatinous plastic into the extrusion tube through the feed hopper. Simultaneously, the hydraulic press and motor are started. The motor's output drives the cutting blade to rotate at high speed inside the circular sleeve, while the hydraulic press's output drives the push plate, causing the push plate to push the gelatinous plastic... The material moves inside the extrusion tube. When the gel-like plastic comes into contact with the extrusion orifice, the pushing force generated by the pusher plate causes the gel-like plastic to be evenly extruded from the extrusion orifice, thus forming strips of plastic with the same diameter. As soon as the plastic strip is extruded from the extrusion orifice, it comes into contact with the high-speed rotating cutting blade and is then cut into plastic granules. The plastic granules fall onto the upper surface of the inclined screen through the discharge pipe. Through the continuous rotation of the cutting blade, the gel-like plastic is continuously cut into plastic granules. The above operation achieves a good effect of continuous cutting of plastic.
[0028] 2. This utility model, through the arrangement of an anti-stick coating, a buffer spring, a pump, an arc-shaped water shield, a support rod, a filter layer, a baffle, a collection box, a fan bracket, a fan, an arc-shaped hanger, and a wooden rake, utilizes a Teflon anti-stick coating to prevent the adhesive plastic from sticking to the upper surface of the push plate. When the motor operates, it generates vibration, and the buffer spring cushions this vibration. During cutting within the circular housing, starting the pump allows water from the pool to flow through the circulation pipe and connecting pipe into the circular housing, thus water-cooling the cut plastic particles. The cleaning process involves two curved baffles that block most of the water, preventing large amounts of water from flowing from the rotating hole to the motor. A support rod supports the pipe. Two layers of filter screens remove foam from the water after cleaning plastic particles, protecting the pump and preventing plastic particles from falling off the baffles. The collection box facilitates the collection of plastic particles. Turning on the fan blows air onto the surface of the inclined screen, accelerating the drying process. After drying, the plastic particles falling from the upper surface of the inclined screen are gathered into the collection box using a wooden rake. Attached Figure Description

[0036] Reference Figure 1-4A continuously recyclable plastic masterbatch pelletizing machine includes a machine tool 1, with support legs 2 fixedly connected to the bottom of the machine tool 1.

A feed hopper 5 is provided outside the machine tool 1, extending into the interior of the extrusion tube 4. A hydraulic press 6 is fixedly connected to the upper surface of the machine tool 1. A pusher plate 7 is provided inside the extrusion tube 4, with a circular hole 8 formed inside the extrusion tube 4. The output end of the hydraulic press 6 extends into the circular hole 8 and is fixedly connected to the pusher plate 7. A circular casing 9 is provided outside the machine tool 1, with one end of the extrusion tube 4 extending into the circular casing 9. An extrusion hole 10 is formed inside the extrusion tube 4. A base 11 is fixedly connected to the upper surface of the machine tool 1. A motor 12 is fixedly connected to the upper surface. A cutting blade 13 is installed inside the circular housing 9. A rotating hole 14 is opened inside the circular housing 9. The output end of the motor 12 passes through the rotating hole 14 and is fixedly connected to the cutting blade 13. A discharge pipe 15 is installed outside the circular housing 9. An inclined screen 16 is fixedly connected to the bottom of the machine tool 1. A water tank 17 is installed at the bottom of the inclined screen 16. A through pipe 18 is installed outside the extrusion pipe 4. A circulation pipe 19 is installed outside the inclined screen 16. A pump box 20 is fixedly connected to the outside of the machine tool 1. The worker puts the heated gel-like plastic into the extrusion pipe 4 through the feed hopper 5. Then, the hydraulic press 6 and the motor 12 are started at the same time. The hydraulic press 6 and the motor 12 start working. The output end of the motor 12 The cutting blade 13 rotates at high speed inside the circular housing 9. The output end of the hydraulic press 6 drives the pusher plate 7 to move, causing the pusher plate 7 to push the gel-like plastic inside the extrusion tube 4. When the gel-like plastic comes into contact with the extrusion orifice 10, the pushing force generated by the pusher plate 7 causes the gel-like plastic to be evenly extruded from the extrusion orifice 10, thus forming strips of plastic with the same diameter. As soon as the plastic strips are extruded from the extrusion orifice 10, they come into contact with the high-speed rotating cutting blade 13 and are then cut into plastic granules. The plastic granules fall onto the upper surface of the inclined screen 16 through the discharge pipe 15. Through the continuous rotation of the cutting blade 13, the gel-like plastic is continuously cut into plastic granules. Through the above operation, continuous cutting of plastic is achieved. For optimal cutting results, the upper surface of the push plate 7 is fixedly coated with an anti-stick coating 21 made of Teflon. This Teflon coating prevents adhesive plastic from sticking to the upper surface of the push plate 7. A buffer spring 22 is fixedly connected inside the base 11, with equal spacing between each spring. When the motor 12 operates, it generates vibration, and the buffer spring 22 cushions this vibration. A pump 23 is fixedly connected inside the pump box 20. One end of the connecting pipe 18 extends into the pump box 20, and the other end extends into the circular sleeve 9. One end of the circulation pipe 19 extends into the pump box 20, and the other end extends into the water tank 17. During cutting within the circular sleeve 9...After starting pump 23, water from pool 17 flows through circulation pipe 19 and through pipe 18 into the interior of circular housing 9, where the water cools and cleans the cut plastic particles. Two arc-shaped water-blocking plates 24 are fixedly connected inside circular housing 9, blocking most of the water and preventing a large amount of water from flowing from rotating hole 14 to motor 12. A support rod 25 is installed outside pump housing 20, with one end fixedly connected to machine tool 1 and the other end fixedly connected to through pipe 18, providing support for through pipe 18. Two filter layers 26 are fixedly connected inside pump housing 20, filtering out the plastic particles after cleaning. The foam in the water protects pump 23. A baffle 27 is fixedly connected to the outside of the inclined screen 16. A collection box 28 is installed at the bottom of machine tool 1 to prevent plastic particles from falling off the baffle 27. The collection box 28 facilitates the collection of plastic particles. A fan bracket 29 is fixedly connected to the outside of machine tool 1, and a fan 30 is fixedly connected to the outside of the fan bracket 29. When the fan 30 is turned on, it blows air onto the plastic particles falling onto the upper surface of the inclined screen 16, accelerating their drying. An arc-shaped hanger 31 is fixedly connected to the outside of the water tank 17. A wooden rake 32 is installed on the upper surface of the arc-shaped hanger 31. Plastic particles falling onto the upper surface of the inclined screen 16 are collected into the collection box 28 by the wooden rake 32 after drying.
[0037] In this invention, the worker feeds heated gel-like plastic into the extrusion tube 4 through the feed hopper 5. Simultaneously, the hydraulic press 6 and motor 12 are started. The output of the motor 12 drives the cutting blade 13 to rotate at high speed inside the circular housing 9. The output of the hydraulic press 6 drives the pusher plate 7, which pushes the gel-like plastic inside the extrusion tube 4. When the gel-like plastic contacts the extrusion orifice 10, the pushing force generated by the pusher plate 7 causes the plastic to be evenly extruded from the orifice 10, forming strips of plastic with the same diameter. The plastic strips contact the high-speed rotating cutting blade 13 as soon as they are extruded from the orifice 10 and are then cut into plastic granules. These granules fall through the discharge pipe 15 onto the upper surface of the inclined screen 16. The continuous rotation of the cutting blade 13 continuously cuts the gel-like plastic into plastic granules. This operation achieves excellent continuous cutting results for plastic. The anti-stick coating 21 made of dragon material prevents the adhesive plastic from sticking to the upper surface of the push plate 7. When the motor 12 is working, it will generate vibration. The buffer spring 22 makes the base 11 buffer the vibration. When cutting inside the circular casing 9, after the pump 23 is started, the water in the water tank 17 flows into the interior of the circular casing 9 through the circulation pipe 19 and the through pipe 18, so that the water cools and cleans the cut plastic particles. The two arc-shaped water shields 24 block most of the water, preventing a large amount of water from flowing from the rotating hole 14 to the motor 12. The support rod 25 supports the pipe 18. The two filter layers 26 filter out the foam in the water after washing plastic particles, protect the pump 23, and prevent the plastic particles from falling off the baffle 27. The collection box 28 facilitates the collection of plastic particles. The fan 30 is turned on to blow air onto the plastic particles that fall on the upper surface of the inclined screen 16 to speed up their drying. After drying, the plastic particles that fall on the upper surface of the inclined screen 16 are gathered into the collection box 28 by a wooden rake 32.
