Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing technology, specifically to a plastic granule processing device and processing line. Background Technology

[0002] A plastic pelletizing machine is a device that processes plastic products or recycled waste plastics into plastic pellets. The plastic raw material is fed into the feed inlet of the plastic pelletizer. Driven by the rotation of the screw, the plastic raw material gradually moves forward and melts under the heat provided by the heating device. The molten plastic is extruded through a die head to form plastic strips of a specific shape and size. These plastic strips then enter a pelletizing device for cutting. The pelletizing device typically uses rotating blades to cut the plastic strips into uniform pellets.

[0003] Utility model patent CN207380575U discloses a plastic granulation thermal processing device, including a frame, a temperature controller, and a feeding trough. An extrusion cylinder is located in the upper part of the frame. A connection port communicating with the frame is opened at the lower right end of the extrusion cylinder. A motor is installed at the left end of the extrusion cylinder, extending beyond the side wall of the frame. This device, through the setting of a uniform-speed feeder, differs from conventional feeding methods by periodically opening and closing the opening between the upper feeding trough and the extrusion cylinder, allowing the raw material to enter the extrusion cylinder at a uniform speed and in a measured quantity. This avoids blockage caused by excessive raw material, ensuring the normal operation of the device. The raw material is crushed by the double-impact extrusion of the extrusion cylinder and the extruder, greatly improving processing efficiency. Simultaneously, this equipment has intelligent temperature control and temperature display, enabling constant heating temperature to ensure a constant temperature during granulation, resulting in uniformly sized and high-quality plastic granules.

[0004] However, in common plastic granule thermal processing equipment, when cooling the basic plastic strip, the plastic strip is placed on the surface of the guide roller in the cooling tank, resulting in a short movement distance of the plastic strip in the cooling tank. Therefore, a plastic granule processing device and processing line are proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plastic granule processing device and processing line, which has advantages such as conveniently placing plastic strips under the guide rollers and increasing the length of the plastic strips' movement path in the cooling tank. This solves the problem in common plastic granule heat processing devices where, when cooling the basic plastic strips, placing the plastic strips on the surface of the guide rollers in the cooling tank results in a short movement distance of the plastic strips in the cooling tank.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plastic granule processing device includes a mounting base plate, two guide frames fixedly mounted on the top of the mounting base plate, two guide shafts rotatably mounted on the inner side wall of the guide frames, guide rollers fixedly mounted on the surface of the guide shafts, a cutting component provided on one side of one of the guide frames, and a cooling tank fixedly mounted on the top of the mounting base plate, with a flipping guide component provided inside the cooling tank.

[0008] The flipping guide assembly includes two flipping shafts, each with a flipping roller fixedly mounted on its surface. Flipping limit plates are fixedly mounted at both ends of the flipping rollers. End plates are fixedly mounted at both ends of each flipping shaft. A rotating mounting plate is fixedly mounted on one side of each end plate. Two mounting side plates are fixedly mounted on the inner wall of the cooling tank. A rotating shaft is fixedly mounted on one side of each mounting side plate, and the rotating mounting plate is rotatably mounted on the surface of the rotating shaft.

[0009] Furthermore, a fixed guide shaft is rotatably mounted on the inner wall of the cooling tank, a fixed guide roller is fixedly mounted on the surface of the fixed guide shaft, and fixed limiting plates are fixedly mounted on both ends of the fixed guide roller.

[0010] Furthermore, a limiting groove is fixedly installed on the inner wall of the cooling tank, and a limiting pin is provided on one side of the limiting groove.

[0011] Furthermore, the cutting assembly includes a mounting plate fixedly installed on one side of the guide frame, a cutting motor fixedly installed on one side of the mounting plate, a cutting blade fixedly installed on the output shaft of the cutting motor, and a storage bin fixedly installed on the top of the mounting base plate, with the storage bin located below the cutting blade.

[0012] Furthermore, a discharge motor is fixedly installed on one side of the discharge frame, and the output shaft of the discharge motor is fixedly connected to one end of the discharge shaft. Two discharge gears are rotatably installed on one side of the discharge frame, and the two discharge gears mesh with each other. The two discharge gears are respectively fixedly connected to one end of the two discharge shafts.

[0013] On the other hand, this application also relates to a plastic pellet processing production line, including a support plate fixedly installed on the top of a mounting base plate, and an extrusion cylinder fixedly installed on one side of the support plate.

[0014] Furthermore, an extrusion die is fixedly installed at the output end of the extrusion cylinder, and the extrusion die is located above the cooling tank.

[0015] Furthermore, a heater is fixedly installed on the surface of the extrusion cylinder, a feed hopper is fixedly installed on the top of the extrusion cylinder, and an extrusion motor is fixedly installed on one side of the support plate.

[0016] Compared with the prior art, this utility model provides a plastic granule processing device and processing line, which has the following beneficial effects:

[0017] This plastic granule processing device and production line, by setting a flipping guide component inside the cooling tank, flips the flipping roller upwards when the plastic strip passes through the cooling tank, then flattens the flipping roller so that the plastic strip passes under the flipping roller, then passes over the top of the fixed guide roller, and then flips another flipping roller upwards. After the plastic strip passes through, the flipping roller is flattened, so that the plastic strip is in a curved state in the cooling tank, which increases the movement path length of the plastic strip in the cooling tank and improves the cooling effect. This solves the problem of common plastic granule heat processing devices, where the plastic strip is placed on the surface of the guide roller in the cooling tank when cooling the basic plastic strip, resulting in a short movement distance of the plastic strip in the cooling tank.

[0023] 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.

[0024] Please see Figures 1 to 4 A plastic granule processing device in this embodiment includes a mounting base plate 1. Two guide frames 2 are fixedly mounted on the top of the mounting base plate 1. Two guide shafts 3 are rotatably mounted on the inner side wall of the guide frames 2. Guide rollers 4 are fixedly mounted on the surface of the guide shafts 3. A cutting component is provided on one side of one of the guide frames 2. A cooling tank 9 is fixedly mounted on the top of the mounting base plate 1. A flipping guide component 10 is provided inside the cooling tank 9.

[0025] The output roller 4 rotates, pulling the plastic strip forward so that it moves in the cooling tank 9 and moves to the cutting component for cutting, thus cutting the plastic strip into granules.

[0026] The flipping guide assembly 10 includes two flipping shafts 101. A flipping roller 102 is fixedly installed on the surface of the flipping shaft 101. A flipping limit plate 1021 is fixedly installed at both ends of the flipping roller 102. An end plate 103 is fixedly installed at both ends of the flipping shaft 101. A rotating mounting plate 104 is fixedly installed on one side of the end plate 103. Two mounting side plates 105 are fixedly installed on the inner side wall of the cooling tank 9. A rotating shaft 106 is fixedly installed on one side of the mounting side plate 105. The rotating mounting plate 104 is rotatably installed on the surface of the rotating shaft 106.

[0027] One end of the flipping shaft 101 is mounted on the surface of the rotating shaft 106 via the rotating mounting plate 104, lifting one end of the flipping roller 102 and placing the plastic strip below the flipping roller 102.

[0028] Secondly, a fixed guide shaft 11 is rotatably installed on the inner side wall of the cooling tank 9, a fixed guide roller 12 is fixedly installed on the surface of the fixed guide shaft 11, and a fixed limiting plate 121 is fixedly installed at both ends of the fixed guide roller 12.

[0029] Specifically, one end of each of the two flip rollers 102 is lifted, and the plastic strip passes through the cooling tank 9. Then, one end of the flip roller 102 is lowered, and the plastic strip passes under the flip roller 102, around the top of the fixed guide roller 12, passes under the other flip roller 102, and finally leaves the cooling tank 9, thus increasing the length of the movement path of the plastic strip in the cooling tank 9.

[0030] Please see Figure 2 and Figure 4 In this embodiment, a limiting groove 13 is fixedly installed on the inner side wall of the cooling tank 9, and a limiting pin 14 passes through one side of the limiting groove 13. When the flipping roller 102 is lowered, the limiting pin 14 passes through the corresponding rotating mounting plate 104 to fix the position of the flipping roller 102.

[0031] Please see Figure 1 and Figure 2In this embodiment, the cutting assembly includes a mounting plate 5 fixedly installed on one side of the guide frame 2. A cutting motor 6 is fixedly installed on one side of the mounting plate 5, and a cutting blade 7 is fixedly installed on the output shaft of the cutting motor 6. A storage bin 8 is fixedly installed on the top of the mounting base plate 1, and the storage bin 8 is located below the cutting blade 7. The cutting motor 6 drives the cutting blade 7 to rotate, cutting the plastic strip into plastic granules, which fall into the storage bin 8.

[0032] The export frame 2 has an export motor 31 fixedly mounted on one side. The output shaft of the export motor 31 is fixedly connected to one end of the export shaft 3. Two export gears 32 are rotatably mounted on one side of the export frame 2. The two export gears 32 mesh with each other and are fixedly connected to one end of the two export shafts 3 respectively. The export motor 31 drives the export shaft 3 to rotate, which in turn drives the two export gears 32 to rotate, causing the two export rollers 4 to rotate in opposite directions, thus moving the plastic strip forward.

[0033] Please see Figure 1 The plastic pellet processing production line in this embodiment includes a support plate 15 fixedly installed on the top of the mounting base plate 1, and an extrusion cylinder 16 fixedly installed on one side of the support plate 15.

[0034] The extrusion die 17 is fixedly installed at the output end of the extrusion cylinder 16, and the extrusion die 17 is located above the cooling tank 9.

[0035] Secondly, a heater 18 is fixedly installed on the surface of the extrusion cylinder 16, a feed hopper 19 is fixedly installed on the top of the extrusion cylinder 16, and an extrusion motor 20 is fixedly installed on one side of the support plate 15. The raw material is fed into the feed hopper 19, heated to a molten state in the extrusion cylinder 16, and formed into a plastic strip through the extrusion die 17.

[0036] The working principle of the above embodiment is as follows: lift one end of the two flip rollers 102, pass the plastic strip through the cooling tank 9, lower one end of the flip roller 102, pass the plastic strip from under the flip roller 102, go around the top of the fixed guide roller 12, pass under the other flip roller 102, and finally leave the cooling tank 9, thereby increasing the length of the movement path of the plastic strip in the cooling tank 9.
