Description

Technical Field

[0001] This utility model relates to a crusher for processing recycled plastics. Background Technology

[0002] Recycled plastics are the reuse of plastics. They are made by crushing plastics with mechanical blades. Recycled plastics refer to plastic raw materials that are obtained again after processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, and modification. Recycled plastics production requires crushing by a crusher.

[0003] Existing recycled plastic crushers can only crush plastic in a single operation, which can easily lead to incomplete crushing of some plastics and difficulty in crushing them to the ideal particle size, thus reducing the quality of recycled plastics. Furthermore, when using a collection box to collect the crushed plastics, the lack of a limiting structure on the collection box makes it prone to displacement during device operation, reducing the accuracy of collection. Utility Model Content

[0004] This invention addresses the problem that plastics can only be crushed once during use, which easily leads to incomplete crushing of some plastics, making it difficult to crush them to the ideal particle size and reducing the quality of recycled plastics. Furthermore, when using a collection box to collect the crushed plastics, the lack of a limiting structure on the collection box makes it prone to displacement during device operation, reducing the accuracy of collection. Therefore, this invention provides a recycled plastics processing crusher.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a recycled plastic processing crusher, including a base and a crushing chamber. Two side plates are fixedly installed on the base, and mounting shells are fixedly installed on each of the two side plates. A rotating rod is rotatably connected between the two side plates via bearings. Both ends of the rotating rod pass through the side plates and extend into the interior of the mounting shells, and are rotatably connected to the inner wall of the mounting shells via bearings. Main pulleys are sleeved inside the rotating rods in two fixed slots. Rotating shafts are rotatably connected inside the two side plates via bearings. One end of each rotating shaft extends into the interior of the mounting shell and is sleeved with a driven pulley. The two main pulleys are connected to the driven pulleys via belts. One end of each rotating shaft is fixedly installed in the same crushing chamber.

[0007] In this technical solution, two guide seats are fixedly installed inside the crushing box, and a guide port is opened on the contact surface of the crushing box at the two guide seats.

[0008] In this technical solution, threaded blocks are threadedly connected to both feed ports, and limit caps are fixedly installed on one side of each of the two threaded blocks.

[0009] In this technical solution, a first motor is fixedly installed at the bottom end of the base, and a drive gear is fixedly installed through the output shaft of the first motor through the base. A driven gear is fixedly installed on the rotating rod, and the drive gear and the driven gear are meshed and connected.

[0010] In this technical solution, a crushing assembly is provided inside the crushing box. The crushing assembly includes a crushing roller, a first rotating shaft, and a second rotating shaft. The first rotating shaft and the second rotating shaft are rotatably connected inside the crushing box via bearings. Crushing rollers are fixedly installed on both the first rotating shaft and the second rotating shaft. A fixed shell is fixedly installed on the crushing box. One end of the first rotating shaft and the second rotating shaft extends into the interior of the fixed shell and is respectively fitted with a first gear and a second gear. The first gear and the second gear are meshed and connected. A motor is fixedly installed on the crushing box, and the output shaft of the motor extends into the interior of the crushing box and is fixedly connected to the first rotating shaft.

[0011] In this technical solution, the two side plates are fixedly installed to the same fixing plate, and a collection box is provided on the fixing plate, with a handle fixedly installed on the collection box.

[0012] In this technical solution, two positioning blocks are fixedly installed at the bottom of the collection box, and two positioning slots are opened on the fixing plate, and both positioning blocks can be inserted into the positioning slots.

[0013] In this technical solution, the fixed plate has a fixed groove inside, and a screw is threadedly connected inside the fixed plate. A handwheel is fixedly installed at one end of the screw, and the other end of the screw extends into the inside of the fixed groove and is rotatably connected to a movable plate through a bearing.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] The aforementioned recycled plastic processing crusher, by setting up a rotating component and starting the first motor, drives the crushing box to move up and down. During the crushing process, this helps the plastic material to continuously tumble within the crushing box. When the crushing box is upside down, the material flows from the wide part of the crushing box to the narrow part in the middle, and then from the middle to both sides, realizing multiple cycles of material tumbling. The movement of the material in the upside-down crushing box increases the chances of collision and shearing between the plastic and the crushing component, improving the uniformity and thoroughness of crushing and improving the quality of recycled plastic.

[0019] 2. By turning the handwheel, the movable plate drives the two plug-in rods to engage with the plug-in slots on the two positioning blocks, ensuring the precise positioning of the collection box on the fixed plate. Plastic fragments or particles generated by the device must fall accurately into the collection box, preventing displacement and ensuring accurate collection. When cleaning or replacing the collection box is required, the operator can easily remove it from the fixed plate without complicated tools or numerous disassembly steps. Attached Figure Description

[0033] In this technical solution, two guide seats 9 are fixedly installed inside the crushing box 10, and the crushing box 10 has a guide port on the contact surface of the two guide seats 9.

[0034] In this technical solution, threaded blocks 7 are threadedly connected to both feed ports, and limit caps 8 are fixedly installed on one side of each of the two threaded blocks 7.

[0035] In this technical solution, a first motor 18 is fixedly installed at the bottom end of the base 1, and a drive gear 17 is fixedly installed through the output shaft of the first motor 18 through the base 1. A driven gear 19 is fixedly installed on the rotating rod 27, and the drive gear 17 and the driven gear 19 are meshed and connected.

[0036] In this technical solution, a crushing assembly is provided inside the crushing box 10. The crushing assembly includes a crushing roller 22, a first rotating shaft 21, and a second rotating shaft 23. The first rotating shaft 21 and the second rotating shaft 23 are rotatably connected inside the crushing box 10 via bearings. The crushing roller 22 is fixedly installed on both the first rotating shaft 21 and the second rotating shaft 23. A fixed shell 32 is fixedly installed on the crushing box 10. One end of the first rotating shaft 21 and the second rotating shaft 23 extends into the interior of the fixed shell 32 and is respectively fitted with a first gear 31 and a second gear 33. The first gear 31 and the second gear 33 are meshed. A second motor 30 is fixedly installed on the crushing box 10. The output shaft of the second motor 30 extends into the interior of the crushing box 10 and is fixedly connected to the first rotating shaft 21.

[0037] In this technical solution, the two side plates 3 are fixedly installed to the same fixing plate 13, the fixing plate 13 is provided with a collection box 12, and the collection box 12 is fixedly installed with a handle 34.

[0039] In this technical solution, the fixing plate 13 has a fixing groove 24 inside, and a screw 25 is threadedly connected inside the fixing plate 13. A handwheel 26 is fixedly installed at one end of the screw 25, and the other end of the screw 25 extends into the interior of the fixing groove 24 and is rotatably connected to a movable plate 28 through a bearing. Two plug-in rods 29 are fixedly installed on the movable plate 28.

[0040] In this technical solution, both positioning blocks 20 are provided with insertion slots 15, and both insertion rods 29 can extend into the interior of the positioning slots 16 and be inserted into the insertion slots 15.

[0041] In this technical solution, four support legs 14 are fixedly installed at the bottom end of the base 1.

[0042] In use, all electrical components mentioned in this application are connected to an external power supply and control switch. By rotating the limit cover 8 until the threaded block 7 is disengaged from the crushing box 10, the plastic is fed into the crushing box 10 through the feed inlet. The second motor 30 is started, and the output shaft of the second motor 30 rotates, driving the first rotating shaft 21 to rotate. With the cooperation of the first gear 31 and the second gear 33, both the first rotating shaft 21 and the second rotating shaft 23 drive the crushing roller 22 to rotate, thus crushing the plastic.

[0043] The first motor 18 is started, and its output shaft drives the drive gear 17 to rotate. The drive gear 17 drives the rotating rod 27 to rotate through the driven gear 19. The rotating rod 27 drives the two driven pulleys 5 to rotate. With the cooperation of the belt 4, the two driven pulleys 5 drive the rotating shaft 11 to rotate. The two rotating shafts 11 drive the crushing box 10 to move up and down. During the crushing process, this helps the plastic material to continuously tumble inside the crushing box 10. When the crushing box 10 is upside down, the material flows from the wide part of the crushing box 10 to the narrow part in the middle, and then flows from the middle to both sides, realizing multiple cycles of material tumbling. The movement of the material in the upside-down crushing box 10 increases the chance of collision and shearing between the plastic and the crushing components, improving the uniformity and thoroughness of crushing and improving the quality of recycled plastic.

[0044] The collection box 12 is placed on the fixed plate 13, so that both positioning blocks 20 are inserted into the positioning slots 16. The handwheel 26 is turned, and the handwheel 26 drives the screw 25 to rotate and move at the same time. With the cooperation of the fixed slot 24, the movable plate 28 drives the two insertion rods 29 to insert into the insertion slots 15 on the two positioning blocks 20. This ensures that the collection box 12 is accurately positioned on the fixed plate 13. The plastic fragments or particles generated by the device need to fall accurately into the collection box 12. This can prevent the collection box 12 from shifting and ensure that the generated plastic fragments or particles fall accurately into the collection box 12, thus ensuring the accuracy of collection. When it is necessary to clean or replace the collection box 12, the operator can easily remove the collection box 12 from the fixed plate 13 without complicated tools or a lot of disassembly steps.

[0045] The advantages of this application are:

[0046] 1. By setting up a rotating component, the first motor 18 is started, and the two rotating shafts 11 drive the crushing box 10 to move up and down. During the crushing process, it helps the plastic material to continuously turn over in the crushing box 10. When the crushing box 10 is turned upside down, the material will flow from the wide part of the crushing box 10 to the narrow part in the middle, and then flow from the middle to both sides, realizing multiple cycles of material turning over. The movement of the material in the upside-down crushing box 10 will increase the chance of plastic colliding and shearing with the crushing component, improve the uniformity and thoroughness of crushing, and improve the quality of recycled plastic.

[0047] 2. By rotating the handwheel 26, the screw 25 rotates and moves simultaneously. With the cooperation of the fixed slot 24, the movable plate 28 drives the two plug-in rods 29 to plug into the plug-in slots 15 on the two positioning blocks 20. This ensures that the collection box 12 is accurately positioned on the fixed plate 13. The plastic fragments or particles generated by the device need to fall accurately into the collection box 12. This prevents the collection box 12 from shifting and ensures that the generated plastic fragments or particles fall accurately into the collection box 12, thus guaranteeing the accuracy of collection. When it is necessary to clean or replace the collection box 12, the operator can easily remove the collection box 12 from the fixed plate 13 without complicated tools or a lot of disassembly steps.
