[0019] Compared with the prior art, the present invention provides a plastic pelletizing machine for rapidly cooling plastic parts, which has the following beneficial effects:

[0020] 1. A plastic pellet extractor for rapidly cooling plastic parts. By setting a water pump, the cooling liquid in the collection box is always in a flowing state, so that the plastic particles dropped into the collection box are in an active state, and the incompletely cooled plastic particles are prevented from sticking to each other. Moreover, by setting a cooling device, the liquid generating heat in the collection box is cooled, so as to ensure that the cooling liquid in the collection box is always in a low temperature state, thereby achieving rapid cooling of the plastic particles, and solving the problem that after the hot plastic particles enter the cooling liquid, the heat therein will increase the temperature of the cooling liquid, thereby causing the subsequent plastic particles to be unable to be completely cooled.

[0021] 2. A plastic pellet extractor for rapidly cooling plastic parts. Through power transmission between a transmission part, a switch part and an adjusting part, after the plastic particles are completely processed, the adjusting part operates and allows cooling liquid to enter a water storage bin, and then drives the switch part to operate, so that the processed plastic particles in the collection box are stored in the storage box, thereby avoiding the problem of cooling liquid flowing out when the processed plastic particles are collected, resulting in a waste of cooling liquid.

[0022] 3. A plastic pellet extractor for rapidly cooling plastic parts. When the cooling liquid in the collection box is cooling the plastic particles, the movable mesh plate rotates and intercepts the opening between the collection box and the water inlet box, thereby intercepting large plastic particles on the side of the movable mesh plate close to the water inlet box, and driving qualified plastic particles and small plastic particles into between the movable mesh plate and the filter plate through the fluidity of the water flow, and driving small plastic particles into between the filter plate and the partition screen through the fluidity of the water flow, thereby classifying and collecting plastic particles of different sizes.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a plastic pelletizing machine for rapidly cooling plastic parts.

[0034] Embodiment 1:

[0035] See also Figure 1-Figure 3 A plastic granulator for rapidly cooling plastic parts, comprising a granulator 1, a collecting device 2 is arranged at the outlet of the granulator 1, the collecting device 2 comprises a collecting box 3 and a cooling circulation component 4 arranged outside the collecting box 3, and a storage box 5 is arranged at the bottom of the collecting box 3;

[0036] The cooling circulation assembly 4 includes a connecting pipe 41, a water inlet box 42 and a water outlet box 43 fixedly installed at both ends of the connecting pipe 41, a cooling device 44 and a water pump 45 are fixedly installed on the connecting pipe 41, and the water inlet box 42 and the water outlet box 43 are fixedly installed at both ends of the collecting box 3 and are connected to each other;

[0037] A water storage bin 46 is fixedly connected to the bottom of the water inlet tank 42, and an adjusting member 47 is provided between the water storage bin 46 and the water inlet tank 42 to control the water in the water inlet tank 42 to enter the water storage bin 46;

[0038] A switch 48 is provided between the storage box 5 and the collection box 3 so that the plastic pellets in the collection box 3 can be stored in the storage box 5;

[0039] A transmission member 49 is provided between the adjustment member 47 and the switch member 48. When the collecting device 2 completes collecting the plastic particles, the adjustment member 47 operates and allows the water in the cooling circulation device to enter the water storage tank 46, and then drives the switch member 48 to operate and allows the plastic particles in the collecting box 3 to enter the storage box 5.

[0040] Specifically, after the plastic particles processed by the granulator 1 enter the collection box 3, the water pump 45 and the cooling device 44 are operated at the same time, so that the water in the collection box 3 is in a flowing state, so that the plastic particles in the collection box 3 are in a free state driven by the water flow, thereby avoiding contact and adhesion between the plastic particles, and through the setting of the cooling device 44, the water liquid with a certain temperature in the collection box 3 is cooled, and enters the collection box 3 through the connecting pipe 41 and the water inlet box 42, thereby ensuring that the water liquid in the collection box 3 always maintains a cooling temperature. When the plastic particles are manufactured, the water flows into the water storage bin 46 through the setting of the transmission part 49, and the cooled plastic particles are collected into the storage box 5 through the switch part 48, thereby avoiding the waste of water flow in the process of collecting the plastic particles;

[0041] By setting the water pump 45, the cooling liquid in the collection box 3 is always in a flowing state, so that the plastic particles falling into the collection box 3 are in an active state, preventing the plastic particles that have not been completely cooled from sticking to each other, and by setting the cooling device 44, the liquid that generates heat in the collection box 3 is cooled, thereby ensuring that the cooling liquid in the collection box 3 is always in a low temperature state, thereby achieving rapid cooling of the plastic particles, and solving the problem that after the plastic particles with heat enter the cooling liquid, the heat therein will cause the temperature of the cooling liquid to rise, thereby causing the subsequent plastic particles to be unable to be completely cooled.

[0042] Embodiment 2:

[0043] The difference from the above embodiment 1 is that, see Figure 3-Figure 4 For the above-mentioned collecting box 3 and storage box 5, the switch member 48 includes a plurality of rotating plates 481, which are all arranged at the connection between the collecting box 3 and the storage box 5. The rotating plates 481 are rotatably connected to the collecting box 3 through bearings. When the plurality of rotating plates 481 are in a horizontal state, the ends thereof are close together.

[0044] A classification component 6 is provided in the collection box 3, and the classification component 6 includes a movable mesh plate 61, a filter plate 62 and a partition 63. The movable mesh plate 61 is rotatably connected to the collection box 3 through a bearing and is located near the side of the water inlet box 42. An extension rod is fixedly connected to the top of the movable mesh plate 61. The extension rod is rotatably connected to the collection box 3 through a bearing and extends to the top of the collection box 3. A second motor 64 is fixedly connected to the top of the collection box 3. The output end of the second motor 64 is fixedly connected to one end of the extension rod. The filter plate 62 is fixedly provided in the collection box 3 and is located near the side of the water outlet box 43. The partition 63 is fixedly installed between the collection box 3 and the water outlet box 43. A plurality of partitions 65 are fixedly installed in the storage box 5.

[0045] The movable mesh plate 61 includes a rotating mesh plate 611 and a movable mesh plate 612. A guide groove 613 is provided on one side of the rotating mesh plate 611, and a guide rod is fixedly connected in the guide groove 613. A guide block 614 is fixedly connected on one side of the movable mesh plate 612. The guide block 614 is slidably connected to the rotating mesh plate 611 through the guide groove 613 and is sleeved on the outer periphery of the guide rod. A second spring 615 is fixedly connected on one side of the guide block 614, and the second spring 615 is arranged outside the guide rod. An arc is set at one corner in the collection box 3, so that when the movable mesh plate 61 rotates, one end of the movable mesh plate 612 fits against the inner wall of the collection box 3.

[0046] Specifically, when the collection of plastic particles is completed, the water pump 45 and the cooling device 44 continue to operate. At this time, the second motor 64 drives the extension rod and the movable mesh plate 61 fixedly connected to the extension rod to rotate. The sliding connection between the movable mesh plate 612 and the rotating mesh plate 611 and the elastic force provided by the second spring 615 increase the distance between the movable mesh plate 612 and the rotating mesh plate 611 during the rotation of the movable mesh plate 61. In addition, the arc-shaped corner of the collecting box 3 is set so that one end of the movable mesh plate 612 is always in contact with the inner wall of the collecting box 3, thereby moving the plastic particles in the collecting box 3 to one side. During the movement, the mesh diameter on the surface of the movable mesh plate 61 is set to be larger than the diameter of qualified plastic particles, and the impact of the water flow makes the qualified diameter and the excessive diameter of the plastic particles be collected. Small plastic particles pass through the movable mesh plate 61, and plastic particles with a diameter larger than that of qualified plastic particles are collected on the side of the movable mesh plate 61 close to the water inlet tank 42. At the same time, through the fluidity of the water flow, plastic particles with a diameter smaller than that of qualified plastic particles between the movable mesh plate 61 and the filter are pushed into the space between the filter and the partition 63, thereby classifying the collected plastic particles. Then the transmission member 49 operates, driving the adjustment member 47 to operate, so that the water in the collection box 3 is collected into the water storage bin 46, and then driving the switch member 48 to operate, so that the multiple rotating plates 481 at the bottom of the collection box 3 rotate downward, so that the classified plastic particles in the collection box 3 fall into the storage box 5, and through the setting of multiple partitions 65 in the storage box 5, the plastic particles in the storage box 5 are in a classified collection state.

[0047] Embodiment three:

[0048] The difference from the above-mentioned embodiment 2 is that, see Figure 5-Figure 8 For the above-mentioned adjusting member 47, the adjusting member 47 includes a water baffle 471, which is arranged at the connection between the water storage bin 46 and the water inlet tank 42. Slide grooves 472 are provided on both sides of the water storage bin 46. Slide blocks 473 are fixedly connected on both sides of the water baffle 471. The slide blocks 473 are slidably arranged in the slide grooves 472. A screw rod 474 is rotatably connected in the slide grooves 472 through bearings. The screw rod 474 is threadedly connected to the slide block 473.

[0049] Both sides of the water inlet box 42 are rotatably connected to a rotating rod 475 through bearings, a first bevel gear 476 is fixedly connected to the rotating rod 475, a second bevel gear 477 is fixedly connected to the top of the screw 474, the first bevel gear 476 is meshed with the second bevel gear 477, and both ends of the outer side of the water inlet box 42 are rotatably connected to pulleys 478 through bearings, the pulley 478 is fixedly connected to one end of the rotating rod 475, and a transmission belt 479 is sleeved on the outer periphery of the two pulleys 478;

[0050] Specifically, the transmission member 49 runs, driving one of the rotating rods 475 to rotate, thereby driving one of the pulleys 478 to rotate. The transmission belt 479 is arranged on the two pulleys 478 to drive the two pulleys 478 to rotate, thereby driving the two rotating rods 475 to rotate at the same time, and then driving the first bevel gear 476 to rotate. Through the meshing connection between the first bevel gear 476 and the second bevel gear 477, the second bevel gear 477 and the screw 474 fixedly connected to the second bevel gear 477 are driven to rotate. Through the threaded connection between the screw 474 and the slider 473, the slider 473 and the water-blocking plate 471 fixedly connected to the slider 473 are driven to move, so that when the partition 65 moves downward, the water in the water inlet tank 42 flows into the water storage bin 46, thereby collecting the water in the collection box 3 into the water storage bin 46. When the partition 65 moves upward, the water in the water storage bin 46 surges into the water inlet tank 42, so that the water enters the collection box 3 again and is cooled.

[0051] Embodiment 4:

[0052] The difference from the above-mentioned embodiment 3 is that, see Figure 5-Figure 8For the above-mentioned transmission member 49, the transmission member 49 includes a first worm wheel 491 and a first worm 494, a transfer member 492 is arranged between the first worm wheel 491 and one of the rotating rods 475, a plurality of fixed seats 493 are fixedly connected to one side of the water inlet tank 42, one end of the first worm 494 is rotatably connected to one of the fixed seats 493 through a bearing, a first motor 495 is fixedly connected to one side of one of the fixed seats 493, an output end of the first motor 495 is fixedly connected to one end of the first worm 494, the first worm 494 is meshedly connected to the first worm wheel 491, a cylinder 496 is rotatably connected to the other fixed seat 493 through a bearing, a servo cylinder 497 is fixedly connected to one side of the cylinder 496, a connecting rod 498 is fixedly connected between the servo cylinder 497 and the first worm 494;

[0053] A piston rod 499 is fixedly connected to the other side of the cylinder 496, one end of the piston rod 499 is fixedly connected to the output end of the servo cylinder 497, a cross slot 4910 is provided in the piston rod 499, a moving rod 4911 is slidably connected in the cross slot 4910, a cross block 4912 matching the cross slot 4910 is fixedly connected to the outer periphery of the moving rod 4911, the cross block 4912 is slidably connected to the cross slot 4910, one end of the cross block 4912 is fixedly connected to a first spring 4913, the first spring 4913 is arranged in the cross slot 4910, and one end of the moving rod 4911 is fixedly connected to a clamping block 4914;

[0054] The transport member 492 includes a hinged plate 4921, an inner rod 4922 is fixedly connected to one end of the first worm gear 491, an outer rod 4923 is rotatably connected to one side of the water inlet tank 42 through a bearing, an inner groove is provided at one end of the outer rod 4923, the inner rod 4922 is sleeved in the inner groove and is rotatably connected to the outer rod 4923 through a bearing, the hinged plate 4921 is arranged on the outer periphery of the inner rod 4922 and is hinged to the inner rod 4922, two torsion springs 4924 in opposite directions are installed at the hinge between the hinged plate 4921 and the inner rod 4922, a baffle 4925 is fixedly connected to the inner wall of the inner groove, and the hinged plate 4921 is in contact with the baffle 4925;

[0055] The transmission member 49 further includes a second worm 4915 and a second worm wheel 4917. A plurality of bearing seats are fixedly connected to the outer side of the collection box 3. A movable rod 4916 is rotatably connected to the bearing seat through a bearing. A plurality of second worms 4915 are fixedly mounted on the movable rod 4916. The second worm wheel 4917 is rotatably connected to the collection box 3 through a bearing and is fixedly connected to the rotating plate 481. The second worm wheel 4917 is meshedly connected to the second worm 4915. A slot 4918 is provided at one end of the movable rod 4916. The block 4914 and the slot 4918 are matched with each other.

[0056] Specifically, the first motor 495 runs, driving the first worm 494 to rotate, and the meshing connection between the first worm 494 and the first worm wheel 491 drives the first worm wheel 491 to rotate, thereby driving the inner rod 4922 to rotate, so that the hinged plate 4921 on the outer side of the inner rod 4922 contacts the partition 65 on the inner wall of the outer rod 4923, and through the setting of the torsion spring 4924, the hinged plate 4921 drives the outer rod 4923 to rotate, thereby driving the rotating rod 475 to rotate, and then driving the water baffle 471 to move downward, so that the water in the water inlet tank 42 flows into the water storage bin 46, and when the water baffle 471 moves downward to near the bottom of the water storage bin 46, the water in the collection box 3 is completely collected in the water storage bin 46, and the water baffle 471 continues to move downward. When the water-blocking plate 471 moves to the bottom of the water storage tank 46, the outer rod 4923 cannot rotate. Through the movable hinge between the hinge plate 4921 and the inner rod 4922 and the setting of the torsion spring 4924, the hinge plate 4921 itself rotates, so that when the outer rod 4923 does not rotate, the inner rod 4922 can continue to rotate, thereby causing the first worm 494 to continue to rotate. At this time, the servo cylinder 497 drives the piston rod 499 to move forward. At this time, through the setting of the connecting rod 498 and the rotation connection between the cylinder 496 and the fixed seat 493, the first worm 494 rotates and drives the servo cylinder 497 and the piston rod 499 to rotate continuously. When the piston rod 499 drives the movable rod 4911 to move to the movable rod 4916 When the movable rod 4911 is moved to the left, the block 4914 contacts one end of the movable rod 4916, and the movable rod 4911 is driven to rotate by the sliding connection between the movable rod 4911 and the piston rod 499, and the setting that the connecting rod 498 drives the servo cylinder 497 to rotate. During the rotation of the movable rod 4911, the block 4914 overlaps with the card slot 4918, thereby driving the second worm 4915 to rotate, and the meshing connection between the second worm 4915 and the second worm gear 4917 drives the second worm gear 4917 to rotate, thereby driving the rotating plate 481 to rotate, and then the plastic particles on the rotating plate 481 fall into the storage box 5. During this process, the servo cylinder 497 continuously drives the piston rod 499 to move forward, and the movable rod 4911 and the piston rod 499 are connected to each other. The sliding connection and the elastic force provided by the first spring 4913 reduce the distance between the piston rod 499 and the moving rod 4911. The first spring 4913 is in a compressed state and does not affect the movement of the moving rod 4911 to drive the second worm 4915 to rotate. When the plastic particles on the rotating plate 481 are stored in the storage box 5, the first motor 495 runs in the reverse direction, driving the first worm 494 to run in the reverse direction, thereby driving the water barrier 471 to move upward. During the upward movement of the water barrier 471 for a certain distance, the water in the water storage tank 46 will not overflow from the water storage tank 46. In this process, the connecting rod 498 drives the servo cylinder 497 and the piston rod 499 and the moving rod 4911 to rotate in the opposite direction. At this time, the servo cylinder 497 drives the piston rod 499 to move backward at the same time.During the movement, the first spring 4913 is released from the compressed state and restores its elasticity, so that when the piston rod 499 moves backward, the block 4914 at one end of the moving rod 4911 always overlaps with the slot 4918. When the rotating plate 481 rotates in the opposite direction and the multiple rotating rods 475 are in a horizontal state, the block 4914 separates from the slot 4918, and the movable rod 4916 no longer rotates. At this time, the second worm 4915 continues to rotate, driving the water baffle 471 to move upward, so that all the water in the water storage tank 46 is discharged from the water storage tank 46, thereby realizing the next round of cooling.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
