Description

Technical Field

[0001] The utility model relates to the technical field of waste battery plastic shell recycling, and particularly relates to a plastic strip granulator. Background Art

[0002] The shell of waste batteries is made of metal materials or plastics. Different recycling and granulation methods are adopted according to different battery types. For batteries with plastic shells, they are generally disassembled and sorted, and the plastics are washed, crushed, dried, and sorted to obtain plastic sheets of different colors and qualities. Then, they are sent into the feeding bin by a screw conveyor and plasticized by a plastic extruder to form plastic strips. After the plastic strips are cooled in a cooling tank, the moisture on their surfaces needs to be removed, and then they are granulated by a granulator. After grading, they enter the ton bag bin device for stacking and external sales, so as to improve the recycling rate of waste battery shells.

[0003] The patent document with the publication number of CN212666186U discloses a granulator for processing rubber and plastic strips. The granulator realizes the up and down adjustment of the pressing plate through the cooperation of a turntable, a lead screw, a pressing plate, etc., and then realizes the fixation of the plastic strip, avoiding the problem that the plastic strip is prone to dislocation during cutting due to the inability to press the plastic strip tightly, resulting in uneven sizes of the cut plastic particles. However, the above granulator cannot effectively handle the problem of particle adhesion after granulation, and at the same time, it cannot dry the plastic strip.

[0004] The patent document with the application number of CN202321838355.9 discloses a plastic strip granulator with adjustable cutting width. When in use, the plastic strip is placed on the guiding rotating shaft in the plastic strip guiding mechanism to transmit the plastic strip to the plastic cutting plate. The cutting blade makes a reciprocating up and down movement through the plastic cutting lifting mechanism to granulate the plastic strip. The obtained plastic particles after cutting roll onto the plastic particle transmission mechanism through the plastic cutting plate, and then the plastic particle transmission mechanism transmits the plastic particles to the plastic particle discharge plate to make the plastic particles automatically discharge. The distance between the cutting blades can be adjusted by the blade spacing adjusting rod on the cutting knife adjustment fixing frame, so as to produce plastic particles of different widths when cutting the plastic strip. However, when adjusting the distance between the cutting knives of this granulator, it needs to be adjusted one by one, and the adjustment efficiency is low. Summary of the Utility Model

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0046] Embodiment 1: Refer to Figures 1 - 4 As shown, a plastic strip granulator includes a housing 1. Two upper and lower symmetric guide rollers 2 are rotatably arranged in the housing 1, and a motor for driving the rotation of the guide rollers 2 is fixed outside the housing 1. During the rotation of the two guide rollers 2, the plastic strip between the two guide rollers 2 can be conveyed into the housing 1.

[0047] A filter screen 3 is fixed in the housing 1. A buckle cover 4 is fixed in the housing 1 below the filter screen 3. The upper end of the buckle cover 4 is open, the upper end of the buckle cover 4 is fixedly connected to the lower end of the filter screen 3, and the lower end of the buckle cover 4 is fixedly communicated with a connecting pipe 5. The connecting pipe 5 is communicated with an exhaust fan outside the housing 1. When the exhaust fan is started, the air passes through the filter screen 3 and is discharged through the buckle cover 4, the connecting pipe 5 and the exhaust fan. The plastic strip moving above the filter screen 3 can be dried.

[0048] A cutting plate 6 is fixed in the housing 1. A granulating assembly is slidably arranged in the upper housing 1, and a guide plate 10 is fixed in the housing 1.

[0049] The filter screen 3 is located in the housing 1 between the two guide rollers 2 and the cutting plate 6, and the cutting plate 6 is located between the guide plate 10 and the filter screen 3. One end of the cutting plate 6 facing the guide plate 10 is inclined downward, and one end of the guide plate 10 away from the cutting plate 6 is inclined downward.

[0050] The granulating assembly includes a sliding frame 7 slidably arranged in the housing 1. Specifically, a slider 14 is fixed on the sliding frame 7, a guide groove 8 is opened in the housing 1, and the slider 14 is slidably clamped in the guide groove 8. The sliding frame 7 is in an inverted U shape and is parallel to the cutting plate 6. A cylinder 9 is fixed at the upper end of the housing 1, and the telescopic rod 24 of the cylinder 9 is fixedly connected to the upper end of the sliding frame 7.

[0051] On the opposite end faces of the two side walls of the sliding frame 7, sliding grooves 15 are provided. A plurality of sliding rods 16 are equidistantly arranged in the sliding grooves 15. Adjacent sliding rods 16 are connected by tension springs 18. Cutting knives 17 are fixed to the lower ends of the sliding rods 16. The leftmost sliding rod 16 is fixedly connected to the sliding frame 7, and the remaining sliding rods 16 are slidably arranged in the sliding grooves 15. Shearing forks 19 are arranged at the upper ends of the sliding rods 16. The central axes 20 of the shearing forks 19 are rotatably connected to the sliding rods 16. The ends of adjacent shearing forks 19 are rotatably connected by connecting shafts 21. Push rods 22 are fixed to the free ends of the shearing forks 19 above the sliding rod 16 fixedly connected to the sliding frame 7. Push plates 23 are arranged on one side of each push rod 22. The two push rods 22 are located between the two push plates 23. The sliding rod 16 fixedly connected to the sliding frame 7 and the push plate 23 are connected by a telescopic rod 24. Specifically, the sliding rod 16 fixedly connected to the sliding frame 7 is fixedly connected to one end of the telescopic rod 24, and the other end of the telescopic rod 24 is fixedly connected to the push plate 23.

[0052] After the plastic strip moves onto the cutting plate 6, the air cylinder 9 causes the cutting component to reciprocate up and down. The cutting knives 17 of the cutting component can cut the plastic strip into particles. Since one end of the cutting plate 6 facing the material guiding plate 10 is inclined downward, one end of the material guiding plate 10 away from the cutting plate 6 is inclined downward. The plastic particles can be discharged to the outside of the housing 1 through the cutting plate 6 and the material guiding plate 10.

[0053] When it is necessary to adjust the distance between the cutting knives 17 to change the particle size of the plastic particles, the two telescopic rods 24 are started simultaneously, so that the two push plates 23 approach each other. During the process of the two push plates 23 approaching each other, the plurality of shearing forks 19 are synchronously actuated through the two push rods 22, and the distance between the two connecting shafts 21 connecting adjacent shearing forks 19 decreases, and the distance between adjacent sliding rods 16 increases. At the same time, the distance between adjacent cutting knives 17 increases, and the tension spring 18 is stretched. After the distance between the cutting knives 17 increases, the particle size of the plastic particles generated after the plastic strip is cut by the cutting knives 17 increases.

[0054] Conversely, when it is necessary to reduce the particle size of the plastic particles, the two telescopic rods 24 are started simultaneously, so that the two push plates 23 move away from each other. Under the pulling force of the tension spring 18, the sliding rods 16 approach each other during the process of the two push plates 23 moving away from each other, the plurality of shearing forks 19 are synchronously actuated, and the distance between the two connecting shafts 21 connecting adjacent shearing forks 19 increases. At the same time, the distance between adjacent cutting knives 17 decreases. After the distance between the cutting knives 17 decreases, the particle size of the plastic particles generated after the plastic strip is cut by the cutting knives 17 becomes smaller.

[0055] When adjusting the distance between the plurality of cutting knives 17, the plurality of shearing forks 19 act simultaneously, and the distance between the plurality of cutting knives 17 can change simultaneously, and the change amount is equal, and the efficiency of adjusting the distance of the cutting knives 17 is high.

[0056] Embodiment 2: On the basis of Embodiment 1, with reference to Figure 1As shown in the figure, a baffle 11 is fixed inside the housing 1 above the material guide plate 10. A plurality of support rods 12 are fixed to the lower end of the baffle 11. There is a gap between the support rods 12 and the material guide plate 10. A vibration motor 13 is fixed on the baffle 11.

[0057] The vibration motor 13 can drive the baffle 11 and the support rods 12 to vibrate. The baffle 11 can block the plastic balls formed by sticking together a plurality of plastic particles. The vibrating baffle 11 can vibrate and disperse the plastic balls blocked by it. The plastic balls with a smaller diameter can disperse the vibrating support rods 12 after passing through the gap between the baffle 11 and the material guide plate 10.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
