Description
Technical Field
[0001] The utility model belongs to the technical field of plastic recycling, and in particular relates to an engineering plastic crushing and recycling device. Background Art
[0002] Engineering plastics can be used as engineering materials and plastics that replace metals to manufacture machine parts. Engineering plastics have excellent comprehensive properties, high rigidity, low creep, high mechanical strength, good heat resistance, good electrical insulation, and can be used for a long time in harsh chemical and physical environments. They can replace metals as engineering structural materials. After engineering plastics are damaged during use, they need to be recycled to avoid waste and environmental pollution.
[0003] In the prior art, after searching Chinese patent number CN219726879U, a plastic crushing and screening machine is disclosed, which includes a crushing shell, a spraying assembly and a dust suction assembly. A mounting base is fixedly installed at the bottom of the crushing shell, a storage water tank is fixedly installed on the right side of the top of the mounting base, and the dust suction assembly is located on the right side of the crushing shell; the spraying assembly is located on the inner top wall of the crushing shell; the spraying assembly includes a spraying water pipe and a spray nozzle. The plastic crushing and screening machine allows the spray emitted by the spraying assembly to contact with the dust, reducing the dust pollution, thereby preventing secondary pollution.
[0004] Usually, the shapes and sizes of broken engineering plastic waste vary. During the crushing process of batch plastics, the crushing mechanism will overheat for a long time, causing the plastic to melt and soften after contact. As a result, some plastic fragments are easily adhered to the surface of the crushing mechanism, and the crushed fragments are accumulated inside the crushing mechanism. If not cleaned in time, it will affect the normal operation of the crushing mechanism, and thus affect the efficiency of plastic crushing and recycling.
[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0027] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0029] See also Figure 1-Figure 4 As shown, the utility model is an engineering plastic crushing and recycling equipment, including a workbench 1, a crushing barrel 2 is fixedly installed inside the workbench 1, a rotating motor 3 is fixedly installed inside the workbench 1, the output end of the rotating motor 3 is fixedly connected to a rotating shaft 4, the outer surface of the rotating shaft 4 is fixedly connected to a rotating drum 5, the outer surfaces of the rotating drum 5 are respectively fixedly connected to a spiral auger 6 and a crushing blade 18, a displacement motor 7 is fixedly installed on the outer surface of the workbench 1, the output end of the displacement motor 7 is fixedly connected to a spiral shaft 8, the outer surface of the spiral shaft 8 is provided with a pushing block 9, one end of the pushing block 9 is fixedly connected to a spring 10, and one end of the spring 10 is fixedly connected to a scraper 11.
[0030] When in use, the rotating motor 3 is started to drive the rotating shaft 4 to rotate, and the sleeve 5 outside the rotating shaft 4 drives the spiral auger 6 and the crushing blade 18 to operate. The spiral auger 6 quickly transfers the plastic to the surface of the high-speed crushing blade 18 below so that it is peeled and crushed, and there is a certain gap between the outer edge of the crushing blade 18 and the inner wall of the crushing barrel 2. The displacement motor 7 is started to drive the spiral shaft 8 to rotate, and the spiral shaft 8 continuously rotates to displace the push block 9 in the direction away from one end of the scraper 11. The push block 9 continuously displaces the push spring 10 and the scraper 11 to extend to the inner wall of the crushing barrel 2. When the outer edge of the crushing blade 18 adheres to some plastic fragments, it shortens the distance between the crushing blade 18 and the inner wall of the crushing barrel 2, and then can contact the scraper 11 to scrape the plastic fragments. While contacting and scraping the plastic, the spring 10 shrinks back due to the reverse force.
[0031] The spiral shaft 8 can rotate forward or reversely. When the spring 10 retracts due to the reaction force, the spiral shaft 8 rotates in the opposite direction to drive the push block 9 to move in the opposite direction, so that the scraper 11 can move back and forth.
[0032] The utility model drives the spiral shaft 8 to rotate and push the push block 9 to move through the displacement motor 7, thereby pushing the front spring 10 and the scraper 11 to move toward the inside of the crushing barrel 2. Since the crushing blade 18 will become hot due to long-term high-speed operation, the crushing blade 18 enters the inner side of the crushing barrel 2, and the contact distance with the crushing blade 18 can be shortened. When the crushing blade 18 softens and adheres to its outer surface due to the high-temperature melted plastic, the scraper 11 is continuously displaced and the crushing blade 18 is operated at a high speed to scrape and clean it, so as to prevent excessive plastic from adhering to the outer surface of the crushing blade 18 and affecting the subsequent crushing effect.
[0033] In addition, in specific applications, when the crushing blade 18 passes the position of the scraper 11, the plastic contacts the scraper 11 to generate a reverse force on the spring 10, causing it to retract in the opposite direction, resulting in the scraper 11 being recovered in the opposite direction, and the pushing block 9 repeatedly makes a reciprocating motion to drive the scraper 11 to make a reciprocating motion, thereby cleaning the crushing blade 18 without hindering its subsequent normal operation.
[0034] In one embodiment, for the through groove 12 , the workbench 1 is provided with a through groove 12 , the inner wall of the crushing barrel 2 is provided with a side groove 13 matching the scraper 11 , and the side groove 13 is provided with a circular hole 14 corresponding to the spring 10 .
[0035] The through groove 12 is located inside the workbench 1, corresponding to the movement trajectory of the spiral shaft 8 and the push block 9. When the spring 10 and the scraper 11 move toward the crushing barrel 2, their movement trajectories extend toward the inside of the crushing barrel 2 along the side groove 13. The scraper 11 is reversely recovered and stored in the inside of the side groove 13. The cooperation between the side groove 13 and the circular hole 14 can provide a reciprocating movement storage space for the scraper 11 and the spring 10.
[0036] In one embodiment, for the push plate 16, a discharge port 15 is provided on the outer surface of the crushing barrel 2, and a push plate 16 is fixedly connected to the bottom of the rotating drum 5;
[0037] A discharge platform 17 is hingedly connected inside the workbench 1 , and an end of the discharge platform 17 extends to the outside of the discharge port 15 . The push plate 16 and the rotating drum 5 are symmetrically arranged about the axis.
[0038] When the drum 5 keeps running, the push plate 16 at the bottom of the drum 5 also runs, and the discharge port 15 passes through the inner side of the crushing barrel 2. The outer edge of the push plate 16 is close to the inner wall of the crushing barrel 2. The continuous running pushes the plastic to be discharged along the discharge port 15 until it flows to the upper surface of the discharge table 17.
[0039] By arranging a push plate 16 at the bottom position of the rotating drum 5, the continuous operation of the push plate 16 can push the plastic fragments accumulated at the bottom to move, so that centrifugal force is generated inside the crushing barrel 2, thereby quickly discharging the materials along the discharge port 15, and the outer edge of the push plate 16 is close to the inner wall of the crushing barrel 2, and the fragments adhering to the inner wall surface can be scraped off and dropped together until they flow through the discharge port 15 and are output to the upper surface of the discharge table 17 for discharge, thereby avoiding the situation where a large amount of fragments accumulate inside the crushing barrel 2 and cannot be discharged in time to cause blockage.
[0040] In addition, in specific applications, the pusher plate 16 is symmetrically arranged on the axis of the drum 5, thereby shortening the contact time with the crushed materials and increasing the efficiency of pushing and discharging the materials.
[0041] In one embodiment, for the vibration motor 20, a mounting groove 19 is provided inside the workbench 1, and the vibration motor 20 is fixedly installed inside the mounting groove 19;
[0042] The vibration motor 20 is located directly below the discharging platform 17 , and the vibration motor 20 is fixedly connected to the discharging platform 17 .
[0043] The vibration motor 20 is located directly below the discharge table 17 and its top is fixedly connected to the discharge table 17. When the vibration motor 20 is started, it drives the discharge table 17 to vibrate, and the end of the discharge table 17 is hinged to the inside of the workbench 1. When the discharge table 17 vibrates, the plastic on the surface shakes.
[0044] By adding a vibration motor 20 at the bottom of the discharge platform 17, the discharge platform 17 continuously vibrates to increase the fluidity of the plastic pushed out from its surface, thereby preventing the broken plastic from accumulating on the upper surface of the discharge platform 17 and affecting the overall discharge efficiency.
[0045] In one embodiment, for the above-mentioned material guide trough 21, the outer surface of the workbench 1 is provided with a material guide trough 21, the end of the discharge platform 17 extends to the outer edge of the material guide trough 21, and the outer surface of the workbench 1 is fixedly connected with a material guide hopper 22.
[0046] The discharge platform 17 is located inside the guide trough 21, the discharge port of the guide trough 21 is connected to the discharge platform 17, and the guide hopper 22 is close to the outside of the guide trough 21. The plastic flowing on the surface of the discharge platform 17 is finally output to the inside of the guide hopper 22 through the guide trough 21, and is finally output by the guide hopper 22. In this way, the flow channel of the crushed plastic can be linear, thereby improving the plastic discharge and recovery efficiency.
[0047] In one embodiment, for the square holes 23 , a plurality of square holes 23 are provided on the outer surface of the crushing barrel 2 .
[0048] By providing a plurality of through square holes 23 , the air circulation channel inside the crushing barrel 2 can be increased, thereby improving the heat dissipation effect and reducing the high temperature influence of the crushing blade 18 .
[0049] In summary, with the aid of the above technical scheme of the utility model, the side groove 13 and the circular hole 14 cooperate to provide a reciprocating motion storage space for the scraper 11 and the spring 10, so that the scraper 11 has a fixed motion trajectory to remove sticky plastics, and the continuous operation of the push plate 16 can make the plastic fragments move to generate centrifugal force, so that they can be discharged quickly from the discharge port 15, and the push plate 16 can scrape off the fragments adhered to the inner wall surface of the crushing barrel 2 while it is running, so as to prevent the plastic fragments from sticking, and avoid a large amount of fragments from accumulating inside the crushing barrel 2 to cause blockage, the vibration motor 20 drives the discharge table 17 to continuously vibrate, increase the fluidity of the plastic fragments, and thereby prevent the broken plastics from accumulating on the upper surface of the discharge table 17 to affect the discharge efficiency, the crushed plastic circulation channel is linear, and the plastic discharge recovery efficiency is improved, the square hole 23 increases the air circulation channel inside the crushing barrel 2, improves the heat dissipation effect, and reduces the high temperature influence of the crushing blade 18.
[0050] Through the above technical scheme, 1. The utility model drives the spiral shaft 8 to rotate through the displacement motor 7 to push the push block 9 to move, thereby pushing the front spring 10 and the scraper 11 to move toward the inside of the crushing barrel 2. Since the crushing blade 18 will become hot due to long-term high-speed operation, the crushing blade 18 enters the inner side of the crushing barrel 2, which can shorten the contact distance with the crushing blade 18. When the crushing blade 18 softens and adheres to its outer surface due to the high-temperature molten plastic, it is scraped and cleaned by the continuous displacement of the scraper 11 and the high-speed operation of the crushing blade 18, so as to prevent excessive plastic from adhering to the outer surface of the crushing blade 18 and affecting the subsequent crushing effect; 2. The utility model adds a vibration motor 20 at the bottom of the discharging table 17, so that the discharging table 17 continuously vibrates, increases the fluidity of the plastic pushed out from its surface, and prevents the broken plastic from accumulating on the upper surface of the discharging table 17 and affecting the overall discharging efficiency.
