[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0039] Example 1:
[0040] Reference Figures 1-4 A thermoplastic elastomer waste collection device includes a cylindrical housing 1, such as... Figure 1As shown, the upper end of the box 1 is provided with a feed inlet and a feed pipe adapted to the feed inlet is fixedly installed. The feed pipe can be connected to the production line to realize continuous feeding. The lower end of the box 1 is provided with a discharge outlet, and an opening and closing door is connected to the box 1 on one side of the discharge outlet. A grinding plate 2 is fixedly installed inside the box 1. A motor 3 is fixedly installed at the bottom of the box 1. The output end of the motor 3 is connected to a rotating shaft 4 through a coupling. A grinding disc 5 is fixedly installed on the rotating shaft 4. The grinding disc 5 has a conical cross-section. The inner wall of the grinding plate 2 is adapted to the grinding disc 5 and forms a crushing chamber between the grinding plate 2 and the grinding disc 5. The waste material enters the crushing chamber under the action of gravity and centrifugal force, and is subjected to strong compression and friction, and is crushed into granules.
[0041] It also includes: a piston part 6 fixedly installed inside the housing 1, with an air blowing hole 201 on the grinding plate 2. Preferably, the air blowing hole 201 is an oblique hole when viewed from the front. The output end of the piston part 6 is connected to the air blowing hole 201, which can more effectively guide the gas to the bottom of the crushing chamber or the material flow direction; a vibrating plate 7, which is slidably installed on the rotating shaft 4. The vibrating plate 7 has a sieve hole 702, which can screen the particle size of the waste after preliminary crushing. A connecting rod 8 for driving the piston part 6 is fixedly installed on the vibrating plate 7 to generate a periodic air supply action; and a spreading plate 9, which is symmetrically installed on the rotating shaft 4 and rotates with it to spread the processed waste evenly.
[0042] Specifically, a first wedge block 901 is fixedly installed on the spreading plate 9, and a second wedge block 701 that abuts against the inclined surface of the first wedge block 901 is fixedly installed on the vibrating plate 7. The inclined surfaces of the two are in contact, causing the vibrating plate 7 to swing up and down, realizing the synchronous drive of the pneumatic system. No additional power source is required, saving energy consumption. At the same time, the waste material is evenly spread to the bottom of the box 1 to prevent arching and deflection, and improve the smoothness of material feeding.
[0043] This utility model provides a thermoplastic elastomer waste collection device. Waste is fed into the box 1 through the feed inlet and falls into the crushing chamber above the feed pipe. The motor 3 starts and drives the rotating shaft 4 to rotate. The conical grinding disc 5 rotates at high speed and cooperates with the grinding plate 2 to form an efficient crushing zone. The waste is repeatedly crushed and sheared in the crushing chamber, gradually reducing its volume. The vibrating disc 7 rotates with the rotating shaft 4 and generates eccentric vibration. The vibration is transmitted to the piston part 6 through the connecting rod 8, causing it to reciprocate. The piston part 6 periodically supplies air to the air blowing hole 201 to promote the material to fall and clean up residual debris. The crushed waste falls onto the surface of the vibrating disc 7. The distribution plate 9 rotates with the rotating shaft 4 and abuts against the inclined surface of the first wedge block 901 and the second wedge block 701, generating vibration. Under the action of vibration, fine particles are screened out from the screen hole 702 and evenly distributed at the bottom of the box 1, achieving stable feeding.
[0044] Example 2
[0045] The collection device provided in Example 1 has been further optimized, specifically, as follows: Figure 3 and Figure 4 As shown, a limiting seat 10 is fixedly installed on the inner wall of the housing 1 to guide the sliding trajectory of the connecting rod 8, ensuring its accurate movement direction and avoiding deviation or jamming. The connecting rod 8 is slidably installed in the limiting seat 10. The end of the connecting rod 8 away from the vibrating plate 7 is L-shaped and fixed to the driving end of the piston part 6, which can effectively convert the rotational motion of the vibrating plate 7 into the linear reciprocating motion of the piston part 6.
[0046] Specifically, a spring 801 is fitted on the connecting rod 8. The two ends of the spring 801 are fixedly connected to the limiting seat 10 and the grinding plate 2, respectively, to provide restoring force and ensure that the connecting rod 8 can automatically reset when there is no external force, thereby realizing the periodic movement of the connecting rod 8.
[0047] With the above structure, the rotation of the vibratory plate 7 causes the connecting rod 8 to slide up and down within the limit seat 10. When the connecting rod 8 moves downward, it compresses the spring 801 and pushes the piston part 6 forward, spraying gas from the air blowing hole 201. As the connecting rod 8 rebounds upward, the spring 801 returns to its original state, pulling back the piston part 6 and completing one air supply cycle. This process is repeated continuously to keep the material in the crushing chamber flowing smoothly and prevent blockage.
[0048] Example 3
[0049] The collection device provided in Example 2 has been further optimized, specifically, as follows: Figure 3 and Figure 4 As shown, the piston part 6 includes a sleeve 601, and a piston plate 602 is fixedly installed inside the sleeve 601. The piston plate 602 can reciprocate along the inside of the sleeve 601. A push rod 603 is fixedly installed on the connecting rod 8. The push rod 603 is fixed to the piston plate 602 and is used to transmit the linear motion of the connecting rod 8 to the piston plate 602. A first hose 604 and a second hose 605 are fixedly installed on the sleeve 601. The first hose 604 is used to seal and connect to the air blowing hole 201 to supply air to the grinding plate 2. The second hose 605 is used to connect to an external air source to ensure the gas supply inside the sleeve 601. One-way valves with opposite directions are fixedly installed inside both the first hose 604 and the second hose 605 to control the gas flow direction and prevent backflow.
[0050] To prevent dust or impurities from affecting the normal operation of the equipment, a ventilation hole 101 is further provided on the housing 1, and the second flexible hose 605 is sealed to the ventilation hole 101. A filter screen 102 is fixedly installed inside the ventilation hole 101.
[0051] With the above structure, when the vibratory plate 7 rotates, the connecting rod 8 slides up and down within the limit seat 10. When the connecting rod 8 moves downward, it pushes the push rod 603, which in turn causes the piston plate 602 to move forward within the sleeve 601, compressing the air inside the sleeve 601. The compressed air is then ejected through the first hose 604 and the air blowing hole 201, promoting material flow and preventing blockage. When the connecting rod 8 rebounds upward, the spring 801 pulls the piston plate 602 back. At this time, the one-way valve in the second hose 605 opens, and external air supply gas enters the sleeve 601 to prepare for the next air supply cycle. The filter screen 102 in the air exchange hole filters out dust and impurities in the air, protecting the internal system from contamination.
[0052] Example 4
[0053] The collection device provided in the above embodiments is further optimized, specifically, as follows: Figure 4 As shown, the waste collection device also includes a first guide plate 11 fixedly installed inside the housing 1. The first guide plate 11 has a first funnel portion 1101 and a cylindrical portion 1102 for receiving waste that enters from the feed inlet and undergoes preliminary crushing. The grinding plate 2 is fixed to one end of the cylindrical portion 1102 away from the first funnel portion 1101, forming a relatively closed transition channel.
[0054] A spiral plate 12 is fixedly installed on the rotating shaft 4. The spiral plate 12 is located inside the cylindrical part 1102. As the rotating shaft 4 rotates, it generates spiral thrust, which pushes the material downward.
[0055] With the above structure, waste enters the box 1 from the feed inlet and is concentrated and introduced through the first funnel 1101. The design of the funnel ensures that the material will not deviate or get stuck and smoothly enters the cylindrical part 1102. The rotating shaft 4 drives the spiral plate 12 to rotate, forming a spiral thrust in the cylindrical part 1102. The material is gradually pushed to the inlet of the grinding chamber by the spiral plate 12, providing a stable supply for the subsequent crushing process.
[0056] Example 5
[0057] The collection device provided in the above embodiments is further optimized, specifically, as follows: Figure 4 As shown, the waste collection device also includes a second guide plate 13 fixedly installed inside the housing 1, which is used to receive the crushed material and guide it to the subsequent screening and leveling area. A scraper 14 is fixedly installed on the rotating shaft 4 and fits against the inner wall of the second guide plate 13. The scraper 14 rotates synchronously with the rotating shaft 4, continuously scraping off the waste particles attached to the inner wall of the guide plate to prevent material adhesion and blockage.
[0058] With the above-described structure, the rotating shaft 4 drives the scraper 14 to rotate. The edge of the scraper 14 is in close contact with the inner wall of the second guide plate 13. As it rotates, it continuously scrapes off the attached waste residue. The cleaned material re-enters the main process, avoiding waste and blockage risks.
[0059] The process of using the thermoplastic elastomer waste collection device provided by this utility model is as follows: The thermoplastic elastomer waste to be processed is put into the box 1 through the feed inlet 101. The waste first passes through the first funnel part 1101 of the first guide plate 11, and then enters the cylindrical part 1102. In the cylindrical part 1102, the spiral plate 12 rotates with the rotating shaft 4 to initially push and distribute the waste, preventing material accumulation or displacement. The waste is pushed by the spiral plate 12 into the crushing chamber between the grinding plate 2 and the grinding disc 5. The motor 3 drives the rotating shaft 4 to drive the grinding disc 5 to rotate at high speed. With the cooperation of the grinding plate 2, the waste is efficiently sheared and squeezed, crushing it into powder. Small particles are generated by the vibration of the vibrating disc 7 as the rotating shaft 4 rotates, which in turn pushes the piston part 6 through the connecting rod 8, causing the piston plate 602 to reciprocate within the sleeve 601. The piston part 6 supplies air to the air blowing hole 201 through the first hose 604, which helps the material fall smoothly and removes the residue on the surface of the grinding plate 2. The crushed waste is collected and introduced into the vibrating disc 7 through the second guide plate 13. The scraper 14 is fixed on the rotating shaft 4 and fits tightly against the inner wall of the second guide plate 13. As the rotating shaft 4 rotates, it continuously scrapes off the attached waste residue, ensuring smooth material flow. The vibrating disc 7 vibrates continuously under the drive of the rotating shaft 4, and the fine particles in the waste fall through the sieve hole 702 and are collected.
[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
