Description

Technical Field

[0001] This invention belongs to the field of plastic recycling technology, specifically a plastic parts recycling and processing device. Background Technology

[0002] With the continuous growth in the consumption of plastic products, millions of tons of waste plastic are generated globally every year. Traditional landfill or incineration methods can easily cause soil pollution and greenhouse gas emissions. In recent years, mechanical recycling has become the mainstream due to its low cost and low pollution. However, existing equipment generally suffers from bottlenecks such as low sorting purity, high energy consumption, and poor performance of recycled materials. In the injection molding process, issues such as material and process parameters, mold design and cleaning, equipment and operation factors, environmental and raw material factors, and insufficient testing and process control can all lead to defects in the appearance or structure of injection molded parts, resulting in defective products. Therefore, it is necessary to use a recycling and processing device to recycle plastic parts.

[0003] CN106493876A discloses a recycling and processing device and method for large plastic parts, including a fixed support, a drying tank, a vacuum pump, a hot melt pelletizing device, and a storage tank. The fixed support has an opening in the middle, and the drying tank has connecting bosses on both sides. The drying tank is mounted on the opening of the fixed support through the connecting bosses on both sides. The connecting bosses are connected to the fixed support by fastening bolts. The hot melt pelletizing device is located at the bottom of the drying tank, and the storage tank is connected below the drying tank. The drying tank and the storage tank are connected to each other on the outside of the connection point by fastening bolts. A vacuum pump is connected to one side of the drying tank and is placed on the fixed support. This device saves energy, has low noise, produces regular granules after crushing, and occupies a small area.

[0004] However, when using this device, it can only recycle and process large plastic parts, and it cannot classify and crush defective injection molded parts of different sizes. When large and small injection molded parts are crushed together, the large materials require a longer time and a higher speed to be crushed to the target size, while the small materials may be over-crushed into powder in a short time, resulting in different sizes of recycled parts, which in turn affects the subsequent process and requires screening.

[0008] Preferably, the partitions are arranged in several groups, and the partitions are distributed at equal intervals about the central axis of the conveyor belt. The conveyor belt is externally meshed with the second drive shaft, and the rotating end of the first servo motor is fixed with the second drive shaft.

[0009] Preferably, an extension rod is fixed to the outside of the first connecting rod, and two sets of torsion springs and extension rods are provided. The torsion springs and extension rods are symmetrically distributed about the central axis of the first connecting rod. One end of the torsion spring is fixed to the outside of the conveyor frame. The conveyor frame is used to compress the first connecting rod and keep it rotating upward.

[0010] Preferably, a third screening hole is provided at the bottom of the screening plate, a dust removal fan is fixed inside the screening plate, the bottom of the screening plate is set as an inclined surface, the diameter of the first screening hole is smaller than the diameter of the second screening hole, and the diameter of the second screening hole is smaller than the diameter of the third screening hole.

[0011] Preferably, the crushing mechanism includes a support frame, a second servo motor, and a second connecting rod. The support frame is located at the bottom inside the processing frame. The second servo motor is fixed to the outside of the support frame. The second connecting rod is fixed to the rotating end of the second servo motor. A first crushing disc is fixed to the outside of the second connecting rod. A third servo motor is fixed to the outside of the support frame. A third connecting rod is fixed to the rotating end of the third servo motor. A second crushing disc is fixed to the outside of the third connecting rod. A baffle is fixed inside the support frame.

[0012] Preferably, the second connecting rod and the processing frame are rotatably connected, the first crushing disc is provided with several sets of equally spaced components about the central axis of the second connecting rod, and the third connecting rod and the processing frame are rotatably connected.

[0013] Preferably, the vibration mechanism includes an eccentric wheel, a limiting box, and a first pressure rod. The eccentric wheel is fixed to the outside of the second connecting rod, the limiting box is fixed to the outside of the processing frame, the first pressure rod is movably connected inside the limiting box, a return spring is sleeved on the outside of the first pressure rod, and a second pressure rod is fixed to the top of the first pressure rod.

[0014] Preferably, two sets of eccentric wheels are provided, the eccentric wheels are fixed to the outside of the third connecting rod, the outer wall of the first pressure rod is in contact with the inner wall of the limiting box, and the first pressure rod and the limiting box are slidably connected.

[0015] Preferably, a limit box is fixed to the top end of the return spring, and a first pressure rod is fixed to the bottom end of the return spring. The return spring is used to squeeze the first pressure rod and keep it moving downward. Two sets of the second pressure rod are provided.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated arrangement of a first connecting rod, a guide plate, and a screening plate, enables the device to press an extension rod via a second pressure rod. This extension rod causes the first connecting rod and the guide plate to rotate, causing the injection molded parts conveyed to the top of the guide plate to rotate downwards. After the second pressure rod disengages from the extension rod, a torsion spring, through its restoring force, resets the first connecting rod and the guide plate, causing the injection molded parts falling onto the guide plate to vibrate. This effectively separates injection molded parts of different sizes that are stuck together. Furthermore, once the injection molded parts are inside the screening plate, they pass through the inclined surface at the bottom of the screening plate, sequentially passing through the first screening hole, the second screening hole, and the third screening hole. This separates the injection molded parts into three categories from small to large, allowing them to fall into the guide box at the bottom for guidance. This achieves the purpose of facilitating the separation of injection molded parts of different sizes that are stuck together through dual vibration.

[0017] This invention, through the coordinated arrangement of a support frame, a second servo motor, and a second connecting rod, enables the device to divide the support frame into three crushing zones via baffles, ensuring that these zones do not interfere with each other. Activating the second and third servo motors drives the second connecting rod, the first crushing disc, the third connecting rod, and the second crushing disc to rotate, thus classifying, crushing, and recycling the internal injection molded parts. This achieves the goal of facilitating the separate crushing and recycling of injection molded parts of three different sizes.

[0018] This invention, through the coordinated arrangement of an eccentric wheel, a limiting box, and a first pressure rod, enables the device to synchronously drive the eccentric wheel to rotate when the second connecting rod rotates. The eccentric wheel, in turn, presses against the first pressure rod during rotation, causing both the first and second pressure rods to move upwards. The first pressure rod then presses against the screening plate, and the second pressure rod presses against the extension rod. After the eccentric wheel disengages from the first pressure rod, a return spring resets the first pressure rod, and this process is repeated. This continuous pressing and disengaging of the first pressure rod from the screening plate, combined with the fact that the thickness of the connection between the screening rod and the movable hole of the processing frame is less than the thickness of the movable hole, causes the screening plate to vibrate after being pressed upwards and disengaged. This vibration of the screening plate allows for more effective screening of the injection-molded parts inside, thereby improving the screening efficiency of the device for injection-molded parts of different sizes.

[0021] like Figures 1 to 8 As shown, the present invention provides a plastic parts recycling and processing device, including a processing frame 1, a conveying mechanism 2 fixed at the top of the processing frame 1, a storage box 3 provided at one end of the conveying mechanism 2, a guiding mechanism 4 installed at one end of the conveying mechanism 2, a screening mechanism 5 movably connected inside the processing frame 1, a guide box 6 fixed inside the processing frame 1, three sets of guide grooves opened at the bottom of the guide box 6, a crushing mechanism 7 provided at the bottom of the guide box 6, and a vibration mechanism 8 installed at one end of the crushing mechanism 7.

[0022] like Figures 1 to 8 As shown, the conveying mechanism 2 includes a conveying frame 201, a first drive shaft 202, and a conveyor belt 203. The conveying frame 201 is fixed to the top of the processing frame 1. The first drive shaft 202 is rotatably connected inside the conveying frame 201. The conveyor belt 203 is meshed with the outside of the first drive shaft 202. A partition 204 is fixed to the outside of the conveyor belt 203. A second drive shaft 205 is rotatably connected inside the conveying frame 201. A first servo motor 206 is fixed to the outside of the conveying frame 201. The bottom end of the conveying frame 201 is located inside the storage box 3. Several sets of partitions 204 are provided. The partitions 204 are evenly distributed about the central axis of the conveyor belt 203. The conveyor belt 203 is meshed with the outside of the second drive shaft 205. The rotating end of the first servo motor 206 is fixed to the second drive shaft 205.

[0023] The above scheme is adopted: by starting the first servo motor 206 to drive the second transmission shaft 205 to rotate, thereby driving the conveyor belt 203 to move and driving the first transmission shaft 202 to rotate, so that when the conveyor belt 203 moves, the partition plate 204 at the top of the conveyor belt 203 moves synchronously with the conveyor belt 203, thereby conveying the injection molded parts inside the storage box 3, so that they fall into the screening plate 501 for screening after being guided by the guide plate 402.

[0024] like Figures 1 to 6 As shown, the guiding mechanism 4 includes a first connecting rod 401, a guide plate 402, and a torsion spring 403. The first connecting rod 401 is rotatably connected inside the conveying frame 201. The guide plate 402 is fixed to the outside of the first connecting rod 401. The torsion spring 403 is fixed to the outside of the first connecting rod 401. An extension rod 404 is fixed to the outside of the first connecting rod 401. Two sets of torsion springs 403 and extension rods 404 are provided. The torsion springs 403 and extension rods 404 are symmetrically distributed about the central axis of the first connecting rod 401. One end of the torsion spring 403 is fixed to the outside of the conveying frame 201. The conveying frame 201 is used to squeeze the first connecting rod 401 and keep it rotating upward.

[0025] The above solution is adopted: the second pressure rod 805 presses the extension rod 404, causing the extension rod 404 to drive the first connecting rod 401 and the guide plate 402 to rotate, causing the injection molded part conveyed to the top of the guide plate 402 to rotate downward. After the second pressure rod 805 disengages from the extension rod 404, the torsion spring 403 resets the first connecting rod 401 and the guide plate 402 through its own restoring force, causing the injection molded part falling on the guide plate 402 to vibrate, thereby separating the injection molded parts of different sizes that are stuck together in advance.

[0026] like Figures 1 to 7 As shown, the screening mechanism 5 includes a screening plate 501, a first screening hole 502, and a second screening hole 503. The screening plate 501 is movably connected inside the processing frame 1. The bottom of the screening plate 501 has a first screening hole 502, a second screening hole 503, and a third screening hole 504. A dust collector fan 505 is fixed inside the screening plate 501. The bottom of the screening plate 501 is set as an inclined surface. The diameter of the first screening hole 502 is smaller than the diameter of the second screening hole 503, and the diameter of the second screening hole 503 is smaller than the diameter of the third screening hole 504.

[0027] Using the above scheme: After the injection molded parts are located inside the screening plate 501, they pass through the inclined surface at the bottom of the screening plate 501, and sequentially pass through the first screening hole 502, the second screening hole 503, and the third screening hole 504. This allows the injection molded parts to be divided into three categories from small to large and fall into the bottom guide box 6 for guidance, so that they can enter the processing end of the support frame 701. Furthermore, by activating the dust removal fan 505 to blow air into the bottom of the screening plate 501, when the small injection molded parts that are stuck on the large injection molded parts are detached by vibration in the area where the large injection molded parts are put in, the air blown by the dust removal fan 505 can push the small injection molded parts back because the weight of the small injection molded parts is less than that of the large injection molded parts, thus keeping the position of the large injection molded parts unchanged.

[0028] like Figures 1 to 4 As shown, the crushing mechanism 7 includes a support frame 701, a second servo motor 702, and a second connecting rod 703. The support frame 701 is located at the bottom inside the processing frame 1. The second servo motor 702 is fixed to the outside of the support frame 701. The second connecting rod 703 is fixed to the rotating end of the second servo motor 702. A first crushing disc 704 is fixed to the outside of the second connecting rod 703. A third servo motor 705 is fixed to the outside of the support frame 701. A third connecting rod 706 is fixed to the rotating end of the third servo motor 705. A second crushing disc 707 is fixed to the outside of the third connecting rod 706. A baffle 708 is fixed inside the support frame 701. The second connecting rod 703 is rotatably connected to the processing frame 1. The first crushing disc 704 has several sets of components evenly distributed about the central axis of the second connecting rod 703. The third connecting rod 706 is rotatably connected to the processing frame 1.

[0029] The above solution is adopted: the support frame 701 is divided into three crushing zones by the baffle 708 so that they will not affect each other. The second servo motor 702 and the third servo motor 705 are started to drive the second connecting rod 703, the first crushing disc 704 and the third connecting rod 706, and the second crushing disc 707 to rotate, so that they can classify, crush and recycle the internal injection molded parts.

[0030] like Figures 1 to 8As shown, the vibration mechanism 8 includes an eccentric wheel 801, a limiting box 802, and a first pressure rod 803. The eccentric wheel 801 is fixed to the outside of the second connecting rod 703. The limiting box 802 is fixed to the outside of the processing frame 1. The first pressure rod 803 is movably connected inside the limiting box 802. Two sets of eccentric wheels 801 are provided. The eccentric wheels 801 are fixed to the outside of the third connecting rod 706. The outer wall of the first pressure rod 803 is attached to the inner wall of the limiting box 802. The first pressure rod 803 and the limiting box 802 are slidably connected. A return spring 804 is sleeved on the outside of the first pressure rod 803. A second pressure rod 805 is fixed to the top of the first pressure rod 803. The limiting box 802 is fixed to the top of the return spring 804. The first pressure rod 803 is fixed to the bottom of the return spring 804. The return spring 804 is used to squeeze the first pressure rod 803 and keep it moving downward. Two sets of second pressure rods 805 are provided.

[0031] The above scheme is adopted as follows: When the second connecting rod 703 rotates, it synchronously drives the eccentric wheel 801 to rotate. Then, when the eccentric wheel 801 rotates, it squeezes the first pressure rod 803, causing the first pressure rod 803 and the second pressure rod 805 to move upward as a whole. Then, the first pressure rod 803 squeezes the screening plate 501 and the second pressure rod 805 squeezes the extension rod 404. After the eccentric wheel 801 disengages from the first pressure rod 803, the return spring 804 resets the first pressure rod 803 and repeats this action, so that the first pressure rod 803 continuously squeezes and disengages from the screening plate 501, and simultaneously the second pressure rod 805 squeezes and disengages from the extension rod 404. Since the thickness of the connection between the screening rod 501 and the movable hole of the processing frame 1 is less than the thickness of the movable hole, the screening plate 501 vibrates after being squeezed and disengaged upward. Then, the vibration of the screening plate 501 can more effectively screen the injection molded parts inside the screening plate 501.

[0032] The working principle and usage process of this invention are as follows: The first servo motor 206 is activated, driving the second transmission shaft 205 to rotate, which in turn moves the conveyor belt 203 and drives the first transmission shaft 202 to rotate. As the conveyor belt 203 moves, the partition plate 204 at the top of the conveyor belt 203 moves synchronously with it, thereby conveying the injection molded parts inside the storage box 3. After being guided by the guide plate 402, the parts fall into the screening plate 501 for screening. The second pressure rod 805 presses the extension rod 404, causing the extension rod 404 to drive the first connecting rod 401 and the guide plate 402 to rotate, thus conveying the parts to the guide plate 402. The top injection molded part rotates downwards, and after the second pressure rod 805 disengages from the extension rod 404, the torsion spring 403 resets the first connecting rod 401 and the guide plate 402 through its own restoring force. This causes the injection molded part falling on the guide plate 402 to vibrate, thereby separating the injection molded parts of different sizes that are stuck together in advance. After the injection molded parts are located inside the screening plate 501, they pass through the inclined surface at the bottom of the screening plate 501, and sequentially pass through the first screening hole 502, the second screening hole 503, and the third screening hole 504. This separates the injection molded parts into three categories from small to large, and they fall into the guide box 6 at the bottom for guidance, allowing them to enter the support frame 701. Inside the processing end, the support frame 701 is divided into three crushing zones by a baffle 708 to prevent them from affecting each other. The second servo motor 702 and the third servo motor 705 are activated, driving the second connecting rod 703, the first crushing disc 704, the third connecting rod 706, and the second crushing disc 707 to rotate. This allows for the sorting, crushing, and recycling of the internal injection molded parts. The rotation of the second connecting rod 703 synchronously drives the eccentric wheel 801 to rotate, which in turn squeezes the first pressure rod 803, causing the first pressure rod 803 and the second pressure rod 805 to move upwards as a whole. The first pressure rod 803 then squeezes the screening plate. The first pressure rod 803 is reset by the return spring 804 after the eccentric wheel 801 disengages from the first pressure rod 803, and this action is repeated, so that the first pressure rod 803 continuously presses and disengages from the screening plate 501, and simultaneously the second pressure rod 805 presses and disengages from the extension rod 404. Since the thickness of the connection between the screening rod 501 and the movable hole of the processing frame 1 is less than the thickness of the movable hole, the screening plate 501 vibrates after being pressed upward and disengaged, and then the vibration of the screening plate 501 is used to more effectively screen the injection molded parts inside the screening plate 501.
