Description

Technical Field

[0001] This utility model relates to the field of injection molded part crushing technology, specifically to an injection molded part crushing and recycling device. Background Technology

[0002] Plastic injection molded parts are widely used in numerous industries. With the rapid increase in the consumption of plastic products, raw material resources are becoming increasingly scarce. Traditional injection molding production relies heavily on virgin plastics; mining and producing virgin plastics not only consumes a large amount of energy but also causes serious environmental damage. To alleviate resource pressure, there is an urgent need for equipment that can efficiently recycle waste injection molded parts, converting them back into reusable plastic pellets, achieving resource recycling, and reducing dependence on virgin plastics.

[0003] Injection molding production inevitably generates a large amount of waste injection molded parts, such as scraps and defective products. By equipping their production workshops with injection molded part crushing and recycling equipment, companies can promptly collect and crush these waste materials, reprocessing them into plastic granules that can be directly reused in injection molding production. This effectively reduces raw material costs and improves resource utilization. For example, toy manufacturers generate a large amount of injection molded toy scraps during production. After being processed by crushing and recycling equipment, these scraps can be reused in the injection molding of toy shells, reducing both costs and waste emissions.

[0004] Utility model application CN202323114988.8 relates to a self-recycling mixing injection molding device, comprising: an injection molding machine tool, a heating and feeding component, a crushing and self-suctioning component, and a discharge component; the heating and feeding component is fixedly connected to one side surface of the injection molding machine tool. The discharge component is fixedly connected to the other side surface of the injection molding machine tool; the crushing and self-suctioning component is provided on one side of the heating and feeding component. This utility model, through the crushing mechanism and the heating and feeding mechanism, can promptly throw the removed material head into the crushing box for crushing, and then use a vacuum negative pressure mechanism to pump it to the heating and feeding mechanism for heating and melting, and finally feed it into the injection molding machine tool for reprocessing, which can save materials and ensure processing quality.

[0005] The aforementioned patent uses heating and self-suction to allow the injection molding machine to reprocess the molded parts. However, it cannot clean and sort the plastic parts after crushing them, which leads to the need for additional cleaning processes during subsequent processing, reducing work efficiency.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this utility model is to provide an injection molded part crushing and recycling equipment that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0009] An injection molded part crushing and recycling device includes: a frame, a liquid separation assembly, and a recycling assembly;

[0010] The recycling assembly comprises a mounting shell, a storage plate, a screening plate, a placement plate, a fixed base, a rotating base, a threaded base, and a storage cavity. The mounting shell is fixedly connected to the storage plate, the storage plate is slidably connected to the screening plate, the screening plate is slidably connected to the placement plate, the fixed base is rotatably connected to the storage plate, the storage plate is rotatably connected to the rotating base, the rotating base is threadedly connected to the threaded base, and the storage cavity is fixedly connected to the threaded base.

[0011] Furthermore, the liquid separation assembly includes a base, a motor, a pump, a first channel, a second channel, a spray head, and a third channel; the base is fixedly connected to the motor, the motor is rotatably connected to the pump, the pump is connected to the first channel, the first channel is connected to the second channel, the second channel is fixedly connected to the spray head, and the spray head is connected to the third channel.

[0012] Furthermore, a control console is mounted on the side of the rack.

[0013] Furthermore, the screening plate has holes in the middle with a diameter smaller than that of the part being screened.

[0014] Compared with existing technologies, this utility model has the following beneficial effects: This utility model provides an injection molded part crushing and recycling device. The spray head can disperse liquid into fine droplets and spray them evenly onto a designated area. For example, during the cleaning process of injection molded parts, it can perform comprehensive and meticulous cleaning of the injection molded part surface.

[0022] like Figures 1 to 3 As shown, an injection molded part crushing and recycling device includes: a frame 1, a liquid separation component 2, and a recycling component 3.

[0023] The liquid distribution assembly 2 includes a base 21, a motor 22, a pump 23, a first channel 24, a second channel 25, a spray head 26, and a third channel 27. The base 21 is fixedly connected to the motor 22, and the motor 22 is rotatably connected to the pump 23. The pump 23 is connected to the first channel 24, the first channel 24 is connected to the second channel 25, the second channel 25 is fixedly connected to the spray head 26, and the spray head 26 is connected to the third channel 27. A control console 4 is installed on the side of the frame 1. After the motor 22 is started, its internal impeller rotates at high speed, creating a negative pressure in the pump chamber, thereby drawing liquid from an external liquid storage device (not shown in the figure, but its existence can be reasonably inferred) into the pump body. The output end of the motor 22 is rotatably connected to the pump 23. This connection method allows the pump 23 to be adjusted in angle within a certain range. The pump 23 is connected to the first channel 24, and the liquid enters the first channel 24 after the pump 23 adjusts the flow direction. The first channel 24 serves as the main delivery pipe, guiding the liquid to the second channel 25. The interconnected design between the first channel 24 and the second channel 25 ensures a smooth transition of the liquid. The second channel 25 is fixedly connected to the spray head 26. When the liquid flows through the second channel 25 and reaches the spray head 26, the special structure of the spray head 26 (including multiple small nozzles, atomizing devices, etc.) further processes the liquid.

[0024] As a supplement, the spray head 26 can disperse the liquid into fine droplets and spray it evenly onto a designated area. For example, during the cleaning of injection molded parts, it can perform comprehensive and meticulous cleaning of the injection molded parts surface. In other scenarios requiring precise spraying, the spray head 26 can spray the liquid at a specific angle and pressure to achieve precise liquid delivery to the target location. The spray head 26 is connected to the third channel 27, which provides a return path for unused or excess liquid.

[0025] Meanwhile, operators can input commands through the control console 4, such as controlling the start and stop of motor 22, adjusting the speed of motor 22 (and thus controlling the liquid flow rate), and adjusting the angle of pump 23 (changing the liquid flow direction). The control console 4 is equipped with a control system, which may include a microprocessor, controller, display screen, and operation buttons. The microprocessor is responsible for receiving commands input by the operator and sending control signals to relevant components according to preset programs and algorithms, thereby achieving automated and intelligent control of the liquid separation component 2 and meeting the precise control requirements of different production processes for the liquid separation process.

[0026] The recycling assembly 3 comprises a mounting shell 31, a storage plate 32, a screening plate 33, a placement plate 34, a fixed base 35, a rotating base 36, a threaded base 37, and a storage cavity 38. The mounting shell 31 is fixedly connected to the storage plate 32, the storage plate 32 is slidably connected to the screening plate 33, the screening plate 33 is slidably connected to the placement plate 34, the fixed base 35 is rotatably connected to the storage plate 32, the storage plate 32 is rotatably connected to the rotating base 36, the rotating base 36 is threadedly connected to the threaded base 37, and the storage cavity 38 is fixedly connected to the threaded base 37. The screening plate 33 has a hole in the middle with a diameter smaller than that of the part being screened. The threaded base 37 is manually driven to rotate. As the threaded base 37 rotates, the rotating base 36 begins to move along the thread direction, causing the storage plate 32 to rotate around the fixed base 35. The rotation of the storage plate 32 causes the screening plate 33 to tilt accordingly. Under the combined action of gravity and the tilt angle of the screening plate 33, the material begins to slide on the screening plate 33. During the sliding process, materials smaller than the diameter of the holes in the screening plate 33 fall through the holes and enter the storage chamber 38 for collection; while materials larger than the hole diameter remain on the screening plate 33 and continue to slide along the screening plate 33, eventually being conveyed to the placement plate 34. During the screening process, the tilt angle of the storage plate 32 can be adjusted by controlling the rotation direction and number of revolutions of the threaded base 37 according to the screening effect of the material and actual needs. For example, if it is found that the material slides too fast on the screening plate 33, resulting in insufficient screening, the tilt angle of the storage plate 32 can be appropriately reduced; conversely, if the material accumulates on the screening plate 33, affecting the screening efficiency, the tilt angle of the storage plate 32 can be increased. In this way, flexible control of the recycling and screening process can be achieved, ensuring that the recycling component 3 can adapt to the recycling needs of different materials and achieve the best recycling and screening effect.

[0027] Meanwhile, as a supplement: when the amount of fine materials in the storage chamber 38 reaches a certain level, the storage chamber 38 can be cleaned, and the collected materials can be further processed. Larger materials (such as parts) on the placement plate 34 can also be collected periodically for sorting, organization, or reuse in production. After cleaning, the recycling component 3 can continue with the next round of recycling and screening.

[0028] Working principle:

[0029] After the motor 22 starts, its internal impeller rotates at high speed, creating a negative pressure in the pump chamber, thereby drawing liquid from an external liquid storage device (not shown in the figure, but its existence can be reasonably inferred) into the pump body. The output end of the motor 22 is rotatably connected to the pump 23. This connection allows the pump 23 to be adjusted in angle within a certain range. The pump 23 is connected to the first channel 24. After the liquid is adjusted in direction by the pump 23, it enters the first channel 24. The first channel 24 serves as the main conveying pipe, guiding the liquid to the second channel 25. The threaded base 37 is manually driven to rotate. As the threaded base 37 rotates, the rotating seat 36 begins to move along the thread direction, causing the storage plate 32 to rotate around the fixed seat 35. The rotation of the storage plate 32 causes the screening plate 33 to tilt as well. Under the combined action of gravity and the tilt angle of the screening plate 33, the material begins to slide on the screening plate 33. During the sliding process, materials smaller than the diameter of the holes in the screening plate 33 fall through the holes and enter the storage chamber 38 for collection; while materials larger than the hole diameter remain on the screening plate 33 and continue to slide along it, eventually being conveyed to the placement plate 34. During the screening process, the tilt angle of the storage plate 32 can be adjusted by controlling the rotation direction and number of revolutions of the threaded base 37, according to the screening effect and actual needs. For example, if the material slides too fast on the screening plate 33, resulting in insufficient screening, the tilt angle of the storage plate 32 can be appropriately reduced; conversely, if the material accumulates on the screening plate 33, affecting the screening efficiency, the tilt angle of the storage plate 32 can be increased. In this way, flexible control of the recycling screening process is achieved, ensuring that the recycling component 3 can adapt to the recycling needs of different materials and achieve the best recycling screening effect.
