Description

Technical Field

[0001] This disclosure relates to the field of sorting machine technology, specifically to a fully automatic electrostatic sorting machine for mixed plastics. Background Technology

[0002] A sorting machine is a device used to classify, grade, and separate materials. It is widely used in various industries, especially in mining, metallurgy, chemical, food processing, and recycling. Its main function is to sort materials based on certain characteristics (such as particle size, density, shape, magnetism, color difference, etc.), so that different categories of materials can be effectively separated and processed.

[0003] According to a public disclosure, a fully automatic electrostatic separator for mixed plastics (publication number: CN 219190883 U) includes a housing. Inside the housing, a partition divides the housing into a feeding box and a sorting box. The feeding box is positioned above the sorting box and has a feed inlet for easy material pouring. Inside the feeding box, from top to bottom, are a buffer mechanism for material feeding and a screw conveyor mechanism. The sorting box contains an electrostatic sorting mechanism, and a drying mechanism is located on one side of the feeding box. This disclosure, by providing a buffer mechanism at the top of the feeding box, slows the falling speed of the mixed plastics, ensuring they fall slowly into the screw conveyor mechanism. By starting the feeding motor, the first screw conveyor rotates, feeding the mixed plastics into the feeding funnel, preventing accumulation of mixed plastics during feeding and improving sorting efficiency.

[0004] The components such as the box, partition, and feed port in the above application work together to prevent the accumulation of mixed plastics during the feeding process, but they cannot achieve automatic discharge. Therefore, we propose a fully automatic electrostatic sorting machine for mixed plastics. Utility Model Content

[0005] This disclosure proposes a fully automatic electrostatic sorting machine for mixed plastics, which solves the problem of the inability to achieve automatic discharge in related technologies.

[0006] According to one aspect, at least one embodiment of this disclosure provides a fully automatic electrostatic sorting machine for mixed plastics, comprising: a sorting box, wherein a corona discharge device is fixedly connected to the inner side wall of the sorting box, and a material pushing and discharging device is provided on the inner side wall of the sorting box;

[0007] The material pushing and discharging device includes a motor, the bottom of which is fixedly connected to the inner side of the distribution box. A threaded rod is fixedly connected to the motor's output shaft, and a threaded sleeve is threaded onto the circumference of the threaded rod. A connecting rod is fixedly connected to the side of the threaded sleeve, and a push plate is fixedly connected to one end of the connecting rod. A limit rod is fixedly connected to the inner side of the distribution box, and an opening is provided on the side of the distribution box. This material pushing and discharging device is designed to achieve efficient and stable material pushing and distribution by using a motor to provide power, a threaded transmission mechanism for precise control, and a connecting rod and push plate to push the material to the opening. The limit rod ensures that the push plate's movement is within a suitable range, preventing unnecessary damage to the equipment. The opening provides a channel for smooth material discharge. Overall, this device provides an efficient, adjustable, and reliable material pushing and distribution mechanism, ensuring a smooth and accurate material distribution process.

[0008] For example, in at least one embodiment of this disclosure, a fully automatic electrostatic sorting machine for mixed plastics is provided, further comprising: a sliding connection between the circumferential surface of the threaded sleeve and the circumferential surface of the limiting rod. This sliding connection design helps improve the reliability, accuracy, and lifespan of the mechanical system, while also providing necessary limiting and protection functions.

[0009] A rotating shaft is rotatably connected to the side of the opening. This shaft allows for adjustment of the opening angle, thereby controlling the outflow of material. This design provides flexibility and adjustability in material discharge, while also helping to prevent material leakage and improving the operational efficiency and safety of the equipment.

[0010] A cover plate is fixedly connected to the circumferential surface of the rotating shaft. The cover plate is mainly used to provide protection, sealing, stability and support, ensuring the normal operation of the rotating shaft, extending its service life, and also helping to improve the structural stability and appearance of the equipment.

[0011] The side of the cover plate lies on the displacement trajectory of the pusher plate. The main function of this cover plate is to protect and guide the smooth movement of the pusher plate, prevent material leakage, reduce wear, and enhance the stability of the entire system. This design ensures the efficient operation of the pusher plate and prevents unnecessary damage or interference.

[0012] A return torsion spring is fixedly connected to the circumferential surface of the rotating shaft, with one end of the return torsion spring fixedly connected to the side of the opening. The return torsion spring, connected to both the rotating shaft and the side of the opening, primarily provides a restoring force to return the rotating shaft to its predetermined position, stabilizing the system, mitigating impacts and vibrations, controlling the range of motion of the rotating shaft, and improving the overall efficiency and stability of the system. It plays a crucial role in ensuring the normal operation of the mechanical movement and improving durability.

[0013] The opening has a flow-guiding ramp on its side, and there is a gap between the top of the push plate and the bottom of the corona discharge device. The main functions of the flow-guiding ramp on the side of the opening and the gap between the top of the push plate and the bottom of the corona discharge device are to optimize airflow or material flow, ensure the normal operation of the corona discharge device, prevent dust or contaminant interference, reduce resistance, and improve the stability and efficiency of the device. These designs help the system maintain a highly efficient and stable operating state and enhance the reliability of the equipment.

[0014] According to another aspect, at least one embodiment of this disclosure also provides a fully automatic electrostatic sorting machine for mixed plastics, comprising: an automatic feeding device disposed on the top of the push plate, the automatic feeding device including a push rod, one end of the push rod being fixedly connected to the top of the push plate; a discharge port being opened on the side of the distribution box; a hopper being slidably connected to the side of the distribution box; a sliding plate being slidably connected to the side of the discharge port; and a force-bearing plate being fixedly connected to the side of the sliding plate. The sliding plate is connected to the discharge port to control the flow of materials and regulate the material flow rate. The sliding connection of the sliding plate can adjust the opening degree of the discharge port, thereby controlling the rate of material outflow. The force-bearing plate is connected to the sliding plate to withstand external forces and adjust the movement of the sliding plate. Its function is to ensure the stability of the sliding plate and effectively control the flow of materials by providing support or force, thereby achieving the effect of automated feeding, improving work efficiency, reducing labor, and realizing the automation of the equipment.

[0015] For example, in at least one embodiment of this disclosure, a fully automatic electrostatic sorting machine for mixed plastics further includes: the side of the force-bearing plate is located on the displacement trajectory of the push rod, and a support leg is fixedly connected to the bottom of the hopper. The function of the force-bearing plate and the support leg is to ensure the stability, durability, and safety of the mechanical equipment during operation, while also ensuring the coordination between different components and the reasonable distribution of forces.

[0016] A return spring is fixedly connected to the side of the sliding plate, and one end of the return spring is fixedly connected to the inner side of the distribution box. The initial state of the return spring is a taut state. The return spring mainly functions to automatically restore the position of the sliding plate after it is affected by external force, adjust the discharge flow rate, improve equipment reliability, and ensure normal operation. Through this design, the system can maintain stability and reduce equipment failures caused by improper human operation or external factors.

[0017] The working principle and beneficial effects of this disclosure are as follows:

[0018] 1. This disclosure achieves a highly efficient, adjustable, and reliable material pushing and distribution mechanism by cooperating with components such as a motor, threaded rod, threaded sleeve, limiting rod, and push plate. Starting the motor drives the threaded rod to rotate, which in turn causes the threaded sleeve to move horizontally under the constraint of the limiting rod. This horizontal movement of the threaded sleeve drives the connecting rod to move horizontally, which in turn drives the push plate to move horizontally. The push plate then pushes the material that has undergone corona discharge to the opening, pushing the cover plate to rotate and push it out via a rotating shaft. This ensures a smooth and precise material distribution process.

[0019] 2. This disclosure utilizes the coordinated operation of components such as a motor, threaded rod, threaded sleeve, push plate, and sliding plate to achieve automated feeding, improve work efficiency, reduce labor, and automate the equipment. Starting the motor drives the threaded rod to rotate, which in turn causes the threaded sleeve to move horizontally under the constraint of a limiting rod. This horizontal movement of the threaded sleeve drives the connecting rod to move horizontally, which in turn drives the push plate to move horizontally. The push plate then drives the push rod to move horizontally, which in turn drives the force plate to move horizontally. This horizontal movement of the push rod then drives the sliding plate to move horizontally, exposing the discharge port. The material flows through the discharge port into the distribution box for electrostatic sorting, thus achieving automated feeding, improving work efficiency, reducing labor, and automating the equipment.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5 As shown, it illustrates a fully automatic electrostatic sorting machine for mixed plastics in one embodiment of the present disclosure, including: a sorting box 1, a corona discharge device 2 fixedly connected to the inner side wall of the sorting box 1, and a material pushing and discharging device 3 provided on the inner side wall of the sorting box 1.

[0032] The material pushing and discharging device 3 includes a motor 31, the bottom of which is fixedly connected to the inner side of the distribution box 1. A threaded rod 32 is fixedly connected to the output shaft of the motor 31. A threaded sleeve 33 is threadedly connected to the circumferential surface of the threaded rod 32. A connecting rod 34 is fixedly connected to the side of the threaded sleeve 33. A push plate 35 is fixedly connected to one end of the connecting rod 34. A limit rod 311 is fixedly connected to the inner side of the distribution box 1, and an opening 36 is provided on the side of the distribution box 1. This material pushing and discharging device 3 is designed to provide power through the motor 31, achieve precise control through a threaded transmission mechanism, and push the material to the opening 36 through the connecting rod 34 and the push plate 35, thereby achieving efficient and stable material pushing and distribution. The limit rod 311 ensures that the movement of the push plate 35 is within a suitable range, avoiding unnecessary damage to the equipment. The opening 36 provides a channel for the smooth discharge of materials. Overall, this device provides an efficient, adjustable, and reliable material pushing and distribution mechanism, ensuring a smooth and accurate material distribution process.

[0033] In some examples, the circumferential surface of the threaded sleeve 33 is slidably connected to the circumferential surface of the limiting rod 311. This sliding connection design helps improve the reliability, accuracy, and lifespan of the mechanical system, while also providing necessary limiting and protection functions.

[0034] A rotating shaft 37 is rotatably connected to the side of the opening 36. The rotating shaft 37, connected to the side of the opening 36, allows for adjustment of the angle of the opening 36, thereby controlling the outflow of material. This design provides flexibility and adjustability in material discharge, while also helping to prevent material leakage and improving the operating efficiency and safety of the equipment.

[0035] A cover plate 38 is fixedly connected to the circumferential surface of the rotating shaft 37. The cover plate 38 fixedly connected to the circumferential surface of the rotating shaft 37 is mainly to provide protection, sealing, stability and support, to ensure the normal operation of the rotating shaft 37 and extend its service life, and also to help improve the structural stability and appearance of the equipment.

[0036] The side of the cover plate 38 lies on the displacement trajectory of the push plate 35. The main function of the cover plate 38 is to protect and guide the smooth movement of the push plate 35, prevent material leakage, reduce wear, and enhance the stability of the entire system. This design ensures the efficient operation of the push plate 35 and prevents unnecessary damage or interference.

[0037] A return torsion spring 39 is fixedly connected to the circumferential surface of the rotating shaft 37, with one end of the return torsion spring 39 fixedly connected to the side of the opening 36. The return torsion spring 39, connected to both the rotating shaft 37 and the side of the opening 36, primarily provides a restoring force to return the rotating shaft 37 to its predetermined position, stabilizing the system, mitigating impacts and vibrations, controlling the range of motion of the rotating shaft 37, and improving the overall efficiency and stability of the system. It plays a crucial role in ensuring the normal operation of the mechanical movement and improving durability.

[0038] A flow-guiding ramp 310 is provided on the side of the opening 36, and there is a gap between the top of the push plate 35 and the bottom of the corona discharge device 2. The main function of the flow-guiding ramp 310 on the side of the opening 36 and the gap between the top of the push plate 35 and the bottom of the corona discharge device 2 is to optimize airflow or material flow, ensure the normal operation of the corona discharge device 2, prevent dust or contaminant interference, reduce resistance, and improve the stability and efficiency of the equipment. These designs help the system maintain a high-efficiency and stable working state and enhance the reliability of the equipment.

[0039] For example, such as Figures 1-5 As shown, the motor 31 is started, and the motor 31 drives the threaded rod 32 to rotate. The rotation of the threaded rod 32 causes the threaded sleeve 33 to move horizontally under the restriction of the limit rod 311. The horizontal movement of the threaded sleeve 33 causes the connecting rod 34 to move horizontally. The horizontal movement of the connecting rod 34 causes the push plate 35 to move horizontally. The horizontal movement of the push plate 35 pushes the material that has completed corona discharge to the opening 36, pushing the cover plate 38 to rotate and push it out through the rotating shaft 37. When the cover plate 38 loses its pushing force, the reset torsion spring 39 drives the rotating shaft 37 to reset and rotate through its own torque. The reset rotation of the rotating shaft 37 drives the cover plate 38 to rotate and reset.

[0040] like Figures 1-5As shown, this illustrates a fully automatic electrostatic sorting machine for mixed plastics in another embodiment of this disclosure. The technical solution is largely the same as that of Embodiment 1, so only the differences are described in detail. These differences include: an automatic feeding device 4 is provided on the top of the push plate 35, the automatic feeding device 4 includes a push rod 41, one end of which is fixedly connected to the top of the push plate 35; a discharge port 42 is provided on the side of the distribution box 1; a hopper 43 is slidably connected to the side of the distribution box 1; a sliding plate 44 is slidably connected to the side of the discharge port 42; and a force-bearing plate 45 is fixedly connected to the side of the sliding plate 44. The sliding plate 44 is connected to the discharge port 42 to control the flow of material and adjust the material flow rate. The sliding connection of the sliding plate 44 can adjust the opening degree of the discharge port 42, thereby controlling the rate of material outflow. The force-bearing plate 45 is connected to the sliding plate 44 to withstand external forces and adjust the movement of the sliding plate 44. Its function is to provide support or force to ensure the stability of the sliding plate 44 and effectively control the flow of materials, thereby achieving automated feeding, improving work efficiency, reducing labor, and realizing equipment automation.

[0041] In some examples, the force plate 45 is positioned on the displacement trajectory of the push rod 41, and a support leg 46 is fixedly connected to the bottom of the hopper 43. The force plate 45 and the support leg 46 serve to ensure the stability, durability, and safety of the mechanical equipment during operation, while also ensuring coordination between different components and the reasonable distribution of forces.

[0042] A return spring 47 is fixedly connected to the side of the sliding plate 44. One end of the return spring 47 is fixedly connected to the inner side of the distribution box 1. The initial state of the return spring 47 is taut. The return spring 47 mainly functions to automatically restore the position of the sliding plate 44 after it is affected by external force, thereby adjusting the discharge flow rate, improving equipment reliability, and ensuring normal operation. Through this design, the system can maintain stability and reduce equipment failures caused by improper human operation or external factors.

[0043] For example, such as Figures 1-5 As shown, the motor 31 is started, and the motor 31 drives the threaded rod 32 to rotate. The rotation of the threaded rod 32 causes the threaded sleeve 33 to move horizontally under the restriction of the limiting rod 311. The horizontal movement of the threaded sleeve 33 causes the connecting rod 34 to move horizontally. The horizontal movement of the connecting rod 34 causes the push plate 35 to move horizontally. The horizontal movement of the push plate 35 causes the push rod 41 to move horizontally. The horizontal movement of the push rod 41 pushes the force plate 45 to move horizontally. The horizontal movement of the push rod 41 causes the sliding plate 44 to move horizontally. The horizontal movement of the sliding plate 44 exposes the discharge port 42. The material flows into the distribution box 1 through the discharge port 42 for electrostatic separation. When the force plate 45 loses its pushing force, the reset spring 47 pushes the sliding plate 44 to return to its horizontal position through its own elasticity.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
