Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, and more specifically, to a vibration sorting device for plastic particles. Background Technology

[0002] Plastic granules typically refer to the base materials used in the production of plastic products. They are granules or particulate substances made from polymer resins. During production, plastic granules vary in size and are unevenly distributed, leading to differences in product quality. Using plastic granules directly in production would negatively impact product quality and reduce profitability. Therefore, machines are needed to separate plastic masterbatches of different sizes.

[0003] Currently, vibration sorting devices used for plastic particles can sort plastic particles, but they usually rely on multiple vibration motors to complete the vibration screening, which not only increases energy consumption but also wastes resources.

[0004] In addition, dust may accumulate during the screening process, causing plastic particles to get stuck in the mesh and unable to be shaken out by vibration. This reduces the effective opening area of ​​the mesh and thus affects the material separation effect of vibration sorting.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a vibration sorting device for plastic particles to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows: A vibration sorting device for plastic particles includes: a sorting box; a feeding port disposed on one side of the top of the sorting box; an air pump disposed in the middle of the top of the sorting box; a cleaning mechanism disposed at the bottom of the air pump and located at the top inner part of the sorting box for cleaning the inside of the sorting box; and a sorting mechanism disposed at the bottom of the cleaning mechanism and located in the middle inner part of the sorting box for vibration sorting of plastic particles.

[0008] Furthermore, in order to enable the nozzles to spray high-pressure air onto the sorting mechanism, blowing out dust or plastic particles from the first and second screening plates, ensuring that plastic particles are shaken out by vibration, increasing the effective opening area of ​​the mesh, and enhancing the efficiency of vibration sorting, the cleaning mechanism includes a motor located at the top and bottom of the sorting box. Connecting rods are provided on both sides of the motor, and the two sets of connecting rods are movably connected by a rectangular frame. A straight tube is provided inside the rectangular frame, and the straight tube has a hollow structure. The straight tube is movably connected to the rectangular frame by a connecting column. A hollow disk is provided at the bottom of the straight tube, and several nozzles are provided at the bottom of the hollow disk. The straight tube is movably connected to the motor by an eccentric rod, and a connecting pipe that cooperates with an air pump is provided on one side of the straight tube. The connecting pipe is a retractable flexible hose.

[0009] Furthermore, to enable the sorting mechanism to achieve multi-stage sorting of plastic particles through vibration using only a single drive source, successfully separating three different particle sizes, thus reducing energy consumption and improving the sorting efficiency of plastic particles, a control panel is provided at one end of the sorting box. A first collection trough cooperating with the sorting mechanism is provided on one side of the sorting box, and a second collection trough cooperating with the sorting mechanism is provided on the other side of the sorting box. A collection ramp cooperating with the sorting mechanism is provided at the bottom of the sorting box. The sorting mechanism includes a first screening plate cooperating with the first collection trough and a second screening plate cooperating with the second collection trough, arranged sequentially from top to bottom in the middle of the sorting box. A first screening plate and a second screening plate are connected by a vibration assembly that cooperates with the sorting box. The first screening plate and the second screening plate are staggered and inclined, and the aperture of the first screening plate is larger than that of the second screening plate. The vibration assembly includes a double-headed motor set at the top of the first screening plate. Cams are symmetrically arranged at both ends of the output shaft of the double-headed motor. A connecting rod is set on the side of the cam away from the double-headed motor. A fixed shaft is set on the side of the connecting rod away from the cam. A fixed seat that cooperates with the second screening plate is set on the outside of the fixed shaft. The vibration assembly also includes several support seats symmetrically arranged at the bottom of the sorting box and on both sides of the first screening plate and the second screening plate. A spring is set on one side of each support seat.

[0010] The beneficial effects of this utility model are as follows: 1) With the combined action of the sorting box, air pump, cleaning mechanism and sorting mechanism, the sorting mechanism can achieve multi-level sorting of plastic particles by vibration with only a single drive source, successfully separating three different sizes of particles. At the same time, the cleaning mechanism can clean the mesh to ensure that the plastic particles are shaken out by vibration. The combined action of the two not only reduces energy consumption, but also improves the sorting efficiency of plastic particles.

[0011] 2) With the combined action of the air pump and the cleaning mechanism, several nozzles can spray high-pressure air onto the sorting mechanism, which can blow out the dust or plastic particles on the first and second screening plates, ensuring that the plastic particles are shaken out by vibration, thereby increasing the effective opening area of ​​the mesh and enhancing the efficiency of vibration sorting.

[0016] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0017] According to an embodiment of the present invention, a vibration sorting device for plastic particles is provided.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the vibration sorting device for plastic particles according to an embodiment of the present invention includes: a sorting box 1; a feeding port 2, disposed on one side of the top of the sorting box 1; an air pump 3, disposed in the middle of the top of the sorting box 1; a cleaning mechanism 4, disposed at the bottom of the air pump 3 and located at the inner top of the sorting box 1, for cleaning the inside of the sorting box 1; and a sorting mechanism 5, disposed at the bottom of the cleaning mechanism 4 and located in the inner middle of the sorting box 1, for vibrating sorting of plastic particles.

[0019] With the help of the above technical solutions, this utility model, through the combined action of the sorting box 1, air pump 3, cleaning mechanism 4, and sorting mechanism 5, enables the sorting mechanism 5 to achieve multi-stage sorting of plastic particles through vibration using only a single drive source, successfully separating three different particle sizes. Simultaneously, the cleaning mechanism 4 cleans the mesh, ensuring that plastic particles are shaken out through vibration. The combined effect of these two mechanisms not only reduces energy consumption but also improves the sorting efficiency of plastic particles. The combined action of the air pump 3 and cleaning mechanism 4 allows several nozzles to spray high-pressure air onto the sorting mechanism, blowing out dust or plastic particles from the first and second screening plates, ensuring that plastic particles are shaken out through vibration. This increases the effective opening area of ​​the mesh and enhances the efficiency of vibration sorting. Furthermore, the combined action of the sorting box 1 and sorting mechanism 5 enables the sorting mechanism to achieve multi-stage sorting of plastic particles through vibration using only a single drive source, successfully separating three different particle sizes. This not only reduces energy consumption but also improves the sorting efficiency of plastic particles.

[0020] It should be explained that the air pump 3 is a device used to move or compress air. The air pump 3 increases the pressure or flow rate of air through the conversion of mechanical energy. The air pump 3 consists of a motor, pump body, inlet / outlet ports, pressure regulator, filter, and pipe joints. The motor provides power to drive the pump's operation. The pump body is the core part of the air pump, responsible for compressing and moving air. The inlet / outlet ports are used for air input and output, ensuring that air can enter the pump body, be compressed, and then discharged. The pressure regulator is used to control and regulate the air pressure. The filter is used to remove impurities from the air and prevent dust and particulate matter from entering the pump body. The pipe joints are used to connect the air pump to other equipment or systems so that air can be delivered to the target location. This is existing technology and will not be elaborated here.

[0021] Furthermore, the vibration sorting device for plastic particles of this invention can not only perform vibration sorting of plastic particles, but also adapt to other types of materials for vibration sorting by changing the parameters of the cleaning mechanism 4 and the sorting mechanism 5, thereby improving the efficiency and product quality of other types of materials in the vibration sorting process.

[0022] In one embodiment, the cleaning mechanism 4 includes a motor 401 located at the top and bottom of the sorting box 1. Connecting rods 402 are provided on both sides of the motor 401, and the two sets of connecting rods 402 are movably connected by a rectangular frame 403. A straight pipe 404 is provided inside the rectangular frame 403, and the straight pipe 404 has a hollow structure. The straight pipe 404 is movably connected to the rectangular frame 403 by a connecting column 405. A hollow disk 406 is provided at the bottom end of the straight pipe 404, and a [missing information - likely a design feature or feature] is provided at the bottom end of the hollow disk 406. Several nozzles 407; a straight pipe 404 is movably connected to the motor 401 via an eccentric rod 408, and a connecting pipe 409 cooperating with the air pump 3 is provided on one side of the straight pipe 404. The connecting pipe 409 is a retractable flexible hose, so that the several nozzles 407 can spray high-pressure air onto the sorting mechanism 5, which can blow out dust or plastic particles on the first screening plate 501 and the second screening plate 502, ensuring that the plastic particles are shaken out by vibration, thereby increasing the effective opening area of ​​the mesh and enhancing the efficiency of vibration sorting.

[0023] The working principle of the cleaning mechanism 4 is as follows: In the initial state, when the sorting mechanism 5 in the sorting box 1 stops working, under the control of the control panel 6, the operator controls and starts the motor 401. Under the rotation of the output shaft of the motor 401, the eccentric rod 408 rotates. Under the limiting action of the connecting rod 402 and the connection action of the connecting column 405, the rotation of the eccentric rod 408 causes the rectangular frame 403 to swing. At the same time, the rotation of the eccentric rod 408 causes the straight pipe 404 to move around the output shaft of the motor 401 in coordination with the rectangular frame 403, thereby driving the hollow disc. 406 and the straight pipe 404 rotate together around the output shaft of the motor 401. Under the control panel 6, the air pump 3 is controlled and started. Air is compressed from the air pump 3 and enters the connecting pipe 409, and enters the hollow disc 406 through the straight pipe 404. It is then sprayed through the nozzle 407. During the air compression and spraying process, the air impacts the first screening plate 501 and the second screening plate 502 in the sorting mechanism 5. Dust or plastic particles on the first screening plate 501 and the second screening plate 502 are blown out, which increases the effective opening area of ​​the mesh and enhances the efficiency of vibration sorting.

[0024] In one embodiment, for the sorting box 1 and the sorting mechanism 5, a control panel 6 is provided at one end of the sorting box 1, a first collection groove 7 that cooperates with the sorting mechanism 5 is provided on one side of the sorting box 1, a second collection groove 8 that cooperates with the sorting mechanism 5 is provided on the other side of the sorting box 1, and a collection ramp 9 that cooperates with the sorting mechanism 5 is provided at the bottom of the inner side of the sorting box 1.

[0025] In addition, to facilitate material discharge, both the first collecting trough 7 and the second collecting trough 8 have discharge ports at their bottoms (not shown in the figure). It should be noted that the collecting inclined plate 9 passes through the spring sheet 5037 and is connected to the inner wall of the sorting box 1, and the collecting inclined plate 9 and the spring sheet 5037 are provided with a sealing ring (not shown in the figure); to prevent material residue from remaining at the discharge port during discharge, a guide plate is provided between the discharge port of the collecting inclined plate 9 and the sorting box 1.

[0026] The sorting mechanism 5 includes a first screening plate 501 and a second screening plate 502 arranged sequentially from top to bottom in the middle of the sorting box 1 to cooperate with the first collection tank 7 and the second collection tank 8. The first screening plate 501 and the second screening plate 502 are connected by a vibration assembly 503 that cooperates with the sorting box 1. The first screening plate 501 and the second screening plate 502 are arranged at an alternating inclination, and the aperture of the first screening plate 501 is larger than the aperture of the second screening plate 502. The vibration assembly 503 includes a double-headed motor 5031 arranged at the top of the first screening plate 501. Cams 5032 are symmetrically arranged at both ends of the output shaft of the double-headed motor 5031. The cams 5032 are located away from the double-headed motor. A connecting rod 5033 is provided on one side of the machine 5031. A fixed shaft 5034 is provided on the side of the connecting rod 5033 away from the cam 5032. A fixed seat 5035 that cooperates with the second screening plate 502 is provided on the outer side of the fixed shaft 5034. The vibration assembly 503 also includes several support seats 5036 symmetrically arranged at the bottom of the sorting box 1 and on both sides of the first screening plate 501 and the second screening plate 502. A spring piece 5037 is provided on one side of each support seat 5036. Thus, the sorting mechanism can achieve multi-stage sorting of plastic particles by vibration with only a single drive source, successfully separating three different sizes of particles. This not only reduces energy consumption but also improves the sorting efficiency of plastic particles.

[0027] It should be explained that the 5037 spring is composed of composite materials such as carbon fiber or glass fiber reinforced plastic. These materials provide high elasticity and load-bearing capacity while being lightweight. This is existing technology and will not be elaborated here.

[0028] The working principle of the sorting box 1 and the sorting mechanism 5 is as follows: In the initial state, when plastic particles fall into the sorting box 1 from the feed port 2, the operator controls and starts the dual-head motor 5031 under the action of the control panel 6. Under the action of the output end of the dual-head motor 5031, the cam 5032 is driven to rotate. During the rotation of the cam 5032, the connecting rod 5033 is driven to move up and down. Under the action of the fixed shaft 5034 and the fixed seat 5035, the up and down movement of the connecting rod 5033 causes the second screening plate 502 to shake up and down. Under the action of the support seat 5036 and the spring piece 5037 at the bottom of the box, the second screening plate 502 shakes stably. Under the action of the support base 5036 and the spring piece 5037 of the second screening plate 502, the second screening plate 502 shakes, causing the first screening plate 501 to shake. During the shaking of the first screening plate 501 and the second screening plate 502, the plastic particles are screened. At the same time, the first screening plate 501 and the second screening plate 502 are placed at an alternating angle, and the aperture of the first screening plate 501 is larger than the aperture of the second screening plate 502. This allows plastic particles of the first size to enter the first collection tank 7, plastic particles of the second size to enter the second collection tank 8, and plastic particles of the third size to enter the collection inclined plate 9, thus realizing the vibration sorting of plastic particles of different sizes.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In practical application, initially, the operator pours plastic particles into the feed inlet 2. Under the control panel 6, the dual-head motor 5031 is started. The output shafts at both ends of the dual-head motor 5031 drive the first screening plate 501 and the second screening plate 502 to vibrate, simultaneously achieving vibration sorting of plastic particles of different sizes (the specific working principles of the sorting box 1 and the sorting mechanism 5 are described above). After sorting, the dual-head motor 5031 is stopped under the control panel 6, causing the first screening plate 501 and the second screening plate 502 to stop vibrating. Then, under the control... Under the control panel 6, the operator controls and starts the motor 401 and air pump 3. Under the action of the motor 401 and air pump 3, air is compressed from the air pump 3 into the connecting pipe 409, and then enters the hollow disc 406 through the straight pipe 404. It is then sprayed in multiple directions through the nozzle 407. The air compression and spraying process blows out the dust or plastic particles on the first screening plate 501 and the second screening plate 502, which increases the effective opening area of ​​the mesh and enhances the efficiency of vibration sorting. After cleaning, the motor 401 can be controlled and stopped under the control panel 6.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, under the combined action of the sorting box 1, air pump 3, cleaning mechanism 4, and sorting mechanism 5, the sorting mechanism 5 can achieve multi-stage sorting of plastic particles through vibration using only a single drive source, successfully separating three different particle sizes. Simultaneously, the cleaning mechanism 4 can clean the mesh, ensuring that plastic particles are shaken out through vibration. The combined effect of these two mechanisms not only reduces energy consumption but also improves the sorting efficiency of plastic particles. Under the combined action of the air pump 3 and the cleaning mechanism 4, several nozzles can spray high-pressure air onto the sorting mechanism, blowing out dust or plastic particles from the first and second screening plates, ensuring that plastic particles are shaken out through vibration, increasing the effective opening area of ​​the mesh, and enhancing the efficiency of vibration sorting. Under the combined action of the sorting box 1 and the sorting mechanism 5, the sorting mechanism can achieve multi-stage sorting of plastic particles through vibration using only a single drive source, successfully separating three different particle sizes, not only reducing energy consumption but also improving the sorting efficiency of plastic particles.
