Description

Technical Field

[0001] This utility model relates to the field of waste plastic reprocessing technology, specifically to a plastic parts processing waste separation device with vibration screening. Background Technology

[0002] Currently, "waste plastic" is a common term and does not refer to discarded, old, or useless plastic products. Most plastic products, especially those used in large quantities for single purposes, do not undergo significant changes in the properties of the plastic material itself after use. Therefore, they can be recycled and reprocessed into plastic products for reuse. Waste plastic is a general term for plastics used in civilian and industrial applications that have been eventually phased out or replaced. To avoid environmental pollution from these waste plastics, they are recycled and reprocessed, saving resources and reducing environmental pollution. However, waste plastics often contain impurities during recycling and processing, necessitating screening. A search revealed a vibrating screening machine for waste plastic reprocessing, disclosed in Chinese patent CN220242099U. This machine includes a main body with a feed hopper fixedly connected to it. A fixed plate is fixedly connected to the feed hopper, and a first motor is fixedly mounted on the fixed plate. The output end of the first motor is fixedly connected to an auger via a connecting sleeve. This invention, by incorporating components such as a screen, a turntable, and a connecting rod, allows plastic to be placed on the screen. A second motor is then activated, driving the turntable to rotate. This causes the screen to slide within the vibrating screening machine, thus vibrating and screening the plastic. This solves the problem of waste plastics containing impurities requiring manual screening, which is time-consuming and labor-intensive.

[0003] However, in actual use, because the drive mechanism is located on top of the screen, if too much waste accumulates on the top surface of the screen, it will hinder the swing of the connecting rod in the drive mechanism, thus affecting the normal vibration screening of the screen. Utility Model Content

[0004] To address the problem of existing separation equipment being easily affected by material accumulation, this invention provides a plastic parts processing waste separation device with vibration screening.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A plastic parts processing waste separation device with vibration screening includes a separation box and a top-connected feed hopper. Vertical grooves are respectively opened on both sides of the inner wall of the separation box. A screen plate is slidably connected between the two vertical grooves. A baffle is installed on one side of the bottom surface of the screen plate. A drive mechanism is provided inside the baffle of the screen plate. The drive mechanism includes an eccentric wheel and a connecting rod. The connecting rod is hinged to the inner bottom surface of the screen plate. The bottom end of the connecting rod is rotatably connected to one side of the edge of the eccentric wheel. The eccentric wheel is rotatably connected to one side of the inner wall of the separation box.

[0007] Furthermore, a housing is installed on one side of the outer wall of the separation box, and a first shaft is rotatably connected inside the housing. One end of the first shaft extends into the interior of the separation box and is fitted and connected to the center position of the eccentric wheel.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the chassis provides installation and protection space for the first shaft. One end of the first shaft extends into the separation box and is connected to the eccentric wheel assembly, which can stably transmit the power from outside the chassis to the eccentric wheel, ensuring that the rotation of the eccentric wheel drives the screen plate to vibrate.

[0009] Furthermore, a motor for driving the first shaft to rotate is installed on one side of the outer wall of the chassis.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the installation and use of the motor enables it to provide power for the rotation of the first shaft.

[0011] Furthermore, the top surface of the chassis is provided with a transmission mechanism, which includes a housing. The inner sides of the housing are respectively connected to a driven synchronous pulley and a driving synchronous pulley. The outer walls of the driven synchronous pulley and the driving synchronous pulley are fitted with synchronous belts and are connected by synchronous belt transmission.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, through the power transmission of the driven synchronous pulley, the driving synchronous pulley and the synchronous belt, it is convenient to transmit the power output of the motor to the loosening component, so that the stirring shaft in the loosening component can rotate.

[0013] Furthermore, the feed hopper is equipped with a loosening component, and a second shaft is fitted at one end of the driven synchronous wheel to drive the movement of the loosening component.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the loosening component can pre-break up the clumps of waste material, avoid large pieces of waste material from clogging the feed hopper or screen plate, and ensure smooth feeding.

[0015] Furthermore, the loosening component includes a horizontal frame and a stirring shaft. The horizontal frame is installed on the inner wall of the feed hopper. The second shaft and the stirring shaft rotate on the inner sides of the horizontal frame respectively, and the bottom end of the stirring shaft extends into the interior of the feed hopper. A second bevel gear is fitted at one end of the second shaft, and a first bevel gear is fitted at one end of the stirring shaft. The first bevel gear meshes with the second bevel gear.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the cross frame provides installation support for the second shaft and the stirring shaft, ensuring that the two rotate stably in the feed hopper; when the second shaft rotates, the stirring shaft is driven to rotate through the meshing transmission of the second bevel gear and the first bevel gear. The stirring shaft extends into the inside of the feed hopper to fully contact the waste material, and the rotating blades break up the clumps of waste material, ensuring that the waste particles fall evenly.

[0017] Furthermore, baffles for blocking the vertical grooves are respectively installed on both sides of the top surface of the sieve plate.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the baffle can block the vertical trough, preventing waste from leaking out from the gaps in the vertical trough during the screening process, and at the same time, it also prevents waste from getting stuck inside the vertical trough.

[0019] Furthermore, a discharge port is provided on one side of the outer wall of the separation box, and a box door is hinged inside the discharge port.

[0020] The advantages of adopting the above-mentioned further solution are that the discharge port makes it easy to remove the separated waste material, the hinged box door can be opened and closed flexibly, and the separation box is kept sealed when closed to prevent dust from leaking out during the screening process.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This type of vibrating screen for separating plastic parts processing waste utilizes the coordinated use of vertical troughs, screen plates, baffles, eccentric wheels, and connecting rods to ensure smooth screening operations and effectively reduce waste obstruction. The separation chamber provides a closed processing space for waste separation, preventing waste from splashing and polluting the environment during screening. The feed hopper facilitates the centralized loading of plastic parts processing waste, ensuring accurate entry into the separation chamber. Vertical troughs on both sides of the inner wall provide sliding tracks for the screen plate, restricting its vibration to a vertical direction to separate waste of different particle sizes, achieving waste grading. The baffles on the bottom of the screen plate protect the drive mechanism, preventing waste from falling into the mechanism and causing jamming, ensuring stable operation of the drive components. Simultaneously, the eccentric wheel of the drive mechanism is positioned at the bottom of the screen plate, causing it to vibrate up and down via the connecting rod during rotation, effectively preventing contact with accumulated waste and ensuring smooth screening operations.

[0029] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: a plastic parts processing waste separation device with vibration screening, including a separation box 1 and a top-connected feed hopper 2. The separation box 1 provides a closed processing space for waste separation, preventing waste from splashing and polluting the environment during screening. The feed hopper 2 facilitates the centralized feeding of plastic parts processing waste, ensuring that the waste enters the separation box accurately. Vertical grooves 15 are respectively opened on both sides of the inner wall of the separation box 1. A screen plate 10 is slidably connected between the two vertical grooves 15. The vertical grooves 15 provide a sliding track for the screen plate 10, restricting the screen plate 10 to vibrate only in the vertical direction, separating waste of different particle sizes, and realizing waste grading. A baffle 11 is installed on one side of the bottom surface of the screen plate 10. A drive mechanism is provided inside the baffle 11 of the screen plate 10. The drive mechanism includes an eccentric wheel 13 and a connecting wheel 14. The rod 12 is hinged to the inner bottom surface of the screen plate 10. The bottom end of the connecting rod 12 is rotatably connected to one side of the edge of the eccentric wheel 13. The eccentric wheel 13 is rotatably connected to one side of the inner wall of the separation box 1. The baffle 11 on the bottom surface of the screen plate provides protection for the drive mechanism, preventing waste from falling into the mechanism and causing jamming, and ensuring stable operation of the drive components. At the same time, the eccentric wheel 13 of the drive mechanism is set at the bottom of the screen plate 10, so that when it rotates, it drives the screen plate to vibrate up and down through the connecting rod 12. This can effectively prevent contact with the accumulated waste, thereby ensuring smooth screening. The top surfaces of the screen plate 10 are respectively equipped with baffles 14 for blocking the vertical groove 15. The baffles 14 can block the vertical groove 15 to prevent waste from leaking out from the gap of the vertical groove 15 during the screening process. At the same time, it also prevents waste from getting stuck inside the vertical groove 15.

[0031] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] As one embodiment of this utility model, further, a housing 6 is installed on one side of the outer wall of the separation box 1. A first shaft 8 is rotatably connected inside the housing 6. One end of the first shaft 8 extends into the interior of the separation box 1 and is fitted with the center of the eccentric wheel 13. The housing 6 provides installation and protection space for the first shaft 8. The fact that one end of the first shaft 8 extends into the separation box and is fitted with the eccentric wheel 13 allows for stable transmission of external power to the eccentric wheel 13, ensuring that the rotation of the eccentric wheel 13 drives the screen plate 10 to vibrate. A motor 7 for driving the rotation of the first shaft 8 is installed on one side of the outer wall of the housing 6. The installation and use of motor 7 provides power for the rotation of the first shaft 8. The top surface of the housing 6 is provided with a transmission mechanism 4, which includes a housing 401. The driven synchronous pulley 402 and the driving synchronous pulley 403 are respectively connected to the two sides inside the housing 401. The outer walls of the driven synchronous pulley 402 and the driving synchronous pulley 403 are fitted with synchronous belts 404 and are connected by transmission through the synchronous belts 404. Through the power transmission of the driven synchronous pulley 402, the driving synchronous pulley 403 and the synchronous belts 404, the power output of motor 7 is easily transmitted to the loosening component 3, so that the stirring shaft 304 in the loosening component 3 can rotate.

[0033] As an embodiment of this utility model, further, the inside of the feed hopper 2 is provided with a loosening component 3. One end of the driven synchronous wheel 402 is fitted with a second shaft 9 for driving the movement of the loosening component 3. The loosening component 3 can pre-break up clumps of waste material to prevent large pieces of waste material from clogging the feed hopper or screen plate, ensuring smooth feeding. The loosening component 3 includes a horizontal frame 301 and a stirring shaft 304. The horizontal frame 301 is installed on the inner wall of the feed hopper 2. The second shaft 9 and the stirring shaft 304 rotate on the inner sides of the horizontal frame 301 respectively, and the bottom end of the stirring shaft 304 extends into the inside of the feed hopper 2. One end of the shaft 9 is fitted with a second bevel gear 303, and one end of the stirring shaft 304 is fitted with a first bevel gear 302. The first bevel gear 302 meshes with the second bevel gear 303. The cross frame 301 provides mounting support for the second shaft 9 and the stirring shaft 304, ensuring that the two rotate stably in the feed hopper. When the second shaft rotates, the stirring shaft 304 is driven to rotate through the meshing transmission of the second bevel gear 303 and the first bevel gear 302. The stirring shaft extends into the feed hopper to fully contact the waste material. The rotating blades break up the clumps of waste material, ensuring that the waste particles fall evenly.

[0034] As an embodiment of this utility model, a discharge port is further provided on one side of the outer wall of the separation box 1. A box door 5 is hinged inside the discharge port. The discharge port facilitates the removal of the separated waste material. The hinged box door 5 can be opened and closed flexibly. When closed, it maintains the sealing of the separation box and prevents dust from leaking out during the screening process.

[0035] Specifically, the working principle of this type of plastic parts processing waste separation equipment with vibration screening is as follows: When in use, the motor 7 on the outer wall of the machine box 6 is started first. The output end of the motor drives the first shaft 8 inside the machine box to rotate. On one hand, one end of the first shaft extends into the separation box 1, driving the eccentric wheel 13 connected in a set to rotate. The eccentric wheel pulls the screen plate 10 up and down along the vertical grooves 15 on both sides of the inner wall of the separation box through the connecting rod 12 connected by the edge rotation. The baffles 14 on both sides of the top surface of the screen plate block the vertical grooves to prevent waste from leaking out or getting stuck in the gaps. At the same time, the baffle 11 on the bottom surface of the screen plate protects the drive mechanism from the interference of waste and ensures the stability of vibration screening. On the other hand, the first shaft drives the active synchronous wheel 403 in the outer shell 401 of the transmission mechanism 4 to rotate. The active synchronous wheel drives the driven synchronous wheel 402 to rotate through the synchronous belt 404. The driven synchronous wheel transmits power to the loosening component 3 in the feed hopper 2 through the second shaft 9. At this point, waste plastic parts processing is fed into the feed hopper. The second shaft of the loosening component drives the second bevel gear 303 to rotate. Through meshing with the first bevel gear 302, it drives the stirring shaft 304 to rotate under the support of the cross frame 301. The blades of the stirring shaft extending into the feed hopper break up the clumps of waste, ensuring that the waste particles fall evenly onto the screen plate in the separation box. The screen plate screens the waste by vibrating up and down. Large-diameter waste particles remain on the surface of the screen plate, while small-diameter waste particles fall through the screen holes to the bottom of the separation box. After screening, the hinged door 5 of the discharge port on the outer wall of the separation box is opened, and the large-particle waste on the surface of the screen plate and the small-particle waste at the bottom of the box are removed respectively, completing the graded separation and recycling of waste plastic parts processing.
