Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite stabilizer production technology, specifically to a feeding device for PVC stabilizer production. Background Technology
[0002] PVC composite stabilizers are high-efficiency, multi-functional high-tech products developed and produced using scientific "molecular design" principles, advanced surface treatment technology, special composite processes, and a strict quality control system. They integrate heat stabilizers, internal and external lubricants, antioxidants, coupling agents, and dispersants. The production of PVC composite stabilizers requires feeding equipment. Traditional equipment still has some shortcomings in practical use. Existing feeding devices for PVC composite stabilizer production are prone to clogging the pipes when a large amount of raw material is added, affecting the feeding rate.
[0003] To address this technical problem, existing technology CN217594558U provides a feeding device for the production of PVC environmentally friendly composite stabilizers. By coordinating a placement plate, cylinder, push plate, control module, pressure plate, perforation, slide bar, receiving plate, compression spring, and distance sensor, the device can adjust the amount of material falling within the working frame, preventing blockage during composite stabilizer feeding and ensuring normal composite stabilizer feeding, thereby increasing the feeding rate of composite stabilizers.
[0004] However, certain technical issues may arise during its use. For example, the device requires a cylinder to drive a pusher plate, which then pushes the composite stabilizer accumulated on the receiving plate into the feeding pipe. However, during operation, the receiving plate moves up and down due to changes in the weight of the composite stabilizer, while the pusher plate remains at a fixed height. This can lead to situations where the pusher plate cannot completely push the composite stabilizer from the receiving plate into the feeding pipe, resulting in stabilizer residue on the receiving plate. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a feeding device for PVC stabilizer production that allows the pusher plate to remain pressed against the top of the receiving plate during use, thereby facilitating workers to push all the composite stabilizer accumulated on the receiving plate into the feeding pipe.
[0006] This utility model is achieved through the following technical solution: a feeding device for PVC stabilizer production is provided, including a working frame and a feeding pipe and a feeding tube respectively disposed at the top and bottom of the working frame. A pressure plate is fixedly connected to the inner side wall of the working frame. A limit rod is provided at the top of the pressure plate, extending downward vertically through the pressure plate. A receiving plate is provided directly below the feeding tube and fixedly connected to the top of the limit rod. The receiving plate is located on the side of the feeding tube facing the feeding tube. A pressure plate is provided on the side of the feeding tube away from the feeding tube. The push plate at the top of the material plate has a vertically extending groove on its side wall away from the feed pipe. A slider is installed in the groove. A cylinder is installed on the outer wall of the working frame. The piston rod end of the cylinder passes through the working frame and is fixedly connected to the side wall away from the feed pipe of the slider. A spring is sleeved on the limiting rod and fixedly connected to the pressure plate and the receiving plate respectively. A distance sensor is installed on the top of the pressure plate. The distance sensor is electrically connected to the cylinder through a controller. The end of the receiving plate away from the cylinder is located directly above the feed inlet of the feeding pipe.
[0007] In use, this utility model comprises a working frame and feeding pipes and discharge pipes respectively located at the top and bottom of the working frame. A pressure plate is fixedly connected to the inner side wall of the working frame, and a limit rod is provided at the top of the pressure plate, extending vertically downward through the pressure plate. A receiving plate is fixedly connected to the top of the limit rod directly below the feeding pipe, located on the side of the discharge pipe facing the feeding pipe. A push plate is provided on the side of the feeding pipe away from the discharge pipe, pressing against the top of the receiving plate. A sliding groove extending vertically is formed on the side wall of the push plate away from the feeding pipe, and a slider is provided in the groove. A cylinder is provided on the outer side wall of the working frame, and the end of the piston rod of the cylinder passes through the working frame and is fixedly connected to the side wall of the slider away from the feeding pipe. Springs, respectively fixed to the pressure plate and the receiving plate, are fitted on the positioning rod. A distance sensor is installed on the top of the pressure plate, which is electrically connected to the cylinder via a controller. The end of the receiving plate furthest from the cylinder is located directly above the feed inlet of the feeding pipe. During operation, the composite stabilizer must first be fed into the working frame through the feed pipe, allowing it to fall onto the receiving plate under gravity. As the weight on the receiving plate increases, it causes the limiting rod to move downwards within the pressure plate, compressing the springs. As the receiving plate moves downwards, the push plate, losing its upward support, also moves downwards under its own weight, causing the slider to move within the groove and press back onto the top of the receiving plate. When the receiving plate moves downwards to the preset value of the distance sensor, the distance sensor sends an electrical signal to the controller. The controller then sends an electrical signal to the cylinder, causing the piston rod to extend. This causes the push plate, driven by the slider and chute, to move towards the feeding pipe on the receiving plate. The push plate pushes the composite stabilizer accumulated on the receiving plate towards the feeding pipe, thus pushing the composite stabilizer into the feeding pipe. As the composite stabilizer accumulates on the receiving plate and enters the feeding pipe under the drive of the push plate, the weight on the receiving plate decreases, and the downward supporting force on the spring also decreases. The receiving plate then moves upwards under the drive of the spring. The push plate will also move upward under the drive of the receiving plate, and the slider will move in the chute. After all the composite stabilizer accumulated on the receiving plate has been pushed into the feeding pipe, the receiving plate returns to the initial position. When the receiving plate returns to the initial position, if the receiving plate has not reached the preset value of the distance sensor, the distance sensor will send an electrical signal to the controller. Then the controller sends an electrical signal to the cylinder, causing the piston rod of the cylinder to retract. This causes the push plate to move back to the initial position on the top of the receiving plate away from the feeding pipe under the transmission of the slider and the chute. This ensures that the push plate is always pressed against the top of the receiving plate when the device is in use, making it convenient for the operator to push all the composite stabilizer accumulated on the receiving plate into the feeding pipe.
[0008] Preferably, a counterweight block is provided inside the working frame and fixedly connected to the top of the push plate. By providing a counterweight block inside the working frame and fixedly connected to the top of the push plate, the stability of the push plate can be improved during use, ensuring that the push plate is always pressed against the top of the receiving plate.
[0009] Preferably, a shelf is fixed to the outer wall of the working frame, and the cylinder is fixedly mounted on the top of the shelf with bolts. By fixing the shelf to the outer wall of the working frame and fixing the cylinder to the top of the shelf with bolts, the stability of the cylinder during use can be improved.
[0010] Preferably, the lower end face of the pusher plate is configured as a downwardly convex arc shape. By configuring the lower end face of the pusher plate as a downwardly convex arc shape, it is easier for the pusher plate to move on top of the receiving plate, pushing the composite stabilizer accumulated on the receiving plate into the feeding pipe.
[0011] Preferably, the top of the receiving plate at the end away from the cylinder is tilted downwards. By tilting the top of the receiving plate at the end away from the cylinder downwards, it is easier for the operator to push the composite stabilizer accumulated on the receiving plate into the feeding pipe.
[0012] Preferably, a mounting plate is fixed to the outer wall of the feeding pipe, and a drive motor is bolted to the top of the mounting plate. The output shaft of the drive motor passes through the side wall of the feeding pipe and extends into the feeding pipe. A dispersing roller fixed to the output shaft of the drive motor is installed inside the feeding pipe. By fixing the mounting plate to the outer wall of the feeding pipe, and bolting the drive motor to the top of the mounting plate, with the output shaft of the drive motor passing through the side wall of the feeding pipe and extending into the feeding pipe, and a dispersing roller fixed to the output shaft of the drive motor installed inside the feeding pipe, the device, in use, rotates the output shaft of the drive motor by starting the drive motor on the mounting plate, causing the dispersing roller to rotate inside the feeding pipe. This prevents the composite stabilizer from clumping and clogging the feeding pipe when it enters the feeding pipe.
[0013] Preferably, two limiting rods are provided on the pressure plate, and the two limiting rods are laterally distributed along the left-right direction of the pressure plate. By providing two limiting rods on the pressure plate and distributing them laterally along the left-right direction of the pressure plate, the stability of the receiving plate during the up-and-down movement of the device can be improved.
[0014] Preferably, an anti-detachment block is provided below the pressure plate and fixedly connected to the bottom of the limiting rod. By providing an anti-detachment block below the pressure plate and fixedly connected to the bottom of the limiting rod, the anti-detachment block can be used to limit the range of motion of the limiting rod and prevent the limiting rod from falling off the pressure plate.
[0015] The beneficial effects of this utility model are as follows: A working frame is provided, along with a feeding pipe and a feeding tube respectively located at the top and bottom of the working frame. A pressure plate is fixedly connected to the inner wall of the working frame. A limit rod is provided at the top of the pressure plate, extending vertically downwards through the pressure plate. A receiving plate is provided directly below the feeding pipe, fixedly connected to the top of the limit rod. The receiving plate is located on the side of the feeding pipe facing the feeding pipe. A push plate is provided on the side of the feeding pipe away from the feeding pipe, pressing against the top of the receiving plate. A vertically extending groove is opened on the side wall of the push plate away from the feeding pipe, and a slider is provided in the groove. A cylinder is provided on the outer wall of the working frame. The piston rod end of the cylinder passes through the working frame and is fixedly connected to the side wall of the slider away from the feeding pipe. Springs, respectively fixed to the pressure plate and the receiving plate, are fitted on the positioning rod. A distance sensor is installed on the top of the pressure plate, which is electrically connected to the cylinder via a controller. The end of the receiving plate furthest from the cylinder is located directly above the feed inlet of the feeding pipe. During operation, the composite stabilizer must first be fed into the working frame through the feed pipe, allowing it to fall onto the receiving plate under gravity. As the weight on the receiving plate increases, it causes the limiting rod to move downwards within the pressure plate, compressing the springs. As the receiving plate moves downwards, the push plate, losing its upward support, also moves downwards under its own weight, causing the slider to move within the groove and press back onto the top of the receiving plate. When the receiving plate moves downwards to the preset value of the distance sensor, the distance sensor sends an electrical signal to the controller. The controller then sends an electrical signal to the cylinder, causing the piston rod to extend. This causes the push plate, driven by the slider and chute, to move towards the feeding pipe on the receiving plate. The push plate pushes the composite stabilizer accumulated on the receiving plate towards the feeding pipe, thus pushing the composite stabilizer into the feeding pipe. As the composite stabilizer accumulates on the receiving plate and enters the feeding pipe under the drive of the push plate, the weight on the receiving plate decreases, and the downward supporting force on the spring also decreases. The receiving plate then moves upwards under the drive of the spring. The push plate will also move upward under the drive of the receiving plate, and the slider will move in the chute. After all the composite stabilizer accumulated on the receiving plate has been pushed into the feeding pipe, the receiving plate returns to the initial position. When the receiving plate returns to the initial position, if the receiving plate has not reached the preset value of the distance sensor, the distance sensor will send an electrical signal to the controller. Then the controller sends an electrical signal to the cylinder, causing the piston rod of the cylinder to retract. This causes the push plate to move back to the initial position on the top of the receiving plate away from the feeding pipe under the transmission of the slider and the chute. This ensures that the push plate is always pressed against the top of the receiving plate when the device is in use, making it convenient for the operator to push all the composite stabilizer accumulated on the receiving plate into the feeding pipe.

[0023] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0024] like Figures 1-5 The present invention discloses a feeding device for PVC stabilizer production, comprising a working frame 5 and a feeding pipe 1 and a feeding pipe 6 respectively disposed at the top and bottom of the working frame 5. A pressure plate 19 is fixedly connected to the inner wall of the working frame 5. A limiting rod 12 is disposed at the top of the pressure plate 19, extending vertically downwards through the pressure plate 19. A receiving plate 11 is disposed directly below the feeding pipe 1 and fixedly connected to the top of the limiting rod 12. The receiving plate 11 is located on the side of the feeding pipe 6 facing the feeding pipe 1. A push plate 10 is disposed on the side of the feeding pipe 1 away from the feeding pipe 6, pressing against the top of the receiving plate 11. A vertically extending groove 17 is provided on the side wall of the push plate 10 away from the feed pipe 1. A slider 18 is provided in the groove 17. A cylinder 2 is provided on the outer side wall of the working frame 5. The piston rod end of the cylinder 2 passes through the working frame 5 and is fixedly connected to the side wall of the slider 18 away from the feed pipe 1. A spring 14 is sleeved on the limiting rod 12 and fixedly connected to the pressure plate 19 and the receiving plate 11 respectively. A distance sensor 13 is installed on the top of the pressure plate 19. The distance sensor 13 is electrically connected to the cylinder 2 through the controller 4. The end of the receiving plate 11 away from the cylinder 2 is located directly above the feed inlet of the feeding pipe 6.
[0025] By installing a counterweight 9 fixedly connected to the top of the push plate 10 within the working frame 5, the stability of the push plate 10 during use is improved, ensuring that the push plate 10 always presses against the top of the receiving plate 11. A placement plate 3 is fixedly connected to the outer wall of the working frame 5, and the cylinder 2 is bolted to the top of the placement plate 3, further enhancing the stability of the cylinder 2 during use. By designing the lower end face of the push plate 10 as a downward-convex arc, it facilitates movement of the push plate 10 on top of the receiving plate 11, pushing the composite stabilizer accumulated on the receiving plate 11 into the feeding pipe 6. By tilting the top of the receiving plate 11 away from the cylinder 2 downwards, it is easier for operators to push the composite stabilizer accumulated on the receiving plate 11 into the feeding pipe 6. An installation plate 8 is fixed to the outer wall of the feeding pipe 6. A drive motor 7 is bolted to the top of the installation plate 8. The output shaft of the drive motor 7 passes through the side wall of the feeding pipe 6 and extends into the feeding pipe 6. A dispersing roller 16 is installed inside the feeding pipe 6 and fixed to the output shaft of the drive motor 7. When the device is in use, the drive motor 7 on the installation plate 8 is started, causing the output shaft of the drive motor 7 to rotate, which drives the dispersing roller 16 to rotate inside the feeding pipe 6. This prevents the composite stabilizer from clumping and clogging the feeding pipe 6 when it enters the feeding pipe 6. Two limiting rods 12 are provided on the pressure plate 19, and the two limiting rods 12 are laterally distributed along the left and right directions of the pressure plate 19. This improves the stability of the receiving plate 11 during the up and down movement of the device during use. By providing an anti-detachment block 15 below the pressure plate 19 and fixing it to the bottom of the limiting rod 12, the anti-detachment block 15 can be used to limit the range of motion of the limiting rod 12 and prevent the limiting rod 12 from falling off the pressure plate 19.
[0026] Combined with appendix Figure 1-5The method of using this utility model is as follows: First, the composite stabilizer needs to be fed into the working frame 5 through the feed pipe 1, so that the composite stabilizer falls onto the receiving plate 11 under the action of gravity. When the weight on the receiving plate 11 increases, the receiving plate 11 will drive the limiting rod 12 to move downward within the pressure plate 19 and compress the spring 14. When the receiving plate 11 moves downward, the push plate 10 loses its upward support force and will move downward with the receiving plate 11 under its own weight and the weight of the counterweight 9, and cause the slider 18 to move within the slide groove 17 and press back onto the top of the receiving plate 11. When the receiving plate 11 moves downward to the preset value of the distance sensor 13, Distance sensor 13 sends an electrical signal to controller 4, which then sends an electrical signal to cylinder 2 on the placement plate 3, causing the piston rod of cylinder 2 to extend. This causes push plate 10, driven by slider 18 and slide groove 17, to move on receiving plate 11 toward feeding pipe 6. Push plate 10 pushes the composite stabilizer accumulated on receiving plate 11 toward feeding pipe 6, thus pushing the composite stabilizer accumulated on receiving plate 11 into feeding pipe 6. As the composite stabilizer accumulated on receiving plate 11 enters feeding pipe 6 under the drive of push plate 10, the weight on receiving plate 11 continuously decreases, and the downward supporting force on spring 14 also continuously decreases. Driven by spring 14, plate 11 moves upward continuously. As plate 11 moves upward, push plate 10 also moves upward, causing slider 18 to move within groove 17. Once all the composite stabilizer accumulated on plate 11 is pushed into feed pipe 6, plate 11 returns to its initial position. If plate 11 does not reach the preset value of distance sensor 13 after returning to its initial position, distance sensor 13 sends an electrical signal to controller 4. Controller 4 then sends an electrical signal to cylinder 2, causing the piston rod of cylinder 2 to retract. This causes push plate 10, driven by slider 18 and groove 17, to move upward from the top of plate 11 towards the distance... As the push plate 10 moves back to its initial horizontal position from the direction of the feeding pipe 6, it remains pressed against the top of the receiving plate 11 under its own weight and the weight of the counterweight 9. Therefore, the push plate 10 will also return to its initial vertical position under the upward supporting force of the receiving plate 11. During the process of the worker feeding material into the feeding pipe 6 through the device, the drive motor 7 on the mounting plate 8 is started, causing the output shaft of the drive motor 7 to rotate and drive the dispersing roller 16 to rotate inside the feeding pipe 6. This prevents the composite stabilizer from clumping and blocking the feeding pipe 6 when it enters the feeding pipe 6.
