Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymer particle conveying technology, specifically a quantitative conveying device for polymer particle raw materials. Background Technology
[0002] A quantitative conveying device for polymer granules is used to convey granular polymer materials to a predetermined precise quantity. It is widely used in many industrial fields such as plastics processing, rubber product manufacturing, and chemical synthesis. The device typically consists of a storage silo, a feeding mechanism, a metering device, and a conveying pipeline. During operation, the material enters the conveying pipeline or channel at a set rate. During the conveying process, the metering device measures the amount of material conveyed in real time and feeds the data back to the control system. The control system compares the data from the metering device with the preset quantitative value and adjusts the operating parameters of the feeding mechanism to precisely control the amount of material conveyed, ensuring that the set quantitative requirement is met, and ultimately delivering the accurate quantity of material to the target location.
[0003] For example, Chinese patent CN213976010U, entitled "A Feeding and Conveying Device for Manufacturing Polymer Particles Using Recycled Resources," includes a main support and an adjusting device. A conveyor belt is rotatably connected to the surface of the main support. The adjusting device includes two fixed rods, both fixedly connected to the surface of the main support. A baffle is fixedly connected to the end of each fixed rod away from the main support. Two limiting plates are fixedly connected to the surfaces of the two baffles that are close to each other. A rectangular plate is slidably connected to the side of the two limiting plates that are close to each other. A fixing block is fixedly connected to the surface of the rectangular plate near the baffle. A rod is slidably inserted into the surface of the fixing block. A fixing ring is fixedly connected to the side wall of the rod near the baffle. A first spring is sleeved on the surface of the rod. One end of the first spring is fixedly connected to the fixing ring, and the end of the first spring away from the fixing ring is fixedly connected to the fixing block. Positioning holes are evenly distributed on the surface of the baffle, the size of which is adapted to the size of the rod. A rotating shaft is rotatably connected to the surface of the rectangular plate.
[0004] While the existing technologies can achieve the conveying of raw materials, in practical use, on the one hand, it is difficult to remove the moisture inside the raw materials. Usually, the raw materials contain a certain amount of moisture, which leads to defects such as holes and cracks in the products during subsequent operations. On the other hand, the vibration generated by the conveying device can easily affect the weighing component. Usually, the weighing component is directly fixed to the conveying device, which means that the vibration generated when the motor is working is directly transmitted to the weighing component, thereby increasing the risk of damage to the weighing component. Therefore, it does not meet the current needs. In response, we propose a quantitative conveying device for polymer particle raw materials. Utility Model Content
[0005] The purpose of this invention is to provide a quantitative conveying device for polymer particle raw materials, in order to solve the problems mentioned in the background art, such as the difficulty in removing moisture from the raw materials and the easy impact of vibration generated by the conveying device on the symmetrical weighting components.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitative conveying device for polymer granular raw materials, including a conveying platform, a storage tank disposed above one side of the conveying platform, the upper end of the storage tank having an open structure, a lid disposed at the upper end of the storage tank, the lid being connected to the storage tank by a snap-fit, a stirring frame disposed at the lower end of the lid, the stirring frame being rotatably connected to the lid, a heating wire fixedly disposed inside the side wall of the storage tank, the heating wire being distributed in a spiral structure, a second motor fixedly disposed at the center position of the upper end of the lid, the output shaft of the second motor extending to the lower part of the lid and fixedly connected to the stirring frame, and an exhaust pipe fixedly disposed at the upper end of the lid located on the side of the second motor, the exhaust pipe being connected to the storage tank.
[0007] Preferably, a connecting seat is fixedly provided at both the front and rear ends of the upper part of the storage tank, a damper is fixedly provided at the lower end of the connecting seat, and a support spring is fixedly provided at both the fixed end and the telescopic end of the damper.
[0008] Preferably, a weighing component is fixedly installed at the lower end of the damper fixed end, and a mounting plate is fixedly installed at the lower end of the weighing component, with the lower end of the mounting plate fixedly connected to the conveyor table.
[0009] Preferably, a discharge pipe is fixedly installed at the center of the lower end of the storage tank, the discharge pipe is connected to the storage tank, and a valve is fixedly installed on the outside of the discharge pipe.
[0010] Preferably, a conveying cavity is provided at the middle position inside the conveying platform. The conveying cavity has a through structure. Several rotating rods are provided inside the conveying cavity. The rotating rods are evenly distributed. The front and rear ends of the rotating rods are rotatably connected to the inner wall of the conveying cavity. A belt roller is fixedly provided outside the rotating rod. A conveyor belt is sleeved on the outside of the belt roller.
[0011] Preferably, a first motor is fixedly installed at the front and rear ends of both sides of the outer side of the conveyor platform. The output shaft of the first motor extends into the interior of the conveying cavity and is fixedly connected to the rotating rod. Support rods are fixedly installed at the four corners of the lower end of the conveyor platform.
[0012] Preferably, the front and rear ends of the conveyor belt are provided with anti-leakage strips, and the anti-leakage strips and the conveyor belt are an integrated structure.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model can dry and stir raw materials by means of a stirring rack and a heating wire. When processing raw materials, the heating wire is energized first. The heating wire itself has a certain resistance. When the current passes through the heating wire, the heating wire will generate heat. The heat generated by the heating wire is transferred to the inside of the storage tank through the side wall of the storage tank, which raises the temperature of the raw materials inside the storage tank until the raw materials are heated to a suitable temperature, thereby accelerating the evaporation of moisture in the raw materials. At the same time, the second motor is turned on, so that the output shaft of the second motor drives the stirring rack to rotate. The rotation of the stirring rack stirs the raw materials inside the storage tank, so that the raw materials can be heated evenly.
[0015] (2) This utility model can absorb the vibration generated by the second motor through the damper and the support spring. When the raw material is processed, the second motor is in working state. The rotation of the rotor inside the second motor will generate a certain vibration. The vibration is transmitted to the connecting seat through the storage tank. At this time, the connecting seat will squeeze the damper and the support spring. The damper and the support spring will deform after being squeezed. The vibration on the connecting seat is absorbed by the deformation of the damper and the support spring, avoiding the vibration from being directly transmitted to the weighing component, thereby extending the service life of the weighing component.
[0016] (3) This utility model can quantitatively transport raw materials by setting up a weighing component. When it is necessary to discharge the material, the drying of the raw material has been completed and the second motor and heating wire have been turned off. At this time, the operator records the overall weight data of the raw material and the storage tank, opens the valve, and allows the raw material to be discharged from the storage tank through the discharge pipe. At the same time, the weight data gradually decreases, and the operator monitors the changes in the weight data in real time until the appropriate discharge amount is reached. At this time, the valve is closed and the operator records the weight data again, thereby improving the accuracy of raw material discharge. Attached Figure Description

[0023] Please see Figure 1-4 This utility model provides an embodiment of a quantitative conveying device for polymer granular raw materials, including a conveying platform 1, a discharge pipe 20 fixedly installed at the center of the lower end of a storage tank 13, the discharge pipe 20 being connected to the storage tank 13, a valve 19 fixedly installed on the outside of the discharge pipe 20, a conveying chamber 4 located at the center of the inside of the conveying platform 1, the conveying chamber 4 having a through structure, a plurality of rotating rods 21 being installed inside the conveying chamber 4, the rotating rods 21 being evenly distributed, the front and rear ends of the rotating rods 21 being rotatably connected to the inner wall of the conveying chamber 4, belt rollers 5 being fixedly installed on the outside of the rotating rods 21, a conveyor belt 6 being sleeved on the outside of the belt rollers 5, a first motor 3 being fixedly installed at the front and rear ends of both sides of the outside of the conveying platform 1, the output shaft of the first motor 3 extending into the inside of the conveying chamber 4 and fixedly connected to the rotating rods 21, support rods 2 being fixedly installed at the four corners of the lower end of the conveying platform 1, and anti-leakage strips 7 being installed at the front and rear ends of the outside of the conveyor belt 6, the anti-leakage strips 7 being an integral structure with the conveyor belt 6.
[0024] Please see Figure 1 , Figure 2 and Figure 4 A storage tank 13 is installed above one side of the conveyor platform 1. The upper end of the storage tank 13 is open. A lid 14 is installed at the upper end of the storage tank 13. The lid 14 is connected to the storage tank 13 by a snap-fit. A stirring rack 17 is installed at the lower end of the lid 14. The stirring rack 17 is rotatably connected to the lid 14. A heating wire 18 is fixedly installed inside the side wall of the storage tank 13. The heating wire 18 is distributed in a spiral structure. A second motor 15 is fixedly installed at the center of the upper end of the lid 14. The output shaft of the second motor 15 extends to the lower part of the lid 14 and is fixedly connected to the stirring rack 17. An exhaust pipe 16 is fixedly installed at the upper end of the lid 14 on the side of the second motor 15. The exhaust pipe 16 is connected to the storage tank 13 to facilitate the evaporation of moisture inside the raw material through the heating wire 18.
[0025] Please see Figure 1 and Figure 3 A weighing component 9 is fixedly installed at the lower end of the fixed end of the damper 10, and an mounting plate 8 is fixedly installed at the lower end of the weighing component 9. The lower end of the mounting plate 8 is fixedly connected to the conveyor table 1, so as to facilitate the metering and conveying of raw materials through the weighing component 9.
[0026] Please see Figure 1 and Figure 3 Connecting seats 12 are fixedly installed at the front and rear ends of the storage tank 13. A damper 10 is fixedly installed at the lower end of the connecting seat 12. A support spring 11 is fixedly installed at both the fixed end and the telescopic end of the damper 10, so that the vibration generated by the second motor 15 can be absorbed through the damper 10 and the support spring 11.
[0027] Working principle: In use, first, the heating wire 18 is energized. The heating wire 18 itself has a certain resistance; when current flows through it, heat is generated. This heat is transferred through the side wall of the storage tank 13 to the inside of the tank, raising the temperature of the raw materials until they reach a suitable temperature. Simultaneously, the second motor 15 is activated, causing its output shaft to drive the stirring frame 17 to rotate. The rotation of the stirring frame 17 agitates the raw materials inside the storage tank 13. The rotation of the rotor inside the second motor 15 generates vibration, which is transmitted through the storage tank 13 to the connecting seat 12. This will cause compression on the damper 10 and the support spring 11. After compression, the damper 10 and the support spring 11 will deform. The vibration on the connecting seat 12 will be absorbed by the deformation of the damper 10 and the support spring 11. When it is necessary to discharge the material, the drying of the raw material has been completed and the second motor 15 and the heating wire 18 have been turned off. At this time, the operator records the overall weight data of the raw material and the storage tank 13, opens the valve 19, and allows the raw material to be discharged from the storage tank 13 through the discharge pipe 20. At the same time, the weight data gradually decreases, and the operator monitors the change of the weight data in real time until the appropriate discharge amount is reached. At this time, the valve 19 is closed and the operator records the weight data again.
