Abstract
Description
Technical Field
[0001] The present application relates to the technical field of plastic manufacturing, and in particular to a device for accurately proportioning and feeding PVC particles. Background Art
[0002] The production and processing of plastic particles such as PVC granules involves the process of coloring the PVC granules with liquid colorants. Usually, the PVC granules and the liquid colorants need to be mixed together in a specified ratio, and a corresponding proportioning and feeding device needs to be used to allow the PVC granules and the liquid colorants to be mixed in proportion for subsequent processing.
[0003] For example, the publication number is CN220425259U, which is an automatic feeding device with precise proportion. It can also achieve precise proportion feeding by mixing a solid material and a liquid material in proportion. However, the automatic feeding device with precise proportion still has the following disadvantages in actual use:
[0004] The above-mentioned automatic feeding device with precise proportioning drives the feeding control disk to rotate counterclockwise through the reduction motor, so that the lower ends of the quantitative bean cup and the quantitative water cup are aligned with the bean dispensing port and the water dispensing port, thereby realizing quantitative feeding. However, when the lower ends of the quantitative bean cup and the quantitative water cup are not aligned with the bean dispensing port and the water dispensing port, the materials in the quantitative bean cup and the quantitative water cup have already begun to leak out, and the bean dispensing port and the water dispensing port are of different sizes, making it difficult to count the materials that leak out when they are not aligned, which can easily affect the feeding ratio of the materials and make the feeding ratio effect poor. Therefore, there is still room for improvement. Utility Model Content

DETAILED DESCRIPTION
[0027] The following is combined with Figure 1-2 This application is described in further detail.
[0028] The present application discloses a device for accurately proportioning and feeding PVC particles. Figure 1 and Figure 2A PVC rubber pellet precise proportioning feeding device comprises a frame 1, a turntable 2 is rotatably connected to the frame 1, the turntable 2 is arranged horizontally, a driving motor 3 is fixed to the frame 1, the output shaft of the driving motor 3 is arranged vertically downward, a gear 4 is fixed to the output shaft of the driving motor 3, a toothed disc 5 is fixed to the bottom of the turntable 2, the outer diameter of the toothed disc 5 is the same as the outer diameter of the turntable 2, and the toothed disc 5 is meshed with the gear 4. The output shaft of the driving motor 3 rotates to drive the gear 4 to rotate, and the rotation of the gear 4 drives the toothed disc 5 to rotate. A feed hopper 6 is fixed to the turntable 2, and two feed hoppers 6 are arranged side by side, and the feed hoppers 6 are arranged in an inverted cone shape. When the toothed disc 5 rotates, it will drive the feed hopper 6 to rotate. A feed cup 7 is fixed to the bottom of the turntable 2, and two feed cups 7 are arranged corresponding to the number of feed hoppers 6, and the feed cup 7 is located below the feed hopper 6. A feed valve 8 is provided on the hopper, and the feed cup 7 is connected or separated from the feed hopper 6 by the feed valve 8. A storage barrel 9 is fixed on the frame 1, and a feed port 10 is provided on the storage barrel 9. There are two feed ports 10. The bottom of the feed cup 7 abuts against the bottom surface of the storage barrel 9. The feed cup 7 can be connected with the feed port 10 by rotating the turntable 2.
[0029] Furthermore, a feed pipe 11 is provided at the feed port 10, and the feed pipe 11 is provided corresponding to the number and position of the feed port 10, and the feed pipe 11 is provided in a bent manner, and the pipe mouth of the feed pipe 11 is provided in an inclined manner toward the middle of the storage barrel 9. The PVC particles and colorant are poured into the two feed hoppers 6, and the feed valve 8 is closed at this time, and the drive motor 3 drives the gear 4 to rotate, thereby driving the gear plate 5 to rotate, and the gear plate 5 rotates to drive the turntable 2 to rotate, thereby driving the feed hopper 6 and the feed cup 7 to rotate, so that the feed cup 7 is connected with the feed port 10 on the storage barrel 9, and the feed valve 8 is opened at this time, and the PVC particles and colorant enter the feed cup 7 from the feed hopper 6 and then enter the storage barrel 9 for mixing. The pipe mouth of the feed pipe 11 is provided in an inclined manner toward the middle of the storage barrel 9, so that the PVC particles and colorant can collide with each other when they come out of the feed pipe 11, achieving a better mixing effect. The feed valve 8 is opened only when the feed cup 7 is connected to the feed port 10 on the storage barrel 9. When the feed cup 7 is rotating, the colorant is not easy to leak out when the feed cup 7 is not aligned with the feed port 10, which is not easy to affect the material addition ratio, making the addition ratio effect better, thereby realizing the precise proportioning and feeding operation of PVC particles, reducing material waste and saving resources.
[0030] In addition, scale marks 12 are provided on the inner side walls of the two feed hoppers 6. In the process of the PVC granules and colorant entering the feed cup 7 from the feed hopper 6 and then entering the storage barrel 9 for mixing, the operator can judge the feeding amount of the PVC granules and colorant by observing the position of the remaining PVC granules and colorant in the feed hopper 6 reaching the scale mark 12. When the feeding amount reaches the requirement, the feeding valve 8 on the feed hopper 6 can be controlled to close, thereby improving the accuracy of the proportioning and feeding device.

In the process of the PVC particles and the colorant entering the storage barrel 9 from the feed pipe 11, the stirring piece 13 rotates continuously, so that the PVC particles and the colorant are initially mixed together, which is convenient for subsequent better mixing and coloring. And the mouth of the feed pipe 11 is inclined toward the middle of the storage barrel 9. The feed pipe 11 guides the PVC particles and the colorant to the stirring piece 13, so that the PVC particles and the colorant are better stirred and mixed. A discharge pipe 14 is fixed at the bottom of the storage barrel 9. The discharge pipe 14 is bent, and the mouth of the discharge pipe 14 is arranged toward the side of the outer wall of the storage barrel 9. A discharge valve 15 is fixed on the discharge pipe 14. After the PVC particles and the colorant are mixed in a good proportion, the discharge valve 15 is opened, and the mixed PVC particles and the colorant are discharged through the discharge pipe 14, and then further mixed and colored.
[0032] The implementation principle of a PVC pellet precise proportioning and feeding device in the embodiment of the present application is as follows:
[0033] Pour the PVC granules and colorant into the two feed hoppers 6. At this time, the feed valve 8 is closed, and the drive motor 3 drives the gear 4 to rotate, thereby driving the gear plate 5 to rotate. The rotation of the gear plate 5 drives the turntable 2 to rotate, thereby driving the feed hopper 6 and the feed cup 7 to rotate, so that the feed cup 7 is connected with the feed port 10 on the storage barrel 9. At this time, the feed valve 8 is opened, and the PVC granules and colorant enter the feed cup 7 from the feed hopper 6 and then into the storage barrel 9 for mixing.
[0034] When the PVC particles and colorant enter the storage barrel 9 from the feed pipe 11, the stirring member 13 rotates continuously, so that the PVC particles and colorant are initially mixed together, which is convenient for subsequent better mixing and coloring. The operator can judge the feeding amount of the PVC particles and colorant by observing the position of the remaining PVC particles and colorant in the feed hopper 6 to the scale mark 12. When the feeding amount reaches the requirement, the feed valve 8 on the feed hopper 6 can be controlled to close. After the PVC particles and colorant are mixed and matched, the discharge valve 15 is opened, and the mixed PVC particles and colorant are discharged through the discharge pipe 14, and then further mixed and colored.
