Modified recycled plastic particles not only help environmental protection, reduce landfill and marine pollution, but also save resources and reduce production costs.

[0003] In the production process of modified recycled plastic particles, a feeding device is needed to transport plastic particles to product packaging for subsequent processing. Currently, most existing feeding devices use conical hoppers for feeding. Although this allows plastic particles to fall accurately into product packaging, the amount of plastic particles in each product packaging needs to be maintained at approximately the same quantity. The existing feeding device is not convenient for controlling the size of the discharge opening and the discharge amount of plastic particles, which can lead to uneven quantities of plastic particles during feeding, requiring workers to make secondary adjustments, which is inconvenient. Therefore, a modified recycled plastic particle quantitative feeding device is proposed to solve the above problems. SUMMARY

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1 to 4 The modified recycled plastic granule quantitative feeding device in this embodiment includes a feeding tank 1 and a base 2. The bottom of the feeding tank 1 is fixedly connected to a column 3 and a discharge pipe 4. A quantitative control component is provided on the outside of the feeding tank 1.

[0020] A hydraulic cylinder 5 and a sleeve 10 are fixedly connected to the top of the quantitative control component base 2. The output shaft of the hydraulic cylinder 5 is fixedly connected to a lifting platform 6. A feeding box 7 is fixedly connected to the top of the lifting platform 6. A conical protrusion 8 is fixedly connected to the inner bottom wall of the feeding box 7. Feeding pipes 9 are fixedly connected to the left and right sides of the feeding box 7. A piston block 11 is slidably connected inside the sleeve 10. A damping spring 12 is fixedly connected inside the sleeve 10. A piston rod 13 is fixedly connected to the top of the piston block 11. In use, plastic granules are discharged into the feeding box 7 through the discharge pipe 4, and then discharged outward through the feeding pipes 9 on the left and right sides of the feeding box 7 to be transported to the product packaging.

[0021] During material discharge, the hydraulic cylinder 5 drives the lifting platform 6 to rise and fall. When the lifting platform 6 rises, the conical protrusion 8 on the bottom wall of the feeding box 7 will continuously approach the discharge pipe 4 and eventually insert into the discharge pipe 4 to reduce the size of the discharge port of the discharge pipe 4 or directly close the discharge port. Conversely, when the lifting platform 6 falls, the conical protrusion 8 on the bottom wall of the feeding box 7 will continuously move away from the discharge pipe 4 and eventually detach from the discharge pipe 4 to expand the size of the discharge port of the discharge pipe 4 or directly open the discharge port completely, thereby achieving quantitative control of plastic granules.

[0022] During the lifting process of the lifting platform 6, the staff can control the lifting height and lifting interval of the lifting platform 6 through the hydraulic cylinder 5, so as to indirectly adjust the size of the discharge port and the discharge time of the discharge pipe 4, thereby controlling the discharge amount of plastic granules, ensuring that the amount of plastic granules in each product package is kept within a general range, and thus avoiding uneven quantity.

[0023] Finally, when the hydraulic cylinder 5 lowers the lifting platform 6 to a certain height, the sleeve 10 can maintain the horizontal height of the lifting platform 6 by using the cooperation of the piston block 11, the damping spring 12 and the piston rod 13, so as to avoid the situation where the material box 7 is far away from the discharge pipe 4, so as to ensure that the plastic particles can be accurately discharged into the material box 7. At the same time, it can also maintain the current horizontal height of the lifting platform 6 in real time without using the hydraulic cylinder 5, thereby improving the service life of the output shaft of the hydraulic cylinder 5.

[0024] It should be noted that there are four columns 3, the lifting platform 6 is slidably connected to the columns 3, the bottom of the piston block 11 is fixedly connected to the top of the damping spring 12, and there are two sleeves 10, which are symmetrically distributed on the left and right sides of the hydraulic cylinder 5.

[0025] It should be understood that the bottom of the column 3 is fixedly connected to the top of the base 2, and the base 2 is a square solid structure.

[0026] The top of the feeding tank 1 is fixedly connected to the feeding pipe 14 and the cooling fan 15. The top and bottom of the cooling fan 15 are fixedly connected to the filter screen. By setting the cooling fan 15, air can be blown into the inside of the feeding tank 1, thereby achieving the effect of cooling down the plastic particles.

[0027] Meanwhile, a servo motor 16 is fixedly connected to the right side of the feeding tank 1. The output shaft of the servo motor 16 is fixedly connected to a rotating shaft 17. An agitator 18 for breaking up plastic particles is fixedly connected to the outer surface of the rotating shaft 17. Through the cooperation of the servo motor 16, the rotating shaft 17 and the agitator 18, the plastic particles conveyed to the inside of the feeding tank 1 can be broken up to avoid sticking together.

[0028] In addition, an observation window 19 is fixedly connected to the outer surface of the feeding tank 1. The observation window 19 is made of tempered glass.

[0029] The working principle of the above embodiments is as follows:

[0030] In use, plastic granules are first discharged into the feeding tank 1 through the feed pipe 14. At this time, the cooling fan 15 and servo motor 16 are started to cool and disperse the plastic granules. Then, the plastic granules are discharged into the feeding box 7 through the discharge pipe 4, and then discharged outward through the discharge pipes 9 on the left and right sides of the feeding box 7 to be transported to the product packaging. During discharge, the hydraulic cylinder 5 can drive the lifting platform 6 to rise and fall. When the lifting platform 6 rises, the conical protrusion 8 on the bottom wall of the feeding box 7 will continuously approach the discharge pipe 4 and eventually insert into the discharge pipe 4 to reduce the size of the discharge opening of the discharge pipe 4, or directly... The discharge port is closed. In addition, when the lifting platform 6 is lowered, the conical protrusion 8 on the bottom wall of the feeding box 7 will continuously move away from the discharge pipe 4 and eventually detach from the discharge pipe 4 to expand the size of the discharge port of the discharge pipe 4, or directly open the discharge port completely, thereby realizing quantitative control of plastic granules. During the lifting process of the lifting platform 6, the operator can control the lifting height and lifting interval time of the lifting platform 6 through the hydraulic cylinder 5 to indirectly adjust the size of the discharge port of the discharge pipe 4 and the discharge time, so as to control the discharge amount of plastic granules, ensure that the amount of plastic granules in each product package is maintained within a general range, and thus avoid uneven quantity.
