[0022] According to Figures 1-4 As shown, a feeding device of a PVC sheet processing raw material mixer includes a mixer body 1. A support frame 2 is provided on the side of the mixer body 1. A plurality of groups of feeding mechanisms are linearly and arrayedly arranged on the top of the support frame 2. The feeding mechanism includes a weighing ring 3. A batching bucket 5 is installed on the weighing ring 3. A feed pipe 6 is fixedly installed at the top of the batching bucket 5. A first baffle plug 7 is movably installed at the bottom end of the feed pipe 6. A discharge port 10 is provided at the center of the bottom end of the batching bucket 5. A second baffle plug 11 is movably installed at the discharge port 10. A connecting pipe 15 is movably installed below the discharge port 10. The connecting pipe 15 is movably installed on a conveying pipe 19. The conveying pipe 19 is communicated with the inside of the mixer body 1.

[0023] In this embodiment, the weighing ring 3 is fixedly installed on the top of the support frame 2. A fixed ring 4 is fixedly installed on the top of the weighing ring 3. The batching bucket 5 is fixedly installed on the fixed ring 4. The raw materials inside the batching bucket 5 are weighed by the weighing ring 3, so as to realize accurate weighing of the batching.

[0024] In this embodiment, the second baffle plug 11 is of a cylindrical structure. A first frustum 111 is provided at the bottom end of the second baffle plug 11. A first sealing surface 101 corresponding to the first frustum 111 is provided at the discharge port 10. The discharge port 10 is sealed by the abutment of the first frustum 111 and the first sealing surface 101, so as to prevent the batching in the batching bucket 5 from leaking outwards.

[0025] In this embodiment, a guide rod 12 is fixedly installed at the top of the second material blocking plug 11. The guide rod 12 is slidably installed on the cross plate 13. The cross plate 13 is fixedly connected and welded inside the batching barrel 5. A spring 14 is sleeved on the guide rod 12. The two ends of the spring 14 are respectively abutted against the cross plate 13 and the second material blocking plug 11. The axis of the guide rod 12 is on the same straight line as the axis of the discharge port 10. The second material blocking plug 11 is guided by the guide rod 12, and under the action of the spring 14, the second material blocking plug 11 blocks the discharge port 10.

[0026] In this embodiment, a second cylinder 8 is fixedly installed at the top of the batching barrel 5. A pressing plate 9 is fixedly installed on the power output shaft of the second cylinder 8. The first material blocking plug 7 is fixedly installed on the pressing plate 9. The first material blocking plug 7 is of a cylindrical structure. A second frustum 71 is provided at the top end of the first material blocking plug 7. A second sealing surface 61 corresponding to the second frustum 71 is provided at the bottom end of the feed pipe 6. The pressing plate 9 is driven by the second cylinder 8 to approach the feed pipe 6, so that the first material blocking plug 7 blocks the bottom end of the feed pipe 6, and the second frustum 71 abuts against the second sealing surface 61, thereby sealing the feed pipe 6 to prevent the batching from continuing to enter the batching barrel 5.

[0027] In this embodiment, the feeding mechanism further includes a first cylinder 16. The first cylinder 16 is fixedly installed on the mounting frame 17. The mounting frame 17 is fixedly installed at the bottom of the support frame 2. A connecting plate 18 is fixedly installed on the power output shaft of the first cylinder 16. The connecting plate 18 is fixedly connected and welded to the side wall of the connecting pipe 15. A plurality of groups of feeding grooves 151 are arranged in an array on the side wall of the top end of the connecting pipe 15. The feeding grooves 151 are located above the connecting plate 18. By driving the connecting plate 18 to rise or fall by the first cylinder 16, the connecting pipe 15 moves synchronously with the connecting plate 18. When the connecting pipe 15 rises, it will push the second material blocking plug 11 upward, and make the feeding grooves 151 at the top end of the connecting pipe 15 completely enter the inside of the batching barrel 5, so that the batching in the batching barrel 5 passes through the feeding grooves 151 and enters the connecting pipe 15.

[0028] In this embodiment, the conveying pipe 19 is fixedly installed on the top wall of the mixer body 1. One end of the conveying pipe 19 away from the mixer body 1 is inclined upward. A plurality of groups of blanking pipes 20 are linearly arranged in an array on the top side wall of the conveying pipe 19. The number of the blanking pipes 20 is the same as the number of the feeding mechanisms. The bottom end of the connecting pipe 15 is slidably connected to the blanking pipe 20. Driven by the first cylinder 16, the connecting pipe 15 moves along the pipe wall of the blanking pipe 20. The conveying pipe 19 is connected to the batching barrel 5 through the connecting pipe 15, so that the batching is gathered in the conveying pipe 19 and enters the mixer body 1 through the conveying pipe 19 for mixing.

[0029] When the utility model is in use, the feed pipe 6 of each batching barrel 5 is connected to different batching boxes through a hose. During feeding, the second cylinder 8 drives the first baffle plug 7 to move downward, so that the batching enters the batching barrel 5, and the batching barrel 5 is weighed by the weighing ring 3. After the material weight in the batching barrel 5 meets the set value, the second cylinder 8 resets, so that the first baffle plug 7 moves upward to block the feed pipe 6. Then, the first cylinder 16 drives the connecting pipe 15 to move upward to push the second baffle plug 11 upward, so that the batching enters the conveying pipe 19 through the connecting pipe 15 and enters the mixer body 1 through the conveying pipe 19 for mixing and stirring, thereby realizing the automatic proportioning and transportation of raw materials, reducing the consumption of labor costs, and further reducing the production costs of products.
