AI Technical Summary
The efficiency of cutting Polygonum multiflorum vine into segments in the existing technology is low, mainly because its slightly twisted shape and varying lengths and thicknesses make manual segmentation difficult.
Design a cutting device that uses an airbag to fix the Polygonum multiflorum vine and drives the rotating shaft to move the vine by a main motor. At the same time, an electric rod pushes the knife holder and the knife to cut the vine into sections. The cut vine is then collected by a collection box.
This method improves the efficiency and convenience of cutting Polygonum multiflorum vine into segments, achieving automated segmentation and greatly enhancing processing efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4This utility model provides a technical solution: a cutting device for Polygonum multiflorum vine, comprising: a workbench 1, a cutting groove 2 on the top of the workbench 1, a placement box 3 fixedly connected to the top of the workbench 1, the placement box 3 being U-shaped, the cutting groove 2 being located on the right side of the placement box 3 for placing Polygonum multiflorum vine strips side by side, and a feeding assembly 4 above the placement box 3, the number of feeding assemblies 4 being two, evenly distributed left and right, the feeding assembly 4 including a fixed plate 401, a main motor 402, a rotating shaft 403, an airbag 404, an inflation nozzle 405, and a valve 406, the bottom of the fixed plate 401 being fixedly connected to the workbench 1, the main motor 402 being fixedly connected to the front side wall of the fixed plate 401, and the rotating shaft 403 being rotatably connected to the rear side wall of the fixed plate 401, the output end of the main motor 402 being connected to the rotating shaft 403. An airbag 404 is fixedly connected to the circumference of the rotating shaft 403. The airbag 404 is made of wear-resistant soft rubber and has anti-slip texture on its outer circumference. An inflation nozzle 405 is fixedly connected to the front side wall of the airbag 404, and a valve 406 is fixedly connected to the inflation nozzle 405. The airbag 404 can be inflated by the inflation nozzle 405, thereby stabilizing the Polygonum multiflorum vine inside the placement box 3. When the main motor 402 is started, the rotating shaft 403 and the airbag 404 can be rotated, thereby moving the Polygonum multiflorum vine to the left. The airbag 404 in the right feeding assembly 4 can stabilize the right end of the excessively long Polygonum multiflorum vine. The airbag 404 is located above the placement box 3. The rear side wall of the rotating shaft 403 is rotatably connected to the back plate 5, and the fixing plate 401 is located in front of the placement box 3.
[0024] A back plate 5 is fixedly connected to the top of the workbench 1, a top plate 6 is fixedly connected to the top of the back plate 5, and a baffle 7 and an electric rod 8 are fixedly connected to the bottom of the top plate 6. There are two electric rods 8, which are symmetrically arranged front and back. A knife holder 9 is fixedly connected to the bottom of the electric rod 8, and a knife 10 is fixedly connected to the bottom of the knife holder 9. The knife 10 is located above the cutting groove 2, and the baffle 7 is located on the left side of the cutting groove 2. When the Polygonum multiflorum vine moves to the left and is blocked by the baffle 7, the electric rod 8 is activated, causing the knife holder 9 and the knife 10 to move down and cut the Polygonum multiflorum vine into segments. The cut Polygonum multiflorum vine segments fall from the cutting groove 2 into the collection box 11.
[0025] A collection box 11 is fixedly connected to the bottom of the workbench 1. A sealing plate 12 is provided at the bottom of the collection box 11. The collection box 11 and the sealing plate 12 are connected by a hinge and fixed by a lock. When the sealing plate 12 is opened, the sections of Polygonum multiflorum vine inside can be discharged.

[0027] Working principle: The Polygonum multiflorum vine strips are placed inside the placement box 3. Then, the air bladder 404 is inflated by the air inlet 405, which inflates the air bladder 404 and stabilizes the Polygonum multiflorum vine strips inside the placement box 3. When the main motor 402 is started, the rotating shaft 403 and the air bladder 404 are rotated, which allows the Polygonum multiflorum vine strips to move to the left. When the Polygonum multiflorum vine strips move to the left and are blocked by the baffle 7, the electric rod 8 is started, which moves the knife holder 9 and the knife 10 down to cut the Polygonum multiflorum vine strips into segments. The air bladder 404 in the right feeding assembly 4 can stabilize the right end of the excessively long Polygonum multiflorum vine strips, making it easy to cut them stably. The cut Polygonum multiflorum vine strips fall from the cutting groove 2 into the collection box 11. After a period of time, the sealing plate 12 can be opened to discharge the Polygonum multiflorum vine strips into segments.
[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
