Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, and in particular to an automatic feeding device for the production of biodegradable plastics. Background Technology

[0002] Biodegradable plastics are plastics that have a certain amount of additives added during the production process, such as starch, modified starch or other cellulose, photosensitizers, biodegradable agents, etc., which reduce their stability and make them easier to degrade in the natural environment without causing pollution.

[0003] An automatic feeding device for biodegradable plastic production disclosed in Chinese patent CN221758927U includes a base plate; a support rod is fixedly connected to the top of the base plate, and two sets of the support rod are arranged symmetrically front and back; a feeding box is fixedly connected to the opposite side of the support rod, and a feeding platform is fixedly connected to the bottom of the feeding box; a fixing plate is fixedly connected to the top of the feeding box, and two sets of the fixing plate are arranged symmetrically front and back.

[0004] In the aforementioned existing device, a spring pushes a sliding rod to drive an extrusion block to fix the raw material bag. A distribution plate can more disperse the raw material onto the feeding platform surface, and the feeding rod then transports the raw material out. However, the raw material particles used in biodegradable plastic production vary in size, requiring screening before feeding. The aforementioned existing device lacks a screening structure for the raw material, resulting in low processing efficiency.

[0005] To address the aforementioned problems, this utility model proposes an automatic feeding device for the production of biodegradable plastics. Utility Model Content

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This automatic feeding device for biodegradable plastic production uses a scraper to automatically scrape the surface of the filter screen, causing the filter screen to shake automatically and disperse the raw materials on the filter screen surface.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: an automatic feeding device for biodegradable plastic production, including a base plate 1, a support plate 2 fixedly installed on the upper end surface of the base plate 1, a feeding box 3 fixedly installed on the side wall of the support plate 2, and a fixing ring 6 fixedly installed inside the feeding box 3.

[0023] A filter screen 8 is provided on the bottom side of the fixing ring 6 to limit its vertical movement. Multiple second elastic elements 7 are evenly fixedly installed on the lower end face of the fixing ring 6, and the other end of the second elastic elements 7 is fixedly connected to the filter screen 8.

[0024] A scraper 14 is rotatably mounted on the upper end face of the filter screen 8, and a drive assembly for driving the filter screen 8 to move up and down is rotatably arranged inside the feed box 3.

[0025] The drive assembly includes a rotating ring 15, which is rotatably mounted on the inner wall of the feeding box 3. Multiple rotating blocks 16 are evenly fixedly mounted on the upper surface of the rotating ring 15. Matching blocks 9 are fixedly connected to the bottom side of the filter screen 8 at positions corresponding to the rotating blocks 16, and the rotating blocks 16 slide against the matching blocks 9. The filter screen 8 moves up and down due to the inclined surface engagement between the rotating blocks 16 and the matching blocks 9, as well as the engagement with the second elastic element 7.

[0026] A motor 11 is fixedly installed on the bottom surface of the material distribution plate 10. A telescopic rod 13 is fixedly connected to the upper output shaft of the motor 11. The telescopic rod 13 is fixedly connected to the rotating ring 15 and is rotatably connected to the material distribution plate 10. The telescopic end of the telescopic rod 13 rotates through the filter screen 8, and the top end of the telescopic rod 13 is fixedly connected to the scraper 14.

[0027] The bottom of the feeding box 3 is tapered, and a feeding rod 12 is rotatably mounted inside the bottom of the feeding box 3. The lower output shaft of the motor 11 is fixedly connected to the feeding rod 12. The feeding rod 12 has a specific structure consisting of a bearing and a spiral blade, which is a commonly used spiral feeding structure.

[0028] Inside the feeding box 3, below the filter screen 8, a material distribution plate 10 is fixedly installed. Due to the convex plate on the surface of the material distribution plate 10, the raw materials can be more dispersed and fall into the bottom of the feeding box 3.

[0029] Both sides of the upper end face of the feeding box 3 are fixedly installed with first elastic elements 4, and clamping plates 5 are fixedly installed on the opposite ends of the two first elastic elements 4. The first elastic elements 4 and the second elastic elements 7 have the same structure, specifically a metal telescopic rod and a spring, with the spring sleeved on the outside of the metal telescopic rod.

[0030] Working principle:

[0031] When in use, place the bag containing the raw material between the two clamps 5. The clamps 5 will automatically clamp and fix the bag. The raw material falls onto the filter screen 8 inside the feed box 3 and is filtered by the filter screen 8.

[0032] The start motor 11 drives the telescopic rod 13 to rotate, which in turn drives the scraper 14 to scrape the raw material on the surface of the filter screen 8. The rotating rod 13 drives the rotating ring 15 and the rotating block 16 on it to rotate. Through the cooperation of the rotating block 16 with the inclined surface of the mating block 9 and the second elastic element 7, the filter screen 8 is driven to shake up and down. The telescopic rod 13 drives the scraper 14 to rotate and disperse the raw material on the surface of the filter screen 8. Then, the raw material falls onto the distribution plate 10 after passing through the filter screen 8. Due to the convex plate on the surface of the distribution plate 10, the raw material can be more dispersed and fall into the bottom of the feeding box 3. Through the rotation of the feeding rod 12, the raw material can be gradually conveyed downward. As the raw material in the bag decreases, the two clamps 5 gradually move closer to each other until the raw material in the bag is completely discharged. The two clamps 5 still hold the bag.

[0033] 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.
