[0002] In the production of Chinese medicinal herbs, the purity of the products is subject to strict standards, and purification equipment such as air classifiers, color sorters, and sieves are commonly used. To ensure product purity, a conveyor belt is connected to the outlet of the purification equipment for manual sorting. In the current production process, the medicinal materials are discharged vertically from the outlet onto the conveyor belt, resulting in some localized accumulation. Workers then need to manually spread and break up the materials during sorting. Firstly, this distracts workers from selecting impurities, affecting the quality of the medicinal products; secondly, it reduces the efficiency of the preparation process. Utility Model Content

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0024] See Figures 1 to 4 As shown, this utility model embodiment provides a material feeding device for a conveyor belt device. The material feeding device is disposed on the conveyor belt 3 and is located below the discharge port of the equipment.

[0025] Specifically, it includes support 1 and fabric feeder 2;

[0026] The support 1 is fixed on the conveyor belt 3, the material distributor 2 is slidably connected to the support 1, the surface of the material distributor 2 is provided with a material dispersion surface 21, the material dispersion surface 21 is an arc surface, and the discharge direction of the material distributor 2 has a predetermined angle with the conveying direction of the conveyor belt 3.

[0027] This utility model includes a support 1 and a material distributor 2. The support 1 is fixed to the conveyor belt 3, and the material distributor 2 is slidably connected to the support 1. Firstly, the surface of the material distributor 2 is provided with a material dispersion surface 21. The material dispersion surface 21 is an arc surface, which can evenly disperse the medicinal materials on its surface, allowing them to flow along its surface to the discharge end of the material distributor 2. Secondly, the discharge direction of the material distributor 2 has a predetermined angle with the conveyor belt 3's conveying direction, which can reduce the impact of materials falling onto the conveyor belt 3 and prevent material accumulation on the conveyor belt 3. The structure is simple, can evenly disperse materials on the conveyor belt 3, and is used in the cleaning process of traditional Chinese medicine materials, effectively improving the efficiency and accuracy of selecting impurities in the medicinal materials.

[0028] To increase the width of the medicinal materials on the conveyor belt 3, preferably, the width of the material dispersion surface 21 gradually decreases along the conveying direction of the conveyor belt 3; the discharge end of the material dispersion surface 21 is provided with a leading edge portion 22, the width of the leading edge portion 22 gradually decreases along the conveying direction of the conveyor belt 3; the material dispersion surface 21 and the leading edge portion 22 are integrally formed.

[0029] As the material falls onto the material distribution surface 21, the width of both the material distribution surface 21 and the leading edge 22 gradually decreases along the conveying direction of the conveyor belt 3. When the material falls onto the material distribution surface 21 at a position far from the output end of the distributor 2, its ejection point is closer to the output end of the distributor 2 and located near the edge of the conveyor belt 3. When the material falls onto the material distribution surface 21 at a position close to the output end of the distributor, its ejection point is near the middle of the conveyor belt and further away from the distributor. This ensures that the medicinal material can be evenly spread over a larger area on the conveyor belt 3, making it easier for manual removal of impurities from the medicinal material.

[0030] During the descent of the medicinal materials, there is a possibility that they will fall to the end furthest from the output end of the distributor 2, causing material to accumulate on the conveyor belt 3. Preferably, a baffle 23 is provided on the back of the distributor 2. The baffle 23 prevents material from entering the bottom structure and causing material residue.

[0031] The angle between the discharge direction of the material distributor 2 and the conveying direction of the conveyor belt 3 affects the distribution of Chinese medicinal materials on the conveyor belt 3. Preferably, the angle between the discharge direction of the material distributor 2 and the conveying direction of the conveyor belt 3 is α, where α is 20-35°. When α is greater than 35°, the material falls vertically, resulting in a narrow distribution range and easy accumulation at the near end of the conveyor belt 3. When α is less than 20°, the horizontal velocity accounts for a high proportion, and the material is thrown to the far end, leading to accumulation at the far end and sparse distribution at the near end.

[0032] The distance between the material distributor 2 and the outlet of the equipment, as well as the distance between the material distributor 2 and the conveyor belt 3, affects the kinetic energy and impact effect of the material, thus affecting the material distribution effect of the material distributor 2. Preferably, the distance between the material distributor 2 and the outlet of the equipment is H1, and the distance between the material distributor 2 and the conveyor belt 3 is H2, with the ratio of H1 to H2 being 1:1 to 1:2. When the ratio is greater than 1:1, the value of H1 is too large, and the material impacts the material dispersion surface 21 at high speed from the outlet, resulting in rebound, splashing, or local accumulation. When the ratio is less than 1:1, the residence time of the material on the material dispersion surface 21 is insufficient, and it falls without fully dispersing.

[0033] Preferably, it also includes a fixing screw 25, and a crossbeam 24 is provided on the fabric feeder 2. The crossbeam 24 is sleeved on the fixing screw 25 and threadedly connected to the surface of the fixing screw 25. The fixing screw 25 is threadedly connected to the two ends of the crossbeam 24 with first fastening nuts 26.

[0034] The bracket 1 is provided with sliding rails 11 on both sides. Both ends of the fixing screw 25 extend into the sliding rails 11 and pass through the sliding rails 11. One end of the fixing screw 25 is provided with a second fastening nut 27 on both sides of the sliding rail 11, and is fastened to the bracket 1 by the second fastening nut 27. A handle 28 is provided on the end of the fixing screw 25 near the second fastening nut 27.

[0035] Preferably, a buffer layer 211 is provided at the bottom of the material dispersion surface 21, and the buffer layer 211 is made of silicone or natural rubber. This can effectively reduce the impact noise between the material and the material dispersion surface 21.

[0036] This embodiment also provides a conveyor belt device, including the fabric feeding device described above.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
