These feeding devices generally have the following problems: 1. Unstable filling accuracy control, resulting in low product qualification rates; 2. Material jamming can occur with materials of uneven size, affecting equipment speed and reducing production capacity; 3. The feeding process can damage the pills, easily leading to broken pills and material waste. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a pellet material feeding device with stable filling accuracy, high product qualification rate, and the ability to avoid material jamming and pellet breakage, thereby improving production efficiency.
[0004] The technical solution of this utility model is as follows:
[0005] A pill material feeding device includes a base plate and a material bin supported on the base plate. The special feature is that a feeding plate is slidably installed on the base plate via symmetrically arranged slide rails. The feeding plate is attached to the lower end of the material bin. Multiple sets of discharge holes are evenly distributed on the feeding plate. Each set of discharge holes consists of multiple arrow-shaped waist-shaped elongated holes arranged at equal intervals for dropping the pill material to be fed.
[0006] A material support plate is fixed on the bottom plate below the hopper. The material support plate slides in contact with the bottom surface of the feeding plate to block the discharge hole.
[0007] A discharge port is provided at the lower end of a long plate on one side of the hopper. A brush is provided inside the discharge port, and a baffle is provided outside the discharge port. The lower ends of the brush and the baffle are close to the upper surface of the feeding plate, which is used to scrape excess material away from the discharge hole when the feeding plate feeds.
[0008] A drive device is provided on one side of the material outlet of the silo. The output end of the drive device is connected to the feeding plate, which is used to drive the feeding plate to slide back and forth to achieve quantitative feeding.
[0009] As a further preferred embodiment, the arrow of the elongated hole in each set of feeding holes points to the side of the drive device.
[0010] As a further preferred option, a hopper support plate is provided on the bottom plate on the side of the material outlet of the hopper. Multiple hoppers are evenly distributed on the hopper support plate and correspond one-to-one with multiple sets of discharge holes. The upper part of the hopper is square pyramidal and the lower part is tubular. The upper end of the hopper is close to one edge of the material tray and is used to discharge the pill material sent out by the feeding plate.
[0011] As a further preferred option, a feeding sleeve is provided at the top of the hopper, and an upper cover plate is fixed at the top of the feeding sleeve. Multiple feeding ports are evenly distributed on the upper cover plate to facilitate the addition of materials.
[0012] As a further preferred embodiment, the hopper is a rectangular frame formed by connecting two long plates and two short plates, with the outer sides of the short plates at both ends of the hopper supported on the base plate by two L-shaped supports.
[0013] As a further preferred embodiment, a baffle plate is fixed to the outside of the material outlet of the hopper by fixing screws, and the baffle plate is a silicone plate and fixed inside the baffle plate.
[0014] As a further preferred embodiment, the driving device includes a servo motor and a reducer. A drive shaft is connected to the output end of the reducer, and a turntable is fixed to the other end of the drive shaft. A groove is provided radially on the turntable, and a short shaft with adjustable position is installed in the groove. A connecting rod with adjustable length is hinged to the short shaft, and the other end of the connecting rod is hinged to the feeding plate to facilitate adjustment of the sliding stroke of the feeding plate. When the feeding plate slides to the front end, each set of feeding holes moves to the top of the corresponding feeding hopper, thereby realizing feeding.
[0015] The beneficial effects of this utility model are:
[0016] 1. Each set of feeding holes consists of multiple arrow-shaped and waist-shaped elongated holes arranged at equal intervals, which greatly improves the feeding rate and makes the filling accuracy more stable. The filling accuracy of each set can reach ±5%, and the product qualification rate can reach 99.8%. Moreover, it has good versatility and is suitable for pill materials with large roundness errors.
[0017] 2. Because a brush is installed inside the discharge port and a baffle is installed outside the discharge port, excess material can be scraped away from the discharge hole by the brush and the baffle. This not only better protects the pellet material from breaking and improves the integrity of the material, but also prevents material jamming during the production process, greatly improving production efficiency.

[0027] like Figures 1-6 As shown, the present invention relates to a pill material feeding device, which includes a frame 1, a base plate 3 fixed on the frame 1, and a material bin 7 supported above the base plate 3. The material bin 7 is a rectangular frame formed by connecting two long plates and two short plates with screws. The outer sides of the short plates at both ends of the material bin 7 are supported on the base plate 3 by two L-shaped supports 5 respectively.
[0028] A feeding sleeve 8 is fitted onto the upper opening of the hopper 7 and fixed with screws. An upper cover plate 9 is fixed to the upper end of the feeding sleeve 8 with clamping screws. Multiple feeding ports 901 are evenly distributed on the upper cover plate 9 to facilitate the addition of materials.
[0029] A feeding plate 2 is slidably mounted on the base plate 3 below the hopper 7 via two symmetrically arranged slide rails 4 and a slider. The feeding plate 2 is attached to the lower port of the hopper 7 and can block the lower port of the hopper 7 when it slides to the front and rear stop points. Multiple sets of discharge holes 201 are evenly distributed on the feeding plate 2 along the length of the hopper 7. This embodiment takes six sets of discharge holes 201 as an example. Figure 7 As shown, each set of feeding holes 201 consists of multiple arrow-shaped waist-shaped elongated holes arranged at equal intervals. In this embodiment, nine elongated holes are used as an example. The arrangement direction of the multiple elongated holes is perpendicular to the arrangement direction of the multiple sets of feeding holes 201, and is used to drop the pill material to be fed.
[0030] A rectangular material support plate 6 is fixed on the base plate 3 below the hopper 7 by multiple evenly distributed pads. The material support plate 6 is attached to the bottom surface of the feeding plate 2 and slides in cooperation with the feeding plate 2 to block the discharge hole.
[0031] A rectangular discharge port 701 is provided at the lower end of one long plate of the hopper 7. A brush 20 is fixed to the inside of the discharge port 701 on the long plate of this side by screws. A baffle plate 22 is provided on the outside of the discharge port 701 on the long plate of this side. The lower ends of the brush 20 and the baffle plate 22 are close to the upper surface of the feeding plate 2, and are used to scrape excess material away from the discharge port 201 when the feeding plate 2 feeds. A baffle cover 10 is fixed to the outside of the discharge port 701 of the hopper 7 by fixing screws. The baffle plate 22 is a silicone plate and is fixed inside the baffle cover 10 by screws. An oblong hole is provided on the baffle cover 10 corresponding to the fixing screw to facilitate adjustment of the height of the baffle plate 22.
[0032] A drive device is provided on the frame 1 on one side of the discharge port 701 of the hopper 7. The output end of the drive device is connected to the feeding plate 2 and is used to drive the feeding plate 2 to slide back and forth to achieve quantitative feeding. The arrow of the elongated hole of each set of discharge holes 201 points to the drive device.
[0033] A hopper support plate 21 is fixed on the bottom plate 3 on one side of the discharge port 701 of the hopper 7. Multiple discharge hoppers 19 are evenly welded on the hopper support plate 21 and correspond one-to-one with multiple sets of discharge holes 201. The upper part of the discharge hopper 19 is square pyramidal and the lower part is cylindrical. The upper end of the discharge hopper 19 is close to one side edge of the material support plate 6 and is used to discharge the pill material sent out by the feeding plate 2.
[0034] The drive device includes a servo motor 15 and a reducer 16 connected to each other. A drive shaft 18 is connected to the output end of the reducer 16. The drive shaft 18 is rotatably mounted on the frame 1 via a bushing 17 and bearings fixed on the frame 1.

The large end of the short shaft 14 is flat and is inserted into the groove with a clearance fit. The short shaft is fixed to the turntable 13 by a nut. An adjustable connecting rod 12 is hinged to the short shaft 14, and the other end of the connecting rod 12 is hinged to a pin 11 fixed on the feeding plate 2. This allows for adjustment of the sliding stroke of the feeding plate 2, so that when the feeding plate 2 slides to the front end, each set of discharge holes 201 moves above the corresponding discharge hopper 19, thereby realizing the discharge.
[0035] During operation, the pill material to be fed is added into the hopper 7 through the feeding port; the servo motor 15 is started, and the drive shaft 18 is rotated through the reducer, thereby driving the turntable 13 to rotate at a low speed; when the turntable 13 rotates, the feeding plate 2 is pulled along the slide rail at a uniform speed through the connecting rod 12; when the multiple sets of discharge holes 201 on the feeding plate 2 slide into the hopper 7, the pill material in the hopper 7 falls into the multiple elongated holes of each set of discharge holes 201; as the feeding plate 2 slides forward, the excess material can be scraped away from the discharge holes 201 by the brush 20 and the baffle plate 22. When the multiple sets of discharge holes 201 on the feeding plate 2 are separated from the material support plate 6 below, the material will fall into the corresponding discharge hopper 19 and enter the next process of bagging through the discharge hopper 19.
