Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1 to Figure 6 As shown, the present invention relates to a pill material feeding device, comprising a frame 1, a bottom plate 3 is fixed on the frame 1, a silo 7 is supported above the bottom plate 3, the silo 7 is a rectangular plate frame formed by two long plates and two short plates connected by screws, and the outer sides of the short plates at both ends of the silo 7 are supported on the bottom plate 3 by two L-shaped supports 5 respectively.

[0028] A feeding sleeve 8 is sleeved on the upper opening of the silo 7 and fixed by screws. An upper cover plate 9 is fixed to the upper end of the feeding sleeve 8 by tightening screws. A plurality of 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 installed on the bottom plate 3 below the silo 7 through two symmetrically arranged slide rails 4 and sliders. The feeding plate 2 is attached to the lower port of the silo 7 and can block the lower port of the silo 7 when sliding to the front and rear stop points. A plurality of groups of feed holes 201 are evenly distributed on the feeding plate 2 along the length direction of the silo 7. This embodiment takes six groups of feed holes 201 as an example; Figure 7 As shown, each group of feeding holes 201 is composed of multiple arrow-shaped waist-shaped long strip holes arranged at equal intervals. In this embodiment, nine long strip holes are taken as an example. The arrangement direction of the multiple long strip holes is perpendicular to the arrangement direction of the multiple groups of feeding holes 201, and is used to drop the pill material to be loaded.

[0030] A rectangular material support plate 6 is fixed on the bottom plate 3 below the material bin 7 through a plurality of evenly distributed shims. The material support plate 6 is attached to the bottom surface of the feed plate 2 and slidably cooperates with the feed plate 2 to block the feed hole.

[0031] A rectangular discharge port 701 is provided at the lower end of a long plate on one side of the silo 7. A scrub brush 20 is fixed by screws on the inner side of the discharge port 701 on the long plate. A baffle plate 22 is provided on the outer side of the discharge port 701 on the long plate. The lower ends of the scrub brush 20 and the baffle plate 22 are close to the upper surface of the feed plate 2, and are used to scrape excess material away from the discharge hole 201 when the feed plate 2 is feeding. A baffle cover 10 is fixed by fixing screws on the outer side of the discharge port 701 of the silo 7. The baffle plate 22 is a silicone plate and is fixed in the baffle cover 10 by screws. Waist-shaped holes are provided on the baffle cover 10 corresponding to the fixing screws to facilitate the adjustment of the height of the baffle plate 22.

[0032] A driving device is provided on the frame 1 at one side of the discharge port 701 of the silo 7, and the output end of the driving device is connected to the feeding plate 2 to drive the feeding plate 2 to slide back and forth to achieve quantitative feeding. The long hole arrow of each group of discharge holes 201 points to the side of the driving device.

[0033] A hopper support plate 21 is fixed on the bottom plate 3 at one side of the discharge port 701 of the silo 7, and a plurality of lower hoppers 19 are evenly welded on the hopper support plate 21 and correspond one to one with the plurality of groups of discharge holes 201. The upper portion of the lower hopper 19 is a square cone and the lower portion is a circular tube. The upper end of the lower hopper 19 is in close contact with the edge of one side of the material support plate 6, and is used to guide the pill material delivered by the feeding plate 2.

[0034] The driving device includes a servo motor 15 and a reducer 16 connected to each other. A driving shaft 18 is connected to the output end of the reducer 16. The driving shaft 18 is rotatably mounted on the frame 1 through a sleeve 17 and a bearing fixed on the frame 1. One end of the driving shaft 18 is inserted into the center hole of the output end of the reducer 16. A turntable 13 is fixed to the other end of the driving shaft 18. A stepped chute is radially provided on the turntable 13 and a position-adjustable short shaft 14 is installed in the chute. The large end of the short shaft 14 is a flat head and is inserted into the chute through clearance fit. The short shaft is fixed to the turntable 13 through a nut. A length-adjustable connecting rod 12 is hinged on the short shaft 14. The other end of the connecting rod 12 is hinged to a pin 11 fixed on the feed plate 2. In order to adjust the sliding stroke of the feed plate 2, each group of discharge holes 201 moves to the top of the corresponding discharge hopper 19 when the feed plate 2 slides to the front end, thereby realizing discharge.

[0035] During operation, the pill material to be loaded is added into the silo 7 through the feeding port; the servo motor 15 is started, and the drive shaft 18 is driven to rotate through the reducer, thereby driving the turntable 13 to rotate at a low speed; when the turntable 13 rotates, the feed plate 2 is pulled by the connecting rod 12 to slide back and forth along the slide rail at a uniform speed; when the multiple groups of discharge holes 201 on the feed plate 2 slide into the silo 7, the pill materials in the silo 7 fall into the multiple long holes of each group of discharge holes 201 respectively; as the feed plate 2 slides forward, the excess material can be scraped away from the discharge holes 201 by the plate brush 20 and the baffle plate 22. When the multiple groups of discharge holes 201 on the feed 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.
