Abstract
Description
Technical Field
[0001] This utility model relates to the field of veterinary drug packaging equipment technology, and in particular to a quantitative bottle feeding device for veterinary drug filling. Background Technology
[0002] After veterinary drugs are processed, they need to be filled into veterinary drug bottles using filling equipment. Existing filling equipment generally uses a conveyor belt to transport empty veterinary drug bottles to the filling station, fill them, and then transport the bottles away. In order to improve filling efficiency, existing filling equipment usually has multiple filling heads to fill a group of veterinary drug bottles at the same time. This requires the veterinary drug bottles to pass through the filling equipment in groups and stop at the filling equipment to wait for filling. When workers are loading the bottles, it is difficult to control the distance between the veterinary drug bottles, making it impossible for the veterinary drug bottles to match the filling equipment. Some also use a rotating plate to feed the bottles, but this method moves one veterinary drug bottle to the filling equipment at a time, resulting in a small number of bottles filled at one time, which affects the efficiency of the filling equipment.
[0003] Therefore, a quantitative bottle feeding device for veterinary drug filling is needed to solve the above problems. Utility Model Content
[0004] This utility model proposes a quantitative bottle feeding device for veterinary drug filling. Through a linkage drive structure, the first limit rod and the second limit rod release and block the veterinary drug bottles, so that the veterinary drug bottles enter or leave the filling station in groups, thereby realizing quantitative bottle feeding.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A quantitative bottle feeding device for veterinary drug filling includes a frame, a bottle conveying mechanism on the frame, a filling port on the bottle conveying mechanism, a limit frame hinged to the frame, the limit frame being U-shaped and horizontally positioned above the conveying mechanism, a first limit rod fixedly installed at one end of the limit frame to block the advance of the veterinary drug bottle at the filling port, a second limit rod slidably installed on the frame in the horizontal direction to block the advance of the veterinary drug bottle upstream of the filling port, a cam and a swing arm rotatably mounted on the frame, a cam-shaped guide groove provided at the top of the cam, a tension spring provided between the limit frame and the frame for abutting the other end of the limit frame against the outer peripheral surface of the cam, a connecting rod hinged between the swing arm and the second limit rod, a guide wheel rotatably mounted on the swing arm, the guide wheel being constrained within the guide groove.
[0007] As a preferred technical solution, the guide groove includes a first arc-shaped groove and a second arc-shaped groove. The first arc-shaped groove is disposed at the base circle end of the cam. The radius of the first arc-shaped groove is larger than the radius of the second arc-shaped groove. The two ends of the first arc-shaped groove are respectively connected to the two ends of the second arc-shaped groove through a straight groove.
[0008] As a preferred technical solution, the medicine bottle conveying mechanism includes a driving synchronous pulley and a driven synchronous pulley rotatably mounted on the frame, a conveyor belt is provided between the driving synchronous pulley and the driven synchronous pulley, two baffles are fixedly installed on the frame, both baffles are provided above the conveyor belt, and the veterinary medicine bottle is provided between the two baffles.
[0009] As a preferred technical solution, when the base circle end of the cam abuts against the limiting frame, the guide wheel is disposed in the second arc-shaped groove, and the free ends of the first limiting rod and the second limiting rod move to the space between the two baffles. At the filling point, a set of veterinary drug bottles is blocked between the first limiting rod and the second limiting rod.
[0010] As a preferred technical solution, a support frame is fixedly installed on the frame, and two vertically arranged guide columns are fixedly installed on the support frame. A sliding plate is slidably installed on the two guide columns, and a plurality of filling heads communicating with veterinary drug liquid are provided on the sliding plate. The plurality of filling heads are adapted to a set of veterinary drug bottles at the filling point.
[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0012] Because the quantitative bottle feeding device for veterinary drug filling includes a first limiting rod, a second limiting rod, and a cam, during the use of this device, the first limiting rod can be moved through the cooperation of the cam, tension spring, and limiting frame. The swing arm can be swung through the cooperation of the guide groove and guide wheel. The swing arm, in conjunction with the connecting rod, moves the second limiting rod. This utility model achieves the linkage of the first and second limiting rods through the cam, limiting frame, swing arm, and connecting rod. The movement of the first and second limiting rods can block and release veterinary drug bottles, allowing them to enter or leave the filling area in groups. The first limiting rod blocks the veterinary drug bottles at the filling area, stopping them from moving forward and waiting to be filled. Compared with a rotating disc feeding device, this utility model can allow multiple veterinary drug bottles to enter the filling area at once, enabling the filling equipment to fill multiple bottles of veterinary drugs at once, thus improving filling efficiency.
[0013] Because the cam has a guide groove, during the bottle feeding process, as the cam rotates, the guide wheel moves from the second arc-shaped groove to the first arc-shaped groove, causing the swing plate to swing towards the second limit rod. Under the connection of the connecting rod, the free end of the limit rod extends between the two baffles to block the veterinary drug bottle, thus realizing the conversion of the limit rod from the release state to the blocking state.

The two ends of the first arc-shaped groove 12 are respectively connected to the two ends of the second arc-shaped groove 13 through a straight groove 15.
[0026] The medicine bottle conveying mechanism includes a driving synchronous pulley 17 and a driven synchronous pulley 18 rotatably mounted on the frame 1. A conveyor belt 19 is arranged between the driving synchronous pulley 17 and the driven synchronous pulley 18. Two baffles 20 are fixedly installed on the frame 1. Both baffles 20 are arranged above the conveyor belt 19. The veterinary medicine bottle 4 is arranged between the two baffles 20.
[0027] like Figure 4 As shown, when the base circle end 14 of the cam 6 abuts against the limit frame 3, the guide wheel 11 is set in the second arc-shaped groove 13, and the free ends of the first limit rod 16 and the second limit rod 5 move to the space between the two baffles 20. A set of veterinary medicine bottles 4 is blocked between the first limit rod 16 and the second limit rod 5 at the filling point 2.
[0028] A support frame 21 is fixedly installed on the frame 1. Two vertically arranged guide columns 22 are fixedly installed on the support frame 21. A sliding plate 23 is slidably installed on the two guide columns 22. Several filling heads 24 connected with veterinary drug liquid are provided on the sliding plate 23.

Under the conveying of the conveyor belt 19, the veterinary drug bottle 4 enters the filling area 2 in sequence.
[0034] The second step, as Figure 5 As shown, after a set of veterinary drug bottles 4 enters the filling station 2, the cam 6 rotates, causing the second limit rod 5 to enter the blocking state, blocking the upstream veterinary drug bottles 4. At this time, the first limit rod 16 and the second limit rod 5 limit a set of veterinary drug bottles 4 at the filling station 2, and several filling heads 24 simultaneously fill the set of veterinary drug bottles 4 at the filling station 2.
[0035] The third step, as Figure 6As shown, after filling, the first limiting rod 16 enters the release state, releasing a group of filled veterinary drug bottles 4. At this time, the second limiting rod 5 is still in the blocking state. After all the filled group of veterinary drug bottles 4 have left the filling station 2, the second limiting rod 5 re-enters the release state, allowing the empty veterinary drug bottles 4 to re-enter the filling station and start filling the next group of veterinary drug bottles 4. This process is repeated to achieve quantitative bottle supply of veterinary drug bottles 4.
