Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical preparation dispensing technology, and in particular to a veterinary drug preparation dispensing device. Background Technology

[0002] According to the patent document with publication number CN 221938691 U, the drug preparation enters the metering tank through the feeding tank. The first forward and reverse motor drives the metering roller to rotate so that the metering tank coincides with the discharge tank, and the drug preparation enters the filling box through the drug guide plate. The second forward and reverse motor drives the threaded column to move the metering roller left and right until the metering tank of the appropriate size corresponds with the feeding tank and the discharge tank, thus completing the metering size adjustment of the dispenser.

[0003] The patent document states that when adjusting the dispensing volume of a drug formulation, the length of the entire metering roller is limited, and the number of metering slots that can be opened on the metering roller is also relatively limited. Therefore, it is obviously very troublesome to simply rely on switching different metering slots to achieve different dispensing volumes. At the same time, if the length of the metering roller is longer, the downward gravity at its middle position will be greater, which will aggravate the wear between the outer shell, connecting rod, second slider, threaded column, and threaded tube. This will cause friction between the metering roller and the shell, increasing the gap and allowing the drug to enter the space between them, resulting in waste. In addition, when the drug falls at the feed chute, if the drug particles are small or in powder form, it may clog the feed chute, resulting in different drug dosages each time. Utility Model Content

[0004] The purpose of this invention is to provide a veterinary drug preparation dispenser in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A veterinary drug preparation dispenser includes a support frame, a conveying mechanism inside the support frame, multiple packaging guide plates on the conveying mechanism, a packaging fixing pin fixed at the upper end of each packaging guide plate, and a drug guiding mechanism and a dispensing mechanism.

[0007] The drug delivery mechanism includes a packaging funnel. Two symmetrical impact rods are slidably connected to the lower end of the packaging funnel. A toothed frame is provided at the end of the two impact rods that are close to each other. Teeth are provided at both ends of the toothed frame to push the ends of the impact rods. A return spring is fixed at the end of the two impact rods that are far from each other. Two impact balls are fixed on each impact rod. A movable cavity is provided at the lower end of the packaging funnel to allow the impact balls to move.

[0008] The dispensing mechanism includes a limiting frame, a dispensing frame slidably connected inside the limiting frame, an adjusting frame slidably connected to one side of the dispensing frame, an adjusting screw rotatably connected to the middle position of the adjusting frame, four dispensing slots on the dispensing frame, a connecting shaft fixed at the middle position of the top of the dispensing frame, a connecting rod hinged to one end of the connecting shaft passing through the toothed frame, a crank hinged to the end of the connecting rod away from the connecting shaft, and a drive motor for driving its rotation is provided on the upper side of the crank.

[0009] Preferably, the middle position of the dispensing frame has a threaded hole for cooperating with the adjusting screw, and a vertical plate is fixed at one end of the dispensing slot of the adjusting frame.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figures 1-12 As shown, a veterinary drug preparation dispenser includes a support frame 3, a conveying mechanism 4 inside the support frame 3, a plurality of packaging guide plates 5 on the conveying mechanism 4, a packaging fixing pin 6 fixed at the upper end of each packaging guide plate 5, and also includes a drug guiding mechanism 1 and a dispensing mechanism 2.

[0035] In this embodiment: the drug delivery mechanism 1 includes a packaging funnel 11. Two symmetrical impact rods 12 are slidably connected to the lower end of the packaging funnel 11. A toothed frame 15 is provided at the end of the two impact rods 12 that is close to each other. The toothed frame 15 has teeth at both ends for pushing the ends of the impact rods 12. A return spring 13 is fixed at the end of the two impact rods 12 that is far from each other. Two impact balls are fixed on each impact rod 12. A movable cavity 14 for moving the impact balls is provided at the lower end of the packaging funnel 11. Four outlet tubes are provided at the lower end of the packaging funnel 11. Each outlet tube has a sliding hole for sliding the impact rods 12 back and forth. The veterinary drug preparation is introduced into the dispensing mechanism 2 through the four outlet tubes of the packaging funnel 11. In addition, the reciprocating movement of the toothed frame 15 is used to alternately push the ends of the two impact rods 12. Then, the impact balls on the impact rods 12 slide back and forth in the movable cavity 14, and then vibration is generated at the outlet tube to accelerate the fall of the entire veterinary drug preparation, so as to avoid the solid veterinary drug preparation from clogging and affecting the dispensing accuracy.

[0036] In this embodiment: the dispensing mechanism 2 includes a limiting frame 29, a dispensing frame 23 is slidably connected inside the limiting frame 29, an adjusting frame 21 is slidably connected to one side of the dispensing frame 23, an adjusting screw 22 is rotatably connected to the middle position of the adjusting frame 21, four dispensing slots 25 are provided on the dispensing frame 23, a connecting shaft 24 is fixed at the middle position of the top of the dispensing frame 23, a connecting rod 26 is hinged to one end of the connecting shaft 24 passing through the toothed frame 15, a crank 27 is hinged to the end of the connecting rod 26 away from the connecting shaft 24, a drive motor 28 for driving the crank 27 to rotate is provided on the upper side of the crank 27, a threaded hole for cooperating with the adjusting screw 22 is provided at the middle position of the dispensing frame 23, a vertical plate 211 is fixed at one end of the adjusting frame 21 located in the dispensing slot 25, four medicine dispensing slots 291 corresponding to the outlet tube are provided on one side of the top of the limiting frame 29, a guide groove 293 is provided at the middle position of the top of the limiting frame 29, and a guide groove 293 for the drive motor 28 is fixed at the other side of the top of the limiting frame 29. The supporting motor bracket has four medicine dispensing slots 292 on one side of the bottom of the limiting frame 29. A socket for inserting the packaging fixing pin 6 is located on the lower side of the other end of the limiting frame 29. The rotating part of the drive motor 28 drives the crank 27 to rotate, and as the crank 27 rotates, the connecting rod 26 drives the connecting shaft 24 and the dispensing frame 23 to slide back and forth along the guide groove 293 of the limiting frame 29. When the dispensing slot 25 of the dispensing frame 23 moves to the position of the medicine dispensing slot 292... After the corresponding position is reached, the veterinary drug preparation in the packaging funnel 11 will fall from the inside of the outlet tube and through the drug outlet 291 into the dispensing tank 25. As the dispensing rack 23 continues to move, the drug outlet 291 is blocked by the top of the adjusting rack 21. Then, the dispensing rack 23 drives the adjusting rack 21 to continue to move. The dispensing tank 25 of the dispensing rack 23 corresponds to the drug outlet 292. At this time, the veterinary drug preparation in the dispensing tank 25 will fall out from the drug outlet 292 for dispensing.

[0037] In this embodiment: the conveying mechanism 4 includes a conveyor belt 42, and conveying rollers 41 for driving the conveyor belt 42 to rotate are provided on both sides of the conveyor belt 42. A conveying motor 43 for driving the conveying rollers 41 to rotate is fixed on the front side of the support frame 3. The conveying motor 43 drives the conveying rollers 41 at its rear end to rotate. The rotation of the conveying rollers 41 drives the conveyor belt 42 and the packaging box on its upper side to move to one side. When the packaging box on the conveyor belt 42 is below the drug outlet 292, the movement of the packaging box stops. When the veterinary drug preparation falls into the packaging box, the conveyor belt 42 starts to move to one side again.

[0038] Working principle: When in use, first adjust the position of the packaging guide plate 5 on the limit frame 29 according to the size of the packaging box, and insert the packaging fixing pin 6 on the packaging guide plate 5 into the corresponding insertion hole of the limit frame 29. Then, place the packaging box between the packaging guide plates 5 on the front and rear sides of the medicine outlet 292, and drive the conveyor roller 41 at its rear end to rotate through the rotating part of the conveyor motor 43. The rotation of the conveyor roller 41 drives the conveyor belt 42 and the packaging box on its upper side to move to one side.

[0039] In addition, rotating the adjusting screw 22 allows it to be screwed into or out of the threaded hole of the dispensing frame 23 a certain distance. Then, the adjusting screw 22 will synchronously drive the adjusting frame 21 to move. When the adjusting frame 21 moves, it drives the vertical plate 211 to slide in the dispensing slot 25, thereby expanding or reducing the capacity of the entire dispensing slot 25 to fill veterinary drug preparations.

[0040] When the packaging box on the conveyor belt 42 moves to below the drug outlet 292, the veterinary drug preparation to be dispensed is poured into the packaging funnel 11. The rotating part of the drive motor 28 drives the crank 27 to rotate, and when the crank 27 rotates down, the connecting rod 26 drives the connecting shaft 24 and the dispensing frame 23 to slide back and forth along the guide groove 293 of the limit frame 29.

[0041] As the dispensing rack 23 moves along the inner side of the limiting frame 29 to the other side, when the dispensing slot 25 of the dispensing rack 23 moves to the position corresponding to the drug dispensing slot 291, the veterinary drug preparation in the packaging funnel 11 will fall from the inside of the outlet tube and through the drug dispensing slot 291 into the dispensing slot 25. As the dispensing rack 23 continues to move, the drug dispensing slot 291 is blocked by the top of the adjusting frame 21. Then, the dispensing rack 23 drives the adjusting frame 21 to continue moving, and the dispensing slot 25 of the dispensing rack 23 corresponds to the drug dispensing slot 292. At this time, the veterinary drug preparation in the dispensing slot 25 will fall from the drug dispensing slot 292 into the packaging box.

[0042] In addition, during this process, the toothed frame 15 will move to the other side of the limiting frame 29 along with the connecting shaft 24. At this time, the teeth on the front and rear sides of the toothed frame 15 will be used to push the ends of the two impact rods 12 alternately. At the same time, the two return springs 13 will be used to push the impact rods 12 to return to their original positions. Then, the impact ball on the impact rod 12 will slide back and forth in the active cavity 14 to impact the impact, and then generate vibration at the outlet tube to accelerate the fall of the entire veterinary drug preparation, so as to avoid the solid veterinary drug preparation from clogging and affecting the dispensing accuracy.

[0043] When the dispensing rack 23 moves to the other end of the limiting rack 29, the veterinary drug preparation in the dispensing tank 25 falls completely out of the dispensing tank opening 292. As the crank 27 continues to rotate, the dispensing rack 23 is reset to one side through the connecting rod 26 and the connecting shaft 24, and then the next dispensing process is repeated. At the same time, the conveyor belt 42 continues to rotate to move the packaged box that has been dispensed to one side, and then the next packaged box is placed on the conveyor belt 42.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
