Description

Technical Field

[0001] This utility model belongs to the field of powdered drug packaging, and in particular relates to a fully automatic powdered veterinary drug packaging device. Background Technology

[0002] After the powdered veterinary drugs are prepared, the powder in the storage tank or trough needs to be packaged. To improve the packaging accuracy, the commonly used method is to place the packaging hopper on a weighing platform, with a valve installed at the outlet of the storage tank or trough. When the valve is opened, the powder enters the hopper, and the weighing platform weighs the powder in the hopper. When the weight of the powder in the hopper meets the packaging requirements, the valve at the outlet of the storage tank or trough is closed, and the powder in the hopper is then discharged into packaging bottles or bags, completing the packaging. However, in this conventional packaging structure, the lag caused by the complete closure of the outlet of the storage tank or trough often results in the discharge volume from the storage tank exceeding the packaging set amount. This means that the weight of the powder in the hopper exceeds the packaging requirements, resulting in a packaging weight deviation and low packaging accuracy. Utility Model Content

[0003] In view of this, the present invention aims to propose a fully automatic powder veterinary drug dispensing device to achieve precise dispensing of veterinary drug powder.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, a fully automatic powder veterinary drug dispensing device includes a platform 1, a weighing plate 5, a hopper 4, and a storage tank 10. The hopper 4 is directly opposite the discharge port of the storage tank 10 and is used to receive powdered veterinary drugs from the storage tank 1. Four weighing sensors 11 are installed on the upper surface of the platform 1, and the weighing plate 5 is fixed on the four weighing sensors 11. The hopper 4 is fixed on the weighing plate 5 through a weighing connecting frame 6.

[0026] The bottom plate 41 of the hopper 4 is inclined, and the discharge port 43 of the hopper 4 is opened on the side wall of the hopper 4, and the discharge port 43 corresponds to the lower end of the bottom plate 41. The outer wall of the hopper 4 is provided with a discharge pipe 2 at the position of the discharge port 43. The discharge pipe 2 is inclined and the inclination direction corresponds to the inclination direction of the bottom plate 41. If the weight of the veterinary drug powder in the hopper 4 meets the packaging requirements, it is discharged into the packaging bottle or packaging bag through the discharge pipe 2. The discharge pipe 2 is equipped with a slide valve 3, preferably a pneumatic slide valve. The base plate 41 has a first discharge hole 42. A turntable 8 is installed on the bottom surface of the base plate 41. The top surface of the turntable 8 is in contact with the bottom surface of the base plate 41. The turntable 8 is driven by a motor 12. A spring plug 9 is set on the turntable 8 facing the first discharge hole 42. The spring plug 9 includes a plug 91 and a spring 92. The plug 91 is inserted into the first discharge hole 42 to seal the first discharge hole 42, so as to prevent the powder in the hopper 4 from accumulating in the first discharge hole 42 or from spilling out of the first discharge hole 42.

[0027] In this utility model, the slide valve 3, motor 12, weighing sensor 11, and valve at the outlet of storage tank 10 are electrically connected to the controller. Spring plug 9 blocks the first discharge hole 42 to prevent the veterinary powder in hopper 4 from being lost through the first discharge hole 42. When the weight of the veterinary powder in hopper 4 is qualified and meets the packaging requirements, the valve at the outlet of storage tank 10 is closed, the slide valve 3 is opened, and the veterinary powder in hopper 4 is discharged through discharge pipe 2 into packaging bottles or packaging bags, realizing the packaging of veterinary powder after production.

[0028] In this utility model, the structure of the turntable 8 is as follows: Figure 3 As shown, a second discharge hole 81 and a guide hole 82 are provided on it. The second discharge hole 81 is adjacent to the guide hole 82. The distances from the second discharge hole 81, the guide hole 82, and the first discharge hole 42 to the center of the turntable are the same. The spring plug 9 is set at the position of the guide hole 82.

[0029] Spring plug 9 installation and sealing structure for the first discharge hole, as follows Figure 4 As shown, the bottom of the turntable 8 is provided with a mounting cavity 83 directly opposite the guide hole 82. The spring 92 of the spring plug 9 is located in the mounting cavity 83. The plug 91 passes through the guide hole 82 and is inserted into the first discharge hole 42 to seal the first discharge hole 42.

[0030] The plug 91 structure is as follows Figure 5 As shown, the spring plug 911 includes a sealing part 913, a guide part 912, and an outer edge part 911 arranged sequentially from top to bottom, and the top surface of the plug 91 is a spherical structure 914. The spring plug 911 blocks the first material discharge hole in the following state: the outer edge part 911 is located in the mounting cavity 83, the guide part 912 is correspondingly arranged with the guide hole 82 and is slidably connected to the guide hole 82, the sealing part 913 is correspondingly arranged with the first material discharge hole 42, and the sealing part 913 extends out of the first material discharge hole 42 to block the first material discharge hole 42. To improve the sealing effect of the plug on the first discharge hole 42, in this utility model, the first discharge hole 42 is a conical hole with the large end facing downwards, and the circumferential surface of the plugging part 913 is a conical surface structure corresponding to the conical hole. The plugging part 913 and the hole wall of the first discharge hole 42 form a conical sealing structure, and the upper end of the plugging part 913 extends out of the first discharge hole 42, thereby improving the sealing effect of the first discharge hole 42 and ensuring that the powder in the hopper 4 is completely discharged.

[0031] This utility model also includes a weight-reducing structure. When the weight of the powder in the hopper 4 exceeds the required dispensing weight, the excess powder is removed using the weight-reducing structure. Figure 2 As shown, the turntable 8 includes a second discharge hole 81. When excess powder needs to be removed, the turntable 8 rotates until the second discharge hole 81 and the first discharge hole 42 are connected. The powder in the hopper 4 leaks out through the first discharge hole 42 and the second discharge hole 81, thus reducing the weight of the powder. At this time, the spring plug 9 moves away from its initial position and retracts into the guide hole 82, with its top abutting against the bottom plate 41. The weighing plate 5 has a through groove 51 corresponding to the first discharge hole 42, which penetrates the upper and lower surfaces of the weighing plate 5. A bracket is installed in the through groove 51 and mounted on the platform 1. A collection bucket 7 is placed on the bracket, corresponding to the second discharge hole 81. The leaked powder is collected by the collection bucket 7. The weight-reducing structure removes the powder from the hopper and reduces its weight until the weight of the powder in the hopper meets the packaging requirements. Then, the turntable 8 rotates back until the spring plug 9 blocks the first discharge hole 42, and the hopper discharges the powder, completing the packaging of the veterinary drug powder.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
