[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a quantitative weighing device for packaging Chinese herbal medicine slices, comprising a shell 1, a fixed plate 3 is fixedly connected to the rear side of the shell 1, a blower 4 is fixedly connected to the left side of the top wall of the fixed plate 3, an extraction end of the blower 4 is connected to a filter box 5, an adsorption sponge 6 is fixedly installed on the inner wall of the filter box 5, an output end of the blower 4 is connected to a delivery pipe 7, a top end of the delivery pipe 7 is connected to a porous nozzle 8, an outer wall of the porous nozzle 8 is fixedly connected to the inner wall of the shell 1, an electric telescopic rod 10 is rotatably connected to the rear side of the inner wall of the shell 1, a displacement block 11 is fixedly connected to the output end of the electric telescopic rod 10, and a displacement block 11 is fixedly connected to the output end of the electric telescopic rod 10. The top wall is fixedly connected with a rotating member 12, the top wall of the rotating member 12 is fixedly connected with a weighing plate device 13, the left and right sides of the weighing plate device 13 are fixedly connected with rotating columns 14, the far-away sides of the two rotating columns 14 are respectively fixedly connected to the left and right sides of the inner wall of the shell 1, and the left and right sides of the middle of the rear side of the inner wall of the shell 1 are provided with scraping components, the scraping components include two return springs 15, the rear ends of the two return springs 15 are fixedly connected to the left and right ends of the rear side of the inner wall of the shell 1, the front sides of the two return springs 15 are fixedly connected with scrapers 16, the middle of the rear side of the scraper 16 is fixedly connected with a push rod 17, and the top wall of the shell 1 is rotatably connected with a movable plate 22;

[0032] Specifically, the blower 4 inhales the outside air through the filter box 5 and then filters the air. When the air passes through the filter box 5, the adsorption sponge 6 will adsorb the water vapor therein. In this way, the treated airflow will become dry. The dry airflow then passes through the conveying pipe 7 and enters the porous nozzle 8 for spraying. In this way, the airflow can flow inside the housing 1, avoiding the attachment of water vapor to the top wall of the weighing plate device 13, thereby cleaning the weighing plate device 13. The airflow will blow out the particles remaining on the top wall of the weighing plate device 13. Thereby reducing the risk of errors in the weighing data. Push the push rod 17 so that the scraper 16 can scrape off the particles on the top wall of the weighing plate device 13. In this process, the two reset springs 15 can ensure that the scraper 16 can be smoothly reset after completing the scraping task. Once the weighing is completed, the electric telescopic rod 10 will drive the displacement block 11 to move backward. At this time, the rotating member 12 begins to play a role, causing the weighing plate device 13 to tilt downward through the rotation of the rotating column 14. The Chinese herbal medicine slices slide down under the force of gravity and the angle of inclination and are collected.

[0033] Reference Figure 1 and Figure 3The bottom wall of the housing 1 is provided with a rotating mechanism 2, which includes a connecting plate 201, the left side of the connecting plate 201 is fixedly connected to the right side of the displacement block 11, the bottom wall of the connecting plate 201 is fixedly connected with a tooth seat 202, a displacement groove 206 is provided on the right side of the inner bottom wall of the housing 1, the middle part of the connecting plate 201 is slidably connected with the displacement groove 206, the bottom wall of the housing 1 is rotatably connected with a gear column 203, the gear column 203 is meshed with the tooth seat 202, the left side of the gear column 203 is fixedly connected with a rotating plate 204, and a clamping groove 205 is provided on the left side of the top wall of the rotating plate 204;

[0034] Specifically, the displacement block 11 achieves synchronous backward movement of the connecting plate 201 by displacing backward. The key to this process lies in the design of the displacement groove 206, which enables the connecting plate 201 to slide smoothly in the groove, thereby driving the gear seat 202 to move. This design fully reflects the accuracy and reliability of mechanical transmission. Next, the meshing connection between the gear seat 202 and the gear column 203 enables the gear column 203 to rotate counterclockwise. This innovative design not only improves the operating efficiency of the equipment, but also reduces the failure rate. The rotation of the gear column 203 drives the rotating plate 204 to rotate forward, realizing efficient power transmission. Through the design of the engaging groove 205, the collection box can be accurately engaged. After completing the weighing, the equipment can automatically collect the Chinese herbal medicine slices, reducing the labor cost of the operator.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A control switch 18 is fixedly connected to the top of the left side of the housing 1, and the control switch 18 is electrically connected to the blower 4 and the electric telescopic rod 10 respectively; a protective shell 19 is provided on the left side of the control switch 18, and the right side of the protective shell 19 is rotatably connected to the left side of the housing 1 through a hinge; an inclined surface is provided on the front side of the displacement block 11, and a groove is provided on the top wall of the weighing plate device 13;

[0036] Specifically, the control switch 18 can open and close the device through the control switch 18 electrically connected to the blower 4 and the electric telescopic rod 10 respectively, and the protective shell 19 can protect the control switch 18 and prevent accidental touch.

[0037] Reference Figure 2 A rubber ring 9 is fixedly installed on the outer wall of the delivery pipe 7, and the front side of the outer wall of the rubber ring 9 is fixedly connected to the rear side of the porous nozzle 8; the left and right sides of the shell 1 and the left and right ends of the rear side of the fixing plate 3 are fixedly connected with L-shaped plates 20, and the inner walls of the multiple L-shaped plates 20 are fixedly connected with support columns 21;

[0038] Specifically, the rubber ring 9 can protect the connection between the delivery pipe 7 and the porous nozzle 8, thereby reducing the wear of the connection. The L-shaped plate 20 and the plurality of support columns 21 make the device more stable during operation.

[0039] Working principle: When starting to use, turn on the blower 4. The blower 4 draws the outside air through the filter box 5, and the airflow is filtered through the filter box 5, so that the adsorption sponge 6 inside the filter box 5 can adsorb the water vapor contained in the extracted airflow, so that the dry airflow passes through the conveying pipe 7 and is sprayed via the porous nozzle 8, so that the airflow flows inside the shell 1, so as to blow out the residual particles on the top wall of the weighing plate device 13, avoiding the attachment of water vapor to the top wall of the weighing plate device 13 and the reaction to the medicine slices, thereby reducing the error in the weighing data, and by pushing the push rod 17, the scraper 16 can scrape off the particles attached to the top wall of the weighing plate device 13, and the scraper 16 can be reset by two reset springs 15. After the weighing is completed, The displacement block 11 is driven by the electric telescopic rod 10 to move backward, so that the weighing plate device 13 is tilted downward by the rotation of the rotating member 12 through the rotation of the rotating column 14, so that the Chinese herbal medicines are collected by sliding down under the gravity and the tilt angle, and the backward displacement of the displacement block 11 causes the connecting plate 201 to move backward synchronously, so that the connecting plate 201 slides in the displacement groove 206, thereby driving the gear seat 202 to move. Since the gear seat 202 is meshed and connected with the gear column 203, the gear column 203 rotates counterclockwise, and then the rotating plate 204 rotates forward, and then the collection box can be engaged through the engaging groove 205, so as to achieve the purpose of automatically collecting the Chinese herbal medicines after weighing, thereby reducing the labor cost of the operator.
