[0025] Example 1

[0026] Embodiment 1 of the utility model is an automatic stacking device for Chinese herbal medicine slices, wherein a feed box 2 is arranged on the top of the device body 1, and an inlet 20 and an outlet 21 are respectively arranged on the top and bottom of the feed box 2, and the outlet 21 is provided with a solenoid valve 22, and a stacking assembly 3 is arranged below the outlet 21, and the stacking assembly 3 includes a conveyor belt 31 connected to a conveying roller 30, and a plurality of stacking boxes 33 are arranged on the surface of the conveyor belt 31, and a weighing sensor 6 is arranged on the inner bottom of the stacking box 33, and an infrared sensor 5 is arranged on the bottom of the outlet 21, and a PLC controller 7 is arranged on the outside of the device body 1, and the PLC controller 7 is electrically connected to the weighing sensor 6, the infrared sensor 5 and the solenoid valve 22, respectively, and a filling lower hopper 4 is arranged on the left side of the conveyor belt 31.

[0027] Reference Figure 1 The Chinese herbal medicine pieces to be stacked enter the feeding box 2 through the feed port 20 for collection, and then are discharged through the discharge port 21 for stacking. The infrared sensor 5 is used to monitor whether the discharge port 21 and the stacking box 33 above the conveyor belt 31 are in the same axial position. When they are in the same axial position, the solenoid valve 22 is controlled to open for the Chinese herbal medicine pieces to fall from the discharge port 21 to the inside of the stacking box 33. At the same time, a weighing sensor 6 is arranged inside the stacking box 33. The weighing sensor 6 transmits the weight information of the Chinese herbal medicine pieces inside the stacking box 33 to the PLC controller 7. The PLC controller 7 then compares this weight with the required stacking weight, so that the solenoid valve 22 controls the discharge speed of the Chinese herbal medicine pieces, so that the weight of the Chinese herbal medicine pieces in the final stacking meets the requirements.

[0028] It should be noted that the PLC controller 7 will also control the rotation speed and switch of the conveyor roller 30. During the discharging process, the PLC controller 7 will control the conveyor roller 30 to close, so that the stacking box 33 is stationary on the surface of the conveyor belt 31 to discharge the material, so as to avoid the movement of the stacking box 33 during discharging and cause the Chinese herbal medicine pieces to fall. After the stacking is completed, the weighing sensor 6 transmits the weight information to the PLC controller 7, and the PLC controller 7 restarts the transmission of the stacking box 33. The Chinese herbal medicine pieces loaded in the stacking box 33 are transmitted to the position of the sub-packaging lower hopper 4 on the left side, and the Chinese herbal medicine pieces inside it fall into the sub-packaging lower hopper 4 for subsequent packaging operations, and then the empty stacking box 33 continues to be transmitted. When it is transmitted to the bottom of the conveyor belt 31, the debris inside the stacking box 33 will fall to the bottom of the device body 1 for collection, which is convenient for emptying the inside of the stacking box 33 to reduce the impact of the next stacking of Chinese herbal medicine pieces.

[0029] In some preferred embodiments, a plurality of bases 32 are provided on the surface of the conveyor belt 31, and a convex groove 320 is provided in the base 32. A penetration plate 330 is provided at the bottom of the stacking box 33, and the penetration plate 330 penetrates into the convex groove 320. Springs 321 fixedly connected to the connecting plate 322 are provided on both sides of the convex groove 320. The spacing between adjacent bases 32 is greater than the horizontal length of the base 32.

[0030] Reference Figure 2 The base 32 can be used to insert a plurality of stacking boxes 33 of different specifications under the condition of ensuring stacking, thereby improving the utilization rate of the base 32. A convex groove 320 is mainly arranged in the base 32, and a spring 321 and a connecting plate 322 arranged in the convex groove 320 are used for inserting plates 330 of different specifications. The inserting plate 330 is located in the convex groove 320 to fix the stacking box 33, and the assembly is stable during the discharging process.

[0031] Moreover, the spacing between the adjacent bases 32 is greater than the horizontal length of the base 32, which mainly provides conditions for transferring the Chinese herbal medicine pieces in the stacking box 33 to the sub-packaging lower hopper 4, and avoids the mixing of Chinese herbal medicine pieces in other stacking boxes 33 due to too small spacing, resulting in uneven weight of subsequent packaging. At the same time, the height of the right and left sides of the sub-packaging lower hopper 4 gradually becomes lower, which is conducive to shielding the Chinese herbal medicine pieces on the right side, thereby preventing the Chinese herbal medicine pieces from flying out.

[0032] Example 2

[0033] The difference between this embodiment 2 and embodiment 1 is that the stacking box 33 includes a first U-shaped plate 331 and a second U-shaped plate 332, both sides of the second U-shaped plate 332 penetrate into both sides of the first U-shaped plate 331, and the surface of the second bottom plate 3321 of the second U-shaped plate 332 slides on the bottom surface of the first bottom plate 3312 of the first U-shaped plate 331.

[0034] Reference Figure 3 and Figure 4 The stacking box 33 is composed of a first U-shaped plate 331 and a second U-shaped plate 332, and the second U-shaped plate 332 penetrates into the first U-shaped plate 331, thereby driving the second bottom plate 3321 to slide in the first bottom plate 3312. A suitable accommodating space can be selected according to the volume of the required Chinese herbal medicine pieces, thereby improving the multiple uses of the stacking box 33.

[0035] In some preferred embodiments, first slide grooves 3310 are provided on both sides of the first U-shaped plate 331, and stopper plates 3320 are provided on both sides of the second U-shaped plate 332. The aperture of the end of the first slide groove 3310 close to the second U-shaped plate 332 is smaller than that of the end away from the second U-shaped plate 332. The surface of the second bottom plate 3321 is provided with a convex strip 3322, and the bottom surface of the first bottom plate 3312 is provided with a second slide groove 3311, and the convex strip 3322 is located in the second slide groove 3311.

[0036] Specifically, by setting the first slide groove 3310, the two ends of the second U-shaped plate 332 can move in the first slide groove 3310. Since the insertion end of the first slide groove 3310 is smaller than the width of the limit plate 3320, the limit plate 3320 can be better limited in the first slide groove 3310 to avoid separation. Therefore, the convex strip 3322 of the second bottom plate 3321 moves in the second slide groove 3311 of the first bottom plate 3312, expanding or reducing the space of the entire stacking box 33, so that the space of the stacking box 33 and the size of the evenly divided Chinese medicine guide slices are matched with each other, thereby improving the utilization rate of the device.

[0037] In some preferred embodiments, the weighing sensor 6 is located at the center of the first bottom plate 3312, and further includes a motor 34, which is respectively connected to the conveying roller 30 and the PLC controller 7. The weighing sensor 6 is located at the center of the first bottom plate 3312 to facilitate real-time detection of the weight inside the stacking box 33. At the same time, the motor 34 is arranged to drive the conveying roller 30 to open or close or adjust the conveying speed under the action of the PLC controller 7, so as to realize automatic stacking and improve the stacking efficiency.

[0038] The working principle of the device is that after the preset value of the weighing sensor 6 is set by the PLC controller 7 according to the required stacking weight, the Chinese herbal medicine pieces are fed into the feeding box 2 through the inlet 20. When the infrared sensor 5 detects that the stacking box 33 and the discharge port 21 are on the same axis, the motor 34 stops the driving roller at the same time. After the stacking box 33 is in a stationary state, the PLC controller 7 drives the solenoid valve 22 to start the discharge of the Chinese herbal medicine pieces. When the number of Chinese herbal medicine pieces in the stacking box 33 meets the requirements, the weighing sensor 6 transmits this information to the PLC controller 7, and the PLC controller 7 drives the motor 34 to drive the conveyor roller 30 to drive the conveyor belt 31 to work again, so as to realize intermittent discharge. When the stacking box 33 loaded with Chinese herbal medicine pieces moves to the position of the sub-packaging lower hopper 4, the Chinese herbal medicine pieces fall into it for subsequent packaging operations. The utility model sets a PLC controller 7 and a discharge port 21 driving a solenoid valve 22 to control the discharge speed in the device body 1, an infrared sensor 5 makes the discharge port 21 and the stacking box 33 on the same axis, a weighing sensor 6 is used for quantitative determination in the stacking box 33, and a conveyor belt 31 is driven by a motor 34 to be transmitted to the sub-packaging lower hopper 4 for packaging after stacking, so as to realize intermittent discharge and transmission, complete quantitative stacking and packaging, and achieve high stacking efficiency. At the same time, a base 32 is set on the surface of the conveyor belt 31 to adapt to the insertion plate 330 of the stacking boxes 33 of different specifications, and the second U-shaped plate 332 in the stacking box 33 is telescopic in the first U-shaped plate 331 to expand or reduce the entire stacking box 33 space, thereby improving the reuse rate of the device.

[0039] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
