Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece processing technology, specifically a traditional Chinese medicine decoction piece intelligent sorting equipment. Background Technology

[0002] As the main form of clinical application of traditional Chinese medicine, the purity and quality of prepared herbal pieces directly affect the safety and efficacy of medication. During the processing of prepared herbal pieces, impurities such as mud, sand, and debris are often mixed in. If these impurities are not treated and directly enter the subsequent sorting and packaging stages, it will not only affect the quality of the finished product, but may also put a burden on or even damage the sorting equipment.

[0003] Color sorters are devices that automatically sort materials based on differences in color or shape, using image recognition and high-speed air jet technology. They are currently widely used in the grading and foreign matter removal processes of traditional Chinese medicine decoction pieces. Typically, materials are conveyed to the color sorter via a feeding structure for identification and sorting.

[0004] However, in actual production, it has been found that if the raw material contains a lot of fine debris or impurities, directly entering the color sorter will not only increase the equipment's recognition burden and affect the sorting accuracy and efficiency, but may also lead to valve blockage and increased equipment failure rate.

[0005] Therefore, we propose an intelligent sorting device for Chinese herbal medicine slices. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an intelligent sorting device for Chinese herbal medicine slices, which has the following beneficial effects:

[0017] 1. This intelligent sorting equipment for Chinese herbal medicine slices, through a pre-treatment structure set at the front end of the color sorter, can effectively remove fine impurities such as mud and sand and debris mixed in with the Chinese herbal medicine materials before they enter the color sorter. This not only reduces the recognition load of the color sorter and improves the accuracy and efficiency of color sorting, but also helps to reduce optical sensor interference and air valve blockage caused by debris, thus reducing the equipment failure rate.

[0018] 2. This intelligent sorting equipment for Chinese herbal medicine slices adopts a pretreatment structure that combines vibration filtration with elastic support. Driven by a vibration motor, and in conjunction with an inclined filter plate and a unique elastic support structure, it achieves efficient filtration of materials in the slag removal box.

[0019] 3. This intelligent sorting equipment for Chinese herbal medicine slices features an elastic support structure composed of guide rings, guide rods, connecting blocks, and spiral springs. This structure not only provides effective vibration support for the slag removal box but also ensures the stability and directionality of the vibration process through the guide rings, avoiding unnecessary lateral swaying. This concentrates vibration energy for material screening, improving screening efficiency. The constant-pressure air holes at the bottom of the support column's sidewall balance the internal air pressure changes during the guide rod's reciprocating motion within the mounting groove, eliminating the damping effect caused by air pressure fluctuations in the confined space. This makes the vibration of the slag removal box smoother, reduces energy loss, and also helps ensure the stability of the spiral spring's damping performance. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-5 As shown, this utility model provides an intelligent sorting device for Chinese herbal medicine slices, including a color sorter 1, a support 2, a feeding structure 3, a slag collection box 4, and a core pretreatment structure 5.

[0028] The support frame 2 is fixed to the rear end of the color sorter 1 to support the various components thereon. The feeding structure 3 is installed at the front of the upper end of the support frame 2 to smoothly convey the pre-treated material to the feed inlet of the color sorter 1. The pre-treatment structure 5 is installed at the rear of the upper end of the support frame 2, located behind the feeding structure 3, and its function is to receive the incoming material and screen and remove impurities from it.

[0029] The pretreatment structure 5 mainly includes a slag removal box 6, four support columns 7, a discharge pipe 9, two vibrating motors 10, a discharge chute 11, four sets of elastic support structures 20, and an inclined filter plate 18.

[0030] The slag removal box 6 is an open-top container used to hold the Chinese herbal medicine slices to be sorted. The lower ends of the four support columns 7 are fixed to the bracket 2, and their upper ends are connected to the four corners of the lower outer surface of the slag removal box 6 through four sets of elastic support structures 20, thereby elastically supporting the slag removal box 6 above the bracket 2. The inclined filter plate 18 is fixedly installed inside the slag removal box 6, and its plate surface is arranged inclined downward from the end away from the feeding structure 3 (rear end) to the end closer to the feeding structure 3 (front end), that is, inclined towards the discharge port 19 opened at the lower front side of the slag removal box 6. The bottom of the inner cavity of the slag removal box 6 is provided with a guide slope 17, which can guide the screened impurities to the middle.

[0031] The upper end of the feed pipe 9 is fixedly installed in the middle of the lower outer surface of the slag removal box 6, and extends upward through the inner cavity of the slag removal box 6, connecting with the lowest point of the guide slope 17, for collecting and discharging impurities. The slag collection box 4 is placed on the bracket 2 and located directly below the feed pipe 9, for receiving impurities falling from the feed pipe 9, facilitating regular cleaning. The discharge chute 11 is fixedly installed on the front side wall of the slag removal box 6 and connected to the discharge port 19, for guiding the filtered clean beverage slices to the feeding structure 3 below it.

[0032] Two vibratory motors 10 are symmetrically fixed on the left and right sides of the lower outer surface of the slag removal box 6. The vibratory motors 10 are preferably high-frequency micro-vibration motors, with a speed range of 2800-3000 rpm. The excitation force can be selected according to the load weight of the slag removal box 6 (e.g., the weight of the fully loaded material is 50 kg), usually between 2 kN and 5 kN, to ensure that the slag removal box 6 and the internal material can be effectively driven to generate high-frequency micro-amplitude vibration.

[0033] Each set of elastic support structures 20 includes a guide ring 13, a guide rod 14, a connecting block 15, and a helical spring 16. The connecting block 15 is fixedly installed on one corner of the lower surface of the slag removal box 6. The upper end of the guide rod 14 is vertically fixedly connected to the lower end face of the connecting block 15. A cylindrical mounting groove 12 is opened on the upper end face of the support column 7. The guide ring 13 is fixedly embedded in the top of the mounting groove 12. The lower part of the guide rod 14 passes through the guide ring 13 and extends into the interior of the mounting groove 12. Its outer wall and the inner wall of the guide ring 13 form a precise sliding pair, thereby constraining the slag removal box 6 to reciprocate only in the vertical direction and preventing harmful lateral swaying. The helical spring 16 is sleeved on the outside of the guide rod 14, and its upper and lower ends are respectively fixed between the lower end face of the connecting block 15 and the upper end face of the support column 7.

[0034] The helical spring 16 is a key component of the elastic support system. Its parameter configuration must match the total mass of the vibration system (including the weight of the slag removal box 6, the weight of the material, and the weight of the vibrating motor 10) and the excitation force of the vibrating motor. As an example, if the total mass of the vibration system is approximately 60 kg and a vibrating motor with an excitation force of 3 kN is selected, the stiffness coefficient k of the helical spring 16 can be selected between 30 N / mm and 50 N / mm. Its rated compression should be greater than the maximum amplitude of the vibrating motor during operation (usually 2-5 mm), and it should ensure an appropriate pre-compression under static load (the weight of the slag removal box 6 and the material) to achieve efficient screening and vibration isolation.

[0035] To further optimize vibration performance, a constant pressure air hole 8 is provided at the bottom of the side wall of the support column 7. One end of the constant pressure air hole 8 is connected to the external atmosphere, and the other end is connected to the bottom of the mounting groove 12. Its function is to balance the air pressure inside the mounting groove 12 when the guide rod 14 reciprocates at high frequency within the mounting groove 12, eliminate damping caused by air pressure changes, make vibration smoother, reduce energy loss, and protect the stability of the helical spring 16.

[0036] The working process of this utility model is as follows:

[0037] An external lifting device pours the raw Chinese herbal medicine slices to be sorted into the rear of the slag removal box 6. Two vibrating motors 10 are started, and the high-frequency vibrations they generate are transmitted to the inclined filter plate 18 inside the slag removal box 6. Under the action of vibration and the inclined plate surface, the material bounces and moves forward continuously. During this process, the slices that meet the specifications remain on the filter plate 18 and eventually slide down to the feeding structure 3 through the front discharge port 19 and the discharge chute 11. Fine debris and impurities fall through the mesh of the filter plate 18 into the bottom of the slag removal box 6, are collected by the guide slope 17, and then fall into the slag collection box 4 below through the discharge pipe 9. The clean slices conveyed by the feeding structure 3 then enter the color sorter 1 for precise color sorting, and finally obtain high-quality finished Chinese herbal medicine slices.
