Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece screening technology, and in particular to a traditional Chinese medicine decoction piece screening structure that is compatible with a variety of medicinal materials. Background Technology

[0002] After processing, Chinese medicinal herbs (TCM) slices need to be screened and graded to ensure uniform specifications, facilitating subsequent formulation and efficacy. Different medicinal materials exhibit significant differences in physical properties. For example, leaf and flower slices are thin and fragile, while root and stem slices are harder. Rehmannia glutinosa and Polygonatum sibiricum, after processing, become viscous and prone to clumping. Traditional screening methods rely on vibrating screening equipment with fixed parameters, achieving grading through differences in screen aperture. In actual production, this requires frequent equipment changes or parameter adjustments to suit the characteristics of different herbs. With the large-scale development of the TCM industry, the demand for versatility and adaptability of screening equipment is increasing. There is an urgent need for a screening structure that can flexibly handle the characteristics of various medicinal materials, reducing operational complexity and improving screening efficiency and quality.

[0003] Current Chinese herbal medicine (TCM) decoction piece screening equipment uses fixed vibration intensity. For fragile pieces, excessive intensity can lead to breakage, affecting efficacy and appearance. Conversely, insufficient vibration intensity for sticky pieces makes it difficult to break up the adhesion, causing sieve blockage and requiring frequent shutdowns for cleaning, thus reducing production efficiency. Furthermore, most equipment suffers from poor adaptability; changing the type of medicinal material requires disassembly and adjustment of core components, a complex and time-consuming process that fails to meet the needs of multi-variety, small-batch production. Additionally, the fixed vibration mode cannot accommodate the screening requirements of different medicinal materials, resulting in inconsistent screening accuracy and affecting the stability of decoction piece grading quality.

[0004] Therefore, a new screening structure for Chinese herbal medicine slices that is compatible with a variety of medicinal materials is proposed to solve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved The purpose of this invention is to provide a screening structure for Chinese herbal medicine slices that is adaptable to various medicinal materials. By setting up detection components, it solves the problem that current Chinese herbal medicine slice screening equipment has a fixed vibration intensity. For fragile slices, excessive vibration intensity can easily lead to breakage, affecting efficacy and appearance. Conversely, for sticky slices, insufficient vibration intensity makes it difficult to break up the adhesion, easily causing sieve blockage and requiring frequent shutdowns for cleaning, reducing production efficiency. In addition, most equipment has poor adaptability; changing the type of medicinal material requires disassembly and adjustment of core components, which is complex and time-consuming, making it difficult to meet the production needs of multiple varieties and small batches. At the same time, the fixed vibration mode cannot take into account the screening requirements of different medicinal materials, resulting in inconsistent screening accuracy and affecting the stability of the slice grading quality.

[0006] 2.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-5As shown, this embodiment is a screening structure for Chinese herbal medicine slices adapted to various medicinal materials, including a base plate 110. Two first supports 111 are installed on the base plate 110. A second mounting plate 122 is installed on one of the first supports 111. A second bearing 123 is installed on the second mounting plate 122. A rotating shaft 124 is installed at the other end of the second bearing 123. A protrusion is installed on the rotating shaft 124. A second support 130 is installed at each of the four corners of the upper end of the base plate 110. A support plate 131 is installed at the top of any two corresponding second supports 130. Three springs 242 are installed at the bottom of any one of the support plates 131. A material box 210 is installed at the bottom of the two sets of springs 242. A filter frame 230 is installed inside the material box 210. The material box 210 is installed at an angle. A first mounting plate 120 is installed on the base plate 110, and a first bearing 121 is installed on the first mounting plate 120. The rotating shaft 124 passes through the first bearing 121. This design can effectively reduce the wear generated when the rotating shaft 124 rotates and increase the service life of the device. A handle 129 is installed on one end of the rotating shaft 124 near the first mounting plate 120. The handle 129 has multiple resistance grooves. This design can increase the friction between the handle 129 and the operator's hand, making it more labor-saving. Multiple first threaded holes 126 are opened on the rotating shaft 124, and first and second threaded holes 127 are opened on the protrusion. A first bolt 128 is installed in the second threaded hole 127, and any one of the first threaded holes 126 of the first bolt 128 is engaged. This design can stably fix the cam 125 on the rotating shaft 124. A collection box 220 is installed in the material box 210. The collection box 220 is located below the filter frame 230. The collection box 220 in this design can collect the filtered medicine.

[0023] Working principle: During operation, when screening is required, the medicine is poured directly into the material bin 210, where it will be placed on the filter screen 231. Then, the handle 129 is grasped to rotate the rotating shaft 124. The rotation of the shaft 124 causes the cam 125 to rotate, which in turn causes the material bin 210 to vibrate. This vibration of the material bin 210 allows for rapid screening of the medicine inside. When the type of medicine changes, the vibration intensity is adjusted according to the required type. Adjust the position of cam 125 on the rotating shaft 124. If you need to increase the vibration intensity, simply move cam 125 on the rotating shaft 124 toward the handle 129. Then, install the bolt into the second threaded hole 127 on cam 125 and the corresponding first threaded hole 126 on the rotating shaft 124. Since the material box 210 is installed at an angle, cam 125 and material box 210 become closer. At this time, the vibration amplitude will increase. Conversely, when you need to decrease the vibration intensity, simply move cam 125 away from the handle 129.

[0024] The inner sidewall of the material box 210 has four sliding grooves 211 at both ends. The filter frame 230 has four sliders 232 installed at both ends. Each slider 232 is installed in the corresponding sliding groove 211. Each sliding groove 211 has a slot 212 at the bottom. Each slider 232 has a locking block 233 at the bottom. Each locking block 233 engages with the corresponding slot 212. This design can greatly increase the speed of disassembly and assembly of the filter frame 230. Three mounting tubes 240 are installed at both ends of the material box 210. Each mounting tube 240 is equipped with a mounting ring 241, and each mounting ring 241 is connected to a corresponding spring 242. Each mounting tube 240 has a third threaded hole 243, and each third threaded hole 243 has a second bolt 244 installed in it. Each second bolt 244 has a baffle 245 installed at the end away from the corresponding second mounting tube 240. The length of each baffle 245 is greater than the outer diameter of the mounting ring 241. This design facilitates the disassembly and assembly of the material box 210, and the baffle 245 can effectively prevent the mounting ring 241 from falling off the mounting tube 240.

[0025] Working principle: When the filter screen 231 is stuck, directly grasp the filter frame 230 and lift it upward. When the filter frame 230 moves upward, the locking block 233 at the bottom of the slider 232 will disengage from the slot 212 on the material box 210. After cleaning, simply put the filter frame 230 into the material box 210 and engage the corresponding locking block at the bottom of the slider 232 into the slot 212. When the material box 210 needs to be cleaned, simply unscrew the corresponding second bolt 244 from the third threaded hole 243, and then remove each mounting ring 241 from the mounting tube 240. At this time, the material box 210 can be removed for cleaning. After cleaning, reassemble in reverse order.
