Description

Technical Field

[0001] This utility model belongs to the field of drying technology of traditional Chinese medicine decoction pieces, and in particular relates to a drying device for preparing traditional Chinese medicine decoction pieces. Background Technology

[0002] Drying in the preparation of Chinese medicinal herbs refers to the process of removing most of the moisture from wet medicinal herbs that have undergone cleaning, softening, cutting, or other processing steps, so that their moisture content meets the specified standards.

[0003] Currently, a commonly used drying equipment is the mesh belt dryer. However, when spreading Chinese medicinal herbs, some pieces are thick and some are thin, resulting in inconsistent drying quality and the problem of some pieces not being dried sufficiently.

[0004] To address the aforementioned issues, this application proposes a drying apparatus for preparing traditional Chinese medicine decoction pieces. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for preparing traditional Chinese medicine decoction pieces, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a drying device for preparing Chinese herbal medicine slices, including a machine body and a mesh conveyor belt inside it. The left end of the machine body is a feeding area, and a material box is provided on the top of the feeding area.

[0008] The front and rear of the feeding area are fixedly installed with transmission boxes. There are two sections of external transmission belt between adjacent transmission boxes. The left section is a horizontal section and the right section is an inclined section that slopes upward. The horizontal section of the external transmission belt is located at the lower end of the opening of the material box. A lever is provided above the inclined section of the external transmission belt near the top.

[0009] A guide plate is provided at the right end of the outer transmission belt, and the lower end extends to the adjacent mesh conveyor belt. A bottom plate extends to the left from the bottom of the mesh conveyor belt. A cleaning roller is installed inside the lower right end of the transmission box and is attached to the upper surface of the mesh conveyor belt. A suction fan is installed above the bottom plate, and a suction cylinder is provided on its left side. The opening of the suction cylinder is adjacent to the left end of the bottom plate.

[0010] Preferably, a fixing rod is fixed between adjacent transmission boxes, and a rotating sleeve is fixed to the upper end of the paddle and sleeved on the outside of the fixing rod.

[0011] Preferably, an inner transmission belt with the same path is fixed inside the outer transmission belt, and the inner transmission belt is divided into front and rear sections, forming a groove between them.

[0012] Preferably, a transfer roller is rotatably mounted inside the transmission box, located in the inner turning zone of the inner transmission belt, and an annular frame is rotatably mounted outside the transfer roller, located inside the empty groove.

[0013] Preferably, the annular frame has protruding support rods at both the front and rear, located between the outer drive belt and the inner drive belt.

[0014] Preferably, the upper end of the base plate is provided with a scraper blade, which is attached to the right side of the cleaning roller. The two ends of the scraper blade extend downwards and are fixedly connected to the base plate. The left end of the base plate has the same structure as the upper end of the scraper blade.

[0015] Preferably, the two ends of the suction cylinder are provided with communicating air ducts, which are connected to the suction fan.

[0016] This utility model has the following beneficial effects:

[0017] This invention utilizes an inclined structure in the discharge section of the external transmission belt. Under the influence of gravity, the accumulated Chinese medicinal herbs are agitated by a pry bar, ensuring that the herbs entering the outlet area are evenly spread out and can uniformly enter the mesh conveyor belt. This ensures that the herbs are heated evenly during the drying process, thereby improving their quality.

[0018] This invention uses a cleaning roller to adsorb residual impurities on the surface of a mesh conveyor belt, followed by two-stage cleaning via a base plate and scraper, and then suction discharge by a suction cylinder. This achieves real-time cleaning of the mesh conveyor belt to prevent poor contamination of the dried Chinese herbal medicine slices before and after drying, while also reducing the difficulty of subsequent equipment shutdown cleaning.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0037] Please see Figure 1-6As shown, this utility model is a drying device for preparing Chinese herbal medicine slices, including a machine body 11 and a mesh conveyor belt 12 inside it. The left end of the machine body 11 is a feeding area, and a material box 21 is provided on the top of the feeding area.

[0038] Transmission boxes 22 are fixedly installed at the front and rear of the feeding area. The transmission boxes 22 contain motors and drive mechanisms, which are mature existing technologies on the market. They are used to drive the two-section external transmission belts 221 between adjacent transmission boxes 22 to rotate. The left section of the external transmission belt 221 is a horizontal section, and the right section is an inclined section that slopes upward. The horizontal section of the external transmission belt 221 is located at the lower end of the opening of the material box 21. After the Chinese herbal medicine pieces fall, they are driven by the inclined section to form an upward climbing conveyor. Thus, the weight of the Chinese herbal medicine pieces piled up above can be used to make them fall automatically into the horizontal section for conveying again until they are spread on the bottom layer for feeding. A paddle 224 is set near the top of the inclined section of the external transmission belt 221 to paddle off some of the piled Chinese herbal medicine pieces that have not fallen.

[0039] A guide plate 222 is provided at the right end of the outer transmission belt 221, extending obliquely downward to the upper surface of the adjacent mesh conveyor belt 12. A bottom plate 2221 extends to the left from the bottom of the mesh conveyor belt 12. A cleaning roller 223 is installed inside the lower right end of the transmission box 22, driven by a rotary motor to rotate at a speed slightly greater than that of the mesh conveyor belt 12. The outer side of the cleaning roller 223 is made of soft rubber and is attached to the upper surface of the mesh conveyor belt 12. A suction fan 2222 is installed above the bottom plate 2221, and a suction cylinder 2223 is provided on its left side. The two are connected. The opening of the suction cylinder 2223 is adjacent to the left end of the bottom plate 2221 and is used to suck out the fallen impurities (the suction fan 2222 and its discharge method are mature existing technologies on the market and will not be described in detail here).

[0040] Furthermore, a fixed rod 2241 is fixed between adjacent transmission boxes 22, and a rotating sleeve 2242 is fixed at the upper end of the paddle 224 and sleeved on the outside of the fixed rod 2241. Under the action of gravity, the paddle 224 hangs down naturally, and its bottom forms a gap with the inclined section surface of the outer transmission belt 221, allowing the Chinese herbal medicine slices spread at the bottom layer to pass through.

[0041] Furthermore, an inner transmission belt 2211 with the same path is fixed inside the outer transmission belt 221. The front and rear ends of the two are an integral structure, and the inner transmission belt 2211 is divided into front and rear sections, with a slot 22111 formed between the two sections.

[0042] Furthermore, a transfer roller 2212 is rotatably mounted inside the transmission box 22, located in the internal turning area of ​​the inner transmission belt 2211, for supporting the two sections of the inner transmission belt 2211. An annular frame 22121 is rotatably mounted on the outside of the transfer roller 2212, located inside the empty groove 22111, and support rods 22122 protrude from both the front and rear of the annular frame 22121, located between the outer transmission belt 221 and the inner transmission belt 2211. By pulling the inner transmission belt 2211, a traction force is formed on the outer transmission belt 221, enabling it to maintain a stable working state in the horizontal and inclined sections.

[0043] Furthermore, the upper end of the base plate 2221 is provided with a scraper 2224, which is attached to the right side of the cleaning roller 223. It is used to scrape off the impurities adsorbed by the soft rubber on the outside of the cleaning roller 223, so that they can be sucked by the suction cylinder 2223. The two ends of the scraper 2224 extend downwards and are fixedly connected to the base plate 2221, while the middle section forms an opening to allow impurities to pass through. The left end of the base plate 2221 has the same structure as the upper end of the scraper 2224, and is used to scrape off the residual impurities on the surface of the mesh conveyor belt 12.

[0044] Furthermore, the suction cylinder 2223 has a communicating air duct 22231 at both ends, which is connected to the suction fan 2222 and used to transmit the air force of the suction fan 2222.

[0045] Understandably, this utility model can evenly spread Chinese herbal medicine slices during use, avoiding uneven heating caused by uneven thickness, thereby ensuring uniform drying quality of Chinese herbal medicine slices and reducing energy consumption of the equipment. At the same time, it can also clean the transmission mechanism in real time to avoid cross-contamination of Chinese herbal medicine slices dried at different times.

[0046] A specific application of the operation flow of this embodiment is as follows: During use, the Chinese herbal medicine slices first enter the left horizontal section of the outer conveyor belt 221. The support rod 22122 pulls the inner conveyor belt 2211, causing the right section of the outer conveyor belt 221 to turn upwards, thereby conveying the Chinese herbal medicine slices upwards. During this process, gravity causes the stacked Chinese herbal medicine slices to automatically fall downwards. Simultaneously, the rotating sleeve 2242 moves the stacked Chinese herbal medicine slices that have not yet fallen, causing them to fall automatically, thus allowing the bottom layer of Chinese herbal medicine slices to enter the top of the outer conveyor belt 221. The material is then guided by guide plate 222 and evenly falls onto mesh conveyor belt 12 to ensure uniform heating inside the dryer. During this period, the soft colloid on the outside of cleaning roller 223 adsorbs residual impurities on the surface of mesh conveyor belt 12, and scraper blade 2224 scrapes off the adsorbed impurities so that they fall into the opening of suction cylinder 2223. At the same time, bottom plate 2221 performs secondary cleaning on mesh conveyor belt 12, scraping off impurities on its surface so that they fall into the opening of suction cylinder 2223. Finally, the impurities are sucked out and discharged by suction fan 2222.
