Description

Technical Field

[0001] The invention belongs to the technical field of medicinal material processing, and in particular relates to drying equipment and a method for processing Chinese herbal medicine slices. Background Art

[0002] Drying is a crucial step in the processing of Chinese herbal medicine slices, directly impacting their quality and efficacy. Currently, the drying equipment commonly used on the market mostly places the slices to be dried directly inside the equipment, where they are heated and dried at a fixed position. However, this approach has significant limitations: because the slices remain in a fixed position relative to the hot air during the drying process, different parts of the slices are heated unevenly, leading to inconsistent drying progress. Specifically, some slices may not be dried thoroughly, while others may not be dried enough. This uneven drying effect not only affects the quality of the Chinese herbal medicine slices but may also adversely affect their efficacy.

[0003] Based on this, the present invention designs a drying device and method for processing Chinese herbal medicine slices to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the above-mentioned background technology and to propose a drying device and method for processing Chinese herbal medicine slices.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A drying device and method for processing Chinese herbal medicine slices, comprising a bottom bracket, a drying box fixedly connected to the outside of the bottom bracket, a conveyor belt rotatably connected to the inside of the bottom bracket, two rotating support wheels slidably connected to the inside of the conveyor belt, a rotating shaft passing through the rotating support wheel, the rotating shaft rotatably connected to the bottom bracket, a rotating vibration mechanism slidably connected to the inside of the conveyor belt, the rotating vibration mechanism fixedly connected to the bottom bracket, three rubber baffles fixedly connected to the inner wall of the drying box, and a hot air blower provided on the drying box.

[0007] The front of the drying box is hinged with two take-in and put-out doors, the front of the drying box is provided with a control panel, the back of the bottom bracket is provided with a driving mechanism, and the output shaft of the driving mechanism is connected to the conveyor belt.

[0008] The inner wall of the drying box is provided with four support bearings, and the positions of the two support bearings on the left and the two support bearings on the right correspond to the positions of the rotating support wheels on the left and right sides respectively. A connecting shaft is rotatably connected in the two support bearings on the left, and a roller is provided outside the connecting shaft.

[0009] Two supporting plates are fixedly connected inside the bottom bracket, a material hole is penetrated outside the conveyor belt, the positions of the three rubber baffles correspond to the positions of the rotating vibration mechanism, and the two rotating support wheels are located on the left and right sides of the rotating vibration mechanism.

[0010] The rotary vibration mechanism includes a driving assembly, the back of the driving assembly is fixedly connected to a fixed rod, the fixed rod is fixedly connected to the bottom bracket, the output shaft of the driving assembly is fixedly connected to an extrusion wheel, the extrusion wheel is slidably connected to a contact rod, and the bottom end of the contact rod is fixedly connected to a movable plate.

[0011] The movable plate is fixedly connected with a vertical rod, the top end of the vertical rod is fixedly connected with a movable guide frame, two top wheels are rotatably connected in the movable guide frame, the top wheels are slidably connected in the conveyor belt, two telescopic rods are fixedly connected under the movable guide frame, and the bottom end of the telescopic rod is fixedly connected with an extension plate arranged in the bottom bracket.

[0012] The outer sleeve of the telescopic rod is provided with an elastic component, the two ends of the elastic component are respectively fixedly connected to the movable guide frame and the extension plate, the left and right parts of the upper surface of the movable guide frame are both inclined, and the sides where the two supporting plates are close to each other are both located below the movable guide frame.

[0013] A method for using the drying device, comprising the following steps:

[0014] The pieces to be dried are placed on the conveyor belt. During the rotation of the conveyor belt, the pieces are driven to move to the right into the drying box. The hot air blower works to blow and dry the pieces on the conveyor belt. At the same time, the driving component is controlled to work. The driving component drives the extrusion wheel to rotate. The convex position of the extrusion wheel squeezes the contact rod downward. When a momentary separation state occurs between the contact rod and the extrusion wheel, the elastic component controls the moving plate and the top wheel to instantly reset upward. The top wheel pushes the conveyor belt between the two rotating support wheels on the upper side upward to push up the pieces on the upper side of this part of the conveyor belt, so that the pieces can be instantly vibrated and the debris on the surface can be removed. The loose corners fall off due to vibration, and the fallen residues pass through the conveyor belt and fall on the carrying plate. Since this part of the conveyor belt is shaken, the residue is not easy to block the conveyor belt, and the upward-bouncing medicinal slices contact the rubber baffle, and the roller blocks the squeezed upward conveyor belt to prevent the conveyor belt from tilting over a large area. The medicinal slices moving to the right are blocked by the rubber baffle, and the medicinal slices are blocked and flipped. The flipping of the medicinal slices allows them to fully and evenly contact the hot air. After falling, the flipped medicinal slices can contact the conveyor belt at different positions, achieving better vibration cleaning effect and more ideal drying effect and efficiency.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In the present invention, an extrusion wheel, a contact rod, an elastic component and a top wheel are used. When the raised position of the extrusion wheel acts on the contact rod, the contact rod is pressed and moved downward; then, at the moment when the contact rod is separated from the extrusion wheel, the elastic component responds quickly, pushing the movable plate and the top wheel to reset upward instantly. This action causes the top wheel to generate an upward pushing force on the conveyor belt between the two upper rotating support wheels, thereby pushing up the medicinal slices on the upper side of this part of the conveyor belt. The lifted medicinal slices then contact the rubber baffle above and are flipped under the action of the baffle. This flipping action ensures that the medicinal slices can fully and evenly contact the hot air, thereby significantly improving the drying efficiency and effect of the medicinal slices.

[0017] 2. In the present invention, rubber baffles, conveyor belts and top wheels are used. When the medicinal slices on the upper side of the conveyor belt are lifted up by the top wheel, the medicinal slices are instantly vibrated. This vibration effect allows the debris and loose corners on the surface of the medicinal slices to fall off effectively, and the fallen residues pass smoothly through the holes in the conveyor belt and fall on the supporting plate below. In addition, since the conveyor belt vibrates under the action of the top wheel, the problem of residue blocking the conveyor belt is effectively avoided, ensuring the continuous and stable operation of the equipment. The turned medicinal slices can contact the conveyor belt at different positions during the falling process, further enhancing the vibration cleaning effect.

[0018] 3. In the present invention, rotating support wheels and rollers are used. When the conveyor belt moves upward under the action of squeezing, the rollers block it in time, effectively avoiding the conveyor belt from tilting over a large area. At the same time, the tacit cooperation between the rotating support wheels and the rollers ensures the overall stability of the upper horizontal part of the conveyor belt, and prevents the occurrence of overall tilting. This innovative design enables the medicinal slices to be transported smoothly and orderly during the drying process, avoiding problems such as slipping, accumulation or uneven drying of the medicinal slices caused by the tilt of the conveyor belt.
