Description

Technical Field

[0001] This utility model relates to the field of mugwort floss preparation technology, specifically a drying device for mugwort floss preparation. Background Technology

[0002] Mugwort floss is a soft, cotton-like substance made from mugwort leaves that have been repeatedly sun-dried, pounded, crushed, and sifted to remove impurities and dust. Its main functions include: promoting blood circulation, warming the meridians and stopping bleeding, dispelling cold and relieving pain, and maintaining health.

[0003] Chinese patent document with application number CN202420814931.4 in the related technology proposes a drying device for preparing moxa wool. It includes a box body, in which a heating mechanism is set inside. The heating mechanism includes a rotating shaft set in the middle of the bottom of the box body, a fan blade set at the top of the rotating shaft, a first rotating motor set at the bottom of the box body corresponding to the rotating shaft, multiple crossbars set in the middle of the box body, serpentine tubes set on the crossbars, a heating box connected to the serpentine tubes set at the front end of the box body, an end cap set at the top of the box body, multiple ventilation holes set at the top of the end cap, a conveying mechanism set on the box body, and a blower mechanism set at the top of the box body. It attempts to achieve double-sided drying by using a bottom heating mechanism and a top blower mechanism.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the conveyor belt surface is flat, the moxa floss easily clumps together, and there are still blind spots in the drying process on the contact surface. Especially for moxa floss raw materials with high moisture content, multiple re-drying processes are often required, affecting production efficiency. Therefore, a drying device for moxa floss preparation is proposed to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a drying device for preparing mugwort floss, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for preparing mugwort floss, comprising a box, a rotatable conveyor belt disposed inside the box, a drying mechanism disposed inside the box, a vibration mechanism disposed inside the box, and a dispersing mechanism disposed inside the box.

[0007] The vibration mechanism includes a drive motor and two rotating shafts housed inside the housing. A vibration frame is fixed to the outside of the rotating shafts. The vibration frame is located inside the conveyor belt, and the upper side of the vibration frame contacts the top of the inner side of the transmission belt. A sprocket is fixed on each of the two rotating shafts, and a chain meshes between the two sprockets. A drive motor for driving one of the rotating shafts to rotate is fixed on the housing.

[0008] Furthermore, the vibration mechanism includes an electric push rod and limiting plates disposed on both sides of the conveyor belt, and the housing is provided with an electric push rod for driving the limiting plates to move.

[0009] Furthermore, the dispersing mechanism includes a fixed shaft disposed inside the housing, and a material-turning frame is obliquely disposed at the lower end of the fixed shaft.

[0010] Furthermore, the lower end of the material turning frame is provided with rake teeth.

[0011] Furthermore, the drying mechanism includes heating boxes located on the upper and lower sides of the box body. Multiple heating wires are installed inside the heating boxes. Multiple air outlets are opened on the side of the heating boxes facing the conveyor belt. A fan is installed on the box body, and an air inlet pipe is connected between the air outlet of the fan and the side wall of the heating box.

[0012] Furthermore, the conveyor belt is provided with multiple circular holes.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This drying equipment for preparing mugwort floss significantly improves the uniformity and efficiency of mugwort floss drying by incorporating a vibration mechanism, a dispersing mechanism, and an optimized drying mechanism within the chamber. The vibration mechanism, driven by a motor, rotates the shaft and drives the chain and sprockets to cause the vibrating frame to vibrate at high frequency. This causes the mugwort floss to separate from the contact surface of the conveyor belt and loosen the accumulated material. Simultaneously, the electric push rod drives the limit plates on both sides of the conveyor belt to move, effectively preventing material from falling off the sides of the conveyor belt while controlling the material thickness, thus improving the stability of the drying process. The dispersing mechanism's inclined turning frame and rake teeth continuously move the material as the conveyor belt moves, achieving dynamic turning and dispersion, ensuring that the upper and lower surfaces and interior of the mugwort floss are fully exposed to hot air.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-3 The drying equipment for preparing moxa wool in this embodiment includes a box 1, a rotatable conveyor belt 2 inside the box 1, a drying mechanism 3 inside the box 1, a vibration mechanism 4 inside the box 1, and a dispersing mechanism 5 inside the box 1.

[0021] The vibration mechanism 4 includes a drive motor 405 and two rotating shafts 402 disposed inside the housing 1. A vibration frame 401 is fixed to the outside of the rotating shaft 402. The vibration frame 401 is located inside the conveyor belt 2, and the upper side of the vibration frame 401 contacts the top of the inner side of the conveyor belt 2. A sprocket 407 is fixed on each of the two rotating shafts 402, and a chain 406 meshes between the two sprockets 407. A drive motor 405 for driving one of the rotating shafts 402 to rotate is fixed on the housing 1.

[0022] The conveyor belt 2 is equipped with multiple round holes, and the hot air from the bottom heating box 305 is sprayed upward through the round holes, directly acting on the lower surface of the moxa wool.

[0023] After the drive motor 405 of the device is started, it drives the two rotating shafts 402 to rotate synchronously through the sprocket 407 and chain 406, causing the eccentrically set vibrating frame 401 to generate periodic centrifugal force, which drives the conveyor belt 2 to vibrate at high frequency. The vibration acts on the moxa wool material.

[0024] The vibration mechanism 4 includes an electric push rod 403 and a limiting plate 404 set on both sides of the conveyor belt 2. The inner surface of the limiting plate 404 is provided with anti-slip texture. The housing 1 is provided with an electric push rod 403 for driving the limiting plate 404 to move. According to the moisture content of the moxa wool and the drying requirements, the distance between the two limiting plates 404 is adjusted. When the anti-slip texture on the inner side of the limiting plate 404 comes into contact with the moxa wool, friction is generated. Combined with the vibration action, the material is prevented from slipping off both sides of the conveyor belt 2 due to excessive vibration amplitude, thereby improving the stability of equipment operation.

[0025] Meanwhile, the dispersing mechanism 5 includes a fixed shaft 502 set inside the housing 1. A tilting frame 501 is obliquely set at the lower end of the fixed shaft 502. When the conveyor belt 2 drives the moxa wool to move forward, the oblique tilting frame 501 cuts into the material layer and realizes dynamic dispersing by using the principle of relative motion. When the moxa wool comes into contact with the inclined surface of the tilting frame 501, it is blocked and moves upward and is picked up. After the bottom material moves with the conveyor belt 2 and passes under the tilting frame 501, it falls naturally onto the conveyor belt 2 due to gravity, realizing the exchange of the upper and lower surfaces.

[0026] In addition, the lower end of the turning frame 501 is equipped with rake teeth, which are evenly distributed on the bottom surface of the turning frame 501. The rake teeth at the lower end of the turning frame 501 can penetrate into the interior of the moxa wool clumps, break up the clumps and comb the fibers through mechanical force, so that the material is dispersed into uniform granules, while increasing the surface area and porosity of the material, significantly improving the hot air penetration effect and drying uniformity.

[0027] Please see Figure 1-2 In this embodiment, the drying mechanism 3 includes heating chambers 305 disposed on the upper and lower sides of the chamber 1. Multiple heating wires 302 are disposed inside the heating chambers 305. Multiple air outlets 304 are opened on the side of the heating chambers 305 facing the conveyor belt 2. A fan 303 is disposed on the chamber 1, and an air inlet pipe 301 connects the air outlet of the fan 303 to the side wall of the heating chamber 305.

[0028] The device's fan 303 compresses ambient air into the heating box 305, which is then heated by the heating wire 302 and blown onto the conveyor belt 2 through the air outlet 304. The air outlets 304 of the lower heating box 305 are arranged in an alternating pattern to form a vertically intersecting hot air path, ensuring that the upper and lower surfaces of the moxa wool are heated simultaneously.

[0029] The working principle of the above embodiments is as follows:

[0030] The moxa wool material is evenly spread on the conveyor belt 2. The drive motor 405 is started, and the material moves with the conveyor belt 2. At the same time, the drive motor 405 drives the rotating shaft 402 and the vibrating frame 401 through the sprocket 407 and chain 406 to generate high-frequency micro-vibration, causing the moxa wool to separate from the contact surface of the conveyor belt 2 and loosen into a uniform thin layer. When the material moves to the bottom of the spreading mechanism 5, the inclined turning frame 501 fixed to the top of the box 1 cuts into the material layer, using relative motion to lift the moxa wool upward and naturally flip it. If the turning frame 501 has rake teeth at the bottom, it further breaks up the clumps and combs the fibers. At the same time, the blower 303 pressurizes air into the upper and lower heating boxes 305, which is heated by the heating wire 302 and sprayed out through the air outlet 304. The hot air from the top blows the upper surface of the material, and the hot air from the bottom penetrates to the lower surface through the round hole of the conveyor belt 2. Combined with the turbulence effect formed by vibration and spreading, the heat exchange efficiency is improved. The anti-slip texture on the inner side of the limiting plate 404 on both sides of the conveyor belt 2, in conjunction with the vibration, prevents the material from falling.
