Description

Technical Field

[0001] The present invention relates to the technical field of Chinese medicine decoction equipment, and in particular to a gear rack transmission device for realizing the movement of multiple decoction platforms of a Chinese medicine decoction machine to achieve automated decoction operation. Background Art

[0002] In the operation of the Chinese medicine decoction machine, the precise and stable movement of the decoction platform is the key to achieving efficient and automated decoction. However, most Chinese medicine decoction machines currently still use fixed stoves, which require manual handling or external thrust to move the decoction machine and the medicine pot. This traditional method has many problems: on the one hand, the decoction machine and the medicine pot are usually heavy, which makes manual pushing difficult, difficult to operate, and easily causes safety hazards; on the other hand, the traditional movement method makes it difficult to ensure that the decoction machine is accurately aligned with the heating area and the operating area, which easily leads to excessive friction between the roller and the track, which not only affects the service life of the equipment, but also reduces the efficiency of decoction.

[0003] In view of the difficulty in moving the medicine decoction machine and the medicine decoction platform, some improvements have been made in the prior art. For example, document CN118701706A discloses a medicine decoction pot push-pull device, which drives the medicine decoction pot to move between the loading platform and the medicine decoction station through a push-pull mechanism, simplifies the picking and placing steps, and realizes two-way picking and placing. Although this push-pull device improves the movement mode of the medicine decoction pot to a certain extent, it still has some limitations. A larger working space is required during the movement process, which may be subject to site restrictions in actual operation, and the device has high requirements on the weight and stability of the medicine decoction pot. The medicine decoction platform is prone to shaking and jamming during the movement, which not only affects the uniformity of Chinese medicine decoction, but also may cause errors in the decoction time, thereby affecting the efficacy.

[0004] In order to solve the problems existing in the above-mentioned prior art, the present invention proposes a novel platform moving mechanism for a Chinese medicine decoction machine. The mechanism adopts a gear rack transmission and a reduction motor drive, combined with a take-up mechanism and a limit device, to achieve automatic precise positioning and stable operation. Compared with the prior art, the present invention can not only effectively solve the problems existing in the prior art, but also further improve the automation level and intelligence of the decoction machine, reduce the difficulty of manual operation, and improve production efficiency and equipment safety. Summary of the invention

[0006] The technical solution adopted by the present invention to solve its technical problem is: A gear rack transmission device for moving the platform of a Chinese medicine decoction machine is characterized in that it includes a lift, a multi-pot decoction platform, a track support system, a gear rack transmission system, an automatic wire take-up device, a stopper, a rolling bearing, an oil storage tank and an integrated gas stove.

[0008] Further, with respect to claim 1, the track system includes stainless steel bull's eye bearing wheels, which are symmetrically arranged on both sides of the bottom of the decoction platform to reduce friction during movement.

[0009] Preferably, in the gear rack drive system, the gear is fixed to the gear shaft by a key connection, and the left side of the gear shaft is connected to a universal coupling for compensating the axis deviation between the output shaft of the DC reduction motor and the center of the gear. The universal coupling has a large angular compensation capability and can achieve reliable torque and motion transmission when the output shaft of the DC reduction motor and the center of the gear are not on the same axis.

[0010] Further, with respect to the second claim, the automatic wire take-up device can automatically wind or release the cable according to the movement of the decoction platform, ensuring that the cable is always in an appropriate tension state, avoiding the cable from dragging on the ground or excessive relaxation during movement. A turntable or guide device is designed inside, which can effectively prevent the cable from getting entangled during movement and reduce the risk of cable damage. The automatic wire take-up device has a compact structure design, occupies little space, and is easy to integrate into the transmission device.

[0011] Furthermore, the limiter is integrated into the multi-herb pot decoction platform, and is clearance-matched with the rack to limit the offset of the gear, ensuring that the gear and the multi-herb pot decoction platform move smoothly and horizontally on the second layer of the frame. The limiter is designed based on the "chopstick holding technology" to clamp the entire rack to ensure that the rack remains stable during movement. In the coordination design of the limiter and the rack, there are a total of 12 racks, distributed on both sides of the rack, to ensure the stability and reliability of the transmission system. The number and spacing of the limiters can be arranged according to different specific implementation cases to adapt to decoction machines of different sizes and configurations and meet diverse operational needs.

[0012] Preferably, the DC reduction motor is a 12V or 24V DC motor, which can realize forward and reverse rotation, and control the moving speed and direction of the decoction platform by speed regulation. Further, the decoction machine includes a multi-pot decoction platform, and the multi-pot decoction platform integrates multiple decoction pots, and the number is determined according to actual needs.

[0013] Preferably, the track system further comprises an oil storage tank, which is located below the rack and is used to store lubricating oil to reduce friction between the gear and the rack. In accordance with claim 3, the track system further comprises an oil storage tank, which is located below the rack and is used to store lubricating oil to reduce friction between the gear and the rack.

[0014] The gear rack transmission device for moving the platform of the Chinese medicine decoction machine of the present invention comprises a pair of multi-pot decoction platforms, the two decoction platforms have the same configuration, and are both integrated with multiple decoction pots. The number of decoction pots can be customized according to actual needs, thereby improving the decoction efficiency, meeting the production needs of different scales, allowing the decoction of multiple Chinese medicines at the same time, and improving the decoction efficiency. The same transmission system components are also provided, including a limiter, a DC reduction motor, a coupling, a universal coupling, a gear, a gear shaft, and a rolling bearing.

[0015] Furthermore, a limiter is integrated in the gap between the bottoms of the medicine decoction pots of the multi-pot medicine decoction platform. The limiter is used to limit the movement range of the medicine decoction platform to ensure that it stops accurately within the allowed range to prevent crossing the boundary. The limiter and the rack are clearance-matched to limit the deviation of the gear and ensure the stability and reliability of the transmission system.

[0016] Furthermore, the two multi-pot decoction platforms share an integrated gas stove, which is set on the second layer of the rack. By moving the decoction platform, different decoction pots can be placed on the gas stove in turn for heating. This not only improves production efficiency, but also reduces manpower operations and realizes automated decoction operations.

[0017] With respect to claim 4, the universal coupling of the present invention has a large angular compensation capability, and can realize reliable torque and motion transmission when the output shaft of the DC reduction motor and the center of the gear are not on the same axis. The left side of the gear shaft is connected to the universal coupling, which is used for mechanical transmission and power transmission between the gear and the rack and the DC reduction motor. The universal coupling utilizes the characteristics of its mechanism to enable the output shaft of the DC reduction motor and the center of the gear to rotate continuously and reliably transmit torque and motion even if they are not on the same axis and there is an axis angle. The processing difficulty is reduced, and the characteristics of the universal coupling structure with large angular compensation capability, compact structure and high transmission efficiency are fully utilized.

[0018] Furthermore, the universal coupling has a compact structure, occupies little space, and is easy to integrate into the overall structure of the transmission device. At the same time, its transmission efficiency is high, ensuring the high efficiency of power transmission, reducing energy loss, and improving the overall performance of the equipment.

[0019] Preferably, with respect to claim 5, the automatic wire take-up device is designed with a turntable or guide device inside, which can effectively prevent the cable from getting entangled during movement and reduce the risk of cable damage. Furthermore, the automatic wire take-up device has a compact structure design, occupies a small space, and is easy to integrate into the transmission device. Furthermore, the automatic wire take-up device ensures that the cable always maintains appropriate tension during the movement of the decoction platform through the turntable or guide device inside it, thereby smoothly transmitting electric energy to the DC reduction motor. The interruption or instability of electric energy transmission caused by loosening or winding of the cable during movement is avoided. The automatic wire take-up device works in conjunction with the DC reduction motor to ensure that the cable will not be damaged by external forces during movement, thereby ensuring that the DC reduction motor can run smoothly. Smooth power transmission and cable management are crucial to the stable operation of the DC reduction motor, which improves the overall efficiency and reliability of the equipment. Not only does it improve production efficiency, but it also reduces manual intervention, ensuring the long-term stable operation of the equipment.

[0020] Preferably, with respect to claim 6, the limiter is designed based on the "chopstick clamping technology" to clamp the entire rack and ensure that the rack remains stable during movement. The limiter is integrated into the remaining space at the bottom of the multi-herb pot decoction platform and directly fits with the rack. This ensures that the limiter can effectively limit the offset of the gear and prevent unnecessary displacement of the gear during operation, thereby maintaining the stability of the transmission system.

[0021] Furthermore, the limiter is designed with "chopstick clamping technology", which is similar to the principle of chopsticks clamping objects, and ensures that it remains stable during movement by clamping the entire rack. This not only improves the clamping force of the limiter, but also enhances its stability on the rack, ensuring that the decoction platform does not shake or jam during operation.

[0022] The number of the limiters in the present invention is 12 in total, which are evenly distributed on both sides of the rack. This distribution method can evenly withstand the force from the rack, ensuring the stability and reliability of the transmission system during operation. Through reasonable number and distribution, the limiters can effectively prevent the deformation and displacement of the rack, ensuring the precise positioning of the decoction platform. In particular, the number and spacing of the limiters can be arranged according to different specific implementation cases to adapt to decoction machines of different sizes and configurations.

[0023] Preferably, with respect to claim 7, the DC reduction motor is a 12V or 24V DC motor, which can realize forward and reverse rotation, and the moving speed and direction of the decoction platform can be controlled by speed regulation. The automatic wire take-up device ensures that the electric coupling transmits stable electric energy to the DC reduction motor, and the DC reduction motor outputs power and torque to the universal coupling, driving the gear shaft to rotate, and the gear is fixedly connected to the gear shaft and meshes with the rack. Under the meshing action of the gear and rack, the multi-herb pot decoction platform moves smoothly.

[0024] Furthermore, the forward and reverse functions and speed control of the DC reduction motor enable the decoction platform to move in both directions as needed, and the moving speed can be adjusted according to different decoction processes. The automatic cable take-up device ensures that the cable always maintains appropriate tension during movement, preventing the cable from being entangled or damaged, thereby ensuring stable power delivery to the DC reduction motor. The design of the universal coupling improves the reliability of the transmission system, and can achieve reliable torque and motion transmission even when the axes do not coincide.

[0025] With respect to claim 8, the medicine decoction platform of the present invention comprises a multi-medicine pot decoction platform, wherein the multi-medicine pot decoction platform integrates a plurality of medicine decoction pots, and the number is determined according to actual needs.

[0026] Preferably, the track system further comprises an oil storage tank, which is located below the rack and is used to store lubricating oil to reduce friction between the gear and the rack.

[0027] In response to claim 9, the present invention provides a gear rack transmission device for moving the platform of a traditional Chinese medicine decoction machine, wherein the oil storage tank is located below the rack and is used to store lubricating oil to reduce friction between the gear and the rack.

[0030] (2) The present invention effectively solves the problem of cables being easily entangled and damaged by force during movement by setting up an automatic cable take-up device, thereby improving the safety and reliability of equipment operation. The turntable or guide device inside the automatic cable take-up device can effectively prevent the cables from getting entangled during movement, reducing the risk of cable damage. The compact design of the automatic cable take-up device takes up little space and is easy to integrate into the transmission device, thereby improving the overall efficiency and reliability of the equipment.

[0031] (3) The limiter design of the present invention is based on the "chopstick holding technology", which can accurately limit the movement range of the decoction platform, ensure that it stops accurately within the allowable range, prevent it from crossing the boundary, and further improve the safety and reliability of the equipment.

DETAILED DESCRIPTION

[0044] The first embodiment of the present invention is further described below with reference to the accompanying drawings.

[0045] like Figure 1 and Figure 2 As shown, the present invention discloses a gear rack transmission device for moving a platform of a traditional Chinese medicine decoction machine, comprising a lifter (1), a multi-herb pot decoction platform (6), a track support system, a gear rack transmission system, an automatic wire take-up device (11), a stopper (5), a rolling bearing (17), an oil storage tank (8) and an integrated gas stove (10).

[0046] like Figure 1 and Figure 2 As shown, the present invention discloses a gear rack transmission device for moving a platform of a Chinese medicine decoction machine, wherein a lifter (1) is installed on the first layer of a frame (4) and is used to drive a multi-herb pot decoction platform (6) to be lifted and lowered between different layers of the frame (4). The lifter (1) drives the lead screw (3) to rotate, thereby driving the lead screw nut (2) to move vertically upward, thereby realizing the lifting function of the multi-herb pot decoction platform (6). The decoction platform can be switched between workstations at different heights as required, thereby improving the flexibility and operational convenience of the device.

[0047] The multi-pot decoction platform (6) integrates multiple decoction pots, and the number of decoction pots can be customized according to actual needs. Stainless steel bull's eye bearing wheels (9) are installed at the bottom of the decoction platform, and the bull's eye bearing wheels (9) are symmetrically arranged on both sides of the bottom of the platform to reduce friction during movement, ensure smooth movement of the platform, make the decoction platform smoother when moving horizontally, and reduce wear during operation.

[0048] Furthermore, an oil storage tank (8) is located below the rack (7) and is used to store lubricating oil. By adding lubricating oil between the rack (7) and the gear (15), the friction between the gear and the rack is effectively reduced, and the service life of the transmission parts is extended. The design of the oil storage tank (8) not only improves the efficiency of the transmission system, but also reduces the maintenance cost of the equipment.

[0049] Furthermore, the integrated gas stove (10) is arranged on the second layer of the frame (4) to provide a stable heat source for the medicine decoction pot. By moving the medicine decoction platform, different medicine decoction pots can be placed on the gas stove (10) in sequence for heating. This not only improves the utilization rate of the equipment, but also reduces the cost of repeated configuration, thereby achieving automation and efficiency of the medicine decoction process.

[0050] like Figure 3 As shown, the limiter (5) is integrated in the multi-herb pot decoction platform (6), and is clearance-matched with the rack (7) to limit the offset of the gear (15), thereby ensuring that the gear (15) and the multi-herb pot decoction platform (6) move smoothly and horizontally on the second layer of the frame (4). The limiter (5) is designed based on the "chopstick holding technology" and is used to clamp the entire rack (7) to ensure that the rack (7) remains stable during movement. In the matching design of the limiter (5) and the rack (7), there are a total of 12 racks distributed on both sides of the rack (7) to ensure the stability and reliability of the transmission system. The number and spacing of the limiters (5) can be arranged according to different specific implementation cases to adapt to decoction machines of different sizes and configurations and meet diverse operating requirements.

[0051] Further, combined with Figure 4 and 8For explanation, the track system includes a frame (4) and a rack (7) laid on the frame. The rack (7) meshes with the gear (15), and the horizontal movement of the decoction platform is achieved through the gear rack transmission. The frame (4) provides a support structure for the entire device to ensure the stable installation and operation of all components. The gear rack drive system includes a gear (15), a gear shaft (16), a universal coupling (14) and a DC reduction motor (12). The gear (15) is fixed to the gear shaft (16) by a key connection, and the left side of the gear shaft (16) is connected to the universal coupling (14), and the universal coupling (14) is connected to the output shaft of the DC reduction motor (12). The DC reduction motor (12) provides power, which is transmitted to the gear shaft (16) through the universal coupling (14), driving the gear (15) to rotate, thereby achieving the horizontal movement of the decoction platform. Figure 5 As shown, the design of the universal coupling (14) enables reliable torque and motion transmission to be achieved even if the motor output shaft and the gear shaft (16) are not on the same axis, thereby improving the reliability and flexibility of the system.

[0052] The rack (7) is designed in sections. In order to realize the movement of the medicine-decocting platform (6) in the vertical and horizontal directions, the rack (7) is designed as a sectioned structure. Specifically, the rack (7) is divided into a left rack and a right rack, and a certain gap is left between the two. It neither hinders the vertical up and down movement of the medicine-decocting platform nor hinders the horizontal movement of the medicine-decocting platform to the right. Specifically, when the medicine-decocting platform needs to be moved vertically from the first floor to the second floor, the elevator (1) is started to drive the lead screw (3) to rotate. The lead screw nut (2) moves vertically upward under the drive of the lead screw (3), thereby driving the multi-medicine pot medicine-decocting platform (6) to rise. During the process, the left rack and the medicine-decocting platform (6) move up and down together to ensure the smooth movement of the platform in the vertical direction.

[0053] When the medicine decoction platform (6) reaches the second layer of the frame (4), the left rack is fixed, and the medicine decoction platform (6) continues to move horizontally via the right rack. A certain gap is left between the right rack and the left rack to ensure that the left rack will not interfere with the right rack during the horizontal movement. This allows the medicine decoction platform (6) to move smoothly in the horizontal direction without being affected by the vertical movement.

[0054] like Figure 7 As shown, the automatic wire take-up device (11) is installed on the frame (4) and connected to the power supply cable of the DC reduction motor (12). The automatic wire take-up device (11) is designed with a turntable or a guide device inside, which can automatically wind or release the cable according to the movement of the decoction platform, ensuring that the cable is always in an appropriate tension state, preventing the cable from dragging on the ground or excessive relaxation during movement. The cable is effectively prevented from being entangled and damaged, and the safety and reliability of the equipment operation are improved.

[0055] like Figure 8 and 2 As shown, the rolling bearing (17) is fixed on the shell of the medicine decoction platform, and its inner ring is interference fit with the gear shaft (16), which is used to support the gear shaft (16) and ensure its smooth rotation. The design of the rolling bearing (17) reduces the friction of the gear shaft (16) and improves the stability and reliability of the transmission system.

[0056] The working principle of the first embodiment is as follows: when the decoction platform needs to be lifted from the first floor to the second floor, the lift (1) is started to drive the lead screw (3) to rotate. The lead screw nut (2) moves vertically upward under the drive of the lead screw (3), thereby driving the multi-herb pot decoction platform (6) to rise. The decoction platform moves smoothly on the track of the frame (4) through the bull's eye bearing wheel (9) and finally reaches the second floor.

[0057] Furthermore, on the second layer, the DC reduction motor (12) is started, and the power is transmitted to the gear shaft (16) through the universal coupling (14), driving the gear (15) to rotate. The gear (15) is meshed with the rack (7), and the horizontal movement of the medicine decoction platform is achieved through the gear rack transmission. The limiter (5) ensures that the gear (15) remains stable during the movement to prevent deviation. The automatic cable take-up device (11) automatically adjusts the length of the cable according to the movement of the medicine decoction platform to ensure stable power transmission.

[0058] Furthermore, after the decoction platform (6) is moved above the integrated gas stove (10), the decoction pot begins to heat. By moving the decoction platform, different decoction pots can be placed above the gas stove (10) in sequence for heating, thereby realizing an automated decoction process for multiple decoction pots. This not only improves production efficiency, but also reduces manpower operations.

[0059] The limiter (5) ensures that the medicine decoction platform stops accurately within a predetermined range to prevent it from crossing the boundary. The automatic cable take-up device (11) prevents the cable from being entangled and damaged, thereby improving the safety and reliability of the equipment operation.

[0060] On the basis of the first embodiment, the second embodiment further utilizes the design features of the gear rack transmission device for moving the platform of the Chinese medicine decoction machine of the present invention to adapt to the production needs of a larger scale and improve the stability and automation of the system. In the second embodiment, the scale of the multi-pot decoction platform (6) is further expanded, and more decoction pots are integrated to meet the needs of large-scale production. The number of decoction pots can be customized according to actual needs. This flexible configuration enables the decoction machine to handle multiple Chinese medicine decoction tasks at the same time according to the production scale and needs, effectively improving the production efficiency.

[0061] Furthermore, a double-layer decoction platform design is introduced, that is, a multi-pot decoction platform (6) is respectively provided on the second layer and the third layer of the frame (4). The two decoction platforms are automatically switched by the lift (1). When one decoction platform is performing decoction operation on the second layer, the other decoction platform can perform preparation work on the third layer, such as adding medicinal materials, cleaning Chinese medicine, and soaking. This allows the decoction platforms to operate in parallel, thereby improving the utilization rate and production efficiency of the equipment. Furthermore, in the decoction process, soaking is a key step. By soaking the medicine in advance on the decoction platform on the third layer, it can be ensured that the medicinal materials are fully soaked before decoction, which not only improves the decoction quality, but also reduces the time required for the entire decoction process.

[0062] Furthermore, an automatic control system is introduced. The system realizes precise control of the movement, lifting and decoction process of the decoction platform through sensors and controllers. In order to further improve the stability and life of the transmission system, the capacity of the oil storage tank (8) in the lubrication system of the second embodiment is increased, and an automatic lubrication device is provided. Lubricating oil is automatically replenished according to the use frequency and running time of the decoction platform to ensure that the rack (7) and the gear (15) are always kept in a good lubrication state.

[0063] In particular, the integrated gas stove (10) is optimized in the second embodiment to meet the needs of large-scale decoction. The power of the gas stove is increased, and it is equipped with efficient combustion equipment to ensure that the decoction pot can be heated quickly and evenly.

[0064] The working principle of the second embodiment is as follows: when the decoction platform needs to be lifted from the second floor to the third floor, the lift (1) is started to drive the lead screw (3) to rotate. The lead screw nut (2) moves vertically upward under the drive of the lead screw (3), thereby driving the multi-herb pot decoction platform (6) to rise. The decoction platform moves smoothly on the track of the frame (4) through the bull's eye bearing wheel (9) and finally reaches the third floor. On the third floor, the DC reduction motor (12) is started and transmits power to the gear shaft (16) through the universal coupling (14), driving the gear (15) to rotate. The gear (15) meshes with the rack (7) and realizes the horizontal movement of the decoction platform through the gear rack transmission. The limiter (5) ensures that the gear (15) remains stable during the movement to prevent deviation. The automatic wire take-up device (11) automatically adjusts the length of the cable according to the movement of the decoction platform to ensure stable power transmission.

[0065] After the decoction platform (6) is moved above the integrated gas stove (10), the decoction pot begins to heat. By moving the decoction platform, different decoction pots can be placed above the gas stove (10) in sequence for heating, thereby realizing an automated decoction process for multiple decoction pots. This not only improves production efficiency, but also reduces manpower operations.

[0066] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
