Description

Technical Field

[0001] The present invention relates to the field of Chinese medicinal material processing, in particular to a Chinese medicinal material cutting device. Background Art

[0002] Traditional Chinese medicine cutting equipment is a mechanical device specifically used to cut traditional Chinese medicine into specific shapes and sizes. It aims to improve processing efficiency and ensure the quality of the medicine. This type of equipment uses blades, rollers, or hammers to achieve cutting. Some equipment is also equipped with an adjustment device to control the cutting thickness. The equipment is often made of stainless steel, meets hygiene standards, and has automation functions to reduce manual intervention. Some high-end equipment also integrates dust removal, cooling, or vacuum systems to protect the active ingredients of the medicine. Its application helps to standardize production, ensure the uniformity of the medicine during decoction, extraction, or preparation, and improve processing efficiency.

[0003] A Chinese patent with authorization announcement number CN216031029U discloses a Chinese medicinal material cutting device, including a support component, which includes a base and a limit plate. The limit plate is arranged on the base. There are two limit plates, and a limit space is formed between the two limit plates and the base. By arranging the two limit plates on the base and forming a limit space between the two limit plates and the base, the Chinese medicinal materials can be conveniently placed in the limit space, thereby facilitating the limitation. The clamping component is arranged on the base, and the clamping component can slide in the limit space, so that the positioned Chinese medicinal materials can be slowly pushed to the position of the cutting component, thereby realizing the cutting of the medicinal materials on the base by the cutting component. It is easy to use and can conveniently cut Chinese medicinal materials with a columnar structure, thereby improving work efficiency.

[0004] When the Chinese medicinal material cutting device of the above patent is used to cut medicinal materials, especially rhizomes, due to the shape of the strip-shaped rhizomes, the user needs to manually push the rhizomes so that the rhizomes are put into the cutting position in batches. During the entire process of cutting the rhizomes, the user needs to assist the device in operating for a long time. Summary of the Invention

[0005] The purpose of the present invention is to provide a Chinese medicinal material cutting device, in which batches of medicinal materials are uniformly placed on the upper end of the first conveyor belt. After being restricted by the second conveyor belt, a certain amount of medicinal materials can be sent to the upper end of the third conveyor belt in batches. After being sent to the upper end of the third conveyor belt, the medicinal materials can be continuously and quantitatively sent into the position where the tool moves back and forth longitudinally to cut the medicinal materials, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a Chinese medicinal material cutting device, comprising a cutter, a guide plate is provided at the lower end of the cutter, a second conveyor belt is provided at the rear end of the cutter, a first conveyor belt is provided at the lower end of the second conveyor belt, first transmission rollers rotating counterclockwise are provided on both sides of the first and second conveyor belts, a third conveyor belt is provided on one side of the first conveyor belt, a fourth conveyor belt is provided on one side of the first conveyor belt, second transmission rollers are provided on both sides of the fourth and third conveyor belts, and the transmission trajectories of the first and second conveyor belts are perpendicular to the transmission trajectories of the third and fourth conveyor belts.

[0007] Preferably, the second transmission rollers on both sides inside the fourth transmission belt rotate clockwise, and the second transmission rollers on both sides inside the third transmission belt rotate counterclockwise.

[0008] Preferably, the side of the fourth transmission belt corresponding to the second transmission roller is rotatably connected through a second connecting plate, a transmission plate is provided in the middle position of one side of the second connecting plate, an outer frame is provided on the outside of the transmission plate, and the outer frame is rotatably connected to the side of the third transmission belt corresponding to the second transmission roller.

[0009] Preferably, first connecting plates are provided at both front and rear ends of the first transmission rollers on both sides inside the second transmission belt.

[0010] Preferably, hydraulic rods are laterally provided at the lower ends of the two first connecting plates.

[0011] Preferably, a limiting frame is provided on the other side of the second conveyor belt.

[0012] Preferably, a threaded rod is longitudinally provided inside the outer frame, and the threaded rod passes through and extends to the upper and lower ends of the transmission plate, and the threaded rod is threadably matched with the transmission plate.

[0013] Preferably, the lower end of the hydraulic rod is provided with an electrically connected time controller.

[0014] Preferably, a limiting strip is provided on one side between the third conveyor belt and the fourth conveyor belt.

[0015] Preferably, a diffusion hole is provided inside the tool, and a pair of fans are provided on both sides of the tool. The fan on one side of the tool extracts external gas and transmits it toward the diffusion hole, and the fan on the other side of the tool extracts gas at the position of the diffusion hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The rhizome Chinese medicinal materials of the present invention are poured in batches onto the upper end outside the first conveyor belt, and the rhizome Chinese medicinal materials are placed in batches along the transmission direction of the third conveyor belt. After placement, the transmission of the first conveyor belt and the restriction of the rhizome Chinese medicinal materials by the second conveyor belt can enable a certain amount of rhizome Chinese medicinal materials to be transmitted from between the first conveyor belt and the second conveyor belt and fall on the upper end of the third conveyor belt. The rhizome Chinese medicinal materials fall on the upper end of the third conveyor belt one by one and are clamped one by one by the third conveyor belt and the fourth conveyor belt and are continuously and rapidly sent to the guide plate position. The transmission directions of the first conveyor belt and the second conveyor belt are matched with the fourth conveyor belt and the third conveyor belt with different transmission direction trajectories, so that the rhizome Chinese medicinal materials can be continuously and uniformly cut by the cutter. The user only needs to pour the rhizome Chinese medicinal materials in batches onto the upper end of the first conveyor belt, and the medicinal materials accumulated on the side of the second conveyor belt can be pushed laterally by the second conveyor belt. The lateral push makes the accumulated medicinal materials stay away from the third conveyor belt, thereby avoiding the accumulation of medicinal materials and avoiding the medicinal materials being squeezed and broken by the second conveyor belt and the first conveyor belt due to the accumulation of medicinal materials.

[0018] 2. According to the present invention, after the rhizomes of medicinal materials with different calibers are transmitted to the upper end of the third conveyor belt, the rotation of the threaded rod can drive and adjust the distance between the fourth conveyor belt and the third conveyor belt. The adaptation of the distance between the fourth conveyor belt and the third conveyor belt can stably clamp the rhizomes of Chinese medicinal materials, so that the rhizomes of Chinese medicinal materials can stably contact the cutting tool and stably cut the rhizomes of Chinese medicinal materials.

[0019] 3. When the tool of the present invention moves back and forth longitudinally, the diffusion hole reserved inside the tool will also move back and forth longitudinally. Fans are provided on both sides of the diffusion hole where the tool moves back and forth longitudinally. The fan on one side transmits gas toward the interior of the diffusion hole, while the fan on the other side extracts gas from the interior of the diffusion hole. When the tool cuts and generates high temperature, the stable gas flow inside the diffusion hole can quickly reduce the temperature of the tool. Actively reducing the temperature can prevent the loss of some heat-sensitive components of the drug due to high temperature. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to specific embodiments.

[0030] Example 1: Figure 1 As shown, a Chinese medicinal material cutting device of this embodiment includes a cutter 11. A guide plate 10 is provided at the lower end of the cutter 11. The medicinal material is transported toward the upper end of the guide plate 10 during transportation. After the medicinal material is transported to the upper end of the guide plate 10, the cutter 11 is driven to move back and forth longitudinally to complete the cutting of the medicinal material.

[0031] A transmission frame 15 is provided at the lower end of the outer portion of the tool 11. Telescopic rods 24 are provided on both sides of the transmission frame 15. When the tool 11 and the transmission frame 15 move back and forth longitudinally, the telescopic rods 24 will retract, and the telescopic rods 24 can provide support for the longitudinal reciprocating movement of the tool 11.

[0032] Among them, a first transmission bar 16 is provided at one end of the transmission frame 15, a second transmission bar 17 is provided at one end of the first transmission bar 16, a motor is fixedly provided at one end of the second transmission bar 17, and the second transmission bar 17, the first transmission bar 16 and the transmission frame 15 are rotatably connected in sequence. The output of the motor and the transmission of the second transmission bar 17 and the first transmission bar 16 can drive the transmission frame 15 to rotate, and the transmission frame 15 can be converted from rotational motion to longitudinal reciprocating motion by being restricted by the telescopic rods 24 on both sides;

[0033] Reference is made to a Chinese patent application with authorization publication number CN216031029U, which discloses a Chinese herbal medicine cutting device. The application describes a first transmission rod and a second transmission rod, and the first transmission rod and the second transmission rod are driven by a motor to cause a cutter to move back and forth longitudinally. The longitudinal reciprocating cutting method is similar to that of the present application, and therefore is not described in detail in the present application.

[0034] In order to avoid the high temperature of the cutter 11 caused by repeated use, to avoid the loss of some heat-sensitive components due to high temperature, and to avoid the gradual increase in the temperature of the cutter 11 and the reduction of the medicinal effect of the medicinal materials, such as Figure 4 As shown, the tool 11 is provided with diffusion holes 18 inside, and the diffusion holes 18 penetrate and extend to both sides of the tool 11. The reserved diffusion holes 18 can be used to remove heat, and at the same time, the reserved diffusion holes 18 can facilitate gas transmission;

[0035] A pair of fans 14 are longitudinally arranged on both sides of the cutter 11. When the fans 14 are activated, gas flow is actively generated. The fan 14 on one side of the cutter 11 extracts external gas and transmits it toward the diffusion hole 18. The fan 14 on the other side of the cutter 11 extracts gas at the location of the diffusion hole 18. By activating the fans 14 on both sides of the cutter 11, a stable air flow can be achieved, so that the air is stably transmitted toward the inside of the diffusion hole 18, actively cooling the cutter 11 during the cutting process.

[0036] Among them, such as Figure 2 and Figure 3 As shown, in order to further improve the stability of the air flow trajectory, an air inlet 12 is provided at one end of a fan 14 for extracting external air on one side of the tool 11, and an air outlet 13 is provided at one end of the other side of the tool 11 for extracting air from the diffused hole 18. The air can be extracted from the air inlet 12 by the fan 14, and the heat can be discharged from the air outlet 13.

[0037] In order to allow rhizome Chinese medicinal materials to be put into the device in batches without the user having to manually put in a certain amount of rhizome Chinese medicinal materials, a second conveyor belt 2 is provided at the rear end of the cutter 11, and a first conveyor belt 1 is provided at the lower end of the second conveyor belt 2. First transmission rollers 3 for straightening are provided on both sides of the first conveyor belt 1 and the second conveyor belt 2, and the first transmission rollers 3 can support the first conveyor belt 1 and the second conveyor belt 2 respectively;

[0038] The first transmission rollers 3 inside the first conveyor belt 1 and the second conveyor belt 2 both rotate counterclockwise. The first conveyor belt 1 can drive the medicinal materials toward the third conveyor belt 7 by the corresponding counterclockwise driving of the first transmission rollers 3. The second conveyor belt 2 can prevent a large number of stem-type Chinese medicinal materials from falling on the upper end of the third conveyor belt 7 by the corresponding counterclockwise driving of the first transmission rollers 3, so that a small amount of medicinal materials can be transmitted between the stretched second conveyor belt 2 and the first conveyor belt 1.

[0039] In order to prevent a large amount of medicinal materials from overflowing and falling outside the device due to the second conveyor belt 2, first connecting plates 4 are provided at the front and rear ends of the first transmission rollers 3 corresponding to both sides of the inside of the second conveyor belt 2. The first connecting plates 4 can drive the first transmission rollers 3 and the second conveyor belt 2 stretched by the first transmission rollers 3 to move laterally. The lower ends of the two first connecting plates 4 are both laterally provided with hydraulic rods 5. The contraction of the hydraulic rods 5 can drive the first transmission rollers 3 to move laterally. The laterally moving first transmission rollers 3 can laterally push the accumulated medicinal materials, so that the medicinal materials are pushed and away from the third conveyor belt 7, so as to avoid the medicinal materials being continuously squeezed on the side of the second conveyor belt 2 after being conveyed by the first conveyor belt 1, and to avoid the medicinal materials being squeezed and damaged, so that the equipment can withstand the unified input of large quantities of medicinal materials.

[0040] In order to further limit the shedding of medicinal materials, a limiting frame 25 is provided on the other side of the second conveyor belt 2. The upwardly extending limiting frame 25 can limit the overflowing medicinal materials.

[0041] One end of the first transmission roller 3 and the second transmission roller 9 are provided with a motor, which can drive the first transmission belt 1, the second transmission belt 2, the third transmission belt 7 and the fourth transmission belt 19 wound and stretched externally to rotate and transmit in corresponding directions;

[0042] In order to receive and subsequently cut the medicinal materials that fall from between the second conveyor belt 2 and the first conveyor belt 1, a third conveyor belt 7 is provided on one side of the first conveyor belt 1, and a fourth conveyor belt 19 is provided on one side of the first conveyor belt 1. The fourth conveyor belt 19 and both sides of the inner portion of the third conveyor belt 7 are respectively supported and straightened by the second transmission roller 9. After the medicinal materials fall on the upper end of the third conveyor belt 7, they are clamped by the fourth conveyor belt 19 and the third conveyor belt 7 to provide support for the stability of subsequent cutting;

[0043] Among them, such as Figure 6 As shown, the second transmission rollers 9 on both sides of the fourth transmission belt 19 rotate clockwise, and the second transmission rollers 9 on both sides of the third transmission belt 7 rotate counterclockwise. The rotation of the second transmission rollers 9 can push the medicinal materials and ensure that the medicinal materials are stably transported toward the guide plate 10.

[0044] In order to cope with the cutting and transportation of long stem Chinese medicinal materials, such as Figure 8 As shown, the transmission tracks of the first conveyor belt 1 and the second conveyor belt 2 are perpendicular to the transmission tracks of the third conveyor belt 7 and the fourth conveyor belt 19;

[0045] In order to adjust the spacing between the fourth conveyor belt 19 and the third conveyor belt 7, it can adapt to root and rhizome Chinese medicinal materials of different calibers. The fourth conveyor belt 19 is rotatably connected to the side corresponding to the second transmission roller 9 through the second connecting plate 20. A transmission piece 21 is provided in the middle position of one side of the second connecting plate 20. An outer frame 23 is provided on the outside of the transmission piece 21. The outer frame 23 is rotatably connected to the side of the third conveyor belt 7 corresponding to the second transmission roller 9. The adjustment of the longitudinal horizontal position of the transmission piece 21 in the outer frame 23 can adjust the spacing between the fourth conveyor belt 19 and the third conveyor belt 7.

[0046] The distance between the second conveyor belt 2 and the first conveyor belt 1 cannot be adjusted. The root materials falling between the second conveyor belt 2 and the first conveyor belt 1 will be flattened after falling on the upper end of the third conveyor belt 7 and can be clamped and conveyed by the fourth conveyor belt 19 and the third conveyor belt 7;

[0047] In order to facilitate the adjustment of the horizontal position of the transmission plate 21, as shown in FIG. Figure 7 As shown, a threaded rod 22 is longitudinally provided inside the outer frame 23. The threaded rod 22 passes through and extends to the upper and lower ends of the transmission plate 21. The outer portion of the threaded rod 22 is threadedly engaged with the penetration position of the transmission plate 21. By twisting the threaded rod 22 and the restriction of the transmission plate 21 by the outer frame 23, the transmission plate 21, the second connecting plate 20 and the fourth transmission belt 19 can be adjusted in the longitudinal horizontal position, and the spacing between the fourth transmission belt 19 and the third transmission belt 7 can be adjusted.

[0048] Example 2: A time controller 6 is provided at the lower end of the hydraulic rod 5, and the time controller 6 is electrically connected to the hydraulic rod 5. The time controller 6 can be driven regularly and give the hydraulic rod 5 a retraction signal. The retraction of the hydraulic rod 5 can push the medicinal materials accumulated on the side of the second conveyor belt 2;

[0049] In order to prevent the medicinal materials from falling from the upper end of the first conveyor belt 1 to the upper end of the third conveyor belt 7 and then falling off outside the device, Figure 5 As shown, a limiting strip 8 is provided on one side between the third conveyor belt 7 and the fourth conveyor belt 19. The limiting strip 8 can limit the material falling on the upper end of the third conveyor belt 7 and limit the gap on the side of the third conveyor belt 7 to prevent the medicinal materials from falling off;

[0050] Reference is made to the Chinese patent application CN215503228U, which discloses a compression hemostat with a pressure monitoring function. In this application, the second electric telescopic rod can be pulled up in a timed manner by a time controller. The driving method is the same as that of the present application. Therefore, in this application, the driving and connection method between the hydraulic rod 5 and the time controller 6 are not described in detail.

[0051] Working principle: When using the device and cutting rhizome Chinese medicinal materials, the user spreads the medicinal materials in batches horizontally on the upper end of the first conveyor belt 1. The first conveyor belt 1 is transported by the counterclockwise rotation of the first transmission rollers 3 on both sides inside, so that the first conveyor belt 1 pushes the medicinal materials toward the third conveyor belt 7. When contacting the third conveyor belt 7, the second conveyor belt 2 on the upper end of the first conveyor belt 1 is supported and transmitted by the first transmission rollers 3 on both sides inside and counterclockwise. The second conveyor belt 2 will limit the amount of medicinal materials falling from the upper end of the first conveyor belt 1 to the upper end of the third conveyor belt 7. When the medicinal materials accumulate and contact the second conveyor belt 2, the overflowing medicinal materials can be limited by the limiting frame 25. At the same time, the hydraulic rod 5 is started to extend and retract at a fixed time by the time controller 6. The hydraulic rod 5 can drive the first transmission rollers 3 on both sides of the second conveyor belt 2 to move horizontally through the first connecting plate 4, and push the medicinal materials that are about to overflow and are limited by the limiting frame 25 horizontally, so that the medicinal materials are away from the third conveyor belt 7. The medicinal materials are gradually transmitted to the upper end of the third conveyor belt 7. After the medicinal materials are transmitted to the upper end of the third conveyor belt 7, the second transmission roller 9 inside the third conveyor belt 7 rotates counterclockwise, and the second transmission roller 9 inside the fourth conveyor belt 19 rotates clockwise. The medicinal materials are transmitted toward the fourth conveyor belt 19 and the guide plate 10 along the third conveyor belt 7. After the medicinal materials contact the fourth conveyor belt 19, they can be clamped and fixed by the fourth conveyor belt 19 and the third conveyor belt 7 and subsequently transmitted until the medicinal materials are transmitted to the upper end of the guide plate 10. The motor at the rear end of the second transmission bar 17 drives the second transmission bar 17 and the first transmission bar 16 to rotate in sequence through the output shaft. The rotation of the first transmission bar 16 also drives the transmission frame 15 to rotate. After the transmission frame 15 is restricted by the telescopic rods 24 on both sides, the rotational motion is converted into longitudinal reciprocating motion. The longitudinal reciprocating motion of the transmission frame 15 can drive the cutter 11 to move back and forth to cut the medicinal materials at the upper end of the guide plate 10.
