TECHNICAL FIELD

[0001] The present application relates to a cutting machine for traditional Chinese medicine decoction pieces, in particular a composite conveying plate belt type pressure material shearing mechanism. BACKGROUND

[0002] As a gem of Chinese medicine, traditional Chinese medicine has played a huge role in the health of the Chinese people and the prosperity of the nation in its thousands of years of history. However, the traditional Chinese medicine industry itself has many aspects that need to be improved and improved.

[0003] The traditional dispensing method of traditional Chinese medicine is usually manual dispensing. When patients go to the pharmacy to pick up medicine, pharmacists directly take medicine from the opposite drawer of the traditional Chinese medicine cabinet, weigh and prepare the prescription for the patient to use. This manual dispensing method has the disadvantages of low efficiency, easy to make mistakes, time-consuming and laborious.

[0004] Some solutions have been proposed by traditional Chinese medicine field technicians in the automation of traditional Chinese medicine dispensing and dispensing, such as "full-automatic decoction piece intelligent traditional Chinese medicine dispensing machine" (CN104828445): the rack is provided with at least two rows of dispensing units, the dispensing unit is composed of a medicine storage box, a linear motion module, a turnover material hopper, a linear feeding hopper and the like, and is controlled by a mechanical automation program. It also has the characteristics of accurate measurement and fast dispensing speed.

[0005] The above technical solutions cannot automatically and intelligently complete all operations such as adding medicine, shearing and taking medicine. SUMMARY

[0006] The purpose of the present application is to provide a pressure material shearing mechanism, which is designed to automatically complete the operations of pressing traditional Chinese medicine decoction pieces, multiple shearing and taking medicine, etc., to match the "intelligent traditional Chinese medicine dispensing and dispensing system" invented by the present inventor.

[0007] The objective of this invention is achieved as follows: A pressing and shearing mechanism, used as a pressing and shearing mechanism on the discharge end of a lower discharge medicine-taking device, has the following structure: The discharge end of the lower discharge medicine-taking device is provided with lower stop teeth that are identical to and symmetrically arranged with the stop teeth; a lower blade holder is fixed to the front end of the lower stop teeth or integrated with them; left and right baffles are mounted and fixed on two clamping strips; two long optical shafts are respectively fixed to the front of the top of the left and right baffles; each long optical shaft is sequentially fitted with a linear bearing and a long spring; an upper top plate is fitted onto the upper part of the two long optical shafts; the upper ends of two short optical shafts, each fitted with a short spring, are fixed to the bottom surface of the upper top plate and located between the two long optical shafts; the lower ends of the two short optical shafts respectively extend into two blind holes on the top surface of a rectangular movable pressing block used for pressing medicinal materials; a gear motor is fixed to the outer wall of the hopper via a base and mounted on the gear... The driving gear and driven gear on the gear motor shaft mesh. A cam used to apply downward pressure to the upper plate is mounted on the driven gear shaft. A slide rail is mounted on the horizontal plate of the fixed base. The shearing motor is vertically mounted on the shearing motor base, which is fixed on the slider. The slider and the slide rail form a sliding fit. The shearing motor shaft is connected to the gear reducer. A short-bladed toothed blade is mounted on the output shaft of the gear reducer. The outer end face of the short-bladed toothed blade is in contact with and rotates with the outer end face of the lower cutter holder and the outer end face of the movable pressure block. The front side of the lower cutter holder is in contact with the short-bladed toothed blade to complete the cutting action. The crank is eccentrically mounted on the driving gear. The connecting rod is hinged to the crank and the pin on the shearing motor base, respectively. A limit switch is mounted on the horizontal plate of the fixed base, which is triggered by the slider to de-energize and stop the gear motor and shearing motor.

[0008] The structure of the bottom discharge and medicine dispensing device is as follows: the drive wheel is a cylindrical body with a flange on both end faces; the reduction motor consists of a motor and a reducer, the reduction motor is installed on the vertical section on the outer side of the left side plate, the D-shaped inner hole on the left end face of the drive wheel is fitted and fixed on the output shaft of the reduction motor, the shaft on the right end face of the drive wheel is mounted on the right side plate via a bearing, the right side plate is the same shape as the left side plate and is symmetrically arranged, a support wheel assembly consisting of multiple support wheels is installed and fixed between the left and right side plates, the top height of the multiple support wheels is the same as the top height of the drive wheel and they are all in a horizontal position, each support wheel structure is as follows: the shaft pin is installed on two needle roller shafts inside the cylinder, the right end of the shaft pin extending out of the cylinder has a disc for locking in the hole on the left side plate, the left end of the shaft pin extending out of the cylinder has a groove for locking with a snap ring; the rotating shaft located below the support wheel assembly is rotatably arranged between the rear of the left and right side plates;

[0009] The driven wheel structure is as follows: A flange is present on both end faces of the cylinder. The driven wheel shaft is mounted on two bearings inside the cylinder. The two outer ends of the driven wheel shaft extending from the cylinder have slots, and a retaining spring 209 is secured in these slots. The driven wheel assembly consists of a driven wheel mounted between two identical driven wheel left and right side plates. Two screws are screwed onto the protruding portions of the driven wheel shaft extending from the left and right side plates, respectively. Another support wheel is movably positioned between the left and right side plates of the driven wheel. The left and right side plates of the driven wheel are fixed to the rotating shaft. When the driven wheel assembly is not fixed and is in a free-hanging state, the stainless steel nail-type or baffle-type composite conveyor belt can be fitted onto the driving wheel and the driven wheel. When the driven wheel assembly is raised to a horizontal position, positioning screws are used to fix the left and right side plates of the driven wheel to the left and right side plates, respectively, thus putting the conveying equipment in a ready-to-work state.

[0010] A main intermediate beam is also fixed to the lower position of the support wheel assembly between the left and right sides of the driven wheel by fixing screws; a secondary intermediate beam is also fixed to the lower position of the other support wheel between the left and right sides of the driven wheel by screws.

[0011] The secondary intermediate beam is equipped with a scraper for scraping off the Chinese herbal medicine residue attached to the inner surface of the composite conveyor belt. The lower part of the left and right side plates is also fixed with a slag tray for collecting the slag scraped off by the scraper. The left and right side plates of the driven wheel are provided with slag discharge ports near the scraper position.

[0012] The left side plate is a bent plate with a horizontal leftward section, a vertical downward section, and a horizontal rightward section; the top horizontal sections of the left and right side plates are also respectively fixed with clips by screws. These clips are used to press onto the stainless steel nail-type or baffle-type conveyor belt to prevent the Chinese herbal medicine pieces from leaking out of the composite conveyor belt.

[0013] The left and right sides of the driven wheel are equipped with screws to install stop teeth at the feed end position. The lower part of the strip-shaped body has a row of toothed grooves for the corresponding steel nails on the stainless steel nail-type composite conveyor belt to pass through, and the concave arc surface of the lower front edge of the body is similar to the running trajectory of the top of the steel nail.

[0014] Each of the horizontal sections at the top of the left and right side plates has a quick-locking hole at the front, which is locked to the hopper using screws;

[0015] The stainless steel nail-type composite conveyor belt structure is as follows: the two wide sides of the steel belt are set at the same angle to the two parallel long sides, and the two wide sides are parallel to each other. Several rows of holes are evenly spaced along the long side of the steel belt, with small square holes and large square holes alternating in each row. The two wide sides of the steel belt are aligned and laser-welded together. The lower baffle structure is as follows: small square holes and large square holes are evenly spaced and alternating on the surface of the baffle strip with an arc-shaped cross-section. One or more grooves are opened at the bottom of the baffle strip. Each row of holes in the steel belt has one... Lower baffle: The large square heads on the lower baffle pass through the large square holes in the corresponding row of holes on the steel belt. The steel nail is composed of a small square head and a large square head integrated together. Multiple small square heads of the steel nails pass through the small square holes in the corresponding row of holes on the steel belt from top to bottom and are inserted into the small square holes on the lower baffle, and are laser welded together with the lower baffle. A PU silicone layer covers and fixes the bottom surface of the steel belt with the lower baffle to form a composite conveyor belt. The steel belt, lower baffle, and steel nails are all made of food-grade 304 stainless steel or food-grade 316 stainless steel.

[0016] The steel strip has an odd number of holes in each row, starting with and ending with a small square hole;

[0017] The large square head of the steel nail has the same shape as the large square head on the lower stop strip, both being cubic; the thickness of the steel strip is 0.1mm to 2mm, and the thickness of the PU silicone layer is 1mm to 10mm;

[0018] The short-bladed toothed blade structure is as follows: the disc body is integrally cut to form solid teeth that are adjacent to each other. The shape of each tooth is a pentahedron: in the front of the triangle, 9°≤∠A≤64°, 50°≤∠B≤99°, the back of the triangle is parallel and similar to the front of the triangle, and is larger than the front of the triangle. The angle between the top face of the quadrilateral and the back of the triangle forms the cutting edge. In the top face of the quadrilateral, the cutting edge line is parallel to the side corresponding to ∠B in the front of the triangle. The bottom face and the back face are the bottom face and the back face of the quadrilateral, respectively.

[0019] The back of the quadrilateral is perpendicular to the top surface of the quadrilateral, and the line of intersection between the back of the quadrilateral and the top surface of the quadrilateral is perpendicular to the cutting edge line in the top surface of the quadrilateral.

[0020] The cutting edge angle is 15° to 60°, the number of teeth is 16 to 24, and the tooth thickness, i.e., the thickness of the disc, is 0.5 mm to 5 mm.

[0021] The outer diameter of the disc body is 60mm, the number of teeth is 20, the thickness T of each tooth is 2mm, and the cutting edge degree is 45 degrees;

[0022] When the blade is cutting, the Chinese herbal medicine slices are placed between the lower blade holder, the upper pressure plate, and the side baffle. The blade teeth perform a translational and rotary cutting of the Chinese herbal medicine slices located below the blade edge from the root of the blade edge to the tip of the blade edge.

[0023] Compared with the prior art, the present invention has the following features and advantages.

[0024] 1. Adaptability: By using different hoppers, bottom discharge and medicine-taking devices, and counterweights of different weights, it can adapt to changes in the shape and density of medicinal materials and complete the extraction of different medicinal materials.

[0025] 2. Modular Design: The bottom discharge and dispensing device, metering, pushing, and flipping mechanism, as well as the pressing and shearing mechanism, all adopt a modular design, possessing relatively independent functions. If a certain device malfunctions, it can be replaced individually, thus achieving rapid replacement and maintenance. In particular, the locking strip of the bottom discharge and dispensing device cooperates with the slot on the hopper, and the design of using locking screws and locking holes to fix the two components in place enables rapid assembly, disassembly, and positioning of the bottom discharge and dispensing device.

[0026] 3. Precise Dispensing: The dispensing device uses a specially designed composite conveyor belt. Through careful design of the belt's width, the height and size of the steel teeth, and the action of a shearing mechanism and an elastic pressing mechanism, the difficult-to-separate medicinal materials are cut and smoothly dropped into the weighing pan, thus achieving accurate dispensing. The elastic pressing mechanism can be adjusted up and down according to the quantity of medicinal materials at the dispensing port, effectively compressing the materials.

[0027] 4. Fast dispensing speed: The entire herb-dispensing and shearing device may seem complex, but it works closely together, is fast and efficient, and can meet the purpose of quickly picking up medicinal herbs and slices.

[0028] 5. Eliminate material bridging: Under the action of its own weight and counterweight, the pressure plate mechanism compacts the loose medicinal materials, causing the medicinal materials to slide down in the hopper as they are removed, thus avoiding the phenomenon of empty bridges in the medicinal materials.

[0029] 6. Self-cleaning capability: The inside of the bottom-discharge medicine-collecting device is designed with a cleaning scraper, which can sweep the medicine residue and dust adhering to the inside of the composite tape through the residue inlet into the residue cover, and finally accumulate in the residue bag. Only periodic cleaning of the residue in the residue bag is required.

[0030] 7. Suitable for different types of medicinal materials: The composite conveyor belt type discharge shearing unit medicine cabinet is suitable for lightweight medicinal materials that are clumped together and have severe entanglement between individual pieces, such as loofah sponge and bamboo shavings.

The left and right side plates are fixed to the rotating shaft. When the driven wheel assembly is not fixed and is in a free-hanging state, the stainless steel nail-type or baffle-type composite conveyor belt 2029 can be fitted onto the driving wheel and the driven wheel. When the driven wheel assembly is raised to a horizontal position, positioning screws 2026 are used to fix the left and right side plates of the driven wheel to the left and right side plates respectively, thus putting the conveying equipment in a ready-to-work state.

A lower guide bar is provided: the large square heads on the lower guide bar pass through the large square holes in the corresponding row of holes on the steel belt. The steel nail is composed of a small square head and a large square head integrated together. Multiple small square heads of steel nails 503 pass through the small square holes in the corresponding row of holes on the steel belt from top to bottom and are inserted into the small square holes on the lower guide bar, and are laser welded together with the lower guide bar.

The steel belt, lower guide bar and steel nails are all made of food-grade 304 stainless steel or food-grade 316 stainless steel.

[0062] The steel strip has an odd number of holes in each row, starting with and ending with a small square hole;

[0063] The large square head of the steel nail has the same shape as the large square head on the lower stop strip, both being cubic; the thickness of the steel strip is 0.1mm to 2mm, and the thickness of the PU silicone layer is 1mm to 10mm;

The lower cutter holder 928a is fixed to the front end of the lower stop tooth or is integrated with the lower stop tooth. The front side of the lower cutter holder is in contact with the short-bladed toothed blade to complete the shearing action. Left and right baffles 924 are mounted and fixed on two clips. Two long optical shafts 920 are fixed to the front of the top of the left and right baffles respectively. Each long optical shaft is sequentially fitted with a linear bearing 920 and a long spring 923. The upper top plate 921 is fitted on the upper part of the two long optical shafts. Two short optical shafts 919 with short springs 918 are mounted on it. The upper ends of the two short optical shafts 919 are fixed to the bottom surface of the upper top plate and located between the two long optical shafts.

A limit switch 911 is mounted on the horizontal plate of the fixed base, which will de-energize and stop the gear motor and the shearing motor when touched by the slider 913.

[0065] The short-bladed toothed blade structure is as follows: the disc body is integrally cut to form solid teeth that are adjacent to each other. The shape of each tooth is a pentahedron: in the front of the triangle, 9°≤∠A≤64°, 50°≤∠B≤99°, the back of the triangle is parallel and similar to the front of the triangle, and is larger than the front of the triangle. The angle between the top face of the quadrilateral and the back of the triangle forms the cutting edge 6. In the top face of the quadrilateral, the cutting edge line is parallel to the side corresponding to ∠B in the front of the triangle. The bottom face and the back face are the bottom face and the back face of the quadrilateral, respectively.

[0066] The back of the quadrilateral is perpendicular to the top surface of the quadrilateral, and the line of intersection between the back of the quadrilateral and the top surface of the quadrilateral is perpendicular to the cutting edge line in the top surface of the quadrilateral.

[0067] The cutting edge has an angle of 15° to 60°, 16 to 24 teeth, and a tooth thickness (i.e., disc thickness) of 0.5 mm to 5 mm.

[0068] The outer diameter of the disc body is 60mm, the number of teeth is 20, the thickness T of each tooth is 2mm, and the cutting edge degree is 45 degrees;

[0069] When the blade is cutting, the Chinese herbal medicine slices 05 are placed between the lower blade holder 02, the upper pressure plate 03, and the side baffle 04. The blade teeth perform a translational and rotary cutting of the Chinese herbal medicine slices located below the blade edge from the root of the blade edge to the tip of the blade edge.

[0070] After the medication is added, collect the medication:

[0071] 1. After receiving the medicine picking instruction from the upper-level system, the control board driver program controls the lower discharge medicine picking device to start operating, and the control board driver program controls the shearing mechanism to start working.

[0072] 2. The geared motor in the bottom discharge and medicine taking device drives the composite conveyor belt to rotate, and the steel nails on the composite conveyor belt carry out the medicinal materials.

[0073] 3. As the medicinal herbs are carried out, the height of the herbs in the hopper decreases. The pressure plate mechanism with counterweights also descends under its own weight, maintaining continuous pressure on the herbs. At the same time, the pressure plate mechanism drives the sealing steel belt to rotate in the forward direction, ensuring the hopper is sealed.

[0074] 4. Single-stage herb-receiving and shearing process: After the composite conveyor belt rotates continuously for a specified time, the reduction motor in the herb-receiving device stops working under the control of the control board driver. At the same time, the control board driver controls the shearing reduction motor in the shearing mechanism to start rotating at high speed. Simultaneously, the control board driver controls the gear reduction motor in the shearing mechanism to start rotating. The driving gear drives the driven gear and the cam behind the driven gear to rotate together. During the rotation of the driven gear, the cam behind the driven gear presses the top plate of the movable pressure block downward. The top plate of the movable pressure block drives the movable pressure block to move downward. The movable pressure block presses the herb slices in the discharge port tightly. Under the action of the cam behind the driven wheel, the long spring, and the short spring, the herb slices are kept in a pressed state for a period of time during the rotation of the driven wheel. During the pressing process, while the driving gear drives the driven wheel to rotate, it drives the shearing reduction motor and the short-bladed toothed blade to move back and forth on the slide rail through the connecting rod. The short-bladed toothed blade cuts the herb slices, and the herb slices fall into the weighing pan of the metering and pushing flipping device. This completes one round of drug extraction and cutting.

[0075] 5. After repeated cutting and dispensing operations, once the required weight of medicine is reached, the metering and pushing device stops metering, the dispensing and dispensing device stops operating, and the shearing mechanism resets and stops working. The system then awaits medicine dispensing.

[0076] Dispensing medicine:

[0077] 1. After receiving the dispensing command from the upper system, the control board driver controls the motor in the rear door device to rotate outward, which in turn drives the connecting rod and sensor actuation plate to rotate outward. The connecting rod lifts the upper sealing plate of the rear door and drives the lower sealing plate of the rear door to open. When the sensor actuation plate rotates to a certain angle, it touches the rear door limit sensor, the motor stops rotating, and the rear door device remains open.

[0078] 2. While the control board driver controls the operation of the rear door device, it also controls the operation of the metering push and flipping device. The motor in the metering push and flipping device starts to rotate, pushing the weighing pan towards the rear door. After moving horizontally for a certain distance, the gears and racks on the weighing pan turn plate mesh, so that the weighing pan also has a flipping motion on the basis of horizontal movement, and begins to pour out the medicinal materials. Until the weighing pan flips to a certain angle and touches the limit switch, the motor stops rotating and the weighing pan stops flipping. At this time, the medicinal materials can be completely poured out.

[0079] 3. After the weighing pan maintains its tilt angle for a certain period of time, the control board driver program controls the motor in the metering push and flipping device to start rotating in the opposite direction. The weighing pan rotates back to a horizontal state, then moves horizontally back. After touching the limit switch, the motor stops rotating and the weighing pan resets.

[0080] 4. After the metering push-over device is reset, the control board driver controls the motor in the rear door device to rotate inward, which in turn drives the connecting rod and sensor actuation plate to rotate inward.

6. A control method for the pressing and shearing mechanism as described in claim 5, characterized in that, Includes the following steps: After the medication is administered, collect the medication:

1. After receiving the medicine picking instruction from the upper-level system, the control board driver program controls the metering and pushing device to start metering, the control board driver program controls the lower discharge and medicine picking device to start operating, and the control board driver program controls the shearing mechanism to start working.

2. The geared motor in the bottom discharge and medicine taking device drives the composite conveyor belt to rotate, and the steel nails on the composite conveyor belt carry out the medicinal materials and slices.

3. As the medicinal herbs are carried out, the height of the medicinal herbs in the hopper decreases, and the pressure plate mechanism with counterweights also decreases under its own weight, maintaining continuous pressure on the medicinal herbs; at the same time, the pressure plate mechanism drives the sealing steel belt to rotate in the forward direction to ensure the hopper is sealed.

4. Single-stage drug dispensing and shearing process: After the composite conveyor belt rotates continuously for a specified time, the reduction motor in the drug dispensing device stops working under the control of the control board driver program; simultaneously, the control board driver program controls the shearing reduction motor in the shearing mechanism to start high-speed rotation of the short-bladed toothed blade; at the same time, the control board driver program controls the gear reduction motor in the shearing mechanism to start, the driving gear drives the driven gear and the cam behind the driven gear to rotate together. During the rotation of the driven gear, the cam behind the driven gear presses the top plate of the movable pressure block downwards. The top plate of the movable pressing block moves it downwards, pressing the medicinal herbs in the outlet. Under the action of the cam, long spring, and short spring behind the driven wheel, the medicinal herbs remain pressed for a period of time during the rotation of the driven wheel. During the pressing process, the driving gear drives the driven wheel to rotate, which in turn drives the shearing reduction motor and the short-bladed toothed blade to move back and forth on the slide rail through the connecting rod. The short-bladed toothed blade cuts the medicinal herbs, which fall into the weighing pan of the metering and pushing flipping device. Thus, one herb removal and shearing operation is completed.

5. After repeated cutting and shearing operations, once the required weight of medicine is reached, the metering and pushing device stops metering, the discharge and medicine-taking device stops operating, and the shearing mechanism resets and stops working; then it waits for the medicine to be discharged. Dispensing medicine:

1. After receiving the dispensing command from the upper system, the control board driver controls the motor in the rear door device to rotate outward, which in turn drives the connecting rod and sensor actuation plate to rotate outward. The connecting rod lifts the upper sealing plate of the rear door and drives the lower sealing plate of the rear door to open. When the sensor actuation plate rotates to a certain angle, the sensor actuation plate touches the rear door limit sensor, the motor stops rotating, and the rear door device remains open.

2. While the control board driver controls the operation of the rear door device, it also controls the operation of the metering push and flipping device. The motor in the metering push and flipping device starts to rotate, pushing the weighing pan to move towards the rear door. After moving horizontally for a certain distance, the gear and rack on the weighing pan turn plate mesh, so that the weighing pan has a flipping motion on the basis of horizontal movement, and begins to pour out the medicinal materials. Until the weighing pan flips to a certain angle and touches the limit switch, the motor stops rotating and the weighing pan stops flipping. At this time, the medicinal materials can be completely poured out.

3. After the weighing pan maintains its tilt angle for a certain period of time, the control board driver program controls the motor in the metering push and flipping device to start rotating in the opposite direction. The weighing pan rotates back to a horizontal state, then moves horizontally back. After touching the limit switch, the motor stops rotating and the weighing pan resets.

4. When the metering push flipping device is reset, the control board driver controls the motor in the rear door device to rotate inward, and drives the connecting rod and sensor actuation disk to rotate inward. The connecting rod drives the upper and lower sealing plates of the rear door to rotate and close. When the sensor actuation disk rotates to a certain angle, the sensor actuation disk touches the rear door reset sensor, the motor stops rotating, and the rear door device is in the closed state.

5. Wait for the next dose of medication.
