Description

Technical Field

[0001] This invention relates to the field of medicine cutting machine technology, and in particular to a linear reciprocating medicine cutting machine with a blade support assembly. Background Technology

[0002] Linear reciprocating herb cutter is a commonly used cutting equipment in the field of Chinese herbal medicine processing. It mainly relies on the reciprocating lifting of the cutter in conjunction with the continuous feeding of the conveyor belt to realize the fixed-length cutting of various root and herb medicinal materials. It has the characteristics of fast processing speed and wide applicability, and is widely used in the large-scale production process of Chinese herbal medicine slices.

[0003] In traditional technology, the cutting is usually carried out in the middle of the conveyor belt. After cutting, the medicinal materials can be conveyed to the next station until they fall from the end of the conveyor belt into the collection box. However, the cutting is completed by directly supporting the medicinal materials with the conveyor belt. When the cutter falls to cut, the blade will act on the surface of the conveyor belt. Long-term repeated cutting will easily produce a lot of scratches of varying depths on the surface of the conveyor belt, shorten the service life of the conveyor belt, and reduce processing efficiency.

[0004] Therefore, it is necessary to propose a linear reciprocating medicine cutting machine with a blade support assembly to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a linear reciprocating medicine cutting machine with a blade support assembly to solve the problem of generating a large number of scratches of varying depths when the medicine is directly supported by a conveyor belt for cutting.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a linear reciprocating medicine cutting machine with a knife support assembly, comprising a conveyor belt and a stand on the top of the worktable, a cutter slidably disposed on the stand, the stand being located at the end of the conveyor belt, a support mechanism disposed on the stand, the support mechanism comprising a support plate, the support plate being rotatably disposed on the stand, and a torsion spring being installed at the rotatable connection. The cutter is movably mounted with a telescopic synchronization component that cooperates with the support plate; Before slitting, the cutter drives the synchronizing component to move downwards and touch the support plate to flip it into a horizontal position, forming a conveying plane with the upper conveying surface of the conveyor belt, so that the medicinal materials can slide from the conveyor belt to the surface of the support plate. During the cutting process, the cutter relies on the extension and retraction of the synchronous component to reserve the space for the movement of the cutter, and moves up and down to cut the medicinal materials fed onto the surface of the support plate. After slicing, the cutter moves upward with the synchronizing element to separate from the support plate. The support plate returns to its tilted position to form an airflow that blows away the adhering tablets on the cutter and removes the temporarily stored tablets.

[0007] Preferably, the upright frame is provided with side strips, and crossbars distributed along the width direction of the conveyor belt are fixed on the side strips, and the middle section of the support plate rotates on the crossbars; The synchronization component includes a mounting frame, an elastic telescopic rod, and a vertical rod. The mounting frame, the elastic telescopic rod, and the vertical rod are fixed sequentially from top to bottom. The mounting frame is detachably installed on the top of the cutter side wall. The bottom end of the vertical rod abuts against the support plate, and the abutment position is located between the horizontal rod and the conveyor belt.

[0008] Preferably, the support plate has a movable chamber at the end near the conveyor belt; The movable chamber is equipped with a telescopic assembly that cooperates with the cutter. The telescopic assembly includes a stabilizing plate, an elastic plate, and a spring. The stabilizing plate is slidably disposed in the movable chamber, the elastic plate is fixed on the side of the stabilizing plate near the conveyor belt, and the spring is installed between the stabilizing plate and the inner wall of the movable chamber. The elastic plate is made of high-toughness, wear-resistant polyurethane material.

[0009] Preferably, the top of the edge strip is fixed with an ear plate, and a guide slide is provided on the ear plate. The guide slide extends into the edge strip, and the top of the guide slide is inclined towards the cutting direction. The end of the stabilizing plate is movably connected to a movable rod, which slides within a guide rail. When the support plate tilts upward, the movable rod slides along the guide rail and drives the elastic plate to extend outward from the movable chamber through the stabilizing plate.

[0010] Preferably, a limiting block is fixedly connected to the bottom end of the side wall of the edge strip; When the support plate flips downward and abuts against the limiting block, the support plate is horizontal.

[0011] Preferably, the support plate has an integrally formed arc-shaped end face at one end near the conveyor belt, and the arc-shaped end face is adapted to the outer contour of the arc-shaped bend of the conveyor belt; When the support plate is horizontal, a gap is reserved between the arc-shaped end face and the arc-shaped bend of the conveyor belt.

[0012] Preferably, a sharpening block is movably mounted on the end of the elastic plate away from the stabilizing plate, and the sharpening block is evenly distributed along the overall length of the cutter.

[0013] Preferably, a wear-resistant nylon pad is embedded at the contact point between the support plate and the cutter.

[0014] Preferably, the top of the workbench is provided with a second drive assembly that drives the conveyor belt to run; The second drive assembly includes a second motor and two rotating rollers; When the second motor is running, it drives the rollers fixed to it to rotate synchronously, and the conveyor belt feeds material in the forward direction or retracts material in the reverse direction.

[0015] Preferably, the support frame is provided with a first drive assembly that drives the cutter to reciprocate linearly; The first drive assembly includes a first motor, a wheel, and a transmission rod; When the first motor drives the rotating wheel to rotate, the transmission rod converts the rotational motion of the rotating wheel into the reciprocating linear lifting motion of the cutter in the vertical direction.

[0016] The technical effects and advantages of this invention are as follows: This invention protects the conveyor belt by setting up support plates and other structures, effectively preventing the force deviation during slicing, ensuring uniform slicing size of medicinal materials, and stable and reliable slicing operation. At the same time, the dynamic adjustment design of the support plates automatically cleans materials adhering to the blades, removes accumulated medicinal slices, and dissipates processing debris, ensuring the efficiency of the linear reciprocating medicine cutting machine.

[0032] Example 1

[0033] This invention provides, for example Figures 1 to 14 The linear reciprocating herb cutter shown includes a worktable 1, a support frame 3 fixedly mounted on the top of the worktable 1, and a cutter 4 that reciprocates along its height direction slidably on the support frame 3. The cutter 4 performs herb cutting by reciprocating linear motion up and down. A conveyor belt 2 is provided on the top of the worktable 1 for conveying the herb to be processed to the cutting position.

[0034] In traditional technology, cutting is usually performed in the middle of the conveyor belt 2, so that the cut herbs can continue to be conveyed to the next station until they fall from the end of the conveyor belt 2 into the collection box. However, when cutting from the middle of the conveyor belt 2, the blade of the cutter 4 will act on the surface of the conveyor belt 2 when it falls to cut, which can easily damage the conveyor belt 2. Therefore, the present invention improves the cutting position by setting the cutting position at the end of the conveyor belt 2 and providing a support mechanism. The support mechanism includes a support plate 7, which has an inclined state and a horizontal state. When the support plate 7 is in the horizontal state, it corresponds to the end of the conveyor belt 2 and temporarily acts as a cutting support surface for the herbs, preventing the cutter 4 from contacting the conveyor belt 2, while still enabling continuous conveying of the herbs. After cutting, the support plate 7 switches to the inclined state and guides the cut herbs to slide into the collection box.

[0035] In summary, this invention improves the cutting position and the supporting mechanism, thereby enabling the cutting and collection of medicinal materials during transportation.

[0036] Reference Figures 3 to 10As shown, the support plate 7 is a rectangular plate structure. When the support plate 7 is in a horizontal state, the blade of the cutter 4 is distributed vertically and vertically with the end of the support plate 7 closest to the conveyor belt 2. During the cutting process, the blade of the cutter 4 can directly act on the surface of the support plate 7. The cutting station where the support plate 7 contacts the blade is inlaid with a wear-resistant nylon pad. The pad is wear-resistant and corrosion-resistant, and can withstand long-term repeated cutting by the blade to reduce the wear of the support plate 7. At the same time, the hardness of the pad is lower than that of the cutter 4, which can buffer the cutting impact force, reduce the impact and wear of the blade of the cutter 4, and can be replaced regularly. Compared with replacing the conveyor belt 2, the equipment operating cost is reduced.

[0037] The upright frame 3 is equipped with side strips 5, and crossbars 6 are fixedly connected to the side strips 5. The crossbars 6 are distributed along the width direction of the conveyor belt 2. In actual use, two side strips 5 are set, and the crossbars 6 are fixed between the two side strips 5 to ensure the stability of the crossbars 6. The crossbars 6 can be adjusted according to the specific usage. The middle section of the support plate 7 is rotatably set on the crossbars 6, and a torsion spring 8 is fitted on the crossbars 6. One end of the torsion spring 8 is fixedly connected to the crossbars 6, and the other end of the torsion spring 8 is fixedly connected to the support plate 7. When no other external force is applied, the elastic support force of the torsion spring 8 causes the end of the support plate 7 closest to the conveyor belt 2 to tilt upward.

[0038] The support plate 7 has an integrally formed arc-shaped end face 701 at one end near the conveyor belt 2. The arc-shaped end face 701 is adapted to the outline of the arc bend of the conveyor belt 2. The bottom end of the side wall of the side strip 5 is fixedly connected to the limiting block 27, and the lower surface of the support plate 7 abuts against the limiting block 27. When the support plate 7 is flipped downward and abuts against the limiting block 27, the support plate 7 is horizontal. The arc-shaped end face 701 is close to the arc bend of the conveyor belt 2, and a small gap of less than 0.5mm is reserved between the two to avoid direct friction contact between the arc-shaped end face 701 and the conveyor belt 2. At the same time, the upper conveying surface of the conveyor belt 2 and the upper surface of the support plate 7 form a material conveying plane. The medicinal materials can be stably transferred from the conveyor belt 2 to the surface of the support plate 7 to avoid material jamming or leakage.

[0039] Reference Figure 3 and Figure 11 As shown, a synchronizing element is provided between the cutter 4 and the support plate 7 to achieve linkage between the cutter 4 and the support plate 7. The synchronizing element includes a mounting frame 9, an elastic telescopic rod 10, and a vertical rod 11. The mounting frame 9 is detachably mounted on the top of the side wall of the cutter 4 and is horizontally positioned. The top of the elastic telescopic rod 10 is fixed to the bottom of the mounting frame 9. The elastic support force of the elastic telescopic rod 10 is greater than the elastic support force of the torsion spring 8. The vertical rod 11 is detachably mounted on the bottom end of the elastic telescopic rod 10. The bottom end of the vertical rod 11 abuts against the support plate 7. The abutment position is located between the horizontal rod 6 and the conveyor belt 2 and is close to the horizontal rod 6. The bottom end of the vertical rod 11 is movably embedded with a structure such as ball bearings (not shown in the figure) to reduce wear between the vertical rod 11 and the support plate 7.

[0040] The actual working conditions are as follows: The first step involves controlling the cutter 4 to move downwards. The cutter 4 drives the vertical rod 11 and other structures to move downwards simultaneously. The bottom end of the vertical rod 11 abuts against the support plate 7, causing the support plate 7 to flip downwards at the end near the conveyor belt 2, so that the support plate 7 abuts against the limiting block 27. The arc-shaped end face 701 is close to the arc-shaped bend of the conveyor belt 2, and the upper conveying surface of the conveyor belt 2 and the upper surface of the support plate 7 form a conveying plane. Due to the large elastic support force of the elastic telescopic rod 10, the elastic telescopic rod 10 does not retract during this process.

[0041] In the second step, the conveyor belt 2 transports the medicinal materials to the support mechanism and then slides them onto the surface of the support plate 7. The cutter 4 continues to move downward, and the elastic telescopic rod 10 retracts synchronously. The cutter 4 cuts the medicinal materials placed on the support plate 7. During the cutting process, the cutter 4 acts directly on the surface of the support plate 7, completely avoiding the conveyor belt 2, thus protecting the conveyor belt 2. Compared with the conveyor belt 2, which is prone to slight vibration, the support plate 7 is fixed and limited during cutting, and remains stable as a whole, effectively preventing the force from shifting during cutting, ensuring that the medicinal materials are cut into uniform sizes and that the cutting operation is stable and reliable.

[0042] In the third step, the cutter 4 moves upward to reset, and the elastic telescopic rod 10 extends synchronously. However, the bottom end of the vertical rod 11 always abuts against the support plate 7, so that the support plate 7 maintains a horizontal support state. The conveyor belt 2 continues to transport the medicinal materials. After the medicinal materials arrive, the cutter 4 descends again to complete the cutting. That is, the cutting process relies on the extension and retraction of the elastic telescopic rod 10 to reserve the movement stroke space for the cutter 4 to move and cut, so that the two actions of positioning and supporting the support plate 7 and pressing down and cutting the cutter 4 are completed in steps, ensuring that the feeding and cutting processes are connected in an orderly manner.

[0043] After the set number of cuts is reached, the conveyor belt 2 briefly reverses direction, causing the medicinal materials to be cut to move in the opposite direction and be offset from the support plate 7. Then, the cutter 4 moves upward to reset. After the elastic telescopic rod 10 is fully extended, it pulls the vertical rod 11 upward to release the downward pressure limit on the support plate 7. Under the reset force of the torsion spring 8, the support plate 7 quickly flips and resets. During the flipping process, the support plate 7 swings rapidly and compresses the surrounding air to form an instantaneous airflow. The airflow washes over the surface of the cutter 4, blowing away the medicinal powder and dust adhering to the cutter body and the sticky tablets. At the same time, the tilted and flipped support plate 7 can completely export the tablets temporarily stored on it, which fall into the collection box placed below the support plate 7 to prevent excessive accumulation of tablets from obstructing the cutting station and ensuring the efficiency of subsequent cutting operations. In addition, the debris and residue generated during cutting slide off and are disposed of together, reducing the frequency of manual cleaning.

[0044] It should be noted that for some hard root and rhizome medicinal materials with few impurities and not easily sticking, such as astragalus and licorice, the support plate 7 can be turned over and cleaned every 6 to 12 cuts; for soft medicinal materials with high sugar content, high viscosity and a lot of dust, such as fresh rehmannia and polygonatum, the turning interval can be reduced, and the support plate 7 can be turned over and cleaned and discharged every 1 to 6 cuts.

[0045] In actual use, a positioning device (not shown in the figure) is also provided at the top of the workbench 1 near the supporting mechanism. The positioning device includes a pressure plate and other structures, which is used to position the medicinal materials on the conveyor belt 2 during the cutting operation to ensure the stability of the cutting and conveying operation. The positioning device and its working principle are common existing technologies, and will not be described in detail here.

[0046] In summary, by setting up structures such as the support plate 7, this invention achieves the purpose of protecting the conveyor belt 2, effectively preventing the force deviation during slitting, ensuring uniform slitting size of medicinal materials, and stable and reliable slitting operation. At the same time, by utilizing the dynamic adjustment design of the support plate 7, it automatically cleans the materials adhering to the blades, removes accumulated medicinal slices, and discharges processing debris, ensuring the efficiency of the linear reciprocating medicine cutting machine.

[0047] Reference Figures 3 to 10 As shown, to further prevent tablets from sticking together, a movable chamber 12 is provided on the arc-shaped end face 701. A telescopic assembly is provided inside the movable chamber 12. The telescopic assembly includes a stabilizing plate 13, an elastic plate 14, and a spring 15. The stabilizing plate 13 is slidably disposed inside the movable chamber 12. The elastic plate 14 is fixedly connected to the side of the stabilizing plate 13 near the conveyor belt 2. The elastic plate 14 is made of high-toughness and wear-resistant polyurethane material, which has both structural support strength and elastic deformation capability, and can be adjusted according to specific usage conditions. The spring 15 is located on the side of the stabilizing plate 13 facing away from the conveyor belt 2. One end of the spring 15 is fixedly connected to the stabilizing plate 13, and the other end of the spring 15 is fixedly connected to the inner wall of the movable chamber 12.

[0048] Reference Figure 4 , Figure 6 and Figure 8 As shown, a side slide 16 is provided on the side of the support plate 7. The side slide 16 is connected to the movable chamber 12. A side rod 17 is slidably provided inside the side slide 16. The side rod 17 is fixedly connected to the stabilizing plate 13. The side slide 16 and the side rod 17 are provided to ensure the stability of the sliding of the stabilizing plate 13 and the elastic plate 14.

[0049] Reference Figure 4 , Figure 6 , Figure 8 and Figure 9As shown, an ear plate 18 is fixedly connected to the top of the side strip 5. A guide slide 19 is provided on the ear plate 18. The guide slide 19 extends into the side strip 5, and the top of the guide slide 19 is inclined towards the cutter 4. A movable rod 20 is detachably installed on the side rod 17. The movable rod 20 slides in the guide slide 19. The side rod 17, the movable rod 20 and the guide slide 19 cooperate to guide the sliding of the stabilizing plate 13.

[0050] In actual use, when the support plate 7 is flipped to a horizontal state, the movable rod 20 slides to the bottom of the guide slide 19. At this time, the elastic plate 14 is completely retracted into the movable chamber 12 and will not bulge outward, so as not to affect the smooth overlap of the support plate 7 at the arc bend of the conveyor belt 2.

[0051] When the support plate 7 tilts upward near the end of the conveyor belt 2, the movable rod 20 slides along the guide slide 19, and the elastic plate 14 is driven to extend outward from the movable chamber 12 through the stabilizing plate 13. The elastic plate 14 abuts against the side of the blade of the cutter 4 and scrapes off the tablets adhering to the cutter 4. That is, by flipping the support plate 7, the extension and retraction of the elastic plate 14 are realized simultaneously, which is convenient to operate.

[0052] By relying on the airflow generated by the flipping and the physical scraping structure, the blade body is cleaned twice to effectively prevent tablets from sticking to the blade. In addition, the extended elastic plate 14 can fill the gap between the support plate 7 and the side of the cutter 4 blade, preventing tablets from falling into the equipment through the gap and ensuring stable and orderly discharge.

[0053] Furthermore, for some hard root and rhizome medicinal materials with few impurities and not easily sticking, such as astragalus and licorice, a pin or other structure can be used to fix the side rod 17 to the side slide 16 at the end away from the cutter 4, so that the elastic plate 14 is always retracted into the interior of the movable chamber 12, and the scraping function is canceled. Adjustments can be made according to the specific usage.

[0054] Reference Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 13 and Figure 14 As shown, considering that the blade of the cutter 4 is prone to dulling after long-term cutting of medicinal materials, the existing method usually requires the cutter 4 to be completely disassembled and individually ground and repaired. The disassembly and assembly process is cumbersome and the downtime is long. In order to improve the maintenance and grinding efficiency of the cutter 4, a grinding block 21 is movably assembled at the end of the elastic plate 14 away from the stabilizing plate 13. The grinding block 21 is evenly distributed along the overall length of the cutter 4. The grinding block 21 is integrally formed by high-strength wear-resistant plastic substrate and diamond microparticle grinding area. The grinding area can fit against the blade surface of the cutter 4 to complete uniform grinding and polishing. The grinding material is a common existing technology, which will not be described in detail here.

[0055] During the slitting stage, the grinding block 21 is removed from the elastic plate 14 and stored, which will not interfere with the transport and slitting of medicinal materials.

[0056] When the dulled blade of the cutter 4 needs to be sharpened, under the elastic support force of the torsion spring 8, the end of the support plate 7 near the conveyor belt 2 remains tilted upward. The elastic support force of the spring 15 pushes the stabilizing plate 13, and the elastic plate 14 extends outward stably. The vertical rod 11 is detached from the bottom of the elastic telescopic rod 10. At this time, the cutter 4 will not press down and cause the support plate 7 to reset and flip during the short downward movement. At the same time, the movable rod 20 is removed, and the operator can press down on the end of the support plate 7 away from the cutter 4 to separate the elastic plate 14 from the cutter 4, so that the sharpening block 21 can be assembled on the end of the elastic plate 14.

[0057] Next, release the support plate 7 and control the cutter 4 to move up and down vertically. Under the continuous pressing force generated by the torsion spring 8, the elastic plate 14 and the spring 15, the grinding block 21 always fits tightly against the side of the blade and rubs and grinds, providing uniform pressing force to ensure stable grinding force. Moreover, it is not necessary to disassemble the cutter 4 from the equipment as a whole, simplifying the maintenance process and reducing equipment downtime.

[0058] In actual use, the negative pressure suction pipe in the factory workshop is brought close to the cutter 4 to remove the debris generated during grinding in a timely manner.

[0059] Example 2

[0060] Reference Figure 1 and Figure 2 As shown, the support frame 3 is equipped with a first drive assembly that drives the cutter 4 to reciprocate linearly. The first drive assembly includes a first motor 23, a rotating wheel 24, and a transmission rod 25. The first motor 23 is fixedly installed on the top of the support frame 3. The rotating wheel 24 is fixed on the drive shaft of the first motor 23. One end of the transmission rod 25 is rotatably mounted on the disc surface of the rotating wheel 24 and is eccentrically arranged outside the center of the rotating wheel 24. The other end of the transmission rod 25 is rotatably mounted on the top of the cutter 4. In actual use, the first motor 23 drives the rotating wheel 24 to rotate. The eccentrically mounted transmission rod 25 converts the rotational motion of the rotating wheel 24 into the vertical reciprocating linear lifting motion of the cutter 4, thereby realizing the cutting of medicinal materials.

[0061] Reference Figure 1 and Figure 2As shown, a second drive assembly for driving the conveyor belt 2 is provided on the top of the workbench 1. The second drive assembly includes a second motor 26 and two rotating rollers 22. The two rotating rollers 22 are rotatably mounted at both ends of the top of the workbench 1 and are connected by the conveyor belt 2. The second motor 26 is fixed on the top of the workbench 1, and one of the rotating rollers 22 is fixed on the drive shaft of the second motor 26. The second motor 26 has forward rotation, reverse rotation and speed adjustment functions. When the second motor 26 is running, it drives the rotating roller 22 fixed to it to rotate synchronously, and the conveyor belt 2 feeds material in the forward direction or retracts material in the reverse direction.

[0062] Both the first motor 23 and the second motor 26 are connected to the factory's industrial power supply and are uniformly connected to the equipment's matching electrical control system. The electrical control system has a built-in programmable controller, operation display screen, and control buttons. Operators can input process parameters such as cutting frequency, feeding speed, single feeding stroke, and reverse unloading time through the display screen. The controller coordinates and controls the start and stop, output speed, and alternating working sequence of the first motor 23 and the second motor 26 according to the preset program. It can realize the automatic pause after the conveyor belt 2 is fed to the designated point, the cutter 4 continuously completes the set number of cuts, and the conveyor belt 2 short-term reverse unloading after the cut is completed. The entire process is fully automated, so that the up and down cutting action of the cutter 4 is linked with the forward feeding and reverse unloading action of the conveyor belt 2 without interference. The electrical control system is a common existing technology and will not be described in detail here.
