Description

Technical Field

[0001] This invention relates to the field of medicine cutting machine technology, and in particular to a variable frequency speed-regulating energy-saving linear reciprocating medicine cutting machine. Background Technology

[0002] The variable frequency speed-regulating reciprocating herb slicer is a commonly used specialized equipment for processing Chinese herbal medicine slices. The entire machine is made of stainless steel and mainly consists of a reciprocating cutting mechanism, a pressing and conveying mechanism, and a frame material collection assembly. The equipment relies on a connecting rod to drive the blade body to make linear reciprocating motion along the guide rail. With the help of a variable frequency speed-regulating energy-saving drive system, the cutting and feeding speeds are adjusted, which has an energy-saving effect. In conjunction with the crawler and pressure roller, the moistened Chinese herbal medicine is continuously conveyed. Each reciprocating stroke of the blade completes a single cut, which can process root, stem, vine, whole herb, and bark medicinal materials into uniform slices.

[0003] In actual production, the fine debris generated during the cutting of medicinal materials easily adheres to and accumulates on the cutting blade. If it is not removed in time, the debris will gradually dry and form medicinal scale, increasing the cutting friction resistance and causing an imbalance in the force during the cutting of medicinal materials. This easily produces substandard medicinal slices with uneven thickness and excessive fragments, while also accelerating the wear of the cutting blade and reducing its service life. Currently, the cutting blade surface is usually wiped and cleaned manually after the cutting operation or between batches. This is inefficient and cannot achieve real-time debris removal. The problem of medicinal debris accumulation continues during the operation, which also increases the labor intensity and makes it difficult to meet the requirements of continuous and stable production of equipment.

[0004] Therefore, it is necessary to propose a variable frequency speed-regulating energy-saving linear reciprocating medicine cutting machine to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a variable frequency speed-regulating energy-saving linear reciprocating medicine cutting machine to solve the problems of the existing method of manually wiping and cleaning the cutting surface after the cutting operation or between batches, which is inefficient, cannot achieve real-time chip removal, and still has the problem of continuous accumulation of medicine chips during operation, which also increases the labor intensity of manual labor and makes it difficult to meet the needs of continuous and stable production of equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a variable frequency speed-regulating energy-saving linear reciprocating medicine cutting machine, comprising a frame, a knife box that reciprocates along its height direction is arranged above the frame, and a cutting blade is rotatably arranged inside the knife box, the cutting blade dividing the inner cavity of the knife box into two sub-cavities; Both ends of the blade box are equipped with air compression mechanisms. The two sets of air compression mechanisms are connected to the two sub-cavities one by one, and the two connection positions are at different heights. The interior of the compartment is equipped with a slider, which is linked to the corresponding air compressor mechanism. During the slitting process, the blade box and the cutter move downwards, and the two sliders move synchronously to the upper half of the slitting chamber to fix the cutter, while the air compression mechanism draws in external gas. After slitting, the blade box and the cutter move upwards, the upper connecting position opens, and the corresponding air compressor supplies gas into the dividing chamber, pushing the cutter to swing to one side; the lower connecting position opens, and the corresponding air compressor supplies gas into the dividing chamber, pushing the cutter to swing to the other side.

[0007] Preferably, the air compression mechanism includes a side cavity opened inside the tool box wall, an inner plate is slidably disposed inside the side cavity, a sub-cavity is formed between the inner plate and the bottom of the side cavity, a longitudinal rod slidably passing through the bottom of the tool box is fixed to the bottom of the inner plate, and a spring for assisting the inner plate to reset is disposed inside the side cavity; An air intake channel is provided at the bottom of the sub-cavity, which is connected to the external atmospheric environment. An air intake one-way valve is fixedly installed inside the air intake channel. The bottom of the sub-cavity is provided with an air outlet channel, and the two air outlet channels are connected to the two sub-cavities one by one. An air outlet one-way valve is fixedly installed inside the air outlet channel.

[0008] Preferably, the longitudinal rod is provided with a docking assembly for connecting with the slider. The docking assembly includes a docking frame and two connecting plates. The docking frame is fixed at the bottom end of the longitudinal rod, and the two connecting plates are respectively fixed on both sides of the top of the docking frame. The top of the connecting plate is fixed to the bottom of the corresponding slider, and the connecting plate abuts against the inner wall of the cavity end.

[0009] Preferably, the connecting plate is attached to the inner wall of the cavity, and both the slider and the connecting plate are sealed and cooperated with the corresponding air outlet channel.

[0010] Preferably, the sliders are distributed along the length of the cutter and fit against the inner wall of the cavity.

[0011] Preferably, the slider has an inclined portion on the side near the cutter, and the inclined portion is located in the upper half of the slider.

[0012] Preferably, the tool box includes a box body, a cover plate, and bolts, with the box body and the cover plate engaging and being fixed by bolts.

[0013] Preferably, an ear plate is provided below the longitudinal bar, and the ear plate is fixedly connected to the frame. When the longitudinal rod moves downward with the tool box, the bottom end of the longitudinal rod abuts against the ear plate. Due to the limiting effect of the ear plate, the longitudinal rod drives the inner plate to move upward inside the side cavity.

[0014] Preferably, a conveyor belt is installed on the frame, and the conveyor belt is located below the ear plate.

[0015] Preferably, stabilizing rods are slidably provided on both sides of the frame, the knife box is fixed between the top ends of the two stabilizing rods, and a base plate is fixedly connected between the bottom ends of the two stabilizing rods; The frame is equipped with a motor, which is a variable frequency speed control motor. The motor drives the stabilizer bar to slide vertically back and forth along the frame via the base plate, and the cutter continuously cuts the medicinal materials.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention, by setting up a blade box, a cutter, and a slider, uses the linear reciprocating movement of the cutter as power to generate high-pressure gas to blow away residues on the blade. Combined with the swingable design of the cutter, it simultaneously achieves the functions of cleaning, heat dissipation, and anti-sticking, saving energy and protecting the environment, and improving the efficiency of the linear reciprocating medicine cutter. 2. By setting the two air outlets at different heights, the force on both sides of the cutter becomes unbalanced, loosening the dried residue that has hardened on the blade surface. Combined with synchronous blowing of directional high-pressure gas, the effect of peeling and cleaning the cutter residue is improved, further eliminating the problem of poor slicing caused by debris accumulation and adhesion.

[0032] This invention provides, for example Figures 1 to 14 The variable frequency speed regulation energy-saving linear reciprocating medicine cutting machine shown includes a frame 1, and a cutter 3 that moves reciprocally along the height direction of the frame 1 is arranged above the frame 1. When processing medicinal materials, the cutter 3 moves from top to bottom to cut the Chinese medicinal materials that are delivered to the position, producing slices. After the cutting is completed, the cutter 3 is lifted up and reset, and the cycle continues to complete the medicinal material cutting operation.

[0033] Considering that in the actual production process, the fine debris generated from cutting medicinal materials is very easy to adhere and accumulate on the cutter 3, if it is not removed in time, the debris will gradually dry and form medicinal scale, increasing the cutting friction resistance, causing the force imbalance in the cutting of medicinal materials, and easily producing unqualified medicinal slices with uneven thickness and excessive fragments. At the same time, it accelerates the wear of the cutter 3 and reduces the service life of the cutter 3. Currently, the surface of the cutter 3 is usually wiped and cleaned manually after the cutting operation or between batches. This is inefficient and cannot achieve real-time debris removal. The problem of medicinal debris accumulation still exists during the operation, which also increases the labor intensity of manual labor and makes it difficult to meet the requirements of continuous and stable production of equipment.

[0034] Therefore, the present invention provides a knife box 2 above the frame 1. The knife box 2 has an open bottom. The cutter 3 is located inside the knife box 2. The top of the cutter 3 is rotatably connected to the top of the inner cavity of the knife box 2. The bottom of the cutter 3 extends downward from the bottom of the knife box 2. The cutter 3 can swing inside the knife box 2. The cutter 3 divides the inner cavity of the knife box 2 into two sub-cavities 204. The cutter 3 includes a blade body 301 and a blade 302 from top to bottom. The side wall of the blade body 301 is vertical, and the side wall of the blade 302 is inclined. The blade 302 cuts the medicinal materials.

[0035] Reference Figure 4 , Figure 5 , Figures 10 to 14 As shown, both ends of the blade box 2 are equipped with air compression mechanisms. The air compression mechanism includes a side cavity 5 opened inside the wall of the blade box 2. An inner plate 6 is slidably arranged inside the side cavity 5. A rubber pad or other structure (not shown in the figure) is provided between the inner plate 6 and the inner wall of the side cavity 5 to reduce wear and ensure sealing. A sub-cavity 501 is formed between the inner plate 6 and the bottom of the side cavity 5. A longitudinal rod 7 is fixedly connected to the bottom of the inner plate 6. A through hole is opened at the bottom of the blade box 2 for the longitudinal rod 7 to slide. When no external force is applied, the bottom end of the longitudinal rod 7 is lower than the bottom end of the cutter 3. The top of the side cavity 5 has a pressure relief hole (not shown in the figure) that communicates with the external atmospheric environment to ensure that the inner plate 6 moves stably up and down.

[0036] An air inlet channel 11 is provided at the bottom of the sub-cavity 501, which is connected to the external atmosphere. An air inlet check valve 12 is fixedly installed inside the air inlet channel 11, which enables one-way flow from the external atmosphere to the sub-cavity 501. An air outlet channel 13 is provided at the bottom of the sub-cavity 501, and the two air outlet channels 13 are connected to the two sub-cavities 204 one by one. An air outlet check valve 14 is fixedly installed inside the air outlet channel 13, which enables one-way flow from the sub-cavity 501 to the sub-cavity 204. The top of the inner plate 6 is fixed. A spring 8 is connected, with its top end fixed to the top of the side cavity 5. The spring 8 has a large elastic support force. When the bottom end of the longitudinal rod 7 is squeezed, the inner plate 6 moves upward inside the side cavity 5, the sub-cavity 501 expands, and external gas enters the interior of the sub-cavity 501 through the air inlet channel 11. After the squeezing force is lost, the restoring force of the spring 8 can assist the inner plate 6 to move downward and reset, squeezing the sub-cavity 501, so that the gas is discharged from the air outlet channel 13 to the corresponding sub-cavity 204. When the inner plate 6 moves to the lowest position, it is still higher than the air inlet channel 11 and the air outlet channel 13.

[0037] Reference Figure 4 , Figure 5 , Figure 6 , Figure 12 , Figure 13 and Figure 14As shown, a slider 4 is slidably disposed inside the cavity 204. The slider 4 is distributed along the length direction of the cutter 3. The slider 4 fits against the inner wall of the cavity 204 and abuts against the cutter body 301.

[0038] The longitudinal rod 7 is equipped with a docking assembly for connecting with the slider 4. The docking assembly includes a docking frame 9 and two connecting plates 10. The docking frame 9 is detachably fixed to the bottom end of the longitudinal rod 7, and the two connecting plates 10 are respectively fixed to the two sides of the top of the docking frame 9. The top of the connecting plate 10 is fixed to the bottom of the corresponding slider 4. The connecting plate 10 abuts against the inner wall of the end of the cavity 204. The docking assembly allows the longitudinal rod 7 and the slider 4 to move synchronously, and both the slider 4 and the connecting plate 10 can block the corresponding air outlet channel 13. Specifically, the docking frame 9 is fixed to the bottom end of the longitudinal rod 7 with nuts or other structures, which makes disassembly and assembly convenient. The entire docking assembly can be disassembled from the longitudinal rod 7 simply by loosening the nuts, reducing the difficulty of equipment maintenance.

[0039] Reference Figure 14 When the two sliders 4 move upward synchronously, the sliders 4 and the blade 301 are distributed accordingly. The sliders 4 abut against the inner wall of the cavity 204 and the blade 301. At this time, the cutter 3 remains fixed to ensure stable downward movement and cutting. When the two sliders 4 move downward synchronously, the sliders 4 and the blade 302 are distributed accordingly. At this time, the cutter 3 can swing to shake off the residue.

[0040] Reference Figure 2 and Figure 3 As shown, an ear plate 101 is provided below the longitudinal rod 7. The ear plate 101 is made of high-strength stainless steel and is fixedly connected to the frame 1. When the longitudinal rod 7 moves downward with the knife box 2 and other structures, the bottom end of the longitudinal rod 7 abuts against the ear plate 101. Due to the limiting effect of the ear plate 101, the longitudinal rod 7 drives the inner plate 6 to move upward inside the side cavity 5.

[0041] The actual working conditions are as follows: The first step is to control the knife box 2 to move the cutting knife 3 and other structures downward. The bottom end of the vertical rod 7 contacts the ear plate 101. Due to the limiting effect of the ear plate 101, the vertical rod 7 drives the inner plate 6 to move upward inside the side cavity 5, the sub-cavity 501 expands, and the external gas enters the interior of the sub-cavity 501 through the air inlet channel 11.

[0042] Meanwhile, the longitudinal rod 7 drives the slider 4 to move upward inside the cavity 204 through the docking frame 9 and the connecting plate 10. The slider 4 abuts against the inner wall of the cavity 204 and the blade 301. The sliders 4 on both sides cooperate to keep the cutter 3 fixed and enter the cutting state. The slider 4 and the connecting plate 10 move against the inner wall of the cavity 204 to ensure the stability of the overall structure, and cover and block the air outlet channel 13 in sequence.

[0043] In the second step, the blade box 2 drives the cutting blade 3 and other structures to continue moving downwards, and the blade 302 cuts the medicinal materials; during this process, the longitudinal rod 7, inner plate 6 and other structures continue to be retracted.

[0044] In the third step, after the cutting is completed, the control knife box 2 drives the cutting knife 3 and other structures to move upward and reset. Under the reset force of the spring 8, the inner plate 6 moves downward and resets to squeeze the sub-cavity 501. In the initial stage, because the slider 4 and the connecting plate 10 block the air outlet channel 13, the gas in the sub-cavity 501 cannot be discharged from the air outlet channel 13 and is compressed and stored to form high-pressure gas.

[0045] Fourth step: When the slider 4 moves to correspond with the blade 302, the top of the slider 4 is offset from the air outlet channel 13, so that the air outlet channel 13 is opened; high-pressure gas is discharged from the air outlet channel 13 and blown into the gap between the slider 4 and the blade 302, blowing away the residue on the blade 302, and at the same time taking away some of the heat on the blade 302, extending its service life, achieving the effect of cleaning and heat dissipation, and using the moving and sealing effect of the slider 4 and the connecting plate 10 to ensure the gas pressure.

[0046] As the slider 4 moves to align with the blade 302, the cutter 3 has a small swing space, which, combined with the impact of the high-pressure airflow, further disperses the loose and attached residue.

[0047] In addition, high-pressure gas can also peel off and blow away the medicinal slices that are stuck to the blade 302, preventing them from sticking together and ensuring processing efficiency.

[0048] In summary, this invention, by setting up structures such as the blade box 2, the cutter 3, and the slider 4, utilizes the linear reciprocating movement of the cutter 3 as power to generate high-pressure gas to blow away residues on the blade 302. Combined with the swingable design of the cutter 3, it simultaneously achieves the functions of cleaning, heat dissipation, and anti-sticking, saving energy and protecting the environment, and improving the efficiency of the linear reciprocating medicine cutter.

[0049] Reference Figure 9 , Figure 12 and Figure 13As shown, the two air outlet channels 13 are at different heights. In actual use, the two sliders 4 move downwards synchronously. The corresponding slider 4 will first be offset from the higher air outlet channel 13. At this time, the other air outlet channel 13 is still blocked. That is, high-pressure gas enters one side of the chamber 204, while there is no high-pressure gas in the other side of the chamber 204. The cutter 3 is unbalanced in force on both sides. The cutter 3 will swing towards the side of the chamber 204 without high-pressure gas and contact the corresponding slider 4 to produce a shaking effect. When the lower air outlet channel 13 is opened, the cutter 3 will swing in the opposite direction. The shaking generated by the pressure on one side of the cutter 3 can loosen the dried residue solidified on the surface of the blade 302. Combined with the synchronous blowing of directional high-pressure gas, the peeling and cleaning effect of the residue of the cutter 3 is improved, and the problem of poor slicing caused by the accumulation and adhesion of debris is further eliminated.

[0050] Furthermore, the oscillation of the cutter 3 can change the position of the gas action, allowing high-pressure gas to scour all parts of the blade 302 from multiple angles, eliminating blind spots in the sweeping process.

[0051] In addition, a filter screen (not shown in the figure) is installed at the air intake channel 11. The filter screen adopts a fine stainless steel filter screen structure, which can block the medicinal dust and fine debris floating in the air from flowing into the sub-cavity 501 with the air intake airflow, and avoid subsequent impurities from clogging the air intake one-way valve 12 and the air outlet one-way valve 14, causing air circuit sealing failure, insufficient pressure and other malfunctions. The filter screen adopts a detachable installation structure, which can be quickly removed and cleaned by the operator during equipment shutdown maintenance and batch production intervals. After cleaning, it can be reinstalled to ensure smooth air intake and long-term stable operation of the entire pneumatic chip removal mechanism.

[0052] Reference Figure 12 As shown, the slider 4 is provided with an inclined part 401 on the side near the cutter 3. The inclined part 401 is located in the upper half of the slider 4. It can guide and gather the high-pressure airflow ejected from the air outlet 13, and guide the airflow to accurately concentrate and rush towards the area of ​​the dregs attached to the blade 302, thereby strengthening the blowing force. At the same time, the inclined structure can leave a gap between the slider 4 and the cutter 3, providing the cutter 3 with a larger swinging space and enhancing the effect of the cutter 3 shaking and dispersing the residue.

[0053] Reference Figures 4 to 9 As shown, the cutter box 2 includes a box body 201, a cover plate 202, and bolts 203. The box body 201 and the cover plate 202 are snapped together and fixed by bolts 203. Specifically, after the cutter 3 is installed inside the box body 201, the cover plate 202 is snapped onto the box body 201 and tightened by bolts 203 to complete the installation and fixing of the cutter 3. This splicing and assembly method facilitates the maintenance and replacement of the cutter 3.

[0054] Reference Figure 1 , Figure 2 and Figure 3As shown, a conveyor belt 26 is installed on the frame 1, located below the ear plate 101. The frame 1 is equipped with a drive motor and a transmission roller assembly to drive the conveyor belt 26 to rotate cyclically. The frame 1 also has positioning components, including pressure plates, used to squeeze and position the medicinal materials during the cutting process. In actual use, the medicinal materials are laid flat on the surface of the conveyor belt 26. The drive motor drives the transmission rollers to rotate, causing the conveyor belt 26 to transport the material forward at a uniform speed. The medicinal materials move along with the conveyor belt 26. The material moves towards the cutting station of cutter 3; during the movement, the positioning part presses down and adheres to the upper surface of the medicinal material to press and limit the material, preventing it from lifting, slipping, or shifting during the conveying and cutting process, ensuring that the material feed distance is uniform and stable, so that the slices cut by cutter 3 are of uniform thickness. The slices after slitting fall directly onto conveyor belt 26 and are continuously conveyed by conveyor belt 26 to the outside of the equipment to complete the discharge. The entire process of feeding, pressing, slitting, and discharging is carried out synchronously and continuously, ensuring stable and uninterrupted processing of the equipment.

[0055] Reference Figure 1 and Figure 2 As shown, to achieve linear reciprocating movement of the tool box 2, cutter 3, and other structures, stabilizing rods 15 are slidably installed on both sides of the frame 1. Wear-resistant copper sleeves are fitted at the sliding contact points between the stabilizing rods 15 and the frame 1. A small oil reservoir is opened in the inner hole of the copper sleeve to retain lubricating grease, continuously forming an oil film to isolate the reciprocating sliding contact surface of the stabilizing rods 15, reducing direct metal-to-metal friction wear. The tool box 2 is fixed between the top ends of the two stabilizing rods 15, and a base plate 23 is fixedly connected between the bottom ends of the two stabilizing rods 15. A rotating rod 16 is rotatably installed on the frame 1, with one end of the rotating rod 16 fixed... A transmission wheel 21 is fixedly connected to the transmission wheel 21. An eccentric rod 22 is fixedly connected to the side of the transmission wheel 21 facing away from the rotating rod 16. A transmission bar 25 is rotatably mounted on the eccentric rod 22. A fixed rod 24 is rotatably connected to the end of the transmission bar 25 away from the eccentric rod 22. The fixed rod 24 is fixedly connected to the base plate 23. A motor 18 is fixedly installed on the frame 1. The motor 18 is a variable frequency speed control motor. A second pulley 19 is fixedly installed on the drive shaft of the motor 18. A first pulley 17 is fixedly installed on the rotating rod 16. The first pulley 17 and the second pulley 19 are connected by a belt 20.

[0056] In actual operation, motor 18 adopts a variable frequency drive mode. Motor 18 is connected to a dedicated variable frequency controller to realize the variable frequency speed regulation function. The output speed of the motor can be precisely changed by adjusting the power supply frequency. The operator can flexibly adjust the equipment operating parameters according to different drug materials and the required slice thickness. Motor 18 drives the first pulley 17 and the second pulley 19 synchronously through belt 20, driving the rotating rod 16 and the transmission wheel 21 to rotate. During the rotation, the eccentric rod 22 performs eccentric circular motion, pushing and pulling the bottom plate 23 through the transmission bar 25, driving the two side stabilizing rods 1 5. The blade slides vertically back and forth along the frame 1, thereby driving the blade box 2 and the cutter 3 to rise and fall smoothly as a whole, realizing continuous cutting of medicinal materials; the frequency conversion speed regulation can match the reciprocating rising and falling frequency of the cutter 3. For hard root and stem medicinal materials, the speed can be reduced and the cutting speed can be slowed down, while for soft flower and leaf medicinal materials, the speed can be increased and the processing cycle can be accelerated. It does not need to operate continuously at full load, effectively reducing the power consumption under no-load and light-load conditions, and has the effect of energy saving; at the same time, the speed regulation is smooth and impact-free, reducing the impact wear of the eccentric transmission structure and extending the service life of the transmission components of the whole machine.
