Description

Technical Field

[0001] This utility model relates to the field of medicine cutting machine technology, and in particular to an automatic medicine feeding and cutting machine. Background Technology

[0002] In the medical and pharmaceutical fields, automatic medicine feeding and cutting machines are key equipment that undertake the important task of accurately cutting Chinese medicinal materials according to specific specifications and automatically transporting them to designated locations. This greatly improves the efficiency of drug production, reduces errors caused by manual operation, and ensures the stability of drug quality. They are widely used in hospital pharmacies, pharmaceutical factories, and Chinese medicine processing enterprises.

[0003] Early automatic herb feeding and cutting machines mainly consisted of a simple feeding device, fixed cutting blades, and a basic power drive. This structure was poorly adaptable to different shapes and textures of Chinese medicinal herbs, especially when cutting harder herbs, as the blades wore out easily, leading to frequent blade replacements. This affected production efficiency and increased costs. With technological advancements, existing automatic herb feeding and cutting machines have adopted adjustable blade angles, multiple cutting modes, and more durable blade materials to address the problems of earlier equipment. However, existing equipment still has shortcomings. When cutting herbs of varying hardness, the blades are prone to wear and damage. Because existing cutting machines use a motor to drive the blades to rotate at high speed, the blades are subjected to immense pressure when cutting hard herbs. Although the blade materials have been improved, during prolonged, high-intensity cutting, the serrations on the blade surface are prone to chipping and wear after frequent friction with hard herbs, resulting in poor cutting quality. This not only affects the cutting accuracy of the herbs but also requires frequent machine shutdowns for blade replacement, severely impacting the overall operating efficiency and production progress of the equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an automatic medicine feeding and cutting machine, comprising a U-shaped body 1 and an M-shaped feeding plate 6. An electric telescopic rod 3 is fixedly connected to the bottom of the inner wall of the U-shaped body 1. A servo motor 4 is fixedly connected to one end of the electric telescopic rod 3, and a cutting blade 5 is fixedly connected to the output end of the servo motor 4. Multiple limiting posts 7 are fixedly connected to the front and rear sides of the inner wall of the U-shaped body 1. The bottom of the M-shaped feeding plate 6 engages with the outer wall of the multiple limiting posts 7. The desired M-shaped feeding plate 6 is selected and placed above the limiting posts 7 for engagement and fixation. Two electric telescopic rods 8 are fixedly connected to the front and rear sides of the inner wall of the U-shaped body 1. A hollow slider 9 is fixedly connected to one end of each of the two electric telescopic rods 8. A push plate 10 is slidably connected to the right side of the inner wall of the M-shaped feeding plate 6. Activating the electric telescopic rods 8 moves the hollow slider 9. The movement of the hollow slider 9 will drive the push plate 10 to move together, which will push the Chinese medicinal materials above to the cutting blade 5. The bottom of the outer wall of the push plate 10 is engaged with the inner wall of the hollow slider 9. The cutting blade 5 will pass through the slit 11 located above the M-shaped feeding plate 6. When the M-shaped feeding plate 6 is placed, the bottom of the push plate 10 above it will be engaged with the top of the hollow slider 9. The top center of the M-shaped feeding plate 6 has a slit 11. The outer wall of the cutting blade 5 has multiple arc-shaped blades 12. The electric telescopic rod 3 is activated to drive the servo motor 4 and the structure above to move up and down together, thereby cutting the Chinese medicinal materials. At the same time, when the arc-shaped blades 12 rotate, they can easily cut hard Chinese medicinal materials. The front side of the outer wall of the U-shaped body 1 is provided with a vibration mechanism 2, which is used to make the M-shaped feeding plate 6 vibrate.

[0032] Specifically, select the required M-shaped feeding plate 6 according to the Chinese medicinal material to be cut, and place it above the limiting post 7 to lock and fix it. At this time, the cutting blade 5 will pass through the slit 11 located above the M-shaped feeding plate 6. When placing the M-shaped feeding plate 6, the bottom of the push plate 10 above it will lock with the top of the hollow slider 9. Then, place the medicinal material to be cut above the M-shaped feeding plate 6, and start the electric telescopic rod 8 to drive the hollow slider 9 to move. At this time, the movement of the hollow slider 9 will drive the push plate 10 to move together, which will push the Chinese medicinal material above to move towards the cutting blade 5. At the same time, start the servo motor 4 to drive the cutting blade 5 to rotate, and start the electric telescopic rod 3 to drive the servo motor 4 and the structure above to move up and down together, thereby cutting the Chinese medicinal material. At the same time, when the curved blade 12 rotates, it can easily cut hard Chinese medicinal materials, thereby avoiding easy damage to the cutting blade 5.

[0033] Reference Figure 1 , Figure 4 and Figure 5The vibration mechanism 2 includes a DC motor 201. The rear side of the DC motor 201 is fixedly connected to the top front side of the outer wall of the U-shaped body 1. The output end of the DC motor 201 passes through the U-shaped body 1 and is fixedly connected to an arc-shaped locking block 202. Multiple limiting posts 7 on the front and rear sides are slidably connected to U-shaped clamping plates 204. A grooved fixing block 203 is fixedly connected to the front side of the front U-shaped clamping plate 204. The inner wall of the grooved fixing block 203 engages with the rear side of the arc-shaped locking block 202. Multiple engaging holes 207 are provided on the outer wall of the limiting posts 7. Engaging bolts 205 are provided on both the left and right sides of the U-shaped clamping plate 204. The outer wall of 05 passes through the U-shaped clamping plate 204 and the limiting post 7 respectively. Multiple buffer springs 206 are fixedly connected to the outer wall of the U-shaped clamping plate 204. The other end of the buffer spring 206 is fixedly connected to the inner wall of the U-shaped body 1. When the DC motor 201 is started, the arc-shaped clamping block 202 is rotated. As it rotates, it pushes the groove fixing block 203 to move to the rear, thereby driving the U-shaped clamping plate 204 and the M-shaped feeding plate 6 above to move to the rear. Then, under the action of the buffer spring 206, the M-shaped feeding plate 6 will be reset, so that the groove fixing block 203 will re-engage with the arc-shaped clamping block 202.

[0034] Specifically, for some Chinese medicinal materials containing impurities, after placing them on top of the M-shaped feeding plate 6, the DC motor 201 is started to drive the arc-shaped clamping block 202 to rotate. As it rotates, it pushes the groove fixing block 203 to move backward, thereby driving the U-shaped clamping plate 204 and the M-shaped feeding plate 6 above to move backward together. Then, under the action of the buffer spring 206, the M-shaped feeding plate 6 will be reset, so that the groove fixing block 203 will re-engage with the arc-shaped clamping block 202, thereby allowing the M-shaped feeding plate 6 to move back and forth above the limiting post 7. This makes it easier for the impurities on the Chinese medicinal materials to be vibrated and fall off. The M-shaped feeding plate 6 and the U-shaped clamping plate 204 can be connected by the clamping bolt 205, so that the impurities can be better vibrated off before the Chinese medicinal materials are cut.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A nameplate 13 is fixedly connected to the front left side of the outer wall of the U-shaped body 1, and a warning sign block 14 is fixedly connected to the middle side of the front side of the outer wall of the U-shaped body 1; a limit groove 15 is opened on the front and rear sides of the right side of the inner wall of the U-shaped body 1, and the inner walls of the two limit grooves 15 are slidably connected to the outer wall of the hollow slider 9; a column 17 is fixedly connected to the rear top of the U-shaped body 1, and an alarm light 18 is fixedly connected to the top of the column 17.

[0036] Specifically, the nameplate 13 allows operators to quickly obtain basic information about the equipment upon first contact or during daily use. When maintenance, repair, or upgrades are needed, the information on the nameplate 13 can be quickly retrieved, greatly improving the efficiency of equipment management and maintenance. The warning sign block 14 reminds operators to pay attention to potential dangers around the equipment, preventing accidents caused by negligence and providing important protection for the personal safety of operators. The limit groove 15 provides precise guidance and limit for the movement of the hollow slider 9, ensuring that the hollow slider 9 can only slide along the direction and range specified by the limit groove 15. The column 17 provides installation space for the alarm light 18, which can use a conspicuous light signal to alert operators. Even if operators are far away or distracted, they can promptly detect abnormalities in the equipment and take appropriate measures to prevent further damage to the equipment and reduce production stoppages and economic losses caused by equipment failure.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The top of the M-shaped feeding plate 6 has multiple filter holes 19, which can filter the medicinal materials when they are placed. The inner wall of the M-shaped feeding plate 6 is rounded to reduce the friction of the medicinal materials during placement and movement. A controller 16 is fixedly connected to the front right side of the U-shaped body 1. The controller 16 is electrically connected to the electric telescopic rod 3, the servo motor 4, the electric telescopic rod 8, and the DC motor 201. The controller 16 can control the starting and running power of the electric telescopic rod 3, the servo motor 4, the electric telescopic rod 8, and the DC motor 201 respectively. The bottom thickness of the M-shaped feeding plate 6 is the same as the inner wall thickness of the U-shaped clamp 204, ensuring that the M-shaped feeding plate 6 can be tightly and securely installed in the U-shaped clamp 204. The bottom notch of the M-shaped feeding plate 6 is the same as the outer diameter of the limiting post 7, so that the M-shaped feeding plate 6 can be accurately engaged with the limiting post 7 through the bottom notch.

[0038] Specifically, the filter hole 19 can screen and filter the medicinal materials when they are placed. The rounded inner wall of the M-shaped feeding plate 6 can reduce the friction of the medicinal materials during placement and movement, preventing damage to the medicinal materials due to friction. This is especially true for some more fragile medicinal materials, which can better maintain their integrity. It also makes the sliding of the medicinal materials on the feeding plate smoother, which helps the subsequent feeding mechanism to push the medicinal materials steadily to the cutting area. The controller 16 can control the starting and running power of the electric telescopic rod 1 3, servo motor 4, electric telescopic rod 2 8 and DC motor 201 respectively. The bottom thickness of the M-shaped feeding plate 6 is consistent with the inner wall size of the U-shaped clamp 204, which ensures that the M-shaped feeding plate 6 can be tightly and securely installed in the U-shaped clamp 204. The bottom notch size of the M-shaped feeding plate 6 is consistent with the outer wall diameter of the limiting post 7, which allows the M-shaped feeding plate 6 to be accurately engaged with the limiting post 7 through the bottom notch.

[0039] Working principle: First, according to the type of Chinese medicinal material to be cut, select an appropriate M-shaped feeding plate 6 and place it on the limiting post 7 to ensure a stable engagement. The cutting blade 5 will pass through the slit 11 above the M-shaped feeding plate 6. When placing the M-shaped feeding plate 6, the bottom of the push plate 10 engages with the upper end of the hollow slider 9. Then, place the Chinese medicinal material to be cut on the M-shaped feeding plate 6, activate the electric telescopic rod 8 to move the hollow slider 9, and then drive the push plate 10 to move synchronously, pushing the Chinese medicinal material forward towards the cutting blade 5. At the same time, activate the servo motor 4 to rotate the cutting blade 5, and activate the electric telescopic rod 3 to drive the servo motor 4 and the upper structure to move up and down to complete the cutting operation of the Chinese medicinal material. During this process, the arc-shaped blade 12 can easily handle hard Chinese medicinal materials when rotating, effectively avoiding damage to the cutting blade 5.

[0040] Furthermore, through the vibration mechanism 2, the Chinese medicinal materials containing impurities are placed on the M-shaped feeding plate 6, and the DC motor 201 is started to drive the arc-shaped clamping block 202 to rotate. During the rotation, the arc-shaped clamping block 202 pushes the groove fixing block 203 to move backward, thereby causing the U-shaped clamping plate 204 and the M-shaped feeding plate 6 to move backward synchronously. Under the action of the buffer spring 206, the M-shaped feeding plate 6 is reset, and the groove fixing block 203 and the arc-shaped clamping block 202 are re-engaged. This process allows the M-shaped feeding plate 6 to move back and forth under the guidance of the limiting post 7, thereby promoting the vibration and removal of impurities above the Chinese medicinal materials. Through the locking bolt 205, the M-shaped feeding plate 6 and the U-shaped clamping plate 204 can be stably connected to ensure that the impurities of the Chinese medicinal materials are effectively removed by vibration before cutting.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
