Description

Technical Field

[0001] This utility model relates to the technical field of medicinal material processing equipment, specifically to a CNC high-speed reciprocating cutting machine with noise reduction function. Background Technology

[0002] Traditional Chinese medicine (TCM) herbs are natural medicines and their processed products used under the guidance of TCM theory for the prevention, treatment, and diagnosis of diseases, as well as for rehabilitation and health maintenance. The sources of TCM herbs typically include plants, animals, and minerals. The cutting and processing of TCM herbs refers to the shaping and cutting of cleaned herbs. By cutting herbs into slices, segments, chunks, shreds, etc., it is easier to dispense and prepare the herbs. During the cutting and processing of herbs, the cutting blade and the equipment are prone to contact, friction, or collision, resulting in relatively high noise levels during the cutting process, which affects the normal work of the production personnel.

[0003] A search revealed Chinese Patent Publication No. CN217168615U, which discloses a CNC high-speed reciprocating herb-cutting machine with noise reduction function. The machine includes a frame, a feeding plate fixedly connected to one side of the inner wall of the frame, and a mechanical box fixedly connected to the feeding plate. A motor is fixedly connected to the bottom of the inner wall of the frame, and a transmission wheel is fixedly connected to the output end of the motor. By using this structure, the noise generated by the two cutting blades contacting the inner wall of the frame can be effectively reduced during the cutting of medicinal materials with the cooperation of two springs, thus improving its practicality.

[0004] Existing technologies often have the following problems when used:

[0005] The noise generated between the cutter and the equipment during the operation of the herb cutter is often mitigated by a single structure of buffer springs, which has a limited effect on noise reduction. Moreover, after repeated compression and reset, the springs are prone to elastic fatigue, which leads to a decrease in buffering force and still affects the noise reduction effect. Furthermore, the feeding method of traditional herb cutters is not precise and efficient enough, and the herbs are not smoothly fed during cutting, resulting in low cutting accuracy. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, this utility model provides a high-speed CNC reciprocating cutting machine with noise reduction function. This effectively solves the problems in existing technologies where the spring-driven noise reduction structure is prone to elastic fatigue, leading to a decrease in spring buffering force after prolonged use, thus affecting the noise reduction effect, and the problem of insufficient smooth material cutting and conveying resulting in low cutting accuracy.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a CNC high-speed reciprocating cutting and slicing machine with noise reduction function, comprising:

[0009] The outer frame has a feeding plate fixedly connected to its inner bottom surface and a buffer-type cutting component fixedly installed at its top.

[0010] The buffer-type cutting assembly includes two pneumatic push rods fixedly installed on the top of the outer frame. The telescopic ends of the two pneumatic push rods are fixedly connected to lifting rods. A cutter is fixedly connected to the lower end face of the lifting rod. Two buffer springs are fixedly connected to the upper end face of the feeding plate. A pressure plate is fixedly connected to the upper end of each of the two buffer springs. Silicone rubber gaskets are fixedly connected to the upper end face of the two pressure plates and the lower end face of the lifting rod. A secondary buffer component is fixedly connected to the upper end face of the feeding plate.

[0011] The outer frame sidewall is rotatably connected to a material conveying assembly.

[0012] Furthermore, a docking groove is provided on the feeding plate at a position directly below the cutter, and the inner diameter of the docking groove is larger than the outer diameter of the lower end of the cutter.

[0013] Furthermore, the secondary buffer component includes a sleeve fixedly connected to the upper end face of the conveyor plate, a T-shaped rod slidably connected to the inner wall of the sleeve, an air storage cavity formed between the lower end of the T-shaped rod and the inside of the sleeve, the air storage cavity being filled with compressed gas, and the upper end of the T-shaped rod being fixedly connected to the lower end face of the pressure plate.

[0014] Furthermore, the feeding assembly includes a ball screw rotatably connected to the side wall of the outer frame, a stepper motor fixedly installed on the outer wall of the outer frame, the output end of the stepper motor fixedly connected to the end of the ball screw, a slider threadedly connected to the ball screw, a pusher bracket fixedly connected to the outer wall of the slider, and the lower end of the pusher bracket slidingly engaging with the feeding plate.

[0015] Furthermore, the lower end of the pusher bracket is fixedly connected with several abutment protrusions.

[0016] Furthermore, the side wall of the conveying plate is provided with a sliding groove, and a discharge frame is slidably connected in the sliding groove.

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] This invention features a buffered herb-cutting assembly. Two pneumatic push rods with telescopic ends drive a lifting rod and a cutter to move up and down at high frequency. As the cutter descends, it cuts the herbs. Silicone rubber gaskets and buffer springs cushion the downward movement of the lifting rod and cutter, effectively reducing noise from the contact and collision between the cutter and the feed plate, preventing excessive cutting noise from affecting the workers' work. Furthermore, a secondary buffer component is included. When the lifting rod and cutter descend and compress the buffer spring, the lower end of the T-shaped rod simultaneously slides down relative to the inner wall of the sleeve, gradually compressing the compressed gas in the air storage chamber. This, combined with the buffer spring, further absorbs the impact force of the cutter during the cutting process, improving noise reduction. Simultaneously, the movement of the T-shaped rod relative to the sleeve slows down the rate of movement of the pressure plate and buffer spring, preventing excessive elastic fatigue of the buffer spring and maintaining the noise reduction effect.

[0019] This invention includes a feeding assembly that uses a stepper motor to drive a ball screw to rotate, which in turn allows a slider to move a pusher bracket. This allows the lower end of the pusher bracket to slide relative to the feeding plate, thus smoothly moving the medicinal material directly under the cutter and ensuring the cutting accuracy of the medicinal material.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: Refer to Figures 1 to 4 A high-speed CNC reciprocating cutting and cutting machine with noise reduction function includes an outer frame 1. A feeding plate 2 is fixedly connected to the bottom surface of the inner side of the outer frame 1. A sliding groove is opened on the side wall of the feeding plate 2, and a discharge frame 17 is slidably connected in the sliding groove. A buffer-type cutting assembly is fixedly installed at the top of the outer frame 1. The buffer-type cutting assembly includes two pneumatic push rods 3 fixedly installed at the top of the outer frame 1. A lifting rod 4 is fixedly connected to the telescopic end of the two pneumatic push rods 3. A cutter 5 is fixedly connected to the lower end of the lifting rod 4. A docking groove 9 is opened on the feeding plate 2 at a position directly below the cutter 5. The inner diameter of the docking groove 9 is larger than the outer diameter of the lower end of the cutter 5. Two buffer springs 6 are fixedly connected to the upper end of the feeding plate 2. A pressure plate 7 is fixedly connected to the upper end of each of the two buffer springs 6. Silicone rubber gaskets 8 are fixedly connected to the upper end of the two pressure plates 7 and the lower end of the lifting rod 4.

[0029] Specifically, the pneumatic push rod 3 adopts a compact linear pneumatic push rod of model CXSJM16-25. The two pneumatic push rods 3 are coupled in a closed series circuit with a controller and an external power supply. The controller has a built-in PLC and relay, which can control the synchronous extension and retraction of the extension ends of the two pneumatic push rods 3.

[0030] The lifting rod 4 and the cutter 5 are driven to move up and down at high frequency by the telescopic ends of the two pneumatic push rods 3. When the cutter 5 moves down, it can cut the medicinal materials. At the same time, the lifting rod 4 will contact and collide with the pressure plate 7 when it moves down. The silicone rubber gasket 8 is used to first reduce the collision noise. As the lifting rod 4 continues to move down, the buffer spring 6 can be used to buffer the downward movement of the lifting rod 4 and the cutter 5, thereby effectively reducing the noise generated by the contact and collision between the cutter 5 and the feeding plate 2, and avoiding excessive noise from cutting medicine that affects the work of the production personnel.

[0031] A secondary buffer component is fixedly connected to the upper end face of the conveyor plate 2. The secondary buffer component includes a sleeve 10 fixedly connected to the upper end face of the conveyor plate 2. A T-shaped rod 11 is slidably connected to the inner wall of the sleeve 10. An air storage chamber is formed between the lower end of the T-shaped rod 11 and the inside of the sleeve 10. The air storage chamber is filled with compressed gas. The upper end of the T-shaped rod 11 is fixedly connected to the lower end face of the pressure plate 7.

[0032] As the lifting rod 4 and the cutter 5 move down and compress the buffer spring 6, the lower end of the T-shaped rod 11 simultaneously slides down relative to the inner wall of the sleeve 10, causing the compressed gas in the gas storage chamber to be gradually compressed. This, combined with the buffer spring 6, can further absorb the impact force of the cutter 5 during the cutting process, improving the noise reduction effect. At the same time, the movement of the T-shaped rod 11 relative to the sleeve 10 can slow down the lifting and lowering rate of the pressure plate 7 and the buffer spring 6, preventing the buffer spring 6 from experiencing elastic fatigue too quickly, which is beneficial to maintaining the noise reduction effect.

[0033] A material conveying assembly is rotatably connected to the side wall of the outer frame 1. The material conveying assembly includes a ball screw 12 rotatably connected to the side wall of the outer frame 1. A stepper motor 13 is fixedly installed on the outer wall of the outer frame 1. The stepper motor 13 is model 42BYG250C-0401A. The output end of the stepper motor 13 is fixedly connected to the end of the ball screw 12. A slider 14 is threadedly connected to the ball screw 12. A pusher bracket 15 is fixedly connected to the outer wall of the slider 14. The lower end of the pusher bracket 15 contacts and slides with the material conveying plate 2. Several abutment protrusions 16 are fixedly connected to the lower end of the pusher bracket 15.

[0034] Specifically, the lower end of the pusher bracket 15 is in contact with the conveying plate 2 and slides, and the two sides of the pusher bracket 15 are also in contact with the inner wall of the outer frame 1. The stability of the pusher bracket 15 during horizontal movement ensures the stability of the medicinal material cutting and conveying.

[0035] When the medicinal materials are moved horizontally to cut and transport them, the stepper motor 13 is started. The stepper motor 13 drives the ball screw 12 to rotate, so that the slider 14 can drive the pusher bracket 15 to move. This allows the lower end of the pusher bracket 15 to slide relative to the feed plate 2, so as to push the medicinal materials smoothly to the bottom of the cutter 5 and ensure the cutting accuracy of the medicinal materials.

[0036] The working principle of this utility model is as follows:

[0037] In use, the prepared columnar medicinal material is first placed on the feeding plate 2 and pushed to move horizontally. When the part of the medicinal material to be cut moves directly below the cutter 5, the two pneumatic push rods 3 are activated. The extension and retraction ends of the two pneumatic push rods 3 drive the lifting rod 4 and the cutter 5 to move up and down at a high frequency. When the cutter 5 moves down, it can cut the medicinal material. At the same time, the lifting rod 4 will contact and collide with the pressure plate 7 when it moves down. The silicone rubber pad 8 is used to first alleviate the collision noise. As the lifting rod 4 continues to move down, the buffer spring 6 can be used to buffer the downward movement of the lifting rod 4 and the cutter 5, thereby effectively reducing the noise generated by the contact and collision between the cutter 5 and the feeding plate 2.

[0038] When the lifting rod 4 and the cutter 5 move down and squeeze the buffer spring 6, the lower end of the T-shaped rod 11 slides down relative to the inner wall of the sleeve 10 in a sealed manner, so that the compressed gas in the gas storage chamber is gradually compressed. With the help of the buffer spring 6, the impact force of the cutter 5 during the cutting process can be further absorbed.

[0039] When the medicinal materials are moved horizontally to cut and transport them, the stepper motor 13 is started, and the ball screw 12 is driven to rotate by the stepper motor 13, so that the slider 14 can drive the pusher bracket 15 to move, and the lower end of the pusher bracket 15 can slide relative to the conveyor plate 2 to push the medicinal materials to move smoothly to the bottom of the cutter 5.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
