Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traditional Chinese medicine decoction pieces, and particularly relates to a traditional Chinese medicine decoction piece processing equipment. BACKGROUND

[0002] Traditional Chinese medicine decoction pieces are traditional Chinese medicines which are processed by traditional Chinese medicine theory and traditional Chinese medicine decocting methods, and can be directly used in traditional Chinese medicine clinics. As one of the three main pillars of the Chinese traditional medicine industry, traditional Chinese medicine decoction pieces are the traditional weapons necessary for the diagnosis and treatment of traditional Chinese medicine clinics, and are important raw materials for Chinese patent medicines. The unique decocting theory and method of traditional Chinese medicine decoction pieces embody the profound wisdom of ancient Chinese medicine. With the continuous improvement and maturity of the decocting theory, traditional Chinese medicine decoction pieces have become an important means for the prevention and treatment of traditional Chinese medicine clinics. However, the following problems still exist in the processing of current traditional Chinese medicine decoction pieces.

[0003] 1. When the current traditional Chinese medicine decoction piece production equipment is used to cut traditional Chinese medicines with more juice, the cut traditional Chinese medicines are prone to adhere to the cutter. The cut pieces adhered to the cutter are prone to fall below the cutter in the subsequent cutting process, so that the cutter cuts the already cut traditional Chinese medicines again, thereby cutting the traditional Chinese medicine pieces into pieces, which affects the cutting quality of the traditional Chinese medicines.

[0004] 2. The cutter assembled in the current traditional Chinese medicine decoction piece cutting equipment is generally a vertical cutter, which cannot cut the traditional Chinese medicines at an angle, and has poor applicability.

[0005] 3. When the traditional Chinese medicines are cut, a large amount of broken residues are often generated, which will affect the quality of the traditional Chinese medicine decoction pieces. In order to ensure the quality of the traditional Chinese medicine decoction pieces, subsequent screening is required, which further increases the processing cost. SUMMARY

[0016] Beneficial effects

[0017] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0018] 1. By setting up a cutting component, the present invention can automatically move the cutter horizontally a certain distance after the Chinese medicinal materials are cut, then raise the blade and scrape off the slices of medicinal materials on the cutter with a scraper. After scraping, the cutter is driven to reset, so that it is away from the scraper and the scraped-off slices of medicinal materials. Thus, when the slices are scraped off, they will not fall under the cutter, preventing the slices of medicinal materials from being crushed during subsequent cutting, thereby ensuring the cutting quality of the medicinal materials and reducing the loss of medicinal materials.

[0019] 2. By setting an adjustment component and rotating the front door frame, the present invention can drive the deflection of the cutting component through the cooperation of the lead screw, worm gear, and worm, thereby cutting the medicinal materials at multiple angles, which has strong applicability;

[0020] 3. By setting up a screening and feeding component and driving the screening and feeding component through the movement of the cutter, the debris generated during the slicing of Chinese medicine can be screened out, ensuring the quality of the Chinese medicine slices;

[0021] 4. Through the linkage of the various components of the present invention, the present invention only requires a first motor and a first electric push rod to cut, screen and adjust the cutting angle of Chinese medicinal materials, without the need for other electrical control equipment. The structure is compact, highly integrated and saves equipment costs. Attached Figure Description

A first pin 272 located behind the connecting block 242 is slidably connected to the right side of the front door frame 2 in the vertical direction. The slider 25 has a first sliding rod 241 slidably connected to the connecting block 242. A third spring 26 is sleeved on the first sliding rod 241, which forces the connecting block 242 to drive the cutter 243 forward. A rotating block 8 is rotatably connected inside the front door frame 2. The upper end of the rotating block 8 has an upper convex shaft 8a that extends upward from the front door frame 2. A second gear 84 is fixedly installed at the upper end of the upper convex shaft 8a. A vertical sliding groove 291 is provided inside the front door frame 2. A second track groove is provided on the outer circumference of the rotating block 8. A second pin 28 is provided on the first slider 25, which passes through the vertical sliding groove 291 and extends into the second track groove. When the rotating block 8 rotates, the second pin 28 moves up and down in cooperation with the vertical sliding groove 291 and the second track groove. A scraper 23 is fixedly provided on the front side of the front door frame 2. When the cutter 243 is in the front position, the scraper 23 abuts against the front side of the cutter 243, and as the cutter 243 moves upward, the scraper 23 moves downward relative to the cutter 243.

[0041] In this embodiment, the second track groove includes an upper arc groove 812 and a lower arc groove 811, as well as a first spiral groove 83 and a second spiral groove 82 for connecting the upper arc groove 812 and the lower arc groove 811. When the second pin 28 is in the upper arc groove 812, the first slider 25 is in the upper position. As the rotating block 8 rotates, the second pin 28 enters the first spiral groove 83 and drives the first slider 25 to move downward along the first spiral groove 83. When the second pin 28 enters the lower arc groove 811, the first slider 25 is in the lower position. As the rotating block 8 continues to rotate, the second pin 28 enters the second spiral groove 82 and drives the first slider 25 to move upward along the second spiral groove 82. When the second pin 28 enters the upper arc groove 812, the first slider 25 is in the upper position again.

[0042] In this embodiment, the first track groove includes a first vertical groove 221, a first horizontal groove 222 that communicates with the lower end of the first vertical groove 221 and extends forward, a second vertical groove 223 that communicates with the front end of the first horizontal groove 222 and extends upward, and an inclined groove 224 for the upper end of the second vertical groove 223 and the upper end of the first vertical groove 221; wherein a stepped surface 211 is provided between the upper end of the inclined groove 224 located on the right side of the front door frame 2 and the upper end of the first vertical groove 221, the stepped surface 211 is used to prevent the first pin 272 from entering the inclined groove 224 from the upper end of the first vertical groove 221; when the first slider 25 drives the connecting block 242 to move downward, the first pin 272 moves downward along the first vertical groove 221, and the first pin 272 moves to the connection between the first vertical groove 221 and the first horizontal groove 222. At the moment of contact, the first slider 25 is in the lower position, the connecting block 242 moves forward under the action of the third spring 26, and the first pin 272 enters the first horizontal groove 222. When the first pin 272 moves to the connection between the second vertical groove 223 and the first horizontal groove 222, the cutter 243 is in the front end position. As the first slider 25 drives the connecting block 242 to move upward, the first pin 272 enters the second vertical groove 223. As the first slider 25 continues to move upward, the first pin 272 enters the inclined groove 224. Under the action of the first pin 272 and the inclined groove 224, the connecting block 242 compresses the third spring 26 backward. When the first slider 25 moves to the upper position, the first pin 272 passes through the inclined groove 224 and enters the upper end of the first vertical groove 221, and the cutter 243 is in the rear end position.

[0043] The screening and feeding assembly includes a screen 54 hinged to the front support 11, the screen 54 being located directly above the first material trough 56, and the outlet of the screen 54 being located directly above the second material trough 57; a tension spring 55 is provided between the front support 11 and the screen 54, the tension spring 55 being used to force the screen 54 to flip downwards; a lever 51 is slidably connected to the left side of the front door frame 2 in the vertical direction, the lever 51 having a protrusion 51a located on the second vertical groove 223; the... A pulley 53 is rotatably connected to the left side plate 1c. A pull rope 52 is provided between the lever 51 and the screen 54 on the pulley 53. When the first pin 272 on the left side of the cutter 243 is located in the second vertical groove 223 and moves upward, the cutter 243 drives the lever 51 to move upward through the protrusion 51a. The lever 51 drives the screen 54 to flip upward through the pull rope 52. When the cutter 243 disengages from the protrusion 51a, the screen 54 flips downward and resets under the action of the tension spring 55.

[0044] A gear frame 32 is rotatably connected to the upper end of the front door frame 2. A third gear 332 and a fourth gear 331 are rotatably connected inside the gear frame 32. A first motor 31 for driving the third gear 332 to rotate is fixedly provided at the upper end of the gear frame 32. A first electric push rod 34 is hinged to the upper end of the front door frame 2. The telescopic end of the first electric push rod 34 is hinged to the gear frame 32. When the first electric push rod 34 extends, the third gear 332 meshes with the first gear 411, and the fourth gear 331 disengages from the second gear 84. When the first electric push rod 34 retracts, the third gear 332 disengages from the first gear 411, and the fourth gear 331 meshes with the second gear 84.

[0045] The traditional Chinese medicine decoction piece processing equipment in this embodiment includes the following steps during operation:

[0046] Step 1: When it is necessary to use this invention to cut medicinal materials, firstly, (as shown in the image) Figure 5 As shown), the first electric push rod 34 extends, and through the gear bracket rod 321 rotatably connected to it, pushes the gear carrier 32, which is rotatably connected to the fixed shaft 292 of the front door frame 2, to rotate (as shown). Figure 8 (As shown), this causes the fourth gear 331 to disengage from the second gear 84 and the third gear 332 to mesh with the first gear 411.

[0047] When the first motor 31 is started, it drives the third gear 332 to rotate, which in turn drives the first gear 411, which meshes with it, to rotate. Since the first gear 411 and the worm 413 are fixedly connected through the first rotating shaft 412, and the worm 413 is engaged with the worm wheel 42, and the worm wheel 42 is threadedly connected to the lead screw 44 on the rotating frame 43, it drives the worm wheel 42 to rotate. Also, since the worm wheel 42 is limited between the two lugs 2a on the front door frame 2, the left rotating shaft 293 at the bottom left end of the front door frame 2 (as shown in the image) Figure 2 As shown, the rotating frame 43 is rotatably connected to the upper end of the left side plate 1c. The limiting shaft 431 at the bottom of the rotating frame 43 slides in the limiting groove 12, so that when the worm gear 42 rotates and slides on the lead screw 44, it can drive the front door frame 2 to deflect.

[0048] When the worm gear 42 reaches the foremost position of the lead screw 44 (as shown in the image) Figure 3 As shown), the limiting shaft 431 at the bottom of the rotating frame 43 slides to the rightmost side of the limiting groove 12, and the front door frame 2 moves to the maximum angle away from the even roller 62. When the worm gear 42 reaches the rearmost side of the lead screw 44 (as shown), Figure 4 As shown), the limiting shaft 431 at the bottom of the rotating frame 43 slides to the leftmost side of the limiting groove 12, and the front door frame 2 moves to the maximum angle close to the uniform roller 62.

[0049] By controlling the direction and number of rotations of the first motor 31, the front door frame 2 can be adjusted to the desired cutting angle, and then the first motor 31 can be stopped.

[0050] At this time, the first electric push rod 34 is retracted, which drives the gear frame 32 to deflect, causing the third gear 332 to disengage from the first gear 411 and the fourth gear 331 to mesh with the second gear 84, thus completing the selection of the cutting angle of the cutter 243.

[0051] Step 2: After selecting the cutting angle of the cutter 243, start the conveyor belt 7 and place the medicinal materials to be cut at the feeding position 71 above the conveyor belt 7. The conveyor belt 7 transports the medicinal materials to be cut from the feeding position 71 to the feeding position 72. When the medicinal materials are transported to the bottom of the leveling component, the wheel frame 63 is slidably connected to the rear door frame 61 and is pushed downward by the first spring 64. This causes the medicinal materials to come into contact with the leveling roller 62 rotatably connected to the wheel frame 63 when passing through the leveling component, and the force of the first spring 64 presses the medicinal materials evenly. When the medicinal materials move to the bottom of the cutting component, the continuous feeding is completed.

[0052] Step 3: While feeding materials, start the first motor 31, which drives the fourth gear 331 meshing with it through the third gear 332. At the same time, since the fourth gear 331 meshes with the second gear 84, it drives the second gear 84 (e.g., ...). Figure 10 The rotation causes the rotating block 8, which is fixedly connected to the second gear 84, to rotate.

[0053] At this time, since the first slider 25 is slidably connected to the front door frame 2, the first slider 25 is fixedly connected to the second pin 28, and the second pin 28 is slidably engaged with the vertical slide groove 291, the rotating block 8 (as shown in the image) Figure 11 (As shown) It is rotatably connected to the front door frame 2. Simultaneously, due to the connecting block 242, it is slidably connected to the first slider 25 via the first slide rod 241. When the first pin 272 is at the uppermost end of the first vertical groove 221, under the action of the stepped surface 211 within the first vertical groove 221, the connecting block 242 overcomes the force of the third spring 26, causing the connecting block 242 to retract backward. If the second pin 28 is in the upper arc groove 812 within the rotating block 8 (as shown)... Figure 14 When the first slider 25 is in its highest position, as the rotating block 8 rotates, the second pin 28 enters the first spiral groove 83 from the upper arc groove 812. Under the guidance of the first spiral groove 83, the second pin 28 gradually slides downward, thereby driving the connecting block 242 to slide downward. The first pin 272 slides downward along the first vertical groove 221 under the action of the step surface 211, causing the cutter 243 fixedly connected to the connecting block 242 to press down, thereby cutting the medicinal material.

[0054] As the rotating block 8 rotates, when the second pin 28 enters the lower arc groove 811 from the first spiral groove 83, the first pin 272 arrives at the connection between the first vertical groove 221 and the first horizontal groove 222. Under the action of the third spring 26, it pushes the connecting block 242 to slide along the first horizontal groove 222 until the first pin 272 arrives at the connection between the first horizontal groove 222 and the second vertical groove 223. At this time, the cutter 243 is close to the scraper 23, and the cut Chinese herbal medicine slices are pushed forward by the cutter 243. As the rotating block 8 continues to rotate, the second pin 28 enters the second spiral groove 82 from the guide lower arc groove 811. At this time, the second pin 28 moves upward with the first slider 25, the first pin 272 enters the second vertical groove 223, and the connecting block 242 moves upward. Since the cutter 243 is close to the scraper 23 at this time, the scraper 23 scrapes off the herbal medicine slices adhering to the cutter 243 during the upward movement of the cutter 243.

[0055] When the first pin 272 enters the inclined groove 224 from the second vertical groove 223, the first pin 272 slides upward, overcoming the force of the second spring 271, causing the first pin 272 to retract. At the same time, under the action of the inclined groove 224, the connecting block 242 overcomes the force of the third spring 26 and gradually retracts.

[0056] When the second pin 28 returns from the second spiral groove 82 to the upper arc groove 812, the first pin 272 disengages from the inclined groove 224, crosses the step surface 211, and enters the top of the first vertical groove 221. Simultaneously, under the force of the second spring 271, the first pin 272 is tightly attached to the bottom of the first vertical groove 221. Furthermore, under the action of the step surface 211, it overcomes the force of the third spring 26 to position the connecting block 242, thus forming a cycle. This allows the rotating block 8 to continuously slice the medicinal material instead of the cutting blade 243, avoiding the problem of the slices being broken during the slicing process, and completing the slicing of the medicinal material.

[0057] Step 4: When the sliced ​​medicinal materials are fed onto the screen 54 via the feeding position 72 of the conveyor belt 7, the cutting component continuously processes the medicinal materials. As the first pin 272 descends along the first vertical groove 221, the cutter 243 follows. When the first pin 272, under the force of the third spring 26, reaches the junction of the first horizontal groove 222 and the second vertical groove 223, the left end of the cutter 243 is directly below the lever 51 slidably connected in the groove 294. As the first pin 272 enters the second vertical groove 223 and moves upward, the cutter 243 pushes the lever 51 upward via the protrusion 51a. Since the lever 51 is fixedly connected to the pull rope 52, and the pull rope 52 is limited by the pulley 53, the screen 54 is rotatably connected to the front via the connecting frame 541. On the support 11, when the pry block 51 rises with the cutter 243, the pull rope 52 pulls the screen 54 to overcome the force of the tension spring 55 and lifts the screen 54 slightly upward. When the first pin 272 enters the inclined groove 224, the cutter 243 moves backward, causing the left end of the cutter 243 to disengage from the protrusion 51a. Due to the force of the tension spring 55, the pry block 51 is pulled back, and the screen 54 returns to its original position, thereby screening the slices on the screen 54. The fine fragments of medicinal materials fall into the first material trough 56 below the screen 54, and the slices fall into the second material trough 57 along the screen 54, completing the screening and feeding of the slices.

[0058] Step 5: Repeat steps 2 to 4 to complete the slicing and sieving of the medicinal materials.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
