Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine production, and in particular to a pressing device for producing traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces refer to TCM preparations made into granules or tablets after a series of processing, extraction, and preparation techniques. They offer advantages such as convenient administration, easy storage, and stable efficacy. The production process involves first processing the raw materials to obtain the pressing material. This material is then placed in a pressing device, where its stamping mechanism shapes it, allowing it to solidify within a forming tank. This physical stamping method ensures a tighter fit between the materials. After pressing, the pieces are removed, and the process is repeated with new material. However, this method typically involves single-pass stamping, which can lead to incomplete stamping. Furthermore, it's difficult to replenish materials during the stamping process, increasing the probability of defective products. This single operation mode also hinders streamlined production and division of labor, resulting in reduced efficiency.

[0003] Therefore, in order to address the above problems, we are now developing a pressing device for the production of Chinese herbal medicine slices that allows for secondary stamping, facilitates temporary material replenishment, improves operational smoothness, and enables streamlined production. Summary of the Invention

[0004] To overcome the shortcomings of existing devices, which are typically single-press devices, prone to incomplete pressing and difficult to replenish materials during the pressing process, thus increasing the probability of defective products, and whose single operation mode makes it difficult to form a streamlined operation, hindering division of labor and cooperation and reducing efficiency, this invention provides a pressing device for the production of Chinese herbal medicine slices that performs secondary pressing, facilitates temporary material replenishment, improves operational smoothness, and realizes a streamlined operation.

[0005] The technical embodiment of the present invention is as follows: a pressing device for producing traditional Chinese medicine decoction pieces, comprising a base, a rotating frame rotatably mounted on the base, five feeding components mounted on the rotating frame, each feeding component having a pressing groove, five sliding seats slidably mounted on the base, the sliding seats being slidably connected to adjacent feeding components, a protective frame connected to the top of the base, and further comprising:

[0006] A pressing mechanism is installed on the protective frame. The pressing mechanism is used to perform secondary pressing on Chinese medicine materials and to assist in feeding materials during the processing.

[0007] A rotating mechanism is used to drive the rotating frame to rotate automatically.

[0008] Optionally, the pressing mechanism includes a mounting frame, which is connected to the upper side of the center position of the protective frame. Two hydraulic cylinders are connected to the mounting frame, and a first pressing frame is connected to the telescopic end of each hydraulic cylinder.

[0009] Optionally, the rotating mechanism includes a first gear, which is a ring structure and is installed on the outer edge of the rotating frame. A mounting seat is provided on the right rear part of the base, and a first drive motor is installed on the mounting seat. The output shaft of the first drive motor is oriented upwards, and a second gear is connected to the output shaft of the first drive motor. The second gear meshes with the first gear.

[0010] Optionally, it also includes a material feeding mechanism, which includes a mounting plate with a V-shaped structure. The mounting plate is installed in the notch area on the front side of the protective frame. A second lower pressure frame is connected between the top of the first lower pressure frame. A rotating plate is rotatably connected to the right side wall of the mounting plate. A sliding plate is slidably connected to the rear side of the rotating plate. A prying block is rotatably connected to the rear side of the sliding plate. A torsion spring is connected between the prying block and the sliding plate. A first spring is connected between the sliding plate and the rotating plate. A grooved rod is connected to the top of the rotating plate. A lifting plate is slidably connected to the upper right side of the mounting plate and slidably connected to the grooved rod. A second spring is connected between the lifting plate and the mounting plate.

[0011] Optionally, it also includes a pushing mechanism, which includes a second drive motor. The second drive motor is mounted on the front of the base. The output shaft of the second drive motor is oriented downwards. A lead screw is connected to the output shaft of the second drive motor. A lifting component is threaded onto the lead screw. The lifting component contacts the lower side of the protruding part at the front of the sliding seat.

[0012] Optionally, it also includes a covering mechanism, which includes a fixed seat. The fixed seat is connected above the feeding area of ​​the protective frame. There are two fixed seats, and a cover plate for dust protection is rotatably connected to the fixed seat.

[0013] Optionally, it also includes a placement mechanism, which includes a fixing sleeve. The fixing sleeve is bolted to the front side of the base, and a placement platform for temporarily placing the medicinal slices is engaged on the fixing sleeve.

[0014] Optionally, there is a gap between the outer edge of the sliding seat and the base.

[0015] Optionally, the protective frame has four partitioned areas, each including a feeding area and a pressing area, and the notch at the front of the protective frame is the discharge area.

[0016] A control method for a pressing device in the production of traditional Chinese medicine decoction pieces, the specific steps of which are as follows:

[0017] Step 1: First, open the cover and place the Chinese medicinal materials in the feeding area inside the protective frame. Then, start the first drive motor. As the output shaft of the first drive motor starts to rotate, it will drive the second gear to rotate, which will in turn drive the rotating frame to rotate.

[0018] Step 2: Simultaneously activate the hydraulic cylinder during the movement of the raw materials. After activation, the extension end of the hydraulic cylinder will push the first pressing frame downward, thereby pressing the Chinese medicine raw materials and allowing them to enter the pressing groove in the feeding part for shaping.

[0019] Step 3: Simultaneously, as the first pressing frame begins to move downwards and extrudes the material in the pressing area, the second pressing frame also moves downwards in sync, thereby pushing the lifting plate and causing it to slide downwards. The second spring is compressed, and the downward sliding of the lifting plate will drive the groove rod to rotate, thereby causing the rotating plate to flip to the left. During the process of the rotating plate flipping to the left, since the first spring is initially in a compressed state, the sliding plate will continuously move along the left side wall of the mounting plate and slide outwards continuously until the rotating plate rotates to its limit position. At this time, the sliding plate also slides to its limit position and sweeps the beverage slices in the discharge area to discharge during the movement of the rotating plate.

[0020] Step 4: When it is necessary to push the pressed and shaped beverage slices to discharge, simply start the second drive motor to make the lead screw rotate. After the lead screw starts to rotate, it will drive the lifting component to move upward, thereby pushing the sliding seat to move upward to complete the automatic discharge. The discharged beverage slices will be stacked on the placement platform.

[0021] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0022] 1. This invention divides the operating area into a feeding area, a pressing area, and a discharging area using a protective frame. During the pressing and molding process of Chinese herbal medicine slices, the hydraulic cylinder drives the first lower pressing frame to perform secondary pressing on the raw materials, improving the efficiency and effect of pressing and molding, making the slices more compact and avoiding looseness. At the same time, continuous rotation can effectively improve operating efficiency and facilitate assembly line operation.

[0023] 2. As the first pressing frame begins to move downward, the second pressing frame also moves downward synchronously, thereby pushing the lifting plate and causing the rotating plate to flip to the left. During the flipping of the rotating plate to the left, since the first spring is initially under compression, the sliding plate will continuously move along the left side wall of the mounting plate and slide outward continuously until the rotating plate reaches its limit position. At this time, the sliding plate will sweep the beverage pieces in the discharge area during the movement of the rotating plate. During this process, the paddle block can block the beverage pieces at the edge position to prevent the beverage pieces from falling from the left side. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] A pressing device for producing Chinese herbal medicine slices, such as Figures 1-3 As shown, the system includes a base 1, a rotating frame 2 rotatably mounted on the base 1, five feeding components 3 mounted on the rotating frame 2, each feeding component 3 having a pressing groove, five sliding seats 4 for rapid material discharge slidably mounted on the base 1, with a gap between the outer edge of the sliding seats 4 and the base 1, and a slidable connection between the sliding seats 4 and adjacent feeding components 3, a protective frame 5 connected to the top of the base 1, the protective frame 5 having four partitioned areas, including a feeding area and a pressing area, and a notch at the front of the protective frame 5 for the discharge area, and also includes: a pressing mechanism 6, mounted on the protective frame 5, used for secondary pressing of the Chinese medicine materials and assisting in material replenishment during the process; and a rotating mechanism 7, used to drive the rotating frame 2 to rotate automatically.

[0038] like Figure 1 and Figure 4 As shown, the pressing mechanism 6 includes a mounting frame 61. The mounting frame 61 is connected to the upper side of the center position of the protective frame 5. Two hydraulic cylinders 62 are connected to the mounting frame 61. The extension and retraction ends of the hydraulic cylinders 62 are both oriented downwards. A first pressing frame 63 for pushing and pressing the Chinese medicine material is connected to the extension and retraction ends of the hydraulic cylinders 62.

[0039] like Figure 1 and Figure 5As shown, the rotating mechanism 7 includes a first gear 71, which is a ring structure. The first gear 71 is installed on the outer edge of the rotating frame 2. A mounting seat 73 is provided on the right rear part of the base 1. A first drive motor 72 is installed on the mounting seat 73. The output shaft of the first drive motor 72 is oriented upwards. A second gear 74 is connected to the output shaft of the first drive motor 72. The second gear 74 meshes with the first gear 71.

[0040] It should be noted that when preparing Chinese herbal medicine slices, the raw materials of Chinese herbal medicine should first be placed in the feeding area within the protective frame 5. Then, the first drive motor 72 is started. As the output shaft of the first drive motor 72 starts to rotate, it drives the second gear 74 to rotate, which in turn drives the first gear 71 to rotate the rotating frame 2, thus causing the raw materials to move. During the movement of the raw materials, the hydraulic cylinder 62 is started simultaneously. After the extension end of the hydraulic cylinder 62 is started, it pushes the first pressing frame 63 downward, thereby pressing the raw materials of Chinese herbal medicine and causing them to enter the pressing groove in the feeding part 3 for forming. After the raw materials are formed, as the rotating frame 2 moves, the formed slices move to the notch position on the front side of the protective frame 5 and push the corresponding sliding seat 4 upward, causing the sliding seat 4 to push the slices in the feeding part 3 out. Finally, the operator can take out and collect the pushed-out slices.

[0041] Example 2

[0042] Based on Example 1, such as Figure 1 , Figure 6 and Figure 7 As shown, it also includes a feeding mechanism 8, which includes a mounting plate 81. The mounting plate 81 has a V-shaped structure and is installed in the notch area on the front side of the protective frame 5. A second lower pressure frame 82 is connected between the top of the first lower pressure frame 63. A rotating plate 83 is rotatably connected to the right side wall of the mounting plate 81. A sliding plate 84 is slidably connected to the rear side of the rotating plate 83. A blocking block 85 for blocking the medicine slices is rotatably connected to the rear side of the sliding plate 84. A torsion spring 86 is connected between the blocking block 85 and the sliding plate 84. A first spring 87 is connected between the sliding plate 84 and the rotating plate 83. A groove rod 88 is connected to the top of the rotating plate 83. A lifting plate 89 is slidably connected to the upper right side of the mounting plate 81 and is slidably connected to the groove rod 88. A second spring 810 is connected between the lifting plate 89 and the mounting plate 81.

[0043] It should be noted that as the first pressing frame 63 begins to move downwards to extrude and shape the material in the pressing area, the second pressing frame 82 also moves downwards simultaneously, thereby pushing the lifting plate 89 and causing it to slide downwards. The second spring 810 is compressed, and the downward sliding of the lifting plate 89 drives the groove rod 88 to rotate, causing the rotating plate 83 to flip to the left. During the leftward flipping of the rotating plate 83, since the first spring 87 is initially in a compressed state, the sliding plate 84 will continuously move along the left side wall of the mounting plate 81 and slide outwards continuously until the rotating plate 83 rotates to its limit position. At this time, the sliding plate 84 also slides to its limit position and sweeps the beverage pieces in the discharge area during the movement of the rotating plate 83. During this process, the pusher block 85 can block the beverage pieces at the edge to prevent them from falling from the left side.

[0044] like Figure 1 and Figure 8 As shown, it also includes a pushing mechanism 9, which includes a second drive motor 93. The second drive motor 93 is installed at the front of the base 1. The output shaft of the second drive motor 93 is oriented downwards. A lead screw 92 is connected to the output shaft of the second drive motor 93. A lifting component 91 is threadedly connected to the lead screw 92. The lifting component 91 contacts the lower side of the protruding part at the front of the sliding seat 4.

[0045] It should be noted that, in order to further improve the ease of operation and reduce manual intervention, when it is necessary to push the pressed and shaped beverage slices to discharge, the second drive motor 93 can be started directly to make the lead screw 92 rotate. When the lead screw 92 starts to rotate, it will drive the lifting component 91 to move upward, thereby pushing the sliding seat 4 to move upward to complete the automatic discharge.

[0046] like Figure 1 and Figure 9 As shown, it also includes a covering mechanism 10, which includes a fixed seat 101. The fixed seat 101 is connected above the feeding area of ​​the protective frame 5. There are two fixed seats 101, and a cover plate 102 for dust protection is rotatably connected to the fixed seat 101.

[0047] like Figure 1 and Figure 10 As shown, it also includes a placement mechanism 11, which includes a fixing sleeve 111. The fixing sleeve 111 is installed on the front side of the base 1 by bolts, and a placement platform 112 for temporarily placing the medicinal slices is snapped onto the fixing sleeve 111.

[0048] A control method for a pressing device in the production of traditional Chinese medicine decoction pieces, the specific steps of which are as follows:

[0049] Step 1: First, open the cover plate 102 and place the Chinese medicinal materials in the feeding area inside the protective frame 5. Then, start the first drive motor 72. As the output shaft of the first drive motor 72 starts to rotate, the output shaft of the first drive motor 72 will drive the second gear 74 to rotate, so that the first gear 71 can drive the rotating frame 2 to rotate.

[0050] Step 2: During the movement of the raw materials, the hydraulic cylinder 62 is activated simultaneously. After activation, the extension end of the hydraulic cylinder 62 will push the first pressing frame 63 downward to press the Chinese medicine raw materials, so that the raw materials enter the pressing groove in the feeding part 3 to be formed.

[0051] Step 3: Simultaneously, as the first pressing frame 63 begins to move downwards and extrudes the material in the pressing area, the second pressing frame 82 also moves downwards in sync, thereby pushing the lifting plate 89 and causing it to slide downwards. The second spring 810 is compressed by force, and the downward sliding of the lifting plate 89 will drive the groove rod 88 to rotate, thereby causing the rotating plate 83 to flip to the left. During the process of the rotating plate 83 flipping to the left, since the first spring 87 is initially in a compressed state, the sliding plate 84 will continuously move along the left side wall of the mounting plate 81 and slide outwards continuously until the rotating plate 83 rotates to the limit position. At this time, the sliding plate 84 also slides to the limit position and sweeps the beverage slices in the discharge area during the movement of the rotating plate 83.

[0052] Step 4: When it is necessary to push the pressed and shaped beverage slices to discharge, simply start the second drive motor 93 to make the lead screw 92 rotate. When the lead screw 92 starts to rotate, it will drive the lifting component 91 to move upward, thereby pushing the sliding seat 4 to move upward to complete the automatic discharge. The discharged beverage slices will be piled on the placement platform 112.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
