[0039] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0040] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.
[0041] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.
[0042] See also Figure 1-7 The first embodiment provides a medicine cutter head structure, which is mainly used to be installed on a tool holder 500 of the medicine cutter to cut Chinese medicinal materials. The medicine cutter head structure mainly includes: a connecting piece 100, a blade 200, an adjustment block 300 and a rotating plate 400.
[0043] like Figure 3 , Figure 4 As shown in the figure, the connecting piece 100 is roughly in the shape of a rectangular parallelepiped, and is mainly used to connect the entire cutter head structure to the cutter holder 500 of the medicine cutter. Its edges parallel to the width direction of the conveyor belt 600 are relatively long, which is convenient for cutting more medicinal materials at the same time. Among them, a screw hole is provided on the side where the connecting piece 100 is connected to the cutter holder of the medicine cutter, and a detachable screw and screw hole connection with the cutter holder of the medicine cutter can be made by screws, so as to facilitate the replacement and cleaning of the cutter head. On the other side of the connecting piece 100, and located in the middle of the side, there is a slender blade groove 101 for installing the blade 200. At the same time, on the side surface where the blade groove 101 is located, and on both sides of the blade groove 101, there are two symmetrical adjustment grooves 103 for setting the adjustment block 300.
[0044] like Figure 3-Figure 5As shown in , the blade 200 is in the shape of a long sheet, which is arranged in the blade groove 101 on one side of the connecting member 100, and is used to directly contact the Chinese medicinal materials for cutting. Among them, the blade 200 is embedded in the blade groove 101 at one end as the insertion end 210, and the insertion end 210 is adapted to the shape of the blade groove 101, and its cross-section is roughly rectangular. The other opposite end of the blade 200 is a sharp edge end 220, which is used to cut Chinese medicinal materials. At the same time, the two sides between the insertion end 210 and the sharp edge end 220 are the wide sides 240 of the blade 200. In the part close to the insertion end 210, the wide sides 240 on both sides are parallel, and in the part close to the sharp edge end 220, the angle of the wide sides 240 on both sides is maintained between 18° and 22°, so as to ensure that the sharp edge end 220 has sufficient sharpness. Preferably, in this embodiment, the wide side surfaces 240 on both sides near the sharp edge end 220 are also provided with arc-shaped concave surfaces 242 with a slightly inward arc, so that during the process of cutting medicinal materials, some medicinal materials with strong viscosity are difficult to stably adhere to the wide side surfaces 240 on both sides of the part near the sharp edge end 220, thereby reducing the amount of cut medicinal materials attached to the wide side surfaces 240 and facilitating the cleaning of the blade 200 after use of the cutter head.
[0045] like Figure 3 , Figure 4 As shown in the figure, the adjustment block 300 is arranged on the connecting member 100 and is located in the adjustment slots 103 on both sides of the blade 200. The adjustment block 300 is adapted to the shape of the adjustment slots 103 on the connecting member 100, and is roughly in the shape of a rectangular parallelepiped, with one end of the adjustment block 300 embedded in the adjustment slot 103. In addition, a hinge hole is arranged on the other end of the adjustment block 300 for hingedly connecting the rotating plate 400, and the rotation center position of the rotating plate 400 is determined by setting the position of the hinge hole.
[0046] like Figure 6 , Figure 7 As shown in the figure, the rotating plate 400 is roughly in the shape of a rectangular plate, and is mainly used to keep the medicinal materials on the table below stable when the cutter moves up and down to cut the medicinal materials, so as not to flip and move at will. Among them, a rectangular notch 401 is set at one end of the rotating plate 400, and a hinge shaft 420 is set between the two inner side walls of the rectangular notch 401. The rotating plate 400 is hinged to the hinge hole on the adjustment block 300 through the hinge shaft 420. At the same time, two ear plates 430 are set at the other end of the rotating plate 400 near the two sides, and a pressure roller 440 is rotatably set at the other end of the rotating plate 400 through the ear plate through hole 431 in the middle of the ear plates 430 on both sides. The pressing roller 440 is mainly composed of a roller shaft 442 and a roller body 444. Both ends of the roller shaft 442 are rotatably set in the ear plate through hole 431, and the roller body 444 is sleeved therein. The roller body 444 is used for rolling contact with the cut Chinese medicinal materials. When the knife head is pressed down, the roller bodies 444 on both sides roll to both sides using the downward pressure and contact the medicinal materials below at the same time, compacting the cut Chinese medicinal materials below from the middle to both sides, thereby preventing the Chinese medicinal materials from flipping and moving.
[0047] A specific implementation of this embodiment is:
[0048] like Figure 1 , Figure 2 As shown in , before use, the cutter head structure of this embodiment is installed under the cutter holder 500 on the medicine cutting machine; after starting to use, first add the Chinese medicinal materials to be cut into the material tray 700 of the medicine cutting machine, and the medicinal materials fall onto the conveyor belt 600 through the bottom of the material tray 700, and are transported to the table 800 via the conveyor belt 600, and are cut by the cutter head structure installed under the cutter holder 500 above the table 800. Since the cutter head structure of this embodiment can keep the medicinal materials stable, it is not easy to flip and fall out, and it is not easy to move continuously, thereby ensuring that the specifications of the cut medicinal materials meet the requirements, and finally the cut medicinal materials are transported out through the discharge hopper 900 to enter the subsequent processing process.
[0049] In this embodiment, the cutter head structure of the medicine cutting machine is provided with a connecting piece 100, and adjustment blocks 300 and a rotating plate 400 are added on both sides of the blade 200. When the cutter head structure is pressed down to work, on the one hand, the blade 200 completes the cutting of the medicinal materials, and at the same time, the pressure rollers 440 on both sides of the rotating plate 400 also compact and press the cut Chinese medicinal materials from the middle to both sides, thereby avoiding the flipping and movement of the Chinese medicinal materials. This solves the problem in the prior art that when the cutter head of the chopping knife-type medicine cutting machine cuts the medicinal materials, the pressure of the cutter head easily causes the medicinal materials to flip and displace, easily causing the medicinal materials to fall out of the medicine cutting machine, and is not conducive to the control of the specifications of the medicinal materials.
[0050] Preferably, since one end of the pressure roller 440 of the rotating plate 400 may sometimes get stuck with the medicinal material and be inconvenient to move, the overall downward pressure of the cutter head may easily cause the pressure roller 440 to forcibly squeeze and crush the medicinal material. Therefore, in this embodiment, one end of the adjustment block 300 embedded in the adjustment groove 103 is also connected to the inner wall of the adjustment groove 103 through a spring, and the adjustment block 300 can slide in the adjustment groove 103, so that the adjustment block 300 and the rotating plate 400 have space to move up and down along the cutting direction, so as to avoid the pressure roller 440 of the rotating plate 400 getting stuck and forcibly squeezing the medicinal material when one end contacts the medicinal material.
[0051] Preferably, in this embodiment, in order to ensure the safety requirements of food and medicine, the blade 200 is preferably made of food-grade stainless steel; the adjustment block 300 and the rotating plate 400 are preferably made of food-grade plastic material, because the food-grade plastic material is light in texture and can also avoid crushing the cut medicinal materials. In addition, the adjustment block 300 and the rotating plate 400 can also be set to be hollow inside to reduce weight and relieve pressure.
[0052] In the above embodiment, the blade 200 is arranged in the blade groove 101 of the connecting member 100, and can be connected by snap connection, riveting or bolt crimping, screw hole connection, etc. However, even if a relatively stable screw hole connection method is adopted, there is still a problem that the blade 200 is easy to loosen after long-term use. In order to further solve these problems on the basis of the first embodiment, a second embodiment is provided below.
[0053] See also Figure 6 , Figure 7 In the second embodiment, the rotating plate 400 and the parts on both sides of the rectangular notch 401 are convexly arranged to form a fan-shaped portion 410. The part of the fan-shaped portion 410 close to the edge of the rotating plate 400 is a first arc surface 411; the part of the fan-shaped portion 410 close to the middle of the rotating plate 400 is a second arc surface 413. Among them, the diameter of the first curved surface 411 is greater than the diameter of the second curved surface 413. During the rotation of the rotating plate 400, when the blade 200 is pressed down but has not yet cut into the medicinal material to be cut below, the second curved surface 413 aligns with the wide side surfaces 240 on both sides of the insertion end 210 of the blade 200 and maintains a spacing therefrom, and there is no pressure between the rotating plate 400 and the blade 200; when the blade 200 is pressed down and cuts into the medicinal material to be cut below, the first curved surface 411 aligns and presses the wide side surfaces 240 on both sides of the insertion end 210 of the blade 200, and the rotating plates 400 on both sides apply left-right symmetrical pressure to the blade 200, thereby keeping the blade 200 stable and not loose during cutting. At the same time, since the second arc surface 413 is facing the wide side surfaces 240 on both sides of the insertion end 210 of the blade 200 when not cutting, the rotating plates 400 on both sides will not exert long-term pressure on the blade 200, thus avoiding the loosening caused by mutual extrusion deformation due to long-term maintenance of the clamped state.
[0054] Preferably, since the blade 200 is easily damaged or even broken due to being compressed too tightly, if the fragments of the broken blade enter the cut medicinal materials, a large amount of medicinal materials will be unusable. Therefore, in the second embodiment, an elastic material layer can be further provided on the first arc surface 411 so that the compressed blade has a certain elastic movement space when subjected to a large force perpendicular to the cutting direction, thereby reducing the risk of damage and breakage.
[0055] In addition, if Figure 4As shown in , bearings 450 can also be provided at the connection points between the two ends of the hinge shaft 420 and the rectangular notch 401, and the two ends of the hinge shaft 420 and the bearings 450 are connected by six radial springs 452. By providing the radial springs 452, on the one hand, the blade in the compressed state can also have a certain elastic movement space when subjected to a large force perpendicular to the cutting direction, thereby reducing the risk of damage and blade breakage; on the other hand, the rotating plate 400 can also have a space for telescopic movement, thereby preventing one end of the pressure roller 440 of the rotating plate 400 from getting stuck. It should be pointed out that the radial springs 452 of this embodiment are not limited to being provided in six, and can also be provided in five, seven, eight or other multiples.
[0056] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
