Description

Technical Field

[0001] The invention relates to the technical field of medicinal material processing, and in particular to a medicinal material dicing device. Background Art

[0002] Poria cocos is the dried sclerotium of the fungus Poria cocos of the family Polyporaceae. A single Poria cocos is spherical, elliptical, oblate or irregular. As a commodity, Poria cocos is usually sold in dices. Therefore, it is necessary to perform rough processing on Poria cocos, that is, to cut the lumped Poria cocos into small dices of balanced size. For example, the Chinese invention patent application with application publication number CN110524617A discloses a Poria cocos precise dice cutting device, wherein it is disclosed that the device is provided with a receiving tank (i.e., a material storage tank) for accommodating Poria cocos, a booster (i.e., a material push plate) for pushing the movement of Poria cocos is provided on one side of the receiving tank, and a knife plate (i.e., a knife group) is also provided on the end of the receiving tank away from the booster. The knife plates are arranged in parallel to cut the Poria cocos into slices, and then an intermittent conveyor belt is used to transport the sliced ​​Poria cocos to the knife group, and the knife group includes a plurality of crisscross blades, and the sliced ​​Poria cocos is cut into dices using the knife group. In order to spread the sliced ​​Poria cocos that passes through the knife plate into a layer on the conveyor belt, a slicing limiter is also provided. The sliced ​​Poria cocos is spread on the conveyor belt through the slicing limiter to form a thin layer that fits the conveyor belt, and then cut into pieces using the knife group.

[0003] However, in the above technical solution, the blades are arranged vertically and in parallel. After the Poria cocos passes through the blades, it is cut into flakes. At this time, the flakes of Poria cocos are placed vertically on the conveyor belt. After passing through the slicing limiter, the flakes of Poria cocos will fall down and lie flat on the conveyor belt under the blocking effect of the slicing limiter. That is, the medicinal materials cut into flakes need to be transported by the conveyor belt before being diced. In order to keep it flat, a slicing limiter needs to be set, and the structure is relatively complicated. In addition, in the process of falling down and paving flat, the Poria cocos at the edge may be pushed out of the conveyor belt by the Poria cocos in the middle. That is to say, only the flakes of Poria cocos in the middle will remain on the conveyor belt, and the Poria cocos at the edge will fall off the conveyor belt, resulting in a second operation to complete the dicing of all the Poria cocos. Summary of the invention

[0004] The object of the present invention is to provide a medicinal material dicing device to solve the problem of complex structure caused by the prior art that the medicinal materials are first cut into vertical slices and then flattened by a conveyor belt and a slice limiter before being diced.

[0005] In order to achieve the above-mentioned purpose, the medicinal material dicing equipment in the present invention adopts the following technical scheme:

[0006] A medicinal material dicing device comprises a feeding trough for placing medicinal materials, wherein a material push plate and a knife group are respectively arranged in the feeding trough, the material push plate is used to push the medicinal materials to move toward the knife group, and the knife group is fixedly arranged on the feeding trough, and the knife group comprises a first cutter and a second cutter whose cutting direction is consistent with the movement direction of the material push plate and are arranged perpendicular to each other, the first cutter and the second cutter respectively have a plurality of parallelly arranged first cutters and the plurality of first cutters and the second cutters form a grid shape, and a cutting knife whose cutting direction is reciprocating and perpendicular to the pushing direction of the material push plate is also arranged downstream of the knife group.

[0007] The beneficial effect of the above technical solution is that the present invention improves the existing medicinal material dicing equipment by setting a first cutter and a second cutter perpendicular to each other, and the first cutter and the second cutter each have a plurality of cutters arranged in parallel, so that the projections of the two cutters in the cutting direction are in a grid shape, which is convenient for cutting the medicinal material into strips; in addition, since the cutting directions of the first cutter and the second cutter are consistent with the movement direction of the material push plate, that is, consistent with the movement direction of the medicinal material, then in the process of the medicinal material being pushed, the thrust of the material push plate is directly used, and the medicinal material will be cut into strips along the direction of the movement of the medicinal material in length. The long strips of medicinal materials are then cut into dices by a cutting knife whose cutting direction is perpendicular to the movement direction of the material push plate and which reciprocates, that is, the medicinal materials are already in strips before being cut into dices. The medicinal strips do not need to be flattened and can be directly cut, that is, there is no need to change the direction of the medicinal materials, so there is no need to set a slicing limiter, which simplifies the structure, thereby solving the problem of complex structure caused by the prior art that the medicinal materials are first cut into vertical slices and then flattened by a conveyor belt and a slicing limiter, and then diced.

[0008] Furthermore, the medicinal material dicing equipment also includes a push plate transmission mechanism that is transmission-connected to the material push plate to control the reciprocating motion of the material push plate and / or a cutting knife transmission mechanism that is transmission-connected to the cutting knife to control the reciprocating motion of the cutting knife.

[0009] The beneficial effects of the above technical solution are: it is easy to design the machine, and the two transmission mechanisms are arranged to facilitate the operation of the material push plate and the cutting knife.

[0010] Furthermore, the push plate transmission mechanism includes a dial-in wheel, a driving shaft for driving the material push plate to move, and a fixing member, wherein the driving shaft includes a gear segment meshing with the dial-in wheel for transmission and a threaded segment for threaded cooperation with the fixing member.

[0011] The beneficial effect of the above technical solution is that the driving shaft can convert the rotational motion of the dial-in wheel into forward screwing motion through the gear segment and the thread segment, which is convenient for pushing the material.

[0012] Furthermore, the end of the threaded section away from the gear section is connected to the material pushing plate through a ball buckle, so that the pushing shaft and the material pushing plate can rotate relative to each other.

[0013] The beneficial effect of the above technical solution is that the ball buckle is provided so that the rotational motion of the driving shaft is transmitted to the material pushing plate and converted into linear motion.

[0014] Furthermore, the dial-in wheel comprises a dial-in toothed segment meshing with the gear segment and a dial-in toothless segment stopping the movement of the driving shaft.

[0015] The beneficial effect of the above technical solution is that it is easy to make the material move intermittently, so that it can be cut when the material stops moving, ensuring that the cut pieces are more balanced.

[0016] Furthermore, the cutting knife transmission mechanism includes a cutting wheel and cam teeth meshing with the cutting wheel for transmission, and the cam teeth are connected to the cutting knife through the cam mechanism to drive the cutting knife to reciprocate.

[0017] The beneficial effect of the above technical solution is that the reciprocating operation of the cutting knife is facilitated.

[0018] Furthermore, the knife shifting wheel comprises a knife shifting toothed section meshing with the crank wheel and a knife shifting toothless section stopping the crank wheel from moving.

[0019] The beneficial effect of the above technical solution is that it is easy to make the cutting knife move intermittently, so that the material can be cut after it moves to a corresponding length, ensuring that the diced pieces are more uniform.

[0020] Furthermore, the cutting knife transmission mechanism includes a cutting wheel and cam teeth meshing with the cutting wheel for transmission, the cam teeth are connected to the cutting knife through the cam mechanism to drive the cutting knife to reciprocate; the cutting wheel includes a toothed cutting section meshing with the crank wheel and a toothless cutting section that stops the crank wheel from moving; the cutting wheel and the advancing wheel are installed on the same driving shaft, and a matching structure for matching with the rotating power source is provided on the driving shaft, and the toothless advancing section and the toothed cutting section correspond to each other along the axial direction, and the toothed advancing section and the toothless cutting section correspond to each other along the axial direction, so that when the toothed cutting section is meshing with the crank wheel for transmission, the toothless advancing section cooperates with the gear section, and when the toothed advancing section is meshing with the gear section for transmission, the toothless cutting section cooperates with the crank.

[0021] The beneficial effects of the above technical solution are: the material pushing plate and the cutting knife are linked, that is, the cutting knife will not move when the material is pushed by the material pushing plate; when the material stops moving, the cutting knife cuts it, thereby making the size of the dices cut by the cutting knife more uniform, and during the cutting process of the cutting knife, the medicinal materials will not push against the side of the cutting knife, thereby protecting the knife.

[0022] Furthermore, the first cutter and the second cutter are arranged with an interval in front and back.

[0023] The beneficial effect of the above technical solution is to avoid the need to cut a large area at one time and reduce the cutting resistance each time.

[0024] Furthermore, the cutting knife is arranged beside the knife group, so that when the front end of the medicinal material is cut into medicinal strips while the rear end is still connected as a whole, the cutting knife can cut the medicinal strips into medicinal dices.

[0025] The beneficial effect of the above technical solution is that before dicing, the front end of the medicine strip becomes a strip-shaped medicine strip, while the rear end is still in a connected state, so that the medicine strips are also in a state of interconnection, so that before being diced, the medicine strips will not fall off the device, avoiding the problem of the medicinal materials scattering everywhere during the cutting process of the cutting knife.

DETAILED DESCRIPTION

[0032] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0033] In Embodiment 1 of the medicinal material dicing device of the present invention:

[0034] In this embodiment, a material storage trough and a material pushing plate are provided to push the medicinal materials so that the medicinal materials move in the material storage trough, and a knife group and a cutting knife are sequentially provided on the moving path of the medicinal materials, wherein the knife group includes a plurality of horizontally arranged first cutting knives and a plurality of vertically arranged second cutting knives, that is, a grid is formed inside the knife group, and the medicinal materials are cut into long strips connected to the medicinal material body after passing through the knife group, and then the strip-shaped medicinal materials (i.e., medicinal strips) are cut into dices (i.e., medicinal dices) by the cutting knife.

[0035] like Figure 1 and Figure 2 As shown, the medicinal material dicing device in this embodiment includes a trough 1 for placing medicinal materials. Specifically, the trough 1 includes a horizontally arranged bottom plate and two vertically arranged side plates fixedly connected to the bottom plate, and a space for placing medicinal materials is formed between the bottom plate and the two side plates. A knife group is fixedly arranged at one end of the trough 1, and a material push plate 21 is arranged at the end of the trough 1 away from the knife group. The material push plate 21 is used to push the medicinal materials in the trough 1 to move toward the knife group. A reciprocating cutting knife 41 with a cutting direction perpendicular to the pushing direction of the material push plate 21 is also arranged downstream of the knife group. In addition, the medicinal material dicing device also includes a transmission mechanism for pushing the material push plate 21 to move and the electric cutting knife 41 to move, wherein the part connected to the material push plate 21 in transmission constitutes a push plate transmission mechanism, and the part of the transmission mechanism connected to the cutting knife 41 constitutes a cutting knife transmission mechanism.

[0036] like Figure 1 and Figure 3 As shown, the knife group includes a plurality of vertically arranged first cutters 31 and a plurality of horizontally arranged second cutters 32. The cutting directions of the first cutters 31 and the second cutters 32 are consistent with the moving direction of the material push plate 21, and the first cutters 31 are arranged upstream of the second cutters 32. That is to say, the projections of the first cutters 31 and the second cutters 32 in the cutting direction are in a grid shape. After passing through the knife group, the medicinal materials are cut into long strips. In this embodiment, the spacing between two adjacent first cutters 31 is 1CM, and the spacing between two adjacent second cutters 32 is also 1CM, so that after passing through the knife group, a long strip of medicinal materials with a square cross section is formed. Since the distance between the cutting knife and the knife group is relatively close, the long strip of medicinal materials cut by the knife group will not fall off the medicinal material body but will be fixedly connected to the medicinal material body. Then naturally, the long strip of medicinal materials at this time does not need to be transported by a conveyor belt, and can be directly cut under the action of the cutting knife to avoid the medicinal materials falling during the transportation process.

[0037] like Figure 1As shown, the material push plate 21 is a rectangular plate, the edge of which fits with the edge of the material trough 1 to facilitate the pushing of the material. A driving shaft 23 for pushing the material push plate 21 is also provided on the side of the material push plate 21 away from the knife group. The driving shaft 23 includes a screw section close to the material push plate 21 and a gear section away from the material push plate 21. A guide section 233 away from the screw section is also provided on the gear section. The medicinal material dicing equipment also includes a guide plate 25 that cooperates with the guide section 233 and a fixing member that cooperates with the screw section thread. The screw section is connected to the material push plate 21 through a ball buckle 22. In this embodiment, the fixing member is a fixing plate 24 with a threaded hole, and the guide plate 25 is a plate with a light hole. The gear section on the driving shaft 23 is a gear section 232 that is linked to the output end of the pushing plate. The guide section 233 is a round rod, and the threaded section 231 is threadedly matched with the threaded through hole on the fixing plate 24. The screw segment and the material push plate 21 are connected by a ball buckle 22, and the ball buckle 22 allows the push shaft 23 and the material push plate 21 to rotate relative to each other. That is to say, the push shaft 23 in the push plate transmission mechanism is driven first, and then the push shaft 23 moves linearly. Due to the existence of the screw segment and the fixing part, the screw produces a rotational motion, which drives the material push plate 21 to move through the ball buckle 22.

[0038] like Figure 2 As shown, the cutting knife 41 is provided with a guide rod 42 for guiding the movement of the cutting knife 41, wherein the cutting knife transmission mechanism includes a cam 43 hinged with the guide rod 42 and a cam tooth 44 for driving the cam 43 to reciprocate, the cam tooth 44 is coaxially arranged with the cam 43, and the rotation of the cam tooth can drive the rotation of the cam, thereby driving the rotation of the guide rod 42. The cutting knife 41 is fixedly connected with the guide rod 42, and the guide rod 42 can reciprocate up and down under the action of the cam 43, thereby enabling the cutting knife 41 to reciprocate. In this embodiment, the cam tooth 44 is a spur gear, and the output end of the cutting knife 41 also includes a knife shifting wheel 45 meshing with the cam tooth 44. The knife shifting wheel 45 and the dialing wheel 26 are connected through the same driving shaft 51, that is, the knife shifting wheel 45 and the dialing wheel 26 can be linked.

[0039] like Figure 2 and Figure 5As shown, the medicinal material dicing equipment also includes a motor 53 and a transmission 52 that are power-connected to the drive shaft 51. In addition, in order to enable the material push plate 21 and the cutting knife 41 to intermittently move, the advance wheel 26 and the knife shifting wheel 45 are both configured as toothless gears with missing teeth. The advance wheel 26 includes a toothed advance segment 261 and a toothless advance segment 262 that mesh with the gear segment, and the knife shifting wheel 45 includes a knife shifting tooth segment and a knife shifting toothless segment that mesh with the cam gear 44. The toothless advance segment 262 and the knife shifting tooth segment correspond to each other along the axis direction, and the toothed advance segment 261 and the knife shifting toothless segment correspond to each other along the axis direction, so that when the knife shifting tooth segment meshes with the crank wheel for transmission, the toothless advance segment cooperates with the gear segment, and when the toothed advance segment meshes with the gear segment for transmission, the toothless advance segment cooperates with the crank. Thus, when the knife wheel 45 can drive the cutting knife 41 to move, the toothless section 262 on the wheel 26 cooperates with the gear section, so the material push plate 21 will not move forward; when the wheel 26 drives the material push plate 21 to move, the toothless section on the knife wheel 45 corresponds to the cam tooth 44, so the cutting knife 41 will not move. Through the linkage between the cutting knife 41 and the material push plate 21, the medicinal material is pushed out by the material push plate 21 for a certain length and then paused before being cut. This makes the medicinal material not move forward during the cutting process of the cutting knife, so the size of the cut pieces is uniform. In addition, since the medicinal material does not move forward at this time, the side of the cutting knife facing the medicinal material is prevented from being abutted by the strip medicinal material, which is convenient for protecting the cutting knife. And the length is exactly the length of the driving shaft 23 that can be driven by the wheel 26 when it rotates one circle. In this embodiment, the length is set to 1CM. Of course, in other embodiments, the length of the driving shaft running in one circle and the distance between different blades in the first cutting knife 31 or the second cutting knife 32 can also be set to other values ​​according to needs.

[0040] like Figure 1 and Figure 4 As shown, in order to control the amount of medicinal materials in the feeding trough 1, a limit switch 11 is provided on the side of the feeding trough 1 close to the knife group. When the material push plate 21 runs to contact the limit switch 11, the motor 53 will be controlled to stop running, thereby making the material push plate 21 and the cutting knife 41 stop working, and then feeding can be carried out. In order to facilitate feeding, a reverse switch is also provided to make the motor 53 rotate in the reverse direction. When feeding is required, the reverse switch is pressed, and the material push plate 21 will move in the reverse direction.

[0041] In the embodiment 2 of the Chinese medicinal material dicing device of the present invention: for the setting of the guide plate, this embodiment proposes a new arrangement form. Different from the embodiment 1, the guide plate in this embodiment is provided with a gear hole of the same shape as the gear segment of the driving shaft, and the gear segment of the driving shaft is guided and matched with the guide plate. Of course, in other embodiments, the guide plate may not be provided, and the connection may be performed only through the fixing plate.

[0042] In Example 3 of the Chinese medicinal material dicing device of the present invention: Regarding the setting of the knife group, this embodiment proposes a new arrangement form. Different from Example 1, the knife group in this embodiment is a grid-shaped knife group in the same plane, that is, the first cutting knife and the second cutting knife are arranged flush.

[0043] In Example 4 of the Chinese medicinal material dicing device of the present invention: Regarding the setting of the knife group, this embodiment proposes a new arrangement form. Different from Example 1, in this embodiment, the first cutter and the second cutter are arranged at an angle, and the blades in the two knife groups are still perpendicular to each other to form a grid shape.

[0044] In Example 5 of the medicinal material dicing device of the present invention: With respect to the setting of the medicinal material dicing device, this embodiment proposes a new arrangement form. Different from Example 1, in this embodiment, the feed wheel and the knife wheel are still set as toothless gears, but the two are no longer installed on the same drive shaft, but are installed on different shafts through a transmission mechanism, and the different shafts produce a linkage effect. Of course, in other embodiments, a drive shaft is no longer set, but power sources for outputting power to the push plate transmission mechanism and the cutting knife transmission mechanism are respectively set, and the two power sources are independently controlled. Of course, in other embodiments, the two power sources can also be controlled by the same controller, so that when the material push plate moves, the cutting knife stops moving.

[0045] In Example 6 of the Chinese medicinal material dicing equipment of the present invention: Regarding the setting of the knife wheel, this embodiment proposes a new arrangement form. Different from Example 1, the knife wheel in this embodiment is a complete spur gear. When the knife wheel moves, the cutting knife moves accordingly. The switching time of the up and down strokes ensures that the size of the cut dices is uniform.

[0046] In the embodiment 7 of the Chinese medicinal material dicing device of the present invention: With respect to the setting of the cutting knife, this embodiment proposes a new arrangement form. Different from the embodiment 1, the cutting knife in this embodiment is set on the output shaft of the hydraulic cylinder and driven by the hydraulic cylinder to reciprocate. In other embodiments, the hydraulic cylinder can also be replaced by a pneumatic cylinder or an electric push rod.

[0047] In Example 8 of the Chinese medicinal material dicing device of the present invention: Regarding the setting of the dial-in wheel, this embodiment proposes a new arrangement form. Different from Example 1, the dial-in wheel in this embodiment is a complete spur gear. When the dial-in wheel moves, the material push plate moves accordingly, that is to say, the medicinal material is always in a state of being pushed.

[0048] In Example 9 of the Chinese medicinal material dicing device of the present invention: Regarding the setting of the material push plate, this embodiment proposes a new arrangement form. Different from Example 1, the material push plate in this embodiment is a circular plate, and its center part is connected to the driving shaft. As the driving shaft rotates, the material push plate also rotates. Of course, in other embodiments, a groove can also be set on the screw, and the material push plate can be set as two halves, which are stuck in the groove and rotated together.

[0049] In the embodiment 10 of the Chinese medicinal material dicing device of the present invention: for the setting of the driving shaft, this embodiment proposes a new arrangement form. Different from the embodiment 1, the driving shaft in this embodiment is the output shaft of the cylinder, which drives the material push plate to move linearly. Of course, in other embodiments, the cylinder can also be replaced by a hydraulic cylinder or an electric push rod.

[0050] In the embodiment 11 of the medicinal material dicing device of the present invention: With respect to the setting of the medicinal material dicing device, this embodiment proposes a new arrangement form. Different from the embodiment 1, the medicinal material dicing device in this embodiment only has a cutting knife transmission mechanism, and the material push plate is pushed manually. Of course, in other embodiments, the medicinal material dicing device only has a push plate transmission mechanism, and the cutting knife is operated manually. Of course, in other embodiments, no transmission mechanism may be provided, and all operations are performed manually.

[0051] In Example 12 of the Chinese medicinal material dicing device of the present invention: Regarding the setting of the knife group, this embodiment proposes a new arrangement form. Different from Example 1, the first cutter and the second cutter in this embodiment are no longer blades, but are composed of cutting lines arranged at intervals.

[0052] In Example 13 of the Chinese medicinal material dicing equipment of the present invention: Regarding the setting of the cam and the cam teeth, this embodiment proposes a new arrangement. Different from Example 1, in this embodiment, the cam teeth and the cam are respectively located on different axes, and the two axes are driven by a belt, so that the cam teeth and the cam rotate synchronously.
