Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine dispensing, and in particular to a Chinese medicine decoction piece separation and dispensing device. Background Art

[0002] In the production and adjustment process of Chinese herbal medicines, different types of herbal medicines need to be mixed into a prescription according to a certain weight. The traditional mixing method is mostly manual grabbing. In order to improve the efficiency and accuracy of herbal medicine adjustment and realize automated production, an automatic adjustment mechanism for Chinese herbal medicines is designed.

[0003] Due to the irregular shapes of Chinese herbal medicines, such as long strips, circles, and twisted shapes, the materials in the silo will experience bridging and entanglement. The bridging phenomenon refers to the overlapping of materials in the silo to form an arched structure, which hinders the free flow of materials and causes the materials to pile up and cannot fall naturally into the adjustment mechanism. The entanglement phenomenon causes the materials to clump together, and the clumped materials may be blocked between the silo outlet and the adjustment mechanism, hindering the normal operation of the adjustment mechanism. Summary of the invention

[0004] In order to solve the technical problems mentioned in the background technology, the present invention specifically provides a Chinese herbal medicine slice separation and adjustment device, comprising an adjustment mechanism and a separation mechanism installed at the outlet portion below the silo, wherein the separation mechanism is installed above the adjustment mechanism;

[0005] The separation mechanism comprises a plurality of separation arms capable of orbiting around the same central axis, wherein the plurality of separation arms can generate a travel difference in a downward and upward direction during the orbiting, so as to drive the material in the silo to move up and down to avoid bridging;

[0006] The plurality of separation arms can also rotate on their own during revolution, and stirring rods are installed on the circumferential surfaces of the separation arms to separate entangled materials, ensure smooth revolution and guide the materials out of the silo.

[0007] As a preferred solution of the present invention, the number of the separation arms is inversely proportional to the size of the material in the silo.

[0008] As a preferred solution of the present invention, a first separation shaft and a second separation shaft are symmetrically installed on both sides of the silo, and the ends of the multiple separation arms are respectively inserted into the circular holes set on the two separation shafts, so that the multiple separation arms can revolve around the axis of the separation shaft.

[0009] As a preferred solution of the present invention, the ends of the plurality of separation arms are all provided with self-rotating gears, and the self-rotating gears are meshed with an inner gear ring fixedly mounted on the silo, so that the separation arms can rotate when they revolve.

[0010] As a preferred solution of the present invention, the adjusting mechanism includes an adjusting screw and a motor, and the motor is connected to the adjusting screw through a coupling to drive the adjusting screw to rotate and feed;

[0011] The adjusting screw is connected to the first separation shaft through a transmission assembly.

[0012] As a preferred solution of the present invention, the transmission assembly includes a first transmission gear installed on the end of the adjusting screw and a second transmission gear installed on the end of the first separation shaft, and the first transmission gear is meshed with the second transmission gear.

[0013] As a preferred solution of the present invention, a plurality of groups of stirring rods are arranged on the circumferential surface of each separation arm along the axial direction of the separation arm, each group of stirring rods includes at least two stirring rods, and any two adjacent groups of stirring rods are staggered in the axial direction.

[0014] As a preferred solution of the present invention, the multiple groups of stirring rods on the same separation arm are staggered in the axial direction.

[0015] As a preferred solution of the present invention, the distances between the plurality of separation arms and the rotation center are the same, so that the up and down stroke difference is stable.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The Chinese herbal medicine slice separation and adjustment device of the present invention adds a separation mechanism above the adjustment mechanism. The stroke difference generated by the revolution of multiple separation arms can make the materials on both sides of the separation interface move up and down alternately. One material can be disturbed by the materials on the same side and the opposite side at the same time, preventing the materials from bridging, so that the materials can smoothly enter the adjustment mechanism.

[0018] The separation arm rotates while orbiting, and the stirring rod can sort the materials to prevent the clumping of materials from being blocked between the silo outlet and the adjusting mechanism, thereby ensuring the normal operation of the adjusting mechanism. The separation arm's rotation can also push away the materials in front of the separation arm's orbital movement direction, thereby reducing the probability of the separation arm getting stuck.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention specifically provides a Chinese medicine slice separation and adjustment device, comprising an adjustment mechanism 2 and a separation mechanism 3 installed at the outlet portion below a silo 1, wherein the separation mechanism 3 is installed above the adjustment mechanism 2, and the separation mechanism 3 can separate the material in the upper silo 1 and conduct it to the adjustment mechanism 2 below;

[0028] The separation mechanism 3 includes a plurality of separation arms 4 capable of orbiting around the same central axis. The plurality of separation arms 4 can generate a travel difference in the downward and upward directions when orbiting, so as to drive the material in the silo 1 to move up and down. The disturbance caused by the movement to the material can avoid material bridging.

[0029] The plurality of separation arms 4 can also rotate on their own while revolving, and stirring bars 5 are installed on the circumferential surfaces of the separation arms 4 to separate entangled materials and ensure smooth revolution of the separation arms 4 .

[0030] The principle of revolution to avoid bridging is as follows:

[0031] When the multiple separation arms 4 revolve around the center, the height of each rotating arm is constantly changing. When the height of the rotating arm increases, the material above will be pushed up. When it decreases, the material above will drop under the action of gravity. Therefore, the multiple separation arms 4 can generate a stroke difference in the downward and upward directions when revolving to drive the material in the silo 1 to move up and down. The disturbance caused by the movement to the material can avoid material bridging, so that the material can smoothly enter the adjustment mechanism 2;

[0032] And because there are multiple separation arms 4, when the multiple separation arms 4 revolve, there is a situation where the material on one separation arm 4 is pushed upward and the material on another separation arm 4 is lowered. There will also be a relative stroke difference between the materials on both sides of the lifting and separation interface, which will cause the materials on both sides of the interface to exert greater disturbance on each other and transmit it in the direction away from the interface, thereby enhancing the anti-bridging effect.

[0033] The principle of separating entangled materials by rotation and ensuring smooth revolution:

[0034] When the separation arm 4 rotates, the stirring rod 5 thereon rotates accordingly, and the material can be combed, separating the entangled material like a hair comb, so that the material can be evenly transferred to the adjusting mechanism 2 that falls below, avoiding the possibility that the clumped material may be blocked between the outlet of the silo 1 and the adjusting mechanism 2, thereby ensuring the normal operation of the adjusting mechanism 2.

[0035] When the separation arm 4 revolves, if the separation arm 4 does not rotate, the separation arm 4 is only equivalent to a push plate when pushing the material upward. However, since the separation arm 4 does not simply move up and down, but rotates, it will produce lateral displacement, and the lateral space of the silo 1 is filled with materials and is narrow, so the probability of the separation arm 4 being stuck is relatively high.

[0036] However, when the separation arm 4 can generate self-rotation while revolving, the self-rotation motion in conjunction with the stirring rod 5 can push away the material in front of the orbital motion trajectory of the separation arm 4, thereby reducing the probability of the separation arm 4 getting stuck.

[0037] In summary, the Chinese herbal medicine slice separation and adjustment device of the present invention adds a separation mechanism 3 above the adjustment mechanism 2, and the stroke difference generated by the revolution of multiple separation arms 4 can make the materials on both sides of the separation interface move up and down alternately, and one material can be disturbed by the materials on the same side and the opposite side at the same time, so as to prevent the materials from bridging and allow the materials to smoothly enter the adjustment mechanism 2;

[0038] The separation arm 4 rotates while orbiting, and the stirring rod 5 can comb the materials so that the materials can be evenly transferred to the adjustment mechanism 2 that falls below, avoiding the possibility that the clumped materials will be blocked between the outlet of the silo 1 and the adjustment mechanism 2, thereby ensuring the normal operation of the adjustment mechanism 2. In addition, the separation arm 4 can also rotate by itself to push away the materials located in front of the separation arm 4 in the direction of the orbital movement, thereby reducing the probability of the separation arm 4 getting stuck.

[0039] Furthermore, it is understandable that when the separation arm 4 is in orbit, the distance between it and the inner wall of the silo 1 is variable, which will cause uneven material delivery. Although the final material discharge weight is determined by the adjusting mechanism 2, in order to make the material fall into the adjusting mechanism 2 as evenly as possible and facilitate the uniform weight of each portion of material adjusted by the adjusting mechanism 2, the present invention limits the number of separation arms 4 as follows.

[0040] When multiple separation arms 4 are revolving, the maximum distance between the whole and the inner wall of the silo 1 is constantly changing. Taking the case where two separation arms 4 are set as an example, when the two separation arms 4 are in a vertical state (i.e., one separation arm 4 is on the top and the other separation arm 4 is on the bottom), the distance between the separation arm 4 and the silo 1 is greater than the distance between the separation arm 4 and the silo 1 when the two separation arms 4 are in a horizontal state (i.e., one separation arm 4 is on the left and the other separation arm 4 is on the right).

[0041] As the number of separation arms 4 increases, the maximum distance between the plurality of separation arms 4 as a whole and the silo 1 decreases. At the same time, as the number of separation arms 4 increases, the difference in up and down strokes generated during their revolution decreases.

[0042] On the other hand, the larger the size of the material, the greater the up and down stroke difference required to break the bridging effect; at the same time, the larger the size, the more difficult it is for a large number of materials to pass through the gap between the separation arm 4 and the silo 1.

[0043] On the contrary, the smaller the material size is, the smaller the up and down stroke difference required to break the bridging effect is, and the easier it is for a large number of materials to pass through the gap between the separation arm 4 and the silo 1.

[0044] Therefore, the number of separation arms 4 is inversely proportional to the size of the material in the silo 1, which can ensure that the material falls into the adjusting mechanism 2 as evenly as possible while eliminating the bridging effect (evenly means that the weight of the material falling into the adjusting mechanism 2 per unit time is the same).

[0045] Furthermore, a first separation shaft 6 and a second separation shaft 7 are symmetrically installed on both sides of the silo 1, and the ends of the plurality of separation arms 4 are respectively inserted into the circular holes 8 provided on the two separation shafts, and the separation arms 4 can rotate in the circular holes 8. The circular holes 8 are located on the side of the axis of the separation shafts, and when the two separation shafts rotate, the separation arms 4 will be driven to revolve around the axis, so that the plurality of separation arms 4 can revolve around the axis of the separation shafts.

[0046] Furthermore, the ends of the plurality of separation arms 4 are all provided with self-rotating gears 9 , which mesh with an inner gear ring 10 fixedly mounted on the silo 1 , so that the separation arms 4 can self-rotate when they revolve. Figure 1 , Figure 3 and Figure 4 It is a schematic diagram when two separation arms 4 are provided.

[0047] By positioning and matching the self-rotating gear 9 and the inner gear ring 10, only one driving force is applied to the separation shaft to simultaneously realize the revolution and self-rotation of the separation arm 4. It should be noted that the self-rotating gear 9 and the inner gear ring 10 are both installed inside the silo 1.

[0048] Furthermore, the adjusting mechanism 2 includes an adjusting screw 11 and a motor 12, and the motor 12 is connected to the adjusting screw 11 through a coupling 13 to drive the adjusting screw 11 to rotate and feed the material. When the separation mechanism 3 makes the amount of material falling into the adjusting screw 11 per unit time substantially equal, the adjusting screw 11 rotates the same number of times and the output of the material can be substantially equal.

[0049] The adjusting screw 11 is connected to the first separation shaft 6 through a transmission assembly, so that the adjusting screw 11 and the separation mechanism 3 keep running synchronously, which just satisfies the time consistency of the separation and adjustment work.

[0050] At the same time, a motor 12 outputs power to drive the adjusting screw 11 to rotate, the separation arm 4 to revolve, and the separation arm 4 to rotate.

[0051] Further, the transmission assembly includes a first transmission gear 14 installed at the end of the adjusting screw 11 and a second transmission gear 15 installed at the end of the first separation shaft 6 , and the first transmission gear 14 is meshed with the second transmission gear 15 .

[0052] Furthermore, a plurality of groups of stirring rods 5 are arranged on the circumferential surface of each separation arm 4 along the axial direction of the separation arm 4 , each group of stirring rods 5 includes at least two stirring rods 5 , and any two adjacent groups of stirring rods 5 are staggered in the axial direction.

[0053] By staggering the stirring rods 5, each separation arm 4 is regarded as a whole, which can increase the coverage of the stirring rods to comb out entangled materials on the one hand, and on the other hand, can expand the spacing between the stirring rods in the same group, reduce the resistance of each group of stirring rods when rotating to comb out materials, and reduce the resistance of the materials to the stirring rods when the separation arm 4 revolves. Due to the staggered setting, even if the spacing is expanded, the entangled materials will not be missed.

[0054] Furthermore, the multiple groups of stirring rods 5 on the same separation arm 4 are all staggered in the axial direction, further increasing the adjustable stirring rod spacing.

[0055] Furthermore, the distances between the plurality of separation arms 4 and the rotation center are the same, so that the up and down stroke difference is stable.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
