Description

Technical Field

[0002] Traditional Chinese medicine decoction pieces refer to traditional Chinese medicines that can be directly used in clinical practice of traditional Chinese medicine after being processed according to the theory of traditional Chinese medicine and the methods of traditional Chinese medicine processing. There are various types of traditional Chinese medicine decoction pieces, such as extremely thin slices, thin slices, thick slices, oblique slices, straight slices, segments (chewed, jointed), filaments, blocks, etc., and their thickness and shape are processed according to the characteristics and needs of the medicinal materials.

[0003] In the process of traditional Chinese medicine decoction pieces processing, currently, a conveyor belt is usually used to transport the processed traditional Chinese medicine decoction pieces. In the actual transportation process, the conveyor belt used for traditional Chinese medicine decoction pieces is usually of an exposed structure, so it has no dust-proof effect, and the dust in the traditional Chinese medicine decoction pieces will volatilize when the decoction pieces contact and separate from the conveyor belt. For the transportation of traditional Chinese medicine decoction pieces through a spiral conveyor belt, when a blockage occurs inside the spiral conveyor belt, it is necessary to stop the machine for maintenance. For the conveying equipment with a dust-proof structure arranged outside the spiral conveyor belt, the dust-proof structure also needs to be removed during maintenance, so that the existing traditional Chinese medicine decoction pieces have poor dust-proof and anti-blocking effects during processing, and it is not easy to repair when blocked. Summary of the Invention

When determining the blockage position of the spiral blade through the resistance module, the inner shaft is driven to rotate so that the through hole at the blockage position communicates with the air hole, and at this time, the air hole and the through hole at the non-blockage position are in a non-communicating state. By supplying air to the inner shaft to increase the gas pressure inside the inner shaft, the traditional Chinese medicine decoction pieces in the blocked area are impacted under the action of the gas pressure.

[0055] The following describes the implementation manners of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0056] Please refer to Figures 1 to 13 . It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions under which the present invention can be implemented. Therefore, they do not have technical substantial significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention.

[0057] Please refer to Figures 1 to 7 , the present invention discloses a conveying device with dust and blockage prevention functions for traditional Chinese medicine decoction pieces processing, which can be used to improve the poor dust and blockage prevention effects of existing traditional Chinese medicine decoction pieces during processing, and the problem that it is not easy to repair when blocked. Specifically, the conveying device with dust and blockage prevention functions for traditional Chinese medicine decoction pieces processing includes a base plate 10, a conveying box 100, a conveying mechanism 110, a feeding mechanism, and a controller. Among them, the conveying mechanism 110 is arranged in the conveying box 100 and is used to convey traditional Chinese medicine decoction pieces. The conveying box 100 is arranged on the base plate 10, and a plurality of height-adjustable feet are also connected to the base plate 10. The height of the feet is adjusted to improve the stability of the equipment during the transportation of traditional Chinese medicine decoction pieces.

[0058] It should be noted that one end of the conveying box 100 is provided with a feeding port, and the other end is provided with a discharging port. The feeding mechanism is arranged at the feeding port. Traditional Chinese medicine decoction pieces enter the conveying box 100 through the feeding mechanism and are discharged from the discharging port of the conveying box 100 after being conveyed by the conveying mechanism 110.

[0059] Please refer to Figures 1 to 7, in one embodiment, the conveying mechanism 110 is disposed within the conveying box 100 and includes a main shaft 112, a spiral blade 111, an inner shaft 130, a first power mechanism, and a second power mechanism. Among them, the main shaft 112 is rotatably connected to the conveying box 100. The main shaft 112 is hollow, and a plurality of through holes 1101 are provided on the main shaft 112. The spiral blade 111 is fixedly connected to the main shaft 112, and a resistance module is provided within the spiral blade 111. The resistance module may allow the use of a plurality of piezoresistive pressure sensors, and the piezoresistive pressure sensors are electrically connected to the controller. The piezoresistive pressure sensors are distributed on the surface of the spiral blade 111. When the spiral blade 111 becomes blocked, the pressure of the piezoresistive pressure sensors on the surface layer of the spiral blade 111 will change. It is allowed to preset a pressure threshold. When the pressure of the piezoresistive pressure sensor is higher than this pressure threshold, it is determined that the spiral blade 111 at the position of the piezoresistive pressure sensor is blocked.

[0060] Furthermore, the inner shaft 130 is rotatably disposed within the main shaft 112. One end of the main shaft 112 is closed, and the other end is connected to a gas source. A plurality of air holes 131 are provided on the inner shaft 130, and the air holes 131 are in communication with the gas source. For example, in one embodiment, it is allowed to connect an air supply pipe 40 to the inner shaft 130, and an air pump is connected to the air supply pipe 40. The air pump supplies air into the inner shaft 130 through the air supply pipe 40 to increase the gas pressure within the inner shaft 130.

[0061] The plurality of air holes 131 are arranged in a spiral shape on the inner shaft 130, and when the inner shaft 130 and the main shaft 112 rotate relative to each other, the air holes 131 are intermittently in communication with their corresponding through holes 1101. It should be noted that the plurality of through holes 1101 on the main shaft 112 are linearly arranged, and at least one through hole 1101 is provided between adjacent leaf surfaces of the spiral blade 111. The plurality of air holes 131 located on the inner shaft 130 are spiral-shaped, and when the inner shaft 130 rotates relative to the main shaft 112, it is selectively possible to achieve the communication between the air holes 131 on the inner shaft 130 and the through holes 1101 on the main shaft 112. When the controller determines the blockage position of the spiral blade 111 through the resistance module, it drives the inner shaft 130 to rotate so that the through hole 1101 at the blockage position is in communication with the air hole 131. At this time, the air holes 131 at the non-blockage positions are not in communication with the through holes 1101. Therefore, by supplying air to the inner shaft 130 to increase the gas pressure within the inner shaft 130, the traditional Chinese medicine pieces within the blocked area are impacted under the action of the gas pressure. It is possible to achieve the automatic positioning of the blockage position of the spiral blade 111 and automatic blockage removal, improve the transportation efficiency of the traditional Chinese medicine pieces during the transportation process, and also avoid shutting down the conveying equipment for maintenance.

[0062] Furthermore, the first power mechanism is drivingly connected to the main shaft 112, and the second power mechanism is drivingly connected to the inner shaft 130.

[0063] Specifically, the first power mechanism includes a first motor 20 and a transmission case 120. The first motor 20 is electrically connected to the controller, and the transmission case 120 is fixedly connected to the substrate 10. At the same time, a transmission structure is provided inside the transmission case 120, and the transmission structure can be determined according to actual needs. For example, the transmission structure can be a structure where multiple gears mesh with each other, or a belt drive structure. However, it is not limited thereto and can be determined according to actual needs. It should be noted that the transmission case 120 includes an input end and two output ends. The rotating shaft of the first motor 20 is in transmission connection with the input end, and one output end is in transmission connection with the main shaft 112. Therefore, it is possible to drive the main shaft 112 to rotate through the first motor 20.

[0064] The second power mechanism includes a second motor 30, which is electrically connected to the controller. The rotating shaft of the second motor 30 is in transmission connection with the inner shaft 130. Therefore, it is possible to drive the inner shaft 130 to rotate through the second motor 30.

[0065] It can be understood that the controller is electrically connected to the resistance module, the first power mechanism, and the second power mechanism respectively. Therefore, the controller is used to drive the states of the various components of the device during actual use. Among them, a resistance - position - angle look - up table can be preset. The resistance - position - angle look - up table represents the corresponding relationship among the resistance value of the resistance module, the blockage position of the spiral blade 111, and the rotation angle required for the inner shaft 130. When a blockage occurs in the spiral blade, the resistance value of the resistance module in the spiral blade increases. Based on the resistance - position - angle look - up table, the blockage position of the spiral blade 111 and the rotation angle of the inner shaft 130 are obtained. The controller drives the inner shaft 130 to rotate through the second power mechanism, so that the air holes 131 on the inner shaft 130 are communicated with the through holes 1101 on the main shaft 112 in the blockage area, and the pressure inside the inner shaft 130 is increased by the air source. By supplying air to the inner shaft 130, the gas pressure inside the inner shaft 130 is increased, and under the action of the gas pressure, the traditional Chinese medicine pieces in the blockage area are impacted and opened.

[0066] Among them, since the main shaft 112 is in a rotating state. Therefore, in one embodiment, a first positioning terminal 132 is provided on the main shaft 112, and a second positioning terminal 1121 is provided on the inner shaft 130. A communication connection is provided between the first positioning terminal 132 and the second positioning terminal 1121. When a blockage occurs in the spiral blade 111 on the main shaft 112, first, the inner shaft 130 can be driven to rotate so that the first positioning terminal 132 and the second positioning terminal 1121 are matched. When the first positioning terminal 132 and the second positioning terminal 1121 are matched with each other, the angle of the inner shaft 130 can be adjusted through the resistance - position - angle look - up table.

[0067] Please refer toFigures 1 to 13 In one embodiment, the feeding mechanism is connected to the conveying box 100 and is located at the feeding port of the conveying box 100. Specifically, the feeding mechanism includes a feed box 200, two retractable guide plates 210 and a transmission mechanism. Among them, the feed box 200 is fixedly connected to the conveying box 100, and a discharge box 260 is slidably arranged in the feed box 200. One end of the guide plate 210 is pivotally connected to the feed box 200, and the other end is pivotally connected to the discharge box 260. For example, the guide plate 210 may be allowed to include a first connecting plate 211 and a second connecting plate 212, and the first connecting plate 211 and the second connecting plate 212 are slidably connected. Among them, one end of the first connecting plate 211 is pivotally connected to the feed box 200, and one end of the second connecting plate 212 is pivotally connected to the discharge box 260.

[0068] Therefore, when the lower material box 260 slides in the inlet box 200, the retractable guide plate 210 allows the Chinese herbal medicine pieces to enter the inlet box 200 through the guide plate 210, and then enter the inlet of the transport box through the inlet box 200. The transmission mechanism is connected to the lower material box 260, and is used to drive the lower material box 260 to reciprocate in the inlet box 200.

[0069] It is understandable that when the lower feed box 260 is in the process of reciprocating movement, the Chinese medicinal pieces can be uniformly fed into the feed inlet, thereby preventing the Chinese medicinal pieces from piling up in the feed inlet and reducing the risk of blockage during the transportation of the Chinese medicinal pieces.

[0070] Further, the transmission mechanism includes a transmission disc 230, a driving rod 240 and a driving disc 121. The transmission disc 230 is rotatably connected to one side of the feed box 200, and the transmission disc 230 is transmission-connected to the first power mechanism. Specifically, an output end is provided on the transmission box 120 of the first power mechanism, and the output end is fixedly connected to the driving disc 121. Therefore, when the first motor 20 drives the main shaft 112 to rotate, it can synchronously drive the driving disc 121 to rotate.

[0071] It is understandable that the driving disc 121 is connected to the transmission disc 230. For example, a belt may be provided between the driving disc 121 and the transmission disc 230 to achieve synchronous rotation between the driving disc 121 and the transmission disc 230 through the belt.

[0072] Specifically, a limiting groove 241 is formed in the driving rod 240, and a limiting block 242 is slidably arranged in the limiting groove 241, and the limiting block 242 is fixedly connected to the transmission disc 230. Among them, the driving rod 240 is slidably connected to the feeding box 200, and the blanking box 260 is fixedly connected to the driving rod 240. Specifically, a telescopic assembly 220 may be provided on the feeding box 200, and the driving rod 240 is connected to the telescopic assembly 220. For example, in an embodiment, the telescopic assembly 220 includes a base 221, a first connecting rod 222 and a second connecting rod 223. Among them, the base 221 is fixedly connected to the feeding box 200, and the first connecting rod 222 is fixedly connected to the base 221. The second connecting rod 223 is slidably connected to the first connecting rod 222, and the driving rod 240 is fixedly connected to the second connecting rod 223. Among them, the sliding direction between the first connecting rod 222 and the second connecting rod 223 is perpendicular to the sliding direction of the limiting block 242 in the limiting groove 241.

[0073] In order to improve the sliding effect of the blanking box 260 during the sliding process, a sliding groove 250 may be provided on the feeding box 200, which can effectively improve the stability of the blanking box 260 during the sliding process.

[0074] In summary, the present invention discloses a conveying device with dust-proof and anti-blocking functions for traditional Chinese medicine decoction pieces processing. When the resistance module determines the blocking position of the spiral blade 111, the inner shaft 130 is driven to rotate so that the through hole 1101 at the blocking position is communicated with the air hole 131. At this time, the air hole 131 at the non-blocking position and the through hole 1101 are in a non-communicated state. By supplying air to the inner shaft 130, the gas pressure inside the inner shaft 130 is increased, and the traditional Chinese medicine decoction pieces in the blocked area are impacted under the action of the gas pressure. It can realize the automatic positioning of the blocking position of the spiral blade 111 and automatic blockage removal, improve the transportation efficiency of traditional Chinese medicine decoction pieces during the transportation process, and avoid downtime maintenance of the conveying equipment. At the same time, by arranging a reciprocating blanking box 260 at the feeding port, the traditional Chinese medicine decoction pieces can enter the feeding port evenly. Avoid the accumulation of traditional Chinese medicine decoction pieces in the feeding port, thereby reducing the risk of blockage during the transportation of traditional Chinese medicine decoction pieces.

[0075] Therefore, it can effectively improve the poor dust-proof and anti-blocking effects of the existing traditional Chinese medicine decoction pieces during the processing process and the problem that it is not easy to repair when blocked. Therefore, the present invention effectively overcomes some practical problems in the prior art and thus has high utilization value and practical significance.

[0076] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
