Description

Technical Field

[0001] The invention relates to the technical field of Chinese herbal medicine slice processing, and in particular to a conveying device with dust and blockage prevention functions for Chinese herbal medicine slice processing. Background Art

[0002] Chinese herbal medicine slices refer to Chinese herbal medicines that have been processed according to the theory of traditional Chinese medicine and the processing methods of traditional Chinese medicine and can be directly used in clinical Chinese medicine. There are many types of Chinese herbal medicine slices, such as very thin slices, thin slices, thick slices, oblique slices, straight slices, segments (twisted, knotted), threads, blocks, etc. Their thickness and shape are processed according to the characteristics and needs of the medicinal materials.

[0003] In the processing of Chinese herbal medicine slices, conveyor belts are currently usually used to transport the sliced ​​Chinese herbal medicine slices. In the actual transportation process, the conveyor belts used for Chinese herbal medicine slices are usually exposed structures, so they have no dust-proof effect. The dust in the Chinese herbal medicine slices will evaporate when the slices and the conveyor belt come into contact and separate. For the transportation of Chinese herbal medicine slices by spiral conveyor belts, when blockage occurs in the spiral conveyor belt, it is necessary to shut down for maintenance. For conveying equipment with a dust-proof structure on the outside of the spiral conveyor belt, the dust-proof structure needs to be removed when it is shut down for maintenance, so that the existing Chinese herbal medicine slices have poor dust and blockage prevention effects during the processing process, and are not easy to repair when blocked. Summary of the invention

[0004] In view of the above shortcomings of the prior art, the purpose of the present invention is to disclose a conveying device with dust and blockage prevention functions for processing Chinese herbal medicines, so as to improve the problems of poor dust and blockage prevention effects during the processing of existing Chinese herbal medicines, as well as the difficulty in maintenance when blocked.

When blockage occurs in the spiral blade, the resistance of the resistor module in the spiral blade increases, and the blockage position of the spiral blade and the rotation angle of the inner shaft are obtained based on the resistance-position-angle comparison table; the controller drives the inner shaft to rotate through the second power mechanism, so that the air holes on the inner shaft are connected with the through holes on the main shaft in the blockage area, and the pressure in the inner shaft is increased through the air source.

[0006] In one embodiment of the present invention, the resistance module is a plurality of piezoresistive pressure sensors, which are distributed on the blade surface of the spiral blade, and the piezoresistive pressure sensors are electrically connected to the controller.

[0007] In one embodiment of the present invention, The first power mechanism comprises: A first motor, electrically connected to the controller; A transmission box including an input end and two output ends; Wherein, the rotating shaft of the first motor is transmission-connected to the input end, one of the output ends is transmission-connected to the main shaft, and a driving disk is fixedly connected to the other output end.

[0008] In one embodiment of the present invention, the second power mechanism includes a second motor which is electrically connected to the controller, and a rotating shaft of the second motor is transmission-connected to the inner shaft.

[0009] In one embodiment of the present invention, the feeding mechanism comprises: A feed box is fixedly connected to the conveying box, and a feed box is slidably arranged inside the feed box; two retractable material guide plates, one end of each material guide plate being pivotally connected to the feed box and the other end of each material guide plate being pivotally connected to the discharge box; and The transmission mechanism is connected to the unloading box and is used to drive the unloading box to move back and forth in the loading box.

[0010] In one embodiment of the present invention, the material guide plate includes a first connecting plate and a second connecting plate, and the first connecting plate and the second connecting plate are slidably connected; Among them, one end of the first connecting plate is pivotally connected to the feeding box, and one end of the second connecting plate is pivotally connected to the unloading box.

[0011] In one embodiment of the present invention, the transmission mechanism comprises: A transmission disc, rotatably connected to one side of the feed box, and the transmission disc is transmission-connected to the first power mechanism; A driving rod is provided with a limiting groove, a limiting block is slidably arranged in the limiting groove, and the limiting block is fixedly connected to the transmission disk; wherein the driving rod is slidably connected to the feeding box, and the unloading box is fixedly connected to the driving rod.

[0014] In one aspect of the present invention, a base plate is further included, and the conveying box is located on the base plate.

[0015] In summary, the present invention discloses a conveying device with dust and blockage prevention functions for processing Chinese herbal medicine slices. When the blocking position of the spiral blade is determined by the resistance module, the inner shaft is driven to rotate so that the through hole at the blocking position is connected to the pore, and the pore at the non-blocking position is not connected to the through hole. By supplying air to the inner shaft to increase the gas pressure in the inner shaft, the Chinese herbal medicine slices in the blocked area are impacted and opened under the action of the gas pressure. Automatic positioning of the blocking position of the spiral blade and automatic unblocking can be achieved, thereby improving the transportation efficiency of the Chinese herbal medicine slices during transportation and avoiding shutdown of the conveying equipment for maintenance.

[0016] By providing a reciprocating feed box at the feed inlet, the Chinese herbal medicine pieces can be uniformly fed into the feed inlet, thereby preventing the Chinese herbal medicine pieces from piling up in the feed inlet, thereby reducing the risk of blockage of the Chinese herbal medicine pieces during transportation. The existing Chinese herbal medicine pieces can effectively improve the poor dust and blockage prevention effects during processing, as well as the problem of being difficult to repair when blocked.

DETAILED DESCRIPTION

[0020] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] See also Figures 1 to 13 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which the present invention can be implemented. Therefore, they have no substantive technical significance. Any modification of the structure, change in the proportion relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0022] See also Figures 1 to 7 The present invention discloses a conveying device with dust and blockage prevention functions for processing Chinese herbal medicines, which can be used to improve the poor dust and blockage prevention effects of existing Chinese herbal medicines during processing, as well as the problem of being difficult to repair when blocked. Specifically, the conveying device with dust and blockage prevention functions for processing Chinese herbal medicines 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, which is used to convey the Chinese herbal medicines. The conveying box 100 is arranged on the base plate 10, and a plurality of height-adjustable foot supports are also connected to the base plate 10. The height of the foot supports is adjusted to improve the stability of the equipment during the transportation of the Chinese herbal medicines.

[0023] It should be noted that a feed port is provided at one end of the conveying box 100, and a discharge port is provided at the other end. The feed mechanism is provided at the feed port, and the Chinese herbal medicine pieces enter the conveying box 100 through the feed mechanism, and are transported by the conveying mechanism 110 and discharged from the conveying box 100 through the discharge port.

[0024] See also Figures 1 to 7 In one embodiment, the conveying mechanism 110 is arranged in 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 arranged on the main shaft 112. The spiral blade 111 is fixedly connected to the main shaft 112, and a resistance module is arranged in the spiral blade 111. The resistance module allows the use of multiple piezoresistive pressure sensors, and the piezoresistive pressure sensors are electrically connected to the controller. The piezoresistive pressure sensors are distributed on the blade surface of the spiral blade 111. When the spiral blade 111 is blocked, the pressure of the piezoresistive pressure sensor on the surface 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 the pressure threshold, it is determined that the spiral blade 111 at the position of the piezoresistive pressure sensor is blocked.

[0025] Further, the inner shaft 130 is rotatably disposed in the main shaft 112, one end of the main shaft 112 is closed, and the other end is connected to the gas source. The inner shaft 130 is provided with a plurality of air holes 131, and the air holes 131 are connected to the gas source. For example, in one embodiment, it is allowed to connect the air supply pipe 40 to the inner shaft 130, and the air supply pipe 40 is connected to the air pump. The air pump supplies air to the inner shaft 130 through the air supply pipe 40 to increase the gas pressure in the inner shaft 130.

[0026] A plurality of pores 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 pores 131 and the corresponding through holes 1101 are intermittently connected. It should be noted that the plurality of through holes 1101 on the main shaft 112 are arranged linearly, and at least one through hole 1101 is arranged between adjacent blade surfaces of the spiral blade 111. The plurality of pores 131 on the inner shaft 130 are spirally arranged, and when the inner shaft 130 rotates relative to the main shaft 112, the pores 131 on the inner shaft 130 can be selectively connected with the through holes 1101 on the main shaft 112. When the controller determines the blocked position of the spiral blade 111 through the resistance module, it drives the inner shaft 130 to rotate so that the through holes 1101 at the blocked position are connected with the pores 131. At this time, the pores 131 at the non-blocked position are in a non-connected state with the through holes 1101. Therefore, by supplying air to the inner shaft 130 to increase the gas pressure in the inner shaft 130, the Chinese medicinal pieces in the blocked area are impacted and opened under the action of the gas pressure. Automatic positioning of the blocked position of the spiral blade 111 and automatic unblocking can be achieved, thereby improving the transportation efficiency of the Chinese medicinal pieces during transportation and avoiding the shutdown of the conveying equipment for maintenance.

[0027] 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 .

[0028] Specifically, the first power mechanism includes a first motor 20 and a transmission box 120. The first motor 20 is electrically connected to the controller, and the transmission box 120 is fixedly connected to the substrate 10. At the same time, a transmission structure is arranged in the transmission box 120, and the transmission structure can be determined according to actual needs. For example, the transmission structure can be a structure in which multiple gears are meshed with each other, or a belt transmission structure. However, it is not limited to this and can be determined according to actual needs. It should be noted that the transmission box 120 includes an input end and two output ends, wherein the rotating shaft of the first motor 20 is transmission-connected to the input end, and an output end is transmission-connected to the main shaft 112. Therefore, it is allowed to drive the main shaft 112 to rotate by the first motor 20.

[0029] The second power mechanism includes a second motor 30, which is electrically connected to the controller, and the rotation shaft of the second motor 30 is transmission-connected to the inner shaft 130. Therefore, the inner shaft 130 can be driven to rotate by the second motor 30.

[0030] 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, it is allowed to preset a resistance value-position-angle comparison table, which represents the corresponding relationship between the resistance value of the resistance module, the blocking position of the spiral blade 111, and the angle required to rotate the inner shaft 130. When a blockage occurs in the spiral blade, the resistance value of the resistance module in the spiral blade increases, and the blocking position of the spiral blade 111 and the rotation angle of the inner shaft 130 are obtained based on the resistance value-position-angle comparison table; the controller drives the inner shaft 130 to rotate through the second power mechanism, so that the air hole 131 on the inner shaft 130 is connected with the through hole 1101 on the main shaft 112 in the blocked area, and the pressure in the inner shaft 130 is increased by the gas source. By supplying air to the inner shaft 130, the gas pressure in the inner shaft 130 is increased, and the Chinese herbal medicine pieces in the blocked area are impacted and opened under the action of the gas pressure.

[0031] 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 the spiral blade 111 on the main shaft 112 is blocked, the inner shaft 130 can be driven to rotate first so that the first positioning terminal 132 and the second positioning terminal 1121 match. When the first positioning terminal 132 and the second positioning terminal 1121 match each other, it is allowed to adjust the angle of the inner shaft 130 through the resistance value-position-angle comparison table.

[0032] See also Figures 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] Specifically, a limiting groove 241 is provided on the driving rod 240, a limiting block 242 is slidably provided in the limiting groove 241, and the limiting block 242 is fixedly connected to the transmission disc 230. The driving rod 240 is slidably connected to the feed box 200, and the unloading box 260 is fixedly connected to the driving rod 240. Specifically, the feed box 200 may be provided with a telescopic assembly 220, and the driving rod 240 is connected to the telescopic assembly 220. For example, in one embodiment, the telescopic assembly 220 includes a base 221, a first connecting rod 222, and a second connecting rod 223. The base 221 is fixedly connected to the feed 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. 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 .

[0038] In order to improve the sliding effect of the lower material box 260 during the sliding process, it is allowed to provide a slide groove 250 on the input box 200, which can effectively improve the stability of the lower material box 260 during the sliding process.

[0039] In summary, the present invention discloses a conveying device with dust and anti-blocking functions for processing Chinese herbal medicine slices. When the blocking position of the spiral blade 111 is determined by the resistance module, the inner shaft 130 is driven to rotate so that the through hole 1101 at the blocking position is connected to the air hole 131, and the air hole 131 at the non-blocking position is in a non-connected state with the through hole 1101. By supplying air to the inner shaft 130, the gas pressure in the inner shaft 130 is increased, and the Chinese herbal medicine slices in the blocked area are impacted and opened under the action of the gas pressure. Automatic positioning of the blocking position of the spiral blade 111 and automatic unblocking can be achieved, thereby improving the transportation efficiency of the Chinese herbal medicine slices during transportation and avoiding the shutdown of the conveying equipment for maintenance. At the same time, by providing a reciprocating unloading box 260 at the feed inlet, the Chinese herbal medicine slices can be uniformly entered into the feed inlet. The accumulation of Chinese herbal medicine slices in the feed inlet is avoided, thereby reducing the risk of blockage of the Chinese herbal medicine slices during transportation.

[0040] Therefore, the existing Chinese herbal medicine slices can effectively improve the poor dust and blockage prevention effect during the processing, and the problem of being difficult to repair when blocked. Therefore, the present invention effectively overcomes some practical problems in the prior art and has high utilization value and use significance.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
