Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, in particular to an anti-blocking Chinese medicine slice processing and conveying device. Background Art

[0002] Chinese herbal medicine slices are products made from Chinese medicinal materials after processing such as preparation, slicing, and drying, and can be directly used in clinical preparation or preparation production in traditional Chinese medicine.

[0003] At present, in the processing of Chinese herbal medicine slices, it is usually necessary to use a conveying device to transport the cut or sliced ​​Chinese medicinal materials from the previous process to the next process, such as transporting the Chinese medicinal materials after the slicing step to the drying step. During the conveying process, since the sliced ​​Chinese medicinal materials still have a certain water content, a long time is required for drying in the drying step. The drying equipment usually uses a conveyor belt and an oven to dry the Chinese medicinal materials. Since the Chinese medicinal materials are transported by the conveyor belt, the drying time in the oven cannot be guaranteed, which affects the drying efficiency of the Chinese medicinal materials. Although some conveying equipment in the prior art can be installed with a heating device to perform preliminary drying of the Chinese medicinal materials, since the Chinese medicinal materials are prone to accumulation during transportation, and the heating device is used for preliminary preheating and drying of the Chinese medicinal materials, its power is usually small, so the accumulated Chinese medicinal materials are not easily preheated and dried by the heating device, resulting in low efficiency of preliminary drying and preheating. Therefore, a conveying device is needed that can transport the sliced ​​Chinese medicinal materials and can perform efficient preliminary preheating and drying of the Chinese medicinal materials during the transportation process. Summary of the Invention

[0004] The purpose of the present invention is to provide a blocking-proof Chinese herbal medicine processing and conveying device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A blocking-proof Chinese herbal medicine processing and conveying device comprises a conveying cylinder with a feed port and a discharge port respectively provided at both ends, one end of the conveying cylinder being connected to a cover plate, and further comprising:

[0007] A conveying shaft is coaxially connected to the conveying cylinder and driven to rotate by a drive motor installed at the other end of the conveying cylinder;

[0008] Two fixed spiral augers are provided and are respectively fixedly sleeved on the axial ends of the conveying shaft;

[0009] A telescopic spiral auger is wrapped around the periphery of the conveying shaft and is located between the two fixed spiral augers, with both ends of the telescopic spiral auger being fixedly connected to the ends of the two fixed spiral augers respectively;

[0010] The telescopic component is provided on the blade wall surface in the middle part of the telescopic spiral auger, and when the conveying shaft rotates, the two ends of the telescopic spiral auger are respectively in compression and tension deformation states;

[0011] The heating component is arranged on the conveying cylinder and corresponds to the position of the telescopic spiral auger.

[0012] Through the above technical solution, the conveying shaft rotates, thereby driving the fixed spiral auger and the telescopic spiral auger to rotate, and thus the Chinese medicine tablets can be conveyed from the feed port to the discharge port, so that the Chinese medicine tablets can fall into the next process from the discharge port. In addition, when the conveying shaft rotates, the telescopic component will trigger the action, and the telescopic component will make the two sides of the telescopic spiral auger in compression and tension deformation states respectively. When in the tensioned state, the pitch of the tensioned part of the telescopic spiral auger increases, so that the Chinese medicine tablets in the tensioned telescopic spiral auger are relatively loose, so that the Chinese medicine tablets will not accumulate, and the Chinese medicine tablets will be evenly spread out, so that the heating component can fully and evenly preheat the Chinese medicine tablets, and the Chinese medicine tablets in the compressed part of the telescopic spiral auger will be squeezed by the blades of the telescopic spiral auger after heating, so that the residual moisture in the Chinese medicine tablets can be squeezed out, thereby improving the efficiency of preheating and drying, and thus the Chinese medicine tablets can achieve efficient preliminary drying and preheating during the conveying process.

[0013] Furthermore, the nominal diameters of the fixed spiral auger and the telescopic spiral auger are consistent, and are consistent with the inner diameter of the conveying cylinder.

[0014] Through the above technical solution, when the fixed spiral auger and the telescopic spiral auger are conveying Chinese medicine tablets, the Chinese medicine tablets will not enter between the periphery of the fixed spiral auger and the telescopic spiral auger and the inner wall of the conveying cylinder.

[0015] Furthermore, the inner diameter of the hollow portion in the middle of the telescopic spiral auger is larger than the outer diameter of the conveying shaft.

[0016] Through the above technical solution, the telescopic spiral auger has a certain buffer deformation space when it is telescopic or stretched.

[0017] Furthermore, the heating assembly includes a heat transfer chamber integrally formed and fixed to the conveying cylinder, a heat transfer pipe is wrapped around the periphery of the heat transfer chamber, and both ends of the heat transfer pipe are respectively connected to an external heat transfer oil conveying system.

[0018] Through the above technical solution, the external heat transfer oil delivery system delivers heat transfer oil of a certain temperature to the heat transfer pipe and flows in the heat transfer pipe. During the flow, the heat transfer oil produces a heating effect on the heat transfer chamber, thereby heating and drying the Chinese medicine tablets in the telescopic spiral auger.

[0019] Furthermore, the telescopic assembly includes an annular portion fixedly mounted in the heat conduction bin, the inner diameter of the annular portion is consistent with the inner diameter of the conveying cylinder, and the periphery of the telescopic spiral auger is in sliding contact with the inner wall of the annular portion, the blade wall in the middle part of the telescopic spiral auger is fixed with a sliding pin, and a sliding groove is provided on the inner wall of the annular portion, and the sliding groove is wavy in the circumferential direction, and the end of the sliding pin is engaged in the sliding groove and slides freely in the sliding groove.

[0020] Through the above technical solution, when the conveying shaft rotates, the sliding pin will slide in the sliding groove, and the two ends of the telescopic spiral auger can be alternately compressed and stretched, thereby achieving the spreading and squeezing of the Chinese medicine tablets.

[0021] Furthermore, a mounting cavity in the form of a blind hole is provided at one end of the sliding pin away from the conveying shaft, an air jet portion is rotatably mounted in the mounting cavity, the air jet portion is hollow inside and has an air jet opening on its periphery, and two air outlets are provided on the periphery of the sliding pin that penetrate the mounting cavity, and the two air outlets correspond to the axial ends of the conveying shaft respectively;

[0022] A connecting pipe is coaxially fixed to one end of the jet part facing the conveying shaft, and a connecting hole is provided in the sliding pin for the connecting pipe to rotate freely. The sliding pin is provided with an adjusting unit, and the adjusting unit is used to drive the jet part to rotate so that the jet port is alternately connected with the two air outlets. The conveying shaft is provided with a connecting unit, and the connecting unit is used to connect the connecting hole with an external compressed air delivery system.

[0023] Through the above technical solution, the external compressed air delivery system delivers compressed air to the connecting hole of the conveying shaft, and then enters the jet part through the connecting hole, and is ejected from the jet port of the jet part and the air outlet of the sliding pin in turn, thereby being able to produce a blowing and cleaning effect on the debris of the Chinese medicine tablets in the sliding groove, avoiding affecting the sliding of the sliding pin in the sliding groove. In addition, because the adjustment unit makes the jet port alternately connected with the two air outlets, the sliding pin can blow air in the front direction of the sliding process.

[0024] Furthermore, the connecting unit includes a gas delivery hole opened in the delivery shaft, a waist-shaped hole is opened on the periphery of the delivery shaft, the waist-shaped hole is connected to the gas delivery hole, and a sliding sleeve is slidably mounted on the periphery of the delivery shaft. The sliding sleeve is used to close the waist-shaped hole when the telescopic spiral auger is telescopically deformed. The end of the sliding pin is inserted into the sliding sleeve and freely passes through the waist-shaped hole. The gas delivery hole and the connecting hole are connected.

[0025] Through the above technical solution, the external compressed air delivery system delivers compressed air to the gas delivery hole of the delivery shaft, and the compressed air enters the connecting pipe through the gas delivery hole. In addition, a sliding sleeve is provided to seal the kidney-shaped hole to prevent fragments of Chinese medicine tablets from entering the delivery shaft through the kidney-shaped hole.

[0026] Furthermore, the adjustment unit includes a protrusion fixed to the wall of the sliding pin, a driving rod is passed through the protrusion for horizontal sliding, a rack portion is provided at one end of the driving rod passing through the sliding pin, and a gear portion meshing with the rack portion is opened at the periphery of the connecting tube.

[0027] Through the above technical solution, when the telescopic spiral auger is in a compressed state, the end of the driving rod will come into conflict with the blade surface of the telescopic spiral auger in the compressed state, and the driving rod will slide toward the protrusion, so that the rack part of the driving rod and the gear part are engaged and transmitted. During the engagement transmission, the connecting pipe can be driven to rotate, and when the connecting pipe rotates, the jet part will be driven to rotate.

[0028] Furthermore, an annular sleeve is fixedly embedded in the sliding pin, and the sliding pin is provided with an accommodating cavity for installing the annular sleeve. A volute spring is installed in the accommodating cavity. The volute spring is wrapped around the connecting pipe, and the inner and outer ring ends are respectively fixed to the connecting pipe and the wall of the annular sleeve.

[0029] Through the above technical solution, when the driving rod moves, the rack part and the gear part will engage and transmit, causing the connecting pipe to rotate. When the connecting pipe rotates, it will drive the jet part to rotate. When the jet part rotates, the scroll spring will be in a contracted state and accumulate elastic potential energy. Then, when the sliding pin moves in the opposite direction, the driving rod will be out of contact with the telescopic spiral auger blades, and the elastic potential energy accumulated in the scroll spring will be released, thereby driving the connecting pipe to rotate in the opposite direction, causing the jet part to rotate in the opposite direction, and causing the jet port to rotate until it is connected to the other air outlet.

[0030] Furthermore, a ball is rotatably embedded in one end of the driving rod away from the protruding portion.

[0031] Through the above technical solution, the ball contacts the telescopic spiral auger blade, so that the end of the driving rod does not cause friction and wear on the surface of the telescopic spiral auger blade.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In the present invention, the conveying shaft rotates, thereby driving the fixed spiral auger and the telescopic spiral auger to rotate, thereby being able to convey the Chinese medicine tablets from the feed port to the discharge port, so that the Chinese medicine tablets can fall into the next process from the discharge port. In addition, when the conveying shaft rotates, the telescopic component will trigger the action, and the telescopic component will make the two sides of the telescopic spiral auger be in compression and tension deformation states respectively. When in the tensioned state, the pitch of the tensioned part of the telescopic spiral auger increases, so that the Chinese medicine tablets in the tensioned telescopic spiral auger are relatively loose, so that the Chinese medicine tablets will not be piled up, and the Chinese medicine tablets will be evenly spread out, so that the heating component can fully and evenly preheat the Chinese medicine tablets, and the Chinese medicine tablets in the compressed part of the telescopic spiral auger will be squeezed by the blades of the telescopic spiral auger after being heated, so that the residual moisture in the Chinese medicine tablets can be squeezed out, thereby improving the efficiency of preheating and drying, and thus making the Chinese medicine tablets in the conveying process, able to achieve efficient preliminary drying and preheating;

[0034] 2. In the present invention, the external compressed air delivery system delivers compressed air to the connecting hole of the delivery shaft, and then enters the air jet section through the connecting hole and is ejected from the air jet port of the air jet section and the air outlet of the sliding pin in sequence, thereby producing a blowing and cleaning effect on the debris of the Chinese medicine tablets in the sliding groove, thereby avoiding affecting the sliding of the sliding pin in the sliding groove. In addition, because the adjustment unit alternately connects the air jet port with the two air outlets, the sliding pin can blow air in the front direction of the sliding process;

[0035] 3. In the present invention, when the driving rod moves, the rack portion and the gear portion engage and transmit, causing the connecting pipe to rotate. When the connecting pipe rotates, the jet portion is driven to rotate. When the jet portion rotates, the scroll spring is contracted and elastic potential energy is accumulated. Then, when the sliding pin moves in the opposite direction, the driving rod is disengaged from the telescopic spiral auger blade, and the elastic potential energy accumulated in the scroll spring is released, thereby driving the connecting pipe to rotate in the opposite direction, causing the jet portion to rotate in the opposite direction, and causing the jet port to rotate to be connected with the other air outlet.

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 making creative efforts are within the scope of protection of the present invention.

[0050] See also Figures 1-12The present invention provides a technical solution: a blocking-proof Chinese medicine slice processing and conveying device, comprising a conveying cylinder 5 with a feed port 2 and a discharge port 6 respectively provided at both ends, one end of the conveying cylinder 5 is connected to a cover plate 7, and a conveying shaft 10 is coaxially connected to the conveying cylinder 5, and a gas conveying hole in the form of a blind hole is coaxially opened in the conveying shaft 10, and a rotary joint (not shown in the figure) is provided on the surface of the cover plate 7, which is connected to an external compressed air conveying system through a pipeline, and the rotary joint is connected to the gas conveying hole, so that the compressed air conveying system can convey compressed air to the gas conveying hole through the rotary joint, and a driving motor 1 is installed at the end of the conveying cylinder 5 away from the cover plate 7, and the driving motor 1 is connected to the gas conveying hole through a coupling. The device and the reduction gear are connected to the end of the conveying shaft 10, so that the driving motor 1 can drive the conveying shaft 10 to rotate. The two axial ends of the conveying shaft 10 are respectively fixedly fitted with fixed spiral screw dragons 11, and the middle position of the conveying shaft 10 is fitted with a telescopic spiral screw dragon 9. The telescopic spiral screw dragon 9 can slide freely on the periphery of the conveying shaft 10. In addition, the telescopic spiral screw dragon 9 is located between the two fixed spiral screw dragons 11, and the two ends of the telescopic spiral screw dragon 9 are respectively fixed to the ends of the two fixed spiral screw dragons 11. The nominal diameters of the fixed spiral screw dragon 11 and the telescopic spiral screw dragon 9 are consistent, and are consistent with the inner diameter of the conveying cylinder 5. The inner diameter of the hollow part in the middle of the telescopic spiral screw dragon 9 is larger than the outer diameter of the conveying shaft 10;

[0051] A heat-conducting bin 3 is integrally fixed to the conveying cylinder 5, and a heat-conducting pipe 4 is wrapped around the periphery of the heat-conducting bin 3. Both ends of the heat-conducting pipe 4 are respectively connected to an external heat-conducting oil conveying system. The external heat-conducting oil conveying system conveys heat-conducting oil of a certain temperature to the heat-conducting pipe 4, and flows in the heat-conducting pipe 4. During the flow, the heat-conducting oil produces a heating effect on the heat-conducting bin 3, thereby heating and drying the Chinese medicine tablets in the telescopic spiral auger 9. An annular portion 8 is fixedly mounted in the heat-conducting bin 3, and the inner diameter of the annular portion 8 is consistent with the inner diameter of the conveying cylinder 5, and the periphery of the telescopic spiral auger 9 is in sliding contact with the inner wall of the annular portion 8.

When the sliding pin 13 slides toward the trough or peak of the sliding groove 26, the sliding pin 13 can drive the blades of the telescopic spiral auger 9 to move horizontally along the axial direction of the conveying shaft 10, thereby making the front part of the telescopic spiral auger 9 corresponding to the horizontal movement direction of the sliding pin 13 compressed, and the other side part is stretched. In this way, the telescopic spiral auger 9 in the compressed state produces an extrusion effect on the Chinese medicine tablets, and the telescopic spiral auger 9 in the stretched state can make the Chinese medicine tablets between the blades of the telescopic spiral auger 9 spread out, or in other words, the Chinese medicine tablets will not accumulate.

[0052] The end of the sliding pin 13 away from the conveying shaft 10 is provided with a blind hole-shaped mounting cavity, in which the air injection portion 15 (such as Figure 6 As shown), the jet portion 15 is hollow inside and has a jet port 20 on its periphery. Two air outlets 14 are provided on the periphery of the sliding pin 13, which pass through the mounting cavity. The two air outlets 14 correspond to the axial ends of the conveying shaft 10 respectively. A connecting pipe 22 is coaxially fixed to one end of the jet portion 15 facing the conveying shaft 10. A connecting hole for the connecting pipe 22 to rotate freely is provided in the sliding pin 13. The sliding pin 13 is provided with an adjusting unit, which is used to drive the jet portion 15 to rotate so that the jet port 20 is alternately connected to the two air outlets 14. A waist-shaped hole 25 is provided on the periphery of the conveying shaft 10 (as shown). Figure 11 As shown), the waist-shaped hole 25 is connected to the gas delivery hole, and the periphery of the delivery shaft 10 is slidably covered with a sliding sleeve 12. The sliding sleeve 12 is used to close the gap between the waist-shaped hole 25 and the sliding pin 13 when the telescopic spiral auger 9 is telescopically deformed. The end of the sliding pin 13 penetrates the sliding sleeve 12 and freely passes through the waist-shaped hole 25. The gas delivery hole and the communicating hole are interconnected. The outer diameter of the sliding sleeve 12 is consistent with the inner diameter of the hollow portion in the middle of the telescopic spiral auger 9;

[0053] The wall of the sliding pin 13 is fixed with a protrusion 19, and the protrusion 19 is penetrated by a driving rod 16 in a horizontal sliding manner. The end of the driving rod 16 that penetrates the sliding pin 13 is provided with a rack portion 18. The peripheral edge of the connecting pipe 22 is provided with a gear portion 23 that meshes with the rack portion 18. An annular sleeve 21 is fixedly embedded in the sliding pin 13, and the sliding pin 13 is provided with an accommodating cavity for the annular sleeve 21 to be installed. A volute spring 24 (such as Figure 8 As shown), the volute spring 24 is wrapped around the connecting pipe 22, and the inner and outer ring ends are respectively fixed to the connecting pipe 22 and the wall of the annular sleeve 21, and the end of the drive rod 16 away from the protrusion 19 is rotatably embedded with a ball 17.

[0054] Working principle of the present invention:

[0055] The sliced ​​Chinese medicine tablets containing a certain amount of water are put into the feed port 2, and the driving motor 1 is started. The driving motor 1 drives the conveying shaft 10 to rotate. When the conveying shaft 10 rotates, the two fixed spiral screws 11 are rotated, so that the fixed spiral screw 11 adjacent to the feed port 2 conveys the Chinese medicine tablets to the heat transfer bin 3, and then enters the right side of the telescopic spiral screw 9 (as shown in FIG. Figure 2The telescopic screw auger 9 is also in a rotating state, which enables the Chinese medicine tablet to move between the blades of the telescopic screw auger 9 toward the cover plate 7. The sliding pin 13 will slide in the sliding groove 26, that is, the sliding pin 13 will slide from a crest of the sliding groove 26 to an adjacent trough during the rotation of the conveying shaft 10, thereby driving the sliding pin 13 to generate horizontal movement along the axial direction of the conveying shaft 10. During the movement, since the two ends of the telescopic screw auger 9 are fixedly connected to the ends of the two fixed screw auger 11, the telescopic screw auger 9 will generate telescopic deformation;

[0056] Specifically, the telescopic spiral auger 9 is divided into two sections by the axis of the sliding pin 13, and the two sections are in a compressed state and a stretched state respectively. The Chinese medicine tablets between the blades of the telescopic spiral auger 9 in the stretched state are in a spread out state, while the Chinese medicine tablets between the blades of the telescopic spiral auger 9 in the compressed state are in an extruded state. At the same time, the external high-temperature heat transfer oil delivery system delivers the high-temperature heat transfer oil to the heat transfer pipe 4 and flows in the heat transfer pipe 4, that is, the heat transfer oil flows from one end of the heat transfer pipe 4 to the other end and flows back to the heat transfer oil delivery system, thereby being able to continuously heat the heat transfer chamber 3, while the blades of the telescopic spiral auger 9 in the stretched state The Chinese medicine tablets between the blades of the telescopic spiral auger 9 will be spread out, so that the Chinese medicine tablets will not pile up, so the preheating effect is better, and the Chinese medicine tablets between the blades of the telescopic spiral auger 9 in the compressed state will produce a squeezing effect on the Chinese medicine tablets after preheating, so that the residual moisture in the Chinese medicine tablets can be squeezed out to a certain extent. Since the sliding pin 13 can move back and forth horizontally, the compression and tension states of the blades on both sides of the telescopic spiral auger 9 are alternately changed, and then the Chinese medicine tablets can be squeezed and spread out reciprocally, reducing the accumulation of Chinese medicine tablets and affecting the preheating effect, and at the same time, the residual moisture in the Chinese medicine tablets can be squeezed to a certain extent;

[0057] During the sliding of the sliding pin 13 in the sliding groove 26, the external compressed air delivery system delivers the compressed air from the rotary joint to the gas delivery hole, and enters the communicating hole of the sliding pin 13, and then enters the inner cavity of the air jet portion 15, and then blows the compressed air into the sliding groove 26 from the air outlet 14, thereby blowing the Chinese medicine tablet debris in the sliding groove 26 in the direction of the horizontal movement of the sliding pin 13 in front of the sliding groove 26 to prevent interference with the sliding of the sliding pin 13 in the sliding groove 26. In addition, when the blades of the telescopic spiral auger 9 are compressed, the compressed air is blown into the sliding groove 26. In the retracted state, the ball 17 at the end of the drive rod 16 will contact the blade and move the drive rod 16 toward the protrusion 19, thereby causing the rack portion 18 of the drive rod 16 to engage with the gear portion 23 of the connecting pipe 22 for transmission, thereby driving the connecting pipe 22 to rotate. During the rotation process, the jet portion 15 also rotates synchronously. When the jet portion 15 rotates, the jet port 20 will be connected to the two air outlets 14 in turn, thereby allowing the compressed air to blow away the debris in the front direction of the horizontal movement direction of the sliding pin 13.
