Description

Technical Field

[0001] The invention relates to the technical field of medicinal material processing, in particular to a medicinal material drying device for pharmaceutical profession. Background Art

[0002] Medicinal material drying generally refers to the drying step of Chinese medicinal materials. It is a processing procedure for dehydrating Chinese medicinal materials and maintaining their original ingredients and medicinal properties. Drying is to allow them to be preserved for a long time. Depending on the specific Chinese medicinal materials, the drying process is different. Some Chinese medicinal materials will lose their medicinal effects after exceeding a certain temperature, so it is very important to control the temperature during the drying process.

[0003] The utility model patent with authorization announcement number CN217737762U discloses a medicinal material drying device for Chinese medicine professionals, including a box frame, a motor, a rotating shaft and a placement box. The middle part of the top of the box frame is connected to the motor by bolts, and the transmission output end of the motor is installed with the rotating shaft. In the above patent, the Chinese medicinal materials to be dried are placed in the placement box and the placement box is closed. Then, only the box door one and the box door two need to be closed, and the motor and the hot air blower need to be started to dry. However, its drying efficiency is poor and it is not suitable for drying a large amount of medicinal materials. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a medicinal material drying device for pharmaceutical use, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a medicinal material drying device for pharmaceutical profession, comprising a base one and a base two, the top of the base two is fixedly connected to a drying box, the side of the drying box is provided with a ventilation hole, the front end of the drying box is provided with a box door, the top of the base one is provided with a drying mechanism, and the bottom of the interior of the drying box is provided with an up-throwing mechanism; the drying mechanism comprises a motor, a fan, and a transmission belt, the motor and the fan are all fixedly mounted on the top of the base one, the motor is fixedly connected to a rotating shaft through its output shaft, the front end of the fan is provided with an air inlet, the rear end of the fan is provided with a fan shaft, the fan shaft is transmission-connected to the rotating shaft through a transmission belt, the top of the fan is provided with an air outlet pipe, the end of the air outlet pipe away from the fan passes through and is fixedly connected to a heating box, the interior of the heating box is provided with an electric heating wire, the bottom of the heating box passes through and is fixedly connected to a connecting pipe, the bottom of the connecting pipe passes through and is fixedly connected to an air outlet hood, and the interior of the air outlet hood is provided with an air guide mechanism.

[0006] According to the above technical solution, the heating box and the top of the drying box are penetrated and fixedly connected, and the air outlet hood is located inside the drying box near the top. After the airflow passes through the drying box and is heated by the electric heating wire, it enters the air outlet hood through the connecting pipe and is finally blown out by the air outlet hood to dry the medicinal materials in the drying box.

[0007] The top of the slide cylinder is fixedly connected to a placing plate, and the surface of the slide cylinder is fixedly connected to the fixed plate, and the end of the piston rod 2 is fixedly connected to the bottom of the fixed plate.

[0008] According to the above technical solution, the driving gear is meshed with the driven gear, and the diameter of the driving gear is smaller than that of the driven gear. The rotation of the driving gear will drive the driven gear to rotate. The smaller the diameter of the driving gear is, the slower the speed at which the driven gear rotates one circle.

[0009] According to the above technical solution, the rotating gear is an incomplete gear, and the upper teeth of the rotating gear are adapted to the upper teeth of the gear rod. When the rotating gear rotates and its upper teeth mesh with the upper teeth of the gear rod, the gear rod will be driven to move rightward.

[0010] According to the above technical solution, the overall shape of the placement tray is circular, and a through hole is provided at the bottom of the placement tray. The circular placement tray is convenient for placing medicinal materials, and the through hole at the bottom of the placement tray allows air to circulate.

[0011] According to the above technical solution, the air guide mechanism includes a hydraulic tank and a cross bar. The hydraulic tank is fixedly connected to the inner bottom of the drying box. The internal piston at one end of the hydraulic tank is slidably connected to a pressure rod, and the internal piston at the other end of the hydraulic tank is slidably connected to a push rod. The cross bar passes through and is rotatably connected to the front end of the air outlet hood. The surface of the cross bar is fixedly connected to an air guide plate, and the top of the air guide plate is provided with an anti-complete blockage component.

[0012] According to the above technical solution, one end of the pressure rod away from the hydraulic chamber is fixedly connected to the bottom of the fixed plate, and one end of the push rod away from the hydraulic chamber is hingedly connected to the bottom of the wind guide plate. The fixed plate moves downward to press the pressure rod, and the downward movement of the pressure rod will drive the push rod to move upward through the hydraulic pressure in the hydraulic chamber. The upward movement of the push rod will cause the wind guide plate to rotate.

[0013] According to the above technical solution, the anti-complete blockage component includes a connecting rod and a connecting hole, one end of the connecting rod is fixedly connected to the top of the air guide plate, the other end of the connecting rod is fixedly connected to the limiting block, the surface of the connecting rod is slidably connected to the closing block, the surface of the connecting rod is sleeved with a compression spring, and the connecting hole is opened at the top of the air guide plate.

[0014] According to the above technical solution, the closing block is initially located inside the communicating hole, and the two ends of the compression spring respectively conflict with the bottom of the closing block and the top of the limit block. The closing block is located in the communicating hole so that the communicating hole is in a closed state, and the downward movement of the closing block will cause the compression spring to be compressed.

[0015] The present invention provides a medicinal material drying device for pharmaceutical use. It has the following beneficial effects:

[0016] (1) The present invention is provided with a drying mechanism so that when a large amount of medicinal materials needs to be dried, the motor can be turned on, and the motor drives the rotating shaft to rotate through its output shaft. The rotation of the rotating shaft drives the rotating shaft of the fan to rotate through the transmission belt. At this time, the airflow is discharged to the drying box through the air outlet pipe, and after being heated by the electric heating wire in the drying box, it enters the air outlet hood through the connecting pipe, and is finally discharged from the air outlet hood to dry the medicinal materials in the drying box. A large amount of medicinal materials can be dried at one time, and the drying efficiency is high.

[0017] (2) The present invention sets up an upward throwing mechanism so that the motor is turned on to drive the rotating shaft to rotate. When the rotating shaft rotates and drives the fan shaft to rotate through the transmission belt, the slide and the placement plate are driven to move downward through the cooperation of the driving gear, the driven gear, the rotating gear, the gear rod, the air pressure chamber and other components. Then the return spring rebounds and drives the slide and the placement plate to rebound and recover. In this process, due to inertia, the medicinal materials in the placement plate can be thrown up and rolled, preventing the bottom of the medicinal materials from being difficult to dry, thereby further improving the drying efficiency of the medicinal materials.

[0018] (3) The present invention provides an air guide mechanism so that when the slide moves downward and then bounces upward to recover, the wind direction of the airflow discharged from the air outlet hood will continuously change through the cooperation of the hydraulic chamber, pressure rod, push rod, air guide plate and other components, making the hot air in the drying box more uniform, thereby improving the drying effect.

The bottom of the connecting pipe 69 passes through and is fixedly connected to an air outlet cover 6 10, the heating box 67 is passed through and fixedly connected to the top of the drying box 3, and the air outlet hood 610 is located inside the drying box 3 near the top. The airflow passes through the drying box 3 and is heated by the electric heating wire 68, then enters the air outlet hood 610 through the connecting pipe 69, and is finally blown out by the air outlet hood 610 to dry the medicinal materials in the drying box 3. The air guide mechanism 8 is provided inside the air outlet hood 610, and the upper throwing mechanism 7 includes a driving gear 71, a connecting frame 72, an air pressure chamber 76 and a slide 710. The driving gear 71 is fixedly connected to the surface of the fan shaft 65, the bottom of the connecting frame 72 is fixedly connected to the top of the fan 63, the inner side of the connecting frame 72 is rotatably connected to the rotating rod 73, and the surface of the rotating rod 73 is fixedly connected to the rotating rod 73. The driven gear 74 and the rotating gear 75, the driving gear 71 meshes with the driven gear 74, and the diameter of the driving gear 71 is smaller than the diameter of the driven gear 74. The rotation of the driving gear 71 will drive the driven gear 74 to rotate. The smaller the diameter of the driving gear 71, the slower the speed at which the driven gear 74 rotates one circle. The air pressure chamber 76 passes through and is fixedly connected to the side of the drying box 3. The internal piston of one end of the air pressure chamber 76 is slidably connected to a piston rod 77. The end of the piston rod 77 away from the air pressure chamber 76 is fixedly connected to a gear rod 78. The rotating gear 75 is an incomplete gear, and the teeth on the rotating gear 75 match the teeth on the gear rod 78. The rotating gear 75 rotates and its upper teeth match the teeth on the gear rod 78. When engaged, the gear rod 78 moves rightward. The other end of the air pressure chamber 76 is slidably connected to the piston rod 2 79. A return spring 711 is provided inside the slide 710. The slide rod 712 is slidably connected to the slide 710 via the return spring 711. A placement plate 713 is fixedly connected to the top of the slide 710. The placement plate 713 is circular in shape and has a through hole at the bottom. The circular placement plate 713 facilitates the placement of medicinal materials. The through hole at the bottom of the placement plate 713 allows air to circulate. A fixed plate 714 is fixedly connected to the surface of the slide 710. The end of the piston rod 2 79 away from the air pressure chamber 76 is fixedly connected to the bottom of the fixed plate 714.

[0031] During use, when a large number of Chinese medicinal materials need to be dried, the front door 5 of the drying box 3 is opened, the medicinal materials are placed in the placement tray 713 in the drying box 3, and the motor 61 is turned on. The motor 61 drives the rotating shaft 62 to rotate through its output shaft. The rotation of the rotating shaft 62 drives the fan rotating shaft 65 to rotate through the transmission belt 611, thereby making the fan 63 run. The operation of the fan 63 allows the outside air to enter the fan 63 through the air inlet 64 and be discharged to the heating box 67 through the air outlet 66. The electric heating wire 68 in the heating box 67 will heat the incoming air. The heated air enters the air outlet cover 610 through the connecting pipe 69 and is finally blown out by the air outlet cover 610 to dry the medicinal materials in the drying box 3. The through holes at the bottom of the placement plate 713 allow the hot air to circulate, thereby achieving the goal of drying a large amount of medicinal materials at one time with high drying efficiency. When the fan shaft 65 rotates, it also drives the driving gear 71 to rotate, and the driving gear 71 rotates, which drives the driven gear 74 to rotate. The driving gear 71 has a smaller diameter, so the speed of driving the driven gear 74 to rotate one circle is slower, which plays a role of deceleration. The rotation of the driven gear 74 drives the rotating rod 73 to rotate, and the rotation of the rotating rod 73 drives the rotating gear 75 to rotate. At the beginning, the rotating gear 75 rotates and its upper teeth engage with the teeth on the gear rod 78, which drives the gear rod 78 to move to the right. The rightward movement of the gear rod 78 drives the piston rod 1 77 to move to the right. The rightward movement of the piston rod 1 77 drives the piston rod 2 79 downward through the air pressure in the air pressure chamber 76. The downward movement of the piston rod 2 79 drives the fixed plate 714 and the slide 710 downward. The downward movement of the slide 710 drives the placement plate 713 downward. , the return spring 711 is squeezed and gradually tightened, and when the rotating gear 75 rotates to the toothless part and disengages from the gear rod 78, the return spring 711 rebounds and drives the slide 710, the placement plate 713 and the fixed plate 714 to bounce upward and restore, the piston rod 2 79 moves upward to restore, the piston rod 1 77 and the gear rod 78 move to the left to restore, thus forming a cycle. In this process, due to inertia, the medicinal materials in the placement plate 713 can be thrown up and rolled, preventing the bottom of the medicinal materials from being difficult to dry, thereby further improving the drying efficiency of the medicinal materials.

[0032] On the basis of the above embodiment, in another embodiment of the present invention, the air guide mechanism 8 includes a hydraulic tank 81 and a cross bar 84. The hydraulic tank 81 is fixedly connected to the inner bottom of the drying box 3. The internal piston at one end of the hydraulic tank 81 is slidably connected to a pressure rod 82, and the internal piston at the other end of the hydraulic tank 81 is slidably connected to a push rod 83. The cross bar 84 passes through and is rotatably connected to the front end of the air outlet hood 610. The surface of the cross bar 84 is fixedly connected to an air guide plate 85. The end of the pressure rod 82 away from the hydraulic tank 81 is fixedly connected to the bottom of the fixed plate 714, and the end of the push rod 83 away from the hydraulic tank 81 is hingedly connected to the bottom of the air guide plate 85. The downward movement of the fixed plate 714 will press down the pressure rod 82, and the downward movement of the pressure rod 82 will drive the push rod 83 to move upward through the hydraulic pressure in the hydraulic tank 81. The push rod 83 moves upward The movement will cause the wind guide plate 85 to rotate. An anti-complete blockage component 9 is provided on the top of the wind guide plate 85. The anti-complete blockage component 9 includes a connecting rod 91 and a connecting hole 95. One end of the connecting rod 91 is fixedly connected to the top of the wind guide plate 85, and the other end of the connecting rod 91 is fixedly connected to the limiting block 92. The surface of the connecting rod 91 is slidably connected to the closing block 93. The surface of the connecting rod 91 is sleeved with a compression spring 94. The connecting hole 95 is opened at the top of the wind guide plate 85. The closing block 93 is initially located inside the connecting hole 95. The two ends of the compression spring 94 respectively conflict with the bottom of the closing block 93 and the top of the limiting block 92. The closing block 93 is located in the connecting hole 95 so that the connecting hole 95 is in a closed state. The downward movement of the closing block 93 will cause the compression spring 94 to be compressed.

[0033] When in use, the slide 710, the placement plate 713 and the fixed plate 714 repeatedly move downward and then bounce upward. The fixed plate 714 moves downward to press the pressure rod 82. The downward movement of the pressure rod 82 will drive the push rod 83 to move upward through the hydraulic pressure in the hydraulic chamber 81. The upward movement of the push rod 83 will cause the air guide plate 85 to rotate. When the fixed plate 714 bounces upward and recovers, the pressure rod 82 moves upward and is restored. At this time, the push rod 83 drives the air guide plate 85 to rotate and restore. The back and forth rotation of the air guide plate 85 causes the wind direction discharged from the air outlet hood 610 to change continuously, making the hot air in the drying box 3 more uniform, thereby improving the drying effect. The compression spring 94 rebounds and drives the closing block 93 to move upward to restore and re-close the connecting hole 95, which will not affect the guide of the wind guide plate 85, thereby preventing the air outlet hood 610 from being completely blocked and causing damage to the fan 63.

[0034] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
