[0032] The material holding component includes a mesh disk 5, a pressing net 6 is movably embedded in the upper end of the mesh disk 5, and the pressing net 6 is rotatably connected to the mesh disk 5 through a mounting shaft 7. The mesh disk 5 and the pressing net 6 can clamp the sheet-like Chinese herbal medicine slices. A mounting hole is opened on the mesh disk 5 corresponding to the mounting shaft 7, and the height of the mounting hole is greater than the diameter of the mounting shaft 7. A convex plate 8 is fixedly installed on the end of the pressing net 6 away from the mounting shaft 7.

[0033] Connecting shafts 9 are fixedly installed at both ends of the net disk 5, and the connecting shafts 9 are movably embedded in the upper end of the support seat 4. A gear 10 is fixedly sleeved on the outer side of the connecting shaft 9, and the gear 10 is movably fitted with the inner wall of the support seat 4. Two symmetrically distributed tooth plates 11 are fixedly installed on the inner side of the drying chamber 3, and the connection between the gears 10 and the tooth plates 11 is meshing contact. The tooth plates 11 can drive the net disk 5 to rotate 180° through the gear 10.

[0034] The positioning assembly includes two pin rods 12 installed on the outside of the gear 10 and symmetrically distributed, and the pin rods 12 are located inside the support seat 4. The cross-sectional shape of the pin rod 12 is circular, and a washer 13 is fixedly sleeved on the outside of the pin rod 12. The pin rod 12 and the washer 13 can move left and right inside the support seat 4, and a spring 14 is movably sleeved on the outside of the pin rod 12.

The outer side of the support seat 4 corresponds to the outer side of the pin rod 12 and is movably sleeved with a U-shaped baffle 17.

[0036] Working principle: the personnel first lay the sliced ​​Chinese herbal medicine pieces flat on the mesh plate 5, and then rotate the pressing net 6 to press on the laid Chinese herbal medicine pieces, so that the mesh plate 5 and the pressing net 6 clamp the Chinese herbal medicine pieces, and then install the material holding component on the support seat 4 at the loading station, and make the mesh plate 5 face upward. When installing the material holding component on the support seat 4, the personnel embed the connecting shaft 9 at the upper end of the support seat 4, and the pin rod 12 will be driven by the spring 14 to embed into the hemispherical groove 16 on the connecting shaft 9, which can position the material holding component and prevent the material holding component from rotating on the support seat 4;

[0037] Afterwards, the conveyor belt 2 sends the material holding component containing the Chinese herbal medicines into the drying chamber 3 for drying. After one side of the Chinese herbal medicines is dried, the gear 10 in the material holding component moves to the tooth plate 11 and continues to move. The tooth plate 11 can drive the gear 10 and the material holding component to flip 180°, and the pin 12 will be embedded in the corresponding hemispherical groove 16 on the connecting shaft 9, which is beneficial to drying the other side of the Chinese herbal medicines, thereby facilitating the device to dry the Chinese herbal medicines evenly, and in the process of flipping the Chinese herbal medicines, it can effectively prevent the Chinese herbal medicines from colliding with each other and breaking.

[0038] Example 2: Please refer to Figure 5 , Figure 6 The present embodiment further explains the first embodiment. Four pin plates 18 symmetrically distributed in pairs are movably embedded on the outer side of the U-shaped baffle 17, and the connection between the pin plates 18 and the support seat 4 is a fixed connection. The pin plates 18 are slidably connected to the U-shaped baffle 17 through a limiting straight groove. The U-shaped baffle 17 resists the pin rod 12 and can prevent the pin rod 12 from moving inside the support seat 4. Two symmetrically distributed metal springs 19 are installed on the inner side of the U-shaped baffle 17, and the end of the metal spring 19 away from the U-shaped baffle 17 is fixedly connected to the support seat 4, and the shape of the metal spring 19 is V-shaped.

[0039] The U-shaped baffle 17 is provided with two symmetrically distributed through holes 20, and the diameter of the through hole 20 is larger than the diameter of the pin rod 12. When the through hole 20 is concentric with the pin rod 12, the pin rod 12 can move inside the support seat 4. A triangular stopper 21 is fixedly installed at the upper end and inner side of the machine base 1 corresponding to the loading station, the flipping station and the disassembly station of the material holding assembly. The cross-sectional shape of the triangular stopper 21 is an isosceles triangle, and the connection between the triangular stopper 21 and the U-shaped baffle 17 is a movable abutment.

[0040] In this embodiment: when the support seat 4 is located at the loading station, the turning station and the disassembly station of the material holding assembly, the U-shaped baffle 17 will be driven by the triangular block 21 to approach the support seat 4, and the through hole 20 on the U-shaped baffle 17 will be concentric with the pin 12. At this time, the pin 12 can move inside the support seat 4, which is conducive to the rotation of the connecting shaft 9 on the support seat 4 and the disassembly and installation of the connecting shaft 9;

[0041] When the U-shaped baffle 17 moves with the support seat 4 and disengages from the triangular stopper 21, the U-shaped baffle 17 will move back driven by the elastic force of the metal spring 19. At this time, the U-shaped baffle 17 will resist the pin rod 12 to prevent the pin rod 12 from moving inside the support seat 4, which is beneficial for the pin rod 12 to lock the connecting shaft 9, thereby preventing the material holding component from detaching from the support seat 4 due to inertia and gravity when it moves to the inner side of the machine base 1 with the conveyor belt 2.

[0042] Example 3: Please refer to Figure 7 , Figure 8 , this embodiment further explains the second embodiment, the limit assembly includes two baffle rods 22 installed on the upper side of the convex plate 8, and the two baffle rods 22 are provided with a beveled edge portion at one end close to each other, the convex plate 8 is in sliding contact with the baffle rod 22 through the beveled edge portion, and the beveled edge portion is used to reduce the friction resistance between the convex plate 8 and the baffle rod 22, the outer side of the baffle rod 22 is movably sleeved with a sleeve seat 23, and the connection between the sleeve seat 23 and the net disk 5 is a fixed connection, the ends of the two baffle rods 22 that are away from each other are movably abutted with a spring 24, and the end of the spring 24 that is away from the baffle rod 22 is movably abutted with the sleeve seat 23, a connecting plate 25 is fixedly embedded on the outer side of the baffle rod 22, and the connection between the connecting plate 25 and the sleeve seat 23 is a sliding connection.

[0043] An oblique support rod 26 is hingedly installed on the outer side of the sleeve 23 at the upper end of the connecting plate 25, and an articulated seat 27 is hingedly installed on the end of the oblique support rod 26 away from the connecting plate 25. A push rod 28 is fixedly installed between the two articulated seats 27. By pressing the push rod 28, the two baffle rods 22 can be driven away from each other. A ball 29 is movably embedded in the end of the push rod 28 away from the baffle rod 22, and the connection between the ball 29 and the triangular block 30 is rolling contact.

[0044] In this embodiment: after the material holding assembly moves to the inside of the machine base 1 along the conveyor belt 1 2, since the material holding assembly is flipped 180° inside the drying chamber 3, after the material holding assembly is inside the machine base 1, the pressing net 6 is located at the lower side of the net plate 5, and when the ball 29 at the end of the push rod 28 moves along the triangular stopper 2 30, the push rod 28 will approach the convex plate 8 under the drive of the triangular stopper 2 30. In this process, the push rod 28 will drive the two stoppers 22 away from each other through the two diagonal support rods 26. Without the obstruction of the two stoppers 22 to the convex plate 8, the pressing net 6 will rotate open under the action of gravity, which is conducive to the dried Chinese herbal medicine pieces sliding along the pressing net 6, which is conducive to the rapid discharge of Chinese herbal medicine pieces;

[0045] After the opened material holding assembly moves to the rightmost end of the machine base 1 , the personnel pin rod 12 can move inside the support base 4 , and the personnel can easily remove the material holding assembly from the support base 4 .

[0046] Example 4: Please refer to Figure 2 , Figure 4 This embodiment further explains the third embodiment. A conveyor belt 2 35 is installed on the inner bottom surface of the machine base 1, and a bent support rod 31 is installed on the upper side of the conveyor belt 2 35. The connection between the bent support rod 31 and the machine base 1 is a fixed connection. A buffer sleeve 32 is fixedly sleeved on the outer side of the bent support rod 31. The buffer sleeve 32 is used for buffering and shock absorbing the pressing net 6. A top bead 33 is fixedly embedded on the upper end of the convex plate 8. A plurality of grooves 34 distributed at equal distances are opened on the outer side of the bent support rod 31, and the top bead 33 is in sliding contact with the bent support rod 31 through the groove 34.

[0047] In this embodiment: after the pressing net 6 is rotated and opened, the convex plate 8 will hit the buffer sleeve 32, which is beneficial to buffer and reduce shock of the pressing net 6, and the conveyor belt 2 continues to convey the material holding component. At this time, the top bead 33 at the upper end of the convex plate 8 will slide in contact with the bent support rod 31 through multiple grooves 34, which can cause the material holding component to produce continuous micro-vibration, and can assist the material holding component to shake off the dried Chinese herbal medicine slices. The shaken off Chinese herbal medicine slices slide onto the conveyor belt 2 35 through the tilted opened pressing net 6.
