[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] A drying device for the production of Shujing tablets, as Figures 1 to 4 shown, includes a housing 1, a drum 3, a drum cover 11, a driving motor 26 and a hot air blower 32. An annular plate 4 is fixed inside the drum 3, and a containing groove 5 is formed between the side wall of the drum 3 and the annular plate 4. Rollers 2 and a hollow annular plate 33 are fixed on the inner wall of the housing 1.

[0029] The drum 3 is connected to the drum cover 11 through a detachable fixing mechanism. The detachable fixing mechanism includes a connecting seat 6 fixed on the drum 3, a cross bar 14 and a longitudinal bar 13 slidably connected inside the connecting seat 6, and a connecting block 12 fixed on the drum cover 11. An installation plate 20 is fixed at the end of the cross bar 14. A first spring 21 wound around the outside of the cross bar 14 is connected between the installation plate 20 and the connecting seat 6. A connecting plate 22 is fixed between the installation plates 20. Inclined surfaces 15 that cooperate with each other are provided on the cross bar 14 and the longitudinal bar 13, and a positioning hole 19 that cooperates with the longitudinal bar 13 is formed on the connecting block 12.

[0030] A groove 16 is formed inside the connecting seat 6. An installation block 17 is fixed on the longitudinal bar 13, and a second spring 18 is connected between the installation block 17 and the inner wall of the groove 16.

[0031] When the tablet needs to be dried, the connecting plate 22 is pulled outwards against the elastic force of the first spring 21, so that the longitudinal rod 13 moves upwards under the elastic force of the second spring 18. At this time, the longitudinal rod 13 is removed from the positioning hole 19, and then the connecting block 12 is pulled out from the connecting seat 6, and the cylinder cover 11 can be removed. After the tablet is placed in the storage groove 5, the above operations are performed in reverse to cover the cylinder cover 11.

[0032] A ring hole 23 matching with the cylinder cover 11 is formed in the connecting plate 22, and the arrangement of the ring hole 23 facilitates the removal of the cylinder cover 11.

[0033] In the technical solution of the present application, the inclined surface 15 is mainly provided to enable the cross bar 14 to push the longitudinal rod 13 into the positioning hole 19 under the elastic force of the first spring 21 to complete the operation of covering the cylinder cover 11. Therefore, the elastic force of the first spring 21 should be greater than the elastic force of the second spring 18. The first spring 21 can be selected as a spring with a stiffness coefficient of 50 N / m, while the second spring 18 can be selected as a spring with a stiffness coefficient of 20 N / m.

[0034] A sliding and rolling mechanism matching with the roller 2 is arranged on the roller 3. The sliding and rolling mechanism includes a cross plate 7 fixed on the roller 3 and an arc-shaped connecting plate 8 fixed between the cross plates 7. A transverse sliding groove 9 for slidingly matching with the roller 2 is formed in the cross plate 7, and a longitudinal rolling groove 10 communicating with the transverse sliding groove 9 is formed in the arc-shaped connecting plate 8 and the cross plate 7.

[0035] After the cylinder cover 11 is covered, the transverse sliding groove 9 on the cross plate 7 is aligned with the bottom arc surface of the roller 2, so that the roller 3 can be horizontally moved into the housing 1. When the roller 2 moves to the intersection of the transverse sliding groove 9 and the longitudinal rolling groove 10, the movement is stopped. At this time, the rotating shaft 27 extends out of the housing 1.

[0036] A through hole matching with the rotating shaft 27 is formed in the side wall of the housing 1 close to the driving motor 26, and a revolving door 25 is hinged on the side wall of the housing 1 far from the driving motor 26. The through hole is provided so that the rotating shaft 27 can extend out of the housing 1 to be in transmission connection with the driving shaft of the driving motor 26, and the revolving door 25 is provided for convenient taking and placing of the roller 3.

[0037] In the technical solution of the present application, an observation window can be arranged on the housing 1 to facilitate observing the moving position of the roller 2 on the transverse sliding groove 9 and the longitudinal rolling groove 10 and observing whether the roller 2 is aligned with the transverse sliding groove 9.

[0038] The driving motor 26 is fixed to the housing 1 through a connecting rod, and the driving motor 26 is drivingly connected to the drum 3 through a transmission mechanism. The transmission mechanism includes a rotating shaft 27 fixed to the drum 3. An accommodation groove for mating with the driving shaft of the driving motor 26 is provided on the rotating shaft 27. A limiting block 29 is fixed on the driving shaft of the driving motor 26. A limiting opening 30 that slidably mates with the limiting block 29 and communicates with the accommodation groove is provided on the rotating shaft 27. Mounting holes 31 are provided on both the rotating shaft 27 and the driving shaft of the driving motor 26.

[0039] The mounting holes 31 on the rotating shaft 27 and the driving shaft of the driving motor 26 are connected and fixed by fixing bolts. Internal threads for mating with the fixing bolts are provided on the inner walls of the mounting holes 31.

[0040] When the rotating shaft 27 extends outside the housing 1, manually adjust the driving shaft of the driving motor 26 so that the limiting block 29 is aligned with the limiting opening 30, facilitating the driving shaft of the driving motor 26 to be inserted into the accommodation groove inside the rotating shaft 27. After the limiting block 29 completely enters the limiting opening 30, then use the fixing bolts to fix the mounting holes 31 on the rotating shaft 27 and the driving shaft of the driving motor 26 to prevent the driving shaft of the driving motor 26 from disengaging from the rotating shaft 27. The setting of the transmission mechanism facilitates installation and disassembly.

[0041] In the technical solution of the present application, the driving motor 26 uses a non - brake motor, that is, the driving shaft of the driving motor 26 can rotate under the action of an external force when the machine stops.

[0042] In addition, in order to ensure that the fixing bolts can be screwed into the mounting holes 31 on the rotating shaft 27 and the driving shaft of the driving motor 26, color marks can be set on the limiting block 29 and the rotating shaft 27. When the color marks on the limiting block 29 and the rotating shaft 27 are in the same vertical plane, the internal threads of the mounting holes 31 on the rotating shaft 27 and the internal threads of the mounting holes 31 on the driving shaft of the driving motor 26 can be connected, facilitating the fixing bolts to be screwed in.

[0043] Hot air holes are evenly provided on the inner wall of the hollow ring plate 33. The air outlet of the hot air blower 32 is communicated with the hollow ring plate 33 through a connecting pipe. The hot air blown out by the hot air blower 32 enters the hollow ring plate 33 and blows towards the drum 3 from the hot air holes. At the same time, the driving motor 26 drives the drum 3 to rotate, enabling the tablets in the containing groove 5 to be evenly heated, achieving a good drying effect.

[0044] A handle 24 is fixed on the cylinder cover 11. Ventilation holes are evenly provided on the drum 3 and the annular plate 4. The setting of the ventilation holes facilitates the hot air to enter the containing groove 5 to effectively dry the tablets.

[0045] In the technical solution of this application, the roller 2, the cross plate 7 and the connecting seat 6 are all arranged in a "cross" shape distribution with respect to the drum 3. The "cross" shape distribution of the roller 2 can ensure the stability of the rotation of the drum 3. In addition, an air outlet can also be provided on the housing 1 to ensure the air pressure balance inside the housing 1.

[0046] The original Shujing tablets are spray-dried after extraction and concentration to obtain dry extracts. The technical solution of this application can effectively improve the drying efficiency, shorten the drying time of the extracts of this variety, and ensure the content of the dry extracts.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
