DETAILED DESCRIPTION

[0033] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0034] like Figure 1-Figure 9 As shown, a preparation device for preparing biodegradable plastics using wine lees waste includes a device body 1, a top plate 2 is fixed on the top of the device body 1 through a plurality of connecting plates, a placement plate 3 is arranged inside the device body 1, wine lees are placed on the placement plate 3, and the wine lees on the placement plate 3 are dried by an external drying mechanism, the drying mechanism can be installed on the side wall of the device body 1 or not in contact with the device body 1, a first motor 9 is installed at the bottom of the top plate 2, a rotating column 6 is fixed to the output end of the first motor 9, a stirring block 8 is installed at the bottom of the rotating column 6, and the stirring block 8 stirs and dries the wine lees;

[0035] When the first motor 9 is driven, the rotating column 6 and the stirring block 8 can be driven to rotate, and the wine lees drying on the placement plate 3 are stirred and turned by the rotation of the stirring block 8, so that the wine lees drying effect is better;

[0036] A driving mechanism is installed between the rotating column 6 and the top plate 2, and the driving mechanism is used to drive the stirring block 8 to move.

[0037] See attached Figure 2 and attached Figure 3 The driving mechanism includes a first meshing gear 5 fixed on the outside of the rotating column 6, and an annular meshing ring 4 is fixed to the bottom of the top plate 2 through a plurality of connecting plates. The shape of the annular meshing ring 4 is an annular spiral structure. The first meshing gear 5 is meshed and connected with the inner wall of the annular meshing ring 4. When the first meshing gear 5 rotates, it moves along the track of the annular meshing ring 4. A sliding block is installed on the top of the first motor 9, and a sliding groove with the same shape as the annular meshing ring 4 is provided at the bottom of the top plate 2. The sliding block slides along the sliding groove;

[0038] When the first motor 9 is driven, the rotating column 6 is driven to rotate, and the first meshing gear 5 is driven to rotate. Through the meshing connection between the first meshing gear 5 and the annular meshing ring 4, the first meshing gear 5 can move along the inner wall of the annular meshing ring 4 when meshing with the annular meshing ring 4. Through the structural shape of the annular meshing ring 4 itself, the first meshing gear 5 can stir and move the lees on the surface of the top plate 2 comprehensively when moving, so that the lees can be turned and dried better;

[0039] See attached Figure 3 A felt gear 26 is also fixed to the outside of the rotating column 6, and the felt gear 26 is also meshed with the annular meshing ring 4, and the felt gear 26 is located at the upper part of the first meshing gear 5. Through the setting of the felt gear 26, the user can use a needle or other components to inject lubricating liquid into the felt gear 26, and through the meshing connection between the felt gear 26 and the annular meshing ring 4, the annular meshing ring 4 can be lubricated, and the setting of the felt gear 26 at the upper part of the first meshing gear 5 allows the lubricating liquid on the felt gear 26 and the annular meshing ring 4 to move downward due to gravity, thereby obtaining a lubricating effect on the first meshing gear 5 and the annular meshing ring 4, refer to the attached Figure 4 A receiving plate 27 is fixed to the bottom of the annular meshing ring 4 and close to the inner side of the felt gear 26, and a sponge sheet 28 is arranged on the inner side of the top of the receiving plate 27. The receiving plate 27 is arranged so that the receiving plate 27 can collect the lubricating liquid dripping from the first meshing gear 5 and the annular meshing ring 4. The sponge sheet 28 is arranged to absorb the lubricating liquid and prevent the lubricating liquid from flowing out. The first meshing gear 5 starts slowly, and the centrifugal force of the first meshing gear 5 and the felt gear 26 is not enough to throw out the lubricating liquid.

[0040] Both ends of the annular meshing ring 4 are fixed with elastic structures, which are used to drive the stirring block 8 to change its angle;

[0041] See attached Figure 6 The elastic structure includes a connecting block 10 provided at both ends of the annular meshing ring 4, the distance between the teeth on the connecting block 10 and the teeth at the end of the annular meshing ring 4 is equal to the distance between two adjacent teeth of the annular meshing ring 4, the connecting block 10 and the top and bottom of the annular meshing ring 4 are respectively fixed with a first fixing block 11 and a second fixing block 12, and a first spring 13 is fixed between the first fixing block 11 and the second fixing block 12, the first fixing block 11 is close to the side of the second fixing block 12 and is located inside the first spring 13. A limiting rod 14 is fixed, and the limiting rod 14 is slidably connected to the second fixing block 12, and the limiting rod 14 is used to prevent the first spring 13 from tilting toward the outside when the first spring 13 is compressed, thereby ensuring the stability of the first spring 13;

[0042] After the teeth on the surface of the first meshing gear 5 and the annular meshing ring 4 mesh with each other and move until they reach the end of the annular meshing ring 4, the first meshing gear 5 continues to rotate until it meshes with the teeth on the connecting block 10, and drives the connecting block 10 to move toward the direction close to the annular meshing ring 4, and compresses the first spring 13. When the first meshing gear 5 continues to rotate until the teeth on the connecting block 10 rotate to the gap between the two teeth of the first meshing gear 5, the connecting block 10 is reset by the first spring 13, and then the teeth on the next first meshing gear 5 continue to push the connecting block 10 back, thereby preventing the first meshing gear 5 from rotating to lose contact with the annular meshing ring 4, thereby causing damage to the mechanism;

[0043] On the other hand, through this arrangement, after the first meshing gear 5 drives the stirring block 8 to rotate a certain angle, the output end of the first motor 9 is reversed, thereby driving the stirring block 8 to reverse, and the stirring block 8 is rotated to a different angle from the original angle through the rotation of the stirring block 8, and then when moving toward the other end of the annular meshing ring 4, the lees can be stirred and turned at different angles, thereby achieving a better stirring effect on the lees and ensuring a drying effect on the lees;

[0044] See attached Figure 7 The inside of the device body 1 is rotatably connected with a rotating rod 16, and a second meshing gear 17 is fixed to the outside of the rotating rod 16. A second motor 18 is installed on the outside of the device body 1. The output end of the second motor 18 passes through the device body 1 and is connected to the end of the rotating rod 16. The bottom of the placement plate 3 is slidably connected with a ring gear 15, and the ring gear 15 is meshed with the rotating rod 16.

[0045] When the output end of the second motor 18 rotates, it can drive the rotating rod 16 and the second meshing gear 17 to rotate, and through the meshing connection between the second meshing gear 17 and the ring gear 15, the second meshing gear 17 can drive the ring gear 15 to rotate, and the placement plate 3 is driven to rotate through the ring gear 15, so that when the stirring block 8 turns over the lees on the placement plate 3, the placement plate 3 follows the rotation, thereby achieving a better effect of turning over the lees;

[0046] See attached Figure 7 and attached Figure 8 , an abutment block 19 is installed on the outer side of the rotating rod 16. When the rotating rod 16 rotates, the abutment block 19 rotates accordingly and abuts against the placement plate 3;

[0047] When the rotating rod 16 rotates, the abutment block 19 can be driven to rotate at the same time. The abutment block 19 is rotated to abut against the placement plate 3, thereby driving the placement plate 3 to vibrate reciprocatingly. The ring gear 15 is slidably connected to the placement plate 3, so that when the placement plate 3 vibrates up and down, the ring gear 15 can be slidably connected to the ring gear 15 to prevent the ring gear 15 from following the movement, so that the ring gear 15 can always be meshed with the second meshing gear 17. The ring gear 15 is rotatably connected to the inner wall of the device body 1, so that the ring gear 15 can remain stationary.

[0048] An adjustment mechanism is installed in the abutment block 19, and the adjustment mechanism is used to adjust the position of the abutment block 19;

[0049] See attached Fig. 9 The adjusting mechanism includes a mounting groove 20 arranged inside the abutment block 19, and the mounting groove 20 is at the same position as the center of the rotating rod 16, and a threaded rod 21 is vertically rotatably connected inside the rotating rod 16, and the threaded rod 21 extends into the abutment block 19 and is threadedly connected to the abutment block 19, and a guide rod 22 is vertically fixed to the outside of the rotating rod 16, and the guide rod 22 extends into the abutment block 19 and is slidably connected to the abutment block 19, and a third motor 23 is also installed in the rotating rod 16, and the output end of the third motor 23 is connected to the end of the threaded rod 21;

[0050] When adjusting the position of the abutment block 19, the third motor 23 can be driven so that the output end of the third motor 23 drives the threaded rod 21 to rotate, and through the threaded connection between the threaded rod 21 and the abutment block 19, and through the sliding connection between the guide rod 22 and the abutment block 19, the abutment block 19 can be moved up and down by the rotation of the threaded rod 21, so that the distance between the abutment block 19 and the placement plate 3 can be adjusted, and then the vibration effect of the placement plate 3 can be adjusted. When there are more lees placed on the placement plate 3 or in other situations, the position of the abutment block 19 can be adjusted, so that the amplitude of the vibration of the placement plate 3 can be increased;

[0051] A conductive ring may be disposed on the rotating rod 16 to supply power to the third motor 23 externally, and a rechargeable battery may also be disposed inside the rotating rod 16 to supply power to the third motor 23 using the battery.

[0052] A movable structure adapted to allow the placement plate 3 to move up and down is installed on the top of the stirring block 8;

[0053] See attached Figure 5 The movable structure includes a sliding column 7 fixed on the top of the stirring block 8, the stirring block 8 is mounted on the rotating column 6 through the sliding column 7, a mounting cavity 24 is provided inside the rotating column 6, and the sliding column 7 is slidably connected in the mounting cavity 24, a second spring 25 is also installed in the mounting cavity 24, and the second spring 25 is connected to the rotating column 6 and the sliding column 7;

[0054] When the placing plate 3 vibrates, the second spring 25 is arranged so that the second spring 25 can push the sliding column 7 and the stirring block 8 downward, and then contact the placing plate 3, so that the stirring block 8 can keep the turning effect on the lees unchanged when rotating the lees.

[0055] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
