[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Such as Figures 1 - 4As shown in the figure, a soft capsule drying device includes a first support frame 1, a drying cylinder 8 for carrying soft capsules, and a heating component for generating hot air flow. A first limiting sleeve 2 is rotatably connected to the first support frame 1. An electric telescopic rod 3 is arranged on one side of the first support frame 1. The extending end of the electric telescopic rod 3 is rotatably fitted with a second limiting sleeve 4. The drying cylinder 8 is coaxially rotatably connected inside the first limiting sleeve 2 and the second limiting sleeve 4. The electric telescopic rod 3 can drive the second limiting sleeve 4 to move up and down, so as to adjust the height of the opening end of the drying cylinder 8. The heating component is arranged on the side of the first limiting sleeve 2 away from the electric telescopic rod 3 and is rotatably fitted with the drying cylinder 8, so as to avoid the rotating drying cylinder 8 affecting the heating component. One end of the second limiting sleeve 4 away from the first support frame 1 is provided with a cylinder cover 13 that cooperates with one end of the drying cylinder 8. The cylinder cover 13 is fixed on the second limiting sleeve 4 and is responsible for blocking the opening at one end of the drying cylinder 8. A ventilation opening is provided on the cylinder cover 13 to facilitate the outflow of hot air flow. A driving component for driving the drying cylinder 8 to rotate is arranged on the second limiting sleeve 4; during use, the soft capsules are put into the drying cylinder 8 from the opening at one end of the drying cylinder 8, and then the cylinder cover 13 is fixed on the second limiting sleeve 4 to block the feeding port of the drying cylinder 8. The heating component is started, and the heating component generates hot air flow to heat the soft capsules. The driving component is started, and the driving component drives the drying cylinder 8 to rotate along the axis, driving the soft capsules to continuously move up and down in the drying cylinder 8, so that the soft capsules are heated more evenly. The hot air flow surges from one end of the drying cylinder 8 to the other end, and these hot air flows will push the soft capsules moving up and down towards one end of the drying cylinder 8. The height of one end of the drying cylinder 8 can be adjusted by the electric telescopic rod 3, so that one end of the opening of the drying cylinder 8 is slightly inclined upwards to control the appropriate position of the soft capsules to move up and down inside the drying cylinder 8. When it is necessary to increase the output air flow of the heating component, it is necessary to increase the inclination angle of one end of the opening of the drying cylinder 8 to avoid the soft capsules being pushed to one end of the opening of the drying cylinder 8. When the drying is completed, the heating component and the driving component are turned off, the cylinder cover 13 is removed from the second limiting sleeve 4, the height of one end of the opening of the drying cylinder 8 is adjusted by the electric telescopic rod 3 to make the opening of the drying cylinder 8 inclined downwards, and the driving component is started to drive the drying cylinder 8 to rotate. The soft capsules will fall out under the action of gravity and the drying cylinder 8, thus realizing the operation of automatic feeding.

[0024] In some specific implementation schemes, in order to realize the automatic rotation of the drying cylinder 8, the driving component includes a motor 5 fixedly connected to the second limiting sleeve 4. The output end of the motor 5 is fixedly connected with a driving wheel 6. A transmission wheel 7 that cooperates with the driving wheel 6 is coaxially and fixedly connected to the drying cylinder 8; when it is necessary to rotate the drying cylinder 8, the motor 5 can be started. The motor 5 drives the driving wheel 6 to rotate. The driving wheel 6 drives the transmission wheel 7 to rotate. The transmission wheel 7 drives the drying cylinder 8 to rotate, thus realizing the effect of the drying cylinder 8 driving the soft capsules to move.

[0025] In some specific embodiments, to achieve the heating effect on the soft capsules, the heating assembly includes a hot air blower 11 disposed on one side of the first support frame 1. The output end of the hot air blower 11 is connected with a telescopic hose 9 in a matching manner. A tapered sleeve 16 is connected between the telescopic hose 9 and the first limiting sleeve 2, so as to ensure that the hot air flow can enter the drying cylinder 8 along the tapered sleeve 16. The tapered sleeve 16 is rotatably connected to one end of the drying cylinder 8 to prevent the tapered sleeve 16 from affecting the normal operation of the drying cylinder 8. When the drying operation needs to be carried out, the hot air blower 11 can be started. The hot air blower 11 outputs hot air flow, and the hot air flow enters the drying cylinder 8 through the telescopic hose 9 and the tapered sleeve 16, thereby realizing the heating of the soft capsules.

[0026] In some specific embodiments, to ensure the heating effect, a heat preservation sleeve 10 is fixedly connected to the first limiting sleeve 2. The heat preservation sleeve 10 is arranged around and in cooperation with the side surface of the drying cylinder 8. One end of the heat preservation sleeve 10 far from the first limiting sleeve 2 is fixedly connected to the second limiting sleeve 4, so that the heat preservation sleeve 10 can be arranged around the outside of the heat preservation sleeve 10. A heating pipe 14 is arranged around the heat preservation sleeve 10. The input end of the heating pipe 14 is fixedly connected to the ventilation opening on the cylinder cover 13. After the hot air flow output by the hot air blower 11 passes through the drying cylinder 8, it enters the heating pipe 14 through the ventilation opening on the cylinder cover 13, and the drying cylinder 8 is heated secondarily by the heating pipe 14 arranged around the outside of the drying cylinder 8, thereby realizing the secondary utilization of the hot air flow, improving the utilization rate of the hot air flow, and ensuring the drying effect.

[0027] In some specific embodiments, to improve the drying effect of the hot air flow on the soft capsules, a plurality of groups of handling plates 12 are fixedly connected to the inner wall of the drying cylinder 8 at equal intervals in a circumferential manner. When the drying cylinder 8 rotates, it drives the handling plates 12 to move. The handling plates 12 drive the soft capsules to move along the inner wall of the drying cylinder 8. When the soft capsules move to a certain height under the action of the handling plates 12, they will fall to the bottom of the drying cylinder 8 under the action of gravity, thereby increasing the degree of up-and-down movement of the soft capsules, enabling the air flow to contact the surface of the soft capsules with a higher probability, and thus improving the efficiency of heat exchange.

[0028] In some specific embodiments, to prevent the soft capsules from falling into the tapered sleeve 16, a wind shielding plate 15 is arranged inside the tapered sleeve 16. One end of each group of handling plates 12 is fixedly connected to the wind shielding plate 15, and there is a gap between the wind shielding plate 15 and the inner wall of the drying cylinder 8. The hot air flow output by the hot air blower 11 will gush out concentratedly from the gap between the wind shielding plate 15 and the inner wall of the drying cylinder 8. The narrow space improves the thrust of the air flow and pushes the soft capsules away from the wind shielding plate 15. During the up-and-down movement of the soft capsules inside the drying cylinder 8, the wind shielding plate 15 can play a shielding role to prevent the soft capsules from entering the tapered sleeve 16.

[0029] To facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will be described below in combination with a specific application scenario:

[0030] During use, the soft capsules are put into the drying cylinder 8 through the opening at one end of the drying cylinder 8, and then the cylinder cover 13 is fixed on the second limiting sleeve 4 to block the feeding port of the drying cylinder 8. The hot air blower 11 can be started, and the hot air blower 11 outputs hot air flow. The hot air flow enters the drying cylinder 8 through the telescopic hose 9 and the conical sleeve 16, so as to realize the heating of the soft capsules. The motor 5 is started, the motor 5 drives the driving wheel 6 to rotate, the driving wheel 6 drives the driven wheel 7 to rotate, and the driven wheel 7 drives the drying cylinder 8 to rotate, driving the soft capsules to move up and down continuously in the drying cylinder 8, so that the soft capsules are heated more evenly. The hot air flow surges from one end of the drying cylinder 8 to the other end, and these hot air flows will push the soft capsules moving up and down to move towards one end of the drying cylinder 8. The height of one end of the drying cylinder 8 can be adjusted by the electric telescopic rod 3, so that the opening end of the drying cylinder 8 is slightly tilted upward to control the appropriate position of the soft capsules to move up and down inside the drying cylinder 8. When the weight of the soft capsules to be dried is relatively light, the output air flow of the hot air blower 11 can be reduced, or the tilt angle of the opening end of the drying cylinder 8 can be increased, so as to prevent the soft capsules from being pushed to the opening end of the drying cylinder 8. After drying is completed, the hot air blower 11 and the motor 5 are turned off, the cylinder cover 13 is removed from the second limiting sleeve 4, the height of the opening end of the drying cylinder 8 is adjusted by the electric telescopic rod 3 to make the opening of the drying cylinder 8 tilt downward, the motor 5 is started to drive the drying cylinder 8 to rotate, and the soft capsules will fall out under the action of gravity and the drying cylinder 8, thus realizing the operation of automatic feeding;

[0031] The hot air flow output by the hot air blower 11 will gush out concentratedly from the gap between the wind shield 15 and the inner wall of the drying cylinder 8. The narrow space improves the thrust of the air flow and pushes the soft capsules away from the wind shield 15. During the process of the soft capsules moving up and down inside the drying cylinder 8, the wind shield 15 can play a role in blocking to prevent the soft capsules from entering the conical sleeve 16. The drying cylinder 8 rotates, driving the carrying plate 12 to move, and the carrying plate 12 drives the soft capsules to move along the inner wall of the drying cylinder 8. When the soft capsules move to a certain height under the action of the carrying plate 12, they will fall to the bottom of the drying cylinder 8 under the action of gravity, thus increasing the degree of up and down movement of the soft capsules, making the air flow more likely to contact the surface of the soft capsules, and thus improving the efficiency of heat exchange. After the hot air flow output by the hot air blower 11 passes through the drying cylinder 8, it enters the heating pipe 14 through the ventilation port on the cylinder cover 13, and the drying cylinder 8 is heated secondarily through the heating pipe 14 surrounding the outside of the drying cylinder 8, so as to utilize the hot air flow secondarily, improve the utilization rate of the hot air flow, and ensure the drying effect.

[0032] The above has described an embodiment of the present invention in detail, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
