SPECIFIC IMPLEMENTATION MODE
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a drying device for the production of paracetamol, comprising a base 1, a drying cylinder 2 arranged above the middle of the base 1, a drying layer 3 arranged inside the drying cylinder 2, a reciprocating mechanism 4 arranged above one side of the base 1, and a rotating mechanism 5 arranged above the reciprocating mechanism 4;
[0021] The reciprocating mechanism 4 includes a motor 401 fixedly connected above one side of the base 1, a first rotating shaft 402 fixedly connected to the output end of the motor 401, a first connecting plate 403 fixedly connected to the upper end of the first rotating shaft 402, a second connecting plate 414 arranged above the first connecting plate 403, a first guiding hole 404 arranged inside the second connecting plate 414, a first guiding rod 405 arranged inside the first guiding hole 404. The external structure of the first guiding hole 404 is a horizontal straight line, and the matching mode of the first guiding hole 404 and the first guiding rod 405 is clearance fit, so that when the first guiding rod 405 rotates inside the first guiding hole 404, it can drive the second connecting plate 414 to perform reciprocating motion. A third connecting plate 406 is arranged on the side of the second connecting plate 414 close to the drying cylinder 2. First supporting plates 407 are arranged on both sides of the drying cylinder 2. The connection mode of the first supporting plates 407 and the base 1 is fixed connection. A first groove 408 is arranged inside the first supporting plates 407, a second supporting plate 409 is arranged inside the first groove 408. The external structure of the second supporting plate 409 is a cuboid, and the central axis of the second supporting plate 409 coincides with the central axis of the first supporting plate 407, so that the second supporting plate 409 will not rotate when moving up and down inside the first supporting plate 407. A second guiding hole 410 is opened on the inner wall of the first groove 408 close to the motor 401 side. A fourth connecting plate 411 is horizontally slidably connected to the outside of the first supporting plate 407. A third guiding hole 412 is arranged inside the fourth connecting plate 411, a second guiding rod 413 is arranged inside the third guiding hole 412. The connection mode of the second guiding rod 413 and the second supporting plate 409 is fixed connection. The connection mode of the fourth connecting plate 411 and the third connecting plate 406 is fixed connection. The external structure shape of the third guiding hole 412 is an inclined straight line, and the matching mode of the third guiding hole 412 and the second guiding rod 413 is clearance fit, so that when the third guiding hole 412 moves left and right, it can drive the second guiding rod 413 to move up and down.
[0022] The interior of the second support plate 409 is provided with a second groove 6. The rotating mechanism 5 includes a third support plate 501 rotatably connected to the inner side of the second groove 6. The inner side of the third support plate 501 is rotatably connected to a second rotating rod 502. The second rotating rod 502 is fixedly connected to the drying cylinder 2. The inner side of the second rotating rod 502 is provided with a third groove 503. A guiding groove 504 communicates with the inner wall of the third groove 503. A third guiding rod 505 is arranged inside the guiding groove 504. A push rod 506 is arranged inside the third groove 503. Above the third connecting plate 406, there is a fourth support plate 507. The inner side of the fourth support plate 507 is provided with a fourth groove 508. Inside the fourth groove 508, there is a fifth support plate 509. The fifth support plate 509 is rotatably connected to the push rod 506. The external structural shape of the guiding groove 504 is spiral, and the guiding groove 504 and the third guiding rod 505 are in clearance fit, so that when the third guiding rod 505 moves horizontally inside the guiding groove 504, it can drive the second rotating rod 502 to rotate. The external structural shape of the push rod 506 is cylindrical, and the outer side surface of the push rod 506 fits with the inner side surface of the third groove 503, so that the push rod 506 will not rotate when rotating inside the third groove 503.
[0023] When drying paracetamol, when the motor 401 is started to drive the first rotating shaft 402 and the first connecting plate 403 to rotate, the first guiding rod 405 rotates inside the first guiding hole 404, pushing the second connecting plate 414 and the third connecting plate 406 to move reciprocally. Since the fourth connecting plate 411 is fixedly connected to the third connecting plate 406, the fourth connecting plate 411 moves reciprocally. Since the external structural shape of the third guiding hole 412 is an inclined straight line, and the third guiding hole 412 and the second guiding rod 413 are in clearance fit, the second guiding rod 413 and the second support plate 409 move up and down, driving the third support plate 501 to move. Since the second rotating rod 502 is rotatably connected to the third support plate 501, the whole drying cylinder 2 tilts, causing the paracetamol inside the drying cylinder 2 to shake, increasing the probability that the paracetamol in the middle approaches the drying layer 3 and improving the drying efficiency.
[0024] During the left - right movement of the second connecting plate 414, it drives the fourth support plate 507 and the fifth support plate 509 to reciprocate, drives the push rod 506 rotatably connected to the fifth support plate 509 to reciprocate, so that the push rod 506 drives the third guide rod 505 to reciprocate. Since the external structural shape of the guide groove 504 is spiral and the cooperation mode between the guide groove 504 and the third guide rod 505 is clearance fit, the second rotating rod 502 rotates, driving the whole drying cylinder 2 to rotate, and the acetaminophen inside the drying cylinder 2 rotates, increasing the probability that the acetaminophen in the middle approaches the drying layer 3 and improving the drying efficiency.
