[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Depend on Figures 1-7 The present invention includes a drying cylinder 1, a hot air conveying mechanism for drying short fibers inside the drying cylinder 1 is installed on the outer wall of the drying cylinder 1, and a storage assembly for placing short fibers is movably installed inside the drying cylinder 1. The storage assembly includes two sets of mounting plates 3, and a storage frame 31 for storing short fibers is fixedly connected to one side of the two sets of mounting plates 3. A pressure plate 32 that engages with the storage frame 31 is rotatably connected to the upper end of the two sets of mounting plates 3 for limiting the position of the short fibers. A mounting block 4 is fixedly connected to one side surface of the storage frame 31. A locking mechanism for locking the pressure plate 32 is installed at the top of the mounting block 4. The locking mechanism includes two sets of insert rods 43 for fixing the pressure plate 32 (the end section of the insert rod 43 is inclined. When the slot 33 is fastened to the mounting block 4, the insert rod 43 will be squeezed. When the mounting block 4 is fully fastened to the slot 33, the insert rod 43 just passes through the inner wall of the insertion hole 34 and fixes the pressure plate 32). A spring 46 is fixedly connected to one side surface of the two sets of insert rods 43 and is fixedly connected to the inside of the mounting block 4. The spring 46 can drive the insert rod 43 to reset, thereby facilitating the fixing of the pressure plate 32.

[0018] Two sets of fixing blocks 42 are symmetrically provided at the top of the mounting block 4. A pinch block 44 that fits into the inner wall of the through groove 41 is fixedly connected to the outer wall of the insertion rod 43. Two sets of fixing blocks 42 are fixedly connected inside the mounting block 4. A limiting block 45 is fixedly connected to the side of the outer wall of the insertion rod 43 away from the pinch block 44. A limiting groove matching the limiting block 45 is provided on the surface of the fixing block 42. The insertion rod 43 can move parallel by the mutual cooperation of the limiting block 45 and the limiting groove, so as to facilitate precise insertion into the insertion hole 34.

[0019] The pressure plate 32 has a slot 33 on one side surface that matches the mounting block 4. By engaging the slot 33 with the mounting block 4, the insertion rod 43 can be positioned. Both ends of the inner wall of the slot 33 have insertion holes 34 that match the insertion rod 43. When it is necessary to dry the short fibers, first open the buckle 14 to release the lock between the cover plate 2 and the drying cylinder 1. Pull the cover plate 2 with the handle 21 to move it and pull the storage assembly out of the drying cylinder 1. By pinching the two sets of pinch blocks 44, the pinch blocks 44 drive the two sets of insert rods 43 to move and separate the insert rods 43 from the insertion holes 34, thus separating the pressure plate 32 from the storage frame 31. After putting the short fibers into the storage frame 31, close the pressure plate 32 and the storage frame 31 again. Pinch the two sets of pinch blocks 44 to engage the slot 33 with the mounting block 4. Release the pinch blocks 44, and the pinch blocks 44 will reset under the action of the spring 46 and be reinserted into the insertion holes 34 to fix the pressure plate 32. Repeat the above operation to put the short fibers into another set of storage frames 31 to dry the short fibers.

[0020] A handle 21 is fixedly installed on the outer surface of the cover plate 2. A positioning rod 15 is rotatably connected to the end of the inner wall of the drying cylinder 1. A positioning groove 25 matching the positioning rod 15 is opened at the end of the transmission rod 24 away from the cover plate 2 for positioning the transmission rod 24. Servo motors 22 are fixedly connected to both sides of the cover plate 2 on both sides of the handle 21 (after each operation of the servo motor 22, the transmission rod 24 drives the material storage component to be in a parallel state, which is convenient for subsequent operations). The output end of the servo motor 22 extends into the interior of the drying cylinder 1 and is connected to the transmission rod 24 through a coupling. Two sets of buckles 14 for locking the cover plate 2 are symmetrically fixedly installed on the outer wall of one end of the drying cylinder 1 (the buckles 14 are used to limit the cover plate 2, which is existing technology and will not be described in detail here).

[0021] A cover plate 2 is movably installed at one end of the drying cylinder 1. A tumbling mechanism is installed on the surface of the cover plate 2 to drive the storage component to rotate. The tumbling mechanism drives the storage component to rotate inside the drying cylinder 1, which facilitates uniform drying of short fibers. The tumbling mechanism includes a transmission rod 24 that drives the storage component to rotate. The storage component is symmetrically installed on the outer wall of the transmission rod 24. The transmission rod 24 drives the storage component to rotate. Four sets of fixing rods 26 are symmetrically fixedly connected to both ends of the two sets of mounting plates 3 on the outer wall of the transmission rod 24. A support block 27 is fixedly connected to one end of each of the four sets of fixing rods 26. A ball bearing 28 that drives the storage component to roll inside the drying cylinder 1 is embedded on one side of the support block 27.

[0022] After placing the short fibers inside the storage frame 31, the storage assembly is pushed into the drying cylinder 1. The transmission rod 24 and the storage assembly are supported by the fixing rod 26 and the support block 27. The ball bearing 28 facilitates the movement of the storage assembly and also provides positioning. When the storage assembly is fully inside the drying cylinder 1, the positioning rod 15 is inserted into the positioning groove 25 on the transmission rod 24 (the positioning rod 15 is a spline shaft design, and the positioning groove 25 is a spline groove, so the positioning rod 15 and the positioning groove 25 can mesh). When the cover plate 2 contacts the drying cylinder 1, the cover plate 2 is locked by rotating the buckle 14 (the cover plate 2 and the drying cylinder 1 are sealed). The servo motor 22 is started, and the servo motor 22, together with the transmission rod 24, drives the storage assembly to rotate inside the drying cylinder 1 to dry the short fibers.

[0023] The hot air conveying mechanism includes three sets of fixed pipes 12 equidistantly connected to the outer wall of the drying cylinder 1. A connecting pipe 121 is fixedly connected between the ends of the three sets of fixed pipes 12. A conveying pipe 13 connected to an external hot air device (which includes a fan and a heating element) is fixedly connected to the outer wall of the connecting pipe 121. Multiple through holes 16 connected to the fixed pipes 12 are opened on the surface of the drying cylinder 1. The conveying pipe 13 transmits hot air through the through holes 16 to the inside of the drying cylinder 1 via the connecting pipe 121 and the fixed pipes 12 to dry the short fibers. An exhaust pipe 11 is vertically fixedly connected to the outer wall of the drying cylinder 1. A one-way valve for venting gas is installed inside the exhaust pipe 11 to prevent the water vapor generated inside the drying cylinder 1 after the short fibers are dried from being unable to be discharged, which could lead to excessive internal pressure and safety hazards.

[0024] When the material storage assembly rotates inside the drying cylinder 1 driven by the tumbling mechanism, the external hot air equipment is activated (this is existing technology and will not be described in detail here). The hot air enters the connecting pipe 121 through the conveying pipe 13, and then is transmitted to the three sets of fixed pipes 12 through the connecting pipe 121. Then, it is input into the drying cylinder 1 through the through hole 16 to dry the short fibers inside the material storage frame 31. During the drying process, when the air pressure inside the drying cylinder 1 is too high, the gas is discharged through the one-way valve installed inside the air outlet pipe 11, thereby reducing safety hazards to a certain extent.

[0025] A first support plate 17 is fixedly connected to the outer wall of the drying cylinder 1 to support it. A second support plate 18 is fixedly connected to one end of the first support plate 17. A dovetail groove 19 is opened on the upper surface of the second support plate 18. A dovetail block 23 that matches the dovetail groove 19 is fixedly connected to the outer wall of the cover plate 2. During the movement of the cover plate 2, the dovetail block 23 and the dovetail groove 19 cooperate with each other to make the cover plate 2 only able to move in parallel. After the short fibers are dried, release the lock on the cover plate 2, move the cover plate 2 by pulling the handle 21, pull the storage component out from inside the drying cylinder 1, open the pressure plate 32, and the dried short fibers can be taken out.

[0026] Working principle: First, open the buckle 14 to release the lock of the cover plate 2. Separate the cover plate 2 from the drying cylinder 1 using the handle 21. Pull the material storage component out from inside the drying cylinder 1. Pinch the two sets of pinch blocks 44 to separate the insertion rod 43 from the insertion hole 34, thus opening the material storage frame 31. Place the short fibers to be dried into the material storage frame 31, then cover the material storage frame 31 with the pressure plate 32. Snap the slot 33 onto the outer wall of the mounting block 4. The elastic force of the spring 46 drives the insertion rod 43 to reset, thus facilitating the fixation of the pressure plate 32. Then, push the limited material storage component back into the drying cylinder 1. The material storage component is supported by the fixing rod 26 and the support block 27. The ball bearing 28 facilitates the movement of the material storage component inside the drying cylinder 1. When the positioning rod 15 inserts... When the cover plate 2 reaches the inner wall of the positioning groove 25 on the transmission rod 24, it is connected to the drying cylinder 1. The cover plate 2 is fixed by the buckle 14. Then the servo motor 22 is started. The servo motor 22 drives the transmission rod 24 to rotate. Under the action of the transmission rod 24, the storage component flips inside the drying cylinder 1. Then the external hot air equipment is started. The hot air is transmitted to the connecting pipe 121 through the conveying pipe 13. Then the hot air is delivered to the inside of the drying cylinder 1 through the fixing pipe 12 and the through hole 16 to dry the short fibers inside the storage frame 31. When the pressure inside the drying cylinder 1 is too high, the water vapor generated during drying is discharged through the one-way valve inside the air outlet pipe 11. After drying is completed, the storage component is pulled out from the inside of the drying cylinder 1 to collect the dried short fibers.
