The fixing assembly 20 includes a first blocking plate 22, and the first blocking plate 22 is sleeved outside the rotating shaft 10 and rotates synchronously with the rotating shaft 10. The sliding assembly 30 includes a second catch plate 31 and an operating member 32. The second blocking disc 31 is sleeved outside the rotating shaft 10 and is movable along the axial direction of the rotating shaft 10. A fixing position a for fixing the tray 100 is formed between the second retainer 31 and the first retainer 22. The operating member 32 is disposed on the second blocking plate 31, and the operating member 32 is controllably connected to or disconnected from the rotating shaft 10 during the movement of the second blocking plate 31 along the axial direction of the rotating shaft 10.

In the discharging device, the charging tray 100 is installed at the fixed position a between the first blocking tray 22 and the second blocking tray 31, and the charging tray 100 is clamped by the first blocking tray 22 and the second blocking tray 31, so that the charging tray 100 synchronously rotates along with the rotating shaft 10 to discharge. When the tray 100 needs to be replaced, first, the operating member 32 is controlled so that the operating member 32 is separated from the rotating shaft 10, so that the second shutter 31 can be slid out in the axial direction of the rotating shaft 10, and the tray 100 is removed and a new tray 100 is loaded.

The embodiment of the utility model provides an in, fixed subassembly 20 is still including the cover locating the outer fixed axle 21 of rotation axis 10, but fixed axle 21 and rotation axis 10 synchronous rotation, and along rotation axis 10 axial position adjustable. The first blocking disc 22 is sleeved outside the fixing shaft 21 and is fixedly connected with the fixing shaft 21, so that the first blocking disc 22 and the fixing shaft 21 synchronously rotate along with the rotating shaft 10, the first blocking disc 22 can be adjusted in position along with the fixing shaft 21 along the axial direction of the rotating shaft 10, the purpose of adjusting the position of the material disc 100 between the first blocking disc 22 and the second blocking disc 31 is achieved, and accurate material discharging is achieved. Further, the second disc 31 is sleeved outside the fixing shaft 21 and is movable along the axial direction of the fixing shaft 21. The operating member 32 is controllably coupled to or decoupled from the fixed shaft 21 during movement with the second stopper 31 in the axial direction of the fixed shaft 21. Thus, when the operating member 32 is coupled to the fixed shaft 21, the second retaining plate 31 is prevented from moving away from the first retaining plate 22, so as to keep clamping the material tray 100. When the operating member 32 is separated from the fixed shaft 21, the second retaining plate 31 can be moved away from the first retaining plate 22 to remove the second retaining plate 31, so as to replace the tray 100.

In an embodiment, the fixing shaft 21 has a locking portion 211 that can be locked with the operating element 32, so that the operating element 32 can be operated to lock the operating element 32 with the locking portion 211 to prevent the second blocking plate 31 from moving away from the first blocking plate 22.

In an embodiment, the fixing assembly 20 further includes a third elastic member 23 and a locking member 24, and the fixing shaft 21 is movable in the axial direction of the rotating shaft 10. The third elastic element 23 is connected to the fixed shaft 21 and the rotating shaft 10 to provide a pre-tightening force for the fixed shaft 21 to drive the first stopping disc 22 to move close to the second stopping disc 31. The locker 24 is coupled to the rotating shaft 10 and is adjustable in position in the axial direction of the rotating shaft 10. The locking member 24 is used to abut against one end of the fixed shaft 21 to prevent the fixed shaft 21 from driving the first stopping plate 22 to move close to the second stopping plate 31. Thus, under the action of the pre-tightening force provided by the third elastic element 23, the fixing shaft 21 abuts against the locking element 24, so that the position of the fixing shaft 10 and thus the position of the first blocking disc 22 can be adjusted by adjusting the position of the locking element 24 in the axial direction of the rotating shaft 10, and the purpose of adjusting the position of the charging disc 100 between the first blocking disc 22 and the second blocking disc 31 is achieved, so that accurate discharging is achieved. Alternatively, the locker 24 may be a lock nut, and the locker 24 is screw-coupled to the rotary shaft 10 such that the position of the locker 24 in the axial direction of the rotary shaft 10 can be adjusted by rotating the locker 24.

In a specific embodiment, the fixed shaft 21 and the rotation shaft 10 may be coupled by a key 26 so that the fixed shaft 21 and the rotation shaft 10 may rotate synchronously, and the fixed shaft 21 may be movable in the axial direction of the rotation shaft 10 with respect to the rotation shaft 10.

Alternatively, the third elastic member 23 may be a spring.

In an embodiment, the locking member 24 may include a plurality of locking members 24, the plurality of locking members 24 are arranged along the axial direction of the rotating shaft 10, and every two adjacent locking members 24 abut against each other, so as to avoid the problem that the locking members 24 are loosened to cause inaccurate positions of the tray 100.

In one embodiment, the fixing assembly 20 further comprises a stopper 25, wherein the stopper 25 is fixedly connected to the rotating shaft 10 and is located at a side of the locking member 24 facing away from the fixing shaft 21, so that the locking member 24 can be stopped from being separated from the rotating shaft 10 by the stopper 25.

It should be noted that the outer diameter of the locking member 24 is smaller than the inner diameters of the second stopping plate 31 and the sliding sleeve 33, so as to ensure that the sliding sleeve 33 and the second stopping plate 31 can slide along the fixed shaft 21 to be removed (i.e., the sliding sleeve 33 and the second stopping plate 31 are removed) when the operating member 32 is separated from the fixed shaft 21.

In the embodiment of the present invention, the operation member 32 is pivotally connected to the second plate 31, and the operation member 32 can be engaged with the fixing shaft 21 in the process of rotating, so as to prevent the second plate 31 from moving away from the first plate 22 along the axial direction of the fixing shaft 21. Thus, when the material tray 100 needs to be replaced, the operating member 32 is rotated to separate the operating member 32 from the fixed shaft 21, so that the second retaining plate 31 can be removed and the material tray 100 can be replaced with a new material tray. Finally, the second retaining plate 31 is sleeved on the fixing shaft 21, the new tray 100 is clamped tightly, and the operating element 32 is clamped and matched with the fixing shaft 21. That is, the operation member 32 is rotated to realize the engagement or separation of the operation member 32 and the fixed shaft 21, and the operation is stable and reliable, and the operation is convenient and fast.

Further, the sliding assembly 30 further includes a second elastic member 34, and the second elastic member 34 is used for providing a pre-tightening force for rotating the operating member 32 to be in snap fit with the fixed shaft 21. Therefore, after the new material tray 100 is replaced, the second retaining plate 31 is sleeved on the rotating shaft 10, then the second retaining plate 31 is pushed to move towards the first retaining plate 22 until the new material tray 100 is clamped, at this time, the operating element 32 is in clamping fit with the fixed shaft 21 under the action of the pre-tightening force provided by the second elastic element 34, the second retaining plate 31 is prevented from moving in the direction away from the first retaining plate 22, and the new material tray 100 is kept clamped. More specifically, the operating member 32 is pivotally connected to the second plate 31 by a pivot shaft, the second elastic member 34 is disposed on the pivot shaft, and one end of the second elastic member 34 is fixed to the operating member 32, and the other end is fixed to the second plate 31. Preferably, the second elastic member 34 may be a torsion spring.

Further, the operating member 32 can be engaged with the engaging portion 211 of the fixing shaft 10 during rotation, so as to prevent the second blocking plate 31 from moving away from the first blocking plate 22 along the axial direction of the fixing shaft 21. More specifically, the operating element 32 includes opposite pressing ends and a clamping end 322, and the clamping end 322 is used for clamping and matching with the clamping portion 211 on the fixed shaft 21. Under the action of the pre-tightening force provided by the second elastic member 34, the clamping end 322 keeps clamping fit with the clamping portion 211 on the fixing shaft 21. When the pressing end is pressed, the operating element 32 can rotate to the engaging end 322 to separate from the engaging portion 211 by overcoming the pre-tightening force provided by the second elastic element 34. Thus, the operation of replacing the tray 100 is further simplified, and the operation time is saved.

In the embodiment of the present invention, the sliding assembly 30 further includes a sliding sleeve 33 and a first elastic member 36. The sliding sleeve 33 is sleeved outside the fixed shaft 21 and is movable along the axial direction of the fixed shaft 21. The first elastic member 36 is connected to the second shutter 31 and the sliding sleeve 33 to provide a preload force for moving the second shutter 31 relative to the sliding sleeve 33 toward the first shutter 22. The operation member 32 is provided to the slide sleeve 33. Thus, when the second retaining plate 31 and the first retaining plate 22 clamp the material tray 100 and the operating element 32 is connected to the fixed shaft 21, the sliding sleeve 33 compresses the first elastic element 36 to apply a pre-tightening force to the second retaining plate 31, so that the second retaining plate 31 and the first retaining plate 22 always clamp the material tray 100. Alternatively, the first elastic member 36 may be a spring.

In the embodiment, the operating member 32 is pivotally connected to the sliding sleeve 33, that is, the operating member 32 is indirectly pivotally connected to the second stop plate 31 through the sliding sleeve 33.

In a specific embodiment, the operating member 32 may include a plurality (i.e., two or more), and the plurality of operating members 32 are arranged along the circumferential direction of the sliding sleeve 33, so that the second stop 31 is fixed more stably and reliably. It is understood that the fixing shaft 21 is provided with a snap-fit portion 211 corresponding to each operating member 32 so as to be snap-fit with the corresponding operating member 32. Preferably, the operating member 32 may include two operating members 32, and the two operating members 32 are symmetrically disposed on opposite sides of the sliding sleeve 33.

In an embodiment, the sliding sleeve 33 and the second stop disc 31 may be connected by a screw with equal height. The first elastic element 36 is sleeved on the equal-height screw, and two opposite ends of the first elastic element are respectively abutted against the sliding sleeve 33 and the second stop disc 31. Thus, after the operating member 32 is separated from the fixed shaft 21, the sliding sleeve 33 and the second stopper 31 can be removed as a whole for replacing the tray 100, thereby further simplifying the operation of replacing the tray 100 and saving the time for replacing the tray 100. The provision of the contour screws on the one hand limits the range of movement of the second stop disk 31 relative to the sliding sleeve 33 and on the other hand guides the first spring element 36.

In the embodiment, the sliding sleeve 33 is fixedly connected with a limiting rod 35, and the limiting rod 35 is used for limiting the rotation angle of the operating element 32 and preventing the excessive rotation angle of the operating element 32 from influencing the assembly and disassembly of the sliding sleeve 33.

Thus, the discharging device can be installed to the discharging position through the rotary supporting seat 40, so that the discharging operation can be conveniently carried out.

In one embodiment, the rotary support 40 is located on a side of the first stopping disk 22 facing away from the second stopping disk 31, and the sliding sleeve 33 is located on a side of the second stopping disk 31 facing away from the first stopping disk 22.

It will be appreciated that the rotating shaft 10 is coaxial with the fixed shaft 21 (i.e., the axes of the two are collinear), and the first and second retainers 22, 31 are coaxial with the fixed shaft 21 (i.e., the truncated cones B on the first and second retainers 22, 31 are coaxial with the fixed shaft 21).

The process of replacing the tray 100 by the emptying device is described as follows with the attached drawings:

first, the pressing end of the operating element 32 is pressed, so that the catching end 322 of the operating element 32 is separated from the catching portion 211 on the fixed shaft 21. Then, the sliding sleeve 33 and the second shutter 31 are slid out to the right, that is, the sliding sleeve 33 and the second shutter 31 are removed, so that the tray 100 can be removed and a new tray 100 can be loaded. Finally, the second retaining plate 31 and the sliding sleeve 33 are slid into the fixed shaft 21 leftwards, and the new tray 100 is clamped, at this time, the clamping end 322 of the operating member 32 is clamped and matched with the clamping part 211 on the fixed shaft 21 under the action of the second elastic member 34.
