Specifically, the adjusting assembly 4 includes a rotating member, an adjusting member 430, and a holding member 440.

In this embodiment, the holding member 440 has a strip structure, so that the holding member can be conveniently held by a worker and can be adjusted and rotated more conveniently. One end of the rotating member is rotatably disposed on the mounting member 210 and is fixedly connected to the holding member 440; the other end of the first supporting member extends to the lower part of the first supporting member 310.

Specifically, the lower end surfaces of the mounting member 210 and the auxiliary supporting member 240 are provided with fixing members 250, the two fixing members 250 are respectively located at the centers of the mounting member 210 and the auxiliary supporting member 240, and the two fixing members 250 are provided with through holes, and the central line axes of the two through holes coincide with each other. The rotating member includes a second rotating shaft 410 and a third rotating shaft 420, the second rotating shaft 410 is a hollow structure, and two ends of the second rotating shaft are respectively and fixedly sleeved in the two through holes.

Meanwhile, the third rotating shaft 420 is rotatably sleeved in the cavity of the second rotating shaft 410, and one end of the third rotating shaft 420 passes through the through hole formed in the fixing member 250 of the mounting member 210 and penetrates through the first end surface 110 of the housing 1 to be fixedly connected with the holding member 440, and the other end thereof passes through the through hole formed in the fixing member 250 of the auxiliary supporting member 240 and is fixedly connected with the adjusting member 430.

With continued reference to fig. 4-5, the second rotating shaft 410 is provided with an arc-shaped rotating guide slot 411, and the structure of the rotating guide slot 411 can be set according to the actual rotating angle. And a rotating guide member 421 is arranged on the third rotating shaft 420, the rotating guide member 421 is arranged opposite to the rotating guide slot 411, and the rotating guide slot 411 is slidably arranged in the rotating guide slot 411 and can slide back and forth along the arc of the rotating guide slot 411. Meanwhile, the mounting member 210 is further provided with a locking member 260, specifically, the locking member 260 includes a first end portion and a second end portion, the first end portion is slidably disposed on the upper end surface of the mounting member, and the second end portion extends to the third rotating shaft 420. The second end of the locking member 260 is provided with a screw hole, and one end of the third rotating shaft 420 is provided with a screw, whereby the locking member 260 is screw-coupled with the third rotating shaft. And the third rotating shaft 420 passes through the threaded hole and is coupled to the grip 440. Since the locking member 260 is threadedly coupled to the third rotating shaft 420, i.e., a screw-nut pair structure is formed, the rotation of the third rotating shaft 420 can be converted into the linear motion of the locking member 260, i.e., the locking member 260 can move back and forth along the axial direction of the third rotating shaft 420 as the third rotating shaft 420 rotates. Therefore, when the grip 440 is rotated under the guiding action of the rotation guide slot 411 and the rotation guide 421, the third rotation shaft 420 drives the locking member 260 to move back and forth along the axial direction of the rotation shaft. Therefore, when the unloading is completed, the holding member 440 is rotated, so that the third rotating shaft 420 drives the locking member 260 to move close to the carrier 3, and the locking member is clamped at the upper end surface of the carrier 3, that is, the locking member 260 clamps the carrier 3, and the carrier 3 is restricted from rotating downward. This has the effect of locking the carrier 3, so that the carrier 3 is more stable when containing material. When the material needs to be unloaded, the holding member 440 is rotated, so that the third rotating shaft 420 drives the locking member 260 to move away from the carrier 3, that is, the locking member 260 is separated from the carrier 3, thereby releasing the locking of the locking member 260 on the carrier 3, and enabling the carrier 3 to rotate freely.

Further, the adjusting member 430 is vertically disposed on the third rotating shaft 420, that is, one end of the adjusting member 430 is fixed on the third rotating shaft 420, and the other end thereof extends in a direction perpendicular to the axis of the third rotating shaft 420. The adjusting member 430 is located below the first supporting member 310 and is spaced apart from the first rotating shaft 330. When the third rotating shaft 420 is rotated, the adjusting member 430 is rotated to a direction toward the first carrier 310, and the first carrier 310 can be pushed to rotate downward, so that the entire carrier 3 is inclined downward, so that the material is moved downward by inertia, thereby being discharged.

In order to further limit the angle of rotation of the carrier 3, a limit stop 10 is also provided. Specifically, one end of the limiting member 10 is fixed to the first supporting arm 220, and the other end thereof is fixed to the second supporting arm 230. The limiting member 10 is disposed corresponding to the first rotating shaft 330, and is located below the first rotating shaft 330. Through setting up this structure, can prevent among the adjustment process, the turned angle who holds carrier 3 is too big, leads to the material falling speed too fast and leads to the material to be damaged.

As shown in fig. 6, a magnetic assembly 7 is further disposed on one side of the adjusting member 430, the magnetic assembly 7 includes a magnetic base 710 and two ferromagnetic magnets 720, the magnetic base 710 is disposed on one side of the adjusting member 430 and is mounted on the limiting member 10, the two ferromagnetic magnets 720 are fixedly disposed on the magnetic base 710, and when the adjusting member 430 rotates to the horizontal position, the adjusting member 430 can contact with the ferromagnetic magnets 720. The adjusting piece 430 is of a metal structure in the embodiment, after the discharging is completed, a worker only needs to loosen the holding piece 440, and the adjusting piece 430 can be automatically attracted to the magnet under the action of strong magnetism, so that the bearing piece 3 is restored to the initial state.

Through above supporting frame 2, hold carrier 3, mutual supporting between the regulating assembly 4, when the material is in the in-process of transportation, because of when no exogenic action, hold carrier 3 and can be used for placing the material through flange 311 structure overlap joint on two support arms, make from this that hold carrier 3 is in the horizontality. When the material needs to be unloaded, make regulating part 430 rotate to the below of first carrier 310 through rotating holding member 440, make carrier 3 rotate downwards under the effect of regulating part 430, bear the terminal surface downward sloping promptly, make the material unloaded automatically from this, and need not the manual work and carry the unloading, solved among the prior art technical problem that the pay-off tray still needs the manual work to unload.

For a clearer explanation of the present application, the working principle of the present invention is further explained below by taking the embodiment shown in fig. 1 to 6 as an example:

when the material is conveyed to the discharging position through the feeding device, at this time, the worker rotates the adjusting assembly 4, namely, the third rotating shaft 420 is rotated by rotating the holding piece 440, under the rotating action of the third rotating shaft 420, the adjusting piece 430 is rotated to the first bearing piece 310, and the upper end part of the first bearing piece 310 is lifted, so that the whole bearing piece 3 rotates downwards, a bearing end surface inclined downwards is formed, the material moves downwards under the action of inertia, and the discharging operation is completed. When the unloading is finished, the worker only needs to loosen the holding part, so that the adjusting piece 430 rotates to the magnetic assembly 7 and is in a horizontal state under the action of the magnetic assembly 7. Make from this to hold carrier 3 and rotate to horizontal position, namely make material feeding unit resume to initial condition, from this, through above structure, need not artifical transport and can accomplish and unload, solved the technical problem that the pay-off tray still needs the manual work to unload among the prior art, reduced the human labor, effectual production efficiency that has improved has reduced the cost of production.
