The described embodiments are part of the embodiments of the utility model, not all of the embodiments.
[0030] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.
[0031] Embodiment 1:
[0032] Please refer to Figure 1 and Figure 2The utility model discloses a rotary unloading structure, comprising: push subassembly 1, with the parallel setting of sliding difference shaft 102, including drive mechanism 11 and guide rail base 12, and drive mechanism 11's drive end 13 sets up on guide rail base 12, and can along guide rail base 12 relative sliding;Guide rail base 12 is along the length direction respectively provided with initial area 121 and unloading area 122, and sliding difference shaft 102 is opposite to unloading area 122;And unloading subassembly 2 are connected with drive mechanism 11's drive end 13, including the unloading support arm 23 of sequentially connected, rotary arm 22 and unloading push arm 21;Unloading support arm 23 is connected with rotary arm 22 between rotation, and rotary arm 22 extends along the length direction of guide rail base 12 and sets up;Wherein, drive mechanism 11's drive end 13 is located in initial area 121, and unloading push arm 21 extends to unloading area 122 through rotary arm 22, and can rotate to be close to sliding difference shaft 102.
[0033] Specifically, the rotary unloading structure includes a push subassembly 1 and an unloading subassembly 2. The push subassembly 1 includes a guide rail base 12, and the guide rail base 12 is internally provided with a drive mechanism 11 for providing power driving. The drive mechanism 11 can be selected but is not limited to an electric drive mechanism 11. The drive end 13 of the drive mechanism 11 is arranged on the guide rail base 12 and can move back and forth along the guide rail base 12. The guide rail base 12 is divided into an initial area 121 and an unloading area 122 by a wall plate 101 of an external structure. A sliding difference shaft 102 for bearing a roll of material is arranged on the wall plate 101, and the sliding difference shaft 102 is opposite to the unloading area 122. The unloading subassembly 2 is connected to the drive mechanism 11 through the drive end 13. The unloading subassembly 2 includes, in sequence from top to bottom, an unloading support arm 23, a rotary arm 22, and an unloading push arm 21. The rotary arm 22 is rotationally connected to the unloading support arm 23. The unloading support arm is used to be fixed on the drive end 13. The unloading push arm 21 is used to be in contact with the roll of material and is driven to rotate by the rotary arm 22, so as to realize the swinging of the unloading push arm 21. The rotary arm 22 is arranged in extension along the length direction of the guide rail base 12, so that the unloading support arm 23 and the unloading push arm 21 are staggered. When the rotary unloading structure is in a state of stopping unloading, the drive end 13 of the drive mechanism 11 is located in the initial area 121, and the unloading push arm 21 extends to the unloading area 122 through the rotary arm 22 and can be rotated to swing close to the sliding difference shaft 102. Because the rotary arm 22 extends the unloading push arm 21, the unloading push arm 21 can be longer than the sliding difference shaft 102 during unloading, so that the push subassembly 1 does not have to protrude from the sliding difference shaft 102 and can be arranged in the wall plate 101. The rotary unloading structure can retract the unloading subassembly 2 to the initial area 121 inside the wall plate 101 when stopping unloading.
[0034] In use, the unloading pushing arm 21 is fixed and rotated by the rotating arm 22 to achieve swinging, so that the unloading pushing arm 21 swings to the slip shaft 102 and is placed on the back of the roll, and then the driving mechanism 11 on the pushing assembly 1 is used to drive the driving end 13 on the guide rail base 12 to move outward along the guide rail, so that the unloading assembly 2 on the driving end 13 is moved, and the unloading pushing arm 21 pushes the roll out of the slip shaft 102.
[0035] In the embodiment, the unloading assembly 2 used to abut against the roll is divided into three structures, the unloading supporting arm 23, the rotating arm 22 and the unloading pushing arm 21. The rotating arm 22 is designed to prolong the unloading distance and is transmitted to the unloading pushing arm 21 to achieve swinging. The unloading assembly 2 is moved by the driving end 13 of the driving mechanism 11, so that the unloading action is completed. Compared with the traditional unloading structure, the rotating arm 22 cannot be retracted to the inside of the wall plate 101, which is easy to cause safety hazards. The design of the rotating arm 22 can reduce the occupied space of the pushing assembly 1. The swinging of the unloading pushing arm 21 realizes the extension and retraction of the unloading assembly 2 as a whole, avoiding the interference of the unloading assembly 2 with the movement of other components. When the unloading is stopped, the driving end 13 is moved to the initial area 121, and part of the structure is hidden in the wall plate 101, so that the whole unloading structure occupies a smaller space.
[0036] Embodiment 2:

It can be understood that the pushing plate 212 can be replaced according to different unloading requirements, so as to realize adaptation and facilitate adjustment of technicians during later maintenance.
[0050] The rotating unloading structure of the utility model, through the rotating arm 22, the originally used unloading assembly 2 is lengthened, so that the pushing assembly 1 can also realize the unloading action without protruding the material roll, thereby reducing the space occupied by the overall structure.
