[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0017] Refer to the attached Figure 1-3 As shown, a rotary reversing mechanism is used in conjunction with a paper holder conveying mechanism to rotate the pasted paper holder 180° and reverse the direction, comprising a swing cylinder 1, a mounting seat 2, a coupling 3, a support frame 4, a reversing frame 5 and a limit assembly.

[0018] The support frame 4 is a frame structure, and a support plate is provided on the top of the support frame 4, and the mounting seat 2 is fixed on the support plate, and the swing cylinder 1 is fixed on the upper surface of the mounting seat 2. The output shaft of the swing cylinder 1 passes through the mounting seat 2 downward and is connected to the upper end of the coupling 3 in the mounting seat 2. The lower end of the coupling 3 is connected to the rotating shaft passing through the support plate, and the rotating shaft is fixed on the top of the reversing frame 5. When the swing cylinder 1 rotates and swings, the torque is transmitted to the rotating shaft through the coupling 3, and the reversing frame 5 is driven by the rotating shaft to rotate synchronously.

[0019] The bottom and one of the side openings of the reversing frame 5 are open to facilitate the paper support of the conveyor to enter the reversing frame. In order to facilitate the smooth entry of the paper support, a guide plate 6 is provided on both sides of the side opening of the reversing frame 5. The guide plates 6 on both sides form an outwardly flared trumpet mouth, so that even if the position of the paper support on the conveyor is offset, it will be guided into the reversing frame 5 by the guide plate 6.

[0020] The limiting assembly is mainly used to limit the rotation range of the reversing frame 5, and the limiting assembly includes a limiting plate 7 fixed on the top of the support frame 4 and a baffle 8 fixed on the top of the reversing frame 5. The limiting plate 7 is fixed to the lower surface of the support plate on the top of the support frame 4, and two limiting plates 7 are arranged on the circular track of the baffle 8 rotation, and the central angle of the two limiting plates 7 is 180°.

[0021] During the process of the swing cylinder 1 driving the reversing frame 5 to rotate, when the baffle plate 8 contacts the limit plate 7 , it means that the reversing frame 5 has rotated into place.

[0022] Furthermore, in order to prevent the baffle plate 8 from colliding with the limit plate 7 and causing damage to the swing cylinder 1, a buffer and a limit bolt 9 are also provided on the limit plate 7. The length of the limit bolt 9 is less than the length of the buffer in the natural state, so that the buffer can first contact the baffle plate 8 to play a role of deceleration and buffering. The limit bolt 9 is used to contact the baffle plate 8 to stop the rotation and reversing. Preferably, the buffer is a hydraulic buffer 10.

[0023] As another embodiment, bolts may also be installed on the baffle plate 8 for docking with the limiting bolts 9 .

[0024] When the utility model is in use, the paper support is transported along the conveyor into the reversing frame 5, and then the swing cylinder 1 is started to drive the reversing frame 5 and the paper support therein to rotate 180°. When approaching the end of the rotation, the baffle 8 first contacts the hydraulic buffer 10 to buffer and decelerate until the baffle 8 contacts the limit bolt 9 on the limit plate 7, completing a rotation reversal of the paper support. The reversed paper support is continuously transported by the conveyor to the next process direction.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
