Figure 1 - Figure 5 As shown, first, when the object is transferred to the vicinity of the guide plate 208, the two guide plates 208 act on the object at the same time, so that the position of the object can be corrected to avoid deviation during sealing, and then the driving motor 102 is started to drive the first roller 103 to rotate, so that the first turntable 104 rotates forward, and at the same time, the guide rod 108 is used to limit the first support plate 107, so that the rotation force of the first turntable 104 is converted into a force for the first support plate 107 to move left and right in the horizontal direction, which can drive the second rubber clamping plate 118 to move left and right;

[0038] Secondly, by utilizing the meshing action between the driving wheel 109 and the driven wheel 110, the second rotating disk 112 is driven to rotate in the opposite direction at the same time, which can drive the first rubber clamping plate 116 to move left and right on the guide rod 108. By utilizing the first rubber clamping plate 116 and the second rubber clamping plate 118 to move toward or away from each other at the same time, the object can be clamped or released.

[0039] Finally, when the guide plate 208 needs to be replaced, first use a wrench to drive the bolt 207 to rotate, and use the threaded action between the bolt 207 and the first clamp block 204 to drive the first clamp block 204 to rotate, and use the meshing action between the first clamp block 205 and the screw 202 to drive the first clamp block 204 to move in the fixed seat 201, thereby releasing the limit of the guide plate 208 by the first clamp block 204. The working process of the second clamp block 206 is consistent with that of the first clamp block 204, and the guide plate 208 can be disassembled, and the guide plate 208 is installed, and vice versa.
