[0022] The first transmission roller bed 1 and the second transmission roller bed 2 are provided with first transmission belt connecting assembly 13 on one side, and all transmission rollers in the first transmission roller bed 1 and the second transmission roller bed 2 are drivenly connected together through the first transmission belt connecting assembly 13, so that the transmission rollers in the first transmission roller bed 1 and the second transmission roller bed 2 can rotate synchronously.

[0023] The middle transmission roller of the second transmission roller bed 2 is provided with a notch 15, such as Figure 2 、 Figure 3 、 Figure 4As shown, the middle part of the transmission rollers in the second transmission roller 2 of the device is provided with a notch 15, and the purpose of the notch 15 is to facilitate the movement of the second clamping plate 12 in the clamping mechanism; so that the second clamping plate 12 can clamp the lower box 3, and in cooperation with the first clamping plate 11, the lower box 3 can be firmly fixed on the upper end of the second transmission roller 2.

[0024] The second transmission roller 2 is provided with a second transmission belt connecting assembly 14 away from the side of the first transmission belt connecting assembly 13. Since the middle part of the second transmission roller 2 is provided with a notch 15, it is set for breaking, at this time, in order to ensure that the transmission rollers in the second transmission roller 2 can rotate synchronously, the second transmission belt connecting assembly 14 is needed to link the transmission rollers on both sides together.

[0025] The fixing frame 5 is X-shaped, and the fixing frame 5 of the device needs to be X-shaped, so as to avoid interfering with the movement of the first clamping plate 11 and the second clamping plate 12. Figure 3

[0026] The second clamping plate 12 is U-shaped, and the second clamping plate 12 of the device needs to be U-shaped to avoid movement interference between the second clamping plate 12 and the transmission rollers in the second transmission roller 2.

[0027] Working principle: when using the device, the device transmits the lower box 3 to the upper end of the second transmission roller 2 through the first transmission roller 1, at this time, as long as the lower box 3 is transmitted to the middle part of the second transmission roller 2, it can have a certain inclination angle, such as Figure 1 、 Figure 2 ​As shown, when the box needs to be closed, the lower box 3 is fixed first, the second transfer roller 2 and the lower box 3 are retracted by the hydraulic cylinder 6, and finally the lower box 3 is moved to the rectangular interval surrounded by the first clamping plate 11 and the second clamping plate 12. At this time, the lower box 3 can be angle-corrected and clamped and fixed by the clamping mechanism even if it is inclined. The first electric push rod 9 is elongated first during clamping, so that the lower box 3 can be clamped and fixed left and right by the first clamping plate 11. At this time, the first clamping plate 11 of the device is in a clamping state, so that the lower box 3 can be righted and clamped and fixed. Then the second electric push rod 10 is elongated, so that the lower box 3 can be clamped and fixed front and back by the second clamping plate 12. In this way, the lower box 3 can be clamped and fixed to facilitate subsequent closing work. The up-and-down floating of the second transfer roller 2 can conveniently and quickly clamp and fix the lower box 3 accurately and stably, and also has a certain correction and repair function. Even if the lower box 3 is inclined when it is transferred, the device can still right and stably clamp and fix the lower box 3. It should be noted that after the clamping mechanism of the device clamps and fixes the lower box 3, the first electric push rod 9 and the second electric push rod 10 are at the maximum elongation length, so that the lower box 3 can be fixed at the same position each time to facilitate subsequent closing work. The closing structure can adopt the closing structure in the comparative patent, and the upper box can be clamped by the clamping jaw for subsequent upper and lower box 3 closing.
