[0033] The guide assembly 4 is used to transport the secondary film to the folding assembly 5;

[0034] The folding assembly 5 is used to fold the two sides of the secondary film toward the middle.

[0035] This embodiment can effectively reduce the space occupied by the folding and unloading device by arranging the secondary film loading component 2 on the two side walls of the main film loading equipment 1. The secondary film loading component 2 loads the secondary film, and the secondary film enters the tension component 3 after leaving the secondary film loading component 2. The distance between the adjusting wheel 32 and the fixed wheel group 31 can be adjusted by the rocker arm 33, thereby adjusting the tension of the secondary film during the transportation process. The guide component 4 guides the secondary film to the folding component 5, and the folding component 5 folds the secondary film.

[0036] like Figure 1~Figure 2 As shown, the auxiliary film loading assembly 2 includes: a first loading tray 21, a second loading tray 22, a first loading shaft and a second loading shaft;

[0037] The first loading tray 21 is located above the second loading tray 22, and the first loading shaft is arranged corresponding to the first loading tray 21.

[0040] The adjusting cylinder 34 is arranged on the main film feeding equipment 1, and the output end of the adjusting cylinder 34 is connected to the rocker rod 33, which is used to adjust the distance between the fixed wheel group 31 and the adjusting balance wheel 32. The fixed wheel group 31 includes: at least two fixed wheels, and the adjusting balance wheel 32 is set according to the number of fixed wheels. The secondary film is alternately wound on the fixed wheel group 31 and the adjusting balance wheel 32.

[0041] The adjusting cylinder 34 can push the rocker arm 33 to rotate, adjust the distance between the fixed wheel group 31 and the adjusting balance wheel 32, and the adjusting balance wheel 32 is set according to the number of fixed wheels. The auxiliary film is wound back and forth on multiple fixed wheels and the adjusting balance wheel 32, which is convenient for adjusting the tension of the auxiliary film.

[0042] like Figure 4 As shown, the guide assembly 4 includes: a guide wheel 41, an adjustment mechanism and a detector 42.

[0043] The adjusting mechanism is arranged on the main film loading equipment 1, and the guide wheel 41 is arranged at the output end of the adjusting mechanism. The guide wheel 41 is used to change the conveying direction of the secondary film. The detector 42 is arranged on one side of the adjusting mechanism and is used to detect the conveying direction of the secondary film after passing through the guide wheel 41. The adjusting mechanism adjusts the position of the guide wheel 41 according to the detection result of the detector 42.

[0044] In this embodiment, the guide wheel 41 is tilted, and the secondary film can change direction by 90° after passing through the guide wheel 41. The changing angle of the secondary film can be adjusted by adjusting the tilt angle of the guide wheel 41. The detector 42 detects the conveying status of the secondary film after the guide wheel 41 changes direction. When the detector 42 detects that the secondary film is not conveyed in a specific direction, the adjustment mechanism adjusts the position of the guide wheel 41, thereby changing the conveying direction of the secondary film.

[0045] like Figure 4 As shown, the adjustment mechanism includes: an adjustment frame 43, an adjustment motor 44 and an adjustment screw 45;

[0046] The adjusting frame 43 is fixed on the main film feeding device 1 , and the adjusting motor 44 is arranged on one side of the adjusting frame 43 .
