It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0023] A trimming and punching machine for a grid printing apparatus for solar backsheets, such as Figures 1-5 As shown, the device includes a frame 1 and a trimming assembly 2, a dust removal assembly 3, a punching assembly 4, and a traction assembly 5 sequentially mounted on the frame 1. The trimming assembly 2 is used to cut off the edge of the roll material; the dust removal assembly 3 is used to remove dust from the surface of the roll material; the punching assembly 4 is used to punch holes at designated locations on the roll material; and the traction assembly 5 is used to drive the roll material to move.
[0024] In one embodiment, such as Figures 1-5As shown, the trimming assembly 2 includes a lower blade holder 21 and an upper blade holder 22. The lower blade holder 21 and the upper blade holder 22 are parallel and rotatably mounted on the frame 1. Blades 23 are mounted on the upper blade holder 22, and the roll material passes between the lower blade holder 21 and the upper blade holder 22. The distance between the blades 23 on the left and right sides of the upper blade holder 22 is the width of the back plate. The edges of the roll material can be trimmed by passing through the lower blade holder 21 and the upper blade holder 22.
[0025] In the above embodiments, such as Figures 1-5 As shown, the upper blade holder 22 includes a rotating shaft 221, a blade holder 222, a reducer 223, and a handwheel 224. The rotating shaft 221 is rotatably connected to the frame 1, and the blade holder 222 is fixed on the rotating shaft 221. The handwheel 224 is connected to the rotating shaft 221 through the reducer 223, and the handwheel 224 drives the reducer 223 to rotate the rotating shaft 221. The reducer 223 is a worm gear reducer. The handwheel drives the reducer 223 to control the rotating shaft 221 to swing and adjust the blade holder 222. The blade 23 is mounted on the blade holder 222. This structure allows the blade 23 to be engaged and disengaged. When the blade 23 is disengaged from the lower blade holder 21, it facilitates the loading of the roll material between the lower blade holder 21 and the upper blade holder 22. When the blade 23 is moved to the lower blade holder 21, it presses into the roll material, cutting the edge of the roll material. Preferably, the lower blade holder 21 is provided with a clearance groove to ensure that the blade 23 cuts the roll material in place, while avoiding damage to the lower blade holder 21.
[0026] In the above embodiments, such as Figures 1-5 As shown, the lower tool holder 21 and the upper tool post 22 are equipped with synchronous gears 24 that mesh with each other, thereby causing the lower tool holder 21 and the upper tool holder 22 to rotate synchronously.
[0027] In one embodiment, such as Figures 1-5 As shown, the traction assembly 5 includes a pressing assembly 51, a pressing roller 52, a traction roller 53, and a motor 54.

The clamping cylinder 513 drives the slider 512 to move vertically. The end of the clamping roller 52 is rotatably connected to the slider 512. The clamping cylinder 513 provides downward pressure to the slider 512, thereby pressing the clamping roller 52 against the traction roller 53 to clamp the roll material onto the traction roller 53.
[0029] In the above embodiments, such as Figures 1-5 As shown, synchronous pulleys 6 are installed on the traction roller 53, trimming assembly 2, and frame 1. The synchronous pulleys 6 are connected by a synchronous belt 7. The synchronous pulleys 6 transmit the power of the traction roller 53 to the trimming assembly 2, providing power to the trimming assembly 2. Through the cooperation of the synchronous pulleys 6 and the synchronous belt 7, the traction assembly 5 and the trimming assembly 2 move synchronously.
[0030] In one embodiment, such as Figures 1-5 As shown, the dust removal assembly 3 includes a support roller 31, a dust-adhesive roller 32, a cleaning roller 33, and a third drive assembly 34. Since the solar backsheet is printed on the upper surface of the roll material, the dust removal assembly 3 only removes dust from the upper surface. The cleaning roller 33, the dust-adhesive roller 32, and the support roller 31 are arranged in parallel at the top, middle, and bottom. The support roller 31 and the cleaning roller 33 are mounted on the frame 1. The two ends of the dust-adhesive roller 32 are mounted on the frame 1 via the third drive assembly 34. The third drive assembly 34 controls the dust-adhesive roller 32 to press against the support roller 31 or the cleaning roller 33. A film roll 35 is mounted on the cleaning roller 33; the film roll 35 cleans the surface of the dust-adhesive roller 32. When dust removal is performed on the roll material, the third drive assembly 34 controls the dust-adhesive roller 32 to press the roll material firmly onto the support roller 31; when cleaning the dust-adhesive roller 32, the third drive assembly 34 controls the dust-adhesive roller 32 to press onto the film roll 35 of the cleaning roller 33, using the film roll 35 to remove dust from the dust-adhesive roller 32. The third drive assembly 34 is a cylinder.
