[0037] Working principle:

[0038] The cylinder drives the conveyor belt to automatically feed at a preset speed. The cardboard material at the frontmost end abuts against the stop bar. The telescopic rod of the material - taking cylinder retracts to drive the first rotating shaft to rotate. The material - taking rod drives the first suction cup to suck on the surface of the cardboard material at the frontmost end. Then, the telescopic rod of the material - taking cylinder extends to make the material - taking rod rotate to the horizontal position, so that the cardboard material falls onto the first support frame. During this process, the upper end of the cardboard material generates a bending deformation and is pulled to the other side of the stop bar;

[0039] The first fixed plate comes to the upper side of the material - taking rod in the horizontal position driven by the second slider and the lifting rod. The first fixed plate presses the rear panel of the cardboard material on the first support frame by using the second suction cup and the pressing plate. The telescopic rod of the first jacking cylinder extends to control the first sliding plate to rise. The bottom panel and the two side panels of the cardboard material are pushed to the vertical state by using the first jacking push plate and the second jacking push plate. At this time, the side panels are clamped by the second jacking push plate and the side baffle. Then, the telescopic rod of the first flipping cylinder extends to make the flipping panel rotate to the vertical state, clamping the front panel of the cardboard material between the third suction cup and the inner - supporting cylinder. The telescopic rods of the inner - supporting cylinders extend simultaneously to move the side stop bars to the specified positions. The telescopic rod of the first folding cylinder extends to drive the first rotating arm to rotate. The two side pages of the front panel of the cardboard material are folded by using the first folding rod and finally clamped between the first folding rod and the side stop bar. Then, the telescopic rod of the second folding cylinder extends to drive the second rotating arm to rotate, further driving the second rotating shaft to rotate and using the second folding rod to press the front panel of the cardboard material to the horizontal state. At this time, the two side pages of the front panel are pressed into the two side panels. Thus, the one - time forming is completed;

[0040] Each mechanism of the one-time forming mechanism returns to the initial position. The truss grasping mechanism uses the second suction cup to suck and convey the semi-finished product material after one-time forming to the second support frame. The first fixed plate uses the second suction cup and the pressing plate to press the rear panel of the semi-finished product material within the limit frame of the support pallet. Then, the first swing cylinder controls the upper pressing plate to rotate so that the upper pressing plate presses on the front panel of the semi-finished product material. The truss grasping mechanism controls the first fixed plate to rise and leave the semi-finished product material. Then, the telescopic rod of the folding cylinder extends to drive the third rotating arm to rotate, and the inner small page of the semi-finished product material is turned upward by using the folding L-shaped rod to make it close to the inner large page. Then, the rotating cylinder controls the rotating L-shaped rod to rotate so that the tongue telescopic cylinder comes directly above the inner small page and the inner large page. The telescopic rod of the tongue telescopic cylinder extends to clamp the inner small page and the inner large page between two tongues on the same side. Then, the rotating cylinder controls the rotating L-shaped rod to rotate and uses the tongue to fold the inner small page and the inner large page to the inside of the semi-finished product material. Then, the second swing cylinder controls the side pressing plate to rotate so that the side pressing plate presses on the outside of the inner large page. The telescopic rod of the tongue telescopic cylinder retracts. Then, the second lifting cylinder pushes the fourth fixed plate upward so that the end of the propulsion cylinder aligns with the inner cavity of the semi-finished product material. The telescopic rod of the propulsion cylinder extends to push the push plate cylinder into the inner cavity of the semi-finished product material. The telescopic rods of the two push plate cylinders extend to both sides and use the inner support pressing plate to push the inner large page so that the inner large page and the inner small page are pressed tightly on the side panel of the semi-finished product material. Thus, the secondary forming is completed, and the finished product material is obtained.

[0041] Each mechanism of the secondary forming mechanism returns to the initial position. The telescopic rod of the second flipping cylinder extends to rotate the support pallet 90° to the vertical position. Then, the telescopic rod of the pushing cylinder extends through the pushing outlet to push out the finished product material, which falls onto the conveyor belt behind the secondary forming mechanism.

[0042] At the upper end of the frame 101, a first slide rail 112 is provided beside the cylinder-driven conveyor belt 102. The first slide rail 112 is parallel to the cylinder-driven conveyor belt 102. A first slider 113 is slidably connected to the first slide rail 112. The upper end of the first slider 113 is connected to a push plate 114. A torque reel 115 is provided on the frame 101. The torque reel 115 is located on the discharge side of the cylinder-driven conveyor belt 102. The cable of the torque reel 115 is connected to the first slider 113. The torque reel can continuously apply a pulling force to the first slider, so that the push plate can always press on the outermost material to prevent the material from tipping over.
