[0002] Cartons are the most widely used packaging products and can be divided into corrugated boxes, single-layer cardboard boxes, etc. They have many different specifications and models. During the carton production process, the cartons need to undergo a series of processing before they can be put into practical use. Among them, folding is also a necessary link in carton production.

[0003] A folding device for carton production disclosed in Chinese patent publication CN210940647U neatly places the finished cardboard in a placement slot, and a spring on one side of the handle can squeeze the finished cardboard toward the outlet, so that the finished cardboard can enter the conveyor belt through the paper outlet at the lower end of the placement slot.

[0004] In actual applications, it is found that when the finished cardboard falls from the placement slot through the paper outlet to the conveyor belt, the finished cardboard may deflect relative to the conveyor belt, and then the finished cardboard cannot be aligned with the limit plate and the folding plate. The deflected cardboard is difficult to meet the folding standard. For this reason, we provide a folding device for carton production. Utility Model Content

[0030] Please refer to Figure 1and Figure 2 A folding mechanism 3 for folding the cardboard 5 is provided on the mounting shell 1. The folding mechanism 3 includes a U-shaped mounting plate 301 fixed on the top surface of the mounting shell 1. A first electric push rod 302 with an output end facing downward is fixed on the top of the U-shaped mounting plate 301. The model of the first electric push rod 302 is LX800. A pressing plate 303 is fixed on the output end of the first electric push rod 302. Four baffles 304 are fixed on the mounting shell 1. Specifically, when the cardboard 5 moves onto the four baffles 304, the start of the first electric push rod 302 can drive the pressing plate 303 to approach the direction of the cardboard 5, and then the cardboard 5 on the conveyor belt 204 is squeezed by the pressing plate 303. The folding of the cardboard 5 is completed by the coordinated arrangement of the four baffles 304 and the pressing plate 303. After the folding is completed, the pressing plate 303 is driven by the first electric push rod 302 to move upward, and the folded cardboard 5 can be taken out.

[0031] The top surfaces of the four baffles 304 are all fixed with guide plates 305, and the curved ends of the four guide plates 305 are away from each other. The guide plates 305 can effectively prevent the top of the baffles 304 from damaging the cardboard 5, and prevent the edges and corners of the top of the baffles 304 from directly contacting the cardboard 5.

[0033] A push rod 405 that penetrates the storage box 401 is fixed to one side of the push plate 404 away from the outlet 403, and a connecting plate 406 is fixed to the other end of the push rod 405. A second electric push rod 407 whose output end and the connecting plate 406 are fixed to the side of the storage box 401 is fixed. The model of the second electric push rod 407 is LX800. The inner bottom wall of the storage box 401 is rotatably connected with evenly distributed rotating rods 408. The setting of the rotating rods 408 can reduce the friction between the cardboard 5 and the inner bottom wall of the storage box 401. Two symmetrical guide blocks 409 are fixed to the top surface of the mounting shell 1. The two guide blocks 409 are fixed to the storage box 401. The setting of the guide blocks 409 can guide the cardboard 5 that comes out of the outlet 403, and further avoid the deflection of the cardboard 5.

[0034] Specifically, the area between the storage box 401 and the fixed plate 402 can store the cardboard 5. The activation of the second electric push rod 407 will drive the connecting plate 406 and the push rod 405 to push the push plate 404, and then the cardboard 5 on the bottom wall of the storage box 401 will be pushed by the push plate 404. The cardboard 5 will be pushed onto the conveyor belt 204 through the outlet 403, and the cardboard 5 will be driven to the top of the four baffles 304 by the conveyor belt 204, and the cardboard 5 will be pushed out by the push plate 404, thereby avoiding the cardboard 5 from deflecting relative to the conveyor belt 204 during the loading process.

[0035] Please refer to Figure 5 Specifically, the area formed between the inner wall of the storage box 401 and the fixed plate 402 stores the cardboard 5, and the length of the outlet 403 in the vertical direction is greater than the thickness of the cardboard 5, and the length of the outlet 403 in the vertical direction is less than the thickness of two cardboards 5, so as to avoid the length of the outlet 403 in the vertical direction being too small, resulting in the cardboard 5 not being smoothly pushed out from the outlet 403 by the push plate 404, and the length of the push plate 404 in the vertical direction is less than the thickness of the cardboard 5, so the push plate 404 can only push one cardboard 5 at a time, so as to avoid the push plate 404 pushing out multiple cardboards 5 at a time and avoiding the cardboards 5 from stacking.

[0036] Working principle: first, place the cardboard 5 between the storage box 401 and the fixed plate 402, then start the motor 201 and the second electric push rod 407. The start of the motor 201 can drive the active roller 202, the driven roller 203 and the conveyor belt 204 to rotate. The start of the second electric push rod 407 can drive the connecting plate 406 and the push rod 405 to push the push plate 404, and then push the cardboard 5 on the bottom wall of the storage box 401 through the push plate 404. The cardboard 5 will be pushed onto the conveyor belt 204 through the outlet 403, so as to realize automatic loading of the cardboard 5. When the cardboard 5 moves to the top of the four baffles 304, the start of the first electric push rod 302 can drive the pressing plate 303 to rise and fall, and the pressing plate 303 squeezes the cardboard 5 on the conveyor belt 204, and the folding of the cardboard 5 is completed through the cooperation of the four baffles 304 and the pressing plate 303.
