Description

Technical Field

[0001] The utility model relates to the technical field of box gluing machines, in particular to a feeding mechanism for a box gluing machine. Background Technique

[0002] A box gluing machine is a kind of carton processing equipment for gluing packaging boxes. It folds and glues the cut cardboard into shape. The box gluing machine is divided into a paper feeding part, a pre-folding part, a bottom hooking part, a forming part, and a box pressing part. The box pressing part of an ordinary box gluing machine is composed of a long bracket or a vertical bracket and a widened transmission belt. The glued packaging box is clamped between the upper and lower conveyor belts to obtain a certain pressure, forming a firm bonding layer. A feeding mechanism is usually assembled at one end of the transmission belt of the box gluing machine for feeding the cardboard of the carton.

[0003] The existing feeding mechanism of the box gluing machine usually limits and fixes the two sides of the cardboard of the carton through two groups of limit plates. When adjusting the limit plates, it is necessary to rotate multiple groups of threaded rods for adjustment, which is rather cumbersome. Moreover, the two groups of limit plates need to be adjusted separately, and manual adjustment is likely to cause the cardboard of the carton to be not centered, thus affecting the subsequent processing effect of the cardboard of the carton.

[0031] Example 3

[0032] Please refer to Figures 1-4 , on the basis of the above embodiments, the limit structure 4 of this embodiment is provided at one end of the conveyor belt 1. The limit structure 4 includes a limit frame 401 bolted to one side of the side plate of the conveyor belt 1. The limit frame 401 is a hollow cuboid shape, and both ends of the limit frame 401 are connected to the side plate of the conveyor belt 1 by bolts. A limit block 402 is arranged inside the limit frame 401. The upper part of the limit block 402 is a curved surface shape, and an anti-slip pad is arranged at the position of the curved surface shape to ensure the fixing effect of the limit block 402 on the rotating rod 308. A connecting rod 403 welded to the bottom of the limit block 402 to prevent the connecting rod 403 from separating from the limit block 402. A spring 404 is arranged inside the limit frame 401. The spring 404 is in a semi-compressed state. A pull plate 405 welded to one end of the connecting rod 403. By pulling the pull plate 405, the connecting rod 403 can be driven to move. And an anti-slip rubber is arranged on the outside of the pull plate 405 to prevent the staff from slipping. The limit block 402 is slidably connected to the limit frame 401, and both sides of the limit block 402 are in contact with the inner wall of the limit frame 401 to ensure the stability of the limit block 402 during movement. The top of the spring 404 is in contact with the bottom of the limit block 402, and the bottom of the spring 404 is in contact with the inner wall of the limit frame 401. Through the spring 404, the limit block 402 can quickly return to the initial position to fix the rotating rod 308. The connecting rod 403 is a cylinder, and the connecting rod 403 passes through the hole formed in the center of the spring 404. Through the connecting rod 403, the spring 404 can be limited to prevent the spring 404 from deforming and misaligning. A fixed block 406 is slidably connected to the bottom of the limit frame 401, and the fixed block 406 is in contact with the pull plate 405. Through the fixed block 406, the pull plate 405 can be fixed to prevent the limit block 402 from affecting the rotating rod 308.

[0033] Working principle: First, when it is necessary to load the cardboard boxes, place the stacked cardboard boxes above the conveyor belt 1 and between the two rotating rollers 304. Then pull the fixed block 406 to separate it from the pull plate 405. Then pull the pull plate 405 downward. The movement of the pull plate 405 will drive the connecting rod 403 to move. The movement of the connecting rod 403 will drive the limit block 402 to move downward. The limit block 402 moves away from the rotating rod 308, and the movement of the limit block 402 will cause the spring 404 to deform. When the pull plate 405 is below the fixed block 406, slide the fixed block 406 again to make it fit with the upper part of the pull plate 405. The pull plate 405 is fixed to a certain extent by the fixed block 406 to prevent the spring 404 from rebounding;

[0034] Secondly, rotate the rotating rod 308. The rotation of the rotating rod 308 will drive the second transmission wheel 307 to rotate. Since the second transmission wheel 307 is meshed with the transmission belt 306, and the first transmission wheel 305 is also meshed with the transmission belt 306, the rotation of the second transmission wheel 307 will drive the first transmission wheel 305 to rotate. The rotation of the first transmission wheel 305 will drive the threaded rod 302 to rotate. Since the threaded rod 302 is threadedly connected to the mounting frame 303, and the mounting frame 303 is height-connected to the sliding rod 309, the rotation of the threaded rod 302 will drive the mounting frame 303 to move horizontally above the conveyor belt 1 under the influence of the thread. The movement of the mounting frame 303 will drive the rotating roller 304 to move, and the rotating roller 304 will move to fit both sides of the cardboard box, thus preventing the cardboard box from shaking during transportation.

[0035] Finally, when the adjustment of the rotating roller 304 is completed, slide the fixed block 406 again to separate it from the pull plate 405. At this time, the compressed spring 404 will restore its deformation and push the limiting block 402 to move downward. The limiting block 402 will move to fit the outer wall of the rotating rod 308, and the rotating rod 308 is limited and fixed by the limiting block 402 to prevent the rotating rod 308 from shaking under the influence of the outside world.

[0036] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
