Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, and specifically discloses a box-type centering mechanism. Background Art

[0002] Conveyor belts are indispensable equipment in modern enterprise assembly lines and have a significant impact on product production efficiency. In the prior art, boxes usually need to be clamped by grabbing robots during the conveying process to facilitate the next process. However, as the box conveyor belt moves, the position of the box it is conveying changes in real time, making it impossible for the grabbing robot to position the box, resulting in partial clamping and missed clamping during the grasping process, which seriously affects the operating efficiency of the production line.

[0003] A box centering mechanism is usually provided on a box conveyor belt to correct the position of the box. The centering plates of the existing box centering mechanisms are all fixed. When centering boxes of different specifications and models, it is necessary to adjust the stroke of the cylinder, which is inconvenient. Therefore, a box-type centering mechanism is needed to solve this problem. Utility Model Content

[0004] The utility model aims to provide a box-type centering mechanism, which has the characteristic of being able to center boxes of different specifications and models without adjusting the cylinder stroke.

[0005] The cam is connected with two symmetrically distributed sliding rails on the upper end face of the base frame, and the outer walls of the two sliding rails on the same side are slidably connected with a slide plate, and the upper end faces of the two slide plates are fixedly connected with two symmetrically distributed support rods, and the outer walls of the two support rods on the same side are fixedly connected with a fixing plate, and the insides of the two fixing plates are slidably connected with four symmetrically distributed sliding rods, and the outer walls of the four sliding rods on the same side are fixedly connected with the centering plate, and the outer walls of the eight sliding rods are sleeved with springs. The center of the upper end face of the base frame is fixedly connected with a first connecting shaft, and the outer wall of the first connecting shaft is rotatably connected with a rotating plate, and the upper end face of the rotating plate is fixedly connected with two symmetrically distributed second connecting shafts, and the outer walls of the two second connecting shafts are rotatably connected with connecting rods, and the upper end faces of the two slide plates are fixedly connected with a third connecting shaft, and the other ends of the two connecting rods are rotatably connected with the two third connecting shafts.

[0006] In order to facilitate driving the slide plate to slide left and right along the slide rail, as a preferred box-type centering mechanism of the utility model, a cylinder is installed on the upper end surface of the base frame, and the output end of the cylinder is fixedly connected to one of the slide plates.

[0007] In order to prevent the sliding rod from falling off the fixing plate, as a preferred box-type centering mechanism of the utility model, the other ends of the eight sliding rods are fixedly connected to the limiting blocks.

[0008] In order to prevent the slide plate from falling off the slide rail, as a preferred box-type centering mechanism of the utility model, the longitudinal cross-section of the slide rail along the front-to-back direction is T-shaped.

[0009] In order to prevent the box body from being pinched, as a preferred box-type centering mechanism of the utility model, the outer walls opposite to each other of the two centering plates are both provided with rubber pads.

[0010] In order to facilitate the control of the equipment, as a preferred box-type centering mechanism of the utility model, a controller is provided on the front end surface of the base frame, and the cylinder is electrically connected to the controller.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] This box-type centering mechanism can drive the two centering plates to move synchronously relative to or opposite to each other through the cooperation of the cylinder, slide plate, slide rail, support rod, fixed plate, first connecting shaft, rotating plate, second connecting shaft, connecting rod and third connecting shaft, so as to center the box body. The centering plates can be extended and retracted according to the specifications of the box body through the cooperation of the slide rod, spring and limit plate. When the specifications of the box body are large, the centering plates will drive the slide rod to slide along the fixed plate to both sides when contacting with the box body. When the centering plates are separated from the box body, the slide rod and the centering plates are reset under the elastic force of the spring, so that boxes of different specifications can be centered without adjusting the stroke of the cylinder, and the use effect is good.
