Description

Technical Field

[0001] This utility model relates to the technical field of board positioning and correction devices, and in particular to a board positioning and correction device for plywood conveying. Background Technology

[0002] In the production, processing, and subsequent assembly of plywood, the positioning accuracy of the conveying system directly affects the processing quality of subsequent processes such as cutting, edge banding, and drilling. It is a crucial link in ensuring product dimensional consistency and assembly accuracy. Currently, plywood conveying mainly relies on belt conveyors for continuous transmission. To avoid positional deviations of the boards during conveying due to uneven force, conveyor belt misalignment, or initial placement offset, positioning mechanisms are typically installed on both sides of the conveyor belt to center and correct the boards.

[0003] In existing technologies, positioning and correction devices for plywood conveying mostly employ a fixed-installation centering plate structure. The centering plate is connected to the conveyor frame via a bracket, and the two centering plates on both sides form a conveying channel adapted to the width of the plywood, achieving passive centering of the plywood. However, existing centering plates are mostly rigid fixed structures, lacking height adjustment capabilities and making it difficult to dynamically adapt to the actual thickness of the plywood and the conveying conditions. During the conveying process, some plywood may experience localized stress concentration when in contact with the centering plate due to uneven edges, warping, or other issues, leading to secondary displacement of the plywood and affecting the accuracy control of subsequent processing steps.

[0012] (III) Beneficial Effects This utility model provides a plywood positioning and correction device for plywood conveying, which has the following beneficial effects: 1. This plywood conveying board positioning and correction device, through the setting of the centering mechanism, when in use, connect the power supply and start the electric push rods on both sides of the support platform. The electric push rods extend and retract, driving the end centering plate to move relative to each other, and perform centering and correction processing on the board that has moved to the middle. The position of the positioning cylinder on the adjusting rod can be adjusted according to the thickness of the board and fixed with positioning screws. This achieves the effect of adjusting the height of the centering plate installed on one side of the positioning cylinder, avoiding the inability to dynamically adapt to the actual thickness of the board and the conveying state due to the lack of height adjustment capability, thus affecting the centering effect of the board.

[0013] 2. This plywood conveying board positioning and correction device, through the setting of an auxiliary buffer mechanism, has connecting frames on the inner walls of both sides of the support platform when the board is conveyed to the centering structure. Several rotatable auxiliary rollers installed on the connecting frames can assist the movement of the offset board. When the board deviates on the conveyor belt and contacts one of the auxiliary rollers, the auxiliary rollers change the sliding friction between the board and the equipment into rolling friction through their own rotation, thereby effectively reducing resistance and realizing automatic and flexible correction of the board's running trajectory, avoiding edge damage to the board and equipment jamming caused by forced extrusion.

[0018] In this invention, the working steps of the device are as follows: First step: When using, connect the power supply and start the electric push rods 306 on both sides of the support platform 1. The electric push rods 306 extend and retract and drive the centering plate 307 at the end to move relative to each other, so as to center and correct the plate that has moved to the middle.

Several rotatable auxiliary rollers 402 installed on the connecting frame 401 can assist the plate to move if it deviates. When the plate deviates on the conveyor belt and comes into contact with the auxiliary roller 402 on one side, the auxiliary roller 402 will change the sliding friction between the plate and the equipment into rolling friction through its own rotation, thereby effectively reducing resistance and realizing automatic and flexible correction of the plate's running trajectory.
