Description

Technical Field

[0001] The utility model relates to the field of plywood production, in particular to a cutting and clamping mechanism for plywood. Background Art

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesives. It is usually made of an odd number of veneers, and the fibers of adjacent veneers are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major wood-based panels. It can also be used as a material for airplanes, ships, trains, cars, buildings, and packaging boxes. Plywood has excellent performance and a large market demand. During the process of plywood processing and shearing, a clamping device is required to clamp and fix the plywood, and then the plywood is transferred to the shear blade for cutting.

[0003] According to the disclosed patent 202320889653.4, a cutting and clamping mechanism for plywood includes a mounting plate, a storage plate is slidably installed in the middle of the upper end of the mounting plate, a support column is fixedly installed on the left side of the top end of the storage plate, a cross bar is arranged on the right side of the top end of the support column, a mounting block is slidably installed in the middle of the inner side of the cross bar, a cylinder is fixedly installed in the middle of the bottom end of the mounting block, a push plate is fixedly installed on the output end of the cylinder, a pressing plate is slidably installed in the middle of the bottom end of the push plate, the pressing plate is located in the middle of the upper part of the storage plate, and multiple groups of elastic components are arranged between the pressing plate and the push plate, the elastic component includes a fixed rod, the fixed rod is fixedly installed in the middle of the bottom end of the push plate, a spring is arranged in the middle of the inner side of the fixed rod, and a movable rod is fixedly installed at the bottom end of the spring. The utility model can reduce the impact force generated by the pressing plate when pressing by the elastic component, so as to avoid the situation that the surface of the plywood is scratched and damaged due to the force when the plywood is clamped. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: although the push plate is pushed by the output end of the cylinder, so that the push plate drives the pressing plate to slide downward, when the pressing plate and the storage plate are closed and connected, the plywood placed on the surface of the storage plate is clamped and fixed, which solves the problem that the thickness of the plywood is relatively thin , which makes the force-bearing surface of the clamping block and the plywood small. At the same time, most clamping mechanisms lack a buffer protection structure, which leads to the problem of extrusion and damage to both ends of the plywood when the plywood is clamped and fixed. However, during use, the traditional plywood cutting and clamping mechanism performs a single-point extrusion limit on the plywood from the top. The stability of the single-point extrusion limit is not very high, which makes the plywood easy to move, affecting the cutting of the plywood. Moreover, the number of clamps at one time is small, which requires the staff to repeatedly disassemble and assemble the plywood, reducing the efficiency of plywood cutting. For this reason, a new technical solution needs to be designed to solve it. Utility Model Content
