Plate feeding device of numerical control machine tool

Abstract

According to the plate feeding device of the numerical control machine tool, the fixing column sequentially penetrates through the third fixing inserting groove and the second fixing inserting groove so that the clamping rod and the bearing plate can be arranged in parallel, and plates to be conveyed can be stacked on the bearing plate conveniently. The two pressure sensors are used for detecting the weight of the plates to prevent the plates from being too many and exceeding the load. After to-be-conveyed plates are stacked on the bearing plate, the fixing columns are pulled out of the third fixing inserting grooves and the second fixing inserting grooves, and the clamping rods are rotated so that the clamping rods can be perpendicular to the bearing plate. And the fixing column sequentially penetrates through the third fixing inserting groove and the first fixing inserting groove so that the clamping rod can be fixed to the bearing plate. The two lead screw motors drive the to-be-conveyed plate to ascend through the bearing plate, and specifically, the two lead screw motors drive the bearing plate to ascend by the thickness of one plate every time. When the proximity sensor senses the plates, the conveying air cylinder pushes out the topmost plate through the transmission push plate, and the feeding action is achieved.

Description

Technical Field

[0001] The utility model relates to the field of plate conveying, in particular to a plate feeding device for a numerically controlled machine tool. Background Art

[0002] Wood boards are wooden panels, categorized as solid wood and composite. As the name suggests, solid wood boards are made from a single piece of wood. These boards are durable, with a natural grain, making them an excellent choice for home renovations. However, due to their high cost and demanding construction process, their use in home renovations is limited. Solid wood boards are generally categorized by the board's physical form, with no standardized specifications. Composite wood flooring, also known as laminate flooring, is often given its own names by various companies for various purposes, such as super-strong wood flooring and diamond-shaped wood flooring. Regardless of the complexity and variety of the names, these boards are all considered composite flooring. A disadvantage of composite flooring is that it can warp and deform when laid over large areas. Because it is a composite material, the edges and corners between the boards are susceptible to breaking or wear.

[0003] However, before use, wood boards need to be processed using CNC machine tools, including cutting, carving, and grinding. Conventional wood loading devices for CNC machine tools, such as the one disclosed in patent application number CN201510054291.7, entitled "Loading Device for Board Cutting Machine," suffer from low board loading efficiency, which impacts board processing efficiency. Utility Model Content

[0004] Based on this, it is necessary to provide a CNC machine tool plate loading device to address the technical problem of low efficiency in loading wood boards, which affects the processing efficiency of the boards.
