Description

technical field [0001] The invention relates to a pre-feeding positioning method and a device for a molded plate, belonging to the technical field of pre-cutting positioning of plates. Background technique [0002] The multi-blade saw is mainly composed of a frame, a transmission mechanism, a cutter shaft, multiple sets of circular saw blades installed on the cutter shaft, and a feeding mechanism. The composite floor or solid wood floor and other boards are placed on the feeding mechanism, and the positioning is carried out by the feeding mechanism. The sheet is sent to the saw blade at a constant speed for cutting into required sheet-shaped finished products, which can greatly improve production efficiency. The conventional plate feeding device is mainly composed of a positioning mechanism, a pressing mechanism and a pushing mechanism installed on the bracket. The positioning mechanism determines whether the plate is in place. The material is pushed into the slicing mechan...

AI Technical Summary

Problems solved by technology

Manually place the sheet on the conveying table, manually position the sheet and push it into the multi-blade saw for cutting, not only the production efficiency is low, but also the finished product is low

2. Use semi-automatic positioning and cutting. If you use a positioning ruler to position the sheet and enter it into a multi-blade saw for cutting, these positioning methods must be manually involved in the positioning, and it is impossible to complete the fully automatic cutting production of the molded floor.

It has the advantages of high production efficiency and improved yield of cutting sheets. The positioning device uses more than two groove positioning rods to locate the groove in the middle of the sheet, because the groove positioning rod is positioned along the longitudinal direction of the sheet. , can effectively control the longitudinal offset phenomenon of the sheet metal, and also reduce the cumulative error caused by the manufacturing error of the sheet metal, but the bottom of the groove bar positioning rod is hemispherical or arc surface or V-shaped, during the downward movement of the sliding seat The position of the sheet is adjusted by contacting the bottom surface of the trough positioning rod with the sheet material, but since the trough positioning rod only moves downward, and the depth of the V-shaped groove of the sheet material is limited, the groove positioning rod is not easy to move. Large and heavy sheets reduce the reliability of automatic positioning

[0003] Furthermore, one kind of pressing mechanism is through pressing from top to bottom. It is to install a plurality of pressing cylinders on the frame, and press the material plate on the worktable through a plurality of pressing cylinders. Due to structural limitations, it will cause The deformation of the workbench where the sheet is placed affects the yield of the sheet

Another structure adopts the suction cup clamping structure, which can fix the sheet on the suction cup under the action of negative pressure gas, especially for some slightly warped sheets, the sheet can be flattened by negative pressure gas, so it can improve the cutting efficiency. The finished product rate of the slicing board is high, but there is also the problem of high cleanliness of the suction cup. Although the dust can be sucked into the air duct by the suction fan when cutting the material board, it will still affect the working environment and it is difficult to maintain the suction cup. Cleanliness due to reduced clamping force on the sheet

However, the driving mechanisms of the above two structures use the driving mechanism to push the workbench. On the one hand, the driving structure is complex and inconvenient to debug. On the other hand, because it drives the mobile workbench, the energy consumption is high.
