Description

Jigsaw

technical field

The invention relates to the technical field of woodworking machinery manufacturing, in particular to a plate pushing device for a jigsaw machine.

Background technique

At present, wooden splicing panels with a variety of thicknesses and a length x width of 2440mm x 1220mm are one of the most widely used panels in the furniture and home improvement industry. The splicing panels of this specification are spliced by small-width slats through a splicing machine; The feeding device, the frame is sequentially provided with a flattening and pressure-holding device, a pressure-holding device, and a board-cutting and board-out device on one side of the feeding device. There are the following problems in the use of this kind of jigsaw machine: 1. Since the feeding device is arranged at the front end of the jigsaw table, the slats are continuously fed by pushing one slat type at a time through the pusher plate, and pass through the last slat The glue coated on the side is bonded to the side of the previous slat; due to continuous feeding, the glue between adjacent slats overflows outwards under repeated lateral extrusion; It is very long, and usually a slat needs to be laterally squeezed hundreds of times from the board into the board to the board out of the board, which will cause gaps and cracks due to insufficient glue filling between the boards during the pressurization and pressure holding stage of the spliced boards. The phenomenon of weak bonding; 2. Since the slats are continuously fed, the continuous feeding of one slat is pushed through the pusher plate at a time, and the glue coated on the side of the latter slat is combined with the previous slat. The side bonding of the slats is also sent to the leveling device by the slats at the rear for splicing and fixing. The leveling device can only correct and flatten a single slat or the joint of two slats It is impossible to correct and flatten the entire splicing panel, and there are thickness errors and warping errors in the slats. Therefore, the surface of the splicing panel is prone to warping deformation and uneven surface.
