Description

technical field [0001] The invention belongs to the technical field of wood processing machinery, and in particular relates to an automatic jigsaw machine with a beam adjustment function. Background technique [0002] The function of the jigsaw machine mentioned above is to splice the slats of different lengths but tend to be the same in thickness and width produced by wood product manufacturers in the process of producing wood products into such as 122 (width) × 244 (length) ) cm whole board, used as furniture, cabinets and interior decoration boards, its positive significance lies in the saving of precious wood resources. [0003] The technical information about the jigsaw machine can be seen in the published Chinese patent literature, such as the authorized announcement number CN2265880Y recommending a "heating jigsaw machine". Both ends of the heating tube are provided with support rods, and the heating tube is placed on the upper part of the frame (patent called the ba...

Problems solved by technology

Although this patent solution can realize the technical effect of the penultimate 6th line to the penultimate line 3rd line on the first page of the instruction manual, since the pushing mechanism only consists of a pair of pushing plate action cylinders (patent optional oil cylinders) and a The pusher plate of the plate action cylinder is composed of a pusher plate connected to the end of the cylinder column, so in the actual use process, the pusher mechanism will inevitably produce the following technical problems: First, because the pusher plate is relatively lengthy (usually larger than equal to 122㎝), and because the middle part of the length direction of the pusher plate facing the side of the pusher plate action cylinder is connected to the end of the pusher plate action cylinder column, the cylinder column protrudes out of the cylinder when the push plate action When driving the pusher plate to move, the pusher plate behaves as a negative movement, that is, a passive movement. It is difficult to guarantee the overall movement effect of the pusher plate, that is to say, it is difficult to ensure the overall synchronous movement of the two ends and the middle of the entire pusher plate. effect, which affects the balanced pushing effect of the sheet material entering the sheet material cavity on the frame; secondly, because the pusher plate is directly placed on the pusher plate platform of the frame, the frictional resistance is large, which is not conducive to saving push. The energy consumption of the plate acting on the cylinder, and the frequent friction between the pushing plate and the pushing plate platform of the frame will damage the pushing plate; third, because only one heating mechanism heats the upper part of the plate, it is not conducive to ensuring The overall bonding effect between the adjacent panels of the panel splicing, because heating the panel on one side will cause the panel to be heated to produce a yin and yang situation. Specifically, the side facing the heating mechanism can obtain the desired heating effect, while the side away from The plate on one side of the heating mechanism is not heated enough; Fourth, because it realizes the overall lifting of the workbench through the roller mechanisms arranged at both ends of the workbench, that is, the overall lift of the workbench responds to changes in the thickness of the plate, and drives The lifting device of the roller mechanism is composed of a motor, a reducer, a screw, a push plate and a guide rail slide plate, etc., so the overall structure is relatively complicated

In addition, because this patent can only heat the upper part of the slats, the splicing effect will be inferior to that of the aforementioned CN2265880Y, and there are also some defects described in CN2265880Y
