Description

technical field [0001] The invention belongs to the technical field of wood processing machinery, and in particular relates to a multifunctional automatic jigsaw machine. 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 a board for furniture, cabinets and interior decoration, its positive significance lies in saving 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 base) in a suspended ...

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 action cylinder, and the frequent friction between the push plate and the push plate platform of the frame will damage the push plate; third, because only the upper surface of the plate can be heated, the lower surface of the plate The heating effect is poor, which affects the overall bonding effect of adjacent sheets after splicing

In addition, this CN2265880Y also has the following shortcomings: First, due to the lack of a rationally structured lateral jacking mechanism, there is a risk of gaps between the ends of adjacent slats (called blanks in the patent), which will eventually affect the entire width. The splicing effect of the width direction of the board; second, because the up and down floating connection (patent called suspension) of multiple heating tubes is only carried out by a support rod at each end of each heating tube, so the slats passing under the heating tube The overall compression effect cannot reach a satisfactory level; thirdly, because the patent realizes the adjustment of the height of the lower heating tube (the patent is called a thermal workbench) through the power transmission mechanism arranged at the bottom of the frame, specifically The lead screw is driven by the motor through the reducer, and then the guide rail slide is driven by the lead screw, and then the roller mechanism fixed on the lower heating tube is driven by the guide rail slide, and finally the lower heating tube (that is, the thermal workbench described in the patent) is lowered or raised. , so as to adapt to the thickness change of the slats to be spliced, but the structure of the power transmission mechanism (the industry customarily called the lifting mechanism) is relatively complicated

[0004] Another example is that the authorized announcement number CN2425206Y provides a "pushing board type jigsaw machine". This patent scheme focuses on the specific structure of the pushing mechanism. and crankshaft, so the structure is more complex and bulky
