Automatic board jointer with turning plate having traction function

Abstract

The invention discloses an automatic board jointer with a turning plate having a traction function, and belongs to the technical field of woodworking machinery. The automatic board jointer comprises a rack, an upper heating mechanism, a lower heating mechanism, a board pressing mechanism, a turning mechanism and a pushing mechanism, and is characterized in that the pushing mechanism comprises a pair of pushing plate acting cylinders, a pushing plate and a pair of pushing plate synchronization devices, wherein the upper heating mechanism comprises a group of upper heating tubes and an upper heating tube heating medium lead-in and lead-out header pipe; the lower heating mechanism comprises a group of lower heating tubes and a lower heating tube heating medium lead-in and lead-out header pipe; a group of upper and lower heating tubes form a board line shifting passage; the board pressing mechanism is fixedly arranged on the upper heating tubes; the turning mechanism comprises a turning acting cylinder, a turning arm, a turning plate shaft and a turning plate. The pushing plate can achieve a good integral movement effect; the movement resistance of the pushing plate is obviously reduced; the turning plate can be reliably kept in a control state of the plate after turning, collapse of plates in a laminated state is avoided, and normal work of the board pressing mechanism and the pushing mechanism is guaranteed.

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 turning board having a traction function. Background technique [0002] The function of the jigsaw machine mentioned above is to splice the slats of different lengths but with the same thickness and width produced by the wood product processing enterprises 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 (...

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 action cylinder of the material plate, and the frequent friction between the material pushing plate and the pushing plate platform of the frame will damage the material pushing plate; third, when the material turning plate (patent called turning plate workbench) is turned 90° When the boards laid on it in a flat state form a top-to-bottom stacked state, that is, when the boards are in the state of being controlled by the turning board, due to the lack of a traction device to keep the turning board in a vertical state , so when the sheet pressure mechanism exerts pressure on the sheet controlled by the turning board, the turning board will turn away from the direction of the sheet (that is, return), causing the sheets that were originally in the stacked state to lose It collapsed due to the control, which will eventually affect the normal work of the sheet metal pressing mechanism and the pushing mechanism
