[0002] In the production of wooden doors, it is necessary to saw the two surfaces of the door leaf blank to form installation grooves for installing decorative moldings on the surface of the door leaf. In the Chinese Patent Library, the Chinese patent application with publication number CN104191886B and titled "A Double-sided Engraving Machine for Wooden Door Leaf" discloses a door leaf lower surface sawing device. The device performs sawing, marking, and engraving actions on the lower surface of the door leaf through a lower tool module set on a lower crossbeam, wherein the lower tool module can move along the lower crossbeam to complete the determination of the cutting position in the width direction of the door leaf, and the lower tool module can move along the length direction of the door leaf to complete the cutting stroke of the lower tool module.

[0003] However, the lower dust collection mechanism for collecting sawing dust from the lower tool module is the same as the upper dust collection mechanism, that is, it is directly connected to the main dust removal system through a hose. Therefore, a relatively long pipeline is required to connect the movable dust collection hood and the fixed dust collection inlet, which makes the pipeline layout of the sawing device chaotic, and the long pipeline dragged back and forth is easy to affect other electrical circuits.

[0017] Preferably, the dust suction outlet is at least opened at one end of the dust suction pipe.

[0018] Preferably, the sawing device further comprises an upper sawing mechanism disposed on the crossbeam and capable of moving along the crossbeam.

[0019] Preferably, the sawing device also includes an auxiliary workbench arranged on the other side of the crossbeam, and a lifting and pressing beam installed through the workbench, and there is a gap between the workbench and the auxiliary workbench for the lower sawing mechanism to pass through, wherein at least the workbench can be transported along the y-axis direction.

Therefore, only a shorter pipeline is needed to connect the dust suction hood and the movable dust suction inlet, so that the pipeline layout of the device is tidy, avoiding the problem of chaotic pipeline layout caused by long pipelines dragging back and forth, which is easy to affect other electrical lines.

[0024] 2. In a preferred embodiment, the setting of a workbench with a gap and an auxiliary workbench can enable the door leaf to complete the feeding in the y-axis direction and reach the sawing processing position.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0033] Reference Figure 1 , Figure 2 A sawing device as shown, comprising:

[0034] Workbench 1;

[0035] The cross beam 2 is screwed and fixed on the vertical beam 5 and is located on one side of the workbench 1. The cross beam 2 extends along the x-axis direction;

[0036] A lower sawing mechanism 3, the lower sawing mechanism 3 is arranged on the crossbeam 2 and can move along the crossbeam 2;

[0037] The lower dust suction mechanism 4 includes a dust suction hood 41 and a dust suction pipe 42, wherein the dust suction hood 41 is installed on the lower sawing mechanism 4, the dust suction pipe 42 is located below the lower sawing mechanism 4 and is arranged along the x-axis direction, the dust suction pipe 42 has a movable dust suction inlet and a dust suction outlet 43 connected to the main dust removal system, and the movable dust suction inlet is connected to the dust suction hood 41 pipeline and can move with the dust suction hood 41.

[0038] By means of the above structure, the movable dust suction inlet forms a dust inlet on the dust suction pipe 42 that can move with the dust suction hood 41. When the lower sawing mechanism 4 moves and cuts along the crossbeam, the movable dust suction inlet moves synchronously with the lower sawing mechanism 4 to inhale the sawing dust generated by the lower sawing mechanism 4, and discharges the dust to the main dust removal system through the dust suction pipe 42. Therefore, the movable dust suction inlet of the dust suction pipe 42 is basically always located below the dust suction hood 41, and the distance between the movable dust suction inlet and the dust suction hood 41 is relatively small and can remain basically unchanged. Therefore, in the technical solution of the present application, only a shorter pipeline is needed to connect the dust suction hood and the movable dust suction inlet, so that the pipeline layout of the device is neat, avoiding the problem of chaotic pipeline layout caused by long pipelines dragging back and forth, or the problem of affecting other electrical circuits.

[0039] Specifically, the lower sawing mechanism 3 in this embodiment is a woodworking sawing mechanism of the prior art, which at least has a tool seat, a protective cover, a tool that can be raised and lowered, and a motor that drives the tool to rotate. The tool is arranged upward to saw, mark or carve the lower surface of the door leaf from the bottom of the door leaf. The dust cover 41 is screwed to the protective cover of the lower sawing mechanism 3 from below and communicates with the internal space of the protective cover.

[0040] Reference Figure 3 As shown, the dust suction pipe 42 is a rectangular pipe with closed ends, the movable dust suction inlet includes an open slot 44, a mask conveyor belt, and an inlet cover 45, and the dust suction outlet 43 is opened on the side of both ends of the dust suction pipe 42, and is connected to the main dust removal system through a dust cover, a hose, etc. The main dust removal system is a central dust removal system in the prior art. The open slot 44 is opened on the top surface of the dust suction pipe 42 along the x-axis direction and is connected to the internal space of the dust suction pipe.

[0041] A pair of rollers are fixedly mounted at the two ends of the dust suction pipe 42 in the manner of the prior art, for example, a pair of mounting plates are respectively screwed and mounted on the two ends of the dust suction pipe 42, mounting holes are provided on the mounting plates, the roller shafts are mounted on the pair of mounting plates through bearings, and the rollers are mounted on the roller shafts through bearings. The mask conveyor belt is a conveyor belt, which is tensioned and mounted on a pair of rollers, so that the dust suction pipe 42 is located between the upper travel section and the lower travel section of the mask conveyor belt, and the upper travel section of the mask conveyor belt covers the open groove 44. As a preferred embodiment, a pair of limiting guide rails 46 are arranged on the groove wall of the open groove 44 in the x-axis direction, and the two sides of the upper travel section of the mask conveyor belt are clamped in the pair of limiting guide rails 46, so that the upper travel section of the mask conveyor belt can always be attached to the surface of the open groove 44. In one embodiment, sealing strips can be arranged on both sides of the mask conveyor belt to cooperate with the limiting guide rails 46 to improve the sealing of the dust suction pipe 42. In another embodiment, the crawler conveyor belt can be first tensioned and installed on a pair of rollers, and the two side surfaces of the upper travel section of the crawler conveyor belt are clamped in a pair of limit rails 46, and then the mask conveyor belt is tensioned and installed on the crawler conveyor belt, and the crawler conveyor belt serves as a support for the mask conveyor belt. A connecting port is provided on the mask conveyor belt, and in this embodiment, the connecting port is a circular hole. In order to more clearly show the structure of the limit rails 46, etc., Figure 2 , Figure 3 The mask conveyor belt is not shown.

[0042] The inlet cover 45 has two opposite inlets. The first inlet is screwed and installed on the upper travel section of the mask conveyor belt, covers the connecting port and is connected to the inside of the dust suction pipe 42 through the connecting port; the second inlet has a trumpet-shaped opening, the diameter of which is the same as that of the dust suction cover 41, and is connected to the dust suction cover 41 through a hose. The inlet cover 45 is connected to the lower sawing mechanism 3 through an "L"-shaped connector 47. One end of the connector 47 is integrally formed with the inlet cover 45, and the other end is screwed and connected to the tool seat of the lower sawing mechanism 3. A head for driving the lower sawing mechanism 3 to move along the crossbeam 2 is installed on the crossbeam 2. When driving the lower sawing mechanism 3 to move, the head carries the inlet cover 45 along the crossbeam 2 with the lower sawing mechanism 3, so that the dust suction inlet formed by the inlet cover 45 can move with the movement of the lower sawing mechanism 3 and is always located below the lower sawing mechanism 3. Of course, in some other embodiments, the connector 47 can also be installed on the crossbeam 2 by sliding a slider, and the sliding drive is realized by an independent head.

[0045] By means of the above structure, there is a gap between the workbench 1 and the auxiliary workbench. After the door leaf completes the feeding in the y-axis direction and reaches the sawing processing position, the upper sawing mechanism 6 and the lower sawing mechanism 3 can directly saw the door leaf. The upper sawing mechanism 6 and the lower sawing mechanism 3 do not need to move in the y-axis direction, so the structure of the sawing device of the technical solution of the present application is relatively simple, and the sawing energy consumption is relatively low.

The lifting and lowering pressure beam 9 includes a pressure beam, and the two ends of the pressure beam are respectively screwed and arranged on the frame of the workbench 1 through a lifting gas rod. The door leaf is transported by the workbench 1 and moves to the side of the door leaf to contact the receiving support 82 and is supported by the receiving support 82 to slide to the set position. The lifting and pressing beam 9 descends to the surface of the door leaf to press it. Finally, the upper sawing mechanism 6 and the lower sawing mechanism 3 perform sawing and move along the crossbeam 2 to complete the sawing stroke.

[0047] As a preferred embodiment, the workbench 1 can also be transported along the x-axis direction. In this embodiment, the workbench 1 also includes a roller conveying mechanism 12 that can be transported along the x-axis direction, and the roller conveying mechanism 12 is a prior art. The three crawler conveying mechanisms 11 are screwed and installed on the base 7 through the lifting gas rods. Driven by the lifting gas rods, they can rise at the roller gap of the roller conveying mechanism 12 and be higher than the conveying working surface of the roller conveying mechanism 12. At this time, the lifting pressure beam 9 is set on the frame 13 of the stick conveyor 12.
