[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-3 As shown, a plywood positioning and cutting device comprises a workbench 1 and a first motor 33, a cutting mechanism 2 is provided in the middle of the workbench 1, a placing bar 3 is provided on the left and right sides of the cutting mechanism 2 of the workbench 1, a bidirectional moving mechanism 31 is assembled and connected between the two placing bars 3, a vertically arranged first lead screw 32 is assembled and connected on the upper side of one end of the placing bar 3, a power output shaft of the first motor 33 is transmission-connected with the first lead screw 32, the first motor 33 is located in a groove opened at the end of the placing bar 3, the first lead screw 32 is threadedly connected with one end of a pressing plate 4, the other end of the pressing plate 4 is slidably connected with a first slide bar 5, and the first slide bar 5 is fixedly connected with the other end of the placing bar 3;

[0031] The bidirectional moving mechanism 31 includes a bidirectional screw 311, a second motor 312 and two fixed seats 313. The bidirectional screw 311 is fixedly connected between the two fixed seats 313. The output shaft of the second motor 312 is transmission-connected to the bidirectional screw 311. The two fixed seats 313 are located on the left and right sides of the cutting mechanism 2 and on the front side of the workbench 1.

[0032] According to the technical solution of this embodiment, the cross section of the placement strip 3 is square, and the bottom surface is in contact with the workbench 1, which is used to support the plywood. The bidirectional moving mechanism 31 is used to drive the placement strip 3 to move, and move inward or outward at the same time, so as to adapt to plywood of different sizes. When the size of the plywood is small, the bidirectional moving mechanism 31 moves the placement strip 3 to the side close to the cutting mechanism 2. When the size of the plywood is large, the bidirectional moving mechanism 31 moves the placement strip 3 to the side away from the cutting mechanism 2. The pressing plate 4 is used to squeeze the plywood to prevent the plywood from warping, and to position the plywood while squeezing to prevent the plywood from moving. The first lead screw 32 is used to drive the pressing plate 4 to press the plywood to prevent the plywood from warping. The plate 4 moves, and the first sliding rod 5 is used to position the pressing plate 4 to prevent the pressing plate 4 from rotating with the first screw 32 when the first screw 32 rotates; the second motor 312 drives the bidirectional screw 311 to rotate, and the fixing seat 313 is used to assemble the bidirectional screw 311; when cutting the plywood, the pressing plate 4 is first moved upward, the position of the placing strip 3 is moved to a position matching the plywood, and then the plywood is placed on the placing strip 3, and the position where the plywood needs to be cut is moved to just below the cutting mechanism 2, and then the pressing plate 4 is moved downward by controlling the first motor 33 to position the plywood, and finally the cutting mechanism 2 is controlled to cut the plywood.

[0033] Reference Figure 3 : The workbench 1 is provided with a cutting groove 11 just below the cutting mechanism 2.

[0034] In this embodiment, the cutting groove 11 is used to make way for the cutting blade of the cutting machine 22 to prevent the cutting machine 22 from cutting the workbench, while ensuring that the cutting machine can completely cut the plywood.

[0035] Reference Figure 1-2 The cutting mechanism 2 includes an inverted U-shaped frame 21, a cutting machine 22, a telescopic cylinder 23 and a slider 24. The U-shaped frame 21 is fixedly connected to the workbench 1, the slider 24 is slidably connected to the slide groove provided in the U-shaped frame 21, the slider 24 is assembled and connected with a translation mechanism 25, and the telescopic cylinder 23 is assembled and connected between the cutting machine 22 and the slider 24.

[0036] In this embodiment, the translation mechanism 25 drives the slider 25 to translate, thereby driving the cutting machine 22 to move, and the cutting machine 22 cuts the plywood.

[0037] Reference Figure 1-2 The translation mechanism 25 includes a second lead screw 251, two fixed blocks 252 and a third motor 253. The two fixed blocks 252 are fixedly connected to both sides below the U-shaped frame 21. The second lead screw 251 is assembled and connected between the two fixed blocks 252. The output shaft of the third motor 253 is transmission-connected to the second lead screw 251.

[0038] In this embodiment, the third motor 253 drives the second lead screw 251 to rotate.

[0039] Reference Figure 3 : Support blocks 6 are provided on both sides of the cutting groove 11.

[0040] In this embodiment, the support block 6 is used to support the middle part of the plywood. When the size of the plywood is large, the distance between the placement strip 3 and the middle part of the plywood is far. When the cutting machine 22 cuts the plywood, the middle part of the plywood may be deformed. The cutting machine 22 squeezes the plywood, and the support block 6 can prevent the middle part of the plywood from deforming.

[0041] Reference Figure 2-3 The left and right edges of the workbench 1 are both provided with a conveying mechanism 7, which includes a conveying roller 71 and two rotating seats 72, and the conveying roller 71 is rotatably connected between the two rotating seats 72.

[0042] In this embodiment, the conveyor roller 71 is used to convey the plywood. When the plywood is large in size and heavy in weight, the end of the plywood can be placed on the conveyor roller 71 first, and then the plywood can be pushed forward. The conveyor roller 71 rotates to move the plywood, which can effectively improve the efficiency of the staff in moving the plywood and save manpower.

[0043] Reference Figure 2 : A second slide bar 8 is slidably connected between the two placement bars 3, and positioning seats 81 are provided at both ends of the second slide bar 8. The positioning seats 81 are fixedly connected to the workbench 1, and the two positioning seats 81 are located on the rear side of the workbench 1.

[0044] In this embodiment, the second sliding rod 8 is used to prevent the placement bar 3 from being skewed, and at the same time plays a role in supporting the other end of the placement bar 3.

[0045] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
