A third transmission roller 413 is mounted on the inner wall of the fifth driven gear 412.

[0028] The limiting component 5 includes a cylinder 501 mounted on the top surface of the housing 3, a slider 502 mounted on the bottom surface of the cylinder 501, and a limiting roller 503 rotatably connected to one side surface of the slider 502.

[0029] The cutting assembly 6 includes a mounting base 601 mounted on one side surface of the housing 3. A second motor 602 is mounted on the top surface of the mounting base 601. A drive rod 603 is mounted on the output end of the second motor 602. A mounting block 604 is mounted on the outer wall of the drive rod 603. A saw blade 605 is mounted on the outer wall of the mounting block 604. A fixing screw 606 is mounted on the inner wall of the mounting block 604.

[0030] The protective assembly 7 includes a protective shell 701 installed on the top surface of the housing 3, a protective cover 702 installed on one side surface of the protective shell 701, a third motor 703 installed on the top surface of the protective shell 701, a worm gear 704 installed at the output end of the third motor 703, a worm wheel 705 installed on the outer wall of the worm gear 704, a top cover 706 installed on the inner wall of the worm wheel 705, and a dust suction port 707 installed on one side surface of the top cover 706.

[0031] In this embodiment, as Figure 2 As shown, the first motor 401, through the drive gear 402 and the first chain 403, forms a transmission mechanism with the first driven gear 404. This design allows the first motor 401 to be started, driving the first driven gear 404 to rotate via the drive gear 402 and the first chain 403, causing the first transmission roller 405 to rotate. The first transmission roller 405 then drives the second transmission roller 409 to rotate via the second driven gear 406, the second chain 407, and the third driven gear 408. The second transmission roller 409 then drives the third transmission roller 413 to rotate via the fourth driven gear 410, the third chain 411, and the fifth driven gear 412. This synchronous rotation of the first transmission roller 405, the second transmission roller 409, and the third transmission roller 413 enables efficient conveying of plywood.

[0032] In this embodiment, as Figure 3 As shown, cylinder 501 and slider 502 constitute a telescopic mechanism. With this design, the slider 502 can be extended by cylinder 501 according to the thickness of the plywood. The inner wall of housing 3 is provided with a slide rail, and the slider 502 slides on the outer wall of the slide rail, thereby adjusting the height of the limiting roller 503. The limiting roller 503, together with the first transmission roller 405, the second transmission roller 409 and the third transmission roller 413, effectively limits the upper and lower sides of the plywood, preventing the plywood from shifting during conveying and cutting, thus affecting the cutting quality of the plywood.

[0033] In this embodiment, as Figure 4 As shown, the second motor 602 forms a transmission mechanism with the saw blade 605 through the drive rod 603 and the mounting block 604. With this design, the second motor 602 can be started, and the second motor 602 drives the saw blade 605 to rotate through the drive rod 603 and the mounting block 604, which can realize the cutting function of plywood.

[0034] In this embodiment, as Figure 4As shown, the inner wall of the drive rod 603 has several threaded holes with the same size and structure. This design makes it easy to align the saw blade 605 with the threaded holes via the mounting block 604 and then fix it with the fixing screw 606. The spacing of the saw blade 605 can be adjusted according to the cutting spacing requirements, and the number of saw blades 605 can be increased or decreased, which is convenient for cutting plywood.

[0035] In this embodiment, as Figure 5 As shown, the third motor 703 forms a transmission mechanism with the top cover 706 through the worm gear 704 and worm wheel 705. With this design, the third motor 703 can be started, and the third motor 703 drives the worm gear 704 to rotate. Through the meshing of the worm gear 704 and the worm wheel 705, the worm wheel 705 is driven to rotate, thereby realizing the opening and closing function of the top cover 706. The top cover 706 can protect the user from flying debris and prevent it from endangering the user's safety. The top cover 706 can also be opened to facilitate maintenance of the internal parts of the equipment.

[0036] In this embodiment, as Figure 1 As shown, the vacuum pump 9 forms a dust collection mechanism through the air pipe 8 and the dust suction port 707. With this design, when the saw blade 605 cuts the plywood, dust will be stirred up. The vacuum pump 9 can be activated, and the vacuum pump 9 can effectively absorb the dust and fine debris through the air pipe 8 and the dust suction port 707, so as to avoid the dust from harming the user's health.

[0037] The method of use and advantages of this utility model: The working process of this plywood strip cutting device is as follows:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the spacing of the saw blades 605 can be adjusted according to the required cutting spacing, and the number of saw blades 605 can be increased or decreased to facilitate the cutting of plywood. Then, according to the thickness of the plywood, the slider 502 is extended by the cylinder 501. The inner wall of the housing 3 is provided with a slide rail, and the slider 502 slides on the outer wall of the slide rail. The height of the limiting roller 503 is adjusted by the cylinder 501, so that the upper and lower sides of the plywood are effectively limited by the limiting roller 503, the first transmission roller 405, the second transmission roller 409 and the third transmission roller 413. The plywood is fed into the housing 3 through the feeding table 11. The first motor 401 is started. The first motor 401 drives the first driven gear 404 to rotate through the drive gear 402 and the first chain 403, so that the first transmission roller 405 rotates. The first drive roller 405 drives the second drive roller 409 to rotate via the second driven gear 406, the second chain 407, and the third driven gear 408. The second drive roller 409 drives the third drive roller 413 to rotate via the fourth driven gear 410, the third chain 411, and the fifth driven gear 412. This allows for the synchronous rotation of the first drive roller 405, the second drive roller 409, and the third drive roller 413, effectively conveying the plywood. The second motor 602 drives the saw blade 605 to rotate via the drive rod 603 and the mounting block 604, cutting the plywood. At the same time, the vacuum pump 9 is activated. The vacuum pump 9 absorbs dust and fine debris through the air pipe 8 and the dust suction port 707. The cut plywood is then conveyed to the surface of the discharge table 12, where it can be manually discharged.
