[0032] See also Figure 5-Figure 8 The positioning assembly includes: a transmission gear 6, a moving block 7, an adjusting block 8 and a positioning block 802; the transmission gear 6 is arranged inside the positioning box 5, the moving block 7 is arranged inside the positioning box 5, an adjusting slot 702 is provided at the bottom of the moving block 7, the adjusting block 8 is provided inside the adjusting slot 702, the positioning block 802 is provided at the bottom of the adjusting block 8, a slot 502 is provided at the top of the positioning box 5, a slide slot 501 is provided inside the positioning box 5, a transmission slot 504 is provided on one side of the positioning box 5, and one side of the transmission gear 6 protrudes from the positioning box through the transmission slot 504. The outer surface of the positioning box 5 and the bottom of the positioning box 5 are provided with a moving groove 503, a transmission plate 704 is connected to one side of the moving block 7, and the transmission plate 704 is provided with teeth meshing with the transmission gear 6, and the transmission plate 704 corresponds to the position of the slot 502, and a gear plate 4011 meshing with the transmission gear 6 is connected to one side of the lifting plate 401, an inclined surface is provided at the bottom end of the positioning block 802, and a compression groove 803 is provided at the top of the positioning block 802, and a compression spring 804 is connected inside the compression groove 803, and the top of the compression spring 804 is connected to the bottom of the adjustment block 8.

[0033] Among them, a fixing groove 703 is opened on the top of the moving block 7, a fixing rod 801 is connected to the top of the adjusting block 8, a thread is provided on the outer side of the fixing rod 801 and is meshed with a fixing nut, a slider 701 is connected to one side of the moving block 7, and the cross-sectional profile of the slider 701 cooperates with the cross-sectional profile of the slide groove 501, and the adjusting block 8 and the slider 701 are both T-shaped structures.

[0034] When cutting the plate, the position of the positioning block 802 can be adjusted accordingly according to the length of the plate to be cut. At this time, the fixing nut on the fixing rod 801 can be removed to release the restriction on the fixing rod 801 and the adjusting block 8. Then the fixing rod 801 and the adjusting block 8 can be moved to change the position of the positioning block 802. After moving to the corresponding position, the fixing nut is screwed onto the fixing rod 801 again, so that the fixing nut fixes the fixing rod 801 at the current position, and the adjustment of the position of the positioning block 802 is completed. By setting the slider 701 and the slide groove 501, the moving direction of the moving block 7 can be limited, and by setting the adjustment groove 702 and the adjustment block 8, the moving direction and distance of the positioning block 802 can be limited; Then, as the lifting plate 401 moves downward, it drives the gear plate 4011 to move, and the gear plate 4011 drives the transmission plate 704 to move through the transmission gear 6, so that as the lifting plate 401 moves downward, the moving block 7 drives the positioning block 802 to move upward, so that the positioning block 802 no longer blocks the transmission path of the plate, so that the plate can be sent out of the equipment box after cutting, and the arrangement of the slot 502 can provide a moving space for the transmission plate 704.

[0035] After the cutting is completed, the lifting plate 401 drives the cutter 402 and the pressing block 406 to move up. At this time, the gear plate 4011, the transmission gear 6 and the transmission plate 704 drive the moving block 7 to move down. While the moving block 7 moves down, the electric roller 102 is used to convey the cut plate, so that when the positioning block 802 has not yet moved down to the lowest point, the plate has been sent to the bottom of the positioning block 802, so that the positioning block 802 is against the upper surface of the plate, and then the moving block 7 continues to move down. At this time, the compression groove 803 and the compression spring 804 are set, so that the adjustment block 8 continues to move down and squeeze the compression spring 804, and the positioning block 802 always contacts the top of the plate, on the one hand, avoiding the positioning block 802 from moving down to block the delivery path of the cut plate, on the other hand, avoiding the situation where the adjustment block 8, the transmission plate 704 and the positioning block 802 produce motion interference. After the plate is sent out, the positioning block 802 moves downward under the action of the elastic force of the compression spring 804 to block the delivery path of the next plate, thereby positioning the next plate.

[0036] See also Figure 3 and Figure 5 Among them, two hydraulic rods 4 are installed inside the equipment box 2, the bottom of the hydraulic rods 4 is connected to the lifting plate 401, two fixed blocks 403 are connected to the bottom of the lifting plate 401, a movable groove 404 is opened at the bottom of the fixed block 403, two movable springs 405 are connected inside the movable groove 404, a pressing block 406 is arranged at the bottom of the movable spring 405, and a pressing plate 407 is connected to the bottom of the pressing block 406.

[0037] When shearing the plate, the hydraulic rod 4 drives the lifting plate 401 to move downward, and at the same time stops the rotation of the electric roller 102, so that the cutter 402 at the bottom of the lifting plate 401 shears the plate. At the same time, the lifting plate 401 drives the fixed block 403 to move downward, and then drives the pressing block 406 and the pressing plate 407 to move downward, so that they contact the plate before the cutter 402, and as the lifting plate 401 moves downward, the pressing plate 407 and the pressing block 406 move the spring 405 under the action of the reaction force, so that the movable spring 405 generates elastic force and acts on the pressing block 406, and is transmitted to the pressing plate 407 through the pressing block 406, so as to press and fix the plate, so as to avoid position displacement of the plate during the cutting process and affect the cutting accuracy.

[0038] See also Figure 3 and Fig.10 , wherein a collecting chamber 301 is provided inside the air extraction box 3, a waste box 302 is arranged inside the collecting chamber 301, and the waste box 302 is made of a high-mesh filter screen; an air extraction pump 303 is installed inside the air extraction box 3, and an air suction end of the air extraction pump 303 is communicated with the collecting chamber 301; a cutting groove 3011 is provided on the top of the air extraction box 3, and the cutting groove 3011 corresponds to the position of the cutter 402; ejection grooves 304 are provided on the inner walls on opposite sides of the cutting groove 301, an ejection plate 305 is provided inside the ejection groove 304, an ejection hole 306 is provided inside the ejection plate 305, an ejection rod 307 is penetrated inside the ejection hole 306, one end of the ejection rod 307 is connected to an ejection block 308, and an inclined surface is provided at the end of the ejection block 308, an ejection spring 309 is connected between the ejection block 308 and the ejection plate 305, and the ejection spring 309 is located outside the ejection rod 307.

[0039] During cutting, the cutter 402 cuts into the cutting groove 3011 and squeezes the ejector block 308 open. At this time, the gas inside the collecting chamber 301 is extracted by the vacuum pump 303, so that the air pressure inside the collecting chamber 301 drops and suction is generated. The dust and debris generated by the cutting are sucked into the collecting chamber 301 by the suction force generated by the vacuum pump 303 along with the airflow, and the dust, debris and impurities in the gas are filtered and isolated by the waste box 302. When the ejector block 308 is squeezed open by the cutter 402, the ejector block 308 squeezes the ejector spring 309, so that the ejector spring 309 generates elastic force and acts on the ejector block 308, so that the ejector block 308 is close to the side of the cutter 402. When the cutter 402 moves up, the debris and impurities attached to the surface of the cutter 402 are scraped off by the ejector block 308 to ensure the sharpness of the cutting of the cutter 402.

[0040] See also Figure 3 and Figure 4In the figure, a transmission groove 101 is provided on the top of the workbench 1, and a plurality of evenly distributed electric rollers 102 are provided inside the transmission groove 101. Two fixed plates 103 are connected to the top of the workbench 1. Threaded holes 104 are provided on the fixed plates 103. Threaded rods 105 are meshedly connected inside the threaded holes 104. One end of the threaded rod 105 is connected to a handwheel, and the other end of the threaded rod 105 is connected to a limit plate 106 through a bearing, and the limit plate 106 is located above the electric roller 102.

[0041] Before cutting the plate, in order to ensure that the plate can be correctly transported to the cutter 402, the position of the plate transported on the electric roller 102 can be limited by adjusting the relative distance between the two limit plates 106, and the state of the plate during transportation can be corrected. At this time, the threaded rod 105 can be driven to rotate by the hand wheel, so that the threaded rod 105 drives the limit plate 106 to move under the action of the threaded hole 104, thereby completing the adjustment of the position of the limit plate 106.

[0042] Working principle: Before cutting the plate, in order to ensure that the plate can be correctly transported to the cutter 402, the relative distance between the two limit plates 106 can be adjusted to limit the position of the plate transported on the electric roller 102, and the state of the plate during transportation can be corrected. At this time, the threaded rod 105 can be driven to rotate by the hand wheel, so that the threaded rod 105 drives the limit plate 106 to move under the action of the threaded hole 104, and the position of the limit plate 106 is adjusted. When cutting the plate, the position of the positioning block 802 can be adjusted accordingly according to the length of the plate to be cut. At this time, it can be seen that the fixing rod 801 The fixing nut is removed to release the restriction on the fixing rod 801 and the adjusting block 8. Then the fixing rod 801 and the adjusting block 8 can be moved to change the position of the positioning block 802. After moving to the corresponding position, the fixing nut is screwed onto the fixing rod 801 again, so that the fixing nut fixes the fixing rod 801 at the current position, completing the adjustment of the position of the positioning block 802. Then, through the setting of the slider 701 and the slide groove 501, the moving direction of the moving block 7 can be limited, and through the setting of the adjusting groove 702 and the adjusting block 8, the moving direction and distance of the positioning block 802 can be limited.

[0043] Then the plate is placed on the motorized roller 102 and sent into the equipment box 2 by the motorized roller 102 until it contacts the positioning block 802. Then the lifting plate 401 is driven downward by the hydraulic rod 4, and the rotation of the motorized roller 102 is stopped, so that the cutter 402 at the bottom of the lifting plate 401 shears the plate. At the same time, the lifting plate 401 drives the fixed block 403 downward, and then drives the pressing block 406 and the pressing plate 407 downward, so that they contact the plate before the cutter 402. As the lifting plate 401 moves downward, the pressing plate 407 and the pressing block 406 move the spring 405 under the action of the reaction force, so that the spring 405 An elastic force is generated and acts on the pressing block 406, and is transmitted to the pressing plate 407 through the pressing block 406, so as to press and fix the plate to avoid position displacement of the plate during the cutting process, which affects the cutting accuracy. Then, the gear plate 4011 is driven to move during the downward movement of the lifting plate 401, and the gear plate 4011 drives the transmission plate 704 to move through the transmission gear 6, so that during the downward movement of the lifting plate 401, the moving block 7 drives the positioning block 802 to move upward, so that the positioning block 802 no longer blocks the transmission path of the plate, so that the plate can be sent out of the equipment box after cutting. The arrangement of the slot 502 can provide a moving space for the transmission plate 704.

[0044] After the cutting is completed, the lifting plate 401 drives the cutter 402 and the pressing block 406 to move up. At this time, the gear plate 4011, the transmission gear 6 and the transmission plate 704 drive the moving block 7 to move down. While the moving block 7 moves down, the electric roller 102 is used to convey the cut plate, so that when the positioning block 802 has not yet moved down to the lowest point, the plate has been sent to the bottom of the positioning block 802, so that the positioning block 802 is against the upper surface of the plate, and then the moving block 7 continues to move down. At this time, the compression groove 803 and the compression spring 804 are set, so that the adjustment block 8 continues to move down and squeeze the compression spring 804, and the positioning block 802 always contacts the top of the plate, on the one hand, avoiding the positioning block 802 from moving down to block the delivery path of the cut plate, on the other hand, avoiding the situation where the adjustment block 8, the transmission plate 704 and the positioning block 802 produce motion interference. After the plate is sent out, the positioning block 802 moves downward under the action of the elastic force of the compression spring 804 to block the delivery path of the next plate, thereby positioning the next plate.

[0045] At the same time, during cutting, the cutter 402 cuts into the cutting groove 3011 and squeezes the ejector block 308 open. At this time, the gas inside the collecting chamber 301 is extracted by the vacuum pump 303, so that the air pressure inside the collecting chamber 301 drops and suction is generated. The dust and debris generated by the cutting are sucked into the collecting chamber 301 by the suction force generated by the vacuum pump 303 along with the air flow, and the dust, debris and impurities in the gas are filtered and isolated through the waste box 302. When the ejector block 308 is squeezed open by the cutter 402, the ejector block 308 squeezes the ejector spring 309, so that the ejector spring 309 generates elastic force and acts on the ejector block 308, so that the ejector block 308 is close to the side of the cutter 402. When the cutter 402 moves up, the debris and impurities attached to the surface of the cutter 402 are scraped off by the ejector block 308 to ensure the sharpness of the cutting of the cutter 402.
