In the traditional color-coated steel plate cutting process, conveyor rollers are used to transport them, which is inconvenient for rapid positioning. In addition, since the conveying method of the conveyor rollers is prone to slipping, it is not convenient to control the conveying distance through mechanical automatic control methods. Therefore, it is necessary to manually open or close the conveyor rollers to ensure that it can perform fixed-length cutting operations.

When the first air pump 706 is turned off, the elastic potential energy of the spring 70124 causes the telescopic rod 70125 to contract and drives the air guide tube 708 to move upward, causing the suction cup 709 to detach from the surface of the color-coated steel plate.

[0029] The shear assembly 12 includes a linkage block 1201; illustratively, Figure 8 shown.

[0030] The linkage block 1201 is fixedly connected to the output ends of the two groups of first cylinders 11.

[0031] A pressure roller 1203 is installed on one side wall of the linkage block 1201, and the pressure roller 1203 is movably fitted with the surface of the color-coated steel plate. Two groups of sliders 1211 are symmetrically arranged at the bottom end of the linkage block 1201, and the two sliders 1211 are movably fitted with the two groups of slide grooves 301 respectively; A transmission groove 1204 is provided in the linkage block 1201, and two groups of second cylinders 1205 are installed in the transmission groove 1204.

[0032] Several groups of longitudinal cutting knives 1208 are detachably mounted on the bottom end of the linkage block 1201; Specifically, by setting up several groups of longitudinal cutting knives 1208, the linkage block 1201 can be moved while the color-coated steel plate is cut longitudinally. The number of longitudinal cutting knives 1208 and the distance between each two groups of longitudinal cutting knives 1208 can be adjusted as needed through the detachable installation to meet the cutting requirements of different widths.

[0033] A dust guide tube 1209 is provided at the bottom end of the linkage block 1201, and a plurality of dust suction tubes 1210 are connected to the dust guide tube 1209, and the input ends of the plurality of dust suction tubes 1210 are all facing the longitudinal cutting knife 1208. A dust collecting chamber is provided in the linkage block 1201, and the dust collecting chamber is connected to the dust guide tube 1209. A second air pump 1212 is installed on the linkage block 1201, and the air inlet end of the second air pump 1212 is connected to the inside of the dust collecting chamber; Specifically, negative pressure is formed in the dust collecting chamber through the second air pump 1212, so that the debris produced by shearing enters the dust guide pipe 1209 along with the air through the dust suction pipe 1210, and finally enters the dust collecting chamber for centralized treatment.

[0034] The working principle of the quick positioning shearing device for color-coated steel plate processing proposed by the present invention is as follows: One end of the color-coated steel plate is pushed onto the workbench 1 after passing through the guide roller 2, and is limited by two sets of limit plates 3. The threaded rod 5 is driven to rotate by the motor 6, so that the first column 701 drives the positioning assembly 7 to move to one end of the color-coated steel plate, and the air is driven into the telescopic airbag 70122 through the inflation tube 70123 by the first air pump 706, so that the telescopic airbag 70122 expands and stretches, thereby stretching the telescopic rod 70125 and driving the mounting plate 70121 located below it to move. The plurality of suction cups 709 are moved downward, thereby causing the air guide tube 708 to drive the suction cups 709 to move downward and adhere to the surface of the color-coated steel plate. The first air pump 706 forms a negative pressure at the bottom ends of the plurality of suction cups 709, and the plurality of suction cups 709 adsorb the color-coated steel plate to achieve adsorption and positioning thereof. When the first air pump 706 is turned off, the elastic potential energy of the spring 70124 causes the telescopic rod 70125 to contract and drive the air guide tube 708 to move upward, thereby causing the suction cups 709 to separate from the surface of the color-coated steel plate.

[0035] The positioning assembly 7 is driven by the motor 6 to move one end of the color-coated steel plate to the shearing assembly 12, and the suction cup 709 is separated from the color-coated steel plate by closing the first air pump 706. The threaded rod 5 is driven by the motor 6 to rotate in the opposite direction, so that the first column 701 drives the positioning assembly 7 to move away from the shearing assembly 12, and the distance between the shearing assembly 12 and the positioning assembly 7 is detected by the infrared transmitter 7010 and the infrared receiver 1202. When the distance between the two reaches a preset value, the motor 6 is closed, and the color-coated steel plate is adsorbed and positioned by the suction cup 709.

[0036] The shearing assembly 12 is driven to move by two groups of first cylinders 11, so that the linkage block 1201 moves and at the same time drives the longitudinal cutting knife 1208 to cut the color-coated steel plate longitudinally. The distance between the shearing assembly 12 and the positioning assembly 7 is detected by the infrared transmitter 7010 and the infrared receiver 1202. When the shearing assembly 12 moves close to the positioning assembly 7 and the two are in contact, the transverse knife holder 1206 is driven to move downward by two groups of second cylinders 1205, so that the transverse cutting knife 1207 moves downward to cut the color-coated steel plate transversely. During the shearing process, a negative pressure is formed in the dust collecting chamber by the second air pump 1212, so that the debris produced by shearing enters the dust guide pipe 1209 along with the air through the dust suction pipe 1210, and finally enters the dust collecting chamber for centralized treatment.

[0037] After the shearing is completed, the shearing component 12 is driven to reset through the two groups of first cylinders 11, and one end of the unsheared color-coated steel plate is adsorbed through the positioning component 7, and driven to move in the direction close to the shearing component 12, and the finished color-coated steel plate that has been sheared is pushed to move toward the unloading platform 15. During the movement, the debris attached to the surface of the sheared product is further adsorbed through the dust suction pipe 1210 to improve the cleanliness of the sheared product. When the first column 701 moves, the tooth plate 7013 engages with the gear 19, so that the tooth plate 7013 drives the gear 19 to rotate when it moves, so that the worm 18 drives the worm wheel 16 to rotate, thereby driving the unloading platform 15 to rotate, so that the finished product after shearing is pushed onto the unloading platform 15 and automatically unloaded as the unloading platform 15 rotates.

[0038] By setting up several groups of detachable installations, the number of longitudinal cutting knives 1208 and the distance between every two groups of longitudinal cutting knives 1208 can be adjusted as needed to meet cutting requirements of different widths.

[0039] Based on the above-mentioned fast positioning shearing device for color-coated steel plate processing, the embodiment of the present invention further proposes a shearing method for the shearing device. Exemplarily, the shearing method includes: Push one end of the color-coated steel plate onto the workbench after passing through the guide roller; Turn on the motor, the threaded rod rotates, and the first column drives the positioning assembly to move to one end of the color-coated steel plate; Turn on the first air pump to expand and stretch the telescopic airbag, so that the air guide tube drives the suction cup to move downward and adhere to the surface of the color-coated steel plate. At the same time, the first air pump forms negative pressure at the bottom of the plurality of groups of suction cups, so that the color-coated steel plate is adsorbed by the plurality of groups of suction cups; Turn on the motor, the threaded rod rotates, so that the positioning assembly drives one end of the color-coated steel plate to move to the shearing assembly, and the color-coated steel plate is quickly positioned; The first air pump is turned off to separate the positioning component from one end of the color-coated steel plate, and the motor is turned on. The positioning component moves to a preset distance from the shearing component, and the infrared transmitter and the infrared receiver detect the distance between the two. When the distance value reaches the preset value, the motor is automatically turned off, and the first air pump is turned on to adsorb and limit the color-coated steel plate; The two first cylinders are turned on, and the shearing assembly moves toward the positioning assembly.
