[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0025] A galvanized steel strip cutting device includes a support frame 1 for placing the galvanized steel strip, a fixing frame 2 fixed to one side of the top of the support frame 1, a controller on the front of the fixing frame 2, a cylinder 3 embedded in the top of the fixing frame 2, a strip frame 4 that slides within the fixing frame 2 and whose piston rod is fixed to the U-shaped frame, and a cutter 5 for cutting the galvanized steel strip fixed to the bottom of the strip frame 4, a groove for cooperating with the cutter 5 on the support frame 1, and fixing slots on the other side of both the front and back of the support frame 1. 6. The support frame 1 is equipped with an anti-deviation component that works with the galvanized steel strip. The anti-deviation component includes a first electric slide rail slide 8 fixed below the support frame 1 and having built-in positive and negative threaded rods. Each set of fixing slots 6 has a pressure frame 7 slidably arranged to press and position the galvanized steel strip. The first electric slide rail slide 8 is fixed to the pressure frame 7 by symmetrically arranged first slides. Each set of pressure frames 7 has a pressure plate 9 slidably arranged in the strip groove. A vacuum suction cup 10 is fixed to the inner side of the bottom of the pressure plate 9. An air pump 1 is fixed to the bottom of the support frame 1. 8. The air inlet of the air pump 18 is connected to a three-way pipe 17. Both ends of the three-way pipe 17 away from the air pump 18 are connected to the vacuum suction cup 10. The bent ends at the bottom of the front and back sides of the three-way pipe 17 are fixed to the bottom of the pressure frame 7. The bent ends at the top of the front and back sides of the three-way pipe 17 are fixed to the pressure plate 9. The vertical ends of the front and back sides of the three-way pipe 17, as well as the front and back sides of the bottom, are all telescopic tube structures. The strip frame 4 is equipped with an adjustable pressing structure that works in conjunction with the pressure plate 9 and the vacuum suction cup 10. The adjustable pressing structure includes... The system includes a second electric slide rail 12 fixed to the strip frame 4 and having built-in positive and negative threaded rods. A shift frame 13 is fixed inside the second electric slide rail 12 through symmetrically arranged second slides. Multiple sets of T-shaped shift rods 14 are inserted sequentially along the left and right direction at the top of each set of shift rods 13. A first spring 15 is wound around each set of T-shaped shift rods 14. The two ends of each set of first springs 15 are fixed to the protruding end of the T-shaped shift rod 14 and the shift frame 13. A push plate 16 located above the pressure plate 9 is fixed to the bottom end of multiple sets of T-shaped shift rods 14.

[0026] Specifically, this invention, by setting up an anti-deviation component, utilizes the first electric slide rail 8 to change the position of the pressure frame 7, so that the pressure frame 7 can be used to squeeze and position the side of the galvanized steel strip. The adjustable pressing structure design utilizes the second electric slide rail 12 to change the position of the shifting frame 13, so that it can be moved above the pressure plate 9. The downward force of the cylinder 3 drives the push plate 16 to synchronously change the positions of the pressure plate 9 and the vacuum suction cup 10, and the cutter 5 moves downward synchronously to press the top of the galvanized steel strip. As the cutter 5 moves downward, the pressing force can be increased. Simultaneously, the air pump 18 can quickly extract the air from the vacuum suction cup 10, so that it can be quickly adsorbed onto the top of the galvanized steel strip for adsorption and positioning. Employing multiple positioning methods, it can quickly position the galvanized steel strip according to its size, effectively preventing displacement of the galvanized steel strip during cutting, improving the overall anti-deviation effect of the device, and thus improving the cutting accuracy of the galvanized steel strip.

[0027] The top of the pressure frame 7, which is far apart from each other, is fixed with a second spring 11 by a protrusion, and the bottom end of the second spring 11 is fixed to the pressure plate 9.

[0028] Specifically, by utilizing the elastic rebound of the second spring 11, a continuous elastic support force is provided to the pressure plate 9, so that the pressure plate 9 can maintain a certain height with the support frame 1 when not in use, making it convenient for the galvanized steel strip to move from one side of the support frame 1 to the cutter 5.

[0029] A slide bar 23 is fixed on the right side of the push plate 16, and a positioning slide 24 is provided inside the shift frame 13 for inserting the slide bar 23.

[0030] Specifically, by utilizing the sliding of the slider 23 and the positioning slide 24, and by ensuring that the slider 23 has a certain height, the direction of movement of the push plate 16 can be limited, thus preventing the push plate 16 from tilting during movement and affecting the pressing effect of the push plate 16 on the pressure plate 9.

[0031] An L-shaped baffle 22 with its bottom attached to the support frame 1 is fixed on the left side of the pressure frame 7. The inner side of the L-shaped baffle 22 and the inner side of the pressure frame 7 are on the same horizontal plane.

[0032] Specifically, the design of the L-shaped baffle 22 can extend the overall width of the pressure frame 7 and increase its contact area with the side of the galvanized steel strip, thereby improving the pressing stability of the galvanized steel strip and preventing displacement.

[0033] The bottom of the support frame 1 is fixed with a positioning frame 20 fixed on the three-way pipe 17. The end of the three-way pipe 17 near the air pump 18 is connected to an auxiliary branch pipe 19. A solenoid valve is installed on the auxiliary branch pipe 19. Each set of pressure plates 9 is inserted with a vertical plate 21. The two ends of the vertical plate 21 are fixed in the preset strip groove on the pressure frame 7.

[0034] Specifically, the design of the positioning frame 20 can fix the position of the three-way pipe 17 near the air pump 18 so that the lower telescopic end can be stably and freely extended and retracted. At the same time, the design of the auxiliary branch pipe 19 and the solenoid valve can control the closed state of the three-way pipe 17 so that external air can be quickly injected into the three-way pipe 17 to quickly release the adsorption state of the vacuum suction cup 10, which facilitates the movement of the cut galvanized steel strip. Meanwhile, the design of the upright plate 21 can slide and limit the pressure plate 9, improving its movement stability and preventing deviation. The specific usage process is as follows: The user places the galvanized steel strip to be cut on the support frame 1. At this time, the two sets of moving frames 13 are in the center position on the support frame 1. Then, the user opens the first electric slide rail 8 with built-in positive and negative threaded rods through the controller. The first slide rail with reverse displacement on it can drive the two sets of pressure frames 7 to move in opposite directions until the pressure frames 7 are in contact with the side of the galvanized steel strip and quickly squeeze and position the side. Then, the user opens the second electric slide rail 12 with built-in positive and negative threaded rods through the controller. The first electric slide rail 8 and the second electric slide rail 12 are relatively common drive structures with motors and threaded rods. The specific principle will not be elaborated here. At this time, the second electric slide rail 12 can drive the two sets of moving frames 13 to move in opposite directions through the second slide rail on it until they move above the pressure plate 9. At this time, the user opens the cylinder 3 through the controller, which can drive the strip frame 4, the cutter 5, the moving frames 13 and the push plate 16 to move down synchronously. Under pressure, the pressure plate 9 and vacuum suction cup 10 can move down synchronously, and the first spring 15 can be stretched synchronously until the bottom of the vacuum suction cup 10 contacts the top of the galvanized steel strip, pressing and positioning the top of it. At the same time, the air pump 18 is turned on synchronously, which can quickly draw the vacuum suction cup 10 into a negative pressure state, and make it quickly adsorb onto the galvanized steel strip for adsorption and fixation. As the strip frame 4 continues to move down, the distance between the push plate 16 and the top of the transfer frame 13 can be continuously reduced, thereby increasing the stretching length of the first spring 15. At this time, the elastic rebound of the first spring 15 is used to further improve the pressing and fastening. At this time, the downward-moving cutter 5 can cut the galvanized steel strip. After the cutting is completed, the solenoid valve is opened, and the outside air enters the three-way pipe 17 and the vacuum suction cup 10 through the auxiliary pipe 19, which can release the adsorption state of the galvanized steel strip. Then, the pressure plate 9, vacuum suction cup 10 and pressure frame 7 are driven to reset, and the galvanized steel strip can be removed.This invention, through the inclusion of an anti-deviation component and the use of a first electric slide rail 8, allows for the repositioning of the pressure frame 7, enabling it to press and position the galvanized steel strip along its sides. Furthermore, the adjustable pressing structure, utilizing a second electric slide rail 12, allows for the repositioning of the shifting frame 13, moving it above the pressure plate 9. The downward force of the cylinder 3 drives the push plate 16 to synchronously change the positions of the pressure plate 9 and the vacuum suction cup 10, while the cutter 5 moves downwards simultaneously to press the top of the galvanized steel strip. As the cutter 5 moves downward, the pressing force can be increased. Simultaneously, the air pump 18 rapidly extracts air from the vacuum suction cup 10, allowing it to be quickly adsorbed onto the top of the galvanized steel strip for positioning. Employing multiple positioning methods, the device can quickly position the galvanized steel strip according to its size, effectively preventing displacement during cutting and improving the overall anti-deviation effect of the device, thus enhancing the cutting accuracy. The elastic rebound of the second spring 11 continuously provides elastic support to the pressure plate 9. This design ensures that the pressure plate 9 maintains a certain height relative to the support frame 1 when not in use, facilitating the movement of the galvanized steel strip from one side of the support frame 1 to the cutter 5. The sliding of the slide bar 23 and the positioning slide 24, with the slide bar 23 having a certain height, limits the movement direction of the push plate 16, preventing it from tilting during movement and affecting its pressing effect on the pressure plate 9. The L-shaped baffle 22 extends the overall width of the pressure frame 7, increasing its contact area with the side of the galvanized steel strip, thereby improving the pressure on the galvanized steel strip. The design of the positioning frame 20 ensures the stability of the pressing action and prevents deviation. It also secures the three-way pipe 17 near the air pump 18, allowing for stable and free extension and retraction of the lower telescopic end. Furthermore, the design of the auxiliary branch pipe 19 and the solenoid valve controls the closed state of the three-way pipe 17, enabling rapid injection of external air into it and quickly releasing the suction of the vacuum suction cup 10. This facilitates the movement of the cut galvanized steel strip. Additionally, the design of the upright plate 21 provides sliding limit for the pressure plate 9, improving its movement stability and preventing deviation.

[0035] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
