Specific embodiments
[0017] Refer to Figures 1 to 4 As shown, the utility model provides a galvanized steel strip cutting and traction device, including: a base 1 and an adjusting screw rod 5. Activity grooves are symmetrically opened on the upper surface of the base 1. The driven roller 2 is movably connected in the activity grooves through bearings. One end of the upper surface of the base 1 is fixedly connected with a cutting assembly 12. The middle of the upper surface of the base 1 is fixedly connected with a fixing frame 10. The upper surface of the fixing frame 10 is fixedly connected with a main hydraulic cylinder 11. The telescopic rod of the main hydraulic cylinder 11 is fixedly connected with a lifting plate 8. At the same time, through grooves are symmetrically opened at both ends of the lifting plate 8. The driving roller 9 is movably connected in the through grooves through bearings. The auxiliary motor 14 is fixedly connected to the outer side surface of the lifting plate 8 near the through grooves through a groove. The auxiliary motor 14 is movably connected to the driving roller 9 through a bearing. Both ends of the lower surface of the lifting plate 8 are respectively fixedly connected with an air jet plate 3 and a cleaning assembly 7. The adjusting screw rod 5 is movably connected in a moving groove 16 opened on the lower surface of the base 1 through a bearing. Lower guiding grooves 15 are symmetrically opened on both sides of the top of the moving groove 16. The main motor 13 is fixedly connected to the outer side surface of the base 1. The main motor 13 is connected to the adjusting screw rod 5 through a coupling. The moving plate 4 is slidably connected in the moving groove 16 and the lower guiding groove 15 through the adjusting screw rod 5 in a screwed manner. Limiting plates 6 are symmetrically connected to both ends of the moving plate 4. At the same time, upper guiding grooves are correspondingly opened on the side surface of the lifting plate 8 at positions opposite to the limiting plates 6.
[0018] In this embodiment, the galvanized steel strip is laid on the upper surface of the driven roller 2. The switch of the main hydraulic cylinder 11 is activated. The telescopic rod of the main hydraulic cylinder 11 pushes the driving roller 9 downward through the lifting plate 8. Then, the driving roller 9 abuts against the surface of the galvanized steel strip through the fastening sleeve. The switch of the main motor 13 is activated. The coupling of the main motor 13 drives the adjusting screw rod 5 to rotate. The adjusting screw rod 5 pushes the corresponding limiting plate 6 to move relatively through the screwed moving plate 4. Then, the surface of the limiting plate 6 can fit the side surface of the galvanized steel strip, reducing the probability of the galvanized steel strip shifting in position during movement. The switch of the auxiliary motor 14 is activated. The auxiliary motor 14 drives the driving roller 9 to rotate synchronously through the coupling. Then, the driving roller 9 can smoothly push the galvanized steel strip to move accordingly. And during the movement of the galvanized steel strip, the valve of the air delivery pipe connected to the air jet plate 3 is opened, and the air flow will spray onto the upper and lower surfaces of the galvanized steel strip through the air jet holes. Then, the surface of the galvanized steel strip can be correspondingly preliminarily cleaned. The cleaning cotton in the cleaning assembly 7 will fit the surface of the galvanized steel strip. Therefore, the surface of the galvanized steel strip can be cleaned for the second time, effectively enhancing the cleanliness of the surface of the galvanized steel strip. When the galvanized steel strip needs to be cut, the switch of the auxiliary hydraulic cylinder in the cutting assembly 12 is activated. The telescopic rod of the auxiliary hydraulic cylinder pushes the cutting knife downward. Then, with the cooperation of the cutting knife and the cutting groove, the cutting process of the galvanized steel strip can be smoothly completed.
[0019] As a preferred embodiment, a plurality of groups of movable grooves are arranged in parallel at equal intervals along the length direction on the upper surface of the base 1. The movable grooves are adapted to the size of the driven roller 2, and the length of the movable grooves is less than the width of the base 1. At the same time, the fixed frame 10 fixedly connected to the upper surface of the base 1 has a U-shaped structure.

Then, it can assist in enhancing the stability of the driven roller 2 during rotation and also assist in reducing the probability of foreign objects falling into the movable grooves.
[0021] As a preferred embodiment, the lifting plate 8 has a rectangular structure. The lifting plate 8 is adapted to the size of the top of the fixed frame 10.

At the same time, the fastening sleeve can be made of soft materials such as soft rubber, which can then assist in enhancing the friction between the driving roller 9 and the galvanized steel strip, ensuring that the driving roller 9 can stably push the galvanized steel strip to move.
[0023] As a preferred embodiment, four groups of upper guiding grooves are symmetrically formed on the surface of the lifting plate 8, and the positions of the four groups of upper guiding grooves correspond one by one to the four groups of lower guiding grooves 15 formed on the surface of the base 1. Both the upper guiding grooves and the lower guiding grooves 15 are rectangular structures, and the through groove is located directly above the corresponding movable groove.
[0024] In this embodiment, as Figure 1 and Figure 2 , the number and positions of the upper guiding grooves and the lower guiding grooves 15 correspond one by one. Subsequently, the moving plate 4 can drive the corresponding limiting plates 6 to move synchronously, so that the distance between the limiting plates 6 on both sides of the base 1 can be conveniently adjusted, ensuring that galvanized steel strips of different sizes can move stably and reducing the probability of continuous position deviation of the galvanized steel strip.
[0025] As a preferred embodiment, the moving groove 16 formed on the lower surface of the base 1 is rectangular in structure, and the moving plate 4 slidingly connected in the moving groove 16 is U-shaped. The bent portions at both ends of the moving plate 4 are slidingly connected in the corresponding lower guiding grooves 15. At the same time, the two limiting plates 6 fixedly connected to both ends of the moving plate 4 are both semi-cylindrical structures, and the limiting plates 6 are slidingly connected in the upper guiding grooves.
[0026] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 , the arc-shaped structure of the limiting plate 6 can effectively reduce the contact area between the limiting plate 6 and the side surface of the galvanized steel strip, which can then assist in reducing the frictional resistance on the side surface of the galvanized steel strip and reducing the probability of damage to the side surface of the galvanized steel strip.
[0027] As a preferred embodiment, there are two sets of jet plates 3 and cleaning assemblies 7 respectively. One set of jet plates 3 is fixedly connected to the lifting plate 8, and the other set of jet plates 3 is fixedly connected to the opposite positions on the upper surface of the base 1. One set of cleaning assemblies 7 is fixedly connected to the lifting plate 8 by a buckle, and the other set of cleaning assemblies 7 is fixedly connected to the opposite positions on the upper surface of the base 1 by a buckle. At the same time, the end face of the jet plate 3 is a right trapezoidal structure, and multiple jet holes are evenly formed on the inclined surface of the jet plate 3.
[0028] In this embodiment, as Figure 1 、 Figure 3 and Figure 4, the jet plate 3 and the cleaning component 7 are arranged such that while the device is towing the galvanized steel strip, it can also clean the surface of the galvanized steel strip accordingly, avoiding debris remaining on the surface of the galvanized steel strip, ensuring the cleanliness of the galvanized steel strip. At the same time, the cleaning component 7 is composed of a mounting plate and cleaning cotton, and the mounting plate is fixedly connected to the surfaces of the lifting plate 8 and the base 1 through buckles.
[0029] As a preferred embodiment, the cutting component 12 is composed of a positioning frame, a secondary hydraulic cylinder, and a cutting knife. The upper surface of the positioning frame is fixedly connected to the secondary hydraulic cylinder, and the telescopic rod of the secondary hydraulic cylinder is fixedly connected to the cutting knife. Both ends of the cutting knife are slidably connected in the guiding grooves correspondingly opened on both sides of the positioning frame. At the same time, a cutting groove is correspondingly opened on the upper surface of the base 1 at a position opposite to the cutting knife.
[0030] In this embodiment, as Figure 1 and Figure 3 , the sizes of the guiding grooves and both ends of the cutting knife are adapted to each other, thereby being able to assist in enhancing the stability of the cutting knife during movement. Moreover, the opening of the cutting groove can effectively reduce the probability of accidental damage to the cutting edge of the cutting knife.
[0031] Through the cooperation of the lifting plate 8, the driving roller 9, the driven roller 2, the moving plate 4, and the limiting plate 6, the galvanized steel strip cutting and towing device of the present utility model enables the device to perform corresponding towing processing on galvanized steel strips of different sizes, can effectively reduce the probability of the galvanized steel strip shifting in position, and can also perform corresponding cutting processing on the galvanized steel strip, enhancing the overall practicality of the device.
