Description

Technical Field

[0001] This utility model relates to the field of steel strip slitting machines, specifically to a slitting machine for stainless steel strips. Background Technology

[0002] Stainless steel strip is a narrow and long steel plate that can meet the production needs of metal or mechanical products. Because the width of stainless steel strip after factory production is relatively wide, it needs to be slitting to obtain the required width of stainless steel strip. However, existing slitting machines generally do not have a guiding and anti-deviation function. During cutting, the high-speed rotating blades come into contact with the stainless steel strip, so the position of the stainless steel strip is prone to deviation, affecting the accuracy of slitting.

[0003] Chinese patent CN221639641U discloses a slitting machine for stainless steel strip with anti-deviation design. This slitting machine limits both ends of the stainless steel strip during feeding and simultaneously presses down to fix the strip at the exit end, effectively ensuring the stability of the stainless steel strip during cutting and preventing positional deviation, thus guaranteeing slitting accuracy. However, this slitting machine also has the following problems: the width of the anti-deviation guide component needs to be adjusted in advance according to the size of the steel strip, which is time-consuming and labor-intensive. Furthermore, the stainless steel strip must be manually moved under the blade before slitting, which poses a safety hazard and may result in accidental arm cuts. Therefore, its practicality is limited. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned defects and provide a slitting machine for stainless steel strip.

The first bracket and the second bracket are connected by two connecting rods. A first rolling shaft is movably installed between the first support base and the second support base. An adjustable first support member and a second support member are movably installed on the first support base and the second support base, respectively. A second rolling shaft that cooperates with the first rolling shaft is movably installed between the first support member and the second support member. Both the first rolling shaft and the second rolling shaft are rotated by a drive mechanism. A plurality of first rollers are movably installed between the first bracket and the second bracket. A guide frame is installed above the first rollers on the first bracket and the second bracket. Limiting components are installed on both inner sides of the guide frame. A guide component is movably installed at the end of the first support base and the second support base near the guide frame.

[0006] Furthermore, both the first support base and the second support base are provided with adjustment grooves, and the first support member and the second support member are both installed on the adjustment grooves, so that the positions of the first support member and the second support member can be flexibly adjusted according to actual needs, further enhancing the adaptability of the slitting machine to stainless steel strips of different widths and thicknesses.

[0007] Furthermore, both the first support base and the second support base are equipped with a first limiting block, and each first limiting block is provided with an adjusting rod that cooperates with the first support member and the second support member. By setting the first limiting block and the adjusting rod, the first support member and the second support member can be accurately adjusted to ensure the matching accuracy between the second rolling shaft and the first rolling shaft, thereby better adapting to steel strips of different specifications and improving the slitting quality.

[0008] Furthermore, the drive mechanism includes a drive motor, a first gear, a drive chain, a second gear, a third gear, and a fourth gear. One end of the drive motor extends to have a first drive portion that engages with the first gear. The drive chain is fitted onto the first gear and the second gear.

One end of the first rolling shaft extends outward to have a second drive portion that engages with the second gear and the third gear. One end of the second rolling shaft extends outward to have a third drive portion that engages with the fourth gear. By providing the drive motor, a stable power output can be provided to the first rolling shaft and the second rolling shaft.

[0009] Furthermore, keyways are provided between the first drive unit and the first gear, between the second drive unit and the second gear, and between the third drive unit and the fourth gear. By providing keyways, the connection between the drive unit and the gears becomes more stable and reliable, effectively transmitting torque and preventing slippage or loosening during transmission, thus ensuring the stability of the drive mechanism and the normal operation of the slitting machine.

[0010] Furthermore, a drive key is fastened to the keyway, which strengthens the connection between the drive unit and the gear, improves the reliability and stability of the transmission, and ensures that the drive mechanism can continuously and stably provide power to the rolling shaft during the operation of the slitting machine.

[0011] Furthermore, the guide assembly includes a movable shaft, a third connector, a fourth connector, and a second roller.

[0012] Furthermore, a guide wheel is installed between the first support base and the second support base, below the second roller. The guide wheel is provided with several horizontally arranged slots. By setting the slots on the guide wheel, it can cooperate with the edge of the steel strip to prevent the steel strip from swaying left and right during the slitting process, thereby further improving the slitting accuracy and stability, and also helping to protect the edge quality of the steel strip.

[0013] Furthermore, the limiting component includes a hydraulic cylinder, a hydraulic rod, and a limiting block. One end of the hydraulic rod is movably connected to the hydraulic cylinder, and the other end of the hydraulic rod is connected to the limiting block. The position of the limiting block can be precisely adjusted according to the width of the steel strip and the slitting requirements to ensure that the steel strip remains in the correct position during the slitting process, thereby improving the accuracy and quality of slitting.

[0014] Furthermore, both the first bracket and the second bracket have several adjustment keys on one side for adjusting the first roller.

[0015] The beneficial effects of this invention are as follows: By movably installing adjustable first and second support members on the first and second support seats, the position of the corresponding second rolling shaft can also be adjusted. This allows for flexible adjustment of the spacing and relative position between the two rolling shafts according to stainless steel strips of different widths and thicknesses, greatly enhancing the slitting machine's applicability to various specifications of steel strips. Several first rollers installed between the first and second supports assist in the smooth movement of the steel strip, reducing frictional resistance between the steel strip and the equipment. Limiting components installed on both inner sides of the guide frame precisely limit the position of the steel strip during the slitting process, preventing deviation or offset, ensuring consistent slitting width, and improving slitting accuracy. Furthermore, the guide components guide the steel strip, ensuring it maintains the correct direction when entering the slitting area, guaranteeing the accuracy and stability of the slitting operation.

This enhances the slitting machine's adaptability to stainless steel strips of varying widths and thicknesses. Both the first and second support seats are equipped with first limiting blocks, each with an adjusting rod that engages with the first and second support members. By using these limiting blocks and adjusting rods, the first and second support members can be accurately adjusted, ensuring precise alignment between the second and first rolling shafts. This better accommodates steel strips of different specifications and improves slitting quality.

[0024] The drive mechanism includes a drive motor, a first gear, a drive chain, a second gear, a third gear, and a fourth gear. One end of the drive motor extends to a first drive section that meshes with the first gear. The drive chain is fitted onto the first and second gears.

One end of the first rolling shaft extends outward to a second drive section that meshes with the second and third gears. One end of the second rolling shaft extends outward to a third drive section that meshes with the fourth gear. The drive motor provides stable power output to both the first and second rolling shafts. Keyways are provided between the first drive section and the first gear, between the second drive section and the second gear, and between the third drive section and the fourth gear. These keyways ensure a more secure and reliable connection between the drive section and the gears, effectively transmitting torque and preventing slippage or loosening during transmission, thus guaranteeing the stability of the drive mechanism and the normal operation of the slitting machine. A drive key is fastened to the keyway, which strengthens the connection between the drive unit and the gear, improves the reliability and stability of the transmission, and ensures that the drive mechanism can continuously and stably provide power to the rolling shaft during the operation of the slitting machine.

[0025] The guiding assembly includes a movable shaft, a third connector, a fourth connector, and a second roller. The movable shaft is installed between the first support base and the second support base. The second roller is installed at one end of the third and fourth connectors, and the other ends of the third and fourth connectors are movably mounted on the movable shaft, allowing the second roller to flexibly adapt to the direction of the steel strip and effectively guide it.

The position of the limiting block can be precisely adjusted according to the width of the steel strip and the slitting requirements to ensure that the steel strip remains in the correct position during the slitting process, thereby improving the accuracy and quality of slitting.

[0027] The working principle of this utility model embodiment is as follows:

[0028] 1. Steel belt conveyor and positioning

[0029] The stainless steel strip to be slit is placed on the first roller, whose tension can be adjusted using the adjustment key. Simultaneously, the limiting assembly above the guide frame, driven by a hydraulic cylinder, adjusts the position of the limiting blocks according to the strip width, limiting the strip from both sides to ensure it does not shift left or right during slitting and is accurately positioned within the working area of ​​the slitting machine.

[0030] 2 steel belt guide

[0031] Before entering the slitting area, the steel strip passes through a guide assembly. The second roller in the guide assembly is mounted between the first and second supports via a movable shaft, a third connector, and a fourth connector, allowing it to flexibly adapt to the direction of the steel strip and provide initial guidance. Furthermore, a transverse groove is provided on the guide wheel below the second roller, engaging with the edge of the steel strip to further prevent strip swaying and ensure that the steel strip enters the slitting area along a predetermined path, improving slitting accuracy and stability.

[0032] 3. Slicing operation:

[0033] The first and second support members on the first and second support seats can be positioned on the adjusting groove via adjusting rods and first limiting blocks, thereby adjusting the distance and relative position between the second and first rolling shafts to accommodate steel strips of different thicknesses. The drive motor in the drive mechanism drives the first gear to rotate via the first drive unit. The first gear drives the second gear to rotate via a drive chain. The second and third gears are coaxial, and the third gear meshes with the fourth gear, thus driving the first and second rolling shafts to rotate respectively. The two rolling shafts rotate in opposite directions, slitting the steel strip that enters between them. Because the drive mechanism is connected by keyways and drive keys, it can stably transmit torque, ensuring the stability and reliability of the slitting process.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
