Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide a device and a method of using a roller to replace a fixed-length shear roller to solve the problems existing in the above-mentioned prior art. The device has a simple structure and is easy to use. It effectively solves the problem that the roller is easy to break and effectively improves the stability and operational reliability of the equipment.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1

[0034] This embodiment provides a device that uses a roller 3 to replace the fixed-length shearing roller 9. Figures 1 to 4 As shown, the guard plate 1 is arranged outside the original disc roller 9 position, including: a plurality of box-type grooves 2 and a plurality of rollers 3, each box-type groove 2 is arranged along the length direction of the guard plate 1, and the top opening of the box-type groove 2 is connected to the top surface of the guard plate 1; one roller 3 is rotatably connected to one box-type groove 2, and the roller 3 can be detachably fixedly connected to the box-type groove 2, and the top section of the roller 3 is higher than the top surface of the guard plate 1, so that the roller 3 can be stably installed in the box-type groove 2 and located at the original guard plate 1 position outside the original disc roller 9, assuming the function of the original disc roller 9. The roller 3 is higher than the top surface of the guard plate 1, and can effectively contact with the steel plate to realize the support and conveying functions. The box-type trough 2 is arranged along the length direction of the guard plate 1 and the top opening is connected to the top surface of the guard plate 1, which is convenient for the installation and maintenance of the roller 3 and also creates favorable conditions for the smooth passage of the steel plate on the device. During maintenance, it is only necessary to remove the roller 3 from the box-type trough 2, so as to achieve online rapid replacement and effectively control the equipment accident time caused by the breakage of the disc roller 9 during the production process. Through operation observation, the operation is stable and the expected goals of output and benefit are achieved.

[0035] In a preferred solution of the present embodiment, the box-type trough 2 also includes a first support plate 4, a first nut 5, a second support plate 6 and a second nut 7. A first mounting groove 8 is provided on the top of the first support plate 4, and a second mounting groove is provided on the top of the second support plate 6. The first support plate 4 and the second support plate 6 are arranged in parallel. The first end of the rotating shaft of the roller 3 passes through the first mounting groove 8 and is threadedly connected to the first nut 5, and the second end of the rotating shaft of the roller 3 passes through the second mounting groove and is threadedly connected to the second nut 7.

[0036] In a preferred solution of this embodiment, the roller 3 is a rubber roller 3, and the rubber roller 3 has good flexibility and elasticity. On the one hand, this enables the rubber roller 3 to better fit the surface of the steel plate when in contact with the steel plate, increase the friction force, ensure the stability of the steel plate during the transmission process, and prevent it from slipping. On the other hand, the rubber roller 3 is relatively soft and can play a certain buffering and protective role on the steel plate, avoiding scratches and other damages to the surface of the steel plate caused by hard contact, thereby improving the quality of the product; on the other hand, it has elastic buffering, which effectively reduces the height adjustment accuracy requirements of the roller 3.

[0037] In a preferred solution of this embodiment, the top section of the roller 3 is 5-10 mm higher than the top surface of the guard plate 1. The top section of the roller 3 is limited to a specific range of 5-10 mm higher than the top surface of the guard plate 1, which can ensure that the roller 3 is in full contact with the steel plate and provides sufficient support force to ensure the smooth transportation of the steel plate during the cut-to-length process. This height range not only avoids the problem of interference with peripheral equipment caused by the roller 3 being too high, but also ensures that the roller 3 can effectively assume the function of replacing the disc roller 9 to support and transport the steel plate, thereby optimizing the working performance of the entire device.

[0038] In a preferred solution of this embodiment, a plurality of first gaskets and a plurality of second gaskets are further included. The first gasket and the second gasket are respectively used to be placed in the first and second mounting grooves to adjust the relative position between the top cut surface of the roller 3 and the top surface of the support surface. The arrangement of the first gasket and the second gasket provides a means for accurately adjusting the height of the roller 3. Gaskets of different thicknesses can be used in combination according to actual needs, thereby adjusting the relative position between the top cut surface of the roller 3 and the top surface of the guard plate 1, so that the height of the roller 3 can better adapt to the processing requirements of steel plates of different specifications. This precise adjustment can ensure that the steel plate maintains good flatness during transportation and improve the processing accuracy and product quality of the cut-to-length shear.

[0039] In a preferred solution of this embodiment, the number of the box-type slots 2 is four, and the four box-type slots 2 are evenly arranged in the length direction of the guard plate 1. The number of the box-type slots 2 is set to four and evenly distributed in the length direction of the guard plate 1, which can provide uniform support for the steel plate in the width direction. In this way, problems such as warping or deviation of the steel plate during transportation due to uneven support can be avoided, and the steel plate is always in a stable state, which is particularly suitable for the cut-to-length operation of long-sized steel plates, and improves the stability and accuracy of the entire processing process.

[0040] In a preferred solution of this embodiment, the axis center lines of the rollers 3 are collinearly arranged, and the axis center lines of the rollers 3 are collinearly arranged, which ensures the stability and consistency of the entire device in supporting and conveying the steel plate. This makes the steel plate evenly stressed on the multiple rollers 3, and can be conveyed in a straight line and smoothly, without causing the steel plate to shake or deviate due to inconsistent axis center lines of the rollers 3, ensuring the smooth execution of the cut-to-length operation, improving the processing accuracy, and being conducive to improving product quality and production efficiency.

[0041] Embodiment 2

[0042] The present invention also provides a method for using the device as described above, which uses the support roller 3 instead of the fixed-length shearing disc roller 9, comprising the following steps:

[0043] Equipment installation and inspection

[0044] First, the guard plate 1 of the disc roller 9 is modified to open a box-type groove 2 corresponding to the size of the roller 3;

[0045] Put the roller 3 into the box-type groove 2, and make the roller 3 15-10mm higher than the guard plate by adding or removing the first gasket and the second gasket. One end of the roller 3 is fixed to the first mounting groove 8 on the top of the first support plate 4 through the first nut 5, and the other end is fixed to the second mounting groove on the top of the second support plate 6 through the second nut 7;

[0046] The guard plate 1 is still installed at the original position outside the original disc roller 9 to ensure that the guard plate 1 is installed firmly and horizontally. During the installation process, the installation accuracy is guaranteed according to the design requirements to prevent the guard plate 1 from tilting or shaking and affecting subsequent use.

[0047] Before it is officially put into use, the entire device is thoroughly inspected to ensure that all components are firmly connected, that the roller 3 rotates flexibly without jamming or abnormal noise, and that all components are not damaged or improperly installed.

[0048] Steel plate delivery preparation

[0049] According to the thickness, width and other specifications of the steel plate to be processed, confirm whether the device is suitable for the steel plate of this specification, and check whether the roller 3 device can withstand the weight of the steel plate and various forces during operation.

[0050] If necessary, perform routine preparation work such as preheating and lubrication on the entire cut-to-length equipment and its accessories to ensure a good operating environment for the equipment.

[0051] Steel plate conveying operation

[0052] The steel plate to be cut to length is transported to the location of the device, so that the steel plate contacts the roller 3. The roller 3 relies on the good friction of its rubber material (if a rubber roller 3 is selected) to ensure that the steel plate can move steadily and smoothly on the roller 3. The rollers 3 work together to ensure that the steel plate is in a flat and straight state during the conveying process, avoiding the swing and deviation of the steel plate, and providing conditions for the smooth operation of the cut to length operation.

[0053] The steel plate is smoothly processed by the cut-to-length shear with the assistance of the roller 3. During the whole process, the roller 3 continuously rotates to support the movement of the steel plate until the cut-to-length shear operation is completed.

[0054] Equipment maintenance and care

[0055] After the device has been used for a period of time, the wear of the roller 3 is regularly checked. Since the roller 3 is in direct contact with the steel plate, it is easy to wear. If the roller 3 is found to be seriously worn, the roller 3 can be easily removed from the box-type trough 2 by disassembling the first nut and the second nut and replaced with a new roller 3 to ensure the operating performance of the device and the stability of the steel plate conveying.

[0056] Check the gaskets for wear or damage, and replace them in time to ensure that the height of the roller 3 can be adjusted continuously and accurately. At the same time, clean the surface of the device regularly to remove iron filings, dust and other impurities left during the steel plate conveying process to ensure the normal operation of the device.

[0057] Check the connection between the box-type trough 2 and the guard plate 1, and the structural integrity of each component. If there is any looseness or damage, it should be repaired and tightened in time to maintain the stability of the overall structure of the device, so as to extend the service life of the device and ensure long-term stable and reliable operation.

[0058] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
