Technical Field
[0001] This utility model relates to the field of steel strip processing technology, and in particular to a steel strip guiding device. Background Technology
[0002] Steel strip processing is the process of producing narrow and long steel plates with specific properties and dimensions by processing steel through a series of processes. First, suitable steel is selected as raw material, usually low-carbon steel or alloy steel. Then, according to product requirements, hot rolling or cold rolling processes are selected. Hot rolling is carried out at high temperatures and is suitable for large-scale production, while cold rolling is carried out at room temperature, which can obtain higher surface finish and dimensional accuracy. Afterwards, heat treatment is carried out to improve mechanical properties, and surface treatments such as galvanizing and spraying are performed to improve corrosion resistance and aesthetics. Finally, it is cut into the corresponding length and width according to customer needs. During transportation, steel strips require the use of guiding devices.
[0003] However, the uniform spacing of the pressure rollers makes it difficult to flexibly adapt to steel strips of different thicknesses during the guiding and processing of steel strips, which severely limits the processing range. Frequent machine stops are required for manual adjustment or replacement of equipment parts, which greatly reduces processing efficiency, increases production costs, and is also prone to quality problems such as scratches and deformation on the surface of the steel strip due to improper adaptation, making it difficult to meet diverse production needs. Utility Model Content
[0004] The purpose of this utility model is to solve the problems in the existing technology where the uniform spacing of the pressure rollers makes it difficult to flexibly adapt to steel strips of different thicknesses during steel strip guiding and processing, which seriously limits the processing range, requires frequent machine stops for manual adjustment or replacement of equipment parts, greatly reduces processing efficiency, increases production costs, and is also prone to quality problems such as scratches and deformation on the surface of the steel strip due to improper adaptation, making it difficult to meet diverse production needs. Therefore, the proposed strip guiding device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a strip steel guide device, comprising a base and a spacing adjustment device, a frame fixedly connected to the upper surface of the base, a first pressure roller rotatably connected to the surface of the frame, a second pressure roller provided at one end of the frame near the first pressure roller, a first clamping roller installed on one side of the base, a crossbeam provided on the upper surface of the first clamping roller, a second clamping roller fixedly installed at one end of the crossbeam, the spacing adjustment device being disposed on the surface of the frame, the spacing adjustment device comprising a slider, the slider being slidably connected to the frame, two sliders being symmetrically arranged, the two ends of the second pressure roller being rotatably connected to the sliders respectively, a column fixedly connected to the surface of the frame, an insertion hole provided on the slider, the column being slidably connected to the insertion hole of the slider, an adjustment groove provided on the surface of the column, and a limiting mechanism for cooperating with the adjustment groove provided on the surface of the slider.
[0006] By setting up a spacing adjustment device, the spacing between the first and second pressure rollers can be easily adjusted, which can easily meet the processing needs of steel strips of different thicknesses, expand the applicability of the equipment, reduce the need to replace equipment or molds due to incompatibility with steel strips of different thicknesses, and reduce production costs.
[0007] Preferably, the limiting mechanism includes a connecting plate, a rod is rotatably connected to the surface of the connecting plate, a wheel is fixedly connected to the surface of the rod, a locking plate is fixedly connected to the surface of the wheel, a protrusion is fixed to the side of the locking plate near the column, and the protrusion on one side of the locking plate engages with the adjustment groove on the surface of the column.
[0008] Preferably, the surface of the wheel is provided with a through groove, and the surface of the rod is fitted with a torsion spring, with the two ends of the torsion spring being fixedly connected to the connecting plate and the through groove on the surface of the wheel, respectively.
[0009] Preferably, a cleaning component is provided on the upper surface of the frame. The cleaning component includes a hollow tube, which is fixedly connected to the upper surface of the frame. An air pump is fixedly connected to one end of the frame and is connected to the hollow tube. An air pipe is fixedly connected to the lower surface of the hollow tube and is connected to the hollow tube. The air pipe is located on the upper surface of the second pressure roller.
[0010] Preferably, there are multiple tracheas, which are arranged in a linear array along the hollow tube.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] In this invention, by setting a spacing adjustment device, the steel strip is clamped between the first and second pressure rollers during the guiding process. The rotation of the first and second pressure rollers drives the steel strip to move and transport. At the same time, the first and second clamping rollers hold the steel strip, reducing the displacement of the steel strip position. When processing steel strips of other thicknesses is required, the pressing wheel moves the clamping plate away from the column, and then the slider can be pulled to move along the column. When the slider drives the spacing between the second and first pressure rollers to the appropriate position, the wheel is released, and the torsion spring loses its restraint and generates elastic force to squeeze the clamping plate, causing the protrusion to insert into the adjustment groove of the column to complete the fixing adjustment. By setting a spacing adjustment device, the spacing between the first and second pressure rollers can be easily adjusted, which can easily meet the processing needs of steel strips of different thicknesses, expand the applicability of the equipment, reduce the need to change equipment or molds due to incompatibility with steel strips of different thicknesses, and reduce production costs.
[0013] In this invention, by setting up a cleaning component, when the first and second pressure rollers guide the steel strip, impurities adhere to the pressure rollers. As the pressure rollers rotate, these impurities squeeze the steel strip, easily causing scratches. At this time, the air pump is activated, driving airflow into the hollow tube and out through the air pipe. The air pipe guides the airflow to the second pressure roller, blowing off the impurities. By setting up the cleaning component, impurities adhering to the first and second pressure rollers can be removed in time during the steel strip guiding process, preventing impurities from squeezing the steel strip and causing scratches. This effectively ensures the integrity and smoothness of the steel strip surface, improves product quality, and reduces the product scrap rate caused by surface defects. Attached Figure Description

[0020] Please see Figures 1-5 This utility model provides a technical solution: a strip steel guiding device, including a base 1 and a spacing adjustment device 8. A frame 2 is fixedly connected to the upper surface of the base 1, a first pressure roller 3 is rotatably connected to the surface of the frame 2, a second pressure roller 7 is provided at one end of the frame 2 near the first pressure roller 3, a first clamping roller 4 is installed on one side of the base 1, a crossbeam 5 is provided on the upper surface of the first clamping roller 4, a second clamping roller 6 is fixedly installed at one end of the crossbeam 5, and the spacing adjustment device 8 is provided on the surface of the frame 2.
[0021] In this embodiment: the spacing adjustment device 8 includes a slider 81, which is slidably connected to the frame 2. There are two sliders 81, which are symmetrically arranged. The two ends of the second pressure roller 7 are rotatably connected to the sliders 81 respectively. A column 82 is fixedly connected to the surface of the frame 2. A vertical insertion hole is opened on the slider 81. The column 82 is vertically inserted into the insertion hole and slidably connected to the insertion hole of the slider 81. An adjustment groove is opened on the surface of the column 82. A connecting plate 83 is fixedly connected to the surface of the slider 81. By setting the spacing adjustment device 8, the spacing between the first pressure roller 3 and the second pressure roller 7 can be easily adjusted, which can easily meet the processing needs of steel strips of different thicknesses, expand the application range of the equipment, reduce the situation that equipment or molds need to be replaced due to incompatibility with steel strips of different thicknesses, and reduce production costs.
[0022] Specifically, a rod 84 is rotatably connected to the surface of the connecting plate 83, a wheel 86 is fixedly connected to the surface of the rod 84, and a clamping plate 85 is fixedly connected to the surface of the wheel 86. By setting the wheel 86, when it is necessary to process steel strips of different thicknesses and adjust the spacing, rotating the wheel 86 can drive the clamping plate 85 to overcome the elastic force of the torsion spring 87 and move it away from the column 82. This releases the limiting constraint on the slider 81, thereby enabling the slider 81 to move along the column 82.
[0023] Specifically, a protrusion is fixed on the side of the clamping plate 85 near the column 82. The protrusion on one side of the clamping plate 85 engages with the adjustment groove on the surface of the column 82. By setting the clamping plate 85, the slider 81 can move along the column 82 to adjust the distance between the first pressure roller 3 and the second pressure roller 7. The clamping plate 85, through the protrusion on it, is inserted into the adjustment groove of the column 82, which can restrict the movement of the slider 81, thereby fixing the position of the slider 81 on the column 82, ensuring that the adjusted distance between the first pressure roller 3 and the second pressure roller 7 remains stable, so that the distance between the pressure rollers will not change when the equipment processes the steel strip, thus ensuring the stability and accuracy of the processing.
[0024] Specifically, the surface of the wheel 86 is provided with a through groove, and the surface of the rod 84 is fitted with a torsion spring 87. The two ends of the torsion spring 87 are fixedly connected to the connecting plate 83 and the through groove on the surface of the wheel 86, respectively. By setting the torsion spring 87, when the wheel 86 is rotated and the locking plate 85 is moved away from the column 82, the torsion spring 87 is compressed or twisted to accumulate elastic potential energy. Once the wheel 86 is released, the torsion spring 87 immediately releases the previously accumulated elastic potential energy, generating an elastic force to squeeze the locking plate 85, causing the locking plate 85 to drive the protrusion to re-insert into the adjustment groove of the column 82, thereby locking the position of the slider 81. The connecting plate 83, the rod 84, the locking plate 85, the wheel 86 and the torsion spring 87 constitute a limiting mechanism.
[0025] Specifically, a cleaning component 88 is provided on the upper surface of the frame 2. The cleaning component 88 includes a hollow tube 881, which is fixedly connected to the upper surface of the frame 2. An air pump 883 is fixedly connected to one end of the frame 2, and the air pump 883 is connected to the hollow tube 881.
[0026] In this embodiment: by setting up a cleaning component 88, impurities adhering to the pressure roller are effectively removed. Since impurities may squeeze the steel strip and cause it to scratch when the pressure roller rotates, the cleaning component 88 uses an air pump 883 to allow airflow into the hollow tube 881 and guides it to the second pressure roller 7 through the air pipe 882. The airflow blows off the impurities, thereby avoiding quality problems such as scratches on the steel strip caused by impurities and ensuring the surface quality of the steel strip during the processing.
[0027] Specifically, an air pipe 882 is fixedly connected to the lower surface of the hollow tube 881, and the air pipe 882 is located on the upper surface of the second pressure roller 7.
[0028] In this embodiment: by setting up an air pipe 882, the air pipe 882 can guide the airflow generated by the air pump 883 to the second pressure roller 7 in a targeted manner, so that the airflow can accurately act on the position that needs to be cleaned, that is, the impurities adhering to the second pressure roller 7, ensuring that the cleaning airflow can play an effective role and improving the accuracy and efficiency of cleaning.
[0029] Specifically, there are multiple tracheas 882, which are arranged in a linear array along the hollow tube 881, and the tracheas 882 are connected to the hollow tube 881.
[0030] Working principle: By setting the spacing adjustment device 8, when guiding the steel strip, the steel strip is clamped between the first pressure roller 3 and the second pressure roller 7. The rotation of the first pressure roller 3 and the second pressure roller 7 drives the steel strip to move and transport. At the same time, the first clamping roller 4 and the second clamping roller 6 clamp the steel strip to reduce the displacement of the steel strip position. When processing steel strips of other thicknesses is required, the rotating wheel 86 drives the clamping plate 85 away from the column 82. Then, the slider 81 can be pulled to move along the column 82. When the slider 81 drives the spacing between the second pressure roller 7 and the first pressure roller 3 to the appropriate position, the rotating wheel 86 is released. The torsion spring 87 loses its restraint and generates elastic force to squeeze the clamping plate 85, which drives the protrusion to insert into the adjustment groove of the column 82 to complete the fixation adjustment. By setting the spacing adjustment device 8, the spacing between the first pressure roller 3 and the second pressure roller 7 can be easily adjusted, which can easily meet the processing needs of steel strips of different thicknesses, expand the application range of the equipment, reduce the situation that equipment or molds need to be replaced due to incompatibility with steel strips of different thicknesses, and reduce production costs.
[0031] By setting up the cleaning component 88, when the first pressure roller 3 and the second pressure roller 7 guide the steel strip, impurities adhere to the pressure rollers. When the pressure rollers rotate, they cause the impurities to squeeze the steel strip, which can easily lead to scratches on the steel strip. At this time, the air pump 883 is activated. The air pump 883 drives the airflow into the hollow tube 881 and discharges it through the air pipe 882. The air pipe 882 guides the airflow to the second pressure roller 7 and blows off the impurities. By setting up the cleaning component 88, impurities adhering to the first pressure roller 3 and the second pressure roller 7 can be removed in time during the steel strip guiding process, preventing impurities from squeezing the steel strip and causing scratches. This effectively ensures the integrity and smoothness of the steel strip surface, improves product quality, and reduces the product scrap rate caused by surface defects.
