Description

Technical Field

[0001] The utility model relates to the field of rolling mill auxiliary equipment, in particular to a rolling mill deviation correction photoelectric detector. Background Art

[0002] In modern cold-rolled strip production lines, strip deviation often occurs due to various factors such as long production lines, installation accuracy of unit equipment, manufacturing accuracy of rollers and wear after use, fast strip running speed, and poor strip shape (such as edge waves, sickle bends, welding offsets, etc.). Strip deviation not only makes it impossible to roll the strip neatly, but also causes scratches on the strip surface, collision and folding of the strip edge, and even production accidents such as strip breakage and equipment damage. In order to improve strip quality, reduce costs, and meet the market demand for high-quality strips, the correction control system has become an indispensable equipment in the cold rolling production line.

[0003] However, the current rolling mill deviation correction detection device has certain defects in actual use. A photoelectric detector can be used to detect whether there is an offset, but it cannot provide protection during actual use. Long-term use can easily cause dust to accumulate on the surface, affecting the accuracy of subsequent detection and use. At the same time, it cannot be protected when not in use and is easily affected by moisture or dust, affecting its service life. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5 According to an embodiment of the utility model, a rolling mill correction photoelectric detector includes a frame 1, two sets of assembly plates 2 are arranged on the frame 1, and a conveying device 3 for conveniently conveying materials is arranged between the two assembly plates 2 (it can be a conveying roller, etc., which is a relatively mature technology and will not be described here). A control box 4 can be installed on the side wall of the bottom end of the frame 1 by bolts, which can facilitate the operation of the rolling mill, etc., wherein only a partial diagram of the rolling mill is shown, and it also has a production line of the rolling mill composed of rolling rollers, uncoilers and coilers, which is a relatively mature technology and will not be described here.

[0026] See also Figure 1-Figure 5In order to detect the material before processing and avoid deviation, two sets of mounting brackets 5 of mounting components are vertically welded on the frame 1, and a horizontal plate 6 is welded between the two mounting brackets 5. The bottom end of the middle part of the horizontal plate 6 is clamped with a mounting block 8 (the cross-section of which is U-shaped) of a clamping mechanism, and the mounting block 8 and the photoelectric detector body 9 can be fixed and installed by bolts, which is electrically connected to the control box 4 for easy detection. A corresponding correction device is also provided, which can perform correction operation when deviation occurs. It is a relatively mature technology and will not be described in detail here. In order to facilitate its installation and disassembly operations, it is convenient to install and disassemble it in case of failure or need to be replaced. When replacing, maintenance or replacement operations are carried out, positioning holes 10 of the positioning components are opened on the mounting block 8 and the cross plate 6, and a positioning column 12 is movably inserted inside the positioning column 12. A cylindrical pull plate 11 is welded to the end of the positioning column 12 (that is, located on the outer part), which can be conveniently pulled and pushed. In order to ensure that it will not slide and fall off after installation, a spring 13 is sleeved on the outside of the positioning column 12 (located between the pull plate 11 and the mounting block 8), which can be limited after being inserted into the positioning hole 10 to avoid detachment from the positioning hole 10. When disassembling, you only need to pull the pull plate 11 to pull the positioning column 12 out of the positioning hole 10 to complete the disassembly operation.

[0027] See also Figure 1-Figure 5 In order to protect the photoelectric detector body 9 when not in use, avoid dust accumulation and moisture, and ensure cleanliness during use, thereby ensuring the accuracy of detection, two groups of vertical plates 7 of protective mechanisms are symmetrically welded at the bottom end of the horizontal plate 6, and electric push rods 16 are installed on the side walls close to each other of the vertical plates 7. The output ends of the two groups of electric push rods 16 at the same end are jointly installed with a protective cover 21, which is provided with a card slot 19 adapted to the mounting block 8, and a wiping pad 18 (the material can be sponge, etc.) is bonded to the bottom end inside for wiping the photoelectric detector body 9. In order to ensure the stability of opening and closing movement, two groups of guide blocks 20 are welded on the top of the protective cover 21, and a guide groove 14 is provided at the bottom end of the horizontal plate 6 for facilitating the reciprocating sliding of the guide block 20. In order to ensure the protective effect, a sealing strip 17 of a sealing assembly is bonded to the side wall at the bottom end of one of the protective covers 21, and a sealing groove 15 is provided at the corresponding position of the other protective cover 21, and the two are plugged in and sealed.

[0028] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0029] The material can be transported by the conveying device 3, and the material before processing can be detected by the photoelectric detector body 9 to avoid the occurrence of deviation, and then the subsequent processing can be carried out to improve the processing quality. When it is not in use and needs to be protected, the electric push rod 16 is extended, and the protective cover 21 is brought close to each other, and the guide block 20 slides in the guide groove 14 to ensure the stability of movement, and then the sealing strip 17 enters the sealing groove 15 to complete the splicing, which can provide protection for the photoelectric detector body 9 to avoid dust accumulation or moisture, and provide protection for it to ensure service life and accuracy. When it is needed to be used, the electric push rod 16 is retracted, and the two protective covers 21 are opened away from each other. At the same time, the photoelectric detector body 9 can be wiped by the wiping pad 18 to ensure the cleanliness of the surface. When it needs to be disassembled for inspection or replacement, the pull plate 11 is pulled to move the positioning column 12 away from the positioning hole 10, and the spring 13 is stretched by force to store potential energy, and the positioning of the mounting block 8 is lost. The mounting block 8 and the photoelectric detector body 9 can be removed for easy inspection or replacement.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
