Problems solved by technology
[0002] The spray cavity beam of paper machine coating is often caused by the entry of foreign matter, which causes the upper lip to be squeezed and deformed at a position about 100mm wide at the end surface of the transmission side, and the deformation is usually 2-3mm, resulting in the sprayed coating being unable to be evenly sprayed to the roller surface, seriously affecting the quality of paper coating
[0003] Since the length of the upper lip plate of the spray chamber beam reaches 8260mm, it is currently impossible to find grinding equipment with the same size on the market, and sending the equipment abroad for maintenance will not only cost a lot of maintenance, but also lengthen the maintenance cycle, and the maintenance effect cannot be guaranteed

Embodiment Construction
[0016] Due to the entry of foreign matter into the spray chamber beam of the paper machine coating, the upper lip is squeezed and deformed at a position of about 100mm wide at the end surface of the transmission side, usually the deformation is 2-3mm, resulting in the sprayed coating being unable to be evenly sprayed to the roller. On the surface, the quality of paper coating is seriously affected, and the correction device disclosed in the embodiment of the present invention can be used to repair the local deformation of the coating nozzle beam of any paper machine. see Figure 1-2 , figure 1 is a schematic structural view of a calibration device according to an embodiment of the present invention, figure 2 yes figure 1 An enlarged schematic of part A is shown. Such as Figure 1-2 As shown, the correction device 1 includes a jig 2 and a jack 3, the jig 2 includes a first part 21 and a second part 22 arranged on the first part 21, wherein the first part 21 and the second ...

The invention discloses a correcting device and a correcting method thereof. The correcting device comprises a clamp and a jack, the clamp comprises a first component and a second component arranged on the first component, the first component and second component form a space used for holding an upper lip plate to be corrected, the upper lip plate is arranged on the first component, after heating the lip of the upper lip plate, the second component is arranged on the upper lip plate, and the jack is arranged on the second component to pressurize the clamp to correct the upper lip plate. By means of the mode, the deformation position of the upper lip plate can be corrected through small grinding equipment, the demands on maintenance equipment and site are low, the maintenance cost is lowered, the maintenance time is shortened, and the coating for the upper lip plate of a spray chamber beam can realize uniform coating.
Description
technical field [0001] The present invention relates to the technical field of calibration devices, in particular to a calibration device and a calibration method thereof. Background technique [0002] The spray cavity beam of paper machine coating is often caused by the entry of foreign matter, which causes the upper lip to be squeezed and deformed at a position about 100mm wide at the end surface of the transmission side, and the deformation is usually 2-3mm, resulting in the sprayed coating being unable to be evenly sprayed to the roller surface, seriously affecting the paper coating quality. [0003] Since the length of the upper lip of the coating spray chamber beam reaches 8260mm, it is currently impossible to find grinding equipment with the same size on the market, and sending the equipment abroad for maintenance will not only cost a lot of maintenance, but also take a long maintenance period, and the maintenance effect cannot be guaranteed.
