Description

Technical Field

[0001] This utility model relates to the field of roller press technology, and in particular to a laser cleaning device for cleaning the surface of roller press rolls. Background Technology

[0002] In the battery electrode manufacturing process, after the electrode is coated and dried, it needs to be rolled by a roller press to increase the bonding strength between the coating material and the electrode.

[0003] During the rolling process, a lot of impurities and dirt will adhere to the surface of the rollers of the roller press. These small impurities left over from the electrode coating will affect the rolling effect. Therefore, it is necessary to clean the roller surface in time to ensure that the roller surface remains clean.

[0004] The cleaning mechanisms of existing roller presses typically use non-woven fabric to wipe the surface of the rollers to remove impurities. However, the mechanical structure used is relatively complex. During the wiping process, the linear speed of the roller corresponding to the non-woven fabric is between 50-60 m / min. Once the linear speed of the roller exceeds the above range, the cleaning effect will be greatly affected, and it may even fail to clean properly. The width of the non-woven fabric must also be changed accordingly for rollers of different widths. Moreover, the non-woven fabric is consumed quickly, increasing the workload of replacement and maintenance. Utility Model Content

[0007] Specifically, the slide rod is provided with a bearing seat at both ends, and the two ends of the slide rod are fixed to their respective bearing seats.

[0008] Furthermore, to facilitate the adjustment of the laser position, a mounting plate is vertically fixed to the front side of the connecting plate. An elongated hole is provided on the upper part of the mounting plate, through which the laser can be adjusted and fixed on the mounting plate.

[0009] Furthermore, a first connecting plate is fixed to the bottom right side of the connecting plate, and a second connecting plate is fixed to the rear side of the connecting plate. The dust collection box is fixed to the connecting plate through the first and second connecting plates.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figure 1 , Figure 2The roller laser cleaning device shown is used to install the roller 1 on the left side of the roller press. It includes two fixed seats 2 spaced apart. The fixed seats 2 can be fixed on the frame of the roller press. A lead screw module 3 as the driving force is installed between the two fixed seats 2. A drag chain bracket 15 is fixed on the bottom left side of the lead screw module 3. A drag chain 16 that provides power to the lead screw module 3 is provided on the drag chain bracket 15.

[0019] A bearing seat 9 is provided at both ends of the right side of the lead screw module 3. A slide rod 4 is installed between the bearing seats 9. A rectangular connecting plate 5 is fixed on the slide of the lead screw module 3. A linear bearing 6 that slides with the slide rod 4 is provided on the bottom surface of the connecting plate 5. The lead screw module 3 drives the connecting plate 5 to move along the axial direction of the roll 1 on the slide rod 4.

[0020] A mounting plate 10 is vertically fixed to the front right side of the connecting plate 5. A laser 7 with the laser head facing the outer periphery of the roll 1 is mounted on the mounting plate 10. In order to facilitate the adjustment of the angle of the laser 7, an elongated hole 10-1 is opened on the upper part of the mounting plate 10. In this way, the laser 7 can be adjusted and fixed on the mounting plate 10 through the elongated hole 10-1.

[0021] A dust collection box 8 is provided between the laser head of the laser 7 and the outer peripheral surface of the roller 1. The specific installation structure of the dust collection box 8 is as follows: a first connecting plate 11 is fixed on the bottom right side of the connecting plate 5, and a second connecting plate 12 is fixed on the rear side of the connecting plate 5. The dust collection box 8 is fixed to the connecting plate 5 through the first connecting plate 11 and the second connecting plate 12.

[0022] A dustproof plate 13 is installed at the inlet of the dust collection box 8. The dustproof plate 13 has a through hole 13-1 for the laser head of the laser 7 to pass through and get close to the outer circumference of the roller 1. The dustproof plate 13 has elongated holes 13-2 on both sides to facilitate the vertical adjustment of the height of the dustproof plate 13. The installation height of the dustproof plate 13 is adjusted by the elongated holes 13-2 so that the laser head of the laser 7 matches the position of the through hole 13-1. The outlet of the dust collection box 8 is connected to a negative pressure pipe 14 so as to suck the impurities and dust collected by the dust collection box 8 into the waste bin.

[0023] In use, the lead screw module 3 drives the connecting plate 5 to move back and forth along the axis of the roll 1. After adjusting the position of the laser 7, the laser head of the laser 7 sprays pulsed light onto the outer circumferential surface of the roll 1. The dust and impurities on the outer circumferential surface of the roll 1 will instantly vaporize and accumulate in the dust collection box 8, and be sucked out from the negative pressure pipe 14.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
