Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water squeezing equipment, and more specifically to a grinding brush water squeezing device. Background Art
[0002] In the process of producing lithium battery copper foil by electrolysis, the cathode roller is the key equipment. On the cathode roller, copper ions are reduced to obtain copper foil. During the production process, the cathode roller is not only corroded by the copper sulfate solution, but also by the friction when the copper foil is peeled off. The state of the cathode roller surface (surface grain size, geometry, flatness, roughness) will change accordingly. When the surface state deteriorates to a certain extent, it will affect the quality of the copper foil. If the surface roughness of the cathode roller increases, the current density on the cathode roller surface will decrease, and the electrode potential will not reach the precipitation potential of copper, resulting in defects such as difficulty in copper precipitation and uneven copper grain size. Therefore, it is necessary to polish the cathode roller regularly.
[0003] Cathode roller polishing is divided into two steps: wet polishing and dry polishing. Wet polishing is to replenish water while polishing, so that the brush is always in a hydrated state to polish the cathode roller; dry polishing is to squeeze out the water from the brush after wet polishing and then polish. At present, in the dry polishing process, water is squeezed out of the brush by pressing a water pipe on the brush with both hands, so that the brush rotates quickly to achieve the effect of squeezing out water. There is a high safety risk. The water pipe is easy to slip out of the hand and cause the hand to be scratched by the brush. Therefore, a water squeezing device is designed to replace the hand squeezing water with the water pipe. The device uses the principle of leverage to press the stainless steel pipe on the rotating brush to squeeze and absorb the brush. Utility Model Content

[0016] 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.
[0017] refer to Figure 1 A brush squeezing device comprises a base 1, a bracket 2 is rotatably connected to the base 1, so that the bracket 2 swings with the base 1 as the center, a squeezing pipe 3 is installed on one side of the swinging direction of the bracket 2, and a plurality of suction holes 4 arranged at intervals are opened on the side of the squeezing pipe 3 away from the bracket 2, and a water suction pipe 5 is also connected to the squeezing pipe 3. When in use, the brush stops rotating, the utility model is fixed to one side of the brush, a vacuum cleaner is connected to the water suction pipe 5, the brush is rotated, the vacuum cleaner is turned on, the bracket 2 is pushed so that the outer wall of the squeezing pipe 3 and the suction hole 4 are against the outer wall of the brush, and the water on the brush is squeezed dry; at the same time, the vacuum cleaner can suck out impurities on the brush.
[0018] In some embodiments, the rotational connection between the base 1 and the bracket 2 can be: the base 1 includes a U-shaped groove 11, at least two bearings 12 are installed in the U-shaped groove 11, a rotating shaft 13 is rotatably installed in the two bearings 12, and the bracket 2 is installed on the rotating shaft 13. It can be understood that the U-shaped groove plays a fixing role for the bearing 12. Of course, the bearing 12 can also be fixed by other structures, for example: a sleeve ring structure is used to be fixed on the outer ring of the bearing 12, and then the sleeve ring is fixed. When the bracket 2 swings, it swings around the rotating shaft 13. Further, in order to save more effort and materials, the bracket 2 is set vertically to the rotating shaft 13.
[0019] In some embodiments, the water squeezing tube 3 is perpendicular to the bracket 2, and its axial direction is parallel to the axial direction of the rotating shaft 13. It is understandable that during use, the outer wall of the water squeezing tube 3 needs to be completely against the brush surface, so the axial direction of the water squeezing tube 3 needs to be parallel to the axial direction of the brush. When fixing the base 1, the rotating shaft 13 is placed parallel to the brush. Since the water squeezing tube 3 is parallel to the rotating shaft 13, when the bracket 2 is pushed again, the outer wall of the water squeezing tube 3 can be completely against the brush. Furthermore, a propulsion handle 6 is installed at one end of the bracket 2 away from the base 1. The propulsion handle 6 can adopt a tubular structure, and its axial direction is also set to be parallel to the axial direction of the rotating shaft 13.
[0020] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
