[0027] Example 1
[0028] like Figure 1-4 As shown, a wire guide frame cleaning and anti-abrasion device includes a support 1, a water tank 2, a cleaning basket 3, a swing hinge frame 4, and a swing mechanism 5. The support 1 has a water tank 2 on its top surface, and the cleaning basket 3 is movably connected to the water tank 2. The bottom of the cleaning basket 3 has multiple drainage holes 32. The swing hinge frame 4 is located inside the cleaning basket 3 and is used to place vertically arranged wire guide frames at intervals. The swing mechanism 5 includes two swing components located on the top surface of the support 1. The two swing components are located on both sides of the water tank 2 and are diagonally arranged. The two swing components can drive the swing hinge frame 4 to swing alternately towards each other.
[0029] Among them, such as Figure 2-4 As shown, the inner side of the swing hinge frame 4 is provided with multiple sets of evenly arranged inserts 41, and a wire frame is inserted into each set of inserts 41. By using multiple sets of inserts 41, the wire frames are arranged vertically at intervals, which prevents the wire frames from abrading each other and facilitates cleaning and removal of debris from the surface of the wire frames.
[0030] like Figure 2-4 As shown, the swing hinge frame includes a drive vertical plate 42, a connecting vertical plate 43, and a connecting rod 44. There are two drive vertical plates 42, which are arranged one-to-one with the swing assembly. There are multiple connecting vertical plates 43, which are evenly arranged in a direction away from the drive vertical plate 42. The drive vertical plate 42 and the adjacent connecting vertical plate 43, as well as the adjacent connecting vertical plates 43, are hinged by the connecting rod 44. The drive vertical plate 42 and the connecting vertical plate 43 near the side wall of the washing basket 3 are both provided with a sliding post 45 in the middle. The side wall of the washing basket 3 is provided with a sliding plate 46 corresponding to the sliding post 45. The sliding plate 46 is provided with a sliding groove, and the sliding post 45 is inserted into the sliding groove and slidably connected to the sliding groove. In addition, the front and rear sides of the cleaning basket 3 are provided with slots 33 corresponding to the drive vertical plate 42 or the connecting vertical plate 43. The lower ends of the drive vertical plate 42 and the connecting vertical plate 43 are inserted into the slots 33. The width of the slots 33 is greater than the width of the drive vertical plate 42 and the connecting vertical plate 43. The swaying angle of the swing hinge frame 4 is limited by the slots 33.

The support cylinder 47 abuts against the bottom surface of the cleaning basket 3. The middle part of the swing hinge frame 4 is supported by the support cylinder 47, which provides better stability.
[0031] In addition, such as Figure 1-4As shown, the rocking assembly includes a mounting base 51, a cylinder 52, a toggle fixing block 53, and a push block 54. The mounting base 51 is fixed on the top surface of the bracket 1. The cylinder 52 is located on the top surface of the mounting base 51, and its output end is provided with the toggle fixing block 53. The upper end of the push block 54 is connected to the toggle fixing block 53, and the lower end is provided with a push guide wheel 55. During operation, cylinder 51 of one of the swing components activates to drive the guide wheel 55 to move. The guide wheel 55 pushes the drive part at the top of the drive vertical plate 42 to move, thereby causing the drive vertical plate 42 to rotate around the sliding column 45. The sliding column 45 slides synchronously in the sliding groove of the slide plate 46, thereby driving the connecting vertical plate 43, which is hinged by the connecting rod 44, to swing synchronously. Each set of insert blocks 41 of the wire guide frame is set on the vertical plates (drive vertical plate 42 or connecting vertical plate 43) arranged in opposite directions, and swings synchronously. Then, cylinder 51 of this swing component resets, and the other swing component is activated to drive the swing hinge frame 4 to swing in the opposite direction, realizing alternating opposite swings, which can improve the cleaning effect, ensure thorough cleaning, and reduce costs and increase efficiency for the company.
