Description

Technical Field

[0001] This utility model relates to the technical field of monocrystalline silicon cleaning equipment, specifically to a roller brush adjustment mechanism for an edge material cleaning machine. Background Technology

[0002] Edge scrap refers to the waste material cut from the edges of monocrystalline silicon round rods. This material is considered high-quality in photovoltaic monocrystalline silicon production, with high silicon purity, suitable for use in crystal pulling. Larger wafers need to be ground first to remove the surface coating before subsequent raw material processing. Before processing the edge scrap, it needs to be cleaned and bonded together with a specific adhesive to form a continuous, whole piece of edge scrap. Then, it is cut using diamond wire cutting equipment. The resulting edge scrap is sent for debonding.

[0003] The cleaning of edge leather is generally carried out using a cleaning machine. Existing cleaning machines are divided into two types: immersion cleaning and spray-type roller brush cleaning. Spray-type roller brush cleaning mainly relies on the bristles on the roller brush surface to physically rub the edge leather surface while simultaneously spraying cleaning agent. With prolonged use, the roller brush bristles experience normal wear and tear, gradually shortening and reducing their ability to press firmly against the edge leather surface. This significantly reduces the cleaning effect of physical friction. Furthermore, the remaining bristles have a certain length that cannot be fully utilized. The large number of roller brushes in each cleaning machine and the high frequency of brush replacement lead to increased costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a roller brush adjustment mechanism for a leather cleaning machine. This mechanism allows for the up-and-down adjustment of the roller brush, ensuring that the brush bristles always contact the surface of the leather and guaranteeing the cleaning effect of physical friction.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0022] like Figure 1-4As shown, a roller brush adjustment mechanism for a scrap material washing machine is disclosed. This mechanism is mainly used to adjust the roller brushes, which are installed inside an outer housing 1. A back plate 4 is vertically fixed inside the outer housing 1. The back plate 4 divides the internal space of the outer housing 1 into front and rear parts. The front part is the scrap material conveying space, and the rear part is the operating space for the adjustment mechanism. One or more upper roller brushes 2 and lower roller brushes 3 are arranged alternately in the front part of the outer housing 1. A gap is reserved between the upper roller brushes 2 and the lower roller brushes 3 for the scrap material to pass through, and the scrap material moves along the conveying roller 15. Movable grooves 4.1 are opened on the surface of the back plate 4 corresponding to the upper roller brushes 2 and the lower roller brushes 3. The shafts of the upper roller brushes 2 and the lower roller brushes 3 pass through the movable grooves 4.1 and are connected to the drive ends of their respective upper roller drive motors 7 and lower roller drive motors 8. Movable baffles 14 are provided on the shafts of the upper roller brushes 2 and the lower roller brushes 3 corresponding to the movable grooves 4.1. The movable baffles 14 move up and down along the movable grooves 4.1 to block and cover the movable grooves 4.1. The upper roller drive motor 7 and the lower roller drive motor 8 are located behind the back plate 4 and are isolated from the spraying area. There are three upper roller brushes 2 as a group and two lower roller brushes 3 as a group. Each group of upper roller brushes 2 and each group of lower roller brushes 3 constitutes a cleaning unit. Multiple cleanings ensure the cleaning effect.

[0023] like Figure 1-3 As shown, an upper adjusting frame 5 and a lower adjusting frame 6 are provided in the rear space of the outer casing 1; an upper roller drive motor 7 is fixed to the surface of the upper adjusting frame 5; the top center of the upper adjusting frame 5 is movably connected to the bottom of the upper adjusting screw 9; a first threaded hole 1.1 is provided at the position of the upper adjusting screw 9 corresponding to the position of the outer casing 1; the upper adjusting screw 9 drives the upper adjusting frame 5 to move up and down along the first threaded hole 1.1; a first guide rod 17 is vertically fixed at the top of the upper adjusting frame 5; a first guide sleeve 19 is provided at the position of the first guide rod 17 at the top of the outer casing 1; the first guide rod 17 moves up and down along the first guide sleeve 19. The first guide rod 17 ensures the stability of the upper adjusting frame 5 during the lifting process.

[0024] like Figure 1-3 As shown, the lower roller drive motor 8 is fixed to the surface of the lower adjusting frame 6; a support plate 11 is fixed to the back of the back plate 4; the support plate 11 is located above the lower adjusting frame 6; the middle of the surface of the lower adjusting frame 6 is movably connected to the bottom of the lower adjusting screw 10; a second threaded hole 11.1 is provided at the position of the support plate 11 corresponding to the lower adjusting screw 10; the lower adjusting screw 10 drives the lower adjusting frame 6 to move up and down along the second threaded hole 11.1. A second guide rod 18 is vertically fixed to the top of the lower adjusting frame 6; a second guide sleeve 20 is provided on the surface of the support plate 11 corresponding to the position of the second guide rod 18; the second guide rod 18 moves up and down along the second guide sleeve 20. The second guide rod 18 ensures the stability of the support plate 11 during the lifting process. A manually adjustable turntable 16 is fixed to the top of the upper adjusting screw 9 and the lower adjusting screw 10 for easy manual adjustment.

[0025] Furthermore, to control the height adjustment value, a pointer 12 is fixed to the top of the first guide rod 17 and the second guide rod 18, and a scale 13 corresponding to the pointer 12 is provided on one side of the pointer 12; the scale 13 of the first guide rod 17 is fixed to the outer casing 1; the scale 13 of the second guide rod 18 is fixed to the support plate 11. Unless otherwise described, the fixing method is achieved by welding or threading using common techniques employed by industry professionals.

[0026] The working principle is as follows:

[0027] Before the initial operation of the equipment, the spacing between the upper roller brush 2 and the lower roller brush 3 should be adjusted. During the movement of the edge material, the upper roller brush 2 and the lower roller brush 3 can respectively brush the surface and bottom of the edge material. After a certain period of use, the maintenance personnel need to check regularly to confirm the wear degree of the upper roller brush 2 and the lower roller brush 3 inside the equipment. Adjust the upper adjusting screw 9 and the lower adjusting screw 10 according to the wear degree to ensure that the brushes are always in contact with the edge material. According to the scale indication, once the pointer 12 reaches the specified minimum scale position, it means that the brush bristles of the upper roller brush 2 and the lower roller brush 3 are worn out and can no longer meet the usage requirements, and need to be replaced.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
