Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically to a device for double-sided cleaning of thin metal sheets. Background Technology

[0002] Before deep drawing thin sheets of iron, aluminum, or other metals, patterns, varnishes, or other coatings are often printed on the sheet surface. During this process, moisture, oil, dust, or other contaminants frequently adhere to both surfaces of the sheet. If the sheet is not cleaned before being fed into the press, these surface deposits will not only reduce the lifespan of the stamping die during deep drawing, but some contaminants will also remain on the surface of the finished workpiece, affecting its quality and, in severe cases, even causing the stamping die or the finished part to be scrapped. Existing metal sheet cleaning devices generally suffer from low cleaning efficiency and poor cleaning effect; therefore, there is a need to develop a device for double-sided cleaning of metal sheets. Utility Model Content

When the friction disc rotates, it drives the feeding roll cloth to rotate together through the second rotating shaft.

[0018] The working principle of this utility model is as follows:

[0019] A single sheet of metal, divided into rectangles or squares, is placed at the initial position of the pusher. The piston rod of the double-acting cylinder with guide rod retracts, and the soft cleaning brush is in a high position. The upper roll cleaning cloth is released from the upper feed wheel assembly, passes through the idler wheels on the upper and lower idler wheel assemblies, and is then positioned by the upper and lower rollers on the positioning assembly on the right side of the cleaning assembly. It is then guided by the upper guide plate to the top of the upper guide plate. The lower roll cleaning cloth is released by the lower feed wheel assembly and pressed onto the upper surface of the soft cleaning brush by the lower guide plate. There is a certain gap between the upper and lower roll cleaning cloths. The front edge of the metal sheet enters between the upper and lower roll cleaning cloths through the gap between the upper and lower guide plates. The rear edge of the metal sheet is pushed forward by the pusher, and the sheet continues to move forward. When the front edge of the metal sheet has not passed through the width of the roll cleaning cloth, the piston rod of the double-acting cylinder with guide rod is in a retracted state, ensuring that the front edge of the metal sheet passes smoothly through the gap between the upper and lower roll cleaning cloths, so that there is no jamming during the process.

[0020] As the leading edge of the metal plate passes the right edge of the upper and lower roller cleaning cloths, the piston rod of the double-acting cylinder with guide rod immediately extends, and the soft cleaning brush is in a low position. The lower surface of the soft cleaning brush presses the upper roller cleaning cloth onto the upper surface of the metal plate. Under the pressing action of the soft cleaning brush, the lower surface of the metal plate is tightly pressed against the lower roller cleaning cloth.

[0021] The metal sheet is pushed forward by the pusher block. After the front edge of the metal sheet is pushed into the press feed roller, the feed roller sends the metal sheet into the press feeding system. During this process, the piston rod of the double-acting cylinder 53 with guide rod is always extended. Under the pressing action of the soft cleaning brush, the upper and lower roller cleaning cloths clean the upper and lower surfaces of the metal sheet respectively, achieving double-sided cleaning of the sheet. The cleaning effect can be adjusted by adjusting the pressure of the roller cloth.

[0022] After a sheet of material is completely cleaned by passing through the upper and lower cleaning cloths, the piston rod of the double-acting cylinder with guide rod retracts, and the soft cleaning brush returns to its high position, ready for the next work cycle.

[0023] After cleaning a certain quantity of sheet metal, the cleaning cloth on the roll in the cleaning work area becomes contaminated and is no longer suitable for further cleaning. At this point, the contaminated cleaning cloth is guided by the upper and lower guide plates to the upper and lower rollers on the positioning assembly on the left side of the cleaning component for positioning. After passing through the idler wheel assembly, it is finally driven by the servo reduction motor in the take-up roller assembly to rotate, winding a length of contaminated cloth equal to the width of the sheet metal onto the take-up roller. Simultaneously, a clean cleaning cloth of the same length is released from the unloading roller assembly, initiating the subsequent cleaning process. Compared with existing technologies, the beneficial effects of this invention include:

[0024] 1. This utility model device uses a roll cleaning cloth as the cleaning medium, which can complete the cleaning work without affecting the normal production of the punch press. The cleaning does not occupy production time and ensures the production efficiency of the entire line.

[0025] 2. This utility model device can effectively clean both sides of the board material at the same time. The cleaning effect on both sides of the board material can be adjusted by adjusting the pressure of the cleaning cloth on the roller. It has high cleaning efficiency and good cleaning effect.

[0054] See Figure 9-10 The working principle of this utility model is as follows:

[0055] A single sheet of metal, divided into rectangles or squares, is placed at the initial position of the pusher. The piston rod of the double-acting cylinder 53 with guide rod retracts, and the soft cleaning brush 50 is in a high position. The upper roll cleaning cloth is released from the upper feed wheel assembly, passes through the idler wheels 30 on the upper and lower idler wheel assemblies, and is then positioned by the upper roller 45 and lower roller 44 on the positioning assembly 4 on the right side of the cleaning assembly. It is then guided by the upper guide plate 7 to the top of the upper guide plate 7. The lower roll cleaning cloth is released from the lower feed wheel assembly and pressed onto the upper surface of the soft cleaning brush 62 by the lower guide plate 61. There is a certain gap between the upper and lower roll cleaning cloths. The front edge of the metal sheet enters between the upper and lower roll cleaning cloths through the gap between the upper guide plate 7 and the lower guide plate 61. The rear edge of the metal sheet is pushed forward by the pusher, and the sheet continues to move forward. When the front edge of the metal plate does not pass through the width of the cleaning cloth on the roller, the piston rod of the double-acting cylinder 53 with guide rod is in the retracted state, ensuring that the front edge of the metal plate passes smoothly through the gap between the upper and lower cleaning cloths, so that there is no jamming during the passage.

[0056] As the leading edge of the metal plate passes the right edge of the upper and lower roller cleaning cloths, the piston rod of the double-acting cylinder 53 with guide rod immediately extends, and the soft cleaning brush 50 is in a low position. The lower surface of the soft cleaning brush 50 presses the upper roller cleaning cloth onto the upper surface of the metal plate. Under the pressing action of the soft cleaning brush 50, the lower surface of the metal plate is tightly attached to the lower roller cleaning cloth.

[0057] The metal sheet is pushed forward by the pusher block. After the front edge of the metal sheet is pushed into the press feed roller, the feed roller sends the metal sheet into the press feeding system. During this process, the piston rod of the double-acting cylinder 53 with guide rod is always extended. Under the pressing action of the soft cleaning brush 50, the upper and lower roller cleaning cloths clean the upper and lower surfaces of the metal sheet respectively, achieving double-sided cleaning of the sheet. The cleaning effect can be adjusted by adjusting the pressure of the roller cloth.

[0058] After a sheet of material has been completely cleaned by passing through the upper and lower rollers of the cleaning cloth, the piston rod of the double-acting cylinder 53 with guide rod retracts, and the soft cleaning brush 50 returns to its high position, ready for the next work cycle.

[0059] After cleaning a certain number of sheets, the cleaning cloth on the roll in the cleaning work area becomes contaminated and is no longer suitable for cleaning. At this time, the contaminated cleaning cloth is guided by the upper guide plate 7 and the lower guide plate 61 to the upper roller 45 and the lower roller 44 on the positioning component 4 on the left side of the cleaning component for positioning. After passing through the idler wheel assembly 3, the servo reduction motor 26 in the take-up roller assembly 2 drives the take-up roll cloth 21 to rotate, winding the contaminated roll cloth with a length equal to the width of the metal sheet onto the take-up roll 21. At the same time, a clean roll cloth of the same length is released from the unloading roller assembly 8, and the subsequent cleaning action begins.
