A slitting machine is a device for longitudinal cutting of wide roll materials. So this word is used in various industries, and we can understand it from its scope of use. So, do you know how to avoid secondary wear and tear on the slitting machine?
During the operation of the slitting machine, there is often a problem of wear and tear in the transmission parts, such as wear and tear on the shaft head of the drying cylinder and the bearing chamber of the paper roll. Traditional repair methods include welding, thermal spraying, brush plating, etc., but they all have certain drawbacks: welding can cause the surface of the parts to reach a high temperature, forming deformation or cracks, and in severe cases, it can also cause shaft fracture; The electroplating coating should not be too thick, and the pollution is severe, which also limits its application. The data has good adhesion and compressive strength, which can avoid dismantling and repairing the wear of the slitting machine on site. At the same time, due to its metal deficiency concession, it can effectively absorb the impact vibration of the equipment and prevent secondary wear.
The angle between the scraper of the slitting machine and the tangent line of the mesh roller contact is usually between 15 ° and 30 °. If the angle is too large, the scraper is simply pressing against the mesh roller, and the surface of the mesh roller is not smooth. When it runs at high speed, it will cause the elastic scraper blade to vibrate or jump, causing the solution to bounce up, resulting in uneven coating amount and causing a large difference in coating amount.
The slitting machine requires the adhesive or ink substances to be evenly adhered to the surface of aluminum foil, plastic film, or fabric textiles. It has a relatively high demand for the coating process, not only requiring an average coating height, but also being able to complete high-speed non-stop roll changing to improve consumption efficiency.
