Blade Adjustment, Assembly, and Maintenance Methods for Automatic Roll to Sheet Cutting Machine Blades
The blades of automatic roll to sheet cutting machines are crucial components installed in these machines. Controlled by a computer system, these machines achieve automatic cutting of various rolled materials, copper foil, aluminum foil, copper mesh, and other materials.
The quality of the blades depends largely on the material used. Blades for plastic shredders can be made of sharp steel or high-speed steel. Additionally, the manufacturing process plays a crucial role. There are two commonly used control methods for automatic roll to sheet cutting machines: programmable logic controller (PLC) + servo or stepper control system, and integrated circuit board + servo or stepper control system.
Regardless of the control method employed, automatic roll to sheet cutting machines are suitable for the automatic length or position cutting of a variety of products such as fabric, PU, leather, PVC, TPU, webbing, zippers, Velcro, adhesive foam sponge, EVA, soft plastic pipes, small wires, labels, protective film, composite materials, PET, double-sided tape, flexible circuit boards, and ribbon cables, among others. The use of microcomputer cutting machines addresses the shortcomings of slow manual cutting, inconsistent dimensions, unattractive products, and significant material wastage, making it an ideal automation solution for manufacturing and processing enterprises to save labor and improve efficiency.
When irregularities such as rough cutting edges or slight misalignment are observed, it is often related to the blades of the cutting machine. In such cases, adjustments or reinstallation of the blades can be performed using the following methods and steps.
I. Blade Adjustment Method for Automatic Roll to Sheet Cutting Machine
Turn off the power switch and exercise caution to avoid electric shock.
After installing the blade, tighten nut N while holding screw P in place with a Phillips screwdriver. Be careful not to let screw P turn with the nut, as overtightening screw P may cause difficulties in operation or jamming.
Use an L8 wrench to slowly slide the drag plate up and down to grind the upper and lower blades, helping them engage. Once the drag plate reaches the highest point, use manual blade adjustment to test-cut the material.
If the left side does not cut smoothly or has burrs, tighten nut N on the left side slightly and loosen nut N on the right side. If the issue persists, continue the above steps. If still unresolved, place paper behind the non-cutting area on the back of the blade to increase contact and area. If the right side does not cut smoothly, adjust accordingly.
II. Assembly Method for Cutting Machine Blades
Clean the blades and the contact surfaces with a clean cotton or gauze cloth.
Install the lower cold blade on the device, ensuring that the cutting edge of the lower cold blade is level with the connecting plate. Then, tighten the three fixing screws of the lower cold blade in sequence.
For ease of installing the upper cold blade, manually adjust the drag plate to the highest point and then install the upper cold blade. Do not tighten the fixing screws for the cold blade at this point.
Using the manual blade adjustment method, lower the drag plate to the lowest point and then tighten the fixing screws for the upper cold blade. Start by tightening the middle screw and then the screws on both sides.
Using the manual blade adjustment method, gradually open the cutting edges of the upper and lower cold blades. Do not fully open them but repeat this action several times to prevent burrs at the cutting edge. Finally, adjust the drag plate to the highest position.
III. Maintenance Method for Automatic Roll to Sheet Cutting Machine Blades:
Add some detergent or soap powder to carefully remove salt, grease, dirt, etc., from the blade and its rotating parts. Thoroughly clean the rotating parts, especially the blade, and then rinse with clean water. Wipe it clean with a cloth, and use a soft cloth to wipe dry. For intricate parts, wrap a thin bamboo stick or cotton swab for detailed cleaning. Alternatively, use a blow dryer with cold air to ensure complete drying.
