Preparation of slitter cutter
1. Razor slitting
1.1. The razor slitting requires the film to travel in the correct direction to the winding section.
1.2. Adjust the photoelectric tracking to bring the film to the proper position.
1.3. Tension the film and attach the blade to the razor holder.
1.4. According to the specifications required by the instruction sheet, the sliding razor holder is cut into the razor groove under the film, and the blade edge and the edge of the sipe are required to be in contact with each other.
1.5 After adjusting the depth of the cutter, lock the razor frame screws.
2. Round knife cutting
2.1. Check whether the upper and lower knives are sharp and have no gaps, and vice versa;
2.2. Determine the number of knives (N+1) according to the number of product series (N);
2.3. Install the lower knife to adjust the width of the lower knife according to the actual width of the product;
2.4 Install the upper knife correctly. The flat side of the upper knife is aligned with the side of the lower cutting edge. The upper knife is aligned with the gap between the lower knife and the septum. Press the screws on both sides to make the upper knife enter the gap depth to about 2mm. The upper knife is attached to the lower knife and fastened. Finally, the screw on the left side of the upper knife holder is adjusted so that the whole knife holder moves 1-2 mm to the right side and is fastened.
Slip axis and air shaft of slitting machine--
The inflation shaft is a special type of winding and unwinding, that is, the shaft that can be raised by the surface after high pressure inflation.
After deflation, the surface part (referring to the key bar) is quickly retracted. Its name is diversified, also known as pneumatic shaft, expansion shaft, inflation shaft, air expansion roller, inflation shaft, pressure shaft, air expansion roller, etc.
The slip axis, also known as the slip type air-up axis, is a special segmentation of the gas-increasing shaft, independent slip and torque setting structure, which will solve the unwinding phenomenon caused by the thickness and uneven tension of each roll of material. Can effectively improve product quality and work efficiency.
Slitting machine operation guide ---
4 operational requirements
4.2.1 When loading paper, it is necessary to standardize the operation. If there are products that do not meet the quality requirements, the products should be picked out and clearly marked, and feedback should be sent to the squad leader.
4.2.2 Before the official production, the crew must pass the start-up information to each other, and it is not allowed to stack debris that interferes with the operation around the machine. The captain (blocking vehicle) shall compare the trial production sample with the standard proof, and self-check the product size specification. After confirming the pass, sign the first proof, and the sample will be retained until the end of the project.
4.2.3 When cutting, it is necessary to see the product specifications and determine in advance whether the size of the slitting knife meets the product quality requirements.
4.2.4 Each group of products must be self-tested, and the quality requirements and production process control shall be carried out according to the “Product Printing Process Card”.
4.2.5 After each group of products has been cut, the product label is affixed to the self-test and the production record is filled. The products to be re-rolled are processed on the shift; the items to be treated or scrapped are labeled and transferred to the treated area or waste as required. Area. The label of each product must clearly and accurately indicate the current product status, quality or problems.
