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.
Reasons, countermeasures and effects of BOPP film slitting quality ---
On the surface, slitting is the process of dividing a film of a width into several equal or unequal width products by a cutter. The slitting process is relatively simple, but often contains mystery in simplicity, in actual production. The slitting operation is a very important part in the production of BOPP film. The quality of the slitting will directly affect the quality level of the film and affect the quality of the user. Therefore, the quality of the slitting must not be underestimated in the film production process. . Only by fully recognizing the importance of the slitting process and fully grasping the basic essentials of slitting, can we minimize consumption and ensure the best product quality, in order to fully meet the needs of customers, and provide the most reliable product quality for BOPP film. Guarantee.

4 operational requirements
4.1 Preparation before cutting:
4.1.1 Before the cutting, the paper sent from the warehouse or the semi-finished products transferred from the previous process should be checked with the “production work order” to see if the paper quality, quantity, specifications, etc. meet the requirements of the work order. If problems such as quantity or quality are found, they should be promptly submitted to the dispatcher or feedback to the squad leader. After confirmation, the logo will be clearly marked and returned to the warehouse or semi-finished product area, and the qualified products will be re-sorted for cutting. If the feedback is not received, it will be deemed as acceptance. If there are quality problems such as insufficient quantity at the end, the personnel will be responsible.
4.1.2 Lubricate the equipment according to the maintenance requirements of the machine and check whether the safety protection devices of the equipment are effective.
4.1.3 Carefully check the quality of the front and back of the paper, graphics, paper, etc., to avoid the material specifications, model or quality of the products that are put into production do not match the requirements of the cut products.
4.2.1 Carefully check the accuracy and sensitivity of the electronic scale and vernier caliper, confirm whether it meets the requirements for use, and report the abnormality in time to report with the squad leader.
