Tape slitting machine principle：
1. The paper slitting machine shall carry out the fixed length slitting processing of the whole roll or the whole raw material, such as plastic packaging materials, packaging carton, steel plate, film, leather, wood chip, etc., and the fixed length slitting control shall be used.
2. The slitting length can be set continuously. If there is an error in the actual slitting length, it is easy to calibrate by setting parameters.
3. The slitting control of the paper slitter is divided into static and dynamic slitting: it stops accurately when the set length arrives, then static slitting processing, restarts after slitting; when the set length arrives, it does not stop. The slitting signal is dynamically slitted during the material movement process.
Reasons, countermeasures and effects of BOPP film slitting quality ---
twelve. Interface quality problem (poor interface quality, interface identifier does not match)
1. Interface requirements
Due to poor interface, the quality of the film roll may be broken or wrinkled, which may cause adverse effects in the user's use. Therefore, the film interface must be connected to the specified specification to ensure the joint quality of the interface. Specific requirements are as follows:
1 The two sections of the joint are cut and flattened horizontally, and the beige (or other specified color) adhesive tape with a width of 72 mm is firmly adhered to the front and back sides of the film;
2 In order to improve the interface quality, the film interface is required to be straight and balanced with the paper tube direction, and the interface is required to be flush and wavy. The interfaces at both ends are in the middle of the tape. Try to avoid the size of the edge. The adhesive tape is attached to the film. No obvious bubbles;
3 The film surface at the interface is required to be smooth without obvious wrinkling;
4 Do the identification of the joint position as specified.
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.
