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)
2. Interface identifier
Due to the large thickness of the film interface, the film roll for some applications must be properly handled at the interface to avoid unnecessary problems, such as slowing down, increasing the gap between the coating blade, and printing the offset plate. The interface products must be identified as necessary to facilitate customer identification and internal management.
1 The color of the adhesive interface is generally beige, special requirements are used according to the regulations. For example, Shanghai Ziquan requires the use of black adhesive tape; the marking method of the joint position is operated according to the regulations, such as Zhuhai Zhongfu Pearl Film, Shenzhen Ruimei The hot film is required to be marked at the ends of the interface with yellow paper dust protruding from the end of the film roll by about 1 cm; other special marks are operated according to the requirements of the production tribe.
2 Require the slitting workshop to mark the length number of the joint product without special requirements after the length of the label in the length column of the package label, and mark the “buter” mark on the note bar of the computer, and mark “+” on the remark column. Marking, pearl film and imitation paper film and exporting pearl film should indicate the length of each product before and after the joint on the length column of the product specification. For special requirements, the relevant marking work should be done according to the regulations (such as Shanghai Ziquan product port). The rate of less than or greater than 25% requires the number of interface products on each board product).
Slitting machine operation guide ---
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.
