The thermal transfer ribbon slitting machine can accurately cut the ribbon material into the required width according to the needs of the printed matter specifications. Thermal transfer printing is a printing process in which the ribbon is heated by a thermal print head, so that the ink on the ribbon melts, is absorbed by the label material, and forms a pattern. Ribbon is usually composed of ink layer, heat-resistant layer and base film, which can be divided into wax-based, resin-based and mixed-based ribbons according to the content of different ink coating materials. Ribbon slitting and rewinding machine is widely used in the slitting and rewinding of thermal transfer ribbons, fax ribbons, barcode ribbons, fax ribbons, coding ribbons and other materials.
Types of ribbon slitting machines
1. Small ribbon slitting and rewinding machine. Generally, razor slitting is used, and the smaller slitting width and unwinding diameter are generally within 500mm, and the unwinding diameter is not more than 300mm. The slitting speed is low, no more than 200 m/min, and the ribbon film grafting process is usually done in manual mode and is completed on the TTR splicing table. Equipped with 1" inflatable shaft or 1/2" inflatable shaft, it is more flexible in function, in addition to narrow slitting, it can also rewind long ribbons into short rolls and rewind 1" cores into 1/2", which is suitable for slitting finished rolls of small and medium-sized ribbons.
2. Automatic TTR ribbon slitting machine. The effective slitting width is about 1000mm, and the unwinding diameter is generally not more than 800mm. The slitting speed does not exceed 500 m/min, and the film introduction of the ribbon can be semi-automatic or fully automatic, which can save materials with the TTR splicing table. Equipped with a 1" or 1/2" inflatable shaft and a high-precision adaptive tension control system based on the diameter and speed of the film. The overall modular design, easy installation and maintenance, is suitable for high-efficiency batch ribbon slitting applications.
The process of ribbon slitting machine
This small size film roll of thermal transfer ribbon has high requirements for the slitting accuracy of the ribbon slitting machine, and there are strict restrictions on the width tolerance. TTR's base material polyester film itself is very thin, and it is easy to suffer damage during processing and affect product quality. Especially in the process of long-term operation, the ribbon needs to be kept parallel to the core when rewinding, and the accuracy of key components such as rollers and shafts may be reduced due to wear, which may cause a series of flatness problems such as stripes, wrinkles, etc., and fracture will occur when the edge is stressed too much. In addition, the slitting speed should be controlled according to the process requirements, and the speed should not be blindly increased in order to improve the slitting efficiency, and the actual work should be subdivided according to the specifications and types of different ribbons, and the process parameters should be continuously adjusted and optimized according to the quality of the finished film coil, so as to find out the best application state of the slitting equipment.
The tension control of the heat transfer ribbon slitting machine directly affects the quality of the quality of the machine. Excessive tension may cause the PET base film of the ribbon to be stretched and damaged, and even the ink layer will lose powder due to deformation, which will directly affect the final printing effect. When the tension is insufficient, it is easy to wrinkle, and there are problems such as white lines or indentations when printing. Loose winding can also lead to quality problems such as core deviation and ribbon side deviation. Therefore, the appropriate tension can ensure that the ribbon is evenly stressed in the process of slitting and rewinding, which requires the TTR slitting machine manufacturer to be familiar with the material performance and have rich debugging experience, select the appropriate tension range, and the ribbon manufacturer adjusts it according to the actual working conditions during the use of the equipment and records the process data.
Application of TTR slitting machine
TTR ribbon slitting machine has become an important production equipment in the field of labels or hang tags. In order to cut out high-quality ribbon products, thermal transfer ribbon manufacturers,In addition to having high-end TTR slitting hardware equipment with stable performance and precise control, it also needs good software support, such as a clean dust-free workshop and high-quality operators. In the process of slitting, the ribbon is easy to adsorb dust particles and form defects on the surface of the material, which affects the product quality, so the ribbon production process, including slitting, must be carried out in a dust-free environment, while maintaining the appropriate temperature and humidity to avoid the adverse effects of static electricity and dust. The operator of the slitting machine needs to have certain professional skills, not only to understand the knowledge of the ribbon, but also to be familiar with the performance and operation and maintenance methods of the equipment, to be able to avoid and remove the machine failure in a timely and effective manner, to protect their own safety in case of emergency, and then carefully analyze the cause of the failure, record the fault phenomenon, and contact the thermal transfer ribbon slitting machine manufacturer for the first time when the problem cannot be eliminated.
