We know that when the variable frequency governor works at low frequency, the characteristics of the interchangeable multi-thread motor of the laminating slitter are not very good, and the excitation torque is low and fractal, so in all winding processes, the winding motor should be reduced in the work below 2HZ as much as possible. Therefore, the winding motor has a lower speed limit. The angle of contact tangent between blade and drum is generally between 15 ° and 30 °. If the angle is too large, the scraper simply rests on the drum, and the appearance of the drum is not smooth. When running at high speed, it will cause the vibration or jump of the elastic blade, make the solution rebound, form an uneven coating amount, and cause the difference in coating amount.
日期：2023-03-06The so-called automation of slitter equipment is mainly reflected in the feeding, shearing system and shearing part. Both the feeding and discharging are equipped with storage racks, while the shearing system is a PLC control system. Its function is to record and display the current working parameters and status, as well as the memory and storage of material parameters, hot rolling faults and other powerful functions. Most users will encounter some common phenomena when using the blades of polarizer slitting machine, which will reduce the efficiency of the machine and reduce the whole working process. Let's look at the specific situation and how we should adjust it. Strip steel metal coils, such as strip steel, stainless steel, copper... are mainly used in steel processing plants, steel market operators, steel rolling manufacturers, electrical industry, automobile, stamping parts, etc. Due to the high accuracy of the stripper in the process of manufacturing and assembly, it is impossible to select the motor with large power in the process of processing and assembly, but it is not considered.
日期：2023-03-06The slitter adopts spring pressure, and the paper pushing adopts slider structure. The structure is simple and the debugging and maintenance are convenient, but the paper pressure is low and the cutting accuracy is poor, which can not meet the requirements of cutting accuracy for advanced printing, and also can not meet the requirements of medium and high-end packaging printing products. When selecting the cutting machine, you should select it according to the actual situation of the products you want to process. According to the high-speed operation of the round knife, the original waterproof material is divided into multiple rolls of narrow waterproof material. The slitting method of the adhesive slitting machine is widely used in the adhesive product manufacturing industry. Inclination correction equipment shall be installed on the slitting machine to make as few modifications as possible to the existing equipment and put forward clear corrective measures.
日期：2023-02-28The purpose, working principle and characteristics of the optical film coater: The optical film coater is used for coating BOPP sealing tape. A layer of glue, pigment or ink with specific effect is coated on the rolled substrate, then dried, and then rolled up. It accepts a special high-speed coating head, which can be used to reduce the appearance of bubbles. The take-up and unwinding of the optical film coater are equipped with a full-speed automatic film receiving mechanism, and the tension closed-loop automatic control.
日期：2023-02-28The air expansion shaft (air expansion shaft) driven by the slitter is divided into key-type air expansion shaft (air expansion shaft), plate-type air expansion shaft (air expansion shaft) and slip shaft.
日期：2023-02-20Type of stripper: 1. Parallel blade shear. The two blades of this shear are parallel. It is usually used for transverse cutting of blooms (square slabs) and other squares. Billets with rectangular section are also called billet shears. This kind of shear sometimes also uses two forming blades to cold shear rolled parts (such as round tube blank and small round steel, etc.). At this time, the shape of the blade is compatible with the section shape of the workpiece to be sheared.
日期：2023-02-20The optical film coating machine comprises a frame, a rear roller mechanism arranged on the frame, a feeding roller mechanism, a hopper mechanism and a scraper. The hopper mechanism of the product has inverted trapezoidal column layout, inverted triangular column layout and approximate semi-cylindrical layout, and the hopper mechanism is equipped with coating agent; The feeding roller mechanism of the product is soaked and fixed in the hopper mechanism; By changing the cylinder form of the feeding mechanism, the height of the feeding mechanism on the rack is increased, so that the height of the feeding roller is not easily lower than the liquid level of the coating agent, which ensures the coating agent and saves the coating agent. The layout of the optical film coating machine is simple and reasonable, the coating is high and uniform, and the finishing is convenient.
日期：2023-02-11As a kind of gravure coating, the micro-cavity coating machine belongs to roller coating. The difference between it and gravure coating mainly lies in the gravure roller diameter, back roller and the movement direction of gravure roller and substrate. With the increasing market demand for high functional films and the popularization of wet coating technology, the micro-cavity coating machine will be widely used in the high-end functional film deep processing industry.
日期：2023-02-11In fact, the working principle of the slitter and the slitter is different. In the case of the slitter, the wide material is divided into the desired width through a fixed or rotary knife, while in the case of the slitter, the material is cut into the desired width according to the movement of the cutting knife.
日期：2022-11-22The coating machine extrusion coating is to apply the molten mesh of synthetic resin onto the base material. It is a multi-functional coating technology, which is used for the economic application of various plastics, especially polyethylene, cardboard, corrugated fibreboard, paper, aluminum foil, cellulose, non-woven fabric or plastic film. What are the characteristics of the coating extrusion technology? Today we tell you:
日期：2022-11-221. The overall installation accuracy is low, Solution: If the installation center of each component deviates from the design center line of the whole machine or has an included angle with the design center, the foil strip will be seriously wrinkled, and the installation center must be adjusted.
