After the aluminum foil for pharmaceutical packaging is processed on a special aluminum foil printing and coating machine, the semi-finished product must be cut on the slitting machine. The length, width, and weight of the foil must be determined according to relevant standards. At present, the performance and technology of foreign post-press slitters are superior to those of domestic ones, mainly in the following aspects: first, advanced equipment technology, mainly manifested in the use of shaftless unwinding of raw materials, photoelectric correction of pneumatic braking, and the use of independent centers for rewinding. The roll is equipped with two upper and lower friction take-up reels. The take-up reel is made of a special structure and is assembled from an airbag felt strip and a number of friction rings. The rewinding paper core is fixed on the friction ring, and there is no contact pressure between the friction rings, so as to ensure that aluminum foil products with multiple coil sizes are collected on the same shaft. The control system of the slitting machine adopts the newer DLC and touch screen, and has automatic control functions such as calculation of inertial and friction pressure calculation working speed and winding tension characteristic curve calculation. When the pLC operation winds up the tension, it comprehensively considers factors such as diameter, speed, moment of inertia, etc. It can ensure that tension control is accurate, stable and has fault display function, and is easy to operate. Followed by high slitting speed, slitting speed up to 300 ~ 400m/min, and with a dedicated unloading device, convenient loading and unloading rolls, saving time, high production efficiency, high degree of automation. The operation of the slitter is basically completed on the touch screen, and the repeatability is good, eliminating the influence of human factors such as the operator's experience and skills. A machine has a variety of uses. The machine stores about 20,000 winding tension diameter characteristics and winding tension speed characteristics to choose from. After selecting the varix and setting various parameters, the winding tension is automatically controlled. Therefore, the machine has a wide range of adaptability, in addition to cutting aluminum foil, but also suitable for cutting PE, pp, pvc and other plastic films to meet the needs of different industries slitting products. Compared with foreign equipment, the domestic pharmaceutical aluminum foil aluminum foil slitting machine is still at a relatively low technological level. It mainly shows in these aspects: the slitting speed is low, and the domestically-made machine nominally has a large speed of 180m/mim. The speed is less than this speed. The quality of slitting and winding is not stable, because the control methods of domestic machines are backward, the control accuracy is low, and the stability and repeatability are poor. As a result, the winding quality is not stable at the time of slitting, and it is highly dependent on the experience and skills of operators. When cutting products with different widths and widths, the length of winding cannot be accurately guaranteed. However, with the efforts of recent years, with the rapid development of pharmaceutical packaging in China and changes in the market, the production capacity of slitting equipment continues to increase, and the product quality needs to be further improved. Based on the current situation of stemming, the use of manufacturers is summarized. When the slitter performance requirements, need to be re-election in the following aspects 1 to improve the production capacity of the slitter. It is generally required that the unwinding diameter should be about 1000 millimeters, the rewinding diameter should be 600 millimeters, and 7 the cutting speed can be increased. It is increased to 200-300/min based on the current slitting speed. Increasing the speed of slitting is the main way to increase production capacity. High speed is one of the main means for companies to increase output and reduce costs. 3 It is easy to operate. The increase in the diameter of the original roll, the labor intensity for the operator, the equipment must be proposed to reduce the labor intensity requirements. The unwinding system is divided into a shaft unwinding and a shaftless unwinding. Generally, there is no shaft unwinding, and the upper roll is easily clamped. As long as a lift truck is used, both the upper roll and the lower roll can be used to reduce the labor intensity. The control operation must also be simple and intuitive, such as setting the tension, tension curve, unwinding diameter, slitting material and thickness, and winding width, length and other parameters, all can be achieved through simple operation, and the equipment accuracy guarantees the winding quality. Eliminate the influence of human factors; 4 equipment is safe and reliable. When the equipment is running at a high speed, there is a certain guarantee for the safety of the operator and the safety of the operation sequence of the equipment. The corrective instrument is sensitive to ensure that the edges of the aluminum foil roll are neat and undisturbed. The number of meters is set to be stable, ensuring that the winding length deviation is within a certain tolerance range. After the aluminum foil has been printed and coated, it is necessary to carry out the post-press slitting on the slitter. The large-volume semi-finished product is cut into the required size. The semi-finished product running on the slitter is a process of unwinding and winding. This process includes two parts of the machine's running speed control and tension control. The so-called tension is to pull the aluminum foil and roll it to the core according to the standard, must apply a certain tension to the aluminum foil and tension the traction force, in which the control force of the tension aluminum foil is the tension. Tension control refers to the ability to permanently control the tension of aluminum foil as it is transported on the equipment. This control must be effective for any operating speed of the machine, including the acceleration, deceleration, and uniform speed of the machine. Even in case of emergency stop, it has the ability to ensure that the aluminum foil does not produce any damage. The slitter tension control is basically manual tension control and automatic tension control. Manual tension control means that when the winding diameter changes to a certain stage during the winding or unwinding process, the operator adjusts the manual power supply device to achieve the purpose of tension control. Automatic tension control is a tension sensor that directly measures the actual tension value of the tape, and then converts tension data into a tension signal and feeds it back to the tension controller. By comparing this signal with the preset tension value of the controller, the control signal is calculated. The automatic control execution unit makes the actual tension value and the preset tension value equal, so as to achieve the purpose of stabilizing the tension. The size of the equipment winding and unwinding tension directly affects the product yield, the tension is too large, the winding is too tight, the aluminum foil is easy to produce wrinkles, the tension is insufficient, and the aluminum foil is liable to produce a serious misalignment on the shaft, which may cause a failure. Unwinding, and causing a large swing of the reel when cutting, affect the cutting quality, so the slitter must have a good tension detection system. Solar Powered Motion Sensor Light
