What Mechanical Accessories Are Required For Plastic Film, Printing, Packaging Materials, And Paper Winding And Unwinding Processes?

The winding and unwinding process is very important to industrial production, which can improve production efficiency, reduce production costs, ensure product quality, promote enterprise development, and bring important guarantees for the sustainable development of enterprises.

The winding and unwinding process in plastic film, printing, packaging materials, paper have applications in many other industries. Its specific operation requires the following mechanical spare parts:

1. Unwinding and unwinding equipment: including winding and unwinding machine, air expanding shaft, winding and unwinding roll, etc. These machines are used to put away materials smoothly and avoid unnecessary difficulties and damage.
Among them, the commonly used air expansion shaft is leaf type air expansion shaft, lug type inflation shaft, through long key type air expansion shaft(multi bladder type air shaft), and the specific required size can be customized to PRE Co.,Limited.
If the existing inflatable shaft size cannot meet the existing needs, the inflatable shaft adapter can be customized to meet the conversion of different coil shafts.

2. Cutting equipment: In the process of material processing, it is necessary to cut for different products to ensure the accuracy of product size. Cutting equipment includes cutting machines, knives, etc.

3. Web guiding system: In order to avoid the deviation of the material during the retracting process, a guide device is required to maintain the proper position of the film. Including: guiding controller, guiding sensor, rectifier actuator, etc.
Among them, there are two commonly used guiding controllers: EPC edge controllers and LPC line controllers. There are two commonly used guiding sensors: ultrasonic sensors and photoelectric sensors. The rectifier is available in 6 models at PRE Co.,Limited.

4. Tension control system: to ensure that the quality of materials, such as dimensional accuracy (thickness, width, cross-section shape, etc.), straightness, winding tightness, shape and material performance, etc. meet the standard requirements. Includes: tension controller, tension sensor, magnetic powder clutch.
Among them, in the process of choosing a tension sensor:

• Need your own machinery suitable for which installation method, tension sensor in PRE Co.,Limited can choose two series: foot pressure sensor LX series and through-hole tension sensor LC series.
• According to their own aperture, flange size, choose the right model, in PRE Co.,Limited there are 4 models to choose from.

5. Magnetic powder brake or pneumatic brake: its use is also buffer starting or stopping, tension control, continuous sliding, adjusting the operating speed of winding and unwinding equipment, etc.

• According to the electromagnetic principle and the use of magnetic powder to transmit torque, magnetic powder brake has the characteristics of excitation current and transmission torque basically linear relationship. In the case of independent slip, it can transmit a certain torque, and has the advantages of fast response, simple structure, no pollution, no noise, no shock vibration and energy saving. It is a multi-purpose, superior performance automatic control element. Now it has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet press and other related winding processing industries in unwinding and winding tension control. Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery.
• Pneumatic brake, referred to as disc brake, pneumatic brake, air disc brake and air pressure hydraulic pneumatic brake, etc., belongs to one of the industrial transmission brakes, is the use of air pressure to stop or slow down the moving parts in the machinery of the actuator. Simple structure, easy installation, not easy to damage, anti-compression, anti-fall and anti-knock, long service life, generally only need to replace the brake pads.
• Among them, in the process of selecting magnetic powder brake and pneumatic brake, you need to choose the appropriate size brake according to the weight and torque demand of your own materials, in PLE, magnetic powder brake has PRE-B1 hollow shaft shell rotary magnetic powder brake and PRE-B single-shaft magnetic powder brake is available, pneumatic brake has DBG hydraulic disc brake, DBH pneumatic clutch brake and DBF air disc brake are available.
  

6. Cutting equipment: used to cut large pieces of plastic film into the required size. Cutting equipment includes cutting machines, tools, etc.
