Double Shaft Slitting Machine

Double Shaft Slitting Machine

The rewinder is a special equipment for mica tape and film. The rewinding process mainly accomplishes three tasks: first, cutting off the raw paper burrs; second, cutting the whole original paper into 
a plurality of widths in accordance with user specifications; Third, control the winding diameter of the finished paper roll to meet the factory specifications.

 

Advantages of the winder
1, equipped with processing unintentional, solid, paper tube toilet paper, can instantly switch between products. 2, automatic trimming, glue spraying, sealing, and the shaft is instantaneously synchronized, so that the paper is transferred into the band saw and the paper is not damaged when it is cut.
3. Pneumatic belt feeding, double reel and each axis of the original paper have independent tension adjustment mechanism.

3. Platen roller power:
A motor that drives the platen roller by a timing belt drive is mounted on the platen roller beam. The coupling between the individual bearings of the platen roller ensures that the speed of each combined reel is the same. The speed of each part of the platen roller is the same during operation.
Platen roller photocell:
There is a photocell at the end of the platen roller beam. If the paper or any other obstacle enters the photocell illumination area, the photocell signal will immediately stop the downward movement of the platen roller. During operation, the photocell's monitoring paper does not wrap around the platen roller. If something happens, the photoelectric signal activates the alarm to stop the rewind.
Core device:
1-trache
2- top core head
3- drive motor
4- positioning stop pin
5- Safety lock in the top core lock
The core between the drums is locked before the rewinding process begins. Keep the paper roll in place during the running of the paper core locking process.
Construction
The core lock device includes a paper core plug, a cone, and a sleeve. The core of the paper core is fixed in a core seat that can be vertically up and down and can reduce friction. The core of the paper core is supported by the upper bearing of the cone, so it rotates freely. The locking of the core and the upward movement of the core locking device are done hydraulically. The vertically moving hydraulic cylinder supports the weight of the core collet so that the home can rise as the diameter of the paper roll increases. The change in the slit width is adjusted with the help of the hydraulic transfer knob. The paper core collet has a relatively low position on the locating pin. As the paper core model changes, the latch and the paper roll chuck must change. The core collet structure has a shock absorber that is lowered onto the positioning stop pin at the core of the paper core. The safety lock has a compressed air cylinder open.
working principle 
Before the rewinding begins, the collet is knocked into the paper core. The locking cylinder of the operating side core collet has a locking pressure that is less than the drive side. If the core is too long, the operating side cylinder will retract. As the size of the paper roll continues to increase, the paper core collet moves with the paper roll, preventing the paper roll from moving laterally.
Before the paper roll is pushed away from the winder, the paper core chuck is unlocked and moved to the upper position. The appropriateness of the width of the paper core collet is related to the cutter positioning device. The sensor mounted in the paper core chuck records the pulse as the spool rotates. These pulse signals are not used to calculate the paper roll diameter. There is a sensor in each side of the cone. If one side of the sensor is damaged, the other side can be used immediately.

5:Unloading table action
1- Unloading table rise position
2- Middle position of the unloader
The unloading station transfers the paper roll from the winder to the ground.
Construction
The unloader is a device mounted on the floor to remove the paper roll. The platform is controlled by a hydraulic cylinder. The platform is a steel structure. The platform hydraulic unit is equipped with a load relief valve. These are to ensure the control process of the unloading roll.
working principle 
When the paper roll is advanced onto the platform in the upper position, the platform unloads the paper roll to the intermediate position and then onto the floor, and the paper roll rolls off the platform. For safety reasons, the platform will not automatically unload paper onto the floor unless it is moved by the operator from the intermediate position to the unloading position. The reel cannot be unloaded to the floor anyway before the new rewind.
