The horizontal pneumatic type winding / reeling machine with good performance
The Horizontal pneumatic type winding / reeling machine is matched with a paper machine with the same net paper width, and is used to roll the paper into a tight and uniform roll.
During operation, the paper roll roller abuts on the rotating paper roll cylinder and is driven to rotate by surface friction. The line pressure between the paper roll and the paper roll cylinder can be adjusted by controlling the intake air pressure of the cylinder and the main arm cylinder through the console. Therefore, it can meet the needs of different paper types, so that the paper can be rolled into a tight and uniform roll.
Because the paper roll roller is purely driven by the friction of the surface of the paper roll cylinder, as the diameter of the paper gradually increases, the speed of the paper roll is correspondingly reduced, and no additional speed adjustment is required, which is convenient to operate.
This series of products are divided into left and right arrangement according to the transmission position. Standing at the end of the paper roll to face the machine. The device located on the left side is called the left mobile phone (represented by the letter Z), and the user should pay attention to the same direction as the paper machine used

This series of products are made of the corresponding paper roll cylinder, paper roll, stretching device, scraper, connecting shaft and main arm, jib transmission, frame, pneumatic operation box, paper roll brake, paper shelf, electrical equipment etc.
1. Roll paper cylinder device:
The device is composed of a gas-water rotary joint, a transmission side bearing, an operation side bearing, and a paper roll cylinder.
2. Paper roll device
The device is composed of a fixed-end bearing, a floating-end bearing, a half coupling, a paper roll and the like.
The paper roll consists of a bulkhead, a shaft head, a roller body and a bearing, a semi-coupling, etc. After assembly, it is fully calibrated and balanced to meet the needs of high-speed rotation on the paper rewinding frame of the rewinder.
3. Stretching device
The device consists of a movable arc-shaped roller and a supporting frame foot. Its role is to make the web fully stretched before entering the roll cylinder to avoid folding and wrinkling during winding.
In order to keep the surface of the paper roll cylinder constantly clean, a scraper device is provided. It is fixed on a bracket inside the rack. A handle connected to the blade head of the scraper body is provided on the outside of the operating side frame, and the scraper can be lifted by pulling it, so as to regularly clean up the dirt on the blade edge.
5. Jib device
The jib device is composed of a jib, a fan gear, an air cylinder and a pressure rod. The whole device is sleeved on the two bearing seats of the paper roll cylinder, and can be driven by the jib transmission device to rotate around this bearing. Its main function is to catch a new paper roll at a starting position tilted 20 ° forward and move it to a level of about 45 ° from the horizontal (for cardboard, this angle is about 60 °). Roll position, after the unwinding is completed and the paper web is normally rolled up, move it to the horizontal rail of the rack as soon as possible.
In this process, for the sake of safety, the paper roll roller is always pressed against the paper roll cylinder to generate the necessary pressure of the paper roll line, so that the paper roll does not jump when the paper is rotated, the paper web does not wrinkle, and the paper roll is tight Even and moderate tightness, two auxiliary cylinders are equipped. Especially when the paper roll is moved to the horizontal guide without being caught by the main arm, the roll paper line pressure due to the component force generated by the paper roll's own weight has dropped to zero. At this time, the required line pressure is completely It is realized by the auxiliary cylinder until all the main arms are connected to the main body. That is to say, at this time, the auxiliary cylinder can be depressurized, and the pressure lever can be retracted. When the diameter of the paper roll increases, the paper roll roller bearings are all moved away from the shorter side of the jib fork about 15mm, the jib can be raised to the starting position to accept the task of the next cycle.
The pressure of the roll paper line varies depending on the paper type, which can be achieved by adjusting the intake air pressure of the cylinder through the operating table.
The main arm device is composed of a main arm, a turning mechanism and a cylinder. The main arm can be rotated around the support fixed to the bottom rail (commonly known as the base plate) by the cylinder pushing or pulling. Its main function is to hold the paper roll on the jib and continuously apply pressure to it, so that a certain linear pressure is generated between the paper roll and the roll cylinder, so as to ensure the tightness of the paper roll. This line of pressure can be realized by adjusting the inlet pressure through the operating table according to the needs of the paper type. After reaching the predetermined maximum roll paper diameter, push the roll back. Then return to the starting position to "execute" the next cycle of work.
The main arm is provided with a turning mechanism, which guarantees that under any circumstances, that is, whether the jib first moves the paper roll to the horizontal guide, and then the main arm comes over to catch it, or the main arm waits for the Start position, and then the jib moves the paper roll to the horizontal guide rail, which can achieve the purpose of catching smoothly
7. Jib transmission
The jib transmission is composed of a motor, a worm gear reducer, a safety clutch, a pinion, and a connecting shaft. The rotation of the jib is realized by this system. According to the technological requirements and structural arrangements, the jib catches the new paper roll at the starting position inclined 20 ° forward, and the roll surface of the paper roll is in contact with the cylinder surface of the paper roll when it is rotated backward about 32 °. By the friction of the cylinder surface, the linear velocity is equal to the linear velocity of the paper roll cylinder, and the paper is drawn up. After the full width of the paper web is drawn in and normal, you can lower it evenly and move it on the horizontal guide rail of the rack. As mentioned above, when the paper roll roller bearings are all moved about 15mm away from the shorter side of the fork of the jib, the motor can be reversed to return the jib to its starting position with no load.
In order to prevent the paper roll from moving forward due to inertia after the power of the motor is cut off, that is, the action is delayed, a brake is arranged at the high speed shaft so that once the power is cut off, the entire transmission system is stopped. Considering that when the jib with the rolled paper roll (paper roll) is lowered to the horizontal rail at a uniform speed, once the stroke switch fails, the motor continues to run in the same direction, the gearbox will be damaged due to excessive load, and the motor will be damaged. Or break the fork of the jib, so a safety clutch is also set, that is, it automatically slips when the load is too large, which plays a protective role
The device is composed of front and rear supports, horizontal guide rails, bottom rails, etc., and supports most parts. To ensure safety, protective railings are provided.
9.Paper roll brake
The paper roll brake is used to stop the rotating paper roll before lifting. So that the journal of the paper roll is not severely worn due to being suspended due to rotation. The brake is fixed on the outside of the rear support of the machine frame (for wide and high speed), and a space is provided on the inside for pneumatic braking, which is conducive to the operation of the lifting hook. It uses the friction torque between the friction plate riveted on the brake plate and the half couplings fixed at both ends of the paper roll to brake the entire paper roll.
