What are the structural components of the wire drawing machine?
1. Winding head structure
The joint part of the main shaft of the machine head and the main body of the machine head adopts the meshing and positioning of the cone body to maintain the rotation accuracy of the machine head. The structure of the machine head is centrifugal block type, which is composed of the machine head body, the block-up block, the block-up key, the pressure spring, the front cover of the machine head, and the back cover of the machine head. The material of the entire machine head is made of aluminum alloy and stainless steel. When the machine head rotates at high speed, under the action of centrifugal force, the expansion block will support the bobbin, and the fibers will be wound on the surface of the bobbin. When the winding ends and the machine head stops rotating, the centrifugal force disappears and the expanding block falls freely to unload the drum.
2. Cable arrangement
The movement of the spiral wire spool is divided into rotary motion and reciprocating motion: the rotary motion is realized by the cabling motor through the synchronous belt drive, and the reciprocating motion is realized by the servo motor through the synchronous belt, rolling screw assembly, and linear bearing transmission. The stroke of the reciprocating movement is between 50 and 200mm, and the stroke of the reciprocating movement can be adjusted by changing the position of the two limit sensors.
3. The cable arrangement is away from the line device
The function of the untwisted roving drawing machine arranging device is to move the arranging device to the direction of the machine head at the beginning of winding; The cable reel is gradually moved to the right (also called traverse). Keep the distance between the wire and the surface layer of the silk cake unchanged, so as to ensure the same tension between the inner and outer layers of the silk cake.
4. Can changer
The can changing device is driven by the can changing motor and the air cylinder in order to rotate in the proper winding and pulling position. The motor drives the turret rotor through the reduction gear and chain until the head position detection sensor detects the stop; then the turret positioning cylinder moves to make the turret rotor rotate to the specified position and hold the stopper firmly. In order to ensure the normal progress of the wire drawing operation.
5. Oil mist lubrication device
Oil mist refers to oil particles suspended in high-speed air jets. The oil mist lubricating device is to introduce the dry compressed air from the compressed air pipeline into the oil mist generator. With the help of the compressed air carrier, the lubricating oil is atomized into fine oil particles suspended in the high-speed air jet by venturi and eddy current effects. The oil mist is delivered to each lubrication point.
6. Pneumatic device
The pneumatic device of the direct untwisted drawing machine and the untwisted roving drawing machine consists of an air pressure switch, an air pressure regulating valve, a solenoid valve, an actuator cylinder and a pneumatic pipe fitting.
7. Head brake device
Electromagnetic dynamic braking is non-contact and frictionless braking. The braking torque is large and the work is reliable. It inputs the direct current after the step-down and rectification to the stator winding of the motor, thereby generating an electromagnetic torque opposite to the direction of rotation, so as to realize electromagnetic energy consumption braking.
8. Spray device
The spray devices in the wire drawing machine include line spray and head change spray.
