Description

Spandex yarn winding head

The present invention relates to a forming apparatus in a spinning apparatus, and more particularly to a spandex winding head. Background technique

At present, spandex production mainly uses continuous polymerization and high-speed spinning continuous production process. The whole production process is mainly divided into four processes: A. Polymerization process B. Spinning process C. Post-treatment process D. The spinning process mainly means that the raw liquid conveyed from the spinning tank is supplied to the spinning assembly through the gear metering pump. After being ejected through the spinneret, it enters the spinning path, and the original liquid solidifies into a tow. After false twisting and oiling, the bobbin is wound into a certain weight on the winder. The winding head is the most important equipment in the spinning process. It has high speed, complicated manufacturing and processing, accounting for about 60% of the cost of the spinning process. It is the most important production equipment in spandex production.

In the prior art, the function of the spandex winding head is to wind the spandex filament into a certain weight of the bobbin (commonly known as silk cake), mainly by the power head 3, the contact roller 10, the traverse guide wire device 9, the volume The winding roller 1, the turntable 2, and the electric control device are constructed. Referring to Figures 8 and 9, Figure 8 is a front view of the prior art, and Figure 9 is a left side view of Figure 8. Each winding head has two winding rollers. When the wire wound on one winding roller reaches a certain weight (full volume), the turntable (with the winding roller on the top) starts to rotate, automatically switching The spinning is continued on another winding roller (the empty roller to be wound), which is generally referred to as a fully automatic switching winder. As spandex accounts for the expansion of the chemical fiber market, spandex manufacturers are increasingly fierce. In recent years, in order to increase production, the winder has a tendency of multi-thread cake, which means that the output of finished silk per unit time increases, and the production cost But there are not many changes. It meets the goal of maximizing the production capacity of spandex manufacturers. However, this trend has been limited, mainly because the winding roller itself is lengthened, and the godet roller associated with the winding head is also lengthened. The processing difficulty of the winding roller is greatly improved, and the vibration and noise of the winding head itself are remarkable. Increased consistency in the formation of spandex cakes is difficult to guarantee. SUMMARY OF THE INVENTION A novel spandex winding head that significantly increases the production of a single-unit spandex yarn with greater utilization of machine space.

The object of the present invention can be achieved by the following technical measures:

The spandex winding head of the invention comprises a power head mounted on the frame, and a turntable rotating on the front end of the power head is arranged on the front end of the power head, and the front end surface of the turntable is parallel along the central axis of the turntable There are two winding rollers which can be rotated forward in a cantilever manner and can rotate around their own axes. A sliding box is arranged above the turntable, and the rear end of the sliding box passes through a guiding column disposed in the power head box body and is used for driving sliding. The lifting cylinder of the box moving up and down along the guiding column is installed at the front end of the power head, and the front end of the contact roller bearing and the traverse guide wire device are arranged side by side in the cantilever structure at the front end of the sliding box, in contact with the roller branch a seat roller is mounted along the length thereof and a high-speed rotary power unit for driving the contact roller around its own axis, wherein the front end of the power head is provided with two left and right center axes that can extend in a horizontal direction. The turntable, and the rotation directions of the two turntables are opposite; on the front end face of each turntable, two cans are arranged in parallel along the central axis of the turntable. a front-extending winding roller rotatable about its own axis; two forward-facing contact roller holders are mounted side by side in a cantilever manner at the front end of the sliding box, and one of each of the contact roller holders is mounted along its length a contact roller and a high-speed rotary power unit for driving the contact roller around its own axis, the traverse guide wire device being disposed between the left and right contact rollers, and on the left and right sides of the traverse guide device A traverse guide is provided. Since there is only one set of the traverse guide wire device according to the present invention, the left and right contact rolls share a set of traverse guide wire devices, and the design of the structure can greatly reduce the width of the power head. The structure is more compact, and the silk path is in the middle of the two turntables, which can sufficiently reduce the spacing of the two turntables and fully improve the space efficiency in the left and right direction.

The rotary motion of the left and right two turntables arranged side by side in the present invention is driven by a motor by mutually engaging a pair of gears and meshing with one of the two gears respectively mounted on the two turntable drive shafts. Dynamic drive gears are used to achieve this.

The working principle of the winding head of the invention is as follows: Starting from the winding of the winding roller, as the diameter of the wire cake is gradually increased, the sliding box starts to gradually move upward, and the contact pressure between the contact roller and the winding roller is controlled by a precision. Controlled by a pressure regulator. When the cakes respectively wound on a winding roller of the respective turntable reach a certain weight (full roll), the sliding box moves up again, and then the two turntables start to rotate, so that the other one on the respective turntable The winding roller is rotated from the position to be wound to the normal spinning position, and the full winding roller is turned to the lower unwinding zone to complete the entire switching operation. The rapid upward movement of the sliding box is realized by lifting the gas rainbow (at this time, the gas is driven by the high-pressure air), and the contact roller during the normal spinning is the driving roller (drag by the synchronous motor), and is pressed against the winding roller with a certain contact pressure. Above, driving the winding roller to rotate at a constant linear velocity, since the contact pressure between the two contact rollers and the two winding rollers is kept equal, the filaments are symmetrically distributed on both sides of the traverse guide wire device, so the quality of the spun spun yarn is Can be guaranteed. The rotation directions of the two contact rollers are opposite, and the rotation directions of the two winding rollers are opposite. When the diameter of the wire cake reaches the set value required by the process, the turntable should simultaneously drive the winding roller to switch, in order to avoid two rolls. The silk biscuits wound around the rolls are involved. When switching, the silk cakes are rotated around the axis of the turntable and respectively rotate to the two outer sides of the power head. Therefore, the rotation directions of the two turntables are also opposite, and the rotation of the two turntables is reversed. It is dragged by a set of drives.

Compared with the prior art, the invention adopts two turntables, four winding rolls and one set of traverse guide wire device, so that the structure is compact, the space use efficiency is maximized, and the space is ensured. The lengths of the silk paths on both sides of the guide wire device are equal, and the deflection angles are equal, thereby ensuring the same tension of the spandex yarn, and a better shape of the cake can be obtained. The output of the winder is doubled under the same process conditions, reducing the equipment investment cost of the spandex manufacturer. DRAWINGS
