Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of spinning device relates to an oil tanker device. BACKGROUND

[0002] With the sustained growth of the market demand of industrial yarn and the continuous expansion of manufacturing capacity, the types of industrial yarn are also increasingly rich. However, in the actual production process, especially in the application of oil tanker device, a series of urgent problems have appeared. In order to improve the production efficiency, reduce static electricity and enhance the cohesion of the yarn, the prior art will use two oil tanker type oiling before the yarn enters the drafting zone, and the oil agent will flow out through the slit, so that the yarn closely adheres to the oil tanker, and the oiling is ensured.

[0003] Because a large amount of lint and flying hair (i.e. short yarn bundles scattered everywhere produced by the breakage of yarn bundles when they are wound on the hot roller due to the rotation of the hot roller) is generated when the spinning is stopped for washing the roller or the end is broken, especially when the motor bearing of the oil tanker is exposed, the yarn is easy to wind on it, and after being pulled, not only will cause the wear of the oil tanker, but also may affect the continuity and stability of the production. In addition, lint (attached to the oil box or into the oil box near the oil box when the yarn is connected), flying hair (falling into the oil box due to the scattering of flying hair), microorganisms and other things will also accumulate a large amount of putrefactive in the oil box and the pipeline, causing the oil circuit to be blocked, resulting in lack of oil and end breakage or abnormal physical properties and appearance whiteness of the cake, and thus reducing the product quality.

[0004] In patent application CN202323457210.7, a drain pipe is designed between the oil pan return pipe and the return main pipe, and the drain pipe is located at the lowest point of the oil agent overflow in the oil pan, which can completely eliminate the impurity residue at the low point. However, although the device eliminates the impurity residue at the low point, the impurities are still in the entire oil agent circulating system, and the impurities are not removed from the oil agent circulating system, and the problem of yarn winding on the oil tanker is also ignored.

[0005] Therefore, it is of great significance to study an oil tanker device to solve the above problems. UTILITY MODEL CONTENT

[0006] The utility model aims at solving the problems in the prior art, and provides an oil tanker device.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0008] The oil tanker device comprises an oil tanker, a vertical plate, an anti-winding aluminum sheet, a motor and an oil box; the vertical plate comprises an A surface and a B surface; the motor shaft of the motor is fixedly connected to the oil tanker after penetrating the A surface to the B surface; the anti-winding aluminum sheet comprises an upper anti-winding aluminum sheet; the upper anti-winding aluminum sheet is in a semi-cylindrical shell shape; the upper anti-winding aluminum sheet is arranged above the motor shaft and is fixedly connected to the B surface of the vertical plate; the central axes of the oil tanker, the motor shaft and the upper anti-winding aluminum sheet are coaxial; the part of the motor shaft exposed after penetrating the A surface to the B surface is referred to as a motor shaft A; the combination of the vertical projection of the upper anti-winding aluminum sheet and the oil tanker on a horizontal plane is referred to as a pattern X; the vertical projection of the motor shaft A on the horizontal plane is inside the pattern X; the oil box is fixedly connected to the B surface of the vertical plate and is located below the oil tanker; the anti-winding aluminum sheet further comprises a lower anti-winding aluminum sheet; the lower anti-winding aluminum sheet is in a semi-cylindrical shell shape; the lower anti-winding aluminum sheet is arranged below the motor shaft and is fixedly connected to the B surface of the vertical plate; the lower anti-winding aluminum sheet and the lower anti-winding aluminum sheet are fixedly connected and form a hollow cylinder.

The flying debris generated when the wire bundle is broken will scatter everywhere and will also wind around the motor shaft A if it comes into contact with the motor shaft A; in addition, the winding problem during the wire bundle head forming process is also not considered; the wire bundle moves from top to bottom; the suction gun below the oil tanker pulls the wire bundle into the suction gun; if the wire bundle is broken during the pulling process, the wire bundle will rebound upward and will inevitably come into contact with the motor shaft A, thereby winding around the motor shaft A.
