Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment and relates to a grey cloth oil needle cleaning device. Background Art
[0002] In order to reduce the friction coefficient between the knitting needles and various components, extend the service life of the knitting needles (sinkers), cams and needle cylinders, reduce the heat generated by friction and keep the knitting machine running at an appropriate temperature during high-speed operation, special lubricating oil needs to be added.
[0003] Knitting oil is an emulsified oil and can generally be removed. However, many fabrics, especially spandex fabrics, are pre-dyed and it is difficult to remove the oil needles after being exposed to high temperatures. Therefore, it is necessary to control the oil needle situation of the grey fabric.
[0004] Formation of oil needles: During the production process of circular knitting machines, the knitting needles continuously move up and down in the needle groove under the action of the triangular needle channel. At the same time, the knitting needles also have to make circular motions with the syringe. There is constant friction between the needle bar and the needle groove of the syringe, and between the needle bell and the triangle. In this process, trace amounts of iron filings are continuously produced, mixed with lubricating oil and brought to the top of the needle or the needle groove under the influence of the lifting and lowering motion of the knitting needle. They are adhered and adsorbed by the yarn in the process of the knitting needle bending the yarn into a circle, thus forming oil needles on the grey cloth.
[0005] The formation of oil needles is not only affected by the amount of oil, but also related to the type of yarn and the roughness of the surface of the machine parts. No matter what the cause is, it will affect the quality of the grey cloth, and in severe cases it may even cause the grey cloth to be scrapped. Utility Model Content
[0006] The purpose of the utility model is to provide a grey cloth oil needle cleaning device in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to clean the grey cloth oil needle by blowing.
[0007] The purpose of the utility model can be achieved through the following technical solutions: a grey cloth oil needle cleaning device, characterized in that it includes a base, a support rod fixed on the base, an air nozzle connected to the top of the support rod and an air pipe connected to the air nozzle, the air pipe is connected to an air source, and the air outlet of the air nozzle is flat with a contracted middle part.
[0008] Furthermore, the support rod is a bendable rod formed by connecting a plurality of active knots in series.
[0009] Furthermore, a permanent magnetic material is fixedly arranged on the base.
[0010] Furthermore, the air pipe is fixed on the support rod through a plurality of clamps.
[0011] Place the base on the large disc of the circular knitting machine, align the air jet nozzle with the top of the oil needle of the green fabric, and blow air downward to clean the oil needle. Specifically, the air jet nozzle can be directly opposite the edge positions of the upper needle disc and the lower needle cylinder to avoid interference and can effectively clean the oil needle. Blow the oil stains attached to the needle grooves of the lower needle cylinder and the surfaces of its knitting needles downward and let them flow into the waste oil pot along the lower oil guide groove. At the same time, blow the oil stains attached to the needle grooves of the upper needle disc and the surfaces of its knitting needles inward and let them flow into the waste oil pot along the oil guide groove, preventing the oil stains from adsorbing onto the surface of the yarn to form oil needles, thus avoiding the borrowing and scrapping of the green fabric. Since the air jet position changes continuously with the rotation of the large disc, the air jet nozzle can cover all the cleaning positions. In addition, due to the contraction in the middle of the air jet nozzle, the air flow intensity ejected by the air jet nozzle is in a state where it is relatively rapid in the middle and relatively slow on both sides. During the action on the cleaning part, the part to be cleaned can be affected by both the strong air flow and the slow air flow, which is beneficial to the cleaning effect, and the air jet pressure basically does not need to be adjusted on the air source side. Description of the Drawings

[0013] In the figure, 1 is the base; 2 is the support rod; 3 is the air jet nozzle; 4 is the air pipe. Detailed Embodiment
[0014] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0015] As Figure 1 shown in the cleaning device for the oil needle of the green fabric, it includes a base 1, a support rod 2 fixed on the base 1, an air jet nozzle 3 connected to the top of the support rod 2, and an air pipe 4 connected to the air jet nozzle 3. The air pipe 4 is connected to the air source. The air outlet of the air jet nozzle 3 is in a flat shape with a contraction in the middle; the support rod 2 is a bendable rod formed by connecting multiple active knots in series; a permanent magnetic material is fixedly arranged on the base 1; the air pipe 4 is fixed on the support rod 2 through multiple clamps.
[0016] Place the base 1 on the large disk of the circular knitting machine, align the air nozzle 3 with the top of the oil needle of the green fabric, and blow air downward to clean the oil needle. Specifically, the air nozzle 3 can be directly opposite the edge positions of the upper needle plate and the lower needle cylinder to avoid interference and can effectively clean the oil needle. Blow the oil stains attached to the needle grooves of the lower needle cylinder and the surfaces of its knitting needles downward and flow them into the waste oil pot along the lower oil guide groove. At the same time, blow the oil stains attached to the needle grooves of the upper needle plate and the surfaces of its knitting needles inward and flow them into the waste oil pot along the oil guide groove, avoiding the adsorption of oil stains onto the surface of the yarn to form oil needles, thereby preventing the green fabric from being cut or scrapped. Since the air blowing position changes continuously with the rotation of the large disk, the air nozzle 3 can cover all the cleaning positions. In addition, due to the contraction of the middle part of the air nozzle 3, the air flow intensity ejected by the air nozzle 3 is in a state where it is relatively rapid in the middle and relatively slow on both sides. During the action on the cleaning part, the part to be cleaned can be affected by both the stronger air flow and the slower air flow, which is beneficial to the cleaning effect, and the air blowing pressure basically does not need to be adjusted on the air source side.

Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
