Description

TECHNICAL FIELD

[0001] The utility model relates to warp knitting machine technical field, especially warp knitting machine defect cloth detection device. BACKGROUND

[0002] Warp knitting machine is the equipment that one group or several groups of parallel arrangement yarns are fed to the working needle in the warp direction to form the knitted fabric, mainly by knitting mechanism, guide bar transverse movement mechanism, warp feeding mechanism, drawing winding mechanism and transmission mechanism. When working, each group of parallel arrangement yarns has thousands of roots, if one or several roots occur broken yarn, the knitted fabric becomes defect cloth, and the broken yarn almost cannot be avoided, since the yarn is too thin and the quantity is too much, even if the broken yarn occurs, it is also impossible to visually detect. The quality detection of the warp knitted fabric woven by the warp knitting machine and the defects of the yarn raw material is mainly relied on the observation of the workers by naked eyes, which is easy to be missed, resulting in the weaving quality. Therefore, the existing technology has the problem of low weaving quality. SUMMARY

[0003] In view of the defects of the prior art, the utility model provides a warp knitting machine defect cloth detection device, which combines automatic laser broken yarn monitoring and manual eye detection of hidden problems, and the light auxiliary device for assisting manual eye detection has simple structure and low cost, but has very good use effect, and the combination of the two can effectively improve the weaving quality and reduce the production cost.

[0004] To achieve the above object, the utility model provides the following technical scheme: a warp knitting machine defect cloth detection device, including laser broken yarn monitoring device, by warp knitting machine control cabinet control, still including the light auxiliary device of auxiliary manual eye detection, the light auxiliary device includes long strip type lamp and lamp shade, long strip type lamp and lamp shade fixed connection, lamp shade and warp knitting machine box body fixed, the lamp shade includes inclined upper board, long strip type lamp fixed side board and horizontal lower board, and the lamp shade is integral type bending structure, the laser broken yarn monitoring device sets up at horizontal lower board below, with warp knitting machine frame fixed.

[0005] As a preferred, the inclination angle of the inclined upper plate is 40-60 degrees.

[0006] As a preferred, the lamp shade is fixed with the warp knitting machine box body through the angle plate and the screw.

[0007] As a preferred, the lamp shade is made of stainless steel.

[0008] The hidden problems of manual eye detection of the utility model include strip dryness problems, needle missing problems and the like.

[0009] The utility model discloses a beneficial effect: through automatic laser yarn breakage monitoring and manual eye detection secret problem combination, the light auxiliary device structure simple of supplementary manual eye detection is low in cost, but use effect is very good, and the combination of both can effectively improve weaving quality, thereby reduce production cost. The inclination angle of the inclined upper plate is 40-60 degrees, can better control the dispersivity of the light source, makes the light transmittance of the cloth surface best, and the horizontal lower plate is control light source centration better, and can control the use effect of light source not affecting laser yarn breakage monitoring.

DETAILED DESCRIPTION

[0013] The technical scheme in the utility model embodiments will be described clearly and completely below in combination with the drawings in the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0014] As Figure 1 And Figure 2 Shown, a warp knitting machine defective cloth detection device, including laser yarn breakage monitoring device 1, by warp knitting machine control cabinet 2 control, still including the light auxiliary device of supplementary manual eye detection, the light auxiliary device includes long strip type lamp 3 and stainless steel lampshade 4, long strip type lamp 3 is T8 integral lamp. Long strip type lamp 3 and lampshade 4 are fixedly connected through buckle, and the lampshade is fixed with the warp knitting machine box body 5 through angle plate 10 and screw. The lampshade 4 includes inclined upper plate 6, long strip type lamp fixed side plate 7 and horizontal lower plate 8, and the lampshade 4 is an integral type bending structure;The inclination angle of the inclined upper plate is 45 degrees. Laser yarn breakage monitoring device 1 is arranged below horizontal lower plate 8 and is fixed with warp knitting machine frame 9.

[0015] In actual use, after power on, the laser broken yarn monitoring device 1 and the light auxiliary device are started at the same time, the cloth 15 passes through the cloth pressing roller 11, the cloth outlet roller 12 and the cloth collecting roller 14, the light source of the long strip type lamp 3 irradiates on the cloth 15 between the cloth outlet roller 12 and the cloth collecting roller 14, under the irradiation of the light, some hidden defects are relatively easy to find, and the worker can find and treat immediately. The broken yarn monitoring is automatically completed by the laser broken yarn monitoring device 1, and the effective combination of the two can efficiently find the defects of the cloth 15, improve the weaving quality, and finally wind into a finished cloth roll 13.
