Description

Technical Field

[0001] The utility model belongs to the technical field of fabric detection, and in particular relates to a detection assembly for holes in tubular fabrics. Background Art

[0002] After the tubular fabric woven by jacquard equipment comes off the machine, it will undergo a series of post-processing for testing and other purposes. It is difficult to directly observe the inner wall of the tubular fabric with the naked eye. When the effect of broken yarn / thread holes on the inner wall is greater than that on the outer surface, the hole effect cannot be discovered in time from the outer surface. Small-diameter tubular fabrics are difficult to turn over. If small defects are not detected in time but used for post-processing and application, it will not only waste the raw materials for post-processing but also cause unnecessary complaints. Currently, most of the detection is done manually by light spot detection. That is, after a light source similar to a flashlight is placed into the tubular fabric, the outside of the tubular fabric is observed with the naked eye to see if there is an obvious light spot. If there is a light spot, it means that the tubular fabric has a small hole. Utility Model Content

[0032] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples provided are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are in a very simplified form and are not in exact proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention.

[0033] like Figure 1-Figure 3 As shown, this embodiment provides a detection assembly for holes in a tubular fabric, comprising a light source component 1 and a light spot detection element 2, wherein the light spot detection element 2 is arranged beside the light source component 1, and the light source component 1 is arranged on the moving axis of the tubular fabric 6, the tubular fabric 6 moves along the moving axis and sleeves the light source component 1 therein, and the light spot detection element 2 is used to detect whether a light spot appears outside the tubular fabric 6 and is transmitted from the inside of the tubular fabric 6 to the outside. In this way, during detection, the light source component can be placed inside the tubular fabric, and the light spot detection element can be used to detect the tubular fabric outside the tubular fabric, thereby avoiding the need for staff to identify the light spot with the naked eye, thereby reducing manual labor intensity; preferably, it also includes a threaded shaft 3 and a driving component 4, The threaded shaft 3 is arranged along the direction of the moving axis, and one end of the threaded shaft 3 is conical, and the other end of the threaded shaft 3 is transmission-connected to the driving member 4, and the light source member 1 is arranged at the conical tip of the threaded shaft 3, so that the conical tip of the threaded shaft can be gradually drilled into the tubular fabric under the drive of the driving member, and the light source member is gradually moved in the tubular fabric along the direction of the moving axis, so as to perform a detailed and comprehensive inspection of the tubular fabric; preferably, it also includes a conveying member 5, which is arranged along the moving axis and close to one side of the conical tip of the threaded shaft 3, and is used to convey the tubular fabric 6 to the threaded shaft 3, so that the tubular fabric can be conveyed one by one by the conveying member to the threaded shaft, thereby further improving its degree of automation.

[0034] in, Figure 1 The middle shear head indicates the moving axis of the tubular fabric.

[0035] See Figure 3 As shown, the wall thickness of the tubular fabric 6 in the above technical solution is L, the horizontal height of the tapered tip of the screw shaft 3 is higher than the horizontal height of the conveying surface of the conveying member 5, and the height difference between the two is L. Since the tubular fabric is in a flat state when being conveyed on the conveying member, the height of the tapered tip of the screw shaft is slightly higher than the height of the conveying surface of the conveying member, so that the tubular fabric is aligned with the inner part of the tubular fabric by the tapered tip of the screw shaft at the outlet end of the conveying member, so as to facilitate insertion into the tubular fabric.

[0036] like Figure 1 and Figure 3 As shown, the conveying member 5 in the above technical solution is a belt conveyor, which has a simple structure and is convenient for feeding.

[0037] like Figure 1 、 Figure 3-Figure 6 As shown, the threaded shaft 3 in the above technical solution includes a core shaft 31 and a sleeve 32, and the sleeve 32 is coaxially rotatably installed on the core shaft 31. One end of the sleeve 32 is transmission-connected to the driving member 4, and the driving member 4 and the corresponding end of the core shaft 31 are relatively stationary. The other ends of the core shaft 31 and the sleeve 32 are cone-shaped as a whole, and the light source part 1 is arranged at the cone tip of the core shaft 31. A spiral blade 33 is provided on the outer wall of the sleeve 32, which has a simple structure, so that the sleeve rotates under the drive of the driving member, while the core shaft remains stationary.

[0038] like Figure 6 As shown, the driving member 4 in the above technical solution is a DD motor, and the driving member 4 is coaxially fixedly installed on the corresponding end of the core shaft 31, and its driving end is coaxially fixedly connected to the corresponding end of the sleeve 32. It has a simple structure and compact installation, and is more convenient to connect with the sleeve transmission. Preferably, the middle part of the core shaft 31 has a coaxially arranged wire hole 311, and the conductive wire of the light source part 1 passes through the wire hole 311 close to the end of the driving member 4, which makes the wiring of the light source part more convenient.

[0039] like Figure 4 As shown, the light spot detection element 2 in the above technical solution is a ring light source detector, which is coaxially arranged outside the light source component 1 relative to the moving axis, and the inner side of the light spot detection element 2 is a detection surface, which has a simple structure and good recognition effect on the light spot; or as Figure 5 As shown, the light spot detection element 2 in the above technical solution includes a plurality of CCD cameras 21 distributed circumferentially around the light source 1 (the method of identifying the light spot belongs to the existing technology and is not described here). It has good recognition effect and can also form images for manual re-inspection.

[0040] In this embodiment, the tubular fabric is in the form of a flattening device when being transported on the conveyor. At this time, its inner hole is in the form of a strip-shaped seam, and the direction of its inner hole is consistent with the direction of the moving axis. Although the tubular fabric is a fabric, it is soft but has a certain rigidity (slightly rigid). In this way, after the tapered tip of the threaded shaft is inserted into the tubular fabric, one end of it can be supported on the belt conveyor, and the other end can be gradually sleeved on the threaded shaft under the rotation of the threaded shaft. The length of the entire threaded shaft needs to be slightly larger than the length of the tubular fabric.

[0041] like Figure 7 As shown ( Figure 7The middle dotted line represents a schematic diagram of light emitted through the hole 61). In this embodiment, the light source, core shaft and sleeve together constitute the conical tip of the threaded shaft, and the light emitted by the light source in this embodiment can be red light, so that it has better penetration and is more easily detected by the light spot detection element (and the entire tubular fabric hole detection assembly can be carried out during the day, without the need for detection in a dark environment).

[0042] The light spot detection element in this embodiment identifies the light spot when detecting the light spot on the surface of the tubular fabric. When the tubular fabric moves to the end close to the conveyor and reaches the position of the light source, the light from the light source will pass through the corresponding end of the tubular fabric. However, its illumination area is large and will not appear in the form of a light spot. Therefore, the light spot detection element can automatically filter out the large illuminated area. When the light source is exposed from the end of the tubular fabric close to the conveyor, it can be considered that the tubular fabric detection is turned off, the driving part can stop running, and the tubular fabric can be manually removed from the threaded shaft.

[0043] In this embodiment, the inner diameter of the tubular fabric is slightly larger than the outer diameter of the threaded shaft when the tubular fabric is stretched, so that the tubular fabric can be easily retracted on the threaded shaft.

[0044] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
