Description

TECHNICAL FIELD

[0001] The utility model relates to the technical fields related to the visual inspection of the braid, in particular to a visual inspection double-sided turning device for the braid. BACKGROUND

[0002] The braid is made of various yarns into a narrow fabric or tubular fabric. The braid fabric has various types and is widely used in clothing, shoes, luggage, industry, agriculture, military supplies, transportation and other industrial departments. Common fabric structures include plain weave, twill weave and satin weave.

[0003] The utility model patent with Chinese application number CN202320203005.9 "a braid detection equipment" discloses a braid detection equipment, which includes two groups of visual inspection devices. When the braid passes through the detection device, the defect points on the braid are detected. However, the two groups of visual inspection devices detect the same side of the braid and cannot detect the other side of the braid.

[0004] When the weave structure of the braid is satin weave, the two sides of the braid are quite different. For example, when there is a broken weft defect, it is easy to be found from the back of the braid. When there is an oil point on the braid, the oil agent on the yarn will accumulate on the reed and then transfer to the warp yarn, so the oil point problem exists on the front or back of the braid. Therefore, a braid visual inspection double-sided turning device needs to be designed. UTILITY MODEL CONTENT

[0005] In view of the above technical problems, the utility model aims to overcome the problem that only one side of the braid can be detected in the prior art.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0025] like Figs. 1-2 As shown, a double-sided flipping device for visual inspection of webbing includes: a vertical mounting plate 1, a first detection unit mounted on the mounting plate 1, a second detection unit mounted on the mounting plate 1 and located next to the first detection unit with a height lower than the first detection unit, a horizontal first guide roller 2 rotatably mounted on the mounting plate 1 and located between the first detection unit and the second detection unit, and a second guide roller 3 rotatably mounted on the mounting plate 1 and parallel to the first guide roller 2.

[0026] The second guide roller 3 is located on the side of the first detection unit away from the second detection unit, and the lowest point of the second guide roller 3 is lower than the lowest point of the first detection unit.

[0027] After the webbing passes over the first guide roller 2, it will pass through the first detection unit, and after passing over the second guide roller 3, it will pass through the second detection unit. When the webbing passes over the second guide roller 3, the back side of the webbing will be facing upwards, thereby realizing the flipping of the webbing and making its back side facing upwards for detection. The first and second detection units can simultaneously detect both sides of the webbing, which not only improves detection efficiency but also makes the webbing detection more comprehensive.

[0028] The first guide roller 2 and the second guide roller 3 can rotate actively or passively. When the first guide roller 2 and the second guide roller 3 rotate actively, a stepper motor can be used to drive them so as to control the speed.

[0029] The first detection unit includes a mounting bracket fixedly mounted on the mounting plate 1, a horizontal background plate 4 fixedly mounted on the mounting bracket, a visual inspection mechanism 5 fixedly mounted on the mounting plate 1 and located directly above the background plate 4, and a limiting mechanism mounted on the mounting bracket for limiting the webbing.

[0030] The visual detection mechanism 5 is a mature technology, which generally includes a lighting lamp and a camera.

[0031] When the ribbon passes through the background base plate 4, the visual detection mechanism 5 detects the defects on the ribbon, and can cooperate with the power mechanism to stop running when the defects are detected. At this time, personnel can use a marker to circle the defects to prompt the last rolling staff to remove the defects during the rolling operation.

[0032] The power mechanism generally consists of two rubber rollers, which hold the ribbon and pull the ribbon when the rubber rollers rotate.

[0033] The mounting bracket includes a pair of material guide rods 6 parallel to the first material guide roller 2 and fixedly installed on the mounting plate 1, and at least one connecting arm 7 fixedly connected with the pair of material guide rods 6, and the background base plate 4 is fixedly assembled on the connecting arm 7.

[0034] The background base plate 4 is located between the pair of material guide rods 6, and the highest part of the background base plate 4 is lower than the highest part of the material guide rod 6.

[0035] The highest part of the material guide rod 6 is higher than the background base plate 4, which can avoid friction between the ribbon and the background base plate 4; and the background base plate 4 is generally white by default, but when a black ribbon is made of black yarn, the space between the ribbon and the background base plate 4 can also be used to place a black plate or other color plate, improving the practicability.

[0036] The limiting mechanism includes a plurality of first limiting rings 8, and two first limiting rings 8 are slidably sleeved on at least one material guide rod 6, and at least one locking bolt 9 capable of abutting against the material guide rod 6 is threadedly connected to each first limiting ring 8.

[0037] By loosening the locking bolt 9, the position of the first limiting ring 8 on the material guide rod 6 can be adjusted, and a plurality of ribbons are located between the two first limiting rings 8 to avoid deviation of the ribbons.

[0038] The second detection unit has the same structure as the first detection unit.

[0039] The highest part of the material guide rod 6 in the second detection unit is higher than the lowest part of the second material guide roller 3.

[0040] The first material guide roller 2 and the second material guide roller 3 are both sleeved with a second limiting ring 10.

[0041] The second limiting ring 10 limits the ribbon from slipping off the first material guide roller 2 and the second material guide roller 3.

[0042] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0043] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present application will not further describe various possible combinations.

[0044] In addition, various different embodiments of the present application can also be combined in any manner, as long as they do not deviate from the concept of the present application, and they should also be considered as disclosed by the present application.
