[0027] like Figure 1-7The circular loom defect needle detection device shown in the figure includes a circular configuration disk 2, the axis of the configuration disk 2 is colinear with the axis of the circular loom, usually in the vertical direction, so the configuration disk 2 is horizontal, and a plurality of groups of through holes 203 are provided on the configuration disk 2, and each group of through holes 203 has a plurality of through holes, and the number and relative positions of the through holes 203 in each group are the same. Generally, there are at least two through holes 203 in each group. In this embodiment, there are three through holes 203 in one group, and the three through holes 203 in one group form an isosceles triangle. The configuration disk 2 includes a horizontal mounting ring 201, and the inner wall of the mounting ring 201 has The reinforcement ring 202 extends downward, and is an integral structure with the mounting ring 201, in the shape of a coaxial circular ring. The reinforcement ring 202 is used to increase the thickness of the middle portion of the mounting ring 201, thereby improving the structural strength of the mounting ring 201 and ensuring the bending resistance of the mounting ring 201. The through holes 203 are all provided on the mounting ring 201, outside the reinforcement ring 202, so that the reinforcement ring 202 is a complete thick circular ring structure with high structural stability. Several groups of through holes 203 are equidistantly arranged around the axis of the mounting ring 201, so that the mass distribution is more uniform, and the center of gravity of the entire configuration disk 2 will be located on the axis.

[0028] An image collector 5 is provided on the configuration disk 2 to detect whether there are defective needles in the knitted product by visual means. There are also a plurality of image collectors 5, and the number of groups of through holes 203 is an integer multiple of the number of image collectors 5, and at least twice. The image collectors 5 are arranged equidistantly around the axis of the mounting ring 201, so that images of all parts of the knitted product can be obtained along the circumferential direction. The images obtained by the image collectors 5 are spliced in the computer to form an image similar to a 360-degree panoramic view. The specific structure of the image collector 5 includes a mounting plate 501, and the bottom surface of the mounting plate 501 is fixedly connected to There is a lower extension screw 502, which is parallel to the lower extension screw 502, and the number and position correspond to the through holes 203 in the same group.

After the three lower nuts 4 are tightened, the image collector 5 can be fixed on the upper surface of the mounting ring 201. The upper surface of the mounting plate 501 is fixedly connected with a protective shell 503, which has a circuit board and various cables inside. A camera 504 is arranged on the side of the protective shell 503, facing the axis of the mounting ring 201, which is the outer surface facing the knitted product.

The number of supports 1 is also several. In this embodiment, three supports are provided, and the number of groups of through holes 203 is also an integer multiple of the number of supports 1. The supports 1 are also arranged equidistantly around the axis of the mounting ring 201. The specific structure of the support 1 includes an inclined stay plate 103. The lower end of the stay plate 103 is farther from the axis of the mounting ring 201 than the upper end. In this way, when installed, the image collector 5 located at the upper end will be closer to the knitted product, the image acquisition will be clearer, and the entire detection device will be more compact after being matched with the circular knitting machine. The upper end of the stay plate 103 has a horizontal support plate 104. The upper surface of the support plate 104 is fixedly connected with an upper extension screw 105. The outer side of the upper extension screw 105 has a thread. The upper end of the upper extension screw 105 passes through the through hole 203 and is matched with an upper nut 3. After the upper nut 3 is tightened, the support 1 can be fixedly connected to the configuration disk 2. The lower end of the stay plate 103 has a foot 101. The foot 101 is usually also horizontally arranged. The foot 101 is provided with a connection hole 102 for a connecting member such as a bolt to pass through to fixedly connect the support 1 to the frame of the circular knitting machine.

[0030] Working principle: During installation, first, all the supports 1 are fixed to the preset installation positions on the frame of the circular knitting machine through bolts. Then, the configuration disk 2 is placed on all the support plates 104 and tightened with the upper nut 3. Finally, the image collector 5 is tightened on the configuration disk 2 through the lower nut 4. All the image collectors 5 are connected to an industrial computer through signal lines to form a 360° panoramic image on the computer. The computer can then automatically compare the normal images using a program to determine whether there are any abnormalities in the knitted products produced by the circular knitting machine caused by defective needles.
