[0032] Here’s how it works:

[0033] When the circular knitting machine triangular arc symmetry detection device is to be used, the knitting needle can be placed longitudinally in advance in the placement groove 2 opened in the middle of the upper end of the base 1, and the rear end of the knitting needle will be opposite to the front and rear contact point of the dial indicator 9. Then, the locking effect can be released by unscrewing the locking ring 6 provided at the upper ends of the connecting shafts 4 on both sides. In this way, the movable plate 5 can be pushed as a whole to make the connecting shafts 4 on both sides move forward and backward along the limit grooves 3 connected at the lower ends to achieve flexible adjustment of the distance between the movable plate 5 and the baffle 7, which can be used to detect triangular blocks of different sizes. After the spacing adjustment is completed, the locking ring 6 can be tightened to lock the movable plate 5 as a whole, thereby, the triangular blocks to be tested for arc symmetry can be The corner block is placed between the moving plate 5 and the baffle 7, and the triangular block is pushed horizontally. In this way, the curved runway opened inside the triangular block will be connected to the outside of the knitting needle to realize the pushing of the knitting needle. If the triangular block is moved horizontally from the left side of the moving plate 5 to the right side of the baffle 7, it means that the arc symmetry of the curved runway of the triangular block is standard. If a jam occurs during the movement, the front contact end of the knitting squeeze dial gauge 9 will be made to rotate the pointer inside the dial gauge 9 to display the arc symmetry value. In this way, the staff can understand whether the arc symmetry of the curved runway inside the triangular block is higher or lower than the standard data through the value displayed by the dial gauge 9, so as to improve data support for subsequent reprocessing;

[0034] In order to ensure that the knitted fabric can be kept flat and avoid tilting when it is placed in the placement groove 2, a supporting and stabilizing device 10 is provided inside the base 1. That is, after the knitted fabric is placed in the placement groove 2, the adjusting rod 1052 provided inside the clamping assembly 105 can be rotated to rotate the adjusting rod 1052 to drive the connecting strip 1051 connected to the outside. In this way, the connecting strip 1051 can be moved backward along the inside of the base 1 as a whole, and the long bars 1053 connected on the left and right sides can be synchronously driven to push the long bars 1053 backward to push the slider 1054 connected to the rear side. In this way, the slider 1054 can move backward smoothly along the inside of the guide plate 1055. Because grooves are provided inside the slider 1054 and the guide plate 1055, the connecting arm 1056 located between the slider 1054 and the guide plate 1055 and connected to the grooves can be driven by the slider 1 054 is driven backward to realize the pushing of the connecting block 1057 connected to the outside, so that the connecting block 1057 drives the moving bar 101 fastened to the outside. In this way, the moving bars 101 symmetrically installed on the left and right sides of the base 1 will move relatively, so that the rollers 103 arranged at the outer ends of the three internal cross bars 102 will contact the outside of the knitting needles, so that the rollers 103 symmetrical on the left and right sides clamp the knitting needles, so that the knitting needles as a whole can be guaranteed to be in a longitudinal guarantee state, and the tilting and offset phenomenon can be avoided, resulting in the contact detection activity with the internal curved runway of the triangular block being affected. At the same time, when the rollers 103 on both sides clamp the knitting needles, the cross bar 102 can be squeezed to make the cross bar 102 stretch the compression spring 104 connected to the other side, so that the compression spring 104 provides elastic compression support to further improve the flatness of the knitting needle placement, thereby effectively ensuring the flatness of the knitting needle placement, reducing the placement offset and affecting the occurrence of detection phenomena;

[0035] At the same time, when the moving bars 101 on both sides move relative to or oppositely, in order to ensure the movement stability, a guide assembly 106 is also provided inside the moving bars 101 on both sides to realize the coordination of auxiliary support and movement guidance, that is, the support arms 1063 installed on both sides of the moving bar 101 will make the guide wheels 1064 connected to each other at the outer ends stably embedded in the guide grooves 1062 opened on both sides of the guide rod 1061. In this way, with the contact and guiding effect of the guide wheels 1064 and the guide grooves 1062, the moving bars 101 on both sides can achieve efficient and stable lateral movement. In addition, under the elastic force of the tension springs 1065 provided in the middle part of the side edges of the support arms 1063 on both sides, the support arms 1063 on both sides can have a certain clamping effect, so that the guide wheels 1064 and the inner walls of the guide grooves 1062 are stably in contact with each other. In this way, the support and movement guiding effects are significantly improved, thereby achieving the advantages of auxiliary support and lateral guidance of the moving bars 101 on both sides and deepening the clamping and stabilizing effect.

[0036] The utility model provides a circular knitting machine triangular arc symmetry detection device, by setting a supporting and stabilizing device 10, that is, through the screw transmission of the adjusting rod 1052 and the connecting bar 1051, the long bars 1053 arranged on the left and right sides of the connecting bar 1051 can push the slider 1054, and the slider 1054 can cooperate with the guide plate 1055 to drive the connecting arm 1056, so that the connecting arm 1056 pushes the moving bar 101, so that the rollers 103 arranged at three places on the side of the moving bar 101 can efficiently move the knitting needles. The clamping and resisting ensure that the knitting needles are in a flat detection state, thereby achieving the efficient guarantee of the flatness of the placement of the knitting needles, reducing the placement deviation and the occurrence of the phenomenon that affects the detection, and a guide component 106 is provided, that is, the guide wheel 1064 can be connected and cooperated with the support arm 1063, the guide wheel 1064 and the tension spring 1065 to enable the guide wheel 1064 to efficiently support the overall movement of the moving bar 101 along the guide groove 1062, thereby improving the stability of the clamping and resisting, thereby achieving the advantages of auxiliary support and lateral guidance of the moving bars 101 on both sides, and deepening the clamping and stabilizing effect.
