Description

Technical Field

[0001] The utility model relates to the technical field of knitting equipment, in particular to a knitting density regulating device. Background Art

[0002] Knitting density adjustment is mainly used to control the density of knitted fabrics, that is, the number of knitted loops per unit length. Knitting density directly affects the thickness, elasticity, breathability and appearance of knitted fabrics. By adjusting the knitting density, knitted fabrics of different thicknesses and weights can be produced to meet different application requirements. Appropriate knitting density can improve the elasticity, breathability and durability of the fabric, thereby improving the performance of the final product.

[0003] In the process of adjusting the knitting density, it is usually necessary to replace the knitting needles of different lengths according to the actual situation. The knitting needle length determines the length of the yarn used in each coil. Longer knitting needles will result in longer coils, thereby reducing the number of coils under the same fabric width, thereby reducing the knitting density. Shorter knitting needles will result in shorter coils, thereby increasing the number of coils under the same fabric width, thereby increasing the knitting density.

[0004] Currently, when adjusting the knitting density, although the length of the knitting needles can be adjusted by replacing the knitting needles, this method requires the purchase and maintenance of knitting needles of different lengths, thereby increasing production costs. The time spent on replacing the knitting needles is relatively long, which further increases the time for adjusting the knitting density. Moreover, replacing the knitting needles may require specific skills and training, which increases the complexity of the operation. Therefore, we propose a knitting density adjustment device.

The worm 58 is rotatably connected to the front side of the top wall of the shell 1. The worm gears 57 are arranged on the front side of the outer arc surface of the mounting rod 55. The two worm gears 57 are meshed with the worm 58. The adjusting mechanism 5 also includes an adjusting wheel 59. The adjusting wheel 59 is arranged at the upper end of the worm 58. The hexagonal sliding column 51 is driven to move through the cross plate 52, and then the hexagonal sliding column 51 is used to adjust the length of the knitting needle 3 through the needle cylinder 2, thereby reducing or increasing the knitting density, replacing the traditional method of adjusting the knitting density by replacing the knitting needle. There is no need to replace the knitting needle 3 back and forth, which reduces the production cost and shortens the adjustment time, further improving work efficiency.

When the tip of the knitting needle 3 passes through the fabric to be sewn, a small coil is pulled out from one side of the fabric to the other side. A device under the fabric (such as a shuttle) will grab this coil and wrap it around another thread or another coil of the same thread to form a lock, thereby realizing knitting work. When the knitting density needs to be adjusted, The operator rotates the adjusting wheel 59, and the adjusting wheel 59 drives the worm gear 57 to rotate through the worm 58, and the worm gear 57 drives the connecting plate 56 to rotate through the mounting rod 55. During the rotation of the connecting plate 56, the adjusting rod 54 slides inside the adjusting slot and rotates relative to the adjusting slot, so that the connecting plate 56 drives the fixing seat 53 to move through the adjusting rod 54, and the fixing seat 53 drives the hexagonal sliding column 51 to move through the cross plate 52, so that the hexagonal sliding column 51 adjusts the length of the knitting needle 3 through the needle cylinder 2. The length of the knitting needle 3 determines the length of the yarn used in each coil. A longer knitting needle 3 will result in a longer coil, thereby reducing the number of coils at the same fabric width, thereby reducing the knitting density.
