Three-dimensional vamp machine

Abstract

The invention discloses a three-dimensional vamp machine, and belongs to the technical field of knitting machines. The three-dimensional vamp machine comprises an upper needle cylinder, a lower needlecylinder, a large tripod and a large disc, wherein the upper needle cylinder and the lower needle cylinder are coaxially distributed; the large tripod and the large disc are used for mounting the upper needle cylinder and the lower needle cylinder; a transmission mechanism is arranged on one side of the large tripod and the large disc; large disc gears with the same number of teeth are arranged on the inner side of the large tripod and the inner side of the large disc; the transmission mechanism drives the upper needle cylinder and the lower needle cylinder to rotate in the same direction through the large disc gears; the end, close to the large disc, of the transmission mechanism is in transmission connection with a servo motor used for driving the upper needle cylinder and the lower needle cylinder to rotate forwards and backwards; upper needles and lower needles are arranged on the outer circumference of the upper needle cylinder and the outer circumference of the lower needle cylinder respectively and are oppositely arranged in a one-to-one mode. Two-sided jacquard weaving of the fabric can be achieved, and meanwhile, single-sided jacquard weaving and double-sided jacquard weaving can be switched at will according to needs, so that the diversity of vamp knitted fabric weave is improved, different production requirements are met, and the defect that a traditional small circular knitting machine cannot achieve double-sided jacquard weaving is also solved.

Description

technical field [0001] The invention discloses a three-dimensional vamp machine, which belongs to the technical field of knitting machines. Background technique [0002] In the field of knitting technology, the circular weft machine is the most common type of knitting equipment. Its main function part is the loop forming system, including the needle cylinder. There are needle grooves on the needle cylinder. The needle is driven by the cam to move along the needle groove to realize the narrowing and widening of the needle to complete the loop forming process. [0003] The double-sided fabric not only has the advantage of being thicker than the single-sided fabric, but the double-sided fabric structure can realize more kinds of fabric structures and patterns by designing different needle-out rules for upper and lower needles, which has obvious jacquard advantages . There are two kinds of circular weft machines for weaving double-sided fabrics, one is a double-cylinder single...

Problems solved by technology

Although this invention patent discloses the specific alignment structure of the upper and lower knitting needles in the double-sided circular weft machine, it can be distinguished from the knitting structure other than the traditional double-sided circular weft machine, and is applied to the small circular knitting machine for double-sided fabric weaving , but according to the jacquard structure of the traditional circular weft machine, only single-sided jacquard or double-sided jacquard can be selected for double-sided fabrics, and it is impossible to perform arbitrary conversion of single-sided jacquard or double-sided jacquard without changing the machine. Save equipment resources and improve production efficiency. Due to the small diameter of the needle cylinder of the small circular machine, the double-sided jacquard structure of the traditional large circular machine cannot be installed on the small circular machine. The above-mentioned invention patent does not involve double-sided jacquard of double-sided fabrics The specific structure of the circular knitting machine does not disclose the specific structure of how to realize the arbitrary conversion of single-sided jacquard or double-sided jacquard in the circular weft machine. diameter fabrics, and the circular weft machine with both single-side jacquard and double-side jacquard functions has broad application prospects for producing socks and shoes with various textures; The function of controlling the number of knitting needles when reversing and the needle cylinder is reversing. The motor drives the needle cylinder to rotate in the same direction and can only weave the tube cloth. When it is necessary to produce strips or tubes, it needs to be used Other fabric production equipment or by cutting fabrics, which limits production and processing, and wastes resources, which is not conducive to reducing production costs
