Abstract

A jacquard cam of a seamless underwear machine belongs to the technical field of seamless underwear, comprises a middle cam, a needle dividing cam and a needle lowering cam and is characterized in that the needle lowering cam and the middle cam are provided with piston rods pushed by a combined cylinder, so that the needle cam and the middle cam can conduct complete or incomplete driving actions in the radial direction; and the middle cam has a needle throwing track and a needle lowering at the same time. According to the invention, the needle dividing and the needle lowering functions of a needle lowering cam in the prior art are separated, the independent needle dividing cam and the independent needle lowering can are designed, and meanwhile a middle auxiliary cam and a jacquard clearing cam are eliminated, so that the distance between the needle throwing track of the middle cam and the needle guiding groove of the needle dividing cam is reduced, and a middle piece and a knitting needle can be supported effectively under any conditions; and when special patterns are woven, the middle cam and the needle lowering cam can respectively realize complete or incomplete driving and withdrawing actions, so as to weave the special patterns with a high quality.

Description

The seamless underwear machine accordion cam

Technical field

The invention belongs to the seamless underwear machine technical field, be specifically related to a kind of seamless underwear machine accordion cam.

Background technology

Existing seamless underwear machine accordion cam, it falls the pin triangle and is fixed on the mount pad, and it plays minute hand simultaneously and falls the pin function; In the common colored type of braiding when organizing, fall the pin triangle and be fixed on the mount pad and can satisfy the braid movement requirement, but in reality braiding processing; Weave some special colored type tissues; Falling the pin triangle is fixed on the mount pad and just following problem has occurred: because the fixing pin that falls does not possess the function of squeezing into and withdrawing from, weave special colored type tissue, and must adding jacquard weave needle clearing cam; Distance increases between the pin triangle minute hand position apart from falling yet the adding of jacquard weave needle clearing cam causes the ultra pin track of middle triangle; Reach 40.3～42.5mm, in the braiding process, knitting needle all loads in this segment distance must all be accumulated on the middle triangle through intermediate; For the stability that guarantees to weave, must, jacquard weave needle clearing cam front come knitting needle is effectively supported by auxiliary triangle in the middle of adding.So existing accordion cam mechanism, its middle triangle will be by an independently single cylinder control, and middle auxiliary triangle and jacquard weave needle clearing cam are controlled by a Composite cylinder; Falling the pin triangle is fixed on the mount pad; Therefore structure is too complicated, and the parts of doing relative motion with knitting needle are many, and the fluency of process intermediate, knitting needle motion is poor; Knitting needle is fragile, influences the quality of fabric jacquard weave simultaneously; In addition, because structure is too complicated, the manufacturing cost of said mechanism is high.

Summary of the invention

The objective of the invention is to provide a kind of seamless underwear machine accordion cam; Through to existing seamless underwear machine middle triangle, minute hand triangle, the improvement of the above-mentioned major defect that exists on the pin three-legged structure is fallen; When satisfying special colored type tissue braiding, realize simplifying mechanical structure, reduce manufacturing cost, reduce the knitting needle loss, improve the purpose of fabric jacquard weave quality.

The foregoing invention purpose is achieved through following technical scheme; A kind of seamless underwear machine accordion cam; Comprise middle triangle, the pin triangle falls in the minute hand triangle; Its main points are: fall pin triangle, middle triangle and be provided with the piston rod that promoted by combined cylinders, make and fall that pin trigonometric sum middle triangle can be done radially full position, subluxation is squeezed into action; Middle triangle has ultra pin track simultaneously and falls the pin track.

Above-mentioned seamless underwear machine accordion cam, the ultra pin track of one of its structure middle triangle is 7～9mm apart from the distance of minute hand triangle guide pin slot.

The present invention with the minute hand that falls the pin triangle of the prior art with fall the pin function and be divided into two; Being designed to independently, the pin triangle falls in the minute hand trigonometric sum; Got rid of middle auxiliary triangle of the prior art, jacquard weave needle clearing cam simultaneously, thereby can reduce the distance between ultra pin track of middle triangle and the minute hand triangle guide pin slot, made the optimal spacing that remains between the two between 7～9mm; Make intermediate and knitting needle under any situation; Can both obtain middle triangle, the minute hand triangle effectively supports, and can form a stable trajectory all the time, protection knitting needle safety gets into the guide pin slot of minute hand triangle; When some special colored types of braiding are organized; Because its minute hand triangle is installed in combined cylinders top; Be in stationary state, the piston rod of middle triangle is installed on two pistons of combined cylinders with the piston rod that falls the pin triangle, can realize full position respectively, subluxation is squeezed into and withdraw from action; So under the situation of having got rid of the jacquard weave needle clearing cam, still can knit out special colored type tissue by high-quality; In addition, simplify the existing machinery structure, reduced the manufacturing cost of seamless underwear machine.
