Needle plates on two sides of the glove knitting machine are arranged in a herringbone mode, and a sinker seat is arranged at the top of the needle plates, so that sinkers and knitting needles work in a knitting area to form a loop. The existing sinkers are all in straight-line long strips, the sinkers on two sides are arranged in an inverted herringbone mode to correspond to a needle plate and a knitting needle, two sets of sinker cams can only be located between the included angles of the sinkers on two sides, the included angles of the sinkers on two sides need large installation space of the sinker cams, and therefore the space occupied by a knitting line pressing mechanism consisting of the sinkers and the sinker cams is large. The sinker is in direct-insert motion and is easy to collide with the knitting needle. The sinker is in high-speed linear motion in the sinker chute of the sinker seat, the impact force is large, and large noise is easy to generate.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems that the existing knitting and stitching mechanism of the glove machine occupies a large space and a sinker is easy to generate large noise in the sliding process, the utility model aims to provide the knitting and stitching mechanism of the glove machine, which can reduce the occupied space, operate stably and generate small noise.
Therefore, the utility model adopts the following technical scheme: a knitting and thread-pressing mechanism of a glove knitting machine comprises a sinker cam, a sinker seat and a plurality of sinkers, wherein a driving guide groove is formed at the bottom of the sinker cam, and the knitting and thread-pressing mechanism is characterized in that each sinker comprises a sliding guide section and a thread-pressing section, the bottom side of the sliding guide section forms an arc-shaped cylindrical surface, a driving piece butt is formed at the top side of the sliding guide section, a plurality of sinker sliding grooves for accommodating the sinkers are arranged on the sinker seat in an arrayed mode, the sinkers are slidably installed in the sinker sliding grooves, the bottom surfaces of the sinker sliding grooves are correspondingly matched with the bottom sides of the sinkers to form the arc-shaped cylindrical surfaces, the sliding of the sinkers in the sinker sliding grooves is supported and guided, and the driving piece butts extend out of the sinker sliding grooves and are embedded in the driving guide groove at the bottom of the sinker cam; the sinker cam is fixedly connected with a reciprocating transverse machine head on the glove machine, reciprocates transversely along with the machine head, and drives a driving plate heel on the sinker through the wall of the driving guide groove so as to drive the sinker to slide in the sinker chute.
In addition to the above technical solutions, the present invention also includes the following technical features.
The top sides of the sinkers form arc-shaped cylindrical surfaces, limiting grooves penetrating all the sinker sliding grooves are formed in the tops of the sinker seats, and limiting parts are arranged in the limiting grooves, so that the sinkers are limited by the limiting pieces to slide in the sinker sliding grooves in an arc shape.
The top of the sinker seat is provided with two limiting grooves which traverse all sinker sliding grooves, the two limiting grooves are arranged at intervals in the sliding direction of the driving lug heels, and the driving lug heels are positioned between the two limiting grooves, so that the position and the sliding stroke of the sinker are more stably limited.
The bottom sides of the pressing section and the sliding guide section of the sinker form a step, and the bottom side of the pressing section of the sinker is spaced from the bottom surface of the sinker sliding groove by a certain distance, so that high-speed friction heating and noise generated by the contact of the pressing part and the sinker sliding groove are avoided, and the moving abdication of the insert and the fork cutter is realized.
The utility model can achieve the following beneficial effects: according to the utility model, the bottom sides of the sinkers and the bottom surfaces of the sinker sliding grooves of the sinker seats are arranged into the arc-shaped cylindrical surfaces which are mutually matched, and the sinkers do arc-shaped sliding motion when pressing yarn coils, so that the impact generated by the linear motion of the traditional sinkers is avoided, the operation is more stable, the high-speed friction heating is reduced, and the noise is reduced; the top sides of the sinkers are also designed into arc shapes, so that the sinker cams can be arranged on the top sides of the sinker seats, the limitation that the sinker cams can only be positioned in a limited space between the sinker included angles on two sides is eliminated, the included angles of the needle plates on two sides can be set according to the requirement of occupying smaller space, and the occupied space of equipment is reduced; the adoption sinker arc orbit makes the braided coil more even, and does not have the interference risk with going upward colluding sword, and installation adjustment is convenient.
