Abstract
An auxiliary knocking-over device of a flat knitting machine comprises a lifting mechanism and a presser foot device. The lifting mechanism is connected with a machine head of the flat knitting machine, the presser foot device is driven to vertically move between a work position and a standby position by the lifting mechanism, a press rod extending along the length direction of the flat knitting machine is arranged in front of the presser foot device, when the presser foot device is located at the work position, the press rod is located at a position close to the back of a knitting needle, and yarn loops are pressed relative to the rising knitting needle so as to realize auxiliary knocking over. The auxiliary knocking-over device can accurately assist the knitting needle to complete knocking-over actions, thereby guaranteeing weaving quality of the flat knitting machine.
Description
Technical field
The utility model relates to a kind of auxiliary knocking over device of flat machine.
Background technology
Flat machine is in knitting needle is made elevating movement process clocklike, realize yarn the pad yarn, remain silent, actions such as lasso, kinking, knocking over and lopping, thereby finish the braiding of cloth.When knitting needle in the ascending motion process because the friction of the relative coil of knitting needle bar and the elasticity of yarn, coil can upwards float with knitting needle, thereby influences carrying out smoothly of lopping.For this reason, flat machine is provided with roller and sinker device and finishes knocking-over action smoothly with auxiliary knitting needle.In the knitting needle uphill process, roller draws fabric downwards, sinker colludes and holds coil, stops coil to rise, thereby reaches the purpose of knocking over.
But existing roller and not useful effect of sinker device are in the braiding of all flower type tissues.As weaving the tissue that suddenly increases coil, roller and sinker are assisted and are occurred failing effective tractive coil in the knocking over process easily, thereby it is unclean knocking over to occur, causes the braiding mistake.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of auxiliary knocking over device is provided, and this device can assist knitting needle to finish knocking-over action like clockwork.
For this reason, the auxiliary knocking over device of a kind of flat machine that the utility model provides, it is characterized in that: comprise the elevating mechanism that is connected with flat-knitting machine head, drive the foot device of lifting moving between operating position and position of readiness by elevating mechanism, described foot device front side has the depression bar that extends along the straight-bar machines length direction, when foot device is in the operating position, described depression bar is positioned at the position near the knitting needle needle back, and the knitting needle that rises is relatively pushed coil with auxiliary knocking over.
Further, described elevating mechanism, comprise the holder of fixedlying connected with flat-knitting machine head, and be movably connected on the holder and make the portable plate of lifting moving by motor-driven, be provided with a swing arm between described portable plate and the holder, the swing arm two ends are connected with portable plate with holder by pivotal pin respectively, described holder is provided with pilot hole, be set with the guide post that laterally is arranged in the pilot hole on the described portable plate, described motor output shaft is provided with a cam, be provided with a connecting rod between cam and the swing arm, the connecting rod two ends are connected with swing arm with cam by pivotal pin respectively, and described foot device is connected described portable plate front end.
Further, above-mentioned elevating mechanism also comprises the spring that is tensioned between the pivotal pin of described connecting rod two ends, and described connecting rod is connected with swing arm with corresponding pivotal pin by elongated hole.
Further, described pilot hole is an arcuate socket.
The utlity model has following beneficial effect:
During work, the depression bar of foot device can move around between near the position of knitting needle needle back and the position away from knitting needle, and the knitting needle that rises is relatively pushed coil with auxiliary knocking over.The utility model has overcome that some particular tissues Yin Luola and sinker can't effectively assist problems such as knocking in the prior art, can assist knitting needle to finish knocking-over action exactly, thereby effectively improve the weaving quality of flat machine; Setting is tensioned to the spring between the pivotal pin of connecting rod two ends, and connecting rod is connected with swing arm with corresponding pivotal pin by elongated hole, when withstanding solenoid force, depression bar spends when big, can cushion by elongated hole and spring, strength is softer, prevents to damage coil, the pilot hole of motion is set to arcuate socket, the depression bar of foot device is moved along certain arching trajectory, can prevent depression bar in course of action with miscellaneous part mutual interference mutually, thereby effectively guarantee the precision maneuver of depression bar.
