Description

Technical Field

[0001] This utility model relates to a double tension spring transverse movement structure and a warp knitting machine, belonging to the field of transverse movement structures for warp knitting machines. Background Technology

[0002] The lateral movement structure of a warp knitting machine is a part of the machine and is mainly used to control the lateral movement of the guide needles during the knitting process to achieve different knitting patterns and structures. The lateral movement structure consists of a comb structure with guide needles installed, a lateral movement drive mechanism, etc.

[0003] Traditional mechanical transverse movement structures use tension springs as the reset device, which has the following drawbacks: the vibration frequency of the tension spring is close to that of the transverse movement motor, causing resonance; under long-term high-frequency movement, the tension spring is prone to metal fatigue, resulting in a decrease in the elastic coefficient or even breakage, requiring frequent replacement; and when running at high speed, the reset speed of the tension spring cannot match the rapid start and stop of the comb, which may lead to reset delay, causing comb vibration or positioning deviation.

[0004] Therefore, this utility model provides a double tension spring transverse structure with high load-bearing capacity and a warp knitting machine. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a double tension spring transverse structure with high load-bearing capacity and a warp knitting machine.

There are two comb reset mechanisms and hooks, which are respectively installed at the upper and lower ends of the transverse shift seat and the hanging bracket pressure plate. The comb reset mechanisms and hooks with corresponding positions are connected and fixed by the tension springs.

[0013] One end of the second rotating component is threaded onto the transverse sliding seat, and the other end is connected to the end of the first rotating component on which a washer is installed.

[0014] As a further improvement, the end of the second rotating member that contacts the first rotating member is hemispherical.

[0015] As a further improvement, the number of the hanger pressure plate and the transverse sliding seat is one or more sets.
