Description

Technical Field

[0001] The utility model relates to the technical field of shuttle looms, in particular to a shuttle guide driving device of a shuttle loom controlled by a roller cam. Background Art

[0002] The shuttle loom is an important machine in the textile industry, used to weave various fabrics, cloths and clothes. The main components of the shuttle loom include the weaving mechanism, the yarn feeding mechanism, the weft releasing mechanism, the driving device, etc. The weaving mechanism includes the frame, the shuttle, the shuttle guide rod, etc. The working principle of the shuttle loom is to use the weaving mechanism to interweave the weft yarn and the warp yarn together to form a fabric. During the working process, the yarn feeding mechanism and the weft releasing mechanism introduce the weft yarn and the warp yarn into the machine and adjust the tension, and then the structure formation and weaving of the fabric are completed through the driving device and the shuttle, and finally the woven fabric is arranged and wound by the cloth winding mechanism.

[0003] In the prior art, for example, the roller cam controlled shuttle loom guide drive device of Chinese patent CN1059722C mainly uses a roller cam to drive the guide wheel on the transmission shaft to drive the transmission shaft to rotate back and forth. The reciprocating stroke of the transmission shaft is controlled by the guide rail on the roller cam. Therefore, when the guide shuttle body changes its movement direction, it can maintain a period of static time to facilitate the beating movement. A planetary gear set is provided at the end of the transmission shaft. The rotation amplitude of the transmission shaft is amplified through the planetary gear set, and the driven shaft drives the pulley to rotate back and forth, thereby driving the guide shuttle body on the magnetically controlled shuttle loom to move back and forth.

[0004] In the above patent, the guide shuttle of the shuttle loom is controlled by a roller cam, and when the guide shuttle body changes its movement direction, it can maintain a period of stillness to facilitate the weft beating movement, which has a good use effect. However, the roller cam drives the guide wheel through the irregular guide rail arranged thereon, and the output power is amplified by the planetary gear set to drive the guide shuttle to reciprocate. During this process, the internal structure of the guide shuttle drive device will vibrate during operation, and the vibration will aggravate the friction of the roller cam on the irregular guide rail, which is easy to affect the service life of the guide shuttle drive device. Therefore, it is necessary to propose a new type of shuttle loom guide shuttle drive device controlled by a roller cam. Utility Model Content
