Jacquard ribbon loom with mainstay

Abstract

A jacquard ribbon loom with a central column, comprises a hollow central column over the machine platform, the main driving belt in the central column, a spigot and a power transmission member on the top end of the central column, weft transmission member symmetrically on the two sides of the central column. The light jacquard ribbon loom is compact and stable due to the hollow central column.

Description

(1) Technical field [0001] The invention relates to a jacquard weaving machine, in particular to a frameless jacquard weaving machine. (2) Background technology [0002] Jacquard ribbon looms have been developed for quite a long time. The existing jacquard ribbon looms of various brands are equipped with a ㄇ-shaped outer frame on the machine table, and a faucet is erected on the top of the outer frame. The weft yarn transmission device is assembled by erecting a horizontal shaft between them. Analyzing the basic concept of its outer frame setting, it can be seen that it mainly frees up the space above the machine table for the installation of the weft yarn transmission device, so the bracket for erecting the rotating shaft of the weft yarn transmission device is set in The two sides above the machine table; in order to install the faucet above to control the jacquard and provide the appropriate support force for the faucet, a wide plate-shaped bracket design or a design with...

AI Technical Summary

Problems solved by technology

[0005] 1. The transmission mechanism is complicated: because the power transmission path must be connected to the ㄇ-shaped outer frame structure, the power stroke is extended, which increases the loss in the power transmission process, resulting in waste of power and energy; because of its matching transmission mechanism The high complexity makes the production cost unable to be reduced; the complexity of the transmission mechanism increases the difficulty of maintenance; the long transmission path makes it easy to cause poor stability in the operation of various parts of the jacquard belt machine, which requires extremely high synchronization As long as there is an error in any part of the machine, it may affect the effect of the overall operation

[0006] 2. Inconvenient operation: limited by the setting of the brackets on both sides of the outer frame, the weft yarn transmission device is sandwiched between the two brackets, which will inevitably affect the convenience of operation, because the jacquard loom must be operated by the operator. The weft yarns are threaded on the weft yarn transmission device one by one. The two brackets of the existing ㄇ-shaped outer frame just block the operator's sight and operation path, which causes considerable inconvenience to the operator; When threading the weft yarn, one side must pass over the belt or related power transmission mechanism of the transmission mechanism on one side of the support, which will cause safety concerns

[0007] 3. It is not easy to replace parts after wear and tear: Since the existing weft yarn transmission device is sandwiched between the two sides of the outer frame, if it is to be replaced, the rotating shaft must be pulled out from between the two supports, that is, each group of weft yarn transmission devices must be pulled out. Unloading at the same time, its replacement procedures are complicated, and it is quite inconvenient to install and adjust

[0008] From the above description, it can be known that the existing jacquard looms using the ㄇ-shaped outer frame cannot provide an ideal operating environment in actual operation, and the structural arrangement is not perfect.
