Shaking table device for computer flat knitting machine

Abstract

The invention relates to a shaking table device for a computer flat knitting machine. The computer flat knitting machine comprises a needle bed body, needle bed connecting guide bars are arranged on the front side and the rear side of the needle bed body, transfer slots are formed in the right ends of the front side and the rear side of the needle bed body, and the shaking table device comprises ashaking table frame arranged on the side, facing downwards, of the needle bed body, a guide bar displacement driving mechanism connected with the needle bed connecting guide bars, a power transmission mechanism which is fixed to the side, facing downwards, of the needle bed body and connected with the guide bar displacement driving mechanism and a zero point and bottom point signal collection mechanism which comprises a zero point signal collector and a sensor chip; the left end of the shaking table is fixed to a left fixing plate of the shaking bed frame, and the right end of the shaking table is fixed to a right fixing plate of the shaking table; the zero point signal collector is fixed to the needle bed body, and the sensor chip is connected with the needle bed connecting guide bars. Cooperation between the shaking table frame and the needle bed body is reliable; connection with the needle bed connecting guide bars is facilitated; daily inspection and protection and operation in the adjusting process are facilitated; an electrical control device accurately control work of the power transmission mechanism.

Description

technical field [0001] The invention belongs to the technical field of computerized flat knitting machines, and in particular relates to a shaker device of a computerized flat knitting machine. Background technique [0002] The computerized flat knitting machine can automatically complete not only the normal loop formation, but also the loop transfer, so that it can knit complex patterns. In order to make the computerized flat knitting machine adapt to the knitting requirements of different fabric structures and patterns (patterns), it is necessary to make the needle bed traverse, and the traverse of the needle bed must be guaranteed by the shaker. Shaker, in addition to its own structure should have sufficient rationality, the traverse speed and positioning accuracy of the needle bed will have an impact on the performance of the computerized flat knitting machine and even the knitting quality of the fabric, for example, when the relative position of the needle bed When mak...

Problems solved by technology

Although the aforementioned patents that are not limited to examples can satisfy the mutual movement between the two needle beds of the computerized flat knitting machine so as to meet the alignment requirements between the transfer needle and the extension needle, there are the following disadvantages: 1. Since the entire shaker assembly is a computerized flat knitting machine structure system, the needle bed body (also called "frame" or "needle bed") is provided with a needle bed (also called "needle board", the same below). Bed", the same below) is set for the carrier, so the reliability of cooperation between the shaker assembly and the needle bed body, the convenience of installation and the convenience of daily maintenance are all important factors that cannot be neglected. However, none of the aforementioned patents gave the necessary technical inspiration; second, as known in the industry, since the motor (usually a servo motor) of the structural system of the shaker assembly needs to be accurately controlled by the electrical controller of the computer knitting flat knitting machine Therefore, it is necessary to determine the zero point and the end point of the structural system of the shaking table assembly and collect and confirm them by the electrical controller. In the aforementioned patent, only CN202865520U introduced the method of determining the zero point and the end point ( 0038 paragraph of the description of this patent), but because the CN202865520U adopts the structure that the long key is driven by the cam, the screw nut is driven by the screw rod and then the needle bed is connected to the guide bar by the needle bed. The structural form in which the bar drives the needle bed to move laterally is not enlightening
