Description

Technical Field

[0001] The utility model relates to the technical field of shuttle looms, in particular to a cloth raising mechanism for shuttle looms. Background Art

[0002] The raising device is a unique mechanism of the towel loom. It makes the wool warp, ground warp and weft yarn interweave to form terry loops to form towel fabrics. Its essence is to control the beating stroke of the steel reed when beating the weft. According to the raising method, the raising device can be divided into two categories: reed-driven type and cloth-driven type. Compared with the reed-driven type, the cloth-driven type has a power mechanism and a raising mechanism. The power mechanism consists of a cam and a connecting rod. The raising principle is that the cam drives the connecting rod to move, and then the connecting rod drives the cloth support beam to swing back and forth, and the length of the connecting rod determines the raising height.

[0003] In the prior art, Chinese patent publication number CN108823762A discloses a cloth-driven raising device and a power mechanism for the cloth-driven raising device, wherein the power mechanism for the cloth-driven raising device includes a servo motor, a crankshaft, a crankshaft connecting rod, a short crankshaft and a mounting frame. The power mechanism for the cloth-driven raising device provided in this solution changes the eccentricity of the crankshaft and the stroke of the crankshaft connecting rod by changing the square reciprocating rotation degree of the servo motor, and then changes the movement stroke of the front and rear positions of the cloth fell by the short crank and the raising mechanism, thereby realizing the change of the raising height, and can realize the adjustment of multiple raising heights. Compared with the method of changing the raising height by replacing the connecting rod in the prior art, the automatic adjustment of the raising height is realized, and the versatility of the power mechanism for the cloth-driven raising device is improved.

[0004] However, when the utility model is actually used, when the short crank drives the raising mechanism to move, the short crank is prone to vibration, which may cause the raising mechanism to have weak stability during operation. At the same time, when the raising work is performed, the warp yarn and the weft yarn are interwoven and rubbed, which easily produces lint fibers, making it inconvenient to remove dust from the lint, so improvement is needed.
