Cloth paving machine, cloth feeding machine and connection mechanism

Abstract

The invention discloses a connection mechanism. The connection mechanism comprises a limiting nut, a lead screw, a bearing and a limiting guide rail, wherein the lead screw is in transmission connection with an output shaft of a rotary driving source and is in threaded connection with the limiting nut, and the rotary driving source can rise and fall synchronously along with a to-be-driven component; an inner ring of the bearing is fixed to the lead screw, and an outer ring of the bearing is fixedly connected with the to-to-driven component; and the limiting guide rail is used for limiting rotation of the limiting nut, and the limiting nut can freely move in the limiting guide rail in the vertical direction so that the lead screw and the output shaft of the rotary driving source can be keptin a pre-bent state. Under any loads, the lead screw and the output shaft of the rotary driving source can be automatically adjusted to the pre-bent state, so that the transmission performance of thedriving source is not affected by load changes, the requirement for the torque of the output shaft of the rotary driving source is lowered, and accordingly, the requirement for the transmission performance of the used driving source is lowered. The invention further discloses a cloth feeding machine adopting the connection mechanism and a cloth paving machine adopting the connection mechanism.

Description

technical field [0001] The invention relates to the technical field of clothing production equipment, in particular to a connection mechanism. In addition, the present invention also relates to a spreading machine and a cloth loading machine comprising the above-mentioned connecting mechanism. Background technique [0002] The existing side-to-side components used for cloth loading machines or spreading machines are driven by linear drive sources. Wherein, the linear driving source is arranged on the outside of the body for carrying the cloth roll, and the side-to-side operation of the cloth roll is realized by pushing the side-to-side parts of the body to move linearly. [0003] For the linear driving source, the fixed end is set on the ground and the driving end is fixed to the opposite side member. When the weight of the cloth roll in the machine body changes, the height of the side-to-side mechanism will fluctuate accordingly, while the height of the fixed end of the l...

AI Technical Summary

Problems solved by technology

When the weight of the cloth roll in the machine body changes, the height of the side-to-side mechanism will fluctuate accordingly, while the height of the fixed end of the linear drive source will not change, so that the driving end of the linear drive source will produce a certain deformation, affecting the straight line. Transmission performance of drive source

In order to ensure the load-carrying capacity of the machine body, the transmission performance of the selected drive source is usually required to be high, which results in a relatively high cost of the drive source.
