Description

Technical Field

[0001] This utility model relates to a mechanism, and more particularly to a linear sliding mechanism for the blades of the spreading wheel of a fabric spreading machine, which belongs to the technical field of fabric spreading machine equipment. Background Technology

[0002] A fabric spreading machine (also known as a fabric laying machine) can lay rolls of fabric flat on a machine table, and then use other tools to further process the flat fabric. However, due to the softness of some fabrics, especially knitted fabrics, which are elastic, when the fabric is stretched to a certain length, its elastic recovery force often causes many wrinkles, making the stretched fabric unable to be laid flat on the cutting bed. This requires workers to sort it, increasing the labor intensity of workers, reducing work efficiency, and causing trouble for subsequent processes. To solve this problem, a fabric spreading wheel structure is usually set on the fabric spreading machine. The fabric spreading wheel structure generally consists of a lifting wall, a cam, a rotating shaft, blades, and blade contacts. Its working principle is as follows: The rotating shaft is rotatably connected between two lifting walls. The blades are set on the outer circumference of the rotating shaft. The blades are engaged in the annular groove of the cam through the blade contacts. The rotating shaft drives the blades to rotate circumferentially, and at the same time, the different curvatures of the annular grooves drive the blades to move linearly left and right on the rotating shaft.

[0003] Chinese patent CN205257630U, published on May 25, 2016, discloses a utility model patent entitled "Sliding Rod Type Spreading Roller Mechanism." This patent includes spreading rollers mounted on two lifting walls. Several pairs of long blades are circumferentially spaced on the outer wall of the spreading rollers. The axes of each pair of long blades overlap and are symmetrically slidably mounted on both sides of the spreading roller. Cams are fitted on the roller shafts at both ends of the spreading rollers. One end of the cam is fixed to the lifting wall and has an annular groove. Each long blade has a guide shaft at its outer end, and a bearing is fitted at the lower end of the guide shaft. The bearing is located in the annular groove and contacts the two side walls of the annular groove. The rotation of the spreading roller drives the long blades to rotate circumferentially, while the long blades are restricted by the trajectory of the annular groove to perform axial reciprocating motion. Although this patent can reduce the power loss and wear of the sliding rod and pulley and extend the service life of the sliding rod and pulley, it is structurally different from this patent and cannot achieve the effect of this application patent.

The end of the spreading wheel shaft is also provided with a spreading wheel connecting wheel and a spreading wheel cam. The spreading wheel connecting wheel is equipped with a pawl wheel, and the spreading wheel cam is axially arranged on the spreading wheel connecting wheel. Its key feature is… The features include: it also includes a spreading wheel aluminum tube and multiple sets of spreading wheel blades. The spreading wheel fixing ring is surrounded by a spreading wheel aluminum tube, which can drive the spreading wheel to rotate around the spreading wheel axis. Several sets of spreading wheel blades are distributed along the circumference of the spreading wheel aluminum tube on the outer circumference surface of the spreading wheel aluminum tube. The spreading wheel blades are long and strip-shaped and are arranged along the axial direction of the spreading wheel aluminum tube. A swing wheel that can rotate around the spreading wheel cam is provided on the spreading wheel cam. The spreading wheel blades are connected to it in a linear sliding connection structure.

[0006] Preferably, the present invention also includes connecting bolts and self-lubricating sliders. The connecting structure includes an axial groove on the claw wheel, a spreading wheel cam slidably connected in the groove, and a plurality of connecting bolts and self-lubricating sliders between the outer side of the swing wheel and the axial groove on the claw wheel.

[0007] Preferably, the aluminum tube of the spreading wheel described in this utility model has several strip grooves on its circumference along the axial direction of the aluminum tube, and the self-lubricating slider is located in several strip grooves along the axial direction of the aluminum tube.

[0008] Preferably, the cross-sectional profile of several strip-shaped grooves along the axial direction of the aluminum tube of the spreading wheel in this utility model is a gourd-shaped through-slot, through which the self-lubricating slider passes. The gourd-shaped through-slot has a large hole to facilitate the installation and adjustment of the self-lubricating slider.

[0009] Preferably, each set of spreading wheel blades in this invention includes two blades, which are respectively close to both ends of the spreading wheel shaft. The two spreading wheel blades are spaced apart and located on the same straight line.

[0010] Preferably, the aluminum tube of the spreading wheel of this utility model is cylindrical, and the spreading wheel connecting wheel and spreading wheel cam are sleeved on the spreading wheel shaft and close to the end of the spreading wheel shaft. The outer circumferential surface of the spreading wheel aluminum tube is provided with a gourd-shaped through groove, and each spreading wheel blade is fixed with a guide shaft along the radial direction of the spreading wheel shaft. The outer end of the guide shaft is inserted into the swing wheel.

[0011] Compared with the prior art, this utility model has the following advantages and effects: the overall structure is reasonably designed and safe and reliable. By connecting the blade to the slider and setting the self-lubricating slider on the aluminum tube of the spreading wheel, the friction coefficient between the blade and the aluminum tube of the spreading wheel is greatly reduced when the blade moves linearly, thereby greatly reducing the friction and wear. At the same time, the blade vibration is small, the noise is low, the structure is stable, and it can achieve stable operation of spreading for a long time. Attached Figure Description

The spreading wheel shaft 1 has a spreading wheel fixing ring 2 on its inner ring, which can move in a circle around the spreading wheel shaft 1. The spreading wheel fixing ring 2 is surrounded by a spreading wheel aluminum tube 3, which can drive the spreading wheel fixing ring 2 to rotate in a circle around the spreading wheel shaft 1. Several sets of spreading wheel blades 4 are distributed along the circumference of the spreading wheel aluminum tube 3 on its outer circumferential surface. The spreading wheel blades 4 are long strips and are arranged along the axial direction of the spreading wheel aluminum tube 3.
