Description

Technical Field

[0001] The utility model relates to the technical field of spinning, in particular to an upper shaft mechanism of a jet loom. Background Art

[0002] A jet loom is a weaving machine that uses high-pressure gas (usually air) to inject weft yarn into the warp. Its efficiency and speed play a vital role in the modern textile industry. Modern jet loom technology typically incorporates nozzle technology, electronic controls, automation features, and a weft supply system. These technologies work together to ensure accurate and even insertion of the weft yarn into the warp, thereby improving fabric quality and production efficiency.

[0003] After completing the production of a single fabric, the warp yarn shafts need to be replaced to continue production. While existing shaft-changing devices can achieve automated shaft-changing, they are often complex or laborious to operate. These issues often result in a lengthy shaft-changing process, reducing overall production efficiency. Utility Model Content

[0007] The technical principle of the utility model is: when the warp shaft needs to be installed, the lifting hydraulic mechanism is lowered to the lowest point, and then the warp shaft is placed on the semicircular arc bearing. Then the lifting hydraulic mechanism drives the semicircular arc bearing to support the warp shaft and lift it. When it is lifted to the clamping drive mechanism, the clamping drive mechanism clamps the warp shaft. At this time, the semicircular arc bearing plays an auxiliary supporting role.

[0011] Furthermore, the lifting hydraulic mechanism also includes two telescopic rods, which are symmetrically arranged on both sides of the hydraulic cylinder. The telescopic rods are arranged on the bottom plate at an angle to each other, and the tops of the telescopic rods are connected to semicircular arc bearings.

[0012] Furthermore, the semicircular arc bearing includes an arc ring and an arc retainer, the arc retainer is fixed on the arc ring, cavities are evenly distributed on the retainer, rollers are arranged in the cavities, the cylindrical surfaces of the rollers are close to the arc ring, and the diameter of the rollers is greater than the width of the arc retainer.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figure 1-2 The upper shaft mechanism of the jet loom shown in the figure is provided with a shaft mounting notch 110 on the jet loom 100, and a clamping drive mechanism is provided on both sides of the shaft mounting notch 110. The specific clamping drive mechanism includes a drive motor 120 and an electric push rod 130, wherein the electric push rod 130 and the drive motor 120 are respectively arranged on both sides of the shaft mounting notch 110, the rotating shaft of the drive motor 120 is connected to the drive block 121, and the electric push rod 130 is connected to the bearing 131. The positions of the bearing 131 and the drive block 121 are symmetrical to each other, and the bearing 131 and the drive block 121 are both provided with an annular The protrusion 132, then it is only necessary to raise the warp shaft to the horizontal height position of the bearing 131 and the drive block 121, and then let the electric push rod 130 push the warp shaft, so that the warp shaft is stuck in the annular protrusion 132 of the bearing 131 and the drive block 121 to achieve coaxial positioning. Because the electric push rod 130 is in the pushed-out state, the warp shaft is pressed against the drive block 121. When the drive motor 120 drives the drive block 121, the warp shaft will rotate synchronously due to friction, and the bearing 131 of the electric push rod 130 ensures that the electric push rod 130 will not rotate with the warp shaft.

[0026] Specifically, a speed reducer is provided between the driving motor 120 and the driving block 121 for slowing down the rotation speed of the driving motor 120 .

[0027] The bearing 131 and the driving block 121 are both provided with a support seat 122 to play a supporting role.

[0028] like Figure 2-3 As shown, two symmetrically arranged upper shaft mechanisms 200 are provided at the shaft mounting notch 110, and the two upper shaft mechanisms 200 are respectively arranged near both sides of the shaft mounting notch 110; the specific upper shaft mechanism 200 includes a semi-circular arc bearing 210 and a lifting hydraulic mechanism 220 connected to the lower side of the semi-circular arc bearing 210, and the lifting hydraulic mechanism 220 can drive the semi-circular arc bearing 210 to move in the vertical direction. A common bottom plate 230 is provided at the bottom of the two lifting hydraulic mechanisms 220, which realizes the lifting and lowering of the warp shaft.

[0029] like Figure 3 As shown, the lifting hydraulic mechanism 220 includes a hydraulic cylinder 221 vertically arranged on the base plate 230. The top of the piston rod of the hydraulic cylinder 221 is connected to the semicircular arc bearing 210 and needs to be driven by a hydraulic pump. It can provide stable lifting force to support the warp shaft.

[0030] like Figure 3 As shown, the lifting hydraulic mechanism 220 also includes two telescopic rods 222, which are symmetrically hinged on both sides of the hydraulic cylinder 221. The telescopic rods 222 are arranged on the base plate 230 at an angle to each other, and the tops of the telescopic rods 222 are hingedly connected to the semicircular arc bearings 210 to form a stable triangle to prevent the lifting hydraulic mechanism 220 from falling sideways.

[0031] like Figure 3-4 As shown, the semicircular arc bearing 210 includes an arc ring 211 and an arc retainer 212, wherein the arc retainer 212 is fixed on the arc ring 211, and cavities are evenly distributed on the retainer. Rollers 213 are arranged in the cavities, and the cylindrical surfaces of the rollers 213 are tightly attached to the arc ring 211. The diameter of the rollers 213 is larger than the width of the arc retainer 212 and can directly contact the warp shaft.

[0032] Example 2

[0033] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that an infrared detector 231 is provided in the middle of the bottom plate 230 for detecting the condition of the warp shaft and cooperating with the control system to control the operation of the jet loom 100.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
