Description

Technical Field

[0001] This utility model belongs to the field of machine testing technology, and specifically relates to a machine testing device. Background Technology

[0002] During operation, the loom requires constant monitoring of the warp beam's working status, specifically the state where the warp yarns on the beams are depleted. Even with the accurate warp yarn length entered into the loom's electrical control system display during warp beam replacement, accumulated errors due to continuous adjustments in the weaving process and other human factors can compromise the timeliness of warp yarn replacement. This necessitates pre-replacement, resulting in wasted warp yarns and requiring personnel to continuously inspect the remaining warp yarns on the looms throughout the production workshop. This leads to high labor intensity and a low level of automation in the workshop. Utility Model Content

Several pay-off devices are connected to the loom frame and used to fix the yarn spool. Two slide bars are connected to the loom frame and slidably connected to the sliding guide device. Several sensors are installed on the loom frame and cooperate with the sliding guide device. The sliding guide device includes a carriage, linear bearings, tension rollers, and a tension adjusting device. Two linear bearings are connected to the carriage and slidably connected to two slide bars respectively. Two tension rollers are symmetrically and movably connected to the carriage, and their rotation speed is controlled by the tension adjusting device.

[0005] Preferably, the tension adjusting device includes a bolt, a spring, and a damping block. The slide has a screw hole for the bolt, spring, and damping block to enter, and the damping block in the screw hole is in contact with one end of the tension roller.

Detailed Implementation

[0021] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figure 1 As shown; a loom detection device includes a loom frame 1, a pay-off device 2, a slide bar 3, a sensor 4, a sliding guide device 5, and a yarn spool. Several pay-off devices 2 are connected to the loom frame 1 and used to fix the yarn spool. Two slide bars 3 are connected to the loom frame 1 and slidably connected to the sliding guide device 5. Several sensors 4 are installed on the loom frame 1 and cooperate with the sliding guide device 5. The sliding guide device 5 includes a slide frame 51, linear bearings 52, tension rollers 54, and a tension adjusting device 55. Two linear bearings 52 are connected to the slide frame 51 and slidably connected to two slide bars 3 respectively. Two tension rollers 54 are symmetrically and movably connected to the slide frame 51 and their rotation speed is controlled by the tension adjusting device 55. The tension adjusting device 55 includes... Bolts, springs, and damping blocks are provided. The slide 51 has screw holes for the bolts, springs, and damping blocks to enter. The damping blocks in the screw holes are in contact with one end of the tension roller 54. One tension roller 54 has two spinning limit rings 56, and the other tension roller 54 has a groove for the spinning limit rings 56 to enter. A traction plate 53 is connected to the slide 51, and a traction hole 57 is provided on the traction plate 53. Several limit plates 6 are evenly arranged on the slide rod 3. The yarn feeding device 2 includes a yarn feeding tube 21, and several clamping plate slots 22 are provided on the yarn feeding tube 21 at the same horizontal line. Clamping plates 23 are hinged in the clamping plate slots 22, and torsion springs are connected to the hinges of the clamping plates 23. An alarm light is provided on the loom frame 1 on one side of the yarn feeding device 2.

[0024] The warp yarn spool is inserted into the pay-off tube 21 and secured inside by the clamping plate 23 to prevent rotation. The warp yarn is then pulled through the traction hole 57 and between the two symmetrical tension rollers 54, and then drawn into the loom. Specifically, two pay-off devices 2 can be used as a group, or multiple devices can be set as needed. The outer end of the warp yarn on the spool is connected to the inner end of the warp yarn on the adjacent pay-off device 2, so that when the warp yarn on one spool is used up, the next one can be directly connected. During this switching process, the warp yarn becomes taut due to continuous output. The taut warp yarn will cause the linear bearing 52 of the tension adjustment device 55 to slide on the slide rod 3. The tension adjustment device 55 moves until it slides above the yarn reel, so that the warp yarn is vertically led out. This is detected by the sensor 4 when the tension adjustment device 55 moves, at which point the alarm light illuminates, so as to achieve the purpose of timely replacement of the yarn reel. The position of the warp yarn is restricted by the two yarn limiting rings 56 to prevent the warp yarn from being pulled out of the working range of the tension roller 54. By rotating the bolt, the bolt pushes the spring, and the spring pushes the damping block to apply friction to one end of the tension roller 54, so as to control the rotation speed of the tension roller 54 and achieve the purpose of controlling the warp yarn tension. The clamping plate 23 unfolds by the torsion spring, and then the unfolded clamping plate 23 clamps the yarn feeding tube 21 to prevent the yarn feeding tube 21 from rotating when leading out the warp yarn.
