Description

Technical Field

[0001] The utility model relates to the technical field of sizing yarn in textile production, in particular to a snap-on sizing shaft with a length scale. Background Art

[0002] It's common knowledge that during the sizing process before weaving in textile production, a certain number of warp yarns on warp beams are combined and then passed through a sizing pot to be soaked in slurry. After sizing, drying, and skeining, the warp yarns are wound onto the sizing beam at the loom's headstock. The distance between the warp yarns' two discs on the sizing beam should correspond to the fabric width during weaving. However, due to the varying widths of fabrics being woven, the left and right discs on the sizing beam must be adjusted according to the width of the fabric. Existing sizing beams consist of a shaft tube, left and right discs, with threads on both ends. One disc has a fixed collar. To adjust the distance between the discs, the operator loosens the set screws on the discs and rotates them to a position consistent with the fabric width. In production practice, due to the high temperature and humidity of the weaving process, the shaft tube accumulates a lot of oil and dust, making the discs inflexible. Furthermore, the spacing between the discs is generally between 1.2 and 2.5 meters, making the adjustment distance relatively long. When adjusting the shaft, the operator must first clean the dirt on the shaft threads, loosen the screws that hold the shaft discs in place, and then use a tape measure to measure the distance between the two discs. After the distance is adjusted, the operator re-measures the dimensions until the process requirements are met. This repeated measurement and adjustment process is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of the invention of the utility model is to provide a snap-on paddle shaft with a length scale. When adjusting the spacing between the disks of the paddle shaft, the distance between the disks can be adjusted conveniently and quickly, and it is firmly fixed without looseness to correspond to different fabric widths and adapt to the needs of different production varieties.

[0004] To achieve the above-mentioned purpose of the invention, the present invention provides a snap-on paddle shaft with a length scale, comprising a shaft core, a paddle shaft left disc, a paddle shaft right disc, and a large gear;

[0005] The right end of the shaft core is fixed with a right disk of the paddle shaft, and the left end of the shaft core is provided with a large gear, and the large gear is connected to the fastening hoop via a fixing screw, and the fastening hoop is fixedly connected to the shaft core;

[0006] Two symmetrical grooves are axially opened on the left end of the surface of the shaft core, and sawtooth-shaped teeth are provided on the inner bottom surface of the groove;

[0007] A left disk of the paddle shaft is further provided between the right disk of the paddle shaft and the large gear. A disk connecting arm is fixed on the left disk of the paddle shaft close to the large gear, and the disk connecting arm can move on the shaft core along with the left disk of the paddle shaft;

[0008] The inner side of the disk connecting arm is axially connected to an adjustment fixing rod via a hinge, the outer end of the adjustment fixing rod is provided with an adjustment clamping head, the adjustment clamping head faces the serrated clamping teeth on the bottom surface of the groove, and the inner end of the adjustment fixing rod is abutted against the inner arc surface of the disk connecting arm via a spring;

[0009] The adjusting screw passes through the screw hole on the disc connecting arm and inserts the adjusting clamp on one end of the adjusting fixing rod into the serrated clamping teeth in the groove to axially fix the left disc of the propeller shaft;

[0010] A scale for measuring the left and right positions of the left disk of the paddle shaft is also provided on the axial surface of the left end of the shaft core.

[0011] Furthermore, the adjusting screw passes through the screw hole on the disc connecting arm via the spring washer to insert the adjusting clamping head at one end of the adjusting fixing rod into the serrated clamping teeth of the groove.

[0012] Furthermore, the shape of the end of the adjusting clamp that contacts the serrated clamping teeth matches the serrated clamping teeth.

[0013] Furthermore, the spring is a compression spring.

[0014] Furthermore, the adjusting and fixing rod is located above the groove, and the adjusting and fixing rod is axially parallel to the groove on the surface of the shaft core.

[0015] Furthermore, the starting point of the scale is one meter away from the inner side of the right disc of the paddle shaft, and the end point extends to the left to the fastening hoop. The minimum measurement unit of the scale is 0.5 cm.

[0016] Furthermore, the grooves on the shaft core are symmetrically arranged up and down.

[0017] Furthermore, the fastening hoop is fixedly connected to the shaft core keyway.

[0018] Compared with the prior art, the present invention designs a length scale on the paddle shaft, the minimum unit of which is 0.5 cm, and the length range is 70 cm-170 cm. Two symmetrical grooves are designed on the shaft core, and there are serrated teeth at the bottom of the grooves. The adjusting screw on the connecting arm of the left disk of the paddle shaft can adjust the distance between the adjusting clamp and the serrated teeth. The operator loosens the adjusting screw, adjusts the spring at the other end of the fixing rod to retract, and the adjusting clamp is disengaged from the serrated teeth. The left disk of the paddle shaft is adjusted to the distance required by the process. The operator tightens the fixing screw with a wrench so that the adjusting clamp is stuck with the serrated teeth, and the left disk of the paddle shaft is locked and fixed. In the process of adjusting the spacing between the two disks of the paddle shaft to the process requirements, the operator does not need to use a tape measure to measure. The length scale on the shaft core can directly reflect the spacing between the two disks. Through the cooperation of the two adjusting screws, the adjusting clamp, and the serrated teeth, the left disk of the paddle shaft can be easily and simply adjusted to move left and right and fixed. The operation is simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS
