Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and in particular to a warping beam limiting structure. Background Technology

[0002] In the warping process of textile machinery, the warp beam needs to be stably mounted on the main shaft and driven by transmission gears to rotate for yarn winding or unwinding. Traditional warp beam structures often use rigid retaining rings, snap rings, or screws for direct axial locking of the warp beam. However, these methods have obvious drawbacks: rigid retaining rings and snap rings are prone to axial movement or even loosening of the warp beam due to small gaps when the main shaft is running at high speed or the yarn tension fluctuates, causing problems such as yarn deviation, yarn breakage, and yarn tangling, which seriously affect the warping quality and efficiency; while screw locking can secure the warp beam, it is inconvenient to disassemble and replace the warp beam, the operation is cumbersome and time-consuming, and repeated tightening can easily cause thread wear or stripping, reducing structural reliability. Utility Model Content

[0005] In some embodiments, the elastic element is a flexible metal bend rod, the middle of which forms the limiting portion that protrudes outward from the receiving groove.

[0006] In some embodiments, a screw hole is provided at the bottom of the receiving groove, and a fixing ring or fixing lug is provided at one end of the elastic element. A bolt passes through the fixing ring or fixing lug and is screwed into the screw hole to fix the elastic element in the receiving groove.

[0007] In some embodiments, after the bolt is tightened, its head is recessed or flush with the opening plane of the receiving groove, and not higher than the receiving groove.

[0008] In some embodiments, the limiting portion has a first guide slope on the side facing the transmission gear and a second guide slope on the side facing away from the transmission gear, wherein the inclination angle of the first guide slope relative to the main shaft axis is greater than the inclination angle of the second guide slope.

[0009] In some embodiments, a plurality of positioning pins are protruding on one end face of the transmission gear facing the warp cylinder, and a positioning hole is opened on the end face of the warp cylinder near the transmission gear corresponding to the positioning pins. The positioning pins are inserted into the positioning holes to achieve circumferential positioning of the transmission gear and the warp cylinder.

[0010] In some embodiments, the receiving groove is a rectangular groove, an arc-shaped groove, or a circular groove.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] This application continuously applies an elastic preload force toward the transmission gear to the bearing through the limiting part of the elastic element, which can automatically compensate for the small gaps caused by manufacturing tolerances, bearing wear or vibration, and ensure that the warp roller maintains a stable axial position when running at high speed and when the yarn tension changes.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] refer to Figures 1 to 5This application provides a warping beam limiting structure, comprising: a main shaft 1, a transmission gear 2 fixedly connected to one side of the main shaft 1, a warp beam cylinder 3 rotatably sleeved on the main shaft 1, bearings 4 respectively provided on both sides of the warp beam cylinder 3, an axially formed receiving groove 5 on the side of the main shaft 1 near the transmission gear 2, an elastic element 6 provided in the receiving groove 5, the elastic element 6 having an elastically deformable limiting part 7, the limiting part 7 protruding from the opening plane of the receiving groove 5 in its natural state; wherein, the bearing 4 near the transmission gear 2 is disposed between the transmission gear 2 and the limiting part 7 of the elastic element 6, the elastic element 6 applying an elastic preload towards the transmission gear 2 to the bearing 4 through its limiting part 7, thereby limiting the axial movement and detachment of the warp beam cylinder 3 during the yarn unwinding process.

[0020] In some embodiments, the elastic member 6 is an elastic metal bending rod, and the middle part of the metal bending rod forms the limiting part 7 that protrudes outward from the receiving groove 5.

[0021] In some embodiments, a screw hole is provided at the bottom of the receiving groove 5, and a fixing ring 8 or fixing lug is provided at one end of the elastic member 6. The bolt 9 passes through the fixing ring 8 or fixing lug and is screwed into the screw hole to fix the elastic member 6 in the receiving groove 5.

[0022] In some embodiments, after the bolt 9 is tightened, the head of the bolt 9 is recessed into or flush with the opening plane of the receiving groove 5, and is not higher than the receiving groove 5.

[0023] In some embodiments, the limiting part 7 is provided with a first guide slope 10 on the side facing the transmission gear 2 and a second guide slope 11 on the side facing away from the transmission gear 2. The inclination angle of the first guide slope 10 relative to the axis of the main shaft 1 is greater than the inclination angle of the second guide slope 11.

[0024] In some embodiments, the transmission gear 2 has a plurality of positioning pins 12 protruding on one end face facing the warp cylinder 3, and the warp cylinder 3 has a positioning hole 13 corresponding to the positioning pin 12 on one end face near the transmission gear 2. The positioning pin 12 is inserted into the positioning hole 13 to achieve circumferential positioning of the transmission gear 2 and the warp cylinder 3.

[0025] In some embodiments, the receiving groove 5 is a rectangular groove, an arc-shaped groove, or a circular groove.

[0026] This application continuously applies an elastic preload force toward the transmission gear 2 to the bearing 4 through the limiting part 7 of the elastic element 6. This can automatically compensate for the small gaps caused by manufacturing tolerances, bearing 4 wear or vibration, and ensure that the warp roller 3 always maintains a stable axial position when the yarn tension changes at high speed. This effectively prevents its axial movement, deviation or even separation from the main shaft 1, and greatly improves the stability of the warping process and the quality of the yarn.

[0027] During assembly, the via sleeve 3 is pressed against the limiting part 7, and the second guide slope 11 causes it to elastically deform and retract. After the via sleeve 3 is in place, the limiting part 7 springs back and locks the bearing 4. During disassembly, it is only necessary to overcome the elastic force and move the via sleeve 3 slightly towards the transmission gear 2 to disengage it from the limiting part. Compared with traditional screw locking or snap rings, the operation is simpler and faster, and no special tools are required.

[0028] The elastic element 6 is built into the receiving groove 5 of the spindle 1, and the bolt 9 is recessed, resulting in a compact overall structure that does not require additional space. If the elastic element 6 is made of materials such as spring steel, it has good fatigue resistance and service life.

[0029] The limiting part 7 is provided with guide slopes at different angles on both sides. In particular, the steeper first guide slope 10 facilitates the pressing of the bearing 4 into the limiting part during assembly, while the gentler second guide slope 11 provides more stable limiting support and makes disassembly relatively easier.

[0030] The transmission gear 2 and the shaft cylinder 3 are engaged by the positioning pin 12 and the positioning hole 13 to ensure accurate and reliable power transmission and prevent circumferential slippage.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
