Description

Technical Field

[0001] This utility model relates to the textile field, and in particular to a torsional vibration resistant textile roller. Background Technology

[0002] In textile machinery, the cylindrical rotating part that functions in feeding, drafting, and outputting is a transliteration of the English word "roller," encompassing both roller and shaft. It is widely used in drafting, carding, and conveying mechanisms. Based on its function, it is classified into drafting rollers, feeding rollers, pressure rollers, and working rollers. The drafting roller is a key component of the drafting mechanism in a spinning machine, consisting of an upper roller and a lower roller paired together to form the roller gripper, which holds the yarn for drafting.

[0003] However, most of the rollers in existing drafting devices are fixed. During drafting, the tension imbalance of the material will affect the smoothness and stability of the roller conveying, which will affect subsequent feeding and subsequent spinning production.

[0004] Therefore, it is necessary to provide a new anti-torsional vibration textile roller to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anti-torsional vibration textile roller, which solves the problem that most rollers in existing drafting devices are fixed, and the tension imbalance of the material during drafting will affect the smoothness and stability of the roller conveying, thereby affecting subsequent feeding and subsequent spinning production.

[0006] The anti-torsional vibration textile roller provided by this utility model includes a drafting lower roller and a mounting frame. Two uprights are fixed at intervals on one side of the mounting frame. A sliding groove is opened on the opposite side of the two uprights. A lifting platform is arranged between the two uprights. The two sides of the lifting platform are slidably connected to the two sliding grooves respectively.

[0007] The lower drafting roller is movably mounted on the lifting platform, and a motor for driving the lower drafting roller to rotate is installed on one side of the lifting platform.

[0008] In a preferred embodiment, two threaded rods are provided through the mounting frame, both of which pass through the lifting platform and are threadedly connected to the lifting platform.

[0009] Both threaded rods have a stop block fixed to their tops.

[0010] In a preferred embodiment, the mounting bracket and the threaded rod are movably connected by a bearing.

[0011] In a preferred embodiment, a first bevel gear is installed at the bottom of each of the two threaded rods, a limiting seat is fixed at the bottom of the mounting bracket, a rotating shaft is provided through the limiting seat, and two second bevel gears are installed at intervals on the rotating shaft, with the two second bevel gears meshing with the two first bevel gears respectively.

[0012] In a preferred embodiment, a crank is mounted on the rotating shaft.

[0013] In a preferred embodiment, two U-shaped seats are fixed at intervals on the other side of the mounting bracket, and a support seat is installed at the end of the lower drawing roller. The support seat and the two U-shaped seats are fixedly connected by high-strength bolts.

[0014] Two support plates are installed at the center of the lower drawing roller, and the bottom of the support plates is mounted on the mounting frame.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model installs the lower drafting roller and the motor that drives its rotation on a movable lifting platform. By changing the position of the lifting platform, the distance and position between the upper and lower rollers in the guide frame can be adjusted, thereby adjusting the tension of the yarn between the two rollers, thus ensuring the balance and stability of the yarn during drafting, and ensuring the stability of yarn feeding and subsequent production.

[0017] 2. During adjustment, the operator only needs to turn the crank to drive the rotating shaft to rotate. Under the transmission action of the two first bevel gears and the two second bevel gears, the two threaded rods will rotate simultaneously in the same direction, so as to easily adjust the position of the lifting platform along the slide.

[0018] 3. By installing a support seat on the end of the lower drafting roller away from the lifting platform, and then fixing the support seat to the two U-shaped seats together with high-strength bolts, the uniformity of the force on the lower drafting roller can be improved. Combined with the two support plates, the torsional vibration resistance of this lower drafting roller can be greatly improved. Attached Figure Description

With the two support plates 17, the torsional vibration resistance of the lower drawing roller 1 can be greatly improved.

[0028] The working principle of this utility model is as follows: This utility model installs the lower drafting roller 1 and the motor 6 that drives its rotation on a movable lifting platform 5. By changing the position of the lifting platform 5, the distance and position between the upper and lower rollers in the guide frame can be adjusted, thereby adjusting the tension of the yarn between the two rollers, thus ensuring the balance and stability of the yarn during drafting, and ensuring the stability of yarn feeding and subsequent production.

[0029] During adjustment, the operator only needs to turn the crank 13 to drive the rotating shaft 11 to rotate. Under the transmission action of the two first bevel gears 9 and the two second bevel gears 12, the two threaded rods 7 will rotate simultaneously in the same direction, so as to easily adjust the position of the lifting platform 5.
