Description

Technical Field

[0001] The utility model relates to the field of polyester fiber production, and relates to a polyester fiber winding device. Background Art

[0002] Polyester fiber, commonly known as "polyester", is a synthetic fiber obtained by spinning polyester formed by the polycondensation of organic dibasic acid and diol, referred to as PET fiber, which belongs to a polymer compound. The biggest advantage of polyester fiber is its good wrinkle resistance and shape retention, and it has high strength and elastic recovery ability. It is durable, wrinkle-resistant, iron-free, and non-sticky. During the manufacturing process, the polyester fiber needs to be rolled through a winding device.

[0003] However, polyester fibers tend to become loose during the winding process, resulting in the winding being not tight enough, causing the internal polyester fibers to fold, thus affecting the winding quality.

[0004] Therefore, in order to solve the deficiencies in the prior art, a polyester fiber winding device with a simple structure needs to be designed. Utility Model Content

[0005] The utility model provides a polyester fiber winding device to solve the problems of the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions: A polyester fiber winding device includes: a bracket, a motor, an air expansion shaft, a pre-tightening assembly and a support assembly, the motor is arranged at one end of the bracket and drives the air expansion shaft to rotate, the pre-tightening assembly includes a lifting cylinder, an upper base plate, a vertical plate, a fixed cylinder, a sliding rod, a spring, a lower base plate and a pressure wheel, the lifting cylinder is arranged on the upper base plate, the vertical plate is fixed to the lower end of the upper base plate, the upper end of the vertical plate is provided with a guide hole 1, the sliding rod is slidably arranged on the vertical plate, the upper end of the sliding rod is provided with a guide hole 2, the fixed cylinder is arranged at the lower end of the upper base plate and the piston rod is passed through the guide hole 1 and the guide hole 2, the lower base plate is fixed to the lower end of the sliding rod, the pressure wheel is arranged at the lower end of the lower base plate, the spring is sleeved on the sliding rod, and the support assembly is arranged at the left end of the air expansion shaft.

[0007] As a further improvement, a rubber ring is sleeved outside the pressing wheel.

[0008] A further improvement is that the support assembly includes a linear guide assembly one, a linear guide assembly two, a cylinder three and a sleeve seat, the linear guide assembly one is arranged at the left end of the bracket, the linear guide assembly two is arranged at the upper end of the linear guide assembly one, the cylinder three is arranged at the upper end of the linear guide assembly two, and the sleeve seat is arranged at the upper end of the cylinder three.

[0009] As a further improvement, the vertical plate, the fixed cylinder, the sliding rod, the spring and the lifting cylinder are symmetrically arranged in two groups.

[0010] Compared with the prior art, the polyester fiber winding device of the utility model has the following beneficial effects:

[0011] The polyester fiber paper roll is sleeved on the air expansion shaft and fixes the paper roll, and then the motor is started to drive the air expansion shaft to wind. During the winding process, the diameter of the polyester fiber paper increases, pushing the pressure wheel to move upward, and the spring at the upper end of the pressure wheel is compressed, ensuring that the pressure wheel always has a certain pre-tightening force on the polyester fiber paper roll, thereby improving the winding tightness, avoiding the folding of the internal polyester fiber, and improving the winding quality; when the roll diameter is too large, the lifting cylinder drives the upper base plate to move upward, increasing the space above the spring, and preventing the pressure wheel from excessively pressing the paper roll; when winding is required, the piston rod of the fixed cylinder passes through guide hole one and guide hole two to prevent the pressure wheel from sliding down under the action of gravity, and the lifting cylinder further drives the upper base plate to move upward, so that the pressure wheel is away from the paper roll, which is convenient for unloading the paper roll.
