Description

Technical Field

[0001] The utility model belongs to the technical field of fiber production devices, and in particular relates to a polyurethane fiber production device. Background Art

[0002] Polyurethane fiber, commonly known as spandex, is a highly elastic synthetic fiber. Polyurethane fiber has a high elastic recovery rate and high elongation at break. It can usually be stretched to 4-7 times its original length, and the recovery rate is close to 100%. In the clothing industry, spandex is widely used in tights, sportswear, swimsuits and other clothing that require high elasticity. In addition, it is also used in home furnishings, electronic products, medical devices, and transportation vehicles such as automobiles. The main raw materials of spandex are PTMEG and pure MDI, which are closely related to oil prices. At present, my country's spandex production capacity is in excess, but the industry concentration is relatively high. Leading companies such as Huafeng Chemical have integrated advantages and financial strength to support process technology upgrades and differentiated product development. Polyurethane fiber has a wide range of applications in many fields due to its unique elastic properties. It is an indispensable material in modern life. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of this utility model is to provide a polyurethane fiber production device.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0005] A polyurethane fiber production device comprises a frame, wherein the frame is equipped with a plurality of guide rollers and a tension adjustment mechanism;

[0006] The cam is fixedly mounted on the drive means, and the cam is mounted on two guide wheels, the guide wheels being adapted to move relative to each other for movement of the drive means.

[0007] It is further defined that the first hand-cranked wheel and the second hand-cranked wheel have the same specifications and dimensions. Such a design facilitates replacement of spare parts.

[0008] It is further defined that there are at least four rotating rods. Such a design can be adjusted to four heights, and it is not easy for two adjacent rotating rods to interfere with each other.

[0009] It is further defined that the angle between two adjacent teeth on the circular gear is five degrees. This design ensures the number of adjustable angles.

[0010] It is further defined that the bearing seat is integrally connected with an ear plate, and the frame is provided with a notch with a specification and size matching the ear plate. Such a design further enhances the limiting effect of the bearing seat.

[0011] The beneficial effects of adopting the utility model are:

[0012] With the structural design of the present invention, the turntable can be rotated by rotating the first hand-cranked wheel, and can be fixed by cooperating with the circular gear, thereby changing the height position of the rotating rod installed on the turntable. Because the rotating rod is installed on the turntable in a spiral shape, the position and height of the rotating rod can be adjusted. Combined with the height adjustment of the bearing seat, the adjustment range of the support height is wider and the adaptability is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 、 Figure 2 、 Figure 3 As shown, a polyurethane fiber production device of the present invention includes a frame 1, and the frame 1 is equipped with a plurality of guide rollers 2 and a tension adjustment mechanism 3;

[0022] The tensioning adjustment mechanism 3 includes two sliding grooves 31 symmetrically arranged on the frame 1, and bearing seats 32 are slidably installed in the two sliding grooves 31, and a first hand-cranked wheel 33 is rotatably installed on the bearing seat 32, and the rotating rod of the first hand-cranked wheel 33 is threadedly connected to the frame 1, and a turntable 34 is rotatably installed on the bearing seat 32. A plurality of rotating rods 35 are installed between the turntables 34 on both sides, and the plurality of rotating rods 35 are rotatably installed on the turntable 34, and the plurality of rotating rods 35 are spirally installed on the turntable 34. A circular gear 36 is fixedly installed on the rotating rod of one side of the turntable 34, and a second hand-cranked wheel 37 is fixedly installed on the center line of the circular gear 36. A limiting groove 38 is vertically installed on the side surface of the bearing seat 32, and a stop block 39 is slidably installed in the limiting groove 38. The contact end of the stop block 39 matches the tooth shape of the circular gear 36, and the stop block 39 is rotatably installed with a drawing rod 310. The rotating rod of the drawing rod 310 is provided with a section of external thread 311 near the screwing end, and the external thread 311 is threadedly connected to the limiting groove 38

[0023] In this embodiment, when a polyurethane fiber production device is used, the polyurethane fiber is pulled on the guide roller 2 on the frame 1 and passes through the rotating rod 35 on the tensioning adjustment mechanism 3 on the way. It should be noted here that the advantage of arranging multiple rotating rods 35 on the turntable 34 over arranging only one rotating rod 35 between the turntables 34 is that the arrangement of a single rotating rod 35 will cause the position of the support in the left and right direction to change significantly with the change in height, while the arrangement of multiple rotating rods 35 in a spiral shape can greatly shorten the position deviation in the left and right direction by changing the rotating rods 35 used for support, thereby preventing the limiters on both sides of the rotating rod 35 from drooping significantly.

[0024] When the cam 35 is in the locked position, the lever 310 is rotated to move the lever 311 out of the locking groove 38, and the lever 310 is in the locked position to move the lever 311 out of the locking groove 38.

[0025] In this embodiment, the height of the turntable 34 can be further adjusted to expand the tension adjustment range. The height adjustment method of the turntable 34 is: directly rotate the first hand-cranked wheel 33. Under the effect of the thread, the height adjustment of the bearing seat 32 on the slide groove 31 can be achieved. It should be noted that if the first hand-cranked wheels 33 are provided on both sides of the frame 1, both sides need to rotate synchronously, or the first hand-cranked wheels 33 on both sides are synchronously connected through a connecting rod structure. The connecting rod structure is not difficult to understand in the prior art.

[0026] Preferably, the first hand-cranked wheel 33 and the second hand-cranked wheel 37 have the same specifications and dimensions. Such a design is conducive to the replacement of spare parts. In fact, the specifications and dimensions of the first hand-cranked wheel 33 and the second hand-cranked wheel 37 can be considered according to specific circumstances.

[0027] Preferably, there are at least four rotating rods 35. Such a design can be adjusted to four heights, and two adjacent rotating rods 35 are not likely to interfere with each other. In fact, the number of rotating rods 35 can be considered according to specific circumstances.

[0028] Preferably, the angle between two adjacent teeth on the circular gear 36 is five degrees. This design ensures the number of adjustable angles. In practice, the angle size between two adjacent teeth can be considered according to specific circumstances.

[0029] Preferably, the bearing seat 32 is integrally connected with the ear plate 312, and the frame 1 is provided with a slot 313 whose specifications and dimensions match the ear plate 312. Such a design further enhances the limiting effect of the bearing seat 32. In fact, a structure for ensuring the smooth movement of the bearing seat 32 can be considered according to specific circumstances.

[0030] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
