Description

Technical Field

[0001] This utility model relates to the field of polypropylene filament processing technology, and in particular to an adjustable tension structure for winding polypropylene filament. Background Technology

[0002] Polypropylene filament is a synthetic fiber produced by polymerizing and melt spinning propylene. Its characteristics include low relative density, low melting point and glass transition temperature, high crystallinity, low moisture absorption, good chemical resistance, and good mechanical properties. Polypropylene is widely used in carpets, burlap sacks, and other applications.

[0003] Polypropylene yarn can become loose during the production process. As the take-up rollers continuously wind up the polypropylene yarn, the wrinkled polypropylene yarn will be squeezed by the later-wound polypropylene yarn, resulting in some polypropylene yarn on the take-up rollers being relatively loose, which affects the winding quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable tension structure for processing and winding polypropylene yarn, thereby solving the problems mentioned in the background section.

[0005] An adjustable tension structure for processing and winding polypropylene filament includes a mounting platform, two spools mounted on both sides of the mounting platform, and an adjustment mechanism mounted in the middle of the mounting platform. The adjustment mechanism includes a motor, a screw fixing frame, a threaded sleeve, a spring, a connecting shaft, a second spool, and a sliding rod. The motor is mounted at the bottom of the mounting platform, the fixing frame is fixedly mounted on the upper surface of the mounting platform, the screw is fixedly mounted at the output end of the motor and rotatably connected to the fixing frame, the sliding rod is fixedly mounted in the middle of the middle plate of the fixing frame, the threaded sleeve is drivenly connected to the screw, the connecting shaft slides along the threaded sleeve and the sliding rod, and is elastically connected to the threaded sleeve through the spring, and the second spool is rotatably mounted at the end of the connecting shaft.

[0006] By adopting the above technical solution, it is convenient to adjust the tension of polypropylene yarn.

[0007] Multiple thread reels are evenly arranged on both sides of the mounting platform, and multiple thread reels are also provided. The multiple thread reels are arranged in a one-to-one correspondence with the multiple thread reels on both sides of the mounting platform.

[0008] By adopting the above technical solution, polypropylene filaments are drawn and placed.

[0009] The spring is located at the upper and lower ends of the threaded sleeve. One end of the spring is connected to the corresponding end of the threaded sleeve, and the other end of the spring is connected to the connecting shaft.

[0010] By adopting the above technical solution, the connecting shaft can slide elastically on the threaded sleeve.

[0011] Ball bearings are installed inside the through hole at the position where the connecting shaft slides along the threaded sleeve and slide rod.

[0012] By adopting the above technical solution, the friction between the connecting shaft and the threaded sleeve and slide rod is reduced.

[0013] The bottom end of the screw is fixed to the motor output end through a shaft passing through the mounting platform.

[0014] By adopting the above technical solution, the screw is driven to rotate.

[0015] The beneficial effects of this utility model of an adjustable tension structure for processing and winding polypropylene yarn are: When the polypropylene yarn becomes loose, the motor can drive the threaded sleeve to move via the screw. The threaded sleeve can drive the connecting shaft to move along the slide bar, and the connecting shaft can simultaneously drive the second thread wheel to move, adjusting the tension of the polypropylene yarn. A spring is installed on the threaded sleeve, which allows the connecting shaft to be in an elastic state on the threaded sleeve. When the second thread wheel is slightly subjected to the force transmitted from the polypropylene yarn, the tension of the polypropylene yarn can be automatically adjusted, making it convenient to adjust the tension of the polypropylene yarn.

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0019] Reference Figure 1-3An adjustable tension structure for processing and winding polypropylene yarn includes a mounting platform 1, a first spool 2 mounted on both sides of the mounting platform 1, and an adjustment mechanism 3 mounted in the middle of the mounting platform 1. The adjustment mechanism 3 includes a motor 301, a screw 302, a fixing frame 303, a threaded sleeve 304, a spring 305, a connecting shaft 306, a second spool 307, and a slide rod 308. The motor 301 is mounted at the bottom of the mounting platform 1, the fixing frame 303 is fixedly mounted on the upper surface of the mounting platform 1, the screw 302 is fixedly mounted at the output end of the motor 301 and is rotatably connected to the fixing frame 303, the slide rod 308 is fixedly mounted in the middle of the middle plate of the fixing frame 303, the threaded sleeve 304 is throttle-connected to the screw 302, the connecting shaft 306 slides along the threaded sleeve 304 and the slide rod 308, and is elastically connected to the threaded sleeve 304 through the spring 305, and the second spool 307 is rotatably mounted at the end of the connecting shaft 306. The device is installed at the corresponding position on the production line. Then, the polypropylene yarn can be wrapped around the top of the first spool 2 on one side of the mounting platform 1, then around the bottom of the corresponding second spool 307, and then wrapped around the top of the corresponding first spool 2 on the other side of the mounting platform 1. This is the traction route of the polypropylene yarn when it passes through the structure. The bottom end of the screw 302 is fixed to the output end of the motor 301 through the shaft through the mounting platform 1. During the operation of the production line, if the polypropylene yarn becomes loose when it is wound, the motor 301 can drive the threaded sleeve 304 to move through the screw 302. The threaded sleeve 304 can drive the connecting shaft 306 to move along the slide bar 308, and the connecting shaft 306 can simultaneously drive the second thread wheel 307 to move, thereby adjusting the tension of the polypropylene yarn. A spring 305 is installed on the threaded sleeve 304, which allows the connecting shaft 306 to be in an elastic state on the threaded sleeve 304. This allows the tension of the polypropylene yarn to be automatically adjusted when the second spool 307 is slightly subjected to the force transmitted from the polypropylene yarn.

[0020] Spring 305 is disposed at the upper and lower ends of threaded sleeve 304. One end of spring 305 is connected to the corresponding end of threaded sleeve 304, and the other end of spring 305 is connected to connecting shaft 306. Ball bearings are disposed inside the through hole opened at the position where connecting shaft 306 slides along threaded sleeve 304 and slide rod 308. At the position where connecting shaft 306 contacts threaded sleeve 304 and slide rod 308, the friction between connecting shaft 306 and threaded sleeve 304 and slide rod 308 is reduced, so that connecting shaft 306 can reduce resistance and move up and down smoothly along threaded sleeve 304 and slide rod 308.

[0021] Multiple thread rollers 1 2 are evenly arranged on both sides of the mounting platform 1, and multiple thread rollers 2 307 are also provided. The multiple thread rollers 2 307 are set one-to-one with the multiple thread rollers 1 2 on both sides of the mounting platform 1; the tension of multiple polypropylene filaments can be adjusted individually.

[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
