Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester production technology, and in particular to a stretching device for producing high-elastic polyester fabric. Background Technology
[0002] High-elastic polyester fabric is a synthetic fiber fabric, mainly composed of polyester fiber and elastic fiber. Due to its excellent elasticity, abrasion resistance and wrinkle resistance, it has been widely used in many fields such as clothing, home decoration, and sporting goods. In the processing of high-elastic polyester fabric, it goes through many processes, one of which is the stretching of polyester filament.
[0003] In existing polyester filament stretching devices, the heating and stretching process of polyester filament is completed by the cooperation of pressure rollers and heating rollers. However, since both pressure rollers and heating rollers come into contact with the polyester filament, the upper and lower parts of the polyester filament may be unevenly heated due to temperature differences when the heating roller heats the polyester filament, which can easily affect the stretching effect of the polyester filament. In addition, dust particles are easily attached to the surface of the heating roller during use, which can also affect the heating effect of the polyester filament. Therefore, a stretching device for the production of high-elastic polyester fabric is proposed. Utility Model Content

This device can solve the problems that when the polyester filament is heated and stretched by the combination of pressure roller and heating roller, the upper and lower parts of the polyester filament may be heated unevenly due to temperature difference, which may affect the stretching effect of the polyester filament. In addition, the heating roller is prone to dust particles adhering to its surface during use, which may also affect the heating effect of the polyester filament.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stretching device for producing high-elastic polyester fabric, comprising a support frame, an unwinding roller, a winding motor, and a winding roller, and further comprising a lower pressure roller, an upper pressure roller, a connecting mechanism, a heating mechanism, a scraper, and a collecting mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This application achieves uniform heating of polyester filament by setting up a lower pressure roller, an upper pressure roller, a connecting mechanism, and a heating mechanism. The connecting mechanism includes a slide bar, a lifting plate, a spring, and a connecting plate. The heating mechanism includes a first fixed plate, a first heating rod, a second fixed plate, and a second heating rod. In use, the first heating rod and the second heating rod are activated to transfer heat to the lower pressure roller and the upper pressure roller, respectively. Under the elastic force of the spring, the upper pressure roller can press the polyester filament onto the lower pressure roller. Then, the polyester filament is heated by the lower and upper pressure rollers. When the polyester filament moves, it will drive the lower and upper pressure rollers to rotate. The polyester filament is subjected to traction force, thereby completing the stretching of the polyester filament. This effectively avoids uneven heating of the upper and lower parts of the polyester filament due to temperature difference, thus ensuring the stretching effect of the polyester filament.
[0014] 2. This application achieves the function of cleaning dust particles adhering to the surface of the lower and upper pressure rollers by setting up a scraper, a collection mechanism, a pusher, and a connecting rod. The collection mechanism includes a collection box and a dust removal trough. During use, the scraper cleans the dust particles adhering to the surface of the rotating lower and upper pressure rollers. The dust particles enter the collection box for collection, effectively preventing dust particles from adhering to the outer surface of the lower and upper pressure rollers and affecting the heating effect of the polyester filament. After use, pulling the connecting rod can move the pusher to push the dust particles inside the collection box to the dust removal trough for discharge. Attached Figure Description
