[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a tension control device for polyester filament production includes an equipment housing 1. A mounting bracket 2 is fixedly installed at the front end of the equipment housing 1. The mounting bracket 2 consists of a mounting base rod 5 and L-shaped mounting plates 6. Two L-shaped mounting plates 6 are symmetrically fixedly installed at the upper and lower ends of the mounting base rod 5. An adjustment assembly 3 is installed on the mounting base rod 5. The adjustment assembly 3 consists of a first base block 8, a support frame 10, rollers 11, a first connecting frame 12, a first connecting arm 13, a second base block 14, a second connecting frame 17, a second connecting arm 18, and a push spring 19. The support frame 10 is fixedly installed... At the front end of the first base block 8, rollers 11 are rotatably mounted on the support frame 10. Two first connecting frames 12 are symmetrically and fixedly mounted on the first base block 8. Two first connecting arms 13 are rotatably mounted on the two first connecting frames 12 respectively. The second base block 14 is located below the first base block 8. Two second connecting frames 17 are symmetrically and fixedly mounted on the second base block 14. Two second connecting arms 18 are rotatably mounted on the two second connecting frames 17 respectively. The first connecting arms 13 and the second connecting arms 18 are rotatably connected together by a pin. A push spring 19 is mounted on the first base block 8. Between block 8 and the second base block 14, fixing pins 20 are inserted into the second base block 14 and the mounting base rod 5. Several guide rollers 4 are installed at the front end of the equipment housing 1. During the production and processing of polyester filament, the polyester filament can be passed sequentially through the guide rollers 4 and simultaneously through the rollers 11. When the polyester filament moves on the guide rollers 4 and the rollers 11, under the elastic force of the push spring 19, the first base block 8, the support frame 10, and the rollers 11 can tension the polyester filament. When the tension of the polyester filament moving on the guide rollers 4 and the rollers 11 decreases, the push spring 19... Under the elastic force, the first base block 8, support frame 10 and roller 11 will slide upward on the mounting base rod 5, thereby tensioning the polyester filament; when it is necessary to adjust the tension of the polyester filament brought by the adjusting component 3, the fixing pin 20 is first pulled out from the second base block 14 and the mounting base rod 5. At this time, the fixing of the second base block 14 will be released, and then the second base block 14 can be moved on the mounting base rod 5, thereby compressing the push spring 19 or causing the push spring 19 to unfold. At this time, the elastic force on the first base block 8 will change, and the thrust on the polyester filament will also change.

[0021] Finally, by setting the mounting bracket 2 and the adjusting component 3, the first base block 8, the support frame 10, and the roller 11 can move on the mounting base rod 5 according to the tension of the polyester filament. When the tension of the polyester filament wound on the guide wheel 4 is small, under the elastic force of the push spring 19, the first base block 8, the support frame 10, and the roller 11 can move upward on the mounting base rod 5 immediately, thereby tightening the polyester filament and preventing it from detaching from the guide wheel 4 due to low tension. This ensures the normal production and processing of the polyester filament. The presence of the first connecting frame 12, the first connecting arm 13, the second base block 14, the second connecting frame 17, the second connecting arm 18, and the fixing pin 20 can adjust the elastic force of the push spring 19 on the first base block 8, thereby adjusting the tension of the polyester filament brought by the adjusting component 3.

[0022] Furthermore, the mounting bracket 2 is located between several guide wheels 4, and the L-shaped mounting plate 6 is fixedly installed at the front end of the equipment housing 1. Several fixing holes 7 are provided on the mounting base rod 5, and the fixing holes 7 pass through the mounting base rod 5 from front to back. The first base block 8 on the adjusting assembly 3 is provided with a first through hole 9, and the first base block 8 passes through the first base block 8 vertically. The first base block 8 is slidably installed on the mounting base rod 5 through the first through hole 9. The second base block 14 on the adjusting assembly 3 is provided with a second through hole 15, and the second through hole 15 passes through the second base block 14 vertically. The second base block 14 is also provided with a mounting hole 16, and the mounting hole 16 passes through the second base block 14 from front to back. The mounting hole 16 and the second through hole 15 are interconnected. The second base block 14 is fitted onto the mounting base rod 5 through the second through hole 15, and the push spring 19 is fitted onto the mounting base rod 5. The fixing pin 20 is inserted into the mounting hole 16 and the fixing insertion hole 7. When the polyester filament moves on the guide wheel 4 and the roller 11, the guide wheel 4 and the roller 11 will rotate. When adjusting the tension of the polyester filament brought by the adjusting component 3, the fixing pin 20 is first pulled out from the mounting hole 16 and the fixing insertion hole 7. At this time, the fixing of the second base block 14 will be released. Then the second base block 14 can be moved up or down on the mounting base rod 5. When the second base block 14 moves up, the push spring 19 will be further compressed. At this time, the elastic force of the push spring 19 on the first base block 8 will increase, so the tension of the polyester filament will also increase. Conversely, when the second base block 14 moves down, the push spring 19 will be unfolded. At this time, the elastic force of the push spring 19 on the first base block 8 will decrease, so the tension of the polyester filament will also decrease.
