AI Technical Summary
Existing polyester yarn tension adjustment mechanisms cannot adjust the tension of a single yarn individually, thus failing to meet personalized tension requirements.
A polyester yarn conveying tension adjustment mechanism was designed. The movement of the longitudinal slide and the longitudinal slider is controlled by the first and second control mechanisms respectively to achieve individual tension adjustment of a single yarn. The tension of the two guide groups is synchronously adjusted by simultaneously controlling the movement of the two tensioning wheels.
It enables independent tension adjustment of a single yarn and synchronous tension adjustment of two conductor groups, meeting the flexible adjustment requirements for different tension needs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, specifically to a polyester yarn conveying tension adjustment mechanism. Background Technology
[0002] Polyester yarn refers to yarn spun from polyester, which is a type of polymer fiber produced by spinning.
[0003] In the current polyester yarn conveying process, we often need to use a tension adjustment mechanism to ensure that the polyester yarn remains taut during the conveying process. Existing tension adjustment mechanisms, such as the yarn tension adjustment device for recycled yarn textile with publication number CN217229797U, involve activating two hydraulic cylinders. The piston rods of the two hydraulic cylinders drive the second rotating shaft and all the second winding wheels on the second rotating shaft to adjust their height upwards, thus facilitating the adjustment of the tension of all the yarns to be wound. However, this adjustment method can only adjust the tension of all the yarns at the same time. Obviously, it cannot be done when the user needs to adjust the tension of a single yarn. Utility Model Content
[0004] The purpose of this invention is to solve the technical problem of providing a polyester yarn conveying tension adjustment mechanism that can adjust the tension of a single yarn.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model for a polyester yarn conveying tension adjustment mechanism is as follows:
[0006] The device includes a mounting base with a partition connected to its front side; wire guides are connected to both sides of the partition; each wire guide includes an upper wire guide wheel rotatably connected to the top of the partition and a lower wire guide wheel rotatably connected to the bottom of the partition; a longitudinal slider is slidably connected to the middle of the partition; adjusting seats corresponding to the two wire guides are connected to the left and right sides of the longitudinal slider; a longitudinal slide block is slidably connected to each adjusting seat; a tensioning wheel is rotatably connected to each longitudinal slide block; a first control mechanism for controlling the longitudinal position of the longitudinal slide block is connected to each longitudinal slide block; and a second control mechanism for controlling the longitudinal position of the longitudinal slider is connected to the partition.
[0007] A fixing panel is connected to the rear side of the mounting base; the fixing panel has connection holes.
[0008] The first control mechanism is a first longitudinal screw rotatably connected to the adjusting seat; the first longitudinal screw is threadedly connected to the longitudinal slide, and the front end of the first longitudinal screw passes through the adjusting seat and is connected to a first bolt head.
[0009] The second control mechanism is a second longitudinal screw rotatably connected to the partition plate; the second longitudinal screw is threadedly connected to the longitudinal slider, and the front end of the second longitudinal screw passes through the partition plate and is connected to a second bolt head.
[0010] The mounting base is connected to a reinforcing rib on its rear side.
[0011] Both the upper guide wheel and the lower guide wheel are connected to a fixed disc on their sides; the fixed disc is connected to the partition plate by bolts.
[0012] The technical effects achievable by this utility model are as follows: The polyester thread conveying tension adjustment mechanism of this utility model can control the adjustment seats on both sides of the longitudinal slider to move longitudinally together by rotating the second longitudinal screw, thereby simultaneously controlling the longitudinal movement of the two tensioning wheels and thus simultaneously adjusting the tension of the polyester thread on the two guide groups; Furthermore, this utility model can also control the longitudinal movement of the longitudinal slide connected to the first longitudinal screw by rotating the first longitudinal screw, thereby independently adjusting the tension of the polyester thread on the guide group corresponding to the longitudinal slide. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] See Figures 1 to 3 .
[0019] A polyester thread conveying tension adjustment mechanism includes a mounting base 1, a fixed panel 11 connected to the rear side of the mounting base 1, and a connecting hole 12 on the fixed panel 11 for easy fixing of the fixed panel 11 through the connecting hole 12; preferably, a reinforcing rib 31 is connected to the rear side of the mounting base 1.
[0020] The mounting base 1 has a partition 2 connected to its front side, and wire assemblies are connected to both sides of the partition 2. The wire assemblies include an upper wire wheel 3 rotatably connected to the top of the partition 2 and a lower wire wheel 4 rotatably connected to the bottom of the partition 2. Preferably, the upper wire wheel 3 and the lower wire wheel 4 are both connected to a fixing disc 41 on their sides. The fixing disc 41 is connected to the partition 2 by bolts. The upper wire wheel 3 and the lower wire wheel 4 are connected by the above-mentioned detachable connection structure, which facilitates replacement after damage.
[0021] A longitudinal slider 5 is longitudinally slidably connected to the middle of the partition 2. Adjustment seats 6 corresponding to the two wire groups are connected to the left and right sides of the longitudinal slider 5 respectively. A longitudinal slide block 7 is longitudinally slidably connected to each adjustment seat 6. A tension wheel 8 is rotatably connected to each longitudinal slide block 7. A first control mechanism for controlling the longitudinal position of the longitudinal slide block 7 is connected to each longitudinal slide block 7. Specifically, the first control mechanism is a first longitudinal screw 21 rotatably connected to the adjustment seat 6. The first longitudinal screw 21 is threadedly connected to the longitudinal slide block 7, and the front end of the first longitudinal screw 21 passes through the adjustment seat 6 and is connected to a first bolt head 22. This utility model can independently control the longitudinal movement of the longitudinal slide block 7 threadedly connected to the first longitudinal screw 21 by rotating the first longitudinal screw 21, thereby independently adjusting the longitudinal position of the tension wheel 8 rotatably connected to the adjustment seat 6, thereby independently adjusting the tension of the polyester thread corresponding to the tension wheel 8.
[0022] A second control mechanism for controlling the longitudinal position of the longitudinal slider 5 is connected to the partition plate 2. Specifically, the second control mechanism is a second longitudinal screw 23 rotatably connected to the partition plate 2. The second longitudinal screw 23 is threadedly connected to the longitudinal slider 5, and the front end of the second longitudinal screw 23 passes through the partition plate 2 and is connected to a second bolt head 24. By rotating the second longitudinal screw 23, this utility model can simultaneously control the longitudinal movement of the two adjusting seats 6, thereby simultaneously adjusting the longitudinal position of the two adjusting seats 6. The longitudinal position of the tensioning wheel 8 located on the two adjusting seats 6 also changes accordingly, thereby simultaneously adjusting the tension of the polyester thread on the two guide wire groups.
[0023] In summary, this invention can not only adjust the tension of the polyester threads on both conductor groups simultaneously, but also adjust the tension of the polyester threads on one conductor group individually.
