DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0031] As Figure 1 - Figure 2 shown, a tension adjusting device for polyester filament production includes: an upper plate 1, positioning grooves 5 are provided on both sides of the top of the upper plate 1, a first roller 6 is provided inside the positioning grooves 5, steering assemblies 7 are provided at the front and rear ends of the first roller 6, a second roller 8 is provided at the top of the steering assemblies 7, springs 3 are provided around the bottom of the upper plate 1, a bottom plate 2 is provided at the bottom of the springs 3, and a decompression structure 4 is provided in the middle of the front and rear ends of the bottom plate 2;

[0032] An auxiliary structure 9 is provided at the front end of the first roller 6.

[0033] As Figure 1 - Figure 5As shown in the figure, a tension adjustment device for polyester filament production, the pressure reduction structure 4 includes a horizontal plate 401, a vertical plate 402, a vertical groove 403 and a fitting block 404. The middle parts of the front and rear ends of the bottom plate 2 are provided with a horizontal plate 401. The top of the horizontal plate 401 is provided with a vertical plate 402. The inner side of the vertical plate 402 is provided with a vertical groove 403. One end of the vertical groove 403 is provided with a fitting block 404. A sliding structure is formed between the fitting block 404 and the vertical groove 403. When the pressure on the top of the upper plate 1 is too large, the upper plate 1 squeezes the spring 3, and the fitting blocks 404 at both ends of the upper plate 1 slide in the vertical grooves 403 on the inner side of the vertical plate 402. At this time, the pressure received by the upper plate 1 will be reduced:

[0034] The following effects are brought:

[0035] Pressure dispersion and relief: When the pressure on the top of the upper plate 1 is too large, the upper plate 1 will squeeze the spring 3 and disperse the pressure through the sliding of the fitting block 404 in the vertical groove 403, thereby reducing the direct pressure received by the upper plate 1. This helps to prevent the structural parts from deforming or being damaged due to excessive pressure.

[0036] Improved stability: The sliding structure between the fitting block 404 and the vertical groove 403 ensures that the pressure transmission path has a certain guiding property and stability, making the entire pressure reduction process smoother and without unnecessary shaking or instability.

[0037] Adaptive adjustment: This structure can make adaptive adjustments according to the different pressures received by the upper plate 1, enabling the entire device to operate normally under different working loads and maintaining good working performance.

[0038] Extended service life: Through effective pressure reduction and pressure dispersion, the stress borne by each component is reduced, fatigue and wear are decreased, thereby extending the service life of the equipment.

[0039] Easy maintenance: Since the structural design includes sliding and spring 3 components, if there is wear or failure, it is relatively easy to maintain and replace, improving the maintenance convenience of the equipment.

[0040] Such as Figure 1 - Figure 5As shown in the figure, a tension adjustment device for polyester filament production, the auxiliary structure 9 includes a rotating rod 901, a third roller 902 and a clamping block 903. A third roller 902 is provided at the front end of the first roller 6. Clamping blocks 903 are sleeved at both ends of the third roller 902. A rotating rod 901 is provided at one end of the third roller 902. A rotating structure is formed between the rotating rod 901 and the third roller 902. The outer shape of the rotating rod 901 is L-shaped. When the laying length of the polyester material on the surfaces of the first roller 6 and the second roller 8 is too long, rotate the rotating rod 901 at the top of the third roller 902. At this time, the positions of the rotating rod 901 and the third roller 902 are parallel to each other. At the same time, the rotating rod 901 and the third roller 902 can increase the bearing area of the first roller 6 and the second roller 8:

[0041] The following effects are brought:

[0042] Increased bearing area: By rotating the rotating rod 901 of the third roller 902, the rotating rod 901 and the third roller 902 are parallel to each other, thereby increasing the bearing area between the first roller 6 and the second roller 8. This can effectively disperse the weight of the polyester material and prevent indentation or deformation caused by excessive accumulation of the material on the roller.

[0043] Flexible adjustment: The rotating rod 901 is L-shaped and rotatable, enabling the auxiliary structure 9 to flexibly adjust the distance between the rollers and the bearing state according to actual needs. This helps to adapt to polyester materials of different lengths and thicknesses, improving the applicable range and operation flexibility of the equipment.

[0044] Preventing material wrinkling: The increased bearing area helps the material to spread more smoothly on the third roller 902, reducing problems such as wrinkling and accumulation that may occur due to excessive material length, thereby improving the product quality.

[0045] Convenient operation: By simply rotating the rotating rod 901, the distance between the third roller 902 and the first roller 6 and the bearing state can be adjusted, improving the operation convenience and efficiency of the equipment, which is particularly beneficial for quick adjustment during the production process.

[0046] Equipment protection: This structural design reduces the excessive pressure of the material on the third roller 902 and the first roller 6, helps to protect the third roller 902 and the first roller 6 from damage, extends the service life of the equipment, and reduces the maintenance cost.

[0047] More stable movement: Due to the rotating structure composed of the clamping block 903 and the rotating rod 901, the stability and consistency of the third roller 902 and the first roller 6 during the process of increasing the bearing area are ensured, avoiding possible shaking and offset during the rotation process, thereby making the material transfer smoother and more stable.

[0048] Working principle: When using the tension adjusting device for polyester filament production, first lay the polyester material along the second roller 8 and the first roller 6. At the same time, the steering component 7 rotates, and the position between the second roller 8 and the first roller 6 is adjusted. When the pressure at the top of the upper plate 1 is too high, the upper plate 1 squeezes the spring 3, and the fitting blocks 404 at both ends of the upper plate 1 slide in the vertical grooves 403 inside the vertical plate 402. At this time, the pressure received by the upper plate 1 will decrease. When the laying length of the polyester material on the surfaces of the first roller 6 and the second roller 8 is too long, rotate the rotating rod 901 at the top of the third roller 902. At this time, the positions of the rotating rod 901 and the third roller 902 are parallel to each other. At the same time, the rotating rod 901 and the third roller 902 can increase the bearing area of the first roller 6 and the second roller 8. This is the working principle of the tension adjusting device for polyester filament production.

[0049] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
