Description

Technical Field

[0001] This application relates to the field of polyester opening technology, specifically a polyester opening anti-wrinkle positioning device. Background Technology

[0002] In the production of polyester fabrics, pretreatment processes such as scouring and bleaching are typically required, during which the fabric is often in a rope-like form. To facilitate subsequent processing such as mercerizing, dyeing, and printing, the rope-like fabric needs to be unfolded into a flat state and then dehydrated and dried. However, traditional unfolding equipment easily causes wrinkles and deformation of the fabric during the unfolding process, and the dehydration effect is uneven, affecting the surface quality of the fabric. During the drying stage, improper control of fabric tension or uneven heating can easily cause new wrinkles or shrinkage, reducing the quality of the finished product and production efficiency.

[0003] While some anti-wrinkle devices exist in existing technologies, they are often complex in structure and inconvenient to adjust, making it difficult to simultaneously meet the requirements of wrinkle prevention and uniform drying while achieving efficient dehydration. Therefore, there is an urgent need for a high-efficiency positioning device that can integrate opening, dehydration, wrinkle prevention, and drying functions to improve the overall quality and automation level of polyester fabric processing.

[0004] Chinese patent discloses a fabric opening anti-wrinkle adjustment device (publication number CN217516362U). This patented technology includes an opening roller, an anti-wrinkle mechanism, and a traction mechanism. The anti-wrinkle mechanism includes anti-wrinkle boxes located on both sides of the fabric and symmetrical about the fabric top and bottom, several telescopic rods located inside the anti-wrinkle boxes, and anti-wrinkle rollers fixed on each telescopic rod. A closed-loop groove is opened inside the anti-wrinkle box, and the telescopic rods are slidably connected to the inner wall of the closed-loop groove. The closed-loop groove is provided with a pulley assembly for driving the telescopic rods to slide in the groove and a telescopic assembly for driving the telescopic rods to extend and retract. The fabric passes through the opening roller, the anti-wrinkle mechanism, and the traction mechanism in sequence. The traction mechanism pulls the fabric along the direction from the opening roller to the traction mechanism. The opening roller gradually unfolds the fabric from the middle to both sides. When the fabric passes through the anti-wrinkle mechanism, the anti-wrinkle rollers on both sides pull the fabric to both sides through the extension and retraction of the telescopic rods, so that the fabric gradually flattens out and prevents wrinkles from appearing when the fabric is rolled up.

[0005] However, it does not integrate opening, dehydration, wrinkle prevention and drying functions into one unit, resulting in a low degree of automation. Utility Model Content

[0006] The purpose of this invention is to provide a polyester open-width anti-wrinkle positioning device to solve the problems mentioned in the background art.

Driven by a motor, the anti-wrinkle rollers oscillate periodically, dynamically stretching the fabric and effectively preventing wrinkles caused by uneven tension or thermal shrinkage during drying. Simultaneously, the heating wires and the inlet fan work together to create uniform hot air circulation, accelerating the removal of moisture from the exhaust vents and improving drying efficiency and quality.

Detailed Implementation

[0023] Please see Figures 1-5 In this embodiment of the present invention, a polyester open-width anti-wrinkle positioning device includes a positioning frame 1, an open-width dehydration mechanism 2 is installed on one side of the upper end of the positioning frame 1, and an anti-wrinkle drying mechanism 3 is installed on the other side of the upper end of the positioning frame 1.

[0024] exist Figure 1 and Figure 2 In the middle, the open-width dewatering mechanism 2 includes a gantry 21 fixed on the positioning frame 1. Cylinders 22 are installed through the front and rear sides of the upper end of the gantry 21. Each cylinder 22's output end is connected to a connecting frame 25. An active dewatering roller 20 is installed between two connecting frames 25. A motor 24 is mounted on one end of the active dewatering roller 20, located on one of the connecting frames 25. A pressure sensor 23 is installed between the output end of the cylinder 22 and the connecting frame 25. A driven dewatering roller 28 is installed on the inner side of the gantry 21, below the active dewatering roller 20. A set of fixed frames 26 is installed on the lower side of one end of the gantry 21. A spreading roller 27 is installed between the fixed frames 26. A motor 29 is mounted on one end of the spreading roller 27, located on one of the fixed frames 26. The spreading roller 27 has raised spiral grooves. Both the active dewatering roller 20 and the driven dewatering roller 28 have recessed strip grooves. The dewatering roller 27 is used to dewater the material after boiling, bleaching, etc. After the initial unfolding of the rope-like polyester fabric following the processing steps, it is placed onto the spreading roller 27. Motor 29 drives the spreading roller 27 to rotate, continuously rotating through the raised spiral grooves on the spreading roller 27 to unfold the rope-like polyester fabric into a flat state. The polyester fabric then passes between the active dewatering roller 20 and the driven dewatering roller 28. A cylinder 22 drives the active dewatering roller 20 to descend, pressing the polyester fabric between the active and driven dewatering rollers 20 and 28. Simultaneously, a pressure sensor 23 detects the squeezing pressure exerted on the polyester fabric by the active and driven dewatering rollers 20 and 28 to maintain appropriate pressure. Motor 24 then drives the active dewatering roller 20 to rotate, which in turn drives the driven dewatering roller 28 to rotate, thus pressing out water from the polyester fabric during its transport. The water drains along the recessed grooves on the active and driven dewatering rollers 20 and 28, effectively improving drainage.

[0025] exist Figure 3 and Figure 4In the drying mechanism 3, the anti-wrinkle drying mechanism includes a drying box 31 fixed on the positioning frame 1. A set of inlet fans 37 are embedded in the lower part of the drying box 31, and several exhaust holes 32 are opened at the upper end of the drying box 31. An electric heating wire 36 is installed inside the drying box 31 near the upper end of the inlet fans 37, and a swing anti-wrinkle component 34 is embedded inside the drying box 31 near the upper end of the electric heating wire 36. Both ends of the drying box 31 have strip-shaped holes 35, and a set of guide rollers 33 are installed at both ends of the drying box 31 near the outer side of each strip-shaped hole 35. The opened and dehydrated polyester fabric passes through a set of guide rollers 33 on one side of the drying chamber 31, then enters the drying chamber 31 through the strip hole 35, and exits through the strip hole 35 on the other side. The heating wire 36 generates heat after being energized. Then, external air is sent into the drying chamber 31 through the inlet fan 37. After the air is heated in the drying chamber 31, it passes through the polyester fabric, carrying away the moisture on the polyester fabric and expelling it through the exhaust hole 32. This achieves the drying of the polyester fabric. The dried polyester fabric can be wound up by an external winding device.

[0026] exist Figure 3 , Figure 4 and Figure 5 In the process, the oscillating anti-wrinkle assembly 34 includes an anti-wrinkle roller 341. Oscillating arms 342 are mounted at both the front and rear ends of the anti-wrinkle roller 341. A pull rod 344 is rotatably connected to the outer side of one of the oscillating arms 342. A rotating bar 346 is rotatably connected to one end of the pull rod 344. A motor 345 is mounted at the front end of the rotating bar 346. A rotating shaft 343 is rotatably connected to the lower end of each oscillating arm 342. The rotating shaft 343 is installed inside the drying chamber 31. The anti-wrinkle roller 341, oscillating arms 342, and pull rod 344 are all installed inside the drying chamber 31 and near the upper end of the heating wire 36. The rotating bar 346 and motor 345 are installed on the outer side of the drying chamber 31, and the motor 345 is fixedly mounted. The polyester fabric is mounted on the drying chamber 31. The polyester fabric entering the drying chamber 31 passes through the top of the anti-wrinkle roller 341. The anti-wrinkle roller 341 supports the polyester fabric. The motor 345 drives the rotating bar 346 to rotate. During rotation, the rotating bar 346 pulls the lever 344. Each rotation of the rotating bar 346 pulls and pushes the swing arm 342 once via the lever 344, causing the swing arm 342 to swing left and right once around the rotating shaft 343. During this swing, the swing arm 342 drives the anti-wrinkle roller 341 to swing, repeatedly stretching the polyester fabric, thus preventing wrinkles and improving the drying effect.

[0027] Working principle: When it is necessary to open the rope-shaped polyester fabric after pretreatment processes such as boiling and bleaching, firstly, the rope-shaped polyester fabric is initially opened and placed on the spreading roller 27; then, it is inserted into the drying chamber 31 through the strip hole 35 between the active dewatering roller 20 and the driven dewatering roller 28 and between a set of guide rollers 33; then, it passes through the upper end of the anti-wrinkle roller 341 and exits through the strip hole 35 on the other side of the drying chamber 31, and is wound around the external winding equipment; then, the polyester fabric is kept under a certain tension by the external tension equipment.

[0028] Next, start motor 29. Motor 29 drives the spreading roller 27 to rotate. The spiral groove on the spreading roller 27 rotates continuously, unfolding the rope-like polyester fabric into a flat state.

[0029] After the polyester fabric passes between the active dewatering roller 20 and the driven dewatering roller 28, the active dewatering roller 20 is lowered by the gantry 21, pressing the polyester fabric between the active and driven dewatering rollers 20 and 28. At the same time, the pressure sensor 23 detects the squeezing force of the active and driven dewatering rollers 20 and 28 on the polyester fabric to maintain a suitable pressure. Then, the motor 24 drives the active dewatering roller 20 to rotate, which in turn drives the driven dewatering roller 28 to rotate, so that the water on the polyester fabric is squeezed out during the conveying process. The water is discharged along the recessed grooves on the active and driven dewatering rollers 20 and 28.

[0030] Next, the heating wire 36 is energized, generating heat; then, external air is introduced into the drying chamber 31 via the inlet fan 37. The air is heated inside the drying chamber 31 and passes through the polyester fabric, carrying away the hot steam from the fabric and expelling it through the exhaust port 32; thus achieving the drying of the polyester fabric; During the drying process,

[0031] The rotating bar 346 is driven to rotate by the motor 345. During the rotation, the rotating bar 346 pulls the lever 344. Each rotation of the rotating bar 346 pulls and pushes the swing arm 342 once through the lever 344, causing the swing arm 342 to swing left and right once around the rotating shaft 343. During the swing, the swing arm 342 drives the anti-wrinkle roller 341 to swing. The anti-wrinkle roller 341 repeatedly stretches the polyester fabric, which can prevent the polyester fabric from wrinkling and improve the drying effect.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
