Description

Technical Field

[0001] This utility model relates to the field of chemical fiber production technology, and in particular to a low-boiling-water shrinkage device for polyester mesh yarn. Background Technology

[0002] In the textile industry, polyester mesh yarn, as a type of polyester fiber, has been widely used in various fields such as clothing, industry, and textiles due to its excellent performance characteristics. In the production process of polyester mesh yarn, controlling its boiling water shrinkage rate is crucial. If the boiling water shrinkage rate is too high, it will bring many problems to subsequent processing and use. Severe shrinkage may lead to color variation, affecting the appearance quality of the product. Excessive shrinkage rate will cause large tension differences, making unwinding difficult and easily causing yarn breakage, increasing the difficulty of weaving. Moreover, the fabric woven from this yarn has poor shape retention and a poor hand feel, which greatly reduces the quality of the product and the user experience.

[0003] Traditional low-boiling-water shrinkage treatment for polyester mesh yarn involves placing a roller containing polyester mesh yarn into a heating device. The device heats the roller, but because the roller has fixed dimensions and cannot expand or contract, the taut polyester mesh yarn generates significant tension on its surface. This causes stress to concentrate in the weakest parts of the yarn, making it prone to breakage. This results in economic losses and necessitates repeating the low-boiling-water shrinkage treatment, impacting work efficiency.

[0004] Therefore, there is an urgent need to provide a low-boiling-water shrinkage device for polyester mesh yarn to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a low boiling water shrinkage device for polyester mesh yarn.

[0006] To solve the above-mentioned technical problems, the present invention provides a low-boiling-water shrinkage device for polyester mesh yarn, comprising a processing box, an opening door rotatably connected to the top of the processing box, a handle fixedly connected to the top of the opening door, two cooling fans installed at the bottom of the opening door, an operating platform installed at the front end of the processing box, a yarn feeding mechanism located at the bottom of the front end of the processing box, a water inlet and a water outlet installed at the rear end of the processing box, two fixing rods fixedly connected to both sides of the processing box, a guide roller rotatably connected between each pair of fixing rods, and an electric heating strip installed inside the processing box.

[0007] The present invention is further configured such that: the wire feeding mechanism includes a protective shell installed at the front end of the processing box, a drive motor is installed inside the protective shell, a drive gear plate is fixedly connected to the output end of the drive motor, a driven gear plate is rotatably connected to the front end of the processing box, a wire collecting roller is installed at the other end of the driven gear plate, a plurality of sliding grooves are opened on the outer wall of the wire collecting roller, a plurality of sliding blocks are slidably connected inside the plurality of sliding grooves, a spring is fixedly connected to the bottom of the plurality of sliding blocks, a limit block is fixedly connected to both sides of the plurality of sliding blocks, and a contact block is fixedly connected to the top of the plurality of sliding blocks.

[0008] With the above technical solution, when the wire feeding mechanism is working, the drive motor is powered on and started. Its output end drives the drive gear plate to rotate. Since the drive gear plate and the driven gear plate mesh with each other, the rotation of the drive gear plate will cause the driven gear plate to rotate accordingly, which in turn drives the wire collecting roller connected to the driven gear plate to rotate synchronously. During the rotation of the wire collecting roller, the polyester mesh yarn is wound on the wire collecting roller. At this time, the contact block will not move towards the center of the wire collecting roller due to the spring force, until the entire section of polyester mesh yarn is wound on the wire collecting roller, thus completing the winding work of the polyester mesh yarn.

[0009] The present invention is further configured such that the driving gear plate and the driven gear plate mesh with each other.

[0010] The above technical solution ensures a constant transmission ratio between the driving gear plate and the driven gear plate, enabling the collecting roller to achieve a stable rotational speed, ensuring uniform polyester mesh yarn feeding speed, and guaranteeing consistent product quality.

[0011] The present invention is further configured such that: the outer wall of the processing box is provided with a through hole corresponding to the collecting roller, and a sealing ring is installed on the inner wall of the through hole.

[0012] Through the above technical solution, the sealing ring can effectively prevent liquid from seeping out from the through hole, avoid contamination of the working environment, prevent liquid waste, and also prevent short circuits and other malfunctions of electrical components caused by liquid leakage.

[0013] The present invention is further configured such that: a plurality of the sliding grooves are arranged in a circular array on the outer wall of the collecting roller with the axis of the collecting roller as the center.

[0014] Through the above technical solution, the ring-shaped contact blocks can make the polyester mesh yarn evenly wound on the surface of the collecting roller, avoiding excessive local tension that could lead to yarn breakage or uneven shrinkage. The symmetrical position of each sliding groove can ensure that all parts of the yarn are heated and stressed evenly during the low boiling water shrinkage treatment, thereby improving the stability of product quality.

[0015] The present invention is further configured such that: the inner wall of the sliding groove is provided with a limiting groove corresponding to the limiting block.

[0016] Through the above technical solution, the limiting groove can provide precise sliding guidance for the limiting block, so that the sliding block can only slide in the sliding groove in the direction defined by the limiting groove, ensuring the straightness and accuracy of the sliding, and avoiding the sliding block from deviating or tilting during the sliding process.

[0017] The present invention is further configured such that a rubber anti-slip layer is provided on the top of the contact block.

[0018] Through the above technical solution, the rough surface of the rubber anti-slip layer can significantly increase the friction between the contact block and the polyester mesh yarn. This helps to clamp the yarn more firmly, prevent the yarn from slipping during the rotation of the yarn collection roller, ensure that the yarn can be wound on the yarn collection roller in a predetermined manner, and improve the accuracy and stability of yarn feeding and take-up.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model designs a wire feeding mechanism that automatically adjusts the position of the contact block according to the tension of the wire through a sliding block and spring system. When the wire is contracted after the low boiling water treatment, the contact block on the wire feeding roller can also slide adaptively to ensure that the wire can always adhere to and wrap around the wire feeding roller. This avoids the problems of wire breakage or loose winding caused by uneven tension in traditional fixed structures. It is especially suitable for polyester mesh yarns with different linear densities.

[0021] 2. This utility model integrates the unwinding of the yarn and the low-boiling water treatment inside the treatment box. The operator only needs to guide the yarn through the lead roller to the unwinding mechanism. After the yarn winding is completed, the opening door can be closed, and the coefficient can be set through the operating table. Then, the treatment box can perform low-boiling water shrinkage treatment on the yarn. The operation is simple and quick. Attached Figure Description

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figures 1-3 A low-boiling-water shrinkage device for polyester mesh yarn includes a processing box 1, an opening door 2 rotatably connected to the top of the processing box 1, a handle 3 fixedly connected to the top of the opening door 2, two cooling fans 4 installed at the bottom of the opening door 2, and an operating table 5 installed at the front end of the processing box 1.

[0030] like Figure 4 and Figure 5 As shown, a wire feeding mechanism 6 is located at the bottom of the front end of the processing box 1. The wire feeding mechanism 6 includes a protective shell 601 installed at the front end of the processing box 1. A drive motor 602 is installed inside the protective shell 601. The output end of the drive motor 602 is fixedly connected to a drive gear plate 603. A driven gear plate 604 is rotatably connected to the front end of the processing box 1. The drive gear plate 603 and the driven gear plate 604 mesh with each other to ensure a constant transmission ratio between the drive gear plate 603 and the driven gear plate 604, so that the collecting roller 605 obtains a stable speed, ensuring uniform wire feeding speed of polyester mesh yarn and ensuring consistent product quality. The other end of the driven gear plate 604 is equipped with a collecting roller 605. The outer wall of the processing box 1 has a through hole corresponding to the collecting roller 605, and a sealing ring is installed on the inner wall of the through hole. The sealing ring can effectively prevent liquid from seeping out from the through hole, avoid contamination of the working environment, prevent liquid waste, and also prevent short circuits and other malfunctions of electrical components caused by liquid leakage.

[0031] like Figure 4 and Figure 5As shown, the outer wall of the collecting roller 605 has multiple sliding grooves 606. These grooves are arranged in a circular array around the axis of the collecting roller 605. The circularly distributed contact blocks 610 ensure that the polyester mesh yarn is evenly wound on the surface of the collecting roller 605, preventing excessive local tension that could lead to yarn breakage or uneven shrinkage. The symmetrical positions of the sliding grooves 606 ensure consistent heating and stress distribution throughout the yarn during the low-boiling-water shrinkage treatment, improving product quality stability. Multiple sliding blocks 607 are slidably connected inside each sliding groove 606. Springs 608 are fixedly connected to the bottom of each sliding block 607, and limit blocks 609 are fixedly connected to both sides of each sliding block 607. The inner wall of the sliding groove 606 has... The limiting block 609 has a corresponding limiting groove, which provides precise sliding guidance for the limiting block 609, so that the sliding block 607 can only slide in the sliding groove 606 along the direction defined by the limiting groove, ensuring the straightness and accuracy of the sliding, and preventing the sliding block 607 from deviating or tilting during the sliding process. The top of the multiple sliding blocks 607 is fixedly connected to a contact block 610. The top of the contact block 610 is provided with a rubber anti-slip layer. The surface of the rubber anti-slip layer is rough, which can significantly increase the friction between the contact block 610 and the polyester mesh yarn. This helps to clamp the yarn more firmly and prevent the yarn from slipping during the rotation of the collecting roller 605, ensuring that the yarn can be wound on the collecting roller 605 in a predetermined manner, and improving the accuracy and stability of the yarn feeding and taking-up.

[0032] like Figure 4 and Figure 5 As shown, when the wire feeding mechanism 6 is working, the drive motor 602 is powered on and started. Its output end drives the drive gear plate 603 to rotate. Since the drive gear plate 603 and the driven gear plate 604 mesh with each other, the rotation of the drive gear plate 603 will cause the driven gear plate 604 to rotate accordingly, thereby driving the wire collecting roller 605 connected to the driven gear plate 604 to rotate synchronously. During the rotation of the wire collecting roller 605, the polyester mesh yarn is wound on the wire collecting roller 605. At this time, the contact block 610 will not move towards the center of the wire collecting roller 605 because of the elastic force of the spring 608, until the entire section of polyester mesh yarn is wound on the wire collecting roller 605, completing the winding work of the polyester mesh yarn.

[0033] like Figures 1-3 As shown, the rear end of the treatment box 1 is equipped with an inlet 7 and an outlet 8, and two fixing rods 9 are fixedly connected to both sides of the treatment box 1. A guide roller 10 is rotatably connected between each pair of fixing rods 9. An electric heating strip 11 is installed inside the treatment box 1.

[0034] In use, the operator opens the top door 2 of the processing box 1 via handle 3, guiding the polyester mesh yarn through the lead roller 10 to the collecting roller 605 of the unwinding processing mechanism 6. The operator then closes the door 2 and starts the drive motor 602 via the operating panel 5. The drive motor 602 rotates the drive gear plate 603, causing the driven gear plate 604 and the collecting roller 605 to rotate synchronously via meshing transmission. During the rotation of the collecting roller 605, the contact block 610 contacts the yarn under the elastic support of the spring 608. The rubber anti-slip layer on its top increases friction, ensuring that the polyester mesh yarn is evenly wound on the surface of the collecting roller 605. After the yarn is completely wound, water is injected into the processing box 1 through the water inlet 7, utilizing electric heating... Step 11 heats water to a low boiling point to shrink the polyester mesh yarn. As the polyester mesh yarn is heated, it begins to tighten. During this tightening process, the polyester mesh yarn applies pressure to the contact block 610. The contact block 610 overcomes the elastic force of the spring 608 and moves towards the center of the collecting roller 605 until the pressure applied by the polyester mesh yarn and the elastic force of the spring 608 are balanced. At this point, the contact block 610 stops moving, and the polyester mesh yarn on the contact block 610 completes the shrinking process. Then, the outlet 8 is opened, and the cooling fan 4 is started simultaneously to drain water and cool the yarn. Finally, the door 2 is opened to remove the yarn, completing the entire low boiling water shrinking process for polyester mesh yarn.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
