Description

Technical Field

[0001] The present invention relates to the technical field of textile machinery technology, in particular to a double-side tension control winding device for textile machinery. Background Art

[0002] In the modern textile industry, the production and processing of glass fiber cloth requires high precision and quality control. The loom is the key equipment for weaving yarn or fiber into cloth, and the winding mechanism is an important component to ensure that the cloth can be wound flatly and tightly after weaving. In the glass fiber air-jet loom, the tension control of the winding roller plays a vital role in the flatness and quality of the cloth surface.

[0003] Traditional winding mechanisms usually control the tension of the winding roller by adjusting the length of the tension spring. Although this method has a simple structure, it has significant defects. First, the tension control accuracy is low by relying solely on the adjustment of the tension spring, which is difficult to meet high-precision production requirements. Second, since the tension on both sides of the winding roller cannot be adjusted independently, it is easy to cause uneven tension on the left and right sides, thereby affecting the flatness of the fabric after winding and ultimately affecting the quality of the fabric surface. In addition, the mechanical characteristics of the spring make it respond slowly, making it difficult to maintain the ideal tension state in the rapidly changing production process. Summary of the Invention

[0004] In order to solve the problem of uneven tension of a take-up mechanism and improve textile efficiency, the present invention provides a double-side tension-controlled take-up device for a textile machinery.

[0005] The present invention provides a double-sided tension control take-up device for textile machinery that adopts the following technical solutions: A double-side tension control take-up device for textile machinery, comprising: Roller assembly, horizontally mounted on textile machinery, used for winding cloth during weaving. The pressure roller seat assembly is installed and connected to both sides of the roller assembly to elastically press the roller assembly against each other; The tensioner assembly is installed and connected on both sides of the roller assembly to adjust the elastic tension between the roller assemblies.

[0006] By arranging the tensioner assembly on both sides of the roller assembly, the elastic tension on both sides can be adjusted respectively, solving the problem of uneven tension on the left and right sides caused by single-point adjustment in the traditional winding mechanism. This can significantly improve the flatness of the cloth during winding, avoid wrinkles, offsets or inconsistent tightness during the winding process, thereby effectively improving the quality of the cloth surface. The tensioner assembly can achieve precise tension adjustment to meet the strict requirements of high-quality fabrics such as glass fiber cloth for tension control. This device is not only suitable for standard weaving processes, but also can cope with the tension requirements caused by changes in cloth thickness, material and other factors, thereby ensuring that the wound cloth has excellent flatness and consistency. The pressure roller seat assembly is elastic The pressing method presses the roller group components against each other, effectively reducing the equipment wear caused by mechanical friction, and at the same time reducing the vibration and noise during equipment operation. This design not only improves the stability of equipment operation, but also extends the service life of the device and reduces maintenance costs. The device has a reasonable structural design, simple installation and operation, and is convenient for the maintenance and commissioning of textile machinery. Especially in the production process, the operator can quickly adjust the tensioner assembly to meet the tension requirements of different fabrics, greatly improving production efficiency. This device is suitable for the weaving of glass fiber cloth, and can also be promoted to the winding operation of other textiles. Its high-precision tension control capability enables it to adapt to a variety of materials and process requirements.

[0007] Furthermore, the roller assembly includes a winding roller, which is horizontally installed on the textile machinery and is rollingly installed at both ends through bearings. An upper pressure roller and a lower pressure roller are tightly installed on one side of the winding roller, and the upper pressure roller and the lower pressure roller are respectively tightly installed on the upper and lower parts of the winding roller. A cloth guide rod is installed between the upper pressure roller and the lower pressure roller, and the cloth guide rod is divided into two sections and is distributed tightly on both sides of the winding roller.

[0008] The upper and lower pressure rollers are tightly attached to the upper and lower parts of the take-up roller. Through multi-point support and compression, the cloth is pushed flat during the winding process. This design makes the tension of the cloth on the winding roller more uniform, reducing the problem of uneven tension on both sides caused by the traditional single-point compression method, ensuring the flatness and consistency of the cloth after winding. The guide rod is designed into two sections, which are tightly attached to both sides of the winding roller, effectively guiding the movement path of the cloth, thus preventing the cloth from deflecting or wrinkling during the winding process. The device can maintain stable tension control under rapidly changing production conditions, adapt to the needs of different cloth specifications and materials, and effectively improve the quality of textiles through precise tension adjustment and cloth guidance to meet the strict requirements of the high-end fabric market.

[0009] Furthermore, the pressure roller seat assembly includes a support seat, an upper pressure roller arm and a lower pressure roller arm, the upper pressure roller arm and the lower pressure roller arm are hinged on the support seat, the support seat is fixedly mounted on the side wall of the textile machinery, the swing end of the upper pressure roller arm is connected to the end of the upper pressure roller and controls the swing of the upper pressure roller, and the swing end of the lower pressure roller arm is connected to the end of the lower pressure roller and controls the swing of the lower pressure roller.

[0010] The upper pressure roller arm and the lower pressure roller arm are hinged on the support seat, allowing the pressure roller to swing flexibly during the winding process. By controlling the swing of the upper and lower pressure rollers, it can adapt to cloths of different thicknesses and materials, ensuring that the pressure rollers continuously and evenly press the cloth. This design improves the device's ability to control cloth tension, reduces the occurrence of unevenness and wrinkles, and improves the winding quality. The support seat is fixedly installed on the side wall of the textile machinery, providing a stable support base for the upper and lower pressure roller arms. Through precise control of the swing arm, the upper and lower pressure rollers can apply appropriate pressure to the cloth to ensure uniform distribution of tension during the winding process. Especially when processing high-quality fabrics, this precise pressing design can significantly improve the flatness and consistency of the cloth to meet strict production quality standards.

[0011] Furthermore, the swinging ends of the upper and lower pressure roller arms are equipped with spring pull rods, and the spring pull rods are connected to and equipped with tension springs at one end away from the upper and lower pressure roller arms. The tension springs are fixed to the side wall of the textile machinery at one end away from the spring pull rods through a spring support rod.

[0012] The combined design of the spring pull rod and the tension spring enables the upper and lower pressure roller arms to automatically adjust the applied pressure according to the thickness and material of the cloth. This automatic adjustment mechanism improves the adaptability of the pressure roller to different types of cloth, ensures that the pressure distribution is always uniform during the winding process, and improves the flatness and quality of the cloth. The tension spring is fixed to the side wall of the textile machinery through the spring support rod, providing additional stable support for the pressure roller arm, ensuring that the pressure roller presses the cloth stably, and further improving the operating stability of the equipment and product quality.

[0013] Furthermore, the upper pressure roller arm and the lower pressure roller arm are hinged on the support seat through a pressure roller pin shaft, and a pressure roller bushing is sleeved at the contact point between the pressure roller pin shaft and the upper pressure roller arm and the lower pressure roller arm, and a pressure roller washer is padded at the contact point between the end of the pressure roller pin shaft and the pressure roller bushing, and the pressure roller washer is an elastic washer.

[0014] The roller pin contacts the upper and lower roller arms via roller bushings. The bushings effectively reduce direct friction between the pin and the arms. This design reduces wear and extends the life of the pin and roller arms. Roller washers provide additional cushioning and elastic support at the contact point between the pin end and the bushing. These elastic washers absorb minor vibrations and shocks during mechanical movement, enhancing articulation stability and reducing slippage.

[0015] Furthermore, the upper and lower pressure roller arms are connected to the upper and lower pressure rollers via pressure roller bearings, and bearing retaining rings are installed on the end faces of the pressure roller bearings.

[0016] The addition of the pressure roller bearing effectively reduces the sliding friction between the upper and lower pressure rollers and the pressure roller arm, and instead adopts rolling friction. This design significantly reduces the movement resistance, ensures the smooth movement of the pressure roller, and improves the efficiency of the equipment operation and the smoothness of operation. The bearing retaining ring is installed on the end face of the pressure roller bearing to play a fixing and protective role. The bearing retaining ring can effectively prevent the bearing from being subjected to lateral loads or external force impact, thereby reducing bearing wear and damage.

[0017] Furthermore, the tensioner assembly includes a card plate, a guide rod fixing seat, a spring fixing seat, a connecting pull rod and a compression spring. The card plate and the guide rod fixing seat are connected and fixed to each other. The card plate is fixedly clamped on the end of the upper pressure roller. The guide rod fixing seat is connected to the cloth guide rod and controls the cloth guide rod to swing around the upper pressure roller. A connecting pull rod is connected to one side of the card plate. The connecting pull rod is used to control the swing of the card plate and the guide rod fixing seat. The connecting pull rod is elastically installed on the guide rod fixing seat through a compression spring.

[0018] The connecting rod is elastically connected to the guide rod fixing seat through a compression spring, providing a flexible tension adjustment mechanism. The compression spring allows automatic adjustment when the tension of the fabric changes, thereby improving the accuracy of tension control and ensuring the tension consistency and product quality of the fabric during the winding process. The design of the connecting rod enables the swing of the pallet and the guide rod fixing seat to be precisely controlled.

[0019] Furthermore, the clamping plate is provided with a through hole for clamping the upper pressure roller, and a notch is provided on one side of the through hole and the size of the notch can be adjusted by tightening bolts.

[0020] By designing through holes and adjustable notches on the pallet, the size of the notch can be adjusted according to actual needs during installation. This flexibility enables the pallet to adapt to upper pressure rollers of different sizes and specifications, simplifies the installation process of the equipment, and improves installation efficiency. The design of the fastening bolts allows the user to accurately adjust and lock the through hole notch after installation. By adjusting the size of the notch, the close connection between the pallet and the upper pressure roller can be ensured to avoid loosening or sliding, thereby improving the stability of the equipment operation.

[0021] Furthermore, the spring fixing seat is fixedly mounted on the side wall of the textile machinery via a pressure roller mounting plate.

[0022] The spring retainer is firmly mounted on the side wall of the textile machinery through the pressure roller mounting plate, ensuring that the component has sufficient support and stability during operation.

[0023] Furthermore, one end of the connecting rod is provided with a joint bearing and is hinged to the clamping plate through the joint bearing, and the other end of the connecting rod is telescopically connected through the tension adjustment rod and the long screw rod. Both ends of the tension adjustment rod are threaded holes and are threadedly connected to the connecting rod and the long screw rod respectively. The compression spring is sleeved on the long screw rod and controls the telescopic movement of the long screw rod. Adjustment nuts are installed at both ends of the compression spring, and the adjustment nut at the bottom end of the compression spring is installed at the bottom of the long screw rod through threads, and the adjustment nut at the top is movably sleeved on the top of the long screw rod.

[0024] One end of the connecting rod is provided with a joint bearing and is hinged to the clamping plate, providing flexible rotation and angle adjustment capabilities. Through the threaded hole of the tension adjustment rod, it is threadedly connected to the connecting rod and the long lead rod respectively, so that the tension can be accurately adjusted. The adjustment nuts at both ends of the compression spring enable the pressure of the compression spring to be accurately adjusted to ensure the adaptability of the equipment under different working conditions. The adjustment nuts at both ends of the compression spring are easy to adjust and lock. The operator can adjust and lock the tension with a simple rotation action, which improves the simplicity and efficiency of maintenance.

[0025] In summary, the present invention has the following beneficial technical effects: 1. The combined design of the take-up roller, upper pressure roller, lower pressure roller and cloth guide rod ensures that the cloth is evenly stressed during the take-up process, avoids slipping or wrinkling of the cloth, and improves the take-up quality. The elastic compression design ensures that the take-up roller and the cloth always maintain good contact, thereby improving the stability of operation.

[0026] 2. Through the coordinated work of the connecting rod, spring fixing seat and compression spring, the precise tension adjustment of the upper pressure roller and the cloth guide rod is achieved to adapt to the tension requirements of different weaving processes. The tension spring provides elastic tension to ensure that the equipment can automatically adapt to the tension changes of the cloth during operation, avoiding frequent manual adjustments and improving production efficiency.

[0027] 3. Through the hinged design, the upper and lower pressure roller arms can swing flexibly, which makes it easy to adjust the distance between the pressure roller and the winding roller to adapt to different cloth thicknesses and process requirements. The tension can be adjusted through the thread, so that the device can adapt to different production environments and cloth tension requirements, thereby improving the versatility of the equipment.

[0028] 4. A roller bushing is installed between the roller pin and the upper roller arm and the lower roller arm to reduce friction between components, improve operating stability, and extend the service life of the equipment. An elastic washer is added to the end of the roller pin to absorb vibration and impact, effectively reducing wear on components and further extending the service life of the device.

[0029] 5. The clamping plate fixes the upper pressure roller through the through hole and the notch. The size of the notch can be adjusted by fastening the bolt, which is convenient for quick disassembly and assembly of the pressure roller and shortens the maintenance time. The adjustment nuts are set at both ends of the pressure spring, which is convenient for the operator to quickly adjust the tension and reduce the difficulty of maintenance.

[0030] 6. A bearing retaining ring is installed on the end face of the pressure roller bearing to prevent the bearing from loosening during operation, thereby improving the safety of equipment operation. Through the application of components such as tension springs, compression springs and elastic washers, impact force and vibration are absorbed during operation, reducing the risk of equipment failure.

[0031] 7. The spring fixing seat is fixed on the side wall of the textile machinery through the pressure roller mounting plate, which makes full use of the side wall space, does not occupy the internal space of the equipment, and is convenient for the arrangement of other components.

[0032] 8. The cloth guide rod is divided into two sections and is close to both sides of the winding roller to ensure the guiding stability of the cloth during the winding process, improve the neatness and flatness of the cloth, and realize precise control of the cloth tension through the tensioner assembly, reduce the cloth deformation problem caused by uneven tension, and improve the quality of the final product.

A cloth guide rod 34 is installed between the upper pressure roller 32 and the lower pressure roller 33. The cloth guide rod 34 is divided into two sections and is respectively distributed tightly on both sides of the winding roller 31.

[0039] The roller group assembly 3, the pressure roller seat assembly 1 and the tensioner assembly 2 are combined into a whole, and then the whole is installed on the textile device.

[0040] After starting the textile machine, ensure that the take-up roller 31, the upper pressing roller 32 and the lower pressing roller 33 maintain good contact with the cloth during operation.

[0041] Adjust the tensioner assembly 2 and change the pressure of the compression spring by rotating the tension adjustment rod to adapt to the tension requirements of different cloths.

[0042] Check the wear of bearings and bushings regularly and lubricate or replace them when necessary to ensure smooth operation of the equipment.

[0043] Before operating the equipment, be sure to check whether all connecting parts are firm, especially the spherical bearings and fastening bolts, to ensure that the equipment is safe and reliable during high-load operation. If unstable tension or poor operation of the take-up roller 31 is found, check the connection status of the tensioner assembly and the pressure roller seat assembly in time to ensure that all elastic components are working properly. According to the characteristics of different fabrics, fine-tune the tensioner assembly to optimize the textile process and improve production quality.

[0044] Example 2: On the basis of Example 1, it is supplemented: Reference Figure 2 The pressure roller seat assembly 1 includes a support seat 11, an upper pressure roller arm 12 and a lower pressure roller arm 13. The upper pressure roller arm 12 and the lower pressure roller arm 13 are hinged on the support seat 11. The support seat 11 is fixedly installed on the side wall of the textile machinery. The swing end of the upper pressure roller arm 12 is connected to the end of the upper pressure roller 32 and controls the swing of the upper pressure roller 32.

The tension springs 151 are fixed to the side wall of the textile machine at one end away from the spring pull rods 15 through a spring support rod 152.

[0046] Reference Figure 2 The upper roller arm 12 and the lower roller arm 13 are hinged on the support seat 11 through a roller pin 122.

[0048] Start the textile machinery and ensure that the upper pressure roller 32 and the lower pressure roller 33 maintain good rolling contact with the winding roller 31 through the pressure roller bearing 14. Check whether the upper pressure roller arm 12 and the lower pressure roller arm 13 swing flexibly, and ensure that the spring pull rod 15 and the tension spring 151 work together to provide appropriate elastic pressing force.

[0049] According to the thickness and tension requirements of the cloth, the elastic compression degree of the pressure roller arm is changed by adjusting the preload of the tension spring 151. If greater tension is required, the tension of the tension spring 151 can be appropriately increased. If the tension is too large, the spring can be appropriately loosened. The adjustment is achieved by rotating the spring pull rod 15 to adjust the length of the spring pull rod 15.

[0050] During the operation of the equipment, regularly check the status of key components such as the pressure roller pin 122, the pressure roller bushing 121, and the pressure roller bearing 14 to ensure their normal operation, and observe whether the cloth is wound smoothly. If it is found that the cloth tension is uneven or the pressing force is insufficient, the preload state of the tension spring 151 can be adjusted in time.

[0051] Example 3: On the basis of Example 1, it is supplemented: Reference Figure 3 The tensioner assembly 2 includes a card plate 21, a guide rod fixing seat 22, a spring fixing seat 24, a connecting rod 25 and a compression spring 26.
