Description

TECHNICAL FIELD

[0001] The utility model relates to cloth conveying technical field, concretely is a knitted fabric tension structure. BACKGROUND

[0002] In modern textile industry, especially in the production and processing flow of knitted fabric, the tension control of cloth has been a crucial link. With the continuous improvement of consumers' quality requirements for knitted products, such as the fit of clothing, the clarity and accuracy of printing and dyeing patterns, etc., the tension state control of cloth in the processing process is more and more strict.

[0003] The traditional knitted fabric tensioning method mostly depends on manual adjustment. Workers rely on experience to change the tension of cloth by manually adjusting simple mechanical devices such as taut ropes and rotating screws. However, this manual operation has many drawbacks. On the one hand, manual judgment of cloth tension has strong subjectivity, and it is difficult to ensure that each adjustment can achieve accurate and consistent results, which directly leads to uneven product quality in the same batch and high scrap rate. For example, in the printing and dyeing link, loose cloth may cause pattern distortion and blur, and tight cloth may easily cause uneven dye penetration, affecting the appearance effect. On the other hand, frequent manual operation not only has high labor intensity and low efficiency, but also is difficult to meet the needs of high-speed and continuous production on the fast-paced modern production line, becoming a bottleneck restricting the improvement of production efficiency.

[0004] In recent years, although some semi-automatic or automatic tensioning devices have emerged, they also have their own problems. Some tensioning devices use complex electronic control systems combined with motor-driven adjustment, which can achieve accurate control in theory, but the system is complex, the cost is high, the technical literacy of the operator is high, and the electronic components are prone to failure in the humid and dusty environment of the textile workshop, which has high maintenance cost, making small and medium-sized textile enterprises hesitant. Some devices use mechanical springs, elastic air bags and other elastic elements to achieve tensioning, but their elastic properties will change with the use time and environmental temperature and humidity, making it difficult to maintain stable tensioning force for a long time, resulting in unstable cloth processing quality. Therefore, the utility model provides a knitted fabric tensioning structure. UTILITY MODEL CONTENTS

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The knitted fabric tensioning structure uses the weight of the transmission shaft to drive the movable disc to slide in the arc mouth, thereby pulling the fabric to move down to realize fabric tensioning.

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits the detailed description of known functions and known components to avoid unnecessary confusion of the concept of the present utility model.

[0021] Please refer to Figs. 1-2 A knitted fabric tensioning structure, the knitted fabric tensioning structure of the present application mainly comprises side plates 1, guide rollers 2, arc-shaped openings 3, movable discs 4, transmission shafts 5 and electromagnets 6 and the like.

[0022] The side plate 1 is used as the support main body of the whole structure, is made of high-strength aluminum alloy material, has good rigidity and relatively light weight, can ensure stable support of each component, and is convenient for installation and movement. The side plate 1 can also be arranged on the plate body of the conveying equipment, so as to facilitate integrated installation. A bearing seat structure for installing the guide roller 2 is accurately machined on the side plate 1, so as to ensure that the guide roller 2 can rotate stably and smoothly. The guide roller 2 is made of stainless steel material with smooth surface and wear resistance, and the outer diameter thereof is calculated accurately, so as to effectively guide the knitted fabric to move stably, avoid scratching the surface of the fabric, and reduce the rotation resistance, thereby reducing the loss of fabric transmission power.

[0023] Two arc-shaped openings 3 are symmetrically arranged on the side plate 1, and the two arc-shaped openings 3 are arranged with the guide roller 2 as the center. The bottom end of the arc-shaped opening 3 extends below the guide roller 2, and the top end is flush with the guide roller 2. This design makes the movement track of the movable disc 4 in the arc-shaped opening 3 closely match the cloth path around the guide roller 2, so that it can accurately act on the cloth and achieve efficient tensioning. The inner and outer sides of the arc-shaped opening 3 are finely polished to ensure smoothness, thereby reducing the friction when the movable disc 4 slides. At the same time, the width and depth dimensions of the arc-shaped opening 3 are accurately matched with the connecting components of the movable disc 4, ensuring the stability of the sliding process of the movable disc 4 and preventing jamming or shaking.

[0024] The movable disc 4 is a key component for realizing cloth tensioning function, which mainly consists of a connecting disc 41, connecting columns 42, a fixed disc 43, inner rollers 44 and outer rollers 45. The connecting disc 41 is located inside the arc-shaped opening 3 and is firmly welded with one end of the transmission shaft 5, ensuring that the weight of the transmission shaft 5 can be effectively transmitted to the movable disc 4. The connecting disc 41 is made of carbon steel with appropriate thickness, which has enough strength to bear the tension of the transmission shaft 5 and subsequent cloth. The connecting columns 42 are four in total and are evenly distributed on the edge of the connecting disc 41. They are vertically fixed to the connecting disc 41 and are made of high-strength alloy steel to ensure that they will not deform or break under a large tension. The four connecting columns 42 pass through the arc-shaped opening 3 and are connected to the fixed disc 43 located on the other side of the side plate 1. The fixed disc 43 is fastened to the connecting columns 42 by bolts. This detachable connection method facilitates the installation, maintenance and replacement of the movable disc 4.

[0025] The inner rollers 44 and outer rollers 45 are installed on the connecting columns 42 respectively, and each has two. The inner rollers 44 roll closely along the inner side of the arc-shaped opening 3, and the outer rollers 45 roll along the outer side of the arc-shaped opening 3. They are both made of rubber material, which has good wear resistance, elasticity and low friction coefficient. During the movement of the movable disc 4 in the arc-shaped opening 3 under the weight of the transmission shaft 5 or the traction of external force, the inner and outer rollers 45 not only effectively reduce the friction resistance between the movable disc 4 and the arc-shaped opening 3, making the sliding process smoother, but also ensure that the movable disc 4 always maintains a stable movement posture, avoiding tilting or deviation caused by uneven friction, thereby ensuring the stable application of tension to the cloth.

[0026] The transmission shaft 5 is a metal roller, preferably a solid steel roller with uniform texture and large density, and the diameter and length thereof are reasonably designed according to the width of the fabric and the required tensioning force. One end of the transmission shaft 5 is rigidly connected with the connecting disc 41 of the movable disc 4, and generates downward force by its own weight. When the knitted fabric passes through the guide roller 2, the fabric is partially placed on the transmission shaft 5, and the transmission shaft 5 will drive the movable disc 4 to slide downward in the arc-shaped opening 3 due to the gravity, thereby pulling the fabric to move downward, so that the fabric is always kept in a tensioned state during the transmission process. This tensioning method using the self-weight of the transmission shaft 5 is simple in structure, low in cost, and can adaptively adjust the tensioning force according to the actual situation of the fabric, so as to avoid that the fabric is too loose or too tight, and effectively ensure the quality stability of the knitted fabric in subsequent processing links such as printing, cutting and the like.

[0027] Two electromagnets 6 are installed on the side plate 1 and located on the inner side of the arc-shaped opening 3, the electromagnets 6 are selected from a type with high suction force and low energy consumption, and are connected with an external power supply and a control system, so as to accurately control the on-off state thereof. When the knitted fabric needs to be introduced, first, the movable disc 4 is moved to the initial position above the electromagnets 6, at this time, the control system supplies power to the electromagnets 6, the electromagnets 6 generate a strong magnetic field, and the movable disc 4 is firmly adsorbed and fixed. The operator can conveniently and quickly wind the knitted fabric around the guide roller 2, and make it flatly placed on the transmission shaft 5, and prepare to start the subsequent fabric processing process. After the fabric is introduced, the control system makes the electromagnets 6 off, and the movable disc 4 starts to slide downward under the gravity of the transmission shaft 5, drives the fabric to move downward to realize tensioning, and enters the normal fabric transmission and processing stage.

[0028] Through the ingenious design and cooperative work of the above components, the knitted fabric tensioning structure of the application can efficiently and stably realize the fabric tensioning function in the processing process of the knitted fabric, effectively solves the problems of difficulty in controlling the fabric tensioning degree and complex equipment structure in the prior art, provides a simple, practical and reliable solution for the knitted fabric processing industry, and has a wide market application prospect.

[0029] The above embodiments are only exemplary embodiments of the application, and are not used to limit the application, and the protection scope of the application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the application within the spirit and protection scope of the application, and such modifications or equivalent replacements shall also be considered to fall within the protection scope of the application.
