[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0028] In an exemplary embodiment, Figure 1 As shown, a stretching sensor device based on a covering structure is provided, including an area detection sensor 3 and a stretching buncher; the area detection sensor 3 is connected to the stretching buncher; the area detection sensor 3 and the stretching buncher are both arranged on the transmission path of the core yarn, when the area of the core yarn passing through the area detection sensor 3 changes, the area detection sensor 3 generates tension, and transmits the tension to the stretching buncher, so that the stretching buncher stretches and bundles the core yarn with the changed area, and pulls the core yarn with the changed area back to a straight state.
[0029] The working principle of the above-mentioned area detection sensor 3 is: since the area detection sensor is designed with an asymmetric electrode plate, the upper electrode plate is offset to the left by default, and the lower electrode plate is offset to the right by default. When the area of the core yarn passing through the area detection sensor changes, the capacitance changes, which will increase the electrode offset and generate a lateral force acting on the pressure rod, thereby generating tension.
[0030] The present invention discloses a draft sensor device based on a coated structure spinning process. The device uses a sensor to detect whether the core yarn is folded or blown during conveying, and applies tension to stretch and bundle the abnormal fibers into a straight state when these phenomena occur. The device primarily comprises an area detection sensor 3 and a drafting and bundling device. The area detection sensor 3 is responsible for detecting whether the conveyed yarn is in a straight state. If fiber folds or blown fibers occur, the area detection sensor generates and transmits pressure upon detection. The drafting and bundling device then receives the pressure and stretches and bundles the fed abnormal core yarn, restoring it to a straight state.
[0031] In an exemplary embodiment, the area detection sensor 3 is a capacitive sensor for detecting the change in the core yarn area, and includes two parallel electrodes, a metal shell, and a medium filled between the two parallel electrodes.
[0032] In an exemplary embodiment, the above-mentioned area detection sensor 3 is connected to a power supply, and a power manager is provided in the power supply. The power manager is used to convert the input voltage into the voltage required by the area detection sensor 3 and provide the necessary current to ensure that the area detection sensor 3 can work normally and output accurate measurement data.
[0033] In an exemplary embodiment, the area detection sensor 3 is provided with a USB data interface, which can communicate with other devices and transmit data to a computer or other controller.
[0034] Conventional fiber bundle concentrating devices include an intermediate shaft that rotationally drives a pair of conveyor rollers that convey the fiber bundle. In fiber bundle concentrating devices, the intermediate shaft is supported by a precisely configured, rotatable bearing. Axial loads are applied to the rotatable bearings, which are secured by setscrews. If a thrust load greater than the friction between the setscrews and the bearings is generated, this can cause bearing misalignment.
[0035] To avoid the above-mentioned phenomenon, in an exemplary embodiment, a drafting and bunching device without an intermediate shaft is provided, comprising two pressure rods 4, two springs 5, and a drafting and bunching device 6. One end of each of the pressure rods 4 is disposed on either side of the metal housing of the area detection sensor 3; the two springs 5 are detachably disposed on the other ends of each of the pressure rods 4; and the drafting and bunching device 6 is located between the two springs. The pressure rods on both sides are symmetrically arranged. When the area detection sensor 3 detects changes in the core yarn area, such as folding or bursting, the pressure rods transmit pressure to the springs 5, and then to the drafting and bunching device 6. Specifically, when the core yarn is normal, the springs 5 are not compressed, and no additional tension is applied to the core yarn for drafting and bunching.
[0036] In another exemplary embodiment, springs with different wire diameters and different effective coil numbers can be replaced to accommodate different core yarn materials.
[0037] In an exemplary embodiment, the drafting tensioner 6 is composed of a group of parallel curved metal sheets to perform normal drafting and bundling on the core yarn.
[0038] The drafting and bunching device of the present application generates tension by compressing and deforming springs on both sides to clamp two curved metal sheets, and then performs local bunching and stretching on the clamped folded and fried core yarn under the traction of downstream equipment.
[0039] In an exemplary embodiment, Figure 1 As shown, during use, fiber 1 is unwound from a bobbin and passes through area detection sensor 3. The core yarn passes normally, and the covering process proceeds normally. If the core yarn folds or explodes, area detection sensor 3 detects the abnormality and generates tension, which is transmitted to pressure rod 4. Pressure rod 4 compresses spring 5, which transmits the tension to draft tensioner 6. Draft tensioner 6 generates tension to stretch and bundle the abnormal core yarn, restoring the fiber to a straight state.
[0040] The device of the present application can detect the state of the fed core yarn through the area detection sensor 3, thereby ensuring the normal operation of the coating structure. The area detection sensor 3 detects the area change of the core yarn (folding, bursting), and applies tension to the drafting and bunching device to make the fibers reach a straightened and bunched state, thereby improving the efficiency of the coating structure spinning and the quality of the yarn. The device of the present application also allows for adjustment according to the actual use environment and needs to adapt to different spinning needs and achieve precise drafting and bunching. This design not only improves spinning efficiency, but also helps to reduce energy consumption and maintenance costs.
[0041] To sum up, the spinning drafting sensor device based on the coated structure of the present application can effectively capture the changes in the core yarn area, and the drafting bundler effectively performs drafting technology on the folded and fried core yarn, effectively solving the problems of yarn knots and breakage of the coated structure yarn, thereby making its application in the field of spinning processing and textile machinery more advantageous.
[0042] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above examples is only intended to help understand the method and core concept of this application. At the same time, for those skilled in the art, based on the concept of this application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
