Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a sizing unwinding control system and a sizing machine. Background Technology

[0002] A sizing machine is a piece of equipment used in the textile industry to sizing warp yarns. By coating the yarn with sizing agents, its strength and abrasion resistance are improved, reducing yarn breaks during manufacturing and increasing weaving efficiency and fabric quality. Currently, sizing machines both domestically and internationally generally employ a multi-warp beam unified control method. This method uses tension rollers to detect the tension of the entire warp sheet after multiple warp beams are combined, and collectively regulates the frictional braking force of all warp beams to ensure a constant total tension of the yarn sheet. However, this control method has two main problems:

[0003] (1) This control method cannot individually control the unwinding tension of each warp beam, which inevitably leads to uneven tension of the yarn after control. Due to space limitations, it is not possible to install an independent tension sensor for each warp beam.

[0004] (2) During the unwinding process, the unwinding radius and moment of inertia of the warp shaft gradually decrease. When the warp shaft speed is faster before the end of unwinding, the response speed and control effect of this method will be weakened, and large tension fluctuations are very likely to occur.

[0005] To address the aforementioned issues, empirical measures such as manually adjusting the air pressure or artificially reducing the machine speed during the later stages of unwinding are often relied upon to attempt to maintain relative tension stability. However, these methods are not only cumbersome and inefficient, but also struggle to achieve high-precision tension control. Even after adjustment, errors and unevenness in the tension state are still unavoidable, which adversely affects the quality stability of the sizing, production efficiency, and the uniformity of the fabric's appearance during subsequent weaving processes.

[0006] Therefore, how to combine intelligent methods to propose a new system that can effectively improve the accuracy and stability of unwinding tension control has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0007] Based on this, the purpose of this utility model is to provide a sizing unwinding control system and a sizing machine, which solves the problems of errors and cumbersome operation in existing manual control, and improves the accuracy and stability of the unwinding tension control of the sizing machine.

[0008] To achieve the above objectives, this utility model first provides a sizing unwinding control system 100, including: a warp beam module 110, a warp beam tension sensor module 120, a control module 130, a pneumatic module 140, and a proportional valve module 150, each module being connected to the control module 130.

[0009] The warp beam module 110 includes N warp beams, the through-shaft tension sensor module 120 includes N through-shaft tension sensors, and the proportional valve module 150 includes N proportional valves.

[0010] The through-beam tension sensor module 120 is matched with the warp beam module 110, and a through-beam tension sensor is equipped at the end of each warp beam. These sensors are responsible for monitoring the yarn tension of their respective warp beams in real time, ensuring the accuracy and timeliness of the data.

[0011] The control module 130, as the core of the system, is responsible for receiving real-time measurement data transmitted from the through-shaft tension sensor module 120 and processing this data through a built-in control algorithm. The processing result is transmitted to the air pressure module 140 in the form of a control signal to guide it in adjusting the air pressure.

[0012] The pneumatic module 140 responds to the tension requirements of each warp axis by providing pneumatic pressure according to the instructions of the control module 130.

[0013] The proportional valve module 150, serving as the actuator for air pressure regulation, includes a first proportional valve 151, a second proportional valve 152, a third proportional valve 153, and a fourth proportional valve 154. More proportional valves can be added depending on actual usage. Based on the instructions from the air pressure module 140, the proportional valve module 150 delivers precise air pressure adjustments to the corresponding warp beams. This process aims to adjust the braking torque of each warp beam, thereby achieving precise control of the yarn unwinding tension.

[0014] Specifically, the system's workflow is as follows: After system startup, each warp beam's through-beam tension sensor independently monitors its own yarn tension and transmits real-time data to the control module 130. The control module 130 processes this data according to a control algorithm, calculates the required air pressure adjustment for each warp beam, and transmits this information to the air pressure module 140. Subsequently, the air pressure module 140 delivers the precise air pressure adjustment to the corresponding warp beam through the proportional valve module 150 to adjust its braking torque, thereby achieving precise control of the yarn unwinding tension. From the start to the end of warp beam unwinding, the through-beam tension sensors continuously monitor tension changes, and the system operates cyclically according to this workflow to ensure tension stability throughout the entire unwinding process.

[0015] Secondly, this utility model provides a sizing machine 300, including: an intelligent sizing unwinding control system module 310 and a sizing other combined control system module 320.

[0016] The intelligent sizing and unwinding control system module 310 includes a sizing and unwinding control system 100 and a first frame 311. The introduction of this system enables precise control of the tension of single-axis yarns, further ensuring the consistency of tension during the unwinding process of multi-axis yarns.

[0017] Furthermore, the corresponding frame serves to support and install various key components, such as the warp shaft module, the through-shaft tension sensor module, the pneumatic module, and the proportional valve module.

[0018] The other combined control system module 320 for sizing includes a sizing, drying and winding control system 322 and a second frame 321.

[0019] By organically integrating the control systems of other steps in the sizing process, the proposed module can further improve the overall sizing quality and production efficiency.

[0020] The beneficial effects of the utility model are:

[0021] By independently configuring through-beam tension sensors and proportional valves for each warp beam in the sizing unwinding zone, precise and independent control of the unwinding tension of each warp beam is achieved within a limited installation space. This improves the uniformity of unwinding tension on a single beam and the consistency of tension during multi-beam coordinated unwinding, thus ensuring the stability of sizing quality. Simultaneously, this solution effectively avoids errors introduced by manual adjustments, successfully resolving the tension unevenness and stability issues commonly found in multi-warp beam unified control methods, significantly improving production efficiency and automation levels. Furthermore, the system boasts high integration, seamlessly integrating with other functional modules of the sizing machine to achieve overall coordinated unwinding, further enhancing the overall performance and reliability of the equipment.

Detailed Implementation

[0026] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features described herein can be combined with each other.

[0027] Example 1

[0028] like Figure 1 As shown, an embodiment of the present invention provides a sizing and unwinding control system 100, including: a warp beam module 110, a through-beam tension sensor module 120, a control module 130, a pneumatic module 140, and a proportional valve module 150. This embodiment is illustrated using the example of the warp beam module 110 containing four warp beams.

[0029] The warp beam module 110 includes a first warp beam 111, a second warp beam 112, a third warp beam 113, and a fourth warp beam 114. The through-beam tension sensor module 120 correspondingly includes a first through-beam tension sensor 121, a second through-beam tension sensor 122, a third through-beam tension sensor 123, and a fourth through-beam tension sensor 124. These sensors are mounted on their respective warp beams to monitor the yarn tension of their respective warp beams in real time, ensuring the accuracy and timeliness of the data.

[0030] The control module 130, as the core of the system, is responsible for receiving real-time measurement data transmitted from the through-shaft tension sensor module 120 and processing this data through a built-in control algorithm (e.g., classic PID closed-loop tension control). The processing result is transmitted to the pneumatic module 140 in the form of a control signal. The pneumatic module 140 adjusts the pneumatic pressure accordingly based on the received control signal to respond to the tension requirements of each warp shaft.

[0031] The proportional valve module 150 includes a first proportional valve 151, a second proportional valve 152, a third proportional valve 153, and a fourth proportional valve 154. As the actuator for air pressure regulation, it delivers precise air pressure regulation amounts to the corresponding warp shafts according to the instructions from the air pressure module 140.

[0032] The workflow of System 100 is as follows: After System 100 starts, the through-beam tension sensors equipped with each warp beam independently monitor the tension of their respective yarns and transmit the real-time data to the control module 130. The control module 130 processes this data according to the control algorithm, calculates the required air pressure adjustment for each warp beam, and transmits this information to the air pressure module 140. The air pressure module 140 then delivers the precise air pressure adjustment to the corresponding warp beam through the proportional valve module 150 to adjust its braking torque, thereby achieving precise control of the yarn unwinding tension. From the start to the end of warp beam unwinding, the through-beam tension sensors continuously monitor tension changes, and the system operates cyclically according to this workflow to ensure tension stability throughout the entire unwinding process.

[0033] like Figure 2 As shown, the control process of the first warp beam 111 is as follows: First, the first through-shaft tension sensor transmits the real-time tension data of the first warp beam to the control module 130; then, the control module 130 processes the real-time tension data according to the control algorithm, calculates the required air pressure adjustment amount for the first warp beam 111, and transmits it to the air pressure module 140; subsequently, the air pressure module 140 transmits the precise air pressure adjustment amount to the braking cylinder of the first warp beam 111 through the first proportional valve 151, and adjusts the air pressure in the cylinder to achieve real-time adjustment of the braking torque of the first warp beam 111, thereby achieving precise control of the unwinding tension of the first warp beam 111.

[0034] Example 2:

[0035] like Figure 3 As shown, this embodiment provides a sizing machine 300, including: a sizing unwinding control system module 310 and a sizing other combined control system module 320.

[0036] The sizing unwinding control system module 310 includes the aforementioned sizing unwinding control system 100 and a first frame 311. Further, the first frame 311 serves to support and install various key components, such as the warp beam module 110, the through-beam tension sensor module 120, the pneumatic module 140, and the proportional valve module 150.

[0037] The other combined control system module 320 for sizing includes a second frame 321 and a sizing, drying and winding control system 322. The second frame 321 is used to support and install the various key components in the sizing, drying and winding control system 322.

[0038] By integrating the two modules mentioned above, the overall sizing machine can be re-unwinded in a coordinated manner, further improving the overall sizing quality and production efficiency.

[0039] The working principle of this utility model:

[0040] Specifically, the system's workflow is as follows: After system startup, each warp beam's through-beam tension sensor independently monitors its own yarn tension and transmits real-time data to the control module. The control module 130 processes this data according to a control algorithm, calculates the required air pressure adjustment for each warp beam, and transmits this information to the air pressure module 140. Subsequently, the air pressure module 140 delivers the precise air pressure adjustment to the corresponding warp beam through the proportional valve module 150 to adjust its braking torque, thereby achieving precise control of the yarn unwinding tension. From the start to the end of warp beam unwinding, the through-beam tension sensors continuously monitor tension changes, and the system operates cyclically according to this workflow to ensure tension stability throughout the entire unwinding process.

[0041] The control process of the first warp beam 111 is as follows: First, the first through-beam tension sensor transmits the real-time tension data of the first warp beam to the control module 130; then, the control module 130 processes the real-time tension data according to the control algorithm, calculates the required air pressure adjustment amount for the first warp beam 111, and transmits it to the air pressure module 140; subsequently, the air pressure module 140 transmits the precise air pressure adjustment amount to the first warp beam 111 through the first proportional valve 151, and adjusts its braking torque in real time, thereby achieving precise control of the unwinding tension of the first warp beam 111.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model, as well as some of the application examples, and are not intended to limit this utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
