Description

Technical Field

[0001] This utility model relates to a voltage stabilization system, and more particularly to a voltage stabilization system suitable for vortex spinning process, belonging to the field of vortex spinning technology. Background Technology

[0002] Among new spinning technologies, vortex spinning, as the third generation of spinning methods developed after rotor spinning and self-twist spinning, has become a strategic direction for the transformation and upgrading of the modern spinning industry due to its advantages such as high speed and high output, stable quality and full-process automation.

[0003] In vortex spinning, compressed air is used as the power source for yarn formation. High-speed rotating compressed air separates, twists, and forms the fibers into yarn. Therefore, strict requirements are placed on the pressure of the compressed air. If the compressed air pressure is too low, the fibers will not be twisted sufficiently, resulting in increased yarn hairiness and a higher breakage rate. If the compressed air pressure is too high, the yarn strength will decrease, the fibers will be overstretched, and the yarn will become uneven.

[0004] The compressed air intake method is mostly a one-way double-sided intake at the head of the machine (such as the Rieter J26 vortex spinning machine), with the air gradually flowing from the left and right sides of the head to the tail. However, this method is difficult to guarantee the stability of the compressed air in each position of the machine, that is, the pressure is not stable. As a result, the pressure in the rear section of the machine will not meet the process pressure requirements, which will lead to a decrease in yarn quality and machine efficiency in the latter half of the machine.

[0005] Currently, to ensure the quality of yarn produced in the latter half of the machine meets the standards, the air compressor unit is generally added to ensure the compressed air output pressure, thereby increasing the air supply pressure to meet the pressure requirements of the latter half of the machine process. However, this method may cause excessive pressure in the spinning process, resulting in fluctuations in the yarn quality and affecting the machine efficiency. Furthermore, this method also increases the load on the air compressor unit, reduces the operating efficiency of the air compressor, increases energy costs, and affects economic benefits.

[0006] Although the existing technology "CN113215692A airflow spinning machine" provides an airflow spinning machine that does not require the air purification filter to be made larger and can reduce the pressure loss caused by the air purification filter, it is a single-sided air supply machine, which has uneven air supply and reduced end pressure, thus failing to guarantee yarn quality.

[0007] Therefore, ensuring stable compressed air pressure in the vortex spinning process to achieve stable yarn quality is an urgent technical problem to be solved. Summary of the Invention

[0008] To address the problems of unstable compressed air pressure from the head to the tail of a vortex spinning machine, which leads to poor and unstable yarn quality, as well as high energy consumption and low efficiency, a pressure stabilization system suitable for vortex spinning is proposed. In this technical solution, by specifically arranging the air supply pipes and valves, the pressure of the compressed air from the head to the tail of the vortex spinning machine is stabilized, thereby ensuring yarn quality, improving production efficiency, and reducing production costs.

[0009] To achieve the above technical objectives, the following technical solution is proposed:

[0010] A pressure stabilizing system suitable for vortex spinning process includes a main air supply pipeline and a pressure stabilizing unit connected to the main air supply pipeline. The pressure stabilizing unit includes a branch air supply pipeline I and a branch air supply pipeline II. One end of the branch air supply pipeline I is connected to the main air supply pipeline, and the other end of the branch air supply pipeline I is connected to one side of the tail of the vortex spinning machine through a first branch air supply pipeline I. The other end of the branch air supply pipeline I is also connected to the other side of the tail of the vortex spinning machine through a second branch air supply pipeline I.

[0011] One end of the gas supply branch pipe II is connected to the main gas supply pipe, and the other end of the gas supply branch pipe II is connected to one side of the vortex spinning machine head through the first gas supply branch pipe II. The other end of the gas supply branch pipe II is also connected to the other side of the vortex spinning machine head through the second gas supply branch pipe II.

[0012] The air supply branch pipe I, the first air supply branch pipe I, the second air supply branch pipe I, the air supply branch pipe II, the first air supply branch pipe II, and the second air supply branch pipe II form a continuous passage for stabilizing the compressed air pressure inside the vortex spinning machine.

[0013] Furthermore, there are at least two voltage stabilizing units, each connected to the main gas supply line. The number of voltage stabilizing units corresponds to the number of vortex spinning machines.

[0014] Furthermore, the gas supply branch pipe I, the first gas supply branch pipe I, and the second gas supply branch pipe I are connected by a tee I.

[0015] Furthermore, a pressure regulating valve I, a first filter I, and a second filter I are sequentially arranged on the gas supply branch pipe I.

[0016] Furthermore, the first filter I has an accuracy of 4-6µm, the filters I-II have an accuracy of 2-3µm, the second filter I is located behind the station of the first filter I, and the first filter I is located behind the station of the pressure regulating valve I.

[0017] Furthermore, the first gas supply branch pipe I is connected to the gas pipe of the right-side machine via a metal flexible hose I, and the second gas supply branch pipe I is connected to the gas pipe of the left-side machine via a metal flexible hose II. The installation of metal flexible hoses I and II facilitates the connection and arrangement of the pipelines.

[0018] Furthermore, the gas supply branch pipe II, the first gas supply branch pipe II, and the second gas supply branch pipe II are connected by a tee II.

[0019] Furthermore, a pressure regulating valve II, a first filter II, and a second filter II are sequentially arranged on the gas supply branch pipe II.

[0020] Furthermore, the first filter II has an accuracy of 4-6µm, the filter II-II has an accuracy of 2-3µm, the second filter II is located behind the station of the first filter II, and the first filter II is located behind the station of the pressure regulating valve I.

[0021] Furthermore, the first gas supply branch pipe II is connected to the gas pipe of the right machine, and the second gas supply branch pipe II is connected to the gas pipe of the left machine.

[0022] Among them, the number and specific location of the control valves (such as pressure regulating valves) and filters involved can be flexibly adjusted according to the length of the gas supply branch pipeline and to facilitate the shutdown of other machines during subsequent maintenance, so as to meet actual needs and adapt to different environments.

[0023] In this technical solution, the positional relationships involved, such as "rear side of the workstation", "one end", "the other end", "between", "side", "near", "end", "front side of the workstation", "upper", "inner side", "inner", "outer", and "external", are defined according to the actual usage conditions and are conventional terms in this technical field, as well as conventional terms used by those skilled in the art in actual use.

[0024] The beneficial technical effects of adopting this technical solution are as follows:

[0025] The utility model ensures stable compressed air pressure from the head to the tail of the vortex spinning machine by specifically arranging the air supply pipes and valves, thereby ensuring yarn quality, improving production efficiency, and reducing production costs.

[0026] This invention features dual-end air intake. An air supply branch pipe I is added at the tail end of the machine. One end of branch pipe I is connected to the main air supply pipe, and the other end is connected to one side of the tail end of the vortex spinning machine via a first air supply branch pipe I, and the other end is also connected to the other side of the tail end of the vortex spinning machine via a second air supply branch pipe I. At the head end, an air supply branch pipe II is added. One end of branch pipe II is connected to the main air supply pipe, and the other end is connected to one side of the head end of the vortex spinning machine via a first air supply branch pipe II, and the other end is also connected to the other side of the head end of the vortex spinning machine via a second air supply branch pipe II. This small-pipe pressure compensation method controls the compressed air pressure from the head to the tail end (front, middle, and rear) of the machine. Simultaneously, compressed air flows from both the head and tail end towards the middle, providing bidirectional air supply, shortening the compressed air flow path, and reducing the pressure drop problem at the end caused by unilateral air supply. The spinning unit in the middle area of ​​the vortex spinning machine is balanced by air supply from both ends, resulting in a more stable air pressure distribution and ultimately improving the consistency of product quality.

[0027] Furthermore, the installation of the first filter I, the second filter I, the first filter II, and the second filter II further ensures that the compressed air is clean and improves the stability of the vortex spinning process. Attached Figure Description

[0033] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0034] Example 1

[0035] A pressure stabilizing system suitable for vortex spinning process includes a main air supply pipe 1 and a pressure stabilizing unit connected to the main air supply pipe 1. The pressure stabilizing unit includes a branch air supply pipe I2 and a branch air supply pipe II3. One end of the branch air supply pipe I2 is connected to the main air supply pipe 1, and the other end of the branch air supply pipe I2 is connected to one side of the tail of the vortex spinning machine 5 through a first branch air supply pipe I4. The other end of the branch air supply pipe I2 is also connected to the other side of the tail of the vortex spinning machine 5 through a second branch air supply pipe I6 (e.g., ...). Figure 1-2 (as shown)

[0036] One end of the gas supply branch pipe II3 is connected to the main gas supply pipe 1, and the other end of the gas supply branch pipe II3 is connected to one side of the head of the vortex spinning machine 5 through the first gas supply branch pipe II7. The other end of the gas supply branch pipe II3 is also connected to the other side of the head of the vortex spinning machine 5 through the second gas supply branch pipe II8.

[0037] like Figure 3-4 As shown, the air supply branch pipes I2, I4, I6, II3, II7, and II8 form a continuous passage for stabilizing compressed air pressure within the vortex spinning machine 5. This uses a small-pipe pressure supplement method to ensure compressed air pressure from the machine head to the tail (front, middle, and rear). Simultaneously, compressed air flows bidirectionally from both the machine head and tail towards the center, shortening the airflow path and reducing the pressure drop at the end caused by unilateral air supply. The spinning unit in the middle area of ​​the vortex spinning machine is balanced by air supply from both ends, resulting in a more stable air pressure distribution and ultimately improving product quality consistency.

[0038] The invention modifies the existing "one-way, two-sided air supply method" for compressed air to a "two-way, two-sided air supply method," allowing compressed air to flow simultaneously from both the head and tail of the machine towards the middle, thus avoiding problems such as pressure differential and insufficient pressure at the rear due to unidirectional flow. Furthermore, pressure monitoring (pressure sensors) can be installed at the head, middle, and tail of the machine to monitor the compressed air pressure in real time, and supplementary pressure can be achieved through supply branch pipes, ensuring the stability of the compressed air supply and effectively reducing production costs.

[0039] Example 2

[0040] Based on Example 1, this example further defines the voltage regulator unit, and the technical solution is further explained in this example.

[0041] There are at least two pressure stabilizing units, both connected to the main gas supply line. The number of pressure stabilizing units can correspond to the number of vortex spinning machines.

[0042] Example 3

[0043] Based on Examples 1-2, this example further defines the gas supply branch pipe I2, the first gas supply branch pipe I4, and the second gas supply branch pipe I6, and provides further explanation of this technical solution.

[0044] Gas supply branch pipe I2, first gas supply branch pipe I4 and second gas supply branch pipe I6 are connected by tee I9.

[0045] Among them, the gas supply branch pipe I2 is sequentially equipped with a pressure regulating valve I10, a first filter I11, and a second filter I12.

[0046] The first filter I11 has a precision of 4-6µm, and filters I-II have a precision of 2-3µm. The second filter I12 is located behind the station of the first filter I11, which is located behind the station of the pressure regulating valve I10. The specific arrangement of the pressure regulating valve I10, the first filter I11, and the second filter I12 further ensures the cleanliness of the compressed air and improves the stability of the vortex spinning process. Specifically, the first filter I11 and the second filter I12 filter out impurities such as oil particles in the compressed air before delivering it to the machine head. More specifically, the compressed air first passes through the first filter I11 to pre-filter out oil, small particles, and other impurities, and then the second filter I12 finely filters out the remaining small impurities before finally being introduced into the machine through the first air supply branch pipe I4 and the second air supply branch pipe I6, thus forming a bidirectional, double-sided air supply.

[0047] In addition, the first gas supply branch pipe I4 is connected to the right-side machine air pipe 19 via a metal flexible hose I13, and the second gas supply branch pipe I6 is connected to the left-side machine air pipe 20 via a metal flexible hose II14. The installation of the metal flexible hoses I13 and II14 facilitates the connection and arrangement of the pipelines.

[0048] Example 4

[0049] Based on embodiments 1-3, this embodiment further defines the gas supply branch pipe I2, the first gas supply branch pipe I4, and the second gas supply branch pipe I6, and further explains the technical solution.

[0050] Gas supply branch pipe II3, first gas supply branch pipe II7 and second gas supply branch pipe II8 are connected by tee I9.

[0051] Among them, the gas supply branch pipe II3 is sequentially equipped with a pressure regulating valve II16, a first filter II17, and a second filter II18.

[0052] The first filter II17 has a precision of 4-6µm, and filter II-II has a precision of 2-3µm. The second filter II18 is located behind the station of the first filter II17, which is located behind the station of the pressure regulating valve I10. The specific arrangement of the pressure regulating valve II16, the first filter II17, and the second filter II18 further ensures the cleanliness of the compressed air and improves the stability of the vortex spinning process. Specifically, the first filter II17 and the second filter II18 filter out impurities such as oil particles from the compressed air before delivering it to the tail end of the machine. More specifically, the compressed air first passes through the first filter II17 to pre-filter out oil, small particles, and other impurities, and then the second filter II18 finely filters out the remaining small impurities before finally being introduced into the machine through the first air supply branch pipe II7 and the second air supply branch pipe II8, thus forming a bidirectional, double-sided air supply.

[0053] In addition, the first gas supply branch pipe II7 is connected to the right machine air pipe 19, and the second gas supply branch pipe II8 is connected to the left machine air pipe 20.

[0054] Example 5

[0055] Based on Examples 1-4, in order to further ensure the controllability of the pressure inside the vortex spinning machine, this pressure stabilization system also includes a PLC controller. Pressure sensors are installed at the head, middle, and tail of the machine. The pressure sensors, pressure regulating valve I10, and pressure regulating valve II16 are all connected to the PLC via electrical signals to collect the pressure inside the machine in real time and make corresponding adjustments to ensure the stability of the compressed air in the machine, thereby ensuring production efficiency and product quality.
