Description

Technical Field

[0001] The present application relates to the technical field of cooling bellows, and in particular to a cooling bellows for an EVO ring-blowing device. Background Art

[0002] Energy conservation is increasingly important in filament yarn production. Currently, the company's polyester filament production utilizes the EvoQuench quenching system, which reduces quenching air usage by 80% compared to transverse quenching systems. The EvoQuench concept utilizes more efficient quenching air than transverse quenching systems, significantly reducing the energy used for cooling. However, during production, the radial quenching system was found to have design flaws, causing inconvenience in production operations and placing significant pressure on quality control.

[0003] First, the current bellows slot is shallow, and the diameter of the hole in the bellows cover is larger than the diameter of the wind tube. When replacing the wind tube, it is easy for the wind tube to tilt and cause air leakage. Therefore, every time the filter element is replaced, it is necessary to check and confirm repeatedly. Despite this, air leakage still occurs, which may cause broken wires or hairy wires at the least, or abnormal physical properties and dyeing at the worst, leading to major quality accidents.

[0004] Secondly, the bellows has no air leakage detection device, and air leakage of the bellows is detected by touch. The gaps in some corners are small and difficult to reach with hands, which may easily lead to missed detection. Air leakage during the spinning process will cause the product to have greater unevenness, poor dyeing, and poor differentiation of the yarn bundles.

[0005] Therefore, it is necessary to provide an EVO ring blowing device cooling bellows to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0034] like Figures 1 to 7 As shown, the present application provides a cooling wind box of an EVO ring blowing device, comprising a cooling wind box 1 and a blowing duct 2. A wind tube seat 3 is provided at the bottom of the cooling wind box 1, and a wind tube 31 is provided on the wind tube seat 3, and the wind tubes 31 are arranged in multiple groups at equal intervals along the length direction thereof. A top plate 11 is provided on the cooling wind box 1, and a first through hole 12 is opened on the top plate 11, and the first through hole 12 is opened in multiple groups, and the first through hole 12 corresponds to the wind tube 31;

[0035] A sealing member 13 is provided inside the first through hole 12 for sealing the gap between the first through hole 12 and the air cylinder 31;

[0036] A wind pressure detection component 5 is provided on one side of the cooling air box 1 .

[0037] In this embodiment, air is blown into the cooling air box 1 through the blowing duct 2, so that the spun yarn can be quickly cooled when passing through the inside of the wind tube 31 in the first through hole 12. The top of the wind tube 31 and the first through hole 12 of the top plate 11 are sealed by the sealing member 13 to prevent air leakage and avoid affecting the spinning cooling process.

[0038] The blowing duct 1 in this application has the same structure as that of the patent with publication number CN201553821U, and will not be described in detail here.

[0039] like Figures 3 to 6 As shown, the sealing member 13 includes a fixing ring 131 fixedly arranged inside the first through hole 12, and a sealing ring 132 is arranged inside the fixing ring 131. The sealing ring 132 is preferably made of rubber material. A groove 133 is formed at the upper end of the fixing ring 131.

[0040] A porous plate 4 is provided on the top of the top plate 11. A second through hole 41 is provided on the upper end of the porous plate 4. The second through holes 41 are provided in multiple groups. The second through holes 41 correspond to the first through holes 12. An extrusion ring 42 is provided inside the second through hole 41. The extrusion ring 42 is used to squeeze the fixing ring 131.

[0041] The thickness of the extrusion ring 42 is greater than the width of the groove 133 , and the bottom of the extrusion ring 42 is chamfered so that the bottom of the extrusion ring 42 can be inserted into the groove 133 .

[0042] In this embodiment, during installation, the wind tube seat 3 is inserted and fixed from the bottom of the cooling air box 1, so that the top of the wind tube 31 can be placed inside the fixed ring 131, and then the extrusion ring 42 at the lower end of the porous plate 4 is aligned with the groove 133 on the fixed ring 131 and pressed down, so that the extrusion ring 42 is squeezed into the groove 133, and the inner ring of the fixed ring 131 is deformed, so that the sealing ring 132 inside the fixed ring 131 is squeezed toward the outside of the wind tube 31, and the wind tube 31 is fixed and sealed at the same time, which can effectively prevent the wind tube 31 from shaking, and avoid air leakage and shaking from affecting the cooling of spinning.

[0043] like Figures 3 to 6 As shown, a first bolt 44 is provided at the upper end of the porous plate 4, and the first bolt 44 is threadedly connected to the top plate 11;

[0045] In this embodiment, the porous plate 4 is connected to the top plate 11 by a first bolt 44 so that it can be subsequently disassembled and replaced. The adaptation of the positioning column 43 and the positioning hole 111 can prevent the porous plate 4 from being offset when installed on the upper end of the top plate 11.

[0046] like Figure 2 As shown, the middle portion of the air duct 31 is made of a metal mesh material, and the cross section is wavy.

[0047] In this embodiment, since the middle part of the air tube 31 is made of metal mesh material and is wavy, it can make the cooling air cool the spinning more evenly and stably, and the rectification effect is greatly improved.

[0048] like Figure 7 As shown, the wind pressure detection assembly 5 includes a connecting pipe 51, one end of which is provided with a wind pressure sensing probe 52, and the connecting pipe 51 is provided with four groups of wind pressure sensing probes 52 at equal intervals along the axis direction of the wind pressure sensing probe 52. The wind pressure sensing probes 52 are made of nickel-plated metal and are oil-resistant and corrosion-resistant. The wind pressure sensing probes 52 are located inside the cooling air box 1, and one end of the connecting pipe 51 is provided with an alarm 54.

[0049] A mounting plate 53 is provided on the outside of the connecting pipe 51. A second bolt 531 is provided on one side of the mounting plate 53. The second bolt 531 is threadedly connected to the cooling air box 1.

[0050] The wind pressure detection component 5 also includes a control panel, a control module, an alarm indicator light, and a display module (not indicated in the figure). The control panel and the control module are installed inside the alarm 54, and the alarm indicator light and the display module are installed outside the alarm 54. The display module is preferably a display screen.

[0051] In this embodiment, the wind pressure inside the cooling air box 1 is detected by the wind pressure sensing probe 52, and the pressure signal is converted into an electrical signal. The real-time wind pressure is displayed by the alarm 54. The real-time wind pressure and the set wind pressure are interlocked. When the set value is exceeded, the alarm 54 will be activated, and the alarm indicator light and the alarm 54 will send a prompt signal. On-site employees can be discovered on site at the first time and respond quickly.
