Description

Technical Field

[0001] The patent of the present invention relates to a high-mix combing device in a non-woven fabric machine, specifically to a structure suitable for a high-mix combing machine for preventing wallboard flowers from forming at both ends of the cylinder. Background Art

[0002] A significant factor affecting the speed and output of a carding machine is wall shavings. There's a gap between the two ends of the carding rollers and the wallboards. The flying fibers generated during carding, especially those near the roller ends, naturally find their way into the gaps, creating wall shavings. Repeated friction between the high-speed rotating rollers and the stationary wallboards causes the wall shavings to form hard, hard, and dirty strips. When the wall shavings accumulate to a certain level and aren't cleaned promptly, two destructive phenomena can occur: First, they can fall into the fiber web being carded, contaminating the web surface as it exits, creating defects and reducing the web's yield; second, they can't escape the gaps. As the wall shavings become more and more stuck, friction between the rollers and the wallboards increases, causing the rollers to stop rotating and resulting in production accidents. The higher the carding machine speed and output, the more wall shavings there are.

[0003] At present, some carding machines use a positive pressure blowing method dominated by blocking and sealing to deal with wallboard flowers. That is, they use an additional blowing system between the wallboard and the cylinder roller to create a slight positive pressure to prevent wallboard flowers. The specific principle is as follows:

[0004] like Figure 4 、 Figure 5 、 Figure 6 As shown, an annular sealing disk 29 is installed on the back of the cylinder circular wall plate 30; a cylinder plug 37 is embedded in the interior of the cylinder roller body 26 and welded to the cylinder roller body 26 as a whole; a sealing plate 38 made of thin iron sheet is installed on the outside of the plug, and an air flow channel 40 is formed between the sealing plate and the annular sealing disk; a 1mm slit 42 is provided between the annular sealing disk and the inner circle of the cylinder roller body; a 3mm slit 43 is provided between the inner side surface of the cylinder circular wall plate 30 and the end face of the cylinder roller body 26; the blowing air flows into the air flow channel 40 through the air inlet 35 on the cylinder circular wall plate 30 and the air cavity 41 in the middle of the annular sealing disk; the pressure is increased at the slit 42, and finally a positive pressure is formed at the slit 43 to prevent the formation of cylinder wall plate flowers.

[0005] The disadvantages of this structure are: when the shaft head blows air, when the airflow flows from the airflow channel 40 to the slit 42, the slit is designed in the axial direction, with a width of only 1 mm, and the channel through which the airflow passes is at two right angles. The air pressure is suddenly stopped here, resulting in a large loss, and the airflow that can reach the radial slit 43 that really plays a role in preventing wallboard flowers is far from enough; and when this structure is used on a high-mix carding machine, the linear speed of the high-mix roller is higher than that of the cylinder. Due to the strong centrifugal force, the flying flowers generated at the shaft end can easily squeeze into the slit 43, and the anti-wallboard flower effect is poor. Summary of the Invention

[0006] The purpose of the present invention is to address the deficiencies in the above-mentioned prior art and to provide a structure suitable for a high-impurity carding machine for preventing wallboard flowers from forming at both ends of the cylinder. The present invention is different from the structure of the prior art that uses a positive pressure blowing method dominated by blocking and sealing to treat wallboard flowers. The present invention adopts a method that combines blocking and dredging, so that the blowing airflow passes through a process of pressurization-pressure relief-re-pressurization-reasonable release in the channel, and smoothly generates positive pressure in the narrow gap between the end of the cylinder and the circular wall panel, and provides an air suction port near the high-impurity roller on the cylinder circular wall panel to promptly suck away the flying flowers squeezed into the wall panel due to high impurities, so as to achieve the purpose of preventing wallboard flowers in high-speed high-impurity carding machines.

[0007] The purpose of the present invention can be achieved by the following technical measures:

[0008] The structure for preventing wall panel flowers from occurring at both ends of the cylinder includes a cylinder plug that is fixedly encapsulated at both ends of the cylinder roller body; an annular groove is processed on the end face of the cylinder plug close to the side of the cylinder circular wall plate, and the inner ring surface of the outer ring groove wall of the annular groove is a trumpet-shaped structure; an annular sealing disk is fixedly installed on the inner side surface of the cylinder circular wall plate, which is gap-fitted with the groove wall and the groove bottom of the annular groove; the fitting gap between the annular groove and the annular sealing disk constitutes an air flow channel with pressurization and uniform wind function; and a slit structure with gap fit is adopted between the end face of the outer ring groove wall of the annular groove of the cylinder plug and the fitting surface of the cylinder circular wall plate; a circular wall plate air inlet connected to the air flow channel is provided on the cylinder circular wall plate, and the circular wall plate air inlet is connected to the air source through an air guide tube; a suction port connected to the suction pipe is provided on the cylinder circular wall plate near the lower high impurity position to extract the fibers entering between the cylinder and the circular wall plate due to the high-speed rotation centrifugal force at the circumferential ends of the upper and lower high impurities.

[0009] The bottom of the annular groove of the cylinder plug described in the present invention is composed of a groove bottom sealing plate made of metal sheet installed in the annular groove by screws II; the annular space between the annular sealing disk and the cylinder shaft head is encapsulated with an annular metal sealing plate by screws I, which closes the hollow part in the middle of the annular sealing disk; the gap between the annular sealing disk, the metal sealing plate encapsulated on the inner side of the annular sealing disk and the bottom sealing plate of the annular groove of the cylinder plug constitutes a uniform air pressure channel with pressurization and uniform air flow functions, and the space between the inner wall surface of the cylinder circular wall plate, the outer circular surface of the annular sealing disk, and the trumpet-shaped inner wall surface of the outer ring groove wall of the annular groove together constitutes a uniform air flow channel for releasing pressure, and the width of the slit connecting the uniform air flow channel is 3mm~4mm. The airflow entering the air flow channel through the air inlet of the circular wall plate is pressurized by the uniform air pressure channel and then enters the uniform air channel. The airflow released by the uniform air flow channel is pressurized again in the slit, so that the slit between the matching surface of the cylinder end plug and the circular wall plate produces a uniform and moderate positive pressure airflow, thereby achieving the purpose of preventing the occurrence of wallboard flowers.

[0010] The present invention fixes cylinder plugs at both ends of the cylinder roller body by welding, the welding surface of the cylinder roller body (1) and the cylinder plug is located on the outer circumference, the outer cylindrical surface of the cylinder roller body and the cylinder plug forms the outer circumference of the cylinder, and edge strips are provided on the outer circumference of the cylinder plug, and the cylinder needle cloth covers the outer circumference of the cylinder roller body and the cylinder plug.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. In the present invention, the air flow channel of the air-blowing anti-wall panel flower device is redesigned. After the air flow is introduced into the cavity between the wall panel and the cylinder plug through the air guide tube on the wall panel, it passes through the pressurized uniform wind in the narrow cavity and comes to the relatively loose pressure relief channel. The pressure relief channel guides the air flow through two large obtuse angles, and smoothly introduces the air flow into the radial slit between the wall panel and the cylinder plug, thereby generating a uniform and appropriate positive pressure on the circumference of the cylinder end. The structure is reasonable, and the effect of preventing wall panel flowers is very obvious.

[0013] 2. Add a suction pipe on the circular wall plate to directly remove the fibers generated by high-speed rotation of the impurities and that cannot be removed by the positive pressure on the cylinder end face, to prevent them from further entering the cylinder end face.

[0014] In summary, the present invention employs a blowing method at the end of the carding machine cylinder. By employing the principle of pressurizing uniform airflow, releasing uniform airflow, and then repressurizing, this method creates a uniform and moderate positive pressure around the cylinder end surface. Furthermore, a suction duct is added to the circular wall panel to remove fibers generated by high-speed rotation and unable to be removed by the positive pressure on the cylinder end surface. This provides a double insurance policy, thoroughly and effectively preventing wallboard smearing on the cylinder end surface of the high-impact carding machine. BRIEF DESCRIPTION OF THE DRAWINGS
