Description

Technical Field

[0001] The utility model belongs to the technical field of flushable spunlace fabric production, and particularly relates to a lint detection device for flushable spunlace fabric. Background Art

[0002] Flushable spunlace fabric is also called biodegradable spunlace non-woven fabric. It is made by spraying high-pressure fine water flow onto one or more layers of fiber webs, causing the fibers to entangle with each other, thereby strengthening the fiber web and giving it a certain strength. The resulting fabric is a spunlace non-woven fabric.

[0003] During the spunlace production process, a fiber web is drawn from the surface to the bottom by high-pressure jets. Some fibers are ejected onto the support curtain and then rebound, entangled with each other, solidifying the fibers to form a nonwoven base fabric with a certain strength, or fiber web. However, if the fibers are not tightly entangled or the fibers themselves are not strong enough, lint will form. This lint on the spunlace can negatively impact the cleaning effect during use, resulting in incomplete cleaning and damage to the surface being cleaned. For example, when wiping precision electronic products, lint can affect the performance of the electronic products by becoming tiny obstacles that can affect the transmission of electronic signals or cause short circuits.

[0004] Currently, the existing method for detecting lint on flushable spunlace fabrics is to remove the fabric sample to be tested, wet the fabric (sample), apply a certain pressure, rub it on sandpaper, and then measure the weight of the lint remaining on the sandpaper to determine the lint loss of the flushable spunlace fabric (sample). However, this detection method can only detect a small area of ​​the fabric surface on the sample, and cannot detect the overall lint loss of the spunlace fabric during the production process. In addition, the above-mentioned existing methods for detecting lint loss of spunlace fabrics cannot detect lint loss during the production process of spunlace fabrics, and cannot monitor the lint loss of spunlace fabrics in real time during the production process. Utility Model Content

[0005] In order to solve the above technical problems, one of the purposes of the present invention is to provide a flushable spunlace fabric lint detection device, which can effectively detect the overall lint situation of the spunlace fabric during the production process, and can monitor the lint situation of the spunlace fabric during the production process in real time.

[0006] The utility model provides a device for detecting lint loss in flushable spunlace fabrics, which adopts the following technical solutions:

[0007] A device for detecting lint loss in spunlace fabrics, which can be flushed away, comprises an air compressor, a suction machine and a filter screen, wherein the air outlet end of the air compressor is connected to an air supply pipe, and the air supply pipe is provided with an air outlet at one end facing away from the air compressor, and the air outlet is located above the upper surface of the spunlace fabric that has been dried and is being transported, and the air suction port of the suction machine is connected to an exhaust pipe, and the exhaust pipe is provided with an air intake at the air suction end facing away from the suction machine, and the air intake is located below the upper surface of the spunlace fabric, and the air intake is arranged opposite to the air outlet, and the filter screen is arranged in the exhaust pipe; wherein the compressed air flow blown out from the air outlet passes through the opposite surface of the spunlace fabric, blows off the lint on the spunlace fabric, enters the exhaust pipe, and is intercepted by the filter screen.

[0008] Furthermore, the distance between the air outlet and the upper surface of the spunlace fabric is set to L1, and L1 satisfies the relationship of 0<L1<10mm.

[0009] Furthermore, the distance between the air intake port and the lower surface of the spunlace fabric is set to L2, and L2 satisfies the relationship of 0<L2<10mm.

[0010] Furthermore, it is characterized in that an air filter is provided in the air outlet for filtering the compressed air flow output by the air compressor.

[0011] Furthermore, the projected areas of the air outlet and the air intake on the spunlace fabric are equal.

[0012] Furthermore, the projected area of ​​the air outlet on the spunlace fabric covers the width of the spunlace fabric.

[0013] Furthermore, the projection area of ​​the air intake port on the spunlace fabric covers the width of the spunlace fabric.

[0014] Furthermore, the exhaust pipe includes a first pipe section and a second pipe section connected end to end, the first pipe section is connected to the exhaust end of the suction machine, and the second pipe section is connected to the air intake port. The first pipe section has a structure that is larger in the middle and smaller at both ends, and the outer wall of the filter is sealed and fixed to the inner wall of the first pipe section.

[0015] Furthermore, the air inlet and / or the air inlet is configured as a funnel-shaped structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the flushable spunlace fabric lint detection device of the present invention is in use, the air outlet on the air supply pipe is set above the upper surface of the spunlace fabric being conveyed, and the air intake of the exhaust pipe is set below the upper surface of the spunlace fabric being conveyed, and the air intake and air outlet are directly opposite. During the conveying process of the spunlace fabric, the compressed air flow generated by the air compressor is blown toward the upper surface of the spunlace fabric through the air outlet on the air supply pipe and then passes through the lower surface of the spunlace fabric, so that the compressed air flow carries away the lint that is not firmly entangled on the spunlace fabric. These lints enter the suction pipe from the lower surface of the spunlace fabric with the air flow, and are sucked away by the suction machine during the suction. The lint filtered on the filter screen is subsequently weighed and quantified to obtain the amount of lint lost by the spunlace fabric being produced and conveyed. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] The following describes various non-limiting embodiments of the present invention in detail. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0026] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0027] Reference Figure 1 、 Figure 2 A device for detecting lint loss of spunlace fabrics, which can be flushed away, includes an air compressor 2, a suction machine 1 and a filter 9.

[0028] Reference Figure 1 、 Figure 2 , wherein the air outlet end of the air compressor 2 is connected to an air supply pipe 3, and the air supply pipe 3 is provided with an air outlet 5 at one end facing away from the air compressor 2, and the air outlet 5 is located above the upper surface of the flushable spunlace fabric 11 that has been dried and is being transported, and the air suction port of the suction machine 1 is connected to an exhaust pipe 4, and the exhaust pipe 4 is provided with an air suction port 6 at the air suction end facing away from the suction machine 1, and the air suction port 6 is located below the upper surface of the flushable spunlace fabric 11, and the air suction port 6 is arranged opposite to the air outlet 5, and the filter 9 is arranged in the exhaust pipe 4; wherein the compressed air flow blown out from the air outlet 5 passes through the opposite surface of the flushable spunlace fabric 11, blows off the hair debris on the flushable spunlace fabric 11, enters the exhaust pipe 4, and is intercepted by the filter 9.

[0029] Reference Figure 1-Figure 3 The air outlet 5 has a funnel-shaped structure, which is beneficial to increasing the air outlet area of ​​the air outlet 5; the air intake 6 also has a funnel-shaped structure, which is beneficial to increasing the air intake area of ​​the air intake 6. The compressed air flow blown out of the air outlet 5 passes through the opposite surface of the spunlace fabric 11 and blows it off, carrying away the lint on the spunlace fabric 11. The air flow carrying the lint enters the suction machine 1 and is intercepted by the filter 9 into the suction machine 1. Specifically, the air compressor 2 is an air compressor for outputting air flow, and the suction machine 1 is an air extractor for inhaling the air flow carrying the lint.

[0030] In summary, it can be seen that when the flushable spunlace fabric lint detection device of the present invention is in use, the air outlet 5 on the air delivery pipe 3 is set above the upper surface of the flushable spunlace fabric 11 being transported after drying, and the air intake 6 of the exhaust pipe 4 is set below the upper surface of the flushable spunlace fabric 11 being transported, and the air intake 6 is made to face the air outlet 5. During the transportation of the flushable spunlace fabric 11, the compressed air flow generated by the operation of the air compressor 2 is blown to the upper surface of the flushable spunlace fabric 11 through the air outlet 5 on the air delivery pipe 3. The compressed air passes through the lower surface of the dispersible spunlace fabric 11, so that the compressed air flow takes away the hair debris that is not firmly entangled on the dispersible spunlace fabric 11. These hair debris enter the suction pipe from the lower surface of the dispersible spunlace fabric 11 with the air flow. Under the suction force of the suction machine 1, the air flow carrying the hair debris passes through the filter 9, and the hair debris is filtered and intercepted on the filter 9. The air flow is sucked away by the suction machine 1. Subsequently, the hair debris filtered on the filter 9 is weighed and quantified to obtain the value of the hair debris dropped by the dispersible spunlace fabric 11 being produced and transported.

[0031] Reference Figure 1-Figure 3 The distance between the air outlet 5 and the upper surface of the flushable spunlace fabric 11 is set to L1, and the relationship satisfied by L1 is 0<L1<10mm. In this embodiment, L1 is 5mm. Since the air flow blown out of the air outlet 5 directly hits the surface of the flushable spunlace fabric 11, and then removes the lint through the air flow, if L1 is too large, the external air will be brought into the surface of the flushable spunlace fabric 11, causing the flushable spunlace fabric 11 to be contaminated.

[0032] In other embodiments, the distance between the air outlet 5 and the upper surface of the flushable spunlace fabric 11 may also be 9 mm or 0.1 mm.

[0033] Reference Figure 1-Figure 3 The distance between the air intake port 6 and the lower surface of the dispersible spunlace fabric 11 is set to L2, and the relationship satisfied by L2 is 0<L2<10mm. In this embodiment, L2 is 5mm. Since the air intake port 6 sucks in the airflow passing through the dispersible spunlace fabric 11 through suction force, if L2 is too large, it will lead to a decrease in the suction force on the surface of the dispersible spunlace fabric 11, and the airflow carrying lint cannot be completely sucked in, resulting in errors in the detection results.

[0034] In other embodiments, the distance between the air intake 6 and the lower surface of the spunlace fabric 11 may also be 9 mm or 0.1 mm.

[0035] Reference Figure 1-Figure 3 An air filter 10 is provided in the air outlet 5. The air filter 10 is used to filter the compressed air flow output by the air compressor 2. The air output from the air outlet 5 by the air compressor is cleaned by the filtration of the air filter 10, thereby preventing the spunlace fabric 11 from being polluted by the output air.

[0036] Reference Figure 1-Figure 3 The projected area of ​​the air outlet 5 and the air inlet 6 on the spunlace fabric 11 is equal. Specifically, the projected area of ​​the air outlet 5 and the air inlet 6 on the spunlace fabric 11 is 100 cm 2 In this way, it is ensured that the airflow output from the air outlet 5 passes through the spunlace fabric 11, takes away the lint and can be completely sucked into the air intake 6, thereby ensuring the accuracy of the detection.

[0037] In other embodiments, the projected area of ​​the air outlet 5 and the air inlet 6 on the flushable spunlace fabric 11 can also be 120 cm 2 , it is set according to actual production needs and is not limited here.

[0038] Reference Figure 1-Figure 3 The projection area of ​​the air outlet 5 on the flushable spunlace fabric 11 covers the width of the flushable spunlace fabric 11. Specifically, the projection of the air outlet 5 on the flushable spunlace fabric 11 is a square with a side length of 10 cm. Thus, it can be ensured that when the flushable spunlace fabric 11 passes under the air outlet 5, all the fabrics on the width of the flushable spunlace fabric 11 are passed through by air and the lint on the fabric is taken away.

[0039] In other embodiments, the projection of the air outlet 5 on the flushable spunlace fabric 11 may also be a rectangle, which can be set according to actual production requirements and is not limited here.

[0040] Reference Figure 1-Figure 3 The projection area of ​​the air intake port 6 on the flushable spunlace fabric 11 covers the width of the flushable spunlace fabric 11. Specifically, the projection of the air intake port 6 on the flushable spunlace fabric 11 is a square with a side length of 10 cm. Thus, it can be ensured that when the flushable spunlace fabric 11 passes over the air intake port 6, the airflow with lint that passes through all the fabrics on the width of the flushable spunlace fabric 11 can be absorbed by the air intake port 6.

[0041] In other embodiments, the projection of the air inlet 6 on the flushable spunlace fabric 11 may also be a rectangle, which is not limited here.

[0042] Reference Figure 1-Figure 3 The exhaust pipe 4 includes a first pipe section 7 and a second pipe section 8 connected end to end. The first pipe section 7 is connected to the exhaust end of the suction machine 1, and the second pipe section 8 is connected to the air inlet 6. The first pipe section 7 is structured to be larger in the middle and smaller at both ends. The outer wall of the filter 9 is sealed and fixed to the inner wall of the first pipe section 7. Specifically, it can be understood that the airflow drawn into the air inlet 6 can only pass through the filter 9 before being drawn into the suction machine 1, and will not enter the gap between the filter 9 and the inner wall of the first pipe section 7 and be drawn into the suction machine 1, thereby improving the accuracy of detection.

[0043] Reference Figure 1-Figure 3 In addition, since the first pipe section 7 is a structure with small ends and a large middle, the filter screen 9 is fixed in the middle position of the first pipe section 7, which can store more filtered hair debris and avoid the need for manual repeated cleaning when there is too much hair debris.

[0044] Effect of the present invention: When the lint-dropping detection device for flushable spunlace fabric is in use, the air outlet 5 on the air delivery pipe 3 is arranged above the upper surface of the flushable spunlace fabric 11 being transported, and the air outlet 5 is located at a position of 0-10mm from the upper surface of the flushable spunlace fabric 11; the air intake 6 of the exhaust pipe 4 is arranged below the upper surface of the flushable spunlace fabric 11 being transported, and the air intake 6 is located at a position of 0-10mm from the lower surface of the flushable spunlace fabric 11, and the air intake 6 is directly opposite to the air outlet 5. During the transportation of the flushable spunlace fabric 11, the compressed air generated by the operation of the air compressor 2 passes through the air outlet 5 on the air delivery pipe 3 and is filtered by the air filter 10 on the air outlet 5. The airflow blows toward the upper surface of the dispersible spunlace fabric 11 and then passes through the lower surface of the dispersible spunlace fabric 11, so that the compressed air flow carries away the lint that is not firmly entangled on the dispersible spunlace fabric 11. These lints follow the airflow from the lower surface of the dispersible spunlace fabric 11 into the air intake port 6, and enter the second pipe section 8 from the air intake port 6, and then flow from the second pipe section 8 to the inner cavity of the first pipe section 7. Under the suction force of the suction machine 1, the airflow carrying lint is filtered by the filter screen 9 in the first pipe section 7 and then absorbed by the suction machine 1. The lint is filtered and intercepted on the filter screen 9 in the first pipe. Subsequently, the lint filtered on the filter screen 9 is weighed and quantified to obtain the value of the lint amount of the dispersible spunlace fabric 11 being produced and transported.
