Description

Technical Field

[0001] The present application relates to the technical field of water-based absorbing material manufacturing, and in particular to a flexible substrate surface modification groove and a water-based absorbing material manufacturing device. Background Art

[0002] Water-based absorbing materials are usually composed of a flexible substrate and an absorbing layer on the surface of the substrate. The film-forming property of the water-based absorbing material is not only related to its preparation process, but also closely related to the surface properties of the corresponding flexible substrate, such as the roughness, wettability and adsorption of the flexible substrate surface. Therefore, in order to make the flexible substrate have better surface properties and to prepare a water-based absorbing material with better film-forming properties, it is usually necessary to modify the surface of the flexible substrate before applying the absorbing slurry. Among them, the modification method of chemical reagent treatment has become one of the current mainstream surface modification methods due to its advantages of good modification effect and ease of implementation. However, due to the poor structural design of the current surface modification tank, it is difficult to take into account the modification of multiple flexible substrates with different surface modification requirements, especially for flexible substrates that require a longer modification treatment time. Utility Model Content

[0003] The purpose of this application is to provide a flexible substrate surface modification tank and a water-based absorbing material manufacturing device, which can take into account the modification of various flexible substrates with different surface modification requirements, and is particularly suitable for flexible substrates that require a longer modification treatment time.

[0004] The embodiment of the present application is implemented as follows:

[0005] In a first aspect, embodiments of the present application provide a flexible substrate surface modification tank, comprising a tank body, a transport unit, and a position adjustment unit. The tank body is configured to accommodate a chemical treatment liquid and has a feed side and a discharge side disposed opposite each other along a first direction. The transport unit includes an inner conveyor roller located within the tank body, the inner conveyor roller extending along a second direction and configured to transport the flexible substrate along the first direction. The position adjustment unit is located within the tank body and rotatably connected to both axial ends of the inner conveyor roller. The position adjustment unit is configured to adjust the position of the inner conveyor roller in the first direction and the vertical height thereof to adjust the feed angle of the flexible substrate and the immersion depth of the flexible substrate in the chemical treatment liquid.

[0006] In the above technical solution, a position adjustment unit is added to the body of the flexible substrate surface modification tank to cooperate with the transmission unit. Specifically, the position adjustment unit is disposed in the body and is rotatably connected to both axial ends of the inner conveyor roller to ensure normal conveyance of the flexible substrate via the transmission unit. The position adjustment unit is also configured to adjust the position of the inner conveyor roller in the first direction and the height in the vertical direction to adjust the feed angle of the flexible substrate and the immersion depth of the flexible substrate in the chemical treatment liquid, thereby achieving the modification of a variety of flexible substrates with different surface modification requirements. In addition, it should be emphasized that currently, for the surface modification of flexible substrates that require a long time, there are two main methods. One is to increase the amount of chemical treatment liquid to immerse more flexible substrates and thus extend the treatment time. However, this method has the problems of high cost, low safety factor, and high environmental pressure. The other method is to reduce the conveying rate of the flexible substrate so that the flexible substrate is immersed in the treatment liquid for a longer time. However, this method has the problem of low modification efficiency and is not suitable for industrial mass production. The modified trough with a specific structure provided in the embodiments of the present application utilizes a position adjustment unit to adjust the vertical height of the inner conveyor roller, thereby extending the surface modification time of the flexible substrate while maintaining the same amount of chemical treatment liquid and the flexible substrate conveying rate. In other words, the modified trough with a specific structure provided in the embodiments of the present application is particularly suitable for flexible substrates requiring a longer modification treatment time.

[0007] In some optional embodiments, the position adjustment unit includes two position adjustment modules relatively distributed along the second direction, and the two position adjustment modules each include a connected horizontal adjustment component and a vertical adjustment component, the horizontal adjustment component is connected to the corresponding inner wall of the trough body, and the vertical adjustment component is rotatably connected to the corresponding end of the inner conveying roller, the horizontal adjustment component is configured to be able to adjust the position of the vertical adjustment component in the first direction, and the vertical adjustment component is configured to be able to adjust the height of the inner conveying roller in the vertical direction.

This specific form of position adjustment unit has the advantages of simple structure and easy adjustment.

[0010] In the above technical solution, the horizontal adjustment component is configured in the form of a matching carrier plate and a driving block. Specifically, the carrier plate extends along a first direction and is connected to the corresponding inner wall of the trough body. In the second direction, one end of the driving block overlaps the top of the carrier plate, and the other end protrudes from the carrier plate and is connected to the vertical adjustment component. By adjusting the position of the driving block on the carrier plate, the position of the inner conveying roller in the horizontal direction can be adjusted. This specific structure of the horizontal adjustment component has the advantages of simple structure and easy adjustment.

[0011] In some optional embodiments, the horizontal adjustment assembly also includes a mounting plate and a locking member. In the vertical direction, the mounting plate is located above the supporting plate and is spaced relative to the supporting plate.

The locking member includes a screw, a limit block located at one end of the screw, and a nut corresponding to the screw. The screw passes through the through hole so that the mounting plate is located between the limit block and the nut. The bottom of the screw abuts against the top of the drive block so that the position of the drive block on the supporting plate is fixed.

[0012] In the above technical solution, the horizontal adjustment assembly also includes a mounting plate and a locking member. Specifically, the mounting plate and the supporting plate are relatively spaced and connected to the corresponding inner wall of the trough body. The mounting plate is provided with a through hole for cooperating with the locking member and extending along the first direction; the locking member includes a screw, a limit block located at one end of the screw, and a nut corresponding to the screw. The screw passes through the through hole so that the mounting plate is located between the limit block and the nut. The bottom of the screw abuts against the top of the driving block. The position of the screw in the first direction can be fixed by rotating the nut, and then its position can be fixed after the inner conveying roller is adjusted to the preset position, thereby improving the stability of the flexible substrate during the conveying process.

[0018] In the above technical solution, limiting rings are added at both axial ends of the inner conveying roller, and the inner circumferential walls of the two limiting rings and the outer circumferential wall of the inner conveying roller together form a limiting channel for passing the flexible substrate.

[0036] The following is a detailed description of a flexible substrate surface modification groove and a water-based absorbing material manufacturing device of the present application.

[0037] See Figure 1In a first aspect, an embodiment of the present application provides a flexible substrate surface modification tank 10, comprising a tank body 100, a transmission unit 200, and a position adjustment unit 300. The tank body 100 is used to contain a chemical treatment liquid, and the tank body 100 has a feed side and a discharge side arranged opposite to each other along a first direction a; the transmission unit 200 includes an inner conveying roller 210 located within the tank body 100, and the inner conveying roller 210 extends along a second direction b and is used to convey the flexible substrate along the first direction a; the position adjustment unit 300 is located within the tank body 100 and is rotatably connected to both axial ends of the inner conveying roller 210. The position adjustment unit 300 is configured to be able to adjust the position of the inner conveying roller 210 in the first direction a and the height in the vertical direction c, so as to adjust the feeding angle of the flexible substrate and the immersion depth of the flexible substrate in the chemical treatment liquid.

[0038] In the present application, a position adjustment unit 300 cooperating with the transmission unit 200 is added to the tank body 100 of the flexible substrate surface modification tank 10. Specifically, the position adjustment unit 300 is arranged in the tank body 100 and is rotatably connected to the axial ends of the inner conveying roller 210 so as to normally convey the flexible substrate through the transmission unit 200. In addition, the position adjustment unit 300 is also configured to be able to adjust the position of the inner conveying roller 210 in the first direction a and the height in the vertical direction c to adjust the feeding angle of the flexible substrate and the immersion depth in the chemical treatment liquid, thereby taking into account the modification of various flexible substrates with different surface modification requirements. In addition, it should be emphasized that, at present, there are two main means for surface modification of flexible substrates that require a long time. One is to increase the amount of chemical treatment liquid so that more flexible substrates can be immersed, thereby extending the treatment time. However, this method has problems such as high cost, low safety factor, and greater environmental pressure; the other means is to reduce the conveying rate of the flexible substrate so that the flexible substrate is immersed in the treatment liquid for a longer time. However, this method has the problem of low modification efficiency and is difficult to apply to industrial mass production. The modification tank of a specific structure provided in the embodiment of the present application adjusts the height of the inner conveying roller 210 in the vertical direction c through the position adjustment unit 300, so that the surface modification time of the flexible substrate can be extended while the amount of chemical treatment liquid and the conveying rate of the flexible substrate remain unchanged. In other words, the modification tank of a specific structure provided in the embodiment of the present application is particularly suitable for flexible substrates that require a longer modification treatment time.

[0039] It should be noted that, in addition to the inner conveying roller 210, the transmission unit 200 also includes an outer conveying roller located outside the trough body 100, so that the normal conveyance of the flexible substrate can be achieved through the cooperation of the inner and outer conveying rollers; wherein, the specific matching method of the inner and outer conveying rollers is not limited and can be adaptively adjusted according to actual needs.

[0040] It should be noted that, taking the rectangular parallelepiped trough body 100 as an example, the length direction of the trough body 100 is the first direction a, and the width direction of the trough body 100 is the second direction b.

[0041] It should be noted that the specific form of the position adjustment unit 300 is not limited, as long as it has the corresponding function, it can be set according to conventional options in the field.

[0042] See Figure 1 As an example, the position adjustment unit 300 includes two position adjustment modules 310 relatively distributed along the second direction b, and the two position adjustment modules 310 each include a connected horizontal adjustment component 311 and a vertical adjustment component 312. The horizontal adjustment component 311 is connected to the corresponding inner wall of the trough body 100, and the vertical adjustment component 312 is rotatably connected to the corresponding end of the inner conveying roller 210. The horizontal adjustment component 311 is configured to be able to adjust the position of the vertical adjustment component 312 in the first direction a, and the vertical adjustment component 312 is configured to be able to adjust the height of the inner conveying roller 210 in the vertical direction c.

[0043] In this embodiment, the position adjustment unit 300 is configured as two position adjustment modules 310 arranged relative to each other along the second direction b. Specifically, each position adjustment module 310 includes a connected horizontal adjustment component 311 and a vertical adjustment component 312. The horizontal adjustment component 311 is connected to the corresponding inner wall of the trough body 100 and is used to adjust the position of the vertical adjustment component 312 in the first direction a, thereby adjusting the position of the inner conveyor roller 210 in the first direction a. The vertical adjustment component 312 is rotatably connected to the corresponding end of the inner conveyor roller 210 and is used to adjust the height of the inner conveyor roller 210 in the vertical direction c without affecting the normal conveying function of the flexible substrate. This specific form of position adjustment unit 300 has the advantages of simple structure and easy adjustment.

[0044] See Figure 1 As an example, the horizontal adjustment component 311 includes a supporting plate 3111 and a driving block 3112. The supporting plate 3111 extends along the first direction a and is connected to the corresponding inner wall of the trough body 100. In the second direction b, one end of the driving block 3112 is overlapped on the top of the supporting plate 3111, and the other end protrudes from the supporting plate 3111 and is connected to the vertical adjustment component 312.

[0045] In this embodiment, the horizontal adjustment component 311 is configured to be in the form of a matching support plate 3111 and a driving block 3112. Specifically, the support plate 3111 extends along the first direction a and is connected to the corresponding inner wall of the trough body 100. In the second direction b, one end of the driving block 3112 is overlapped on the top of the support plate 3111, and the other end protrudes from the support plate 3111 and is connected to the vertical adjustment component 312. By adjusting the position of the driving block 3112 on the support plate 3111, the position of the inner conveying roller 210 in the horizontal direction can be adjusted. The horizontal adjustment component 311 of this specific structure has the advantages of simple structure and easy adjustment.

[0046] See Figure 2 and Figure 3 As an example, the horizontal adjustment assembly 311 also includes a mounting plate 3113 and a locking member 3114. In the vertical direction c, the mounting plate 3113 is located above the supporting plate 3111 and is spaced relative to the supporting plate 3111. The mounting plate 3113 is connected to the corresponding inner wall of the trough body 100. The mounting plate 3113 is provided with a through hole that passes through the mounting plate 3113 and extends along the first direction a. The locking member 3114 includes a screw 3114a, a limit block 3114b located at one end of the screw 3114a, and a nut 3114c corresponding to the screw 3114a. The screw 3114a passes through the through hole so that the mounting plate 3113 is located between the limit block 3114b and the nut 3114c. The bottom of the screw 3114a abuts against the top of the driving block 3112 so that the position of the driving block 3112 on the supporting plate 3111 is fixed.

[0047] When the cam 3114 is in the unlocked position, the locking member 3114 is unlocked and the locking member 3114 is unlocked.

[0048] See Figure 2As an example, a limiting groove (not shown in the figure) corresponding to the screw 3114a is opened on the top of the driving block 3112, and the bottom of the screw 3114a extends into the limiting groove and abuts against the bottom wall of the limiting groove.

[0049] In this embodiment, a limiting groove is opened on the top of the driving block 3112, and the bottom of the screw 3114a is extended into the limiting groove and abuts against the bottom wall so that the two form an interference fit, which has the advantage of higher fixing stability.

[0050] As an example, the top of the mounting plate 3113 further includes a scale extending along the first direction a.

[0051] In this embodiment, a scale is added to the top of the mounting plate 3113 to improve the accuracy of the driving block 3112 during the adjustment process.

[0052] See Figure 2 As an example, the vertical adjustment assembly 312 includes a vertically arranged rod body 3121, the rod body 3121 includes a threaded section 3121a located at the top and a connecting section 3121b located at the bottom, the driving block 3112 is provided with a screw hole corresponding to the threaded section 3121a (not shown in the figure), and the lower end of the connecting section 3121b is rotatably connected to the corresponding end of the inner conveying roller 210.

[0053] In this embodiment, the vertical adjustment component 312 includes a vertically arranged rod body 3121, specifically, the rod body 3121 includes a threaded section 3121a located at the top and a connecting section 3121b located at the bottom, wherein the threaded section 3121a is threadedly engaged with the screw hole provided in the driving block 3112, and the lower end of the connecting section 3121b is rotatably connected to the corresponding end of the inner conveying roller 210, that is, the height of the inner conveying roller 210 in the vertical direction c is adjusted by threaded engagement, which has the advantages of simple structure and easy adjustment.

[0054] It should be noted that the manner in which the lower end of the connecting section 3121 b is rotatably connected to the corresponding end of the inner conveying roller 210 is not limited, and for example, they may be connected via a bearing.

[0055] See Figure 4 As an example, the outer peripheral walls at both axial ends of the inner conveying roller 210 are further provided with limiting rings 220. In the axial direction of the inner conveying roller 210, the inner peripheral walls of the two limiting rings 220 and the outer peripheral wall of the inner conveying roller 210 are combined to form a limiting channel 230 for passing the flexible substrate.

[0056] In this embodiment, limiting rings 220 are additionally provided at both axial ends of the inner conveying roller 210. The inner circumferential walls of the two limiting rings 220 and the outer circumferential wall of the inner conveying roller 210 together form a limiting channel 230 for passing the flexible substrate. The inner conveying roller 210 with this specific structure can reduce the risk of the flexible substrate being deflected during the conveying process, thereby improving the conveying stability of the flexible substrate.

[0057] See Figure 4 As an example, a heat exchange chamber 110 is provided in the tank wall of the tank body 100 , the liquid inlet 111 of the heat exchange chamber 110 is located below the liquid outlet 112 , and the liquid inlet 111 and the liquid outlet 112 are located on the same side of the tank body 100 .

[0058] In this embodiment, a heat exchange chamber 110 is provided in the wall of the tank body 100, that is, a jacketed tank body 100 is adopted, and the liquid inlet 111 is arranged below the liquid outlet 112, which can achieve a better heat exchange effect, so that the temperature in the tank body 100 can be controlled within a preset range through the heat exchange medium, thereby achieving a better surface modification effect; in addition, the liquid inlet 111 and the liquid outlet 112 are both arranged on the same side of the tank body 100, which also has the advantage of being easy to operate.

[0059] As an example, a plurality of inner conveying rollers 210 and a plurality of position adjustment units 300 are provided, and the plurality of inner conveying rollers 210 and the plurality of position adjustment units 300 correspond to each other one by one and are spaced apart along the first direction a.

[0060] In this embodiment, multiple inner conveying rollers 210 and position adjustment units 300 are provided and correspond one to one, and the multiple inner conveying rollers 210 and the multiple position adjustment units 300 are spaced apart along the first direction a, which can more flexibly adjust the surface treatment time of the flexible substrate in the chemical treatment liquid; specifically, for example, when two inner conveying rollers 210 are provided, in order to adjust the surface treatment time, in addition to adjusting the position of the inner conveying roller 210 in the vertical direction c, it can also be achieved by adjusting the spacing between the two inner conveying rollers 210; for example, when three inner conveying rollers 210 are provided, in order to adjust the surface treatment time, in addition to adjusting the position of the inner conveying roller 210 in the vertical direction c and the spacing between the two inner conveying rollers 210, it can also be achieved by adjusting the relative positions of the three inner conveying rollers 210 in the vertical direction c, so as to achieve the effect by changing the conveying route of the flexible substrate.

[0061] It should be noted that any structural or functional units not specifically described or limited in the flexible substrate surface modification tank 10 may be configured according to conventional selections in the art.

[0062] In a second aspect, an embodiment of the present application provides an apparatus for manufacturing a water-based absorbing material, comprising a flexible substrate surface modification tank 10 as provided in the embodiment of the first aspect, a coater (for coating an absorbing slurry on the surface of the modified flexible substrate) and a drying oven (for curing the absorbing slurry to form an absorbing layer) arranged in sequence along the conveying direction of the flexible substrate.

[0064] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible.
