Description

Technical Field

[0001] The present application relates to the technical field of panty liner surface cloth processing, and specifically discloses a panty liner surface cloth processing device. Background Art

[0002] The panty liner fabric refers to the outermost layer of the panty liner (such as sanitary pads, sports pads, etc.) that directly contacts the skin. Its main function is to provide comfort, leak-proofness and breathability.

[0003] The function of the panty liner cover is roughly as soft material to reduce friction on the skin, suitable for long-term use, avoid stuffiness, and reduce discomfort or bacterial growth caused by moisture;

[0004] Common materials for panty liner cover are: pure cotton, non-woven fabric and bamboo fiber;

[0005] The process of making pure cotton panty liner fabrics can generally include composite lamination, roll forming and slitting. The core process is: Roll forming: the composite material is compacted by rollers to control the thickness uniformity;

[0006] Chinese Patent Publication No. CN110725069B discloses a non-woven fiber web pressing device, comprising a carding machine cotton feed curtain pressing mechanism and a web laying machine web laying curtain pressing mechanism. The carding machine cotton feed curtain pressing mechanism is disposed on a carding machine cotton feed curtain roller support frame at one end of the carding machine facing the web laying machine and cooperates with the carding machine cotton feed curtain of the carding machine, while the web laying machine web laying curtain pressing mechanism is disposed on a web laying machine web laying curtain roller support frame at one end of the web laying machine facing the carding machine and cooperates with the web laying machine web laying curtain of the web laying machine. This prevents the non-woven fiber web from floating upward in the interface area between the carding machine and the web laying machine, and simultaneously compacts the non-woven fiber web, thereby increasing the web laying speed and enhancing the strength of the web layer laid out by the web laying machine, thereby improving the quality of the non-woven product.

[0007] Now there are the following problems:

[0008] During the roller compaction process, there is hard contact. The so-called hard contact means that after the roller determines the compaction size, it is hard contact when it first contacts the pure cotton of the composite layer. At this time, the height of the composite layer is higher than the height surface of the roller, and hard contact begins. This hard contact will cause the composite layer to split. Generally speaking, in order to avoid hard contact, the existing technology adopts to reduce the mobile contact when it first contacts the pure cotton of the composite layer, which is a "soft landing". However, this method will still cause certain quality problems with the pad surface cloth. In view of this, in order to improve this phenomenon, the present invention provides a pad surface cloth processing device to solve the above problems. Summary of the Invention

[0009] The purpose of the present invention is to improve the phenomenon that the composite layer is split due to hard contact in the roll-forming process of the traditional care face cloth.

[0010] In order to achieve the above object, the present invention provides the following basic scheme:

[0011] A device for processing sanitary pad surface cloth comprises a base, an arc frame detachably connected to the base, an electric rotating roller arranged based on the arc direction of the arc frame, an expandable pressure roller assembly arranged on the periphery of the electric rotating roller, and a negative pressure transport assembly arranged on the base and arranged along the length of the base for transporting a composite layer, wherein the distances between adjacent pressure roller assemblies and the surface of the base are different.

[0012] Furthermore, the base is a concave base, the negative pressure transport assembly is installed in a concave position of the concave base, a stabilizing column is provided at the bottom of the concave base, and the free end of the stabilizing column is fixed with a rubber anti-slip pad in contact with the ground.

[0013] Furthermore, the negative pressure transport component includes a transport part and a negative pressure part, the transport part has symmetrically arranged annular mounting grooves, a support frame for supporting the annular mounting grooves, a plurality of lateral movement areas arranged in the annular mounting grooves, an electric roller structure with a built-in motor installed in the lateral movement area, and a locking member for fixing the electric roller structure, and the negative pressure part is arranged between adjacent support frames.

[0014] Furthermore, the negative pressure part includes a plurality of suction holes opened on the base, a conduit for connecting the suction holes and an external negative pressure machine. After the negative pressure machine is connected to the conduit, the suction holes generate negative pressure.

[0015] Furthermore, the base is provided with a latch hole, and latches are correspondingly provided at both ends of the bottom of the arc-shaped frame, and the latches are connected to the latch holes by a snap connection.

[0016] Furthermore, the arc shape of the arc frame gradually becomes smaller along the movement direction of the negative pressure transport component.

[0017] Furthermore, the pressure roller assembly includes an inner frame fixed to the rotating outer ring of the electric rotating roller, a partition plate evenly fixed around the inner frame, a plurality of installation areas formed based on the partition plate, an inflatable airbag arranged in the installation area, and an expansion plate arranged at the expansion end of the inflatable airbag, and the expansion plate is arranged corresponding to the installation area.

[0018] Furthermore, the structure of the electric rotating roller is the same as that of the electric roller with a built-in motor, both of which adopt a built-in motor layout, and the pressure roller assembly is fixedly connected to the electric rotating roller.

[0019] Furthermore, the fixed end of the inflatable airbag is installed inside the installation area, and the expansion end of the inflatable airbag is fixed to the expansion plate. When the inflatable airbag is not inflated, the expansion plate is combined into a circle. After the inflatable airbag is inflated, the expansion plate expands outward along the expansion direction of the inflatable airbag.

[0020] The principle and effect of this solution are:

[0021] 1. Compared with the existing technology, this device adopts a design without a fixed card group. The composite layer can be directly placed on the negative pressure transport component for transportation. Because the negative pressure transport component adopts a negative pressure design, the negative pressure transport component has an adsorption effect on the composite layer based on the negative pressure design. Since the design without a fixed card group is cancelled, for the subsequent lamination with the pressure roller assembly, the possibility of contact between the pressure roller assembly and the fixed card group is reduced, thereby reducing the collision of the composite layer and ensuring the quality of the composite layer after lamination.

[0022] 2. Compared with the prior art, the present invention is provided with improvements on the negative pressure transport component, and adopts an electric roller structure with a built-in motor. This electric roller structure makes the overall volume smaller and is only provided with a mounting rod at the outer end. Based on this mounting rod, the negative pressure transport component is provided with a corresponding transverse moving groove, and then, according to the specific size of the composite layer, a suitable number of electric roller structures with built-in motors can be arranged in the transverse moving groove, and there is space and position to arrange the negative pressure device, so that the negative pressure device can act on the composite layer, and a certain suction force is generated for the composite layer, thereby achieving the fixation of the composite layer, which is beneficial for the subsequent pressure roller component to act on the composite layer and perform lamination processing on the composite layer.

[0023] 3. Compared with the existing technology, the present device is provided with a pressure roller assembly. The most important feature of the pressure roller assembly is that it can expand. Through the expandable pressure roller assembly, the distances between adjacent pressure roller assemblies and the base surface are different. For this distance, it is a step change. This step change can effectively reduce the impact of hard contact caused by the lamination of traditional pressure roller assemblies and composite layers, thereby improving the phenomenon of composite layer splitting caused by hard contact in the roller forming process of traditional care face cloths.

[0024] 4. Compared with the prior art, the present invention is specially provided with an arc frame and an electric rotating roller arranged based on the arc direction of the arc frame for the purpose of colliding the pressure roller assembly. Compared with the traditional horizontal frame, the traditional horizontal frame has no curvature, so it is very difficult to design an expandable pressure roller assembly. The expandable pressure roller assembly is required to have a large expansion distance, which makes the design difficult. Therefore, the present device directly sets up an arc frame, uses the arc frame to realize arc installation, and then installs the expandable pressure roller assembly. For the expandable pressure roller assembly, it is only necessary to realize fine-position expansion.

[0025] 5. Compared with the existing technology, the electric rotating roller set based on the arc direction of the arc frame can achieve gradual lamination by itself. However, for some lamination processes, fine lamination is required. Therefore, an expandable pressing roller assembly is set to achieve fine adjustment of the upper and lower distances of the expandable pressing roller assembly, so that the lamination is more precise and the quality of the laminated composite layer is higher, meeting the corresponding production process.

Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings can be obtained based on these drawings without creative work.

[0028] Figure 2 A schematic side view of a pad surface fabric processing device proposed in an embodiment of the present application is shown;

[0029] Figure 3 A schematic diagram of the expansion of a pressure roller assembly of a pad cover cloth processing device proposed in an embodiment of the present application is shown. DETAILED DESCRIPTION

[0030] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] The figure marks in the drawings of the specification include: base 1, stabilizing column 2, pin hole 3, arc frame 4, pin 5, electric rotating roller 6, support frame 7, annular mounting groove 8, lateral movement area 9, electric roller structure 10, locking nut 11, negative pressure part 12, composite layer 13, extension rod 14, inflatable airbag 15, expansion plate 16.

[0032] Implementation example Figure 1-Figure 3 As shown:

[0033] A device for processing a protective pad surface cloth comprises a base 1, an arc-shaped frame 4 detachably connected to the base 1, an electric rotating roller 6 arranged based on the arc-shaped direction of the arc-shaped frame 4, an expandable pressure roller assembly arranged on the periphery of the electric rotating roller 6, and a negative pressure transport assembly arranged on the base 1 and arranged along the length of the base 1 for transporting a composite layer 13, wherein the spacing between adjacent pressure roller assemblies and the surface of the base 1 is different.

[0034] About the base 1: the base 1 adopts a concave base 1, the negative pressure transport component is installed in the concave position of the concave base 1, and a stabilizing column 2 is provided at the bottom of the concave base 1. The free end of the stabilizing column 2 is fixed with a rubber anti-slip pad in contact with the ground.

[0035] About negative pressure transport components:

[0036] like Figure 1 As shown, the negative pressure transport component includes a transport part and a negative pressure part 12, the transport part has symmetrically arranged annular mounting grooves 8, a support frame 7 for supporting the annular mounting grooves 8, a plurality of lateral movement areas 9 arranged in the annular mounting grooves 8, an electric roller structure 10 installed in the lateral movement area 9 and having a built-in motor, and a locking member for fixing the electric roller structure 10, and the negative pressure part 12 is arranged between adjacent support frames 7.

[0037] The number of electric roller structures 10 with built-in motors that can match the composite layer 13 is set through the lateral movement area 9. The electric roller structure 10 has a built-in motor, which makes the overall volume of the electric roller structure 10 smaller and more beautiful. The locking member is a locking nut 11. Because both ends of the electric roller structure 10 with a built-in motor are mounting rods, the overall installation can be completed by directly fixing the mounting rods through the locking nut 11. It will not affect the rotation of the electric roller structure 10 with a built-in motor, because the moving surface of the electric roller structure 10 with a built-in motor is on the end surface, and the rotor is driven by gears inside. For example, a micro electric roller with a diameter of 50 has this structure.

[0038] Since the negative pressure layer is directly placed on the rotating surface of the electric roller structure 10 for transportation, there is no fixed card group in this case to avoid the collision of the composite layer 13. Therefore, a negative pressure part 12 is set. The negative pressure part 12 includes a plurality of suction holes opened on the base 1, a conduit for connecting the suction holes and an external negative pressure machine. After the negative pressure machine is connected to the conduit, the suction holes generate negative pressure.

[0039] The composite layer 13 is sucked onto the rotating surface of the motorized roller structure 10 by negative pressure, thereby achieving the fixing effect of the negative pressure layer;

[0040] like Figure 1 and Figure 2 As shown:

[0041] The base 1 is provided with a latch hole 3, and latches 5 are provided at both ends of the bottom of the arc frame 4. The latch 5 is connected to the latch hole 3 by a snap connection. Since the arc frame 4 has a certain curvature, in order to ensure that the latch 5 is connected to the latch hole 3, the bottom of the latch 5 can be threadedly connected with an extension rod 14, so that the latch 5 is better connected to the latch hole 3, and the arc direction of the arc frame 4 gradually becomes smaller along the movement direction of the negative pressure transport component, so as to achieve gradual lamination and reduce hard contact.

[0042] like Figure 3 As shown:

[0043] The pressure roller assembly includes an inner frame fixed to the rotating outer ring of the electric rotating roller 6, partition plates evenly fixed around the inner frame, several installation areas formed based on the partition plates, an inflatable airbag 15 arranged in the installation area, and an expansion plate 16 arranged at the expansion end of the inflatable airbag 15, and the expansion plate 16 is arranged corresponding to the installation area.

[0044] In terms of specific structure:

[0045] The electric rotating roller 6 has the same structure as the electric roller structure 10 with a built-in motor, both of which adopt a built-in motor layout. The pressure roller assembly is fixedly connected to the electric rotating roller 6. Specifically: the fixed end of the inflatable airbag 15 is installed inside the installation area, and the expansion end of the inflatable airbag 15 is fixed to the expansion plate 16. When the inflatable airbag 15 is not inflated, the expansion plate 16 is combined into a circle. After the inflatable airbag 15 is inflated, the expansion plate 16 expands outward along the expansion direction of the inflatable airbag 15.

[0046] The reason for setting up the arc frame 4 is that compared with the traditional horizontal frame, the traditional horizontal frame has no curvature, so it is very difficult to design an expandable pressure roller assembly. The expandable pressure roller assembly is required to have the characteristic of a large expansion distance, and the design difficulty is relatively high. Therefore, the present device directly sets up the arc frame 4, and uses the arc frame 4 to realize the arc installation, and then the expandable pressure roller assembly is used. For the expandable pressure roller assembly, only fine expansion needs to be realized. Regarding fine expansion: the electric rotating roller 6 set based on the arc direction of the arc frame 4 can realize gradual lamination by itself, but for some lamination processes, fine lamination is required. Therefore, an expandable pressure roller assembly is set to realize fine adjustment of the upper and lower distances of the expandable pressure roller assembly, so that the lamination is more precise, and the laminated composite layer 13 is of higher quality, meeting the corresponding production process.

[0047] Secondly, since this case adopts the expansion of the inflatable airbag 15, when the inflatable airbag 15 expands, the expansion plate 16 expands outward along the expansion direction of the inflatable airbag 15, and there is a gap between adjacent expansion plates 16. If a large expansion is adopted, the gap is too large, which is not good for the lamination effect, because the composite layer 13 is not in contact with the expansion plate 16, resulting in a decrease in the lamination effect. Therefore, a small expansion is adopted, and the small gap generated has little effect on the lamination of the composite layer 13. In order to achieve a small expansion, an arc frame 4 is adopted.

[0048] The purpose of the present invention is to improve the phenomenon that the composite layer 13 is split due to hard contact during the roll-forming process of the conventional care face cloth.

[0049] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
