Description

Technical Field

[0001] This invention belongs to the field of scouring pad winding technology, specifically referring to a winding device for scouring pad production and its usage method. Background Technology

[0002] Scouring pads, as a flexible and elastic sheet material, are approximately 10mm thick in their natural state, but can be compressed to one-third to one-quarter of their original thickness. This type of low-density material takes up a lot of space and has low transportation efficiency during transport and storage, resulting in relatively high costs. Since semi-finished scouring pads are typically stored in rolls, compressing their volume during storage could significantly reduce transportation and storage costs. Summary of the Invention

[0003] Thanks to the inherent properties of scouring pads, even prolonged compression will not affect their elasticity and other properties after release. In order to overcome the shortcomings of the prior art, this invention proposes a storage method of degassing and then rolling up the pads. This method not only avoids creases and wrinkles caused by vacuum compression, but also avoids material rebound caused by the rupture of the plastic film during transportation and storage.

[0004] This solution proposes a rolling assembly, a negative pressure holding assembly, and a pressure stabilizing assembly. Through mechanical extrusion and negative pressure holding, it can achieve the technical effect of compressing the thickness of the material and maintaining its compressed state. Furthermore, in order to monitor whether there is abnormal rebound of the outermost coiled material, this invention also proposes an extrusion partition assembly and a loosening monitoring assembly. Through the synchronous feedback of the extrusion roller and the partition roller, a signal can be issued when there is abnormal rebound of the coiled material between them.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a winding device for the production of scouring pads, including a rolling assembly, a negative pressure holding assembly, an extrusion partition assembly, a loosening monitoring assembly, a pressure stabilizing assembly, a longitudinal displacement assembly, a winding assembly, a square tube frame, and a rolled material. The rolling assembly is located on the top of the square tube frame, the negative pressure holding assembly is located on the extrusion partition assembly, the extrusion partition assembly is located on the rolling assembly, and the loosening monitoring assembly is located between the rolling assembly and the extrusion partition assembly.

[0006] The pressure stabilizing component and the longitudinal displacement component are symmetrically arranged on both sides of the square tube frame. The winding component is rotatably arranged in the pressure stabilizing component. The rolled material is wound on the winding component. The end of the rolled material is slidably arranged in the negative pressure holding component. The rolled material is covered with a plastic film.

[0007] Furthermore, the rolling assembly includes a T-shaped support, an extrusion roller, and an extrusion cylinder. The T-shaped support is located on the top of the square tube frame, the extrusion roller is rotatably mounted in the T-shaped support, and the extrusion cylinder is fixedly connected to the extrusion roller.

[0008] The extrusion rollers can compress rolled materials, transforming them from a soft to a compressed state. Roller extrusion can significantly reduce the vacuum requirement in the negative pressure box. By reducing the working pressure, the specifications of the components can be significantly reduced, thereby lowering costs and improving the safety and stability of the equipment during operation.

[0009] Furthermore, the negative pressure holding assembly includes a base plate, a negative pressure box, and a negative pressure connector. The base plate is disposed on the extrusion partition assembly, and a rounded corner guide portion is provided on one side of the base plate. The negative pressure box is disposed above the base plate, and the rolled material is slidably disposed between the base plate and the negative pressure box. The negative pressure box is provided with an arc-shaped portion, and a notch is provided at the arc-shaped portion.

[0010] The negative pressure in the negative pressure box works in conjunction with the extrusion rollers to achieve the technical effect of compressing the thickness of the material and maintaining its compressed state.

[0011] Preferably, the negative pressure box is provided with a negative pressure pipe array above it, and the negative pressure connector is provided on the negative pressure pipe.

[0012] Furthermore, the extrusion partition assembly includes a partition roller, a partition drum, and a portal frame. The portal frame is mounted on a T-shaped support, the base plate is positioned above the portal frame, the partition roller is rotatably mounted in the T-shaped support, and the partition drum is mounted on the partition roller.

[0013] The partition roller can press against the surface of the rolled material and maintain compression; the partition roller can both compress the thickness of the material and prevent it from rebounding, and can also provide feedback on the moving speed of the rolled material at that position through the rolling contact between the two.

[0014] Furthermore, the loosening monitoring component includes a compression gear, a partition gear, a thin toothed belt, and a tensile detection patch. The compression gear is fixed to the compression roller, the partition gear is fixed to the partition roller, the thin toothed belt meshes with the compression gear, and the thin toothed belt meshes with the partition gear. The tensile detection patch is attached to the outside of the thin toothed belt and has built-in electronic components that can issue an alarm when the thin toothed belt is stretched too much.

[0015] Since both the extrusion roller and the partition roller are in rolling contact with the compressed roll material, if the roll material is kept compressed, the extrusion roller and the partition roller should rotate at the same speed. The tension detection patch located on the thin toothed belt can provide feedback on the synchronization of the extrusion gear and the partition gear, thereby determining whether the compressed roll material has rebounded (when the roll material rebounds, not only will the thickness change, but the length will also increase).

[0016] Furthermore, the pressure stabilizing component includes a constant pressure cylinder and a longitudinal slider. The air inlet of the external air pump is connected to a negative pressure connector, and the air outlet of the external air pump is connected to the constant pressure cylinder. The air inlet of the constant pressure cylinder has a vent window.

[0017] Preferably, the constant pressure cylinder is mounted on a square tube frame, the longitudinal slider is mounted on the telescopic rod of the constant pressure cylinder, the longitudinal slider has a central hole, and the two ends of the longitudinal slider have symmetrical side holes.

[0018] Under the premise of stable air pump pressure, the thrust provided by the constant pressure cylinder remains constant regardless of the extension length, thereby ensuring that the extrusion pressure between the rolled material and the partition roller is neither too large nor too small.

[0019] Furthermore, the longitudinal displacement assembly includes a longitudinal guide rail and a linear bearing. The longitudinal guide rail is fixed to the square tube frame, and the linear bearing is fixed to the side hole. The linear bearing is engaged and slidably disposed on the longitudinal guide rail.

[0020] Furthermore, the winding assembly includes a winding spindle, a winding bearing, and a winding roller. The winding bearing is disposed in a central hole, the partition roller is disposed in the winding bearing, the winding roller is disposed on the winding spindle, the rolled material is wound on the winding roller, and a power input section is provided at the end of the winding spindle.

[0021] This invention also proposes a method for using a winding device for the production of scouring pads, specifically including the following steps:

[0022] Step 1: Before entering the negative pressure box, a plastic film is placed over the roll of material, closed at the front and open at the top; the sealing device with the top opening is located between the extrusion roller and the negative pressure connector. After passing through the sealing device, the film completely wraps around the roll of material, so the roll of material in the negative pressure box is still in contact with the outside world, while the roll of material after passing through the extrusion roller is isolated from the outside world; the output shaft of the external motor is connected to the power input unit.

[0023] The ends of the rolled material are fixed to the winding drum after being squeezed by the extrusion roller, and the rolled material is then wound up by the rotation of the winding drum.

[0024] Step 2: The external air pump works, drawing gas from the negative pressure box and supplying gas into the constant pressure cylinder, creating a negative pressure state inside the negative pressure box.

[0025] Step 3: The constant pressure cylinder is under positive pressure, but due to the presence of the vent, the constant pressure cylinder will not continue to extend. Instead, it will maintain a certain upward thrust after the wound material comes into contact with the partition roller.

[0026] Step 4: If the extrusion roller and the partition roller rotate at the same speed during the continuous rotation of the winding roller, it means that there is no obvious rebound of the rolled material between the extrusion roller and the partition roller. If the outermost rolled material does not rebound, the inner rolled material will also not rebound.

[0027] Step 5: If the length of the rolled material between the extrusion roller and the partition roller increases due to springback, the rotation speed of the partition roller will be greater than that of the extrusion roller. At this time, the asynchrony between the extrusion gear and the partition gear will cause the thin toothed belt to be locally stretched and drive the stretch detection patch to be stretched. The stretch detection patch has metal contacts inside. After being stretched and separated, it will generate a signal change, which will be fed back to the outside.

[0028] Step Six: As winding continues, the longitudinal slider will gradually descend along the longitudinal guide rail. After winding is complete, the roll of material can be tied up from the outer ring with straps. After tying, even if the plastic film breaks during transportation, the entire roll of material will not return to its original position.

[0029] The beneficial effects achieved by the present invention using the above structure are as follows:

[0030] (1) The extrusion roller can extrude the rolled material, so that it changes from its original soft form to a compressed form; the roller extrusion can significantly reduce the vacuum requirement in the negative pressure box. By reducing the working pressure, the component specifications can be significantly reduced, the cost can be reduced, and the safety and stability of the equipment during operation can be improved.

[0031] (2) The negative pressure in the negative pressure box works in conjunction with the extrusion roller to achieve the technical effect of compressing the thickness of the material and maintaining its compressed state.

[0032] (3) The partition roller can press against the surface of the rolled material and keep it compressed; the partition roller can compress the thickness of the material and prevent it from rebounding, and can also provide feedback on the moving speed of the rolled material at that position through the rolling contact between the two.

[0033] (4) Since both the extrusion roller and the partition roller are in rolling contact with the compressed roll material, if the roll material is kept compressed, the extrusion roller and the partition roller should rotate at the same speed. The tension detection patch located on the thin toothed belt can provide feedback on the synchronization of the extrusion gear and the partition gear, thereby determining whether the compressed roll material has rebounded (when the roll material rebounds, not only will the thickness change, but the length will also increase).

[0034] (5) Under the premise of stable air pump pressure, the thrust provided by the constant pressure cylinder remains unchanged regardless of the extension length, so as to keep the extrusion pressure between the rolled material and the partition roller neither too large nor too small.

[0047] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0048] like Figures 1-9 As shown, the present invention proposes a winding device and its usage method for the production of scouring pads, including a rolling assembly 1, a negative pressure holding assembly 2, a compression isolation assembly 3, a loosening monitoring assembly 4, a pressure stabilizing assembly 5, a longitudinal displacement assembly 6, a winding assembly 7, a square tube frame 8, and a rolled material 9. The rolling assembly 1 is located on the top of the square tube frame 8, the negative pressure holding assembly 2 is located on the compression isolation assembly 3, the compression isolation assembly 3 is located on the rolling assembly 1, and the loosening monitoring assembly 4 is located between the rolling assembly 1 and the compression isolation assembly 3.

[0049] The pressure stabilizing component 5 and the longitudinal displacement component 6 are symmetrically arranged on both sides of the square tube frame 8. The winding component 7 is rotatably arranged in the pressure stabilizing component 5. The rolled material 9 is wound on the winding component 7. The end of the rolled material 9 is slidably arranged in the negative pressure holding component 2. The rolled material 9 is covered with a plastic film 91.

[0050] The rolling assembly 1 includes a T-shaped support 11, an extrusion roller 12, and an extrusion drum 13. The T-shaped support 11 is located on the top of the square tube frame 8, the extrusion roller 12 is rotatably located in the T-shaped support 11, and the extrusion drum 13 is fixedly connected to the extrusion roller 12.

[0051] The extrusion roller 13 can compress the rolled material 9, changing it from its original soft state to a compressed state. Roller extrusion can significantly reduce the vacuum requirement in the negative pressure box 22. By reducing the working pressure, the requirements for component specifications can be significantly reduced, costs can be reduced, and the safety and stability of the equipment during operation can be improved.

[0052] The negative pressure holding assembly 2 includes a base plate 21, a negative pressure box 22, and a negative pressure connector 23. The base plate 21 is disposed on the extrusion partition assembly 3. A rounded corner guide portion 211 is provided on one side of the base plate 21. The negative pressure box 22 is disposed above the base plate 21. The rolled material 9 is slidably disposed between the base plate 21 and the negative pressure box 22. An arc-shaped portion 221 is provided on the negative pressure box 22, and a notch 222 is provided at the arc-shaped portion 221.

[0053] The negative pressure in the negative pressure box 22 works in conjunction with the extrusion roller 13 to achieve the technical effect of compressing the thickness of the material and maintaining its compressed state.

[0054] The negative pressure box 22 is provided with negative pressure pipes 223 arranged above it, and negative pressure connectors 23 are provided on the negative pressure pipes 223.

[0055] The extrusion partition assembly 3 includes a partition roller 31, a partition drum 32, and a portal frame 33. The portal frame 33 is mounted on a T-shaped support 11, and the base plate 21 is mounted above the portal frame 33. The partition roller 31 is rotatably mounted in the T-shaped support 11, and the partition drum 32 is mounted on the partition roller 31.

[0056] The partition roller 32 can press against the surface of the rolled material 9 and maintain compression; the partition roller 32 can both compress the thickness of the material and prevent it from rebounding, and can also provide feedback on the moving speed of the rolled material 9 at that position through the rolling contact between the two.

[0057] The loosening monitoring component 4 includes a compression gear 41, a partition gear 42, a thin toothed belt 43, and a tensile detection patch 44. The compression gear 41 is fixed to the compression roller 12, the partition gear 42 is fixed to the partition roller 31, the thin toothed belt 43 meshes with the compression gear 41 for transmission, and the thin toothed belt 43 meshes with the partition gear 42 for transmission. The tensile detection patch 44 is attached to the outside of the thin toothed belt 43. The tensile detection patch 44 has built-in electronic components that can issue an alarm when the tensile range of the thin toothed belt 43 is too large.

[0058] Since both the extrusion roller 13 and the partition roller 32 are in rolling contact with the compressed roll material 9, if the roll material 9 remains compressed, the extrusion roller 13 and the partition roller 32 should rotate at the same speed. The tension detection patch 44 located on the thin toothed belt 43 can provide feedback on the synchronization degree of the extrusion gear 41 and the partition gear 42, thereby determining whether the compressed roll material 9 has rebounded (when the roll material 9 rebounds, not only will its thickness change, but its length will also increase).

[0059] The pressure stabilizing component 5 includes a constant pressure cylinder 51 and a longitudinal slider 52. The air inlet of the external air pump is connected to the negative pressure connector 23, and the air outlet of the external air pump is connected to the constant pressure cylinder 51. The air inlet of the constant pressure cylinder 51 has a vent window.

[0060] The constant pressure cylinder 51 is mounted on the square tube frame 8, and the longitudinal slider 52 is mounted on the telescopic rod of the constant pressure cylinder 51. The longitudinal slider 52 has a central hole 521 and side holes 522 symmetrically arranged at both ends.

[0061] Under the premise of stable air pump pressure, the thrust provided by constant pressure cylinder 51 remains constant regardless of the extension length, thereby keeping the extrusion pressure between the rolled material 9 and the partition roller 32 neither too large nor too small.

[0062] The longitudinal displacement assembly 6 includes a longitudinal guide rail 61 and a linear bearing 62. The longitudinal guide rail 61 is fixed to the square tube frame 8, and the linear bearing 62 is fixed to the side hole 522. The linear bearing 62 is engaged and slidably disposed on the longitudinal guide rail 61.

[0063] The winding assembly 7 includes a winding spindle 71, a winding bearing 72, and a winding roller 73. The winding bearing 72 is disposed in the center hole 521, the partition roller 31 is disposed in the winding bearing 72, the winding roller 73 is disposed on the winding spindle 71, and the rolled material 9 is wound on the winding roller 73. The end of the winding spindle 71 is provided with a power input part 711.

[0064] In practical use, before entering the negative pressure box 22, the plastic film 91 is placed on the outside of the roll material 9, with the front end closed and the top open; the sealing device with the top opening is located between the extrusion roller 12 and the negative pressure connector 23. After passing through the sealing device, the film completely wraps around the roll material 9, so the roll material 9 in the negative pressure box 22 is still in contact with the outside world, while the roll material 9 after passing through the extrusion roller 13 is isolated from the outside world; the output shaft of the external motor is connected to the power input unit 711.

[0065] The end of the rolled material 9 is fixed to the winding roller 73 after being squeezed by the extrusion roller 13, and the rolled material 9 is subsequently wound up by the rotation of the winding roller 73.

[0066] An external air pump operates, drawing gas from the negative pressure box 22 and supplying gas into the constant pressure cylinder 51. The negative pressure box 22 is in a negative pressure state. The negative pressure in the negative pressure box 22 cooperates with the extrusion roller 13 to achieve the technical effect of compressing the thickness of the material and maintaining its compressed state.

[0067] The constant pressure cylinder 51 is under positive pressure, but due to the presence of the vent window, the constant pressure cylinder 51 will not continue to extend. Instead, it will maintain a certain upward thrust after the wound material 9 abuts against the partition roller 32.

[0068] If the extrusion roller 13 and the partition roller 32 rotate at the same speed during the continuous rotation of the winding roller 73, it means that there is no obvious rebound of the rolled material 9 between the extrusion roller 13 and the partition roller 32. If the outermost rolled material 9 does not rebound, the inner rolled material 9 will also not rebound.

[0069] If the length of the rolled material 9 between the extrusion roller 13 and the partition roller 32 increases due to springback, the rotational speed of the partition roller 32 will be greater than that of the extrusion roller 13. At this time, the asynchrony between the extrusion gear 41 and the partition gear 42 will cause the thin toothed belt 43 to be locally stretched and drive the stretch detection patch 44 to be elongated. The stretch detection patch 44 has metal contacts inside, which will generate signal changes after being stretched and separated, and thus feed back to the external terminal.

[0070] As winding continues, the longitudinal slider 52 will gradually descend along the longitudinal guide rail 61. After winding is completed, the roll of material 9 can be tied from the outer ring with straps. After tying, even if the plastic film is broken during transportation, the entire roll of material 9 will not return to its original position.

[0071] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0072] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.

Step 5: If the length of the rolled material (9) between the extrusion roller (13) and the partition roller (32) increases due to springback, the rotation speed of the partition roller (32) will be greater than that of the extrusion roller (13). At this time, the asynchrony between the extrusion gear (41) and the partition gear (42) will cause the thin toothed belt (43) to be stretched locally and drive the stretch detection patch (44) to be stretched. The stretch detection patch (44) has metal contacts inside. After being stretched and separated, it will generate a signal change, which will be fed back to the outside. Step 6: As winding continues, the longitudinal slider (52) will gradually descend along the longitudinal guide rail (61). After winding is completed, the rolled material (9) can be tied from the outer ring with a strap.
