[0002] In the diaphragm production technology, it is necessary to use a winding core provided with a cotton-wrapped sheet to wind the diaphragm. Currently, the cotton-wrapping process is mostly completed by manually pasting the cotton-wrapped sheet on the outer circumference of the winding core. The cotton-wrapped sheet is a rectangular sheet-shaped structural member. After the cotton-wrapping process is completed, the excess edges of the sheet need to be cut.

[0003] The manual cotton wrapping process may result in uneven wrapping edges, that is, the edge of the cotton wrapping sheet is not parallel to the axis of the winding core. Utility Model Content

[0004] The purpose of the present application is to provide a device for wrapping cotton on a core to improve the situation of uneven wrapping edges.

[0005] The embodiment of the present application is implemented as follows:

[0006] An embodiment of the present application provides a device for wrapping cotton on a core, comprising a workbench and a cotton wrapping assembly.

[0007] The cotton packing assembly includes a fixing assembly and a limiting assembly. The fixing assembly is used to support the opposite ends of the winding core and to set the winding core on the feeding side. The limiting assembly is configured to align the winding core with the cotton packing sheet on the working surface so as to push the winding core through the cotton packing sheet set on the working surface.

[0008] In the above technical solution, since the position of the winding core is adjusted by the limiting assembly, the winding core can be aligned with the cotton-wrapped sheet on the working surface. When the winding core is pushed toward the cotton-wrapped sheet, the cotton-wrapped sheet can be adhered to the preset position on the outer peripheral surface of the winding core. Therefore, the uneven edge situation can be improved.

[0009] In some optional embodiments, the working surface also has a blocking side arranged opposite to the feeding side along the first direction, and the area between the feeding side and the blocking side of the working surface is used to place the cotton-wrapped sheet, and the blocking side is provided with a blocking piece for limiting the cotton-wrapped sheet from leaving the working surface from the feeding side to the blocking side.

[0011] In the above technical scheme, the first surface of the material blocking member is used to limit the movement of the cotton-wrapped sheet in the first direction to prevent the cotton-wrapped sheet from detaching from the working surface from the feeding side to the blocking side; the second surface of the material blocking member is used to limit the movement of the cotton-wrapped sheet in the second direction to enable the cotton-wrapped sheet to be bonded to a preset position on the outer peripheral surface of the winding core, further improving the uneven edge wrapping situation.

[0012] In some optional embodiments, the workbench is also provided with two core limiting members, each of which has a core limiting surface; the core limiting surfaces of the two core limiting members are arranged relatively to each other along the second direction on the workbench, and the two second surfaces are both located between the two core limiting surfaces, and the two core limiting surfaces are used to limit the displacement of the core pushed to the work surface in the direction of its own axis.

[0013] In the above technical solution, during the cotton wrapping process, the winding core rolls on the cotton wrapping sheet along the first direction, and the two winding core limiting surfaces are used to limit the displacement of the winding core pushed to the working surface in the direction of its own axis, so that the cotton wrapping sheet can be adhered to the preset position on the outer peripheral surface of the winding core, further improving the uneven edge wrapping situation.

[0014] In some optional embodiments, limiting assemblies are provided on both sides of the fixed assembly, each limiting assembly includes a push plate and a first driving member, a winding core is provided between the two push plates, and the first driving member drives the connected push plates to drive the push plates to move in the second direction so that the winding core is aligned with the cotton-wrapped sheet on the working surface.

[0015] In the above technical solution, the limiting component can adjust the position of the core carried on the fixed component in the second direction so that the two ends of the core are aligned with the core limiting parts, so that when the core is pushed along the first direction to contact the cotton-wrapped sheet, the core can be smoothly pushed between the two core limiting surfaces.

[0016] In some optional embodiments, the fixing assembly includes two supporting plates arranged opposite to each other, one supporting plate is used to support one end of the winding core, and the other supporting plate is used to support the other end of the winding core.

[0017] The fixing components provided in the above-mentioned embodiment are used to support both ends of the winding core. On the one hand, it is convenient to apply force to the winding core to push the winding core toward the feeding side. On the other hand, the contact area between the winding core and the support plate is small, which can reduce the damage of the support plate to the surface of the winding core.

[0018] In some optional embodiments, the support plate has a positioning surface for supporting the winding core, and the positioning surface is an arc-shaped surface or a V-shaped surface.

[0019] In some optional embodiments, the fixed component is connected to a lifting component, and the lifting component is used to drive the fixed component to move up and down so that the height of the winding core corresponds to the height of the working surface.

[0020] In the above technical solution, by setting a lifting component to drive the fixed component to move up and down, the height of the winding core can be adjusted so that the height of the winding core corresponds to the height of the working surface, which facilitates pushing the winding core to the feeding side.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] The present application provides a device for wrapping cotton on a core to assist in the process of pasting a cotton wrapping sheet 900 on the outer peripheral surface of a core 800, that is, to obtain Figure 1 The process of winding core 800 is shown.

[0037] The device for wrapping core provided in the present application comprises a workbench 100 and a wrapping assembly 200 for placing a core 800. Figure 2 As shown, the workbench 100 has a work surface 110 for placing the cotton packing sheet 900. By pushing the winding core 800 placed on the cotton packing assembly 200 toward the workbench 100, the winding core 800 rolls over the surface of the cotton packing sheet 900 and is bonded to the cotton packing sheet 900.

[0038] It is not difficult to understand that since the winding core 800 is bonded to the cotton-bundled sheet 900 when rolling through the cotton-bundled sheet 900, when using the device provided in the present application, it is necessary to set an adhesive on one side of the cotton-bundled sheet 900, and the cotton-bundled sheet 900 is placed on the working surface 110 with the side provided with the adhesive facing upward.

[0039] Further, the working surface 110 has a feeding side 111; the cotton packing assembly 200 includes a fixing assembly 210 and a limiting assembly 220. The fixing assembly 210 is used to carry the winding core 800, and the fixing assembly 210 is arranged on the feeding side 111 of the working surface 110, so that the winding core 800 is pushed toward the cotton packing sheet 900 arranged on the working surface 110 through the feeding side 111 of the working surface 110. The limiting assembly 220 is used to adjust the position of the winding core 800 so that the winding core 800 is aligned with the cotton packing sheet 900 arranged on the working surface 110, so that when the winding core 800 is pushed toward the cotton packing sheet 900, the cotton packing sheet 900 is attached to a preset position on the outer peripheral surface of the winding core 800.

[0040] When the cotton wrapping process is carried out using the device provided in the present application, since the position of the winding core 800 is adjusted by the limiting assembly 220, the winding core 800 can be aligned with the cotton wrapping sheet 900 on the working surface 110. When the winding core 800 is pushed toward the cotton wrapping sheet 900, the cotton wrapping sheet 900 can be adhered to a preset position on the outer peripheral surface of the winding core 800. Therefore, the uneven wrapping edge problem can be improved.

[0041] In the embodiments provided in the present application, the workbench 100 and the cotton packing assembly 200 may be connected or independent of each other. For example, in some embodiments, the cotton packing assembly 200 may be installed on the working surface 110 of the workbench 100; in other embodiments, the cotton packing assembly 200 and the workbench 100 are structures directly connected to the ground.

[0042] In some embodiments of the present application, Figure 2As shown, the working surface 110 also has a stopper side 112 opposite to the feeding side 111, and the area of ​​the working surface 110 between the feeding side 111 and the stopper side 112 is used to place the cotton-covered sheet 900. Further, the stopper side 112 is provided with a stopper 300, and the stopper 300 is used to limit the cotton-covered sheet 900 from the feeding side 111 to the stopper side 112 from leaving the working surface 110. It is not difficult to understand that in the process of cotton-covering, in the process of pushing the winding core 800 from the feeding side 111 to the working surface 110, since the winding core 800 rolls over the surface of the cotton-covered sheet 900, the cotton-covered sheet 900 has the risk of leaving the working surface 110 from the stopper side 112. By providing the stopper 300 on the stopper side 112, the movement of the cotton-covered sheet 900 in this direction can be limited. In this embodiment, the material blocking member 300 can be fixedly connected to the workbench 100; or other connection methods can be used, so that the feeding side 111 and the material blocking side 112 are connected along the first direction (ie Figure 2 The direction indicated by the arrow A in the middle is taken as an example, as long as the first blocking member 300 cannot move along the first direction.

[0043] Further, in some embodiments of the present application, Figure 3 As shown, the material stopper 300 is L-shaped, and has a first surface 310 and a second surface 320 perpendicular to each other. The material stopper side 112 of the working surface 110 is provided with two material stoppers 300, and the first surfaces 310 of the two material stoppers 300 are both arranged toward the feeding side 111, so as to achieve the effect of limiting the cotton-wrapped sheet 900 from escaping from the feeding side 111 to the material stopper side 112 when the winding core 800 rolls through the cotton-wrapped sheet 900. The second surfaces 320 of the two material stoppers 300 are arranged along the second direction (i.e. Figure 2 The stopper 300 is arranged relative to the first surface 310 and the second surface 320, and the stopper 300 limits the cotton-covered sheet 900 arranged on the working surface 110 between the two second surfaces 320. In other embodiments, the stopper 300 may also be in other shapes, as long as it has a first surface 310 that can be arranged parallel to the second direction to limit the cotton-covered sheet 900 from the feeding side 111 to the stopper side 112 to separate from the working surface 110, and also has a second surface 320 that can be arranged parallel to the first direction to limit the cotton-covered sheet 900 between the two stoppers 300.

[0044] It is not difficult to understand that the second direction is perpendicular to the first direction, and the first surface 310 and the second surface 320 are perpendicular to each other and the first surface 310 is arranged toward the feeding side 111; during the cotton wrapping process, the rolling direction of the winding core 800 is parallel to the first direction; the first surface 310 of the material stopper 300 is used to limit the movement of the cotton wrapping sheet 900 in the first direction to prevent the cotton wrapping sheet 900 from detaching from the working surface 110 from the feeding side 111 to the material stopper side 112; the second surface 320 of the material stopper 300 is used to limit the movement of the cotton wrapping sheet 900 in the second direction, so that the cotton wrapping sheet 900 can be bonded to the preset position of the outer peripheral surface of the winding core 800. Further, the thickness of the material stopper 300 should not be greater than the thickness of the cotton wrapping sheet 900, so that the outer peripheral surface of the winding core 800 can contact the cotton wrapping sheet 900 during the rolling process.

[0045] Further, in some embodiments, Figure 2 As shown, two core limiters 400 are also provided on the workbench 100, and the core limiters 400 have core limiter surfaces 410. The core limiter surfaces 410 of the two core limiters 400 are arranged opposite to each other along the second direction on the workbench 100, and the two second surfaces 320 are both located between the two core limiter surfaces 410. During the cotton wrapping process, the core 800 rolls on the cotton wrapping sheet 900 along the first direction, and the two core limiter surfaces 410 are used to limit the displacement of the core 800 pushed to the work surface 110 in its own axial direction (that is, in the second direction), so that the cotton wrapping sheet 900 can be bonded to the preset position of the outer peripheral surface of the core 800. After the cotton wrapping process is completed, there are partial areas at both ends of the core 800 where the cotton wrapping sheet 900 is not provided. It should not be difficult for those skilled in the art to understand that the winding core limiting surface 410 has a certain size in the first direction, and the size is close to the size of the cotton-wrapped sheet 900 in the first direction after being placed on the working surface 110 .

[0046] In some embodiments of the present application, Figure 2 and Figure 4 As shown, limiting components 220 are also provided on both sides of the fixing component 210, that is, along the second direction, one limiting component 220 is located at one end of the fixing component 210, and the other limiting component 220 is located at the other end of the fixing component 210. The limiting component 220 can adjust the position of the winding core 800 carried on the fixing component 210 in the second direction, so that both ends of the winding core 800 are aligned with the winding core limiting member 400, and further, in the process of pushing the winding core 800 to contact the cotton-wrapped sheet 900 along the first direction, the winding core 800 can be smoothly pushed between the two winding core limiting surfaces 410.

[0047] exist Figure 4 and Figure 5In the illustrated embodiment, the limiting assembly 220 includes a push plate 222 and a first driving member 221, the driving member is used to drive the push plate 222 to move, the push plates 222 are both arranged toward the fixed assembly 210, and a space for placing the winding core 800 is formed between the two push plates 222. The push plate 222 moves along the second direction under the drive of the first driving member 221 to push the winding core 800 from the end of the winding core 800, thereby adjusting the position of the winding core 800 in the second direction, so that the winding core 800 carried on the fixed assembly 210 is aligned with the cotton-wrapped sheet 900 on the working surface 110, so that when the winding core 800 is pushed toward the cotton-wrapped sheet 900, the cotton-wrapped sheet 900 is attached to a preset position on the outer peripheral surface of the winding core 800. Figure 4 In the illustrated embodiment, the first driving member 221 is a cylinder. In other embodiments, the first driving member 221 may also be a transmission mechanism such as a hydraulic cylinder, a ball screw, or a screw nut structure in the prior art.

[0048] In some embodiments of the present application, the fixing assembly 210 for carrying the core 800 includes two supporting plates 211 arranged opposite to each other, that is, the fixing assembly 210 is used to support both ends of the core 800, one supporting plate 211 supports one end of the core 800, and the other supporting plate 211 supports the other end of the core 800. When the core 800 is carried on the fixing assembly 210, the portion of the core 800 located between the two supporting plates 211 is in a suspended state. It is not difficult to understand that the two supporting plates 211 are arranged opposite to each other in the second direction, so that when the core 800 is carried on the fixing assembly 210, its axis is parallel to the second direction, so as to realize the process of applying a force along the first direction toward the feeding side 111 to the core 800, thereby rolling the core 800 through the cotton-wrapped sheet 900 arranged on the working surface 110, and bonding the cotton-wrapped sheet 900 to the outer peripheral surface of the core 800.

[0049] The fixing assembly 210 provided in the above embodiment is used to support both ends of the core 800. On the one hand, it is convenient to apply force to the core 800 to push the core 800 toward the feed side 111. On the other hand, the contact area between the core 800 and the support plate 211 is small, which can reduce the damage of the support plate 211 to the surface of the core 800.

[0050] Further, if Figure 4 As shown, the support plate 211 has a positioning surface 212 for supporting the winding core 800, and the positioning surface 212 is an arc-shaped surface or a V-shaped surface, so that the winding core 800 is in a specific position after being supported on the positioning surface 212. For the size of the positioning surface 212 and the distance from the working surface 110 in the vertical direction, those skilled in the art can set it according to the standard that the winding core 800 does not have a large height fluctuation during the process of being pushed to contact the cotton-covered sheet 900.

[0051] Furthermore, in order to adjust the position of the winding core 800 in the vertical direction to change the distance between the winding core 800 carried by the fixing assembly 210 and the working surface 110, the fixing member is further connected to a lifting assembly 500. The lifting assembly 500 is used to drive the fixing assembly 210 to move up and down so that the height of the winding core 800 carried by the fixing assembly 210 corresponds to the height of the working surface 110, so as to facilitate pushing the winding core 800 to the feeding side 111.

[0052] In some embodiments, the lifting assembly 500 includes a lifting plate 510 and a second driving member 520 connected to each other, and two support plates 211 are spaced apart at both ends of the lifting plate 510 along the second direction. The second driving member 520 is used to drive the lifting plate 510 to move up and down, thereby realizing the up and down movement of the fixing assembly 210. In one embodiment, the second driving member 520 can be a cylinder in the prior art, and in other embodiments, the second driving member 520 can also be a transmission mechanism such as a hydraulic cylinder, a ball screw or a screw nut structure in the prior art.

[0053] In some embodiments, in order to facilitate adjustment of the distance between the winding core 800 carried by the fixing assembly 210 and the feeding side 111, the fixing assembly 210 is installed on the workbench 100, and a guide rail 610 whose extension direction is consistent with the first direction is also provided on the workbench 100, and a slide plate 620 is slidably connected above the guide rail 610. The fixing assembly 210 is provided on the slide plate 620, and by moving the slide plate 620 along the guide rail 610, the fixing assembly 210 can be moved in a direction close to or away from the feeding side 111. Further, the number of the guide rails 610 is at least one. In one embodiment, the number of the guide rails 610 is two, and the two guide rails 610 are arranged in parallel, and one end of the slide plate 620 is slidably connected to one guide rail 610, and the other end is slidably connected to the other guide rail 610. The fixing assembly 210 can be directly arranged on the slide 620, such as the support plate 211 in the fixing assembly 210 is directly connected to the upper side of the slide 620; the fixing assembly 210 can also be indirectly arranged on the slide 620, such as, when the fixing assembly 210 is arranged on the slide 620 and is also connected to the lifting assembly 500, it is not difficult to understand that the lifting assembly 500 can be connected to the slide 620 at one end and connected to the fixing assembly 210 at the other end, so that the fixing assembly 210 and the slide 620 are indirectly connected, so as to change the distance between the fixing assembly 210 and the slide 620, and then change the distance between the fixing assembly 210 and the working surface 110. Further, in Figure 4 In the illustrated embodiment, the limiting assembly 220 is also disposed on the slide plate 620 .

[0054] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
