Description

Technical Field

[0001] The present application relates to the technical field of diaphragm production, and in particular to a cutting device for core-wrap edge material and a core-wrap system. Background Art

[0002] During the diaphragm production process, a winding core is required to wind the diaphragm. Since the produced winding core has internal stress, it is necessary to use a winding core with a cotton-wrapped sheet bonded to the surface to wind the diaphragm, and then eliminate the stress in the winding core by letting it stand still.

[0003] After the cotton-covered sheet is bonded to the surface of the core, the excess edges of the cotton-covered sheet need to be cut along the axial direction of the core. Currently, the cutting method is mostly manual cutting, which is prone to uneven edges after cutting, or too large a gap between the edges of the cotton-covered sheet on the axis of the core after cutting, resulting in scrapping. Utility Model Content

[0004] The purpose of the present application is to provide a cutting device for core-wrap edge material and a core-wrap system, so that the edges of the core-wrap sheet bonded to the core can be cut more smoothly.

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

[0006] In a first aspect, an embodiment of the present application provides a device for cutting the cotton-wrapped edge material of a core, comprising a frame, a fixing assembly and a cutting assembly. The fixing assembly comprises a first support plate and a second support plate arranged opposite to each other along a first direction, the first support plate and the second support plate are respectively used to support the two ends of the core to which the cotton-wrapped sheet is bonded, and the first support plate and the second support plate are both slidably arranged on the frame so that the core moves to a cutting position along a second direction. The cutting assembly comprises a first slide rail arranged along a first direction and a tool assembly slidably arranged on the first slide rail, and the cutting assembly is configured such that when the tool assembly slides along the first slide rail, the cotton-wrapped sheet of the core located at the cutting position is cut along the first direction.

[0007] In the cutting device provided by the above technical solution, the core to be processed is supported by the fixing component and sent to the cutting position, and the cutting component cuts the cotton-wrapped core bonded to the surface of the core. The tool component in the cutting component cuts the cotton-wrapped sheet bonded to the core at the cutting position along the first direction. The cutting device provided by the above technical solution is used to cut the cotton-wrapped sheet bonded to the surface of the core, and the edge of the cotton-wrapped sheet after cutting is relatively straight, and the edge after cutting is smoother than that of manual cutting.

[0008] In some optional embodiments, the frame is provided with a second slide rail extending along the second direction, and the fixing assembly also includes a slide plate, the lower side of which is slidably connected to the second slide rail; one end of the upper side of the slide plate is connected to the first support plate, and the other end is connected to the second support plate.

[0009] In the above technical solution, the first support plate and the second support plate are arranged on the slide plate, and the slide plate is slidably connected to the second slide rail arranged on the frame, so that the fixed component can slide relative to the frame.

[0010] In some optional embodiments, both the first support plate and the second support plate have a positioning surface for supporting the winding core, and the positioning surface is an arc-shaped surface or a V-shaped surface.

[0011] In the above technical solution, by setting positioning surfaces on the first support plate and the second support plate to carry the winding core, the winding core can have a relatively fixed position on the first support plate and the second support plate, so as to facilitate more accurate cutting of the cotton-wrapped sheet adhered to the surface of the winding core.

[0012] In some optional embodiments, the first support plate and the second support plate each have a limiting surface facing the positioning surface in the first direction, and the limiting surface is used to limit the displacement of the winding core supported on the first support plate and the second support plate in the first direction.

[0013] In the above technical solution, the displacement of the winding core in the first direction can be limited by the limiting surface, so as to effectively avoid the situation where the cotton-covered sheet is not completely cut when the tool assembly moves to the extreme position along the first direction due to unreasonable placement of the winding core.

[0014] In some optional embodiments, the frame is further provided with a laser generator for irradiating the edge of the cotton-wrapped sheet bonded to the core, and the laser generator is used to emit light parallel to the first direction.

[0015] When using the cutting device provided by the above technical solution, the winding core can be positioned circumferentially by aligning the edge of the cotton-wrapped sheet with the light to ensure that the blade is always in the overlapping part of the sheet, thereby ensuring the cutting gap.

[0016] In some optional embodiments, the frame is also connected to two vertically arranged third slide rails, and the two ends of the first slide rail are respectively slidably arranged on the two third slide rails. The first slide rail is configured to move along the third slide rail in a direction away from or close to the cutting position to lift and lower the cutting assembly.

[0017] In the above technical solution, the third slide rail is provided so that the first slide rail can be raised and lowered, which can facilitate moving the winding core provided with the cotton-wrapped sheet material to the cutting position through the fixing assembly.

[0018] In some optional embodiments, the first slide rail is connected to a first cylinder and the fixed assembly is connected to a second cylinder; the first cylinder is configured to move the first slide rail along the third slide rail, and the second cylinder is configured to move the fixed assembly along the second slide rail.

[0019] In the above technical solution, the first slide rail and the fixed component are driven to move by the cylinder, which is easy to control.

[0020] In some optional embodiments, the first direction is perpendicular to the second direction, the cutting assembly includes a first blade and a second blade, and the first blade and the second blade are spaced apart along the first direction and the second direction.

[0021] In the above technical solution, by arranging the first blade and the second blade spaced apart in the first direction and the second direction, it can be achieved that when cutting the cotton-bagged sheet, the first blade and the second blade move synchronously and cut the cotton-bagged sheet successively, which can improve the cutting accuracy and the flatness of the edge of the cotton-bagged sheet after cutting.

[0022] In some optional embodiments, the cutting assembly also includes a first pressure block and a second pressure block fixed to the first slide rail, the first pressure block and the second pressure block are spaced apart along the second direction, and the first blade and the second blade are both arranged between the first pressure block and the second pressure block; the first pressure block and the second pressure block are configured to contact the cotton-wrapped sheet on the outer peripheral surface of the roll core arranged at the cutting position during the downward movement of the first slide rail.

[0023] In the above technical solution, the first pressing block and the second pressing block are arranged to contact the cotton-wrapped sheet, and the first blade and the second blade pass between the first pressing block and the second pressing block, which can reduce the displacement of the cotton-wrapped sheet during the cutting process, thereby ensuring the cutting accuracy.

[0024] In the second aspect, an embodiment of the present application provides a core wrapping system, comprising a core wrapping device and a cutting device provided in the first aspect, wherein the core wrapping device is used to bond a cotton wrapping sheet to the outer peripheral surface of the core, and the cutting device is used to cut the edge of the cotton wrapping sheet on the outer peripheral surface of the core provided by the core wrapping device.

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

[0038] The present application provides a core wrapping system including a core wrapping device and a cutting device 100. The core wrapping device is used to bond a wrapping sheet 300 to the outer peripheral surface of a core 200, thereby obtaining Figure 1 The winding core 200 is shown with a cotton-wrapped sheet 300 bonded to the surface. The winding core 200 is an annular structure, and the surface to which the cotton-wrapped sheet 300 is bonded is the outer peripheral surface of the winding core 200. Figure 1 Since the size of the cotton-wrapped sheet 300 is larger than that of the winding core 200, Figure 1 The middle cotton sheet 300 is cut along the axial direction of the winding core 200 .

[0039] In the present application, a cutting device 100 is used to cut the cotton-wrapped sheet 300 along the axial direction of the winding core 200. Figure 2 and Figure 3As shown, the cutting device 100 includes a frame 110, a fixing assembly 120 and a cutting assembly 130. The fixing assembly 120 is installed on the frame 110, and is used to carry the winding core 200 with the cotton-wrapped sheet 300 bonded on the surface, and to send the winding core 200 to the cutting position. When the winding core 200 is in the cutting position, it can be cut by the cutting assembly 130.

[0040] In some embodiments of the present application, the cutting assembly 130 includes a first direction (ie, Figure 3 The first slide rail 131 is provided (in the direction indicated by the arrow A) and the knife assembly 132 is slidably provided on the first slide rail 131. When the blade moves along the first slide rail 131, the cotton-wrapped sheet 300 can be cut on the winding core 200 in the cutting position.

[0041] In some embodiments, the fixing assembly 120 includes a first support plate 121 and a second support plate 122 arranged opposite to each other along a first direction, and the first support plate 121 and the second support plate 122 are respectively used to support the two ends of the core 200. It is not difficult to understand that when the core 200 is supported by the first support plate 121 and the second support plate 122, the axis of the core 200 is parallel to the first direction. By supporting the ends of the core 200 by the first support plate 121 and the second support plate 122, the fixing assembly 120 can be prevented from contacting the cotton-wrapped sheet 300 as much as possible. The first support plate 121 and the second support plate 122 are both slidably arranged on the frame 110, so that the core 200 can be sent to the cutting position after being supported by the first fixing assembly 120, thereby reducing the possibility of interference between the core 200 and the cutting device 100 during the process of installing the core 200, and making the operation more convenient.

[0042] The first support plate 121 and the second support plate 122 both have a positioning surface 124 for supporting the winding core 200. The positioning surface 124 may be an arcuate surface or a V-shaped surface. By supporting the end of the winding core 200 on the positioning surface 124, the winding core 200 can be positioned. It is not difficult to understand that the positioning surface 124 is located on the upper side of the first support plate 121 and the second support plate 122.

[0043] Furthermore, the first support plate 121 and the second support plate 122 also have a limiting surface 125, which is used to limit the position of the winding core 200 supported by the first support plate 121 and the second support plate 122 in the first direction, thereby preventing the winding core 200 from moving along the first direction during the process of cutting the cotton-wrapped sheet 300 along the first direction. Figure 3As shown, the limiting surfaces 125 in the first support plate 121 and the second support plate 122 are both set toward the first direction, that is, the limiting surfaces 125 are surfaces in the first support plate 121 and the second support plate 122 that are perpendicular to the first direction, and the limiting surfaces 125 are at least partially higher than the positioning surface 124 so as to contact the end surface of the winding core 200 supported on the positioning surface 124.

[0044] In some embodiments, the fixing assembly 120 further includes a slide plate 123, and the frame 110 is provided with a slide plate 123 along the second direction (ie Figure 3 The first support plate 121 and the second support plate 122 are respectively arranged at two ends of the slide plate 123. It is not difficult for those skilled in the art to understand that when implementing this solution, the first support plate 121 and the second support plate 122 are both arranged on the same side of the slide plate 123. Figure 3 In the embodiment shown, the lower side of the slide plate 123 is slidably connected to the second slide rail 111, one end of the upper side of the slide plate 123 is connected to the first support plate 121, and the other end of the upper side is connected to the second support plate 122, so that the first support plate 121 and the second support plate 122 are both slidably arranged on the frame 110. Further, the number of the second slide rails 111 is two, and the two second slide rails 111 are respectively arranged below the two ends of the slide plate 123, such as Figure 3 As shown, a second slide rail 111 is located below the first support plate 121, and another second slide rail 111 is located below the second support plate 122. By arranging the second slide rails 111 at both ends of the slide plate 123, the weight of the core 200 is better transferred to the second slide rails 111, thereby reducing the deformation of the slide plate 123 and further reducing the impact on the cutting accuracy.

[0045] In some embodiments of the present application, the first direction and the second direction are perpendicular to each other. Figure 3 In the illustrated embodiment, the extension direction of the first rail 131 is perpendicular to the extension direction of the second rail 111. In other embodiments, the first direction and the second direction may be two directions with an acute angle, or even parallel to each other.

[0046] In some embodiments, in order to facilitate the circumferential positioning of the core 200 on the fixing assembly 120, the frame 110 is further connected to a laser generator 112 for irradiating the edge of the cotton-wrapped sheet 300 bonded to the core 200, and the laser generator 112 is used to emit light parallel to the first direction. In the process of using the cutting device 100 provided in this embodiment, the core 200 can be positioned circumferentially by aligning the edge of the cotton-wrapped sheet 300 with the light to control the amount of the edge of the cotton-wrapped sheet 300 to be cut, thereby avoiding the situation where the gap between the two side edges of the cotton-wrapped sheet 300 extending along the axis of the core 200 after cutting is too large.

[0047] The laser generator 112 may be directly connected to the frame 110 or indirectly connected to the frame 110. In the embodiment where the laser generator 112 is indirectly connected to the frame 110, the laser generator 112 may be disposed on the fixing assembly 120, such as the slide plate 123 or the first support plate 121 or the second support plate 122 disposed in the fixing assembly 120; or the laser generator 112 may be disposed on the cutting assembly 130, such as the first slide rail 131 or the cutter assembly 132. As long as it can be achieved that the edge of the cotton-bagged sheet 300 can be aligned with the light emitted by the laser generator 112 before cutting the cotton-bagged sheet 300.

[0048] In some embodiments, the first slide rail 131 is also slidably disposed relative to the frame 110 to make the cutting device 100 more flexible. For example, by slidably disposing the first slide rail 131, the distance between the cutter assembly 132 and the core 200 in the cutting position can be changed to accommodate distances of different sizes; and the interference between the core 200 and the cutting assembly 130 can also be reduced when the core 200 is sent to the cutting position.

[0049] Further, in some embodiments, the first slide rail 131 slides relative to the frame 110 in the vertical direction, and the first slide rail 131 is located above the cutting position. When using the cutting device 100 provided in this embodiment, before the core 200 is sent to the cutting position through the fixing assembly 120, the first slide rail 131 is located at a higher position. After the core 200 is sent to the cutting position, the first slide rail 131 drives the cutting assembly 130 to move downward, and then the cotton-wrapped sheet 300 on the surface of the core 200 is cut. In other embodiments, the first slide rail 131 can also slide relative to the frame 110 in the second direction, that is, the first slide rail 131 moves toward the cutting position in the horizontal direction.

[0050] In an embodiment in which the first slide rail 131 slides in a vertical direction relative to the frame 110, two third slide rails 113 can also be vertically arranged on the frame 110, and the two ends of the first slide rail 131 are respectively slidably arranged on the two third slide rails 113, and the extension direction of the third slide rail 113 is a vertical direction. Therefore, the first slide rail 131 can slide in a vertical direction relative to the frame 110, and then the cutting assembly 130 can be lifted and lowered.

[0051] In order to cut the cotton-covered sheet 300 in an automated manner, in some embodiments, the first slide rail 131 is connected to the first cylinder 115, and the fixing assembly 120 is connected to the second cylinder 116. The first slide rail 131 is driven to move in the direction of the cutting position by the first cylinder 115; the fixing assembly 120 is driven by the second cylinder 116 to drive the winding core 200 to move to the cutting position. Further, a column 114 for mounting the first cylinder 115 can also be provided on the frame 110, and the distance between the column 114 and the two third slide rails 113 in the first direction is equal, that is, the first cylinder 115 is connected to the middle of the first slide rail 131, so that the force of the first slide rail 131 is more balanced, and it is not easy to get stuck with the third slide rail 113 at one end. Further, the second cylinder 116 is also provided with the frame 110 and connected to the slide plate 123 to drive the slide plate 123 to move. Similarly, the second cylinder 116 is also connected to the middle position of the slide plate 123.

[0052] In some embodiments of the present application, the cutting assembly 130 includes a tool assembly 132, and the tool assembly 132 includes a first blade 1321 and a second blade 1322. The first blade 1321 and the second blade 1322 are spaced apart in the first direction and the second direction. That is, in the first direction, the first blade 1321 and the second blade 1322 are spaced apart; in the second direction, the first blade 1321 and the second blade 1322 are spaced apart. By cutting with the first blade 1321 and the second blade 1322 at the same time, the cutting accuracy and the flatness of the edge of the cotton-wrapped sheet 300 after cutting can be improved. Further, as Figure 4 and Figure 5 As shown, the cutter assembly 132 further includes a cutter seat 1323, the first blade 1321 and the second blade 1322 are both fixed to the cutter seat 1323, the cutter seat 1323 is slidably connected to the first slide rail 131, and a handle is also provided on the cutter seat 1323. The operator drives the cutter seat 1323 to move along the first slide rail 131 through the handle, thereby moving the cutter assembly 132 along the first direction, so as to cut the cotton-wrapped sheet 300 bonded to the surface of the winding core 200 at the cutting position.

[0053] Further, in some embodiments, the cutting assembly 130 further includes a first pressing block and a second pressing block, both of which extend in the first direction and are arranged at intervals in the second direction. It is not difficult to understand that the gap between the first pressing block and the second pressing block also extends in the first direction. The first blade 1321 and the second blade 1322 are arranged in the gap. The first pressing block and the second pressing block are relatively fixedly connected to the first slide rail 131, that is, during the lifting and lowering of the first slide rail 131, the first pressing block and the second pressing block are lifted and lowered together, and during the downward movement of the first pressing block and the second pressing block, they can contact the cotton-wrapped sheet 300 on the outer peripheral surface of the winding core 200 arranged at the cutting position. During the cutting process using the cutting device 100 provided in this embodiment, the first blade 1321 and the second blade 1322 pass between the first pressing block and the second pressing block, which can reduce the displacement of the cotton-wrapped sheet 300 during the cutting process, thereby ensuring the cutting accuracy.

[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.
