Abstract
Description
Technical Field
[0001] This application relates to the technical field of diaphragm preparation devices, and more particularly, to a core wrapping cotton device. Background Art
[0002] During the diaphragm preparation process, it is usually necessary to wind the diaphragm using a paper tube core.
[0003] However, during the winding process of the lithium battery diaphragm, deformation will occur due to reasons such as diaphragm stress release or thermal expansion and contraction. When the diaphragm deforms, problems such as wrinkles or edge collapse will occur on the film surface. To improve the problem of film surface deformation, a layer of buffer cotton is usually pasted on the paper tube core. When the diaphragm deforms, the buffer cotton will deform preferentially to relieve the diaphragm deformation.
[0004] Currently, the method of pasting buffer cotton is mainly to manually push the paper tube core to roll on the buffer cotton to attach the buffer surface to the surface of the paper tube core. However, manually rolling the core to paste cotton will cause a certain degree of waste of human resources and time. Therefore, it is necessary to provide an automatic cotton pasting device to improve production efficiency and reduce labor costs at the same time. Utility Model Content
[0005] Based on the above deficiencies, this application provides a core wrapping cotton device to improve the production efficiency and quality of core wrapping cotton, and reduce labor costs at the same time.
[0006] This application is implemented as follows:
[0007] An example of this application provides a core wrapping cotton device, including a frame, a cotton wrapping mechanism, and a support mechanism. The cotton wrapping mechanism includes a workbench arranged on the frame, and the workbench is used to place cotton wrapping sheets; the workbench has a feeding side, and the workbench is inclined downward towards the feeding side; the support mechanism includes a first moving component and two rotatable air chucks, the first moving component is arranged on the frame, the two rotatable air chucks are arranged on the first moving component, the first moving component moves the two air chucks closer to each other so that the two air chucks clamp the core along both axial ends; the first moving component can also selectively drive the two air chucks to move towards the feeding side so that the core clamped between the two air chucks can abut against the cotton wrapping sheet on the feeding side, and the two air chucks rotate so that the cotton wrapping sheet is wound and wrapped around the circumferential surface of the core.
[0008] When using the above-mentioned core wrapping cotton device to wrap cotton on the surface of the core, the two ends of the core can be aligned with the two air chucks. The distance between the two air chucks is adjusted by the first moving component, so that the two air chucks clamp the core between them. Then, the first moving component can be used again to move the core clamped between the two air chucks to the feeding side of the workbench. The workbench is inclined towards the feeding side, and the cotton wrapping sheet is placed on the workbench. When the core moves to the feeding side, it can abut against the cotton wrapping sheet above the feeding side of the workbench, pressing tightly against the end of the cotton wrapping sheet, so that the end of the cotton wrapping sheet adheres to the core. Then, the rotation of the air chuck can drive the rotation of the core, so that the cotton wrapping sheet gradually wraps around the circumferential surface of the core. During the cotton wrapping process, the core is always fixed to the air chuck. As the air chuck rotates, the cotton wrapping sheet placed on the inclined workbench is subjected to a tensile force and gradually slides down along the workbench. When each part of the cotton wrapping sheet slides between the core and the feeding side of the workbench, it will be adhered to the surface of the core due to the extrusion force between the core and the feeding side of the workbench. During the cotton wrapping process, there is no need to push the core to roll upward along the cotton wrapping sheet on the workbench, and the air chuck will not affect the quality of the cotton wrapping sheet wrapped on the surface of the core, which can improve the cotton wrapping quality.
[0009] In an alternative embodiment, the core wrapping cotton device further includes:
[0010] A cutting mechanism, including a second moving component and a tool provided on the frame; the second moving component can selectively drive the tool to move up and down and move axially along the core; the first moving component can selectively move back and forth between the cotton wrapping mechanism and the cutting mechanism; when the first moving component drives the two air chucks to move to the cotton wrapping mechanism, the core clamped between the two air chucks can abut against the cotton wrapping sheet on the feeding side; when the first moving component drives the two air chucks to move to the cutting mechanism, the core clamped between the two air chucks is located below the tool, and the second moving component can selectively drive the tool to descend to abut against the cutting position of the cotton wrapping sheet, and the second moving component drives the tool to move axially to cut the cotton wrapping sheet at the cutting position.
[0011] In the above implementation process, when the first moving component drives the two air chucks to move to the cotton wrapping mechanism, the core clamped between the two air chucks can abut against the cotton wrapping sheet at the feeding side of the workbench. Through the rotation of the air chucks, the cotton wrapping sheet is gradually wrapped around the surface of the core. Generally, there is a margin in the size of the cotton wrapping sheet compared to the circumference of the core, and there will be excess cotton wrapping sheet at the start and end positions of the core corresponding to the wrapping of the cotton wrapping sheet, and the excess cotton wrapping sheet needs to be cut. Using the core cotton wrapping device provided by the examples of the present application, after the cotton wrapping sheet is wrapped around the circumferential surface of the core, the first moving component can be used to move the core wrapped with the cotton wrapping sheet to the cutting mechanism. Since the cutting mechanism is provided with a second moving component and a tool, the second moving component can drive the tool to descend and abut against the cutting position of the cotton wrapping sheet, and then the second moving component drives the tool to move along the axial direction of the core, so that the tool can cut the cotton wrapping sheet at the cutting position along the axial direction.
[0012] In an alternative embodiment, the first moving component includes a first linear moving member, a first mounting plate, and a second linear moving member; the two air chucks are respectively arranged at both ends of the first mounting plate, the first linear moving member is arranged on the first mounting plate, and the first linear moving member can selectively drive one of the air chucks to move, so that the core is clamped between the two air chucks; the first mounting plate is arranged on the second linear moving member, and the second linear moving member drives the first mounting plate to move back and forth between the cotton wrapping mechanism and the cutting mechanism.
[0013] In the above implementation process, when cotton wrapping needs to be performed on the core, the first linear moving member can be used to drive the air chuck to move, so as to fix the core between the two air chucks and enable the core to rotate with the rotation of the air chuck. After fixation, the second linear moving member can be used to drive the first mounting plate, the first linear moving member arranged on the first mounting plate, the air chuck, and the core clamped between the two air chucks to move to the cutting mechanism, so that the core abuts against the cotton wrapping sheet on the feeding side of the workbench, and then the cotton wrapping is gradually fixed on the surface of the core with the rotation of the core. After the cotton wrapping is completed, the second linear moving member can be used again to drive the first mounting plate, the first linear moving member arranged on the first mounting plate, the air chuck, and the core clamped between the two air chucks to move to the cutting mechanism, so that the cutting mechanism can cut the cutting position of the cotton wrapping sheet.
[0014] In an alternative embodiment, the support mechanism further includes a first driving member, and the first driving member is connected to one of the air chucks; when the core clamped between the two air chucks abuts against the cotton wrapping sheet on the feeding side, the first driving member drives the air chuck to rotate, so that the cotton wrapping sheet is wound and wrapped around the circumferential surface of the core.
[0015] In the above implementation process, a first driving member is used to drive one of the air chuck to rotate, and the air chuck can drive the core and the other air chuck to rotate, thereby gradually covering the cotton wrapping sheet on the surface of the core.
[0016] In an alternative embodiment, the support mechanism is further provided with a first sensor; the first sensor is disposed at one end of the second linear moving member close to the feeding side; when the second linear moving member drives the first mounting plate to move to the cotton wrapping mechanism, the first sensor sends a signal to the first driving member, and the first driving member drives the air chuck to rotate.
[0017] In the above implementation process, since a first sensor is disposed at one end of the second linear moving member close to the cotton wrapping mechanism, the first sensor can sense whether the first mounting plate moves to the cotton wrapping mechanism. When the first sensor senses that the first mounting plate moves to the cotton wrapping mechanism, the first sensor can send a signal to the first driving member to automatically drive the air chuck to rotate for automatic cotton wrapping.
[0018] In an alternative embodiment, the first linear moving member includes a slide rail disposed on the first mounting plate and a slider slidably connected to the slide rail; one of the air chucks is fixed to the slider through a first mounting seat; the first linear moving member further includes a cylinder locking member, the fixed end of the cylinder locking member is fixedly connected to the slider, and the output end of the cylinder locking member can optionally abut against the first mounting plate to limit the slider from sliding along the slide rail.
[0019] In the above implementation process, the air chuck is slidably connected to the slider through the slider, and the distance between the two air chucks can be adjusted by pushing the slider to slide along the slide rail. After the slider is slid to the target position, the locking cylinder can be opened to make the output end of the locking cylinder abut against the mounting plate, and the abutting action between the locking cylinder and the mounting plate is used to limit the movement of the slider along the slide rail.
[0020] In an alternative embodiment, the second moving assembly includes two lifting members and a third linear moving member; the two lifting members are axially spaced apart, and the first moving assembly is located between the two lifting members; the two lifting members are respectively connected to the third linear moving member for driving the third linear moving member to perform a lifting movement; the third linear moving member is connected to the tool for driving the tool to slide axially.
[0021] In the above implementation process, the two lifting members are located outside the first moving assembly, so that the first moving assembly can drive the core to move between the two lifting members and below the third linear moving member. When the lifting member drives the third linear moving member to descend so that the tool abuts against the cutting position, the third linear moving member can drive the tool to slide axially along the core to cut the cutting position.
[0022] In an alternative embodiment, the support mechanism further includes a second sensor disposed on the lifting member. When the first moving assembly drives the two air chucks to move to the cutting mechanism, the second sensor sends a signal to the lifting member, and the lifting member moves downward to make the cutting tool abut against the cutting position of the cotton wrapping sheet material.
[0023] In the above implementation process, a second sensor is provided at the lifting member. The second sensor can sense whether the first mounting plate has moved to the position of the lifting member. When the second sensor senses that the first mounting plate has moved to the position of the lifting member, the second sensor can send a signal to the lifting member, and the lifting member can automatically lower the cutting tool to abut tightly against the cutting position, so that the third moving member drives the cutting tool to slide along the cutting position to cut the cutting position.
[0024] In an alternative embodiment, the third linear moving member has opposite first and second ends. The third linear moving member is used to drive the cutting tool to slide from the first end to the second end. The cutting mechanism further includes a third sensor disposed at the second end. When the third linear moving member drives the cutting tool to slide from the first end to the second end, the third sensor sends a signal to the lifting member, and the lifting member moves upward to move the cutting tool away from the core.
[0025] In the above implementation process, a third sensor is provided at the second end of the third linear moving member. When the third sensor senses the cutting tool, it means that the cutting tool has moved from the first end to the second end to complete the cutting of the cutting position. Then the third sensor sends a signal to the lifting member to make the lifting member drive the cutting tool to rise away from the core.
[0026] In an alternative embodiment, the cutting mechanism further includes a second mounting plate. The third linear moving member is connected to the two lifting members through the second mounting plate. The second mounting plate has a strip-shaped hollow portion extending along the axial direction. The cutting tool passes through the hollow portion and extends below the second mounting plate. The cutting mechanism further includes two pressing blocks disposed on both sides of the hollow portion at the bottom of the second mounting plate, so that the cutting tool is located between the two pressing blocks. When the lifting member moves downward to make the cutting tool abut against the cutting position of the cotton wrapping sheet material, the two pressing blocks are pressed tightly against both sides of the cutting position.
[0027] In the above implementation process, a strip-shaped hollow portion extending along the axial direction is provided in the middle of the second mounting plate, which can enable the bottom end of the cutting tool to pass through the hollow portion and abut against the cutting position. Pressing blocks are provided on both sides of the second mounting plate corresponding to the hollow portion. When the lifting member drives the cutting tool to abut against the cutting position, the pressing blocks on both sides of the cutting tool can press both sides of the cutting position, which can improve the cutting quality when the cutting tool performs cutting.

[0043] During the process of diaphragm preparation, it is usually necessary to use the paper tube core 101 for winding the diaphragm. In order to improve the problem of film surface deformation, a layer of buffer cotton is usually pasted on the paper tube core 101. When the diaphragm deforms, the buffer cotton will deform preferentially to relieve the diaphragm deformation.
[0044] Currently, the method of pasting buffer cotton is mainly to manually roll the paper tube core 101 on the cotton wrapping sheet 102 to attach the buffer surface to the surface of the paper tube core 101. However, manually rolling the core 101 to paste cotton will cause a certain degree of waste of human resources and time.
[0045] Therefore, this application provides a core cotton wrapping device 1 that can automatically wrap cotton on the core 101. To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application.
[0046] Please refer to Figure 1 , the core wrapping cotton device 1 provided by the example of the present application includes a frame 10, a cotton wrapping mechanism 20 and a support mechanism 30.
[0047] Please combine with Figure 1 and Figure 2 , the cotton wrapping mechanism 20 includes a workbench 21 arranged on the frame 10, and the workbench 21 is used for placing the cotton wrapping sheet 102. The workbench 21 has a feeding side 211, and the workbench 21 is arranged to slope downwards towards the feeding side 211.
[0048] Please combine with Figure 1 and Figure 3 , the support mechanism 30 includes a first moving component 31 and two rotatable air chucks 32 arranged on the first moving component 31. The first moving component 31 is arranged on the frame 10 to make the two air chucks 32 approach each other, so that the two air chucks 32 clamp the core 101 at both ends along the axial direction D1. The first moving component 31 can also optionally drive the two air chucks 32 to move towards the feeding side 211, so that the core 101 clamped between the two air chucks 32 can abut against the cotton wrapping sheet 102 on the feeding side 211, and the two air chucks 32 rotate to wind and wrap the cotton wrapping sheet 102 around the circumferential surface of the core 101.
[0049] The following further describes in detail the frame 10, the cotton wrapping mechanism 20 and the support mechanism 30 in the core wrapping cotton device 1 provided by the example of the present application with reference to the accompanying drawings.
[0050] The frame 10 is used to carry the cotton wrapping mechanism 20 and the support mechanism 30. In some possible embodiments, in order to facilitate the setting of the cotton wrapping mechanism 20 and the support mechanism 30, a machine table can be set at the frame 10, and the cotton wrapping mechanism 20 and the support mechanism 30 are arranged on the machine table.
[0051] Further, in order to facilitate the first moving component in the support mechanism 30 to drive the core 101 to move to the cotton wrapping sheet 102 at the feeding side 211 of the cotton wrapping mechanism 20, in some possible embodiments, the first moving component 31 can be arranged on the machine table, and a first installation position is set at the machine table. The feeding side 211 of the workbench 21 of the cotton wrapping mechanism 20 is arranged above the first installation position, so that when the first moving component 31 drives the core 101 to move to the first installation position, the core arranged on the first moving component 31 can abut against the cotton wrapping sheet 102 above the feeding side 211. The position where the feeding side of the cotton wrapping mechanism 20 is located directly opposite to the machine table is the first installation position.
[0052] Further, in order to facilitate the installation of the winding core 101, in a possible embodiment, a third installation position may be provided on the frame 10. The first installation position and the third installation position are two installation positions spaced a certain distance apart on the mounting platform. The first moving assembly 31 moves back and forth between the first installation position and the third installation position.
[0053] When the first moving component 31 drives the air expansion chuck 32 to move to the third installation position, the operator can take and place the winding core 101. When the winding core 101 fixed at the air expansion chuck 32 needs to be moved to the cotton wrapping mechanism 20 for cotton wrapping, the first moving component 31 can be moved to the first installation position, so that the winding core 101 is against the cotton wrapping sheet 102 on the feeding side 211, and the air expansion chuck 32 drives the winding core 101 to rotate, so that the cotton wrapping sheet 102 is covered on the surface of the winding core 101.
[0054] The cotton wrapping mechanism 20 includes a workbench 21 disposed on the frame 10, and the workbench 21 is tilted downward toward the feeding side 211. The cotton wrapping sheet 102 placed on the workbench 21 can slide downward along the tilted workbench 21 under the action of the pulling force generated by the rotation of the winding core 101.
[0055] Exemplarily, a mounting frame can be set on the side of the first mounting position of the frame 10 away from the third mounting position, and the side of the mounting frame facing the first mounting position is lower than the side of the mounting frame away from the first mounting position. The workbench 21 is set on the mounting frame so that the workbench 21 is tilted downward toward the feeding side 211.
[0056] Furthermore, in order to reduce the lateral displacement of the cotton-wrapped sheet 102 when it slides downward along the workbench 21 and wraps around the winding core 101, in some possible embodiments, limit plates 22 can be set at both ends of the workbench 21 along the axial direction D1, and the cotton-wrapped sheet 102 is placed between the two limit plates 22, and the two sides of the cotton-wrapped sheet 102 along the axial direction D1 slide along the limit plates 22.
[0057] Furthermore, in order to meet the requirements of cotton wrapping of winding cores 101 of different lengths, in a possible embodiment, two limiting plates 22 are movably disposed on the workbench 21 along the axial direction D1.
[0058] For example, a mounting hole extending along the axial direction D1 may be provided at the top of the workbench 21, and a matching piece capable of matching with the mounting hole and being fixed at one position of the mounting hole along the axial direction D1 is provided at the top of the limiting plate 22. For example, the mounting hole may be a bar-shaped threaded hole, and the matching piece may be a stud.
[0059] The supporting mechanism 30 is used to carry the core 101, make the core 101 abut against the cotton wrapping sheet 102 on the feeding side 211, and drive the core 101 to rotate by using the air chuck 32, and gradually wrap the cotton wrapping sheet 102 around the core 101.
[0060] In some possible embodiments, please refer to Figure 1 and Figure 3 , the first moving component 31 includes a first linear moving member 311, a first mounting plate 312 and a second linear moving member 313.
[0061] Two air chucks 32 are arranged at both ends of the first mounting plate 312, and the first linear moving member 311 can drive one of the first mounting plates 312 to move.
[0062] Exemplarily, please refer to Figure 3 , the first mounting plate 312 extends along the axial direction D1, an air chuck 32 is arranged at one end of the first mounting plate 312, and the first linear moving member 311 is arranged at the other end of the first mounting plate 312. Another air chuck 32 is arranged on the first linear moving member 311, and the first linear moving member 311 can drive the air chuck 32 to move along the axial direction D1.
[0063] Exemplarily, please continue to refer to Figure 3 , the first linear moving member 311 includes a slide rail 3111 and a slider 3112, and the slide rail 3111 extends along the axial direction D1. The slider 3112 is slidably connected to the slide rail 3111, and the air chuck 32 is arranged on the slider 3112 through a mounting seat.
[0064] After moving the slider 3112 along the slide rail 3111 to the target position, in order to facilitate fixing the slider 3112 at the target position of the slide rail 3111, in one possible embodiment, please continue to refer to Figure 3 , a cylinder locking member 3113 is arranged at the slider 3112, and the output end of the cylinder locking member 3113 can optionally abut against the first mounting plate 312. When the output end of the cylinder locking member 3113 abuts against the first mounting plate 312, under the abutting action of the cylinder locking member 3113 and the first mounting plate, the slider 3112 cannot continue to slide along the slide rail 3111.
[0065] The first mounting plate 312 is arranged on the second linear moving member 313, and the second linear moving member 313 can drive the first mounting plate 312 to move towards the first mounting position.
[0066] Exemplarily, both the first mounting position and the third mounting position are located on the moving path of the second linear moving member 313.
[0067] Exemplarily, the second linear moving member 313 includes two second slide rails which are arranged at intervals along the axial direction D1, and each second slide rail extends along the first direction D2 from the first installation position to the third installation position. Both ends of the first mounting plate 312 along the axial direction D1 are respectively slidably connected to the two second sliders. Further, the second linear moving member 313 further includes a chain conveyor. The end of the first mounting plate 312 close to the second slide rail is connected to the chain of the chain conveyor. The driving motor drives the chain to move, thereby driving the first mounting plate 312 to slide along the second slide rail.
[0068] The first installation position can be adjusted accordingly according to the diameter of the core 101 and the thickness of the cotton wrapping sheet 102.
[0069] When the diameter of the core 101 becomes smaller or the thickness of the cotton wrapping sheet 102 becomes thinner, in order to facilitate abutting the core 101 against the cotton wrapping sheet 102 at the feeding side 211, the first installation position can be appropriately moved a distance along the first direction D2 closer to the feeding side 211.
[0070] Similarly, when the diameter of the core 101 becomes larger or the thickness of the cotton wrapping sheet 102 becomes thicker, the first installation position can be moved a certain distance along the first direction D2 away from the feeding side 211.
[0071] Further, a first sensor 34 can be provided at the first installation position of the second linear moving member 313. For the structure of the first sensor 34, please refer to Figure 4 .
[0072] When the second linear moving member 313 drives the first mounting plate 312 to move to the first sensor 34, the first sensor 34 sends a signal to the first driving member 33, and the first driving member 33 drives the air chuck 32 to rotate, thereby driving the core 101 to rotate for cotton wrapping.
[0073] Exemplarily, the first sensor 34 is movably fixed to the second linear moving member 313. When the diameter of the core 101 or the thickness of the cotton wrapping sheet 102 changes, the first sensor 34 can be adaptively moved and fixed to the second linear moving member.
[0074] Exemplarily, a mounting seat is provided at one end of the first mounting plate 312 away from the first linear moving member 311, and the first driving member 33 is rotatably connected to the air chuck 32 through the mounting seat.
[0075] Exemplarily, the first driving member 33 can be selected from a motor.
[0076] Generally, the width of the cotton wrapping sheet 102 perpendicular to the axial direction D1 is greater than the circumference of the core. Therefore, when using the cotton wrapping mechanism 20 to wrap the core 101, as Figure 5As shown, surplus wrapping cotton sheets 102 will be formed at the starting and ending positions of the core 101. Therefore, it is necessary to cut the cutting position 103.
[0077] Furthermore, the core wrapping cotton device 1 provided by the example of the present application can also be provided with a cutting mechanism 40 for cutting the cutting position 103 of the wrapping cotton sheet 102 after wrapping by the wrapping cotton mechanism 20.
[0078] Exemplarily, there is also a second installation position at the machine table of the frame 10. Please refer to Figure 6 , the cutting mechanism 40 includes a second moving component 41 and a tool 42 arranged above the second installation position. The second moving component 41 can selectively drive the tool to move up and down to abut against the cutting position 103 of the wrapping cotton sheet 102, and drive the tool 42 to move along the axial direction D1 of the core 101 to cut the cutting position 103. The position where the second moving component 41 in the cutting mechanism 40 is located directly opposite to the machine table is the second installation position. The second installation position and the first installation position are arranged at intervals, that is, the cutting mechanism 40 and the wrapping cotton mechanism 20 are arranged at intervals.
[0079] Furthermore, in some possible embodiments, the second installation position is located on the movement path of the second linear moving member 313. The second linear moving member 313 moves the wrapped core 101 from the first installation position to the second installation position, and then the second moving component 41 drives the tool 42 to abut against the cutting position 103 of the wrapping cotton sheet 102 and slide along the axial direction D1 to cut the cutting position 103.
[0080] Exemplarily, when the second linear moving member 313 drives the core 101 to move below the third linear moving member 412, the first driving member 33 can drive the air chuck 32 to rotate to rotate the cutting position 103 to be directly below the tool 42.
[0081] Furthermore, please continue to refer to Figure 6 , the second moving component 41 can include two lifting members 411 arranged at intervals at the second installation position, and a third linear moving member 412. The two lifting members 411 are arranged at intervals along the axial direction D1, and the first moving component 31 is located between the two lifting members 411; the two lifting members 411 are respectively connected to the third linear moving member 412 for driving the third linear moving member 412 to move up and down; the third linear moving member 412 is connected to the tool 42 for driving the tool 42 to slide along the axial direction D1.
[0082] Exemplarily, the lifting member 411 can be a lifting cylinder.
[0083] Furthermore, in some possible embodiments, please continue to refer to Figure 6, a second sensor 43 can be provided on the side of the lifting member 411 facing the core 101.
[0084] The third sensor 44 can sense whether the core 101 has moved between the two lifting members 411 and below the third linear moving member 412. When the second sensor 43 senses the core 101, the second sensor 43 can send a signal to the lifting member 411 to control the lifting member 411 to drive the third linear moving member 412 to descend, so that the cutter 42 slides along the cutting position 103.
[0085] Exemplarily, the second sensor 43 can be selected from a spot sensor.
[0086] Furthermore, the third linear moving member 412 drives the cutter 42 to slide from the first end 4121 to the second end 4122. The cutting mechanism 40 further includes a third sensor 44, and the third sensor 44 is disposed at the second end 4122; when the third linear moving member 412 drives the cutter 42 to slide from the first end 4121 to the second end 4122, the third sensor 44 can send a signal to the lifting member 411, and the lifting member 411 moves upward to move the cutter 42 away from the core 101.
[0087] Furthermore, the third sensor 44 is signal-connected to the second linear moving member 313. When the third sensor 44 senses that the cutter 42 has moved to the second end 4122, the third sensor 44 sends a signal to the second linear moving member 313, and the second linear moving member 313 drives the cut core 101 to move to the third installation position to facilitate the operator to pick up and place the core 101.
[0088] Furthermore, please continue to refer to Figure 6 , the third linear moving member 412 can be disposed on the second mounting plate 45, and the second mounting plate 45 is connected to the lifting member 411.
[0089] The second mounting plate 45 has a strip-shaped hollow portion 451 extending along the axial direction D1, and the cutter 42 passes through the hollow portion 451 and extends below the second mounting plate 45. The cutting mechanism 40 further includes two pressing blocks 46, and the two pressing blocks 46 are disposed on both sides of the hollow portion 451 at the bottom of the second mounting plate 45, so that the cutter 42 is located between the two pressing blocks 46. When the lifting member 411 moves downward to make the cutter 42 abut against the cutting position 103 of the cotton wrapping sheet 102, please refer to Figure 7 , the two pressing blocks 46 are pressed against both sides of the cutting position 103.
[0090] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. 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.
