The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] It should be noted that the terminology in the specification, claims, and accompanying drawings of this application is for describing specific embodiments only and is not intended to limit this application. The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. The term "and / or" as used in this application refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations.

[0035] See also Figure 1 , Figure 1 This is a schematic diagram of a portion of the structure of the slitting device 100 provided in this application embodiment. The slitting device 100 includes a slitting component 211, a rotating shaft 212, and a rotating shaft disassembly and assembly device 10. The slitting component 211 is connected to the rotating shaft 212. The slitting component 211 is detachably connected to the rotating shaft disassembly and assembly device 10 via the rotating shaft 212.

[0036] The shaft assembly / disassembly device 10 includes a frame 11, a tensioning structure 12, an abutment structure 13, a transmission belt 14, and a drive structure 15. The tensioning structure 12 is mounted on the frame 11. The abutment structure 13 includes a movable seat 131 and at least two abutment wheels 132. The movable seat 131 is mounted on the frame 11 and is movably disposed relative to the frame 11. The direction of movement of the movable seat 131 relative to the frame 11 forms an angle with the direction of sliding of the tensioning structure 12 relative to the frame 11. All abutment wheels 132 are connected to the movable seat 131, and are spaced apart. The transmission belt 14 is used to drive the tensioning structure 12 and all abutment wheels 132 together. The tensioning structure 12 is used to keep the transmission belt 14 taut. The drive structure 15 is driven by the transmission belt 14 and is used to drive the transmission belt 14 to rotate. The shaft 212 is located between two adjacent abutment wheels 132.

[0037] Please refer to the following: Figure 1 and Figure 2 When the movable seat 131 moves to the first position of the frame 11, the abutment wheel 132 drives the transmission belt 14 to drive the rotating shaft 212. The drive structure 15 drives the rotating shaft 212 to rotate through the transmission belt 14.

[0038] Please refer to the following: Figure 1 and Figure 3When the movable seat 131 moves to the second position of the frame 11, the abutment wheel 132 drives the transmission belt 14 to separate from the rotating shaft 212. At this time, the rotating shaft 212 and the slitting piece 211 can be removed from the rotating shaft removal and installation device 10. When reinstalling the rotating shaft 212 and the slitting piece 211, the rotating shaft 212 is placed between two adjacent abutment wheels 132, the movable seat 131 moves to the first position of the frame 11, and the abutment wheel 132 drives the transmission belt 14 to connect with the rotating shaft 212, thereby completing the installation of the rotating shaft 212 and the slitting piece 211.

[0039] In this embodiment, the shaft disassembly and assembly device 10 is based on the movement of the movable seat 131 between the first position and the second position. The abutment wheel 132 drives the transmission belt 14 to separate from or connect with the shaft 212. When the abutment wheel 132 drives the transmission belt 14 to move, the tensioning structure 12 keeps the transmission belt 14 in a taut state. When disassembling and assembling the shaft 212, the shaft 212 can be removed from the shaft disassembly and assembly device 10 or placed between two adjacent abutment wheels 132 to achieve the disassembly or installation of the shaft 212. This greatly simplifies the disassembly and assembly process of the shaft 212, improves the disassembly and assembly efficiency of the shaft 212, and thus improves the production efficiency of the slitting equipment 100.

[0040] The abutment wheel 132 is movable relative to the movable seat 131, and / or the tensioning structure 12 is slidable relative to the frame 11. When the movable seat 131 moves relative to the frame 11, the abutment wheel 132 applies a force to the transmission belt 14, and the transmission belt 14 generates a reaction force on the abutment wheel 132 and the tensioning structure 12, causing the abutment wheel 132 to move relative to the movable seat 131 and / or the tensioning structure 12 to move relative to the frame 11. This changes the shape of the transmission belt 14, thereby enabling the abutment wheel 132 to drive the transmission belt 14 to move. During the movement of the transmission belt 14, the tensioning structure 12 remains in contact with the transmission belt 14 to maintain tension.

[0041] Please refer to the following: Figure 1 , Figure 4 and Figure 5In the first embodiment of this application, the tensioning structure 12 is slidably disposed relative to the frame 11. The tensioning structure 12 includes a tensioning seat 121 and a tensioning wheel 122. The tensioning seat 121 is slidably disposed relative to the frame 11. The tensioning wheel 122 is connected to the tensioning seat 121. A mounting hole may be provided on the tensioning seat 121, and the rotation shaft of the tensioning wheel 122 passes through the mounting hole. The tensioning wheel 122 is rotatably connected to the tensioning seat 121. The tensioning wheel 122 abuts against the transmission belt 14. The tensioning wheel 122 is used to apply pressure to the transmission belt 14, so that the transmission belt 14 is taut, and to prevent the transmission belt 14 from becoming loose from the tensioning wheel 122, the abutting wheel 132 or the drive structure 15, which would lead to transmission failure. The tensioning structure 12 can be one or more, and the number of tensioning structures 12 can be specifically set according to actual needs. This application does not make a specific limitation; for example, the tensioning structure 12 can be one, two, three, four, etc.

[0042] In some embodiments, the tensioning structure 12 further includes a sliding seat 123. The tensioning seat 121 is slidably disposed relative to the sliding seat 123, and the sliding seat 123 is slidably disposed relative to the frame 11. The tensioning seat 121 is slidable relative to the frame 11 via the sliding seat 123. When the abutment wheel 132 drives the transmission belt 14 to move, the transmission belt 14 pushes the tensioning wheel 122 to move, and the tensioning wheel 122 drives the tensioning seat 121 and the sliding seat 123 to slide relative to the frame 11.

[0043] The tensioning structure 12 also includes an elastic element 1241. The elastic element 1241 is elastically connected between the sliding seat 123 and the tensioning seat 121. The elastic element 1241 applies an elastic force to the tensioning seat 121 in the direction of the drive belt 14, so that the tensioning pulley 122 remains in contact with the drive belt 14. The elastic element 1241 can be configured as a spring, torsion spring, or an elastomer made of an elastic material.

[0044] In some embodiments, the tensioning structure 12 further includes a guide post 1211. One of the tensioning seat 121 and the sliding seat 123 is fixedly connected to the guide post 1211, and the other has a guide hole in which the guide post 1211 passes. Exemplarily, the tensioning seat 121 is fixedly connected to the guide post 1211, and the sliding seat 123 has a guide hole. The guide post 1211 is slidably connected to the sliding seat 123. An elastic element 1241 can be sleeved on the guide post 1211 to make the tensioning structure 12 compact and improve space utilization. Two guide posts 1211 can be provided, with their central axes parallel to each other to prevent rotation of the tensioning seat 121. Two corresponding elastic elements 1241 are also provided. In some embodiments, a linear bearing 1212 is provided on the sliding seat 123, and the guide post 1211 passes through the linear bearing 1212 to reduce sliding resistance and wear.

[0045] The rotating shaft assembly / disassembly device 10 also includes a first slide rail 1111 mounted on the frame 11. A tensioning structure 12 is slidably connected to the first slide rail 1111. The tensioning structure 12 further includes a first slider 1112. The first slider 1112 is slidably engaged with the first slide rail 1111. A sliding seat 123 is fixedly connected to the first slider 1112. The sliding seat 123 includes a first seat body 1231 and a second seat body 1232. The first seat body 1231 and the second seat body 1232 are connected in an L-shape. The second seat body 1232 is fixedly connected to the first slider 1112. The tensioning seat 121 is slidably connected to the first seat body 1231 via a guide post 1211.

[0046] The tensioning structure 12 also includes an adjusting member 125. The adjusting member 125 is disposed on the sliding seat 123. The adjusting member 125 is used to adjust the sliding stroke of the tensioning seat 121 relative to the sliding seat 123. The adjusting member 125 includes an adjusting screw 1251 and an adjusting nut 1252. The adjusting screw 1251 is threadedly connected to the tensioning seat 121. The adjusting nut 1252 is threadedly connected to the adjusting screw 1251. The adjusting nut 1252 is used to fix the adjusting screw 1251 to the tensioning seat 121 to prevent the adjusting screw 1251 from loosening. When the end of the adjusting screw 1251 away from the tensioning seat 121 abuts against the sliding seat 123, the sliding of the tensioning seat 121 towards the sliding seat 123 is restricted. The sliding stroke of the tensioning seat 121 relative to the sliding seat 123 can be adjusted by adjusting the extension length of the adjusting screw 1251 relative to the tensioning seat 121. In this configuration, when the abutment wheel 132 moves to the first position, the adjusting screw 1251 abuts against the sliding seat 123. At this time, the abutment wheel 132 maintains contact with the transmission belt 14, and the tension of the transmission belt 14 can be provided jointly by the tensioning wheel 122 and the abutment wheel 132. This ensures that the transmission belt 14 remains taut throughout the movement of the moving seat 131, and that the position of the tensioning wheel 122 relative to the transmission belt 14 is fixed when the moving seat 131 moves to the first position, preventing fluctuations in the tension of the transmission belt 14. This improves the transmission stability, reliability, and transmission accuracy of the drive structure 15 and the rotating shaft 212. In some embodiments, the adjusting screw 1251 can be threadedly connected to the sliding seat 123, and the adjusting nut 1252 is used to fix the adjusting screw 1251 to the sliding seat 123.

[0047] The transmission belt 14 can be configured as a synchronous belt, and the tension pulley 122 and the abutment pulley 132 are respectively configured as synchronous pulleys that cooperate with the transmission belt to improve the transmission accuracy between the drive structure 15 and the rotating shaft 212. The rotating shaft 212 and the drive structure 15 are respectively provided with synchronous pulleys that cooperate with the synchronous belt. In some embodiments, the transmission belt 14 can also be configured as other types of transmission belts.

[0048] In some embodiments, the tensioning seat 121 is slidably disposed relative to the sliding seat 123, and the sliding seat 123 is fixedly disposed relative to the frame 11. When the abutment wheel 132 drives the transmission belt 14 to move, the transmission belt 14 pushes the tensioning wheel 122 to move, and the tensioning wheel 122 drives the tensioning seat 121 to slide relative to the sliding seat 123.

[0049] See also Figure 6 In some embodiments, the tensioning seat 121 is fixedly disposed relative to the sliding seat 123, and the sliding seat 123 is slidably disposed relative to the frame 11. When the abutment wheel 132 drives the transmission belt 14 to move, the transmission belt 14 pushes the tensioning wheel 122 and the tensioning seat 121 to move, and the tensioning seat 121 drives the sliding seat 123 to slide relative to the frame 11. In some embodiments, the shaft disassembly and assembly device 10 further includes an elastic abutment member 1242. The tensioning structure 12 is slidable relative to the frame 11, one end of the elastic abutment member 1242 is fixedly connected to the frame 11, and the other end of the elastic abutment member 1242 elastically abuts against the tensioning structure 12. The elastic abutment member 1242 is used to apply an elastic force to the sliding seat 123 in the direction of the transmission belt 14, so that the tensioning wheel 122 and the transmission belt 14 remain in contact. The elastic abutment member 1242 can be configured as a spring, torsion spring, elastomer, etc. In some embodiments, the tensioning structure 12 and the elastic abutment 1242 are each provided as two, and the two elastic abutments 1242 are elastically abutted between the corresponding tensioning structure 12 and the frame 11.

[0050] See also Figure 7 In some embodiments, two tensioning structures 12 are provided. Both tensioning structures 12 are slidable relative to the frame 11. An elastic abutment 1242 is elastically connected between the two tensioning structures 12, and the elastic abutment 1242 is used to apply an elastic force to the two tensioning structures 12 in the direction toward the drive belt 14, so that both tensioning structures 12 abut against the drive belt 14.

[0051] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, two abutment wheels 132 are provided, and one movable base 131 is provided. The two abutment wheels 132 are mounted on the same movable base 131, so that when the movable base 131 moves, the two abutment wheels 132 move synchronously, improving the working stability of the rotating shaft assembly / disassembly device 10. The movable base 131 has a clearance groove 1311. The two abutment wheels 132 are located on both sides of the clearance groove 1311. The clearance groove 1311 is used to accommodate the rotating shaft 212.

[0052] The number of abutment wheels 132 can be specifically set according to actual needs, and is not specifically limited in this application. For example, the abutment wheels 132 can also be three, four, etc. The movable seat 131 can be one or more. In some embodiments, the movable seat 131 can be multiple, and each movable seat 131 is provided with at least one abutment wheel 132.

[0053] The abutment structure 13 also includes an abutment seat 133. An abutment wheel 132 is rotatably connected to the abutment seat 133. Exemplarily, the abutment seat 133 is fixedly connected to the movable seat 131.

[0054] The rotating shaft assembly / disassembly device 10 also includes a second slide rail 1121 mounted on the frame 11. The movable seat 131 is slidably connected to the second slide rail 1121. The abutment structure 13 further includes a second slider 1122. The second slider 1122 slidably engages with the second slide rail 1121. The movable seat 131 is fixedly connected to the second slider 1122. Two second slide rails 1121 can be provided, arranged parallel to each other to improve the stability of the movable seat 131 during sliding.

[0055] The shaft mounting / dismounting device 10 also includes a drive element 134. The drive element 134 is mounted on the frame 11. The drive element 134 is used to drive the movable seat 131 to move between a first position and a second position. When there are multiple movable seats 131, there can be multiple drive elements 134, each drive element 134 being used to drive at least one movable seat 131 to move relative to the frame 11.

[0056] The rotating shaft assembly / disassembly device 10 also includes a linkage 16. One end of the linkage 16 is rotatably connected to the movable seat 131, and the other end of the linkage 16 is rotatably connected to the sliding seat 123 in the tensioning structure 12. When the movable seat 131 moves between the first position and the second position, the linkage 16 drives the tensioning structure 12 to slide relative to the frame 11, so that the tensioning structure 12 remains in contact with the transmission belt 14.

[0057] Two linkages 16 can be configured, each rotatably connected to a corresponding tensioning structure 12. The two linkages 16 are arranged in a V-shape. When the movable seat 131 moves to the first position, the two linkages 16 push the two tensioning structures 12 away from each other; when the movable seat 131 moves to the second position, the two linkages 16 pull the two tensioning structures 12 closer together. Thus, on the one hand, when the movable seat 131 moves, the tensioning structures 12 move along with it via the linkages 16, allowing the tensioning structures to move with the shape of the transmission belt 14, thus varying the tension of the transmission belt 14 within a certain range. This avoids excessive or insufficient tension and excessive fluctuations in tension, thereby improving the service life of the transmission belt 14. On the other hand, it eliminates the need for an additional driver to move the tensioning structures 12, simplifying the structure of the shaft disassembly and assembly device 10 and reducing the manufacturing cost of the slitting equipment 100.

[0058] The tensioning structure 12 is slidably disposed relative to the frame 11. The sliding direction of the tensioning structure 12 relative to the frame 11 forms an angle with the moving direction of the movable seat 131 relative to the frame 11. In the angle formed by the sliding direction of the tensioning structure 12 and the moving direction of the movable seat 131, the angle θ on the side away from the movable seat 131 and close to the tensioning structure 12 is an acute angle or a right angle. For example, the angle θ is a right angle. The extending direction of the second slide rail 1121 is perpendicular to the extending direction of the first slide rail 1111. Thus, the first slide rail 1111 can be configured as one, and both tensioning structures 12 are slidably connected to the first slide rail 1111. This simplifies the structure of the rotating shaft assembly / disassembly device 10 and reduces manufacturing costs.

[0059] See also Figure 8 In some embodiments, the included angle θ can also be an acute angle to reduce the angle between the extension direction of the linkage 16 and the sliding direction of the tensioning structure 12 when the movable seat 131 moves, thereby increasing the component force of the linkage 16 acting on the tensioning structure 12 along the sliding direction of the tensioning structure 12, which helps to reduce the moving resistance of the movable seat 131 and improve the assembly and disassembly efficiency of the rotating shaft 212.

[0060] See also Figure 2 For example, two abutment wheels 132 are provided. Two tensioning structures 12 are also provided. Projected onto a plane perpendicular to the central axis of the abutment wheel 132, the two tensioning structures 12 are symmetrically arranged with respect to the perpendicular bisector of the line connecting the central axes of the two abutment wheels 132. Thus, when the moving seat 131 moves, the two tensioning structures 12 have the same travel relative to the frame 11, ensuring that the tension force exerted by the two tensioning structures 12 on the transmission belt 14 and the change in tension force are the same or similar, which is beneficial for improving the working stability of the shaft assembly / disassembly device 10.

[0061] See also Figure 9 The extension direction of the linkage 16 forms an angle with the sliding direction of the tensioning structure 12 relative to the frame 11. The linkage 16 is at least partially configured as an elastic portion, or an elastic structure 161 is provided between the linkage 16 and the movable seat 131 and / or between the linkage 16 and the tensioning structure 12. Exemplarily, an elastic structure 161 is provided between the linkage 16 and the tensioning structure 12. The elastic structure 161 applies an elastic force to the tensioning structure 12 in a direction away from the movable seat 131, causing the tensioning structure 12 to abut against the transmission belt 14. The elastic structure 161 can be configured as a spring, an elastic body, etc. In some embodiments, an elastic structure 161 is provided between the linkage 16 and the movable seat 131. The elastic structure 161 applies an elastic force to the linkage 16 in a direction away from the movable seat 131, causing the linkage 16 to push the tensioning structure 12 to abut against the transmission belt 14. In some embodiments, elastic structures 161 are provided between the linkage 16 and the movable seat 131, and between the linkage 16 and the tensioning structure 12. In some embodiments, part or all of the linkage 16 is configured as an elastic part; for example, the linkage 16 may be configured as a spring.

[0062] See also Figure 10 , Figure 10 This is a schematic diagram of the structure of the shaft disassembly and assembly device 10 provided in the second embodiment of this application. The shaft disassembly and assembly device 10 in the second embodiment is similar in structure to that in the first embodiment, except that the abutment wheel 132 is movably disposed relative to the movable seat 131. The abutment structure 13 also includes a telescopic member 135. The telescopic member 135 is elastically connected between the movable seat 131 and the abutment seat 133. The telescopic member 135 is used to apply an elastic force to the abutment seat 133 in the direction toward the transmission belt 14, so that the abutment wheel 132 keeps abutting against the transmission belt 14, thereby keeping the transmission belt 14 taut. In some embodiments, the abutment structure 13 also includes a guide post and an adjusting member. The structure of the guide post and the adjusting member can be similar to the structure of the guide post 1211 and the adjusting member 125 in the above embodiment.

[0063] In some embodiments of the second embodiment, the tensioning seat 121 is fixedly disposed relative to the sliding seat 123, and the sliding seat 123 is fixedly disposed relative to the frame 11. In some embodiments of the second embodiment, the tensioning seat 121 is slidable relative to the sliding seat 123, and / or the sliding seat 123 is slidable relative to the frame 11.

[0064] The shaft disassembly and assembly device 10 may include one of the elastic element 1241, the elastic abutment element 1242, and the telescopic element 135, or at least two of the elastic element 1241, the elastic abutment element 1242, and the telescopic element 135. Thus, when the abutment wheel 132 drives the transmission belt 14 to move, the abutment wheel 132 and the tension wheel 122 can always maintain contact with the transmission belt 14, thereby preventing the transmission belt 14 from becoming loose.

[0065] In some embodiments, the slitting device 100 includes two slitting components 211, two rotating shafts 212, and two rotating shaft disassembly / reassembly devices 10. Each slitting component 211 is connected to a corresponding rotating shaft 212. Each rotating shaft 212 is located between two adjacent abutment wheels 132 in the corresponding rotating shaft disassembly / reassembly device 10. Each slitting component 211 is detachably connected to the corresponding rotating shaft disassembly / reassembly device 10 via the corresponding rotating shaft 212.

[0066] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
