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

[0036] The rotating shaft disassembly and assembly device 10 includes a frame 11, a tensioning structure 12, an abutting structure 13, a transmission belt 14 and a driving structure 15. The tensioning structure 12 is mounted on the frame 11. The abutting structure 13 includes a moving seat 131 and at least two abutting wheels 132. The moving seat 131 is mounted on the frame 11 and is movably arranged relative to the frame 11. The moving direction of the moving seat 131 relative to the frame 11 and the sliding direction of the tensioning structure 12 relative to the frame 11 are arranged at an angle. All the abutting wheels 132 are connected to the moving seat 131, and different abutting wheels 132 are arranged at intervals. The transmission belt 14 is used to drive and connect the tensioning structure 12 and all the abutting wheels 132 together. The tensioning structure 12 is used to keep the transmission belt 14 tensioned. The driving structure 15 is connected to the transmission belt 14 in a transmission manner and is used to drive the transmission belt 14 to rotate. The rotating shaft 212 is located between two adjacent abutting wheels 132.

[0037] Please also read Figure 1 and Figure 2 When the movable seat 131 moves to the first position of the frame 11, the contact wheel 132 drives the transmission belt 14 to be in transmission connection with the rotating shaft 212. The driving structure 15 drives the rotating shaft 212 to rotate through the transmission belt 14.

[0038] Please also read Figure 1 and Figure 3When the movable seat 131 moves to the second position of the frame 11, the contact 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 disassembly and assembly device 10. When reinstalling the rotating shaft 212 and the slitting piece 211, the rotating shaft 212 is placed between two adjacent contact wheels 132, and the movable seat 131 moves to the first position of the frame 11. The contact wheel 132 drives the transmission belt 14 to be connected to the rotating shaft 212, thereby completing the installation of the rotating shaft 212 and the slitting piece 211.

[0039] In the embodiment of the present application, 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, and 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 tensioned state at all times. When the shaft 212 is disassembled and assembled, the shaft 212 can be removed from the shaft disassembly and assembly device 10 or placed between two adjacent abutment wheels 132 to achieve disassembly or installation of the shaft 212, which greatly simplifies the disassembly and assembly process of the shaft 212 and improves the disassembly and assembly efficiency of the shaft 212, thereby improving the production efficiency of the slitting equipment 100.

[0040] The abutment wheel 132 is movable relative to the moving seat 131, and / or the tensioning structure 12 is slidable relative to the frame 11. When the moving 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, so that the abutment wheel 132 moves relative to the moving seat 131 and / or the tensioning structure 12 moves relative to the frame 11, thereby changing the shape of the transmission belt 14, and then realizing that the abutment wheel 132 drives the transmission belt 14 to move. In the process of the movement of the transmission belt 14, the tensioning structure 12 always abuts against the transmission belt 14 to keep the transmission belt 14 tensioned.

[0041] Please also read Figure 1 , Figure 4 and Figure 5In the first embodiment of the present application, the tensioning structure 12 is slidably arranged 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 arranged 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 rotating shaft of the tensioning wheel 122 is passed through the mounting hole. The tensioning wheel 122 is rotatably connected to the tensioning seat 121. The tensioning wheel 122 is arranged in contact with the transmission belt 14. The tensioning wheel 122 is used to apply pressure to the transmission belt 14 to tighten the transmission belt 14, so as to avoid the transmission belt 14 from being loosened from the tensioning wheel 122, the abutting wheel 132 or the driving structure 15, resulting in the problem of transmission failure. Among them, the tensioning structure 12 can be set to one or more, and the number of the tensioning structures 12 can be specifically set according to actual needs, which is not specifically limited in the present application. For example, the tensioning structure 12 can be set to 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 through the sliding seat 123. When the abutting 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 further includes an elastic member 1241. The elastic member 1241 is elastically connected between the sliding seat 123 and the tensioning seat 121. The elastic member 1241 is used to apply an elastic force toward the transmission belt 14 to the tensioning seat 121, so that the tensioning wheel 122 is kept in contact with the transmission belt 14. The elastic member 1241 can be configured as a spring, a torsion spring, an elastic body made of an elastic material, etc.

[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 is provided with a guide hole, and the guide post 1211 is inserted into the guide hole. Exemplarily, the tensioning seat 121 is fixedly connected to the guide post 1211, and the sliding seat 123 is provided with a guide hole. The guide post 1211 is slidably connected to the sliding seat 123. The elastic member 1241 can be sleeved on the guide post 1211 to make the structure of the tensioning structure 12 compact and improve the space utilization. Among them, the guide post 1211 can be set to two, and the central axes of the two guide posts 1211 are set in parallel to prevent the tensioning seat 121 from rotating. The elastic member 1241 is correspondingly set to two. In some embodiments, a linear bearing 1212 is provided on the sliding seat 123, and the guide post 1211 is inserted into the linear bearing 1212 to reduce sliding resistance and reduce wear.

[0045] The rotating shaft disassembly and assembly device 10 also includes a first slide rail 1111 installed on the frame 11. The tensioning structure 12 is slidably connected to the first slide rail 1111. Among them, the tensioning structure 12 also includes a first slider 1112. The first slider 1112 is slidably matched with the first slide rail 1111. The 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 through the guide column 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 slidable 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 toward the sliding seat 123 is restricted. The slidable stroke of the tensioning seat 121 relative to the sliding seat 123 can be adjusted by adjusting the protruding length of the screw 1251 relative to the tensioning seat 121. Among them, when the abutment wheel 132 moves to the first position, the adjusting screw 1251 is arranged to abut against the sliding seat 123. At this time, the abutment wheel 132 and the transmission belt 14 are kept in abutment, and the tensioning force of the transmission belt 14 can be provided by the tensioning wheel 122 and the abutment wheel 132. In this way, on the one hand, the transmission belt 14 can always be kept tensioned during the movement of the moving seat 131, and on the other hand, when the moving seat 131 moves to the first position, the position of the tensioning wheel 122 can be fixed relative to the transmission belt 14 to avoid fluctuations in the tensioning force of the transmission belt 14, thereby improving the transmission stability and reliability of the driving structure 15 and the rotating shaft 212 and improving the transmission accuracy. 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 tensioning wheel 122 and the abutting wheel 132 are respectively configured as synchronous pulleys that match the transmission belt to improve the transmission accuracy between the driving structure 15 and the rotating shaft 212. Synchronous pulleys that match the synchronous belt are respectively provided on the rotating shaft 212 and the driving structure 15. 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 can be fixed relative to the frame 11. When the abutting 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 arranged relative to the sliding seat 123, and the sliding seat 123 is slidably arranged relative to the frame 11. When the abutting 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 rotating shaft disassembly and assembly device 10 also includes an elastic abutment 1242, the tensioning structure 12 is slidable relative to the frame 11, one end of the elastic abutment 1242 is fixedly connected to the frame 11, and the other end of the elastic abutment 1242 elastically abuts against the tensioning structure 12. The elastic abutment 1242 is used to apply an elastic force toward the transmission belt 14 to the sliding seat 123, so that the tensioning wheel 122 and the transmission belt 14 remain in abutment. The elastic abutment 1242 can be configured as a spring, a torsion spring, an elastomer, etc. In some embodiments, the tensioning structure 12 and the elastic abutment member 1242 are respectively provided in number of two, and the two elastic abutment members 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. The elastic abutment member 1242 is elastically connected between the two tensioning structures 12, and the elastic abutment member 1242 is used to apply an elastic force toward the transmission belt 14 to the two tensioning structures 12, so that both tensioning structures 12 abut against the transmission belt 14.

[0051] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, two abutment wheels 132 are provided. One movable seat 131 is provided. The two abutment wheels 132 are provided on the same movable seat 131, so that when the movable seat 131 moves, the two abutment wheels 132 move synchronously, thereby improving the working stability of the rotating shaft disassembly and assembly device 10. Among them, an avoidance groove 1311 is provided on the movable seat 131. The two abutment wheels 132 are located on both sides of the avoidance groove 1311. The avoidance groove 1311 is used to accommodate the rotating shaft 212.

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

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

[0054] The rotating shaft disassembly and assembly device 10 further includes a second slide rail 1121 mounted on the frame 11. The moving 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 is slidably matched with the second slide rail 1121. The moving seat 131 is fixedly connected to the second slider 1122. The second slide rail 1121 can be provided in two, and the two second slide rails 1121 are provided in parallel to improve the stability of the moving seat 131 when sliding.

[0055] The rotating shaft disassembly and assembly device 10 further includes a driving member 134. The driving member 134 is mounted on the frame 11. The driving member 134 is used to drive the movable seat 131 to move between the first position and the second position. When the movable seat 131 is provided in plurality, the driving member 134 can be provided in plurality, and each driving member 134 is used to drive at least one movable seat 131 to move relative to the frame 11.

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

[0057] The linkage members 16 can be provided in two numbers, and the two linkage members 16 are respectively connected to the corresponding tensioning structures 12 for rotation. The two linkage members 16 are arranged in an eight-shaped shape. When the movable seat 131 moves toward the first position, the two linkage members 16 push the two tensioning structures 12 away from each other, and when the movable seat 131 moves toward the second position, the two linkage members 16 pull the two tensioning structures 12 toward each other. In this way, on the one hand, when the movable seat 131 moves, the tensioning structure 12 is driven to move together by the linkage member 16, so that the tensioning structure can move along with the change of the shape of the transmission belt 14, so that the tensioning force of the transmission belt 14 can change within a certain range, avoiding the tensioning force being too large or too small, and avoiding the tensioning force from changing too much, thereby increasing the service life of the transmission belt 14. On the other hand, it is possible to avoid setting an additional driver to drive the tensioning structure 12 to move, simplify the structure of the rotating shaft disassembly and assembly device 10, and reduce the manufacturing cost of the slitting equipment 100.

[0058] The tensioning structure 12 is slidably arranged relative to the frame 11. The sliding direction of the tensioning structure 12 relative to the frame 11 and the moving direction of the movable seat 131 relative to the frame 11 are arranged at an angle. 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 located away from the movable seat 131 and located on the side close to the tensioning structure 12 is an acute angle or a right angle. Exemplarily, the angle θ is a right angle. The extension direction of the second slide rail 1121 is arranged at a right angle to the extension direction of the first slide rail 1111. In this way, the first slide rail 1111 can be set as one, and the two tensioning structures 12 are both slidably connected to the first slide rail 1111. In this way, the structure of the rotating shaft disassembly and assembly device 10 can be simplified and the manufacturing cost can be reduced.

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

[0060] See also Figure 2 For example, two abutment wheels 132 are provided. Two tensioning structures 12 are provided. In the orthographic projection on the plane perpendicular to the central axis of the abutment wheel 132, the two tensioning structures 12 are symmetrically arranged relative to the perpendicular bisector of the line connecting the central axes of the two abutment wheels 132. In this way, when the movable seat 131 moves, the moving strokes of the two tensioning structures 12 relative to the frame 11 are the same, so that the tensioning forces acting on the transmission belt 14 by the two tensioning structures 12 and the variation of the tensioning forces are the same or similar, which is beneficial to improving the working stability of the rotating shaft disassembly and assembly device 10.

[0061] See also Fig. 9 , the extension direction of the linkage member 16 is set at an angle to the sliding direction of the tensioning structure 12 relative to the frame 11. The linkage member 16 is at least partially configured as an elastic portion, or an elastic structure 161 is provided between the linkage member 16 and the moving seat 131 and / or an elastic structure 161 is provided between the linkage member 16 and the tensioning structure 12. Exemplarily, an elastic structure 161 is provided between the linkage member 16 and the tensioning structure 12. The elastic structure 161 is used to apply an elastic force to the tensioning structure 12 in a direction away from the moving seat 131, so that the tensioning structure 12 abuts against the transmission belt 14. Among them, the elastic structure 161 can be configured as a spring, an elastomer, etc. In some embodiments, an elastic structure 161 is provided between the linkage member 16 and the moving seat 131. The elastic structure 161 is used to apply an elastic force to the linkage member 16 in a direction away from the moving seat 131, so that the linkage member 16 pushes the tensioning structure 12 to abut against the transmission belt 14. In some embodiments, elastic structures 161 are respectively provided between the linkage member 16 and the movable seat 131 and between the linkage member 16 and the tensioning structure 12. In some embodiments, a part of the structure or the whole of the linkage member 16 is configured as an elastic part, for example, the linkage member 16 can be configured as a spring.

[0062] See also Fig.10 , Fig.10 It is a schematic diagram of the structure of the rotating shaft disassembly and assembly device 10 provided in the second embodiment of the present application. The rotating shaft disassembly and assembly device 10 in the second embodiment is similar in structure to the rotating shaft disassembly and assembly device 10 in the first embodiment, except that the abutment wheel 132 is movably arranged 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 for the abutment seat 133 to apply an elastic force in the direction toward the transmission belt 14, so that the abutment wheel 132 remains in abutment with the transmission belt 14, thereby keeping the transmission belt 14 tensioned. In some embodiments, the abutment structure 13 also includes a guide column and an adjusting member. Among them, the structure of the guide column and the adjusting member may be similar to the structure of the guide column 1211 and the adjusting member 125 in the above-mentioned embodiment.

[0063] In some implementations of the second embodiment, the tension seat 121 is fixed relative to the sliding seat 123, and the sliding seat 123 is fixed relative to the frame 11. In some implementations of the second embodiment, the tension 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 rotating shaft disassembling and assembling device 10 may include one of the elastic member 1241, the elastic abutting member 1242, and the telescopic member 135, or at least two of the elastic member 1241, the elastic abutting member 1242, and the telescopic member 135. In this way, when the abutting wheel 132 drives the transmission belt 14 to move, the abutting wheel 132 and the tensioning wheel 122 can always keep in contact with the transmission belt 14, thereby preventing the transmission belt 14 from loosening.

[0065] In some embodiments, the slitting device 100 includes two slitting pieces 211, two rotating shafts 212, and two rotating shaft disassembling and assembling devices 10. Each slitting piece 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 disassembling and assembling device 10. Each slitting piece 211 is detachably connected to the corresponding rotating shaft disassembling and assembling device 10 through the corresponding rotating shaft 212.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application.
