[0021] Please refer to Figures 1 to 8 As shown, a conveniently disassembled and assembled rolling device 100 of the present invention, the rolling device 100 includes: Rolling roller 1, which is used to wind a cutting wire and drive the cutting wire to move during use to achieve a cutting function; Fitting 2, fittings 2 are provided at both ends of the rolling roller 1; the fitting 2 extends outward along the axial direction and is provided with a threaded section 21, and an abutting slot hole 22 is formed at one end of the threaded section 21 away from the rolling roller 1; The tightening assembly 3, each of the fitting assemblies 2 is connected with a tightening assembly 3. The connection between the tightening assembly 3 and the fitting assembly 2 is detachable, so as to realize the disassembly and replacement of the roller 1 by the detachable separation between the tightening assembly 3 and the fitting assembly 2. The tightening assembly 3 includes an assembly main body 31 and a pressing main body 32 rotatably arranged on the assembly main body 31. A pressing plug 321 inserted into the pressing slot hole 22 is arranged at one end of the pressing main body 32 close to the fitting assembly 2. A nut member 4 is rotatably arranged outside the pressing plug 321, and the nut member 4 is threadedly connected with the threaded section 21. When disassembling the roller 1, it is necessary to loosen the nut member 4 in the direction away from the fitting assembly 2, so that the nut member 4 is disengaged from the threaded section 21, and at the same time, the pressing plug 321 is disengaged from the pressing slot hole 22. When assembling the roller 1, it is necessary to insert the pressing plug 321 into the pressing slot hole 22 and tighten the nut member 4 in the direction close to the fitting assembly 2, so that the nut member 4 is screwed tightly with the threaded section 21. The driving mechanism 5, the driving mechanism 5 is connected with the pressing main body 32 of any one of the tightening assemblies 3, so as to drive the pressing main body 32 to rotate through the driving mechanism 5, and then drive the fitting assembly 2 and the roller 1 to rotate together through the pressing main body 32. The driving mechanism 5 is specifically a driving motor. The support frame 6, the support frame 6 is used to support the roller 1. The assembly main body 31 of the tightening assembly 3 at the end far from the driving mechanism 5 is connected with the support frame 6 through a tightening and loosening structure 7. During use, only need to loosen the tightening and loosening structure 7, then the nut member 4 can be operated to disassemble and separate the tightening assembly 3 from the fitting assembly 2.

[0022] In the present invention, fitting members 2 having threaded sections 21 and abutting slot holes 22 are provided at both ends of the roller 1, and each fitting member 2 is detachably connected with a tightening assembly 3. The tightening assembly 3 is designed to include an assembly main body 31 and an abutting main body 32 rotatably arranged on the assembly main body 31. An abutting plug 321 for inserting into the abutting slot hole 22 is provided at one end of the abutting main body 32, and a nut member 4 is rotatably arranged outside the abutting plug 321. The driving mechanism 5 is connected to the abutting main body 32 of one of the tightening assemblies 3, and at the same time, the assembly main body 31 at the end far from the driving mechanism 5 is connected to the support frame 6 through a tightening and loosening structure 7. During the specific use process, when the roller 1 needs to be disassembled and replaced, only the tightening and loosening structure 7 at the end far from the driving mechanism 5 needs to be loosened, and the nut member 4 at the end far from the driving mechanism 5 is rotated to separate the abutting plug 321 and the nut member 4 on the tightening assembly 3 from the threaded section 21 and the abutting slot hole 22 on the fitting member 2, so that the tightening assembly 3 at the end far from the driving mechanism 5 is completely separated from the roller 1. Then, the nut member 4 at the end close to the driving mechanism 5 is rotated to separate the abutting plug 321 and the nut member 4 on the tightening assembly 3 from the threaded section 21 and the abutting slot hole 22 on the fitting member 2, and the roller 1 can be disassembled from the support frame 6 without disassembling the driving mechanism 5 and the two tightening assemblies 3 together. At the same time, when reinstalling the roller 1, only the roller 1 needs to be hoisted onto the support frame 6, the abutting plugs 321 on the two tightening assemblies 3 are inserted into the corresponding abutting slot holes 22 of the fitting members 2, the nut members 4 on the two tightening assemblies 3 are screwed tightly with the threaded sections 21 of the corresponding fitting members 2 together, and at the same time, the assembly main body 31 of the tightening assembly 3 is locked with the support frame 6 by using the tightening and loosening structure 7 at the end far from the driving mechanism 5. Therefore, by adopting the technical solution of the present invention, it is possible to achieve that only the roller 1 needs to be disassembled and assembled during disassembly and replacement, without disassembling the driving mechanism 5 and the two tightening assemblies 3 together. The whole disassembly and replacement process is simpler and more convenient, and the disassembly and replacement efficiency of the roller 1 can be improved.

[0023] In the present invention, in order to improve the stability of the fitting member 2 and the tightening assembly 3 after assembly, the abutting slot hole 22 is a tapered slot hole that gradually narrows from outside to inside, and the abutting plug 321 is a tapered plug that matches the tapered slot hole.

[0024] In the present invention, as Figure 3As shown, the nut member 4 includes a main nut 41 rotatably arranged on the abutting main body 32 and an auxiliary nut 42 threadedly connected to the threaded section 21. By rotatably arranging the main nut 41 on the abutting main body 32, the fitting 2 and the tightening assembly 3 can be more reliably connected together after assembly. At the same time, by screwing the auxiliary nut 42 onto the threaded section 21, after the main nut 41 is screwed tightly with the threaded section 21, the auxiliary nut 42 can be rotated to tighten the main nut 41, so as to improve the assembly stability. Of course, in the specific implementation of the present invention, the auxiliary nut 42 may not be provided.

[0025] In the present invention, a first limiting groove 33 is formed between the end face of the abutting plug 321 and the end face of the assembly main body 31. The main nut 41 forms a first limiting convex ring 411 inward along the radial direction at one end close to the assembly main body 31, and the first limiting convex ring 411 is rotatably arranged in the first limiting groove 33. Through the structural design of the first limiting convex ring 411 and the first limiting groove 33, on the one hand, the main nut 41 can be limited to prevent the main nut 41 from detaching from the abutting plug 321; on the other hand, after the main nut 41 is screwed tightly with the threaded section 21, the abutting plug 321 can be tightened in the abutting groove hole 22 by using the first limiting convex ring 411, so that the abutting plug 321 can be tightly assembled with the threaded section 21, thus ensuring the use stability.

[0026] At least one second limiting groove 311 is annularly arranged on the end face of the assembly main body 31 facing the main nut 41. At least one second limiting convex ring 412 is formed on the end face of the main nut 41 facing the assembly main body 31, and the second limiting convex ring 412 is rotatably arranged in the second limiting groove 311. By adopting the structural design of the second limiting convex ring 412 and the second limiting groove 311, the main nut 41 can be further limited.

[0027] In the present invention, a third limiting convex ring 3211 is formed at one end of the abutting plug 321 close to the assembly main body 31, and the outer diameter of the third limiting convex ring 3211 is larger than the aperture of the abutting groove hole 22 to ensure that the abutting plug 321 can tightly abut against the threaded section 21.

[0028] In the present invention, as Figure 5As shown, the assembly main body 31 includes an assembly cylinder 312 and a sealing end plate 313 sealed at both ends of the assembly cylinder 312. The sealing end plate 313 is locked and connected to the assembly cylinder 312 by a plurality of first locking members 314. Specifically, bolts can be used to lock the sealing end plate 313 and the assembly cylinder 312 together; the push-up main body 32 has a transmission shaft 322 that extends into the assembly cylinder 312 or passes through the assembly main body 31. In the specific implementation of the present invention, when it is necessary to connect the push-up main body 32 with the drive mechanism 5, the transmission shaft 322 is passed through the assembly main body 31, and when the push-up main body 32 is not connected with the drive mechanism 5, the transmission shaft 322 is inserted into the assembly cylinder 312; the transmission shaft 322 is rotatably connected to the assembly cylinder 312 through a plurality of bearings 34, so that the transmission shaft 322 can rotate relative to the assembly cylinder 312 under the drive of the drive mechanism 5.

[0029] The present invention designs the assembly main body 31 to include an assembly cylinder 312 and sealing end plates 313 that are detachably sealed at both ends of the assembly cylinder 312, and the transmission shaft 322 that abuts the main body 32 is rotatably connected to the assembly cylinder 312 through bearings 34; so that during specific use, on the one hand, the assembly cylinder 312 can be used to install the roller 1 on the support frame 6, and the roller 1 can be rotated under the drive of the driving mechanism 5; on the other hand, the transmission shaft 322 and the bearing 34 can be conveniently installed in the assembly cylinder 312, and the sealing end plates 313 can be used to protect the internal structure.

[0030] In the present invention, the assembly bodies 31 of the two tightening assemblies 3 are connected to the support frame 6 via a tightening structure 7. The tightening structure 7 includes a clamping seat 71 fixed on the support frame 6 and a tightening member 72 cooperating with the clamping seat 71. The tightening member 72 tightens the assembly body 31 to the clamping seat 71 via a plurality of second locking members (not shown). Specifically, the tightening member 72 and the clamping seat 71 can be locked together by bolts, and the clamping seat 71 and the tightening member 72 cooperate to clamp the assembly cylinder 312 of the assembly body 31, so that the assembly cylinder 312 cannot rotate. The assembly body 31 is a cylindrical structure, so that the clamping seat 71 and the tightening member 72 can tighten the assembly cylinder 312 of the assembly body 31 more stably. The clamping seat 71 is integrally formed with the support frame 6 to ensure the support strength of the clamping seat 71.

[0031] The present invention designs an elastic structure 7 including a clamp seat 71 fixed on the support frame 6 and a tightening member 72 cooperating with the clamp seat 71, so that during actual use, the clamp seat 71 and the tightening member 72 can be used to reliably tighten the assembly cylinder 312 of the assembly body 31, thereby achieving a reliable installation of the roller roller 1 on the support frame 6; and the tightening member 72 can be conveniently loosened, thereby facilitating the disassembly, assembly and replacement of the roller roller 1.

[0032] In the present invention, the fitting 2 includes a fitting disc body 23. At one end of the fitting disc body 23 facing the roller 1, a positioning convex portion 231 is integrally formed along the axial direction. A positioning hole 11 is formed at the end of the roller 1. The positioning convex portion 231 is inserted into the positioning hole 11 to position the fitting disc body 23, so that the fitting 2 can be better combined with the end of the roller 1. The fitting disc body 23 is locked with the end of the roller 1 through a plurality of third locking members 24. A threaded section 21 is integrally formed at one end of the fitting disc body 23 away from the roller 1 to ensure the strength of the threaded section 21. Of course, when the present invention is specifically implemented, the positioning convex portion 231 may not be provided at one end of the fitting disc body 23 facing the roller 1.

[0033] In the present invention, as Figure 4 shown, the roller 1 includes a support shaft body 12 and a working layer 13 covering the outside of the support shaft body 12. The outer diameter of the fitting disc body 23 is equal to the outer diameter of the support shaft body 12. When the present invention is specifically implemented, the support shaft body 12 may specifically adopt a hollow shaft body. Since the fittings 2 for connecting with the jacking assembly 3 are provided at both ends of the roller 1, there is no need to further provide an intermediate core body for connection to the hollow shaft body. Therefore, the overall weight of the roller 1 can be effectively reduced. The working layer 13 specifically adopts a wear-resistant material to ensure that it is not easily worn during use and improve the service life, such as polyurethane rubber, etc. Embodiment 2

The disassembly and assembly method includes the following steps: During the first installation, the fittings 2 are installed at both ends of the roller 1 to combine the fittings 2 with the roller 1. The abutting plugs 321 on the two jacking assemblies 3 are respectively inserted into the corresponding abutting slot holes 22 of the fittings 2, and the nut members 4 on the jacking assemblies 3 are screwed tightly with the threaded sections 21 of the fittings 2. After screwing tightly, the abutting plugs 321 on the jacking assemblies 3 will abut against the fittings 2, so that the jacking assemblies 3 and the fittings 2 can be reliably connected together. The driving mechanism 5 is connected to the abutting main body 32 of one of the jacking assemblies 3, and the assembly main body 31 of the jacking assembly 3 is installed on the support frame 6 through the tightening and loosening structure 7. Specifically, the assembly main body 31 of the jacking assembly 3 is locked on the support frame 6 through the tightening and loosening structure 7 to support the roller 1 through the support frame 6. During disassembly, loosen the tension and relaxation structure 7 at the end away from the drive mechanism 5, and rotate the nut member 4 at the end away from the drive mechanism 5 to separate the abutting plug 321 on the abutting component 3 and the nut member 4 from the threaded section 21 and the abutting slot hole 22 on the fitting 2, that is, completely separate the abutting component 3 at the end away from the drive mechanism 5 from the roller 1; then rotate the nut member 4 at the end close to the drive mechanism 5 to separate the abutting plug 321 on the abutting component 3 and the nut member 4 from the threaded section 21 and the abutting slot hole 22 on the fitting 2, and the roller 1 can be disassembled from the support frame 6, so as to realize operations such as replacement and maintenance of the roller 1, and the drive mechanism 5 and the two abutting components 3 do not need to be disassembled; During reinstallation, hoist the roller 1 onto the support frame 6, insert the abutting plugs 321 on the two abutting components 3 into the corresponding abutting slot holes 22 of the fitting 2, and screw the nut members 4 on the two abutting components 3 together with the threaded sections 21 of the corresponding fittings 2. At the same time, use the tension and relaxation structure 7 at the end away from the drive mechanism 5 to lock the assembly body 31 of the abutting component 3 and the support frame 6 together. By adopting the technical solution of the present invention, it is possible to realize that only the roller 1 needs to be disassembled and assembled during disassembly and replacement, without disassembling the drive mechanism 5 and the two abutting components 3 together. The whole disassembly and replacement process is simpler and more convenient, and the disassembly and replacement efficiency of the roller 1 can be improved.
