DETAILED DESCRIPTION
[0025] As Figure 1 , Figures 3-5 shown, an environment-friendly biodegradable plastic bandage includes a belt 2 fixed on an annular paper tube 1, a belt cutting member 3, and a cutting member mounting plate 4. The cutting member mounting plate 4 has a circular connecting block 5 protruding from the middle part and inserted into the center of the annular paper tube 1. The circular connecting block 5 has an elastic support structure 6 on the circumferential surface and is connected to the annular paper tube 1 through the elastic support structure 6. The circular connecting block 5 is fixedly connected to a first connecting rod 7 arranged along the axial direction of the annular paper tube 1. The first connecting rod 7 is movably connected to a second connecting rod 8. The second connecting rod 8 is screwed with a threaded sleeve 9. The threaded sleeve 9 can be screwed and fixed with the end of the first connecting rod 7. The belt cutting member 3 is connected to the second connecting rod 8 and can rotate along the circumferential direction of the annular paper tube 1.
[0026] In the utility model, the cutting member mounting plate 4 can be fixed on the annular paper tube through the circular connecting block 5 and the elastic support structure 6 on the circular connecting block 5. The elastic support structure can adapt the cutting member mounting plate to paper tubes of various sizes. The belt cutting member 3 connected to the cutting member mounting plate 4 through the second connecting rod 8 and the first connecting rod 7 can conveniently cut the paper belt during use. The second connecting rod 8 and the first connecting rod 7 are movably connected and can be adjusted in length to adjust the position of the belt cutting member. The second connecting rod 8 and the first connecting rod 7 can be fixed through the threaded sleeve to fix the position of the belt cutting member.
[0027] Specifically, the belt cutting member 3 includes a cutting part 10 and a connecting part 11. The connecting part 11 is rotatably connected to the second connecting rod 8. The cutting part 10 is parallel to the axial line of the annular paper tube 1 and located outside the belt 2. One side of the cutting part 10 is provided with a cutting tooth 12. The cutting tooth on the cutting part can cut the belt.
[0028] Specifically, the elastic support structure 6 includes several connecting plates 13 arranged circumferentially along the circular connecting block 5. The outer surface of the connecting plate 13 abuts against the inner circumferential surface of the annular paper tube 1. The connecting plate 13 is connected to the circumferential surface of the circular connecting block 5 through an elastic connecting structure. The elastic connecting structure includes a connecting groove 14 provided on the circumferential surface of the circular connecting plate 13. A third connecting rod 15, inserted into the connecting groove 14, is fixedly connected to the inner surface of the connecting plate 13. An elastic element connecting the third connecting rod 15 is also provided in the connecting groove 14. The elastic element can drive the third connecting rod to move outward from the connecting groove, thereby enabling the outer surface of the connecting plate to abut against the inner circumferential surface of the annular paper tube. The elastic force of the elastic element and the friction between the connecting plate and the annular paper tube can fix the cutting part mounting plate on the annular paper tube. The connecting plate, which can move towards or away from the circular connecting block, allows the cutting part mounting plate to adapt to paper tubes of various sizes.
[0029] Specifically, the elastic element is a spring 16. One end of the spring 16 is fixed to the inner wall of the connecting groove 14, and the other end is fixed to the third connecting rod 15. The cross-section of the connecting plate 13 is arc-shaped.
[0030] Specifically, there are four connecting plates 13.
[0031] Specifically, the outer ends of the connecting part 11 and the second connecting rod 8 are detachably fixed by bolts, which can be easily disassembled, and the connecting plate and bolts are rotatably connected.
[0032] Preferably, combined with Figure 2 As shown, the belt body 2 is composed of a biodegradable plastic layer 17 and an adhesive layer 18. Making the belt body from a biodegradable plastic layer can greatly accelerate the degradation rate of the belt body, making it more environmentally friendly.
[0033] Specifically, the biodegradable plastic layer 17 is made of polybutylene succinate.
[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0035] Although the annular paper tube 1, the belt 2, the belt cutting piece 3, the cutting piece mounting plate 4, the circular connecting block 5, the elastic support structure 6, the first connecting rod 7, the second connecting rod 8, the threaded sleeve 9, the cutting part 10, the connecting part 11, the cutting tooth 12, the connecting plate 13, the connecting groove 14, the third connecting rod 15, the spring 16, the degradable plastic layer 17, the adhesive layer 18 and the like are used more in the present application, the use of these terms is only for the convenience of describing and explaining the essence of the present application; it is against the spirit of the present application to interpret them as any kind of additional limitation.
