DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6The utility model provides a technical solution: a paper splicer with a protective structure, comprising a paper splicer body 1, an electric telescopic rod 2 fixedly installed inside the paper splicer body 1, a mounting plate 3 fixedly connected to the output end of the electric telescopic rod 2 and a blade 4 fixedly installed at the bottom of the mounting plate 3, a protective cover 5 is movably sleeved on the outer surface of the mounting plate 3, a slider 6 is fixedly connected to the outer surface of the mounting plate 3, a sliding rod 7 is fixedly connected inside the protective cover 5, a sliding groove matching the sliding rod 7 is opened at the inner center of the slider 6, the outer surface of the sliding rod 7 is inserted into the sliding groove, a first spring 8 is movably sleeved on the outer surface of the sliding rod 7, a positioning plate 9 is slidably connected inside the protective cover 5, a convex plate 91 is fixedly connected to the outer surface of the positioning plate 9, the outer surface of the convex plate 91 is slidably connected to the inside of the protective cover 5, a silicone plate 10 is fixedly connected to the surface of the positioning plate 9, and the surface of the positioning plate 9 away from the silicone plate 10 is The body is connected with a protrusion 11, and the protrusion 11 extends away from the surface of the silicone plate 10 to the outside of the inner wall of the protective cover 5. A positioning groove 12 is provided inside the positioning plate 9, and the positioning groove 12 is trapezoidal. The internal sliding connection of the protective cover 5 is a limit ring 13, and the limit ring 13 is square. The interior of the limit ring 13 is fixedly connected with a sliding column 14, and the internal top of the sliding column 14 is rotatably connected with a roller 15, and the surface of the roller 15 is against the inner wall of the positioning groove 12. The bottom of the sliding column 14 is threadedly connected with a threaded rod 16, and the bottom of the threaded rod 16 extends to the bottom of the protective cover 5. By setting a slidable protective cover 5 and a protrusion 11 that can limit the slider 6, when the electric telescopic rod 2 drives the blade 4 to slide downward through the mounting plate 3, the blade 4 can only cut the paper at a set height, ensuring the accuracy and consistency of the cutting, while also avoiding the flying of paper scraps after cutting, thereby enhancing practicality;

[0024] A light touch switch 17 electrically connected to the electric telescopic rod 2 is fixedly installed at the inner bottom end of the protective cover 5, and a bottom plate 18 is slidably connected to the inner bottom end of the protective cover 5. The bottom of the bottom plate 18 is flush with the bottom of the protective cover 5. The bottom plate 18 is a rubber plate. A slip ring 19 is fixedly sleeved on the outer surface of the bottom plate 18. Both the bottom plate 18 and the slip ring 19 are annular. A second spring 20 is equidistantly and movably installed on the surface of the slip ring 19. Under normal circumstances, the elasticity of the second spring 20 makes the bottom of the slip ring 19 abut against the inside of the protective cover 5. By arranging the bottom plate 18 and the light touch switch 17, when there are debris at the bottom of the protective cover 5 or the operator mistakenly operates the blade 4 during maintenance work, the sliding of the bottom plate 18 can abut against the input end of the light touch switch 17, so that the electric telescopic rod 2 can be in a power-off state, avoiding the problem of safety hazards caused by the downward movement of the blade 4, thereby improving the safety of the blade 4 and the staff.

[0025] When working, the paper moves to the bottom of the blade 4, and the electric telescopic rod 2 is started, and the electric telescopic rod 2 drives the blade 4 to slide downward through the mounting plate 3. At this time, the mounting plate 3 drives the slider 6 to slide downward on the outer surface of the sliding rod 7. Through the elasticity of the first spring 8, the protective cover 5 will also slide downward. When the bottom of the threaded rod 16 abuts against the surface of the paper splicer body 1, the positioning plate 9 will not slide due to the elasticity of the silicone plate 10. When the protective cover 5 continues to slide downward, the pressure at the bottom of the threaded rod 16 is large enough, and the threaded rod 16 will drive the roller 15 to slide upward through the sliding column 14, and the friction between the roller 15 and the inner wall of the positioning groove 12 drives the positioning The plate 9 slides in the direction away from the sliding rod 7, and the protrusion 11 retracts into the protective cover 5. At this time, the slider 6 can slide downward, and the blade 4 can cut the paper. If there is debris at the bottom of the silicone plate 10 or the operator's hand is underneath, the protective cover 5 slides downward, and the bottom plate 18 drives the bottom plate 18 to slide upward due to the pressure at the bottom, and triggers the touch switch 17 to cut off the power to the electric telescopic rod 2. When there is a foreign object at the bottom of the bottom plate 18, the bottom of the threaded rod 16 will not be subjected to great pressure, the protrusion 11 is not completely retracted, and the mounting plate 3 drives the blade 4 to slide downward. The distance is limited, thereby greatly improving the protection performance and reducing safety hazards.
