DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-3 In this embodiment, a carton punching machine that is easy to replace includes a processing table 1, a support frame 2 is arranged on the top of the processing table 1, a punching device 3 is arranged at the bottom of the support frame 2, and a replacement structure 4 is arranged at the bottom of the punching device 3.

[0022] The punching device 3 includes an electric telescopic rod 301, a motor 302, a fixed plate 303, a connecting ring 304, a drill bit 305, a fixed cover 306 and an insertion rod 307. The electric telescopic rod 301 is fixedly installed inside the support frame 2, the motor 302 is fixedly installed at the bottom of the electric telescopic rod 301, the fixed plate 303 is fixedly installed at the bottom of the motor 302, the connecting ring 304 is movably installed inside the fixed plate 303, the drill bit 305 is fixedly installed at the bottom of the connecting ring 304, the fixed cover 306 is movably installed outside the fixed plate 303, and the insertion rod 307 is fixedly installed inside the fixed cover 306.

[0023] The replacement structure 4 includes a fixed block 401, a push rod 402, a threaded groove 403, a functional rod 404, a connecting plate 405 and a spring 406. The fixed block 401 is fixedly installed inside the fixed cover 306, the push rod 402 is movably installed inside the fixed block 401, the threaded groove 403 is provided outside the push rod 402, the functional rod 404 is movably installed inside the fixed block 401, the connecting plate 405 is fixedly installed outside the functional rod 404, and the spring 406 is fixedly installed outside the connecting plate 405.

[0024] exist Figure 2 In the embodiment, a movable groove is provided inside the fixing plate 303 , and the connecting ring 304 fits in the movable groove. The connecting ring 304 is then fixed by the insert rod 307 , so that the connecting ring 304 and the fixing plate 303 are fixed.

[0025] exist Figure 2 In the embodiment, the fixing plate 303 penetrates the fixing cover 306, and the fixing cover 306 prevents the connection ring 304 from being separated from the fixing plate 303, and then the fixing cover 306 is fixed according to the replacement structure 4.

[0026] exist Figure 2When the motor 302 drives the fixed plate 303 to rotate, the drill bit 305 is rotated at the same time to drill holes in the carton. The punching groove on the top of the processing table 1 facilitates the positioning of the carton and does not limit the depth of the drill bit 305 to descend.

[0027] To sum up, the carton punching machine which is easy to replace rotates the push rod 402 and moves the push rod 402 away from the functional rod 404. The rebound of the spring 406 outside the functional rod 404 will drive the functional rod 404 to retract into the fixed block 401. After the fixed cover 306 is separated from the fixed plate 303, the connecting ring 304 and the drill bit 305 are removed from the fixed cover 306, and the new connecting ring 304 and the drill bit 305 are installed inside the fixed cover 306, so that the drill bit 305 can be replaced conveniently.

[0028] In addition, the carton punching machine is easy to replace. The carton is on the processing table 1, and the electric telescopic rod 301 drives the drill bit 305 to approach the carton. The motor 302 drives the drill bit 305 to rotate the carton to complete the drilling of the carton. A punching groove is provided on the top of the processing table 1, which makes it easier to position the carton when punching. This solves the problem that the drill bit 305 of most punching machines is easily worn out due to multiple drillings when punching with the carton, affecting the efficiency of subsequent drilling. Usually, the replacement of the drill bit 305 is relatively complicated, in order to improve the efficiency of carton punching.
