Description

Technical Field

[0001] This application relates to the technical field of cardboard processing, and in particular to a cardboard processing slotting device. Background Art

[0002] After the cardboard is produced, it usually needs to be cut and scored so that it can be folded into a box for use as a package. The existing cardboard slotting and scoring device uses a belt to convey the cardboard. The cardboard passes under the pressure roller and the cutting roller. It is pressed by the convex edges on the pressure roller, and the cutter on the cutting roller performs corresponding cutting to make a preset shape. After removing the waste, according to the scoring and slotting positions, folding and splicing can be carried out to complete the production of the packaging box.

[0003] During the operation of the cutting roller, its cutter often contacts the conveyor belt below. Over time, the cutter will become dull or the teeth will break, resulting in incomplete cutting or inaccurate cutting. There will still be some positions connected in the cut cardboard. If the subsequent processing is not good, it will directly damage the cardboard facade and cause the cardboard to be scrapped; after the cutting roller has problems, it usually needs to be shut down for maintenance. The existing cutting roller is removed, and the damaged cutting roller is polished by itself or sent back to the original factory for maintenance. Since most of the existing cutting rollers are of an integral structure, their maintenance cycle is long, which affects the production progress. In addition, the fixed structure can adapt to a small number of cutting types and can only be carried out by replacing different types of cutting rollers, increasing the overall use cost. Therefore, to solve the above problems, this application provides a cardboard processing slotting device. Utility Model Content

Detailed implementation manners

[0022] The following further describes the present application in conjunction with the attached Figure 1 - Figure 5 for a more detailed description.

[0023] Embodiment 1:

[0024] A cardboard processing and grooving device, referring to Figure 1 - Figure 5 , includes a working platform 1 and a cutting roller installed above the working platform 1. A driving module 5 for driving the cutting roller is arranged below the working platform 1. An annular groove 21 is circumferentially formed on the cutting roller, and a sliding groove 22 is axially formed. The sliding groove 22 penetrates through the annular groove 21 and extends to both ends of the cutting roller;

[0025] A cutting module 3 that can be disassembled through the sliding groove 22 is slidably embedded inside the annular groove 21. A blade 31 is welded on the cutting module 3. The position of the cutting module 3 in the annular groove 21 is fixed by a locking assembly 4. A plurality of annular grooves 21 are formed and evenly distributed on the outer side of the cutting roller 2. A plurality of sliding grooves 22 are formed, and each of the plurality of sliding grooves 22 penetrates through the annular groove 21 on the cutting roller 2. The number of the annular grooves 21 and the sliding grooves 22 can be customized according to requirements. Usually, the number of the sliding grooves 22 is opened according to the number of the cutting modules 3 to ensure that when each group of cutting modules 3 is removed, it does not affect the positions of the surrounding cutting modules 3, thereby reducing the operation workload.

[0026] The cutting module 3 belongs to a mold part, which has various types of structures. Its size and the position where the blade 31 is welded can be customized according to production requirements. Since the cutting module 3 has a small size and low mold opening difficulty, its cost is much lower than that of the integral cutting roller 2 component; one or more cutting modules 3 are provided, and the plurality of cutting modules 3 are combined with each other on the cutting roller 2 according to actual needs, so as to splice various types of structures such as lines, rectangular grooves, and arc grooves to meet the requirements of different packaging boxes.

[0027] The longitudinal sections of the annular groove 21 and the slide groove 22 are both T-shaped structures, and their smaller openings face the outside of the cutting roller 2; the locking assembly 4 includes a slider 41 and a threaded rod 42 that are slidably embedded in the inner side of the slide groove 22 or the annular groove 21, the threaded rod 42 is vertically welded to the upper end surface of the slider 41, and the threaded rod 42 extends to the outside of the cutting roller. A through hole that cooperates with the threaded rod 42 is opened on the cutting module 3, and the end of the threaded rod 42 fixes the position of the cutting module 3 and the cutting roller 2 through a nut sleeve 44. A gasket 43 is arranged between the nut sleeve 44 and the cutting module 3, and the gasket 43 is used to improve the fixing stability. The diameter of the circle where the end edge of the threaded rod 42 is located is smaller than the diameter of the circle where the effective cutting section of the cutter is located, so as to avoid the threaded rod 42 from causing adverse effects on the normal cutting of the device during operation and damaging the cardboard structure.

[0028] When the nut rotates clockwise, it pulls the threaded rod 42 and the gasket 43 to move toward the outside of the cutting roller 2, increasing the friction between the gasket 43 and the inner wall of the slide groove 22 / annular groove 21, and increasing the friction between the cutting module 3 and the cutting roller 2, thereby completing the position fixation of the cutting module 3 on the cutting roller 2 and ensuring the stability of subsequent operation.

[0029] The working platform 1 is welded with columns 7 on both sides, and the two ends of the cutting roller 2 are welded with rotating shafts. The two rotating shafts are respectively placed on the top of the columns 7 through bearings, and the top of the columns 7 is threadedly connected to the fixing member 71 to fix the position of the cutting roller 2. The driving module 5 includes a reducer 52 installed below the working platform 1, and a motor 51 matched with the reducer 52. The reducer 52 is connected to the rotating shaft at one end of the cutting roller 2 through the transmission member 6. The transmission member 6 can be a chain, sprocket structure, synchronous belt, gear structure or belt, pulley structure to ensure the transmission effect of the driving module 5 on the cutting roller 2. A plug-in coupling 8 is arranged between the transmission member 6 and the rotating shaft of the cutting roller 2. The coupling 8 includes a component 1 81 and a component 2 82. A bolt-fixed structure can also be used between the component 1 81 and the component 2 82, but a plug-in structure is preferably used to facilitate the separation operation between the cutting roller 2 and the transmission member 6, thereby facilitating the removal and installation of the cutting roller 2, and further facilitating subsequent maintenance.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
