DETAILED DESCRIPTION

[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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] The utility model provides an indentation device for paper box production through improvement. The technical solution of the utility model is:

[0024] like Figure 1 and Figure 2 As shown, a creasing device for paper box production comprises a base 1, a mounting frame 2 is fixedly mounted on the top of the base 1, the mounting frame 2 is a rectangular structure with an opening at the bottom, a creasing plate 3 is movably mounted on the mounting frame 2, and the creasing plate 3 can be creasing on the paper box by moving downward, a driving motor 4 is fixedly mounted on the side wall of the mounting frame 2, a rotating shaft 5 is fixedly mounted on the output end of the driving motor 4, the rotating shaft 5 is a cylindrical structure, a rotating plate 6 is movably mounted on the side wall of the mounting frame 2, the rotating plate 6 is a circular plate, the rotating shaft 5 and the rotating plate 6 are fixedly connected, an extrusion rod 9 is arranged on the rotating plate 6, the driving motor 4 is started, the driving motor 4 drives the rotating plate 6 to rotate through the rotating shaft 5, the rotating plate 6 further drives the extrusion rod 9 to rotate, the extrusion rod 9 can be rotated to squeeze the creasing plate 3, so that the creasing plate 3 moves downward to creasing the paper box, so that the effect of consistent creasing each time is achieved, and an adjusting mechanism is arranged on the rotating plate 6;

[0025] The adjusting mechanism includes a movable groove 7, a movable rod 8, an adjusting groove 10 and an adjusting bolt 11. The movable groove 7 is a groove of a rectangular structure, which is opened inside the rotating plate 6. The movable rod 8 is a cylindrical structure, which is movably installed inside the movable groove 7. The adjusting groove 10 is a groove of a cylindrical structure, which is opened inside the extrusion rod 9. The extrusion rod 9 is movably sleeved on the movable rod 8 through the adjusting groove 10. The adjusting bolt 11 is a cylindrical structure with threads, which is movably installed on the extrusion rod 9, and one end of the adjusting bolt 11 is threadedly connected to the movable rod 8. By providing a movable mechanism, the downward movement of the indentation plate 3 can be adjusted. Distance, rotate the adjusting bolt 11, the adjusting bolt 11 is threadedly connected to the movable rod 8, after the adjusting bolt 11 and the movable rod 8 are locked, the position of the extrusion rod 9 on the rotating plate 6 will be fixed, rotate the adjusting bolt 11, loosen the adjusting bolt 11 and the movable rod 8, at this time the movable rod 8 can move inside the movable groove 7, and then adjust the position of the extrusion rod 9 on the rotating plate 6, when the extrusion rod 9 is farther away from the rotating shaft 5, the greater the distance the indentation plate 3 moves downward, and the deeper the indentation is, conversely, when the extrusion rod 9 is closer to the rotating shaft 5, the smaller the distance the indentation plate 3 moves downward, and the shallower the indentation is, thereby achieving the effect of arbitrarily adjusting the depth of the indentation.

[0026] The extrusion rod 9 is movably connected with a movable sleeve 12, which is a hollow cylindrical structure. Through the setting of the movable sleeve 12, when the extrusion rod 9 squeezes the indentation plate 3, the movable sleeve 12 will rotate on the extrusion rod 9 to reduce the friction between the extrusion rod 9 and the indentation plate 3.

[0027] like Figure 3 As shown, in one embodiment, two limit blocks 13 are fixedly installed on the mounting frame 2 at positions corresponding to the indentation plate 3. The limit blocks 13 are blocks of rectangular structure. A reset rod 14 is fixedly installed at the position corresponding to the limit blocks 13 on the top of the indentation plate 3. The reset rod 14 is a cylindrical rod. The reset rod 14 passes through the upper and lower walls of the limit blocks 13 upward. A reset spring 15 is sleeved on the reset rod 14. When the indentation plate 3 moves downward, the reset rod 14 will squeeze the reset spring 15. When the squeezing rod 9 leaves the top of the indentation plate 3, the reset spring 15 releases the elastic force to drive the indentation plate 3 to reset upward.

[0028] like Figure 1 and Figure 3As shown, in one embodiment, a mounting plate 16 is fixedly installed on the side wall of the indentation plate 3, and the mounting plate 16 is a plate of a rectangular structure. A positioning plate 17 is arranged below the mounting plate 16, and the positioning plate 17 is a plate of a rectangular structure. The position of the positioning plate 17 is lower than the bottom of the indentation plate 3, and two limit rods 18 are fixedly installed on the top of the positioning plate 17. The limit rods 18 are cylindrical rods, and the limit rods 18 penetrate the upper and lower walls of the mounting plate 16 upward. An extrusion spring 19 is sleeved on the limit rod 18. When the indentation plate 3 moves downward to indent the carton, since the position of the positioning plate 17 is lower than the bottom of the indentation plate 3, the positioning plate 17 will first contact the carton, and then the carton will be squeezed and positioned by the elastic force released by the extrusion spring 19, and then the indentation plate 3 can indent the carton, thereby avoiding the situation where the indentation is skewed due to the displacement of the carton during indentation.

[0029] like Figure 4 As shown, in one embodiment, a rubber pad 20 is embedded and installed at the bottom of the positioning plate 17. The rubber pad 20 is a rectangular structure. The rubber pad 20 can increase the friction between the rubber pad 20 and the paper box, so that the paper box is positioned more stably.

[0030] The specific working methods are:

[0031] When the driving motor 4 is started, the driving motor 4 drives the rotating plate 6 to rotate through the rotating shaft 5, and the rotating plate 6 further drives the squeezing rod 9 to rotate. The squeezing rod 9 rotates to squeeze the indentation plate 3, so that the indentation plate 3 moves downward to indent the paper box, achieving the effect of consistent indentation each time. At the same time, by providing an adjusting mechanism, the downward moving distance of the indentation plate 3 can be adjusted, the adjusting bolt 11 is rotated, and the adjusting bolt 11 is threadedly connected with the movable rod 8. After the adjusting bolt 11 and the movable rod 8 are locked, the position of the squeezing rod 9 on the rotating plate 6 will be fixed, the adjusting bolt 11 is rotated, and the adjusting bolt 11 and the movable rod 8 are loosened. At this time, the movable rod 8 can be moved inside the movable groove 7, thereby adjusting the position of the squeezing rod 9 on the rotating plate 6. When the squeezing rod 9 is farther away from the rotating shaft 5, the downward moving distance of the indentation plate 3 is greater, and the indentation is deeper. On the contrary, when the squeezing rod 9 is closer to the rotating shaft 5, the downward moving distance of the indentation plate 3 is smaller, and the indentation is shallower, thereby achieving the effect of freely adjusting the indentation depth.

[0032] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
