Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a high-precision indentation device for carton processing. Background Technique

[0002] As described in the publicly disclosed patent "A flat-bed indentation and cutting machine for carton indentation" with the publication number CN208452417U, a carton is a three-dimensional shape. When producing a carton, it is generally indented to facilitate subsequent folding and packaging. When indenting it, a flat-bed indentation and cutting machine is generally used. Generally, a flat-bed indentation and cutting machine drives the cardboard to move and then performs indentation and cutting on it. During the movement of the cardboard, the cardboard will tilt, resulting in uneven indentation and cutting, making it unable to meet the technical requirements. In view of this, we propose a flat-bed indentation and cutting machine for carton indentation.

[0003] As described in the publicly disclosed patent "A flat-bed indentation and cutting machine for carton indentation" with the publication number CN207310628U, during the processing and manufacturing of cartons, indentation treatment is required. Some of these indentations are for folding needs, and some are for the products themselves. In the past, the carton indentation process was completed by workers using simple indentation tools or some semi-automatic indentation devices. These methods all have the problem of low work efficiency to varying degrees, and the indentation effect of some indentation tools is not good, the quality of the products is uneven, and it is difficult to carry out batch production.

[0004] To sum up, during the existing carton production process, it is necessary to indent the cardboard, but the existing indentation process has the problem of a high defective rate. Content of the Utility Model

Detailed Description of the Preferred Embodiment

[0026] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Please refer to Figure 1-7 , an embodiment provided by the present invention: a high-precision indentation device for carton processing, including a processing table 1, a first toothed plate 4, a first motor 7, a cardboard 19, a second motor 23, and a roller 31. An indentation groove 2 is opened in the middle of the upper end of the outer wall of the processing table 1, and fixing grooves 3 are opened on the left and right sides inside the processing table 1. The rear end of the outer wall of the processing table 1 is connected to a first toothed plate 4, and the left end of the outer wall of the first toothed plate 4 is engaged with a first gear 6. The rear end of the outer wall of the first gear 6 is provided with a first motor 7 fixed on the processing table 1. A rotating plate 11 is arranged in the fixing groove 3, and a cardboard 19 is placed on the upper ends of the outer walls of the two groups of rotating plates 11. The upper end of the outer wall of the first toothed plate 4 is fixedly connected to a fixing plate 20, and a second motor 23 is arranged on the right side of the fixing plate 20. A roller 31 that rolls back and forth is arranged at the lower end of the outer wall of the fixing plate 20;

[0028] Further, a limiting block 5 is fixedly connected to the front end of the outer wall of the first toothed plate 4, and the limiting block 5 is adapted to the rear end of the outer wall of the processing table 1. The limiting block 5 is used for limiting to prevent the roller 31 from pressing down too deeply and damaging the cardboard 19. The output end of the first motor 7 is fixedly connected to the first gear 6, and a second gear 8 rotatably arranged on the processing table 1 is engaged with the outer wall surface of the first gear 6. A third gear 9 rotatably arranged on the processing table 1 is engaged with the outer wall surface of the second gear 8. The front end of the outer wall of the third gear 9 is fixedly connected to a rotating rod 10, and the end of the outer wall of the rotating rod 10 is fixedly connected to the rear end of the outer wall of the rotating plate 11. Multiple groups of teeth are equidistantly arranged at the left and right ends of the outer wall of the first toothed plate 4. After the first motor 7 drives the first gear 6 to rotate, while the first toothed plate 4 moves vertically, the third gear 9 can drive the rotating rod 10 to rotate in the same direction as the first gear 6.

[0029] Further, a sleeve rod 12 is fixedly connected to the middle of the inside of the rotating plate 11, and a first card slot 13 is opened in the middle of the inner wall of the sleeve rod 12. A first spring 14 is arranged in the middle of the inner wall of the first card slot 13. A telescopic rod 15 is inserted into the middle of the inner wall of the first card slot 13, and the lower end of the first spring 14 is fixedly connected to the lower end of the telescopic rod 15. The upper end of the first spring 14 is limited within the opening of the first card slot 13 (as Figure 5As shown), a clamping plate 16 is fixedly connected to the upper end of the telescopic rod 15, and multiple groups of rollers 17 are equidistantly arranged on the lower side of the outer wall of the clamping plate 16. The outer wall surface of the rollers 17 is adapted to the outer wall surface of the cardboard 19. A pulling rod 18 is fixedly connected to the upper end of the outer wall of the clamping plate 16. This structure can rotate the rotating plate 11 at a certain angle through the rotating rod 10, and can be vertically moved by pulling the pulling rod 18. After moving to a certain position, the cardboard 19 placed in the middle can be stably clamped, and then the rotating plate 11 can be rotated to adapt to the cardboard 19 during subsequent use, as Figure 2 shown.

[0030] Furthermore, a limiting groove 21 is opened in the middle of the inner wall of the fixing plate 20, and a fixing block 22 is fixedly connected to the right end of the outer wall of the fixing plate 20. A second motor 23 is installed in the middle of the fixing block 22. The output end of the second motor 23 is connected to a fourth gear 24. A second toothed plate 25 is arranged at the lower end of the outer wall of the fixing plate 20. A limiting rod 26 adapted to the inner wall of the limiting groove 21 is fixedly connected to the upper end of the outer wall of the second toothed plate 25. The limiting rod 26 slides back and forth in the limiting groove 21 in a sliding fit. The right end of the outer wall of the second toothed plate 25 meshes with the outer wall surface of the fourth gear 24. This structure can be driven to rotate by the second motor 23, so that the fourth gear 24 drives the second toothed plate 25 to move back and forth.

[0031] Furthermore, a second clamping groove 27 is opened on the lower end surface of the second toothed plate 25, and a second spring 28 is arranged inside the second clamping groove 27. The lower end of the outer wall of the second spring 28 is fixedly connected to a connecting block 29, and a clamping plate 30 is fixedly connected to the end of the outer wall of the connecting block 29. Multiple groups of rollers 31 are equidistantly connected to the lower end of the outer wall of the clamping plate 30. This structure can generate partial buffering when the rollers 31 move vertically and contact the surface of the cardboard 19, avoiding damaging the surface of the cardboard 19 too quickly.

[0032] Furthermore, the outer wall corners of the rotating plate 11 and the clamping plate 16 are both set as rounded corners, and the outer wall surface of the pulling rod 18 is smooth and has no sharp edges. This structure can avoid damaging the cardboard 19 by the sharp edges between the structures when clamping the cardboard 19.

[0033] Working principle: When in use, multiple groups of cardboard 19 can be placed on the upper ends of the outer walls of the two rotating plates 11, and the telescopic rod 15 and the clamping plate 16 can be driven to move vertically by pulling the pulling rod 18. At this time, the clamping plate 16 and the rotating plate 11 are in an open state, and the cardboard 19 can be placed. Then, when the telescopic rod 15 moves, it will squeeze the first spring 14 in the first clamping groove 13. After the cardboard 19 is placed, the clamping plate 16 can be released, so that the first spring 14 rebounds after being squeezed, thereby driving the clamping plate 16 to stably clamp the placed cardboard 19;

[0034] At this time, the first motor 7 can be remotely started to drive the first gear 6 to rotate. At the same time, the meshing second gear 8 and third gear 9 are rotated for use. Thus, when the third gear 9 rotates, the rotating rod 10 is driven to rotate, so as to drive the rotating plate 11 on the inner wall of the fixed groove 3 to rotate. And when the first gear 6 rotates, the first toothed plate 4 is also driven to move in the vertical position, so that the fixed plate 20 drives the roller 31 to move vertically. And the roller 31 is directly attached to the upper end of the outer wall of the cardboard 19. And through the connection between the clamping plate 30 and the connecting block 29, and through the extrusion and rebound of the second spring 28, when the roller 31 contacts the cardboard 19, partial buffering can be generated to avoid damage. And when the roller 31 contacts the cardboard 19, the rotating plate 11 rotates to a certain angle (as Figure 2 shown). At this time, the roller 31 presses the middle of the cardboard 19 inside the middle of the pressing groove 2. At this time, the second motor 23 in the fixed block 22 can be started to drive the fourth gear 24 at its output end, and the fourth gear 24 is driven to rotate so that the second toothed plate 25 meshes with its outer wall surface. And the second toothed plate 25 moves back and forth at the lower end of the fixed plate 20 through the limiting rod 26, so that multiple rollers 31 roll on the middle of the outer wall of the cardboard 19 to roll out obvious creases. Thus, when folding the cardboard 19, it is simple and easy, and the folding is symmetrical, which is convenient for subsequent processing and use.

[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
