Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a high-efficiency and energy-saving packaging box creasing machine. Background Art

[0002] In the production process of packaging boxes, the creasing process occupies a vital position. As the name suggests, creasing is to apply pressure on the cardboard material of the packaging box through a specific mechanical device, so as to form a clear and precise creasing line at a specific position. This creasing line not only serves to indicate the folding position, but also enables the packaging box to be accurately and quickly folded according to the predetermined shape in the subsequent folding and forming process, greatly improving production efficiency;

[0003] Some packaging boxes require double-sided creasing, and existing creasing machines can usually only perform single-sided creasing. After one side of the creasing is completed, the worker needs to turn the packaging box over to the other side for another creasing operation, which is not only time-consuming and labor-intensive, but also reduces production efficiency. In addition, for double-sided creasing, the creasing machine needs to work for a long time, thereby increasing energy consumption and production costs. Therefore, an efficient and energy-saving packaging box creasing machine is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown in FIG. 4 , the embodiment of the utility model provides an energy-efficient packaging box creasing machine, including a creasing assembly 1, the creasing assembly 1 including a support frame 11, a through slot 12, a slider 13, a through hole 14, an upper shaft 15, an upper pressing roller 16, an upper mounting plate 17, a lower shaft 18, a lower pressing roller 19, a lower mounting plate 20 and a synchronous motor 21;

[0026] Through grooves 12 are provided on the upper parts of both sides of the support frame 11, and sliders 13 are slidably connected to the inner walls of the two through grooves 12. Through holes 14 are provided at the centers of the adjacent sides of the two sliders 13, and the inner wall rotation shafts of the two through holes 14 are connected to the upper shaft 15. The middle part of the outer wall of the upper shaft 15 is fixedly connected to the upper pressure roller 16, and one side of the two sliders 13 away from the upper pressure roller 16 is fixedly connected to the upper mounting plate 17, and one side of the upper shaft 15 passes through the center of one side of the upper mounting plate 17, and a lower shaft 18 passes through the lower part of one side of the support frame 11, and a lower pressure roller 19 is fixedly connected to the middle part of the outer wall of the lower shaft 18, and the lower part of the side of the support frame 11 close to the upper mounting plate 17 is fixedly connected to the lower mounting plate 17. Plate 20, one side of the lower shaft 18 passes through the center of one side of the lower mounting plate 20, and the upper mounting plate 17 and the lower mounting plate 20 are fixedly connected to the side away from the support frame 11 with a synchronous motor 21, and the upper shaft 15 and the lower shaft 18 are respectively fixedly connected to the output ends of the two synchronous motors 21. The slider 13 slides inside the through groove 12 to limit the slider 13, and the two synchronous motors 21 rotate synchronously towards each other, thereby driving the upper shaft 15 and the lower shaft 18 to rotate synchronously towards each other, and then driving the upper pressure roller 16 and the lower pressure roller 19 to rotate synchronously towards each other. By adopting the high-efficiency and energy-saving synchronous motor 21, it has higher energy efficiency ratio and lower energy consumption.

[0027] In one embodiment, specifically: a slide post 22 is fixedly connected at the center of the upper surface of the slider 13, a slide hole 23 is opened at the center of the inner top wall of the through groove 12, and the outer wall of the slide post 22 is slidably connected to the inner wall of the slide hole 23. The slide post 22 on the slider 13 slides inside the slide hole 23, thereby limiting the slide post 22 and further limiting the slider 13.

[0028] In one embodiment, specifically: a spring 24 is sleeved on the lower portion of the outer wall of the slide column 22, the top of the spring 24 is fitted and connected to the inner top wall of the through groove 12 near the outer side of the slide hole 23, and the bottom of the spring 24 is fitted and connected to the upper surface of the slider 13 near the outer side of the slide column 22. The elasticity of the spring 24 facilitates indentation of packaging boxes of different thicknesses. When indenting a thicker packaging box, the packaging box supports the upper pressure roller 16 to move upward, thereby driving the upper shaft 15 and the slider 13 to move upward, and then compressing the spring 24. When indenting a thinner packaging box, the thrust of the spring 24 is used to return to the original position, thereby pushing the slider 13 downward, thereby driving the upper pressure roller 16 on the upper shaft 15 downward.

[0029] In one embodiment, specifically: the middle parts of the front surface and the rear surface of the slider 13 are fixedly connected to the limiting blocks 25, the middle parts of the inner front wall and the inner rear wall of the through groove 12 are provided with limiting grooves 26, the outer wall of the limiting block 25 is slidably connected to the inner wall of the limiting groove 26, and the limiting block 25 on the slider 13 slides inside the limiting groove 26, thereby limiting the limiting block 25 and further limiting the slider 13.

[0030] In one embodiment, specifically: a belt conveyor 27 is fixedly connected to the upper portion of the front surface of the support frame 11, and a servo motor 28 is installed on the front portion of one side of the belt conveyor 27. The belt conveyor 27 is driven by the servo motor 28 to facilitate the conveyance of the packaging box between the upper pressing roller 16 and the lower pressing roller 19. The upper pressing roller 16 and the lower pressing roller 19 rotate synchronously, thereby driving the packaging box to continue to move while double-sided indentation is performed on the packaging box.

[0031] In one embodiment, specifically: the outer side walls of the upper pressing roller 16 and the lower pressing roller 19 are both provided with an indentation protrusion 29, and the upper pressing roller 16 and the lower pressing roller 19 are both provided with an indentation protrusion 29, so that double-sided indentation of the packaging box is facilitated.

[0032] In one embodiment, specifically: side panels 30 are fixedly connected to both sides of the rear surface of the support frame 11, an inclined blanking plate 31 is fixedly connected to the front of the adjacent side of the two side panels 30, a trolley 32 is slidably connected to the rear of the adjacent side of the two side panels 30, and the top of the front surface of the trolley 32 is fitted and connected to the rear surface of the inclined blanking plate 31. The inclined setting of the inclined blanking plate 31 facilitates the packaging box with double-sided indentation to slide into the compartment of the trolley 32.

[0033] In one embodiment, specifically: push handles 33 are welded on the upper parts of both sides of the rear surface of the cart 32. After the compartment of the cart 32 is full, the cart 32 can be used to push the packaging box with double-sided embossing to the next process.

[0034] When the utility model is working: firstly, the belt conveyor 27 and the synchronous motor 21 are started, and the belt conveyor 27 conveys the packaging box to be indented between the upper pressing roller 16 and the lower pressing roller 19. At this time, the two synchronous motors 21 rotate synchronously towards each other, driving the upper shaft 15 and the lower shaft 18 to rotate synchronously towards each other, thereby making the upper pressing roller 16 and the lower pressing roller 19 rotate synchronously towards each other. When the packaging box enters between the upper pressing roller 16 and the lower pressing roller 19, it is subjected to the pressure generated by the rotation of the two rollers towards each other, thereby forming an indentation line at a specific position of the packaging box. Since the outer side walls of the upper pressing roller 16 and the lower pressing roller 19 are provided with indentation protrusions 29, these protrusions can ensure that clear and accurate indentation lines are formed on the packaging box. At the same time, when indenting a thicker packaging box , the packaging box will support the upper pressing roller 16 to move upward, driving the upper shaft 15 and the slider 13 to move upward, thereby compressing the spring 24. When indenting a thinner packaging box, the spring 24 will use its reset thrust to push the slider 13 downward, thereby driving the upper shaft 15 and the upper pressing roller 16 to move downward, ensuring the accuracy and consistency of the indentation. The elasticity of the spring 24 can be used to adapt to packaging boxes of different thicknesses. After the indentation is completed, the packaging box slides onto the inclined blanking plate 31. Due to the inclined setting of the inclined blanking plate 31, the packaging box will slide into the carriage of the cart 32 along its inclined surface. When the carriage of the cart 32 is full, the staff can push the cart 32 away by the push handle 33, and send the packaging box with double-sided indentation to the next process for further processing.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
