It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example
[0015] like Figure 1 , Figure 2 , Figure 3 As shown, a creasing device for folding cartons includes an operating table 1. Several conveyor rollers 2 are rotatably mounted on the operating table 1. A first synchronous gear 301 is fixedly mounted on one side of each conveyor roller 2. Each conveyor roller 2 has a first synchronous gear 301 on one side. A first synchronous belt 302 meshes with the outer sides of two adjacent first synchronous gears 301. A second synchronous gear 303 is fixedly mounted on one side of each first synchronous gear 301. A second synchronous belt 304 meshes with the outer sides of two adjacent second synchronous gears 303. A support plate 30 is rotatably mounted on the outer side of the second synchronous belt 304. 5. No second synchronous gear 303 is provided on the outer side of the first synchronous gear 301 at both ends. The support plate 305 is fixedly installed on one side of the operating table 1. A first servo motor 306 is fixedly installed on one side of the operating table 1. The output shaft of the first servo motor 306 is fixedly installed on the outer side of the first synchronous gear 301 at the outermost end. The output shaft of the first servo motor 306 drives the first synchronous gear 301 at the outermost end to rotate. The first synchronous gear 301, the first synchronous belt 302 and the second synchronous gear 303 and the second synchronous belt 304 are arranged in an alternating manner, which can make several conveying rollers 2 on the operating table 1 rotate in the same direction to convey the cardboard on the conveying rollers 2.
[0016] like Figure 1 , Figure 2 , Figure 5As shown, a fixed plate 4 is fixedly installed in the middle of the operating platform 1. A second servo motor 5 is fixedly installed on the lower side of the fixed plate 4. A turntable 6 is fixedly installed on the output shaft of the second servo motor 5. The upper side of the turntable 6 is on the same plane as the upper side of the operating platform 1, the conveying roller 2, and the fixed plate 4. A first mounting bracket 7 is fixedly installed on the upper side of the operating platform 1. A first electric telescopic rod 801 is fixedly installed in the middle of one side of the first mounting bracket 7. A connecting plate 802 is fixedly installed at the output end of the first electric telescopic rod 801. A rotating frame 803 is rotatably installed on the lower side of the connecting plate 802. The rotating frame 803 is composed of two plates whose inner and outer ends are fixedly connected by several rods. A clamping plate 804 is installed on the lower side of the rotating frame 803. A round rod 805 is fixedly installed in the middle of the upper side of the clamping plate 804. The round rod 805 slides through the bottom of the rotating frame 803. Several springs 806 are fixedly installed on the outer upper side of the clamping plate 804. The upper side of the spring 806 is fixedly set to the lower side of the rotating frame 803. After the cardboard is creasing at one angle, it needs to be rotated to creasing at another angle. The first electric telescopic rod 801 is started. The output end of the first electric telescopic rod 801 drives the connecting plate 802 to move the rotating frame 803 and the clamping plate 804 downward until the lower side of the clamping plate 804 is in contact with the upper side of the cardboard. The spring 806 is set to buffer the downward clamping of the clamping plate 804 to prevent the cardboard from deforming. Then the second servo motor 5 is started. The output shaft of the second servo motor 5 drives the turntable 6 to rotate, so that the clamping plate 804 and the turntable 6 clamp the cardboard and rotate. After the angle of the cardboard is rotated, the first electric telescopic rod 801 is started. The output end of the first electric telescopic rod 801 drives the connecting plate 802 to move the rotating frame 803 and the clamping plate 804 upward. In cooperation with the conveyor roller 2, the cardboard can be creasing at a different angle for a second time.
[0017] like Figure 3 , Figure 4 , Figure 6As shown, the upper sides of the first mounting bracket 7 are provided with recesses 9 offset from each other. A third servo motor 10 is fixedly mounted on both sides of the first mounting bracket 7. A threaded rod 11 is fixedly mounted on the output shaft of the third servo motor 10. The threaded rod 11 is rotatably mounted within the recesses 9. The outer side of the threaded rod 11 is threaded to a U-shaped frame 12. U-shaped frames 12 are provided within the recesses 9 on both sides. A second electric telescopic rod 13 is fixedly mounted inside the U-shaped frame 12. The output end of the second electric telescopic rod 13 is connected to the upper side of the second mounting bracket 14. A fourth servo motor 15 is fixedly mounted on one side of the second mounting frame 14. The output shaft of the fourth servo motor 15 is fixedly mounted to the coarse pressure roller 16. The coarse pressure roller 16 is rotatably mounted inside one side of the second mounting frame 14, and a fine pressure roller 17 is rotatably mounted inside the other side of the second mounting frame 14. According to the direction of paperboard movement, the paperboard first passes through the coarse pressure roller 16 for indentation, and then passes through the fine pressure roller 17 for indentation. A heating block 18 is fixedly mounted on one side of the second mounting frame 14, and a heating element is fixedly mounted inside the bottom side of the heating block 18. The heating temperature of the resistance wire 19 is controlled between 75℃ and 85℃. A limit rod 20 is fixedly installed on the upper side of the second mounting bracket 14, and a limit fixing block 21 is fixedly installed on the bottom side of one side of the C-shaped frame 12. The limit rod 20 is slidably installed inside the limit fixing block 21. When creasing the cardboard, the third servo motor 10 is started first to move the C-shaped frames 12 on both sides to the corresponding creasing positions on the cardboard. Then, the second electric telescopic rod 13 is started. The output end of the second electric telescopic rod 13 carries the second mounting bracket 14. 4. Move downwards. When the second mounting bracket 14 moves, it is limited by the limit rod 20 until the bottom surface of the coarse pressure roller 16, the fine pressure roller 17 and the heating block 18 are in contact with the upper side of the cardboard. Then, the fourth servo motor 15 is started. The output shaft of the fourth servo motor 15 drives the coarse pressure roller 16 to rotate. The cardboard is first heated by the heating resistance wire 19, then coarsely pressed by the coarse pressure roller 16, and finally finely pressed by the fine pressure roller 17. The coarse pressure roller 16 is driven to rotate by the fourth servo motor 15, so that the cardboard can be creasing while moving.
[0018] It should be noted that, in use, this creasing device for folding cartons involves placing the cardboard on one end of the conveyor roller 2, starting the first servo motor 306, which rotates several conveyor rollers 2 on the operating table 1 to convey the cardboard. When the cardboard reaches the fixed plate 4, the third servo motor 10 is started, driving the threaded rod 11 to rotate, causing the mortise frame 12, along with the coarse pressure roller 16 and the fine pressure roller 17, to move to the position where the cardboard needs creasing. Then, the second electric telescopic rod 13 is started, and its output end drives the second mounting frame 14 to move downwards, causing the coarse pressure roller 16 and the fine pressure roller 17 to contact the bottom surface of the heating block 18. Finally, the fourth servo motor 15 is started. 15 drives the coarse pressure roller 16 to rotate, creasing the cardboard. After creasing the cardboard at one angle, the conveyor roller 2 moves the cardboard backward. Then, the first electric telescopic rod 801 is activated, moving the clamping plate 804 downward. The clamping plate 804 and the turntable 6 clamp the cardboard. The second servo motor 5 is activated, and the output shaft of the second servo motor 5 drives the turntable 6 to rotate, adjusting the angle of the cardboard. After the cardboard angle is adjusted, the first electric telescopic rod 801 is activated, moving the clamping plate 804 upward. The third servo motor 10, the second electric telescopic rod 13, and the fourth servo motor 15 are activated again to creasing the cardboard at another angle.
[0019] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
