Technical Field

[0001] The utility model belongs to the technical field of carton processing, and particularly relates to a secondary creasing and folding mechanism for corrugated cartons. Background Technique

[0002] As a commonly used packaging and storage device, corrugated cartons are often used in container transportation. Compared with traditional wooden boxes and iron boxes, they have the advantages of low cost and environmental protection. Therefore, corrugated cartons have gradually become the main device for packaging and transportation. The most important process in the processing of corrugated cartons is to perform secondary creasing and folding on them, so that they can be transformed from the cardboard state to the carton structure state. Therefore, the quality of this process has a great impact on the quality of corrugated cartons.

[0023] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0024] The embodiment of the present utility model provides a secondary creasing and folding mechanism for corrugated cardboard boxes, as Figures 1-4As shown in the figure, it includes a base 1. At the central position on the top of the base 1, a fixed platform 2 is fixedly connected by bolts. At one side position of the fixed platform 2, a first turntable 3 is provided, and at the other side position of the fixed platform 2, a second turntable 4 is provided. Between the first turntable 3 and the second turntable 4 and the fixed platform 2, hinges 5 are fixedly connected by screws. There are four hinges 5 in total, and every two of the four hinges 5 are symmetrically arranged in groups between the first turntable 3 and the second turntable 4 and the fixed platform 2 respectively. On the top of the fixed platform 2, two side baffles 6 are symmetrically fixedly connected by bolts. The side baffles 6 are perpendicular to the fixed platform 2. On the top of the second turntable 4, a limiting plate 7 is fixedly connected by bolts. The limiting plate 7 is perpendicular to the second turntable 4. At one side position of the top of the base 1 close to the fixed platform 2, a fixing plate 8 is fixedly connected by bolts. There are four fixing plates 8 in total, and the four are symmetrically arranged on the top of the base 1. On the outer wall of one side of the fixing plate 8, a rotary cylinder 9 is fixedly connected by bolts. The rotary cylinder 9 is fixedly connected with a disc 10 through the output end on one side thereof. Connecting columns 11 are welded between the first turntable 3 and the second turntable 4 and the disc 10. At one side position of the top of the base 1 close to the fixing plate 8, a top column 12 is fixedly connected by bolts. At one side position of the top of the fixed platform 2 close to the side baffle 6, a fixing rod 13 is welded. The top of the fixing rod 13 is welded with a top plate 14. On the top of the top plate 14, a hydraulic cylinder 15 is fixedly connected by bolts. The hydraulic cylinder 15 is fixedly connected with a pressing platform 16 through the output end on one side thereof.

[0025] It should be noted that since the existing secondary creasing and folding mechanism of corrugated cardboard boxes requires manual lifting of the pull rod to fold the cardboard during use, the folding efficiency is low and it is also labor-consuming. In this embodiment, by rotating the first turntable 3 and the second turntable 4 upward by 90 degrees, a part of the corrugated cardboard on the first turntable 3 and the second turntable 4 can be folded, and then the cardboard can be folded into the shape of a corrugated cardboard box, realizing secondary creasing and folding, improving the processing efficiency of the corrugated cardboard box, realizing automatic folding, without the need for manual strenuous folding, saving time and effort. Through the mutual cooperation of the side baffle 6, the limiting plate 7 and the pressing platform 16, the positioning and fixing of the corrugated cardboard before and after processing are realized, avoiding deviation of the corrugated cardboard during folding and ensuring the forming quality of the corrugated cardboard box.

[0026] Specifically, in this embodiment, the solution mainly includes a fixed table 2, a first turntable 3, a second turntable 4, and a pressing table 16. When in use, the corrugated cardboard box is horizontally inserted between two side baffles 6, and one end of the corrugated cardboard box contacts the limiting plate 7. The corrugated cardboard box is placed on the tops of the fixed table 2, the first turntable 3, and the second turntable 4. When performing secondary creasing and folding, the hydraulic cylinder 15 drives the pressing table 16 to move downward through the output end on one side. During the downward movement of the pressing table 16, the corrugated cardboard box is squeezed, realizing the fixation of the position of the corrugated cardboard box. At this time, the rotary cylinder 9 drives the disc 10 to rotate 90 degrees through the output end on one side. The connecting column 11 on the disc 10 performs circular motion. Since the first turntable 3 and the second turntable 4 are hinged to the fixed table 2 through the hinge 5, the first turntable 3 and the second turntable 4 rotate upward by 90 degrees, and a part of the corrugated cardboard box on the first turntable 3 and the second turntable 4 is folded, thereby folding the cardboard into the shape of a corrugated cardboard box, realizing secondary creasing and folding, and improving the processing efficiency of the corrugated cardboard box.

[0027] In a further preferred embodiment of the present invention, as Figure 1 and Figure 3 shown, the output end of the rotary cylinder 9, the center of the disc 10, and the axis of the hinge 5 are on the same horizontal axis, and the connecting column 11 is located at an eccentric position of the disc 10.

[0028] In this embodiment, through the same axis setting, the first turntable 3 and the second turntable 4 rotate along the same horizontal axis during rotation, so that the first turntable 3 and the second turntable 4 can rotate to be perpendicular to the fixed table 2, realizing the folding of the corrugated cardboard box.

[0029] In a further preferred embodiment of the present invention, as Figure 1 shown, the bottoms of the first turntable 3 and the second turntable 4 both contact the top of the top column 12.

[0030] In this embodiment, the first turntable 3 and the second turntable 4 can be supported by the top column 12, so that the first turntable 3 and the second turntable 4 are in a horizontal state, and then horizontally support the corrugated cardboard box.

[0031] In a further preferred embodiment of the present invention, as Figure 1 shown, the pressing table 16 and the side baffle 6 are offset in the vertical direction.

[0032] In this embodiment, it can effectively avoid the movement interference caused by the contact between the pressing table 16 and the side baffle 6, and then enable the pressing table 16 to effectively press and limit the corrugated cardboard box.
