Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box processing technology, and in particular to a corrugated cardboard box creasing device. Background Technology

[0002] Corrugated cardboard boxes are boxes made of corrugated paper, often used for packaging goods for convenient transportation. An existing device, CN 219214240 U, ​​describes a corrugated cardboard creasing device. This device uses a belt conveyor to transport the corrugated cardboard, and then an electric telescopic rod drives a sliding plate to slide downwards along a limiting groove. When the sliding plate contacts a lifting plate, it stops moving downwards, and the creasing knife presses down on the corrugated cardboard at an appropriate height, thus creasing it. However, the belt conveyor cannot accurately limit the position of the corrugated paper when transporting it to the creasing component, potentially causing the creasing position to deviate and affecting production quality. Utility Model Content

[0003] The purpose of this invention is to provide a corrugated cardboard box creasing device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A corrugated cardboard box creasing device includes a support mechanism, on which a creasing mechanism for applying pressure to corrugated paper is provided, and a limiting mechanism for adjusting and limiting the placement position of the corrugated paper is provided on the support mechanism. The limiting mechanism includes a longitudinal limiting component, on which a transverse limiting component for laterally limiting the corrugated paper is provided. The longitudinal limiting component includes a longitudinally arranged lead screw, on which a sliding seat is mounted, and a limiting frame is provided at the upper end of the sliding seat. The limiting frame has a through groove. The transverse limiting component includes left and right helical screws provided at the rear side of the limiting frame, and transverse limiting seats are arranged opposite to each other on the left and right helical screws. The transverse limiting seats pass through the through groove, and one end of the left and right helical screws is connected to a power source.

[0006] Further details: The support mechanism includes a worktable, a crossbeam at the upper end of the worktable, a cavity inside the worktable located behind the crossbeam, and a groove communicating with the cavity on the upper surface of the worktable.

[0007] Further configuration: The sliding seat is located inside the cavity of the worktable, and the front end of the lead screw passes through the worktable and is connected to a handwheel.

[0008] Further configuration: The lead screw is rotatably connected to the worktable, the lead screw is threadedly connected to the sliding seat, and the sliding seat is slidably connected to the worktable.

[0009] Further configuration: The left and right helical screws are rotatably connected to the limiting frame, the lateral limiting seat is threadedly connected to the left and right helical screws, and the lateral limiting seat is slidably connected to the through groove.

[0010] Further details: The lower end face of the limit frame and the lower end face of the transverse limit seat are flush with the upper end face of the worktable, and a scale is provided on the worktable on one side of the limit frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By setting the longitudinal and transverse limiting components of the limiting mechanism, the rotation of the lead screw pushes the limiting frame on the sliding seat to adjust the distance between it and the creasing knife. The rotation of the left and right spiral screws causes the transverse limiting seats on the left and right spiral screws to move relative to each other under the limitation of the through groove. The distance between the transverse limiting seats is adjusted to match the width of the corrugated paper, which facilitates the limiting and fixing of the corrugated paper before creasing, ensuring the accuracy of the creasing position of the corrugated paper and improving the quality of creasing.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5 As shown, a corrugated cardboard box creasing device includes a support mechanism 1, a creasing mechanism 2 for applying pressure to the corrugated paper on the support mechanism 1, and a limiting mechanism 3 for adjusting and limiting the placement position of the corrugated paper on the support mechanism 1.

[0025] In this embodiment: the support mechanism 1 includes a workbench 12, a crossbeam 13 is provided at the upper end of the workbench 12, a cavity is provided inside the workbench 12 at the rear side of the crossbeam 13, a sliding groove communicating with the cavity is provided on the upper surface of the workbench 12, and a frame 11 is provided at the lower end of the workbench 12 to support the indentation mechanism 2 and the limiting mechanism 3.

[0026] In this embodiment: the creasing mechanism 2 includes a hydraulic telescopic rod 21 fixed to the upper end of the cross frame 13. Guide posts 22 are provided on both sides of the hydraulic telescopic rod 21. A mounting plate 23 is fixed to the lower end of the hydraulic telescopic rod 21 and the guide posts 22. A creasing knife 24 is installed on the lower side of the mounting plate 23. The extension length of the hydraulic telescopic rod 21 is adjusted according to the thickness of the corrugated paper and the depth of the creasing, so that the extension of the hydraulic telescopic rod 21 pushes the mounting plate 23 to move downward under the limit of the guide posts 22, and the creasing knife 24 performs a creasing operation on the corrugated paper.

[0027] In this embodiment: the limiting mechanism 3 includes a longitudinal limiting component, on which a transverse limiting component for laterally limiting the corrugated paper is provided. The longitudinal limiting component includes a longitudinally arranged lead screw 33, on which a sliding seat 31 is mounted. A limiting frame 32 is provided at the upper end of the sliding seat 31. A through groove 321 is provided on the limiting frame 32. The sliding seat 31 is located in the cavity of the worktable 12. The front end of the lead screw 33 passes through the worktable 12 and is connected to a handwheel 34. The lead screw 33 is rotatably connected to the worktable 12. The lead screw 33 is threadedly connected to the sliding seat 31. The sliding seat 31 is slidably connected to the worktable 12. By rotating the lead screw 33, the lead screw 33 pushes the limiting frame 32 on the sliding seat 31 to adjust the distance between it and the creasing knife 24, so that the distance between the rear edge of the corrugated paper and the creasing is fixed. The transverse limiting component includes left and right helical screws 35 provided on the rear side of the limiting frame 32. A transverse limiting seat 36 is provided on the worktable 35, passing through the through groove 321. One end of the left and right spiral screws 35 is connected to a servo motor 37. The left and right spiral screws 35 are rotatably connected to the limiting frame 32, and the transverse limiting seat 36 is threadedly connected to the left and right spiral screws 35. The transverse limiting seat 36 is slidably connected to the through groove 321. The lower end face of the limiting frame 32 and the lower end face of the transverse limiting seat 36 are flush with the upper end face of the worktable 12. The servo motor 37 drives the left and right spiral screws 35 to rotate, so that the transverse limiting seats 36 on the left and right spiral screws 35 move relative to each other under the limitation of the through groove 321. The spacing between the transverse limiting seats 36 is adjusted to match the width of the corrugated paper. A scale 4 is provided on the worktable 12 on one side of the limiting frame 32. The zero line of the scale 4 corresponds to the blade edge of the creasing knife 24, which facilitates the adjustment and confirmation of the position of the limiting frame 32 relative to the creasing knife 24.

[0028] The working principle and usage process of this utility model are as follows: By rotating the lead screw 33, the distance between the limit frame 32 on the sliding seat 31 and the creasing knife 24 is adjusted, so that the distance between the back side of the corrugated paper and the creasing is fixed. Then, the servo motor 37 drives the left and right spiral screws 35 to rotate, so that the transverse limit seats 36 on the left and right spiral screws 35 move relative to each other under the limit of the through groove 321, and the distance between the transverse limit seats 36 is adjusted to match the width of the corrugated paper. Then, the corrugated paper is placed between the transverse limit seats 36, with the back side of the corrugated paper aligned with the limit frame 32. The hydraulic telescopic rod 21 extends and pushes the mounting plate 23 to move downward under the limit of the guide post 22, so that the creasing knife 24 performs the creasing operation on the corrugated paper.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
