Technical Field

[0001] This utility model relates to the field of cardboard processing technology, and in particular to a trimming structure for a direct-printing paper-feeding cardboard box and an integrated machine for trimming and pressing cardboard boxes. Background Technology

[0002] In the corrugated box manufacturing industry, direct-printing corrugated box production equipment is widely used due to its efficient and precise printing and processing capabilities. Among these processes, trimming the printed cardboard is a crucial step, aiming to remove burrs, excess material, or positioning allowances generated during printing or pre-processing to ensure the final box's dimensions are accurate and the edges are neat and aesthetically pleasing. Currently, existing corrugated box trimming equipment on the market typically uses a shearing method with upper and lower molds working together. However, these traditional structures have some inherent drawbacks. This layout results in a less compact overall structure, occupying a large amount of space laterally or longitudinally, which is not conducive to the intensive layout of the production line. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide a trimming structure for a direct-printing paper-feed carton that is compact and convenient for trimming cardboard.

[0004] The second aspect of this utility model provides a compact and convenient integrated machine for trimming and creasing cardboard boxes.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] The first aspect of this utility model provides a trimming structure for a direct-printing paper-feeding carton, comprising: a base frame, wherein a plurality of first slide rails are arranged on the base frame along the paper feeding direction, the first slide rails are arranged on the left and right side walls of the base frame, and a first slider is arranged on the first slide rail that can slide relative to it, a mounting frame is arranged between two of the first sliders, a plurality of top plates are arranged on one side of the mounting frame, a cutter is arranged on the mounting frame that can be offset from the top plates and can cooperate with the top plates to trim the paperboard, and a drive structure is arranged between the cutter and the mounting frame that can drive the cutter to move along the mounting frame.

[0007] The mounting bracket includes a support plate connected to the first slider. A first horizontal support rod and a second horizontal support rod are arranged between the two support plates. The first horizontal support rod is located above the second horizontal support rod, and the first horizontal support rod and the second horizontal support rod are spaced apart front and rear. A plurality of top plates are arranged on one side of the second horizontal support rod, and the driving structure is arranged on the first horizontal support rod.

[0008] The drive structure includes a second slide rail mounted on a second cross brace, a second slider mounted on the second slide rail that can slide along it, a mounting seat mounted on the second slider, a cutter mounted on the mounting seat that can rotate relative to it, and a drive assembly that can drive the second slider to slide between the second cross brace and the second slider.

[0009] The drive assembly includes a connecting frame mounted on a support plate, a first roller mounted on the connecting frame, a second connecting plate mounted on the second cross brace, a first drive motor mounted on the second connecting plate, a first rotating wheel mounted on the output shaft of the first drive motor, a first transmission belt mounted between the first rotating wheel and the first roller, and a first auxiliary wheel mounted on the second connecting plate that can contact the first transmission belt and keep the first transmission belt taut.

[0010] The cutter can be connected to the mounting base via a locking member, and the mounting base is provided with multiple strip holes through which the locking member can pass.

[0011] The top plate includes a base connected to the second cross brace, and a top block is provided on the base. On the side of the top block adjacent to the cutter, a protrusion extends upward and fits against one side of the cutter.

[0012] The cutter includes a frustum-shaped cutter body, and a cutter portion is provided on one edge of the cutter body adjacent to the top plate.

[0016] Compared with existing technologies, this utility model has the following advantages:

[0017] When in use, the cardboard extends from the mounting frame. Due to the misalignment of the cutter and the top plate, the top plate supports the lower surface of the cardboard while the cutter acts on the upper surface, forming a cutting pattern of upper cutting and lower support. As the cutter moves along the mounting frame, it cuts off the excess parts of the cardboard edges, making it easy to cut. At the same time, the drive structure is set inside the mounting frame, which does not occupy the space of the base frame, making the whole structure more compact and occupying less space.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] like Figures 1 to 8As shown, a trimming structure for a direct-printing paper-feeding carton includes: a base frame 1, on which a plurality of first slide rails 11 are arranged along the paper feeding direction, the first slide rails 11 being arranged on the left and right side walls of the base frame 1, and a first slider 12 that can slide relative to the first slide rail 11 being arranged on the first slide rail 11, a mounting frame 13 being arranged between two of the first sliders 12, a plurality of top plates 14 being arranged on one side of the mounting frame 13, and a cutter 2 that can be offset from the top plates 14 and cooperate with the top plates 14 to trim the paperboard, and a drive structure 3 that can drive the cutter 2 to move along the mounting frame 13 being arranged between the cutter 2 and the mounting frame 13.

[0029] When this utility model is in use, the cardboard extends out from the mounting frame 13. Since the cutter 2 and the top plate 14 are misaligned, the top plate 14 supports the lower surface of the cardboard and the cutter 2 acts on the upper surface during operation, forming a cutting pattern of upper cutting and lower support. As the cutter 2 moves along the mounting frame 13, the cutter 2 cuts off the excess part of the edge of the cardboard, making it convenient for cutting. At the same time, the drive structure 3 is set inside the mounting frame 13, which does not occupy the space of the base frame 1, making the whole structure more compact and occupying less space.

[0030] The mounting frame 13 includes a support plate 131 connected to the first slider 12. A first horizontal support rod 132 and a second horizontal support rod 133 are arranged between the two support plates 131. The first horizontal support rod 132 is located above the second horizontal support rod 133, and the first horizontal support rod 132 and the second horizontal support rod 133 are spaced apart. Multiple top plates 14 are arranged on one side of the second horizontal support rod 133. The drive structure 3 is mounted on the first horizontal support rod 132. The support plate 131 is directly fixed to the first slider 12, ensuring that the mounting frame 13 and the first slide rail 11 always move parallel to each other. The first horizontal support rod 132 is located above the second horizontal support rod 133 and spaced apart, forming multiple supports and increasing the supporting force of the two support plates 131. This makes the drive structure 3 and the cutter 2 more stably supported, preventing displacement of the cutter 2.

[0031] The drive structure 3 includes a second slide rail 31 mounted on the second crossbar 133. A second slider 32, capable of sliding along the second slide rail 31, is mounted on the second slider 32. A mounting base 33 is mounted on the second slider 32, and a cutter 2, capable of rotating relative to the mounting base 33, is mounted between the second crossbar 133 and the second slider 32. A drive assembly 34, capable of driving the second slider 32 to slide, is also provided between the second crossbar 133 and the second slider 32. The mounting base 33 facilitates the fixing and positioning of the cutter 2. Simultaneously, the drive assembly 34 causes the second slider 32 to move along the second slide rail 31, thereby causing the cutter 2 to slide relative to the second crossbar 133.

[0032] The drive assembly 34 includes a connecting frame 341 mounted on a support plate 131, a first roller 342 mounted on the connecting frame 341, a second connecting plate 343 mounted on the second cross brace 133, a first drive motor 344 mounted on the second connecting plate 343, a first rotating wheel 345 mounted on the output shaft of the first drive motor 344, a first transmission belt 346 positioned between the first rotating wheel 345 and the first roller 342, and a first auxiliary wheel 347 mounted on the second connecting plate 343 that can contact the first transmission belt 346 and keep the first transmission belt 346 taut. When the first drive motor 344 starts, it drives the first rotating wheel 345 to rotate. The rotation of the first rotating wheel 345 drives the first transmission belt 346 to move. The first transmission belt 346 then drives the two first rollers 342 to move accordingly. The closed-loop synchronous belt drive formed by the first rollers 342, the first rotating wheel 345, the first transmission belt 346, and the first auxiliary wheel 3747 smoothly and accurately converts the rotational motion output by the first drive motor 344 into the linear displacement of the second slider 32. The second slider 32 can then drive the cutter 2 to move along the second cross brace 133. The first auxiliary wheel 347 keeps the first transmission belt 346 taut in real time, eliminating backlash and slippage.

[0033] The cutter 2 can be connected to the mounting base 33 via a locking element, and the mounting base 33 is provided with multiple slotted holes 331 through which the locking element can pass. The locking element is a screw or a locking pin, which facilitates the installation of the cutter 2 onto the mounting base 33. The multiple slotted holes 331 allow the height position of the cutter 2 relative to the top plate 14 to be changed, which can be adjusted according to the cardboard of different thicknesses, thus making it more widely applicable.

[0034] The top plate 14 includes a base 141 connected to the second cross brace 133. A top block 142 is provided on the base 141. A protrusion 1421 extending upward and conforming to one side of the cutter 2 is provided on the side of the top block 142 adjacent to the cutter 2. The protrusion 1421 has a slope to lift the cardboard, which facilitates cutting the cardboard.

[0035] The cutter 2 includes a frustum-shaped cutter body 21, and a cutter portion 22 is provided on one side edge of the cutter body 21 adjacent to the top plate 14 to facilitate cutting the cardboard.

[0036] A movable component 4 is provided between the first slider 12 and the base frame 1, which can drive the first slider 12 to slide along the first slide rail 11. The movable component 4 facilitates the sliding of the first slider 12 along the first slide rail 11, can be adjusted according to the length of the cardboard, and can more accurately cut off the excess part of the cardboard.

[0037] The movable component 4 includes multiple rotating bearings 41 spaced apart on the base frame 1. A mounting plate 42 is mounted on the base frame 1, and a second drive motor 43 is mounted on the mounting plate 42. A second rotating wheel 44 is mounted on the output shaft of the second drive motor 43. A second transmission belt 45 is connected between the second rotating wheel 44 and the multiple rotating bearings 41. When the second drive motor 43 starts, it drives the second rotating wheel 44 to rotate. The rotation of the second rotating wheel 44 causes the second transmission belt 45 and the rotating bearings 41 to move. When the second transmission belt 45 moves, it causes the first slider 12 to reciprocate on the first slide rail 11, facilitating the adjustment of the cutter 2's position relative to the base frame 1.

[0038] A carton trimming and creasing machine includes a trimming structure 100 for a direct-printing carton as described above. The base frame 1 is further equipped with a first creasing structure 5 and a second creasing structure 6 that cooperate in pressing the horizontal fold lines and carton height lines. When this invention is in use, the first creasing structure 5 and the second creasing structure 6 work together to press the horizontal fold lines and carton height lines. During this process, the first creasing structure 5 and the second creasing structure 6 clamp and position the cardboard, facilitating the operation of the trimming structure 100 for the direct-printing carton and removing excess portions of the cardboard.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
