Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to an online cardboard cutting device. Background Art

[0002] After being processed by production equipment, cardboard is usually in large sheets or long strips and needs to be cut into corresponding shapes before it can be carefully classified and applied.

[0003] Using a cutter to directly cut the cardboard is a more efficient cutting method, and the edge of the cut cardboard is relatively smooth, flat, and burr-free. In the existing cutter cutting method, the cutter is mostly an integrated structure with a fixed position and a fixed cutting length. For the equipment that is manually operated for cutting, when the cutting length needs to be adjusted, the cardboard can be manually moved to adjust it (adjusting the overlapping length of the cardboard and the cutter is the cutting length). When it is necessary to cut directly inside the cardboard (through multiple cuts, a fixed shape is dug out inside the cardboard), and the length to be cut is less than or greater than the length of the cutter, the only option is to replace the cutter. However, replacing the cutter is a very cumbersome process, and a cumbersome debugging process is required after replacement. Therefore, a cutting device that can easily adjust the cutting length can be designed. Utility Model Content

[0027] Example

[0028] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 6 As shown, the cardboard online cutting device of this embodiment includes an operating table 11, a cutting device arranged on the operating table 11, a first driving device for driving the cutting device to move in a vertical direction, and a bracket 12 for supporting the cutting device; the cutting device includes a pair of cutters 21 arranged to fit each other, and a connecting piece for connecting the pair of cutters 21; the cutters 21 are beveled blades, and the edges of the pair of cutters 21 fit each other. Specifically, when in use, the cardboard is placed on the operating table 11 for cutting operation. During the cutting process, the driving device drives the cutters 21 to move in a vertical direction to cut the cardboard. The total length formed by the pair of cutters 21 can be adjusted by adjusting the overlap of the pair of cutters 21, and then the cutting length can be adjusted. In this way, the cardboard can be cut directly inside without cutting the edge of the cardboard, so the corresponding shape can be cut directly inside the cardboard, and the cutting length can be adjusted within a certain range according to the required cutting length. Since the pair of cutters 21 are both beveled blades and fit together, the shapes cut by the overlapping part and the non-overlapping part of the cutters 21 are basically the same, which will not affect the quality of the product.

[0029] In this embodiment, the cutters 21 are provided with a slide bar 22 and a slide groove 23 on the side close to each other, and the slide bar 22 of one cutter 21 is slidably arranged in the slide groove 23 of the other cutter 21. Specifically, through the cooperation of the slide groove 23 and the slide bar 22, the fit of the pair of cutters 21 can be ensured as much as possible, and a good parallelism can be maintained when the cutters 21 slide relative to each other for adjustment.

[0030] The connecting member in this embodiment includes a first connecting plate 24 disposed on the upper side of the cutter 21, a second connecting plate disposed between a pair of first connecting plates 24, a first long through hole 25 provided in the first connecting plate 24, a second long through hole provided in the second connecting plate, and a fastening bolt 27 provided through the first through hole 25 and the second through hole; the second connecting plate is connected to the first driving device. Specifically, when adjusting, it is only necessary to loosen the fastening bolt 27, then move the pair of cutters 21 so that the total length formed by them reaches the required length, and then tighten the fastening bolt 27.

[0031] The connecting member in this embodiment also includes a connecting block 28 connected to the upper side of the second connecting plate, and a connecting rod 29 connected to the connecting block 28; the first driving device includes a hydraulic cylinder 13 vertically and downwardly arranged, and the telescopic rod of the hydraulic cylinder 13 is connected to the connecting rod 29; the hydraulic cylinder 13 is connected to the bracket 12. Specifically, the hydraulic cylinder 13 can well drive the cutter 21 to move up and down. For cardboards that do not require a large cutting force, electric push rods, pneumatic push rods and other structures can also be used.

[0032] The telescopic rod of the hydraulic cylinder 13 in this embodiment is rotatably connected to the connecting rod 29; and also includes a second driving device for driving the connecting rod 29 to rotate. The second driving device includes a worm wheel 31 provided on the outer wall of the connecting rod 29, a worm 32 meshing with the worm wheel 31, and a motor 33 for driving the worm 32 to rotate; the motor 33 is fixedly connected to the telescopic rod of the hydraulic cylinder 13. Specifically, when cutting, it is possible to encounter a situation where the cutting line needs to be adjusted. At this time, the worm 32 can be driven to rotate by the motor 33, and then the turbine can be driven to rotate, so that the cutter 21 is driven to rotate on the horizontal plane through the connecting rod 29, the connecting block 28, the second connecting plate and the first connecting plate 24, so as to achieve the purpose of adjusting the direction of the cutting line.

[0033] In this embodiment, a connecting piece 41 is also included which is detachably arranged at the end of the cutter 21, and a cutting edge is provided on the lower side of the connecting piece 41. A slot 210 is provided at the end of the cutter 21, and a block 42 is provided at both ends of the connecting piece 41; the block 42 is clamped in the slot 210. Specifically, by providing the connecting piece 41, the cutter 21 can be connected through the connecting piece 41, and by providing connecting pieces 41 of different shapes, and cutting devices of different lengths and numbers, a corresponding shape can be cut out on the cardboard at one time (the connecting piece 41 can also be cut), and there is no need to produce a specific cutter 21 according to a specific shape. It can reduce production costs and facilitate cost reduction in the research and development stage. Bolts can be used to fix the block 42 in the slot 210.

[0034] In summary, the cardboard online cutting device of this embodiment, when in use, places the cardboard on the operating table 11 for cutting operation. During the cutting process, the driving device drives the cutter 21 to move in the vertical direction to cut the cardboard. The total length formed by the pair of cutters 21 can be adjusted by adjusting the overlap of the pair of cutters 21, and then the cutting length can be adjusted. This can directly cut inside the cardboard without cutting the edge of the cardboard, so the corresponding shape can be directly cut inside the cardboard, and the cutting length can be adjusted within a certain range according to the required cutting length. Since the pair of cutters 21 are both beveled and fit together, the shapes cut by the overlapping part and the non-overlapping part of the cutter 21 are basically the same, which will not affect the quality of the product.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
