[0001] This utility model relates to the field of corrugated cardboard box processing technology, specifically a cutting device for precise forming of corrugated cardboard boxes. Background Technology
[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. Due to their superior performance and ease of processing, corrugated boxes have gradually replaced wooden crates and other transport packaging containers, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are considered environmentally friendly products, benefiting both the environment and the loading and unloading process. In the processing of corrugated boxes, cutting equipment is used to cut the corrugated cardboard to specified dimensions, facilitating subsequent production into precisely sized corrugated boxes.
[0003] Some cutting equipment used for precision forming of corrugated boxes can only cut corrugated cardboard of a single size. When it is necessary to produce corrugated boxes of different specifications, the cutting blades need to be changed, which makes it inconvenient to use. Therefore, it does not meet the existing needs. In response, we have proposed a cutting equipment for precision forming of corrugated boxes. Utility Model Content

[0006] Preferably, the driving structure includes a support plate, which is fixedly disposed on the side of the two strip-shaped through slots that are far apart from each other and located at the bottom end of the worktable. A bidirectional threaded rod is driven and connected between the two support plates on the side that are close to each other through a first motor. A slide rod is fixedly connected below the bidirectional threaded rod and between the two support plates.
[0007] Preferably, a connecting seat is connected between both sides of the outer surface of the bidirectional threaded rod and the slide rod. The internal thread of the connecting seat near the upper end is connected to the bidirectional threaded rod, and the internal thread of the connecting seat near the bottom end is slidably connected to the slide rod. The bottom ends of the two corrective seats are respectively fixedly connected to the upper ends of the two connecting seats.
[0008] Preferably, the limiting structure includes a limiting seat, which is fixedly connected to the top end of the cutting blade. The limiting seat has a sliding groove that is slidably connected to the outer surface of the positioning rod near the upper end. Above the sliding groove and inside the limiting seat, a driving cavity is provided. A limiting rod that extends through to the outer side of the upper end of the limiting seat is movably connected inside the driving cavity.
[0009] Preferably, a sliding plate that is slidably connected to the outer surface of one end of the limiting rod located inside the driving cavity is fixedly connected to the limiting rod. A spring is fixedly connected between the upper end of the sliding plate and the top end of the inner wall of the driving cavity, and the spring is wound around the outer surface of the limiting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model involves pulling the limiting rod at the upper end of the limiting seat, causing the limiting rod to drive the sliding plate to compress the spring, and causing the bottom end of the limiting rod to disengage from the current limiting groove, thus releasing the limiting seat. Then, the limiting seat moves along the outer surface of the positioning rod, and drives the cutting blade to slide along the outer surface of the fixed roller. Then, according to the pointer pointing to the scale line, the position between each cutting blade is precisely adjusted and controlled. After the adjustment is appropriate, the pulling of the limiting rod is released, causing the spring to push the limiting rod to engage with the corresponding limiting groove, thereby fixing the position of the cutting blade. This allows for flexible adjustment of the distance between each cutting blade when producing corrugated boxes of different specifications.
[0014] 2. This utility model places corrugated paper on the workbench and between two straightening seats. Then, the first motor is started to drive the bidirectional threaded rod to rotate. As the bidirectional threaded rod rotates, the thread drives the connecting seats on both sides of the outer surface to move towards each other under the limit of the slide rod. This causes the straightening seats connected to the connecting seats to move closer to each other, so that the corrugated paper can be clamped and straightened according to its size, avoiding deviations in the size of the cut paper during cutting.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1 to 4This utility model provides an embodiment of a cutting device for precise forming of corrugated cardboard boxes, including a workbench 1. Symmetrical strip-shaped through slots 101 are provided on the front and back of one side of the upper end of the workbench 1. The interior of each strip-shaped through slot 101 is driven and connected to a straightening seat 3 through a driving structure 2. On one side of the straightening seat 3 and on both sides above the workbench 1, guide rollers 5 are driven by a second motor 4. Between the two guide rollers 5 and on the workbench 1, a cutting groove 102 is provided. Fixing plates 6 are fixedly provided on the front and back sides of the cutting groove 102. A fixing roller 7 is fixedly connected between the bottom ends of the two fixing plates 6 that are close to each other. A plurality of cutting blades 8 are slidably connected to the outer surface of the fixing roller 7. A positioning rod 9 is fixedly connected above the fixing roller 7 and between the upper ends of the two fixing plates 6. The upper end of each cutting blade 8 is connected to the positioning rod 9 through a limiting structure 10.
[0022] The limiting structure 10 includes a limiting seat 1001, which is fixedly connected to the top end of the cutting blade 8. A groove 1002 is slidably connected to the outer surface of the positioning rod 9 near the upper end of the limiting seat 1001. A driving cavity 1003 is formed above the groove 1002 and inside the limiting seat 1001. A limiting rod 1004, extending through to the outer side of the upper end of the limiting seat 1001, is movably connected inside the driving cavity 1003. The outer surface of one end of the limiting rod 1004 inside the driving cavity 1003 is fixedly connected to... A sliding plate 1005 is slidably connected to the drive cavity 1003. A spring 1006 is fixedly connected between the upper end of the sliding plate 1005 and the top end of the inner wall of the drive cavity 1003. The spring 1006 is wrapped around the outer surface of the limiting rod 1004. The bottom end of the limiting rod 1004 penetrates the drive cavity 1003 and extends into the interior of the slide groove 1002. Several limiting grooves 901 are evenly spaced on the upper end of the positioning rod 9. One end of the limiting rod 1004 that extends into the interior of the slide groove 1002 is inserted into the corresponding limiting groove 901.
[0023] By pulling the limiting rod 1004 at the upper end of the limiting seat 1001, the limiting rod 1004 causes the sliding plate 1005 to compress the spring 1006, and the bottom end of the limiting rod 1004 disengages from the current limiting groove 901, releasing the limiting seat 1001. Then, the limiting seat 1001 moves along the outer surface of the positioning rod 9, and drives the cutting blade 8 to slide along the outer surface of the fixed roller 7. Several scale lines 902 are evenly spaced on one side of the outer surface of the positioning rod 9, and one side of the outer surface of the limiting seat 1001... A side groove 1007 is provided at the corresponding position of the slide groove 1002. A pointer 1008 is fixedly connected to the top of the side groove 1007. The pointer 1008 is movably located on the front surface of the scale line 902. Then, according to the indication of the pointer 1008 on the scale line 902, the position between each cutting blade 8 is precisely adjusted and controlled. After the adjustment is appropriate, the pull on the limit rod 1004 is released, so that the spring 1006 pushes the limit rod 1004 to insert into the corresponding limit groove 901, thereby fixing the position of the cutting blade 8.
[0024] The drive structure 2 includes a support plate 201, which is fixedly disposed on one side of the two strip-shaped through slots 101 that are far apart from each other and located at the bottom of the workbench 1. A bidirectional threaded rod 203 is driven and connected between the two support plates 201 on the side that are close to each other through a first motor 202. A slide rod 204 is fixedly connected below the bidirectional threaded rod 203 and between the two support plates 201. Connecting seats 205 are connected between the two sides of the outer surface of the bidirectional threaded rod 203 and the slide rod 204. The inner thread of the connecting seat 205 near the upper end is connected to the bidirectional threaded rod 203, and the inner thread of the connecting seat 205 near the bottom end is slidably connected to the slide rod 204. The bottom ends of the two straightening seats 3 are fixedly connected to the upper ends of the two connecting seats 205 respectively.
[0025] By starting the first motor 202, the bidirectional threaded rod 203 is driven to rotate. As the bidirectional threaded rod 203 rotates, the thread drives the connecting seats 205 on both sides of the outer surface to move towards each other under the limit of the slide rod 204. This causes the straightening seats 3 connected to the connecting seats 205 to move closer to each other, so that the corrugated paper can be clamped and straightened according to its size, thus avoiding deviations in the size of the cut paper during cutting.
[0026] When using the cutting equipment for precise corrugated cardboard box forming, by pulling the limiting rod 1004 at the upper end of the limiting seat 1001, the limiting rod 1004 causes the sliding plate 1005 to compress the spring 1006, and the bottom end of the limiting rod 1004 disengages from the current limiting groove 901, releasing the limitation on the limiting seat 1001. Then, the limiting seat 1001 moves along the outer surface of the positioning rod 9, and drives the cutting blade 8 to slide along the outer surface of the fixed roller 7. Then, according to the pointer 1008 pointing to the scale line 902, the position between each cutting blade 8 is precisely adjusted and controlled. After the adjustment is appropriate, the pulling of the limiting rod 1004 is released, so that the spring 1006 pushes the limiting rod 1004 to engage with the corresponding limiting groove 901, thereby fixing the position of the cutting blade 8. This allows for flexible adjustment of the distance between each cutting blade 8 when producing corrugated cardboard boxes of different specifications.
[0027] After the positions of the cutting blades 8 are properly adjusted, the corrugated paper is placed on the workbench 1 and between the two straightening seats 3. Then, the first motor 202 is started to drive the bidirectional threaded rod 203 to rotate. As the bidirectional threaded rod 203 rotates, the thread drives the connecting seats 205 on both sides of the outer surface to move towards each other under the limit of the slide rod 204. This causes the straightening seats 3 connected to the connecting seats 205 to move closer to each other, so that the corrugated paper can be clamped and straightened according to its size, avoiding deviations in the cut size during cutting. The straightened corrugated paper is driven by the guide roller 5 and moves towards one side of the cutting blade 8. Then, the cutting blade 8 cuts it into corrugated cardboard of appropriate size, which makes it easy to assemble the corrugated cardboard into corrugated boxes of precise size.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
