Description

Technical Field

[0001] This utility model belongs to the technical field of cardboard box production equipment, and in particular relates to a die-cutting device for the production of green printed corrugated cardboard boxes. Background Technology

[0002] Corrugated cardboard boxes are one of the most common packaging products at present. Because they are used for product packaging, corrugated cardboard boxes need to be aesthetically pleasing and easily identifiable. Therefore, different colored corrugated cardboard boxes are used, and different patterns or slogans are printed on the outer walls of the corrugated cardboard boxes to improve their aesthetics and identifiability.

[0003] A Chinese patent application (or patent) with publication number CN220883539U discloses a die-cutting machine for carton production, including a worktable, a frame assembly disposed on the top surface of the worktable, a cylinder disposed on the frame assembly, and limiting parts symmetrically slidably disposed on the worktable. A blade holder assembly is disposed at the end of the cylinder, and the blade holder assembly is positioned directly opposite the cardboard on the worktable. The worktable has slots, within which multiple support parts are spaced apart, and the cardboard is placed on the support parts. In this invention, the spaced support parts within the slots prevent the blade from colliding with the worktable, reducing the damage rate of the equipment and increasing the service life of the blade. The symmetrically slidably disposed limiting parts can position the cardboard placed at the cutting position, preventing cutting deviations. The frame assembly provides a fixing function for the cylinder, ensuring stability during operation.

[0004] The aforementioned die-cutting machine for carton production includes a support frame with an upper and lower roller. A spring is installed at the top of the upper roller to adjust its height. The roller is extremely heavy and is suspended from the support frame by the spring. The thickness of the carton itself supports the upper roller, creating a gap between it and the lower roller for conveying the carton. However, due to the weight of the upper roller and the limited elasticity of the spring, it exerts significant pressure on the carton, causing it to flatten and lose its original shape. Furthermore, the collection device includes a suction hood located below the support and a storage tank connected to the end of the suction hood. The debris generated during carton cutting is in the form of strips or sheets of paper. When this debris enters the storage tank through the suction hood, it causes blockage at the small-diameter end of the suction hood. The loose carton debris also occupies a large amount of storage space in the storage tank, hindering proper storage. To address these issues, we provide a green die-cutting device for producing printed corrugated boxes. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, please refer to Figure 1-4 This utility model is a die-cutting device for the production of green printed corrugated cardboard boxes, including a machine base 2 and a base 1 for supporting the machine base 2. At the same time, a die-cutting component 4 is installed in the middle of the upper side wall of the machine base 2. The green printed corrugated cardboard on the machine base 2 can be die-cut by using the suspended die-cutting component 4.

[0032] Specifically, the frame 401 in the die-cutting assembly 4 is installed above the middle of the machine base 2. The frame 401 has a mounting hole 401a for mounting the mounting bracket 404a. A hydraulic rod 404 is suspended inside the mounting bracket 404a. A lifting plate 403 is installed on the shaft end of the hydraulic rod 404. The bottom side wall of the lifting plate 403 is connected to the blade holder 402 through a spring rod 403a. A die-cutting blade 402a is installed on the bottom side wall of the blade holder 402.

[0033] Furthermore, four support columns 101 are welded to the upper side wall of the base 1, and the base 1 is welded to the bottom side wall of the machine platform 2 through the support columns 101. The upper side wall of the machine platform 2 is also inlaid with a table plate 201.

[0034] The operation process of this embodiment is as follows: When the green printed corrugated cardboard is transported onto the table 201, the hydraulic rod 404 in the die-cutting assembly 4 works, which drives the lifting plate 403 on the shaft end to move down. When it moves down, the blade holder 402 and the die-cutting blade 402a at its bottom also move down and come into contact with the green printed corrugated cardboard. When the die-cutting blade 402a comes into contact with the green printed corrugated cardboard, the spring rod 403a is compressed to protect the die-cutting blade 402a. In the no-load state, when the spring rod 403a is compressed, the die-cutting blade 402a comes into contact with the table 201 but does not apply excessive pressure. This state provides the operator with sufficient reaction time to avoid the die-cutting blade 402a from causing excessive impact on the table 201, which would cause the blade to roll. When the green printed corrugated cardboard is being die-cut, the spring rod 403a is continuously compressed to the minimum until the die-cutting blade 402a completes the die-cutting work on the green printed corrugated cardboard.

[0035] Example 2, please refer to Figure 5 Based on the first specific embodiment, a feeding component 3 is also provided. The feeding component 3 includes a lower drive roller 301 and an upper drive roller 302. The upper drive roller 302 can move up and down with the cooperation of the screw 305 and the bushing 304, and the distance of movement is adjustable. Thus, it can clamp and deliver green printed corrugated cardboard of different thicknesses.

[0036] Specifically, the upper drive roller 302 in the feeding assembly 3 is positioned directly above the lower drive roller 301. Both shaft ends of the upper drive roller 302 are provided with limit sleeves 303, and the upper sidewall of the limit sleeve 303 is welded with a column sleeve 303a. The column sleeve 303a is internally threaded with a screw 305. The bottom shaft end of the screw 305 is rotatably connected to the rotating groove 304a in the bushing 304. The bushing 304 is then sleeved on the shaft end of the upper drive roller 302.

[0037] Furthermore, a vertical plate 202 is welded to the left side wall of the machine base 2, and a shaft hole 203 for connecting with the lower drive shaft 301 is provided in the vertical plate 202. The shaft hole 203 is rotatably connected to the shaft end of the lower drive roller 301 through a bearing 301a. A shaft groove 202a for engaging the limiting sleeve 303 is provided in the vertical plate 202, and a top hole 202b for engaging the column sleeve 303a is provided at the top of the shaft groove 202a.

[0038] The operation process of this embodiment is as follows: When it is necessary to adjust the distance between the upper drive roller 302 and the lower drive roller 301, hold the top of the screw 305 and rotate the screw 305. When the screw 305 moves up and down within the sleeve 303a, the bushing 304 at the bottom of the screw 305 also moves, thereby pulling the upper drive roller 302 to move. After adjusting the distance, place the green printed corrugated cardboard that needs to be die-cut between the lower drive roller 301 and the upper drive roller 302. Then start the lower drive roller 301 and the upper drive roller 302 to clamp and deliver the green printed corrugated cardboard.

[0039] Example 3, please refer to Figure 6 Based on specific embodiments one and two, a recycling component 5 is also provided. The recycling box 501 in the recycling component 5 is provided with a squeezing plate 502 and a pneumatic rod 503. The squeezing plate 502 can be pushed to move within the recycling box 501 by using the pneumatic rod 503. When it moves, it can compress the paper scraps that fall into the recycling box 501.

[0040] Specifically, a compression plate 502 is slidably connected inside the recycling box 501 in the recycling component 5, and a pneumatic rod 503 is detachably fixedly installed on the side wall of the two shaft ends of the compression plate 502, and the pneumatic rod 503 is inserted into the side wall of the recycling box 501.

[0041] Furthermore, the upper side wall of the recycling box 501 is detachably and fixedly connected to the bottom side wall of the machine base 2. The recycling box 501 has a recycling groove 501a inside, and the center of the front and rear side walls of the recycling groove 501a has a side sliding groove 501b. The shaft end of the extrusion plate 502 is slidably connected to the side sliding groove 501b.

[0042] The operation process of this embodiment is as follows: when paper scraps fall into the recycling box 501, the pneumatic rod 503 operates, pushing the pressing plate 502 on its shaft end to move, thereby pushing the paper scraps in front of the pressing plate 502 towards one side of the recycling box 501 and compressing them. Then the pneumatic rod 503 retracts in the opposite direction, driving the pressing plate 502 to move back, pushing the paper scraps behind the pressing plate 502 towards one side of the recycling box 501 and compressing them.
