Description

Technical Field

[0001] The utility model relates to the technical field of product packaging, in particular to a device for one-step molding of paper shingles and die-cuts. Background Art

[0002] The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] Currently, the process for processing single-layer corrugated paper is as follows: first, the corrugated paper is slit, then cut and shaped, and finally, sealed and packaged. Because the slitting and cutting processes are performed by two separate machines, the processing efficiency is very low. Furthermore, the slit corrugated paper must be manually removed from the equipment and placed on the cutting machine for further cutting, which not only poses a safety risk to workers but also increases labor costs. Furthermore, placing the slit corrugated paper on the cutting machine can easily cause uneven edges, requiring manual trimming and cutting, resulting in material loss and low overall processing efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a device for one-step forming of paper tile die-cutting, which has a reasonable structure, high efficiency, high precision and reduces the loss of raw materials.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A device for corrugating and die-cutting paper in one step comprises a roll-changing device for placing a whole roll of paper, a corrugating device for making corrugated paper from paper, a die-cutting device for cutting the produced corrugated paper, and a paper receiving platform for collecting the cut corrugated paper; the die-cutting device comprises a die-cutting frame, a slitting mechanism arranged on the die-cutting frame for slitting the corrugated paper in the transverse direction, a paper feeding force roller for conveying the corrugated paper, and a cutting mechanism for cutting the arrived corrugated paper.

[0007] The above technical solution enables the die-cutting device to perform both slitting and cutting operations. This allows for quick and accurate completion of both tasks, significantly improving production efficiency while also ensuring precision, enhancing product quality, and reducing material loss. Furthermore, the die-cutting device can be used to perform slitting and cutting of various shapes and sizes, enhancing enterprise competitiveness.

[0008] In the improvement of the present utility model, the cutting mechanism includes a motor and a pair of sheet-breaking knife rollers and sheet-breaking bottom rollers that can cooperate with each other and are driven by the motor. The gear on the sheet-breaking knife roller shaft is meshed with the gear on the sheet-breaking bottom roller shaft. A motor gear is fixed on the output shaft of the motor, and the motor gear is meshed with the gear on the sheet-breaking bottom roller shaft.

[0009] In a further improvement of the present invention, the paper feed tension rollers include upper and lower conveyor rollers, each disposed above and below. A gear on the upper conveyor roller's shaft meshes with a gear on the lower conveyor roller's shaft, creating a gap between the upper and lower conveyor rollers. The corrugated paper is positioned within the gap between the upper and lower conveyor rollers. Thus, the upper and lower conveyor rollers cooperate to apply appropriate tension and traction, maintaining a flat surface during conveyance and preventing curling or skewing. The conveyance speed of the corrugated paper is also controlled, ensuring that the paper does not move too fast or too slow during die-cutting, and preventing slippage during conveyance.

[0010] In a preferred embodiment of the present invention, the die-cutting machine frame is equipped with an adjustment assembly for adjusting the gap between the sheet-breaking blade roller and the sheet-breaking bottom roller. This technical solution, by adjusting the gap, allows for better control over the cutting and conveying of corrugated paper, thereby reducing waste and downtime, and improving production efficiency. Furthermore, an appropriate gap ensures more accurate and uniform cutting of the corrugated paper, while also reducing wear and friction between the sheet-breaking blade roller and the sheet-breaking bottom roller, thereby extending the service life of the equipment.

[0011] In a preferred embodiment of the present invention, the adjustment components are provided in two symmetrically arranged groups. Each group includes a flange seat, an adjustment rod, a locking nut, and a lifting seat. The die-cutting frame is provided with a vertical chute, and the lifting seat is disposed within the chute. The flange seat is fixed to the top of the chute. A through hole is formed in the flange seat, through which the end of the adjustment rod is connected to the lifting seat. The locking nut is threadedly connected to the adjustment rod and is located above the flange seat. The shear roller is rotatably mounted on the lifting seat via a bearing. During use, the locking nut is loosened, the adjustment rod is moved up and down to adjust the position of the lifting seat, and the locking nut is tightened to secure the adjustment rod, thereby fixing the position of the lifting seat. This simple structure is convenient to use.

[0012] In the improved solution of the present utility model, the roll changing device includes a roll changing frame, a plurality of unwinding shafts rotatably connected to the roll changing frame and respectively used to fix the entire roll of paper, and a plurality of guide rollers.

[0013] In a further improved solution of the present invention, the corrugated paper device includes a shingle frame, on which preheating rollers for preheating and drying the paper are arranged in sequence along the traveling direction of the paper; a shingle mechanism applies pressure to the paper to deform the paper to form wavy corrugated paper.

[0014] In summary, the die-cutting device of the present invention can perform two operations, namely, slitting and cutting, thereby improving production efficiency, product quality, and reducing raw material loss. Furthermore, it can also perform slitting and cutting of various shapes and sizes according to different needs and requirements, thereby increasing the competitiveness of enterprises.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 As shown, the utility model is a device for corrugating and die-cutting paper in one step, comprising a roll-changing device 10 for placing a whole roll of paper 1, a corrugated paper device 20 for making corrugated paper 2 from the paper 1, a die-cutting device 30 for cutting the produced corrugated paper 2, and a paper receiving table 40 for collecting the cut corrugated paper.

[0022] Combine Figure 2As shown, the roll-changing device 10 includes a roll-changing frame 101, two unwinding shafts 102 rotatably connected to the roll-changing frame 101 for securing full paper rolls 1, and a plurality of guide rollers 103. Thus, two full paper rolls 1 are secured to corresponding unwinding shafts 102, with one full paper roll 1 serving as the current full paper roll 1a. During operation, the leading edge of the current full paper roll 1a sequentially passes over the plurality of guide rollers 103 before being wound into the corrugating device 20. When the current full paper roll 1a is exhausted and the next full paper roll 1b is required, the trailing edge of the full paper roll 1a is bonded to the leading edge of the next full paper roll 1b using double-sided tape.

[0023] Combine Figure 3 As shown, the corrugated paper machine 20 includes a shingling frame 21 and multiple paper guide rollers 22. Preheating rollers 23 are positioned sequentially along the paper 11's travel direction on the shingling frame 21 to preheat and dry the paper 1. A shingling mechanism 24 applies pressure to the paper 1, deforming it and forming the corrugated paper 2. The preheating rollers 23 preheat and dry the paper 1, ensuring it maintains a certain temperature and toughness for subsequent processing and forming. Furthermore, preheating the paper accelerates drying, improving production efficiency.

[0024] The shingle mechanism 24 comprises a pressure roller 243 and a pair of cooperating upper and lower shingle rollers 241 and 242 driven by the pressure roller 243. A first motor (not shown) driving the pressure roller 243 is mounted on the shingle frame 21. During the production of corrugated paper 2, the paper 1 is subjected to a certain amount of pressure and friction from the combined action of the upper and lower shingle rollers 241 and 242. This pressure and friction cause the paper 1 to deform, forming a wavy corrugated paper 2.

[0025] Combine Figure 4 As shown, the die-cutting device 30 includes a die-cutting frame 31, a slitting mechanism 32 arranged on the die-cutting frame 31 in sequence along the direction of travel of the corrugated paper for slitting the corrugated paper in the transverse direction, a paper feed force roller 33 for conveying the corrugated paper, and a cutting mechanism 34 for cutting the arriving corrugated paper. In this way, the die-cutting device can perform both slitting and cutting operations. This greatly improves production efficiency while ensuring the accuracy of slitting and cutting, enhancing product quality and reducing raw material loss. Furthermore, slitting and cutting can be performed in various shapes and sizes according to different needs, thereby increasing the company's competitiveness.

[0026] The slitting mechanism 32 is a prior art and has been disclosed in Chinese patent 201921913869.X, so it will not be described in detail here.

[0027] like Figure 4As shown, the cutting mechanism 34 includes a second motor (not shown) and a pair of cooperating shear rollers 341 and bottom shear rollers 342 driven by the second motor. A motor gear is fixed to the output shaft of the second motor and meshes with a gear on the shaft of the bottom shear roller 342. The gear on the shaft of the shear roller 341 meshes with a gear on the shaft of the bottom shear roller 342.

[0028] The paper feed tension rollers 33 consist of an upper conveyor roller 331 and a lower conveyor roller 332, positioned one above the other. A gap exists between the upper and lower conveyor rollers 331 and 332, through which the corrugated paper 2 passes. The gears on the shaft of the upper conveyor roller 331 mesh with the gears on the shaft of the lower conveyor roller 332. Furthermore, the motor gear of the second motor and the gear on the shaft of the lower conveyor roller 332 are linked by a gear mechanism.

[0029] In this way, the upper and lower conveyor rollers cooperate with each other to apply appropriate tension and traction to keep the corrugated paper flat during transportation to avoid curling or skewing. At the same time, the conveying speed of the corrugated paper is controlled to ensure that the corrugated paper will not be too fast or too slow during the die-cutting process, and it can also prevent the corrugated paper from slipping during transportation.

[0030] When the corrugated paper 2 enters the die-cutting device 30, if it needs to be cut into squares, the slitting mechanism 32 is first activated to slit the corrugated paper 2 along its width. The slit corrugated paper then passes through the gap between the upper and lower conveyor rollers and reaches the cutting mechanism 34. The shearing roller 341 and the shearing bottom roller 342 in the cutting mechanism 34 then cooperate to cut the corrugated paper 2. It should be noted that since each rotation of the shearing roller 341 constitutes one working cycle, the corresponding shearing roller 341 and the shearing bottom roller 342 need to be replaced when cutting squares of different sizes.

[0031] If the corrugated paper needs to be cut into circular or irregular shapes, the slitting mechanism 32 does not need to slit the corrugated paper along its width. Instead, the blades in the slitting mechanism 32 avoid the corrugated paper 2. The cutting mechanism 34 directly cuts the incoming corrugated paper 2. Similarly, each rotation of the sheet-breaking blade roller 341 constitutes one working cycle. Therefore, if different sizes of circular or irregular shapes need to be cut, the corresponding sheet-breaking blade roller 341 and sheet-breaking bottom roller 342 need to be replaced.

[0032] In addition, a sponge strip (not shown) is provided on the breaking knife roller 341. Like this, when the breaking knife roller 341 and the breaking bottom roller 342 apply pressure, they press the corrugated paper 2, making the corrugated paper taut and being able to pull the corrugated paper forward.

[0033] The die-cutting frame 31 is equipped with adjustment assemblies 35 for adjusting the gap between the sheet-breaking roller 341 and the sheet-breaking bottom roller 342. There are two sets of adjustment assemblies 35, symmetrically arranged. Adjusting the gap allows for better control over the cutting and conveying of corrugated paper, improving production efficiency. A proper gap ensures more accurate and uniform cutting of the corrugated paper, reduces wear and friction between the sheet-breaking roller and the bottom roller, and thus extends the service life of the equipment.

[0034] Each adjustment assembly 35 includes a flange seat 351 , an adjustment rod 352 , a locking nut 353 and a lifting seat 354 .

[0035] A vertical chute 355 is provided on the die-cutting frame 31. A lifting seat 354 is provided in the chute 355. A flange seat 351 is fixed to the top of the chute 355. A through hole is provided on the flange seat 351. The end of the adjusting rod 352 passes through the through hole and is connected to the lifting seat 354. The locking nut 353 is threadedly connected to the adjusting rod 352 and is located above the flange seat 351. The sheet-breaking knife roller 341 is rotatably provided on the lifting seat 354 via a bearing. When in use, unscrew the rotating locking nut 353, then move the adjusting rod 352 up and down to adjust the position of the lifting seat 354, determine the size of the gap between the sheet-breaking knife roller 341 and the sheet-breaking bottom roller 342, tighten the rotating locking nut 353 to fix the adjusting rod, thereby fixing the position of the lifting seat 354.

[0036] A hanging frame 36 is also provided on the die-cutting frame 31. The hanging frame 36 can facilitate the replacement of the shear cutter roller 341 and the shear bottom roller 342 each time.

[0037] In order to clearly illustrate the present invention, the cutting of 9-inch square padding paper and 10-inch round padding paper will be used as examples. In the actual production of 9-inch square padding paper, a whole roll of paper 1 enters the corrugated paper device 20. The width of the paper is 460 mm. After being pressed by a pair of upper and lower rollers 241 and 242 that cooperate with each other, a wavy corrugated paper 2 is formed. Afterwards, the corrugated paper 2 enters the die-cutting device 30. The slitting mechanism 32 slits the corrugated paper 2 along the width direction of the corrugated paper into two corrugated papers with a width of 230 mm. Afterwards, the sheet-breaking knife roller 341 and the sheet-breaking bottom roller 342 cooperate to cut the arrived slit corrugated paper longitudinally, completing the cutting of the 9-inch square padding paper. Afterwards, the cut 9-inch square padding paper is collected by the paper receiving platform 40. The paper receiving platform 40 is a prior art and will not be described in detail here. The paper receiving platform 40 can be set with a set number of padding papers. When the target number is reached, the belt on the paper receiving platform 40 accelerates to transport the padding papers away, and then proceeds to the next process.

[0038] In actual production of 10-inch round paper spacers, a full roll of paper 1 enters the corrugating device 20. A pair of cooperating upper and lower rollers 241 and 242 apply pressure to form a wavy corrugated paper 2. This corrugated paper 2 then enters the die-cutting device 30. The slitting mechanism 32 does not slit the corrugated paper 2. Instead, the sheet-breaking blade roller 341 and bottom sheet-breaking roller 342 cooperate to cut the incoming corrugated paper 2. The subsequent process is identical to that for 9-inch square paper spacers and will not be further described here.

[0039] In summary, the die-cutting device can perform both slitting and cutting operations, which can improve production efficiency, product quality, and reduce raw material loss. At the same time, it can also perform slitting and cutting of various shapes and sizes according to different needs, thereby increasing the competitiveness of enterprises.

[0040] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
