Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a continuous die-cutting machine for heavy-duty carton production. Background Technology
[0002] In the cardboard box manufacturing industry, heavy-duty cardboard boxes are widely used for packaging various large products and heavy objects due to their high strength and high compression resistance. However, existing die-cutting machines for heavy-duty cardboard box production have revealed many problems in practical applications, seriously restricting the improvement of production efficiency and product quality.
[0003] Firstly, there's the issue of blade wear and precision. Traditional heavy-duty carton die-cutting machines are typically equipped with only a single cutting blade or a combination of blades with fixed cutting positions. Over long production cycles, the complex and diverse cutting requirements of cartons lead to frequent use of specific cutting positions, resulting in accelerated wear on those blades. Worn blades significantly reduce cutting precision, causing burrs and dimensional deviations on the edges of the cut cartons. This not only affects the aesthetics of the cartons but also reduces their packaging performance and increases the defect rate. Frequent blade replacements, in turn, lead to prolonged downtime, significantly reduced production efficiency, and a substantial increase in production costs.
[0004] Secondly, there's the issue of waste management. Heavy-duty cardboard boxes generate a significant amount of waste during die-cutting, such as paper scraps and trimmings. This waste easily adheres to the surface of the boxes or spills inside the equipment. Waste adhering to the boxes not only affects the product's appearance but can also cause contamination during subsequent packaging, impacting product quality. Waste spilled inside the equipment, if not cleaned promptly, will accumulate on the worktable, hindering normal operation and potentially damaging equipment components, increasing maintenance costs and repair frequency. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a continuous die-cutting machine for heavy-duty cardboard box production, which aims to improve the problems in the prior art where frequent use of a certain cutting position of the cutting tool leads to a decrease in the accuracy of the cutting tool, resulting in the replacement of the entire cutting tool, and the waste material after cutting heavy-duty cardboard boxes sticking to the cardboard box.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a continuous die-cutting machine for heavy-duty carton production, comprising a support frame, a working frame installed inside the support frame, a control box installed outside the support frame, a cutting mechanism installed inside the working frame, and a cleaning mechanism installed inside the working frame;
[0007] The cutting mechanism consists of a first cutting area, a second cutting area and a third cutting area. The first cutting area includes a support plate, which is installed on the upper surface of the work frame. An active roller and a cutting roller are installed between the two support plates.
[0008] As a further description of the above technical solution: the second cutting area includes a second support plate, which is installed on the upper surface of the work frame, and an active roller and a cutting roller are installed between the two second support plates.
[0009] As a further description of the above technical solution: the third cutting area includes a support plate three, which is installed on the upper surface of the work frame, and an active roller three and a cutting roller three are installed between the two support plates three.
[0010] As a further description of the above technical solution: a motor is installed on the upper surface of the support frame, a belt is installed between the output end of the motor and the active roller three, a belt is installed between the active roller three and the active roller two, and a belt is installed between the active roller two and the active roller one.
[0011] As a further description of the above technical solution: Cutting roller one, cutting roller two and cutting roller three are mounted on their outer surfaces, and cutting tools one, two and three are mounted on their outer surfaces, and the cutting positions of the outer surfaces of cutting tools one, two and three are not the same.
[0012] As a further description of the above technical solution: the impurity removal mechanism includes an auxiliary plate, which is installed on the upper surface of the support frame away from the support plate three. A motor two is installed on the outer surface of the auxiliary plate, and an impurity removal roller is installed at the output end of the motor two. An impurity removal rod is installed on the outer surface of the impurity removal roller. A working plate is installed between the two auxiliary plates, and a collection box is installed inside the support frame.
[0013] As a further description of the above technical solution: the position and number of the impurity removal rods are consistent with the cutting positions on the outer surfaces of the cutting roller one, cutting roller two and cutting roller three.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by setting multiple cutting zones and cutting tools at different cutting positions, heavy-duty cardboard box raw materials pass through the first, second, and third cutting zones in sequence. The first, second, and third cutting tools cut the cardboard box at different positions and with different functions. The cutting positions of the cutting tools in each cutting zone are different, which disperses the load on the cutting tools and avoids excessive wear at a single cutting position. This effectively solves the problem of decreased accuracy caused by frequent use of a certain cutting position of traditional cutting tools, extends the overall tool life, reduces the frequency of downtime for tool replacement, and lowers production costs.
[0016] 2. In this utility model, the impurity removal mechanism is driven by a motor to rotate the impurity removal roller. The impurity removal rod on the outer surface of the impurity removal roller is precisely matched according to the cutting position of the cutting roller, which can scrape off the waste generated by each cutting. After the waste is peeled off, it falls onto the surface of the working plate and slides into the collection box for centralized processing, avoiding the accumulation of waste that could cause the equipment to jam, ensuring the normal operation of the equipment, improving the cleanliness of the working environment, and reducing the difficulty and time of subsequent cleaning work.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-3 An embodiment of this utility model is provided: a continuous die-cutting machine for heavy-duty carton production, including a support frame 1, a working frame 2 installed inside the support frame 1, a control box 3 installed outside the support frame 1, a cutting mechanism 4 installed inside the working frame 2, and a cleaning mechanism 5 installed inside the working frame 2.
[0024] The cutting mechanism 4 consists of a first cutting area 41, a second cutting area 42 and a third cutting area 43. The first cutting area 41 includes a support plate 411, which is installed on the upper surface of the work frame 2. An active roller 412 and a cutting roller 413 are installed between the two support plates 411.
[0025] The second cutting zone 42 includes a second support plate 421, which is installed on the upper surface of the work frame 2. An active roller 422 and a cutting roller 423 are installed between the two support plates 421.
[0026] The third cutting zone 43 includes a support plate 3 431, which is installed on the upper surface of the work frame 2. An active roller 3 432 and a cutting roller 3 433 are installed between the two support plates 3 431.
[0027] Specifically, support plate 1 411, support plate 2 421, and support plate 3 431 are used to provide the installation position. Drive roller 1 412, cutting roller 1 413, drive roller 2 422, cutting roller 2 423, drive roller 3 432, and cutting roller 3 433 are used to transport and cut the cardboard box raw materials.
[0028] A motor 6 is mounted on the upper surface of the support frame 1. A belt 7 is installed between the output end of the motor 6 and the drive roller 432. A belt 8 is installed between the drive roller 432 and the drive roller 422. A belt 9 is installed between the drive roller 422 and the drive roller 412.
[0029] Specifically, motor 6 serves as the power source. Belts 7, 8, and 9 are used to transmit power.
[0030] Cutting roller 1 413, cutting roller 2 423 and cutting roller 3 433 are equipped with cutting tools 1 10, 11 and 12 on their outer surfaces. The cutting positions on the outer surfaces of cutting tools 1 10, 11 and 12 are not the same.
[0031] Specifically, avoid excessive wear at a single cutting point.
[0032] The impurity removal mechanism 5 includes an auxiliary plate 501, which is installed on the upper surface of the support frame 1 away from the support plate 431. A motor 502 is installed on the outer surface of the auxiliary plate 501. An impurity removal roller 503 is installed at the output end of the motor 502. An impurity removal rod 504 is installed on the outer surface of the impurity removal roller 503. A working plate 505 is installed between the two auxiliary plates 501. A collection box 506 is installed inside the support frame 1.
[0033] Specifically, auxiliary plate 501 provides necessary support for the cardboard box raw materials. Motor 502 serves as the power source. Removal roller 503 and removal rod 504 are used to remove waste materials. Collection box 506 is used to recycle waste materials.
[0034] The position and number of the impurity removal rods 504 are consistent with the cutting positions on the outer surfaces of cutting roller 1 413, cutting roller 2 423 and cutting roller 3 433.
[0035] Specifically, it enables precise removal of adhering waste materials.
[0036] Working Principle: After the equipment is started, the operator sets the die-cutting parameters through the control box 3. Motor 6 drives the active rollers 432, 422, and 412 to rotate synchronously via belts 7, 8, and 9, which in turn drive the cutting rollers 413, 423, and 433 in each cutting zone to operate at the set speed. Heavy-duty cardboard material is fed into the first cutting zone 41 from the feed end and guided by the support plate 411 into the gap between the active roller 412 and the cutting roller 413. At this time, the cutter 10 mounted on the outer surface of the cutting roller 413 performs the first die-cutting process on the cardboard under high-speed rotation. The cutting position of the cutter 10 is designed according to the preset shape to complete the initial grooving or creasing. Subsequently, the cardboard material is transported to the second cutting zone 42 via the belt drive system, where the cutter 11 on the cutting roller 423 performs secondary cutting at different positions, such as edge trimming or punching. Because the cutting position of tool 2 11 is different from that of tool 10, the tool load can be effectively distributed, avoiding excessive wear in a single area. Next, the material enters the third cutting zone 43, where tool 3 12 outside the cutting roller 3 433 performs the final precision cut. The stepped design of the three cutting zones not only realizes continuous die cutting, but also extends the overall tool life and reduces the frequency of downtime for tool replacement through differentiated tool configuration.
[0037] During the die-cutting process, waste materials such as paper scraps or edge pieces generated by the friction between the cutting rollers and the cardboard box will adhere to the material surface or be scattered inside the work frame 2. At this time, the impurity removal mechanism 5 is activated simultaneously: motor 2 502 drives the impurity removal roller 503 to rotate, and the impurity removal rod 504 installed on its outer surface is precisely matched according to the cutting positions of cutting roller 1 413, cutting roller 2 423 and cutting roller 3 433, ensuring that the waste generated from each cut can be scraped off by the corresponding impurity removal rod 504. After the waste is stripped off by the rotation of the impurity removal rod 504, it falls onto the surface of the work plate 505 and slides at an inclined angle into the collection box 506 at the bottom of the support frame 1 for centralized processing. This design not only avoids equipment jamming caused by waste accumulation, but also improves the cleanliness of the working environment.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
