Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard box processing equipment. Specifically, it relates to a new type of slotting transverse pressing knife roller that integrates transverse pressing and slotting functions, which is suitable for continuous, high-precision slotting and pressing of corrugated cardboard. Background Technology

[0002] In the corrugated cardboard box production process, slotting and transverse crease marking are the core processes for preparing the box body: slotting is used to form the splicing grooves of the box body, and transverse crease marking is used to determine the folding edges of the box (such as the creases on the lid and bottom). The current mainstream equipment in the industry has the following technical solutions and shortcomings: The dual-roller step-by-step processing scheme adopts a "crease roller + slotting roller" dual-roller structure. First, an independent crease roller creases the cardboard laterally, and then the slotting roller completes the slotting by secondary positioning. In this scheme, each rotation of the cutter shaft corresponds to processing one cardboard sheet. When processing small-sized cardboard (such as cartons with a side length <200mm), the cardboard feed gap accounts for more than 35%, resulting in a long idle run time for the equipment. In addition, the cutter head diameter is fixed (usually φ300-φ500mm), which limits the adjustment range of the gap between the two slots (i.e., the box height). When the box height difference is >100mm, different cutter heads or the entire machine need to be replaced, resulting in poor versatility.

[0003] Single-roller single-function solution: Some high-end equipment adopts an independent cutter shaft design, with a sliding cutter seat installed on the lower cutter roller, but it only supports a single function (only pressing or only grooving). The process needs to be completed by multiple sets of cutter shafts working together. Each set of cutter shafts needs to be driven by an independent servo motor (power ≥ 2kW), and the total power of the equipment reaches 8-12kW, resulting in high energy consumption. Moreover, multi-axis installation requires additional space (the width of the equipment increases by 1.2-1.5m), resulting in low factory utilization.

[0004] To address this issue, a novel slotted transverse pressure roller is proposed. Summary of the Invention

[0005] In view of this, the present invention provides a novel slotted transverse pressing roller, which aims to solve the problems of long idle running time, poor equipment versatility, high energy consumption and low space utilization caused by process separation in the existing equipment described in the background art.

[0006] This utility model is achieved through the following technical solution: A novel slotting transverse pressure cutter roller includes a cutter roller, a transverse pressure strip, a slotting cutter, a guide rail, and a cover plate. The cutter roller has a hollow structure with air inlets and outlets, allowing for continuous air blowing to the processing area via an external air source, effectively preventing paper scrap accumulation and ensuring processing quality and cutter life. The transverse pressure strip is fixedly installed at the center of the cutter roller surface for transverse crease pressing of corrugated cardboard. The slotting cutter is slidably mounted on the cutter roller via the guide rail, allowing for flexible adjustment of the slotting position according to different carton sizes, significantly improving equipment versatility and production efficiency.

[0007] Furthermore, the grooving cutter includes a cutter head seat, a cross-cutting cutter seat, a cross-cutting cutter, and a corner cutter. The cross-cutting cutter is fastened to the cross-cutting cutter seat by a pressure strip, and the corner cutter is installed by a special pressure block. Both support quick disassembly and replacement, greatly facilitating maintenance and cutter adjustment, and reducing downtime.

[0008] Furthermore, the grooving cutter of this utility model is provided in two sets and can move independently along the axial direction of the cutter shaft roller to meet the processing requirements of different box widths and groove spacings, and is particularly suitable for small and medium batch production and multi-specification order production.

[0009] Furthermore, the grooving knife preferably includes at least one straight grooving knife and at least one corner knife, which can respectively complete the straight grooving of the cardboard and the corner clearing, with high functional integration and multiple uses in one machine.

[0010] Furthermore, the corner cutter is mounted on the cross-cutting cutter holder via a pressure block. This pressure block structure not only ensures that the corner cutter is firmly installed, but also facilitates quick replacement on-site, adapting to different groove depths and angle requirements.

[0011] Furthermore, pressure strips are provided on both sides of the cross-cutting blade to reliably fix the cross-cutting blade to the cross-cutting blade holder, preventing displacement during processing and ensuring grooving accuracy.

[0012] Furthermore, in a preferred embodiment of this utility model, four sets of cross-cutting blade holders are provided, each set of blade holders is equipped with a cross-cutting blade and a corner blade, and is connected and fixed by a blade disc holder. The structure is compact and reasonable, with good rigidity, and is suitable for high-speed continuous production.

[0013] Furthermore, the cover plate is located below the cross-cutting blade and has an exhaust hole. This exhaust hole is located between the two serrated blades of the cross-cutting blade, and the airflow can accurately blow out the paper scraps in the groove to avoid blockage and dust accumulation.

[0014] Furthermore, the two ends of the transverse pressure strip are embedded between the two serrated blades at the end of the transverse cutter, achieving seamless axial connection between the crease and slotting processes, reducing the number of cardboard positioning operations, and improving processing accuracy and efficiency.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By integrating the horizontal pressure strip and multiple sets of grooving knives onto the same cutter shaft roller, multiple processes such as pressing lines, grooving, and corner clearing can be completed in one go, reducing equipment idle running and improving production efficiency; The grooving cutter can be flexibly adjusted along the guide rail, and can adapt to different box heights and groove spacings without changing the cutter head. The equipment is highly versatile, reducing changeover time and costs. The air-blowing cleaning structure, combined with the special exhaust hole design of the cover plate, effectively removes paper scraps, ensuring processing quality and long-term stable operation of the equipment; The corner cutter and cross cutter adopt a modular quick-change design, which makes maintenance convenient and reduces downtime. The overall structure is compact and the functions are highly integrated, reducing transmission components and independent drive units, which significantly reduces equipment energy consumption and floor space.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, 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.

[0021] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figures 1-9 As shown, the novel slotting transverse pressing roller provided by this utility model is mainly used for slotting and transverse pressing of corrugated cardboard, and is especially suitable for occasions in the carton manufacturing industry where continuous, efficient and high-precision slotting and pressing of cardboard is required.

[0023] This invention integrates the horizontal pressure strip and multiple sets of grooving knives onto the same cutter roller, enabling multiple processes such as pressing, grooving, and corner clearing to be completed simultaneously in a single feed, significantly improving production efficiency and processing accuracy while reducing equipment energy consumption and floor space.

[0024] like Figure 3 , 4 As shown in Figure 5, this novel grooving transverse pressure cutter roller includes core components such as a cutter roller 1, transverse pressure strips 2, grooving cutters 3, guide rails 4, and a cover plate 5. The cutter roller 1 is a hollow cylindrical structure made of high-quality steel, possessing high rigidity and wear resistance. An air inlet 11 is provided at the end of the cutter roller 1, allowing for continuous air blowing to clean the processing area via an external air source. This air blowing system effectively prevents paper scraps from accumulating in the cutter groove, ensuring grooving quality and extending the tool's service life.

[0025] The transverse pressure strip 2 is fixedly installed at the center of the outer surface of the cutter roller 1. It is made of high-strength alloy material and is firmly connected to the cutter roller 1 by bolts or welding. The transverse pressure strip 2 is used to crease the corrugated cardboard laterally. Its crease profile can be designed according to the folding requirements of the carton and has good wear resistance and fatigue resistance. The two ends of the transverse pressure strip 2 extend to the working area of ​​the slotting knife 3 and interlock with the serrated blade at the end of the cross-cutting knife 33 to achieve seamless connection of crease and slotting in the axial direction, avoiding errors caused by multiple positioning of the cardboard.

[0026] The grooving knife 3 is slidably mounted on the knife shaft roller 1 via the guide rail 4, and its axial position can be flexibly adjusted according to the size of the carton. The grooving knife 3 includes a knife disc holder 31, a cross-cutting knife holder 32, a cross-cutting knife 33, and a corner knife 34. The knife disc holder 31 is an integral or split structure used to fix multiple sets of cross-cutting knife holders 32. The cross-cutting knife holders 32 are connected to the knife shaft roller 1 via the guide rail 4, and can move axially and be locked in position.

[0027] The cross-cutting blade 33 is mounted on the cross-cutting blade holder 32 and consists of two parallel serrated blades used for straight groove cutting of cardboard. Pressure strips 331 are provided on both sides of the cross-cutting blade 33, which are fastened with bolts to prevent displacement of the blade during high-speed cutting and ensure grooving accuracy.

[0028] The corner cutter 34 is mounted on the cross-cutting blade holder 32 via a dedicated pressure block 341 and is used for corner cleaning of cardboard. The pressure block 341 is designed with a quick-release structure, which facilitates on-site replacement of the corner cutter 34 and adapts to different groove depths and corner shapes.

[0029] In this invention, two sets of grooving cutters 3 are preferably provided, located on the left and right sides of the cutter shaft roller 1, respectively, and can move independently along the axial direction to meet the processing requirements of different box widths and groove spacings. Each set of grooving cutters 3 includes four sets of cross-cutting cutter holders 32, and each set of cutter holders is equipped with a cross-cutting cutter 33 and a corner cutter 34, which are connected and fixed by a cutter disc holder 31 to form a rigid integral structure suitable for high-speed continuous production.

[0030] like Figure 9 As shown, the cover plate 5 is located below the cross-cutting blade 33 and is fixed to the cutter shaft roller 1 by bolts. It is used to seal the internal structure of the cutter shaft roller 1 and guide airflow. The cover plate 5 is provided with an exhaust hole 51, which is located between the two serrated blades of the cross-cutting blade 33. The blowing airflow can accurately blow out paper scraps in the groove, avoiding blockage and dust accumulation, and further ensuring processing quality.

[0031] In practical applications, the cutter roller 1 is mounted on the main frame of the slotting machine and is driven to rotate by a servo motor. The cardboard is continuously fed between the cutter roller 1 and the bottom roller by the feeding mechanism. As the cutter roller 1 rotates, the transverse pressure strip 2 first performs transverse creases on the cardboard, and then the slotting blade 3 completes the cutting of straight and corner slots. The air blowing system operates continuously, introducing compressed air through the air inlet 11. The airflow passes through the internal cavity of the cutter roller 1 and is ejected from the air outlet 12 and the exhaust port 51 of the cover plate 5, promptly removing paper scraps generated during the cutting process.

[0032] This device is particularly suitable for small to medium batch production of multi-specification orders. By simply adjusting the axial position of the slotting knife 3, it can adapt to the processing of cardboard with different box heights and slot spacings without the need to replace the cutter head or the whole machine, which significantly improves the versatility of the equipment and reduces changeover time and costs.

[0033] In addition, all cutting tools adopt a modular quick-change design, which makes maintenance convenient, reduces downtime, has a compact overall structure, highly integrates functions, reduces transmission components and independent drive units, and significantly reduces equipment energy consumption and floor space.

[0034] In summary, this utility model, through its integrated structural design, enables the simultaneous completion of the slotting and transverse pressing processes of corrugated cardboard, effectively solving the problems of long idle running time, large positioning errors, high energy consumption, and large footprint caused by process separation in the prior art. It has significant technological progress and practical value.
