Description

Technical Field

[0001] This application relates to the field of cutting device technology, and in particular to an adjustable blade slitting device. Background Technology

[0002] In modern industrial production, especially in many fields such as packaging, printing, leather products, and electronic materials processing, the material slitting process is a crucial step. With the rapid growth of product diversification and customization demands, the requirements for the flexibility, precision, and adaptability of slitting equipment are becoming increasingly stringent.

[0003] Traditional slitting machines mostly use a fixed die structure. The spacing and relative position of the dies are basically fixed after the equipment is installed and debugged, making it difficult to make quick adjustments according to different product specifications and processing requirements during production. For example, in the packaging industry, it is often necessary to produce packaging boxes of various sizes according to different customer orders, from large gift boxes to small and exquisite cosmetic boxes, with huge differences in the required slitting width. If a traditional slitting machine is used, the machine must be stopped whenever the product specifications change, consuming a lot of manpower and time to manually replace the dies or perform complex mechanical adjustments to the entire machine. This not only seriously affects production efficiency and leads to longer order delivery cycles, but also causes die wear and reduced equipment precision due to frequent disassembly and assembly. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an adjustable blade slitting device that can improve production efficiency and versatility.

[0005] This application provides an adjustable blade slitting device, comprising:

[0006] frame;

[0007] The distance adjustment mechanism includes a connecting frame, a first drive structure, a second drive structure, and a mounting frame. The two ends of the connecting frame are respectively disposed on both sides of the frame. The first drive structure includes a first fixing part and a first drive end. The first fixing part is disposed on the top of the connecting frame, and the first drive end passes through the connecting frame and is connected to the mounting frame. The mounting frame is located inside the connecting frame. The second drive structure includes a second fixing part and a plurality of second drive ends.

[0009] The main control module is connected to the first driving structure and the second driving structure respectively, and is used to drive the first driving end to move in the vertical direction and to drive a plurality of the second driving ends to move in the horizontal direction respectively.

[0010] The adjustable cutting tool device according to the embodiments of this application has at least the following beneficial effects: When the device starts the adjustment program, the main control module first sends a signal to the first drive structure, causing its first drive end to retract vertically upwards, smoothly raising the mounting frame and the cutting die assembly to a high position, making room for subsequent adjustments and preventing interference. Next, the main control module drives the second drive structure according to the product size data. The second fixing part is fixed to the mounting frame, and multiple second drive ends synchronously extend and retract horizontally via internal transmission, precisely adjusting the spacing between the cutting die assemblies. After the spacing is adjusted, the main control module again commands the first drive structure, causing the first drive end to extend downwards in the opposite direction, pressing the cutting die assembly down until it is in close contact with the workpiece to be cut, achieving a suitable cutting pressure. Then, the cutting die cuts the workpiece according to the set parameters. In the solution of this application, the spacing between the die-cutting components can be adjusted without disassembling and reassembling the die-cutting components.

[0032] In modern industrial production, especially in many fields such as packaging, printing, leather products, and electronic materials processing, the material slitting process is a crucial step. With the rapid growth of product diversification and customization demands, the requirements for the flexibility, precision, and adaptability of slitting equipment are becoming increasingly stringent.

[0033] Traditional slitting machines mostly use a fixed die structure. The spacing and relative position of the dies are basically fixed after the equipment is installed and debugged, making it difficult to make quick adjustments according to different product specifications and processing requirements during production. For example, in the packaging industry, it is often necessary to produce packaging boxes of various sizes according to different customer orders, from large gift boxes to small and exquisite cosmetic boxes, with huge differences in the required slitting width. If a traditional slitting machine is used, the machine must be stopped whenever the product specifications change, consuming a lot of manpower and time to manually replace the dies or perform complex mechanical adjustments to the entire machine. This not only seriously affects production efficiency and leads to longer order delivery cycles, but also causes die wear and reduced equipment precision due to frequent disassembly and assembly.

[0034] Based on this, this application provides an adjustable blade slitting device to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0035] Reference Figure 1 and Figure 2 This application provides an adjustable cutting tool device, including: a frame, an adjustment mechanism, a die assembly, and a main control module; the adjustment mechanism includes a connecting frame, a first drive structure, a second drive structure, and a mounting frame, with both ends of the connecting frame respectively disposed on both sides of the frame; the first drive structure includes a first fixing part and a first drive end, the first fixing part being disposed on the top of the connecting frame, and the first drive end passing through the connecting frame and connected to the mounting frame, the mounting frame being located inside the connecting frame; the second drive structure includes a second fixing part and a plurality of second drive ends, the second fixing part being disposed on the mounting frame; the number of die assemblies corresponds to the number of second drive ends, with each die assembly corresponding to a second drive end; the main control module is connected to the first drive structure and the second drive structure respectively, for driving the first drive end to move in the vertical direction, and driving the plurality of second drive ends to move in the horizontal direction respectively.

[0036] When the equipment starts the adjustment program, the main control module first sends a signal to the first drive structure, causing its first drive end to retract vertically upwards, smoothly raising the mounting frame and die assembly to a high position, making room for subsequent adjustments and preventing interference. Next, the main control module drives the second drive structure according to the product size data. The second fixing part is fixed to the mounting frame, and multiple second drive ends synchronously extend and retract horizontally via internal transmission, precisely adjusting the spacing between the die assemblies. After the spacing is adjusted, the main control module again commands the first drive structure, causing the first drive end to extend downwards in the opposite direction, pressing the die assembly down until it is in close contact with the workpiece to be cut, achieving the appropriate cutting pressure. The die then cuts the workpiece according to the set parameters. In the solution of this application, the spacing adjustment between the die assemblies does not require disassembly and reassembly. The spacing adjustment can be completed by moving the second drive end, reducing labor costs and labor intensity, improving convenience and production efficiency. At the same time, the flexible adjustment function adapts to various products, improving the versatility of the adjustable die cutting device provided in this application.

[0037] Reference Figure 1 It is understandable that the spacing adjustment mechanism also includes guide columns, with at least two guide columns. The two ends of each guide column are connected to the connecting frame and the mounting bracket, respectively, and the at least two guide columns are located on both sides of the first drive structure. The guide columns provide a precise path for the vertical lifting and lowering of the mounting bracket. When the first drive end extends or retracts, the mounting bracket will not experience any abnormal displacement such as offset or torsion, maintaining an ideal coordinated motion state with the first drive structure at all times, enabling the die-cutting assembly to accurately align with the workpiece. Moreover, during frequent die-cutting spacing adjustments, the guide columns continuously maintain this smooth and stable guiding performance, reducing frictional wear between mechanical parts, extending the service life of critical equipment structures, and lowering equipment maintenance frequency and costs.

[0038] Reference Figure 1 and Figure 3 It is understandable that the mounting frame is equipped with a guide structure, the guiding direction of which is the same as the moving direction of the second drive end, and multiple die-cutting assemblies are connected to the guide structure respectively. By providing a guide structure on the mounting frame, and ensuring that the guiding direction of the guide structure is precisely consistent with the moving direction of the second drive end, the die-cutting assemblies, under the push of the second drive end, can only move linearly in a preset horizontal direction, thus improving the stability of the die-cutting assembly's movement.

[0039] Continue to refer to Figure 1 and Figure 3It is understood that the guide structure includes a slide rail and several sliders, the number of which corresponds to the number of die-cutting assemblies. The slide rail is mounted on the mounting bracket, and its length direction is the same as the movement direction of the second drive end. Each die-cutting assembly is mounted on the slide rail via its corresponding slider. Since the slide rail's length direction is the same as the movement direction of the second drive end, when the second drive end pushes the die-cutting assembly, the sliders move smoothly along the slide rail, strictly limiting the movement path of the die-cutting assembly and ensuring accurate horizontal displacement. The combination of the slide rail and sliders provides precise guidance for the die-cutting assembly, making its movement smoother and improving its stability.

[0040] Reference Figure 1 and Figure 2 Understandably, several slide rails are provided, spaced apart on the mounting frame. Several sliders are evenly distributed on these slide rails. The die-cutting assembly is connected to one of the slide rails via a slider, and adjacent die-cutting assemblies are connected to different slide rails via their sliders. The multiple spaced slide rails allow the weight of the die-cutting assembly and the reaction force it experiences during the cutting process to be more evenly distributed on the mounting frame. This reduces the risk of deformation or damage to specific parts of the mounting frame due to long-term pressure, enhancing the stability and durability of the entire mounting frame structure.

[0041] Reference Figure 1 and Figure 4 It is understandable that the adjustment mechanism also includes two fine-tuning structures. These structures are located at both ends of the connecting frame and connected to both ends of the mounting bracket. These fine-tuning structures are used to adjust the height of the corresponding ends of the mounting bracket. In actual operation, even when the mounting bracket is raised and lowered as a whole via the first drive structure, minor errors in the manufacturing and installation of components such as the frame and connecting frame, or uneven wear after long-term use, may cause a slight tilt in the horizontal direction of the mounting bracket and the die assembly. The two fine-tuning structures, located at both ends of the connecting frame and connected to both ends of the mounting bracket, allow for independent height adjustments at both ends of the mounting bracket. This effectively compensates for any deficiencies in overall leveling, ensuring that the mounting bracket and die assembly are perfectly horizontal, thereby improving the cutting accuracy of the product.

[0042] Reference Figure 4It is understood that the connecting frame has openings on both sides. The fine-tuning structure includes an adjusting nut, an adjusting screw, a bushing, and a connecting block. The adjusting nut is located on top of the connecting frame, and the adjusting screw is located inside the opening, with one end passing through the top of the opening and connecting to the adjusting nut, while the other end is rotatably positioned at the bottom of the opening. The bushing has threads on its inner side and is fitted onto and threadedly connected to the adjusting screw. The mounting bracket is connected to the bushing via the connecting block. The adjusting screw and the bushing are connected by threads. When the adjusting nut is rotated, the adjusting screw rotates accordingly. Due to the action of the threads, the bushing moves precisely linearly along the adjusting screw, thereby meeting the high-precision adjustment requirements of the die assembly height and further improving cutting accuracy and product quality.

[0043] Reference Figure 1 and Figure 4 It is understood that the mounting frame includes a horizontal connecting plate, and the first drive end is connected to the horizontal connecting plate. Both ends of the horizontal connecting plate pass through openings on both sides of the connecting frame and are connected to corresponding connecting blocks. The first drive end of the first drive structure is connected to the horizontal connecting plate. When the first drive end moves vertically, it can evenly transmit the driving force to the horizontal connecting plate. Because the horizontal connecting plate has a certain rigidity and area, it can distribute the driving force throughout the entire mounting frame, thus making the die assembly more evenly stressed during lifting and lowering. This avoids deformation of the mounting frame or damage to the die assembly due to excessive local stress, improving the stability and reliability of the device.

[0044] Reference Figure 1 and Figure 2 Understandably, conveyor rollers are also installed between the two sides of the frame, located below the die assembly. These conveyor rollers, positioned below the die assembly, provide stable support and driving force for the material to be cut, enabling it to move continuously and smoothly forward during the cutting process. This ensures the continuity of the cutting operation, preventing interruptions or jams caused by poor material movement, thereby improving production efficiency.

[0045] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
