Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, and in particular to an improved die-cutting device. Background Technology

[0002] Die-cutting machines, also known as cutting machines, die-cutting machines, or CNC punching machines, are mainly used for die-cutting, creasing, and hot stamping operations on non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, mobile phone pads, and other products. They are essential equipment for packaging processing and forming. They use steel blades, metal molds, steel wire, or die-cutting blades to apply pressure to the material, causing cardboard or other materials to be cut into the corresponding shapes.

[0003] Currently, traditional die-cutting devices typically employ a planar die-cutting mechanism. This mechanism relies on a servo motor to control the up-and-down movement of the die-cutting plate to achieve the die-cutting action. However, as the paper thickness increases, the resistance that the die-cutting plate needs to overcome also increases. Furthermore, since the output torque of the servo motor is limited, if the resistance exceeds its load-bearing capacity, the motor may experience idle running, which may prevent the die-cutting plate from reaching the predetermined die-cutting depth. This results in a deviation in the position of the die-cutting plate, causing incomplete cutting of the cutting lines on the paperboard.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

Therefore, they should not be construed as limitations on this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] In one embodiment of this utility model, such as Figure 1-7 As shown, an improved die-cutting apparatus is provided, including a flatbed die-cutting machine, on which a planar die-cutting mechanism is provided. The planar die-cutting mechanism includes a die-cutting mounting frame 10 and a die-cutting drive component 20, a support platform 11, a die-cutting component 30, a feeding component 40, a lifting component 50, and an adjusting component 60, all mounted on the die-cutting mounting frame 10.

[0037] A die-cutting drive unit 20 is located on one side of the die-cutting mounting frame 10. A die-cutting component 30 is located above the support platform 11 and is connected to the die-cutting drive unit 20 for die-cutting paper on the support platform 11. A distance is maintained between the die-cutting component 30 and the support platform 11 to allow paper to pass through. A feeding component 40 is located on one side of the support platform 11 for feeding paper and is situated between the support platform 11 and the die-cutting component 30. A lifting component 50 is located below the support platform 11, with its top end connected to the support platform 11 and connected to the die-cutting drive unit 20, for moving the support platform 11 upwards or downwards. An adjusting component 60 is located on the other side of the die-cutting mounting frame 10, and together with the lifting component 50, is used to adjust the position between the lifting component 50 and the support platform 11.

[0038] By setting up a die-cutting component 30 and a die-cutting drive component 20, the first drive shaft 22 of the die-cutting drive component 20 drives the die-cutting lifting unit in the die-cutting component 30 to move up and down, achieving efficient and precise control of the die-cutting process. Specifically, the first drive shaft 22 drives the first cam 23 to rotate, and the cam connecting block 333 converts the rotational motion of the first cam 23 into the vertical linear movement of the lifting side plate 331, thereby causing the lifting unit to drive the die-cutting plate 32 to rise and fall, realizing the die-cutting of paper. Compared with the traditional servo motor control of the die-cutting plate 32 to move up and down, this mechanical transmission method allows the die-cutting component 30 to move precisely to the predetermined position. Even when the paper is thick, it can ensure that the die-cutting plate 32 has sufficient downward pressure to achieve a complete and clean die-cutting effect, greatly improving the production quality of paper processing.

[0039] As further explained, the planar die-cutting mechanism also includes a blocking component 70, which is located at the front end of the feeding component 40 and connected to the die-cutting drive component 20. The die-cutting drive component 20 drives the blocking component 70 to lift or press down to feed or block the paper. By setting the blocking component 70, the paper to be die-cut is limited, preventing the previous batch of paper from being fed in before it is completely die-cut, which would cause paper die-cutting errors and thus improve the die-cutting effect.

[0040] As further explained, the blocking component 70 includes a blocking shaft 71, a blocking block 72, and a first eccentric unit. The blocking shaft 71 is rotatably mounted on the die-cutting mounting bracket 10. The blocking block 72 is mounted on the blocking shaft 71, and at least one set of blocking blocks 72 is provided. The first eccentric unit is located on one side of the die-cutting mounting bracket 10 and is connected to the blocking shaft 71 and the die-cutting drive component 20. The first eccentric unit includes a first V-shaped rotating block 73 and a second V-shaped rotating block 74 distributed left and right. One end of the first V-shaped rotating block 73 has an outwardly extending extension, and the extension is rotatably connected to the die-cutting drive component 20. The first V-shaped rotating block 73 and the second V-shaped rotating block 74 are connected by a first connecting rod 75. The second V-shaped rotating block 74 is connected to the blocking shaft 71 by a second connecting rod 76. An eccentric wheel structure is formed between the die-cutting drive component 20, the first V-shaped rotating block 73, the second V-shaped rotating block 74, and the first connecting rod 75. When the die-cutting drive component is started, the second connecting rod moves upward or downward under the action of the first V-shaped rotating block 73, the second V-shaped rotating block 74, and the first connecting rod 75, which drives the blocking rotating shaft 71 to rotate, thereby raising or lowering the blocking block 72 and limiting the paper. This prevents the previous batch of paper from being die-cut before it is finished and continues to be fed, which would cause the paper to be die-cut incorrectly and improve the die-cutting effect of the paper.

[0041] As further explained, the system also includes a feeding mechanism 80, which comprises a loading component and a conveying component 82. The loading component includes a loading mounting frame 811, a lifting module 812, and a fixing unit 813 for pressing the paperboard. The lifting module 812 is located inside the loading mounting frame 811, and has a lifting platform 814 for placing the paper inside. The lifting module 812 can be a vertically moving module driven by a motor or a lead screw. The fixing unit 813 is located at the top of the loading mounting frame 811 and above the lifting platform 814.

[0042] The conveying component 82 includes a conveying module, which is a conveyor belt. The conveying module is located on one side of the loading mounting frame 811. A fixing plate 821 extending inwards is provided on the conveying module, and a certain distance is maintained between the fixing plate 821 and the conveying module. Multiple sets of pressure rollers 822 are provided on the fixing plate 821, and the pressure rollers 822 are magnetically connected to the fixing plate 821. The bottom end of the pressure rollers 822 has an arc-shaped portion for pressing the paper.

[0043] By setting up the feeding component and the conveying component 82, the paper is automatically fed, ensuring the stability and positional accuracy of the paper during the feeding process. At the same time, by setting up multiple sets of pressure rollers 822 on one side of the conveying module, the paper is corrected to avoid the phenomenon of paper feeding disorder, which provides a strong guarantee for the subsequent die-cutting work.

[0044] As a further explanation, the material discharge mechanism 90 includes a feeding module 91 and a guiding module 92. The feeding module 91 is located on one side of the output end of the die-cutting mounting frame 10 and is flush with the output end of the die-cutting mounting frame 10. The feeding module 91 is a conveyor belt. The guiding module 92 includes multiple sets of guide rods 921 evenly spaced on the feeding module 91. A guiding channel is formed between two adjacent sets of guide rods 921, and a pressure roller 922 for flattening the paper is provided above the end of the guiding channel. By setting up the guiding module 92, the paper is guided and pressed through multiple sets of guiding channels and their corresponding pressure rollers 922, ensuring that the paper is discharged in an orderly manner during the post-die-cutting conveying process, thus improving the paper conveying efficiency and accuracy.

[0045] As further explained, the die-cutting drive component 20 includes a die-cutting drive motor 21 and a first drive shaft 22. The die-cutting drive motor 21 is located on one side of the die-cutting mounting bracket 10. The first drive shaft 22 is rotatably connected to the die-cutting mounting bracket 10, and both ends of the first drive shaft 22 pass through the die-cutting mounting bracket 10. One end of the first drive shaft 22 is connected to the die-cutting drive motor 21. Through the precise cooperation between the die-cutting drive motor 21 and the first drive shaft 22, the stability and reliability of the die-cutting component 30 during the die-cutting process are ensured, thereby improving die-cutting efficiency and quality.

[0046] As further explained, the die-cutting component 30 includes a die-cutting top plate 31, a die-cutting plate 32, and a die-cutting lifting unit. The die-cutting top plate 31 is located at the top of the die-cutting mounting frame 10, and multiple sets of adjusters for horizontal adjustment are provided inside the die-cutting top plate 31. The die-cutting plate 32 is fixed to the bottom end of the die-cutting top plate 31, and the top surface of the die-cutting top plate 31 abuts against the bottom surface of the adjusters. The die-cutting plate 32 is located above the support platform 11. The die-cutting lifting unit includes a lifting side plate 331 and a lifting connecting plate 332. The lifting side plate 331 is located outside the die-cutting mounting frame 10 and is fixedly connected to the side of the die-cutting plate 32. A first cam 23 is provided between the lifting side plate 331 and the first drive shaft 22. A cam connecting block 333 is provided between the first cam 23 and the lifting side plate 331. One end of the lifting side plate 331 and the cam connecting block 333 are connected by the lifting connecting plate 332. The other end of the first cam 23 and the cam connecting block 333 are connected by a cam fixing block. The cam structure formed by the first cam 23, the cam connecting block 333, and the lifting connecting plate 332 converts the rotational motion of the first drive shaft 22 into the vertical linear movement of the lifting side plate 331, thereby enabling the lifting unit to drive the die-cutting plate 32 to rise and fall, thus achieving paper die-cutting. Compared with the traditional servo motor control of the die-cutting plate 32 to move up and down, this mechanical transmission method enables the die-cutting component 30 to move precisely to the predetermined position. Even when the paper is thick, it can ensure that the die-cutting plate 32 has sufficient downward pressure to achieve a complete and clean die-cutting effect, which greatly improves the production quality of paper processing.

[0047] As further explained, the lifting component 50 includes a main offset wheel 51, a secondary offset wheel 52, and a lifting connecting plate 53. The main offset wheel 51 is located at the center of the first drive shaft 22 and within the die-cutting mounting frame 10. The secondary offset wheel 52 is rotatably connected to the die-cutting mounting frame 10 via a second drive shaft 54 ​​and is located below the main offset wheel 51. One protruding end of the secondary offset wheel 52 is connected to the protruding end of the main offset wheel 51. One end of the lifting connecting plate 53 is connected to the protruding end of the secondary offset wheel 52, and the other end is connected to the support platform 11. The first drive shaft 22 drives the main offset wheel 51 to rotate, and the main offset wheel 51 drives the secondary offset wheel 52 to rotate. The secondary offset wheel 52 then drives the support platform 11 to move up and down via the lifting connecting plate 53, thereby changing the vertical height of the support platform 11 to complete the cutting of the cardboard.

[0048] As further explained, the adjusting component 60 includes a turbine 61, a worm gear 62, and an adjusting mounting plate 63. The turbine 61 is located on one side of the die-cutting mounting bracket 10 and connected to one end of the second drive shaft 54. The adjusting mounting plate 63 is located outside the turbine 61, and the turbine 61 is enclosed within the adjusting mounting plate 63. The worm gear 62 passes through the adjusting mounting plate 63 and is located below the turbine 61. The worm gear 62 is meshed with the turbine 61. By rotating the adjusting worm gear 62, the user causes the worm wheel to rotate, thereby changing the position of the secondary offset wheel 52 via the second drive shaft 54, and ultimately changing the height of the support platform 11.

[0049] As further explained, the feeding component 40 includes a conveyor drive motor 41 and a first conveying unit 42 and a second conveying unit 43, which are vertically distributed inside the lifting side plate 331. The conveyor drive motor 41 is located on the outside of the lifting side plate 331, and its output end is connected to the first conveying unit 42. A driven wheel is provided on the outside of the output end of the conveyor drive motor 41. The driven wheel is connected to the second conveying unit 43. In this embodiment, the first conveying unit 42 and the second conveying unit 43 have the same structure, both consisting of two sets of transmission wheels connected by belts, and the two sets of transmission wheels are symmetrically distributed at both ends of the lifting side plate 331. When the conveyor drive motor 41 is started, it drives the first conveying unit 42 to operate, and the driven wheel drives the second conveying unit 43 to operate. The conveyor drive motor 41 drives the driven wheel to rotate synchronously, that is, the first conveying unit 42 and the second conveying unit 43 operate synchronously, thereby realizing the conveying of paper from front to back.
