Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution: an adjustable cutter distance structure for a die-cutting machine, including a worktable body 1 and a cutter body 3. Four opposing support frames 2 are fixedly connected to the top of the worktable body 1. The top of the four support frames 2 are fixedly connected to an upper frame 5. A placement mechanism 4 for limiting the workpiece to be processed is provided at the top of the worktable body 1. An adjustment mechanism 6 for adjusting the distance between the two cutter bodies 3 is provided inside the upper frame 5.

[0017] It should be noted that the four support frames 2 on the main body 1 of the workbench provide stable support for the upper frame 5, ensuring the overall structure is stable and reliable. During the die-cutting process, it can withstand greater pressure and ensure processing accuracy. The placement mechanism 4 is located at the top of the main body 1 of the workbench, which can effectively limit the workpiece to be processed, prevent it from shifting during processing, greatly improve processing quality, and reduce scrap rate. The adjustment mechanism 6 is located inside the upper frame 5, which can flexibly adjust the distance between the two cutting blade bodies 3, so that the die-cutting machine can adapt to the processing needs of different sizes and specifications, greatly expanding the application range of the equipment and improving its versatility and practicality. There is no need to change the cutting blades or equipment; the blade distance can be quickly adjusted simply by adjusting the mechanism 6, saving time and improving production efficiency.

[0018] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, the placement mechanism 4 includes two electric slide rails 45 symmetrically embedded on the top of the workbench body 1. The sliding ends of the two electric slide rails 45 are fixedly connected to the placement platform 41. The placement mechanism 4 is located at the top of the workbench body 1. The four corners of the top of the placement platform 41 are fixedly connected to the first electric push rods 42. The telescopic ends of the four first electric push rods 42 are fixedly connected to the connecting frame 43. The ends of each pair of adjacent connecting frames 43 are fixedly connected to the pressure plate 44 for pressing the workpiece to be processed. The connecting frame 43 and the telescopic ends of the first electric push rods 42 are limited by bolts. The area occupied by the placement platform 41 is half of the top of the workbench body 1.

[0019] It should be noted that two electric slide rails 45 are symmetrically embedded at the top of the worktable body 1, which can drive the placement platform 41 to move smoothly, making it convenient to adjust the position of the workpiece to be processed, meet the needs of different processing stations, and improve processing flexibility. The placement platform 41 occupies half of the top area of ​​the worktable body 1, providing ample and regular placement space for the workpiece to be processed, ensuring that it can be placed stably. The four first electric push rods 42 set at the four corners of the top can precisely control the extension stroke. Through the connecting frame 43 connected to its extension end, the pressure plate 44 is driven down, which can quickly and firmly press the workpiece to be processed, effectively preventing displacement caused by vibration, impact, etc. during processing, and ensuring processing accuracy. The connecting frame 43 and the extension end of the first electric push rod 42 are connected by bolt limit, which not only makes installation and disassembly convenient, but also facilitates maintenance and replacement of parts, and ensures the stability of the connection, ensuring that the pressure plate 44 will not loosen during the pressing process.

[0020] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the adjustment mechanism 6 includes four hydraulic push rods 61 symmetrically embedded in the top of the upper frame 5. The telescopic ends of the four hydraulic push rods 61 are all fixedly connected to the top plate 62. The bottom end of the upper frame 5 has a through groove slightly larger than the outer wall of the top plate 62. The two cutter bodies 3 are located below the top plate 62. A guide groove 621 is provided at the center of the top top of the top plate 62. Through grooves 622 are provided on both sides of the guide groove 621 at the top top of the top plate 62. A second electric push rod 63 is fixedly connected at the center of the top top of the top plate 62. A first blade adjustment frame 64 and a second blade adjustment frame 65 are symmetrically arranged at the top top of the top plate 62, and the first blade adjustment frame 64 and the second blade adjustment frame 65 are both fixedly connected to the two telescopic ends of the second electric push rod 63.

[0021] It should be noted that four hydraulic push rods 61 are symmetrically embedded in the top of the upper frame 5, and can extend and retract synchronously and stably. They provide stable power support for the cutter adjustment through the top plate 62. The top plate 62 extends from the bottom of the upper frame 5 through a through groove, which facilitates the operation of the two cutter bodies 3 below. The guide groove 621 and the through grooves 622 on both sides of the top plate 62 provide precise guidance and movement space for the cutter adjustment, ensuring that the adjustment process is stable and smooth and reducing deviation. The second electric push rod 63 is fixed at the center of the top of the top of the top plate 62. Its two telescopic ends are connected to the first cutter adjustment frame 64 and the second cutter adjustment frame 65 respectively, which can accurately control the movement distance and direction of the two. Driven by the second electric push rod 63, the first cutter adjustment frame 64 and the second cutter adjustment frame 65 can drive the cutter body 3 to move flexibly, quickly and accurately adjust the distance between the two cutter bodies 3, meet the processing needs of different specifications of products, and improve the versatility of the equipment.

[0022] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the first blade holder 64 and the second blade holder 65 are both rotatably connected to the first connecting rod 66 and the second connecting rod 67. At the intersection of each pair of first connecting rods 66 and second connecting rods 67, a limiting pin 68 is rotatably connected for limiting. The lower bottom ends of the first blade holder 64 and the second blade holder 65 are both fixedly connected to the sliders 641. The two sliders 641 are slidably connected to the inside of the guide groove 621. The upper top ends of the two blade bodies 3 are symmetrically fixedly connected to two connecting shafts 31. The four connecting shafts 31 are slidably connected to the inside of the through grooves 622. The upper top ends of the four through grooves 622 are fixedly connected to the lower bottom ends of the first blade holder 64 and the second blade holder 65 through the through grooves 622. The upper top ends of the two limiting pins 68 are both fixedly connected to the guide tubes 69. The upper top end of the second electric push rod 63 is fixedly connected to the guide sleeve 631. The two limiting pins 68 are slidably connected to the inside of the guide tubes 69.

[0023] It should be noted that the first connecting rod 66 and the second connecting rod 67, which are rotatably sleeved within the first and second blade adjusting holders 64 and 65, together with the limiting pin 68, form a stable linkage structure when adjusting the blade spacing. This ensures the accuracy and synchronization of the adjustment action, avoids shaking or deviation during blade adjustment, and improves the precision of blade position adjustment. The slider 641 is slidably sleeved in the guide groove 621, providing precise guidance for the movement of the first and second blade adjusting holders 64 and 65, ensuring that they can only move along the direction of the guide groove 621. This further ensures the straightness and accuracy of blade adjustment. The four connecting shafts 31 are slidably sleeved in the through groove 622, reliably connecting the blade body 3 to the blade adjusting holder. This allows the blade body 3 to move accurately with the movement of the blade adjusting holder, enabling flexible adjustment of the blade spacing. The guide tube 69 and guide sleeve 631 guide and constrain the movement of the limiting pin 68, making the adjustment process smoother and reducing friction and jamming.

[0024] Working principle: When it is necessary to adjust the distance between the two cutter bodies 3, the adjustment mechanism 6 plays a role. The four hydraulic push rods 61 symmetrically embedded in the top of the upper frame 5 first act, and their telescopic ends jointly drive the top plate 62 to move to a suitable height to prepare for subsequent cutter adjustment. Then, the second electric push rod 63 at the center of the top of the top plate 62 is started as a power source. Its two telescopic ends drive the first cutter adjustment frame 64 and the second cutter adjustment frame 65 to move linearly. The first connecting rod 66 and the second connecting rod 67, which are rotatably connected inside the first cutter adjustment frame 64 and the second cutter adjustment frame 65, are limited by the limiting pin 68 at the intersection of the two to ensure that the first cutter adjustment frame 64 and the second cutter adjustment frame 65 move synchronously. Meanwhile, the sliders 641 at the bottom of the first and second tool holders 64 and 65 slide in the guide groove 621 at the top of the top plate 62 to ensure the linearity of the movement. The cutter body 3, which is connected to the first and second tool holders 64 and 65 through the connecting shaft 31, moves in a straight line as the tool holders move. The four connecting shafts 31 slide in the through groove 622 at the top of the top plate 62. In this way, the distance between the two cutter bodies 3 can be adjusted in time according to the user's needs, so as to effectively cut the product to be processed and ensure that each product cut is of the same length. In the top placement mechanism 4 on the main body of the workbench 1, the electric slide rail 45 drives the placement table 41 to move and adjust the position of the workpiece to be processed. The first electric push rod 42 at the top of the placement table 41 drives the pressure plate 44 to press the workpiece to be processed through the connecting frame 43, so as to ensure processing stability.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
