[0027] The technical solution of the utility model provides a sheet material die cutting machine.

[0028] Reference Figures 1 to 5 , in this embodiment, includes:

[0029] The housing 1 comprises a front housing 11 and a rear housing 12. The front housing 11 is provided with a feed inlet 111, and the rear housing 12 is provided with a discharge port 121, and the feed inlet 111 and the discharge port 121 are at the same horizontal position;

[0030] The roller 22 assembly is arranged in the shell 1, and the roller 22 assembly includes a mounting frame 21, a roller 22 and a driving assembly 23. The mounting frame 21 is connected to the inner wall of the shell 1, and the roller 22 and the driving assembly 23 are both connected to the mounting frame 21. The roller 22 is provided with two groups, and the two groups of rollers 22 are arranged in parallel up and down; along the middle of the roller 22 extending to both ends, the diameter of the roller 22 gradually decreases; the driving assembly 23 is drivingly connected to the roller 22 to drive the roller 22 to rotate.

[0031] Optionally, in this embodiment, the shell 1 includes a front shell 11 and a rear shell 12, the front shell 11 is provided with a feed port 111, and the rear shell 12 is provided with a discharge port 121, so that the material enters from the feed port 111 and flows out from the discharge port 121, and the feed port 111 is arranged relative to the discharge port 121, and the size, dimension and horizontal height of the feed port 111 are the same as those of the discharge port 121, ensuring that the material is convenient to enter and exit and convenient to process; the roller 22 assembly is arranged in the shell 1, including a mounting frame 21, a roller 22 and a driving assembly 23, the mounting frame 21 is connected to the inner wall of the shell 1, wherein the roller 22 and the driving assembly 23 are both connected to the mounting frame 21, and the mounting frame 21 is arranged to complete the fixation of the roller 22 and the driving assembly 23 to prevent displacement when the sheet is die-cut. The rollers 22 are arranged in two groups, and the two groups of rollers 22 are arranged in parallel up and down. The diameter of the rollers 22 gradually decreases along the direction extending from the middle of the rollers 22 to the two ends. That is, the rollers 22 are narrow at both ends and wide in the middle, so that the die-cutting space formed by the two groups of rollers 22 is wide at both ends and narrow in the middle. Compared with the rollers 22 in the prior art, which have the same diameter at both ends and the middle, the rollers 22 with narrow ends and wide middle form a die-cutting space with wide ends and narrow middle, which can complete the die-cutting of the sheet and prevent the die-cutting of the middle part of the sheet from being inadequate, resulting in unqualified products. The die-cutting space in the prior art has the same width at both ends and in the middle, resulting in the middle part of the sheet not being inadequately die-cut, resulting in incomplete die-cutting or failure to achieve die-cutting, resulting in unqualified product production. The driving assembly 23 is drivingly connected to the roller 22 to drive the roller 22 to rotate, and the two groups of rollers 22 rotate in opposite directions, so that the sheet material can enter the feed port 111 and move to the discharge port 121 for die cutting.

[0034] In this embodiment, the driving assembly 23 includes a driving motor 231, a gear 232, a fixing frame 233 and a bearing 234, wherein the bearing 234 is rotatably connected to the fixing frame 233, the output end of the driving motor 231 is connected to the gear 232, one end of the gear 232 is connected to the bearing 234, and the other end is connected to the roller 22, the gear 232 and the driving motor 231 are fixedly placed by the fixing frame 233, the gear 232 and the driving motor 231 are each provided with two groups, which are respectively connected to the upper and lower groups of rollers 22, the two groups of driving motors 231 rotate in opposite directions, driving the two groups of gears 232 to rotate in opposite directions, so that the rotation directions of the two groups of rollers 22 are opposite, and the sheet material entering from the feed port 111 can be moved toward the discharge port 121, completing the transportation and die-cutting of the sheet material. Furthermore, the drive assembly 23 also includes a gear sleeve 235, which is sleeved on the output shaft of the gear 232. The sleeve can support the additional weight between the shaft and the bearing 234 to ensure the stable operation of the gear 232 shaft, making the entire mechanical equipment more stable and reliable; the sleeve plays a role in protecting the gear 232 shaft to prevent it from unnecessary external damage.

[0035] In this embodiment, the mounting frame 21 is detachably connected to the inner wall of the shell 1, and the roller 22 is detachably connected to the mounting frame 21. During the production process, the required die-cutting space size varies depending on the die-cutting material. The mounting frame 21 is detachably connected to the inner wall of the shell 1, and the roller 22 is detachably connected to the mounting frame 21. This facilitates the replacement of the roller 22 model and adjusts the die-cutting space to adapt to different sheets. This allows for flexible production of a variety of sheets with high production efficiency.
