[0024] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0025] like Figure 1-5 As shown, a feeding device for a die-cutting machine comprises a device body 1, a transmission frame 2 is installed inside the device body 1, and the transmission frame 2 is a long ring-shaped mechanism, such as a conveyor belt. A plurality of mounting grooves are arranged on the outer side of the transmission frame 2 for placing workpieces, such as cardboard sheets, etc. The cardboard sheets can be placed in the mounting grooves on the transmission frame 2, and the workpieces can be loaded and transported to the vicinity of the cutting assembly by the oil transmission frame 2. A support plate 3 is fixed on the top of the device body 1 and located on the top of the transmission frame 2, a mounting frame 4 is fixed on one end of the support plate 3, and a driving hydraulic cylinder 5 is rotatably connected to the end of the mounting frame 4 away from the support plate 3, and a flattening block 6 is fixed to the end of the stroke rod of the driving hydraulic cylinder 5 through a fixing block 12;

[0026] Through the above arrangement, when the driving hydraulic cylinder 5 is started, the travel rod of the driving hydraulic cylinder 5 can be moved obliquely downward, and the cardboard or paper can be flattened, so that the cardboard has fewer wrinkles and the like;

[0027] An adjustment component is also installed between the device body 1 and the support plate 3 , and the adjustment component is used to adjust the angle of the driving hydraulic cylinder 5 .

[0028] See attached Figure 2-3 The adjusting assembly includes a mounting plate 7 fixed to the top of the device body 1. The mounting plate 7 is arranged on the device body 1, and the mounting plate 7 is arranged on the outside of the transmission frame 2, so as not to contact the workpiece assembled on the transmission frame 2, so as to avoid affecting the normal transportation of the workpiece. The mounting plate 7 is rotatably connected with a rotating frame 8 near the top of one end of the supporting plate 3. Furthermore, a spring is arranged at the rotation connection between the mounting plate 7 and the rotating frame 8, so as to realize that the rotating frame 8 can have an upward rotation force after compression, thereby reducing the force of resetting the driving hydraulic cylinder 5 and increasing the service life of the driving hydraulic cylinder 5. The driving hydraulic cylinder 5 is rotatably connected to the rotating frame 8. It should be noted that the stroke rod of the driving hydraulic cylinder 5 is rotatably connected to the rotating frame 8;

[0029] Under the setting of the rotating frame 8, the travel rod of the driving hydraulic cylinder 5 is extended, and the overall length of the driving hydraulic cylinder 5 is increased. At this time, under the action of the rotating frame 8, the driving hydraulic cylinder 5 can stably change its angle state, thereby realizing the flattening of the workpiece;

[0030] A fixing plate 9 is fixed to one side of the support plate 3 close to the mounting plate 7, and a pressing plate 10 is fixed to the bottom of the fixing plate 9 away from one end of the support plate 3. The pressing plate 10 is arranged so that the pressing plate 10 can press the paper to avoid displacement of the paper when the flattening block 6 flattens the paper. The fixing plate 9 is also connected to the support plate 3 through a hydraulic mechanism so that the fixing plate 9 can move up and down to press the workpiece. A gasket is fixed to the bottom of the pressing plate 10, and the width of the gasket is greater than the width of the pressing plate 10. Through this arrangement, the pressing plate 10 can press the workpiece more tightly through the arrangement of the gasket.

[0031] See attached Figure 4 and attached Figure 5 The end of the driving hydraulic cylinder 5 is also fixed with a rotating circular column 14, and the outer side of the rotating circular column 14 is rotatably connected with a rotating body 13, and the rotating body 13 can realize an angle of rotation on the outer side of the rotating circular column 14. After many tests, the maximum angle that can be realized can reach 75 degrees. The end of the rotating body 13 away from the driving hydraulic cylinder 5 is fixed with a bonding plate 11, and the end of the bonding plate 11 away from the rotating body 13 is L-shaped, which can specifically make the bonding plate 11 bend upward, thereby ensuring that the bent portion of the bonding plate 11 is located in contact with the workpiece, reducing friction, and rotating the circular A plurality of latch teeth 15 are arranged on the outer side of the column 14, and a latch groove 16 is arranged on the inner side of the rotating body 13 and at a position corresponding to the latch teeth 15. Through the arrangement of the latch teeth 15 and the latch groove 16, the user can swing the rotating body 13 to drive the bonding plate 11 to rotate, and the latch teeth 15 are stuck on the inner side of the latch groove 16, so as to fix the bonding plate 11, so that the flattening block 6 and the bonding plate 11 can both press the workpiece, so as to realize double flattening and pressing of the workpiece with severe bending, and when the flattening block 6 flattens the workpiece, the transmission frame 2 can stop transmission.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
