[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a die-cutting device for processing hat brims, such as... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the die-cutting device for processing the brim includes a base plate 1, a die-cutting frame 2 fixedly installed on the base plate 1, a top frame 3 fixedly installed on the die-cutting frame 2, a conveyor belt 4 set on the die-cutting frame 2, an upper die 5 set on the die-cutting frame 2, a lower die 18 set at the bottom of the die-cutting frame 2, and a pressing mechanism set on one side of the upper die 5 for fixing the material sheet.

[0027] The pressing mechanism includes a hinge seat 6 fixedly installed on one side of the upper mold 5, a pressure rod 7 rotatably installed on the hinge seat 6, a pressure roller 8 rotatably installed on the pressure rod 7, and a tension spring 9 disposed on one side of the upper mold 5. One end of the tension spring 9 is fixedly connected to one side of the upper mold 5, and the other end of the tension spring 9 is fixedly connected to one side of the pressure rod 7.

[0028] When using the die-cutting device for brim processing, first place the base plate 1 in a suitable position, place the material sheet on top of the conveyor belt 4, start the external motor to drive the conveyor belt 4 to rotate synchronously, and the rotation of the conveyor belt 4 will drive the material sheet on the conveyor belt 4 to move synchronously. When the material sheet moves directly below the upper die 5, the upper die 5 begins to move downward. The movement of the upper die 5 drives the pressure rod 7 to move downward synchronously. The pressure roller 8 first contacts the material sheet. The upper die 5 continues to move downward, and the pressure rod 7, along with the pressure roller 8, rotates around the hinge seat 6 as the center. The rotation of the pressure rod 7 pulls the tension spring 9, and the pressure roller 8 squeezes the material sheet. The upper die 5 and the lower die 18 die-cut the material sheet, finally forming the brim. Then the upper die 5 moves upward, and the movement of the upper die 5 drives the pressure rod 7 to move upward synchronously. After the pressure roller 8 is removed from the material sheet, the elastic potential energy of the tension spring 9 pulls the pressure rod 7 back to the initial position, preparing for the next die-cutting.

[0029] Furthermore, to avoid excessively long sheet lengths, such as Figure 1 , Figure 2 and Figure 3 As shown, a first electric push rod 10 is fixedly connected to the bottom of the top frame 3, and an upper cutter 11 is fixedly connected to the movable end of the first electric push rod 10. A lower cutter 12 is fixedly connected to the top of the die-cutting frame 2.

[0030] An inclined guide plate 13 is fixedly connected to one side of the lower cutter 12, and multiple limiting plates 14 are fixedly connected to the top of the die-cutting frame 2. The limiting plates 14 are arranged in a linear array on both sides of the conveyor belt 4.

[0031] When using the die-cutting device for brim processing, the material sheet is first manually placed onto the conveyor belt 4. The material sheet is then limited by two rows of limiting plates 14 to prevent the limiting plates 14 from shifting during movement. Then, the external motor is started to drive the conveyor belt 4 to rotate synchronously. The rotation of the conveyor belt 4 drives the material sheet to move synchronously. After the material sheet is long enough, the first electric push rod 10 at the bottom of the top frame 3 is started. The movable end of the first electric push rod 10 drives the upper cutter 11 to move downward synchronously. The material sheet is cut by the cooperation of the upper cutter 11 and the lower cutter 12. The material sheet is then guided by the inclined guide plate 13 to ensure that the material sheet stays on the conveyor belt 4.

[0032] In order to facilitate the fit between the upper mold 5 and the lower mold 18, such as Figure 1 , Figure 2 and Figure 3 As shown, a second electric push rod 15 is fixedly connected to the bottom of the top frame 3, and the movable end of the second electric push rod 15 is fixedly connected to the top of the upper mold 5. A lower baffle 16 is fixedly connected to the bottom of the die-cutting frame 2.

[0033] The top of the lower baffle 16 is fixedly connected to the third electric push rod 17, the bottom of the lower mold 18 is fixedly connected to the movable end of the third electric push rod 17, the top of the die-cutting frame 2 is fixedly connected to the limit rod 19, the end of the limit rod 19 away from the die-cutting frame 2 is fixedly connected to the bottom of the top frame 3, and the upper mold 5 is slidably connected to the side surface of the limit rod 19.

[0034] When the die-cutting device for brim processing is in use, as the material sheet is conveyed between the upper die 5 and the lower die 18 via the conveyor belt 4, the second electric push rod 15 and the third electric push rod 17 are simultaneously activated. The extension of the movable ends of the second electric push rod 15 and the third electric push rod 17 drives the upper die 5 to move downward synchronously and the lower die 18 to move upward synchronously, respectively. Under the extrusion and heating of the upper die 5 and the lower die 18, the material sheet is bent and shaped. At the same time, the excess burrs on the edge of the material sheet are trimmed by the upper die 5 and the lower die 18. Then, the movable ends of the second electric push rod 15 and the third electric push rod 17 retract, driving the upper die 5 to move upward synchronously and the lower die 18 to move downward synchronously, respectively, thus completing the entire brim forming process.

[0035] Furthermore, to facilitate the collection of the die-cut brims, such as... Figure 1 , Figure 2 and Figure 3 As shown, a feeding plate 20 is hinged to one side of the upper mold 5, and limiting rollers 22 are fixedly connected to both sides of the feeding plate 20. A collection box 21 is movably connected to the top of the bottom plate 1. Through grooves are opened on both sides of the collection box 21, and the limiting rollers 22 are slidably connected inside the through grooves.

[0036] When the die-cutting device for processing the brim is in use, the material sheet is bent and shaped by the extrusion and heating of the upper die 5 and the lower die 18. At the same time, the excess burrs on the edge of the material sheet are cut off by the upper die 5 and the lower die 18. Then, the movable end of the second electric push rod 15 retracts, driving the upper die 5 to move upward synchronously. During the upward movement of the upper die 5, the material plate 20 moves upward synchronously. Since the limiting rollers 22 on both sides of the material plate 20 are inside the through grooves opened on the collection box 21, the limiting rollers 22 are limited by the through grooves. During the upward movement of the upper die 5, the material plate 20 is driven to rotate around the hinge point with the upper die 5 as the center. Finally, the material plate 20 is in an inclined state, and the die-cut brim slides through the surface of the material plate 20 into the inside of the collection box 21 for collection.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
