[0035] 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.

[0036] Example 1

[0037] Please see Figure 1-4 The present invention provides the following technical solution:

[0038] An automatic metal sign cutting machine, comprising:

[0039] Processing table 1;

[0040] The processing base 2 is fixedly connected to the upper end of the processing table 1. The inner surface of the processing base 2 is provided with a cutting pad 3. Multiple fixing rods 5 are fixedly connected to the upper end of the processing table 1.

[0041] Mounting bracket 6 is fixedly connected to the upper end of multiple fixing rods 5. A motor 17 is fixedly connected to the upper end of the mounting bracket 6. A protective shell 7 is provided on the surface of the motor 17. The output end of the motor 17 movably passes through the lower end of the mounting bracket 6.

[0042] A sealing disc 20 is fixedly connected to the lower end of the mounting bracket 6, and a cutting blade 9 is provided on the lower side of the sealing disc 20; and

[0043] A cutting mechanism is installed on the upper side of the processing table 1 to cut the metal sign placed on the surface of the processing seat 2.

[0044] In a specific embodiment of this utility model, the processing table 1 serves as the basic platform of the entire equipment, providing stable support and a mounting foundation, supporting the processing base 2 and other related components.

[0045] Fixed to the upper end of the processing table 1, the mounting bracket 6 is used to place the metal identification tags to be cut. The fixing rod 5 is fixed to the upper end of the processing table 1 and extends upwards to support the mounting bracket 6, enhancing the stability of the overall structure and providing fixed mounting points for other key components. The mounting bracket 6 is connected to the processing table 1 via the fixing rod 5. Key components such as the motor 17, drive gear 18, and driven gear 19 are mounted on the mounting bracket 6, serving as the main support structure for these moving parts and ensuring their stable operation. The motor 17 is mounted on the top of the mounting bracket 6 and connected to the drive gear 18 through its output end, providing support for the entire cutting process. The machine provides power, and the starting of motor 17 drives the drive gear 18 to rotate, thereby driving the entire cutting mechanism. Driven gears 19 are installed inside the mounting bracket 6 and mesh with the drive gear 18. Each driven gear 19 is fixedly connected to the upper end of a lead screw 23, so that the lead screw 23 can rotate synchronously. The function of the driven gear 19 is to transmit the rotational motion of the drive gear 18 to the lead screw 23. Nut 21 is threaded onto the circumferential surface of the lead screw 23. As the lead screw 23 rotates, the nut 21 moves up and down and transmits the motion to the lower pressure block 24 through the connecting block 22, ultimately driving the cutting blade 9 to cut. The cutting blade 9 is cut by connecting block 22, which is fixedly connected to the outer surface of nut 21 and extends downward to pressure block 24. This converts the vertical movement of nut 21 into pressure on pressure block 24, allowing pressure block 24 to move smoothly downward and push the cutting blade 9 for cutting. Sealing disc 20 is fixed to the lower end of mounting bracket 6, protecting the internal mechanical structure and preventing dust and other impurities from entering the cutting mechanism. It also ensures the normal operation of components such as screw 23 and nut 21. The cutting blade 9 and multiple pressure blocks 24 are fixed together, responsible for the actual cutting operation. The pressure applied by the multiple pressure blocks 24 presses the blade against the surface of the mounting bracket 6. The metal signs on the workbench 2 are precisely cut, which enhances the cutting force of the automatic cutting machine on the metal signs and solves the problems of incomplete or inadequate cutting during the cutting process. This avoids the need for secondary cutting of the metal signs, improves the cutting efficiency of the metal signs, and reduces the waste of time and resources. It should be noted that the specific model of motor 17 and cutting blade 9 used shall be selected by those skilled in the art, and the motor 17 and cutting blade 9 mentioned above are all existing technologies, which will not be elaborated in this solution.

[0046] Please refer to the details. Figure 4 The cutting mechanism includes:

[0047] The driving gear 18 is fixedly connected to the output end of the motor 17. Multiple driven gears 19 are rotatably connected to the inner surface of the mounting bracket 6. The multiple driven gears 19 and the driving gear 18 are all meshed.

[0048] Multiple lead screws 23 are provided, the upper ends of which movably pass through the upper end of the sealing disc 20 and are fixedly connected to multiple driven gears 19. Nuts 21 are threadedly connected to the circumferential surfaces of the multiple lead screws 23, and limit blocks 25 are fixedly connected to the lower ends of the multiple lead screws 23.

[0049] The pressing component is located on the upper side of the processing table 1 to drive the cutting blade 9 to perform pressing and cutting.

[0050] In this embodiment: the motor 17 is mounted on the top of the mounting frame 6 and connected to the drive gear 18 through its output end. When the motor 17 starts, the drive gear 18 starts to rotate, providing power to the entire cutting mechanism. Multiple driven gears 19 are installed inside the mounting frame 6 and mesh with the drive gear 18. Each driven gear 19 is fixedly connected to the upper end of a lead screw 23, so that the lead screw 23 can rotate synchronously. As the lead screw 23 rotates, the nut 21 moves up and down. This up and down movement is transmitted to the lower pressure block 24 through the connecting block 22, converting the vertical movement of the nut 21 into pressure on the lower pressure block 24. The lower pressure block 24 is fixedly connected to the lower end of the connecting block 22 and directly contacts the cutting blade 9. When the lower pressure block 24 is subjected to pressure from above, it pushes the cutting blade 9 to move downward, precisely cutting the metal sign placed on the processing seat 2.

[0051] Please refer to the details. Figure 4 The pressing component includes:

[0052] Multiple connecting blocks 22 are fixedly connected to the outer surface of multiple nuts 21. The lower ends of multiple connecting blocks 22 are fixedly connected to pressing blocks 24. The lower ends of multiple pressing blocks 24 are fixedly connected to the upper ends of cutting blades 9.

[0053] In this embodiment: the vertical movement of the nut 21 is converted into pressure on the lower pressure block 24 by the connecting block 22. The lower pressure block 24 is fixedly connected to the lower end of the connecting block 22 and directly contacts the cutting blade 9. When the lower pressure block 24 is subjected to pressure from above, it will push the cutting blade 9 to move downward and accurately cut the metal sign placed on the processing seat 2.

[0054] Please refer to the details. Figure 3 The outer surface of the mounting bracket 6 is fixedly connected to two fixing seats 8, and the upper end of the cutting blade 9 is fixedly connected to two lower pressure plates 10. The upper ends of the two fixing seats 8 and the two lower pressure plates 10 are all fixedly connected to two connecting seats 11.

[0055] In this embodiment: the fixed base 8 is fixed on the outer surface of the mounting bracket 6 to provide a mounting base for the electric push rod 16. The lower pressure plate 10 is fixed on the upper end of the cutting blade 9 and connected to the sliding shell 12 through the connecting seat 11 to provide additional support during the cutting process and ensure that the cutting force is evenly distributed. Multiple connecting seats 11 are fixed to the upper ends of the fixed base 8 and the lower pressure plate 10 respectively, serving as the mounting points for the sliding shell 12 and the sliding rod 15, ensuring that the relative positions between the various components are accurate and supporting the normal operation of the entire auxiliary mechanism.

[0056] Please refer to the details. Figure 3 It also includes two sets of auxiliary mechanisms, which include:

[0057] Electric push rod 16 is fixedly connected to the upper and lower ends of the lower pressure plate 10 and the fixed base 8 respectively. The inner surfaces of the two upper connecting bases 11 are rotatably connected to the sliding shell 12 through the rotating shaft.

[0058] Two sliding rods 15 are rotatably connected to the inner surfaces of the two connecting seats 11 located on the lower side via rotating shafts. The outer surfaces of the two sliding rods 15 and the inner surfaces of the two sliding shells 12 are slidably connected.

[0059] An elastic component is provided inside the sliding shell 12 to limit the movement of the two sliding rods 15.

[0060] In this embodiment: the sliding shell 12 is rotatably connected to the connecting seat 11 via a rotating shaft, and the pressing seat 14 is slidably connected to its inner surface. The sliding shell 12 allows the sliding rod 15 to slide freely inside it. The spring 13 is disposed on the inner surface of the sliding shell 12 and connected to the pressing seat 14. The function of the spring 13 is to provide elastic support, help maintain a stable cutting force, absorb impact and keep the operation smooth. The lower end of the pressing seat 14 is fixed to the upper end of the sliding rod 15 to ensure that the sliding rod 15 can slide freely inside the sliding shell 12 while remaining stable. At the same time, the function of the sliding rod 15 is to adjust the position of the auxiliary mechanism to ensure the accuracy and stability of the cutting process. The electric push rod 16 provides power to push the lower pressure plate 10 to slide downward, cooperating with the cutting mechanism to perform the downward cutting work, ensuring the flexibility and accuracy of the cutting process. It should be noted that the specific model of the electric push rod 16 used can be selected by those skilled in the art, and the electric push rod 16 and the above are all prior art, which will not be elaborated in this solution.

[0061] Please refer to the details. Figure 3 Each set of elastic components includes:

[0062] Two springs 13 are respectively disposed on the inner surfaces of two sliding shells 12. Each inner surface of the two sliding shells 12 is slidably connected to a pressing seat 14. The lower ends of the two pressing seats 14 and the upper ends of the two sliding rods 15 are respectively fixedly connected.

[0063] In this embodiment, the spring 13 is disposed on the inner surface of the sliding shell 12 and connected to the extrusion seat 14. The function of the spring 13 is to provide elastic support, help maintain a stable cutting force, absorb impact and keep the operation smooth, and ensure the accuracy and stability of the cutting process.

[0064] Please refer to the details. Figure 1 Multiple limiting seats 4 are fitted on the outer surface of the processing base 2, and the lower ends of the multiple limiting seats 4 are fixedly connected to the upper end of the processing table 1.

[0065] In this embodiment, the installation and fixing strength of the machining base 2 is enhanced by setting four limiting seats 4 at the four corners of the surface of the machining base 2, thus avoiding the phenomenon of the machining base 2 tilting during machining.

[0066] The working principle and usage process of this utility model are as follows: First, the metal sign to be processed is placed on the upper end of the processing base 2. Then, the motor 17 is started to drive the drive gear 18 to rotate. Since multiple driven gears 19 mesh with the drive gear 18, multiple driven gears 19 and multiple lead screws 23 are driven to rotate synchronously. As the multiple lead screws 23 rotate, multiple nuts 21 move up and down and are transmitted to multiple pressing blocks 24 through multiple connecting blocks 22. Finally, the cutting blade 9 is driven to cut. At the same time, the electric push rod 16 is controlled to provide power to push the pressing plate 10 to slide downward. In conjunction with the cutting mechanism, the metal sign placed on the processing base 2 is precisely cut.

[0067] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
