[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A waste removal structure for an air-blowing die includes a hollow die 1, an air inlet mechanism 7 on the left side of the hollow die 1, an air-blowing die-cutting mechanism 9 inside the hollow die 1, a servo motor 3 on the right side of the hollow die 1, and a mounting plate 5 on the top of the hollow die 1.

[0029] The air-blowing die-cutting mechanism 9 includes several circular cutting edges 901, several air-blowing holes 902, two shafts 903, and two die sleeves 904. The air-blowing holes 902 are opened on the surface of the hollow die 1. The circular cutting edges 901 are fixedly connected to the inner wall of the air-blowing holes 902. The side of the shaft 903 near the hollow die 1 is fixedly connected to the hollow die 1. The side of the shaft 903 near the die sleeve 904 extends into the interior of the die sleeve 904 and is movably connected to the interior of the die sleeve 904.

[0030] In this embodiment: an air compressor 703 is fixed to the workbench via a bracket 8. Compressed air is regulated by a flow control valve 702 and delivered to the hollow die 1 through a rigid air inlet pipe 701. A servo motor 3 is connected to the shaft 903 of the hollow die 1 to drive its rotation. The circular cutting edge 901 on the die is designed according to the material to precisely cut it. Simultaneously, compressed air is blown out from the air outlet 902 to act on waste material. Due to its positional relationship with the circular cutting edge 901, waste can be discharged in a timely manner, preventing accumulation that could affect cutting quality and efficiency. The mounting plate 5 is fixed to the equipment with fixing screws 14. The connecting ring 2, connecting bracket 6, and second screw 11 ensure the stable installation of the die sleeve 904 and the servo motor 3, guaranteeing power output. This technology enables simultaneous cutting and waste removal, effectively solving the problems of low and incomplete waste removal efficiency in traditional air-blowing dies. It avoids production stoppages, impacts on product quality, and potential equipment malfunctions. It also addresses the issue of low waste removal efficiency in some existing air-blowing dies, which cannot meet the demands of rapid production and lead to frequent production stops for waste removal. This severely affects overall production efficiency and hinders the continuous operation of large-scale production. Furthermore, waste often leaves residues during waste removal, especially for complex shapes and small-sized waste materials, which traditional air-blowing dies struggle to remove completely. This not only affects product quality but may also cause equipment malfunctions or product defects in subsequent processing.

[0031] Specifically, such as Figure 1 As shown, the air intake mechanism 7 includes a rigid air intake pipe 701, a flow control valve 702, and an air compressor 703. The bottom of the flow control valve 702 is fixedly connected to the top of the air compressor 703, and the bottom of the rigid air intake pipe 701 is fixedly connected to the top of the flow control valve 702. The side of the rigid air intake pipe 701 near the left die sleeve 904 passes through the left die sleeve 904 and the left shaft 903 and extends into the interior of the hollow die 1. The surface of the rigid air intake pipe 701 is in movable contact with the inner wall of the left shaft 903.

[0032] Specifically, such as Figure 1 As shown, the bottom of the air compressor 703 is fixedly connected to a bracket 8, and there are four brackets 8 evenly distributed on the bottom of the air compressor 703.

[0033] Specifically, such as Figure 2 and Figure 5 As shown, a limiting strip 10 is fixedly connected to the surface of the die sleeve 904, and a connecting ring 2 is sleeved on the surface of the die sleeve 904. A limiting groove 15 is opened inside the connecting ring 2. The surface of the limiting strip 10 is in contact with the inner wall of the limiting groove 15. There are two limiting strips 10 and two limiting grooves 15.

[0034] In this embodiment: compressed air can be generated by controlling the operation of the air compressor 703, and is introduced into the hollow die 1 through the rigid air inlet pipe 701. The flow rate of the gas entering the hollow die 1 can be controlled by the flow control valve 702. The air compressor 703 can be easily fixed on the worktable by the support bracket 8. The connection ring 2 will not rotate after it is sleeved on the surface of the die sleeve 904 by the contact between the limiting strip 10 and the limiting groove 15.

[0035] Specifically, such as Figure 1 and Figure 5 As shown, a connecting bracket 6 is fixedly connected to the top of the connecting ring 2. A first screw 16 is provided on the front and rear sides of the bottom of the connecting bracket 6. The top of the first screw 16 passes through the connecting bracket 6 and is connected to the internal thread of the mounting plate 5.

[0036] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the left side of the output shaft of the servo motor 3 passes through the right die sleeve 904 and is fixedly connected to the right side of the right shaft 903.

[0037] In this embodiment: by passing the top of the first screw 16 through the connecting frame 6 and connecting it with the internal thread of the mounting plate 5, the connecting frame 6, the connecting ring 2 and the die sleeve 904 can be connected to the mounting plate 5. By controlling the rotation of the servo motor 3, the output shaft can drive the hollow die 1 to rotate through the shaft body 903.

[0038] Specifically, such as Figure 3 As shown, a fixing plate 12 is fixedly connected to the surface of the servo motor 3. There are two fixing plates 12, and a mounting bracket 4 is fixedly connected between the tops of the two fixing plates 12.

[0039] Specifically, such as Figure 5 As shown, a second screw 11 is provided on both the front and rear sides of the top of the mounting bracket 4. The bottom of the second screw 11 passes through the mounting bracket 4 and is connected to the internal thread of the mounting plate 5.

[0040] In this embodiment: the servo motor 3 is connected to the mounting bracket 4 through the fixing plate 12, and then the mounting bracket 4 is brought into contact with the mounting plate 5. The bottom of the second screw 11 is passed through the mounting bracket 4 and connected to the internal thread of the mounting plate 5, so that the servo motor 3 and the mounting plate 5 can be connected.

[0041] Specifically, such as Figure 1 and Figure 4 As shown, there are fixing screws 14 at the four corners of the bottom of the mounting plate 5. The top of the fixing screws 14 passes through the mounting plate 5 and extends to the top of the mounting plate 5.

[0042] Specifically, such as Figure 4 As shown, pads 13 are fixedly connected to both sides of the top of the mounting plate 5.

[0043] In this embodiment: by passing the top of the fixing screw 14 through the mounting plate 5 and connecting it to the installation position, the mounting plate 5 can be easily fixed. The pads 13 on both sides of the top of the mounting plate 5 can play a supporting role, so that the installation of the mounting plate 5 can be stable.

[0044] Working principle: The air compressor 703 is controlled to operate. The bottom of the air compressor 703 is stably fixed to the worktable by four evenly distributed supports 8. The air compressor 703 is responsible for compressing air to generate an airflow with a certain pressure. The flow control valve 702 is connected to the top of the air compressor 703 to control the flow rate. By adjusting the flow control valve 702, the gas flow rate entering the hollow die 1 can be adjusted according to different cutting materials and waste discharge requirements. The bottom of the rigid air inlet pipe 701 is fixedly connected to the top of the flow control valve 702, and the top extends through the left die sleeve 904 and the left shaft 903 into the interior of the hollow die 1. The surface of the rigid air inlet pipe 701 is movably connected to the inner wall of the left shaft 903. To ensure smooth gas flow from the air compressor 703 to the interior of the hollow die 1, the air-blowing die-cutting mechanism 9 includes several circular cutting edges 901, air holes 902, two shafts 903, and two die sleeves 904. The output shaft of the servo motor 3 is connected to the right shaft 903 via the right die sleeve 904. When the servo motor 3 rotates, its power is transmitted through the shaft 903, driving the hollow die 1 to rotate. Several air holes 902 are provided on the surface of the hollow die 1, and a circular cutting edge 901 is fixedly connected to the inner wall of each air hole 902. When the material is conveyed to the bottom of the hollow die 1, the circular cutting edges 901 will cut the material under the drive of the servo motor 3. The shape and arrangement of the circular cutting edges 901 can be adjusted according to the material being cut and the required shape. The design is consistent with the actual cutting effect. Compressed air from the air intake mechanism 7 enters the hollow die 1 through the rigid air intake pipe 701 and is then blown out through the air blowing hole 902. The airflow from the air blowing hole 902 directly acts on the waste material generated during cutting, using the force of the airflow to blow the waste material away from the cutting area. Due to the positional relationship between the air blowing hole 902 and the circular cutting edge 901, waste material can be blown away promptly during or after cutting, preventing waste material from accumulating in the cutting area and affecting cutting quality and efficiency. The mounting plate 5 is fixed to the corresponding equipment by the fixing screws 14 at the four corners of the bottom. The pads 13 on both sides of the top of the mounting plate 5 provide support, ensuring stable installation of the mounting plate 5. The connecting ring 2 is connected by its internal limiting groove. The limiting strip 10 on the surface of the die sleeve 904 is movably connected to the 15, ensuring the stability and precise position of the die sleeve 904. The connecting bracket 6 at the top of the connecting ring 2 is fixed to the mounting plate 5 by the first screws 16 on the front and rear sides, further stabilizing the connection between the die sleeve 904 and the mounting plate 5. Two fixing plates 12 are fixedly connected to the surface of the servo motor 3. The mounting bracket 4 between the tops of the two fixing plates 12 is threadedly connected to the mounting plate 5 by the second screws 11 on the front and rear sides, so that the servo motor 3 is stably mounted on the mounting plate 5, ensuring that the servo motor 3 provides stable power output to the hollow die 1. The circular cutting edge 901 of the hollow die 1 is driven by the servo motor 3 to cut the material, while the compressed air generated by the air compressor 703 is used.The air blower 902 promptly blows away the waste generated during cutting, achieving simultaneous cutting and waste removal. This ensures efficient cutting and waste removal, avoiding the low waste removal efficiency of some existing air-blowing dies, which cannot meet the demands of rapid production and require frequent stoppages to clean up waste, severely impacting overall production efficiency and hindering continuous large-scale production. Furthermore, waste often leaves residue during cleaning, especially for complex shapes and small-sized waste, which traditional air-blowing dies struggle to remove completely. This not only affects product quality but may also cause equipment malfunctions or product defects in subsequent processing. It should be noted that the air compressor 703 and flow control valve 702 are existing, published, and mature technologies with diverse appearances; therefore, they will not be described in detail here.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
