Description

Technical Field

[0001] The utility model relates to the technical field of die cutting, in particular to a pneumatic blanking and waste discharging device. Background Art

[0002] In the die-cutting industry, flat knife machines play a vital role. They are mainly used to stamp products with hole features. These products are often highly dependent on the metal die in the metal stamping parts for precise processing. By using flat knife machines, various complex shapes and sizes of hole stamping tasks can be completed efficiently to ensure product quality and precision.

[0003] For example, Chinese patent CN202120619196.8 discloses a flat-knife die-cutting waste extraction device. This solution quickly extracts and removes the waste upwards during die-cutting, reducing the risk of defective products with overflowed glue sticking back. At the same time, there is no need to replace the product base film during later shipment.

[0004] However, the metal die cutters used in metal stamping parts are expensive, and the product size is often too small to meet the use requirements, which brings troubles. The method of adding auxiliary materials to eliminate waste has further led to an increase in costs. After the die-cutting parts are completed, the elimination of hole waste still depends on manpower, which not only increases the cost of leakage, but also increases labor costs.

[0005] Based on this, the utility model designs a pneumatic blanking and waste discharge device to solve the above problems. Utility Model Content

[0017] Third, through the coordinated use of the feeding rack, the feeding roller, and the guiding roller, the stable supply of materials is ensured, improving the working efficiency of the die-cutting and stamping machine. The design of the support frame and the auxiliary frame provides good support and stability for the device.

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See also Figures 1-5 The pneumatic blanking and waste discharge device comprises a die-cutting and punching machine 1. A discharge plate 2 is fixedly connected to the right side of the die-cutting and punching machine 1. A blanking trough 3 is provided at the center of the discharge plate 2. A fixed frame 4 is arranged on the top of the blanking trough 3. The fixed frame 4 is fixedly connected to the top of the discharge plate 2. A pneumatic mechanism 5 is arranged directly above the fixed frame 4. The pneumatic mechanism 5 is fixedly mounted on a mounting plate 6. The mounting plate 6 is fixedly connected to the right side of the die-cutting and punching machine 1. The pneumatic mechanism 5 is connected to the fixed frame 4 through transmission. A connecting plate 7 is also fixedly connected to the right side of the die-cutting and punching machine 1. A guide plate 8 is fixedly connected to the right side of the connecting plate 7. A waste collection box 9 is arranged at the right end of the guide plate 8.

[0026] Specifically, according to the stamping action (up and down) of the die-cutting stamping machine 1 itself, the forming process of the product's outer shape is realized. With the powerful pressure of the die-cutting stamping machine 1, an air hose is connected to and provides power for the air compressor 501 in the pneumatic mechanism 5. After the air compressor 501 is started, the pressing plate 502 is pushed to move up and down by air pressure, thereby driving the limit rod 503 to move synchronously and embed into the corresponding groove on the fixing frame 4, ensuring the stability of the pneumatic mechanism 5 during the stamping process, and realizing the up and down pressing action. Following the up and down operation of the die-cutting machine, the pneumatic mechanism 5 stamps at the die holes in the punching plate 402, so that the hole waste of the workpiece after being die-cut by the die-cutting stamping machine 1 on the discharge plate 2 is stamped and removed. After the hole waste is stamped, it falls on the guiding plate 8 through the blanking chute 3 and is guided into the waste collection box 9 by the guiding plate 8, thus realizing the one-to-one up and down blanking action.

[0027] Furthermore, an installation groove 401 is provided at the central position of the fixing frame 4. The punching plate 402 is detachably connected in the installation groove 401. A blanking chute 3 is correspondingly arranged at the bottom of the punching plate 402. The detachably arranged punching plate 402 can be replaced according to different die-cutting shape requirements, realizing the targeted random blanking of the hole waste of each product, and achieving the purpose of reducing materials and labor costs.

[0028] Furthermore, the pneumatic mechanism 5 includes an air compressor 501, a pressing plate 502, and a limit rod 503. The air compressor 501 is fixedly installed at the bottom of the installation plate 6. The pressing plate 502 is fixedly installed at the bottom of the air compressor 501. The limit rods 503 are fixedly connected to the bottom corners of the pressing plate 502. The pneumatic mechanism 5 realizes the up and down movement action driven by the die-cutting stamping machine 1. The air compressor 501 pushes the pressing plate 502 to move up and down by air pressure, and punches and removes the hole waste of the workpiece that has moved to the bottom of the punching plate 402 on the discharge plate 2. While the die-cutting stamping machine 1 performs the stamping operation on the workpiece, the waste removal operation is automatically carried out, realizing the rapid and accurate removal of waste, improving the production efficiency and product quality, and reducing the labor cost.

[0029] Furthermore, the connecting plate 7 is arranged at the bottom of the discharge plate 2. The guiding plate 8 is inclined, and the guiding plate 8 is located at the bottom of the installation groove 401, so that the waste can smoothly slide into the waste collection box 9 along the guiding plate 8 after being stamped, improving the efficiency and accuracy of waste collection.

[0030] Furthermore, a feeding frame 10 is connected to the left side of the die-cutting stamping machine 1. A feeding roller 11 is rotatably connected to the left side of the top of the feeding frame 10. A guiding roller 12 is arranged on the right side of the feeding roller 11. The guiding roller 12 is rotatably connected to the feeding frame 10, ensuring the continuous supply of materials and improving the production efficiency.

[0031] Furthermore, a support frame 13 is fixedly connected to the left side of the top of the discharge plate 2. An auxiliary frame 14 is fixedly connected to the center position of the support frame 13. An auxiliary wheel 15 is rotatably connected to the auxiliary frame 14. The auxiliary wheel 15 makes the discharge plate 2 more stable during the blanking operation, reducing the vibration and noise of the equipment.

[0032] Furthermore, a sensor 16 is fixedly installed on the left side of the mounting plate 6. The sensing head of the sensor 16 penetrates and extends to the bottom of the mounting plate 6. The sensor 16 can sense the workpiece after it has been die-cut by the die-cutting and stamping machine 1 and perform induction after the workpiece exits the die-cutting and stamping machine 1, thereby realizing automatic counting and quality inspection of the workpiece, ensuring the automation and intelligence of the production process, and improving production efficiency and product quality.

[0033] The working principle of the present utility model: When in use, after the die-cutting and stamping machine 1 is started, the workpiece is fed into the die-cutting and stamping machine 1 for processing. Under the stamping action of the die-cutting and stamping machine 1, the outer shape of the workpiece is formed. At the same time, the waste part is stamped out. The waste falls into the guiding plate 8 through the blanking groove 3 and slides into the waste collection box 9 along the guiding plate 8. During this process, the pneumatic mechanism 5, driven by the power provided by the air compressor 501, drives the pressing plate 502 and the limiting rod 503 to move up and down to ensure the stability of the stamping process. When the workpiece has been processed by the die-cutting and stamping machine 1, the sensor 16 senses the workpiece, automatically counts it, and detects the quality of the workpiece. The discharge plate 2, with the assistance of the auxiliary frame 14 and the auxiliary wheel 15, smoothly delivers the workpiece to the connecting plate 7 and the guiding plate 8, and finally falls into the waste collection box 9.
