Description

Technical Field

[0001] This invention relates to the field of die-cutting technology, specifically a material feeding system that can reduce the weight of materials. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines or CNC punching machines, are mainly used for die-cutting, semi-die-cutting, creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, and mobile phone pads. They utilize steel blades, metal molds, and steel wires to apply pressure through a printing plate, cutting printed materials or cardboard into specific shapes. They are crucial equipment for post-printing packaging processing. In current automated die-cutting production equipment, two feeding mechanisms on the front and rear sides of the stamping platform transport the material. The material hangs naturally after exiting the machine. However, some materials are quite heavy, causing misregistration during die-cutting due to their weight, affecting processing accuracy and efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a material feeding system that can reduce the weight of materials, thereby solving the technical problems in the background art.

[0004] To achieve the aforementioned objectives, the present invention provides the following technical solution:

[0005] A material feeding system that reduces material weight includes a first feeding mechanism and a second feeding mechanism installed on the left and right sides of a die-cutting machine. A die-cutting pulling mechanism is also installed between the first feeding mechanism and the second feeding mechanism. The first feeding mechanism includes a first frame, a first conveying device and a first guide assembly installed on the first frame. The first conveying device is located to the left of and above the first guide assembly. The first guide assembly is on the same horizontal plane as the die-cutting pulling mechanism. The second feeding mechanism includes a second frame, a second conveying device and a second guide assembly installed on the second frame. The second conveying device is located to the right of the die-cutting pulling mechanism and to the left of the second conveying device. The second conveying device is above the second guide assembly. The second conveying device has the same structure as the first conveying device, and the second guide assembly has the same structure as the first guide assembly.

[0006] The first conveying device includes a first support frame, with a first drive roller and a second drive roller above the first support frame. The first drive roller is located below the second drive roller. A first drive motor is installed outside the first support frame and is connected to the first drive roller. At least two first support rods are provided on the front and rear sides of the first drive roller, and the first support rods are parallel to the first drive roller. A first guide platform is provided on the right side of the first support frame, above a first guide assembly. The first guide platform has a downwardly inclined first slope on the side near the first guide assembly. The die-cutting material pulling mechanism includes a fixed frame and a material pulling roller installed in the fixed frame. A third guide assembly is provided on the left side of the fixed frame. A material pulling motor is installed on the fixed frame and is connected to the material pulling roller. The material pulling motor and the first drive motor drive the first drive roller and the material pulling roller respectively to synchronously convey the material strip.

[0007] The first conveying device further includes a first suction component, which is installed on the front side of the first support frame. The second conveying device further includes a second suction component, which is located on the right side of the second guide component. The first suction component and the second suction component have the same structure.

[0008] The first suction assembly includes a first vacuum adsorption plate with a plurality of first adsorption holes. The first vacuum adsorption plate is installed at an upward tilt. A second guide platform is provided on the right side of the first vacuum adsorption plate. The second guide platform is horizontally set and level with the first guide platform.

[0009] A first proximity sensor is installed between the first conveying device and the first guiding assembly, and a second proximity sensor is installed between the second conveying device and the second guiding assembly.

[0010] The first guide assembly includes a mounting frame and a plurality of guide rollers installed parallel to each other within the mounting frame. The guide rollers are rotatably connected to the mounting frame. At least one limiting roller is provided above the mounting frame. The limiting roller is fixedly connected to the mounting frame through a positioning seat and is rotatably connected to the positioning seat.

[0011] Compared with the prior art, the material feeding system of this application, which can reduce the weight of the material, adds a first conveying device and a second conveying device set at a high position in the first feeding mechanism and the second feeding mechanism, raising the material and eliminating the influence of the material's own weight, thus ensuring accurate positioning. At the same time, in order to solve the cumulative error of feeding, a proximity sensor is added to sense the material position and make fine adjustments when the material and the die-cutting pull are out of sync, effectively improving product quality and work efficiency. In addition, in order to ensure the straightness of the feeding of the entire feeding platform in the later stage of the raised platform, a first suction component and a second suction component are added to ensure that the material is tightened during feeding, ensuring that the material is carried in a straight line.

The first conveying device 5 is to the left of the first guiding assembly 4 and above the first guiding assembly 4. The first guiding assembly 4 and the die-cutting pulling mechanism 15 are on the same horizontal plane. The first frame 3 is higher on the left and lower on the right. The structure facilitates the first conveying device 5 to be in a high position, allowing the material strip to be conveyed from the high position towards the first guide assembly 4 and the die-cutting machine 1; the second feeding mechanism 9 includes a second frame 10, a second conveying device 12 and a second guide assembly 11 mounted on the second frame 10, the second conveying device 12 is on the right side of the die-cutting feeding mechanism 15 and on the left side of the second conveying device 12, the second conveying device 12 is above the second guide assembly 11, the second conveying device 12 has the same structure as the first conveying device 5, and the second guide assembly 11 has the same structure as the first guide assembly 4, so it will not be described again.

[0021] The first conveying device 5 includes a first support frame 504. A first drive roller 501 and a second drive roller 502 are arranged above the first support frame 504. The first drive roller 501 is below the second drive roller 502. A first drive motor 503 is installed outside the first support frame 504 and is connected to the first drive roller 501 for driving. At least two first support rods 505 are arranged on the front and rear sides of the first drive roller 501, and the first support rods 505 are parallel to the first drive roller 501. A first guide platform 7 is arranged on the right side of the first support frame 504. The first guide platform 7 is above the first guide assembly 4. The first guide platform 7 has a downwardly inclined first slope on the side near the first guide assembly 4. The first slope facilitates the material belt to be guided to the first guide assembly. The die-cutting material pulling mechanism 15 includes a fixed frame 1501 and a pulling roller 1502 installed in the fixed frame 1501. A third guide assembly 1504 is provided on the left side of the fixed frame 1501. A pulling motor is installed on the fixed frame 1501 and is driven by the pulling roller 1502. The pulling motor and the first drive motor 503 drive the first drive roller 501 and the pulling roller 1502 respectively to transport the material belt synchronously. The third guide assembly 1504 includes a positioning frame 1504-1. Several support rollers 1504-2 are arranged horizontally in the positioning frame 1504-1. The support rollers 1504-2 are rotatably connected to the positioning frame 1504-1. The third guide assembly 1504 is on the right side of the die-cutting machine 1.

[0022] The first conveying device 5 also includes a first suction component 6, which is installed on the front side of the first support frame 504. The second conveying device 12 also includes a second suction component 13, which is located on the right side of the second guide component 11.

This increases the proximity sensor's ability to detect the material's position, resolves the cumulative error in material feeding, and allows for fine-tuning when the material and die-cutting are out of sync, achieving precise positioning and conveying.

[0024] The first guide assembly 4 includes a mounting frame 301 and a plurality of guide rollers 302 installed parallel to each other within the mounting frame 301.

In this application, two limiting rollers 303 with the same structure are provided on the mounting frame 301. The limiting rollers 303 are fixedly connected to the mounting frame 301 through a positioning seat 304 and are rotatably connected to the positioning seat 304. The limiting rollers 303 limit the conveying of the material belt to prevent the material belt from being misaligned to the outside of the machine.

[0025] Compared with the prior art, the material feeding system of this application, which can reduce the weight of the material, adds a first conveying device and a second conveying device set at a high position in the first feeding mechanism and the second feeding mechanism, raising the material and eliminating the influence of the material's own weight, thus ensuring accurate positioning. At the same time, in order to solve the cumulative error of feeding, a proximity sensor is added to sense the material position and make fine adjustments when the material and the die-cutting pull are out of sync, effectively improving product quality and work efficiency. In addition, in order to ensure the straightness of the feeding of the entire feeding platform in the later stage of the raised platform, a first suction component and a second suction component are added to ensure that the material is tightened during feeding, ensuring that the material is carried in a straight line.
