[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , the utility model provides the following technical solutions:

[0023] An automatic waste rejection tool for a die-cutting machine, comprising:

[0024] The die-cutting device 4 is located between the conveyor belt 1 and the conveyor belt 2 5, and is used to die-cut the finished roll film; it also includes: a high-definition camera 2 and a puncher 3, which are located above the conveyor belt 1 and are used to punch holes in products that do not meet the standards and mark them as defective products.

[0025] The high-definition camera 2 has a strong background light, which keeps the clarity of the image and the size of the field of view in the best balance. According to the actual pattern, the template of qualified products is set in the computer, and the grade standard of defective products is set by comparing with the template of qualified products before die-cutting.

[0026] Before sampling, several qualified samples are tested to formulate a standard sample, and then a lower limit value φ is set based on this standard sample. The finished film roll is placed on the conveyor belt 1, and the conveyor belt 1 makes the finished film roll to the right (such as Figure 1 The right side shown in the figure (i.e., the conveyor belt conveying direction) is driven, and when the finished roll film passes through the high-definition camera 2, the high-definition camera 2 will take a photo, which will be compared by the control device. When the finished roll film passes under the punching machine 3, according to the detection result, the sample punching machine 3 below the set value φ will be marked with a punch hole, and the control device marks the product punched by the punching machine 3 as a defective product. The conveyor belt 1 inputs the finished roll film into the die-cutting device 4, and the die-cutting device 4 processes the finished roll film.

[0027] The air blowing device 7 is arranged above the conveyor belt 2 5 in the running direction, and is used to blow up the defective products for primary rejection. A detection device 1 6 is installed above the conveyor belt 2 5 at one end close to the die-cutting device 4. The air blowing device 7 is located above the conveyor belt 2 5 at one end away from the die-cutting device 4. The defective products passing through the detection device 1 6 are blown up by the air blowing device 7 and fall off the conveyor belt 2 5.

[0028] The finished products after die-cutting by the die-cutting equipment 4 will enter the conveyor belt 2 5. The finished products transported to the conveyor belt 2 5 are arranged in a row and pass through the detection device 1 6. The detection device 1 6 can determine the defective products by identifying the punch marks. When the defective products pass through the blowing device 7, the control device controls the blowing device 7 to blow air to the defective products. The airflow blows the defective products off the conveyor belt 2 5. The remaining finished products that pass the detection are transported to the conveyor belt 3 8 via the conveyor belt 2 5.

[0029] The fault mechanism includes a detection device 2 9 and a stacking device 11. The detection device 2 9 is located above the conveyor belt 3 8. The stacking device 11 is arranged on the conveyor belt 4 10. The installation height of the conveyor belt 2 5 is higher than that of the conveyor belt 3 8. The height difference between the two is 1-1.5 cm, and the spacing between the two is 2.5-3 cm.

[0030] Since the irregularity of the roll film is not completely consistent with the shape of the finished film, the die-cut finished products have irregular shapes such as fan-shaped, circular, square, etc., and there may still be defective products after one rejection. Therefore, the present application sets a detection device 9, which cooperates with the stacking device 11 to perform a secondary rejection operation.

[0031] When the detection device 29 detects defective products that have not been rejected in time, it sends a detection signal to the control device, and the control device starts the stacking device 11 on the conveyor belt 4 10. The control device also adjusts the speed of the conveyor belt 4 10 to create a fault to remind the operator to reject them in time, and the automatic waste rejection process is completed.

[0032] It should be noted that after the fault, a machine structure can also be set up to automatically remove the waste, such as a blowing device, a robot arm and other waste removal structures.

[0033] The finished products that are not rejected are qualified products. The qualified products fall into the collection container through the conveyor belt 410. The machine inspection standard is more stringent and demanding than the manual inspection, which guarantees the product quality to a considerable extent and provides high-quality services to customers.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
