[0029] See also Figure 1-6 The utility model describes the above technical solution in detail through the following embodiments:

[0030] Label inspection and slitting equipment, including:

[0031] The rack 1 has a control device at the rear side thereof, which is used to control the operation of the equipment. The control device includes an electrical system 10, and an industrial control system 11 is arranged above the electrical system 10. The industrial control system 11 is connected to a plurality of servo motors through wires, and the industrial control system 11 can control the rotation of a single motor.

[0032] The electrical system 10 provides support for the normal operation and automatic control of the equipment. The industrial control system 11 adopts any one of a single chip microcomputer or a PLC controller. The servo motor adopts a well-known 12V DC servo motor.

[0033] The industrial control system 11 is also connected to an audible and visual alarm device 4 and a human-computer interaction interface 5 .

[0034] The sound and light alarm device 4 is used to provide an alarm when the equipment operation is switched to manual, and the human-machine interaction interface 5 is used for the setting of the industrial control system 11.

[0035] A feeding mechanism and a receiving mechanism are provided on the front side of the frame 1, and a slitting system 7 is provided between the feeding mechanism and the receiving mechanism. The slitting system 7 includes a slitting power guarantee roller 17 and a slitting knife 18. The slitting knife 18 is used for slitting the roll label. A detection system is provided between the slitting system 7 and the feeding mechanism.

[0036] The unloading mechanism is used to convey the roll label raw material. The roll label raw material starts from the unloading mechanism, is detected by the detection system and the unqualified parts are removed, and then is cut by the slitting system 7. Finally, the cut roll label is rolled up by the receiving mechanism.

[0037] The material discharging mechanism comprises a material discharging air-inflating shaft 2, on which the roll label raw material is placed, and the material discharging air-inflating shaft 2 can be rotated under the drive of a servo motor.

[0038] The roll label material is in a roll, and the discharge air inflation shaft 2 adopts a known air inflation shaft, which expands after high-pressure gas is introduced and contracts after the gas is discharged. The discharge air inflation shaft 2 can be inserted into the middle of the roll label material and fix the roll label material after expansion. Driven by the servo motor, the discharge air inflation shaft 2 rotates, and the rotation of the discharge air inflation shaft 2 can drive the roll label material to rotate, thereby releasing the roll label.

[0039] A deviation correction system 3 is arranged above the discharge air expansion shaft 2, and a speed control conveying roller 12 and a tension control conveying roller 15 are arranged in parallel above the deviation correction system 3. The speed control conveying roller 12 and the tension control conveying roller 15 can rotate under the drive of a servo motor.

[0040] The correction system 3 adopts a known web correction device, which generally includes a correction sensor and a correction platform, such as Figure 3 and Figure 4 As shown, the deflection correction sensor is generally installed near the discharge position to ensure that the edge of the material on the equipment is always in the same position. During normal operation, the system 3 is generally set to manual centering mode and the equipment is run. After the setting is completed, the deflection correction sensor is slowly moved to the edge of the material. When the green light is displayed on the sensor, it means that the sensor has detected the edge of the material. At this time, the deflection correction system is adjusted to automatic mode. At this time, the platform on the deflection correction system 3 will move together according to the position of the sensor. After fine-tuning, the position of the sensor is locked. At this time, it can be ensured that the raw materials are always discharged along the position set by the sensor.

[0041] There are two speed-controlled conveying rollers 12, which are arranged up and down. The label paper passes between the two speed-controlled conveying rollers 12. The servo motor can drive the speed-controlled conveying rollers 12 to rotate, thereby driving the label paper to move. By controlling the rotation speed of the speed-controlled conveying rollers 12, the forward speed of the label paper can be controlled.

[0042] The tension control conveyor roller 15 is located on the right side of the speed control conveyor roller 12. There are two tension control conveyor rollers 15, which are arranged up and down. The tension control conveyor rollers 15 are driven by a servo motor. The label paper passes between the tension control conveyor rollers 15 and is squeezed by the tension control conveyor rollers 15.

[0043] A plurality of cylinders are vertically arranged between the tension control conveying roller 15 and the speed control conveying roller 12. The cylinders are fixedly mounted on the front side of the frame 1 by bolts. By controlling the extension or retraction of the cylinder piston rod, different pressures can be applied to the label paper, thereby adjusting the surface tension of the label paper.

[0044] The detection system includes a visual detection system 13 , a code reading system 14 and a manual operation platform 16 .

[0045] The visual inspection system 13 and the code reading system 14 are located above the tension control conveying roller 15 and the speed control conveying roller 12. The manual operation platform 16 is located below the right side of the tension control conveying roller 15, and the label paper passes through the upper surface of the manual operation platform 16 after being transmitted from the tension control conveying roller 15.

[0046] The visual inspection system 13 adopts a well-known image inspection system, including an image capture device, an image comparison module, and an image judgment module. The image capture device captures images, the image comparison module performs feature processing on the captured images and sends them to the image judgment module, and the image judgment module distinguishes the captured feature values ​​from the standard values.

[0047] The image recognition module sends the recognition result to the industrial control system 11, and the industrial control system 11 controls the operation of the device.

[0048] The code reading system 14 adopts a well-known code reading device, which generally includes a code reader and a judgment module. The code reader reads the code on the roll label in real time and sends the reading result to the code judgment module. The code judgment module distinguishes the monitoring code from the standard code.

[0049] The code determination module sends the determination result to the industrial control system 11, and the equipment operation is controlled by the industrial control system 11.

[0050] When the visual inspection system 13 or the code reading system 14 determines that the label paper has defects or the code is wrong, the industrial control system 11 controls the wrong label paper to move to the top of the manual operation platform 16, stops the equipment operation, and sends an alarm through the sound and light alarm device 4 to remind the operator to handle it. At the manual operation platform 16, the operator manually handles the wrong label. Then the industrial control system 11 controls the equipment to continue to operate.

[0051] The slitting knife 18 is located on the left side of the slitting power guarantee roller 17. The slitting knife 18 includes two parallel guide rollers 181, and two slitting rollers 182 are arranged vertically between the two guide rollers 181. A plurality of disc cutters 183 are evenly arranged on the upper slitting roller 182, and the same number of slitting disks 184 are arranged at corresponding positions on the lower slitting roller 182. The blades of the disc cutters 183 are inserted into the grooves on the surface of the slitting disks 184, and the roll labels pass between the disc cutters 183 and the slitting disks 184.

[0052] The disc cutter 183 and the slitting disk 184 are slidably mounted on the slitting roller 182 and fixed by screws. After the label paper passes over the manual operation platform 16, it bypasses the left guide roller 181 from the upper left to the right, then enters from the left side of the slitting roller 182, passes out from the right side, and then bypasses the right guide roller 181 from the upper left to the right. When the label paper passes between the disc cutter 183 and the slitting disk 184, it is squeezed and cut by the disc cutter 183 and the slitting disk 184. The width of the label paper is the same as the distance between the two adjacent disc cutters 183. Therefore, by adjusting the distance between the two adjacent disc cutters 183 and the slitting disk 184, the width of the cut label paper can be adjusted.

[0053] A scrap collecting device 9 is provided below the slitting knife 18 , and scraps generated when the labels are slitting will directly fall into the scrap collecting device 9 .

[0054] There are two slitting power guarantee rollers 17 and they are located on the left side of the material receiving mechanism. The two slitting power guarantee rollers 17 are arranged up and down and contact each other. The slitting power guarantee rollers 17 can rotate under the drive of the servo motor, and the roll label passes between the two slitting power guarantee rollers 17.

[0055] After the cut label paper passes around the guide roller 181 on the right side, it passes between the two cutting power guarantee rollers 17. The cutting power guarantee rollers 17 are driven by the servo motor to rotate, thereby driving the cut label paper to move.

[0056] The material receiving mechanism includes a first material receiving air expansion shaft 6 and a second material receiving air expansion shaft 8. The first material receiving air expansion shaft 6 and the second material receiving air expansion shaft 8 are located on the front right side of the frame 1. The first material receiving air expansion shaft 6 and the second material receiving air expansion shaft 8 are arranged up and down and can rotate under the drive of the servo motor.

[0057] The first material receiving air expansion shaft 6 and the second material receiving air expansion shaft 8 adopt well-known air expansion shafts. After the high-pressure gas is introduced, the first material receiving air expansion shaft 6 and the second material receiving air expansion shaft 8 expand. After the gas is discharged, the first material receiving air expansion shaft 6 and the second material receiving air expansion shaft 8 contract.

[0058] The cut multiple strips of label paper are respectively wound around the first receiving air-inflating shaft 6 and the second receiving air-inflating shaft 8. The first receiving air-inflating shaft 6 and the second receiving air-inflating shaft 8 are driven by the servo motor to rotate to reel up the label paper.
