Description

Technical Field

[0001] The present application relates to the field of tire manufacturing, and in particular to a method and device for marking abnormal electron irradiation dose of tire fiber cord, which ensures the stability of electron irradiation dose and improves product consistency. Background Art

[0002] With the continuous innovation and progress of tire processing technology, electron irradiation technology is increasingly used in the tire manufacturing process. The commonly used process is electron irradiation of the inner liner of all-steel radial tires and electron irradiation of the fiber cord layer of semi-steel radial tires. The Chinese invention patent application (publication number: CN109291339A) applied by the applicant discloses a method for changing the performance of rubber-coated cord by electron irradiation. The method includes the following steps: the fiber cord enters the electron irradiation area of ​​the double-window electron irradiation device, wherein the parameters of the double-window electron irradiation device are voltage 500KV, dose 40KGY, and irradiation dose fluctuation <5%. The stability of electron irradiation parameters directly affects the quality of tire fiber cord. For tire fiber cord irradiation dose abnormalities caused by special reasons, it is necessary to mark the tire fiber cord, which is conducive to the subsequent isolation of abnormal tire fiber cords. Summary of the invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this application is to provide a device for marking abnormal electron irradiation dose of tire fiber cord. For abnormal tire fiber cord irradiation dose caused by special reasons, the tire fiber cord needs to be marked, which is conducive to the subsequent isolation and treatment of the abnormal tire fiber cord, ensuring the stability of the electron irradiation dose and improving product consistency.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] A device for marking anomalies in the electronic irradiation dose of a tire fiber cord comprises an anomaly collection module, a host control module and an anomaly marking module. The anomaly collection module collects the electronic irradiation dose in the host control module and compares it with a normal set value. When an abnormality occurs in the electronic irradiation dose, a control signal is output to the host control module to adjust the electronic irradiation dose. At the same time, the host control module controls the anomaly marking module to mark the tire fiber cord.

[0006] As a further improvement, the abnormal marking module adopts an inkjet device, which includes a mounting plate, a driving cylinder and an inkjet head. The mounting plate is horizontally arranged above the tire fiber cord, and the driving cylinder is fixedly arranged on the mounting plate. A horizontal slide rail is arranged on the mounting plate, and a slider is arranged on the slide rail. The slider is connected to the piston rod of the driving cylinder, and a U-shaped plate is arranged on the slider. The recess of the U-shaped plate is arranged opposite to one side of the tire fiber cord, and inkjet heads are respectively arranged above and below the recess, and the inkjet heads are connected to the ink cartridge; the extension and retraction of the piston rod of the driving cylinder respectively makes the inkjet head correspond to the preparation station and the working station, the preparation station is located outside one side of the tire fiber cord, and the working station is located on the upper part of one side of the tire fiber cord.

[0007] As a further improvement, the upper and lower inkjet heads are staggered.

[0008] As a further improvement, the host control module includes a timer, which controls the upper and lower inkjet heads to spray ink into the air at intervals of 1 hour. Ink is easy to condense under high temperature operation, so this application designs a regular self-cleaning function of the inkjet device, that is, the inkjet device withdraws from the working station to the preparation station to spray ink into the air every 1 hour to ensure the smooth operation of the device.

[0009] The present application also discloses a method for marking abnormal electron irradiation dose of tire fiber cords. The method collects the electron irradiation dose in the host control module through an abnormal acquisition module and compares it with a normal set value. When an abnormal electron irradiation dose occurs, a control signal is output to the host control module to adjust the electron irradiation dose. At the same time, the host control module controls the abnormal marking module to mark the tire fiber cord.

[0010] As a further improvement, the abnormal marking module adopts an inkjet device, which sprays ink on both sides and marks the tire fiber cord with white ink at a spraying interval of 50mm.

[0011] As a further improvement, the upper and lower inkjet heads of the inkjet device are staggered, and the upper and lower inkjet heads are controlled to spray ink into the air at intervals of one hour.

[0012] Since the present application adopts the above-mentioned technical solution, the tire fiber cord needs to be marked for abnormal radiation dose of the tire fiber cord caused by special reasons, which is conducive to the subsequent isolation treatment of the abnormal tire fiber cord, ensures the stability of the electron radiation dose, and improves product consistency.

[0021] The stability of electron irradiation parameters directly affects the quality of the tire fiber cord 10. For abnormal irradiation dose of the tire fiber cord 10 caused by special reasons, the tire fiber cord 10 needs to be marked to facilitate subsequent isolation of the abnormal tire fiber cord 10.

The abnormality collection module collects the electron irradiation dose in the host control module and compares it with the normal set value. When the electron irradiation dose is abnormal, the control signal is output to the host control module to adjust the electron irradiation dose. At the same time, the host control module controls the abnormality marking module to mark the tire fiber cord 10. The information processing flow is as follows Figure 3 .

[0023] like Figure 2As shown, the abnormal marking module adopts an inkjet device, which includes a mounting plate 1, a driving cylinder 2 and an inkjet head 6. The mounting plate 1 is horizontally arranged above the tire fiber cord 10, and the driving cylinder 2 is fixedly arranged on the mounting plate 1. The mounting plate 1 is provided with a horizontal slide rail 2, and the slide rail 2 is provided with a slider 3. The slider 3 is connected to the piston rod of the driving cylinder 2. A U-shaped plate 4 is arranged on the slider 3, and the notch of the U-shaped plate 4 is arranged directly opposite to one side of the tire fiber cord 10. The inkjet heads 6 are arranged above and below the notch, respectively, and the upper and lower inkjet heads 6 are arranged in a staggered manner. The inkjet head 6 is connected to the ink cartridge; the extension and retraction of the piston rod of the driving cylinder 2 respectively make the inkjet head 6 correspond to the preparation station and the working station, the preparation station is located outside one side of the tire fiber cord 10, and the working station is located at the upper part of one side of the tire fiber cord 10.

[0024] In addition, the control module of the present application includes a timer, which controls the upper and lower inkjet heads 6 to spray ink into the air at intervals of 1 hour. Ink is easy to condense under high temperature operation, so the present application designs a regular self-cleaning function of the inkjet device, that is, the inkjet device withdraws from the working station to the preparation station to spray ink into the air at intervals of 1 hour to ensure the smooth flow of the device.
