Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior decoration production, in particular to an automobile interior decoration pad printing device. Background Art

[0002] Car interior mainly refers to the car products used for car interior modification, involving all aspects of the car interior, such as car steering wheel covers, car seat cushions, car floor mats, car perfumes, car pendants, interior ornaments, storage boxes, etc. are all car interior products.

[0003] In the production process of automobile interior trim strips, a pad printing device is usually required. It uses a steel (or copper, thermoplastic plastic) gravure and a curved pad printing head made of silicone rubber material. The ink on the gravure is dipped onto the surface of the pad printing head, and then pressed on the surface of the interior trim strip to print text, patterns, etc.

[0004] However, most existing pad printing devices have complex structures. After adding ink to the character groove, an additional scraper needs to be operated to scrape off the excess ink, which is troublesome and inefficient. In addition, the ink is often placed in an open manner, which easily causes the ink to evaporate and dry, resulting in ink waste and increasing the cost of using the device. Therefore, in view of the above technical problems, a pad printing device for automotive interior is proposed. Utility Model Content

[0008] The ink filling assembly includes an ink cartridge, which is connected to the guide seat. An ink storage groove is provided at the bottom of the ink cartridge. The ink storage groove is sealed and connected to the top surface of the pad printing plate. When the pad printing rubber head is located above the positioning seat or the character groove, the ink storage groove is connected or misaligned with the character groove.

[0009] The beneficial effects of the above-mentioned interior trim pad printing device are:

[0010] The first telescopic rod is controlled to telescope and drive the pad printing rubber head and the ink cartridge to move synchronously. When the pad printing rubber head moves to above the positioning seat to print the interior trim, the ink cartridge moves to connect the ink storage slot with the character slot. At this time, the ink in the ink storage slot can enter the character slot, thereby performing an ink adding operation. When the pad printing rubber head moves in the opposite direction to above the character slot, the ink cartridge moves in the opposite direction to dislocate the ink storage slot with the character slot. The dislocation of the ink storage slot with the character slot can stop adding ink to the character slot and cooperate with the top surface of the pad printing plate to scrape off excess ink, thereby eliminating the need to operate an additional scraper to scrape off excess ink. The operation is simple and efficient. The ink is stored in the ink storage slot. During the process of connecting with the character slot to add ink or dislocating to scrape off excess ink, the ink storage slot and the top surface of the pad printing plate always maintain a sealed connection, thereby keeping the ink in a sealed state at all times, making it difficult for the ink to evaporate and dry, thereby avoiding ink waste and reducing the use cost of the device.
