Description

Technical Field

[0001] This application relates to the field of scale printing mechanisms, and in particular, to a printing mechanism for printing scales on a hot water kettle. Background Art

[0002] A hot water kettle can not only keep hot water warm but also heat water, and it is a common household item in life. Almost every household has a hot water kettle. Among them, a glass hot water kettle is also one of many types of hot water kettles. The glass hot water kettle includes a kettle body and a base connected to the bottom of the kettle body, and the kettle body has openings at both ends. To help users accurately control the water level and ensure safe use, producers often print scale lines on the kettle body of the glass hot water kettle to increase the convenience of using the hot water kettle. In the existing methods for printing scales on the kettle body, laser engraving is mostly used. Laser engraving is to use a laser beam to burn the surface of the kettle body to form characters or patterns. A laser printing machine is required for laser engraving, and the purchase price of this type of machine is expensive, resulting in a relatively high production cost of the product. In view of the above related technologies, the inventor believes that a printing mechanism for printing scales on a hot water kettle with an ideal production cost is needed. Utility Model Content

[0006] By adopting the above technical solutions, through the cooperation between the first rotating frame and the bottom of the kettle body and the cooperation between the second rotating frame and the top of the kettle body driven by the driving mechanism, the locking of the kettle body between the first rotating frame and the second rotating frame is completed. The printing plate is used to print scales on the surface of the kettle body, and then the first driving member drives the rotation of the first rotating seat, thereby driving the synchronous rotation of the second rotating seat, and thus completing the scale printing on both sides of the kettle body. The method of printing scales on the surface of the kettle body by screen printing helps to reduce the production cost of printing scales on the hot water kettle compared with laser engraving.

[0007] Optionally, the frame is provided with a fixing bracket for the printing board to be arranged in an up-and-down flipping manner.

[0008] By adopting the above technical solution, when the printing board is flipped upwards, it is helpful for the installation of the kettle body between the first rotating seat and the second rotating seat; when the printing board is flipped downwards, the printing board is located above the kettle body, which is helpful for the scale printing on the surface of the kettle body.

At this time, the upper opening of the contact part between the top of the kettle body and the rubber strip is larger, which helps the operator to disassemble and install the kettle body.

[0019] Optionally, the driving mechanism includes a guide rod parallel to the height direction of the kettle body, a guide sleeve installed on the second rotating frame and cooperating with the guide rod, and a driving cylinder installed on the machine frame; the piston rod of the driving cylinder is parallel to the guide rod and is connected to the side of the second rotating frame facing away from the first rotating frame.

[0020] By adopting the above technical solution, the structure of the driving mechanism is disclosed.
