Description

Technical Field

[0001] This utility model relates to the field of household appliance manufacturing equipment technology, and more specifically, to a hot stamping device for the door of a drum washing machine. Background Technology

[0002] As a mainstream appliance in modern households, the appearance design of drum washing machines, especially the decorative aspect of the door frame, directly affects the product's premium pricing power. Hot stamping, due to its strong metallic texture and good wear resistance, is widely used in the processing of washing machine door frames and decorative strips to meet the aesthetic demands of the high-end market.

[0003] Based on the above, the inventors have discovered that in the hot stamping process of drum washing machine doors, most methods rely on workers manually aligning the hot stamping mold with the curved surface of the door ring and pressing it together. However, during the process, manual alignment is prone to misalignment, resulting in misalignment of the hot stamping pattern, poor positioning accuracy, and impacting product quality and efficiency. Furthermore, manual operation usually requires close contact with the high-temperature hot stamping plate, which can easily cause burns and poses a significant safety hazard. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a hot stamping device for drum washing machine doors, aiming to achieve greater practical value.

It can automatically load and unload hot stamping materials by using an unwinding mechanism, a winding mechanism, and multiple tension rollers. The lifting cylinder can control the hot stamping mechanism, causing the heated hot stamping pressure roller to move down and press the hot stamping material onto the drum washing machine door ring. Under the action of the drive motor, rotating shaft, and positioning seat, the drum washing machine door ring rotates, thus realizing the automatic hot stamping operation of the drum washing machine door ring, greatly improving the overall processing efficiency and operational safety.

A rocker plate 204 is fixedly connected to the top end of the lead screw 203.

[0043] See Figure 1 The unwinding mechanism 6 includes an unwinding roller 601 fixed to one end of the mounting frame 5, an unwinding motor 602 mounted on one side of the mounting frame 5, a feeding roller 603 rotating at one end of the mounting frame 5, and a limiting roller 604. The unwinding roller 601 is located above the limiting roller 604. The feeding roller 603 and the limiting roller 604 are arranged in parallel and a gap is provided between them. The output shaft of the unwinding motor 602 is connected to one end of the feeding roller 603 through a coupling.

[0044] See Figure 1The winding mechanism 7 includes a take-up roller 701 that rotates at the other end of the mounting frame 5 and a take-up motor 702 mounted on the side of the other end of the mounting frame 5. The output shaft of the take-up motor 702 is connected to one end of the take-up roller 701 via a coupling.

[0045] See Figure 4 The hot stamping mechanism 9 includes a protective cover 901 fixed to the bottom of the connecting seat 8. A heater 902 is installed on the inner wall of the protective cover 901.
