For example, in the present embodiment, the number of lifting stampers is 2, and two lifting stampers form a gap, and the aluminum material to be spray-stamped is arranged between the two lifting stampers.

[0029] From a structural point of view, Figure 1-Figure 2As shown, the lifting stamping device of this embodiment includes a support frame 1, and the support frame 1 includes a crossbeam and longitudinal beams arranged at both ends of the crossbeam. A pressure roller 2 that rotates on the support frame 1 is installed on the support frame 1. Specifically, a driving motor 6 is installed on the support frame 1, and the driving motor 6 is fixedly installed on the support frame 1 by bolts. A driving wheel 7 is installed on the output shaft of the driving motor 6. A connecting shaft is installed at the end of the pressure roller 2, and the connecting shaft is inserted in the bearing of the bearing seat 4. The bearing seat 4 is arranged at the end of the longitudinal beam, and a connecting shaft protrudes from the bearing seat 4. The outer periphery of the connecting shaft passes through the inner periphery of the bearing in the bearing seat 4. The driven wheel 5 is installed on the connecting shaft protruding from the bearing seat 4 with an interference fit, and the driving wheel 7 and the driven wheel 5 are connected together in transmission. For example, the driving wheel 7 and the driven wheel 5 in this embodiment are pulleys, and a transmission belt 8 is wound around the driving wheel 7 and the driven wheel 5. The pressure roller 2 is driven by the driving motor 6 to rotate. In order to reduce the weight of the pressure roller 2 and reduce the difficulty of lifting and rotating the pressure roller 2, the pressure roller 2 in this embodiment includes a cylinder body, which is a cylindrical structure with a circular cross-section. The side of the cylinder body is provided with a side plate, and the side plate is provided with a through groove. The connecting shaft is fixedly connected to the side plate, so that the pressure roller 2 has a hollow structure, which reduces the weight of the pressure roller 2.

[0030] In this embodiment, a wood grain layer 3 is arranged on the surface of the pressure roller 2. The wood grain layer 3 is a plurality of striped groove structures. A spray barrel 9 is installed above the pressure roller 2. The spray barrel 9 has a closed end and an open end. The open end of the spray barrel 9 is connected to the paint tank through a delivery hose 10. The pump body on the delivery hose 10 draws the paint in the paint tank into the spray barrel 9 along the delivery hose 10. A paint delivery hole is opened on the spray barrel 9, and the paint delivery hole is aligned with the wood grain layer 3 on the pressure roller 2. In this embodiment, the paint in the paint tank is delivered to the spray barrel 9 by a pump, and the paint is delivered to the wood grain layer 3 on the pressure roller 2 along the paint delivery hole of the spray barrel 9.
