[0022] Specifically, the conductive layer is formed by vulcanizing the heated copper foil, the conductive layer and the heating plate 20 are an integrated structure, that is, the heated copper foil and the heating plate 20 are vulcanized into one, so as to form a conductive layer on the inner surface of the heating plate 20.

[0023] In one embodiment, the shell assembly 10 comprises a shell 11, a spacing portion 12 connected to the inner side of the shell 11, and an exhaust portion 13 connected to the outer side of the shell 11, the DTF printing film 40 generates smoke after being heated, and the smoke passes through the spacing portion 12 and is discharged from the exhaust portion 13.

[0024] Specifically, by providing a spacing portion 12 inside the shell 11 and an exhaust portion 13 outside the shell 11, the smoke first passes through the spacing portion 12 and then is discharged by the exhaust portion 13. The smoke is filtered by the exhaust portion 13 and then discharged, which reduces the possibility of environmental pollution. In addition, the smoke first enters the spacing portion 12, thereby preventing the smoke from overflowing along the air inlet 30 on both sides of the shell 11.

[0025] The shell assembly 10 forms a housing when connected to the heating plate 20 which protects the inner components of the DTF powder shaking machine. The air inlet 30 is formed by a space between the shell assembly 10 and the heating plate 20 to enable the ingress of air therethrough.

In the present disclosure, the smoke passes through the opening 1211, the spaced area 123 and the filter plate 132 in sequence and is then exhausted by the exhaust fan 131. The smoke circulates in the spaced area 123 and is then extracted and exhausted. In this way, the smoking will not lose heat, causing the temperature below the smoke baffle 121 to drop, thereby effectively ensuring the baking effect. [0033] Preferably, the smoke baffle 121 and the spacing plate 122 are connected by screws or snap-fitting.

[0034] In one embodiment, the outer side of the spacing plate 122 is provided with a conduit 124 connected to the spaced area 123, the filter plate 132 is connected to the conduit 124.

[0035] Specifically, the shell 11 is provided with an opening hole corresponding to the conduit 124. The smoke enters the conduit 124 from the airtight area 123 and then enters the filter plate 132 along the opening hole. The smoke flows stably and efficiently without overflow.

[0036] In one embodiment, a sealing member is provided between the smoke baffle 121 plate and the spacing plate 122.
