[0038] like Figure 1 , Figure 2 , Figure 4 As shown, Figure 1 What is shown is the overall schematic diagram of the oil supply device in the embodiment; Figure 2 What is shown is a cross-sectional schematic diagram of the oil supply device in the embodiment; Figure 4 Shown is a cross-sectional schematic diagram of a sealed vent plate in an embodiment;

[0039] The device includes:

[0040] An oil storage tank 10 with an opening at the top and a heating element 11 at the bottom of the oil storage tank 10;

[0041] A sealing vent plate 20, the sealing vent plate 20 is sealingly covered on the top of the oil storage tank 10;

[0042] and an oil return chamber 30, the oil return chamber 30 is movably and symmetrically arranged on both sides of the top of the oil storage chamber 10, the gap between the oil return chambers 30 forms an oil injection area 40 for gaseous oil to pass through, and the oil return chamber 30 moves in the horizontal direction so that the gap size of the oil injection area 40 can be changed;

[0043] The top of the oil return chamber 30 is open, and the returned oil enters the chamber body from the top of the oil return chamber 30 .

[0044] The heating element 11 is a heater, which heats the oil inside the oil storage tank 10 until it evaporates. When the oil is heated into a gaseous state, the sealing ventilation plate 20 is covered on the top of the oil storage tank 10, and the gaseous oil passes through the sealing ventilation plate 20 and the spraying area 40, and is finally sprayed onto the metallized film.

[0045] By setting the oil return bins 30 on both sides of the top of the oil storage bin 10, the falling oil will flow into the oil return bins 30 on both sides for temporary storage, so that the oil can be recycled and resources can be saved; and the gaps between the oil return bins 30 correspond to the positions of the sealing ventilation plates 20 and are connected to the sealing ventilation plates 20 to form a channel for the flow of gaseous oil. The movably arranged oil return bins 30 make the range of gaseous oil spraying adjustable, that is, the size of the spraying area 40 is adjustable, so that the gaseous oil spraying range can be adjusted according to the size of the substrate, which can adapt to production tasks of different specifications or different requirements, and the same equipment can process substrates of multiple different specifications, thereby improving the utilization rate of the equipment.

[0046] like Figure 1 , Figure 2 , Figure 5 As shown, Figure 1 What is shown is the overall schematic diagram of the oil supply device in the embodiment; Figure 2 What is shown is a cross-sectional schematic diagram of the oil supply device in the embodiment; Figure 5 It shows Figure 2 A magnified schematic diagram of the structure at center A;

[0047] A sealing ring 1 51 is fixedly provided on the inner side of the top opening of the oil storage bin 10 , and sealing rings 2 52 are provided on both sides of the top of the sealing ventilation plate 20 . When the sealing ventilation plate 20 covers the open end of the oil storage bin 10 , the bottom of the oil reflux bin 30 contacts and presses the sealing ring 2 52 .

[0048] By providing the sealing ring 1 51 and the sealing ring 2 52 , after the sealing vent plate 20 covers the top opening of the oil storage bin 10 , the sealing effect of the sealing vent plate 20 is improved.

[0049] Before the sealing vent plate 20 is installed, the oil reflux bins 30 are far away from each other and are in a position that does not affect the installation of the sealing vent plate 20. After the sealing vent plate 20 is installed, the oil reflux bins 30 are close to each other, and the bottom of the oil reflux bin 30 is in conflict with the sealing ring 2 52. At this time, the bottom of the oil reflux bin 30 presses the sealing ring 2 52, and when the size of the injection area 40 is subsequently adjusted, when the oil reflux bin 30 moves horizontally within a certain range to change its position, the bottom of the oil reflux bin 30 is always in a state of conflict with the sealing ring 2 52.

[0050] The oil reflux chamber 30 can press the two sides of the sealing vent plate 20 , which can fix the sealing vent plate 20 on the one hand, and can improve the sealing effect of the sealing vent plate 20 in combination with the sealing ring 1 51 and the sealing ring 2 52 on the other hand.

[0051] like Figure 3 , Figure 4 As shown, Figure 3 Shown is an overall schematic diagram of a sealed vent plate in an embodiment; Figure 4 Shown is a cross-sectional schematic diagram of a sealed vent plate in an embodiment;

[0052] The top of the sealing ventilation plate 20 is evenly provided with multiple convex surfaces 21 and multiple concave surfaces 22. A ventilation hole is opened at the center of the convex surface 21, and a one-way diaphragm 23 is arranged in the ventilation hole; a reflux hole 24 is opened at the center of the concave surface 22, and an electromagnetic control valve is arranged in the reflux hole 24.

[0053] The vent holes and the one-way diaphragm 23 of the convex surface 21 allow gaseous oil to pass through, and the concave surface 22 and the reflux hole 24 can also play a role in recovering oil. Through the electromagnetic control valve, the recovered oil can re-enter the oil storage tank 10 in the non-working state.

[0054] like Figure 2 , Figure 6 As shown, Figure 2 What is shown is a cross-sectional schematic diagram of the oil supply device in the embodiment; Figure 6 It shows Figure 2 A partial enlarged schematic diagram of the oil return chamber;

[0055] The top opening end of the oil return chamber 30 is funnel-shaped;

[0056] A reflux pipe 32 is also provided at the bottom of the oil reflux bin 30 , one end of the reflux pipe 32 is connected to the inside of the oil reflux bin 30 through a second reflux hole 31 , and the other end of the reflux pipe 32 is connected to the oil storage bin 10 , and an electromagnetic control valve is provided in the second reflux hole 31 .

[0057] The funnel-shaped opening end facilitates the diversion of the falling oil so that it can smoothly enter the oil return bin 30 , and the return pipe 32 facilitates the introduction of the recovered oil into the oil storage bin 10 .

[0061] An elastic stop block 70 is also disposed on the top of the oil return chamber 30 , and the elastic stop block 70 locks the embedded filter screen 60 in the open end of the oil return chamber 30 .

[0062] The filter screen 60 can be provided to filter the oil falling back into the oil return chamber 30 , thereby removing the external impurities in the falling oil and the impurities entrained in the falling oil.

[0065] The elastic limit block 70 can fix the installed filter 60; specifically, when installing the filter 60, the two sides of the filter 60 squeeze the block 72, so that the block 72 compresses the spring 73 and enters the fixed frame 71, and the filter 60 can be smoothly embedded and installed. After embedding, the filter 60 is located below the block 72. The block 72 is reset under the action of the spring 73, and extends out to limit the filter 60 from moving upward and leaving the oil reflux chamber 30.
