The above structure is the prior art of the film coating machine, and the working principle and specific structure will not be described here.

[0030] Please refer to Figure 1 , Figure 3 and Figure 4On both sides of the conveyor belt A100, there are "I"-shaped sliding columns 12 fixedly connected to the baffles. "I"-shaped sliders 11 are slidably connected to the "I"-shaped sliding columns 12. A connecting rod 10 is fixedly connected to the top surface of the "I"-shaped slider 11. A limit stop 9 is fixedly connected to one end of the connecting rod 10. An "L"-shaped fixing rod 8 is fixedly connected to one side of the limit stop 9. A hinge frame 6 is installed on the top of the "L"-shaped fixing rod 8. The hinge frame 6 consists of a fixing frame 60 and a fixing shaft 61. An "L"-shaped frame 2 is fixedly installed on one side of the conveyor belt A100. A sliding column 3 is vertically installed on the "L"-shaped frame 2.

A positioning bolt 5 is threadedly connected to one side of the slider 4, and the positioning bolt 5 abuts against one side of the sliding column 3. On the side, the operator loosens the positioning bolt 5, at which point the slider 4 can slide up and down on the sliding column 3. According to the length of the foam base, it is adapted to the appropriate length of the foam base according to the marking of the scale value 30. For example, if the length of the foam base is 30 cm, the scale value 30 will be marked with the corresponding scale value. The operator only needs to hold the handle 40 and push the slider 4 to the corresponding value of the scale value 30, and then tighten the positioning bolt 5 to hold the sliding column 3 to prevent it from falling. As the slider 4 moves upward, the connecting rod 7 will be lifted upward. At the same time, the connecting rod 7 will drive the "L"-shaped fixing rod 8 and the limit stop rod 9 to move closer to the center. The limit stop rod 9 is restricted by the connecting rod 10 and the "I"-shaped slider 11. At this time, the "I"-shaped slider 11 can only slide horizontally in the "I"-shaped sliding groove column 12.

[0031] Please see Figure 1 and Figure 5 A connecting frame 13 is fixedly connected to one side of the "U"-shaped frame 103. A suction fan 14 is installed on the connecting frame 13. The suction fan 14 is connected to an external power supply. A threaded hole 170 is opened at the end of the air outlet pipe 17. The outer circumference of the HEPA filter 18 is engraved with external threads. The external threads of the HEPA filter 18 are connected to the threaded hole 170. Multiple hand-twist rings 180 are fixedly connected to the outer ring of the HEPA filter 18. The air inlet plate 16 is installed on one side of the membrane. After the suction fan 14 is turned on, the suction fan 14 will suck the dust on the membrane into the air inlet plate 16 and flow into the suction fan 14 from the air inlet pipe 15. Then it flows out from the air outlet pipe 17 and finally the dust particles are adsorbed by the HEPA filter 18. By twisting the hand-twist ring 180, the HEPA filter 18 is disengaged from the threaded hole 170, which makes it convenient for users to clean the dust on the HEPA filter 18. Here, dust refers to residues in the membrane production process, pollutants in the production environment, and impurities generated by contact with equipment.

[0032] The implementation principle of a foam base laminating machine for household appliances according to an embodiment of this application is as follows:

[0033] The operator loosens the positioning bolt 5, at which point the slider 4 can slide up and down on the sliding column 3. According to the length of the foam base, it is adapted to the appropriate length of the foam base according to the marking of the scale value 30. For example, if the length of the foam base is 30 cm, the scale value 30 will be marked with the corresponding scale value. The operator only needs to hold the handle 40 and push the slider 4 to the corresponding value of the scale value 30, and then tighten the positioning bolt 5 to hold the sliding column 3 to prevent it from falling.

[0034] As the slider 4 moves upward, the connecting rod 7 will be lifted upward. At the same time, the connecting rod 7 will drive the "L"-shaped fixed rod 8 and the limiting stop 9 to move closer to the center. The limiting stop 9 is restricted by the connecting rod 10 and the "I"-shaped slider 11. At this time, the "I"-shaped slider 11 can only slide horizontally in the "I"-shaped sliding groove column 12.

[0035] After the suction fan 14 is turned on, the suction fan 14 will suck the dust on the membrane into the air inlet plate 16 and flow into the suction fan 14 from the air inlet pipe 15. Then it will flow out from the air outlet pipe 17 and finally the dust particles will be adsorbed by the HEPA filter 18. By turning the hand ring 180, the HEPA filter 18 can be disengaged from the threaded hole 170, which makes it convenient for the user to clean the dust on the HEPA filter 18.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
