Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to an air handling mechanism for a film cutting machine. Background Art

[0002] As the speed of updating and replacing mobile phones and electronic products continues to accelerate, many film merchants and mobile phone chain stores have now purchased film cutting machines and used automated machinery and equipment to cut films. Film cutting machines can quickly cut out mobile phone films that match electronic products, reducing the pressure of stockpiling and accumulation of goods for film merchants and greatly improving the efficiency of film pasting.

[0003] There is no very accurate answer to the question of whether laser or blade film cutting machines are better. The choice of which film cutting machine should be determined based on actual needs. Both methods have different advantages and characteristics.

[0004] The main advantage of laser film cutting machine over knife head film cutting machine is that it can cut most of the harder materials on the market, has strong penetrating power, and can cut very thick and hard mobile phone films. The principle of laser film cutting machine is to focus the laser into a high-power density laser beam, so that the laser beam is irradiated on the material to be cut, thereby achieving the purpose of cutting, which is incomparable to knife head film cutting machine. However, laser film cutting machine will produce a lot of smoke and pungent smell during operation, which has a greater impact on the environment.

[0046] The control device 41 includes a head support shaft 47, a vertical support shaft 48, a tail gear 49, a sub-plate frame 52 and a disc gear 54. One end of the head support shaft 47 is coaxially arranged with the side shaft 22, and the tail gear 49 is fixed on the side shaft 22. The other end of the head support shaft 47 is meshed and connected with the bevel gear fixed at one end of the vertical support shaft 48 through a fixed bevel gear.

[0048] One end of the main shaft 16 is connected to the second motor provided in the film cutting machine body 1. The rotation of the main shaft 16 drives a row of activated carbon cartridges 30 to rotate, specifically drives the small ring gear 27 to rotate, and then drives the activated carbon cartridges 30 to rotate through the outer ring gear 29. Figure 8The activated carbon cartridge 30 in the rotating tube 5 rotates continuously, and the fan 11 rotates for ventilation at the same time. The smoke in the rotating tube 5 passes through the inner cavity of the wind barrel 12 and is discharged into the rough pipe 19, and then is injected into the inner cavity of the inner half shell 32, and then is discharged outward after passing through the partial shell of the activated carbon cartridge 30. The activated carbon cartridge 30 is a smoke odor filtering material in the prior art. The pressure spring 31 provides elastic force for the rotation of the outer half shell 33. The outer half shell 33 buffers the smoke pressure injected into the inner cavity of the inner half shell 32 by swinging. The activated carbon cartridge 30 rotates continuously to evenly absorb smoke odor and dust. As the air filtration time increases, the micropores in the shell of the activated carbon cartridge 30 are gradually blocked by impurities, and the air permeability decreases, so that the air pressure in the inner half shell 32 rises, and the outer half shell 33 swings outward at a larger angle. If the outward swing is too large, it will trigger the subsequent update mechanism. Specifically, the swing of the outer half shell 33 causes the rotation of the inner shaft 15. The rotation of the inner shaft 15 in the fan shaft 13 drives the pendulum body 44. After the convex plate of the pendulum body 44 swings to the end, it will contact and push the L-shaped push frame 42. The L-shaped push frame 42 drives the waist shaft 51, and then the waist gear 50 moves axially and contacts and meshes with the tail gear 49.

[0049] During the rotation of the main shaft 16, the disc gear 54 is driven by the worm, and then the vertical support shaft 48 transmits the head support shaft 47, causing the waist gear 50 to rotate continuously. After the rotating waist gear 50 docks with the tail gear 49, the side shaft 22 is caused to rotate continuously. Next, the boost shaft 40 rotates to cause the travel spring 39 to contract. The travel spring 39 provides pressure to the travel ring cylinder 38. After the power is saturated, the boost shaft 40 continues to rotate, and the travel ring cylinder 38 will rotate and break through the blocking position of the card plate 36. The next time the card plate 36 encounters the groove on the travel ring cylinder 38, it will be inserted smoothly. During this process, The travel ring cylinder 38 just rotates one circle, and drives the U-shaped column 17 to translate a fixed distance through the outer gear ring. This distance is the spacing between two adjacent activated carbon cylinders 30. The U-shaped column 17 drives all the purification units 18 to move synchronously, so that the activated carbon cylinder 30 blocked by flue gas impurities is separated from the exhaust head 20 after axial movement, and the new activated carbon cylinder 30 is re-put on the exhaust head 20, completing the update of the activated carbon cylinder 30, and the flue gas filtration work returns to normal, the flue gas in the inner half shell 32 can be quickly discharged through the activated carbon cylinder 30, and the outer half shell 33 no longer swings excessively, and the subsequent update mechanism ends automatically.
