[0002] An imide furnace is a device for producing PI films. The PI film, also known as polyimide film, is formed by polycondensation of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in a strongly polar solvent, followed by casting into a film and then imidization.
[0003] During the production process of PI films, chain film clips are required to hold the PI films in an imide furnace at 500 °C and run on the tracks with the PI films clamped. However, currently, the tracks and chain film clips used for producing PI films lack dust-proof devices. When the equipment is in a shutdown state, dust is likely to accumulate after a long period of idling. The dust adhering to the tracks will affect the smooth movement of the chain film clips, and the affected smooth movement of the chain film clips may pull the films, thereby affecting the production of PI films.

[0023] As Figures 1 - 5 shown, the present utility model provides a technical solution: a track chain device with a dust-proof structure, including a track body 1, a chute 2 is opened on the track body 1, a top plate 3 is fixedly installed on the top of the track body 1, the inner wall of the chute 2 is slidably connected with a chain film clip 4, a protection mechanism 5 for blocking dust is arranged on the top plate 3. By setting the protection mechanism 5, the track body 1 can be protected when the track body 1 is idle, avoiding dust from falling into the inside of the chute 2 and affecting the sliding of the chain film clip 4. A lubrication mechanism 6 is arranged on the top plate 3. By setting the lubrication mechanism 6, lubricating oil can be added into the inside of the chute 2, reducing the friction between the chain film clip 4 and the chute 2, and further enabling the chain film clip 4 to slide more smoothly
[0024] The above protection mechanism 5 includes a boss 51, a worm gear 52, a worm 53, a rotating rod 54, a baffle 55, a knob 56; the boss 51 is fixedly installed on the side wall of the top plate 3, the inner wall of the boss 51 is rotatably connected with a rotating rod 54, a baffle 55 is fixedly installed on the outer wall of the rotating rod 54. By rotating the rotating rod 54, the baffle 55 can be driven to rotate upwards until the baffle 55 covers the top of the top plate 3. At this time, the baffle 55 can be used to block falling dust, avoiding dust from falling into the inside of the chute 2 and affecting the sliding of the chain film clip 4. The worm gear 52 is fixedly installed on the outer wall of the rotating rod 54, one end of the worm 53 is rotatably connected to the inner wall of the boss 51, the other end of the worm 53 penetrates through the boss 51 and is fixedly installed with a knob 56. The penetration part of the worm 53 and the boss 51 is rotatably connected, and the worm 53 meshes with the worm gear 52. By rotating the knob 56 to rotate the worm 53, the rotating rod 54 can be driven to rotate in the inner wall of the boss 51 through the rotation of the worm 53 and its meshing with the worm gear 52
[0025] The above lubrication mechanism 6 includes an oil sump 61, an oil pipe 62, a piston 63, a ball head rod 64, and a spring 65; the oil sump 61 is opened on the inner wall of the top plate 3, the outer wall of the top plate 3 is fixedly installed with the oil pipe 62, the inside of the oil pipe 62 is communicated with the inside of the oil sump 61, and lubricating oil can be dripped into the inside of the chute 2 through the oil pipe 62. By adding lubricating oil into the inside of the chute 2, the friction between the chain film clip 4 and the chute 2 can be reduced, and thus the chain film clip 4 can slide more smoothly. The inner wall of the oil sump 61 is slidably connected with the piston 63. By sliding the piston 63, the lubricating oil inside the oil sump 61 can be extruded through the oil pipe 62. A ball head rod 64 is fixedly installed on the side wall of the piston 63. When the ball head rod 64 slides into the inside of the oil sump 61, it will push the piston 63, causing the piston 63 to slide on the inner wall of the oil sump 61 and stretch the spring 65. One end of the ball head rod 64 away from the piston 63 penetrates through the top plate 3, and the penetration part of the ball head rod 64 and the top plate 3 is slidably connected. During the process of the rotating rod 54 driving the baffle 55 to rotate upward, when the baffle 55 contacts the ball head rod 64, it will squeeze the ball head rod 64, causing the ball head rod 64 to slide into the inside of the oil sump 61. A spring 65 is sleeved on the outer wall of the ball head rod 64. One end of the spring 65 is fixedly installed on the inner wall of the oil sump 61, and the other end of the spring 65 is fixedly installed on the outer wall of the piston 63. When the baffle 55 disengages from squeezing the ball head rod 64, the elastic force of the spring 65 can drive the piston 63 to slide back to its original position.
[0026] Working principle: When the track body 1 is idle, rotate the worm 53 through the knob 56. By the rotation of the worm 53 and its meshing with the worm wheel 52, the rotating rod 54 can be driven to rotate on the inner wall of the boss 51. By the rotation of the rotating rod 54, the baffle 55 can be driven to rotate upward until the baffle 55 covers the top of the top plate 3. At this time, the baffle 55 can be used to block dust from falling, avoiding dust from falling into the inside of the chute 2 and affecting the sliding of the chain film clip 4.
[0027] During the process of the rotating rod 54 driving the baffle 55 to rotate upward, when the baffle 55 contacts the ball head rod 64, it will squeeze the ball head rod 64, causing the ball head rod 64 to slide into the inside of the oil sump 61. At the same time, the ball head rod 64 will push the piston 63, causing the piston 63 to slide on the inner wall of the oil sump 61 and stretch the spring 65. At this time, by sliding the piston 63, the lubricating oil inside the oil sump 61 can be extruded through the oil pipe 62, so that the lubricating oil drips into the inside of the chute 2. By adding lubricating oil into the inside of the chute 2, the friction between the chain film clip 4 and the chute 2 can be reduced, and thus the chain film clip 4 can slide more smoothly.
[0028] Generally speaking, the above has described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, any modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
