The end of the connecting pipe 329 away from the dust collecting box 328 is connected to the second one-way air intake valve 325, and the first one-way air intake valve 323 is connected to the connecting pipe 329 through a hose.

[0063] By providing the dust suction pipe 326, the three-way pipe 327 and the dust collecting box 328, it is convenient to absorb the dust on the surface of the film and remove the dust from the film.

[0064] The inner cavity of the dust box 328 is provided with a collecting frame 330, the bottom of the collecting frame 330 is inlaid with a mesh plate, the bottom of the collecting frame 330 is connected to a balance plate, the balance plate is connected to the inner wall of the dust box 328, one side of the collecting frame 330 passes through the outside of the dust box 328, the surface of the collecting frame 330 is connected to a handle, and the opposite side of the U-shaped plate 30 is connected to a second support roller 331.

[0065] The collecting frame 330 and the screen plate facilitate dust collection and dumping. The balancing plate is provided to support the collecting frame 330. The handle is provided to facilitate disassembly of the collecting frame 330. The second supporting roller 331 is provided to support the film and facilitate the transportation of the film.

[0066] The use process of a plastic film processing and forming device provided by the present invention is as follows:

[0067] S1. Cooling: After being blow-molded by the blow molding machine, the film passes through the elliptical tube 31 and the tensioning tube 315, the upper and lower second support rollers 331, and the upper and lower dust suction tubes 326 in sequence. The one-way liquid inlet valve 37 is connected to the external cooling box through a pipeline, and the second vertical plate 38 is driven to move horizontally by controlling the linear motor 310 to operate. The second vertical plate 38 drives the one-way liquid inlet valve 37, the one-way liquid outlet valve 36 and the piston plate 35 to move horizontally. When the one-way liquid inlet valve 37 drives the piston plate 35 away from the partition 34, the pressure in the inner cavity of the driving tube 32 is reduced, so that the one-way liquid inlet valve 37 is opened, and the liquid in the cooling box cavity enters the inner cavity of the driving tube 32 through the one-way liquid inlet valve 37, and the cooling is performed. The liquid enters the inner cavity of the elliptical tube 31 through the leaking hole 33. The elliptical tube 31 is in close contact with the film, absorbs the heat on the surface of the film, and cools the film. When the piston plate 35 is close to the partition plate 34, the pressure in the inner cavity of the driving tube 32 increases, so that the one-way liquid outlet valve 36 is opened. The cooling liquid in the inner cavity of the elliptical tube 31 passes through the leaking hole 33, the driving tube 32, the one-way liquid outlet valve 36, the left collecting box 332, the short tube 316, the tensioning tube 315, and the right collecting box 332 in sequence, and finally flows to the inner cavity of the cooling box through the return pipe 322. The cycle is repeated, and the tensioning tube 315 absorbs the heat at the bottom of the film, so that the coolant flows continuously, takes away the heat on the surface of the film, and cools the film efficiently.

[0068] S2, conveying: when the one-way liquid inlet valve 37 and the one-way liquid outlet valve 36 move close to the partition 34, the threaded protrusion 311 squeezes the spring telescopic rod 312, so that the spring telescopic rod 312 rotates forward around the threaded protrusion 311, and the spring telescopic rod 312 drives the driving tube 32 and the elliptical tube 31 to rotate forward, and the elliptical tube 31 rotates to convey the film, which is convenient for the stable movement of the film. When the one-way liquid inlet valve 37 and the one-way liquid outlet valve 36 move away from the partition 34, the threaded protrusion 311 squeezes the inclined surface 313, so that the spring telescopic rod 312 shrinks away from the threaded protrusion 311, and the spring telescopic rod 312 is prevented from rotating in the opposite direction;

[0069] S3, dust collection: during the rotation of the elliptical tube 31, the tension tube 315 is squeezed to move downward, and the tension tube 315 drives the short tube 316 and the liquid collecting box 332 to move downward. The liquid collecting box 332 compresses the telescopic tube 318, and the pressure in the inner cavity of the telescopic tube 318 increases, so that the gas in the inner cavity of the telescopic tube 318 is discharged through the second one-way air outlet valve 333. When the tension tube 315 returns to its original position, it drives the liquid collecting box 332 to return to its original position and stretches the telescopic tube 318, so that the second one-way air inlet valve 325 is opened, and the second one-way air inlet valve 325 is connected to the connecting pipe 329. The gas in the inner cavity of the dust box 328 is absorbed, and negative pressure is generated in the inner cavity of the dust box 328. The dust on the surface of the film is collected in the inner cavity of the dust box 328 through the dust suction pipe 326 and the three-way pipe 327 in turn, and the film is dusted. When the piston plate 35 is close to the partition plate 34, negative pressure is generated in the inner cavity of the connecting shell 314 on the right side, so that the first one-way air intake valve 323 is opened. The first one-way air intake valve 323 absorbs the gas in the inner cavity of the dust box 328 through the hose and the connecting pipe 329, thereby enhancing the suction strength of the dust box 328 and enhancing the dust suction effect.

[0070] S4, cutting: The right side of the film is wound on the film storage device. During the storage process, the front and rear sides of the film are cut by the cutting knife 24 to cut a film of a certain width. When adjusting the distance between the front and rear cutting knives 24, the electric push rod 29 is controlled to contract to drive the first inclined plate 21 to move, and the first inclined plate 21 drives the support rod 27 to move. The support rod 27 drives the protective shell 20 to move through the sliding sleeve 26, so that the two protective shells 20 contact each other, so that the semicircular groove 213 is engaged with the driving rod 214, and the rotating turntable 218 drives the fixed block 217, the threaded rod 216, the moving block 215 and the driving rod 214 to rotate. The inner wall is threadedly connected, so that the front and rear protective shells 20 are close to or away from each other, thereby driving the cutting knife 24 to move, and adjusting the distance between the front and rear cutting knives 24. After the adjustment is completed, the two protective shells 20 are separated, and the cutting knife 24 returns to its original position. The rotating threaded rod 216 thread drives the moving block 215 to move, and the moving block 215 drives the driving rod 214 to move, so that the two driving rods 214 are separated, and the driving rod 214 is clamped with the semicircular groove 213. The external thread on the surface of the driving rod 214 is clamped with the internal thread on the inner wall of the semicircular groove 213, so that the protective shell 20 is positioned and supported, and then the cutting knife 24 is positioned and supported, thereby enhancing the stability of the cutting knife 24.

[0071] S5. Replace the cutting knife 24: Rotate the fastening bolt 25 and threadably connect it with the mounting sleeve 23 to separate the fastening bolt 25 from the cutting knife 24, and disassemble and replace the cutting knife 24. When not in use, close the two protective shells 20 through operation to store the cutting knife 24 in the inner cavity of the protective shell 20, hide and protect the cutting knife 24, and prevent external personnel and objects from accidentally touching the cutting knife 24.
