[0025] Please see Figure 1-4 This utility model provides a technical solution: a blown film machine with a heat preservation structure, such as... Figure 1 and Figure 2 As shown, it includes a support structure 1, which includes a base box 11. A buffer support assembly 12 is fixed to the lower side of the base box 11. The buffer support assembly 12 includes a first support plate 121. A spring shaft 122 is fixed to the lower side of the first support plate 121. An anti-slip base plate 123 is fixed to the lower side of the spring shaft 122.
[0026] Among them, the control device for controlling the overall equipment is fixed on the base box 11. The telescopic structure in this application is a hydraulic cylinder, which is the prior art.
[0027] Furthermore, a support frame is fixed to the upper left side of the bottom box 11, and an air inlet hood is fixed on the support frame. The air inlet hood is connected to the exhaust gas processor through an air supply pipe. With the assistance of the exhaust gas processor, the harmful gases generated during the blown film processing are treated, thereby improving the quality of the operating environment.
[0028] Specifically, there are two sets of buffer support components 12, and the two sets of buffer support components 12 are symmetrically arranged about the central axis of the bottom box 11;
[0029] In the above scheme, the anti-slip base plate 123 plays an anti-slip role, and the spring shaft 122 on the first support plate 121 plays a buffering role.
[0030] like Figure 1 and Figure 2 As shown, a blown film structure 2 is fixed on the support structure 1. The blown film structure 2 includes a first motor housing 21. A motor in the first motor housing 21 drives a first rotating rod 22 to rotate. The first rotating rod 22 is rotatably connected to a rotating screw 25. The rotating screw 25 is located inside the first guide pipe 23 and the hot melt insulation component 24. The hot melt insulation component 24 is connected to the first guide pipe 23 and the first discharge pipe 26. The first discharge pipe 26 is connected to the blown film die head 27. The hot melt insulation component 24 includes a second guide pipe 241. An electric heater 242 is fixed on the second guide pipe 241. An insulation layer 243 is fixed on the outer wall of the electric heater 242. An anti-scalding layer 244 is fixed on the insulation layer 243.
[0031] Among them, the electric heater 242 is a serpentine wound electric heating wire, which ensures uniform heating treatment in the second feed tube 241. A temperature sensor is fixed on the second feed tube 241, and the temperature sensor model is CWDZ11.
[0032] In the above scheme, the first rotating rod 22 is driven to rotate by the motor in the first motor box 21. The rotation of the first rotating rod 22 drives the rotating screw 25 to rotate, thereby uniformly feeding the plastic particles in the first guide tube 23 and the second guide tube 241. The plastic particles are heat-melted by the electric heater 242. The high temperature after heating by the electric heater 242 plays an auxiliary heat preservation role with the assistance of the heat insulation layer 243 and the anti-scalding role with the assistance of the anti-scalding layer 244. The adhesive enters the blown film die head 27 through the first discharge pipe 26 and is blown film processed and shaped with the assistance of the blown film die head 27.
[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the upper side of the blown film structure 2 is connected to the feeding and storage structure 3. The feeding and storage structure 3 includes a raw material box 31, with a feeding pipe 32 passing through the upper side of the raw material box 31. A scraping assembly 33 is fixed on the raw material box 31, and an auxiliary discharge assembly 34 is slidably connected to the scraping assembly 33. The lower side of the raw material box 31 is connected to the discharge adjustment assembly 35. The scraping assembly 33 includes a second motor box 331. The motor in the second motor box 331 drives the second rotating rod 332 to rotate. The rotation of the second rotating rod 332 passes through the connecting rod 333 and drives the scraper.

[0034] The raw material box 31 is arranged in a ring shape, and two sets of scraper blades 334 are provided, with the two sets of scraper blades 334 arranged symmetrically about the central axis of the raw material box 31.
[0035] Specifically, there are four sets of sliding rods 342, and the four sets of sliding rods 342 are symmetrically arranged about the central axis of the second rotating rod 332;
[0036] In the above scheme, plastic particles are stored inside the raw material box 31 through the feed pipe 32. Inside the second motor box 331, the motor drives the second rotating rod 332 to rotate. The rotation of the second rotating rod 332 drives the scraper 334 on the connecting rod 333 to rotate. With the assistance of the hydraulic cylinder on the fixed plate 341, the hydraulic rod drives the sliding rod 342 to move in the first slide groove 343, thereby driving the rotating rod 344 to move downward, thus avoiding blockage of the second discharge pipe 355. With the assistance of the hydraulic cylinder on the connecting plate 351 inside the storage box 352, the adjusting plate 353 moves in the second slide groove 354, thereby adjusting the discharge port of the second discharge pipe 355.
[0037] Working principle: When using the blown film machine with heat preservation structure, the external power supply is turned on, and the blown film structure 2 is supported by the support structure 1. The blown film is processed with the assistance of the blown film structure 2, and the plastic particles are stored with the assistance of the feeding and storage structure 3.
