Technical Field

[0001] This utility model relates to the field of film blow molding machine technology, and specifically to a film blow molding machine. Background Technology

[0002] A film blow molding machine is a device used to heat and melt plastic particles and then blow them into a film. This device heats and melts plastic particles and then uses blow molding technology to blow the molten plastic into a film. It is widely used in packaging, construction and other fields. However, existing film blow molding machines have certain inconveniences when used.

[0003] First, existing film blow molding machines emit an odor from the blown film surface, which can easily affect health and pollute the environment. Second, existing film blow molding machines are prone to material accumulation and blockage at the inlet of the feed pipe, which affects the feeding effect.

[0004] Therefore, we propose a film blow molding machine. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The purification ring, which surrounds the outside of the blown film, allows for air extraction via a fan. Odors from the film surface are drawn in through the perforated panel and then filtered through the filter tube, where they are purified by the filter cotton. This reduces odors on the film surface and minimizes harm to humans. The anti-clogging device features an internal vibrating frame positioned above the injection tube. When material accumulates in the injection tube, the vibration motor is activated, causing the frame to vibrate. This vibration, via a connecting spring, causes the frame to sway left and right. During this swaying, a striking rod strikes the injection tube, allowing accumulated material to pass through quickly. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a film blow molding machine includes a head 1, with a film inlet 2 on the upper outer surface of the head 1. A purification ring 3 is located above the head 1, and a first fixed support rod 4 is provided between the purification ring 3 and the head 1. A cooling ring 5 is located above the purification ring 3, and a second fixed support rod 6 is provided between the cooling ring 5 and the purification ring 3. Both the inner walls of the cooling ring 5 and the purification ring 3 are provided with perforated panels 7. A blower 8 is located on the outer wall of the cooling ring 5. An air guide pipe 9 and an injection pipe 10 are located on the outer wall of the head 1. The air guide pipe 9 is located on one side of the injection pipe 10. A heating device 11 and an anti-blocking device 12 are located on the outer wall of the injection pipe 10. The heating device 11 is located on the outer wall of the anti-blocking device 12. On one side, the outer wall of the purification ring 3 is provided with a filter tube 13, the top outer surface of the filter tube 13 is provided with a top cover 14, the top outer surface of the top cover 14 is provided with an exhaust fan 15, the inner wall of the filter tube 13 is provided with a magnetic suction plate 16, the upper outer surface of the magnetic suction plate 16 is provided with a metal filter plate 17, the middle part of the metal filter plate 17 is provided with a purification filter cotton 18, a fixing plate 19 is provided between the anti-clogging device 12 and the injection pipe 10, a vibration frame 20 is provided in the middle of the anti-clogging device 12, a connecting spring 21 is provided between the vibration frame 20 and the anti-clogging device 12, and a striking rod 22 and a vibration motor 23 are provided on the inner wall of the vibration frame 20, with the striking rod 22 located on both sides of the vibration motor 23.

[0021] Furthermore, the outer wall of the purification ring 3 is fixedly connected to the bottom outer surface of the filter tube 13, the top outer surface of the filter tube 13 is detachably connected to the bottom outer surface of the top cover 14, and the top outer surface of the top cover 14 is detachably connected to the bottom outer surface of the exhaust fan 15. When in use, the purification ring 3 surrounds the outside of the blown membrane and can draw in air through the exhaust fan 15. The odor on the surface of the membrane can be drawn in through the perforated panel 7 and then enter the filter tube 13. It is then purified and filtered through the purification filter cotton 18 inside the filter tube 13, thereby reducing the odor on the surface of the membrane and reducing the harm to the human body.

[0022] Furthermore, the inner wall of the filter tube 13 is fixedly connected to the magnetic absorbing sheet 16. There are two sets of magnetic absorbing sheets 16. The upper outer surface of the magnetic absorbing sheet 16 is detachably connected to the lower outer surface of the metal filter plate 17. When in use, the magnetic absorbing sheet 16 can magnetically attract the metal filter plate 17, which makes it easy to disassemble and assemble the metal filter plate 17.

[0023] Furthermore, the anti-blocking device 12 is fixedly connected to the injection pipe 10 via the fixing plate 19, and the vibrating frame 20 is movably connected to the anti-blocking device 12 via the connecting spring 21. When in use, the vibrating frame 20 inside the anti-blocking device 12 is positioned above the injection pipe 10. When material accumulates inside the injection pipe 10, the vibration motor 23 can be activated, causing the vibration motor 23 to vibrate the vibrating frame 20, which in turn causes the vibrating frame 20 to sway left and right via the connecting spring 21. During the swaying process, the striking rod 22 can strike the injection pipe 10, allowing the material accumulated inside the injection pipe 10 to pass through quickly.

[0024] Furthermore, the inner wall of the vibrating frame 20 is fixedly connected to the outer surface of one end of the striking rod 22. There are two sets of striking rods 22, and one end of the striking rod 22 is provided with a hammer. The hammer is mainly used to strike the injection pipe 10 during use.

[0025] Furthermore, the purification ring 3 is fixedly connected to the machine head 1 via the first fixed support rod 4, and the cooling ring 5 is fixedly connected to the purification ring 3 via the second fixed support rod 6. The cooling ring 5 can cool and reduce the temperature of the blown film during use.

[0026] Working Principle: This invention relates to a film blow molding machine. During operation, material is fed into the machine head 1 through the injection pipe 10. Air is then blown into the machine head 1 through the air guide pipe 9. The material is then blown out through the film outlet 2. During blowing, a purification ring 3 surrounds the outside of the blown film. The exhaust fan 15 draws in air, drawing in odors from the film surface through the perforated panel 7. These odors then enter the filter pipe 13 and are purified by the purification filter cotton 18 within the filter pipe 13, thereby reducing odors on the film surface. Odor reduction can decrease harm to the human body. The subsequent cooling ring 5 can cool the film through the blower 8. When the anti-blocking device 12 is in use, the internal vibration frame 20 is located above the injection tube 10. When the material in the injection tube 10 accumulates, the vibration motor 23 can be started, which can make the vibration motor 23 vibrate the vibration frame 20, causing the vibration frame 20 to swing left and right through the connecting spring 21. During the swinging process, the striking rod 22 can strike the injection tube 10, which can make the material accumulated inside the injection tube 10 pass through quickly, which is quite practical.
