Description

Technical Field

[0001] This utility model belongs to the field of blown film machine technology, and specifically relates to a blown film mechanism for a blown film machine. Background Technology

[0002] A blown film machine is a mechanical device that heats and melts plastic granules and blows them into a thin film. It is widely used in the plastics processing industry. The blown film mechanism is the core part of the blown film machine. Its main function is to heat, melt, and plasticize plastic raw materials and then extrude them to form a film.

[0003] During the blown film process, the plastic film rubs against various parts of the equipment (such as the extruder screw, die head, traction roller, etc.), and the intermolecular interactions during high-speed movement and stretching of the film lead to the separation and accumulation of charges, thereby generating static electricity. Existing blown film mechanisms cannot remove static electricity, which easily causes dust adsorption and affects film quality. Therefore, a technical measure is proposed to solve the problem that existing blown film mechanisms cannot remove static electricity, easily cause dust adsorption, and require improvement in film quality. Utility Model Content

The antistatic component is mounted on the upper surface of the housing. Thanks to the antistatic component, static electricity on the surface of the blown film is easily removed, preventing dust in the air from adsorbing onto the film, ensuring the quality of the film. Furthermore, the ionized air blown out by the antistatic component itself is filtered, improving cleanliness.

[0008] Furthermore, the lower part of the box is equipped with multiple sets of evenly distributed casters.

[0011] Furthermore, the air duct is L-shaped, and a first box is connected to the lower end of the air duct. The first box is installed inside the lower part of the housing. A first filter screen is movably installed in the first box. A blower is installed at the other end of the first box. The blower is installed inside the lower part of the housing.

[0012] Furthermore, the static elimination component includes an ion fan, which is installed on the upper surface of the housing at the middle position of one end near the vertical plate.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention facilitates air filtration by using a first housing and a first filter, preventing dust from adhering to the membrane surface and improving the cleanliness of the membrane. The blower blows air into the housing, where it is filtered by the first filter.

[0017] The antistatic component facilitates the removal of static electricity from the blown film surface, preventing dust in the air from adhering to the film and ensuring its quality.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This specific embodiment is a blown film mechanism for a blown film machine, and its structural schematic diagram is shown below. Figure 1 , Figure 2 , Figure 3As shown, the device includes a housing 1, a vertical plate 6 mounted on the upper surface of the housing 1, a machine head 11 mounted on the upper surface of the housing 1, a die head 13 mounted on the upper part of the machine head 11, an air ring 14 sleeved on the upper end of the die head 13, multiple sets of evenly distributed round holes 15 opened on the upper end of the air ring 14, an air guide pipe 12 connected through the lower part of the air ring 14, an interface pipe 16 connected through the side of the air guide pipe 12, an anti-static component 2 connected to the interface pipe 16, the anti-static component 2 mounted on the upper surface of the housing 1, multiple sets of evenly distributed casters 5 mounted on the lower part of the housing 1, an extrusion injection mechanism 3 mounted on the upper surface of the housing 1, a material cylinder 4 mounted through the upper end of the extrusion injection mechanism 3, an extrusion mechanism 9 mounted on the side of the upper end of the vertical plate 6 near the material cylinder 4, a guide roller 8 mounted on the side of the upper end of the vertical plate 6 away from the extrusion mechanism 9, a winding mechanism 7 mounted on the side of the vertical plate 6 near the guide roller 8, a baffle 10 mounted on the lower side of the vertical plate 6, and an air guide pipe 1... 2 is L-shaped, with the lower end of the air duct 12 connected to the first box 17. The first box 17 is installed inside the lower part of the box 1. The first filter 18 is movably installed in the first box 17. The other end of the first box 17 is equipped with a blower 19, which is installed inside the lower part of the box 1. In actual operation, plastic granules are put into the material cylinder 4 and hot-melt injection is performed by the extrusion pushing mechanism. Then the hot-melt plastic enters the die head 11 and the die head 13, and is then extruded into a film. The film then passes through the extrusion mechanism 9, the guide roller 8, and the winding mechanism 7. When the operation starts, the blower 19 is started, and the blower 19 blows air into the first box 17. The air is filtered by the first filter 18 and then enters the air duct 12. The air then enters the air ring 14 and the round hole 15 through the air duct 12 to cool the film. When the blower 19 is started, the anti-static component 2 is started simultaneously to remove static electricity from the surface of the film.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the antistatic component 2 includes an ion fan 202, which is installed on the upper surface of the housing 1 near the middle of one end of the vertical plate 6. The ion fan 202 is connected to a connecting part 203, which passes through the lower end of the vertical plate 6. The other end of the connecting part 203 is connected to a second housing 201. A second filter 204 is movably installed in the second housing 201. A vertical pipe 205 is installed through the middle of the upper part of the second housing 201, and a telescopic pipe 206 is connected to the vertical pipe 205. The other end of the telescopic pipe 206 is connected to an interface pipe 16. When the ion fan 202 is activated (the principle of the ion fan 202 is that when an object surface carrying static electricity approaches the ion stream blown out by the ion fan 202, if the object surface carries positive static electricity, negative ions will be attracted to the object surface and neutralize the positive charge, reducing the number of positive charges on the object surface; if the object surface carries negative static electricity, negative ions will be attracted to the object surface and neutralize the positive charge, reducing the number of positive charges on the object surface); if the object surface carries negative ... negative charges on the object surface, reducing the number of negative charges on the object surface, reducing the number of negative charges on the object surface, reducing the number of negative charges on the object surface, reducing the number of negative charges on the object surface, reducing the number of negative charges on the object surface, reducing the number of negative charges on the object surface, reducing the number of negative charges on the object surface, reducing the number of negative charges on the object surface, When there is negative static electricity, positive ions are attracted to the surface of the object and neutralize the negative charge, thereby reducing the number of negative charges on the surface. Through this neutralization effect of positive and negative ions with the static charge on the surface of the object, the static electricity on the surface of the object is eventually eliminated, reaching a near-neutral state. The ions blown out by the ion fan 202 pass through the connecting part 203, and then enter the second box 201 and the second filter 204 (the second filter 204 is a stainless steel metal filter, which has little impact on the ion adsorption of the ion fan 202 and is widely used in ion fans 202 in the chemical and machinery industries). Then, the ions blown out by the ion fan 202 enter the vertical pipe 205 and the telescopic pipe 206. Then, the ions blown out by the ion fan 202 enter the interface pipe 16, the air guide pipe 12, the air ring 14, and the round hole 15. Finally, the ions blown out by the ion fan 202 remove static electricity from the membrane.

[0027] Working principle: In actual operation, plastic granules are placed into the material cylinder 4 and hot-melt injection is performed by the extrusion pushing mechanism. The hot-melt plastic then enters the die head 11 and the die head 13, and is then extruded into a film. The film then passes through the extrusion mechanism 9, the guide roller 8, and the winding mechanism 7. When the operation starts, the blower 19 is started, which blows air into the first box 17. The air is filtered by the first filter screen 18 and then enters the air guide pipe 12. The air then enters the air ring 14 and the round hole 15 through the air guide pipe 12 to cool the film. When the blower 19 is started, the anti-static component 2 is started simultaneously to remove static electricity from the film surface. The first box 17 and the first filter screen 18 facilitate air filtration, prevent dust in the air from adhering to the film surface, and improve the cleanliness of the film.

[0028] The specific working principle of the static electricity elimination component 2 is as follows: Ion fan 202 is activated (the principle of ion fan 202 is that when a surface of an object with static electricity approaches the ion stream blown out by ion fan 202, if the surface of the object has positive static electricity, then negative ions will be attracted to the surface of the object and neutralize the positive charge, thus reducing the number of positive charges on the surface of the object; if the surface of the object has negative static electricity, then positive ions will be attracted to the surface of the object and neutralize the negative charge, thus reducing the number of negative charges on the surface of the object. Through this neutralization effect of positive and negative ions with the static charge on the surface of the object, the static electricity on the surface of the object is finally eliminated, reaching a state close to electrical neutrality). The ions blown out by ion fan 202 pass through connection part 203, and then the ions enter the second box. 201. The second filter 204 (the second filter 204 is a stainless steel metal filter, which has little impact on the ion adsorption of the ion blower 202 and is widely used in ion blowers 202 in the chemical and machinery industries) then blows ions upward into the vertical pipe 205 and the telescopic pipe 206. Subsequently, the ions blown out by the ion blower 202 enter the interface pipe 16, the air guide pipe 12, the air ring 14, and the round hole 15. The ions blown out by the ion blower 202 then remove static electricity from the membrane. The setting of the static removal component 2 facilitates the removal of static electricity from the surface of the blown membrane, preventing dust in the air from adsorbing onto the membrane, ensuring the quality of the membrane. In addition, the ion air blown out by the static removal component 2 itself is filtered, improving the cleanliness.
