Description

Technical Field

[0001] This utility model is a winding and static elimination device, belonging to the field of film processing. Background Technology

[0002] During the winding process of materials such as films, static electricity is easily generated due to friction and peeling between the material and equipment. The accumulation of static electricity not only causes dust to adhere to the material and affect winding quality, but it can also trigger discharge phenomena, posing safety hazards. Currently, most common static eliminators use ion blowers. Their working principle involves generating positive and negative ions through high-voltage electrodes, and then using airflow to blow the ions onto the surface of the wound material to neutralize static electricity. However, when the airflow generated by the ion blower blows onto the film surface, the airflow is obstructed by the film and flows away from it. This results in a short contact time between the airflow and the film, meaning that the positive and negative ions in the airflow generated by the ion blower cannot fully neutralize the static electricity on the film surface, leading to low ion utilization. This situation not only affects the static eliminator effect but also wastes ion resources to some extent. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a winding static electricity removal device to solve the problems mentioned in the background technology. This utility model increases the contact time between the wind generated by the ion fan and the film, thereby improving the utilization rate of ion resources.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a winding and static elimination device includes a guide roller, with equipment boxes rotatably mounted at both ends of the guide roller. A reversing roller for changing the film conveying direction is provided obliquely above the guide roller. The two ends of the reversing roller are rotatably connected to two equipment boxes respectively. An inclined hollow box is provided between the reversing roller and the guide roller. An elongated oval opening is provided on two parallel sides of the hollow box. The film passes through the channel formed by the two elongated oval openings. The hollow box is connected to the two equipment boxes through a connector. A U-shaped tube is fitted at one end of the hollow box. Air distribution pipes are installed at both ends of the U-shaped tube. Multiple branch pipes connected and communicating with the hollow box are installed on the outer surface of the air distribution pipes. A pipe joint for connecting the air outlet of an ion blower is installed on the outer surface of the U-shaped tube. Arc-shaped covers are installed at both ends of the elongated oval opening of the hollow box. The two arc-shaped covers are arranged concentrically with the guide roller and the reversing roller respectively. A guide plate is installed at the end of the arc-shaped cover away from the hollow box.

[0005] Furthermore, the connector includes a connecting plate, which is installed on the side of the hollow box facing the equipment housing. The connecting plate has an L-shaped structure, and the end of the connecting plate away from the hollow box is attached to the equipment housing. The part of the connecting plate that is attached to the equipment housing is connected to the equipment housing by multiple screws.

[0006] Furthermore, a limiting plate for limiting the position of the screw head is installed on the horizontal part of the connecting plate. The limiting plate is parallel to the vertical part of the connecting plate, and there is a gap between the limiting plate and the vertical part of the connecting plate. A plurality of first small holes are opened on one side of the limiting plate, and a plurality of second small holes that cooperate with the first small holes are opened on the vertical part of the connecting plate. One end of the screw passes through the first small hole and the second small hole in sequence and is threadedly connected to the equipment box.

[0007] Furthermore, a plurality of parallel bottom beams are provided between the two equipment boxes, and the two ends of the bottom beams are respectively connected to the two equipment boxes by bolts.

[0008] Furthermore, the air guide plate and the arc-shaped cover are integrally formed, and the air guide plate and the part of the film at the air guide plate are parallel.

[0009] Furthermore, a connecting ring is installed at the end of the pipe fitting away from the U-shaped pipe, and multiple circular holes are equidistantly spaced on one side of the connecting ring.

[0010] The beneficial effects of this utility model are:

[0011] The membrane passes through the elongated oval opening of the hollow box. The arc-shaped covers at both ends are concentrically arranged with the guide rollers and reversing rollers. Together with the air guide plate, the airflow is confined to the surface of the membrane, forming a surrounding airflow channel. The air guide plate at the end of the arc-shaped cover is arranged parallel to the membrane, guiding the blown ion wind along the surface of the membrane and reducing airflow rebound loss. The concentric design of the arc-shaped cover with the guide rollers and reversing rollers ensures that the airflow flows closely to the surface of the membrane in the bending section. Especially when the membrane is reversing, it can still maintain effective contact between the ion wind and the membrane, avoiding airflow interruption caused by membrane bending, thus prolonging the contact time between the ion wind and the membrane and improving the ion neutralization efficiency.

Detailed Implementation

[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] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a winding and static elimination device, including a guide roller 1, with equipment boxes 3 rotatably mounted at both ends of the guide roller 1. A reversing roller 14 for changing the conveying direction of the film 2 is provided diagonally above the guide roller 1. The two ends of the reversing roller 14 are rotatably connected to the two equipment boxes 3 respectively. The reversing roller 14 and the guide roller 1 together play the role of limiting the conveying path of the film 2. A plurality of parallel bottom beams 4 are provided between the two equipment boxes 3, and the two ends of the bottom beams 4 are connected to the two equipment boxes 3 respectively by bolts, thereby improving the stability of the overall structure.

[0021] See Figures 1-5 A hollow box 8 is arranged at an angle between the reversing roller 14 and the guide roller 1. Each of the two parallel sides of the hollow box 8 has an elongated oval opening 16 through which the film 2 passes. A connecting plate 13 is installed on the side of the hollow box 8 facing the equipment housing 3. The connecting plate 13 has an L-shaped structure, with the end of the connecting plate 13 away from the hollow box 8 fitting against the equipment housing 3. The part of the connecting plate 13 that fits against the equipment housing 3 is connected to the equipment housing 3 by multiple screws 11. A limiting plate 12 is installed on the horizontal part of the connecting plate 13 to limit the position of the screw heads. The limiting plate 12 is aligned with the vertical part of the connecting plate 13. The limiting plate 12 and the vertical part of the connecting plate 13 are parallel and have a gap. The limiting plate 12 has a number of first small holes on one side and the connecting plate 13 has a number of second small holes that cooperate with the first small holes on the vertical part. The screw 11 passes through the first small hole and the second small hole in sequence and is threaded to the equipment box 3, thus limiting the relative position of the hollow box 8 and the equipment box 3. Under the limitation of the limiting plate 12, the head of the screw 11 does not contact the vertical part of the connecting plate 13. When the screw 11 cannot be removed smoothly with tools such as wrenches, the screw 11 can be cut off by using the gap between the limiting plate 12 and the connecting plate 13.

[0022] See Figures 1-5 A U-shaped tube 5 is fitted onto one end of a hollow box 8. Air distribution pipes 10 are installed at both ends of the U-shaped tube 5. Multiple branch pipes 9 connected to and communicating with the hollow box 8 are installed on the outer surface of the air distribution pipes 10. A pipe connector 6 for connecting to the outlet end of the ion fan is installed on the outer surface of the U-shaped tube 5. A connecting ring is installed at the end of the pipe connector 6 away from the U-shaped tube 5. Multiple circular holes are equidistantly spaced on one side of the connecting ring. Arc-shaped covers 7 are installed at both ends of the oblong opening 16 of the hollow box 8. The two arc-shaped covers 7 are concentrically arranged with the guide roller 1 and the reversing roller 14, respectively. A guide plate 15 is installed at the end of the arc-shaped cover 7 away from the hollow box 8. The guide plate 15 and the arc-shaped cover 7 are integrally formed. The guide plate 15 and the film 2 are located at the guide plate 15. The parts are parallel, and the membrane 2 passes through the elongated oval opening 16 of the hollow box 8. The arc-shaped covers 7 at both ends of the hollow box 8 are arranged concentrically with the guide roller 1 and the reversing roller 14. Together with the air guide plate 15, the airflow is restricted to the surface of the membrane 2, forming a surrounding airflow channel. The air guide plate 15 at the end of the arc-shaped cover 7 is arranged parallel to the membrane 2, guiding the blown ion wind along the surface of the membrane 2 and reducing airflow rebound loss. The concentric design of the arc-shaped cover 7 with the guide roller 1 and the reversing roller 14 ensures that the airflow flows closely to the surface of the membrane 2 in the curved section. Especially when the membrane 2 is reversing, it can still maintain effective contact between the ion wind and the membrane 2, avoiding airflow interruption caused by the bending of the membrane 2, thus prolonging the contact time between the ion wind and the membrane 2 and improving the ion neutralization efficiency.
