Description

Technical Field

[0001] This utility model relates to the field of paper cup production technology, specifically to a device for removing static electricity from cup film packaging. Background Technology

[0002] Paper cups are paper containers made by mechanically processing and bonding paper made from chemical wood pulp. They are shaped like cups. Paper cups are convenient to carry, easy to use, and inexpensive, making them common liquid containers in many homes and public places. Paper cups are categorized by use, such as cold drink cups, hot drink cups, and yogurt cups. Paper cup lamination mainly involves applying a transparent plastic film to the surface through heat pressing to protect the design and increase its gloss. During the coating process of paper cup raw materials, the paper cups rub against various parts during the conveying process, which makes them extremely prone to static electricity. Static electricity can cause the paper cup raw materials to be coated incompletely, affecting the overall coating quality and thus reducing the overall production quality of the cups. Most existing static electricity removal methods use static eliminator bars in conjunction with fans to eliminate static electricity. However, existing traditional static eliminators are mostly fixed in design, and the distance between them and the paper cup raw material cannot be adjusted. As a result, they cannot meet the static elimination needs of paper cup raw materials of different thicknesses in actual use, and have certain limitations. To address this, this utility model proposes a cup film packaging static eliminator that can dynamically adjust the static elimination distance to solve the above-mentioned technical problems. Utility Model Content

[0009] Preferably, mounting holes are provided on the outer walls of the mounting legs at both ends.

[0010] Preferably, the positive terminal and the negative terminal are electrically connected to the power terminals of the static eliminator rod.

It can effectively remove static electricity from the raw materials before coating, and has a good static electricity removal effect, reducing the impact of static electricity on the coating of cups. This can effectively improve the coating quality of cups, thereby increasing the yield of cup production and avoiding the reduction of production quality. Moreover, the static electricity removal device of this utility model has a simple overall structure, is compact and practical, occupies little space, is easy to manufacture, and has low maintenance costs, making it suitable for supporting implementation. Meanwhile, this utility model allows the antistatic shell at the top to move back and forth by extending or retracting the threaded adjustment column.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figure 1-4This utility model provides an embodiment of an antistatic device for cup film packaging, including a mounting bracket 1. A threaded hole is provided at the center of the mounting bracket 1, and a threaded adjusting column 2 is threadedly connected to the threaded hole. The top of the threaded adjusting column 2 is connected to an antistatic shell 4 via a bearing. This structural design allows for manual rotation of the threaded adjusting column 2. When the threaded adjusting column 2 rotates clockwise or counterclockwise, it can extend or retract within the threaded hole. This extension or retraction of the threaded adjusting column 2 drives the antistatic shell 4 at the top to move back and forth. This movement of the antistatic shell 4 adjusts the distance between it and the paper cup material, providing a dynamic adjustment effect for the antistatic distance. The distance between the antistatic shell 4 and the paper cup material can be dynamically adjusted according to different installation and usage requirements, exhibiting good structural applicability, improving structural flexibility, effectively reducing usage limitations, and enhancing overall applicability. Furthermore, an antistatic rod 9 is fixedly installed inside the antistatic housing 4. The antistatic rod 9 is a mature existing technology product, which can be obtained directly by purchasing from the market without any creative effort. Small fans 10 are fixedly installed on the upper and lower outer surfaces of the antistatic housing 4 by bolts. A positive terminal connector 11 is fixedly installed on the outer wall of one end of the antistatic housing 4, and a negative terminal connector 12 is fixedly installed on the outer wall of the other end of the antistatic housing 4. The positive terminal connector 11 and the negative terminal connector 12 are electrically connected to the power receiving end of the antistatic rod 9, so that the power receiving operation can be performed through the positive terminal connector 11 and the negative terminal connector 12. This structural design allows for the removal of static electricity from the raw material cardboard used in paper cup production. The static elimination rod 9 is designed to work by eliminating static electricity. The working principle of the static elimination rod 9 is mainly based on high-voltage tip discharge and air ionization to neutralize charges. Its core components include a high-voltage power generator and a discharge electrode, which is usually an ion needle. The high-voltage corona discharge at the tip ionizes the air into a large number of positive and negative ions. Then, the small fan 10 can be set up to work. The small fan 10 blows the ion airflow generated by the static elimination rod 9 onto the outer surface of the paper cup raw material. The static electricity on the surface of the paper cup raw material and the positive and negative ions in the airflow undergo charge transfer, eventually reaching charge balance and eliminating static electricity, thereby achieving the static removal treatment of the cup coating.

[0018] In this embodiment, in order to provide a certain limiting and guiding effect for the back-and-forth movement of the antistatic housing 4, limiting guide posts 5 are fixedly installed on both sides of the outer wall of the back of the antistatic housing 4. The top of the limiting guide post 5 is set through the mounting bracket 1, and the limiting guide post 5 is slidably connected to the mounting bracket 1. The limiting guide post 5 can provide a certain displacement guidance when the antistatic housing 4 moves back and forth, which has a good limiting and guiding effect, improves the linearity of movement, and ensures the use effect.

[0019] In this embodiment, in order to prevent the end of the limiting guide post 5 from detaching, an anti-detachment component 6 is fixedly installed on the top of each of the two limiting guide posts 5. The diameter of the anti-detachment component 6 is larger than the diameter of the limiting guide post 5. Thus, the top of the limiting guide post 5 can be prevented from detaching from the mounting bracket 1 by the anti-detachment component 6.

[0020] In this embodiment, in order to facilitate the manual rotation of the threaded adjusting column 2, a nut 3 is fixedly installed on the top of the threaded adjusting column 2. The nut 3 is provided with anti-slip serrations on the outside, so that the threaded adjusting column 2 can be driven to rotate manually through the nut 3.

[0021] In this embodiment, in order to facilitate the installation of the static electricity removal device of this utility model, mounting feet 7 are fixedly installed on the outer walls of both ends of the mounting bracket 1. The mounting feet 7 and the mounting bracket 1 are integrally formed. Mounting holes 8 are opened on the outer walls of the mounting feet 7 at both ends. With this structural design, the present invention can be installed on the feed end of a suitable laminating machine through the mounting feet 7 and mounting holes 8. In this way, the static electricity removal device of the present invention can be used to remove static electricity from the paper cup raw materials before laminating.

[0022] Working principle: The static elimination device of this utility model has mounting feet 7 at both ends of the mounting bracket 1. The mounting feet 7 can be used to install this utility model on the feed end of a suitable laminating machine, thereby ensuring the normal use of this utility model. When static electricity needs to be eliminated, the static eliminator 9 can be used. The working principle of the static eliminator 9 is mainly based on high-voltage tip discharge and air ionization to neutralize charges. Its core components include a high-voltage power generator and a discharge electrode (usually an ion needle). The air is ionized into a large number of positive and negative ions through high-voltage corona discharge at the tip. Then, the small fan 10 can work. The small fan 10 blows the ion airflow generated by the static elimination rod 9 onto the outer surface of the paper cup raw material. The static electricity on the surface of the paper cup raw material and the positive and negative ions in the airflow undergo charge transfer, eventually reaching charge balance and eliminating static electricity, thereby achieving the static removal treatment before the cup is coated. The static electricity removal device of this utility model can conveniently complete the static electricity removal work of the coating of raw materials for cup production. It can effectively remove static electricity from the raw materials before coating, and has a good static electricity removal effect, reducing the impact of static electricity on the coating of cups. This can effectively improve the coating quality of cups, thereby increasing the yield of cup production and avoiding the reduction of production quality. Moreover, the static electricity removal device of this utility model has a simple overall structure, is compact and practical, occupies little space, is easy to manufacture, and has low maintenance costs, making it suitable for supporting implementation. Meanwhile, the nut 3 of this invention allows the threaded adjusting column 2 to be manually rotated. When the threaded adjusting column 2 rotates clockwise or counterclockwise, it can extend or retract within the threaded hole. The extension or retraction of the threaded adjusting column 2 can move the antistatic shell 4 at the top back and forth. This movement of the antistatic shell 4 can adjust the distance between it and the paper cup raw material, providing a dynamic adjustment effect for the antistatic distance. The distance between the shell and the paper cup raw material can be dynamically adjusted according to different installation and usage requirements, meeting the actual needs of antistatic treatment for paper cup raw materials of different thicknesses, thus achieving better antistatic effects. It has good structural applicability, improves the flexibility of use, effectively reduces usage limitations, and has stronger applicability.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
