Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to an antistatic device for plastic film packaging bags. Background Technology

[0002] Product sealing and packaging requires plastic film bags. These bags are stored by being wound onto a roll, forming a tape roll. Therefore, the two layers of film on the bag are tightly adhered together. The bag should be opened before the product is placed inside. However, plastic films are prone to static electricity, making it difficult to fully separate the two layers and increasing the difficulty of opening the bag. Summary of the Invention

[0003] The purpose of this invention is to provide an antistatic device for plastic film packaging bags, so as to solve the problem that plastic film packaging bags are difficult to open due to static electricity.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: an antistatic device for plastic film packaging bags, which is installed between a bag feeding mechanism and a bag opening mechanism. The bag feeding mechanism is used to feed plastic film packaging bags to the bag opening mechanism, which is used to open the packaging bags. The antistatic device includes a nozzle assembly, which includes an air inlet and a plurality of nozzles connected to the air inlet. The air inlet of the nozzle assembly is connected to an ion fan. The ion fan sprays ionized air through the nozzles of the nozzle assembly. The ionized air sprayed by the ion fan contains ions to reduce the static electricity attached to the plastic film packaging bags, so that the bag opening mechanism can open the plastic film packaging bags.

[0005] In one embodiment, the nozzle assembly has an air inlet duct, the air inlet is disposed at one end of the air inlet duct, and the nozzles are arranged at intervals along the axial direction of the air inlet duct.

[0006] In one embodiment, the direction in which the plastic film packaging bag is conveyed from the bag feeding mechanism to the bag opening mechanism is defined as its length direction, the opening of the plastic film packaging bag is located on one side in its width direction, and the air inlet pipe is located on the side biased towards the opening along the width direction of the plastic film packaging bag.

[0007] In one embodiment, the air inlet duct extends along the width of the plastic film packaging bag.

[0008] In one embodiment, the end of the bag feeding mechanism is provided with a bag opening piece, which is used to be positioned between the two layers of film of the plastic film packaging bag and biased towards the side where the opening is located. The nozzle is positioned below the bag opening piece and facing the bag opening piece.

[0009] In one embodiment, the static eliminator is disposed below the plastic film packaging bag, with the nozzle facing upwards.

[0010] The beneficial effects of this utility model are: by setting the static electricity elimination device between the bag feeding mechanism and the bag opening mechanism, the ion fan blows out air with ions to neutralize the ions attached to the plastic film packaging bag, thereby reducing the static electricity attached to the plastic film packaging bag, so that the bag opening mechanism can open the plastic film packaging bag.

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] See Figures 1 to 4As shown, this utility model discloses an antistatic device for plastic film packaging bags. The antistatic device 10 is positioned between a bag feeding mechanism 20 and a bag opening mechanism 30. The bag feeding mechanism 20 feeds plastic film packaging bags 100 to the bag opening mechanism 30, which opens the packaging bag 100. Only the opening tab 301 is shown in the figure. The opening tab 301 is located at the end of the bag feeding mechanism 20 and is positioned between the two layers of film of the plastic film packaging bag 100, biased towards the side where the opening of the plastic film packaging bag 100 is located. The opening tab 301 can open the opening of the plastic film packaging bag 100 by a gap, facilitating subsequent opening clamps or suction nozzles to further open the packaging bag 100. The opening clamps or suction nozzles for opening the packaging bag opening are existing technologies and will not be described in detail here.

[0019] The static eliminator 10 includes a nozzle assembly 1, which includes an air inlet 11 and a plurality of nozzles 12 connected to the air inlet 11. The air inlet 11 of the nozzle assembly 1 is connected to an ion fan (not shown in the figure). The ion fan sprays out ion wind through the nozzles 12 of the nozzle assembly 1. The ion wind sprayed by the ion fan contains ions. By neutralizing the static electricity of the plastic film packaging bag 100 with the charged ions in the ion wind, the static electricity attached to the plastic film packaging bag 100 can be reduced, so that the bag opening mechanism 30 can open the plastic film packaging bag 100.

[0020] In this embodiment, the nozzle 12 of the nozzle assembly 1 is located below the bag opening piece 301. The nozzle 12 blows ion wind toward the plastic film packaging bag 100 at the location of the bag opening piece 301, so that the bag opening piece 301 can separate the two layers of film of the plastic film packaging bag 100.

[0021] In other embodiments, the static eliminator 10 can also be located at other positions between the bag feeding mechanism 20 and the bag opening mechanism 30, as long as it can reduce or even eliminate the static electricity attached to the plastic film packaging bag 100 to facilitate the bag opening mechanism 30 opening the plastic film packaging bag 100. Preferably, the static eliminator 10 is located below the plastic film packaging bag 100, with the nozzle 12 facing upwards. This allows the ion wind to blow upwards, and when the ion wind encounters the plastic film packaging bag 100, it can diffuse and increase the static eliminator range. On the other hand, it allows the space below the plastic film packaging bag 100 to be used to arrange the static eliminator 10, leaving the space above the plastic film packaging bag 100 for easy maintenance of the packaging equipment.

[0022] The nozzle assembly 1 has an air inlet pipe, an air inlet 11 is located at one end of the air inlet pipe, and nozzles 12 are arranged at intervals along the axial direction of the air inlet pipe. The other end of the air inlet pipe is fixedly connected to the fixing plate 40 by bolts. The direction in which the plastic film packaging bag 100 is conveyed from the bag feeding mechanism 20 to the bag opening mechanism 30 is defined as the length direction of the plastic film packaging bag 100. The opening of the plastic film packaging bag 100 is located on one side in its width direction, and the air inlet pipe is located on the side biased towards the opening along the width direction of the plastic film packaging bag 100. Thus, the nozzles 12 can blow ionizing air into the area where the opening of the plastic film packaging bag 100 is located, preferentially canceling the static electricity at the opening of the plastic film packaging bag 100. In this embodiment, the air inlet pipe extends along the width direction of the plastic film packaging bag 100. In other embodiments, it may also extend obliquely relative to the width direction of the plastic film packaging bag 100 or extend along the length direction of the plastic film packaging bag 100.

[0023] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
