AI Technical Summary
Existing antistatic devices for processing plastic packaging bags are difficult to adjust their position according to the width of the bag, resulting in some areas not being completely neutralized by static electricity. Furthermore, the bags are prone to slipping during clamping, causing surface scratches or tears.
The position of the ion air bar is adjusted by a motor-driven bidirectional threaded rod and slider system. Combined with an electric telescopic rod and clamping plate structure, it ensures uniform coverage of the ion air and prevents slippage. The ion air generated by the ion pump neutralizes static electricity. Rubber strips are used to increase friction and prevent slippage when the electric telescopic rod clamps the bar.
This technology allows for adjustment of the ion air coverage area based on the bag width, improving the antistatic effect while preventing damage during clamping, thus enhancing product quality and structural integrity.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic packaging bag processing technology, specifically to an antistatic device for processing plastic packaging bags. Background Technology
[0002] During the production of plastic packaging bags, static electricity is easily generated due to friction, extrusion, and peeling of the plastic material. For example, in the extrusion molding process of plastic film, the friction between the molten plastic and the surface of the equipment as it passes through the die generates a large amount of static electricity. If this static electricity is not eliminated in time, it will not only affect the subsequent processing of the plastic packaging bags.
[0003] The existing technology has the following defects or problems: Existing technology, publication number CN220576735U, discloses an antistatic device for processing plastic packaging bags, relating to the field of plastic packaging bag processing technology. It includes a main body with a door at the front, a controller positioned above the right side of the door, and a flattening device inside the main body. A water tank is located on the left side of the flattening device, and a humidifying device is located on the left side of the water tank. Compared to existing ordinary antistatic devices for processing plastic packaging bags, this antistatic device observes the thickness of the plastic packaging bag body and controls the controller to retract an electric telescopic rod, causing the electric telescopic rod to move. This moves a fixed cylinder, causing a change in the position of a second roller on the fixed cylinder, thus changing the distance between the second roller and the first roller. This facilitates flattening the plastic packaging bag body, improving the processing effect of subsequent devices.
[0004] The aforementioned equipment, during use, is difficult to adjust its position according to the width of the plastic packaging bag and the actual situation, resulting in some areas of static electricity not being completely neutralized, thus affecting the overall anti-static effect. Furthermore, in existing technologies, some anti-static devices used for processing plastic packaging bags may slip during the clamping process, coming into contact with the edges of the equipment or other hard objects. This can cause scratches, tears, or deformation on the surface of the packaging bag. These physical damages not only affect the appearance quality of the product but also weaken the structural integrity of the packaging bag, making it more prone to breakage during subsequent use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an antistatic device for processing plastic packaging bags, comprising a shell, a support plate fixedly connected to the left side of the shell, a motor fixedly connected to the top of the support plate, a bidirectional threaded rod fixedly connected to the drive end of the motor, two sliders connected to the external threads of the bidirectional threaded rod, ion pumps fixedly connected to the top ends of the two sliders respectively, ion pumps fixedly connected to the output ends of the two ion pumps respectively, an movable box fixedly connected inside the left side of the shell, a display screen provided at the front left side of the shell, an observation window fixedly connected to the front right side of the shell, multiple support legs fixedly connected to the bottom of the shell, and a conveying assembly fixedly connected to the top of the shell.
[0008] As a preferred embodiment of the present invention, the conveying assembly includes a motor two fixedly connected inside a protective box, a rotating shaft fixedly connected to the drive end of the motor two, a connecting plate fixedly connected to the bottom end of the rotating shaft, multiple connecting plates fixedly connected to the outside of the connecting plates, a connecting column fixedly connected to the opposite side of the multiple connecting plates, and multiple clamping assemblies fixedly connected to the bottom end of the connecting column.

[0010] As a preferred embodiment of this utility model, the two sliders are externally slidably connected to the inner wall of the movable box, and the bidirectional threaded rod is externally rotatably connected to the inner walls of the left and right sides of the movable box.

[0014] Compared with the prior art, this utility model provides an antistatic device for processing plastic packaging bags, which has the following beneficial effects:
[0015] 1. An antistatic device for processing plastic packaging bags, comprising a motor, a bidirectional threaded rod, sliders, an ion pump, an ion air bar, and a movable box. After the motor is started, its drive end drives the bidirectional threaded rod to rotate. Since the bidirectional threaded rod has two sections of threads with opposite directions of rotation, the two sliders will move relative to or away from each other along the bidirectional threaded rod under the action of the threads. When the sliders move, the ion pump and ion air bar connected to them also move accordingly, so that the position of the ion air bar can be adjusted according to the actual width of the plastic packaging bag, ensuring that the ion air can evenly cover the entire surface of the plastic packaging bag, thereby improving the antistatic effect.
[0016] 2. An antistatic device for processing plastic packaging bags, comprising an electric telescopic rod, a sliding plate, a fixed block, a movable groove, a protrusion, a sliding column, a clamping plate, and rubber strips. When the electric telescopic rod is activated, it extends, pushing the connected sliding plate into the movable groove of the fixed block. As this sliding plate moves, it pushes the protrusion it contacts, causing the protrusion to slide on the sliding column, thereby driving the other sliding plate to move synchronously. The two sliding plates move towards each other, bringing the clamping plates closer together and clamping the plastic packaging bag tightly. The rubber strips on the inner side of the clamping plates increase friction, preventing the plastic packaging bag from slipping during clamping and also preventing direct contact between the clamping plates and the packaging bag, thus avoiding damage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Example 1
[0024] Please see Figure 1-4 In this embodiment: an antistatic device for processing plastic packaging bags includes a housing 1, a support plate 2 fixedly connected to the left side of the housing 1, a motor 3 fixedly connected to the top of the support plate 2, a bidirectional threaded rod 4 fixedly connected to the drive end of the motor 3, a bidirectional threaded rod 4 rotatably connected to the left outer side of the left inner wall of the housing 1, and a bidirectional threaded rod 4 rotatably connected to the left and right inner walls of the movable box 5, two sliders 6 threadedly connected to the outside of the bidirectional threaded rod 4, the two sliders 6 slidably connected to the outside of the movable box 5, an ion pump 7 fixedly connected to the top of each of the two sliders 6, an ion fan bar 8 fixedly connected to the output end of each of the two ion pumps 7, a movable box 5 fixedly connected to the inside of the left side of the housing 1, a bottom end of the movable box 5 fixedly connected to the bottom inner wall of the left side of the housing 1, a display screen 9 provided at the front left side of the housing 1, an observation window 10 fixedly connected to the front right side of the housing 1, multiple support legs 11 fixedly connected to the bottom of the housing 1, and a conveying assembly fixedly connected to the top of the housing 1.
[0025] In this embodiment, when the device is turned on, the ion pump 7 starts working, ionizing molecules in the air to generate a large number of ions with positive and negative charges. These ions are blown out by the ion wind bar 8 to form an ion wind, which can neutralize the static charge on the surface of the plastic packaging bag, thus achieving the purpose of removing static electricity; after the motor 3 starts, its drive end drives the bidirectional threaded rod 4 to rotate. Because the bidirectional threaded rod 4 has two sections of threads with opposite directions of rotation, the two sliders 6 move relative to or away from each other along the bidirectional threaded rod 4 under the action of the threads. When the sliders 6 move, the ion pump 7 and ion air bar 8 connected to them also move accordingly, allowing the ion air bar 8 to adjust its position according to the actual situation such as the width of the plastic packaging bag, ensuring that the ion air can evenly cover the entire surface of the plastic packaging bag, thereby improving the static elimination effect. For wider plastic packaging bags, the bidirectional threaded rod 4 can be rotated by the motor 3, causing the two ion air bars 8 to move to both sides, expanding the static elimination range. For narrower plastic packaging bags, the ion air bars 8 are brought closer together to concentrate on the effective area for static elimination treatment. The display screen 9 can display the working parameters of the ion pump 7 in real time, such as the concentration of output ions and the intensity of the ion air. Operators can judge the operating status of the device and whether the static elimination effect is good based on these parameters. At the same time, through the observation window 10, operators can intuitively see the conveying of the plastic packaging bag inside the device and the relative position of the ion air bar 8 and the plastic packaging bag, facilitating timely adjustment of equipment operating parameters.
[0026] Example 2
[0027] like Figure 1 - Figure 4As shown, the conveying assembly includes a protective box 12, the bottom of which is fixedly connected to the top of the outer shell 1. A second motor 13 is fixedly connected inside the protective box 12. A rotating shaft 14 is fixedly connected to the drive end of the second motor 13. The rotating shaft 14 is rotatably connected to the inner wall of the top of the outer shell 1. A connecting plate 15 is fixedly connected to the bottom of the rotating shaft 14. Multiple connecting plates 15 are fixedly connected to the outside of the connecting plate 15. A connecting post 16 is fixedly connected to the opposite side of the multiple connecting plates 15. Multiple clamping assemblies are fixedly connected to the bottom of the connecting post 16. The multiple clamping assemblies include fixing blocks 18. The tops of the multiple fixing blocks 18 are respectively fixedly connected to the bottom perimeter of the outer ring 17. Movable grooves are formed inside the fixing blocks 18. 19. An electric telescopic rod 20 is fixedly connected to the front side of the fixing block 18. Two sliding plates 21 are provided inside the fixing block 18. The adjacent sides of the two sliding plates 21 are in contact with the distant sides of the two protrusions 25 respectively. The front side of one of the sliding plates 21 is fixedly connected to the output end of the electric telescopic rod 20. A limiting plate 22 is fixedly connected to the bottom end of the fixing block 18. A sliding groove 23 is provided at the top of the limiting plate 22. Sliding columns 24 are fixedly connected to the front and rear sides of the sliding groove 23. Protrusions 25 are slidably connected to the outside of the sliding columns 24. A return spring 26 is sleeved on the outside of the sliding columns 24. Clamping plates 27 are fixedly connected to the bottom ends of the two sliding plates 21. Multiple rubber strips 28 are fixedly connected to the adjacent sides of the two clamping plates 27 respectively.
[0028] In this embodiment, when it is necessary to clamp the plastic packaging bag, the electric telescopic rod 20 is activated. The electric telescopic rod 20 extends, pushing the slide plate 21 connected to it to slide within the movable groove 19 of the fixed block 18. As this slide plate 21 moves, it pushes the protrusion 25 in contact with it. The protrusion 25 slides on the sliding column 24, thereby driving the other slide plate 21 to move synchronously. The two slide plates 21 move towards each other, causing the clamping plates 27 to come closer together, thereby clamping the plastic packaging bag. The rubber strip 28 on the inner side of the clamping plate 27 can increase the friction, preventing the plastic packaging bag from slipping during clamping, and also avoiding direct contact between the clamping plate 27 and the packaging bag, which could cause damage. When the electric telescopic rod 20 retracts, under the action of the return spring 26, the protrusion 25 drives the slide plate 21 to return to its original position, and the clamping plate 27 releases the plastic packaging bag. After the motor 13 starts, its drive end drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 causes the connecting plate 15 connected to its bottom end to rotate around the axis, thereby driving the connecting column 16 and the outer ring 17 at the bottom end of the connecting column 16 and the clamping assembly to perform circular motion. When the clamping assembly clamps the plastic packaging bag and performs circular motion, the plastic packaging bag is conveyed in the device. During the conveying process, the conveying speed of the plastic packaging bag can be adjusted by controlling the rotation speed of the rotating shaft 14 through the motor 13 to adapt to different antistatic process requirements. For example, for some plastic packaging bags with high requirements for antistatic effect, the conveying speed can be reduced to allow the ion wind more time to neutralize the static electricity on the surface of the packaging bag; while for some cases with high production efficiency requirements and relatively low requirements for antistatic effect, the conveying speed can be appropriately increased.
[0029] The working principle and usage process of this utility model are as follows: When it is necessary to clamp a plastic packaging bag, firstly, the electric telescopic rod 20 is activated, and the electric telescopic rod 20 extends, pushing the slide plate 21 connected to it to slide within the movable groove 19 of the fixed block 18. As this slide plate 21 moves, it pushes the protrusion 25 in contact with it, and the protrusion 25 slides on the sliding column 24, thereby driving the other slide plate 21 to move synchronously. The two slide plates 21 move towards each other, causing the clamping plates 27 to come closer together, thereby clamping the plastic packaging bag; then, the motor 13 is activated, and its drive end drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 causes the connecting plate 15 connected to its bottom end to rotate around the axis, thereby driving the connecting column 16 and the outer ring 17 at the bottom end of the connecting column 16 and the clamping assembly to perform circular motion. When the clamping component holds the plastic packaging bag and moves in a circular motion, the plastic packaging bag is transported within the device. During the transport process, it passes through the ion air bar 8, and the ion pump 7 starts working. The ion pump 7 ionizes the molecules in the air, generating a large number of ions with positive and negative charges. These ions are blown out through the ion air bar 8 to form an ion wind. The ion wind can neutralize the static charge on the surface of the plastic packaging bag, thus achieving the purpose of removing static electricity.
