Description

Technical Field

[0001] The utility model relates to the technical field of antistatic detection, in particular to an antistatic detection device for heat shrinkable film. Background Art

[0002] POF shrink film is the abbreviation of biaxially oriented polyolefin shrink film. It is a new type of environmentally friendly shrink film that is currently the most widely used and developing rapidly in the world. This product adopts the advanced special process of biaxially oriented three-layer and five-layer melt coextrusion, and produces a soft shrink film with high transparency, high shrinkage rate, high toughness, excellent heat sealing performance, antistatic property, good cold resistance, safety and reliability.

[0003] Due to the thin thickness of the heat shrinkable film and the friction generated during production, the heat shrinkable film often carries a lot of static electricity. With the continuous development of electronic technology, people's requirements for the performance of heat shrinkable film used in the electronic field are getting higher and higher. Among them, a very crucial requirement is that it has an antistatic effect. Therefore, during the production process of the heat shrinkable film, we need to detect its antistatic performance. In order to better detect the antistatic performance of the heat shrinkable film, we can detect and compare the charging effects before and after the heat shrinkable film is triboelectrified. Therefore, an antistatic detection device for heat shrinkable film is proposed. Content of the Utility Model

[0008] Preferably, the number of the lead screw, the pulley and the threaded block is two groups, and the two groups of pulleys are connected by a belt.

[0009] Preferably, a gear is fixedly installed at one end of the rotating shaft, a rack is fixedly installed on the top surface of the workbench, and the gear is meshed with the rack.

[0010] Preferably, the fixing assembly includes a fixing frame fixedly installed on the top surface of the workbench. A threaded rod is installed inside the fixing frame in a threaded manner. A knob is fixedly installed at the top end of the threaded rod, and a pressing plate is rotatably installed at the bottom end of the threaded rod.

[0011] Preferably, a limiting rod is fixedly installed on the top surface of the pressing plate, and the limiting rod is slidably connected to the fixing frame.

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

The output end of the driving component is fixedly installed with a moving frame 7. A rotating shaft 8 is rotatably installed inside the moving frame 7. A rubber rod 9 is fixedly installed on the surface of the rotating shaft 8. An installation frame 17 is fixedly installed on the top surface of the workbench 1. An electrostatic detector 18 is fixedly installed on the top surface of the installation frame 17. A connecting wire 19 is fixedly installed on the surface of the electrostatic detector 18. One end of the connecting wire 19 is fixedly installed with a detection head 20. An adjusting component is arranged on the bottom surface of the installation frame 17. The adjusting component includes an electric push rod 21 fixedly installed on the bottom surface of the installation frame 17. The output end of the electric push rod 21 is fixedly installed with a connecting rod 22, and the connecting rod 22 is fixedly connected with the detection head 20. Through the setting of the adjusting component, the electric push rod 21 drives the connecting rod 22 to move downward, so that the detection head 20 moves downward and approaches the heat shrinkable film fixed on the workbench 1 for electrostatic detection.

[0020] Specifically, a driving component is arranged inside the workbench 1. The driving component includes a driving motor 2 fixedly installed on the left side of the workbench 1. The output end of the driving motor 2 is fixedly installed with a lead screw 3. One end of the lead screw 3 is fixedly installed with a pulley 4. A belt 5 is arranged on the surface of the pulley 4. A threaded block 6 is threadedly installed on the surface of the lead screw 3. The number of the lead screw 3, the pulley 4 and the threaded block 6 is two groups, and the two groups of pulleys 4 are connected by the belt 5. One end of the rotating shaft 8 is fixedly installed with a gear 10. A rack 11 is fixedly installed on the top surface of the workbench 1, and the gear 10 and the rack 11 are meshed. Through the setting of the driving component, the output end of the driving motor 2 rotates, driving the lead screw 3 to rotate, so that the pulley 4 rotates. Under the action of the belt 5, the two lead screws 3 rotate, thereby driving the threaded block 6 to move, so that the moving frame 7 moves, and then driving the rubber rod 9 to move. And the gear 10 and the rack 11 are meshed. As the moving frame 7 moves, the gear 10 rotates, and then drives the rubber rod 9 to rotate, so that the rubber rod 9 rubs against the heat shrinkable film to generate static electricity.

[0021] Specifically, a fixing component is provided on the top surface of the workbench 1. The fixing component includes a fixing frame 12 fixedly installed on the top surface of the workbench 1. A threaded rod 13 is installed inside the fixing frame 12 in a threaded manner. A knob 14 is fixedly installed at the top end of the threaded rod 13.

A limiting rod 16 is fixedly installed on the top surface of the pressing plate 15, and the limiting rod 16 is slidably connected to the fixing frame 12. Through the setting of the fixing component, by rotating the knob 14, the threaded rod 13 is driven to rotate, so that the pressing plate 15 moves downward, and the heat shrinkable film can be tightly fixed. Through the setting of the limiting rod 16, the pressing plate 15 can be limited, so that the up and down movement of the pressing plate 15 is more stable.

[0022] All the electrical components appearing in this article are electrically connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0023] During use: Place the heat shrinkable film on the workbench 1. Rotate the knob 14 to drive the threaded rod 13 to rotate, so that the pressing plate 15 moves downward, and the heat shrinkable film can be tightly fixed. Start the static electricity detector 18 and the electric push rod 21. The electric push rod 21 drives the connecting rod 22 to move downward, so that the detection head 20 moves downward and approaches the heat shrinkable film fixed on the workbench 1 for static electricity detection. Start the drive motor 2. Through the rotation of the output end of the drive motor 2, the lead screw 3 is driven to rotate, so that the pulley 4 rotates. Under the action of the belt 5, the two lead screws 3 rotate, and then the threaded block 6 moves, so that the moving frame 7 moves, and then the rubber rod 9 moves. And the gear 10 and the rack 11 are meshed. As the moving frame 7 moves, the gear 10 rotates, and then the rubber rod 9 rotates, so that the rubber rod 9 rubs against the heat shrinkable film to generate static electricity. Start the electric push rod 21 again, drive the connecting rod 22 to move downward, so that the detection head 20 moves downward and approaches the heat shrinkable film fixed on the workbench 1 again for static electricity detection. Compare the two sets of data. If the amount of static electricity attached to the surface of the heat shrinkable film detected after friction does not change much, it means that the antistatic effect of the heat shrinkable film is better. Otherwise, it means that the antistatic effect of the heat shrinkable film is worse.
