Description

Technical Field

[0001] This utility model relates to the field of electrostatic detection technology for coated film surfaces, and in particular to a positioning and detection frame for real-time monitoring of electrostatic values ​​on film surfaces. Background Technology

[0002] During the production of coated films, such as extrusion, coating, winding, or use, static electricity is generated due to material friction and separation, leading to the accumulation of static charge on the film surface. The core of static electricity detection is to measure the static voltage, surface potential, or charge density of the film surface using specialized equipment to reflect the strength of static electricity accumulation. Static electricity detection of coated film surface is an important step in assessing the accumulation of static charge on the coated film surface, and it is of key significance for ensuring product quality, production safety, and subsequent processing performance.

[0003] The electrostatic voltage on the surface of the coated film changes with temperature and humidity. For example, high temperature and low humidity environments can easily lead to the accumulation of static electricity, while high humidity environments may cause the surface of the coated film to absorb moisture. Traditional testing racks are usually open and directly exposed in the production workshop for testing. However, the temperature and humidity in the workshop are not easy to control, which may affect the accuracy of the testing. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a real-time monitoring and positioning detection frame for electrostatic values ​​of the film surface, which aims to improve the problem that environmental factors affect the detection accuracy of coated films in traditional equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A real-time monitoring and positioning detection frame for electrostatic values ​​on membrane surfaces includes a base plate. A detection chamber is fixedly installed on the top surface of the base plate. Two telescopic frames are provided inside the detection chamber. An electric push rod is provided on the inner side of the telescopic frame, and the telescopic end of the electric push rod is connected to the telescopic frame, while the other end is fixedly connected to the inner wall of the detection chamber. A fixed seat is fixedly connected to the surface of the telescopic frame. An electrostatic detector is provided at the bottom of the fixed seat, and the electrostatic detector is fixed to the fixed seat through a disassembly assembly. A humidifier, a thermostat, and a temperature and humidity sensor are sequentially installed inside the detection chamber. A fan is provided inside the detection chamber. A moving groove is opened on the inner wall of the detection chamber. An adjustment assembly is provided inside the moving groove, and the adjustment assembly is connected to the fan.

[0007] Preferably, the disassembly assembly includes a pull plate, a tension spring, and a insert plate. The tension spring is embedded inside the fixed base, the pull plate is disposed on one side of the fixed base, and one end of the tension spring is connected to the pull plate. The insert plate is fixedly installed on one side of the pull plate.

[0008] Preferably, a mounting base is fixedly connected to one side of the electrostatic detector, and the mounting base extends into the interior of the fixed base. A slot is provided through the surface of the mounting base, and a plug plate is inserted into the interior of the slot. A handle is fixedly connected to one side of the pull plate.

[0009] Preferably, the adjusting assembly includes a screw, a movable block, a worm gear, and a worm. The screw is disposed inside the movable slot, the movable block is sleeved on the outside of the screw, and a fan is fixedly installed on one side of the movable block. The worm gear is fixedly installed at one end of the screw, and the worm is disposed on one side of the worm gear, and the worm and the worm gear are meshed together.

[0010] Preferably, the moving groove is provided with a guide rod inside, and the guide rod passes through the moving block. A first motor is installed on the top of the detection cavity, and the output end of the first motor is connected to the worm gear.

[0011] Preferably, the top surface of the base plate is sequentially equipped with an unwinding roller and a winding roller via a fixing frame, and the unwinding roller and the winding roller are arranged on both sides of the detection chamber.

[0013] Preferably, a disassembly plate is detachably installed on one side of the detection cavity via bolts.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up a detection chamber, which is a relatively sealed space, it is possible to regulate the temperature and humidity inside to meet the detection environment. At the same time, by sequentially setting a humidifier thermostat and a temperature and humidity sensor inside the detection chamber, the temperature and humidity inside the detection chamber can be detected and regulated in real time, avoiding the impact of environmental factors on the detection accuracy.

[0016] 2. In this utility model, by setting a fan, air can be blown into the detection chamber. The relatively gentle forced airflow can make the air temperature and humidity inside the detection chamber more evenly distributed, thereby further improving the detection environment. At the same time, with the adjustment component, the position of the fan can be changed, thereby enhancing the effect of uniform air temperature and humidity distribution.

[0027] 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.

[0028] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a real-time monitoring and positioning detection frame for electrostatic values ​​on a membrane surface, comprising a base plate 1, a detection cavity 3 fixedly mounted on the top surface of the base plate 1, two telescopic frames 15 inside the detection cavity 3, an electric push rod 18 inside the telescopic frame 15, the telescopic end of the electric push rod 18 being connected to the telescopic frame 15, and the other end being fixedly connected to the inner wall of the detection cavity 3, a fixed seat 16 being fixedly connected to the surface of the telescopic frame 15, an electrostatic detector 14 being provided at the bottom of the fixed seat 16, and the electrostatic detector 14 being fixed to the fixed seat 16 by a disassembly and assembly assembly, a humidifier 11, a thermostat 12 and a temperature and humidity sensor 13 being sequentially installed inside the detection cavity 3, a fan 10 being provided inside the detection cavity 3, a moving groove 8 being opened on the inner wall of the detection cavity 3, an adjustment assembly being provided inside the moving groove 8, and the adjustment assembly being connected to the fan 10.

[0029] Specifically, the detection chamber 3 has an inlet and an outlet on each side, allowing the coated film to extend into the chamber for detection. Two electrostatic detectors 14 are staggered, enabling detection of both sides of the coated film and increasing accuracy. The telescopic end of the electric push rod 18 is connected to the inner surface of the telescopic frame 15, allowing the electric push rod 18 to extend and retract, simultaneously raising and lowering the electrostatic detectors 14, ensuring contact between the electrostatic detectors 14 and the coated film being monitored. The device has been monitored in close proximity or contact. The temperature and humidity inside the detection chamber 3 can be adjusted by the humidifier 11 and the thermostat 12. This allows the temperature and humidity inside the detection chamber 3 to be adjusted to a level conducive to the monitoring of the coated film, thus avoiding the impact of environmental factors on the detection accuracy. At the same time, since the detection chamber 3 is a relatively sealed environment, the rapid loss of temperature and humidity can be reduced, ensuring the continuity of the detection. The thermostat 12 and humidifier 11 used in this device are commonly used devices that are widely used in various fields. Therefore, their specific models and principles will not be described in detail here.

[0030] Reference Figure 4 , Figure 5 and Figure 6 The assembly includes a pull plate 17, a tension spring 24, and an insert plate 25. The tension spring 24 is embedded inside the fixed base 16. The pull plate 17 is located on one side of the fixed base 16, and one end of the tension spring 24 is connected to the pull plate 17. The insert plate 25 is fixedly installed on one side of the pull plate 17. A mounting base 22 is fixedly connected to one side of the electrostatic detector 14, and the mounting base 22 extends into the interior of the fixed base 16. A slot 23 is provided through the surface of the mounting base 22, and the insert plate 25 is inserted into the interior of the slot 23. A handle 26 is fixedly connected to one side of the pull plate 17.

[0031] Specifically, the bottom of the fixing base 16 has a slot corresponding to the mounting base 22. When installing the electrostatic detector 14, the mounting base 22 can be inserted into the slot at the bottom of the fixing base 16. At this time, the slot 23 is positioned directly opposite the insertion plate 25. When the insertion plate 25 is inserted into the slot 23, the mounting base 22 can be fixed inside the fixing base 16, thus completing the installation of the electrostatic detector 14. To remove the electrostatic detector 14, the pull plate 17 can be pulled, which will move the insertion plate 25. Once the plate 25 is disengaged from the slot 23, the mounting base 22 can be released from its fixed state, making it easier to remove and maintain the electrostatic detector 14. This increases the convenience of removing, maintaining, and calibrating the electrostatic detector 14. When the pull plate 17 is pulled, the pull plate 17 can pull the tension spring 24. The tension spring 24 can pull the pull plate 17 in the opposite direction through its elastic potential energy, thereby ensuring the initial position of the pull plate 17 and ensuring the stability of the plate 25 inserted into the slot 23. This also ensures the stability of the electrostatic detector 14 installed at the bottom of the mounting base 16.

[0032] Reference Figure 1 and Figure 7 The adjustment assembly includes a screw 9, a moving block 19, a worm gear 20, and a worm 21. The screw 9 is located inside the moving groove 8. The moving block 19 is sleeved on the outside of the screw 9, and the fan 10 is fixedly installed on one side of the moving block 19. The worm gear 20 is fixedly installed on one end of the screw 9. The worm 21 is located on one side of the worm gear 20 and is meshed with the worm gear 20. A guide rod 27 is provided inside the moving groove 8 and passes through the moving block 19. A first motor 5 is installed on the top of the detection chamber 3, and the output end of the first motor 5 is connected to the worm 21.

[0033] Specifically, the screw 9 and the movable block 19 are connected by a copper drum thread. Therefore, when the screw 9 rotates, it can drive the movable block 19 to slide on the screw 9. At the same time, the guide rod 27 restricts the movement of the movable block 19, which increases the directionality and stability of the movement. Simultaneously, when the movable block 19 moves, it can drive the fan 10 to move inside the detection chamber 3. In actual use, the fan 10 can be turned on, and the fan 10 blows a gentle breeze into the detection chamber 3, which can accelerate the air circulation rate inside the detection chamber 3. This ensures the uniformity of the air temperature and humidity inside the detection chamber 3, thus ensuring the detection environment for the coated film.

[0034] It is worth noting that in actual use, if the temperature and humidity uniformity of the air inside the detection chamber 3 meets the detection conditions, the fan 10 can be turned off, thereby preventing the fan 10 from accelerating the air circulation rate and affecting the temperature and humidity uniformity.

[0035] Reference Figure 1 and Figure 2The top surface of the base plate 1 is sequentially equipped with an unwinding roller 2 and a winding roller 6 via a fixing frame. The unwinding roller 2 and the winding roller 6 are located on both sides of the detection chamber 3. The end of the winding roller 6 is fixedly equipped with a second motor 7 via a fixing frame, and the output end of the second motor 7 is connected to the winding roller 6. A disassembly plate 4 is detachably installed on one side of the detection chamber 3 via bolts.

[0036] Specifically, the coating film to be tested can be stably conveyed and tested through the take-up roller 6 and the unwind roller 2. By removing the bolts fixing the disassembly plate 4, the disassembly plate 4 can be removed from one side of the test chamber 3, thereby facilitating the maintenance of the components inside the test chamber 3.

[0037] Working principle: When using this device, it can be placed in a designated position, and the coating film to be tested can be extended into the interior of the detection chamber 3 and wrapped around the surface of the take-up roller 6. By turning on the second motor 7, the second motor 7 can drive the take-up roller 6 to rotate. The rotation of the take-up roller 6 can wind up the coating film to be tested, thereby conveying the coating film. During the test, the electric push rod 18 can be turned on, and the electric push rod 18 pushes the telescopic frame 15 to extend and retract. The telescopic frame 15 drives the electrostatic detector 14 to move, so that the electrostatic detector 14 moves to a suitable position, thereby ensuring that the electrostatic detector 14 can perform real-time detection of the coating film.

[0038] Before testing, the temperature and humidity inside the testing chamber 3 can be detected by the temperature and humidity sensor 13, and adjusted by turning on the thermostat 12 and the humidifier 11. This prevents environmental factors such as temperature and humidity from affecting the testing accuracy. By turning on the fan 10 and the first motor 5, the first motor 5 drives the worm gear 21 to rotate, the worm gear 21 drives the worm wheel 20 to rotate, the worm wheel 20 drives the screw 9 to rotate, the screw 9 drives the moving block 19 to move, and the moving block 19 drives the fan 10 to move. The fan 10 blows a gentle breeze into the testing chamber 3, which makes the temperature and humidity inside the testing chamber 3 more uniform and further ensures the best testing environment.

[0039] By removing the disassembly plate 4, the components inside the detection chamber 3 can be exposed. Pulling the handle 26 will pull the pull plate 17, which in turn moves the insertion plate 25, disengaging it from the slot 23. This releases the mounting base 22 from its fixed position, making it easier to remove the electrostatic detector 14. The removed electrostatic detector 14 can then be easily maintained and calibrated for future use. This equipment increases the accuracy of coating film detection while also making the disassembly and maintenance of the electrostatic detector 14 more convenient.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
