Description

Technical Field

[0001] This utility model relates to the field of antistatic polymer material testing technology, and in particular to an antistatic testing device for antistatic polymer materials. Background Technology

[0002] Antistatic polymer materials are functional materials that impart antistatic capabilities to traditional polymer materials (such as plastics, rubber, and fibers) through specific technologies (such as adding antistatic agents and composite conductive fillers). Their core function is to inhibit or eliminate the accumulation of static charge on the surface and inside the material, thereby solving various hazards or performance defects caused by static electricity.

[0003] An investigation revealed that patent CN211697639U discloses an antistatic testing device for antistatic polymer materials, comprising a base, a frame plate vertically welded to one side of the upper panel of the base, a mounting seat bolted to one side panel of the frame plate, the mounting seat being mounted on an electrostatic generator, an electrostatic emission rod fixedly connected to the electrostatic output end of the electrostatic generator, a contact head connected to the end of the electrostatic emission rod away from the electrostatic generator via an extension spring assembly, an antistatic insulating pad provided on the upper side panel of the base corresponding to the contact head, an antistatic insulating plate fixedly adhered to the upper side panel of the base on one side of the antistatic insulating pad, a metal plate fixedly connected to the antistatic insulating plate by several screws, and a contact plate connected to the side of the metal plate near the contact head via several buffer springs. This utility model has a novel structure, is easy to use, and is a new and practical antistatic testing device for antistatic polymer materials.

[0004] This patent actively applies static electricity to antistatic polymer materials, avoiding situations where the surface static electricity of the antistatic polymer material is too weak to be detected. However, this patent uses an electrostatic detector that can only test one sample of antistatic polymer material per test cycle. After each test, the antistatic polymer material needs to be picked up and replaced, and the electrostatic detector needs to be restarted, which is cumbersome and inefficient. Therefore, this paper proposes an antistatic testing device for antistatic polymer materials to meet the application requirements. Utility Model Content

[0005] The purpose of this invention is to provide an antistatic testing device for antistatic polymer materials to solve the problems mentioned in the background art.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the rotation of the dial block drives the radial groove to rotate the grooved wheel. One rotation of the dial block causes the grooved wheel to rotate a quarter turn, which in turn drives the detection head to rotate a quarter turn to detect untested antistatic polymer materials. A single detection process can detect multiple antistatic polymer materials, resulting in high detection efficiency.

[0015] In this invention, the rotation of the drive motor causes a pair of fixing bars to move and move closer together, clamping and fixing the electrostatic detector body, thus quickly securing the electrostatic detector body. Reversing the drive motor causes the pair of fixing bars to release the electrostatic detector body, disassembling and separating the wires from the detection head, enabling rapid disassembly of the electrostatic detector body and facilitating its disassembly and maintenance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] like Figure 1-4As shown, this embodiment provides an antistatic testing device for antistatic polymer materials, including an antistatic detector body 1 and a testing base 2. A wire 3 is installed on the antistatic detector body 1, and a testing head 4 is installed on the wire 3. A testing slot 5 is formed on the testing base 2. A switching shaft 6 is rotatably installed inside the testing base 2, and a switching plate 7 is installed on the switching shaft 6. The antistatic detector body 1 is placed on the switching plate 7. A fixing strip 8 is adjustablely installed on the switching plate 7, and a contact pad 9 is installed inside the fixing strip 8. A protective shell 10 is installed on the testing base 2. Different antistatic polymer materials to be tested are placed in multiple testing slots 5, with each antistatic polymer material corresponding to a single testing slot 5. A pair of fixing strips 8 move and move closer to each other to clamp and fix the antistatic detector body 1. The contact pad 9 directly contacts the antistatic detector body 1, preventing damage to the antistatic detector body 1 from clamping, thus achieving fixation of the antistatic detector body 1 and preventing it from falling off the testing base 2 during carrying or use.

[0024] When the electrostatic detector body 1 malfunctions and requires repair, the pair of fixing bars 8 can be driven to loosen the electrostatic detector body 1. At this point, the electrostatic detector body 1 can be directly lifted upwards, and the lead wire 3 can be disassembled from the detection head 4, enabling quick disassembly of the electrostatic detector body 1 and facilitating its disassembly and repair. During testing, the device is connected to an external power source. The detection head 4 descends to test the antistatic polymer material in the detection tank 5, and the test data is recorded by the electrostatic detector body 1. After testing a single antistatic polymer material, the switching shaft 6 and switching disk 7 rotate a quarter turn, which drives the detection head 4 to rotate a quarter turn to test the untested antistatic polymer materials. A single testing process can test multiple antistatic polymer materials, resulting in high testing efficiency.

[0025] To drive the detection head 4 to rotate a quarter turn to test the untested antistatic polymer material, a grooved wheel 11 is fixedly sleeved on the switching shaft 6. The grooved wheel 11 has a radial groove 12. A rotating rod 13 is rotatably mounted at the bottom of the switching disk 7. A lever 14 is installed on the rotating rod 13. The grooved wheel 11 and the lever 14 are movably engaged. A shifting motor 16 is installed on the detection base 2. A drive shaft 17 is installed at the output end of the shifting motor 16. The rotating rod 13 is installed on the drive shaft 17. The rotation of the shifting motor 16 will drive the drive shaft 17 to rotate. The rotation of the drive shaft 17 will drive the rotating rod 13 and the lever 14 to rotate. The rotation of the lever 14 will drive the grooved wheel 11 to rotate through the radial groove 12. One rotation of the lever 14 will drive the grooved wheel 11 to rotate a quarter turn, which will drive the switching shaft 6 and the switching disk 7 to rotate a quarter turn, and thus drive the detection head 4 to rotate a quarter turn to test the untested antistatic polymer material.

[0026] A locking block 15 is installed on the rotating rod 13, and the locking block 15 and the grooved wheel 11 are in movable cooperation. In addition, when the shifting motor 16 stops, the arc surface of the locking block 15 contacts the arc groove of the grooved wheel 11, which can overcome the rotational inertia of the grooved wheel 11 and realize accurate shifting detection. When the toggle block 14 moves the radial groove 12, the notch of the locking block 15 does not contact the arc groove of the grooved wheel 11, and does not affect the toggle of the grooved wheel 11.

[0027] To quickly fix the electrostatic detector body 1 by driving a pair of fixing strips 8, a support plate 18 is installed on the detection base 2. A double-ended screw 19 is rotatably installed inside the support plate 18. The fixing strips 8 are screwed onto the double-ended screw 19. A drive motor 20 is installed on the support plate 18, and the double-ended screw 19 is installed at the output end of the drive motor 20. The rotation of the drive motor 20 will drive the double-ended screw 19 to rotate. The rotation of the double-ended screw 19 will drive the pair of fixing strips 8 to move and move closer to each other to clamp and fix the electrostatic detector body 1. The contact pad 9 directly contacts the electrostatic detector body 1 to avoid damage to the electrostatic detector body 1 caused by clamping, thereby achieving the fixation of the electrostatic detector body 1.

[0028] In order to guide the movement of the fixing strip 8, a guide frame 21 is installed on the detection base 2, and the fixing strip 8 is slidably sleeved on the guide frame 21; the guide frame 21 can guide the movement of the fixing strip 8, so that the fixing strip 8 can only move along the guide frame 21.

[0029] To achieve accurate detection of antistatic polymer materials, an electric telescopic rod 22, an ultrasonic receiver 23, a microcontroller 25, and an ultrasonic transmitter 24 are respectively installed at the extension ends of the detection base 2 and the switching plate 7. The output end of the ultrasonic receiver 23 is installed on the detection head 4. In the initial stage, the ultrasonic transmitter 24 and the ultrasonic receiver 23 are aligned. At this time, the ultrasonic signal emitted by the ultrasonic transmitter 24 is received by the ultrasonic receiver 23, which transmits the signal to the microcontroller 25. The microcontroller 25 then controls the electrostatic detector body 1 and the electric telescopic rod 22 to open. The extension of the electric telescopic rod 22 lowers the detection head 4 to detect the antistatic polymer material in the detection tank 5. Similarly, when the ultrasonic transmitter 24 comes into contact with the ultrasonic receiver 23, the ultrasonic receiver 23 transmits the signal to the microcontroller 25, which then controls the switching motor 16 to stop, allowing the detection of undetected antistatic polymer materials and recording the data. This enables accurate detection of antistatic polymer materials.

[0030] Working Principle: During use, different antistatic polymer materials to be tested are placed in multiple testing slots 5, with each antistatic polymer material corresponding to a single testing slot 5. The drive motor 20 is then started. The rotation of the drive motor 20 drives the double-headed screw 19 to rotate, which in turn moves a pair of fixing strips 8 closer together, clamping and fixing the electrostatic detector body 1. The contact pad 9 directly contacts the electrostatic detector body 1, preventing damage from clamping and thus securing the electrostatic detector body 1, preventing it from falling off the testing base 2 during transport or use. When the electrostatic detector body 1 malfunctions and requires repair, the drive motor 20 can be reversed, causing the pair of fixing strips 8 to loosen the electrostatic detector body 1. The electrostatic detector body 1 can then be directly lifted upwards, and the wires 3 and testing head 4 can be disassembled and separated, enabling quick disassembly of the electrostatic detector body 1 for easy disassembly and repair. During testing, the device is connected to an external power source. In the initial stage, the ultrasonic transmitter 24 and ultrasonic receiver 23 are aligned. At this time, the ultrasonic signal emitted by the ultrasonic transmitter 24 is received by the ultrasonic receiver 23, which transmits the signal to the microcontroller 25. The microcontroller 25 then controls the electrostatic detector body 1 and the electric telescopic rod 22 to open. The extension of the electric telescopic rod 22 lowers the detection head 4 to test the antistatic polymer material in the detection tank 5, and the detection data is recorded by the electrostatic detector body 1. After the detection of a single antistatic polymer material is completed, the microcontroller 25 controls the start of the shift motor 16. The rotation of the shift motor 16 drives the drive shaft 17 to rotate, which in turn drives the rotating rod 13 and the toggle block 14 to rotate. The rotation of the toggle block 14 causes the groove wheel 11 to rotate through the radial groove 12. One rotation of the toggle block 14 causes the groove wheel 11 to rotate one-quarter of a turn, which in turn drives the switching shaft 6 and the switching disk 7 to rotate one-quarter of a turn, which in turn drives the detection head 4 to rotate one-quarter of a turn to test the untested antistatic polymer material. Similarly, when the ultrasonic transmitter 24 contacts the ultrasonic receiver 23, the ultrasonic receiver 23 transmits the signal to the microcontroller 25, which then controls the transposition motor 16 to stop, allowing for the detection and data recording of the previously undetected antistatic polymer materials. Furthermore, when the transposition motor 16 stops, the arc surface of the locking block 15 contacts the arc-shaped groove of the grooved wheel 11, overcoming the rotational inertia of the grooved wheel 11 and achieving precise transposition detection. When the toggle block 14 moves the radial groove 12, the notch of the locking block 15 does not contact the arc-shaped groove of the grooved wheel 11, thus not affecting the movement of the grooved wheel 11. Repeating this process, a single detection cycle can detect multiple antistatic polymer materials, resulting in high detection efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
