Description

Technical Field

[0001] This utility model relates to the field of antistatic masterbatch production technology, and in particular to a surface resistivity testing device for antistatic masterbatch production. Background Technology

[0002] Antistatic masterbatch is a functional additive used to reduce the surface resistance of materials and prevent the adverse effects of static electricity. Antistatic masterbatch is a bipolar substance that can migrate to the surface of materials, absorb moisture from the air, form a conductive layer, and dissipate the accumulated charge in a timely manner, thereby having the ability to control the charge. During the production of antistatic masterbatch, its surface resistivity needs to be tested, which requires the use of surface resistivity testing equipment for antistatic masterbatch production.

[0003] Currently, existing surface resistivity testing equipment for antistatic masterbatch production typically uses an electric heating plate press to compress the antistatic masterbatch into sheets, and then uses a parallel electrode probe to test the surface resistivity of the antistatic masterbatch.

[0004] However, similar surface resistivity testing equipment used in the production of antistatic masterbatch requires manual removal of the prepared antistatic masterbatch by staff before testing. During the removal process, dust easily adheres to the surface of the prepared antistatic masterbatch, resulting in inaccurate surface resistivity test results. Furthermore, manual measurement is cumbersome and reduces the efficiency of surface resistivity testing of antistatic masterbatch. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface resistivity testing device for antistatic masterbatch production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A surface resistivity testing device for antistatic masterbatch production includes a workbench. A base is fixedly connected to the bottom of the workbench, and a heating plate is fixedly installed on the top of the workbench. Multiple support rods are fixedly connected to the top of the workbench, and the tops of the multiple support rods are fixedly connected to the same top plate. A hydraulic cylinder is fixedly connected to the top of the top plate, and a pressure plate is fixedly connected to the piston end of the hydraulic cylinder. Two connecting holes are opened on the top of the pressure plate, and movable rods are inserted into the inner walls of the connecting holes. An installation groove is opened at the bottom of the movable rod, and a guide rod is fixedly connected to the top inner wall of the installation groove. A probe is installed at the bottom end of the guide rod.

[0008] The present invention is further configured such that a display is fixedly connected to the top of the top plate, and the display is electrically connected to the guide rod.

[0009] The present invention is further configured such that a connecting frame is fixedly connected between the two movable rods.

[0010] The present invention is further configured such that two return springs are fixedly connected between the connecting frame and the pressure plate, and the two return springs are respectively sleeved on the outer wall of the two movable rods.

[0011] The present invention is further configured such that two limiting holes are provided on the top of the top plate, and limiting rods are inserted into the inner walls of the limiting holes, and the limiting rods are fixedly connected to the pressure plate.

[0012] The present invention is further configured such that a limiting plate is fixedly connected to the top of the limiting rod.

[0013] The present invention is further provided with a gasket on the opposite side of the pressure plate and the worktable, and the gasket is made of polytetrafluoroethylene dispersion resin.

[0014] The present invention is further configured such that the upper gasket has two movable holes, the movable holes corresponding to the connecting holes.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This surface resistivity testing equipment for antistatic masterbatch production, when testing the surface resistivity of antistatic masterbatch, first places the antistatic masterbatch in the middle of the workbench, then heats the antistatic masterbatch with a heating plate, and then drives the pressure plate to move down through a hydraulic cylinder to press the antistatic masterbatch into a sheet. Then, the operator presses the movable rod, which pushes the probe down so that the two probes come into contact with the antistatic masterbatch sheet, thereby detecting the resistivity of the antistatic masterbatch. The operation is simple and avoids the problem of dust adhering to the antistatic masterbatch sheet during the testing process, which affects the test results.

[0017] 2. The surface resistivity testing equipment for antistatic masterbatch production can press the connecting frame when performing resistivity testing on antistatic masterbatch sheets. The connecting frame drives two movable rods to move down simultaneously, quickly performing surface resistivity testing on the antistatic masterbatch. At the same time, after the test is completed, the probe can be quickly pushed to separate from the antistatic masterbatch by the elastic force of the reset spring.

[0018] 3. The surface resistivity testing equipment for antistatic masterbatch production is equipped with a gasket made of polytetrafluoroethylene dispersion resin, which effectively prevents the antistatic masterbatch sheets from sticking to the workbench and pressure plate during the pressing process, making it easier to use.

The probe 17 is a parallel electrode probe.

[0029] Reference Figure 1 and Figure 4 A display 6 is fixedly connected to the top of the top plate 4. The display 6 is electrically connected to the guide rod 16. The surface resistivity of the antistatic masterbatch can be quickly displayed through the display 6. A connecting frame 11 is fixedly connected between the two movable rods 14. The connecting frame 11 facilitates the synchronous pressing of the two movable rods 14. Two return springs 18 are fixedly connected between the connecting frame 11 and the pressure plate 10. The two return springs 18 are respectively sleeved on the outer wall of the two movable rods 14. The elastic force of the return springs 18 facilitates the push of the two movable rods 14 to return to their original positions.

[0030] Reference Figure 1 and Figure 2 The top plate 4 has two limiting holes 7. A limiting rod 8 is inserted into the inner wall of the limiting hole 7.
