Description

Technical Field

[0001] The utility model relates to the technical field of viscometers, in particular to a viscometer for detecting water-based epoxy resins and curing agents. Background Art

[0002] Waterborne epoxy resins can be divided into anionic resins and cationic resins. Anionic resins are used for anodic electrodeposition coatings, and cationic resins are used for cathodic electrodeposition coatings. The main feature of waterborne epoxy resins is their excellent anti-corrosion properties. In addition to being used in automotive coatings, they are also used in medical devices, electrical appliances, and light industrial products. After processing, the viscosity of epoxy resins needs to be tested. Viscosity refers to the internal friction resistance generated by the fluid during the flow process. Its size is determined by factors such as the type of substance, temperature, and concentration. The viscosity of epoxy resins is often tested using a viscometer.

[0003] During use, existing viscometers require electronically driven detection rotor rotation to cause epoxy resin to flow inside the test cup. At this time, the test cup is easily affected by the viscosity of the epoxy resin, causing shaking, resulting in instability of the test cup, thereby affecting the detection of the epoxy resin and causing inaccurate test results. Utility Model Content

[0004] In response to the shortcomings of existing viscometers, the utility model provides a viscometer for testing water-based epoxy resins and curing agents. It has the advantages of being able to fix the test cup, improve the stability of the test cup, ensure that the epoxy resin can be tested under the same temperature environment, improve the detection accuracy, and solve technical problems such as the instability of the test cup.

[0005] The utility model provides the following technical solution: a viscometer for detecting water-based epoxy resin and curing agent, comprising a base and:

[0006] A support rod is fixedly mounted on the top surface of the base, a slot is provided on the side wall of the support rod, a telescopic rod is slidably sleeved inside the support rod, a bayonet is provided on the outer surface of the telescopic rod, a connecting block is fixedly mounted on the top end of the telescopic rod, and a mounting box is fixedly mounted on the front side of the connecting block;

The output end of the motor is fixedly connected to a rotating shaft. The bottom end of the rotating shaft is fixedly installed with a coupling device. The bottom end of the coupling device is fixedly connected to a rotor rod. The bottom end of the rotor rod is fixedly installed with a detection rotor. A protective frame is symmetrically installed on the outer surface of the coupling device. A detection cup is placed in the middle of the top surface of the base.

[0008] Preferably, the interior of the installation box includes:

[0009] A sleeve, fixedly connected to the bottom surface of the inner cavity of the installation box and located outside the rotating shaft;

[0010] an electromagnetic coil fixedly disposed inside the side wall of the sleeve;

[0011] a reciprocating thread, disposed on an outer surface of the rotating shaft;

[0012] The magnetic block is slidably sleeved on the outer surface of the rotating shaft and is located on the inner side of the sleeve.

[0013] Preferably, the sleeve includes:

[0014] An electromagnet is fixedly connected to the upper portion of the outer surface of the sleeve, and the magnetic properties of the magnetic slide are opposite to those of the electromagnet;

[0015] There are two chutes, which are symmetrically arranged on the outer surface of the sleeve and located under the electromagnet;

[0016] A magnetic slide plate is slidably sleeved on the outer surface of the sleeve and is located in the slide groove;

[0019] A hinge is fixedly hinged to the lower side of the installation box;

[0020] a deflector plate hinged on the hinge;

[0021] a snap ring, fixedly connected to the middle portion of the side of the deflection plate facing the detection cup;

[0023] Preferably, a hole for sliding the connecting rope is provided at the bottom of the installation box, and one end of the connecting rope away from the magnetic slide is fixedly connected to the deflection plate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By designing a sleeve, electromagnetic coil, electromagnet, deflection plate and retaining ring, when the viscosity of epoxy resin is tested, a motor is used to drive the rotating shaft to rotate, so that the reciprocating thread on the rotating shaft drives the magnetic block to reciprocate up and down inside the sleeve, prompting an electromagnetic effect to be generated between the electromagnetic coil and the magnetic block, causing the electromagnetic coil to generate current. Since the electromagnetic coil and the electromagnet are electrically connected, the electromagnet is magnetized, and the electromagnet is used to adsorb the magnetic slide, causing the magnetic slide to move upward. At this time, the magnetic slide will exert a pulling force on the connecting rope, and the connecting rope will pull the deflection plate to deflect, so that the retaining ring on the deflection plate will press against the test cup, thereby fixing the test cup, improving the stability of the test cup, and preventing the test cup from shaking during the test and affecting the test results.

[0026] 2. By designing the retaining ring and temperature-controlled heating plate, when the epoxy resin is tested, the temperature-controlled heating plate is adjusted to the preset temperature, so that the temperature-controlled heating plate will heat the test cup and heat the test cup to the preset temperature, so that the epoxy resin inside the test cup can be tested under the same temperature environment, avoiding the deviation of the test results caused by the influence of temperature during the test process, thereby improving the accuracy of epoxy resin testing.

[0034] See also Figure 1-Figure 4 The bottom surface of the inner cavity of the mounting box 7 is located on the outside of the rotating shaft 10 and is fixedly welded with a sleeve 71. An electromagnetic coil 72 is fixedly set inside the side wall of the sleeve 71. A reciprocating thread 101 is provided on the outer surface of the rotating shaft 10. The outer surface of the rotating shaft 10 is located on the inner side of the sleeve 71 and is slidably sleeved with a magnetic block 102 to ensure that when the rotating shaft 10 rotates, the reciprocating thread 101 is used to cause the magnetic block 102 to reciprocate up and down.

[0035] See also Figure 1-Figure 4 An electromagnet 73 is fixedly welded to the upper portion of the outer surface of the sleeve 71. Two sliding grooves 74 are symmetrically provided on the outer surface of the sleeve 71 at the lower side of the electromagnet 73. A magnetic slide 75 is slidably sleeved on the outer surface of the sleeve 71 at the sliding groove 74. The magnetism of the magnetic slide 75 is opposite to that of the electromagnet 73 after being magnetized. A connecting rope 76 is fixedly connected to the bottom surface of the magnetic slide 75, so that the magnetic slide 75 can exert tension on the connecting rope 76 when sliding up in the sliding groove 74.

[0036] See also Figure 1-Figure 4A hinge 77 is fixedly hinged on the lower side of the mounting box 7, and a deflection plate 78 is hinged on the hinge 77. A clamping ring 79 is fixedly welded on the middle part of the side of the deflection plate 78 facing the detection cup 15 to ensure that when the deflection plate 78 is deflected, the clamping ring is pressed against the detection cup 15, thereby fixing the detection cup 79.

[0037] See also Figure 1-Figure 4 The bottom of the mounting box 7 is provided with a hole for sliding the connecting rope 76 , and the end of the connecting rope 76 away from the magnetic slide 75 is fixedly connected to the deflection plate 78 to ensure that when the magnetic slide 75 slides up, the deflection plate 78 is deflected by pulling the connecting rope 76 .

[0038] Working principle: When the viscosity of epoxy resin needs to be tested, the epoxy resin is poured into the test cup 15, and then the telescopic rod 4 is adjusted to extend into the test cup 15, and the bayonet 5 is used to clamp the telescopic rod 4 in the card slot 3, and then the control panel 8 is used to control the motor 9 to drive the rotating shaft 10 to rotate. The rotating shaft 10 drives the rotor rod 12, the detection rotor 13 and the protective frame 14 to rotate through the coupling device 11, thereby causing the epoxy resin in the detection cup 15 to flow and be tested. At this time, due to the rotation of the rotating shaft 10, the reciprocating thread 101 on the rotating shaft 10 will drive the magnetic block 102 to reciprocate up and down inside the sleeve 71, causing an electromagnetic effect to be generated between the electromagnetic coil 72 and the magnetic block 102, causing the electromagnetic coil 72 to generate current. Since the electromagnetic coil 72 is electrically connected to the electromagnet 73, the electromagnet 73 is magnetized, which is beneficial to the flow of epoxy resin in the detection cup 15. The electromagnet 73 is used to adsorb the magnetic slide 75, so that the magnetic slide 75 moves upward. At this time, the magnetic slide 75 will apply tension to the connecting rope 76, and the connecting rope 76 will pull the deflection plate 78 to deflect, so that the clamping ring 79 on the deflection plate 78 will rest on the detection cup 15, thereby fixing the detection cup 15, improving the stability of the detection cup 15, and preventing the detection cup 15 from shaking during the detection process and affecting the detection results. At the same time, when the epoxy resin is tested, the temperature control heating plate 791 is adjusted to a preset temperature, so that the temperature control heating plate 791 will heat the detection cup 15, and heat the detection cup 15 to the preset temperature, so that the epoxy resin inside the detection cup 15 can be tested under the same temperature environment, avoiding the epoxy resin being affected by temperature during the detection process and causing deviations in the detection results, thereby improving the accuracy of epoxy resin detection.
