Description

Technical Field

[0001] This utility model relates to the field of resin testing technology, and more specifically to a resin viscosity measuring device. Background Technology

[0002] Resin is a polymer compound that exists in a solid or semi-solid state at room temperature. When heated to a certain temperature, it softens and gradually liquefies as the temperature continues to rise.

[0003] Resin viscosity measurement is used to detect the resistance and viscosity of a fluid, thereby determining the quality and purity of the resin. The common method for this test is the viscometer method. The resin is poured into a measuring cup or a transparent cup, and then the viscometer is inserted into the resin. The viscosity value of the resin is measured by rotating or sliding the viscometer.

[0004] However, during resin testing, the viscosity of the resin changes with temperature under different indoor temperatures. In order to improve the accuracy of the test data, the resin in the cup is often heated to a certain temperature before testing. The temperature of the cup changes significantly during the process of removing it from the heating device and testing, which can lead to deviations in the test data and affect the accuracy of the resin test.

[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-5 As shown, a resin viscosity measuring device includes a measuring cup 5, and further includes:

[0031] Base frame 1, on which a constant temperature chassis 6 is installed;

[0032] Support frame 2 is mounted on base frame 1 and a detection unit 3 is mounted on support frame 2. The detection unit 3 includes a viscometer 31, which is matched with measuring cup 5.

[0033] Thermostatic frame 4 is snapped onto base frame 1. Thermostatic frame 4 has a solution chamber containing a solution. Thermostatic base plate 6 cooperates with thermostatic frame 4 to keep the solution in the solution chamber at a constant temperature.

[0034] A support column 42 is provided inside the solution chamber, and a clamping plate 41 is provided on the support column 42 to clamp the measuring cup 5.

[0035] Specifically, the measuring cup 5 is made of transparent glass to improve the thermal conductivity of the resin. The measuring cup 5 containing the resin is placed on the clamping plate 41 for clamping, and then the constant temperature plate 6 heats the solution to a certain temperature and maintains the temperature at a suitable temperature. The resin is then heated in the solution to a suitable test temperature. Then, the viscometer 31 is inserted into the measuring cup 5 to detect the viscosity, thereby obtaining and recording the viscosity test value, thus reducing the influence of temperature on the test value and improving the accuracy of the value.

[0036] As a further embodiment of this utility model, the constant temperature chassis 6 includes a heating wire 66, a bottom shell 67, and an adhesive plate 64 disposed on the bottom shell 67. The heating wire 66 is disposed between the bottom shell 67 and the adhesive plate 64, and the heating wire 66 is arranged in a vortex shape inside the bottom shell 67. The adhesive plate 64 is attached to the bottom surface of the constant temperature frame 4. The adhesive plate 64 is made of a thermally conductive material. Through the heating of the heating wire 66, heat is transferred to the constant temperature frame 4 through the adhesive plate 64 to heat the solution contained in the constant temperature frame 4. The vortex-shaped arrangement of the heating wire improves the heating efficiency of the adhesive plate 64.

[0037] As a further embodiment provided by this utility model, the constant temperature frame 4 is a transparent frame, and a sealing ring 43 is provided at the connection between the constant temperature frame 4 and the base frame 1. The sealing ring 43 is made of rubber, which improves the sealing effect between the constant temperature frame 4 and the base frame 1. In addition, the constant temperature frame 4 is located on the base frame 1 and can be removed for cleaning.

[0038] As a further embodiment of this utility model, a worm gear 422 and a worm 423 are rotatably mounted on the base frame 1, with the worm gear 422 meshing with the worm 423. A push rod 421, threadedly connected to the worm gear 422, is mounted on the support column 42. One end of the push rod 421 engages with the clamping plate 41. A knob is located on one side of the worm 423, and the knob is located on one side of the base frame 1 (e.g., ...). Figure 1 As shown, by rotating the worm gear 423 to control the rotation of the worm wheel 422, the top rod 421 slides on the support column 42 to adjust the height of the clamping plate 41, so as to accommodate measuring cups 5 of different sizes and detect the viscosity of resin at different volumes. The mouth of the measuring cup 5 is higher than the horizontal plane of the solution in the constant temperature frame 4.

[0039] As a further embodiment of this utility model, a screw 412 is rotatably provided on the clamping disk 41, and a clamping block 411 is provided on the screw 412 that slides on the clamping disk 41. Rotating the screw 412 controls the clamping block 411 to slide relative to or towards each other on the clamping disk 41, so as to clamp or remove the measuring cup 5.

[0040] As a further embodiment of this utility model, a controller 63 is snapped onto the base frame 1. The controller 63 has a display screen 62 and a control button 61. The controller 63 is electrically connected to the constant temperature chassis 6 via a connecting cable 65. The control button 61 can control the temperature on the constant temperature chassis 6, and at the same time display the temperature inside the constant temperature frame 4 through the display screen 62, so as to monitor the temperature inside the constant temperature frame 4 in real time.

[0041] As a further embodiment of this utility model, the support frame 2 includes a connecting plate 22, a base 24, and a support rod 23 disposed between the connecting plate 22 and the base 24. A sliding plate 21 is slidably disposed on the support rod 23. The sliding plate 21 supports the detection unit 3. The base 24 is fixed to the base frame 1 by bolts. The connecting plate 22 and the base 24 support the support rod 23 and guide the sliding plate 21 so that it can only slide in the vertical direction.

[0042] As a further embodiment of this utility model, the slide plate 21 is provided with a locking part 211, and a rotating rod 214 is rotatably provided inside the locking part 211. Both ends of the rotating rod 214 are provided with threaded parts 215, and the threaded parts 215 are provided with locking blocks 212 that fit with the support rod 23. A pulley 213 is provided at the axis of the rotating rod 214. The threads of the threaded parts 215 at both ends of the rotating rod 214 rotate in opposite directions. When the slide plate 21 needs to be fixed, the locking blocks 212 at both ends of the rotating rod 214 slide towards each other by rotating the pulley 213 until they contact the sliding groove 231 of the support rod 23, thereby fixing the slide plate 21 to the support rod 23.

[0043] As a further embodiment of this utility model, the detection unit 3 also includes a motor 32, a guide block 34, and a torque sensor 33 disposed on the guide block 34. The guide block 34 and the motor 32 are both fixed on the support frame 2. The motor 32 cooperates with the viscometer 31. The model of the motor 32 is MHMF042L1U4-1116. The motor 32 controls the viscometer 31 to rotate inside the measuring cup 5. Under the resistance of the resin, the change of torque is obtained through the torque sensor 33, and the magnitude of the resin viscosity is reflected by the torque.

[0044] As a further embodiment of this utility model, a heightening pad 11 is provided on the base frame 1. The heightening pad 11 is made of rubber, which improves the stability of the base frame 1 and also increases the sliding distance of the top rod 421.

[0045] Working principle: First, rotate the worm gear 423, which causes the worm wheel 422 to link with the push rod 421, making the push rod 421 slide along the support column 42 to adjust the height of the clamping plate 41. Then, place the measuring cup 5 containing resin on the clamping plate 41 and rotate the screw 412 to make the two clamping blocks 411 slide relative to each other to clamp and fix the measuring plate. Then, the solution in the constant temperature frame 4 is heated by the heating wire 66 to a certain temperature and kept constant. This heats the resin in the measuring cup 5 to a certain temperature. Then, the viscometer 31 is inserted into the measuring cup 5. Driven by the motor 32 and the torque sensor 33, the viscosity of the resin is detected, thereby reducing the influence of temperature on the detection value.

[0046] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
