Description

Technical Field

[0001] This application relates to the field of viscosity testing devices, and more particularly to a polymer viscosity testing device. Background Technology

[0002] The published patent CN215812254U discloses a rapidly cleanable polymer viscosity testing device, belonging to the technical field of viscosity testing devices. Specifically, it is a rapidly cleanable polymer viscosity testing device, comprising a base plate and a bottom rotating column. A fixing ring is fixedly installed on the top of the base plate, a fixing spring is fixedly installed on the inner side of the fixing ring, and a clamping block is fixedly connected to the inner side of the fixing spring. A connecting block is fixedly installed on the top of the bottom rotating column. This rapidly cleanable polymer viscosity testing device, by creating a connecting cavity and a slot inside the top rotating column, and simultaneously installing a clip, spring, and clip block inside the connecting block, fixes the pressing block and the clip block together. This facilitates the fixation of the top and bottom rotating columns through the slot and the clip block, and also allows for quick separation of the clip block and slot through the pressing block, facilitating the cleaning of the bottom rotating column.

[0003] When the above device is implemented, the viscosity of the liquid in the beaker is tested by rotating the bottom rotating column. However, an existing polymer viscosity testing device cannot clean the liquid on the surface of the bottom rotating column after the test, causing the liquid to drip onto the surface of the base plate. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a polymer viscosity testing device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a polymer viscosity testing device, comprising a base, a clamping structure inside the base, a height adjustment structure on one side of the base, a movable frame slidably connected inside the height adjustment structure, a controller fixedly connected to one side of the movable frame, a detection structure fixedly connected to the bottom of the controller, a cleaning structure on the top of the movable frame, the cleaning structure comprising an air pump, the air pump being fixedly connected to the movable frame, a delivery pipe fixedly connected to the output end of the air pump, and a nozzle fixedly connected to the surface of the delivery pipe.

[0006] In a preferred embodiment, the clamping structure includes a motor, which is fixedly connected to a base. A threaded rod is fixedly connected to the output end of the motor, and a threaded rod is fixedly connected to one side of the threaded rod. Both the threaded rod and the threaded rod are rotatably connected to the base. The thread directions of the threaded rods are opposite. Clamping plates are threadedly connected to the surfaces of both the threaded rod and the threaded rod. The clamping plates are slidably connected to the base. A limit rod is slidably connected inside the clamping plates, and the limit rod is fixedly connected to the base.

[0007] By adopting the above technical solution, the output end of motor one drives threaded rod one and threaded rod two to rotate, and the rotation of threaded rod one and threaded rod two drives the clamping plate to move on the surface of the base to clamp and fix the beaker. The limiting rod limits the clamping plate, which can better clamp and fix the beaker.

[0008] In a preferred embodiment, a protective pad, which is made of rubber, is fixedly connected to the surface of the clamping plate.

[0009] By adopting the above technical solution, a protective pad is fixedly connected to the surface of the clamping plate, and the protective pad makes the clamping plate fit against the surface of the beaker, which can better clamp the beaker.

[0010] In a preferred embodiment, the height adjustment structure includes a fixed frame, which is fixedly connected to the base. A second motor is fixedly connected inside the fixed frame, and a threaded rod is fixedly connected to the output end of the second motor. The threaded rod is threadedly connected to the movable frame, and the movable frame is slidably connected to the fixed frame.

[0011] By adopting the above technical solution, the motor 2 is fixed by the fixed frame, and the output end of the motor 2 rotates to drive the threaded rod 3 to rotate. The rotation of the threaded rod 3 then causes the movable frame to move inside the fixed frame, which can better enable the movable frame to move inside the fixed frame.

[0012] In a preferred embodiment, the detection structure includes a motor three, which is fixedly connected to a controller. A rotating rod is fixedly connected to the output end of the motor three. A detection rod is slidably connected inside the rotating rod. A spring is fixedly connected inside the detection rod. A positioning rod is fixedly connected to one side of the spring. The positioning rod is slidably connected to the detection rod.

[0013] By adopting the above technical solution, the detection rod is inserted into the interior of the rotating rod to connect the rotating rod and the detection rod. Then, the positioning rod is supported by a spring and inserted into the interior of the rotating rod to position the detection rod. Finally, the output end of the motor drives the rotating rod and the detection rod to rotate, which can better enable the detection rod to rotate.

[0014] In a preferred embodiment, a heating plate is fixedly connected to the surface of the base, and the heating plate is electrically connected to the controller.

[0015] By adopting the above technical solution, a heating plate is fixedly connected to the surface of the base, and the heating plate heats and keeps the liquid in the beaker warm. The controller controls the switch of the heating plate, which can better heat and keep the liquid in the beaker warm.

[0016] In a preferred embodiment, the surface of the base is provided with a sliding groove, which is adapted to the clamping plate.

[0017] By adopting the above technical solution, a groove is provided on the surface of the base, and the clamping plate is limited by the groove, which can better enable the clamping plate to move on the surface of the base.

[0018] The beneficial effects of this application are:

[0019] 1. This polymer viscosity testing device, by setting up an air pump, a delivery pipe and a nozzle, draws outside air into the delivery pipe through the air pump, then delivers the air through the delivery pipe, and finally discharges the air through the nozzle on the surface of the delivery pipe, cleaning the residual liquid on the surface of the test rod. This avoids the problem of existing polymer viscosity testing devices being unable to clean the liquid on the surface of the bottom rotating column after the test, resulting in liquid dripping onto the base plate surface, thus improving practicality.

[0020] 2. This polymer viscosity testing device, by setting up a clamping plate, threaded rod one, threaded rod two, motor one, and limiting rod, uses the output end of motor one to rotate, driving threaded rod one and threaded rod two to rotate. The rotation of threaded rod one and threaded rod two then moves the clamping plate on the surface of the base to clamp and fix the beaker. The limiting rod then limits the clamping plate. This avoids the problem of waste of manpower and resources caused by the manual pulling of the pull plate required by existing polymer viscosity testing devices when clamping the beaker, thus improving practicality.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] Reference Figures 1-2 A polymer viscosity testing device includes a base 1, with a clamping structure 2 inside the base 1. The clamping structure 2 includes a motor 24, which is fixedly connected to the base 1. A threaded rod 23 is fixedly connected to the output end of the motor 24. A threaded rod 22 is fixedly connected to one side of the threaded rod 23. Both the threaded rod 22 and the threaded rod 23 are rotatably connected to the base 1. The thread directions of the threaded rods 22 and 23 are opposite, and both the threaded rods 22 and 23 are threaded. A clamping plate 21 is connected and slidably connected to the base 1. A limiting rod 25 is slidably connected inside the clamping plate 21 and is fixedly connected to the base 1. The output end of the motor 24 rotates to drive the threaded rod 22 and the threaded rod 23 to rotate. The rotation of the threaded rod 22 and the threaded rod 23 then drives the clamping plate 21 to move on the surface of the base 1 to clamp and fix the beaker. The limiting rod 25 then limits the clamping plate 21, which can better clamp and fix the beaker.

[0028] Reference Figures 1-2 A protective pad made of rubber is fixedly connected to the surface of the clamping plate 21. The protective pad is fixedly connected to the surface of the clamping plate 21, and the protective pad makes the clamping plate 21 fit against the surface of the beaker, so that the beaker can be better clamped.

[0029] Reference Figures 1-3A height adjustment structure 3 is provided on one side of the base 1. A movable frame 6 is slidably connected inside the height adjustment structure 3. The height adjustment structure 3 includes a fixed frame 31, which is fixedly connected to the base 1. A second motor 32 is fixedly connected inside the fixed frame 31. A threaded rod 33 is fixedly connected to the output end of the second motor 32. The threaded rod 33 is threadedly connected to the movable frame 6, and the movable frame 6 is slidably connected to the fixed frame 31. The second motor 32 is fixed by the fixed frame 31, and the output end of the second motor 32 rotates to drive the threaded rod 33 to rotate. The rotation of the threaded rod 33 causes the movable frame 6 to move inside the fixed frame 31, which can better enable the movable frame 6 to move inside the fixed frame 31.

[0030] Reference Figure 4 A controller 7 is fixedly connected to one side of the movable frame 6. A detection structure 4 is fixedly connected to the bottom of the controller 7. The detection structure 4 includes a motor 41, which is fixedly connected to the controller 7. A rotating rod 42 is fixedly connected to the output end of the motor 41. A detection rod 45 is slidably connected inside the rotating rod 42. A spring 44 is fixedly connected inside the detection rod 45. A positioning rod 43 is fixedly connected to one side of the spring 44. The positioning rod 43 is slidably connected to the detection rod 45. By inserting the detection rod 45 into the rotating rod 42, the rotating rod 42 and the detection rod 45 are connected. The spring 44 supports the positioning rod 43. The positioning rod 43 is then inserted into the rotating rod 42 to position the detection rod 45. The output end of the motor 41 rotates, driving the rotating rod 42 and the detection rod 45 to rotate. This allows the detection rod 45 to rotate more effectively.

[0031] Reference Figure 3 The top of the mobile frame 6 is provided with a cleaning structure 5, which includes an air pump 51. The air pump 51 is fixedly connected to the mobile frame 6. The output end of the air pump 51 is fixedly connected to a delivery pipe 52, and a nozzle 53 is fixedly connected to the surface of the delivery pipe 52.

[0032] Reference Figure 1 A heating plate 8 is fixedly connected to the surface of the base 1, and the heating plate 8 is electrically connected to the controller 7. The heating plate 8 is fixedly connected to the surface of the base 1, and the heating plate 8 heats and keeps the liquid in the beaker warm. The controller 7 controls the switch of the heating plate 8, which can better heat and keep the liquid in the beaker warm.

[0033] Reference Figures 1-2 The surface of the base 1 is provided with a sliding groove, which is adapted to the clamping plate 21. By providing a sliding groove on the surface of the base 1 and limiting the clamping plate 21 by the sliding groove, the clamping plate 21 can be moved more easily on the surface of the base 1.

[0034] Working principle: The beaker is placed on the surface of the base 1. The output end of motor 1 24 rotates, driving threaded rod 1 22 and threaded rod 23 to rotate. The rotation of threaded rod 1 22 and threaded rod 23 then moves the clamping plate 21 on the surface of the base 1 to clamp and fix the beaker. The limiting rod 25 limits the clamping plate 21. The fixing frame 31 fixes motor 2 32. The output end of motor 2 32 rotates, driving threaded rod 33 to rotate. The rotation of threaded rod 33 causes the moving frame 6 to move inside the fixing frame 31, adjusting the height of the detection rod 45. The detection rod 45 is then immersed in the liquid to be tested. Inside the beaker, the detection rod 45 is inserted into the rotating rod 42 to connect the rotating rod 42 and the detection rod 45. The positioning rod 43 is supported by the spring 44 and then inserted into the rotating rod 42 to position the detection rod 45. The output end of the motor 31 rotates to drive the rotating rod 42 and the detection rod 45 to rotate. The output of the motor 2 32 rotates to disengage the detection rod 45 from the inside of the beaker. The air pump 51 draws outside air into the delivery pipe 52, which then delivers the air. Finally, the nozzle 53 on the surface of the delivery pipe 52 discharges the air, cleaning the residual liquid on the surface of the detection rod 45.
