Description

Technical Field

[0001] The present invention relates to the technical field of new material viscosity detection, in particular to a viscosity testing device for liquid products. Background Art

[0002] In the research and development and production of new materials in the textile industry, the viscosity of liquid products such as textile oils, textile auxiliaries, and fabric anti-wrinkle finishing agents is one of the key indicators for measuring their performance. Accurate viscosity measurement is of great significance for product formulation optimization, production process regulation, and quality control. However, existing viscosity testing devices (viscometers) still have some problems that need to be solved in practical applications.

[0003] During measurement operations, viscosity testing devices (viscometers) are extremely susceptible to external impact interference such as collisions and vibrations. Such unexpected external disturbances will directly cause distortion of measurement data. However, traditional devices generally lack an effective mechanism to accurately identify such interference, making it difficult to issue an alarm to staff in the first place. If external impact interference such as collisions and vibrations occurs, staff may be unable to detect the abnormality in time due to other matters, which will not only cause distortion of subsequent measurement data, but also have a chain reaction of adverse effects on subsequent experimental analysis, production process control and other links. Summary of the Invention

[0008] Furthermore, the shake monitoring on-off switch adopts a touch switch, and the button end of the shake monitoring on-off switch faces the upper side. When the shake monitoring on-off switch is in the non-pressed start state, the button end of the shake monitoring on-off switch protrudes from the installation slot; when the shake monitoring on-off switch is in the pressed start state, the shake monitoring on-off switch feedback signal is given to the microcontroller, and the microcontroller controls the flexible film pressure sensor to start.

[0010] Furthermore, a tightening socket connected to the sway monitoring cavity is provided on the bottom surface of the inner end of the pressure groove relative to the axial center of the sway monitoring cavity, and the diameter of the tightening socket is larger than the diameter of the sway monitoring ball; a matching opening penetrating through the bottom surface of the base is provided on the top surface relative to the tightening socket, and the diameter of the matching opening is consistent with the diameter of the tightening socket.

[0013] The present invention provides a viscosity testing device for liquid products, which has the following beneficial effects: The present invention constructs a linkage mechanism for removing obstructions before measurement and activating the monitoring function through the design of the initial installation position of the tightening weight column, so that when a viscosity test is required, the staff must first pull out the tightening weight column from the tightening socket and the matching opening. This operation not only eliminates the physical obstruction when the container is placed, but also simultaneously releases the initial limit state of the sway monitoring ball, so that the sway monitoring ball used to realize sway monitoring enters a movable state.

[0014] The present invention is based on the linkage structure of the workbench and the pressure groove. After the container loaded with liquid product is placed on the workbench, the workbench is driven to move downward along the pressure groove based on the weight of the container itself. During this process, the spring connector is compressed into the spring receiving groove, and the bottom end surface of the workbench accurately presses the shaking monitoring start and close switch, triggering the micro-motion signal to be transmitted to the microcontroller, and then automatically activating the flexible film pressure sensor, so that the entire shaking monitoring system enters the real-time monitoring state, realizing the automatic triggering and starting of the shaking monitoring function, and avoiding the risk of the monitoring function not being activated due to manual operation omissions.

[0015] When the present invention is subjected to external impacts such as collisions and vibrations during the measurement process, the impact force will be transmitted to the sway monitoring cavity through the workbench. At this time, the sway monitoring ball originally in the temporary limit groove will break away from the initial limit due to inertia, roll along the upward convex arc surface at the bottom of the sway monitoring cavity, and come into contact with the circumferentially arranged flexible film pressure sensor. After the pressure sensor captures the signal, it immediately triggers the flashing warning light through the microcontroller to flash at a high frequency, and uses a visual light signal to send an abnormal alarm to the staff, accurately identify unexpected external interference, and remind the staff to re-measure, avoid distortion of measurement data caused by accidental shaking, and improve the measurement accuracy of the device.

[0023] The working principle of this embodiment is as follows: When measuring the viscosity of new material liquid products such as textile oils, textile auxiliaries, and fabric anti-wrinkle finishing agents, the liquid product can be added to a container, and then the container is placed on the workbench 3. The locking bolt 102 is loosened along the threaded locking through hole 104, so that the height position of the viscometer 1 can be moved up and down by sliding and plugging the movable socket 103 with the vertical rod 201, so that the rotor of the viscometer 1 is immersed in the liquid. Then, the locking bolt 102 is tightened through the threaded locking through hole 104, so that the stud end of the locking bolt 102 is tightly attached to the outer peripheral surface of the vertical rod 201, so as to achieve the limit fixation of the current height position of the viscometer 1, and then the viscometer 1 is started to measure the viscosity of the liquid product.

Based on the extraction of the tightening weight column 4, the limit fixation of the sway monitoring ball 2015 is released; When the container with liquid product is placed on the workbench 3, under the weight pressure of the container and the liquid product, the workbench 3 moves downward along the pressing groove 208, so that it is completely pressed into the pressing groove 208. At this time, the spring connector 302 is completely compressed into the spring receiving groove 209, and the bottom end surface of the workbench 3 is pressed into contact with the button end of the sway monitoring start and close switch 2013.

When it is affected by external collisions and other factors, such as the workbench where the current viscosity testing device is placed is hit, and the staff fails to find it due to other things, then the impact force generated by the collision The sway monitoring ball 2015 located inside the sway monitoring chamber 2011 will be separated from the temporary limit groove 2016 under the influence of the impact force. At this time, the sway monitoring ball 2015 will roll along the upward protruding bottom arc surface in the sway monitoring chamber 2011, so that it rolls and contacts the flexible film pressure sensor 2014 installed around the inner circumference of the sway monitoring chamber 2011. The flexible film pressure sensor 2014 senses the pressure signal and gives the feedback signal to the microcontroller 2018. The microcontroller 2018 controls the flashing warning light 203 to start. By flashing the flashing warning light 203, the staff is clearly reminded so that the staff knows that the current device is affected by the shaking and needs to be re-measured, so as to avoid the accuracy of the measurement data being affected by the shaking factor.
