Description

Technical Field

[0001] This utility model relates to the field of rheological property testing technology for mesona chinensis glue, specifically a constant temperature rotational viscometer for testing the rheological properties of mesona chinensis glue. Background Technology

[0002] Mesona chinensis gum possesses bioactivities such as antioxidant, immunomodulatory, and hypoglycemic effects. Currently, during the production and preparation of mesona chinensis gum, it is necessary to test its rheological properties. Natural polysaccharides in existing technologies have been extensively studied due to their diverse bioactivities. They are also used as thickeners and gelling agents in the food industry due to their water-holding and gelling properties. Among these, the rheological properties of polysaccharides are the basis for their application in functional health foods and pharmaceutical industries.

[0003] Currently, rotational viscometers are commonly used to test rheological properties. These meters can be used to determine the viscosity and flow behavior of polymer liquids, as most polymers are processed and molded under viscous flow conditions. Therefore, understanding the performance characteristics of viscous flow is crucial in polymer production processes.

[0004] However, as an acidic heteropolysaccharide, the rheological properties of mesona chinensis gum are quite sensitive to temperature, pH value and shear rate. Although traditional rotational rheometers can measure the viscoelasticity of materials, they have poor adaptability to the temperature of mesona chinensis gum gelation process. At the same time, different rotors are required when testing mesona chinensis gum with different viscosities. However, the disassembly and assembly process of the rotor and motor is currently inefficient, which can easily affect the overall testing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a constant temperature rotational viscometer for testing the rheological properties of mesona chinensis glue, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a constant-temperature rotational viscometer for testing the rheological properties of mesona chinensis glue, comprising a base, a heating seat installed on the upper front side of the base, a beaker placed inside the heating seat, a support rod inserted into the upper rear side of the base, a connecting seat sleeved on the outside of the support rod, an adjusting bolt threaded onto the side of the connecting seat, the inner side of the adjusting bolt inserted into the support rod, a guide rod opposite to the front side of the support rod, the guide rod being inserted into the connecting seat, an instrument body connected to the front end of the connecting seat, a control panel on the front side of the instrument body, and a [missing information - likely a device or component] mounted on the lower end of the instrument body. The instrument includes a motor, with a rotor connected to the motor's output end. A temperature controller is installed on the left side of the instrument body, and a temperature sensor is installed on the lower left side of the instrument body. It also includes a quick-connect assembly between the motor and the rotor. The quick-connect assembly includes a fixed housing, a retaining sleeve, a knob, a concave surface, external teeth, and an inner groove. The fixed housing is connected to the outside of the motor's output end. A retaining sleeve is located inside the fixed housing. A knob is installed at the lower end of the fixed housing. The upper end of the knob has a concave surface that abuts against the outer side of the retaining sleeve. External teeth are fixed to the outside of the knob. An inner groove is formed inside the lower end of the fixed housing, and the inner groove connects to the external teeth.

[0007] Preferably, the fixing shell, the retaining sleeve, and the knob are all hollow in the middle, and the fixing shell, the retaining sleeve, and the knob are all connected to the outer side of the upper end of the rotor.

[0008] Preferably, both sides of the lower end of the card sleeve are provided with smooth inclined surfaces, and there is a gap between the two sides of the lower end of the card sleeve.

[0009] Preferably, both the inner groove and the outer teeth are spirally arranged, and the inner groove and the outer teeth are threadedly connected.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model forms a temperature control system by setting a heating base, a temperature controller and a temperature sensor. This system can detect the material temperature in real time during rheological testing of grass jelly, ensuring that the material is in a constant temperature state and avoiding deviations in the tested rheological data due to excessively high or low material temperatures. This improves the accuracy of rheological test data for grass jelly.

[0012] 2. This utility model incorporates a quick-connect component. The rotation of the knob and the fixed housing allows the external teeth on the knob to engage with the internal groove thread on the lower end of the fixed housing, enabling stable upward or downward movement of the knob. This allows the retaining sleeve inside the fixed housing to quickly clamp and engage the inserted rotor when the knob moves upward, due to pressure from the concave surface inside the upper end of the knob. When the knob moves downward, the pressure from the concave surface on the retaining sleeve is released, and the retaining sleeve, combined with its own elasticity, automatically releases the clamping engagement, allowing for quick rotor disassembly. Therefore, different rotors can be easily replaced with different motors to adapt to rheological data acquisition at different shear rates. Attached Figure Description

Detailed Implementation

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1-2This utility model provides a constant temperature rotational viscometer for testing the rheological properties of mesona chinensis glue, including a base 1, a heating seat 2 installed on the upper front side of the base 1, a beaker 3 placed inside the heating seat 2, a support rod 4 inserted into the upper rear side of the base 1, a connecting seat 5 sleeved on the outside of the support rod 4, an adjusting bolt 6 threadedly connected to the side of the connecting seat 5, and the inner side of the adjusting bolt 6 inserted into the support rod 4, a guide rod 7 opposite to the front side of the support rod 4, and the guide rod 7 inserted into the inside of the connecting seat 5, an instrument body 8 connected to the front end of the connecting seat 5, a control panel 9 on the front side of the instrument body 8, a motor 10 installed at the lower end of the instrument body 8, a rotor 11 connected to the output end of the motor 10, a temperature controller 12 installed on the left side of the instrument body 8, a temperature sensor 13 installed on the lower left side of the instrument body 8, and a quick-connect assembly 14 located between the motor 10 and the rotor 11.

[0021] The support rod 4 has multiple round holes equidistantly spaced vertically on its left side. The support rod 4 is connected to the adjusting bolt 6 threaded on the side of the connecting seat 5 through these round holes, thereby enabling the flexible up-and-down adjustment of the instrument body 8.

[0022] Please see Figure 3-5 In this embodiment, the quick-connect assembly 14 includes a fixed housing 141, a retaining sleeve 142, a knob 143, an inner concave surface 144, an outer tooth 145, and an inner groove 146. The fixed housing 141 is mated to the outside of the output end of the motor 10. The retaining sleeve 142 is installed inside the fixed housing 141, and both sides of the lower end of the retaining sleeve 142 are set in a semi-arc plate shape. The retaining sleeve 142 is made of elastic plastic material. The knob 143 is installed at the lower end of the fixed housing 141. The upper end of the knob 143 is inside... The knob 143 has a concave surface 144 that abuts against the outer side of the sleeve 142. Thus, during the rotation of the knob 143, the sleeve 142 can be squeezed upwards by the concave surface 144 to achieve clamping and locking. The knob 143 has an external tooth 145 fixed on its outside. The lower end of the fixed shell 141 has an inner groove 146 that is connected to the external tooth 145. This ensures that the sleeve 142 is firmly clamped and docked, reducing the occurrence of loose docking.

[0023] The fixing shell 141, the clamping sleeve 142, and the knob 143 are all hollow in the middle, and they are all connected to the outer side of the upper end of the rotor 11. This ensures that the fixing shell 141, the clamping sleeve 142, and the knob 143 can be stably connected to the upper end of the rotor 11, thereby facilitating the installation of different rotors 11 and expanding the testing and application range.

[0024] The lower ends of the sleeve 142 are both smooth and inclined, and there is a gap between the lower ends of the sleeve 142. Thus, when the knob 143 moves upward, it can work with the concave surface 144 inside the upper end to press against each other, so that the lower ends of the sleeve 142 come closer together and achieve a firm clamping and docking action.

[0025] The inner groove 146 and the outer tooth 145 are both spirally arranged, and the inner groove 146 and the outer tooth 145 are threadedly connected to ensure that the inner groove 146 and the outer tooth 145 are threadedly connected, thereby achieving a stable self-locking fit and improving the firmness of the connection.

[0026] The working principle is as follows:

[0027] First, pour the herbal jelly to be tested into beaker 3. After pouring, rotate the adjusting bolt 6 on the side of the connecting seat 5 to move the adjusting bolt 6 outward in advance. This releases the locking between the adjusting bolt 6 and the round hole on the outside of the support rod 4. This allows the instrument body 8 to move downward in coordination with the connecting seat 5, the support rod 4, and the guide rod 7. This allows the rotor 11 to move into beaker 3. After the downward movement is completed, tighten the adjusting bolt 6 again to re-lock the connecting seat 5 and the support rod 4, keeping the instrument body 8 stable. At this time, the motor 10 at the bottom can be driven by the control panel 9 on the front of the instrument body 8. Driven by the motor 10, the rotor 11 connected to the output end of the motor 10 can rotate rapidly to detect the rheological and gel properties of the herbal jelly inside beaker 3. The detected characteristic data can be displayed on the control panel 9, allowing the staff to intuitively understand the herbal jelly test characteristic data.

[0028] Because the temperature of the mesona chinensis gel itself will have a certain impact on the test data during the rheological property test, when the rotor 11 moves downward, the temperature sensor 13 installed on the lower left side of the instrument body 8 can move into the beaker 3 to detect the temperature of the mesona chinensis gel in real time. However, when the temperature of the mesona chinensis gel decreases, the temperature sensor 13 will send a heating signal to the temperature controller 12, and the temperature controller 12 can control the heating seat 2 set at the upper front of the base 1 to heat the beaker 3, so that the mesona chinensis gel inside the beaker 3 can be restored to a constant temperature state, ensuring the accuracy of subsequent test data.

[0029] Secondly, due to the varying testing requirements of different herbal glues, the rotor 11 types used are inconsistent. To facilitate rapid assembly and disassembly of the rotor 11, a quick-connect assembly 14 is installed between the motor 10 and the rotor 11. When disassembling the rotor 11, the knob 143 at the lower end of the fixed housing 141 can be rotated. This allows the knob 143 to engage with the threaded groove 146 inside the lower end of the fixed housing 141 via the external teeth 145. As the knob 143 rotates downwards, the concave surface 144 at the upper end of the knob 143 releases the pressure on the retaining sleeve 142 inside the fixed housing 141. The retaining sleeve 142 then returns to its original position due to its elasticity. Thus, the retaining sleeve 142, which was originally clamping the upper end of the rotor 11, automatically returns to its original position, releasing the clamping effect and allowing the upper end of the rotor 11 to be quickly unlocked and removed from the fixed housing. Inside the housing 141, the rotor 11 is easily disassembled. When reconnecting, the upper end of the rotor 11 is first inserted into the housing 141, the sleeve 142, and the knob 143. When the upper end of the rotor 11 abuts against the bottom output end of the motor 10, the knob 143 can be rotated to allow the knob 143 to engage with the threaded connection between the outer teeth 145 and the inner groove 146, thus moving upward. As the knob 143 moves upward, the sleeve 142, which abuts against the concave surface 144 inside the upper end of the knob 143, is squeezed upward to clamp the inserted rotor 11, allowing the rotor 11 to complete the quick clamping and docking. At the same time, the threaded connection between the outer teeth 145 and the inner groove 146 ensures a firm clamping and docking state, reducing the problem of loose connection. In this way, different rotors 11 and motors 10 can be docked quickly and conveniently, and the acquisition of rheological data of the styrax can be adapted to different shear rates.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
