Description

Technical Field

[0001] The utility model relates to the technical field of Mooney viscometers, in particular to a Mooney viscometer detection and protection mechanism. Background Art

[0002] Mooney Viscometer is an instrument whose temperature control circuit (consisting of measurement and control module, platinum resistor and heater) automatically tracks the changes of power grid and ambient temperature and automatically corrects PID parameters to achieve fast and accurate temperature control. The data acquisition system and electromechanical linkage complete the automatic detection of torque signal during rubber testing and automatically display temperature value and set value in real time.

[0003] However, although the existing Mooney viscometer detection protection mechanism can make good use of the Mooney viscometer when in use, the upper mold and the lower mold are often in direct contact when the Mooney viscometer is used, and the shielding and sealing effect of the connection part of the upper mold and the lower mold is not high, so that when the product is placed in the Mooney viscometer for processing, it will cause overflow after softening, thereby reducing the accuracy of the product measurement data.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a Mooney viscosity meter detection protection mechanism is proposed. Utility Model Content

[0005] The utility model aims to provide a Mooney viscosity meter detection protection mechanism to solve the problem of low shielding and sealing effect on the connection part between the upper mold and the lower mold proposed in the above background technology.

[0008] Furthermore, the slide rail rods are symmetrically arranged on both sides of the lifting rod.

[0009] Furthermore, the nuts and bolts are provided in two groups, and the positions of the two groups of nuts and bolts are distributed symmetrically with respect to the central axis of the lower mold.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: Figure 1-Figure 3 As shown, a Mooney viscosity instrument detection protection mechanism includes an instrument body 1, an outer wall of the instrument body 1 is provided with a control panel 2, the outer wall of the instrument body 1 is slidably connected with a baffle 3, the inner wall of the instrument body 1 is fixedly connected with an electric push rod 4, one end of the electric push rod 4 is fixedly connected with a lifting rod 5 slidably connected to the inner wall of the instrument body 1, the outer wall of the lifting rod 5 is slidably connected with a slide rail rod 6 fixedly connected to the inner wall of the instrument body 1, the outer wall of the slide rail rod 6 is fixedly connected with an upper mold 7, the inner wall of the instrument body 1 is provided with a lower mold 8 located below the upper mold 7, the inner wall of the instrument body 1 is provided with a nut 9, the inner wall of the nut 9 is threadedly connected with a bolt 10, one end of the bolt 10 is rotatably connected with a protection block 11 slidably connected to the inner wall of the instrument body 1, and a sliding groove 12 is provided at the connection between the inner wall of the instrument body 1 and the protection block 11.

[0023] Furthermore, the slide rail rods 6 are symmetrically arranged on both sides of the lifting rod 5, which is beneficial to improve the stability of the lifting rod 5 in reciprocating sliding.

[0024] Furthermore, two groups of nuts 9 and bolts 10 are provided, and the positions of the two groups of nuts 9 and bolts 10 are distributed symmetrically with respect to the central axis of the lower mold 8. This is beneficial for driving the two groups of protective blocks 11 to slide relative to each other by providing two groups of nuts 9 and bolts 10 whose positions are distributed symmetrically with respect to the central axis of the lower mold 8.

[0025] Furthermore, the height of the protective block 11 is greater than the connection between the upper mold 7 and the lower mold 8. The protective block 11 is symmetrically arranged on both sides of the lower mold 8, and the outer wall contour of the protective block 11 is semicircular. The protective block 11 forms a sliding structure between the bolt 10 and the slide groove 12, which is beneficial to the rotation of the bolt 10, driving the protective block 11 to slide along the inner wall of the slide groove 12, thereby playing a role in effectively sealing and protecting the connection between the upper mold 7 and the lower mold 8.

[0026] Embodiment 2: Figure 1 , Figure 2 and Figure 4 As shown, a Mooney viscometer detection protection mechanism proposed by the utility model, compared with Example 1, as another implementation mode of the utility model, the inner wall of the instrument body 1 is rotatably connected with a worm 13, one end of the worm 13 is fixedly connected with a servo motor 14, the outer wall of the worm 13 is meshed with a worm wheel 15 rotatably connected to the inner wall of the instrument body 1, and the rotation center of the worm wheel 15 is fixedly connected with a cooling fan 16 located on one side of the lower mold 8. When working, by setting the cooling fan 16, it is beneficial to improve the anti-scalding effect of the operator when unloading the detected product when the product is detected and processed by the Mooney viscometer. When the upper mold 7 rises, the servo motor 14 and the cooling fan 16 can be turned on, and the rotation of the worm 13 drives the worm wheel 15 to rotate, and the rotation of the worm wheel 15 drives the cooling fan 16 to nod adjustment movement, which effectively cools the product on the surface of the lower mold 8, thereby improving the effect of improving the anti-scalding effect of the operator when unloading the product.

[0027] Furthermore, the rotation center of the worm gear 15 and the rotation center of the cooling fan 16 are on the same horizontal plane, which is beneficial to the effective adjustment of the use angle of the cooling fan 16.

[0028] Furthermore, the rotation center of the cooling fan 16 is driven by a motor. The cooling fan 16 forms a rotating structure with the instrument body 1 through the worm 13 and the worm wheel 15, which is beneficial to the rotation of the worm 13. Through the rotation of the worm wheel 15, the cooling fan 16 is driven to rotate along the inner wall of the instrument body 1, thereby effectively cooling the product on the surface of the lower mold 8, thereby achieving the effect of improving the operator's ability to prevent scalding when unloading the product.

[0029] Working principle: When using this Mooney viscometer to detect the protection mechanism, first, when the product is tested by the Mooney viscometer, in order to improve the sealing and protection effect of the connection between the upper mold 7 and the lower mold 8 when the product is heated, and to prevent the product from softening and overflowing, when the product is placed on the surface of the lower mold 8, the bolt 10 is turned through the limiting effect of the nut 9 to drive the protection block 11 to slide along the inner wall of the slide groove 12, and the electric push rod 4 is opened, and the lifting rod 5 is driven to perform a lifting movement through the limiting effect of the slide rail rod 6, so that the upper mold 7 is lowered, and the outer walls of the upper mold 7 and the lower mold 8 are fitted with the inner wall of the protection block 11, which plays a role in effectively sealing and protecting the connection between the upper mold 7 and the lower mold 8.

[0030] Finally, when the product is inspected and processed by the Mooney viscometer, in order to improve the anti-scalding effect of the operator when unloading the inspected product, the servo motor 14 and the cooling fan 16 can be turned on when the upper mold 7 rises, and the rotation of the worm 13 drives the worm gear 15 to rotate. The rotation of the worm gear 15 drives the cooling fan 16 to perform a nodding adjustment movement, which effectively cools the product on the surface of the lower mold 8, thereby improving the anti-scalding effect of the operator when unloading the product.
