[0021] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] like Figure 1 and Figure 2 As shown, a material injection device 1 of an embodiment of the utility model comprises: a mounting frame 11, a first lifting mechanism 12, a switching mechanism 13, a pressing mechanism 14 and a cleaning mechanism 15; the first lifting mechanism 12 is arranged on the mounting frame 11; the switching mechanism 13 comprises a rotating motor 131 and a mounting plate 132, the rotating motor 131 is mounted on the first lifting mechanism 12, the first lifting mechanism 12 is used to control the rotating motor 131 to move in a first direction X, the mounting plate 132 is arranged at the output end of the rotating motor 131, and the rotating motor 131 is used to control the mounting plate 132 to rotate in a plane where the second direction Y and the third direction Z intersect; the pressing mechanism 14 comprises a pressing rod 141 extending along the first direction X, the pressing rod 141 is arranged on the mounting plate 132; the cleaning mechanism 15 comprises a cleaning rod 151 extending along the first direction X and a cleaning cloth sleeved on the cleaning rod 151, the cleaning rod 151 is arranged on the mounting plate 132, and is spaced apart from the pressing rod 141, and the cleaning rod is used to sleeve the cleaning cloth.

[0025] Based on the above scheme, before measurement, the system first controls the rotation of the mounting plate 132 by the rotating motor 131, so that the pressing mechanism 14 can correspond to the injection port 21 of the melt flow rate instrument, and then controls the movement of the pressing rod 141 in the first direction X by the first lifting mechanism 12 to realize automatic pressing of the material and the melt; after measurement, the rotation of the mounting plate 132 is first controlled by the rotating motor 131, so that the cleaning mechanism 15 can correspond to the injection port 21 of the melt flow rate instrument, and then controls the movement of the cleaning mechanism in the first direction X by the first lifting mechanism 12 to realize automatic cleaning. The whole process does not require manual adjustment, which not only saves test time and improves detection efficiency, but also because the pressing rod 141 and the cleaning mechanism 15 are integrated into the same mounting plate 132. When in use, only the rotating motor 131 is needed to control the rotation of the mounting plate 132 to complete the switching, without occupying a large space, making the operation more convenient and efficient, and convenient for multiple measurements.

[0026] In some embodiments, in order to save materials, both the mounting plate 132 and the mounting frame 11 adopt a hollow structure.

[0027] like Figure 4 As shown, in order to save materials and facilitate installation, the mounting plate 132 includes a first extension portion 1321 and a second extension portion 1322, the first extension portion 1321 extends along the second direction Y, the second extension portion 1322 extends along the third direction Z, the pressing rod 141 is arranged on the first extension portion 1321, and the clearing rod 151 is arranged on the second extension portion 1322.

[0028] like Figure 2 As shown, in order to ensure the pressing effect, the pressing mechanism 14 further includes a pressing block 142, a side of the mounting plate 132 away from the pressing rod 141 has a mounting groove 1323, a mounting hole 1324 is opened at the bottom of the mounting groove 1323, the pressing block 142 is arranged in the mounting groove 1323, one end of the pressing rod 141 is passed through the mounting hole 1324, and abuts against the pressing block 142;

[0029] When pressing the material, the first lifting mechanism 12 controls the pressing rod 141 to be inserted into the injection port 21, and then continues to descend, so that the mounting plate 132 slides toward each other along the pressing rod 141, allowing the pressing block 142 to separate from the mounting groove 1323. At this time, the weight of the pressing block 142 acts on the pressing rod 141, thereby pressing the melt with a certain weight to ensure that the melt is in a compacted state.

[0030] like Figure 2As shown, in order to facilitate the pressing, the pressing mechanism 14 also includes a first clamping assembly 143, which is installed on the mounting plate 132, and the first clamping assembly 143 is used to fix the pressing rod 141 to the mounting hole 1324. When pressing, the first clamping assembly 143 loosens the pressing rod 141, so that the pressing rod 141 only bears the weight of the pressing block 142 to ensure the accuracy of the experimental data, and the detachable connection between the pressing rod 141 and the first clamping assembly 143 also facilitates the replacement of the pressing rod 141.

[0031] like Figure 4 and Figure 5 As shown, in order to prevent the pressing block 142 from falling off the pressing rod 141, the pressing rod 141 has a boss 1411 at one end facing the pressing block 142, and a groove 1421 matching the boss 1411 is formed on the side of the pressing block 142 facing the pressing rod 141. The boss 1411 can pass through the mounting hole 1324 and abut against the groove 1421.

[0032] like Figure 2 As shown, in order to facilitate the replacement of the cleaning mechanism 15, the cleaning mechanism 15 also includes a second clamping assembly 152, which is installed on the mounting plate 132 and is used to clamp one end of the cleaning rod 151 toward the mounting plate 132. When the cleaning mechanism 15 needs to be replaced, the second clamping assembly 152 releases the cleaning mechanism 15.

[0033] like Figure 4 As shown, in order to prevent the cleaning cloth from falling off the cleaning rod 151 during cleaning, the outer surface of the cleaning rod 151 also has a plurality of protrusions 1511 arranged at intervals.

[0034] like Figure 3 As shown, in order to ensure that the pressing rod 141 and the cleaning rod 151 can be accurately inserted into the injection port 21, the first lifting mechanism 12 includes a driving motor 121 and a first slide rail 122. The first slide rail 122 is arranged on the mounting frame 11 and extends along the first direction X. The driving motor 121 is arranged on the mounting frame 11, and the rotating motor 131 is arranged at the output end of the driving motor 121. The driving motor 121 is used to drive the rotating motor 131 to slide along the first slide rail 122.

[0035] like Figure 2As shown, for ease of use, it also includes a mounting seat 16, a second lifting mechanism 17 and a filling funnel 18. The mounting seat 16 has a second slide rail 161 extending along the second direction Y, the mounting frame 11 is slidably connected to the second slide rail 161, the second lifting mechanism 17 is arranged on the mounting frame 11, and is spaced apart from the first lifting mechanism 12 along the second direction Y; the filling funnel 18 is arranged on the second lifting mechanism 17, and the second lifting mechanism 17 is used to control the filling funnel to move in the first direction X; when filling, the filling funnel 18 can assist the filling to ensure that the material can flow into the filling port 21.

[0036] In some embodiments, an extension tube is further provided at the bottom of the injection funnel 18 . As the second lifting mechanism 17 moves, the extension tube can be inserted into the melt flow rate meter 2 to avoid wasting melt during injection.

[0037] In some embodiments, a baffle is further provided on the top of the injection funnel 18 to prevent splashing of material during injection.

[0038] like Figure 1 and Figure 2 As shown, a melt flow rate measurement system of an embodiment of the utility model comprises: a melt flow rate measuring instrument 2 and an injection device 1 as described above, wherein the melt flow rate measuring instrument 2 has an injection port 21, and as the rotating motor 131 drives the mounting plate 132 to rotate, the injection device 1 can switch between a pressing state and a clearing state, and when the injection device 1 is in the pressing state, the pressing rod 141 is arranged corresponding to the injection port 21, and when the injection device 1 is in the clearing state, the clearing rod 151 is arranged corresponding to the injection port 21.

[0039] The working process of the utility model is:

[0040] 1. To inject material into the melt flow rate measuring instrument 2, the mounting frame 11 first slides on the second slide rail 161 to make the injection funnel correspond to the injection port 21, and then the second lifting mechanism 17 controls the injection funnel 18 to move to the injection port 21, and finally injects material into the injection funnel 18;

[0041] 2. When the melt flow rate measuring instrument 2 is pressed, the second lifting mechanism 17 controls the injection funnel 18 to rise, and then the mounting frame 11 slides on the second slide rail 161 to make the pressing rod 141 correspond to the injection port 21, and finally the first lifting mechanism 12 controls the pressing rod 141 to be inserted into the injection port 21, and the pressing block 142 is separated from the pressing rod 141 to press the material;

[0042] 3. Start the melt flow rate measuring instrument 2 to conduct the experiment;

[0043] 4. After the experiment, the melt flow rate measuring instrument 2 is purged. First, the first lifting mechanism 12 controls the pressing rod 141 to rise, and then the rotating motor 131 drives the mounting plate 132 to rotate, so that the cleaning mechanism 15 corresponds to the injection port 21. Finally, the first lifting mechanism 12 controls the cleaning mechanism 15 to be inserted into the injection port 21 and reciprocate in the first direction X to clean the material.

[0044] In summary, the embodiment of the utility model provides a material injection device 1 and a melt flow rate measurement system. Before measurement, the rotation of the mounting plate 132 is first controlled by the rotating motor 131, so that the pressing mechanism 14 can correspond to the injection port 21 of the melt flow rate instrument, and then the first lifting mechanism 12 controls the movement of the pressing rod 141 in the first direction X to realize automatic pressing of the material and the melt; after measurement, the rotation of the mounting plate 132 is first controlled by the rotating motor 131, so that the cleaning mechanism 15 can correspond to the injection port 21 of the melt flow rate instrument, and then the first lifting mechanism 12 controls the movement of the cleaning mechanism 15 in the first direction X to realize automatic cleaning. The whole process does not require manual adjustment, which not only saves test time and improves detection efficiency, but also because the pressing rod 141 and the cleaning mechanism 15 are integrated into the same mounting plate 132. When in use, only the rotating motor 131 is needed to control the rotation of the mounting plate 132 to complete the switching, without occupying a large space, making the operation more convenient and efficient, and convenient for multiple measurements.

It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
