[0026] Based on the above scheme, the system is provided with a circulating moving mechanism 11, so that multiple loading components 12 can be moved to the working position in turn and cooperate with the manipulator 3 to realize automatic replacement of materials and dies 123. It is easy to use.

In addition, the manipulator 3 pours the material and places the die 123, which can avoid splashing of the material and deflection of the die 123, so as to further ensure the accuracy of the experimental data.

[0027] like Figure 2 As shown, in order to improve the loading efficiency, the circulating moving mechanism 11 includes a mounting frame 111, two conveyor belts 112 and two lifting assemblies 113; the conveyor belt 112 extends along the first direction X, and the two conveyor belts 112 are arranged on the mounting frame 111 at intervals along the second direction Y; the two lifting assemblies 113 are respectively located on both sides of the conveyor belt 112 in the first direction X; a plurality of material carrying assemblies 12 are respectively arranged on the two conveyor belts 112 and the two lifting assemblies 113, the conveyor belt 112 is used to drive the material carrying assemblies 12 to move along the first direction X, the lifting assemblies 113 are used to drive the material carrying assemblies 12 to move along the second direction Y, and the working position is arranged on one of the lifting assemblies 113;

At this time, there is a vacant position for the loading assembly 12 on the conveyor belt 112 located above, and the conveyor belt 112 located below moves the fully loaded loading assembly 12 to the conveyor belt 112 located above through another lifting assembly 113, thereby realizing the function of moving the loading assembly 12 to the working position in turn, and through the cooperation of the lifting assembly 113 and the conveyor belt 112, the occupation of the XZ plane by the circulating moving mechanism 11 is reduced, thereby improving the space utilization of the entire system.

[0029] like Figure 2 As shown, for ease of use, the lifting assembly 113 includes a driving cylinder 1131, a track 1132 and a pallet 1133. The track 1132 extends along the second direction Y, and the pallet 1133 is slidably connected to the track 1132. The driving cylinder 1131 is used to control the sliding of the pallet 1133 along the track 1132. The pallet 1133 is used to carry the material assembly 12, and the pallet 1133 can be flush with one of the conveyor belts 112 to be flush with the other conveyor belt 112. The material loading assembly 12 is supported by the pallet 1133, and then the driving cylinder 1131 drives the pallet 1133 to move in the second direction Y.

[0030] like Figure 2 As shown, for ease of use, the conveyor belt 112 includes a driving motor 1121, an active roller, a driven roller 1122 and a belt body 1123. The driving motor 1121 is installed on the mounting frame 111. The active roller and the driven roller 1122 are arranged on the mounting frame 111 at intervals along the first direction X, and are both rotatably connected to the mounting frame 111. The output end of the driving motor 1121 is transmission-connected to the active roller, and the belt body 1123 is transmission-wound around the active roller and the driven roller 1122. The mounting plate 121 is arranged on the belt body 1123 and can move along the first direction X as the belt body 1123 moves.

[0031] like Figure 2 As shown, in order to prevent the mounting plate 121 from sliding off the conveyor belt 112 , the conveyor belt 112 includes two baffles 1124 , which are respectively arranged on both sides of the belt body 1123 , and the top surfaces of the baffles 1124 protrude from the top surface of the belt body 1123 .

[0032] like Figure 2As shown, in order to move the carrier assembly 12 located on the lifting assembly 113 to the conveyor belt 112, the circulating moving mechanism 11 also includes two toggle assemblies 114, and the two toggle assemblies 114 are respectively installed on two transmission belts, one of the toggle assemblies 114 is used to move the carrier assembly 12 on one of the lifting assemblies 113 to one of the conveyor belts 112, and the other toggle assemblies 114 are used to move the carrier assembly 12 on the other lifting assembly 113 to the other conveyor belt 112.

[0033] like Figure 2 As shown, in order to improve the loading efficiency, the toggle assembly 114 includes a toggle cylinder 1141, a connecting rod 1142 and a toggle plate 1143. The toggle cylinder 1141 is installed on one side of the conveyor belt 112 in the third direction Z, and the toggle cylinder 1141 and the toggle plate 1143 are respectively located on both sides of the lifting assembly 113 in the first direction X. The connecting rod 1142 extends along the first direction X, and one end is connected to the toggle cylinder 1141, and the other end is connected to the toggle plate 1143. As the toggle cylinder 1141 drives the connecting rod 1142 to retract, the toggle plate 1143 can toggle the loading assembly 12 on the lifting assembly 113 onto the conveyor belt 112.

[0034] In some embodiments, an anti-slip plate is further provided on the side of the pallet 1133 away from the conveyor belt 112 in the first direction X, and the anti-slip plate is used to prevent the loading assembly 12 from detaching from the pallet 1133 when it moves from the conveyor belt 112 to the pallet 1133.

[0035] Furthermore, in order to adapt to the toggle assembly 114, a plurality of through grooves penetrating along the first direction X are provided on the anti-slip plate, and a protrusion adapted to the through groove is provided at the bottom of the toggle plate 1143. When the toggle plate 1143 moves toward the mounting plate 121, the protrusion passes through the through groove and abuts against the mounting plate 121. As the connecting rod 1142 continues to contract, the protrusion moves the mounting plate 121 onto the conveyor belt 112.

[0036] like Figure 3 As shown, in order to prevent the barrel 122 and the die 123 from falling off the mounting plate 121, the top surface of the mounting plate 121 has a first mounting groove 1211 and a second mounting groove 1212 spaced apart from each other, the barrel 122 can be detachably mounted in the first mounting groove 1211, and the die 123 can be detachably mounted in the second mounting groove 1212.

[0037] like Figure 4 and Figure 5As shown, for ease of use, it also includes a discharge device 4, the melt flow rate measuring instrument 2 also has a discharge port, and the discharge device 4 includes a blocking component 41 and a transportation component 42; the blocking component 41 includes a blocking piece 411, a first pushing cylinder 412 and a first bracket 413, the first bracket 413 is arranged on one side of the melt flow rate measuring instrument 2, the first pushing cylinder 412 is installed on the first bracket 413, the blocking piece 411 is connected to the output end of the first pushing cylinder 412, the first pushing cylinder 412 is used to drive the blocking piece 411 to move toward the discharge port to control the switch of the discharge port, and the transportation component 42 is arranged below the discharge port, and is used to move the outflowing melt and the die 123 out.

[0038] like Figure 6 As shown, for ease of use, the discharging device 4 also includes a cutting component 43, which includes a cutting knife 431, a second pushing cylinder 432 and a second bracket 433. The second bracket 433 is arranged on one side of the melt flow rate measuring instrument 2, and the second pushing cylinder 432 is installed on the second bracket 433. The cutting knife 431 is connected to the output end of the second pushing cylinder 432. The second pushing cylinder 432 is used to drive the cutting knife 431 to cut the melt flowing out of the discharging port, and the moving direction of the cutting knife 431 is the same as the moving direction of the transport component 42. Since the melt is a whole after flowing out of the discharging port, it is not convenient to move the melt. Therefore, the cutting device is set to cut the melt to ensure that the melt can be smoothly moved out.

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

[0040] 1. Before starting the experiment, first pour the materials into a plurality of barrels 122 and prepare a plurality of dies 123; then place the plurality of barrels 122 and the plurality of dies 123 on a plurality of mounting plates 121 respectively;

[0041] 2. When loading begins, the conveyor belt 112 located above transports the material loading component 12 to the lifting component 113 with a working position, and the manipulator 3 moves the die 123 and the barrel 122 on the working position to the feeding port in sequence, and pours the materials in the die 123 and the barrel 122 into the feeding port in sequence, and then puts the emptied barrel 122 back on the mounting plate 121, and the emptied material loading component 12 descends with the material loading component 12 and moves to the conveyor belt 112 located below. At this time, there is an empty position for the material loading component 12 on the conveyor belt 112 located above, and the conveyor belt 112 located below moves the fully loaded material loading component 12 to the conveyor belt 112 located above through another lifting component 113;

[0042] 3. After the material is loaded, the melt flow rate measuring instrument 2 performs the measurement, and the blocking member 411 blocks the discharge port at this time;

[0043] 4. After the measurement is completed, the blocking member 411 is moved away from the discharge port, and the melt flows out from the discharge port and is sheared by the cutting knife 431 and then removed by the transport assembly 42 together with the die 123 .

[0044] In summary, the embodiment of the utility model provides a melt flow rate measurement system, which, by setting a circulating moving mechanism 11, enables multiple loading components 12 to be moved to the working position in turn and cooperate with the manipulator 3 to realize automatic replacement of materials and dies 123, and is easy to use. It only needs to place multiple materials and multiple dies 123 on multiple mounting plates 121 before the experiment to conduct large-batch experiments, which can save time for replacing materials and dies 123. In addition, the pouring of materials and the placement of the dies 123 by the manipulator 3 can avoid splashing of materials and deflection of the dies 123, so as to further ensure the accuracy of the experimental data.

[0045] The above is only a preferred embodiment of the present invention. 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.
