[0035] Among them, Fig.10 As shown, the first cleaning cloth 111 and the second cleaning cloth 112 are prior art.

[0036] The feeding mechanism 2 includes a rotary table 21 and a plurality of feeding jigs 22 circumferentially mounted on the rotary table 21 . A barrel 23 is placed on the feeding jig 22 .

[0037] The funnel mechanism 61 includes a first lifting drive module 611 mounted on the main frame 60 and a funnel 612 mounted on the first lifting drive module 611. A material pipe 613 is mounted at one end of the funnel 612 for extending into the feeding port of the melt flow rate meter 4 when feeding the melt flow rate meter 4. The first lifting drive module 611 drives the funnel 612 to reciprocate longitudinally.

[0038] The adjustable weight mechanism 62 also includes a second lifting drive module 621 installed on the main frame 60 and an adjustable weight assembly 622 installed on the second lifting drive module 621, and a press rod 623 is installed on the adjustable weight assembly 622. The adjustable weight assembly 622 includes a bracket plate 6221, a placement hole 6222 is opened on the bracket plate 6221, a weight block 6223 is placed on the placement hole 6222, the press rod 623 is installed at the bottom of the weight block 6223, and a first clamping cylinder 6224 for clamping the press rod 623 is installed at the bottom of the bracket plate 6221. Among them, the second lifting drive module 621 drives the bracket plate 6221 to reciprocate longitudinally. When the melt flow rate meter 4 is working, the press rod 623 is used to extend into the feeding port of the melt flow rate meter 4 for use.

[0039] The cleaning rod mechanism 63 includes a third lifting drive module 631 installed on the main frame 60 and a cleaning rod 632 installed on the third lifting drive module 631. The third lifting drive module 631 drives the cleaning rod 632 to reciprocate longitudinally.

The fourth lifting drive module 641 drives the push block 643 to reciprocate longitudinally. When the melt flow rate meter 4 is cleaned, the push block 643 pushes the first cleaning cloth 111 to the outside of the placement box 642, the robot 3 grabs the first cleaning cloth 111 and places it on the top of the loading port of the melt flow rate meter 4, and the cleaning rod 632 extends the first cleaning cloth 111 into the inside of the loading port of the melt flow rate meter 4. Please note that the first cleaning cloth 111 is placed in the placement box 642 , and the first cleaning cloth 111 is different from the second cleaning cloth 112 described below in structure and placement position.

[0040] In addition, the cleaning rod 632 has a second function, that is, when the melt of the melt flow rate meter 4 needs a larger load, the cleaning rod 632 can be directly used to extend into the feeding port of the melt flow rate meter 4 when the melt flow rate meter 4 is working, so the top side of the cleaning rod 632 is also equipped with a clamping cylinder with the same structure as the first clamping cylinder 6224. At the same time, the automatic cleaning device 7 also has a second function, that is, the cleaning rod 632 directly moves to the top of the auxiliary clamping mechanism 72, the cleaning rod 632 is clamped by the auxiliary clamping mechanism 72, and then the cleaning rod 632 is cleaned by the second cleaning cloth 112.

[0041] The plugging assembly 41 includes a first push cylinder 411 and a plugging head 412 installed on the first push cylinder 411 and used to plug the melt inside the melt flow rate meter 4. A cutting assembly 42 is installed between the melt flow rate meter 4 and the discharge belt 5. The cutting assembly 42 includes a second push cylinder 421 and a cutting knife 422 installed on the second push cylinder 421. The first push cylinder 411 drives the plugging head 412 to reciprocate linearly, and the second push cylinder 421 drives the cutting knife 422 to reciprocate linearly. When the melt flow rate meter 4 completes its work, the plugging assembly 41 can realize automatic melt discharge by automatically pulling out the plugging head 412; when part of the melt flows downward to the discharge belt 5, it is easy to cool to form a column, and at this time the cutting knife 422 can cut the part of the melt to ensure smooth melt flow.

[0042] The automatic cleaning device 7 includes a rotating clamping mechanism 71 for clamping the pressing rod 623 and rotating the pressing rod 623 when cleaning the pressing rod 623, an auxiliary clamping mechanism 72 installed below the rotating clamping mechanism 71, and a second cleaning cloth conveying mechanism 73 installed below the auxiliary clamping mechanism 72.

[0043] The rotary clamping mechanism 71 includes a second transverse driving module 711 , a fifth lifting driving module 712 mounted on the second transverse driving module 711 , a rotary cylinder 713 mounted on the fifth lifting driving module 712 , and a second clamping cylinder 714 mounted on the rotary cylinder 713 .

[0044] The auxiliary clamping mechanism 72 includes mutually symmetrical abutting cylinders 721. One end of each abutting cylinder 721 has two columns 722. The top and bottom of each abutting column are equipped with rolling bearings. The auxiliary clamping mechanism 72 contacts the pressing rod 623 through the rolling bearings.

[0045] The second cleaning cloth conveying mechanism 73 includes a loading roller 731 for loading the second cleaning cloth 112, a first shaping block 732 installed on one side of the loading roller 731 and used for first shaping the second cleaning cloth 112, a second shaping block 733 installed on one side of the first shaping block 732 and used for second shaping the second cleaning cloth 112, and a receiving roller 735 installed below the loading roller 731. The second shaping block 733 is installed below the auxiliary clamping mechanism 72. A pressing assembly 734 is installed in the middle of the second shaping block 733 for pressing the second cleaning cloth 112 when the pressing rod 623 is cleaned. The function of the first shaping block 732 is to shape the second cleaning cloth 112 for the first time to form a folded shape; the function of the second shaping block 733 is to shape the second cleaning cloth 112 for the second time to form a folded shape, so that when the pressing rod 623 rotates, the second cleaning cloth 112 contacts the bottom and side wall of the pressing rod 623, and effectively cleans the bottom and side wall of the pressing rod 623. Please note that the second cleaning cloth 112 circulates between the feeding roller 731, the first shaping block 732, the second shaping block 733 and the unloading roller, and the second cleaning cloth 112 is different from the first cleaning cloth 111 in structure and placement.

[0046] The pressing assembly 734 includes a "冂"-shaped pressing block 7341 and a lifting cylinder 7342 installed at the bottom of the "冂"-shaped pressing block 7341. When cleaning the pressure rod 623, the second cleaning cloth 112 is pressed tightly. At this time, the second cleaning cloth 112 can still move forward, but its movement speed slows down. At the same time, its two ends are not easily deformed or pulled, which can increase the friction between the second cleaning cloth 112 and the pressure rod 623, ensuring that the second cleaning cloth 112 will not curl up due to the rotation of the pressure rod 623. At the same time, the second cleaning cloth 112 cleans the pressure rod 623 cleanly, and effectively saves the usage area of the second cleaning cloth 112.

[0047] An automatic melt flow rate instrument according to this embodiment, its automatic operation principle is as follows:

[0048] S1: The first lateral driving module 6 drives the hopper mechanism 61 to move, so that the material pipe 613 extends into the feeding port of the melt flow rate instrument 4. The manipulator 3 first grabs the cartridge 23 on the feeding jig 22 and pours it into the hopper 612, and then grabs the die and pours it into the hopper 612.

[0049] S2: The first lateral driving module 6 drives the hopper mechanism 61 and the adjustable load mechanism 62 to move, so that the pressure rod 623 extends into the feeding port of the melt flow rate instrument 4, and the melt flow rate instrument 4 starts to work. At this time, the adjustable load assembly 622 provides two load working modes: First, the first clamping cylinder 6224 releases and the second lifting driving module 621 drives the bracket plate 6221 to rise, and at this time only the pressure rod 623 bears the load; Second, the first clamping cylinder 6224 releases and the second lifting driving module 621 drives the bracket plate 6221 to descend, and at this time the weight block 6223 presses on the top of the pressure rod 623, and the pressure rod 623 abuts against the melt, and at this time the weight block 6223 and the pressure rod 623 bear the load simultaneously. In addition, the cleaning rod 632 can be used as a third load working mode.

[0050] S3: After the melt flow rate instrument 4 finishes working, the first pushing cylinder 411 drives the plug 412 to be pulled out, and the melt flow rate instrument 4 discharges the melt to the discharge belt 5. The second pushing cylinder 421 drives the cutting knife 422 to cut the cooled melt.

[0051] S4: The fourth lifting driving module 641 drives the push block 643 to rise, so that the first cleaning cloth 111 is pushed out of the placement box 642. The manipulator 3 takes out the first cleaning cloth 111 and places it on the top of the feeding port of the melt flow rate instrument 4. The first lateral driving module 6 drives the hopper mechanism 61, the adjustable load mechanism 62 and the cleaning rod 632 to move, so that the cleaning rod 632 extends the first cleaning cloth 111 into the feeding port of the melt flow rate instrument 4, and the cleaning step in S3 above is repeated several times.

[0052] S5: The first lateral driving module 6 drives the hopper mechanism 61 and the adjustable load-bearing mechanism 62 to move, so that the pressure rod 623 is located above the auxiliary clamping mechanism 72. The first clamping cylinder 6224 releases, and the auxiliary clamping mechanism 72 clamps the pressure rod 623. Then, the rotary clamping mechanism 71 moves above the pressure rod 623 and clamps the top of the pressure rod 623.

[0053] S6: The second cleaning cloth 112 passes through the first shaping block 732 and the second shaping block 733 in sequence. The second cleaning cloth 112 is pressed by the "冂"-shaped pressing block 7341 at the second shaping block 733, so that the second cleaning cloth 112 is shaped tighter, and the two ends of the second cleaning cloth 112 will not wrap around the pressure rod 623 and curl up due to the rotation of the pressure rod 623. At this time, the pressure rod 623 rotates, and the pressure rod 623 performs friction cleaning on the two inner end faces where the second cleaning cloth 112 is folded. In addition, the above automatic cleaning device 7 can also be used to clean the cleaning rod 632.

[0054] S7: The rotary clamping mechanism 71 is removed, the first lateral driving module 6 drives the adjustable load-bearing mechanism 62 to move over, and the first clamping cylinder 6224 clamps the pressure rod 623. Finally, the above-mentioned fully automatic melt flow rate instrument is reset to test the next melt material.

[0055] The fully automatic melt flow rate instrument of this embodiment realizes the full automation test of the melt flow rate instrument 4, greatly improves the test efficiency, has a low labor intensity for operators, and can realize a large number of tests.

[0056] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
