[0033] The driving mechanism 3 also includes a second worm gear 313, a second bearing seat 314, a second slide groove 315, a threaded block 316, a positioning block 317, a second servo motor 318, a threaded shaft 319, a connecting rod 320, a slider 321 and a limiting shaft 322. The second worm gear 313 is meshed with the top of the worm 308 on one side of the second gear 306. One side of the second worm gear 313 is fixedly connected to the second bearing seat 314. One side of the second worm gear 313 is provided with a second slide groove 315. One side of the second slide groove 315 is movably connected to the threaded block 316. One side of the threaded block 316 is fixedly installed with a positioning block 317. The second servo motor 318 is fixedly installed inside the positioning block 317.

[0036] It is necessary to further explain that: when it is necessary to provide power for the second bracket 4 to quantitatively output the raw material, the first servo motor 304 is started to drive the first gear 305 to mesh with the second gear 306 and the third gear 307, thereby driving the worm 308 on one side of the second gear 306 and the third gear 307 to rotate. When the worm 308 rotates, the first worm wheel 310 and the second worm wheel 313 are driven to mesh with each other. When the first worm wheel 310 and the second worm wheel 313 rotate, the connecting rod 320 is connected to the threaded block 316. and the slider 321 can rotate freely between the connecting rod 320 and the center of the second worm gear 313; when it is necessary to adjust the distance between the connecting rod 320 and the center of the second worm gear 313, the second servo motor 318 is started to drive the threaded shaft 319 to rotate. At this time, driven by the threaded shaft 319, the threaded block 316 moves on one side of the second slide groove 315, further driving the connecting rod 320 and the slider 321 to move on one side of the limiting shaft 322. By controlling the distance between the connecting rod 320 and the center of the second worm gear 313, the distance that the connecting rod 320 is driven to reciprocate when the second worm gear 313 rotates can be adjusted.

[0037] like Figure 5 , Figure 6 and Figure 7As shown, the output mechanism 5 includes a first one-way valve 51, a second one-way valve 52, a piston 501, a hollow tube 502, a transfer bin 503, a feed bin 504, a liquid outlet pipe 505 and a liquid blocking valve 506. The piston 501 is movably connected to one side of the connecting rod 320. The piston 501 is movably installed inside the hollow tube 502. The hollow tube 502 is connected to the transfer bin 503. The feed bin 504 is fixedly installed on the top of the transfer bin 503. The first one-way valve 51 is arranged at the connection between the transfer bin 503 and the feed bin 504. The liquid blocking valve 506 is movably installed on one side of the transfer bin 503. The liquid outlet pipe 505 is arranged at the bottom of the transfer bin 503. The second one-way valve 52 is arranged at the connection between the liquid outlet pipe 505 and the transfer bin 503.

[0038] The first one-way valve 51 and the second one-way valve 52 each include a limit tube 507, a ball valve 508, a limit rod 509 and a spring 510. The limit tube 507 is fixedly installed at the bottom of the transfer bin 503. The top of the limit tube 507 is fixedly connected to the spring 510. The top of the spring 510 is fixedly connected to the limit rod 509. The bottom of the limit rod 509 is fixedly connected to the ball valve 508. The ball valve 508 is movably connected to the bottom of the limit tube 507.

[0039] The lower material bin 504 is fixedly mounted on one side of the second bracket 4 , and the liquid outlet pipe 505 is arranged directly above the liquid collecting bin 6 .

[0040] What needs to be further explained is that: when liquid raw materials need to be output, the connecting rod 320 is movably installed on one side of the piston 501, and the connecting rod 320 drives the piston 501 to perform reciprocating linear motion inside the hollow tube 502. When the piston 501 moves to the left side of the hollow tube 502, the pressure inside the transfer bin 503 decreases. At this time, the limit rod 509 inside the first one-way valve 51 is pressed down by the external air pressure, thereby drawing the liquid at the bottom of the lower bin 504 into the transfer bin 503. When the piston 501 moves to the right side of the hollow tube 502, the pressure inside the transfer bin 503 increases. At this time, the limit rod 509 inside the second one-way valve 52 is affected by the high-pressure liquid inside the transfer bin 503, and pushes the ball valve 508 out of the limit tube 507, thereby discharging the liquid inside the transfer bin 503, completing the complete process of quantitative output.

[0041] Working principle and use process of the utility model: during the use of the utility model, when a quantitative output device for glue production raw materials is used, first, when it is necessary to provide power for the second bracket 4 to quantitatively output the raw materials, the first servo motor 304 is started to drive the first gear 305 to mesh with the second gear 306 and the third gear 307 respectively, thereby driving the worm 308 on one side of the second gear 306 and the third gear 307 to rotate, and when the worm 308 rotates, the first worm wheel 310 and the second worm wheel 313 are driven to mesh with each other, and when the first worm wheel 310 and the second worm wheel 313 rotate, the connecting rod 320 can rotate freely between the threaded block 316 and the slider 321;

[0042] Next, when it is necessary to adjust the distance between the connecting rod 320 and the center of the second worm gear 313, the second servo motor 318 is started to drive the threaded shaft 319 to rotate. At this time, driven by the threaded shaft 319, the threaded block 316 moves on one side of the second slide groove 315, further driving the connecting rod 320 and the slider 321 to move on one side of the limiting shaft 322. By controlling the distance between the connecting rod 320 and the center of the second worm gear 313, the distance that the connecting rod 320 is driven to reciprocate when the second worm gear 313 rotates can be adjusted.

[0043] Finally, when liquid raw materials need to be output, the connecting rod 320 is movably installed on one side of the piston 501, and the connecting rod 320 drives the piston 501 to perform reciprocating linear motion inside the hollow tube 502. When the piston 501 moves to the left side of the hollow tube 502, the pressure inside the transfer bin 503 decreases. At this time, the limiting rod 509 inside the first one-way valve 51 is pressed down by the external air pressure, thereby drawing the liquid at the bottom of the lower bin 504 into the transfer bin 503. When the piston 501 moves to the right side of the hollow tube 502, the pressure inside the transfer bin 503 increases. At this time, the limiting rod 509 inside the second one-way valve 52 is affected by the high-pressure liquid inside the transfer bin 503, and pushes the ball valve 508 out of the limiting tube 507, thereby discharging the liquid inside the transfer bin 503, completing the complete process of quantitative output.

[0044] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
