[0024] Reference Figure 1 As shown, it is a preferred embodiment provided by the utility model.

[0025] The feeding structure for accurately controlling the residual amount of liquid silicone provided by the utility model comprises two synchronous cylinders 100 arranged at intervals and a rubber barrel 200 filled with liquid silicone, the synchronous cylinder 100 has a piston rod 110 that moves up and down, and the two piston rods 110 are respectively connected to a movable plate 300; a pressing plate 320 for squeezing the liquid silicone is provided at the bottom of the movable plate 300, and the pressing plate 320 is embedded in the rubber barrel 200, and an electronic ruler for measuring the displacement of the piston rod 110 is provided on the synchronous cylinder 100, and the electronic ruler and the synchronous cylinder 100 are respectively electrically connected to a controller;

[0026] When the synchronous cylinder 100 drives the piston rod 110 to move downward, the movable plate 300 moves downward, and the pressing plate 320 squeezes the liquid silicone in the rubber barrel 200 from top to bottom, and the liquid silicone is squeezed outward through the discharge port.

[0027] The feeding structure for accurately controlling the residual amount of liquid silicone provided above can monitor the residual amount of liquid silicone in real time through the measurement data of the electronic ruler. When the measurement data does not change significantly within a certain period of time, the controller determines that the pressure plate 320 is pressed to the bottom of the rubber barrel 200, and the controller controls the synchronous cylinder 100 to stop the piston rod 110 from moving downward. In this way, the residual amount of liquid silicone can be accurately controlled to solve the problem of excessive residual amount of liquid silicone.

[0028] The bottom of the movable plate 300 is provided with a telescopic rod 310 of variable length, and the bottom of the telescopic rod 310 is provided with a pressing plate 320. In this way, it can be applied to more different scenes and various glue barrels 200, and the set scene and glue barrel 200 can be adapted by initially changing the length of the telescopic rod 310 and fixing the length of the telescopic rod 310.

[0029] Specifically, the rubber barrel 200 has an inner cavity with an opening at the top, the liquid silicone is placed in the inner cavity, and the pressing plate 320 and the telescopic rod 310 are embedded in the inner cavity through the opening at the top. In this way, the structural arrangement is more reasonable, and the force can be directly applied to the liquid silicone.

[0030] An elastic sealing ring is arranged around the periphery of the pressing plate 320, and the sealing ring is clamped between the pressing plate 320 and the side wall of the inner cavity, so as to prevent the liquid silicone from leaking through the peripheral gap during the pressing process.

[0031] The pressing plate 320 is provided with a discharge hole which passes through from top to bottom, and the discharge hole forms a discharge port on the upper surface of the pressing plate 320, and the discharge port is connected with a discharge pipe 400. In this way, the discharge port is arranged on the pressing plate 320, and the effect is best.

[0032] Specifically, the glue barrel 200 is arranged between the two synchronous cylinders 100. In this way, the space arrangement is most reasonable and easy to operate.

[0033] The piston rods 110 of the two synchronous cylinders 100 are respectively connected to the two sides of the movable plate 300. In this way, the force points are symmetrical on both sides, the effect is best, the overall structure is most stable, and the service life is longer.

[0034] The telescopic rod 310 and the pressing plate 320 are arranged coaxially up and down. In this way, the pressing plate 320 is guaranteed to be balanced when subjected to force.

[0035] Specifically, the electronic ruler includes a ruler body, in which a measuring rod 510 is provided, which is consistent with the moving direction of the piston rod 110. The measuring rod 510 is connected to the piston rod 110 through a connecting frame 600. One end of the connecting frame 600 is fixedly connected to the measuring rod 510, and the other end of the connecting frame 600 is fixedly connected to the piston rod 110.

[0036] During the up and down movement of the piston rod 110, the measuring rod 510 moves synchronously under the action of the connecting frame 600, and the electronic ruler measures the displacement of the piston rod 110 according to the length of the measuring rod 510. In this way, precise and accurate measurement is achieved.

[0037] The ruler body is fixedly arranged on the side of the synchronous cylinder 100. In this way, the arrangement of the measuring rod 510 is facilitated, so that the measuring rod 510 and the piston rod 110 are arranged in parallel.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
