[0002] When producing and processing rubber products, it is necessary to use a glue filling machine to inject the glue into the canned bottle. When the existing glue filling machine quickly injects the glue into the canned bottle, as the glue liquid level inside the bottle body rises upward, the sprayed glue will splash in the canned bottle, so that the splashed glue will expand outward at the bottle mouth and drip on the surface of the bottle body, which will not only pollute the bottle body, but also require staff or cleaning equipment to clean the bottle body, resulting in an increase in production costs, etc., and there are major defects. For this reason, we propose a drip-proof device for the discharge port of a glue filling machine. Utility Model Content

[0027] Working principle: When injecting the rubber into the canned bottle, the injection pipe 1 is inserted into the canned bottle through the external connecting rod, and the rubber is injected into the suction pipe 11 through the injection conduit 13. The rubber can be injected into the canned bottle through the injection port 12 on the lower side of the outer periphery. When the liquid surface of the rubber inside the bottle moves upward to contact the lower end of the suction pipe 11, the rubber can be sucked out through the suction pipe 11 and the suction conduit 15, so as to avoid the rubber from overflowing.

[0028] When the volume of the rubber inside the bottle needs to be adjusted, the movable tube 21 can be rotated. Through the plug-in connection between the movable tube 21 and the extension tube 2 and the threaded connection between the extension tube 2 and the suction tube 11, the rotating movable tube 21 can drive the extension tube 2 to move up and down in the suction tube 11, thereby adjusting the contact depth between the lower end of the extension tube 2 and the rubber liquid surface.

[0030] Specifically, a first gear pump 14 is provided to cooperate with the injection pipe 13 to inject the rubber into the injection pipe 1, and a second gear pump 16 is provided to cooperate with the suction pipe 15 to suck the rubber inside the suction pipe 11 outwards;

[0031] A motor 22 is provided, and the movable tube 21 can be driven to rotate through the fixed connection between its output shaft and the movable tube 21. Through the plug-in connection between the limiting rail 26 and the limiting slot 25, the rotating movable tube 21 can drive the extension tube 2 to rotate with it, and then the rotating extension tube 2 can drive the extension tube 2 to move up and down through the threaded connection between the extension tube 2 and the suction tube 11.

[0032] As a further description of the above technical solution: a limit plate 3 is fixedly installed on the periphery of the injection tube 1, and a plurality of support plates 31 distributed in a circular array are slidably installed on the lower end of the limit plate 3. A plurality of movable blocks 32 corresponding to the positions of the support plates 31 are slidably installed on the periphery of the injection tube 1, and a diagonal support plate 35 is rotatably installed between the corresponding movable blocks 32 and the support plates 31. A limit slot 33 is provided on the periphery of the injection tube 1, and a limit slider 34 slidably connected to the limit slot 33 is fixedly installed on the inner end of the movable block 32. A driving disk 36 is rotatably installed on the upper end of the limit plate 3, and the upper end surface of the limit plate 3 is provided with a plurality of movable blocks 32 corresponding to the positions of the support plates 31. A guide slot 371 corresponding to the position of 31 is fixedly installed on the upper end of the support plate 31, and a sliding shaft 37 slidably connected to the guide slot 371 is fixedly installed, and a driving slot 372 slidably connected to each sliding shaft 37 is opened at the lower end of the driving disk 36, and the driving slot 372 is inclined. The outer periphery of the driving disk 36 and the inner wall of the limit disk 3 are respectively fixedly installed with a first positioning block 38 and a second positioning block 381 corresponding to each other in position, a spring 382 and an arc-shaped telescopic sleeve 383 inserted into each other are fixedly installed between the first positioning block 38 and the second positioning block 381, and the spring 382 is sleeved on the outer periphery of the arc-shaped telescopic sleeve 383.

[0033] Specifically, when the injection tube 1 is inserted into the canned bottle, the inclined support plate 35 contacts with the bottle mouth, thereby pressing the inclined support plate 35 inward, and through the sliding connection between the limiting slide groove 33 and the limiting slider 34 and between the slide shaft 37 and the guide slide groove 371, the inclined support plate 35 moving inward drives the movable block 32 to move downward and drives the support plate 31 to move inward, thereby making the support plate 31 contact with the inner wall of the bottle body, and adjusting the relative position of the injection tube 1 and the bottle body, so that the injection tube 1 is in the middle of the bottle body;

[0034] Among them, through the sliding connection between the sliding shaft 37 and the guide slide groove 371, the support plate 31 moving inward can drive the driving disk 36 to rotate and compress the spring 382 through the sliding connection between the sliding shaft 37 and the driving slide groove 372. Then, under the action of the spring 382 restoring the deformation, the driving disk 36 can be driven to rotate in the opposite direction, so that the support plate 31 can always fit with the inner wall of the canning bottle body, ensuring the relative position of the filling tube 1 and the bottle body is stable.
