[0032] The working principle of the present application is as follows: When the present application is used, the rubber product is placed on the conveying belt 5 and then conveyed to the upper end of the gluing table 6, then the first drive motor 304 is started to drive the gluing cylinder 10 to move downward, when the gluing cylinder 10 moves downward and encounters the rubber product, the ejector rod 119 will be subjected to an upward force, thereby causing the pressing pipe 106 to push the force rod 111 to drive the force rod 110 to move downward, thereby allowing the rubber ring 101 to move out of the cylinder body 100 and contact the rubber product, in this process, the rubber ring 101 will deform after contacting the rubber product under the pushing of the force rod 110, thereby causing the glue to flow out through the glue discharge hole 102 and drop onto the rubber product, thereby completing the gluing of the rubber product, and as the rubber ring 101 is extruded, it will cover the glue that has dropped on the upper end of the rubber product, thereby applying the glue, which can save glue and avoid waste. Since the rubber ring 101 is uniformly extruded, the glue will be uniformly discharged from the multiple glue discharge holes 102, thereby increasing the uniformity of the glue application, and the other ejector rods 119 that do not contact the rubber product will enter the butt joint hole 8, thereby covering the rubber product with multiple gluing cylinders 10, thereby gluing according to the shape of the rubber product to avoid waste, and when the gluing is completed, the gluing cylinder 10 moves upward, at which time the pressing pipe 106 will reset under the action of the reset spring outside the glue inlet pipe 107, thereby causing the rubber ring 101 to be retracted into the cylinder body 100; When the present application is started, the glue will enter the pressure pipe 114 through the connecting hose 109 and the delivery pipe 124, the glue entering the pressure pipe 114 will push the temperature piston 116 to extrude the pressure spring 117, thereby compressing the air in the pressure pipe 114, the air in the pressure pipe 114 will be heated after being compressed, when the pressure in the pressure pipe 114 reaches the pulling limit of the elastic spring 126, the plug 125 will contact the exhaust hole 118 to block it, thereby causing the high-pressure gas with temperature in the pressure pipe 114 to be discharged into the heating chamber 115, at which time the glue will stop flowing into the pressure pipe 114 (it is worth noting that the transportation of glue into the pressure pipe 114 is intermittent, and the transportation will stop when it reaches the time, and at this time the exhaust hole 118 is just opened, this operation is completed in the PLC controller and is precisely controlled by the PLC program), and when the pressure in the pressure pipe 114 is released, the pressure spring 117 will reset against the temperature piston 116, at which time a negative pressure will be generated below the temperature piston 116 in the pressure pipe 114, thereby causing the blocking head 123 to unblock the connecting channel to allow external air to enter the pressure pipe 114, thereby allowing normal temperature air to enter the pressure pipe 114; And the temperature of the piston 116 in the process of moving up will push the glue to move up, at this time the glue will push the blocking piston 17, and part of the air in the pressure pipe 114 will also enter the control pipe 13 through the trigger pipe 11 and the drainage pipe 12, then push the pressure piston 19 to pull the blocking piston 17 to move, so that the blocking piston 17 contacts the blocking of the guide pipe 14, so that the glue in the pressure pipe 114 can enter the chamber along the guide pipe 14 for temporary storage, and when the next ejector rod 119 is lifted, the glue in the chamber flows into the pressure pipe 106 through the glue inlet pipe 107, and then flows into the glue outlet ring 101, so as to reciprocate and cycle to use the glue as power to make the high-temperature gas in the pressure pipe 114 increase the temperature in the temperature rising chamber 115, heat the whole barrel 100 and the glue outlet ring 101, and avoid the glue solidification; After the elastic force of the pressure spring 117 is released, the air in the control pipe 13 will be discharged from the pressure relief hole 20, and the pressure piston 19 and the blocking piston 17 will be reset (specifically, there is a certain pressure between the pressure piston 19 and the control pipe 13 to push the pressure piston 19 and the blocking piston 17), thereby preparing for the next cycle. The rubber products coated with glue will be sent to the discharge plate 7 under the rotation of the rotating wheel 9, and then move to the designated position along the discharge plate 7 to complete the glue coating.

[0033] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
