The interior of the cylinder body 100 is also slidably connected to a pressure pipe 106. The upper end of the pressure pipe 106 is fixedly connected to a glue inlet pipe 107. The glue inlet pipe The outer sleeve of 107 is provided with a return spring, and the glue inlet pipe 107 and the pressure pipe 106 are communicated with each other, the upper end of the glue inlet pipe 107 is fixedly connected with a partition 108, and the partition 108 is located in the chamber.

The lower end of the pressure tube 114 is also provided with a connecting channel connected to the outside world.

Specifically, a groove is provided at the top end of the inner side of the pressure tube 106, and the top end of the pressure tube 16 is located in the groove. The pressure in the heating chamber 115 can be transferred to the pressure tube 106 through the pressure tube 16, thereby promoting the flow of glue.

[0052] The working principle of the present invention is:

[0053] When the present invention is used, the rubber product is placed on the conveyor belt 5 and then conveyed to the upper end of the gluing table 6, and then the first driving motor 304 is turned on to drive the gluing cylinder 10 to move downward. When the gluing cylinder 10 encounters the obstruction of the rubber product during its downward movement, the push rod 119 will be subjected to an upward force, so that the pressure tube 106 pushes 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 100 and contact the rubber product. In this process, the rubber ring 101 will be deformed after contacting the rubber product under the push of the force rod 110, thereby causing the glue to flow out through the glue discharge hole 102 and drip onto the surface of the rubber product, thereby completing the gluing of the rubber product, and as the rubber ring 101 is squeezed out, it will cover the rubber. The glue dripping from the upper end of the rubber product is used to apply the glue, which can save glue and avoid glue waste. Since the rubber ring 101 is evenly squeezed, the glue will be evenly discharged from the multiple glue discharge holes 102, thereby increasing the uniformity of glue application. In addition, the other ejector pins 119 that are not in contact with the rubber product will enter the docking hole 8. In this way, multiple glue coating cylinders 10 can be used to cover the rubber product, and then glue can be applied according to the shape of the rubber product to avoid waste. When the glue application is completed, the glue coating cylinder 10 moves upward. At this time, the pressure tube 106 will be reset under the action of the reset spring outside the glue inlet pipe 107, so that the rubber ring 101 is re-integrated into the cylinder body 100.

[0054] When the present invention is started, glue will enter the pressure tube 114 through the connecting hose 109 and the delivery pipe 124. The glue entering the pressure tube 114 will push the heating piston 116 to squeeze the pressure spring 117, thereby compressing the air in the pressure tube 114. The air in the pressure tube 114 will heat up after being compressed. When the pressure in the pressure tube 114 reaches the pulling limit of the elastic spring 126, the plug 125 will contact the blockage of the exhaust hole 118, thereby causing the high-pressure gas with temperature in the pressure tube 114 to be discharged into the heating chamber 115. At this time, the glue will stop flowing into the pressure tube 114. (It is worth noting that the transportation of glue into the pressure tube 114 is intermittent, and the transportation will stop when the time is reached, and this is exactly when the exhaust hole 118 is opened. This operation is completed in the PLC controller and is precisely controlled by the PLC program), and when the pressure in the pressure tube 114 is released, the pressure spring 117 will push the heating piston 116 to reset. At this time, negative pressure will be generated below the heating piston 116 in the pressure tube 114, so that the blocking head 123 will release the obstruction of the connecting channel, allowing the outside air to enter the pressure tube 114, and then the pressure tube 114 will enter the air at normal temperature;

[0055] When the heating piston 116 moves upward, it pushes the glue upward. At this time, the glue pushes the blocking piston 17, and part of the air in the pressure tube 114 enters the control tube 13 through the trigger tube 11 and the drainage tube 12, and then pushes the pressure piston 19 to pull the blocking piston 17 to move, so that the blocking piston 17 contacts the obstruction of the guide tube 14, allowing the glue in the pressure tube 114 to enter the chamber along the guide tube 14 for temporary storage. When the push rod 119 is pushed up next time, the glue in the chamber will flow back through the glue inlet pipe 107 into the pressure pipe 106, and then flow into the rubber outlet ring 101. In this reciprocating cycle, the glue can be used as a power to generate high-temperature gas in the pressure tube 114 to increase the temperature in the heating chamber 115, thereby heating the entire cylinder 100 and the rubber outlet ring 101 to prevent the glue from solidifying.

[0056] After the elastic force of the pressure spring 117 is released, the air in the control tube 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 tube 13 to push the pressure piston 19 and the blocking piston 17), thereby preparing for the next cycle.

[0057] The rubber product coated with glue will be fed into the discharge plate 7 under the rotation of the rotating wheel 9, and then move along the discharge plate 7 to the designated position to complete the gluing.

[0058] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
