Specific implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a rubber bonding glue extrusion device includes a bottom plate 1. A lifting mechanism is installed at the top end of the bottom plate 1, and a filling mechanism is installed on the lifting mechanism. The filling mechanism includes an extrusion component and a sleeve 12 slidably connected to the extrusion mechanism. An outlet component is installed on the sleeve 12; the outlet component includes an extrusion nozzle 15 integrally formed with the bottom end of the sleeve 12. A second input pipe 17 communicating with the inner cavity of the sleeve 12 is installed on the outer wall of the sleeve 12, and a first liquid inlet check valve is installed on the second input pipe 17; the outlet component further includes a connecting pipe 18 connected to an eccentric position of the top plate of the sleeve 12. The output end of the connecting pipe 18 is connected to the extrusion nozzle 15, the input end of the connecting pipe 18 is communicated with the inner cavity of the sleeve 12, the output end of the connecting pipe 18 is communicated with the inner cavity of the extrusion nozzle 15, a liquid outlet check valve is installed on the connecting pipe 18 and the extrusion nozzle 15, and a first input pipe 16 communicating with the inner cavity of the sleeve 12 is connected to another eccentric position of the top end of the sleeve 12, and a second liquid inlet check valve is installed on the first input pipe 16.

[0020] In this embodiment: First, when filling rubber glue, place the filling container below the filling mechanism. At this time, start the lifting mechanism, and the lifting mechanism runs downward. The downward-running lifting mechanism drives the entire filling mechanism to move downward until the extrusion nozzle 15 enters the container. At this time, start the extrusion component, and the piston rod 13 of the extrusion component and the piston plate at its bottom end move up and down in the sleeve 12;

[0021] When the piston rod 13 and the piston plate move downward, the rubber glue located in the sleeve 12 is extruded through the extrusion nozzle 15 under pressure. At this time, the area above the piston plate inside the sleeve 12 is in a negative pressure state. Therefore, under the negative pressure suction, the rubber glue enters above the piston plate through the first input pipe 16;

[0022] When the piston rod 13 and the piston plate move upward after moving to the lowest point, the upward moving piston plate squeezes upward at this time, and the rubber glue in the sleeve 12 is squeezed into the extrusion nozzle 15 through the connecting pipe 18 and discharged through the extrusion nozzle 15. During this process, the area below the piston plate in the sleeve 12 is in a negative pressure state. Therefore, under the negative pressure suction, the rubber glue enters below the piston plate through the second input pipe 17. Therefore, continuous extrusion and filling effects can be achieved during the reciprocating up and down movement of the piston plate, improving the extrusion and filling efficiency;

[0023] It should be noted that: the output end of the connecting pipe 18 is located above the liquid outlet one-way valve of the extrusion nozzle 15.

[0024] Please refer specifically to Figure 1 , the lifting mechanism includes two lower guide rods 2 symmetrically and fixedly connected to the top of the bottom plate 1. A lower return spring 3 is sleeved on the outer wall of the lower guide rod 2. A lower sliding plate 4 is slidably connected to the outer wall of the lower guide rod 2. A lower return spring 3 sleeved on the lower guide rod 2 is fixedly connected between the bottom end of the lower sliding plate 4 and the top end of the bottom plate 1. One end of the lower sliding plate 4 is fixedly installed with a connecting plate 5 in a "Z" shape. A lower cylinder 6 is installed at the top end of the bottom plate 1. The output end of the lower cylinder 6 is fixedly connected to the bottom end of the upper cross plate part of the connecting plate 5.

[0025] In this embodiment: when the filling mechanism moves downward as a whole, by starting the lower cylinder 6, the lower cylinder 6 can drive the lower sliding plate 4 to move downward along the outer wall of the lower guide rod 2 through the connecting plate 5. At this time, the lower return spring 3 is compressed, and the downward moving lower sliding plate 4 can drive the filling mechanism to move downward as a whole. On the contrary, when the lower cylinder 6 extends, the filling mechanism moves upward as a whole.

[0026] Please refer specifically to Figure 2 And Figure 3 , the extrusion mechanism includes an upper cylinder 7 fixedly connected to the center position of the top end of the lower sliding plate 4. The output end of the upper cylinder 7 is fixedly connected to an upper sliding plate 8. An upper guide rod 10 is slidably connected to the inner wall of the upper sliding plate 8. The bottom end of the upper guide rod 10 is fixedly connected with a protruding ear 9. An upper return spring 11 sleeved on the upper guide rod 10 is fixedly connected between the top of the protruding ear 9 and the bottom end of the upper sliding plate 8. The extrusion mechanism further includes a piston rod 13 fixedly connected to the bottom end of the upper cylinder 7. The bottom end of the piston rod 13 penetrates into the inner cavity of the sleeve 12, and the bottom end of the piston rod 13 is fixedly connected with a piston plate. The piston plate fits with the inner wall of the sleeve 12, and a first seal is arranged at the contact position between the piston plate and the sleeve 12. A through hole for the piston rod 13 to slide up and down is opened on the top plate of the sleeve 12. The diameter of the through hole is equal to the diameter of the piston rod 13, and a second seal is installed on the inner wall of the through hole.

[0027] In this embodiment: After the filling mechanism moves downward to a proper position, by starting the upper air cylinder 7, the upper air cylinder 7 runs downward, and the upper air cylinder 7 drives the upper sliding plate 8 to move downward along the upper guide rod 10. At this time, the upper return spring 11 is compressed, and the downward-moving upper sliding plate 8 can push a plurality of piston rods 13 downward. On the contrary, when the upper air cylinder 7 makes an extending movement, it can drive the plurality of piston rods 13 to move upward, realizing the up-and-down movement of the piston rods 13 and the piston plates at their bottom ends on the inner wall of the sleeve 12.

[0028] Please refer with emphasis to Figure 3 , one end of the protruding ear 9 is integrally formed with one end of the lower sliding plate 4, and the sleeve 12 is fixedly connected to the lower sliding plate 4 through the mounting member 14.

[0029] In this embodiment: The integral formation of the protruding ear 9 and the lower sliding plate 4 can fix the position of the upper guide rod 10;

[0030] The mounting member 14 can effectively fix the sleeve 12.
