[0026] A glue-applying device for processing plastic bottles, see [link / reference]. Figures 1 to 6The system includes a workbench 1 and an adhesive applicator 2 for applying pre-coated adhesive strips to plastic bottles. The adhesive applicator 2 includes a first fixed base 201, a first cylinder 202 mounted on the side of the first fixed base 201, and a lifting frame 203 that moves up and down on the side of the first fixed base 201 via the first cylinder 202. The lifting frame 203 is equipped with a first mounting frame 204 and a second mounting frame 205 that move at its bottom. A first silicone roller 206 and a second silicone roller 207 that roll simultaneously on the surface of the plastic bottle are respectively installed inside the first mounting frame 204 and the second mounting frame 205. The first silicone roller 206 and the second silicone roller 207 rotate within the first mounting frame 204 and the second mounting frame 205, respectively. In this embodiment, only the first cylinder 202 is needed to drive the lifting frame 203 along with the first silicone roller 207. 6. The first silicone roller 206 and the second silicone roller 207 move towards the plastic bottle simultaneously until they come into contact with the pre-coated adhesive strip on the plastic bottle and roll on the bottle surface. During this process, the first silicone roller 206 and the second silicone roller 207 will extend the strip of adhesive into a surface coating through rolling friction with the plastic bottle, thereby achieving the adhesive coating action on the plastic bottle. Through the cooperation of the above structures, this embodiment can adapt to the adhesive coating needs of plastic bottles of different specifications without the need to adjust or replace the parameters and structure of the equipment. This effectively solves the technical problem of the existing adhesive coating device having a fixed roller position, which requires multiple adjustments to equipment parameters or replacement of parts to adapt to different specifications of plastic bottles, resulting in reduced production efficiency.

[0027] The lifting frame 203 has a connecting shaft 208 inside, and a first connecting block 209 and a second connecting block 210 are respectively sleeved on both sides of the outer side of the connecting shaft 208. The first connecting block 209 and the second connecting block 210 simultaneously perform elastic movement outside the connecting shaft 208, and a first mounting bracket 204 and a second mounting bracket 205 are respectively installed on the bottom of the first connecting block 209 and the second connecting block 210. A first spring 211 and a second spring 212 are also respectively sleeved on both sides of the outer side of the connecting shaft 208. The two ends of the first spring 211 are welded to the side of the first connecting block 209 and the inner wall of one side of the lifting frame 203, respectively, and the two ends of the second spring 212 are... The first connecting block 209 is welded to the side of the second connecting block 210 and the inner wall of the other side of the lifting frame 203, respectively. A first bolt 213 is inserted into the top of the first connecting block 209 and is movable therein. One end of the first bolt 213 is threadedly connected to the first mounting bracket 204, and the first mounting bracket 204 is connected to the first connecting block 209 via the first bolt 213. A second bolt 214 is inserted into the top of the second connecting block 210 and is movable therein. One end of the second bolt 214 is threadedly connected to the second mounting bracket 205, and the second mounting bracket 205 is connected to the second connecting block 210 via the second bolt 214. A third spring is sleeved on the outside of the first bolt 213. 215, and the two ends of the first spring 211 abut against the bottom of the first connecting block 209 and the top of the first mounting bracket 204 respectively, and the first mounting bracket 204 drives the first silicone roller 206 to perform elastic movement at the bottom of the first connecting block 209 via the third spring 215; the second bolt 214 is externally fitted with a fourth spring 216, and the two ends of the fourth spring 216 abut against the bottom of the second connecting block 210 and the top of the second mounting bracket 205 respectively, and the second mounting bracket 205 drives the second silicone roller 207 to perform elastic movement at the bottom of the second connecting block 210 via the fourth spring 216; in this embodiment, when the first silicone roller 206 and the second silicone roller 207... When the glue roller 207 comes into contact with the glue strip pre-applied on the plastic bottle, the first silicone roller 206 and the second silicone roller 207 are continuously driven by the first cylinder 202 to move towards the plastic bottle until the plastic bottle is clamped between the first silicone roller 206 and the second silicone roller 207. During this process, the first silicone roller 206 and the second silicone roller 207 will simultaneously abut against the plastic bottle and drive the third spring 215 and the fourth spring 216 to undergo elastic deformation respectively. Then, the first silicone roller 206 and the second silicone roller 207 roll along the surface of the plastic bottle in opposite directions to generate rolling friction with the plastic bottle respectively.During the rolling of the first silicone roller 206 and the second silicone roller 207 in opposite directions, the third spring 215 and the fourth spring 216 maintain their elastic deformation state, and the first silicone roller 206 and the second silicone roller 207 simultaneously slide outside the connecting shaft 208, respectively driving the first spring 211 and the second spring 212 to undergo elastic deformation. The adhesive strip, under friction, extends into a planar coating, thus achieving the adhesive application to the plastic bottle. After adhesive application, the first cylinder 202 drives the first silicone roller 206 and the second silicone roller 207 to move in the opposite direction to the plastic bottle. At this time, the first silicone roller 206 and the second silicone roller 207 will roll along the surface of the plastic bottle in opposite directions. Simultaneously, the first spring 211 and the second spring 212 will gradually elastically reset, simultaneously driving the first silicone roller 206 and the second silicone roller 207 to elastically reset outside the connecting shaft 208. When the first silicone roller 206 and the second silicone roller 207 detach from the plastic bottle, the third spring 215 and the fourth spring 216 will synchronously drive the first silicone roller 206 and the second silicone roller 207 to elastically reset inside the first mounting bracket 204 and the second mounting bracket 205. The third spring 215 and the fourth spring 216 provide cushioning when the first silicone roller 206 and the second silicone roller 207 contact the plastic bottle, preventing excessive impact and thus affecting the surface quality of the plastic bottle. Furthermore, the first spring 211 and the second spring 212 not only allow the first silicone roller 206 and the second silicone roller 207 to adapt to applying glue to plastic bottles of different sizes, but also enable automatic reset after applying glue to the plastic bottle, facilitating the next round of glue application and effectively improving the practicality of this embodiment.

A second cylinder 405 is mounted on the front side of the first linear drive module 402. The second cylinder 405 is drivenly connected to the first lifting plate 403.

There are three fixtures 303 on the top of the tray 302, and the three fixtures 303 are located on the sides of the glue application mechanism 2, the loading mechanism 4, and the unloading mechanism 5, respectively. After the first pneumatic gripper 404 clamps the plastic bottle that has been pre-coated with glue strips, the first linear drive module 402 drives the first pneumatic gripper 404 and the plastic bottle to move laterally towards the fixture 303 on the side of the loading mechanism 4. When the plastic bottle is above the fixture 303, the second cylinder 405 drives the first pneumatic gripper 404 and the plastic bottle to move towards the fixture 303. The device moves vertically in three directions until the plastic bottle with pre-applied glue strips is placed in the fixture 303 on the side of the feeding mechanism 4. By cooperating with the above structures, the feeding action of the plastic bottle can be completed. Then, the rotary cylinder 301 drives the turntable 302, together with the plastic bottle with pre-applied glue strips, to rotate towards the glue coating mechanism 2 until the plastic bottle with pre-applied glue strips reaches below the first silicone roller 206 and the second silicone roller 207 of the glue coating mechanism 2. Then, the glue coating mechanism 2 can perform the glue coating action on the plastic bottle with pre-applied glue strips.After the gluing process is completed, the rotary cylinder 301 drives the turntable 302, along with the glued plastic bottle, to rotate towards the gluing mechanism 2 until the glued plastic bottle reaches below the second pneumatic gripper 504 of the unloading mechanism 5.

Then, the second linear drive module 502 drives the first pneumatic gripper 502 to rotate towards the glued plastic bottle. The second pneumatic gripper 504, along with the glued plastic bottle, moves towards the conveyor 506 until the glued plastic bottle is above the conveyor 506.
