For better understanding of the present invention, please refer to fig. 1, the pressure-sensitive adhesive tape bundling apparatus for plastic pipe ring comprises a side vertical plate 1, a three-axis moving mechanism 2, an adhesive tape carrying platform 3 and an adhesive tape rolling mechanism. The function of the tape carrier 3 is to carry the tape section 4 transferred from the tape supply device, which is located below the tape rolling mechanism, in particular below the longitudinally telescopic suction head of the tape rolling mechanism. The adhesive tape carrying platform 3 is formed by taking a strip-shaped body as a base body, a through hole 3a penetrating up and down is formed in the strip-shaped body, and the through hole 3a is connected with a vacuum adsorption pipeline to be used as a second adsorption port and used for adsorbing the adhesive tape section 4 on the upper surface of the adhesive tape carrying platform 3. Baffle plates 3b are respectively arranged on two sides of the strip-shaped body, the width between the baffle plates 3b is slightly larger than the width of the adhesive tape section 4 so as to ensure that the adhesive tape section 4 is parallel to the length direction of the strip-shaped body on the surface of the adhesive tape carrying platform 3, and a foundation is provided for aligning the head and the tail of the adhesive tape when the subsequent adhesive tape is rolled in a wide mode. As shown in fig. 2, the movement of the tape carrier 3 is performed by the three-axis moving mechanism 2, one axis of the three-axis moving mechanism 2 is vertical, the three-axis moving mechanism 2 and the tape rolling mechanism are fixed to the side vertical plate 1, the tape carrier 3 is adjusted in position relative to the tape rolling mechanism by the action of the three-axis moving mechanism 2, so that the tape segment 4 can be accurately moved from the tape carrier 4 to the tape rolling mechanism, and the tape carrier 3 can avoid the plastic pipe ring during the bundling operation by the action of the three-axis moving mechanism 2, so as to leave an action space for the tape rolling mechanism. The specific three-axis moving mechanism 2 comprises a horizontal first cylinder 2a, a horizontal second cylinder 2b and a longitudinal axis cylinder 2c which are sequentially connected and driven so as to enable the adhesive tape carrying platform to perform linear movement in the horizontal plane and in the longitudinal direction.
As shown in fig. 3 and 4, the tape rolling mechanism is connected to the side vertical plate 1, and the tape rolling mechanism includes a frame 5, a first longitudinal driving device 6, a second longitudinal driving device 7, a longitudinal telescopic adsorption head 8, a fixed side block 9, and a movable side block 10. The first longitudinal driving device 6 and the second longitudinal driving device 7 are both cylinders, the first longitudinal driving device 6 is fixedly connected with the side vertical plate 1 and used for driving the rack 5 to move up and down, the upper end and the lower end of the side vertical plate 1 are provided with limiting buffer columns 11 for limiting the rack 5, and the second longitudinal driving device 7 is fixedly connected with the rack 5. The longitudinal telescopic adsorption head 8 is connected with the rack 5 through a longitudinal spring 12 for longitudinal telescopic, a first adsorption port 8a is arranged on the lower end face of the longitudinal telescopic adsorption head 8, the longitudinal spring 12 is sleeved on a hollow longitudinal guide pillar 13, the hollow longitudinal guide pillar 13 is guided by a connecting block 14 on the rack 5, and a first adsorption port 8a connected with an air suction pipeline is arranged in the hollow longitudinal guide pillar 13. The lower end of the longitudinal telescopic adsorption head 8 can move upwards to compress the longitudinal spring 12 when being pressed, and the first adsorption port 8a can ensure that the adhesive tape section 4 transferred by the adhesive tape carrying platform 3 is always adsorbed. The left side and the right side of the longitudinal telescopic adsorption head 8 are respectively provided with a fixed side block 9 and a movable side block 10, and the fixed side block 9 is a cuboid block tightly attached to the longitudinal telescopic adsorption head 8 and fixedly connected with the rack 5. The movable side block 10 is located below the second longitudinal driving device 7, the movable side block 10 is of a C-type with an opening facing the fixed side block, and comprises a front side plate 10a and a rear side plate 10b which are both of the C-type, the front side plate 10a and the rear side plate 10b are arranged at intervals to form a channel for guiding the adhesive tape section 4, and the channel ensures that the adhesive tape section 4 transferred by the adhesive tape carrying platform 3 can be accurately adsorbed by the longitudinal telescopic adsorption head 8 along the direction of the fixed side block 9-the longitudinal telescopic adsorption head 8-the movable side block 10. The upper end 10C of the C-shape is hinged with the frame 5, and the upper bent part 10d of the C-shape is hinged with the cylinder rod of the second longitudinal driving device 7 through a connecting rod 15. When the cylinder rod of the second longitudinal driving device 7 extends downwards, the movable side block 10 of the C-shaped structure rotates around the upper end head 10C of the C-shaped structure and enables the lower end head 10e of the C-shaped structure to approach the fixed side block 9, and when the cylinder rod of the second longitudinal driving device 7 retracts upwards, the movable side block 10 of the C-shaped structure rotates around the upper end head 10C of the C-shaped structure in the opposite direction and enables the lower end head 10e of the C-shaped structure to be far away from the fixed side block 9. The C-shaped lower end head 10e is provided with a rolling guide wheel 10f, the rotating shaft of the rolling guide wheel 10f is parallel to the side wall of the fixed side block 9 facing the movable side block 10, when the movable side block 10 is close to the fixed side block 9, the rolling guide wheel 10f can roll on the plastic pipe ring and the side wall of the fixed side block 9 to apply pressure, so that the adhesive tape is fully combined with the plastic pipe ring and the fixed side block, and the bundling is more reliable.
The working process of the device is as follows: firstly, the adhesive tape carrying platform 3 is driven by the triaxial moving mechanism 2 to carry the adhesive tape section 4 sent out by the adhesive tape feeding mechanism, the adhesive tape section 4 is adsorbed on the surface of the adhesive tape carrying platform 3, then the triaxial moving mechanism 2 further drives the adhesive tape carrying platform 3 to move to the position below the longitudinal telescopic adsorption head 8, the second adsorption port 3a of the adhesive tape carrying platform 3 releases negative pressure adsorption, the first adsorption port 8a of the longitudinal telescopic adsorption head 8 opens negative pressure adsorption, the adhesive tape section 4 is adsorbed to the longitudinal telescopic adsorption head 8 from the surface of the adhesive tape carrying platform 3, one end of the adhesive tape section 4 is positioned below the fixed side block 9, and the other end of the adhesive tape section 4 is positioned below the movable side block 10. Because the plastic pipe ring to be bundled is generally positioned below the longitudinal telescopic adsorption head 8, in order to avoid the plastic pipe ring three-axis moving mechanism 2 to drive the adhesive tape carrying platform 3 to move again, a space is reserved for the plastic pipe ring to leave the position below the longitudinal telescopic adsorption head 8. Then the first longitudinal driving device 6 drives the rack 5 to move downwards, the second longitudinal driving device 7, the longitudinal telescopic adsorption head 8, the fixed side block 9 and the movable side block 10 on the rack 5 integrally move downwards, after the longitudinal telescopic adsorption head 8 contacts a plastic pipe ring in the downward moving process, the longitudinal spring 12 is compressed, the adhesive tape section 4 adsorbed by the longitudinal telescopic adsorption head 8 is pressed on the upper surface of the plastic pipe ring, along with the further downward movement of the rack 5, the second longitudinal driving device 7 starts to drive the movable side block 10 to rotate so as to be close to the fixed side block 9, and then the adhesive tape under the movable side block 10 is attached around the plastic pipe ring until the movable side block 10 contacts the fixed side block 9, and the two ends of the adhesive tape are bonded to finish bundling.
