Specifically, the cutter mechanism 30 is located in the middle of the two horizontal joint mechanisms 40, so as to facilitate cutting the inner tube joint end, so as to facilitate combining the two cut ends together through the horizontal joint mechanism 40. In addition, the pressure roller assembly 60 is installed on the joint table 50 to achieve the purpose of leveling the inner tube.

The output shaft of the first cylinder 310 is connected to the first lifting plate 320. A U-shaped cutter 330 is fixedly installed at the bottom of the first lifting plate 320. When set, a discharge port is also opened at the top of the device body 10. The U-shaped cutter 330 is driven downward by the first cylinder 310 to cut the two ends of the inner tube joint, so that the cut waste falls to the discharge port to be discharged from the discharge port.

[0023] See also Figure 1 The horizontal joint mechanism 40 includes a second cylinder 410 installed on one side of the bracket 20, and the conveying shaft of the second cylinder 410 is connected to the horizontal movable frame 420. The joint table 50 is slidably arranged on the device body 10 and is fixedly connected to one end of the horizontal movable frame 420. It should be noted that after the U-shaped cutter 330 cuts the inner tube joint end, it will move upward and reset. At this time, the second cylinder 410 passes through the horizontal movable frame 420, driving the two joint tables 50 to move toward each other, so that the two joint ends of the inner tube are fitted and bonded together.

[0024] See also Figure 1 and 3 The horizontal joint mechanism 40 also includes a third cylinder 430 installed on the horizontal moving frame 420, and the output shaft of the third cylinder 430 is connected to the second lifting plate 450. The bottom of the second lifting plate 450 is installed with an electric heating block 440. In the specific setting, before cutting the joint end of the inner tube, the third cylinder 430 passes through the second lifting plate 450, drives the electric heating block 440 to move downward, and presses on the inner tube, which can press the inner tube and heat the inner tube, so as to facilitate the U-shaped cutter 330 to cut the joint end of the inner tube, so that after the incisions of the two joint ends of the inner tube are fitted, the fitted incision ends are bonded due to the heating effect to complete the inner tube joint processing.

[0025] See also Figure 3 The top of the joint platform 50 is provided with an inner tube limiting groove 510 and a mounting groove 520, and a heating block 530 is embedded in the bottom of the inner tube limiting groove 510. The pressure roller assembly 60 includes a lower pressure roller 610 rotatably connected to the mounting groove 520, and the pressure roller assembly 60 also includes an upper pressure roller 620 hinged on the side wall of one end of the mounting groove 520, and the side wall of one end of the upper pressure roller 620 is clamped on the side wall of the other end of the mounting groove 520. It should be noted that the heating block 530 is arranged opposite to the electric heating block 440, so that the heating block 530 fixes the inner tube on the electric heating block 440 to achieve the purpose of jointly heating the inner tube. At the same time, the inner tube limiting groove 510 is used to place the inner tube and achieve the purpose of positioning the inner tube, so as to dock the interfaces at both ends of the inner end.

[0026] See also Figure 4, a hinge groove 70 and a clamping groove 710 are respectively provided on the side walls at both ends of the installation groove 520, and the tops of the hinge groove 70 and the clamping groove 710 are both open.

Two limit blocks 90 are installed on the top of the joint platform 50, and the two limit blocks 90 are respectively located on both sides of the clamping groove 710, and the same limit plate 910 is slidably penetrated thereon, and the limit plate 910 is contacted with the top of the connecting block 80. Specifically, the hinged structure between the connecting block 80 and the hinge groove 70 is the existing technology, so that the inner tube connection The head end passes through the middle of the upper pressure roller 620 and the lower pressure roller 610 to achieve the purpose of preliminary leveling of the inner tube joint end, so that when the heating block 530 presses the inner tube joint end downward, no wrinkles will appear to avoid affecting the inner tube joint process. After the inner tube joint is completed, the limit plate 910 can be pushed to disengage the limit plate 910 from the connecting block 80, so that the upper pressure roller 620 can be flipped upward to facilitate the removal of the annular inner tube. It should be noted that both limit blocks 90 are provided with through openings, so that the limit plate 910 can pass through the two through openings, thereby limiting the connecting block 80 on one side. At the same time, a push block is installed on the top of the limit plate 910 to facilitate pushing the limit plate 910 to move.

After the inner tube end extends out of the inner tube limiting groove 510, the third cylinder 430 can be started to make the second lifting plate 450 drive the electric heating block 440 to move downward, so that the inner tube joint end is pressed on the heating block 530 to fix the inner tube joint. At the same time, the electric heating block 440 and the heating block 530 are powered on to achieve heating treatment of the inner tube joint end, and then the first cylinder 310 can be started. , so that the first lifting plate 320 drives the U-shaped cutter 330 to move downward to cut the two ends of the inner tube.
