Description

Technical Field

[0001] This utility model relates to the field of aluminum foil sheath tube production technology, and in particular to a rolling machine for producing aluminum foil sheath tubes. Background Technology

[0002] Aluminum foil sheathing is a flexible sheath used to protect cables, pipes, or equipment. It is mainly made of aluminum foil material and is usually combined with other materials (such as polyester fiber, glass fiber, or adhesives) to enhance its performance.

[0003] During the production of aluminum foil sheathing tubes, aluminum foil sheets are typically processed into cylindrical shapes using a rolling machine. A rolling machine is a mechanical device used to bend metal sheets (such as steel plates, aluminum plates, etc.) into circular or arc-shaped workpieces, and is widely used in industries such as pipe manufacturing, storage tanks, air ducts, and steel structures. The rolling machine applies continuous bending force, causing the metal sheet to gradually curl and take shape along the rollers.

[0004] Currently, after the aluminum foil sheath tube is rolled into a round shape, the fixing pin on the movable side plate of the machine needs to be pulled out, and then the movable side plate is laid horizontally so that one end of the movable side plate is separated from one end of the pressure roller. Then the pressure roller is raised, and then the rolled aluminum foil sheath tube is unloaded, which is quite troublesome. Utility Model Content

[0029] The limiting component includes two symmetrically fixed blocks 19 fixed on the top surface of the base 1. The second slot 26 is located between the two fixed blocks 19. The outer side of one of the fixed blocks 19 is horizontally penetrating through a through slot 21. A wedge block 20 is slidably connected in the through slot 21. The end of the wedge block 20 abuts against the inner side of the other fixed block 19, and the lower inclined surface of the wedge block 20 abuts against the upper edge of the support shaft 27. The end of the wedge block 20 is fixedly connected to an elastic element, which is slidably connected to the outer surface of the fixed block 19.

[0030] The elastic element includes a support plate 22 fixed to the end of the wedge block 20. Two guide rods 24 are symmetrically slidably sleeved on the outside of the support plate 22.

The iron block 30 is slidably connected inside the magnetic shielding sleeve 31 and fixedly connected to the support plate 22.

[0031] By connecting the pressure roller 3 to the two guide rollers 2 via a drive component, and rotatably connecting the pressure roller 3 to the top surface of the base 1 via a support component, a lifting component, a limiting component, and an elastic component, the lifting component drives the pressure roller 3 to rise, causing the pressure roller 3 to leave the limiting component and the second slot 26. This facilitates the removal of the rolled workpiece from the pressure roller 3, eliminating the need to flip down the movable side plate of the equipment and then lift the pressure roller 3 to remove the workpiece. This reduces the number of operation steps and improves the processing efficiency of the equipment for aluminum foil sheath tubes, while also enhancing the ease of operation.

[0032] Working principle: In use, the aluminum foil sheet to be rolled is inserted into the gap between the guide roller 2 and the pressure roller 3. Then, the drive motor 4 drives the first pulley 6 to rotate. The first pulley 6 drives the second pulley 7 to rotate via the belt 5. The second pulley 7 drives the corresponding first gear 8 to rotate. The first gear 8 drives the guide roller 2 to rotate. At the same time, the first gear 8 drives the second gear 9 meshing with it to rotate. The second gear 9 drives the pressure roller 3 to rotate. The second gear 9 drives the second guide roller 2 to rotate via another first gear 8. The two guide rollers 2 and the pressure roller 3 work together to rotate the aluminum foil sheet. The aluminum foil sheet is rolled into a circle. After the rolling is completed, the electromagnetic block 29 is de-energized, and the magnetic force disappears. At this time, the iron block 30 is in a loose state with the electromagnetic block 29. Then, the lead screw motor 13 drives the screw 14 to rotate. When the screw 14 rotates, it drives the guide block 17 to rise. When the guide block 17 rises, it drives the rotating seat 16 to rise. The rising of the rotating seat 16 drives the pressure roller 3 to rise. The pressure roller 3 drives the support shaft 27 to rise, so that the support shaft 27 leaves the second slot 26. When leaving, the support shaft 27 will drive the wedge block 20 to move towards the through slot 21 under the action of the inclined surface at the lower end of the wedge block. The movement causes the support shaft 27 to pass between the two fixed blocks 19, while the spring 25 is compressed, causing the iron block 30 to leave the magnetic shielding sleeve 31 and separate from the electromagnetic block 29. After the support shaft 27 leaves between the two fixed blocks 19, the spring 25 returns to its original position, causing the wedge block 20 to return to its original position. At this time, the height of the pressure roller 3 will be higher than the height of the fixed blocks 19. Then, the aluminum foil sheath tube on the outer edge of the pressure roller 3 is removed from the outer edge of the pressure roller 3, and then the pressure roller 3 descends to its original position. When the pressure roller 3 descends to its original position, the support shaft 27 will press against the inclined surface at the upper end of the wedge block 20. Under the elastic action of spring 5, the wedge block 20 is driven to move again toward the through groove 21, so that the support shaft 27 passes through the two support blocks and is engaged in the second slot 26. After the support shaft 27 is engaged in the second slot 26, the wedge block 20 returns to its original position under the elastic action of spring 25. At the same time, the inclined surface of the lower edge of the wedge block 20 abuts against the outer edge of the support shaft 27, and the iron block 30 returns to the magnetic sleeve 31 and contacts the electromagnetic block 29. Then the electromagnetic block 29 is energized, so that the electromagnetic block 29 attracts and fixes the iron block 30 through magnetic force, so that the wedge block 20 is fixed between the two fixed points.
