Description

Technical Field

[0001] The utility model relates to the technical field of uncoiler structures, and specifically relates to an uncoiler diameter increasing mechanism. Background Art

[0002] An uncoiler is a special equipment for leveling metal sheets. It can be used for leveling steel plates in a leveling line. Uneven plates can form an uncoiling, leveling, and shearing production line and other sheet metal product production lines according to relevant configurations. It is applicable to industries such as machinery, vehicles, metal products, household appliances, steel structures, and decoration.

[0003] Generally, an uncoiler is provided with a diameter increasing mechanism for supporting coils. For example, an uncoiler diameter increasing device with the patent publication number CN218963665U. It sleeves the steel coil outside the diameter increasing ribs and starts the hydraulic rod. The hydraulic rod starts to extend and drives the sector block to move. The movement of the sector block drives the diameter increasing plate to move. The movement of the diameter increasing plate drives multiple diameter increasing ribs to move. The movement of the diameter increasing ribs achieves the effect of supporting the inner wall of the steel coil. At the same time, by setting a rubber strip on one side of the diameter increasing rib, the effect of preventing the diameter increasing rib from wearing the inner wall of the steel coil can be achieved.

[0004] However, the hydraulic mechanism relied on by this device has high cost, complex structure, and poor reliability. Content of the Utility Model

[0023] Embodiment

[0024] Please refer to Figures 1-4 , a diameter-increasing mechanism for an uncoiler, including an annular column 1, a movable sleeve 2, a top support frame 3, an inclined angle frame 4, a tapered block 5, a sliding sleeve 6, a connecting frame 7, a reciprocating motor 8, a threaded rod 9, and a threaded tube 10. Multiple groups of movable sleeves 2 are evenly connected to the circumferential side of the annular column 1. The inner side of each group of movable sleeves 2 is respectively slidably connected to the outer side of a group of top support frames 3. The inner ends of each group of top support frames 3 are respectively connected to the outer ends of a group of inclined angle frames 4. The rear end of the annular column 1 is connected to the front side of the outside of the reciprocating motor 8 through the connecting frame 7. The output end of the reciprocating motor 8 is connected to the front end of the threaded rod 9. The outer wall of the threaded rod 9 is screwed to the inner wall of the threaded tube 10. The outer side of the threaded tube 10 is connected to the inner side of the tapered block 5. Multiple groups of sliding sleeves 6 are evenly arranged on the outside of the tapered block 5. The outer side of each group of sliding sleeves 6 is respectively slidably connected to the inner side of the corresponding inclined angle frame 4; the annular column 1 is fixed at the corresponding position of the uncoiler. When in use, the coil is sleeved outside the annular column 1, and then the reciprocating motor 8 operates. Under the connection of the connecting frame 7, the threaded rod 9 rotates. Due to the sliding restraint of the multiple groups of inclined angle frames 4 on the sliding sleeves 6, the circumferential fixation of the tapered block 5 and the threaded tube 10 can be realized. The threaded rod 9 is screwed with the threaded tube 10, so that the threaded tube 10 drives the tapered block 5 to move longitudinally. At the same time, through the sliding cooperation of the multiple groups of sliding sleeves 6 and the corresponding inclined angle frames 4, the inclined angle frames 4 drive the top support frames 3 to move outward inside the movable sleeves 2, so as to act on the inner support of the coil, and after the reciprocating motor 8 stops rotating, it is fixed by the screw self-locking of the threaded rod 9 and the threaded tube 10.

[0025] It further includes a top contact pad 11. The outer side of each group of top support frames 3 is respectively connected to the inner side of a group of top contact pads 11; the outer sides of the multiple groups of top contact pads 11 can be in contact with the inner wall of the coil, avoiding slipping and improving stability.

[0026] It further includes a limiting piece 12. A group of limiting pieces 12 are respectively connected to the front parts of the inner sides of each group of inclined angle frames 4, and all the limiting pieces 12 are in the same circumferential position; the multiple groups of limiting pieces 12 can limit the front side of the sliding sleeve 6 at this position, avoiding over-positioning and improving reliability.

[0027] It further includes a corrugated sheath 13. The front outer side of the reciprocating motor 8 is connected to the rear end of the corrugated sheath 13; the corrugated sheath 13 can wrap the outside of the threaded rod 9, avoiding dust adhesion and pollution on its outside and improving reliability.

[0028] It further includes an oil filling nozzle 14. The oil filling nozzle 14 is arranged on the upper side of the rear end of the conical block 5, and the output end of the oil filling nozzle 14 is communicated with the inner wall of the threaded pipe 10. The inner wall of the threaded pipe 10 can be filled with oil through the oil filling nozzle 14, which is convenient for lubrication and maintenance.

[0029] It further includes an oil filling cap 15. The outer side of the oil filling nozzle 14 is detachably installed with the inner side of the oil filling cap 15. After the oil filling cap 15 is installed on the outer side of the oil filling nozzle 14, the inside of the oil filling nozzle 14 can be hermetically protected, improving reliability.

[0030] In summary, when an unwinding machine diameter increasing mechanism is in use, the annular column 1 is fixed at the corresponding position of the unwinding machine. During use, a coil is sleeved outside the annular column 1, and then the reciprocating motor 8 operates. Under the connection of the connecting frame 7, the threaded rod 9 rotates. Due to the sliding restraint of the multi-group inclined angle frames 4 on the sliding sleeve 6, the circumferential fixation of the conical block 5 and the threaded pipe 10 can be achieved. The threaded rod 9 is screwed with the threaded pipe 10, so that the threaded pipe 10 drives the conical block 5 to move longitudinally. At the same time, through the sliding fit of the multi-group sliding sleeves 6 and the corresponding inclined angle frames 4, the inclined angle frames 4 drive the top support frame 3 to move outward inside the movable sleeve 2, thereby acting on the inner support of the coil. The outer sides of the multi-group top pressing contact pads 11 can contact the inner wall of the coil to avoid slipping. After the reciprocating motor 8 stops rotating, it is self-locked by the threaded rod 9 and the threaded pipe 10. In addition, the multi-group limiting pieces 12 can limit the front side of the sliding sleeve 6 at this position to avoid over-positioning. The corrugated sheath 13 can wrap the outside of the threaded rod 9 to avoid external dust adhesion and pollution. The inner wall of the threaded pipe 10 can be filled with oil through the oil filling nozzle 14, which is convenient for lubrication and maintenance. After the oil filling cap 15 is installed on the outer side of the oil filling nozzle 14, the inside of the oil filling nozzle 14 can be hermetically protected, improving reliability.

[0031] This reciprocating motor 8 is a well-known device directly purchased in the market by those skilled in the art. Here we only use it and do not make improvements to its structure and function, so we will not elaborate on it in detail here.
