Description

Technical Field

[0001] This utility model relates to the field of narrow-band unwinding technology, and in particular to a fully automatic unwinding machine. Background Technology

[0002] Steel strip, also known as steel belt, is a narrow and long flat steel material. When using steel strip, it is usually handled manually, with each coil of strip removed and placed on an unwinding rack for equipment use. However, this feeding method has several drawbacks: First, because each coil of steel strip is narrow, it is prone to breakage not only during individual coil removal but also during unwinding, which is dangerous and affects packaging efficiency. Second, since the bottom of the steel strip is in direct contact with the unwinding rack, it is easily worn down by the equipment as it is continuously pulled out, affecting packaging quality and reducing the lifespan of the steel strip. Third, the steel strip is always in a passive state during the pulling process and cannot precisely synchronize with the equipment, further increasing the probability of breakage. Fourth, packaging efficiency is low; after each coil of steel strip is used, it needs to be replaced manually, which is time-consuming and labor-intensive, resulting in low work efficiency and severely slowing down the overall packaging efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a fully automatic unwinding machine. It features a reasonable structural design and convenient operation, replacing manual material handling with mechanical transmission for feeding, saving time and labor, effectively freeing up manpower, avoiding the risk of strip breakage during individual handling of steel strips, and significantly shortening the time for steel strip replacement. This allows the equipment to operate continuously, greatly improving work efficiency and packaging efficiency. During the unwinding process, the steel strip can be effectively limited to prevent breakage. Furthermore, by actively controlling the unwinding speed, it transforms passive operation into active operation, allowing for precise synchronization with the equipment and further reducing the probability of breakage.

[0035] Optionally, the lateral drive mechanism includes a lateral screw jack 25 horizontally arranged between two lateral guide rails 2. The screw of the lateral screw jack 25 is arranged parallel to the lateral guide rails 2. A fixing seat 26 for fixing the base of the lateral screw jack 25 is provided on the fixing base plate 1 at the right end of the lateral guide rails 2. A bearing seat 27 for engaging the screw of the lateral screw jack 25 is provided on the fixing base plate 1 at the left end of the lateral guide rails 2. A linkage seat 28 for fixing the nut of the lateral screw jack 25 is provided at the bottom of the lateral base plate 4. A lateral motor 29 is provided on the lateral screw jack 25.

[0036] Optionally, the limiting and abutting mechanism includes a front baffle 46 arranged parallel to the rear baffle 6. The gap formed between the front baffle 46 and the rear baffle 6 is used for the steel strip to be inserted. A support platform 30 connected to the fixed base plate 1 is provided on the front side wall of the front baffle 46. Both the left and right side walls of the front baffle 46 are bent forward to facilitate smoother insertion of the steel strip.

[0037] Optionally, the feeding mechanism includes a rotating base 31 mounted on a fixed base plate 1, a worm gear rotary drive 32 mounted on the top of the rotating base 31, the worm gear rotary drive 32 having its worm gear turntable connected to a rotating base plate 33 horizontally mounted above the rotating base 31, and a horizontally mounted support frame fixedly mounted on the rotating base plate 33. The support frame includes two vertically and parallel longitudinal beams 34, which are perpendicular to the rear baffle 6 and positioned within the limiting circular hole 12. Round steel bars 35 are mounted on the top of the two longitudinal beams 34 extending from both sides of the rotating base plate 33 along their length. Pushing mechanisms are symmetrically mounted at the front and rear ends of the support frame.

[0038] Optionally, the pushing mechanism includes a pushing screw jack 36 mounted on a rotating base plate 33. A connecting plate 37 is provided on the inner side wall of two longitudinal beams 34 on the outer side. The base of the pushing screw jack 36 is located between the two longitudinal beams 34. Its screw is parallel to the round steel 35, and the end of the screw is movably engaged with the connecting plate 37. Pushing guide rails 38 are provided on the outer side walls of the two longitudinal beams 34 along their length. A pushing plate 39 is movably mounted on a support frame. Pushing channels 40 are provided on the left and right sides of the pushing plate 39 for the longitudinal beams 34, the round steel 35, and the pushing guide rails 38 to pass through. The nut of the pushing screw jack 36 is fixed to the center of the pushing plate 39. Pushing sliders 41 are provided on the pushing plate 39 corresponding to the two pushing channels 40, and are slidably engaged with the corresponding pushing guide rails 38. A pushing motor 45 is provided on the pushing screw jack 36.

[0039] Optionally, limiting mechanisms are provided at the ends of the two longitudinal beams 34. Each limiting mechanism includes a limiting block 42 mounted on the outer wall of the longitudinal beam 34. The upper part of the limiting block 42 is connected to a circle 35 on the corresponding side. A push-pull electromagnet 43 is installed inside the limiting block 42. When the clamping drive mechanism clamps a reel of steel strip, it can control the push-pull electromagnet 43 to extend its telescopic column outwards, thereby limiting other steel strips placed on the feeding mechanism. This prevents the strips from slipping outwards when the pushing mechanism pushes other reels of steel strips to move outwards.

[0040] Optionally, rubber blocks 44 are provided at the four corners of the outer side wall of the push plate 39. When the packing tray is installed onto the support frame, the rubber blocks 44 can relieve the force to reduce the impact on the push plate 39. Furthermore, when the push plate 39 pushes the steel strip outward, the rubber blocks 44 can also act as a buffer, so that the force is applied to the packing tray slowly.

[0041] Before using this device, the coiled steel strip needs to be placed on the feeding mechanism, so that the coiled steel strip is clamped onto the support frame at the front end of the rotating base 31 and abuts against the rubber blocks 44 of the push plate 39. Then, the worm gear rotary drive 32 is started, causing it to rotate the rotating base plate 33 horizontally by 180 degrees and then stop. At this time, another coil of steel strip can be installed on the support frame on this side and abut against the rubber blocks 44 of the push plate 39 on this side.

[0042] In use, the lateral drive mechanism drives the clamping drive mechanism to move, starting the lateral motor 29. The lateral motor 29 drives the lateral screw jack 25 to start, causing its screw to rotate radially. This, in turn, drives the linkage seat 28 to move via the nut. As the linkage seat 28 moves, the lateral base plate 4 slides to the left along the lateral guide rail 2 until the limit hole 12 is aligned with the support frame, at which point the lateral motor 29 stops. Then, the chuck displacement motor 14 is controlled to work, and its output shaft drives the displacement worm 15 to rotate, which in turn drives the displacement worm wheel 17 meshing with it to rotate. As the displacement worm wheel 17 rotates, it drives the displacement sleeve 16 to move forward. The displacement sleeve 16 drives the mechanical chuck 11 to move synchronously through the connecting plate 19 and the gear chuck 21 until the mechanical chuck 11 extends into the inner wall of the steel strip (it should be noted that during the forward and backward movement of the mechanical chuck 11, the front end of the central shaft 10 is always engaged inside the mechanical chuck 11). At this point, while stopping the chuck displacement motor 14, the chuck motor 9 is started. The output shaft of the chuck motor 9 drives the central shaft 10 to rotate, thereby controlling the jaws on the mechanical chuck 11 to extend outwards and abut against the inner wall of the steel strip. Then, the chuck motor 9 is stopped, and the chuck displacement motor 14 is started in reverse, causing the mechanical chuck 11, which is holding a coil of steel strip, to return to its initial position. Next, the transverse movement motor 29 is started in reverse, causing the clamping drive mechanism to return to its original position and move to the side of the limit abutment mechanism. At this point, the packing coil is fully engaged in the gap formed by the rear baffle 6 and the front baffle 46, effectively controlling the phenomenon of coil breakage during unwinding.

[0043] Then, the control chuck rotation motor 22 is activated, and its output shaft drives the pinion 24 to rotate through the planetary reducer 23, which in turn drives the gear chuck 21 meshing with it to rotate. The gear chuck 21 then drives the mechanical chuck 11 to rotate, thus achieving the function of active unwinding.

[0044] When all the steel strip at the rear end of the support frame is used up, the worm gear rotary drive 32 can be activated to rotate the rotating base plate 33 180 degrees, moving the support frame with the steel strip at the front end to the side of the clamping drive mechanism without interrupting the clamping process. At this point, the empty support frame at the front end can simply be reloaded with the coiled steel strip. Its reasonable structural design and convenient operation, using mechanical transmission for feeding instead of manual handling, saves time and labor, effectively freeing up manpower and avoiding the risk of strip breakage during individual coil handling. It also effectively shortens the time for changing steel strips, allowing the equipment to work continuously and greatly improving work and packaging efficiency. During unwinding, the steel strip can be effectively limited to prevent breakage. Furthermore, by actively controlling the unwinding speed, it transforms passive operation into active operation, precisely synchronizing with the equipment to further reduce the probability of breakage. Simultaneously, the steel strip is unwound in a suspended manner, preventing wear and tear on the steel strip, not affecting packaging quality, and extending the service life of the steel strip, thus solving problems existing in current technologies.

[0045] This device is not only used for the unwinding process of steel strips, but also applicable to other types of narrow strips.
