Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel strip unwinding machines, in particular to a coil-collapse prevention structure for unwinding strip steel. Background Art
[0002] After the cold-rolled silicon steel ultra-thin coil rotates and enters the working state, the steel coil will gradually relax and slip during the uncoiling process, resulting in coil collapse; especially when the steel coil is getting smaller and smaller, the last steel strip will rotate with the reel and slip into the gap between the reel fan plate and the baffle plate, causing the steel strip to wrinkle and tear, resulting in waste coils, reducing the output of finished coils and increasing costs.
[0003] After searching, it was found that a supporting equipment of a strip steel uncoiler with application number 2009201726405 includes a transverse cylinder, a box body, a fixed push plate, a reel, a swing arm assembly fixed on the box body, a push plate assembly connected to the reel, and a push plate support rail. By clamping and positioning both sides of the strip steel coil on the uncoiler reel, the strip steel coil on the uncoiler reel cannot collapse, which will not cause the scrapping of the steel coil and ensure the normal use of the uncoiler, which not only saves production costs but also improves work efficiency.
[0004] Although this device solves the problems of slippage and coil collapse when the strip is uncoiled, the push plate assembly used to prevent collapse has a complex structure and cumbersome operation, which increases additional energy consumption. At the same time, the push plate assembly used is greatly modified, and the existing uncoiler needs to be modified to a large extent, resulting in poor overall adaptability. Therefore, it is necessary to solve the problems that still exist in the prior art. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model provides a coil collapse prevention structure for strip steel after uncoiling, which solves the problem that when the supporting equipment of the existing strip steel uncoiling machine is used, the push plate assembly used has a complex structure, cumbersome operation, and increases additional energy consumption. At the same time, the degree of modification of the existing uncoiling machine needs to be increased, resulting in poor overall adaptability.
[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a coil-proof structure for strip steel after uncoiling, comprising a reel, the outer surface of the reel is fixedly connected to a fan-shaped plate, a boss is provided on one side of the outer surface of the fan-shaped plate, the outer surface of the boss is fixedly connected to a block, the outer surface of the reel is fixedly connected to a crosshead, the outer surface of the crosshead is fixedly connected to a baffle, and the outer surface of the baffle is movably connected to the outer surface of the baffle.
[0007] Preferably, a guide groove is provided on the outer surface of the baffle plate, and the interior of the guide groove is movably connected to the outer surface of the baffle.
[0008] Preferably, the fan-shaped plate and the boss are integrally formed.
[0009] Beneficial Effects
[0010] The utility model provides a coil-collapse prevention structure for strip steel after uncoiling. Compared with the prior art, it has the following beneficial effects:
[0011] The utility model utilizes a new design structure style in the existing structure to prevent the steel coil from sliding into the gap between the reel and the baffle plate. By changing the shape and structure of the fan-shaped plate, a boss of a certain height is added to the rear end of the fan-shaped plate, and a guide block is fixed on the boss. When the steel coil slides up and down along the end face of the crosshead, the fan-shaped plate with a new structure with a boss and the connected block can effectively prevent the inner ring of the steel coil from sliding. When designing the baffle plate, the baffle plate is placed at a corresponding position according to the block on the end face of the redesigned fan-shaped plate, and a structure with a guide groove is reserved. This can not only prevent the steel coil from collapsing, but also eliminate the gap between the reel and the baffle plate. When the steel coil slides along the reel axis, the steel strip can also be prevented from entering the gap between the fan-shaped plate and the baffle plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1 The utility model provides a technical solution: a coil-collapse prevention structure for strip steel after uncoiling:
[0016] The utility model comprises a reel 1, which is the reeling drum part of the existing uncoiler, a sector plate 2 is fixedly connected to the outer surface of the reel 1, a boss 3 is arranged on one side of the outer surface of the sector plate 2, a block 4 is fixedly connected to the outer surface of the boss 3, a cross head 5 is fixedly connected to the outer surface of the cross head 5, a baffle 6 is fixedly connected to the outer surface of the baffle 6, and the outer surface of the baffle 6 is movably connected to the outer surface of the block 4.
[0017] A new design structure is used to prevent the steel coil from sliding into the gap between the reel 1 and the baffle 6. By changing the shape and structure of the fan plate 2, a boss 3 of a certain height is added to the rear end of the fan plate 2, and a guide block 4 is fixed on the boss 3. When the steel coil slides up and down along the end face of the crosshead 5, the fan plate 2 with the new structure of the boss 3 and the connected block 4 can effectively prevent the inner ring of the steel coil from slipping. At the same time, when designing the baffle 6, the baffle 6 is placed in the corresponding position according to the block 4 on the end face of the redesigned fan plate 2, and a structure with a guide groove 7 is reserved. This not only prevents the steel coil from collapsing, but also eliminates the gap between the reel 1 and the baffle 6. When the steel coil slides along the reel 1, it can also prevent the steel strip from entering the gap between the fan plate 2 and the baffle 6.
[0018] A guide groove 7 is provided on the outer surface of the baffle plate 6, and the interior of the guide groove 7 is movably connected to the outer surface of the stop block 4. The guide groove 7 is used to fix the baffle plate 6 and the stop block 4, which can not only prevent the steel coil from collapsing, but also eliminate the connection gap between the baffle plate 6 and the fan plate 2.
[0019] The fan-shaped plate 2 and the boss 3 are integrally formed by a mold, so that the surface of the fan-shaped plate 2 in contact with the strip steel is staggered with the surface in contact with the baffle plate 6, avoiding the problem of waste coils caused by the collapse of the steel strip due to the existence of gaps.
[0020] The unwinding reel anti-collapse baffle 6 device designed by the utility model effectively prevents the strip steel from slipping into the gap between the reel 1 and the baffle 6 during production, reduces the loss and defective rate of the strip steel, and improves the production efficiency in the CT units of Anshan Silicon Steel Plant and Wuhan Iron and Steel Silicon Steel Plant, bringing very ideal results.
