It is a narrow and long steel plate produced by various rolling mills to meet the needs of different industrial sectors for industrial production of various metal or mechanical products.

[0003] When producing steel strips, for the convenience of transportation, the formed steel strips are wound into a cylindrical shape by a coiler. However, the existing coiler does not have a protection mechanism. When the steel strip is coiled, the end of the steel strip is prone to collide with the coiler under the action of gravity and elasticity, causing damage to the surface of the steel strip or the machine. Therefore, we propose a control device for a movable protective cover. Content of the Utility Model

[0006] Preferably, two sets of the adjusting mechanisms are symmetrically arranged on the fixed plate. Circular grooves are formed through the surface of the clamping plate, and the diameter of the winding roller is smaller than that of the circular groove.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] The control device of the movable protective cover includes a fixed plate 1 and fixed columns 6. A first motor 2 is fixedly connected to the surface of the fixed plate 1. The output shaft of the first motor 2 is fixedly connected to a first rotating shaft 3. A winding roller 4 is fixedly connected to the surface of the first rotating shaft 3. An adjusting mechanism 5 is arranged on the surface of the fixed plate 1. The adjusting mechanism 5 includes a clamping plate 51. Two groups of adjusting bolts 52 are symmetrically and fixedly connected to the upper and lower surfaces of the clamping plate 51. Two groups of limiting rods 53 are symmetrically and fixedly connected to the left and right surfaces of the clamping plate 51. An adjusting nut 54 is movably connected to the surface of the adjusting bolt 52. The bottom of the fixed plate 1 is fixedly connected to a bottom plate. Two groups of fixed columns 6 are fixedly connected to one end of the bottom plate. A protection mechanism 7 is arranged inside the fixed column 6. The protection mechanism 7 includes a second motor 71. The output shaft of the second motor 71 is fixedly connected to a second rotating shaft 72. A first bevel gear 73 is fixedly connected to the surface of the second rotating shaft 72. A second bevel gear 74 is meshed with the surface of the first bevel gear 73 through teeth. A screw rod 75 is fixedly connected to the surface of the second bevel gear 74. A slider 76 is movably connected to the surface of the screw rod 75. A third rotating shaft 77 is fixedly connected to the surface of the slider 76. An auxiliary roller 78 is movably connected to the surface of the third rotating shaft 77. A connecting block 79 is fixedly connected to the surface of the slider 76. A side fixed frame 710 is fixedly connected to the surface of the connecting block 79. A protective roller 711 is fixedly connected to the surface of the side fixed frame 710. The protection mechanism 7 is provided. When the steel strip is wound on the surface of the winding roller 4, the second motor 71 drives the second rotating shaft 72 to rotate, so that the first bevel gear 73 rotates, driving the second bevel gear 74 to rotate, and the screw rod 75 thereon rotates. The slider 76 is driven to move through the thread on the surface, so that the side fixed frame 710 is driven to move through the connecting block 79, and the position of the protective roller 711 on the side fixed frame 710 is adjusted. When the end of the steel strip moves downward under the action of gravity and elasticity, it contacts the protective roller 711. The protective roller 711 is made of rubber and bears the impact force of the end of the steel strip. The end of the steel strip is received by the protective roller 711, preventing the end of the steel strip from colliding with the coiler and causing damage to the surface of the steel strip or the machine. The adjusting mechanism 5 and the auxiliary roller 78 are provided. When the steel strip is wound, the position of the clamping plate 51 can be changed by adjusting the adjusting bolt 52 and the adjusting nut 54, and steel strips with different diameters can be wound. The height of the auxiliary roller 78 is adjusted by driving the slider 76 to move through the rotation of the screw rod 75 by the second motor 71, so as to adjust the tension of the steel strip, and the applicability is good.

[0024] Further, two groups of the adjusting mechanism 5 are symmetrically arranged on the fixed plate 1. A circular groove is formed through the surface of the clamping plate 51. The diameter of the winding roller 4 is smaller than the diameter of the circular groove. The surface of the circular groove on the clamping plate 51 does not contact the surface of the winding roller 4, and the adjustment of the position of the clamping plate 51 will not be affected by the winding roller 4.

[0025] Further, the adjusting bolt 52 and the limiting rod 53 are arranged at intervals on the circumferential surface of the adjusting mechanism 5 with the center of the first rotating shaft 3 as the center of the circle. The length of the adjusting bolt 52 is greater than that of the limiting rod 53. Both the adjusting bolt 52 and the limiting rod 53 penetrate through the fixing plate 1 to prevent the limiting rod 53 from falling off the fixing plate 1.

[0026] Further, the second motor 71 is fixedly connected to the surface of a group of fixing columns 6. The first bevel gear 73, the second bevel gear 74, the screw rod 75, the slider 76, the connecting block 79 and the side fixing frame 710 form a group of protection components. There are two groups of protection components, and the position of the protection roller 711 and the height of the auxiliary roller 78 are adjusted through the protection components.

[0027] Further, first square grooves are formed on the surfaces of both groups of fixing columns 6. The two ends of the third rotating shaft 77 are respectively slidably connected in the two first square grooves. The two ends of the third rotating shaft 77 are respectively fixedly connected to the two sliders 76. When the slider 76 moves as the screw rod 75 rotates, the third rotating shaft 77 is driven to move.

[0028] Further, second square grooves are formed on the surfaces of both groups of fixing columns 6. The connecting block 79 is slidably connected in the second square grooves. When the slider 76 moves as the screw rod 75 rotates, the connecting block 79 is driven to move, and then the side fixing frame 710 and the auxiliary roller 78 thereon are driven to move.

[0029] Further, the cross-section of the side fixing frame 710 is fan-shaped. Four groups of protection rollers 711 are arranged at equal intervals along the curved edge of the side fixing frame 710. The height of the group of protection rollers 711 at the topmost position is lower than the height of the auxiliary roller 78. The protection rollers 711 are made of rubber material. The auxiliary roller 78 is higher than the four groups of protection rollers 711. When the steel coil is being wound up, the surface of the steel coil contacts the surface of the auxiliary roller 78 from above the auxiliary roller 78. Adjusting the height of the auxiliary roller 78 can adjust the tension of the steel strip.

[0030] Working principle: When winding up the steel strip, by adjusting the adjusting bolt 52 and the adjusting nut 54, the position of the clamping plate 51 can be changed, and steel strips with different diameters can be wound up. The adjusting bolt 52 and the adjusting nut 54 cooperate with each other to fix the position of the clamping plate 51. The second motor 71 drives the second rotating shaft 72 to rotate, causing the first bevel gear 73 to rotate, driving the second bevel gear 74 to rotate, and making the screw rod 75 thereon rotate. The slider 76 is driven to move through the thread on the surface, and thus the side fixing frame 710 is driven to move through the connecting block 79, adjusting the position of the protection roller 711 on the side fixing frame 710. When the end of the steel strip moves downward under the action of gravity and elasticity and contacts the protection roller 711, the protection roller 711 is made of rubber and bears the impact force of the end of the steel strip. At the same time, the height of the auxiliary roller 78 is adjusted by the movement of the slider 76, and the surface of the steel coil contacts the surface of the auxiliary roller 78 from above the auxiliary roller 78, and the tension of the steel strip can be adjusted.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
