[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1 and Figure 2 The embodiment of the present invention provides a strip steel coiling device, which is mainly used to cooperate with the reel 6 of the coiler to assist the reel 6 in coiling the strip steel. The strip steel coiling device includes a frame 2, the frame 2 has a storage groove that can accommodate the reel 6, the frame 2 is provided with a belt running roller system, a coiling belt 51 wound on the belt running roller system, and an arm mechanism 4 for assisting the reel 6 in winding when winding. The opening of the storage groove is used to accommodate the reel 6 on the one hand, and on the other hand, the strip steel enters the storage groove through the opening and is coiled by the reel 6; in the process of the storage groove accommodating the reel 6, the coiling belt 51 contacts the reel 6 and forms a certain wrap angle to wrap around the reel 6, so that a strip steel entrance 7 is formed between the coiling belt 51 and the reel 6, which is used to bite the strip head to facilitate the coiling of the strip steel.

[0025] In a preferred embodiment, Figure 1 and Figure 2 The strip steel coiling device also includes a coiling trolley 1. The frame 2 is mounted on the coiling trolley 1. The coiling trolley 1 can travel in both directions and has an online position and an offline position, that is, the coiling trolley 1 can run between the online position and the offline position, and does not affect other operations of the coiler after completing the coiling function. The traveling mechanism of the coiling trolley 1 can adopt conventional forms such as rollers; the running power of the coiling trolley 1 can be driven by a conventional motor; in another embodiment, a driving track (illustrated, not marked) is arranged on the workshop structure platform, and the coiling trolley 1 travels on the driving track and can be driven by conventional linear drive devices such as hydraulic cylinders and air cylinders. Generally speaking, the strip steel coiling device only needs to assist the reel 6 to complete the coiling of a certain length of the strip head. Usually, the coiling work is completed after the strip head is wound around the reel 6 for 3 to 5 turns and the initial coiling tension is established; after the coiling work is completed, the coiling trolley 1 can be returned to the offline position.

[0026] The belt running roller system is used to support and tension the auxiliary winding belt 51 and enable the auxiliary winding belt 51 to circulate and run smoothly. Obviously, the belt running roller system can guide the auxiliary winding belt 51 to pass through the above-mentioned storage groove and then return to the frame 2 for circulation. Figure 2Preferably, the belt running roller system includes a plurality of support rollers 52, at least one tensioning roller (not shown) and a steering roller 53 installed at the output end of the arm-holding mechanism 4, wherein each support roller 52 is installed on the frame body 2; in one embodiment, each support roller 52 is a crowned roller with a crown, which can make the auxiliary winding belt 51 self-correct and prevent deviation; in another embodiment, each support roller 52 can also be a combination of a crowned roller and a flat roller; each tensioning roller is installed on the frame body 2, which can provide tension to the auxiliary winding belt 51 to ensure the smooth operation of the auxiliary winding belt 51. In an optional embodiment, the support rollers 52 and the tensioning rollers can be equipped with roller seat driving components to improve their respective functions. The specific structure is a conventional configuration in the field and is not described here.

[0027] The arm mechanism 4 is mainly used to assist the reel 6 in coiling the strip steel. The steering roller 53 installed on the arm mechanism 4 cooperates with other belt rollers to allow the auxiliary winding belt 51 to be wrapped around the reel 6. Specifically, Figure 1 and Figure 2 The arm-holding mechanism 4 includes an arm-holding driving unit 42 and an arm-holding frame 41 rotatably mounted on the frame 2, the steering roller 53 is mounted on the arm-holding frame 41, and the arm-holding frame 41 is connected to the arm-holding driving unit 42 so as to have an engaged state and an open state; in the engaged state, the arm-holding frame 41 drives the steering roller 53 to swing close to the reel 6 and make the belt wrap angle on the reel 6 the target value; in the open state, the arm-holding frame 41 is away from the reel 6. The arm-holding driving unit 42 can be driven by a hydraulic cylinder, a cylinder or other driving device, and its housing is preferably hinged on the frame 2, and its output end is preferably hinged with the arm-holding frame 41, so that the arm-holding frame 41 can swing in a vertical plane so as to approach or move away from the reel 6 (that is, switch between its engaged state and its open state). In actual operation, the swing angle of the arm-holding frame 41 can be controlled by the arm-holding driving unit 42 to control the wrap angle of the auxiliary winding belt 51 on the reel 6, thereby ensuring the coiling effect of the strip. Further preferably, the above-mentioned arm frame 41 is arranged on the lower side of the front end of the frame 2, and it can be swung from the open side of the storage groove to close to the reel 6. While the auxiliary winding belt 51 wraps around the reel 6, it can partially block the opening of the storage groove, thereby forming an embracing posture for the reel 6 in space, and the strip steel and the reel 6 are tightly fitted through the auxiliary winding belt 51.

[0028] More preferably, if Figure 2, a pressing plate 43 is also installed on the arm frame 41. In the embracing state, the pressing plate 43 is close to the reel 6 and cooperates with the reel 6 to form a strip head guide channel. The pressing plate 43 is arranged at one end of the arm frame 41 away from the arm drive unit 42; in the above structure, after the auxiliary winding belt 51 wraps around the reel 6, the auxiliary winding belt 51 and the reel 6 form a strip steel entrance 7 and a strip steel exit, wherein the strip steel exit is close to the open side of the storage slot, and the pressing plate 43 can swing to the strip steel exit side with the arm frame 41, mainly used to guide the strip steel, so that the strip steel, especially the strip head, is close to the reel 6 and is easy to be coiled. For example, in general, the strip enters the storage tank from the opening of the storage tank in a downwardly inclined manner and is bitten by the winding belt 51 and the reel 6 through the strip entrance 7. In the engaged state, the above-mentioned pressure plate 43 is located above the reel 6 and close to the outer wall of the reel 6, and the strip head discharged from the strip outlet can be pressed down to be close to the outer wall of the reel 6, so that the strip head can be smoothly introduced into the strip entrance 7 again to achieve the winding of the strip head. In addition, preferably, the pressure plate 43 is rotatably connected to the boom frame 41, and an adjustment bolt for driving the pressure plate 43 to rotate relative to the boom frame 41 is provided on the boom frame 41. The rotation of the pressure plate 43 relative to the boom frame 41 can be controlled by the adjustment bolt. The adjustment action is generally after the swing of the boom frame 41 is completed, specifically, it is used to adjust the inclination angle of the pressure plate 43. The appropriate inclination angle of the pressure plate 43 can ensure that the strip head can be smoothly introduced and reduce the impact of the strip head on it. The rotation axis of the pressing plate 43 may be coaxial with the steering roller 53 , or the pressing plate 43 may be rotatably connected to the boom frame 41 via the steering roller 53 .

[0029] Further optimize the structure of the strip coiling device, such as Figure 1 and Figure 2The strip steel coiling device further comprises an auxiliary coiling mechanism 3, which comprises an auxiliary coiling roller 31 and a roller driving unit 33 arranged on the frame 2. The auxiliary coiling roller 31 is connected to the roller driving unit 33 so as to have a working position and a non-working position. In the working position, the auxiliary coiling roller 31 is close to the strip steel entrance 7 between the auxiliary coiling belt 51 and the reel 6, and cooperates with the reel 6 to form a strip steel bite pre-bending channel; in the non-working position, the auxiliary coiling roller 31 deviates from the auxiliary coiling belt 51. It can be understood that, in the working position, the above-mentioned auxiliary winding pressure roller 31 is in contact with the auxiliary winding belt 51; for the convenience of description, the starting contact point of the auxiliary winding belt 51 and the reel 6 at the above-mentioned strip steel inlet 7 is taken as the starting point of the wrap angle, and the ending contact point of the auxiliary winding belt 51 and the reel 6 at the above-mentioned strip steel outlet is taken as the end point of the wrap angle; in one embodiment, the above-mentioned auxiliary winding pressure roller 31 can be located above the starting point of the wrap angle, and it can apply pressure to the auxiliary winding belt 51 to make the auxiliary winding belt 51 closer to the reel 6; in another embodiment, the above-mentioned auxiliary winding pressure roller 31 can also be located at the starting point of the wrap angle or below the starting point of the wrap angle; and in other preferred schemes, a plurality of auxiliary winding pressure rollers 31 can be provided, and each auxiliary winding pressure roller 31 is arranged at intervals from top to bottom, and the position of each auxiliary winding pressure roller 31 can be arranged according to actual needs, so as to form a strip steel bite pre-bending channel between each auxiliary winding pressure roller 31 and the reel 6, so as to achieve the effect of gradually pre-bending the strip steel head, and at the same time avoid adverse effects on the strip steel quality.

[0030] The strip steel coiling device provided in this embodiment is provided with an auxiliary coiling mechanism 3, wherein the coiling pressure roller 31 can apply pressure to the strip steel entering between the coiling belt 51 and the reel 6, so as to achieve the effect of pre-bending the strip steel head, so that the strip steel head is better fitted on the reel 6 and is engaged by the coiling belt 51 and the reel 6, thereby improving the strip steel coiling effect and efficiency, avoiding the wear and scratch of the coiling belt 51 by the strip steel head, and can better solve the problem of high-strength thick plates being difficult to be coiled in the prior art. In addition, with the cooperation of the coiling pressure roller 31, the coiling tension can also be increased, so that the strip steel head is better wound on the reel 6.

[0031] like Figure 1 and Figure 2The auxiliary winding mechanism 3 further includes a winding roller frame 32, the winding roller 31 is mounted on the winding roller frame 32, and the winding roller frame 32 is connected to the roller driving unit 33. In the case where there are multiple winding rollers 31, the winding rollers 31 are arranged on the winding roller frame 32 from top to bottom to form a pre-bending roller row. It can be understood that the guide surface of the pre-bending roller row is an arc surface, that is, the front ends of the winding rollers 31 are located on the same arc surface. The curvature of the arc surface can be the same as the curvature of the reel 6, so that each auxiliary winding pressure roller 31 can press the auxiliary winding belt 51 at the corresponding position against the reel 6; or the curvature of the arc surface can be smaller than the curvature of the reel 6, for example, the top auxiliary winding pressure roller 31 is located above the starting point of the wrap angle, which can make the auxiliary winding belt 51 closer to the reel 6 but there is still a distance between it and the reel 6, while the other auxiliary winding pressure rollers 31 can press the auxiliary winding belt 51 at the corresponding position against the reel 6 (of course, the auxiliary winding belt 51 below the starting point of the wrap angle itself is in contact with the reel 6, but under the action of the auxiliary winding pressure roller 31, the clamping effect on the strip can be further increased, which can also increase the winding tension).

[0032] Further preferably, the roller shaft of the auxiliary winding pressure roller 31 is installed on the auxiliary winding roller frame 32 through an eccentric sleeve, and the gap value between the auxiliary winding pressure roller 31 and the reel 6 can be adjusted through the eccentric sleeve, which can adapt to strips of different thickness specifications on the one hand, and improve the pre-bending effect on the strip head on the other hand. Of course, the above gap value can also be adjusted under the action of the pressure roller drive unit 33, but the adjustment accuracy is limited, especially when multiple auxiliary winding pressure rollers 31 are installed on the auxiliary winding roller frame 32; and the above gap value can be further fine-tuned through the eccentric sleeve to ensure the adjustment accuracy.

[0033] Since the above-mentioned auxiliary winding pressure roller 31 acts on the strip steel entrance 7 between the auxiliary winding belt 51 and the reel 6, the auxiliary winding pressure roller 31 and the auxiliary winding roller frame 32 are preferably extended from the inside of the frame 2 to the vicinity of the reel 6. Furthermore, a guide channel is formed on the frame 2, and the auxiliary winding roller frame 32 is movably arranged in the guide channel, so that it can go deep into the storage slot or retreat into the frame 2. The above-mentioned pressure roller driving unit 33 can adopt conventional driving equipment such as a hydraulic cylinder, and its installation structure on the frame 2 and the connection structure between it and the auxiliary winding roller frame 32 are easy to design by those skilled in the art, and will not be described in detail here.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
