[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] like Figure 1 , Figure 2 As shown, a coiling device for strip steel production of the utility model comprises a frame, a support frame, a coiling arm 3, a coiling roller, a reel 1, and a guide seat 5. The frame is fixedly arranged on the ground to support the device, and the reel 1 is rotatably connected to the frame. The rotatable connection structure between the reel 1 and the frame belongs to the conventional technology in the art, and does not belong to the innovation of the utility model. Therefore, the frame is not drawn in the attached drawings. The rotation of the reel 1 is driven by a motor, and the motor is connected to the shaft end of the reel 1 through a conveyor belt to drive the reel 1 to rotate, which belongs to the existing technology.

[0025] There are three auxiliary winding rollers, which are arranged at intervals along the outer circumference of the reel 1. The auxiliary winding arm 3 corresponds to the auxiliary winding roller one by one, and one end of the auxiliary winding arm 3 is used to be hinged with the frame, and the auxiliary winding roller is rotatably connected to the auxiliary winding arm 3. In this embodiment, the auxiliary winding roller is rotatably connected to the other end of the auxiliary winding arm 3. The rotation of the auxiliary winding roller is driven by a motor, and the motor is connected to the shaft end of the auxiliary winding roller through a conveyor belt to drive the auxiliary winding roller to rotate, which belongs to the prior art. The central axis of the auxiliary winding roller is parallel to the central axis of the reel 1, and the central axis of the reel 1 is horizontally arranged. Among them, the three auxiliary winding rollers are the first auxiliary winding roller 21, the second auxiliary winding roller 22, and the third auxiliary winding roller 23 in the conveying direction of the strip steel. The frame is provided with a cylinder 4 for driving the auxiliary winding roller to move. Specifically, the cylinder seat of the cylinder 4 is fixedly arranged on the frame, and the piston rod end of the cylinder 4 is hinged to the side of the auxiliary winding arm 3 close to the auxiliary winding roller. The cylinder 4 can drive the auxiliary winding roller to approach or move away from the reel 1. The conveying direction of the strip steel in this embodiment is Figure 1 , Figure 2 The directions indicated by the arrows in the text refer to the upstream and downstream of the conveying direction when the strip is wound on the reel 1 in the first circle.

[0026] The guide seat 5 is arranged corresponding to the auxiliary winding roller, that is, the number of the guide seats 5 is consistent with the number of the auxiliary winding rollers and corresponds one to one, and the guide seat 5 is arranged on the output side of the auxiliary winding roller. The guide seat 5 is fixedly connected to the auxiliary winding arm 3, and a slit 6 for guiding the strip to pass through is formed between the inner circumference of the guide seat 5 and the outer circumference of the reel 1. The width of the slit 6 gradually decreases along the conveying direction of the strip, that is, when the auxiliary winding roller contacts the reel 1, the distance between the inner circumference of the guide seat 5 and the outer circumference of the reel 1 is reduced. In this embodiment, the inner circumference of the guide seat 5 includes an arc-shaped inner arc surface 51 and a planar inner plane 52. In this embodiment, the ratio of the length of the inner plane 52 along the conveying direction of the strip to the arc length of the inner arc surface 51 is greater than 1 / 5 and less than 1 / 4, which can not only allow the strip to pass smoothly, but also enhance the tension of the strip. The circumferential surface where the inner arc surface 51 of the guide seat 5 is located is eccentrically arranged relative to the outer circumferential surface of the reel 1, that is, the central axis of the circumferential surface where the inner arc surface 51 of the guide seat 5 is located is parallel to the central axis of the reel 1, and the two central axes do not overlap. The inner plane 52 is located on the input side of the inner arc surface 51, and the extension surface of the inner plane 52 is tangent to the inner arc surface 51. The setting of the inner plane 52 facilitates the smooth entry of the strip. In addition, the numerical range of the distance between the side of the inner plane 52 opposite to the inner arc surface 51 and the outer circumferential surface of the reel 1 is 1mm-3mm, which does not affect the rotation of the auxiliary winding roller and can also make the head of the strip close to the outer circumferential side of the reel 1.

[0027] The angle between the first auxiliary winding roller 21 and the second auxiliary winding roller 22 is smaller than the angle between the second auxiliary winding roller 22 and the third auxiliary winding roller 23. The angle between the third auxiliary winding roller 23 and the first auxiliary winding roller 21 is larger than the angle between the second auxiliary winding roller 22 and the third auxiliary winding roller 23. When the first coil of strip steel is wound on the reel 1, the strip steel is looser when passing through the first auxiliary winding roller 21, and the distance between the two auxiliary winding rollers is small, so that the strip steel can be quickly compressed by the second auxiliary winding roller 22 after being rolled up by the first auxiliary winding roller 21, and a good compression force is maintained before passing through the third auxiliary winding roller. Compared with the case where the three auxiliary winding rollers are evenly distributed, the compression effect is better and the coiled strip steel is more uniform. In this embodiment, the angle between the first auxiliary winding roller 21 and the second auxiliary winding roller 22 is between 95° and 105°. In this embodiment, the angle between the first auxiliary winding roller 21 and the second auxiliary winding roller 22 is 100°, the angle between the second auxiliary winding roller 22 and the third auxiliary winding roller 23 is 125°, and the angle between the third auxiliary winding roller 23 and the first auxiliary winding roller 21 is 135°. The angle between the two auxiliary winding rollers mentioned herein refers to: when the auxiliary winding rollers are attached to the roll 1, the central axes of the three auxiliary winding rollers are on the same arc surface, and the center angle of the arc segment formed by the central axes of the two auxiliary winding rollers on the arc surface.

[0028] The use process of this embodiment is as follows: when the strip is output from the finishing mill, the distance between the auxiliary winding roller and the reel 1 is adjusted, and the distance allows 2-3 layers of steel plates to pass through as needed. Then, after the head of the strip approaches the reel 1, it passes through the first auxiliary winding roller 21, the second auxiliary winding roller 22, and the third auxiliary winding roller 23 in sequence. After passing through the auxiliary winding rollers and the slit 6, the tension of the strip is increased and it is rolled tightly to the outer peripheral side of the reel 1. The slit 6 can further increase the winding tension of the strip. After winding 2-3 turns, the strip can be tightly wound around the reel 1. At this time, the cylinder 4 can drive the auxiliary winding roller away from the reel 1.

[0029] It should be noted that when describing the positional relationship between the auxiliary winding roller, the reel and the guide seat, the description is made under the condition that the auxiliary winding roller is in contact with the outer circumference of the reel.

[0030] By means of the coiling device for strip steel production of the utility model, the coiling tightness of the strip steel on the reel 1 can be increased, and the problems of uneven coiling and loose coiling in the strip steel coiling process can be avoided.

[0031] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of 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.
