DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-4 The utility model provides a multi-roller combined unwinding device, comprising:

[0025] The first fixed plate 101 is used to install the unwinding roller mechanism 200, the swingable roller mechanism 300, the first limiting roller mechanism 400 and the second limiting roller mechanism 500. The positions of the roller mechanisms on the first fixed plate 101 are designed according to certain proportional parameters so that the performance requirements can be met. The first fixed plate 101 can be fixed on other shelves or the ground;

[0026] A second fixed plate 601 is used to place the leveling roller mechanism 600. The second fixed plate 601 can be fixed on a shelf or the ground of a set working surface;

[0027] The unwinding roller mechanism 200 is installed at the center of the first fixed plate 101, and is composed of an unwinding roller 201, a tightening ring 202, a positioning ring 203, a driving motor 204 and a moving rod 205. The unwinding roller 201 can be rotated to open or collect the coil. The unwinding roller 201 of the unwinding roller mechanism 200 is composed of an axis core and an outer cylinder. One end of the axis core is connected to the axis of the driving motor 204 through a keyway and a bearing. The driving motor 204 is fixed on the first fixed plate 101, and the other end of the axis core is connected to the moving rod 205 through a thread. The moving rod 205 is provided with a step. The rotating moving rod 205 can horizontally pull the outer cylinder of the unwinding roller 201. The outer cylinder of the unwinding roller 201 is installed with a positioning ring 203 and a tightening ring 202, which can position and tighten the coil 102 to prevent the coil from spinning. The driving motor 204 is a driving and braking device for the unwinding roller 201.

[0028] The swingable roller mechanism 300 is installed on the first fixed plate 101 and is located on the left side of the unwinding roller mechanism 200. It is composed of a swingable rod 301, a swing roller 302, a detection sensor 303, a swing rod fixing seat 304, a spring 306 and a spring seat 305. The swingable rod 301 is provided with four through holes. The swing roller 302 is placed in the two lower through holes. The two upper through holes, the relatively inner through holes are connected to the swing rod fixing seat 304. The swingable rod 301 can rotate around the swing rod fixing seat 304. The relatively outer through holes are connected to one end of the spring 306. The other end of the spring 306 is fixed to the first fixed plate 101 through the spring seat 305. The detection sensor 303 is placed on the arc path of the swingable rod 301 and is fixed to the first fixed plate 101.

[0029] The switch of the driving motor 204 is controlled by the swingable roller mechanism 300, and the signal of the detection sensor 303 is connected to the driving motor 204. When the swingable rod 301 rotates around the swing rod fixing seat 304, it transmits a start signal when leaving the detection range of the detection sensor 303, and transmits a stop signal when entering the range of the detection sensor 30. Considering that a single-layer coil is easily pulled and deformed, the double swing rollers 302 are set to improve the load capacity of the coil 102 for the rollers. Considering that shutdown and power failure and excessively fast coiling speed may cause the swing roller 302 to rotate at a high angle and rotate quickly, a spring 306 and a spring seat 305 are set to constrain the position of the swingable rod roller mechanism 300 to a certain extent.

[0030] The first limiting roller mechanism 400 includes three first limiting rollers arranged in parallel, and each first limiting roller is mounted on the first fixing plate 101 via a fixing seat.

[0031] The second limiting roller mechanism 500 includes two second limiting rollers arranged in parallel, and each second limiting roller is mounted on the first fixing plate 101 via a fixing seat.

[0032] The leveling roller mechanism 600 includes a third limit roller 602, a squeeze roller 603 and an adjustment roller 604 which are arranged in parallel and in a triangular shape, wherein the squeeze roller 603 is located on the upper side, and the third limit roller 602 and the adjustment roller 604 are located on the lower side, and the ends of the third limit roller 602, the squeeze roller 603 and the adjustment roller 604 are respectively fixedly mounted on the second fixing plates 601 on both sides, and the second fixing plates 601 on both sides are connected by a connecting beam 605. An extrusion cylinder 607 is provided above 605, and an extrusion bar 606 is installed at the end of the extrusion cylinder 607. The extrusion cylinder 607 is driven to push the extrusion bar 606 onto the extrusion roller 603; two countersunk holes are provided on the second fixed plate 601, which are respectively used to fix the third limiting roller 602 and the extrusion roller 603, and a long hole is provided on the second fixed plate 601 for placing the adjusting roller 604. The adjusting roller 604 can adjust the horizontal position up and down between the two fixed plates through the long hole.

[0033] During operation, the coil is wound through the unwinding roller mechanism 200 into the swingable roller mechanism 300, and then goes around the first limiting roller mechanism 400 and the second limiting roller mechanism 500 to enter the leveling roller mechanism 600. In the leveling roller mechanism 600, the coil goes around the bottom of the third limiting roller 602, the top of the squeezing roller 603 and the bottom of the adjusting roller 604 to enter the working surface. The leveling roller mechanism 600 is fixed at the required height of the coil working surface by two second fixed plates 601. The squeezing bar 606 can be pushed by the squeezing cylinder 607 and placed on the squeezing roller 603 to smooth out the wrinkles of the coil 102 that cannot be tensioned. At the same time, the coil 102 can be pressed when the work is suspended to maintain the current state of the coil 102. The long strip hole on the lower left side of the second fixed plate 601 is used to install the leveling roller 604, which can keep the coil 102 flush with the working surface by sliding up and down to prevent the coil 102 from tilting.
