Description

Technical Field

[0001] The utility model relates to the technical field of winding and unwinding devices, in particular to a winding and unwinding device capable of controlling the tension of a coiled material. Background Art

[0002] The existing winding equipment generally includes a winding roller, which is connected to a motor that drives it to rotate. When winding, it is only necessary to wind the coiled material around the winding roller, and then the motor drives the winding roller to rotate, and the winding roller can rotate and rewind the coiled material by itself. Although the above-mentioned winding equipment can realize winding of the coiled material, since the distance between the winding roller of these winding equipment and the coil output of the coil production equipment is fixed, as the winding work proceeds, the diameter of the coil wound on the winding roller continues to increase, and then the distance between the force point of the subsequent winding coil and the coil output of the coil production equipment continues to increase. At this time, the tension of the coil in the winding process continues to increase, which makes the coil easily deformed due to excessive tension. In severe cases, the coil may also be torn.

[0003] In the prior art, in order to change the problem of tearing of the above-mentioned roll material due to the tension, multiple tensioning rollers are usually used. The tension of the roll material is adjusted by moving the position of the tensioning rollers, thereby changing the tension of the roll material during the winding and unwinding process. The setting of multiple tensioning rollers also requires staff to guide the roll material to move on the multiple tensioning rollers, which increases the staff's operating steps.

DETAILED DESCRIPTION

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] like Figure 1-4 The unwinding and rewinding device shown in the figure can control the tension of the coiled material, including a mounting seat 12, a unwinding and rewinding roller 15, a first drive motor 1, a diaphragm pressure sensor 16, a bearing mounting seat 17 and a pillow block tension sensor 25. The diaphragm pressure sensor 16 and the bearing mounting seat 17 are respectively mounted on both ends of the unwinding and rewinding roller 15. The movable end of the first drive motor 1 is connected to one end of the unwinding and rewinding roller 15. The two ends of the mounting seat 12 are respectively connected to the diaphragm pressure sensor 16 and the bearing mounting seat 17.

[0021] A rotating shaft 10 is provided above the mounting seat 12, one end of the rotating shaft 10 is connected to a stepper motor 4, a plurality of long tubes 5 are fixedly sleeved on the surface of the rotating shaft 10, a first movable block 13 is plugged into the bottom of the long tube 5, one end of the first movable block 13 is installed on the top of the mounting seat 12, the rotating shaft 10 is controlled by the stepper motor 4 to move in an arc, and then the rewinding and unwinding roller 15 is controlled to move in an arc synchronously, generating displacement during the arc movement, and then the position of the rewinding and unwinding roller 15 is adaptively adjusted according to the tension of the coil during the rewinding and unwinding process, thereby protecting the coil during the rewinding and unwinding process.

[0022] A distance adjustment mechanism is provided between the mounting seat 12 and the rotating shaft 10, and the distance adjustment mechanism includes a fixed block 11, a fixed block 11, and a ball screw 9 is passed through one end of the fixed block 11. The nut of the ball screw 9 is connected to the fixed block 11 through a movable limiting mechanism. A second drive motor 20 is installed on the side of the fixed block 11, and the movable end of the second drive motor 20 and the nut of the ball screw 9 are fixedly sleeved with a gear 7, and a gear chain 24 is sleeved between the two gears 7. In order to further adjust the tension of the coiled material on the rewinding and unwinding roller 15, it is only necessary to control the second drive motor 20 to control the two gears 7 and the gear chain 24 to drive the nut to rotate. During the rotation, the nut drives the screw of the ball screw 9 to move upward or downward, which is convenient for adjusting the distance between the rotating shaft 10 and the rewinding and unwinding roller 15, and then adjusting the radial size of the rewinding and unwinding roller 15 during the circular motion, so as to facilitate adaptive adjustment according to the size of the coiled material tension.

[0023] The nut fixing sleeve of the ball screw 9 is provided with a second movable block 23, and a slide groove 19 is opened along the arc side of the second movable block 23. A plurality of mounting blocks 18 are provided inside the slide groove 19, and one end of the plurality of mounting blocks 18 is installed on the top of the fixed block 11. During the force rotation of the nut of the ball screw 9, the nut drives the second movable block 23 to rotate on the plurality of mounting blocks 18 through the slide groove 19, thereby improving the stability of the nut during rotation.

[0024] The two ends of the mounting seat 12 are respectively connected to the connecting blocks 2, and one end of the two connecting blocks 2 is installed with an electric cylinder 3. The movable ends of the two electric cylinders 3 are respectively installed on the surface of the diaphragm pressure sensor 16 and the bearing mounting seat 17. As the thickness of the coiled material on the rewinding and unwinding roller 15 gradually decreases or increases, it is only necessary to control the two electric cylinders 3 to work synchronously, and the movable ends of the two electric cylinders 3 push or retract, so as to conveniently control the distance between the mounting seat 12 and the rewinding and unwinding roller 15.

[0025] A long hole 21 is opened on the side of the long tube 5, and a limit block 22 is installed at the other end of the first movable block 13. One end of the limit block 22 extends into the long hole 21. As the first movable block 13 and the long tube 5 slide, the first movable block 13 drives the limit block 22 to slide in the long hole 21, which facilitates the stability when adjusting the distance between the rotating shaft 10 and the rewinding roller 15.

[0026] Both ends of the rotating shaft 10 are provided with connecting plates 6 through bearing fixing sleeves, and a mounting plate 8 is installed between the top ends of the two connecting plates 6. The cooperation between the connecting plates 6 and the mounting plates 8 is used to fix the position of the rotating shaft 10 and facilitate the fixing of the position of the device.

[0027] A diaphragm pressure sensor 16 is installed at the bottom of the mounting base 12. The detection end of the diaphragm pressure sensor 16 corresponds to the surface position of the rewinding and unwinding roller 15. As the rewinding and unwinding roller 15 is in the process of rewinding and unwinding, the thickness of the roll material on its surface gradually decreases or increases. The diaphragm pressure sensor 16 is used to detect the thickness of the roll material, which is used to facilitate the detection of the pressure of the roll material of different thicknesses during the rewinding or unwinding process.

[0028] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
