However, when a relatively thin, narrow or soft metal strip is subjected to a relatively large amount of tension, the metal strip is easily broken or deformed, resulting in non-uniform thickness or width of the metal strip, which causes quality problems in subsequent production.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts will fall within the protection scope of the present invention.

The invention discloses a micro-tension metal belt 4 rewinding machine which comprises an unwinding device 1, a winding device 2 and a tension adjusting device 3, wherein the unwinding device is arranged on the winding device; unwinding device 1 is used for the level to place the metal strip roll, and coiling mechanism 2 is used for carrying out vertical rolling to metal band 4 that unwinding device 1 spreads out, and tension adjusting device 3 is used for adjusting coiling mechanism 2 and carries out the tension of rolling to metal band 4, and the concrete effect is seen in figure 1.

In this application, the metal band that will need to carry out the bundling is rolled up and is placed on unwinding device 1 horizontally, and the tip winding of metal band book is on coiling mechanism 2, through unwinding device 1 rotation with 4 outgoing of rolling up of metal band layer by layer, coiling mechanism 2 is rotatory to be coiled metal band 4 layer by layer, forms new metal band book. Because this rewinder's coiling mechanism 2 is vertical carries out the rolling to strap 4 to the edge and the coiling mechanism 2 friction of strap 4 when preventing the rolling lead to strap 4 turn-up, influence its use.

In the practical production, the metal belt 4 produced by the manufacturer is usually wound into a disc shape, but in the actual use process, the size of the metal belt coil produced by the manufacturer does not necessarily meet the actual use requirement, so that the metal belt coil produced by the manufacturer is required to be separated, and the requirement of the actual production can be met. When carrying out the bundling to the metal coil of strip, if the compactness that the rewinder coiled to strap 4 is not enough, can appear collapsing after the diameter of strap coil of strip reaches certain numerical value, lead to the unable coiling of strap 4 to influence follow-up use. In order to achieve a tight winding of the metal strip 4, it is therefore usual in the prior art to apply a certain counter-tension to the metal strip 4 during the unwinding. However, when a relatively thin, narrow or soft metal strip 4 is subjected to a relatively large tensile force, the metal strip 4 is easily broken or deformed, and the thickness or width of the metal strip 4 is not uniform, thereby causing quality problems in subsequent production.

In the application, the rewinding machine is further provided with a tension adjusting device 3, on one hand, the metal strip can be tightly wound on the winding device by applying tension to the metal strip 4 in the process that the unwinding device 1 rotates to unwind the metal strip coil layer by layer and the winding device 2 rotates to wind the metal strip 4 layer by layer, so that the metal strip is prevented from collapsing after the diameter of the metal strip coil rewound by the rewinding machine reaches a certain value, the metal strip 4 cannot be wound into a coil, and subsequent use is influenced; on the other hand, the tension adjusting device 3 can adjust the tension applied to the metal strip 4 according to different metal strips 4, so that the metal strip 4 is prevented from being broken or deformed due to excessive tension applied to the metal strip 4 during rewinding.

In this application, the unwinding device 1 includes a first support frame 11, an unwinding reel 12 horizontally rotating on the first support frame 11 for placing the metal strip coil, and an unwinding motor 13 disposed on the first support frame 11 for driving the unwinding reel 12 to horizontally rotate, wherein an air-expansion shaft 14 penetrating through the center of the metal strip coil and used for fixing the metal strip coil on the unwinding reel 12 is disposed on the unwinding reel 12, and the specific effect is shown in fig. 2. Unwinding device 1 includes first support frame 11, unreels a set 12 and unreels motor 13, unreels set 12 and unreels motor 13 and sets up on first support frame 11, through first support frame 11 and ground butt, supports unreeling set 12 and unreeling motor 13, unreels set 12 and horizontal rotation on first support frame 11, unreels motor 13 drive and unreels set 12 and horizontal rotation on first support frame 11.

The unwinding disc 12 is provided with an air-expansion shaft 14, the air-expansion shaft 14 penetrates through the center of the metal strip coil and then is opened, the metal strip coil to be unwound is fixed on the unwinding disc 12, the metal strip coil horizontally rotates on the first support frame 11 along with the unwinding disc 12, and therefore the metal strip coil is gradually unwound by the unwinding disc 12. The reason why the air expansion shaft 14 is arranged on the unwinding disc 12 to fix the metal strip coil is to prevent the metal strip coil from rotating along with the unwinding disc 12 due to friction between the edge of the metal strip coil and the surface of the unwinding disc 12, which causes the metal strip 4 to curl and affects subsequent use, rather than to make the metal strip coil rotate along with the unwinding disc 12 due to friction between the unwinding disc 12 and the metal strip coil.

In the present embodiment, the winding device 2 includes a second support frame 21, a winding disc 22 vertically rotating on the second support frame 21 for winding the metal strip 4, and a winding motor 23 for driving the winding disc 22 to vertically rotate, as shown in fig. 3. The winding device 2 comprises a second support frame 21, a winding disc 22 and a winding motor 23, wherein the winding disc 22 and the winding motor 23 are arranged on the second support frame 21 and are abutted against the ground through the second support frame 21 to support the winding disc 22 and the winding motor 23. The winding disc 22 vertically rotates on the second support frame 21, and it is contemplated that the winding disc 22 is supported on the second support frame 21 through a rotating shaft, and the winding motor 23 drives the rotating shaft to rotate on the second support frame 21, so as to drive the winding disc 22 to rotate, and vertically wind the metal strip 4 delivered from the unwinding disc 12 on the winding disc 22.

There are three conditions between the speed of the winding motor 23 driving the winding disc 22 to rotate vertically on the second support frame 21 and the speed of the unwinding motor 13 driving the unwinding disc 12 to rotate horizontally on the first support frame 11. The first situation is that the rotation speed of the take-up reel 22 is lower than that of the unwinding reel 12, which results in no tension at all between the metal strip 4 transferred between the unwinding reel 12 and the take-up reel 22, and on the one hand, may cause the metal strip 4 to drag against the ground, causing damage to the metal strip 4; on the other hand, it may result in the metal strip 4 not being tightly wound on the take-up reel 22. In the second case, the rotation speed of the winding disc 22 is equal to the rotation speed of the unwinding disc 12, the metal strip 4 coming out from the unwinding disc 12 is just wound by the unwinding disc 12, and the tension adjusting device 3 applies tension to the metal strip 4, so that the metal strip 4 is tightly wound on the winding disc 22. The third situation is that the rotation speed of the winding reel 22 is higher than that of the unwinding reel 12, and the metal strip 4 is tightly wound around the winding reel 22 with tension between the metal strip 4 transferred between the unwinding reel 12 and the winding reel 22, but if the rotation speed of the winding reel 22 is much higher than that of the unwinding reel 12, the tension on the metal strip 4 is too high, and the metal strip 4 is broken or deformed. Therefore, in the present application, it is preferable that the winding motor 23 drives the winding reel 22 to rotate vertically on the second supporting frame 21 at a speed equal to or slightly higher than the speed at which the unwinding motor 13 drives the unwinding reel 12 to rotate horizontally on the first supporting frame 11.

In this embodiment, the tension adjusting device 3 includes a pressing frame 31 rotatably connected to the second supporting frame 21, and a pressure cylinder 32 fixed on the second supporting frame 21 for driving the pressing frame 31 to rotate on the second supporting frame 21, wherein when the pressure cylinder 32 drives the pressing frame 31 to rotate on the second supporting frame 21, the pressing frame 31 presses or releases the roll of the metal strip 4 on the winding disc 22, and the specific effect is shown in fig. 3. The tension adjusting device 3 comprises a pressing frame 31 and a pressure cylinder 32, the pressing frame 31 is rotatably connected on the second support frame 21, the cylinder end of the pressure cylinder 32 is fixed on the second support frame 21, the air rod end is fixedly connected with the pressing frame 31, and when the air rod of the pressure cylinder 32 extends and retracts from the cylinder, the pressing frame 31 is driven to rotate on the second support frame 21. When the metal strip 4 is wound on the winding disc 22 after the unwinding disc 12 takes out the metal strip 4 layer by layer, the air rod of the pressure air cylinder 32 contracts to drive the pressing frame 31 to rotate on the second support frame 21, so that the pressing frame 31 is abutted against the metal strip 4 which is just wound on the winding disc 22, and the metal strip 4 is tightly wound on the winding disc 22.

In this embodiment, the tension adjusting device 3 further includes a plurality of winding columns 311 disposed on the pressing frame 31, and after the metal strip 4 delivered from the unwinding device 1 sequentially passes through the plurality of winding columns 311, the winding device 2 winds up the metal strip 4, with the specific effects as shown in fig. 1 and fig. 4. The plurality of winding columns 311 are provided on the pressing frame 31, and after the unwinding device 1 discharges the metal tape 4, the metal tape 4 is sequentially wound around the plurality of winding columns 311 and is finally wound around the winding reel 22. On one hand, in order to prevent the distance between the winding disc 22 and the unwinding disc 12 from being too far, the metal belt 4 drags the ground under the action of self gravity and affects the winding efficiency of the winding disc 22, the metal belt 4 is wound on the plurality of winding columns 311, so that the winding columns 311 can well support the metal belt 4; on the other hand, the metal strip 4 is wound around the plurality of winding columns 311 on the pressing frame 31 and then is delivered out, and is wound around the winding reel 22, so that the pressing frame 31 can have a better effect of pressing the metal strip 4 after abutting against the metal strip 4.

In this embodiment, the tension adjusting device 3 further includes a pressing column 312 disposed on the pressing frame 31, when the pressing frame 31 presses the metal tape 4 roll on the winding tray 22, the pressing column 312 is attached to the outer surface of the metal tape roll, and a pressure sensor 313 is disposed between the pressing column 312 and the pressing frame 31 for detecting the pressure of the pressing column 312 on the metal tape 4 roll, with the specific effects as shown in fig. 1 and fig. 4. The pressing frame 31 is further provided with a pressing column 312, when the pressure cylinder 32 contracts, the pressing frame 31 is driven to rotate on the second supporting frame 21, so that the pressing column 312 on the pressing frame 31 is attached to the outer surface of the metal belt 4 on the winding disc 22 and presses the metal belt. The reason why the pressing bar 312 is arranged on the pressing frame 31 to contact the metal strip 4 is that the outer surface of the pressing bar 312 contacting the metal strip 4 is arc-shaped and is similar to the shape of the metal strip 4 wound on the winding disc 22, so that when the pressing frame 31 presses the metal strip 4, the edge on the pressing frame 31 scratches the metal strip 4, which affects the subsequent use of the metal strip.

A pressure sensor 313 is arranged between the pressing column 312 and the pressing frame 31, when the pressing column 312 presses the metal belt 4, the pressing column 312 applies acting force to the metal belt 4, meanwhile, the metal belt 4 also applies reaction force to the pressing column 312, the acting force applied to the pressing column 312 by the metal belt 4 is transmitted to the pressure sensor 313, the acting force applied to the metal belt 4 by the pressing column 312 is equal to the reaction force applied to the pressing column 312 by the metal belt 4, so that the pressure sensor 313 can sense the pressing force applied to the metal belt 4 by the pressing column 312, an electric signal is transmitted to a control system through the pressure sensor 313, and the control system controls the air rod shrinkage of the pressure cylinder 32, so that the tension adjusting device 3 adjusts the tension when the metal belt 4 is wound.

In the present embodiment, a tension sensor 314 is disposed between the plurality of winding posts 311 and the pressing frame 31, and the specific effect is shown in fig. 4. In order to wind the metal strip 4 delivered from the unwinding reel 12 tightly on the winding reel 22, it is difficult to achieve the effect of the force applied to the metal strip 4 only by the pressing rod 312, and it is necessary to wind the metal strip 4 delivered from the unwinding reel 12 on the winding reel 22 with tension between the metal strip 4, which requires controlling the speed of the winding motor 23 driving the winding reel 22 to rotate vertically on the second support frame 21 and the speed of the unwinding motor 13 driving the unwinding reel 12 to rotate horizontally on the first support frame 11. Therefore, a tension sensor 314 is provided between the plurality of winding posts 311 and the pressing frame 31, the metal tape 4 delivered from the unwinding reel 12 is wound around the winding reel 22 after being sequentially wound around the plurality of winding posts 311, and the tension between the metal tapes 4 is applied to the winding posts 311 and transmitted to the tension sensor 314 through the winding posts 311.

In the application, the speed of the winding motor 23 driving the winding disc 22 to vertically rotate on the second support frame 21 is fixed, and when the electric signal transmitted by the tension sensor 314 reflects that the tension on the metal strip 4 is small, the control system controls the unwinding motor 13 to reduce the speed of the unwinding disc 12 horizontally rotating on the first support frame 11; when the electric signal transmitted by the tension sensor 314 reflects that the tension on the metal strip 4 is too large, the control system controls the unwinding motor 13 to increase the speed of the unwinding disc 12 horizontally rotating on the first support frame 11. Obviously, in practical applications, the speed at which the winding motor 23 drives the winding disc 22 to vertically rotate on the second support frame 21 may not be fixed, and the control system controls the speed ratio between the speed at which the winding motor 23 drives the winding disc 22 and the speed at which the unwinding motor 13 drives the unwinding disc 12 to adjust the tension between the metal strips 4, which also belongs to the protection scope of the present application.

In this embodiment, a deviation rectifying device 5 is further included for rectifying deviation of the metal strip 4 coming out from the unwinding device 1, and the specific effect is shown in fig. 1. Since the unwinding reel 12 horizontally discharges the metal strip coil to be unwound, the winding reel 22 vertically winds the metal strip 4 unwound from the unwinding reel 12, and the horizontal position of the winding reel 22 on the second support frame 21 is fixed, the unwinding reel 12 discharges the metal strip 4 layer by layer, and the metal strip 4 may be shifted in the horizontal direction due to vibration and the like in the process of transmission, so that the discharged metal strip 4 cannot be accurately wound on the winding reel 22, in the present application, the deviation correcting device 5 is further provided for adjusting the horizontal unwinding direction of the metal strip 4, so that the metal strip 4 is accurately wound on the winding reel 22.

In this embodiment, the deviation rectifying device 5 includes a plurality of deviation rectifying columns 51 disposed on the first support frame 11 for winding the metal tape 4, a moving platform 52 disposed on the first support frame 11, and a moving column 53 disposed on the moving platform 52, and the metal tape 4 sent from the unwinding disc 12 sequentially passes through the plurality of deviation rectifying columns 51 and then is wound on the moving column 53, with the specific effects as shown in fig. 1 and fig. 2. The deviation correcting device 5 comprises a plurality of deviation correcting columns 51, a moving platform 52 and a moving column 53, wherein the deviation correcting columns 51 are arranged on the first support frame 11, the moving platform 52 is arranged at the tail ends of the deviation correcting columns 51 on the first support frame 11, namely, at one end far away from the reel releasing disc 12, and the moving column 53 is arranged on the moving platform 52.

After the unwinding reel 12 winds the metal strip 4 to be unwound layer by layer, the metal strip 4 is sequentially wound on the plurality of deviation rectifying columns 51, then wound on the moving columns 53 at the tail ends of the plurality of deviation rectifying columns 51, and finally wound on the winding reel 22. When the metal strip 4 is deviated in the horizontal direction in the transferring process, the moving platform 52 is adjusted to enable the moving column 53 to horizontally move on the moving platform 52, so that the position of the moving column 53 in the horizontal direction on the first support frame 11 is adjusted, the horizontal outgoing direction of the metal strip 4 wound on the moving column 53 is driven to be changed, and the metal strip 4 is accurately wound on the winding disc 22.

In this embodiment, the deviation rectifying device 5 further includes two oppositely disposed limiting frames 54 and a deviation rectifying sensor disposed on the limiting frames 54, a channel for the metal belt 4 to pass through is disposed between the two limiting frames 54, and the two limiting frames 54 are disposed on the second supporting frame 21, which has the specific effects shown in fig. 1 and fig. 3. Two oppositely arranged limiting frames 54 are arranged on the second supporting frame 21, a channel for the metal belt 4 to pass through is formed between the limiting frames 54, in order to prevent the metal belt 4 from deviating in the horizontal direction, and therefore the metal belt 4 is abutted against two side walls of the channel formed by the two limiting frames 54 to cause the metal belt 4 to be curled, and the subsequent use of the metal belt is influenced, and the width of the channel formed by the two oppositely arranged limiting frames 54 is larger than the width of the metal belt 4.

The two side walls of the channel formed by the two limit frames 54 are provided with deviation rectifying sensors, when the metal belt 4 deviates in the horizontal direction, the deviation rectifying sensors are close to one side wall, the deviation rectifying sensors sense the deviation of the metal belt 4, and the direction of the deviation of the metal belt 4 can be detected according to the side wall of the channel where the deviation rectifying sensors are located, so that the deviation rectifying sensors transmit electric signals to the control system, the control system controls the moving platform 52 to drive the moving column 53 to move in the horizontal direction according to the deviation direction of the metal belt 4, and further the horizontal transmission direction of the metal belt 4 is adjusted.

In this embodiment, a meter sensor 6 may also be disposed on the second support frame 21, for a specific effect, see fig. 1 and fig. 3. When the metal strip 4 is delivered from the unreeling disc 12 and is coiled on the reeling disc 22 after passing through the meter sensor 6, the meter sensor 6 can detect the number of meters of the metal strip 4 coiled on the reeling disc 22, on one hand, when the metal strip coil is uncoiled through the rewinder, the number of meters of the separated metal strip 4 can be clearly known, and the meter sensor 6 provides a signal for finishing the rewinding, so that a worker can conveniently stop the rewinder in time, and the metal strip 4 uncoiled on the reeling disc 22 meets the requirement of actual use; on the other hand, when the metal belt 4 breaks in the rewinding process, the meter sensor 6 does not detect that the metal belt 4 passes through, and provides a belt breaking signal for workers, so that the rewinding machine is prevented from idling, and the rewinding efficiency is prevented from being influenced.
