Therefore, these or other directional terms should not be interpreted as restrictive terms.
[0019] refer to Figures 1 to 4 , the embodiments of the present invention disclose: An aluminum strip tension control system comprises a frame 1, on which a first tension sensing device, a tension adjusting device, and a second tension sensing device are arranged for the aluminum strip to pass through in sequence; The first tension sensing device comprises an input frame 2 and a rotating frame 3 arranged at the input end of the frame 1, wherein the input frame (2) is arranged at one side of the tension adjusting device, the upper end of the rotating frame 3 is hinged to the input frame 2, and the lower end of the rotating frame 3 is rotatably provided with a roller 4; The input frame 2 is rotatably provided with a steering roller 5 , and the aluminum strip is input onto the steering roller 5 along a first direction, wherein the first direction is the conveying direction of the aluminum strip in this embodiment.
[0020] An introduction roller 6 is rotatably provided at the lower end of the rotating frame 3. As shown in the figure, the steering roller 5 is located above the introduction roller 6 and is located on the side closer to the tension adjustment device. The aluminum strip is input to the steering roller 5 along a first direction. After bypassing the steering roller 5, the aluminum strip is transported to the introduction roller 6 in a direction opposite to the first direction. Finally, the aluminum strip is transported to the tension adjustment device again in the first direction after bypassing the introduction roller 6.
[0021] It also includes a pressure sensor 7, which is horizontally arranged on the input frame 2 and the force-bearing end is facing the rotating frame 3, wherein the aluminum strip applies a force on the introduction roller 6 in the direction of the tension adjustment device when bypassing the introduction roller 6, so as to drive the lower end of the rotating frame 3 to flip in the direction of the tension adjustment device, and the rotating frame 3 presses against the force-bearing end of the pressure sensor 7 when flipping in the direction of the tension adjustment device, and also includes a controller, an information processor and a control power supply (not shown in the figure, which is an existing structure and is not described here), and the pressure sensor 7 is electrically connected to the controller, the information processor and the control power supply; in this embodiment, the tension of the aluminum strip can be known in real time by the aluminum strip applying a force on the introduction roller 6, and then the aluminum strip conveying speed can be adjusted in real time, so as to avoid deformation of the aluminum strip caused by excessive tension of the aluminum strip, and avoid deviation of the aluminum strip caused by insufficient tension of the aluminum strip, thereby improving the production quality of the aluminum strip in the production and molding process.
[0022] The specific working principle of the first tension sensing device is as follows: the aluminum strip passes around the steering roller 5 and the introduction roller 6 in turn, and is finally conveyed to the tension adjusting device. During the conveying process, when the aluminum strip passes around the introduction roller 6, it will exert a force on the introduction roller 6 toward the tension adjusting device. Since the upper end of the rotating frame 3 in this embodiment is hinged to the input frame 2, and the lower end can move relatively, that is, when subjected to force, the lower end of the rotating frame 3 can rotate a certain angle relative to the direction of the input frame 2, so that the rotating frame 3 and the aluminum strip maintain a relative balance state. When the rotating frame 3 rotates a certain angle, the rotating frame 3 will press against the force-bearing end of the pressure sensor 7. At this time, the pressure sensor 7 senses the pressure and transmits the information data to the information processor.
[0023] The input frame 2 is provided with a telescopic device, one end of which is hinged to the input frame 2 and the other end is hinged to the rotating frame 3; the telescopic device is a telescopic cylinder 8, which can be controlled to be telescopic, thereby driving the rotating frame 3 to reset.
[0024] The tension adjusting device comprises a plurality of fixed rollers 9 arranged side by side and a plurality of lifting rollers 10 arranged side by side. The aluminum strip is sequentially wound between the fixed rollers 9 and the lifting rollers 10. The spacing between the lifting rollers 10 and the fixed rollers 9 is adjustable so as to adjust the tension of the aluminum strip wound between the fixed rollers 9 and the lifting rollers 10. Specifically, in the present embodiment, the tension adjusting device further comprises a bed frame 101 (i.e., the frame 1 in the present embodiment) having a feed port on one side and a discharge port on the other side. A mounting frame 11 and a lifting frame 12 are arranged in the bed frame 101. Each of the fixed rollers 9 is rotatably arranged side by side on the mounting frame 11. Each of the lifting rollers 10 is rotatably arranged side by side on the lifting frame 12. The bed frame 101 A lifting device is provided on the bed frame 101, and the lifting device is used to drive the lifting frame 12 to move up and down, wherein the lifting device includes a driving rod 13 rotatably provided on the lifting frame 12, and a lifting chain 14 is provided on the bed frame 101 above the driving rod 13, the upper end of the lifting chain 14 is connected to the bed frame 101, and the lower end of the lifting chain 14 is connected to the driving rod 13, so that when the driving rod 13 rotates, it can drive the driving rod 13 and the lifting frame 12 to move up and down, and a driving motor 15 is provided at a middle position on the lifting frame 12, and the driving motor 15 is transmission-connected with the driving rod 13 to drive the driving rod 13 to rotate; specifically, the driving motor 15 drives the driving rod 13 to rotate, and the driving motor 15 drives the driving rod 13 to rotate. One end of the moving rod 13 is connected to the lifting chain 14. When the driving rod 13 rotates, the lifting chain 14 is wound around the driving rod 13, thereby driving the driving rod 13 and the lifting frame 12 to lift and lower. At this time, the aluminum strip is wound between the fixed roller 9 and the lifting roller 10. When the lifting frame 12 is lifted and lowered, the tension of the aluminum strip is also adjusted accordingly, which can avoid the problem of the aluminum strip being broken or stacked and bent due to tension when the input speed of the aluminum strip is inconsistent with the discharge (output) speed of the aluminum strip or the use speed of the aluminum strip is inconsistent with the discharge speed of the aluminum strip during production. In addition, during normal operation, the lifting frame 12 maintains a preset distance from the mounting frame 11, and the aluminum strip is wound around a plurality of fixed rollers 9 and a plurality of lifting rollers 1 in sequence. 0, so that the tension regulating device also has the function of storing the tape. During the period when the aluminum tape needs to be spliced, that is, when the input end of the tension regulating device no longer inputs the aluminum tape, the lifting frame 12 can be controlled to be gradually lowered, so that the output end of the tension regulating device can still output a certain length of aluminum tape at a certain speed. After the aluminum tape splicing is completed, the input end of the tension regulating device can re-input the aluminum tape to restore the overall conveying function. Therefore, the tension regulating device in this embodiment can not only be used to adjust the tension effect of the aluminum tape, but also can be used to store part of the aluminum tape, so that it can run normally for a certain time when the aluminum tape roll 25 is used up and the aluminum tape needs to be spliced, and the running time is enough for the aluminum tape to complete the splicing, so that the device can also convey the aluminum tape normally when the aluminum tape is spliced.
[0025] The second tension sensing device includes an installation box 16, a suspension tensioning mechanism arranged on the installation box 16, an active roller assembly arranged on one side of the suspension tensioning mechanism, and an output roller 17 arranged on one side of the suspension tensioning mechanism. The aluminum strip is sequentially wound between the active roller assembly and the output roller 17. The active roller assembly is used to introduce the aluminum strip output by the tension adjusting device, and the output roller 17 is used to output the aluminum strip. The suspension tensioning mechanism is used to control the aluminum strip to maintain a tensioned state; the active roller assembly includes an active roller 18 rotatably arranged on the installation box 16, and driven wheels 19 are arranged on both sides of the active roller 18; and the suspension tensioning mechanism includes a suspension roller 20 arranged between the active roller assembly and the output roller 17, and the suspension roller 20 can be raised and lowered on the installation box 16. The suspension roller 20 is used to press the aluminum strip under the action of gravity when the aluminum strip is transported from the active roller assembly to the output roller 17, so that the aluminum strip is in a tensioned state.
[0026] The suspension tensioning mechanism also includes a guide rod 21 arranged on a group of the installation boxes 16, a lifting seat 22 is arranged between the group of guide rods 21, and the suspension roller 20 is rotatably arranged on the lifting seat 22; at the same time, an electronic ruler 23 is arranged on one side of the guide rod 21 on the installation box 16; a sensing block is arranged on one side of the lifting seat 22, and the measuring end of the electronic ruler 23 faces the sensing block.
[0027] In this embodiment, the aluminum strip is input from the first tension sensing device, and output from the second tension sensing device, and an unwinder 24 is also provided in the direction of the aluminum strip input end (the unwinder 24 is used to place the aluminum strip roll 25 and control the aluminum strip roll 25 to output the aluminum strip at a uniform speed. The unwinder 24 is an existing device, which is not improved in this embodiment and will not be described in detail here), and a belt pressing mechanism 26 and a belt splicing mechanism are also provided between the unwinder 24 and the first tension sensing device (the belt pressing mechanism 26 is used to press the aluminum strip to limit the continued conveying of the aluminum strip, and the belt splicing mechanism is used to splice the aluminum strips. The belt pressing mechanism 26 and the belt splicing mechanism are both existing devices, which are not improved in this embodiment, and their detailed structures will not be described in detail here. At the same time, the belt splicing mechanism is not shown in the figure), when the aluminum strip roll 25 of the unwinder 24 is unwound, the belt pressing mechanism 26 will press the aluminum strip. At this time, the staff will reinstall the aluminum strip roll 25 and pull the aluminum strip to the belt splicing mechanism, so that the belt splicing mechanism can splice the new and old aluminum strips.
[0028] Working principle: In this embodiment, there are two working states, namely a normal working state and a belt connection state.
[0029] Working status: the unwinder 24 controls the aluminum strip coil 25 to output the aluminum strip at a uniform speed, the tape pressing mechanism 26 and the tape connecting mechanism are not started, and the aluminum strip passes through the tape pressing mechanism 26 and the tape connecting mechanism at a normal speed; at this time, it bypasses the steering roller 5 and the introduction roller 6 and is transported to the tension adjustment device. During the transportation process, the aluminum strip exerts a force on the introduction roller 6 toward the tension adjustment device, but because the input speed and output speed of the aluminum strip are equal at this time, the rotating frame 3 is subjected to less force, and the rotating frame 3 rotates a certain angle toward the input frame 2, that is, it maintains a relative balance with the aluminum strip; when the aluminum strip is input to the tension adjustment device, since there is a preset spacing between the lifting frame 12 and the mounting frame 11, the aluminum strip can have a certain total length (30m-60m) in the tension adjustment device, and then the aluminum strip is transported from the tension adjustment device to the active roller 18, and finally output by the output roller 17.
[0030] Tape splicing state: when the aluminum strip coil 25 of the unwinding machine 24 is about to be used up, the unwinding speed of the unwinding machine 24 is gradually reduced until it is 0, and the tape pressing mechanism 26 will press the aluminum strip. At this time, the staff will reinstall the aluminum strip coil 25 and pull the new aluminum strip to the tape splicing mechanism, so that the tape splicing mechanism can splice the new and old aluminum strips. When splicing, the aluminum strip input speed at the input end of the first tension sensing device is 0, while the aluminum strip at the output end of the second tension sensing device is still being output. At this time, the front and rear speeds of the aluminum strip are different. At the first tension sensing device, the aluminum strip is in a tensioned state. At this time, the aluminum strip exerts a force on the introduction roller 6 toward the tension adjusting device. At this time, the lower end of the rotating frame 3 rotates relative to the direction of the input frame 2, and during the rotation, it presses against and presses the force-bearing end of the pressure sensor 7. At this time, the pressure sensor 7 senses the pressure and transmits the information data to the information processor. At the same time, at the second tension sensing device, due to the slowdown in the aluminum strip conveying speed at the input end, the aluminum strip is in a tensioned state. In the tensioning state, during the conveying process, the suspension roller 20 located between the active roller 18 and the output roller 17 is lifted by the aluminum strip to a certain distance. At this time, the electronic ruler 23 arranged on one side of the guide rod 21 senses the lifting distance of the suspension roller 20, and the electronic ruler 23 is electrically connected to the pressure sensor 7, the controller, the information processor and the control power supply, and the sensed information data can be transmitted to the information processor; at this time, after the information processor processes the acquired data, the controller controls the driving motor 15 of the tension adjustment device to rotate, driving the lifting frame 12 to gradually descend. At this time, the distance between the lifting frame 12 and the mounting frame 11 is reduced, so that the aluminum strip stored between the lifting frame 12 and the mounting frame 11 can be normally output, thereby reducing the tension of the aluminum strip at the second tension sensing device, so that the suspension roller 20 is gradually lowered, and the output end of the tension adjustment device can still output a certain length of aluminum strip at a certain speed, so as to avoid insufficient aluminum strip delivery in subsequent production.
[0031] After the tape splicing mechanism completes the tape splicing, the tape pressing mechanism 26 no longer presses the aluminum tape, and the aluminum tape can be conveyed normally. At this time, the force exerted by the aluminum tape on the rotating frame 3 is reduced, and at the same time, the pressure sensed by the pressure sensor 7 is also reduced. The pressure sensor 7 senses the pressure and transmits the information data to the information processor. The controller controls the output end of the telescopic cylinder 8 of the first tension sensing device to extend a certain distance, thereby driving the rotating frame 3 to reset; at the same time, the controller controls the lifting frame 12 to gradually rise and reset, so that the tension adjustment device can store a certain length of aluminum tape again.
[0032] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation cases, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
