Description

Technical Field

[0001] The invention relates to the technical field of sheet material processing, in particular to a looper device of a color aluminum production line. Background Art

[0002] In the color aluminum production line, the loop tower is a relatively important equipment. It can temporarily store the color aluminum and unfold the color aluminum over a large area to dissipate heat or perform flaw detection. At the same time, during the roll changing process, the temporarily stored color aluminum can be released so that the production line does not need to be shut down. However, the release or storage of color aluminum by the existing loop tower is generally done manually, which is more labor-intensive. Therefore, a new type of loop device is needed to solve this problem. Summary of the invention

[0003] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or be understood by implementing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and other drawings of the description.

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a looper device for a color aluminum production line.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a looping device of a color aluminum production line, including a looping tower, the looping tower includes a bracket, the bracket is provided with a control device for controlling the looping tower to retract and release the color aluminum, the control device includes a fixed frame, a movable roller and two reversing rollers, the two reversing rollers are respectively arranged on both sides of the movable roller, the movable roller is slidably connected to the fixed frame through a sliding mechanism, the movable roller and the two reversing rollers are rotatably connected to the fixed frame, the fixed frame is provided with a counterweight mechanism for pulling the movable roller to move to one side, and the fixed frame is provided with a detector for detecting the displacement of the movable roller.

[0006] By adopting the above technical solution, the tension of the color aluminum and the pulling force of the counterweight mechanism on the movable roller are balanced under normal conditions. Therefore, the movable roller does not slide. When the color aluminum is no longer input into the looper, the tension of the color aluminum will increase because the processing equipment at the rear end will continue to transport the material forward. The reaction force of the tension will make the movable roller overcome the pulling force applied by the counterweight mechanism and slide through the sliding mechanism, thereby generating displacement and being detected by the detector. The detector can be a displacement sensor. At this time, the looper will release the color aluminum so that the tension is less than the pulling force of the counterweight mechanism, so that the movable roller is reset under the pull of the counterweight mechanism. After the reset, the looper stops working, and the looper is controlled in this way. When the tension decreases, the movable roller will be pulled by the counterweight mechanism and displaced, so that it is detected by the detector, and the looper is controlled to retract the color aluminum, so that the tension is greater than the pulling force of the counterweight mechanism, thereby driving the movable roller to reset, and the looper is automatically controlled in this way.

[0007] Preferably, the sliding mechanism is provided with two groups, and the two ends of the movable roller are respectively slidably connected to the fixed frame through the two groups of the sliding mechanism, and the two groups of the sliding mechanism each include a base, a slider and a guide rod, the guide rod is fixedly connected to the base, the slider is slidably connected to the guide rod, the slider is rotatably connected to the movable roller, and the counterweight mechanism is connected to the slider.

The present invention places the counterweight block in the counterweight cylinder and connects the counterweight cylinder to the movable roller through the pull rope 1. It can use the deadweight of the counterweight block to apply a constant pulling force to the movable roller, so that the colored aluminum is always subjected to a constant tension force, so that it can quickly react and produce displacement when the tension changes. The guide cylinder can be used to guide the counterweight cylinder to slide, so as to prevent the counterweight cylinder from swinging and causing danger.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0034] like Figure 1-4 As shown, a looping device of a color aluminum production line includes a looping tower 1, the looping tower 1 includes a bracket, the bracket is provided with a control device for controlling the looping tower 1 to retract and release the color aluminum, the control device includes a fixed frame 2, a movable roller 3 and two reversing rollers 4, the two reversing rollers 4 are respectively arranged on both sides of the movable roller 3, the movable roller 3 is slidably connected to the fixed frame 2 through a sliding mechanism, the movable roller 3 and the two reversing rollers 4 are both rotatably connected to the fixed frame 2, the fixed frame 2 is provided with a counterweight mechanism for pulling the movable roller 3 to move to one side, and the fixed frame 2 is provided with a detector for detecting the displacement of the movable roller 3.

[0035] By adopting the above technical solution, the tension of the color aluminum and the pulling force of the counterweight mechanism on the movable roller 3 are balanced under normal conditions. Therefore, the movable roller 3 does not slide. When the color aluminum is no longer input into the looper tower 1, the tension of the color aluminum will increase because the processing equipment at the rear end will continue to transport the material forward. The reaction force of the tension will cause the movable roller 3 to overcome the pulling force applied by the counterweight mechanism and slide through the sliding mechanism, thereby generating displacement and being detected by the detector. The detector can be a displacement sensor. At this time, the looper tower 1 will release the color aluminum so that the tension is less than the pulling force of the counterweight mechanism, so that the movable roller 3 is reset under the pull of the counterweight mechanism. After the reset, the looper tower 1 stops working, and the looper tower 1 is controlled back and forth. When the tension decreases, the movable roller 3 will be pulled by the counterweight mechanism and displaced, so that it is detected by the detector, and the looper tower 1 is controlled to retract the color aluminum, so that the tension is greater than the pulling force of the counterweight mechanism, thereby driving the movable roller 3 to reset, and the looper tower 1 is automatically controlled in this way.

[0036] Two groups of sliding mechanisms are provided, and the two ends of the movable roller 3 are respectively slidably connected to the fixed frame 2 through the two groups of sliding mechanisms.

The guide rod 7 is fixedly connected to the base 5, the slider 6 is slidably connected to the guide rod 7, the slider 6 is rotatably connected to the movable roller 3, and the counterweight mechanism is connected to the slider 6. By using the mutual cooperation of the guide rod 7 and the slider 6, the two ends of the movable roller 3 can be stably supported and can slide stably, ensuring that the two ends of the movable roller 3 will not deviate from each other.

[0037] The counterweight mechanism includes a drawstring 8, a counterweight cylinder 9, a counterweight block 10 and a guide cylinder 11. The guide cylinder 11 is fixedly connected to the fixed frame 2. The counterweight cylinder 9 is sleeved on the outside of the guide cylinder 11, and the counterweight cylinder 9 is slidably connected to the guide cylinder 11. The counterweight block 10 is arranged in the counterweight cylinder 9. One end of the drawstring 8 is fixedly connected to the bottom of the counterweight cylinder 9, and the other end of the drawstring 8 is connected to the movable roller 3. By placing the counterweight block 10 in the counterweight cylinder 9 and connecting the counterweight cylinder 9 to the movable roller 3 through the drawstring 8, the deadweight of the counterweight block 10 can be used to apply a constant pulling force to the movable roller 3, so that the colored aluminum can always be subjected to a constant tension force, so that when the tension changes, it can quickly react and produce displacement. The guide cylinder 11 can be used to guide the counterweight cylinder 9 to slide, so as to prevent the counterweight cylinder 9 from swinging and causing danger.

[0038] There are several counterweight blocks 10, and the fixing frame 2 is provided with an adjusting mechanism for adjusting the number of counterweight blocks 10 in the counterweight cylinder 9.

The storage box 12 is used to place excess configuration blocks. When it is necessary to increase weight, the counterweight 10 is pushed into the counterweight cylinder 9 one by one through the pushing mechanism. When it is necessary to reduce weight, all configuration blocks are first pushed to the top of the guide cylinder 11 through the ejection mechanism, and then the uppermost counterweight 10 is pushed into the storage box 12 through the pushing mechanism. Every time a counterweight 10 is pushed in, the ejection mechanism drives all the counterweights 10 to rise a certain distance.

[0040] Each pushing mechanism includes a cylinder 13 and a pusher 14, the pusher 14 is slidably connected to the storage box 12, the pusher 14 abuts against the counterweight 10, the cylinder 13 is fixedly connected to the fixing frame 2, and the output rod of the cylinder 13 is in transmission connection with the pusher 14. The pusher 14 is driven to slide by the extension and contraction of the cylinder 13, so that the counterweight 10 can be pushed into the counterweight cylinder 9, and the pusher 14 can be driven to slide backward to make room before the pushing mechanism pushes the counterweight 10 into the storage box 12.

[0041] The ejection mechanism includes a top plate 16 and a second cylinder 15. The top plate 16 is arranged in the counterweight barrel 9. The top plate 16 abuts against the bottom of the counterweight block 10 located at the bottom of the counterweight barrel 9. The second cylinder 15 is fixedly connected to the counterweight barrel 9, and the output rod of the second cylinder 15 is in transmission connection with the top plate 16.

The push piece 17 is aligned with the entrance of the storage box 12. The cylinder 3 18 is fixedly connected to the fixed frame 2. The output rod of the cylinder 3 18 is transmission-connected to the push piece 17. The push piece 17 is driven to slide back and forth by the telescopic movement of the cylinder 3 18. Each time the reciprocating slide is performed, a counterweight 10 can be pushed into the storage box 12.

[0043] The fixed frame 2 is provided with a balancing mechanism for balancing the self-weight of the counterweight cylinder 9, the second cylinder 15 and the top plate 16. The balancing mechanism includes a second pull rope 19 and a balancing block 20. The two ends of the second pull rope 19 are respectively connected to the movable roller 3 and the balancing block 20.
