Description

Technical Field

[0001] This application relates to the field of tension testing technology, and more specifically, to a tension testing device for aluminum-plastic composite belts. Background Technology

[0002] Aluminum-plastic composite tape is made by coating ethylene-methacrylic acid copolymer resin on both sides A and B of an aluminum base tape to achieve a certain degree of adhesion. The color is natural or blue.

[0003] Currently, in the production of aluminum-plastic composite strips, precise tension control is crucial to ensuring product quality. Therefore, tension testing equipment is needed to perform tension testing. However, existing tension testing equipment typically clamps and fixes the two ends of the aluminum-plastic composite strip by pressing down with a pressure plate. Due to the thin sheet design of the aluminum-plastic composite strip, it is prone to loosening during the testing process due to tension, thus affecting the accuracy of tension testing.

[0004] To address the aforementioned issues, this application provides an aluminum-plastic composite belt tension testing device. Utility Model Content

[0005] This application provides an aluminum-plastic composite belt tension testing device, comprising a main frame, with U-shaped frames distributed on both sides inside the main frame. A left roller is fixedly installed on the inner wall of the upper end of the left U-shaped frame, and a right roller is fixedly installed on the inner wall of the upper end of the right U-shaped frame. Extending protrusions are distributed at the middle of the bottom inner walls of both U-shaped frames, and a bidirectional cylinder is fixedly connected between the two bottom extending protrusions. A groove is embedded in the middle outer wall of the left roller, and a rotating cylinder is rotatably sleeved on one side of the groove. One end face of the rotating cylinder is uniformly circumferentially open. The device has multiple insertion holes. A movable ring is slidably fitted onto the other side of the groove. Multiple insertion rods are uniformly fixedly connected to one end face of the movable ring, and the insertion rods are respectively inserted into the multiple insertion holes in a one-to-one correspondence. Four springs are uniformly fixedly installed at the connection between the other end face of the movable ring and the inner wall of one side of the groove. Multiple four lugs are uniformly fixedly connected to the outer wall of the movable ring. A limit expansion joint is distributed on the inner side of each spring. An adhesive layer is provided on the outer wall of the rotating drum and the right roller at the laterally aligned position.

[0006] Furthermore, each of the limiting expansion joints includes a set of round rods and cylinders that are slidably sleeved together, and the opposite ends of the round rods and cylinders are respectively fixedly connected to the end face of the moving ring and the inner wall of one side of the groove.

[0007] Furthermore, slide rails are fixedly connected to the outer walls of both sides of the two U-shaped frames, and slide grooves are slidably fitted onto the outer walls of the two slide rails on each side, with the two slide grooves respectively embedded in the inner walls of the two sides of the main frame.

[0008] Furthermore, rollers are fixedly connected to both sides of the bottom of the two U-shaped frames, and the wheel body of each roller makes rolling contact with the bottom inner wall of the main frame.

[0009] Furthermore, indicator strips are fixedly installed on the same side of the top of both U-shaped frames, and scale lines are distributed below both indicator strips, with the scale lines located on the top plane of one side of the main frame.

[0010] Furthermore, a mounting base is fixedly sleeved on the outer wall of the non-driving end in the middle of the bidirectional cylinder, and the bottom of the mounting base is fixedly connected to the inner wall of the bottom end of the main frame. Four mounting holes are rectangularly through-holes on both sides of the bottom end of the main frame.

[0011] In summary, this application includes the following beneficial technical effects: This application, through its main frame, U-shaped frame, left roller, right roller, and bidirectional cylinder, enables the groove, rotating drum, insertion hole, moving ring, insertion rod, spring, limit expansion joint, and lug on the left roller to achieve a winding and positioning function at both ends of the aluminum-plastic composite belt during tension testing. This overcomes the problem of easy loosening under force in traditional clamping methods and effectively improves the accuracy of tension testing of the aluminum-plastic composite belt.

[0017] Example: This application discloses an aluminum-plastic composite belt tension testing device. Please refer to [link / reference]. Figures 1 to 3The system includes a main frame 1, with U-shaped frames 2 distributed on both sides inside the main frame 1. A left roller 3 is fixedly installed on the inner wall of the upper end of the left U-shaped frame 2, and a right roller 4 is fixedly installed on the inner wall of the upper end of the right U-shaped frame 2. Extended protrusions are distributed in the middle of the inner wall of the bottom end of both U-shaped frames 2, and a bidirectional cylinder 5 is fixedly connected between the extended protrusions at the bottom end of the two U-shaped frames 2. A groove 6 is embedded in the outer wall of the middle part of the left roller 3. A rotating cylinder 7 is rotatably sleeved on one side of the groove 6. Multiple insertion holes 8 are evenly distributed around the circumference of one end face of the rotating cylinder 7. A moving ring 9 is slidably sleeved on the other side of the groove 6. Multiple insertion rods are evenly fixedly connected around the circumference of one end face of the moving ring 9. 10, and multiple insertion rods 10 are respectively connected to multiple insertion holes 8 in a one-to-one correspondence. Four springs 11 are uniformly fixedly installed at the connection between the other end face of the moving ring 9 and the inner wall of the groove 6. Multiple four ear blocks 13 are uniformly fixedly connected to the outer wall of the moving ring 9. Limiting expansion joints 12 are distributed on the inner side of each spring 11. Adhesive layers 14 are provided on the outer walls of the rotating drum 7 and the right roller 4 at the laterally aligned positions. The setting of adhesive layers 14 can improve the winding and fixing effect of the aluminum-plastic composite belt end on the outer surface of the rotating drum 7 and the right roller 4, while preventing the loosening problem of the end winding state during the stretching test.

[0018] Each limiting expansion joint 12 includes a set of round rods and cylinders that are slidably sleeved together. The opposite ends of the round rods and cylinders are fixedly connected to the end face of the moving ring 9 and the inner wall of one side of the groove 6, respectively. The setting of the limiting expansion joint 12 inside each spring 11 can effectively prevent the spring 11 from being passively twisted laterally. The outer wall of the non-driving end of the bidirectional cylinder 5 is fixedly sleeved with a mounting seat, and the bottom of the mounting seat is fixedly connected to the inner wall of the bottom end of the main frame 1. The mounting seat realizes the assembly and fixing function of the bidirectional cylinder 5. Four mounting holes 19 are rectangularly through-holes on both sides of the bottom end of the main frame 1. The four mounting holes 19 with a "T" shaped structure can cooperate with the assembly work of external bolt parts to realize the assembly and fixing function of the main frame 1 on the bearing plane.

[0019] Both sides of the outer walls of the two U-shaped frames 2 are fixedly connected with slide rails 15. The outer walls of the two slide rails 15 on each side are slidably fitted with slide grooves 16. The two slide grooves 16 are respectively embedded in the inner walls of the two sides of the main frame 1. Rollers 17 are fixedly connected to the bottom sides of the two U-shaped frames 2. The wheel body of each roller 17 is in rolling contact with the bottom inner wall of the main frame 1. Indicator strips 18 are fixedly installed on the same side of the top of the two U-shaped frames 2. Scale lines are distributed below the two indicator strips 18, and the scale lines are set on the top plane of one side of the main frame 1.

[0020] The implementation principle of this embodiment is as follows: During use, after cutting a length of the aluminum-plastic composite strip to be tested, one end is pasted onto the adhesive layer 14 on the outer wall of the right roller 4, while simultaneously wrapping that end partially around the outer wall of the right roller 4 several times (the specific number of wraps can be determined according to the length of the cut aluminum-plastic composite strip; the goal is simply to ensure that one end can be wrapped around and tightened on the outer wall of the right roller 4). Then, the other end of the aluminum-plastic composite strip is wrapped around and pasted onto the adhesive layer 14 on the outer wall of the rotating drum 7. Simultaneously, the ear block 13 pulls the moving ring 9 laterally, causing the moving ring 9 to move laterally on the groove 6, indirectly separating each insertion rod 10 from the insertion hole 8. At this time, each spring 11 is compressed and deformed, and the round rod in each limiting expansion joint 12 and the cylinder perform a limiting expansion and contraction movement. At this time, the rotating drum 7 can be manually operated to rotate on the groove 6, so that the other end of the aluminum-plastic composite strip continues to be wound around the outer wall of the rotating drum 7 several times until the middle of the aluminum-plastic composite strip is in a laterally taut state. After that, by finely adjusting the rotation angle of the rotating drum 7, the reset action of each spring 11 indirectly makes each insert rod 10 re-insert and position with each insert hole 8, and completes the winding positioning function before the tension detection of the aluminum-plastic composite strip to be tested. Then, under the synchronous drive of the two-way cylinder 5 to the two U-shaped frames 2 on both sides, the tensioning of the aluminum-plastic composite belt is indirectly achieved. In conjunction with the reading of the displacement values ​​of the indicator bars 18 and scale lines on both sides, the tension detection data of the aluminum-plastic composite belt is judged and calculated. During this process, each slide rail 15 is limited to sliding and cooperating with the inner wall of the slide groove 16, while each roller 17 performs rolling auxiliary support work.

[0021] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
