Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape processing, in particular to a strength detection device for adhesive tape processing. Background Art

[0002] Adhesive tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. A layer of adhesive is coated on its surface. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives, while various polymers are widely used in modern times. Adhesives can stick to things because bonds are formed between their own molecules and the molecules of the objects to be connected. This bond can firmly bond the molecules together.

[0003] At present, some existing strength detection devices use a method of direct stretching after clamping to detect the strength of the tape, but this method will cause the tape to deform at the clamping position, resulting in the tape being easily broken from the deformed clamping position during the test, resulting in inaccurate test results and relatively inconvenient use. For this reason, we propose a strength detection device for tape processing to solve or improve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a strength detection device for tape processing, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: it includes a test bench, support feet fixed to the bottom of the test bench, a slide groove opened on the top of the test bench, a support column slidably installed inside the slide groove, a winding roller rotatably installed on the top of the support column through a rotating shaft, a first limiting rod inserted into the inside of the support column, a first spring sleeved on the surface of the first limiting rod, and a fixing component A is arranged on one side of the top of the winding roller.

[0006] Furthermore, the fixing component A includes a fixing frame arranged on one side of the top of the winding roller, an adjusting screw inserted at the top of the fixing frame and threadedly connected to the fixing frame, a clamp fixed to the bottom of the adjusting screw, a second limiting rod inserted on the surface of the fixing frame, and a second spring fixed to the bottom of the second limiting rod.

[0007] Furthermore, a surface of the fixing frame on one side of the second limiting plug rod is provided with a groove, a push rod is fixed to the surface of the second limiting plug rod and the push rod passes through the inside of the groove provided on the surface of the fixing frame.

[0008] Furthermore, a driving motor is arranged on the surface of the test bench, and a driving screw is fixed to the top end of the output shaft of the driving motor. The driving screw passes through the interior of the supporting column and is threadedly connected to the supporting column.

[0009] Furthermore, a rotating hand wheel is fixed to one end of the rotating shaft of the winding roller, and one end of the rotating hand wheel passes through the interior of the supporting column and is rotatably connected to the supporting column.

[0010] Furthermore, two groups of slide grooves are symmetrically opened on the top of the test bench, and two groups of support columns are symmetrically slidably installed inside the two groups of slide grooves. Two groups of threads are set on the surface of the driving screw and the two groups of threads are in opposite directions. The driving screw passes through the interior of the two groups of support columns and is threadedly connected to the two groups of support columns at the same time through the two groups of threads.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by arranging a fixing component and a winding roller, the tape can be fixed to the top side of the winding roller through the fixing component when the strength of the tape needs to be tested. At this time, the tape can be wound on the surface of the winding roller by installing the fixing device on the top of the winding roller and rotating the winding roller. At this time, the driving motor drives the driving screw to rotate and drives the two groups of support columns to move, so that the two groups of support columns can drive the two groups of winding rollers to move in opposite directions to test the strength of the tape. At this time, most of the pulling force will act on the surface of the winding roller, thereby avoiding the deformation of the clamping part of the tape, which makes it very easy for the tape to break from the deformed clamping part during the test, resulting in inaccurate test results. It is relatively convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

A drive motor 3 is arranged on the surface of the test bench 1, a drive screw 15 is fixed to the top of the output shaft of the drive motor 3, and the drive motor 3 can carry The driving screw 15 fixed at the top of the dynamic output shaft rotates, and the driving screw 15 passes through the interior of the support column 4 and is threadedly connected with the support column 4. The surface of the driving screw 15 is provided with two sets of threads and the two sets of threads are in opposite directions. The driving screw 15 passes through the interior of the two sets of support columns 4 and is threadedly connected with the two sets of support columns 4 at the same time through the two sets of threads. When the driving screw 15 rotates, it will drive the two sets of threaded support columns 4 to move in opposite directions. The winding roller 5 is rotatably installed on the top of the support column 4 through the rotating shaft. The surface of the winding roller 5 is provided with a limiting hole, and the inner surface of the winding roller 5 is provided with a groove. A rotating hand wheel 7 is fixed at one end of the rotating shaft of the winding roller 5, and one end of the rotating hand wheel 7 passes through the interior of the supporting column 4 and is rotatably connected to the supporting column 4. When the rotating hand wheel 7 is rotated, the fixed winding roller 5 can be driven to rotate. The first limiting rod 6 is inserted into the interior of the supporting column 4, and a limiting plate is fixed to the surface of the first limiting rod 6. An auxiliary supporting plate is arranged on one side of the first limiting rod 6, and the limiting plate is located on the inner side of the auxiliary supporting plate. The auxiliary supporting plate cooperates with the limiting plate to limit the position of the first limiting rod 6 to prevent the first limiting rod 6 from detaching from the interior of the supporting column 4. The first spring 8 is sleeved The first spring 8 is arranged on the surface of the first limiting rod 6, one end of the first spring 8 contacts the limiting plate on the surface of the first limiting rod 6, and the other end contacts the auxiliary support plate. When the first limiting rod 6 moves, it will squeeze the first spring 8 to deform the first spring 8. When there is no external interference, the first spring 8 will push the first limiting rod 6 to move and return it to its initial position. The first limiting rod 6 can be inserted into the limiting hole opened on the surface of the winding roller 5. At this time, the position of the winding roller 5 can be limited by the first limiting rod 6, so that the winding roller 5 cannot rotate. The fixing component A is arranged on the top side of the winding roller 5.

[0021] The fixing component A includes a fixing frame 11 arranged on one side of the top of the winding roller 5. The fixing frame 11 can be inserted into the winding roller 5 through a groove set on the inner surface of the winding roller 5. The adjusting screw 10 is inserted at the top of the fixing frame 11 and is threadedly connected to the fixing frame 11, and is fixed to the clamping plate 12 at the bottom of the adjusting screw 10. When the adjusting screw 10 is rotated, it will move inside the fixed frame 11. When the adjusting screw 10 moves, it will drive the fixed clamping plate 12 to move. A limit rod is set on the top of the clamping plate 12. The limit rod passes through the inside of the fixed frame 11 and is slidably connected with the fixed frame 11. The limit rod can limit the position of the clamping plate 12 to prevent the clamping plate 12 from rotating itself. A second limit rod 13 is inserted on the surface of the fixed frame 11. A groove is set on the surface of the fixed frame 11 on one side of the second limit rod 13. A push rod is fixed on the surface of the second limit rod 13 and the push rod passes through the inside of the groove set on the surface of the fixed frame 11. When the push rod is pushed, the fixed second limit rod 13 can be driven to move. A limit rod is fixed on one side of the bottom of the second limit rod 13. The limit rod can be inserted into the second limit rod 13. The second limiting rod 13 is fixed to the bottom of the second limiting rod 13, and one end of the second spring 14 is fixed to the bottom of the second limiting rod 13, and the other end is fixed to the inner surface of the fixed frame 11. When the second limiting rod 13 moves, it will squeeze the second spring 14 to cause the second spring 14 to deform. When there is no external interference, the second spring 14 will push the second limiting rod 13 to move and return the second limiting rod 13 to its initial position. When the fixed frame 11 is inserted into the interior of the winding roller 5, the second limiting rod 13 can be inserted into the slot set on the inner surface of the winding roller 5, so that the fixing component A is relatively fixed to the interior of the winding roller 5 through the second limiting rod 13.

[0022] Working principle: when it is necessary to test the strength of the tape, one end of the tape is placed in the position inside the fixing frame 11 located on one side of the bottom of the clamping plate 12. At this time, the clamping plate 12 can be driven to move by rotating the adjusting screw 10, so that the clamping plate 12 clamps the tape between the surface of the clamping plate 12 and the fixing frame 11 to complete the fixation of the tape. The same is true for the other end. The fixing frame 11 with the tape fixed is then inserted into the inside of the winding roller 5 through the slot provided on the inner surface of the winding roller 5. The second spring 14 will push the second limiting rod 13 to move so that the second limiting rod 13 is inserted into the slot of the winding roller 5, thereby fixing the fixing frame 11 relatively to the inside of the winding roller 5. At this time, rotating the winding roller 5 can make the tape wind around the surface of the winding roller 5. When the winding When the winding roller 5 rotates to a certain angle, the first limit plug rod 6 will be inserted into the limit hole opened on the surface of the winding roller 5 to limit the position of the winding roller 5. At this time, the driving motor 3 drives the driving screw 15 to rotate and drives the two groups of support columns 4 to move in opposite directions, so that the two groups of support columns 4 can drive the two groups of winding rollers 5 to move in opposite directions, thereby stretching the tape to test its strength. At this time, most of the tension will act on the surface of the winding roller 5 and the tape wound on the surface of the winding roller 5, which greatly reduces the force on the tape at the clamping position of the splint 12 and the fixed frame 11, thereby avoiding the deformation of the clamping position of the tape, resulting in the tape easily breaking from the deformed clamping position during the test, resulting in inaccurate test results. It is relatively convenient to use.
