A method and device for detecting adhesive tape tension

Abstract

The present invention belongs to the field of adhesive tape tension detection, and specifically, is a method and device for detecting adhesive tape tension. The adhesive tape tension detection device comprises: a frame, support blocks are arranged at the top and bottom of the frame, a movable block is arranged at the front end of the support block, and a connecting block is fixed at the front end of the movable block. In the present invention, the adhesive tape is wound on a fork frame, and more of the adhesive tape surface contacts with the fork rod of the fork frame, thereby increasing the friction force. When the tension acts on the adhesive tape, the friction force will prevent the adhesive tape from sliding, so that the position of the adhesive tape on the fork frame is more stable, which is manifested as being more tightly wound on the fork frame. Secondly, the multi-layer structure formed by winding will also increase the friction force between layers. When each layer of adhesive tape is subjected to tension, it will generate pressure on the adjacent adhesive tape layer, thereby increasing the friction force between layers. The friction force will make the entire adhesive tape roll more tightly combined together, further enhancing the stability of the adhesive tape on the fork frame.

Description

Technical Field

[0001] The invention belongs to the field of adhesive tape tension detection, in particular to an adhesive tape tension detection method and device. Background Art

[0002] Adhesive tape is a kind of sticky strip material that plays an important role in daily life and many industries. During the production process of adhesive tape, it needs to pass strict tensile testing to ensure that the produced tape can withstand the specified tensile force without breaking or being damaged in actual use.

[0003] The prior art also proposes some solutions for tape tension detection. For example, a patent with announcement number CN220772783U discloses a PVC tape tension testing device, including a shell, and two sets of fixed blocks are fixedly connected to the top outer wall of the shell. The outer wall of the fixed block is provided with a slide groove. The patent places the top of the tape between the upper clamping block A and the upper clamping block B to prevent the tape from falling off during the test and affecting the test process. The fixing process is more convenient and the work efficiency is improved.

[0004] Although the above technical solution can clamp the ends of the tape by means of the clamping blocks, when the tension test of the tape is performed, the two ends of the tape are easily pulled out from between the clamping blocks by the tension, which affects the detection process. In addition, after the tape is broken, the clamping blocks need to be opened to take out the broken tape before the next tape can be clamped, which is inconvenient.

[0005] To this end, the present invention provides a method and device for detecting the tension of an adhesive tape. Summary of the invention

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] A method for detecting the tension of a tape according to an embodiment of the present invention comprises the following steps:

[0039] S1. Determine the testing standards. According to the purpose of the tape and relevant industry standards, determine the applicable tensile testing standards and clarify the test index requirements, such as the maximum tensile value;

[0040] S2. Prepare the testing device and select a tape tension testing device with appropriate range and accuracy to ensure that the tension of the tape can be accurately measured;

[0041] S3. Sample preparation: randomly select a certain number of samples from the same batch of tapes to ensure that the samples are representative, and cut the tapes into specified sizes and shapes according to standard requirements;

[0042] S4. Install the tape sample, fix one end of the tape on a clamp of the tape tension test device, ensure that the tape is clamped flat and without wrinkles, and then fix the other end of the tape on another clamp of the tape tension test device, also ensure that it is clamped firmly;

[0043] S5. Start the test. After confirming that the sample is installed correctly and the test parameters are set correctly, start the tape tension detection device and start the tension test. The tape tension detection device stretches the tape according to the set parameters and records the tension value and displacement data at the same time.

[0044] S6. Observe the key moments. As the tension increases, always pay attention to the changes in the tape. When the tape begins to deform slightly, crack, or make special sounds, observe more attentively and continue to stretch until the tape is broken. At this time, accurately record the instantaneous tension value, which is the maximum tension value of the tape sample. At the same time, observe the way the tape breaks, whether it breaks neatly or in an irregular tearing shape, to provide more information for analyzing the performance and quality of the tape.

[0045] S7. Data analysis: After the test is completed, the tape tension detection device generates a test data curve, including tension and displacement curves. By analyzing these curves, the maximum tension value and elongation at break performance indicators of the tape are obtained.

[0046] like Figures 1 to 8 As shown, a tape tension detection device comprises: a frame 1, support blocks 2 are arranged at the top and bottom of the frame 1, a movable block 3 is arranged at the front end of the support block 2, a connecting block 4 is fixed at the front end of the movable block 3, a fork frame 5 is arranged at the front end of the connecting block 4, a motor 3 7 is installed at the rear end of the support block 2, the rotating shaft of the motor 3 7 protrudes from the front part of the support block 2 and is fixedly connected to the back of the movable block 3, and a telescopic rod 6 is installed at the top and bottom ends of the frame 1, and the output ends of the telescopic rod 6 extend to the inside of the frame 1 and are respectively connected to the support block 2.

[0047] The fork frame 5 is divided into two upper and lower fork rods. One end of the tape is passed through the fork frame 5, so that the end of the tape is wound around the fork rod above the fork frame 5, and the adhesive surface of the tape is attached to the upper fork rod. The other end of the tape is fixed to the other fork frame 5 in the same way. The motor 3 7 is started to drive the movable block 3, the connecting block 4 and the fork frame 5 to rotate 360°. The tape is wound around the fork frame 5 to fix the two ends of the tape.

[0048] First, as the adhesive tape is wound on the fork frame 5, more of the adhesive tape surface contacts the fork rod of the fork frame 5, thereby increasing the friction. When tension acts on the adhesive tape, this friction will prevent the adhesive tape from sliding, making the position of the adhesive tape on the fork frame 5 more stable, which is manifested as being wound more tightly on the fork frame 5. Secondly, the multi-layer structure formed by winding will also increase the friction between the layers. When each layer of adhesive tape is subjected to tension, it will exert pressure on the adjacent layers of adhesive tape, thereby increasing the friction between the layers. This friction will make the entire adhesive tape roll more tightly combined together, further enhancing the stability of the adhesive tape on the fork frame 5. In addition, the front end of the fork frame 5 is an open design. After the adhesive tape is broken, the wound adhesive tape can be pulled along the direction of the fork rod on the fork frame 5 to remove the adhesive tape.

[0049] The telescopic rod 6 is started to drive the support block 2 to move, and the support block 2 drives the fork frame 5 to follow the movement to stretch the two ends of the tape. The tape tension detection device stretches the tape according to the set parameters and records the tension value and displacement data at the same time.

[0050] like Figures 1 to 8 As shown, the connecting block 4 is rotatably provided with a built-in block 36, the front end of the built-in block 36 is fixedly connected to the fork frame 5, slots 2 32 are provided on both sides of the connecting block 4, side grooves 362 are provided on both sides of the built-in block 36, a spring 1 363 is fixed inside the side groove 362, a positioning block 361 is fixed at the end of the spring 1 363, the positioning block 361 is snapped into the inside of slot 3 364, slot 3 364 is provided at the middle position of one side of slot 2 32, two slots 364 are located on both sides of the built-in block 36, and slot 3 364 is connected with slot 2 32, and rods 34 are provided on both sides of the upper and lower ends of the frame 1, the positions of the rods 34 and slot 2 32 are exactly corresponding, the rods 34 are fixed on the support plate 35, and the support plate 35 is fixed on the inner wall of the frame 1.

[0051] In the default state, the positioning block 361 is pushed into the slot 3 364 by the elastic force of the spring 1 363 and placed in the slot 2 32. The positioning block 361 is stuck in the slot 3 364 to fix the position of the built-in block 36, so that the built-in block 36 is fixed and the fork frame 5 fixedly connected to the built-in block 36 remains stationary.

[0052] After the tape is pulled off, the tape is divided into two and broken into two sections and placed outside the two fork frames 5 respectively. The telescopic rod 6 is started to continuously drive the two support blocks 2 to move toward the upper and lower ends inside the frame 1 respectively, and the connecting block 4 moves toward the position of the insertion rod 34. When the insertion rod 34 is inserted into the second slot 32, the inclined portion of the insertion rod 34 moves toward the inclined portion of the positioning block 361, and pushes the positioning block 361 to push it out of the third slot 364 and the second slot 32 and retract it into the connecting block 4. At this time, the built-in block 36 loses the fixation of the positioning block 361 and can rotate in the connecting block 4, and the fork frame 5 fixedly connected to the connecting block 4 can move with it.

[0053] like Figures 1 to 8As shown, a rotating column 37 is provided at the front end of the movable block 3, and the front end of the rotating column 37 extends to the inside of the connecting block 4 and is fixedly connected to the back of the built-in block 36. A gear ring 38 is fixed to the outside of the rotating column 37. A slot 31 is provided on the right side of the movable block 3. A rack 33 is provided on the right side of the upper and lower ends of the frame 1, and the positions of the rack 33 and the slot 31 correspond exactly. The rack 33 is fixed on the support plate 35 and is located behind the insertion rod 34. A support plate 39 is provided behind the rotating column 37, and the support plate 39 is fixed on the inner wall of the movable block 3. A rotating block 392 is rotatably provided inside the supporting plate 39, and the front end of the rotating block 392 protrudes from the front part of the supporting plate 39 and is fixedly connected to the rotating column 37.

[0054] After the tape is broken, the telescopic rod 6 is started to continuously drive the two support blocks 2 to move toward the upper and lower ends of the inside of the frame 1, and the movable block 3 moves toward the position of the rack 33. When the rack 33 is inserted into the slot 31, the rack 33 drives the meshing gear ring 38 to rotate, and the gear ring 38 drives the rotating column 37 to rotate accordingly. At the same time, the built-in block 36 and the fork frame 5 fixedly connected to the rotating column 37 rotate. At this time, the rotating fork frame 5 winds up the tape broken into two sections, so that the tape is rolled up to the outside of the fork frame 5.

[0055] It should be noted that the length of the insertion rod 34 is longer than that of the rack 1 33. The insertion rod 34 is first inserted into the slot 2 32 to push the positioning block 361 out of the slot 3 364. After the fixing of the built-in block 36 is released, the rack 1 33 is inserted into the slot 1 31 to drive the gear ring 1 38 to rotate. The purpose of this design is to prevent the insertion rod 34 and the rack 1 33 from acting at the same time to cause interference.

[0056] When the rotating column 37 rotates under the action of the gear ring 1 38, the rotating column 37 drives the rotating block 392 to rotate in the supporting plate 39. When the next tape detection is performed, the telescopic rod 6 pushes the two supporting blocks 2 to move towards each other. At this time, the rack 1 33 is moved out of the slot 1 31, and the plug 34 is moved out of the slot 2 32. The rack 1 33 drives the gear ring 1 38 to reverse and reset the rotating column 37. The built-in block 36 and the fork frame 5 rotate with the rotating column 37, and the built-in block 36 is reset to the position as shown in the figure. Figure 4 In the position shown, when the insertion rod 34 loses its pressure on the positioning block 361, the positioning block 361 is pushed into the slot three 364 by the elastic force of the spring one 363, thereby fixing the position of the built-in block 36.

[0057] like Figures 1 to 8As shown, a push plate 41 is provided at the front end of the connecting block 4, and the push plate 41 is sleeved on the outside of the fork frame 5. Side frames 49 are fixed on both sides of the push plate 41, and a connecting frame 410 is fixed on the outside of the side frame 49. A touch block 481 is fixed on the top of the side frame 49 on the right side of the push plate 41. Screws 42 are provided on both sides above and below the inside of the frame 1, and a motor 44 is provided at the rear end of the screw 42. A threaded block 43 is connected to the external thread of the screw 42, and a connecting plate 45 is fixed on one side of the threaded block 43. An insert block 46 is fixed on the connecting plate 45, and the position of the insert block 46 corresponds to that of the connecting frame 410. A switch 48 is provided on the connecting plate 45 on the upper and lower right sides of the inside of the frame 1, and the position of the switch 48 corresponds to that of the touch block 481. A knife groove 413 is opened inside the push plate 41, and a shift block 414 is provided in the knife groove 413. A knife body 415 is fixed to the front of the shift block 414, and the knife body 415 is located on the outer periphery of the fork frame 5.

[0058] The push plate 41 is fixed to the front end of the connecting block 4 through a clamping block and a clamping slot. The specific structure of the clamping block and the clamping slot is not shown in the figure. The clamping block can be provided at the back of the push plate 41, and the clamping slot can be provided at the front end of the connecting block 4. The push plate 41 fits the front end of the connecting block 4, and the clamping block is inserted into the clamping slot, so that the push plate 41 can be fixed to the front end of the connecting block 4.

[0059] After the tape is broken, the telescopic rod 6 is started to continuously drive the two support blocks 2 to move toward the upper and lower ends inside the frame 1, respectively, and the connecting frames 410 on both sides of the push plate 41 move toward the plug block 46, and the plug block 46 is inserted into the connecting frame 410, completing the connection between the threaded block 43 and the push plate 41. When the connecting plate 45 is in close contact with the end of the connecting frame 410, the touch block 481 at the end of the side frame 49 contacts the switch 48 on the connecting plate 45, and the switch 48 starts the control motor 2 44 to start;

[0060] Motor 2 44 drives screw 42 to rotate and pushes threaded block 43 to move. Under the action of threaded block 43, push plate 41 moves outside fork frame 5 and pushes the tape wound outside fork frame 5, pushing the tape out from outside fork frame 5, thus completing the tape unloading operation.

[0061] like Figures 1 to 8As shown, the push plate 41 is internally rotated with a gear ring 411, which is located at the rear end of the shift block 414, and a top block 412 is fixed to the front of the gear ring 411. A gear 418 is meshed on the right side of the gear ring 411, and the right side of the gear 418 is placed inside the side frame 49. A rack 47 is fixed on the connecting plate 45 on the upper and lower right sides of the frame 1, and the position of the rack 47 corresponds to that of the side frame 49, and the rack 47 is located behind the insertion block 46. Reset blocks 416 are fixed on both sides of the shift block 414, and a spring 417 is fixed to the front end of the reset block 416, and the front end of the spring 417 is fixed to the inner wall of the knife groove 413. The rack 47 can be vertically inserted into the side frame 49 and drive the meshing gear 418 to rotate.

[0062] After the adhesive tape is broken, the telescopic rod 6 is started to continuously drive the two support blocks 2 to move toward the upper and lower ends inside the frame 1 respectively, and the side frame 49 on the right side of the push plate 41 moves toward the second rack 47, and the second rack 47 is inserted into the side frame 49, and drives the meshing gear 418 to rotate, and the gear 418 drives the second gear ring 411 to rotate, and the second gear ring 411 drives the top block 412 to move toward the position of the shift block 414, and gradually pushes the shift block 414, and the knife body 415 fixedly connected to the shift block 414 extends from the knife groove 413. When the push plate 41 moves, the extended knife body 415 can cut the adhesive tape wound on the outside of the fork frame 5, so that the adhesive tape will not be too tightly wrapped around the outside of the fork frame 5, resulting in difficulty in being pushed by the push plate 41, which affects the problem of material unloading;

[0063] Among them, when the shifting block 414 retracts into the knife groove 413 due to the thrust of the top block 412, the shifting block 414 drives the reset block 416 to move, and the reset block 416 squeezes the spring 2 417 to contract. When the rack 2 47 moves out of the side frame 49, the rack 2 47 drives the gear 418 to reverse, and the gear 418 drives the gear ring 2 411 to reverse, and the gear ring 2 411 drives the top block 412 away from the shifting block 414. The shifting block 414 loses the pressure of the top block 412, and the elastic force of the spring 2 417 pushes the reset block 416 to reset the shifting block 414, and the reset shifting block 414 drives the knife body 415 to retract into the knife groove 413.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
