Description

A tape stretching detection device

Technical Field

The invention relates to the technical field of adhesive tape production detection, and in particular to an adhesive tape stretching detection device.

Background technique

After the tape is produced, it needs to be sampled and tested. Tensile testing is one of the testing items. Tensile testing is to slowly pull a material sample under the action of an axial force until it breaks. The tensile test is to determine the yield strength, tensile strength and elongation of the material. During the test, attention should be paid to observing the changes between tension and deformation.

When using an existing tape stretching detection device, the two ends of the tape are usually fixed and then stretched to test its strength. However, after the test, adhesive will adhere to its surface. If it is not cleaned, impurities and dust will easily adhere to its surface, reducing the effect of subsequent tests and hindering the rapid development of the device detection work.

Working principle: when in use, attach the two ends of the tape to be tested to the top wall of the L-shaped plate 76 respectively, then turn the knob to drive the screw 77 to rotate, and the rotation of the screw 77 will drive the clamping plate 78 to move downward, and the clamping plate 78 will clamp and fix the tape when it moves downward. After the clamping and fixing is completed, the movable gear 72 can be driven to rotate by the operation of the servo motor A71, and the movable gear 72 will drive the rack plate A73 and the rack plate B74 to move in the opposite direction when the rack plate A73 and the rack plate B74 move in the opposite direction, and the L-shaped moving rod 75 will drive the L-shaped plate 76 to move in the opposite direction when the L-shaped plate 76 moves in the opposite direction, and the tape will be stretched when the L-shaped plate 76 moves in the opposite direction, and the test data can be obtained through the scale, and the operation is convenient. After the test is completed, the L-shaped plate 76 can be restored to its original position, and then the staff can take out the test piece. The measured tape is then driven by the operation of the servo motor B84 to drive the threaded rod 81 on one side to rotate, and the transmission of the belt 83 will drive the threaded rods 81 on both sides to rotate. When the threaded rod 81 rotates, it will drive the threaded sleeve 82 to move forward. When the threaded sleeve 82 moves forward, it will drive the guide plate 85 to move forward under the action of the guide rod 851, and when the guide plate 85 moves forward, it will drive the ball 86 to move forward. When the threaded sleeve 82 moves forward, it will also drive the moving block 87 to move through the vertical rod. When the moving block 87 moves, it will drive the cleaning plate 88 and the spray pipe 89 to move through the straight plate. When the cleaning plate 88 moves, it will clean the adhesive on the top of the L-shaped plate 76. When the servo motor B84 is started, the cooling fan 894 and the electric heating net 893 can be operated. When the cooling fan 894 is running Wind force will be generated, and the wind will be heated by the operation of the electric heating net 893. Then, the spray pipe 89 will blow hot air to the surface of the L-shaped plate 76 through the second duct, the hose 891 and the first duct, so that the adhesive can be pushed off better. After the cleaning plate 88 cleans to a certain position on the L-shaped plate 76, the ball 86 will contact the positive trapezoidal block 51, thereby squeezing it to move downward. When the positive trapezoidal block 51 moves downward, it will squeeze the telescopic spring B511, and when the positive trapezoidal block 51 moves downward, it will drive the sliding plate 52 to move downward. When the sliding plate 52 moves downward, it will drive the L-shaped rod 53 to drive the movable plate 54 to move through the inclined groove. When the movable plate 54 moves, it will drive the push rod 56 to move through the push block 55. When the push rod 56 moves, it will push the trapezoidal block A43 to move. When the movable groove 42 moves, the telescopic spring A431 will drive the movable groove 42 to move. When the movable groove 42 moves, the scraper 45 will also be driven to move and squeeze the reset spring 423. When the trapezoidal block A43 moves to contact the trapezoidal block B44, the telescopic spring A431 will be squeezed to make it move backward, so that the trapezoidal block A43 is separated from the push rod 56. At this time, the movable groove 42 will drive the scraper 45 to recover under the action of the rebound force of the reset spring 423, and the push rod 56 will also stop moving. At the same time, the cleaning plate 88 will also move to the outside of the L-shaped plate 76, and then the recovered scraper 45 will scrape off the adhesive on the stopped cleaning plate 88. Because the scraper 45 is non-adhesive, the adhesive on the cleaning plate 88 can be pushed into the cleaning groove 46 for collection, which is convenient for the staff to handle later.
