Description

Technical Field

[0041] 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, which is convenient to operate. After the test is completed, the L-shaped plate 76 can be restored to its original position , and then the staff takes out the tested tape, and then drives the threaded rod 81 on one side to rotate through the operation of the servo motor B84, and the transmission of the belt 83 drives the threaded rods 81 on both sides to rotate, and the threaded rod 81 rotates, which drives the threaded sleeve 82 to move forward, and the threaded sleeve 82 moves forward, which drives the guide plate 85 to move forward under the action of the guide rod 851, and the guide plate 85 moves forward. The ball 86 moves forward, and the threaded sleeve 82 moves forward and drives the moving block 87 to move through the vertical rod. When the moving block 87 moves, it drives the cleaning plate 88 and the spray pipe 89 to move through the straight plate. When the cleaning plate 88 moves, the adhesive on the top of the L-shaped plate 76 is cleaned, and when the servo motor B84 is started, the cooling fan 894 and the electric When the heating net 893 is running and the heat dissipation fan 894 is running, wind will be generated. The operation of the electric heating net 893 will heat the wind, and 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 also 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 55 through the push block 55. 6 moves, and when the push rod 56 moves, it will push the trapezoidal block A43 to move. When the trapezoidal block A43 moves, it will drive the moving groove 42 to move through the telescopic spring A431. When the moving groove 42 moves, it will also drive the scraper 45 to move and squeeze the reset spring 423. When the trapezoidal block A43 moves to contact the trapezoidal block B44, it will squeeze the telescopic spring A431 to move it backward, so that the trapezoidal block A43 and the push rod 56 are separated. At this time, the moving 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 this time. 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 has a non-stick property.The adhesive on the cleaning plate 88 can be pushed into the cleaning tank 46 for collection, which is convenient for the staff to handle later.
