Description

Technical Field

[0002] High corrosion resistant foam tape is a type of tape that combines the elasticity and corrosion resistance of foam substrate. It uses chemically resistant foam as the core layer and is coated with acid and alkali resistant and solvent resistant adhesives on both sides. It can be used in harsh environments such as humidity, acid and alkali and salt spray for sealing, cushioning and fixing. It is used in chemical, marine and outdoor equipment scenarios. It can resist corrosion and maintain adhesion and elasticity.

Specifically, the bottom of the fixed base 41 is fixedly connected to the top of the base 1, providing an installation base for the slitting mechanism 4. The telescopic rod 42 is fixedly connected to the front and rear sides of the top of the fixed base 41, and can extend and retract to drive the slide rod 43 to move up and down. The slide rod 43 is rotatably connected between the adjacent telescopic rods 42, providing an installation and sliding carrier for the knife holder 44. The knife holder 44 is slidably connected to the outer wall of the slide rod 43, and can slide left and right to adjust the slitting width of the tape. The circular knife 45 is rotatably connected to the inner side of the knife holder 44, and contacts the tape to achieve slitting when the telescopic rod 42 extends. The locking screw 471 is threadedly connected to the top of the knife holder 44, and screws into the threaded hole 472 to lock the knife holder 44 and the slide rod 43.

[0021] Working principle: Place the tape roll on the unwinding shaft 371, thread the limiting cover 373 to the front side of the unwinding shaft 371, fix the tape roll after it is in place to prevent it from falling off, pull out one end of the tape and let it pass through the guide roller 372. The guide roller 372 guides the tape to go through, and then the tape passes under the circular knife 45 of the slitting mechanism 4 and continues to be pulled between the blade 35 and the bottom knife 33 of the cutting mechanism 3. Finally, fix the end of the tape on the take-up shaft 381. Adjust the slitting mechanism 4. According to the required slitting width, slide the knife holder 44 on the outer wall of the slide rod 43. The knife holder 44 can slide left and right on the outer wall of the slide rod 43 to adjust its position. After adjustment, screw the locking screw 471 into the threaded hole 472 at the top of the knife holder 44 to lock the knife holder 44 and the slide rod 43. Control the extension rod 42 at the top of the fixed base 41 to extend. The extension rod 42 drives the slide rod 43 to move up and down, so that the round knife 45 contacts the tape. Start the drive motor 46. The drive motor 46 drives the slide rod 43 to rotate. The slide rod 43 drives the round knife 45 on the inner side of the knife holder 44 to rotate, ready for slitting. The take-up motor 382 is started, which drives the take-up shaft 381 to rotate. The take-up shaft 381 pulls the tape to move. During the movement of the tape, the rotating circular blade 45 contacts the tape, realizing the slitting of the tape. The slitting tape continues to move to the cutting mechanism 3. The pressure strip 362 on the inner side of the lifting seat 361 on the left and right sides of the lifting guide rail 31 moves downward first, pressing down the tape on the left and right sides of the blade 35 before the blade 35 falls, preventing the tape from shifting during cutting. Then the hydraulic rod 32 on the inner side of the lifting guide rail 31 extends... The length of the hydraulic rod 32 causes the pressure sensor 34 and the blade 35 to move downwards. The blade 35 slides up and down along the inner side of the lifting guide rail 31. When the blade 35 touches the tape, the pressure sensor 34 detects the pressure on the blade 35. The blade 35 cuts the tape between the bottom blades 33 and the bottom blades 33. The bottom blades 33 provide support for the cutting of the blade 35. After the cutting is completed, the hydraulic rod 32 shortens, causing the blade 35 to move upwards and reset. The pressure bar 362 also slides upwards and resets. The winding shaft 381 continues to rotate, winding the cut tape around itself.
