Description

Technical Field

[0001] This utility model relates to the field of tarpaulin processing technology, specifically to a multi-segment cutting mechanism for tarpaulin cutting equipment. Background Technology

[0002] Tarpaulin (or waterproof fabric) is a high-strength, flexible, and waterproof material, commonly used as canvas, polyurethane-coated polyester, or made from polyethylene plastics. Tarpaulins usually have sturdy grommets at the corners or edges for easy threading of ropes for binding, hanging, or covering.

[0003] When cutting tarpaulins, the tarpaulin is usually fixed vertically, and then a linear module drives the cutter to cut the tarpaulin. This is convenient and fast. However, the linear module can only move the cutter horizontally and can only make horizontal cuts. The tarpaulin cutting style is relatively simple. Complex shapes can only be cut by other equipment, which has low applicability. Therefore, we propose a multi-segment cutting mechanism for tarpaulin cutting equipment. Utility Model Content

The upper end of the slide of each horizontal linear guide rail 33 is fixedly connected to a vertical linear guide rail 31. The inner sides of the slides of the two vertical linear guide rails 31 are provided with cutting components 32. The cutting component 32 includes a servo motor 321, a distance sensor 322, a blade 323, and a knife. The bracket 2 consists of a base 324 and a mounting base 325.

Through the detection of distance sensors 2 17 and 1 322, the front and rear horizontal linear guide rails 33 and the front and rear vertical linear guide rails 31 move synchronously. The output shafts of the front and rear servo motors 321 rotate synchronously, enabling the synchronous rotation of the two blade holders 324, facilitating cutting.

The input end of the controller 9 is electrically connected to an external power source, and the input ends of the vertical linear guide rail 31 and the horizontal linear guide rail 33 are both electrically connected to the output end of the controller 9.

[0026] The working principle of the multi-segment cutting mechanism for tarpaulin cutting equipment provided by this utility model is as follows: The tarpaulin roll is placed outside the feeding shaft 8, guiding the tarpaulin between the two conveying shafts 11. The motor 15 rotates, driving the rear conveying shaft 11. Through the meshing of two gears 10, the front conveying shaft 11 rotates in the opposite direction, realizing the conveying of the tarpaulin. The tarpaulin falls into the interior of the support 2. The telescopic end of the cylinder 5 extends, pushing the lower clamping plate 4 to move backward. The transverse linear guide rail 33 slides backward between the two slide rails 35, and the slide bar 13 slides backward between the slide column 12. The two lower clamping plates 4 clamp the lower end of the tarpaulin, the two upper clamping plates 14 clamp the upper end of the tarpaulin, and the two knife holders 324 also clamp the tarpaulin, reducing the vibration of the tarpaulin during cutting and making the cut smoother. The front transverse linear guide rail 33 drives the vertically adjacent vertical linear guide rails 11 to move backward. The guide rail 31 moves, enabling the blade 323 to move laterally. The second distance sensor 17 detects the distance between itself and the distance measuring plate 7 in real time, enabling the detection of the lateral position of the blade 323. The front vertical linear guide rail 31 drives the blade holder 324 to move vertically. The first distance sensor 322 detects the distance between the mounting base 325 and the slide of the front horizontal linear guide rail 33 in real time, enabling the detection of the vertical position of the blade 323. The servo motor 321 drives the front blade holder 324 and the blade 323 to rotate, enabling the adjustment of the blade 323's angle. Through the detection of the second distance sensor 17 and the first distance sensor 322, the lateral linear guide rails 33 on both the front and rear sides and the vertical linear guide rails 31 on both the front and rear sides move synchronously. The output shafts of the servo motors 321 on both the front and rear sides rotate synchronously, enabling the synchronous rotation of the two blade holders 324, which facilitates cutting.
