Technical Field

[0001] This utility model relates to the field of tarpaulin cutting technology, and more specifically to a tarpaulin cutting device for a board tennis tent. Background Technology

[0002] As a rapidly developing emerging sport in recent years, paddle tennis has seen a significant increase in demand for its supporting venue facilities. Portable tents, with their advantages of rapid setup, flexible layout, and all-weather protection, have become the mainstream covering solution for paddle tennis courts. These tents typically use high-strength flexible composite materials as the main fabric, which need to be cut according to the tent structure to ensure airtightness, wind load resistance, and visual flatness.

[0003] A search revealed a Chinese patent with publication number CN222100480U, which discloses a cutting machine for producing and processing high-strength tarpaulins. If the tarpaulin is in a loose state during the cutting process, the cutting will be biased, resulting in uneven edges on the cut tarpaulin and affecting its appearance. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1-4This utility model provides a fabric cutting device for a panel tennis tent, including a workbench 1. Two sets of symmetrical vertical plates 3 are bolted to the upper surface of the workbench 1, each set consisting of two symmetrical plates. Two pressure rollers 4 are rotatably connected between opposite sides of the two vertical plates 3 in the same set. Highly elastic rubber rings 5 ​​are adhered to the outer circumference of each pressure roller 4. Two symmetrical fixing frames 13 are bolted to the upper surface of the workbench 1 between the two sets of vertical plates 3. Two sliding rods 14 are bolted between the two fixing frames 13. Two symmetrical sliding frames 15 are slidably connected to the two sliding rods 14. An inclined cutting blade 16 is bolted to the upper surface of each of the two sliding frames 15. A tensioning component 9 for pressing the fabric is located on the upper surface of the workbench 1 between the two sets of vertical plates 3. A flattening component 2 for flattening the fabric is located at one end of the upper surface of the workbench 1. Two extrusion rollers 4 are connected to gears 10 by bolts through one side of vertical plate 3 at the same end, and the two gears 10 mesh with each other. Two fixed frames 13 are rotatably connected to opposite sides by bearings via a double-acting screw 17. The double-acting screw 17 passes through two slides 15 and is threaded to them. Both ends of the double-acting screw 17 pass through one side of fixed frame 13 and are bolted to a rotating disk. When the tarpaulin needs to be cut, the double-acting screw 17 is rotated first, which drives the two slides 15 threaded to it to move along slide bar 14 in a direction that is closer to or further away from each other, and then the width to be cut is adjusted as needed. After adjustment, the tarpaulin is passed through flattening assembly 2, then through two sets of extrusion rollers 4 and then wound onto the winding assembly. The two sets of extrusion rollers 4 can keep the tarpaulin taut when cutting both sides of the tarpaulin, preventing the tarpaulin from loosening during the cutting process and causing cutting deviation.

[0022] In this invention, the flattening assembly 2 includes two fixed plates 201 symmetrically positioned on the left side of the upper surface of the workbench 1, fixed by bolts. A flattening roller 202 is rotatably connected between the opposite sides of the two fixed plates 201 via bearings. One end of the flattening roller 202 shaft passes through one side of the fixed plate 201 and is fixedly connected to a driven pulley 12 by bolts. One end of the extrusion roller 4, located near and below the flattening roller 202, passes through one side of the vertical plate 3 and is fixedly connected to a driving pulley 11 by bolts. The driving pulley 11 and the driven pulley 12 are connected by a belt. The belt drive connection allows the tarpaulin to rotate in opposite directions as it passes between the two compression rollers 4. This rotation, caused by the elastic rubber ring 5, causes the drive pulley 11 to rotate and the driven pulley 12 to rotate synchronously via the belt. This, in turn, causes the flattening roller 202 to rotate and flatten the tarpaulin. The flattening assembly 2 provides an outward expanding force to the tarpaulin as it passes the flattening roller 202, thus flattening the wrinkled areas and preventing deviations during cutting.

[0023] In this invention, the tensioning assembly 9 includes two sets of round rods 18 fixedly connected to the upper surface of the workbench 1 by bolts, with two rods in each set. Each set of two round rods 18 is slidably connected to a slide frame 19. The lower surface of the slide frame 19 has two symmetrical connecting plates 20 connected by bolts. A rotating roller 21 is rotatably connected between the opposite sides of the two corresponding connecting plates 20 by bearings. A threaded rod 22 is threaded through the middle part of the slide frame 19, and the bottom end of the threaded rod 22 is rotatably connected to the upper surface of the workbench 1 by bearings. If the tarpaulin becomes loose, rotating the threaded rod 22 will drive the slide frame 19 connected to it to move downward along the round rods 18, thereby driving the rotating roller 21 to move downward. During the downward movement of the rotating roller 21, the tarpaulin is squeezed. By means of the tensioning assembly 9, if the tarpaulin becomes loose during the processing, the rotating roller 21 can be squeezed by rotating the threaded rod 22, thereby keeping the tarpaulin in a taut state.

[0024] In this utility model, two symmetrical vertical plates 6 are fixedly connected to one end of the upper surface of the workbench 1 by bolts. A winding roller 7 is rotatably connected between the opposite sides of the two vertical plates 6. A drive motor 8 that can rotate the vertical plate 6 along the axial direction is fixedly connected to one side of one of the vertical plates 6 by bolts. When the tarpaulin is cut, the tarpaulin is wound onto the winding roller 7, and the cut tarpaulin is wound up by starting the drive motor 8.

[0025] The use of this utility model involves the following steps:

[0026] S1: When the tarpaulin needs to be cut, first rotate the bidirectional screw 17 to drive the two slides 15 connected to it to move along the slide 14 in a direction that is closer to or further away from each other, and then adjust the width according to the required cutting width. After the adjustment is completed, the tarpaulin passes through the flattening component 2, then through the two sets of extrusion rollers 4, and then is wound onto the winding component.

[0027] S2: When the tarpaulin passes between the two squeezing rollers 4, the elastic rubber ring 5 will cause the two squeezing rollers 4 to rotate in opposite directions, thereby causing the drive pulley 11 to rotate and drive the driven pulley 12 to rotate synchronously through the belt, so that the flattening roller 202 rotates to flatten the tarpaulin.

[0028] S3: If the tarpaulin becomes loose, rotate the threaded rod 22 to drive the slide 19 connected to it to move downward along the round rod 18, which in turn drives the rotating roller 21 to move downward. During the downward movement of the rotating roller 21, the tarpaulin is squeezed.

[0029] S4: When the tarpaulin is cut, the tarpaulin is wound onto the take-up roller 7, and the cut tarpaulin is taken up by starting the drive motor 8.

[0030] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
