[0035] Reference Figure 1-5 An adjustable gauze trimming device is used in the trimming process of gauze processing. It allows for flexible adjustment of the blades according to processing needs, thereby improving processing efficiency.

[0036] The adjustable gauze trimming device includes a bracket 1, two rotating shafts 3, a slide bar 6, two blades 8, two threaded rods 7, and a drive mechanism.

[0037] The support 1 includes a base plate and two side plates set on the base plate, two rotating shafts 3 respectively set on the two side plates of the support 1, and the two rotating shafts 3 are coaxial. Two sliding rods 6 are provided and fixedly connected between the two rotating shafts 3. The axis of the two sliding rods 6 is parallel to the axis of the rotating shafts 3, thereby connecting the two rotating shafts 3. The two rotating shafts 3 can drive the sliding rods 6 to rotate. Two blades 8 are slidably connected to the sliding rods 6. By moving the blades 8, the distance between the two blades 8 can be changed, thereby flexibly adjusting the position of the blades 8 according to the trimming requirements of different fabrics.

[0038] Two threaded rods 7 are arranged between two rotating shafts 3 and are coaxial. One end of each threaded rod 7 is rotatably connected to a rotating shaft 3, and the other end of each threaded rod 7 is connected to a drive mechanism. A moving block 9 is fixedly connected to the middle of the two blades 8. The moving block 9 has a sliding hole and a threaded hole. The sliding rod 6 passes through the sliding hole, and the threaded rod 7 passes through the threaded hole, so that when the threaded rod 7 rotates, it can drive the blades 8 to move on the sliding rod 6. The sliding rod 6 has a scale for easy observation of the distance between the two blades 8.

[0039] The drive mechanism includes a fixed box 10, two first bevel gears 11 and a second bevel gear 12. One end of each of the two threaded rods 7 extends into the interior of the fixed box 10 and is fixedly connected to the two first bevel gears 11 respectively. The second bevel gear 12 is rotatably connected to the interior of the fixed box 10 and meshes with the two first bevel gears 11. The fixed box 10 has a through hole, and a knob 13 is rotatably connected to the through hole. The inner side of the knob 13 is fixedly connected to the second bevel gear 12, and the outer side has a hexagonal groove. The knob 13 can be rotated with a hexagonal screwdriver, thereby driving the second bevel gear 12 to rotate. The second bevel gear 12 drives the two first bevel gears 11 to rotate in opposite directions, thereby causing the two threaded rods 7 to rotate in opposite directions, driving the two blades 8 to move closer or further apart on the slide rod 6, thereby changing the distance between the two blades 8.

[0040] The bracket 1 is equipped with a drive motor, the output shaft of which is connected to the rotating shaft 3 to drive the rotating shaft 3 to rotate, thereby driving the blade 8 to rotate. The bracket 1 is equipped with a support roller 14, the axis of which is parallel to the axis of the blade 8, and the blade 8 is in contact with the outer wall of the support roller 14. The fabric passes between the blade 8 and the support roller 14, and is thus cut and trimmed by the blade 8.

[0041] The bracket 1 is equipped with a dust collection box 4 and a dust pump. The top of the dust collection box 4 is equipped with a dust collection pipe 5. When the fabric is trimmed, the dust pump can suck the cut fabric scraps into the dust collection box 4, which makes it easy to collect the fabric scraps. The dust collection pipe 5 is made of plastic corrugated pipe. Since the plastic corrugated pipe can be bent, it is easy to keep the opening of the dust collection pipe 5 always below the blade 8.

[0042] The support 1 is equipped with multiple rotating roller groups. Each rotating roller group includes two rotating rollers 2, and the outer walls of the two rotating rollers 2 are in contact. The fabric passes between the two rotating rollers 2, which facilitates the conveying of the fabric and makes it easier for the device to trim the fabric.

[0043] The working principle of the adjustable gauze trimming device is as follows: the fabric is conveyed by the rotating roller group, so that the fabric passes between the two rotating rollers 2, which facilitates the conveying of the fabric. When the fabric passes between the blade 8 and the support roller 14, the blade 8 cuts and trims the fabric.

[0044] When different trimming requirements of fabric need to be trimmed, the knob 13 is turned by the hex screwdriver. The knob 13 drives the second bevel gear 12 to rotate. The second bevel gear 12 drives the two first bevel gears 11 to rotate in opposite directions, thereby causing the two threaded rods 7 to rotate in opposite directions. The two threaded rods 7 respectively drive the two blades 8 to move closer or further apart on the slide rod 6, thereby changing the distance between the two blades 8 to adapt to different trimming requirements of fabric.

[0045] When trimming the fabric, the nozzle of the suction pipe 5 is positioned below the blade 8, and the fabric scraps cut during trimming are sucked into the dust collection box 4 by the suction pump, making it easy to collect the fabric scraps.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
