[0033] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] like Figures 1 to 7The feeding device of a gauze cutting machine shown includes: a worktable 100, a fixed plate 150 at the top of the worktable 100, a feeding component 200 slidably connected to one side of the fixed plate 150, and a positioning component 300 slidably connected to the fixed plate 150 on one side of the feeding component 200.

[0035] The feeding assembly 200 includes a first clamping plate 210 slidably connected to the top of the fixed plate 150. A vertical plate 220 is fixed to one side of the first clamping plate 210. A connecting plate 230 is fixed to the upper end of the side of the vertical plate 220 near the first clamping plate 210. A second clamping plate 240 is provided directly below the connecting plate 230 and slidably connected to one side of the vertical plate 220. Long plates 250 are fixed to both sides of the vertical plate 220. Guide plates 260 are fixed to the ends of the two sets of long plates 250 away from the vertical plate 220. A round shaft 270 is fixed to one side of one set of guide plates 260. The 0 has a connecting pipe 280 inside, which passes through the guide plate 260, the long plate 250 and the vertical plate 220. The end of the connecting pipe 280 away from the round shaft 270 is connected to a diversion pipe 281. The end of the diversion pipe 281 is slidably connected to a telescopic pipe 282. The bottom end of the telescopic pipe 282 is fixed to the second clamping plate 240. The round shaft 270 has an air storage groove 290 on the side near the connecting pipe 280. The air storage groove 290 is slidably connected to a piston rod 2910. A return spring 2920 is sleeved on the surface of the piston rod 2910.

[0036] The positioning assembly 300 includes movable grooves 311 formed on both sides of the top of the fixed plate 150. Movable blocks 310 are slidably connected inside each of the two sets of movable grooves 311. Positioning plates 320 are fixed to the top of each set of movable blocks 310, and each movable block 310 has a groove 330 inside. A sliding plate 340 is provided inside the groove 330. A retaining shaft 350 is fixed to one side of the sliding plate 340, and a rope 360 ​​is fixed to the other side of the sliding plate 340. A limiting spring 370 connected to one side of the groove 330 is sleeved on the surface of the rope 360. A number of slots 351 for matching the locking shaft 350 are opened on one side of the moving groove 311. A U-shaped frame 110 is installed at the middle of the top of the worktable 100. An electric push rod 120 is installed at the top of the U-shaped frame 110. A spring pressure plate 130 is fixed at the end of the movable rod of the electric push rod 120. A cutting blade 140 is provided on one side of the spring pressure plate 130. Two sets of support frames 160 are provided on the side of the fixed plate 150 away from the positioning plate 320. Feeding rollers 170 are snapped into the two sets of support frames 160. Gauze 180 is wrapped around the surface of the feeding rollers 170.

[0037] The operator places the feeding roller 170, wrapped with gauze 180, on the support frame 160 for locking. Then, the gauze 180 is pulled to the top of the fixing plate 150. Pulling the pull plate 380 moves the ropes 360 on both sides, causing the ropes 360 to pull the sliding plate 340, compressing the limiting spring 370 and simultaneously moving the locking shaft 350 towards the groove 330 until the locking shaft 350 disengages from the locking slot 351, releasing the fixation between the moving block 310 and the fixing plate 150. Then, by moving the positioning plate 320 to the desired position and releasing the pull plate 380, the locking shaft 350 is re-embedded in the locking mechanism under the action of the limiting spring 370. The groove 351 is fixed inside. By adjusting the positioning plate 320, the cutting size of the gauze 180 can be quickly adjusted according to actual needs, enhancing the versatility and adaptability of the equipment, while also avoiding waste and improving resource utilization. After adjustment, the round shaft 270 is pushed, causing it to move a set of guide plates 260 and a set of long plates 250 synchronously. The long plates 250 move the vertical plate 220, another set of long plates 250, and the guide plates 260, causing the vertical plate 220 to move the first clamping plate 210 towards the gauze 180. When the first clamping plate 210 moves to below one end of the gauze 180, it can be adjusted by pressing... Pressing the piston rod 2910 stretches the return spring 2920 and compresses the gas inside the gas storage tank 290. This gas then enters the diversion pipe 281 through the connecting pipe 280. Under the pressure of the gas, the telescopic pipe 282 extends out of the diversion pipe 281, causing the telescopic pipe 282 to move the second clamping plate 240 downwards until it contacts the top of the gauze 180. The first clamping plate 210 and the second clamping plate 240 effectively clamp and fix the gauze 180. Then, pulling the round shaft 270 causes the first clamping plate 210 and the second clamping plate 240 to move the gauze 180 synchronously until it is vertical. One side of plate 220 is attached to positioning plate 320. The first clamping plate 210 and the second clamping plate 240 feed the gauze 180 to ensure that the gauze 180 maintains a fixed position and a stable moving speed during the cutting process, thereby avoiding errors caused by the movement of the gauze 180 and improving the cutting accuracy. At the same time, it also effectively prevents the gauze 180 from shifting or twisting during the feeding process, ensuring the stability of the feeding. At this time, the electric push rod 120 is activated to move the spring pressure plate 130 and the cutting blade 140 downward. The spring pressure plate 130 presses one side of the gauze 180, and the cutting blade 140 completes the cutting of the gauze 180.

[0038] In this embodiment, two sets of sliders 241 are welded to one side of the second clamping plate 240, and a groove 242 matching the sliders 241 is opened on one side of the vertical plate 220. A guide shaft 261 is slidably connected inside another set of guide plates 260. The two ends of the guide shaft 261 are fixedly connected by a square plate 262. The bottom end of the square plate 262 is fixed to the top end of the workbench 100. The top end of the fixed plate 150 is provided with a movable groove 211 for the first clamping plate 210 to move. One end of the piston rod 2910 passes through the end of the round shaft 270 away from the guide plate 260. The top end of the fixed plate 150 is provided with a scale 352 on the side near the movable groove 311. The surface of the rope 360 ​​is provided with multiple sets of round rods 361 that change its extension direction, and a pull plate 380 is fixed to the end of the rope 360 ​​away from the sliding plate 340. The sliding plate 340 slides inside the groove 330.

[0039] By setting two sets of sliders 241 to cooperate with the slide groove 242, the second clamping plate 240 can be more stable when pressed down. By setting the guide shaft 261, the vertical plate 220 can be effectively prevented from shifting when moving, ensuring that it remains horizontal when cutting the gauze 180. The pull plate 380 makes it easy for the staff to move the positioning plate 320.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
