Description

Technical Field

[0001] This utility model relates to the field of rough edge cutting technology, and in particular to a laser cutting machine for rough edges of graphene cushions. Background Technology

[0002] Laser cutting machines utilize a high-energy-density laser beam to irradiate the rough edges of graphene cushions, causing the material to melt or vaporize instantly, thus achieving precise cutting and removing the burrs. During the cutting process, the laser beam's energy is highly concentrated, generating high temperatures in a very small area to locally process the material without causing significant thermal impact or damage to other parts of the cushion.

[0003] By comparing the burr removal mechanism of the sponge cutting machine with patent publication number CN218799826U, it can be seen that in this solution, the laser cutting head moves back and forth to cut the burrs at the end of the sponge, and then the servo motor drives the receiving impeller to rotate, collecting the cut burrs inside the receiving impeller, thus preventing the burrs from being left on the upper side of the material platform and affecting the cutting work of the sponge cutting machine. However, before cutting the burrs at the end of the sponge, the burrs cannot be flattened and tensioned, and the burrs may be in a loose state. As a result, after cutting the burrs, the cut end of the material may have uneven layers, requiring secondary processing, which reduces the cutting quality and efficiency. Utility Model Content

[0028] In this embodiment: the cleaning mechanism includes two symmetrical partitions 301 fixedly disposed on the front side of the base plate 100. A lead screw 303 is rotatably installed at the center of the partition 301. The lead screw 303 is threadedly connected to the partition 301. A limit plate 302 is rotatably disposed at one end of the two lead screws 303 that are close to each other. The limit plate 302 is slidably connected to the base plate 100. A rotating handle is fixed at the end of the lead screw 303 away from the limit plate 302. A support plate 304 is fixed between the rear sides of the two partitions 301. A fixing frame 305 is fixed at the lower end of the support plate 304. A scraper 306 is slidably installed inside the fixing frame 305. The scraper 306 is made of silicone material. A compression spring is connected between the scraper 306 and the fixing frame 305.

[0029] In this embodiment, the cutting mechanism includes a cutting structure for removing burrs from the end of the seat cushion and a conveying structure for conveying the seat cushion backward.

[0030] The conveying structure includes two symmetrical sliding frames 201 fixedly installed on the rear side of the base plate 100. A lifting plate 202 is slidably arranged between the two sliding frames 201. A hydraulic cylinder 203 is provided between the lifting plate 202 and the sliding frame 201. A conveying roller 204 is rotatably installed at the lower end of the lifting plate 202. Multiple anti-slip strips are distributed around the surface of the conveying roller 204. A conveying motor 205 is installed at the rotating end of the conveying roller 204. The output end of the conveying motor 205 is fixed to the rotating end of the conveying roller 204 through a coupling.

[0031] The cutting structure includes a connecting plate 206 located on the rear side of the sliding frame 201. There is a gap between the connecting plate 206 and the base plate 100. A cutting groove 207 is provided at the center of the connecting plate 206. A connecting frame 208 is provided above the cutting groove 207. The connecting frame 208 is fixed to the connecting plate 206. A slider 209 is slidably installed above the connecting frame 208. A cutting head 211 is installed at the lower end of the slider 209. A fixing rod 212 is fixed at the top of the slider 209. A locking nut 210 is threaded onto the fixing rod 212. A tensioning structure for locally tensioning the end of the seat cushion is provided below the cutting head 211.

[0032] The tensioning structure includes two sets of tensioning rollers 213 symmetrically arranged in the front-back direction in the cutting groove 207. Each set has three rollers, and the three tensioning rollers 213 in each set are distributed in the front-back direction. The tensioning rollers 213 are rotatably connected to the connecting plate 206. Spiral convex strips 214 made of rubber are fixed on the surface of the tensioning rollers 213. A pulley is fixed to the end of the tensioning rollers 213 away from the cutting groove 207. A drive belt connects the multiple pulleys. A fixing plate 215 is fixed to the end of the connecting plate 206 near the tensioning rollers 213. A rotary motor 216 is provided on the side wall of the fixed plate 215. The output end of the rotary motor 216 is fixed to the rotating end of the tension roller 213 through a coupling. Before cutting the rough edges of the seat cushion, the tensioning structure is used to flatten and tighten the seat cushion to both sides, so that the seat cushion is in a taut state. Then, the cutting structure is used to laser cut the end of the seat cushion, so that the end of the seat cushion is smoother and flatter after cutting, thereby avoiding unevenness at the end, improving the cutting quality and efficiency of the rough edges of the seat cushion, and avoiding secondary processing.

[0033] Working principle: First, the seat cushion to be processed is placed in front of the base plate 100. Then, the two lead screws 303 are turned to drive the two limiting plates 302 to move closer to each other and fit against the end of the seat cushion to limit the seat cushion. Then, the rear end of the seat cushion is pulled to the bottom of the conveyor roller 204. The hydraulic cylinder 203 is driven to move the lifting plate 202 down, which in turn moves the conveyor roller 204 down to fit against the upper surface of the seat cushion. Then, the conveyor motor 205 is driven to rotate the conveyor roller 204. The multiple anti-slip strips on the surface of the conveyor roller 204 rub against each other with the seat cushion, causing the seat cushion to move backward. During the movement of the seat cushion, the scraper 306 inside the fixed frame 305 scrapes off the dust remaining on the surface of the seat cushion.

[0034] When the seat cushion moves to the bottom of the connecting plate 206, the rotary motor 216 is started, and the transmission belt drives the multiple tension rollers 213 in both sets to rotate simultaneously. The spiral protrusions 214 on the surface of the tension rollers 213 rotate and rub against the seat cushion, thereby flattening and tensioning the end of the seat cushion to both sides, so that the end of the seat cushion is in a taut state. Then, the cutting head 211 is started to irradiate the burrs at the end of the seat cushion through the cutting groove 207, cutting off the burrs at the end. As a result, the end of the seat cushion after cutting is smoother and flatter, thus avoiding unevenness at the end, improving the cutting quality and efficiency of the burrs at the end of the seat cushion, and avoiding secondary processing.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
