Description

Technical Field

[0001] The invention relates to the field of laser cutting of plush cloth, and in particular to a laser cutting bed for processing plush cloth. Background Art

[0002] Laser cutting machine, also known as computer laser cutting machine, is a device that is controlled by a computer to realize material cutting. Laser cutting machine uses the characteristics of good directivity, high beam power and thin beam of laser beam to focus the laser beam into a light spot with a small diameter but high light energy density through an optical focusing device. When this beam of light irradiates the cutting point on the surface of the material, the light energy is absorbed by the material, causing the temperature of the material at the irradiation point to rise sharply and vaporize quickly, forming a hole the size of the light spot. According to the cutting requirements, the laser beam and the material are continuously moved relative to each other, so that a cutting path can be formed on the material, thereby completing the cutting process.

[0003] The patent application with announcement number CN220880976U discloses a safe laser cutting bed, including a cutting bed base, a laser cutting machine body and a hydraulic rod body. The top surface of the cutting bed base is provided with a steel wire mesh, and the top surface of the cutting bed base is fixedly connected with support columns on all sides. The safe laser cutting bed, through the setting of the smoke extinguishing adsorption component and the smoke alarm component, extracts the smoke extinguishing adsorption component, and adds appropriate water inside the water storage box. When the laser cutting bed is working, the fire stains will fall into the water in the water storage box through the steel wire mesh, so that the fire stains and smoke are extinguished and adsorbed. When a fire occurs, a large amount of smoke will be generated, which will be detected by the point-type photoelectric smoke fire detector body, processed by the fire alarm controller body, and the fire sound and light alarm body will be triggered to alarm, thereby increasing the fire fighting function of the laser cutting bed, avoiding the occurrence of fire, and improving the safety of the laser cutting bed.

[0004] During use, the existing laser cutting bed needs to cut the cloth to be cut into corresponding sizes according to the size of the cutting bed, and then cover it to the processing position of the cutting bed and fix it. After the cutting process, the waste cloth and the processed products need to be collected before the next cutting can be carried out. Therefore, this cutting method greatly reduces the cutting efficiency. In addition, during the cutting process, the connection between the cut cloths is lost, which makes it easy for the cloth to wrinkle during subsequent cutting, thereby affecting the cutting accuracy.

[0022] The positioning assembly 002 disposed above the base 001 includes a sliding frame 201, the sliding frame 201 is installed above the base 001, and the sliding frame 201 is located between the two groups of conveying rollers 101, a connecting plate 202 is arranged above the inside of the sliding frame 201, a hydraulic rod 205 is installed below the connecting plate 202, a lower pressing seat 206 is installed at the output end of the hydraulic rod 205, and a guide rod 207 is installed between the connecting plate 202 and the lower pressing seat 206, and the lower pressing seat 206 is fixedly connected to the lower pressing plate 102; The lower pressing seat 206 can be moved downward by the hydraulic rod 205, and the guide rod 207 can make the lower pressing seat 206 run more smoothly during the downward movement.

[0023] The flattening assembly 003 arranged above the sliding frame 201 includes a connecting frame 301, which is arranged at the lower part of the sliding frame 201, and the connection method between the connecting frame 301 and the sliding frame 201 is the same as the connection method between the sliding frame 201 and the base 001. A fixing frame 302 is installed above the connecting frame 301, and a placing frame 304 is installed inside the connecting frame 301. A hydraulic rod 2 305 is installed above the placing frame 304, and a docking cylinder 306 is installed at the output end of the hydraulic rod 2 305. The outer side of the docking cylinder 306 is rotatably connected to four groups of connecting arms 311 in an annular distribution. A connecting frame 313 is installed on one side of the connecting arm 311, and a roller 314 is rotatably connected inside the connecting frame 313. The docking tube 306 can be moved upward by the hydraulic rod 305, so that the connecting arm 311 drives the connecting frame 313 to unfold, so that the roller 314 flattens the cloth.

[0024] The moving component 004 arranged in the sliding frame 201 includes a rotating shaft 401, which is rotatably connected to the bottom of the connecting plate 202, and two groups of rotating shafts 401 are symmetrically arranged under the connecting plate 202, and the winding reels 402 are symmetrically sleeved and fixed on the two groups of rotating shafts 401. A servo motor 403 is axially connected to one side of one group of rotating shafts 401, and the servo motor 403 is fixedly connected to the connecting plate 202.

[0025] The servo motor 403 can drive the rotating shaft 401 to rotate, so that the rotating shaft 401 drives the winding drum 402 to rotate.

[0026] Furthermore, in the above structure, the positioning assembly 002 also includes a sliding seat 203, which is symmetrically installed above the connecting plate 202, a sliding rod 204 is installed in the sliding frame 201, and the sliding rod 204 is sleeved with the sliding seat 203, and the sliding seat 203 is slidably connected with the sliding frame 201.

[0027] The sliding seat 203 slides along the sliding rod 204 , so that the connecting plate 202 can slide under the sliding frame 201 .

[0028] Furthermore, in the above structure, a plurality of docking rods 209 are connected in a rectangular array at the lower edge of the lower pressure plate 102, a fixed frame 208 is installed below each group of docking rods 209, a spring 210 is sleeved on each group of docking rods 209, and both sides of the spring 210 are respectively fitted with the upper part of the fixed frame 208 and the lower part of the lower pressure plate 102.

[0029] The position of the fixing frame 208 can be maintained by the spring 1 210, and as the lower pressing seat 206 moves downward, the fixing frame 208 fits against the upper part of the fixing frame 302, and the spring 1 210 is squeezed, thereby completing the partial fixation of the cloth.

[0030] Furthermore, in the above structure, the flattening component 003 also includes a through slot 303, which is opened above the inner wall of the fixing frame 302, and a push rod 307 is slidably connected in the docking tube 306, and a spring 2 308 is fitted between the push rod 307 and the docking tube 306.

[0031] The second spring 308 can enable the push rod 307 to push the docking sleeve 306 to move upward, and after the push rod 307 stops moving, the docking sleeve 306 can still move upward, thereby avoiding excessive squeezing of the second hydraulic rod 305.

[0032] Furthermore, in the above structure, a fixing plate 309 is installed above the push rod 307 , a guide frame 310 is sleeved and fixed at the edge of the fixing plate 309 , and the guide frame 310 is slidably connected to the inside of the through slot 303 .

[0033] The guide frame 310 on the fixing plate 309 slides along the through slot 303, so that the fixing plate 309 moves to above the fixing frame 302, so as to fit the fixed part of the cloth, thereby achieving a flattening effect.

[0034] Furthermore, in the above structure, a sliding cavity 312 is opened on one side of the connecting arm 311 , a positioning rod 317 is installed below the fixing frame 302 , and the positioning rod 317 is connected to the sliding cavity 312 through the positioning rod 317 .

[0035] Through the cooperation between the positioning rod 317 and the sliding cavity 312 , the connecting arm 311 can be limited in position during the upward movement of the docking tube 306 , so that the connecting arm 311 can be smoothly deployed.

[0036] Furthermore, in the above structure, guide seats 315 are symmetrically installed on the outer side of the connection frame 313 , and slide rails 316 are symmetrically installed on one side of the fixing frame 302 , and the slide rails 316 are slidably connected to the corresponding guide seats 315 .

[0037] The connection frame 313 moves to both sides through the cooperation between the slide rail 316 and the guide seat 315 .

[0038] Furthermore, in the above structure, the moving component 004 also includes a bevel gear 404, which is sleeved and fixed on the two sets of rotating shafts 401, and a double-headed bevel gear shaft 405 is rotatably connected below the connecting plate 202, and the two sides of the double-headed bevel gear shaft 405 are respectively engaged with the two sets of bevel gears 404.

[0039] Through the cooperation between the double-headed bevel gear shaft 405 and the two sets of bevel gears 404, when one set of rotating shafts 401 rotates, the other set of rotating shafts 401 can be driven to rotate.

[0040] Furthermore, in the above structure, each group of winding drums 402 is wound with a steel cable 406 , and the steel cable 406 in the winding drums 402 on the same group of rotating shafts 401 passes through the sliding frame 201 and is fixedly connected to the connecting frame 301 below.

[0041] When the wire rope 406 is wound by rotating the winding drum 402 on one side, the winding drum 402 on the opposite side can release the wire rope 406 with the cooperation of the double-headed bevel gear shaft 405 and the two sets of bevel gears 404, thereby realizing the synchronous movement of the connecting frame 301 and the connecting plate 202, and the connection methods of the wire ropes 406 on both sides are the same.

[0042] like Figure 1-9 As shown, by passing the cloth through the two sets of conveying rollers 101, the servo motor 403 drives the rotating shaft 401 to rotate, so that the rotating shaft 401 drives the winding drum 402 to rotate, and the double-headed bevel gear shaft 405 drives the two sets of winding drums 402 to rotate in opposite directions through the two sets of bevel gears 404. At this time, the steel cable 406 can drive the connecting plate 202 and the connecting frame 301 to move to the corresponding cutting position. At this time, the hydraulic rod 305 drives the docking tube 306 to move upward, so that the push rod 307 drives the fixed plate 309 to fit under the cloth.

[0043] At the same time, the connecting arm 311 drives the connecting frame 313 and the roller 314 to expand outward and fit under the cloth. At this time, the hydraulic rod 205 moves the lower pressing seat 206, so that the fixed frame 208 moves downward and fits to the position above the cloth, so that the spring 210 is squeezed, and at the same time, the laser cutting seat 104 is driven to move through the XY axis sliding track 103 to cut the cloth. After the processing is completed, the other positions of the cloth are cut through the above-mentioned actions, and the cloth is transported by two sets of conveying rollers 101, so as to complete the continuous processing operation of the cloth, and long-distance cutting can be performed. Through this structure, it is possible to achieve that there is no need for manual fixing and collection of the cloth before and after cutting, thereby realizing continuous cutting of the cloth, thereby improving the processing efficiency of the cloth.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
