Description

Technical Field

[0001] This invention relates to the field of fireproof curtain door processing technology, specifically to a cutting processing device for sewing fireproof curtain doors. Background Technology

[0002] Fireproof roller shutters can be classified into steel fireproof roller shutters, inorganic fabric fireproof roller shutters, and extra-grade fireproof roller shutters according to their materials. Among them, inorganic fabric fireproof roller shutters are widely used in various industrial, civil, and public buildings, such as office buildings, supermarkets, shopping malls, exhibition halls, underground garages, and entertainment venues. They provide fire separation in buildings, effectively preventing the spread of fire and smoke. When a fire occurs, the fireproof roller shutter can automatically descend under the control of the fire protection system, forming a solid fire barrier and controlling the fire within a certain range, providing valuable time for personnel evacuation and fire rescue.

[0003] Inorganic fireproof curtain doors are typically composed of materials such as fiberglass, graphite, and inorganic fibers. The stitching process during manufacturing is crucial, directly affecting the curtain's strength, fire resistance, flatness, and overall structural integrity. However, during stitching, excess material or irregularities may remain at the edges, resulting in uneven material distribution and poor edge stability. This makes the edges prone to damage or tearing during use, ultimately affecting the door's performance and lifespan.

[0004] Therefore, we propose a cutting and processing device for the sewing of fireproof curtain doors to solve the problems mentioned above. Summary of the Invention

[0023] Compared with the prior art, the beneficial effects of the present invention are: it facilitates clamping both ends of the inorganic fabric fireproof roller shutter door between the lower and upper push rollers, allowing the inorganic fabric fireproof roller shutter door to unfold to both sides. This facilitates the rapid cutting of excess material or irregular parts at the edges of the inorganic fabric fireproof roller shutter door, thereby improving the quality and performance of the fireproof roller shutter door seams. Furthermore, by adjusting the height between the lower and upper push rollers, it is convenient to cut the edges of fireproof roller shutter doors of different specifications, and also facilitates the adjustment of the longitudinal tension of the fireproof roller shutter door. Moreover, by setting guide rollers and pressing rollers, the cutting of the fireproof roller shutter door is made smoother. The specific details are as follows: 1. By setting up a spreading component, the ends of the inorganic fabric fireproof roller shutter are easily clamped between the lower and upper push rollers. The rotation of the transverse long gear drives the rotation of the lower and upper rotating shafts, which in turn drive the rotation of the lower and upper push rollers, thus spreading the inorganic fabric fireproof curtain door to both sides. This facilitates the spreading of the inorganic fabric fireproof curtain door on the conveyor belt before cutting, and allows for the rapid cutting of excess material or irregular parts at the edges of the inorganic fabric fireproof roller shutter door. The simultaneous use of the lower and upper push rollers ensures more even tension at both ends of the fireproof curtain door, preventing the fireproof curtain door from being cut at an angle. The flat edges reduce friction and resistance during sewing, making the stitches more even and firmly connected, which helps prevent damage or tearing of the edges during use, thereby improving the quality and performance of the fireproof curtain door sewing and extending the service life of the fireproof curtain door. 2. By setting a threaded rod in the middle of the movable bracket, the height of the upper connecting rod can be adjusted, thereby adjusting the height between the lower and upper pushing rollers. This allows for adjustment of the contact effect between the lower and upper pushing rollers and the top and bottom surfaces of the fireproof curtain door, facilitating the cutting of the edges of fireproof curtain doors of different specifications. Furthermore, the staggered arrangement of the lower and upper pushing rollers also facilitates the adjustment of the longitudinal tension of the fireproof curtain door, resulting in a smoother unfolding of the fireproof curtain door and higher precision in cutting. 3. By setting guide rollers and pressing rollers, the edges of the fireproof curtain door are stably spread out and pressed above the conveyor belt, so that the edges of the fireproof curtain door can fall stably between the cutting pad and the cutting blade, making the cutting of the fireproof curtain door smoother.

The setting of the transverse long gear 301 and the lower transmission gear 304 makes it easy to provide power to the lower push rollers 312 and the upper push rollers 325 without affecting the movement of the moving bracket 203. In addition, through the cooperation of the transmission belt 104, the conveyor belt 103, the lower push rollers 312 and the upper push rollers 325 can be started and stopped at the same time, so that the cutting device does not need to be controlled multiple times during use. Furthermore, the symmetrical setting of the lower push rollers 312 helps to reduce the influence of the fireproof curtain door's own weight on the pulling effect of the lower push rollers 312 on the end of the fireproof curtain door, thereby making the unfolding of the fireproof curtain door more stable.

[0029] Among them, a longitudinal bevel gear 316 is meshed with one side of the upper end of the lower connecting bevel gear 306.

The upper connecting bevel gear 320 is located at the lower end of the upper rotating gear 319. Through the arrangement of the longitudinal long gear 317, the sliding block 328, and the threaded rod 329, it is convenient to adjust the height of the upper connecting rod 327 without affecting the power supply to the upper push roller 325, thereby facilitating... This system allows for the laying out of fireproof curtain doors of varying thicknesses, facilitating the rapid trimming of excess material or irregular sections along the edges. This prepares the door for sewing. The use of longitudinal bevel gears 316 and 317 enables the simultaneous operation of the lower push roller 312 and upper push roller 325, resulting in more even tension at both ends of the fireproof curtain door and preventing tilting during cutting. The smooth cut edges reduce friction and resistance during sewing, leading to more even and secure stitching, preventing edge damage or tearing during use. Furthermore, the staggered lower push roller 312 and upper push roller 325 adjust the longitudinal tension of the fireproof curtain door, resulting in a smoother laying out before cutting.

At the end of 327 away from the transverse long gear 301, the clearance groove 401 is set in two sets. The guide roller 405 is slidably connected to the clearance groove 401 on the side near the transverse long gear 301. The side of the guide roller 405 near the upper connecting rod 327 is set as an arc-shaped cone.

The bottom surface of the cutting pad 408 is slidably connected to the top surface of the conveyor belt 103. One end of the cutting blade 409 passes through the connecting frame 407 and is fixedly connected to the output end of the cutting motor 410. The setting of the guide roller 405 and the pressing roller 406 facilitates the spreading effect at both ends of the fireproof curtain door, helps the fireproof curtain door to fit evenly with the conveyor belt 103, makes the cutting of the fireproof curtain door flatter, and makes the cutting accuracy of the fireproof curtain door higher.

[0031] Working principle: such as Figures 1-9 As shown, when using this device, firstly, the fireproof curtain door to be processed is placed above the fixed bracket 201. Then, by controlling the limit motor 204, the limit motor 204 drives the bidirectional screw 202 to retract the moving bracket 203, so that the moving bracket 203 fits against the edge of the fireproof curtain door. The fireproof curtain door is then passed between the lower push roller 312 and the upper push roller 325, so that the lower torsion spring 310 and the upper torsion spring 324 are tightened. Subsequently, the fireproof curtain door is passed through the lower end of the guide roller 405 and the pressing roller 406, and then passes through the middle of the cutting pad 408 and the cutting blade 409.

[0032] Secondly, by controlling the lifting motor 330, the lifting motor 330 drives the threaded rod 329 to rotate, thereby causing the threaded rod 329 to drive the sliding block 328 at the end of the upper connecting rod 327 to rise and fall on one side of the moving bracket 203. At this time, the upper transmission gear 318 in the middle of the upper connecting rod 327 slides on the longitudinal long gear 317. At the same time, the lifting shaft 404 slides in the relief groove 401, causing the compression spring 402 to move in the relief groove 401 through the compression plate 403, and causing the connecting frame 407 to drive the cutting pad 408 and the cutting blade 409 to descend.

[0033] Next, the power supply of the power motor 302 is turned on, causing the power motor 302 to drive the transverse long gear 301 to rotate. The transverse long gear 301 drives the lower transmission gear 304 in the middle of the lower connecting rod 303 to rotate, and the lower transmission gear 304 drives the lower rotating gear 305 to rotate. At this time, the lower connecting bevel gear 306 drives the lower rotating shaft 308 to rotate through the lower transmission bevel gear 307. Subsequently, the lower rotating shaft 308 drives the lower rotating rod 314 in the middle of the U-shaped frame 311 to rotate through the lower power belt 315. This causes the lower rotating rod 314 to drive the lower push roller 312 at the end of the lower support rod 309 to rotate through the lower transmission belt 313, thereby enabling the bottom surface of the fireproof curtain door to unfold to both sides.

[0034] At the same time, the upper end of the lower connecting bevel gear 306 drives the longitudinal long gear 317 to rotate through the longitudinal bevel gear 316, which in turn drives the upper transmission gear 318 to rotate, and the upper transmission gear 318 drives the upper rotating gear 319 to rotate. At this time, the upper connecting bevel gear 320 drives the upper rotating shaft 322 to rotate through the upper transmission bevel gear 321, which in turn drives the upper rotating shaft 322 to rotate through the upper power belt 326, which in turn drives the upper push roller 325 in the middle of the upper support rod 323 to rotate, and the upper push roller 325 drives the top surface of the fireproof curtain door to unfold to both ends.

[0035] Finally, the two ends of the unfolded fireproof curtain door are guided by guide rollers 405 to unfold the fireproof curtain door. At the same time, the transverse long gear 301 drives the conveyor roller 102 to rotate through the transmission belt 103, so that the conveyor roller 102 drives the conveyor belt 104 to rotate on the conveyor support 101. Under the pressure of the pressing roller 406, the fireproof curtain door is moved. Then, the cutting motor 410 drives the cutting blade 409 to rotate, so as to cut the edge of the fireproof curtain door.
