[0061] Example 1

[0062] like Figures 1-27 As shown, a composite flame-retardant roller blind fabric manufacturing system includes a conveying mechanism 2 mounted on a frame 1, and a fabric laying mechanism 3, a forming mechanism 4, a sewing mechanism 5, and a winding mechanism 6 sequentially mounted on the frame 1 along the transmission direction of the conveying mechanism 2.

[0063] The forming mechanism 4 includes a pressing component 41 mounted on the frame 1 for pressing the intermediate fabric into a wavy shape, an injection component 42 mounted on the pressing component 41 for injecting flame-retardant particles into the gaps of the wavy intermediate fabric, a segmentation component 43 mounted on the pressing component 41 for dividing the gaps of the wavy intermediate fabric into several independent spaces, and an adhesive component 44 mounted on the pressing component 41 for bonding the base fabric 7, the wavy intermediate fabric 8, and the cover fabric 9 together.

[0064] The intermediate cloth is corrugated and is bonded between the base cloth and the cover cloth to form a composite fabric. Adjacent two valleys and adjacent two peaks of the corrugated intermediate cloth form gaps with the base cloth and the cover cloth respectively. The gaps are separated into a plurality of independent spaces by the strip-shaped steel sheet 10 along the axis direction of the gaps while the flame-retardant particles 11 are injected into the gaps. The flame-retardant particles are distributed in each independent space. The cloth is uniform and not easy to run. The composite fabric structure is stable and not easy to wrinkle and deform.

[0065] It is worth mentioning that the base cloth 7 is made of wear-resistant material, the corrugated intermediate cloth 8 is made of flame-retardant material, and the cover cloth 9 is made of heat-insulating material. The three are bonded to form a composite flame-retardant roller shutter fabric.

[0066] In the embodiment, the laying mechanism 3 and the forming mechanism 4 cooperate. On the one hand, the intermediate flame-retardant layer of the composite fabric is processed into a corrugated shape. Compared with the planar flame-retardant layer, the corrugated flame-retardant layer is longer in unit length, more in amount, and better in flame-retardant effect. The gaps in the corrugated flame-retardant layer are filled with flame-retardant particles, which further improves the flame-retardant effect of the composite fabric. On the other hand, the gaps in the corrugated flame-retardant layer are separated into a plurality of independent spaces by the strip-shaped steel sheet. The flame-retardant particles are distributed in each independent space. The cloth is uniform and not easy to run. The strip-shaped steel sheet and the corrugated flame-retardant layer are interlaced longitudinally and transversely, so that the composite fabric structure is stable and not easy to wrinkle. After burning, the composite fabric is not easy to deform and leak.

[0067] In detail, first, the conveying belt carries the carrier 21 to the position of the first fabric laying assembly 31 and continues to move forward, the first fabric laying assembly 31 automatically releases a certain length of base fabric and lays it on the carrier 21, and the vacuum suction hole 22 fixes the base fabric on the carrier 21; then, the conveying belt carries the carrier 21 to the position of the profiling assembly 41 and stops, the lower die pipe 4115 of the lower die unit 411 is lowered from the middle to the two sides in turn and presses on the base fabric, and the base fabric is pulled tight from the middle to the two sides in turn, the second fabric laying assembly 32 releases a certain length of middle fabric and lays it on the lower die pipe 4115, and the middle fabric is coated with strip-shaped hot melt glue on the upper and lower surfaces in an interlaced manner, the upper die pipe 4126 of the upper die unit 412 is lowered from the middle to the two sides in turn and presses on the middle fabric, and continues to be lowered into the gap between the two adjacent lower die pipes 4115, so as to press the strip-shaped hot melt glue on the lower surface of the middle fabric on the base fabric to form a wave trough, and the lower die pipe 4115 props up the strip-shaped hot melt glue on the upper surface of the middle fabric to form a wave peak, so as to press the middle fabric into a wave shape; then, the third fabric laying assembly 33 releases a certain length of cover fabric and lays it on the wave-shaped middle fabric, the profiling plate 443 is lowered and presses on the cover fabric, the first electric heating strip 441 at the top of the lower die pipe 4115 and the second electric heating strip 442 at the bottom of the upper die pipe 4126 heat the strip-shaped hot melt glue at the wave peak and the wave trough of the wave-shaped middle fabric at the same time, the wave peak of the wave-shaped middle fabric is bonded to the lower surface of the cover fabric, and the wave trough of the wave-shaped middle fabric is bonded to the upper surface of the base fabric, and the composite profile fabric is bonded and formed; then, the first pushing unit 421 and the second pushing unit 422 simultaneously extract the lower die pipe 4115 and the upper die pipe 4126, so that the fire-retardant particles in the lower die pipe 4115 and the upper die pipe 4126 are left in the gap of the wave-shaped middle fabric, in the process of intermittently extracting the lower die pipe 4115 and the upper die pipe 4126, the strip-shaped steel sheet penetrates through the gap of the wave-shaped middle fabric along the pipe opening of the lower die pipe 4115 and the upper die pipe 4126 in a transverse direction, and the gap is divided into a plurality of groups of independent spaces in turn, and the fire-retardant particles are distributed in each independent space; then, the conveying belt carries the carrier 21 to the position of the edge sewing mechanism 5 and stops, the edge sewing mechanism 5 sews and seals the four edges of the composite profile fabric in turn; then, the conveying belt carries the carrier 21 to the position of the winding mechanism 6 and stops, first, the quick-drying glue is coated on the composite profile fabric, then the winding drum is pushed horizontally along the upper surface of the composite profile fabric, the winding drum is bonded to one side of the composite profile fabric through the quick-drying glue, and then the winding drum rolls to wind the composite profile fabric, and finally the output is obtained.

[0069] It should be noted that the depth of the bearing seat 21 is less than the thickness of the base cloth 7, that is, after the base cloth 7 is laid on the bearing seat 21, the upper surface of the base cloth 7 is higher than the upper surface of the bearing seat 21, so that the lower mold tube 4115 can be pressed against the upper surface of the base cloth 7;

[0070] The base cloth laying mechanism 3 comprises a first base cloth laying assembly 31 arranged on the frame 1 and used for laying the base cloth on the bearing seat 21, a second base cloth laying assembly 32 arranged on the profiling assembly 41 and used for laying the intermediate cloth on the base cloth, and a third base cloth laying assembly 33 arranged on the profiling assembly 41 and used for laying the cover cloth on the intermediate cloth.

[0071] The first base cloth laying assembly 31 comprises an L-shaped hanger 311 arranged on the frame 1, a base cloth roll 312 rotatably arranged on the L-shaped hanger 311, a base cloth driving roller 313 rotatably arranged on the L-shaped hanger 311 and used for driving the base cloth to be conveyed forward, a first gear 314 arranged on the L-shaped hanger 311 and synchronously rotated with the base cloth driving roller 313 through a synchronous belt, a first rack 315 arranged on the outer wall of the bearing seat 21 and used for driving the first gear 314, a first cutter 316 arranged on the L-shaped hanger 311 in a lifting manner, a first elastic member 317 arranged between the end of the first cutter 316 and the L-shaped hanger 311, an L-shaped extension rod 318 arranged at the end of the first cutter 316 and having an end penetrating through the L-shaped hanger 311, and a limiting track 319 arranged on the side of the first rack 315 and used for driving the L-shaped extension rod 318 to lift the first cutter 316.

[0072] In the embodiment, the conveying mechanism 2 and the first base cloth laying assembly 31 are cooperated to automatically release a certain length of the base cloth to be laid on the bearing seat 21.

[0073] In detail, after the conveying belt moves the bearing seat 21 to the position of the first base cloth laying assembly 31 and continues to advance, the limiting tracks 319 on the two sides of the bearing seat 21 drive the L-shaped extension rod 318 to lift the first cutter 316, then the first racks 315 on the two sides of the bearing seat 21 drive the first gears 314 to rotate the base cloth driving roller 313 through the synchronous belt, the base cloth driving roller 313 conveys the base cloth on the base cloth roll 312 forward, the base cloth is synchronously laid on the bearing seat 21, the vacuum suction holes 22 on the two rear corners of the bearing seat 21 first fix the front end of the base cloth, when the bearing seat 21 continues to advance to the position away from the first base cloth laying assembly 31, the limiting tracks 319 are separated from the L-shaped extension rod 318, the first cutter 316 is lowered to cut the base cloth under the elastic force of the first elastic member 317, and at the same time, the first racks 315 are separated from the first gears 314, the base cloth driving roller 313 stops conveying the base cloth, and then the vacuum suction holes 22 on the two rear corners of the bearing seat 21 fix the rear end of the cut base cloth.

[0074] Further, asFigures 7-15 As shown, the profiling assembly 41 comprises a lower die unit 411 arranged on the frame 1 for supporting the crest forming of the wavy intermediate fabric and an upper die unit 412 arranged on the frame 1 for supporting the trough forming of the wavy intermediate fabric;

[0075] The lower die unit 411 comprises a first hydraulic component 4111 arranged on the frame 1, a hanger plate 4112 arranged on the output shaft of the first hydraulic component 4111, a frame 4114 arranged at a position below the hanger plate 4112 through a second elastic component 4113, a plurality of groups of lower die pipes 4115 arranged inside the frame 4114 in a V-shaped distribution and having one end open, two groups of chain plates 4116 symmetrically arranged and respectively hingedly sleeved at both ends of adjacent two lower die pipes 4115, a horizontal rod 4117 hingedly arranged on one of the chain plates 4116 and having its end penetrating the side wall of the frame 4114, and a third elastic component arranged between the end of the horizontal rod 4117 and the outer wall of the frame 4114;

[0076] It should be noted that the number of lower die pipes 4115 is even, i.e., the bottom of the V-shaped structure is two lower die pipes 4115, which facilitates the arrangement of the lower die pipes 4115;

[0077] It is worth mentioning that the adjacent two chain plates 4116 are in close contact with each other and are rotationally connected through a limiting groove and cannot be separated;

[0078] The upper die unit 412 comprises an outer edge plate 4121 arranged at a position below the hanger plate 4112 through a hanger rod, two groups of strip plates 4122 respectively arranged at both ends of the outer edge plate 4121, a plurality of groups of hanging rods 4123 penetrating and arranged in a lifting manner on the strip plates 4122, a fourth elastic component 4124 arranged between the upper end of the hanging rod 4123 and the strip plate 4122, a hanging ring 4125 arranged at the lower end of the hanging rod 4123, a plurality of groups of upper die pipes 4126 respectively slidably sleeved on the opposite two hanging rings 4125 and arranged in a V-shaped distribution, and an avoiding groove 4127 opened in the chain plate 4116 for avoiding the upper die pipe 4126, the upper die pipe 4126 being respectively arranged above the gap between adjacent two lower die pipes 4115;

[0079] It should be noted that the gap width between adjacent two lower die pipes 4115 is greater than the cross-sectional circular diameter of the upper die pipe 4126, so as to ensure that the hanging rod 4123 can carry the upper die pipe 4126 to descend into the gap between adjacent two lower die pipes 4115, and the avoiding groove 4127 ensures that the upper die pipe 4126 can descend to the same horizontal plane as the lower die pipe 4115;

[0080] It should be further noted that the number of upper die pipes 4126 is odd, i.e., the bottom of the V-shaped structure is a single upper die pipe 4126, which facilitates the cooperation of the upper die pipe 4126 and the lower die pipe 4115.

[0096] The segmented assembly 43 comprises two groups of side plates 431 symmetrically arranged on both sides of the profiling plate 443, a sliding hole 432 opened on the side plate 431, a sliding block 433 slidingly arranged inside the sliding hole 432, a mounting rack 434 arranged on one of the sliding blocks 433, a strip steel sheet roll 435 rotationally arranged on the mounting rack 434, two groups of straightening rollers 436 arranged on the mounting rack 434 and used for straightening the strip steel sheet, a first stepping motor arranged on the mounting rack 434 and used for driving the straightening rollers 436, a strip-shaped through hole opened on one of the sliding blocks 433 and used for allowing the strip steel sheet to pass through, a seventh hydraulic component 437 arranged on one of the sliding blocks 433, a V-shaped cutter 438 arranged on the output shaft of the seventh hydraulic component 437 and used for cutting the strip steel sheet, a baffle 439 arranged on one of the sliding blocks 433 and matched with the V-shaped cutter 438, two groups of bending plates 4391 respectively arranged on the two sliding blocks 433 and used for bending the two ends of the cut strip steel sheet, and two groups of synchronous rods 4392 respectively arranged between the two sliding blocks 433 and the second strip pushing unit 4223;

[0097] It is to be noted that the V-shaped cutter 438 can cut the cut head of the strip steel sheet into a V-shaped head, and the V-shaped strip steel sheet cut head is beneficial to penetrating through the wave-shaped intermediate cloth and will not cause the wave-shaped intermediate cloth to be deformed, and the strip steel sheet will not be bent;

[0098] It is to be noted that the strip steel sheet roll 435 moves synchronously with the first and second pushing units 421 and 422 through the synchronous rods 4392, so that the strip steel sheet will penetrate through the wave-shaped intermediate cloth along the pipe openings of the lower die pipe 4115 and upper die pipe 4126 after the first and second pushing units 421 and 422 stop working each time, and the pipe openings of the lower die pipe 4115 and upper die pipe 4126 have a transverse supporting force on the wave-shaped intermediate cloth in the advancing direction of the strip steel sheet, so that the strip steel sheet is more easily penetrated through the wave-shaped intermediate cloth and will not be bent and deformed;

[0099] It should be noted that after the strip-shaped steel sheet completely penetrates the entire wave-shaped intermediate cloth, the V-shaped cutter 438 cuts the strip-shaped steel sheet, and the two cut-off heads of the strip-shaped steel sheet are left outside the wave-shaped intermediate cloth. The second material pushing unit 422 again drives the two sliding blocks 433 to move through the synchronous rod 4392, and the bending plates 4391 of the two sliding blocks 433 bend the two cut-off heads of the strip-shaped steel sheet left outside the wave-shaped intermediate cloth, preventing the strip-shaped steel sheet from separating from the wave-shaped intermediate cloth and improving the stability of the strip-shaped steel sheet insertion installation.

[0100] In the present embodiment, through the cooperation of the injection assembly 42 and the segmentation assembly 43, on the one hand, the lower mold pipe 4115 and the upper mold pipe 4126 can be simultaneously separated from the wave-shaped intermediate cloth, and the fireproof particles are left to fill the gaps of the wave-shaped intermediate cloth, so that the composite fireproof fabric is filled; on the other hand, during the process of separating the lower mold pipe 4115 and the upper mold pipe 4126, the strip-shaped steel sheet is segmented and inserted into the wave-shaped intermediate cloth, and the two cut-off heads of the strip-shaped steel sheet left outside the wave-shaped intermediate cloth are bent, preventing the strip-shaped steel sheet from separating from the wave-shaped intermediate cloth and improving the stability of the composite fabric.

[0101] In detail, when the upper die tube 4126 is lowered and pressed on the middle fabric, the second push block 4226 of the second push unit 422 is also lowered and pressed on the inner wall of the frame 4114. After the composite fabric is formed, the second hydraulic component 4211 of the first push unit 421 and the third hydraulic component 4222 of the second push unit 422 drive the first push rod 4212 and the second push rod 4223 to move synchronously. The first push rod 4212 drives the lower die tube 4115 to pull out through the lower extension rod 4215, and the second push rod 4223 drives the upper die tube 4126 to pull out through the upper extension rod 4224. The first push block and the second push block 4226 are both pressed on the inner wall of the frame 4114, forcing the first push rod 4217 to move relative to the first push block 4216 inside the lower die tube 4115, and the second push rod 4225 to move relative to the second push block inside the upper die tube 4126. Thus, the fire-retardant particles in the upper die tube 4126 and the lower die tube 4115 are synchronously discharged and left in the gaps of the wavy middle fabric. The first push unit 421 and the second push unit 422 work intermittently and synchronously. During the time when the first push unit 421 and the second push unit 422 stop working, the straightening roller 436 of the segmenting assembly 43 outputs and straightens the steel strips, so that the steel strips are inserted into the wavy middle fabric. The seventh hydraulic component 437 drives the V-shaped cutter 438 to cut the steel strips. The first push unit 421 and the second push unit 422 continue to work. The second push rod 4223 moves through the two sliding blocks 433 of the synchronous rod 4392. The two sliding blocks 433 of the bending plate 4391 bend the two cut ends of the steel strips outside the wavy middle fabric, thereby segmenting the gaps of the wavy middle fabric one by one, until the lower die tube 4115 and the upper die tube 4126 completely separate from the wavy middle fabric. Finally, the first hydraulic component 4111 of the lower die unit 411 drives the lifting plate 4112 to rise and reset. The profiled plate 443 of the bonding assembly 44 rises and resets first, and then the upper die tube 4126 rises and resets. The lower die tube 4115 rises and resets, the first push unit 421 drives the lower die tube 4115 to horizontally reset, the second push unit 422 drives the upper die tube 4126 to horizontally reset, and finally, the tenth hydraulic component 4235 of the feeding unit 423 drives the feeding rod 4236 to push the fire-retardant particles in the feeding tube 4232 into the lower die tube 4115 and the upper die tube 4126, for use in the next work.

[0103] It should be noted that the structure and function of the sewing head 58 are both prior art, which will not be described here again. The four edges of the composite fabric are sewn and sealed in sequence.

[0104] It is worth mentioning that the thread used on the sewing head 58 is made of flame-retardant material, the composite fabric is pre-formed by using strip-shaped hot melt adhesive, the sewing head 58 uses flame-retardant thread to sew the base cloth, the intermediate cloth and the cover cloth together along the crests and troughs of the wavy intermediate cloth, which is the secondary forming, avoiding the melting of the strip-shaped hot melt adhesive, causing the cover cloth and the base cloth to separate from the wavy intermediate cloth.

[0105] In this embodiment, through the edge sewing mechanism 5 arranged, the four edges of the composite fabric are sequentially sewn and sealed, and then the base cloth, the intermediate cloth and the cover cloth are sequentially sewn together along the crests and troughs of the wavy intermediate cloth, preventing the strip-shaped hot melt adhesive of the wavy intermediate cloth from melting after the composite fabric is burned, causing the cover cloth and the base cloth to separate from the wavy intermediate cloth.

[0106] In detail, after the conveying belt carrying the carrier 21 moves to the position of the edge sewing mechanism 5 and stops, the first lead screw 53 drives the sewing head 58 to move horizontally left and right, and the second lead screw 56 drives the sewing head 58 to move horizontally forward and backward, so that the sewing head 58 uses flame-retardant thread to sequentially sew and seal the four edges of the composite fabric, and then sequentially sews the base cloth, the intermediate cloth and the cover cloth together along the crests and troughs of the wavy intermediate cloth.

[0107] Further, as shown in FIG. 6, the edge sewing mechanism 5 comprises a first stepper motor 55 arranged on the side wall of the hanging frame 52 and used for driving the first lead screws 53, a second stepper motor 56 arranged between the two first threaded blocks 54 and used for driving the second lead screw 56, and a third stepper motor arranged on the first threaded block 54 and used for driving the second lead screw 56. Figure 3 and Figures 25-27As shown, the winding mechanism 6 includes an applicator wheel 61 mounted on the frame 1 via a bracket for applying strip-shaped quick-drying adhesive to the cover cloth; a storage box 62 mounted on the frame 1 and containing a roll; two sets of L-shaped output holes 63 symmetrically opened on both sides of the storage box 62; a lifting plate 64 lifted and lowered inside the storage box 62 via a seventh elastic element for pushing the roll upward; a vertical plate 65 mounted on the outer wall of the storage box 62 via a connecting plate; two sets of ninth hydraulic components 66 symmetrically arranged on the vertical plate 65; a mounting post 67 mounted on the output shaft of the ninth hydraulic component 66; a lifting groove opened on the mounting post 67; a lifting block 68 slidably disposed inside the lifting groove; an eighth elastic element disposed between the lifting block 68 and the end of the lifting groove; a second electric gripper 69 mounted on the lifting block 68 for clamping the rotating shaft of the roll; a height limiting plate 691 disposed at the bottom of the mounting post 67 for limiting the rise of the roll below; and a winding box 692 mounted on the frame 1.

[0108] It should be noted that the function of the height limit plate 691 is to restrict the rise of the drum in the lower storage box 62 during the process of the second electric gripper 69 pushing the uppermost drum of the storage box 62, so as to facilitate the smooth return and reset of the second electric gripper 69.

[0109] It is worth mentioning that during the process of the second electric gripper 69 pushing the composite fabric on the roll winding carrier 21, as the roll winding up more composite fabric, the second electric gripper 69 will drive the roll winding up with the lifting block 68 to ensure that the roll winding up the composite fabric smoothly.

[0110] In this embodiment, the winding mechanism 6 can automatically wind up the composite fabric and output the collected material.

[0111] In detail, when the conveyor belt carrying the carrier 21 moves to the position of the coating roller 61, the coating roller 61 applies quick-drying adhesive to the composite fabric. The conveyor belt, carrying the carrier 21, quickly moves to the position of the winding mechanism 6 and then stops. The ninth hydraulic component 66 drives the mounting column 67 to move the second electric gripper 69, causing the second electric gripper 69 to grasp the shaft of the drum and push the drum onto the composite fabric of the carrier 21 to roll. The drum adheres to one side of the composite fabric with the quick-drying adhesive, and then the composite fabric is rolled up and finally output into the receiving box 692.
