Technical Field

[0001] The invention belongs to the technical field of cloth processing, and in particular relates to a printing and dyeing device for antibacterial cloth and a production process thereof. Background Art

[0002] Fabric printing and dyeing is a way of processing fabrics. It is a general term for fabric pretreatment, dyeing, printing, finishing, washing and drying. Among them, fabrics need to go through a dyeing process to be able to present different colors. In the dyeing process of ordinary fabrics, the dye is added to the dye vat and the fabric is immersed in the dye vat for dyeing. The dyeing of antibacterial fabrics requires the addition of antibacterial agents on the basis of ordinary dyeing to make the fabric antibacterial.

[0003] In order to improve the uniform dyeing adhesion of the fabric to the dye slurry and antibacterial agent, the dye vat needs to be stirred to keep the dye slurry and antibacterial agent evenly mixed during the dyeing process. At the same time, in order to facilitate the squeezing of the dyed fabric, we proposed an antibacterial fabric printing and dyeing equipment and its production process. Summary of the invention

[0004] The purpose of the present invention is to provide a printing and dyeing device for antibacterial cloth and a production process thereof, which can stir and mix the dye slurry and antibacterial agent in the dyeing vat and squeeze water from the dyed cloth.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows: A printing and dyeing device for antibacterial fabrics, comprising a dyeing vat, a recovery vat being integrally fixed to one lateral side of the dyeing vat, a base being provided at the bottom of the dyeing vat and the recovery vat, first guide rollers being installed at both lateral sides of the inside of the dyeing vat, and second guide rollers being mounted at both lateral sides of the top of the dyeing vat, first vertical rotating rods being rotatably connected to both upper and lower sides of the middle of the dyeing vat, and multiple groups of stirring blades being installed at the sides of the two first vertical rotating rods; A second vertical rotating rod is rotatably connected to one side of the middle longitudinal part of the dye vat, the first vertical rotating rod and the second vertical rotating rod on the upper and lower sides are connected by a pulley and a belt transmission, a first bevel tooth is fixed on the top of the second vertical rotating rod, the dye vat is also rotatably connected to the first longitudinal rotating rod, and one end of the first longitudinal rotating rod is fixedly connected to a second bevel tooth meshing with the first bevel tooth; An upper bracket and a lower bracket are fixedly mounted on the top of the recovery cylinder, and a discharge roller is installed at one end of the upper bracket and the lower bracket away from the dyeing cylinder, and a water squeezing mechanism is installed between the upper bracket and the lower bracket. A first transmission gear is installed at the end of the two discharge rollers, and the two first transmission gears are meshed with each other. A second longitudinal rotating rod is fixedly installed on the first transmission gear located at the lower side, and a transmission mechanism is commonly provided between the outer wall of the recovery cylinder and the base; The transmission mechanism is used to periodically drive the first longitudinal rotating rod and the second longitudinal rotating rod to rotate respectively. When the first longitudinal rotating rod rotates, the second longitudinal rotating rod does not rotate, so that the discharge roller does not rotate and stops conveying the cloth. The first vertical rotating rods on the upper and lower sides rotate to stir the dye slurry in the dye vat. The cloth in the dye vat is in a dyeing state, and the water squeezing mechanism squeezes the cloth to squeeze out water; when the second longitudinal rotating rod rotates, the first longitudinal rotating rod does not rotate, so that the first vertical rotating rods on the upper and lower sides do not rotate, and the discharge roller rotates to convey the dyed cloth in the dye vat to the water squeezing mechanism, which is in a discharge state, and the water squeezing mechanism does not work.

[0006] The transmission mechanism includes a transmission rotating rod, a transmission assembly and a reciprocating drive assembly. Two transversely arranged damping rotating seats are installed on the outer wall of the recovery cylinder. There are two transmission rotating rods, which are respectively connected to the two damping rotating seats in a damping rotation manner. The two transmission rotating rods are fixedly connected to a second transmission gear, and the two second transmission gears are disengaged and not meshed. The transmission assembly includes a housing, a first motor and an inner gear ring, wherein the inner gear ring is rotatably mounted with the housing and driven to rotate by the first motor, and two second transmission gears are located inside the inner gear ring, and the inner gear ring matches the second transmission gears; The reciprocating drive assembly is used to drive the transmission assembly to move reciprocatingly in the lateral direction.

[0007] The reciprocating drive assembly includes a second motor, a transmission screw and a transmission seat. The second motor is fixedly mounted on the base and the output end is fixedly connected to the transmission screw, the transmission seat is fixedly mounted on the housing, the transmission screw transversely penetrates the transmission seat and is threadedly connected to the transmission seat, the outer wall of the recovery cylinder is also provided with a transverse slide groove, and the housing is provided with a slider slidably connected to the transverse slide groove.

[0008] The lower bracket is U-shaped and has transverse guide rails on both longitudinal sides of the lower bracket. The water squeezing mechanism includes an extrusion airbag installed at the bottom of the upper bracket and a variable platform arranged on the upper side of the lower bracket. The variable platform is composed of a plurality of square platforms, each of which is bonded with airbags on four sides. When the airbags on the four sides are inflated, they form a cylindrical shape together with the square platforms. The transverse guide rails on both sides are slid with a plurality of slides. The two ends of each square platform are rotatably connected with the corresponding slides. The slides close to the dye vat are fixedly connected with the transverse guide rail, and the remaining slides are slidably connected with the transverse guide rail. Two adjacent slides are elastically connected by springs with the same elastic coefficient. Each of the square platforms is provided with an air passage in communication with each of the air bags. Each of the square platforms is connected to an air-filled branch pipe through a rotating joint. Each of the air-filled branch pipes is a hose and is commonly connected to a first air-filled main pipe. The extruded air bag is connected to a second air-filled main pipe. The side of the transverse guide rail away from the dye vat is also slidably connected to a pushing frame, both ends of the pushing frame extend downward, and the lower end of the pushing frame is fixedly connected to a horizontal bar that is slidably connected to the outer wall of the dye vat and the outer wall of the recovery vat, the horizontal bar is located above the slider and a first linkage component is provided between the horizontal bar and the slider.

[0009] The first linkage assembly includes a spur rack and a third transmission gear. There are two spur racks, one of which is processed on the upper side of the slider, and the other is processed on the lower side of the horizontal bar. The third transmission gear is rotatably installed on the outer wall of the recovery cylinder and is meshed with the two spur racks on the upper and lower sides respectively.

[0010] A transverse sleeve is commonly connected between the first inflatable main pipe and the second inflatable main pipe, the two ends of the transverse sleeve are open and not closed, the transverse sleeve is fixed to the upper bracket, a first air inlet hole corresponding to the first inflatable main pipe is opened on the lower side of the transverse sleeve, and a second air inlet hole corresponding to the second inflatable main pipe is opened on the upper side of the transverse sleeve; A slide cylinder is slidably connected inside the transverse sleeve, one end of the slide cylinder close to the dye vat is closed and the other end is connected to an air inlet pipe, a first connecting hole is opened at the lower side of one end of the slide cylinder away from the dye vat and a second connecting hole is opened at the other end; The air inlet pipe and the pushing frame are mounted and fixed via a connecting frame.

[0011] When the slide cylinder slides in a direction away from the dye vat until the first connecting hole is connected with the first air inlet hole, the second connecting hole is staggered with the second air inlet hole, and the extrusion airbag is deflated through the second inflation main pipe, thereby inflating each of the airbags of each of the square strips; When the slide cylinder slides toward the dye vat until the second connecting hole is connected with the second air inlet hole, the first connecting hole is staggered with the first air inlet hole, and the air bags of each square platform are deflated through the first inflation main pipe, thereby inflating the extrusion air bags.

In the discharging state, the water squeezing mechanism does not work, and the cloth is transported to transfer the dyed cloth to the water squeezing mechanism. Step S240: conveying the dyed and squeezed fabric to subsequent drying and winding processes.

[0013] The present invention can periodically enter the immersion dyeing state and the discharging state. In the immersion dyeing state, the discharging roller does not rotate and stops conveying the cloth. The first vertical rotating rods on the upper and lower sides rotate to stir the dye slurry in the dye vat, so that the dye slurry in the dye vat can be kept uniform at all times during the immersion dyeing process of the cloth, thereby ensuring the dyeing effect of the cloth. Since the cloth conveying is stopped, the water squeezing mechanism can squeeze and squeeze water from the cloth. In the discharging state, the first vertical rotating rod does not rotate to stop stirring the dye slurry, and the discharging roller rotates to convey the cloth toward the water squeezing mechanism, so that the cloth after the previous squeezing and squeezing is sent out. Since the cloth is conveyed, the water squeezing mechanism does not work, and the cloth after immersion dyeing can be conveyed toward the water squeezing mechanism, thereby realizing the continuous operation of immersion dyeing and squeezing water from the cloth.

DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Embodiment 1, as Figures 1 to 5 The printing and dyeing equipment of an antibacterial fabric shown in the figure comprises a dyeing vat 100, a recovery vat 110 is integrally fixed to one lateral side of the dyeing vat 100, a base 001 is provided at the bottom of the dyeing vat 100 and the recovery vat 110, first guide rollers 101 are installed on both lateral sides of the inside of the dyeing vat 100, and second guide rollers 102 are installed on both lateral sides of the top of the dyeing vat 100, first vertical rotating rods 103 are rotatably connected to the upper and lower sides of the middle part of the dyeing vat 100, and multiple groups of stirring blades 1031 are installed on the sides of the two first vertical rotating rods 103, and the cloth is pressed by the first vertical rotating rods 103. Figure 1 The method shown in the figure bypasses each first guide roller 101 and each second guide roller 102 respectively. When the cloth is in the dye vat 100, the cloth will pass between the upper and lower first vertical rotating rods 103; A second vertical rotating rod 104 is rotatably connected to one side of the middle longitudinal part of the dye vat 100, and the first vertical rotating rods 103 on the upper and lower sides are connected to the second vertical rotating rod 104 through pulleys and belt transmission. A first bevel gear 1041 is fixedly arranged on the top of the second vertical rotating rod 104. The dye vat 100 is also rotatably connected to a first longitudinal rotating rod 105, and a second bevel gear 1051 meshing with the first bevel gear 1041 is fixedly connected to one end of the first longitudinal rotating rod 105. In this way, when the first longitudinal rotating rod 105 rotates, the second vertical rotating rod 104 can be rotated through the transmission of the second bevel gear 1051 and the first bevel gear 1041. Since the second vertical rotating rod 104 is connected to the first vertical rotating rods 103 on the upper and lower sides through pulleys and belt transmission, the stirring blades 1031 of the first vertical rotating rods 103 on the upper and lower sides can stir the dye slurry to make the dye slurry more evenly dispersed. An upper bracket 111 and a lower bracket 112 are fixedly mounted on the top of the recovery cylinder 110, and a discharge roller 113 is installed at one end of the upper bracket 111 and the lower bracket 112 away from the dye vat 100, and a water squeezing mechanism is installed between the upper bracket 112 and the lower bracket 112. First transmission gears 114 are installed at the ends of the two discharge rollers 113, and the two first transmission gears 114 are meshed with each other. The first transmission gears 114 located on the lower side are fixedly installed with a second longitudinal rotating rod 115. A transmission mechanism is commonly provided between the outer wall of the recovery cylinder 110 and the base 001. In this way, when the second longitudinal rotating rod 115 rotates, the two first transmission gears 114 can be caused to rotate in the opposite direction, thereby causing the upper and lower discharge rollers 113 to rotate in the opposite direction. Figure 1 Taking the perspective as an example, when the lower discharge roller 113 rotates counterclockwise and the upper discharge roller 113 rotates clockwise, the cloth can be conveyed away from the dye vat 100; The transmission mechanism is used to periodically drive the first longitudinal rotating rod 105 and the second longitudinal rotating rod 115 to rotate respectively. When the first longitudinal rotating rod 105 rotates, the second longitudinal rotating rod 115 does not rotate, so that the discharge roller 113 does not rotate and stops conveying the cloth. The first vertical rotating rods 103 on the upper and lower sides rotate to stir the dye slurry in the dye vat 100. The cloth in the dye vat 100 is in a dyeing state, and the water squeezing mechanism squeezes the cloth to squeeze out water; when the second longitudinal rotating rod 115 rotates, the first longitudinal rotating rod 105 does not rotate, so that the first vertical rotating rods 103 on the upper and lower sides do not rotate, and the discharge roller 113 rotates to convey the dyed cloth in the dye vat 100 to the water squeezing mechanism, which is in a discharge state, and the water squeezing mechanism does not work. With this arrangement, the equipment can periodically enter the dyeing state. In the dyeing state and the discharging state, in the dyeing state, the discharging roller 113 does not rotate and stops conveying the cloth, and the first vertical rotating rods 103 on the upper and lower sides rotate to stir the dye slurry in the dyeing vat 100, so that the dye slurry in the dyeing vat 100 can be kept uniform at all times during the dyeing process of the cloth, ensuring the dyeing effect of the cloth, and since the cloth is stopped from being conveyed, the water squeezing mechanism can work to squeeze and squeeze water from the cloth; and in the discharging state, the first vertical rotating rod 103 does not rotate to stop stirring the dye slurry, the water squeezing mechanism does not work, and the discharging roller 113 rotates to convey the cloth toward the water squeezing mechanism, so that the cloth after the previous squeezing and squeezing is sent out, and since the cloth is conveyed, the dyed cloth can be conveyed toward the water squeezing mechanism, so that the continuous operation of dyeing and squeezing water of the cloth can be realized.

[0018] like Figures 1 to 5 As shown, as a further description of the transmission mechanism in this embodiment, the transmission mechanism includes a transmission rotating rod 120, a transmission assembly and a reciprocating drive assembly. Two transversely arranged damping rotating seats 121 are installed on the outer wall of the recovery cylinder 110. There are two transmission rotating rods 120 and they are respectively connected to the two damping rotating seats 121 for damping rotation. The two transmission rotating rods 120 are fixedly connected to the second transmission gears 122. The two second transmission gears 122 are disengaged and not meshed. The transmission rotating rod 120 away from the dye vat 100 is connected to the second longitudinal rotating rod 115 through a pulley and a belt transmission, and the other transmission rotating rod 120 is connected to the first longitudinal rotating rod 105 through a pulley and a belt transmission. The transmission assembly includes a housing 123, a first motor 124 and an inner gear ring 125. The inner gear ring 125 is rotatably mounted with the housing 123 and driven to rotate by the first motor 124. Two second transmission gears 122 are located inside the inner gear ring 125. The inner gear ring 125 matches the second transmission gears 122. The reciprocating drive assembly is used to drive the transmission assembly to reciprocate laterally, and the reciprocating drive assembly includes a second motor 126, a transmission screw 127 and a transmission seat 128; The second motor 126 is fixedly mounted on the base 001 and the output end is fixedly connected to the transmission screw 127. The transmission seat 128 is fixedly mounted on the housing 123. The transmission screw 127 horizontally penetrates the transmission seat 128 and is threadedly connected to the transmission seat 128. A transverse sliding groove 129 is further provided on the outer wall of the recovery cylinder 110 , and a sliding block 1231 slidably connected to the transverse sliding groove 129 is installed on the housing 123 .

[0019] like Figures 1 to 5 In the discharging state shown, the second motor 126 drives the transmission screw 127, so that the transmission seat 128 drives the housing 123 to move toward the dye vat 100, so that the slider 1231 moves to the end of the horizontal slide groove 129 close to the dye vat 100. At this time, the inner gear ring 125 will mesh with the second transmission gear 122 away from the dye vat 100. When the first motor 124 drives the inner gear ring 125 to rotate, the second transmission gear 122 away from the dye vat 100 and the transmission rotating rod 120 can be rotated relative to the damping rotating seat 121. The second longitudinal rotating rod 115 can be rotated through the transmission of the pulley and the belt. Because the two second transmission gears 122 are disengaged and not meshed, the other second transmission gear 122 will not rotate under the connection with the damping rotating seat 121. In the dyeing state, the second motor 126 drives the transmission screw 127, so that the transmission seat 128 drives the housing 123 to move back in the direction away from the dye vat 100, so that the slider 1231 moves to the end of the horizontal slide 129 away from the dye vat 100. At this time, the inner gear ring 125 will mesh with the other second transmission gear 122. When the first motor 124 drives the inner gear ring 125 to rotate, the second transmission gear 122 and the transmission rotating rod 120 can be rotated relative to the damping rotating seat 121. Through the transmission of the pulley and the belt, the first longitudinal rotating rod 105 can be rotated. Because the two second transmission gears 122 are disengaged and not meshed, the second transmission gear 122 away from the dye vat 100 will not rotate under the connection of the damping rotating seat 121. In this way, the housing 123 can be driven reciprocatingly by the second motor 126, and the movement of the inner gear ring 125 can be used to independently drive the first longitudinal rotating rod 105 and the second longitudinal rotating rod 115 to rotate, and under the connection of the damping rotating seat, the transmission rotating rod 120 corresponding to the second transmission gear 122 that is not engaged with the inner gear ring 125 will not rotate under the action of damping; at the same time, in this embodiment, a delayed reversing switch can be provided on both sides of the horizontal slide groove 129, and the start, stop and steering of the second motor 126 can be controlled by the delayed reversing switch, so that when the first motor 126 drives the slider 1231 of the housing 123 to either side of the horizontal slide groove 129, the delayed reversing switch can turn off the first motor 126 and delay for a certain period of time before switching to turn on, so that the equipment can be in the dyeing state and the discharging state for a certain period of time.

[0020] Embodiment 2 is a further improvement made on the basis of Embodiment 1, such as Figures 6 to 11 As shown, the lower bracket 112 is U-shaped and a transverse guide rail 200 is provided on both longitudinal sides of the lower bracket 112. The water squeezing mechanism includes an extrusion airbag 210 installed at the bottom of the upper bracket 111 and a variable platform 220 arranged on the upper side of the lower bracket 112; The variable platform 220 is composed of a plurality of square platforms 221, each of which is bonded with airbags 222 on all four sides. When the airbags 222 on the four sides are inflated, they form a cylindrical shape together with the square platforms 221. The transverse guide rails 200 on both sides are slidably provided with a plurality of slide seats 201. Both ends of each square platform 221 are rotatably connected with the corresponding slide seats 201. The slide seat 201 close to the dye vat 100 is fixedly connected with the transverse guide rail 200, and the remaining slide seats 201 are slidably connected with the transverse guide rail 200. Two adjacent slide seats 201 are elastically connected by springs 202 with the same elastic coefficient. Each square bar platform 221 is provided with an air passage 223 connected to each air bag 222. Each square bar platform 221 is connected to an air filling branch pipe 224 through a rotating joint. Each air filling branch pipe 224 is a hose and is commonly connected to a first air filling main pipe 225. The extrusion air bag 210 is connected to a second air filling main pipe 211. A push frame 203 is also slidably connected to the side of the transverse guide rail 200 away from the dye vat 100. Both ends of the push frame 203 extend downward. The lower end of the push frame 203 is fixedly connected to a horizontal bar 204 that is slidably connected to the outer wall of the dye vat 100 and the outer wall of the recovery vat 110. The horizontal bar 204 is located above the slider 1231 and a first linkage component is provided between the horizontal bar 204 and the slider 1231. The first linkage assembly includes a spur rack 230 and a third transmission gear 231. There are two spur racks 230, one of which is processed on the upper side of the slider 1231, and the other is processed on the lower side of the horizontal bar 204. The third transmission gear 231 is rotatably installed on the outer wall of the recovery cylinder 110 and is meshed with the two spur racks 230 on the upper and lower sides respectively.

[0021] like Figures 6 to 11As shown, in the discharging state, since the slider 1231 moves toward the dye vat 100, the horizontal bar 204 can move away from the dye vat 100 under the transmission of the spur rack 230 and the third transmission gear 231, so that the pushing frame 203 is located on the side of the horizontal guide rail 200 away from the dye vat 100, so that under the elastic action of each spring 202, the distance between each slide seat 201 is at the maximum, and then the distance between each square bar platform 221 is at the maximum, so that the airbag 222 of the square bar platform 221 can be inflated, and by inflating the first inflation main pipe 225 and deflating the second inflation main pipe 221, each square bar platform 221 and the airbags 222 on the four sides are inflated to form a cylindrical shape together, and the squeezing airbag 210 will not generate squeezing force when it is not inflated, so the cloth between the squeezing mechanisms can be directly sent out; In the dyeing state, since the slider 1231 moves back to the direction away from the dye vat 100, the horizontal bar 204 can move toward the dye vat 100 under the transmission of the spur rack 230 and the third transmission gear 231, so that the pushing frame 203 moves toward the dye vat 100 relative to the horizontal guide rail 200, and at the same time, the first inflation pipe 225 is deflated and the second inflation pipe 221 is inflated, and the air bags 222 of the square bar platform 221 are deflated and the squeezing air bag 210 is inflated. Under the push of the pushing frame 203, the elastic force of the spring 202 is overcome to make the slide seats 201 slide close to each other, and then the square bar platforms 221 are pressed against each other to form a platform corresponding to the squeezing air bag 210. Under the air pressure of the squeezing air bag 210, the cloth above the platform composed of a plurality of square platforms 221 is squeezed, and the water removed by squeezing will fall into the recovery tank 110 for recovery.

[0022] like Figures 6 to 11 As shown, as a further improvement of the present embodiment, a transverse sleeve 240 is commonly connected between the first inflatable main pipe 225 and the second inflatable main pipe 211, and the openings at both ends of the transverse sleeve 240 are not closed. The transverse sleeve 240 is fixed to the upper bracket 111, and a first air inlet hole 241 corresponding to the first inflatable main pipe 225 is opened on the lower side of the transverse sleeve 240, and a second air inlet hole 242 corresponding to the second inflatable main pipe 211 is opened on the upper side of the transverse sleeve 240; A slide 243 is slidably connected inside the transverse sleeve 240. One end of the slide 243 close to the dye vat 100 is closed and the other end is connected to an air inlet pipe 244. A first connecting hole 245 is opened at the lower side of one end of the slide 243 away from the dye vat 100 and a second connecting hole 246 is opened at the other end. The air inlet pipe 244 and the push frame 203 are fixedly mounted via a connecting frame 247; When the slide 243 slides away from the dye vat 100 until the first connecting hole 245 is connected with the first air inlet 241, the second connecting hole 246 is staggered with the second air inlet 242, and the airbag 210 is squeezed to deflate through the second inflation main pipe 211, thereby inflating each airbag 222 of each square strip platform 221; When the slide 243 slides toward the dye vat 100 until the second connecting hole 246 is connected to the second air inlet hole 242 , the first connecting hole 245 is staggered from the first air inlet hole 241 , and each airbag 222 of each square bar 221 is deflated through the first inflation main pipe 225 , thereby inflating the extrusion airbag 210 .

[0023] like Figures 6 to 11 As shown, in the discharging state, since the push frame 203 is located on the side of the transverse guide rail 200 away from the dye vat 100, and the air inlet pipe 244 is fixed to the push frame 203, the air inlet pipe 244 will pull the slide 243, so that the first air inlet hole 241 and the first connecting hole 245 are connected, and the second connecting hole 246 is closed by the transverse sleeve 240, and the second air inlet hole 242 is connected to the atmosphere through the other end of the transverse sleeve 240. At this time, the extrusion airbag 210 can be automatically deflated, and when the gas enters through the air inlet pipe 244, it can be filled into the airbag 222 of each square strip table 221 by the first inflation main pipe 225; In the dyeing state, since the push frame 203 moves toward the dye vat 100 relative to the transverse guide rail 200, the air inlet pipe 244 will push the slide 243 to move toward the dye vat 100, and the first connecting hole 245 will be staggered with the first air inlet hole 241, so that the air in each air bag 222 is connected to the atmosphere through each inflation branch pipe 224, the first inflation main pipe 225 and the transverse sleeve 240 and is deflated, and the second connecting hole 246 of the slide will coincide with the second air inlet hole 242, and the first connecting hole 245 will be closed by the transverse sleeve 240. When the gas enters through the air inlet pipe 244, it can be inflated and squeezed into the air bag 210 by the second inflation main pipe 211; In this way, the reciprocating motion of the push frame 203 can realize the alternate inflation and deflation of the squeezing airbag 210 and each airbag 222 .
