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 4A continuous cloth printing and dyeing machine shown in the figure comprises a base 100 and a dye vat 101, a feed guide roller 102 located above the feed side of the dye vat 101 is fixedly mounted on the base 100, and a discharge guide roller 103 located above the discharge side of the dye vat 101 is fixedly mounted on the base 100, U-shaped brackets 110 are movably arranged at both the front and rear ends of the feed side and the discharge side of the dye vat 101, both sides of the U-shaped bracket 110 extend downward along the inner wall and the outer wall of the dye vat 101 to the bottom of the dye vat 101, the tops of the two U-shaped brackets 110 at the front end and the tops of the two U-shaped brackets 110 at the rear end are fixedly connected by a transverse connecting rod 111, and two first tensioning rollers 112 arranged side by side are fixedly connected between the inner lower ends of the two U-shaped brackets 110 at the feed side of the dye vat 101 and between the inner lower ends of the two U-shaped brackets 110 at the discharge side of the dye vat 101; Transverse guide rails 120 are also provided at the front and rear ends of the feeding side and the discharging side of the dye vat 101, and each transverse guide rail 120 is slidably connected with a slide 121. The slide 121 and the transverse guide rail 120 are elastically connected by a first spring 122. A second tensioning roller 123 is commonly provided between the two slides 121 at the front and rear ends. The base 100 is provided with a lifting mechanism, which is transmission-connected to one of the U-shaped brackets 110. The cloth passes around the feed guide roller 102, the second tensioning roller 123 and the first tensioning roller 112 on the feeding side of the dye vat 101 in turn in an S shape, and passes around the first tensioning roller 112, the second tensioning roller 123 and the discharging guide roller 103 on the discharging side of the dye vat 101 in turn in an S shape.

[0018] like Figure 1 and Figure 4 As shown, in this embodiment, the cloth enters from the feeding side of the dye vat 101, and successively bypasses the feeding guide roller 102, the second tensioning roller 123 and the first tensioning roller 112 on the feeding side of the dye vat 101 in an S shape, wherein the cloth overcomes the elastic force of the first spring 122 and stretches the first spring 122 in the process of bypassing the second tensioning roller 123 on the feeding side, so that the slide 121 moves to the end of the transverse guide rail 120 close to the dye vat 101, and successively bypasses the first tensioning roller 112, the second tensioning roller 123 and the discharge guide roller 103 on the discharge side of the dye vat 101 in an S shape, wherein the cloth overcomes the elastic force of the first spring 122 and stretches the first spring 122 in the process of bypassing the second tensioning roller 123 on the discharge side, so that the slide 121 moves to the end of the transverse guide rail 120 close to the dye vat 101, and finally passes through the discharge side of the dye vat 101, and the cloth is dyed by the dye slurry in the dye vat 101; During the dyeing process of the cloth, the corresponding U-shaped brackets 110 can be reciprocated and lifted by the reciprocating lifting of the lifting mechanism, and since the two U-shaped brackets 110 on the feeding side and the discharging side are connected as a whole through the two first tensioning rollers 112 arranged up and down, and the two U-shaped brackets 110 at the front end and the two U-shaped brackets 110 at the rear end are fixed by the transverse tension connecting rod 111, the four U-shaped brackets 110 are connected as a whole. Therefore, when the U-shaped brackets 110 are reciprocated and lifted, the cloth between the first tensioning rollers 112 on both sides can reciprocate up and down in the dye vat 101 to fully contact the dye slurry in the dye vat 101; At the same time, when the cloth between the first tensioning rollers 112 on both sides moves upward, the first springs 122 on both sides elastically rebound and the slides 121 on both sides can be elastically pulled back synchronously, so that the second tensioning rollers 123 on both sides continue to tighten the cloth on both sides to keep the cloth between the first tensioning rollers 112 on both sides tightened. When the cloth between the first tensioning rollers 112 on both sides moves downward, the cloth can overcome the elastic force of the first springs 122 and stretch the first springs 122 to keep the cloth between the first tensioning rollers 112 on both sides tightened. In this way, the cloth between the first tensioning rollers 112 on both sides can be kept tightened during the up and down movement, and the problem of poor cloth dyeing quality due to cloth curling and wrinkling will not occur.

[0019] In this embodiment, a lifting mechanism is provided to enable the cloth between the first tensioning rollers 112 on both sides to move up and down in the dye vat so as to fully contact the dye slurry in the dye vat. In addition, the elastic force can be used to keep the cloth between the first tensioning rollers 112 on both sides taut during the up and down movement of the cloth, and the problem of poor cloth dyeing quality caused by curling and wrinkling of the cloth will not occur.

[0020] As a further description of the lifting mechanism in this embodiment, Figure 3 As shown, the lifting mechanism includes a sliding cavity 113, a motor 114 and a transmission block 115. The sliding cavity 113 is fixedly installed on the base 100 and corresponds to one of the U-shaped brackets 110. The transmission block 115 is slidably connected to the sliding cavity 113 and fixedly connected to the lower end of the outer side of the U-shaped bracket 110. The motor 114 is fixedly installed on the top of the sliding cavity 113. A transmission screw 116 is also rotatably connected inside the sliding cavity 113. The transmission screw 116 penetrates the transmission block 115 and is threadedly connected to the transmission block 115. The output end of the motor 114 is fixedly connected to the transmission screw 116.

[0021] When the motor 114 is started, it can drive the transmission screw 116 in the slide cavity 113 to rotate. Due to the threaded transmission connection between the transmission screw 116 and the transmission block 115, the transmission block 115 can move up and down along the transmission screw 116, so that the fixed U-shaped bracket 110 can move up and down, and then the cloth between the first tensioning rollers 112 on both sides can reciprocate up and down in the dye vat 101 to fully contact the dye slurry in the dye vat 101. At the same time, position switches corresponding to the transmission block 115 are also provided on the upper and lower sides of the slide cavity 113. When the transmission block 115 moves to any position switch, the position switch controls the motor 114 to reverse rotation, so that the rotation direction of the motor 114 can be automatically adjusted to automatically make the transmission block 115 reciprocate up and down.

[0022] As a further improvement of this embodiment, the dye paste in the dye vat is fully stirred to ensure the uniformity of the dye paste. Figure 1 , Figure 2 and Figure 4 As shown, the inner bottom of each U-shaped bracket 110 is commonly connected to a rectangular frame 130 matching the dye vat 101, and a stirring mechanism is commonly provided between the rectangular frame 130 and the inner wall of the dye vat 101; The stirring mechanism includes a plurality of rotating rods 131, a plurality of transmission gears 132 and a plurality of spur racks 133. Each rotating rod 131 extends along the width direction of the rectangular frame 130 and is equidistantly arranged along the length direction of the rectangular frame 130. Both ends of each rotating rod 131 rotate and penetrate the rectangular frame 130. A plurality of stirring blades 134 are processed on the side of each rotating rod 131. Both ends of each rotating rod 131 are fixedly connected to the transmission gear 132. Each spur rack 133 is installed on the inner wall of the dye vat 101 and is respectively meshed with each transmission gear 132.

[0023] When each U-shaped bracket 110 synchronously reciprocates up and down, the rectangular frame 130 fixed at the bottom can reciprocate up and down, and each transmission gear 132 can rotate through the meshing between the transmission gear 132 and the spur rack 133, thereby driving each rotating rod 131 in the rectangular frame 130 to rotate, and then the stirring blades 134 on the side of each rotating rod 131 stir the dye slurry. At the same time, the stirring of the stirring blades 134 follows the up and down movement of the rectangular frame 130. Therefore, the stirring blades 134 will rotate and stir the dye slurry while moving up and down. In this way, the stirring blades 134 can fully stir the dye slurry in the dye vat 101 to improve the uniformity of the dye slurry, and at the same time will not occupy a large amount of internal space of the dye vat 101. At the same time, if Figure 1 and Figure 2As shown, the meshing directions of two adjacent transmission gears 132 and the corresponding two spur racks 133 can be opposite in the manner shown in the figure, so that the stirring blades 134 of two adjacent rotating rods 131 can be turned in the opposite direction, thereby making the stirring flow direction of the dye slurry more variable and improving the stirring effect of the dye slurry.

[0024] As a further optimization of this embodiment, Figure 1 and Figure 4 As shown, a reflux groove 124 communicating with the upper side of the dye vat 101 is further provided between the two transverse guide rails 120 on the feeding side of the dye vat 101 and between the two transverse guide rails 120 on the discharging side of the dye vat 101 .

[0025] When the first tensioning rollers 112 on both sides move upward, the cloth between the first tensioning roller 112 and the second tensioning roller 123 will gradually be located above the reflux groove 124 , and the dripping dye slurry can also flow back into the dye vat 101 through the reflux groove 124 .

[0026] Example 2 is based on Example 1, and further improvements are made to make the dye slurry more evenly distributed on the surface of the cloth and avoid local accumulation leading to color difference. Figures 5 to 9 As shown, a spreading mechanism and a transmission mechanism are also provided between the dye vat 101 and the first tensioning roller 112; Each first tensioning roller 112 is provided with a slideway 200, and a sliding rod 201 is slidably sleeved inside the slideway 200. The spreading mechanism includes an upper spreading frame 210 and a lower spreading frame 211. The two ends of the upper spreading frame 210 are respectively fixedly connected to the sliding rods 201 in the two first tensioning rollers 112 located above, and the two ends of the lower spreading frame 211 are respectively fixedly connected to the sliding rods 201 in the two first tensioning rollers 112 located below, and the upper spreading frame 210 and the lower spreading frame 211 are staggered. The two U-shaped brackets 110 corresponding to the two ends of the first tensioning roller 112 are also provided with arcuate slideways, and the two arcuate slideways are provided with pull wires 202. The upper and lower slide bars 201 are connected to form an annular structure through the pull wires 202 on both sides. The transmission mechanism includes a vertical hydraulic cylinder 220, a longitudinal hydraulic cylinder 221 and a connecting frame 222. The vertical hydraulic cylinder 220 is fixedly mounted on the outer wall of the dye vat 101 and is equipped with a vertical piston rod 2201. The vertical piston rod 2201 extends upward and is fixedly connected to the corresponding transverse connecting rod 111. The longitudinal hydraulic cylinder 221 is fixedly mounted on the outer wall of the dye vat 101 and is equipped with a longitudinal piston rod 2211. The longitudinal piston rod 2211 slides through the dye vat 101 and extends to the dye vat. Inside 101, a positioning seat 2212 is fixedly provided at the end of the longitudinal piston rod 2211, a connecting frame 222 is fixedly connected to the upper stall frame 210 and extends upward, a vertical positioning rod 2221 that slides through the positioning seat 2212 is fixedly provided on the connecting frame 222, a rebound component is also provided between the positioning seat 2212 and the dye vat 101, and the lower end of the vertical hydraulic cylinder 220 is connected to the end of the longitudinal hydraulic cylinder 221 away from the positioning seat 2212 through a hydraulic pipe 2202; like Fig. 9 As shown, the slide bar 201 can slide in the slideway 200. Since the slide bars 201 in the upper and lower slideways 200 are connected by pull wires 202 on both sides to form a ring structure, and the upper paving rack 210 is staggered with the lower paving rack 211, when the upper paving rack 210 moves forward in the dye vat 101, the pull wires 202 on both sides pull the lower paving rack 211 to move backward in the dye vat 101; similarly, when the upper paving rack 210 moves backward, the lower paving rack 211 moves forward.

[0027] When each U-shaped bracket 110 moves up and down synchronously, the transverse connecting rod 111 will also move up and down. When the transverse connecting rod 111 moves upward, the vertical piston rod 2201 moves upward, and the rebound component drives the longitudinal piston rod 2211 to be retracted into the longitudinal hydraulic cylinder 221. The hydraulic oil in the longitudinal hydraulic cylinder 221 enters the vertical hydraulic cylinder 220 through the hydraulic pipe 2202, and the vertical hydraulic cylinder 220 retracts the oil; when the transverse connecting rod 111 moves downward, the vertical piston rod 2201 moves downward, and the hydraulic oil in the vertical hydraulic cylinder 220 enters the longitudinal hydraulic cylinder 221 through the hydraulic pipe 2202, so that the longitudinal piston rod 2211 extends from the longitudinal hydraulic cylinder 221, so that when the U-shaped bracket 110 moves up and down, the longitudinal piston rod 2211 can be extended and retracted forward and backward; When the longitudinal piston rod 2211 is extended and retracted, the positioning seat 2212 at the end of the longitudinal piston rod 2211 cooperates with the vertical positioning rod 2221 of the connecting frame 222, so that the upper berth frame 210 can move forward and backward. At the same time, vertical movement can occur between the vertical positioning rod 2221 and the positioning seat 2212, thereby not hindering the upper berth frame 210, the lower berth frame 211, the first tensioning roller 112 and each U-shaped bracket 110 from moving up and down.

[0028] In this way, the upper spreading frame 210 and the lower spreading frame 211 can be reciprocated forward and backward through the up and down reciprocating motion of the U-shaped bracket 110, so as to spread the upper and lower surfaces of the cloth between the first tensioning rollers 112 on both sides respectively. The spreading can not only make the dye slurry on the surface of the cloth evenly distributed to avoid local accumulation and cause color difference, but also can unfold the cloth in the front and back directions to avoid curling and wrinkling in the front and back directions of the cloth.

[0029] As a structural description of the rebound component in this embodiment, Figure 6 As shown, the rebound assembly includes a longitudinal connecting rod 223 and a second spring 224 , one end of the longitudinal connecting rod 223 is fixedly connected to the positioning seat 2212 , and the other end of the longitudinal connecting rod 223 passes through the dye vat 101 and is fixedly connected to the outer wall of the dye vat 101 via the second spring 224 .

[0030] When the longitudinal hydraulic rod 2211 is extended, the longitudinal connecting rod 223 fixed to the positioning seat 2212 is extended into the dye vat 101, so that the second spring 224 is in an elastic compression state; when the longitudinal hydraulic rod 2211 is retracted, the second spring 224 elastically rebounds, so that the longitudinal connecting rod 223 drives the positioning seat 2212 and the longitudinal hydraulic rod 2211 to return to their original positions.

[0031] As a further explanation of this embodiment, the upper paving frame 210 and the lower paving frame 211 include a plurality of transversely arranged paving rods 212 and at least two paving rods 212 are respectively located at both ends of the slide bar 201, the maximum spacing between two adjacent paving rods 212 is not greater than the fully extended length of the longitudinal piston rod 2211, the size difference between the slide bar 201 and the slideway 200 is equal to the fully extended length of the longitudinal piston rod 2211, and the staggered distance between the upper paving frame 210 and the lower paving frame 211 is equal to the fully extended length of the longitudinal piston rod 2211.

[0032] The purpose of limiting the size relationship in this way is: ① Both ends of the slide bar 201 can fully cover the area of ​​the first tensioning roller 112 through the spreading rod 212; ② During the extension and retraction of the longitudinal piston rod 2211, two adjacent paving rods 212 can fully cover the paving; ③ During the extension and retraction of the longitudinal piston rod 2211, the slide bar 201 can reciprocate in the slideway 200, and at the same time, the upper paving frame 210 and the lower paving frame 211 can fully cover the area between the upper and lower first tensioning rollers 112.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
