[0002] There are many types of strong twist polyester, but they all have common characteristics. One or both sides of the warp and weft combination of polyester fabrics need to be strongly twisted, and the production method adopts white weaving and half-dyed weaving. Grey cloth needs to be refined, alkali-reduced, dyed or printed. In order to make the strong twist polyester cloth feel soft, it is usually necessary to reduce the alkali. After reducing the alkali, grooves are formed on the fiber surface, resulting in poor coloring rate of the grooves formed on the fiber surface during subsequent dyeing. The dye is not easy to dye in the gaps in the grooves, which ultimately leads to the overall low dyeing rate of the strong twist polyester cloth.

[0003] The patent document with patent number CN202021275749.4 discloses a napping machine for printing and dyeing that is convenient for cleaning cloth scraps, the cleaning mechanism comprising a mounting plate, the mounting plate being mounted at the discharge port of the napping machine, a roller being rotatably mounted on the mounting plate, a sticker being glued on the roller, a scraper being hinged on the mounting plate, one side of the scraper being against the outer wall of the roller, and one side of the scraper being hinged with a telescopic structure, the telescopic structure comprising a first sliding rod, a sliding tube, a spring and a second sliding rod, one end of the first sliding rod being hinged on the mounting plate, the other end of the first sliding rod being inserted into the top end of the sliding tube, one end of the second sliding rod being hinged on the scraper, the other end of the second sliding rod being inserted into the bottom end of the sliding tube, the spring being arranged inside the sliding tube, and a collecting trough being installed on one side of the mounting plate.

[0043] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0044] Embodiment 1

[0045] like Figure 1-17 As shown, a strong twist polyester fabric dyeing device comprises a traction mechanism 2 arranged on a conveying frame 1, a processing mechanism 3 arranged on the conveying frame 1 and used for dyeing the fabric before dyeing, and a dyeing mechanism 4 arranged on the conveying frame 1;

[0046] The processing mechanism 3 includes a perforating component 31, a hair pulling component 32 and a hair removal component 33 which are arranged on the conveying frame 1 from left to right in sequence;

[0047] The dyeing mechanism 4 includes a pre-dyeing component 41 disposed on the conveying frame 1 and used for pre-dyeing the raised fluff of the fabric, and a dyeing component 42 disposed on the conveying frame 1 and used for dyeing the fabric.

[0048] In this embodiment, by cooperating with the processing mechanism 3 and the dyeing mechanism 4, on the one hand, the fabric can be automatically pulled before dyeing and the hair on the fabric can be cleaned, which is convenient for the overall dyeing of the fabric, avoids the appearance of white spots on the fabric, improves the dyeing effect of the fabric, and increases the aesthetics of the fabric; on the other hand, the fluff on the fabric can be pre-dyed to ensure that the fluff is dyed evenly, and in the process of dyeing the fabric, the fabric can be automatically pulled repeatedly to ensure that the fabric is dyed transparently, thereby accelerating the dyeing speed of the fabric, with high automation and good linkage, thereby improving the dyeing efficiency of the fabric.

[0049] In detail, the clamping assembly 22 of the traction mechanism 2 pulls the fabric through the perforating assembly 31, the napping assembly 32, the delinting assembly 33, the pre-dyeing assembly 41 and the dyeing assembly 42 in sequence. When the fabric passes through the perforating assembly 31 and the napping assembly 32, the clamping assembly 22 pulls the fabric tightly to both sides to facilitate the punching and napping of the fabric, so that the through holes and the fluff are alternately distributed in rows on the fabric. Then, when the fabric passes through the delinting assembly 33, the clamping assembly 22 rotates and bends the fabric to open the fluff pulled up on the fabric, making it convenient to clean the fluff at the bottom of the fluff, so that the delinting assembly 33 cleans the through holes and the fluff on the fabric in sequence. Then, when the fabric passes through the pre-dyeing assembly 41, The clamping component 22 rotates again and bends the fabric to open the fluff pulled up on the fabric, making it convenient to spray the dye to the bottom of the fluff. The squeezing roller 419 then squeezes out the dye at the bottom of the fluff on the fabric to make the bottom of the fluff evenly dyed. Then, while the fabric passes through the dyeing component 42, the clamping component 22 pulls the fabric into the dye, and the pulling member 421, driven by the transmission member 422, causes the ejector pin 4213 to be inserted into the through hole of the fabric accordingly. Moreover, while the ejector pin 4213 and the fabric are being conveyed forward synchronously, the ejector pin 4213 repeatedly moves to both sides to repeatedly pull the fabric, so that the fabric is dyed transparently and the dyeing time of the fabric is shortened. After the fabric is dyed, it is output to the next workstation under the traction of the clamping component 22.

[0050] Further, if Figure 1-5 As shown, the traction mechanism 2 includes two groups of chains 21 symmetrically arranged on the conveying frame 1 and running synchronously, a plurality of groups of clamping components 22 arranged on the chains 21 and used to clamp the edges of the fabric, and an opening component 23 arranged on the conveying frame 1 and used to start the clamping components 22;

[0051] It should be noted that the fabric enters the traction mechanism 2 from the previous process or the existing winding roller, and the chain 21 runs under the drive of the existing power source.

[0052] The clamping assembly 22 includes a lifting rod 221 penetrating the chain 21, a lifting block 222 arranged at the lower end of the lifting rod 221, a translation rod 223 penetrating and slidably arranged on the lifting block 222, a vertical plate arranged at one end of the translation rod 223, a bottom plate 224 arranged on the vertical plate, a clamping plate 225 arranged on the vertical plate for lifting and lowering through a slide groove, a first elastic member arranged between the clamping plate 225 and the vertical plate and used to drive the clamping plate 225, a gear 226 arranged at the other end of the translation rod 223, a second elastic member arranged between the gear 226 and the lifting block 222, a contact head 227 arranged at the upper end of the lifting rod 221, and a third elastic member arranged between the contact head 227 and the chain 21, and anti-slip points are arranged on the surface of the clamping plate 225 and the surface of the bottom plate 224 to clamp the fabric tightly;

[0053] It should be noted that a damper is provided at the connection between the translation rod and the vertical plate;

[0054] The opening assembly 23 includes two groups of first limiting rails 231 symmetrically arranged on the conveying frame 1 through brackets and used to drive the gear 226 to move the clamp plate 225 to both sides, a second limiting rail 232 arranged on the first limiting rail 231 through a bracket and used to drive the clamp plate 225 to rise, and an extension rod 233 arranged on the clamp plate 225 and slidingly matched with the second limiting rail 232.

[0055] In this embodiment, the clamping assembly 22 and the opening assembly 23 cooperate with each other so that the clamping assembly 22 can automatically clamp the edge of the fabric so as to pull the fabric forward and transport it to complete the processing work in sequence.

[0056] In detail, the chain 21 is driven by the existing power source to operate, so that when the clamping component 22 passes the position of the opening component 23, the first limiting track 231 drives the gear 226 to move the translation rod 223 to both sides, so that the translation rod 223 moves the clamping plate 225 to both sides of the fabric, and then, the second limiting track 232 drives the extension rod 233 to move the clamping plate 225 upward, and the clamping plate 225 moves inwardly to reset under the drive of the second elastic member, and then, the clamping plate 225 is driven by the first elastic member to descend and reset, so that the clamping plate 225 and the bottom plate 224 cooperate to clamp the edge of the fabric to pull the fabric forward.

[0057] Further, if Figure 6-7As shown, the perforating assembly 31 includes a transverse plate 311 arranged on the conveying frame 1 through a bracket, two groups of first transmission rollers 313 rotatably arranged on the transverse plate 311 and having a plurality of groups of punching needles 312 on the peripheral side thereof, and a third limiting track 314 arranged on the conveying frame 1 through a bracket and used for driving the gear 226 to move the clamping plate 225 to both sides to tighten the fabric, and the first transmission roller 313 runs synchronously with the chain 21.

[0058] It should be noted that the first transmission roller 313 is driven by an existing power source.

[0059] In this embodiment, by cooperating with the punching component 31 and the clamping component 22, on the one hand, the fabric can be pre-punched so that the ejector pin 4213 of the pulling member 421 can pass through the fabric, thereby ensuring that the pulling member 421 can automatically pull the fabric; on the other hand, during the operation of the punching component 31, the clamping component 22 can pull the fabric tight to both sides to avoid wrinkles in the fabric, thereby ensuring smooth punching of the fabric, with high automation and good linkage, thereby improving the stability of fabric punching.

[0060] In detail, when the clamping assembly 22 pulls the fabric to the position of the punching assembly 31, the third limiting track 314 drives the gear 226 to move the clamping plate 225 to both sides to tighten the fabric. At the same time, the fabric passes through the gap between the two first transmission rollers 313, so that the punching needles 312 on the two first transmission rollers 313 cooperate to punch holes in the fabric.

[0061] Further, if Figure 6-8 As shown, the napping assembly 32 includes two groups of second transmission rollers 321 rotatably arranged on the horizontal plate 311 and several groups of napping heads 322 arranged on the second transmission rollers 321. The second transmission rollers 321 and the first transmission rollers 313 operate synchronously through the transmission mode of pulleys and belts.

[0062] It should be noted that, by setting the distribution of the punching needles 312 on the first transmission roller 313 and the distribution of the napping heads 322 on the second transmission roller 321, it is possible to achieve alternating distribution of through holes and nap in rows on the fabric.

[0063] In this embodiment, by cooperating with the napping component 32 and the clamping component 22, the surface of the fabric can be napped before the fabric is dyed.

[0064] In detail, when the clamping assembly 22 pulls the fabric to the position of the napping assembly 32, the clamping plate 225 still pulls the fabric tightly under the drive of the third limiting track 314, and the fabric passes through the gap between the two second transmission rollers 321, so that the napping heads 322 on the two second transmission rollers 321 cooperate to perform napping treatment on the fabric.

[0065] Further, if Figure 6-8 As shown, the delinting assembly 33 includes two sets of third transmission rollers 331 staggeredly arranged on the transverse plate 311 and respectively used to clean the upper surface and the lower surface of the fabric, a plurality of sets of brushes 332 arranged on the third transmission rollers 331, a plurality of sets of suction holes 333 arranged on the third transmission rollers 331 and located on one side of the brushes 332, two sets of first racks 334 arranged on the conveying frame 1 and used to drive the gear 226 to rotate with the clamping plate 225 to open the fluff pulled up on the upper surface of the fabric, and two sets of first racks 334 arranged on the conveying frame 1. The second rack 335 on the conveyor frame 1 is used to drive the gear 226 to rotate with the clamp 225 to open the fluff pulled up on the lower surface of the fabric. The first rack 334 is arranged below the gear 226 and is located on one side of the end of the third transmission roller 331. The second rack 335 is arranged above the gear 226 and is located on one side of the end of another third transmission roller 331. The third transmission roller 331 and the second transmission roller 321 operate synchronously and differentially through the transmission method of pulleys and belts.

[0066] It is worth mentioning that the rotation speed of the third transmission roller 331 of the lint removal assembly 33 is greater than the forward speed of the fabric, so that the brush 332 of the third transmission roller 331 can brush off the fluff on the fabric.

[0067] It should be noted that the first rack 334 drives the gear 226 to rotate with the clamp 225 to open the fluff on the upper surface of the fabric, so as to clean the hair debris at the bottom of the fluff. At the same time, the second elastic member of the clamping assembly 22 is deformed due to self-rotation. Then, after cleaning the hair debris at the bottom of the fluff, the second elastic member rotates in the opposite direction to reset, so that the gear 226 is driven by the second elastic member to reset with the clamp 225, so that the fabric is restored to a flat state.

[0068] It should also be noted that the third transmission roller 331 is a hollow structure, the suction hole 333 penetrates into the third transmission roller 331, and the end of the third transmission roller 331 is connected to the existing vacuum generator through an air pipe.

[0069] In this embodiment, the lint removal component 33 and the clamping component 22 cooperate to automatically clean the lint in the holes and fluff on the fabric, preventing the lint from being immersed in the dye solution along with the fabric, affecting the dyeing of the fabric and causing white spots.

[0070] In detail, when the clamping assembly 22 pulls the fabric to the position of the lint removal assembly 33, the first rack 334 drives the gear 226 to rotate with the clamp 225, so that the fabric is bent to open the fluff on the upper surface of the fabric. When the fabric passes through the third transmission roller 331, the brush 332 on the third transmission roller 331 brushes up the fluff again. At the same time, the suction hole 333 on the third transmission roller 331 cleans the lint at the bottom of the fluff. Then, the second rack 335 drives the gear 226 to rotate with the clamp 225, so that the fabric is bent to open the fluff on the lower surface of the fabric. The suction hole 333 on the third transmission roller 331 cleans the lint at the bottom of the fluff, thereby cleaning the lint on the upper and lower surfaces of the fabric in turn.

[0071] Further, if Figure 10-13 As shown, the pre-dyeing component 41 includes a dye box 411 arranged on the conveying frame 1 and filled with dye liquid, two groups of fourth limiting rails 412 arranged on the conveying frame 1 and used to drive the lifting rod 221 to bring the fabric down and enter the dye box 411, a first transfer box 413 arranged between the two fourth limiting rails 412 and connected to the inside of the dye box 411 through a connecting pipe, a first mounting bar 414 arranged on the first transfer box 413 through a hanging rod, a plurality of groups of first nozzles obliquely arranged on the first mounting bar 414 and used to spray dye liquid onto the fluff on the upper surface of the fabric, and two groups of first nozzles arranged on the inner wall of the dye box 411 and used to drive the gear 226 to rotate with the clamping plate 225 to open the fluff pulled up on the upper surface of the fabric. a third rack 415, a second transfer box 416 arranged on the inner wall of the dye box 411 and connected to the inside of the dye box 411 through a connecting pipe, a second mounting bar 417 arranged on the second transfer box 416 through a support rod, a plurality of groups of second nozzles obliquely arranged on the second mounting bar 417 and used for spraying dye liquid onto the fluff on the lower surface of the fabric, two groups of fourth racks 418 arranged on the inner wall of the dye box 411 and used for driving the gear 226 to rotate with the clamp 225 to open the fluff pulled up on the lower surface of the fabric, and two groups of squeezing rollers 419 arranged on the inner wall of the dye box 411 and used for the fluff to evenly absorb the dye liquid, and the input end of the first transfer box 413 and the input end of the second transfer box 416 are both provided with filters.

[0072] It should be noted that both the first transfer box 413 and the second transfer box 416 are provided with existing pump bodies for extracting dye liquid in the dye box 411, and both the first nozzle and the second nozzle are existing high-pressure nozzles with solenoid valves.

[0073] In this embodiment, by cooperating with the pre-dyeing component 41 and the clamping component 22, on the one hand, the fluff on the fabric can be automatically opened before the fluff on the fabric is pre-dyed, ensuring that the dye liquid can be sprayed to the bottom of the fluff, so that the fluff is dyed evenly, thereby improving the pre-dyeing effect of the fluff; on the other hand, the dye liquid required for pre-dyeing is extracted from the dye box 411 and sprayed onto the fluff after filtering, thereby purifying the dye liquid in the dye box 411, improving the cleanliness of the dye liquid, and facilitating the dyeing work of the fabric.

[0074] In detail, after the clamping assembly 22 pulls the fabric to the position of the dye box 411, the fourth limiting rail 412 drives the lifting rod 221 to bring the fabric down and enter the dye box 411, and then, the third rack 415 drives the gear 226 to rotate with the clamp 225 to open the fluff on the upper surface of the fabric, and the first nozzle on the first mounting strip 414 sprays dye on the opened fluff, and then, the fourth rack 418 drives the gear 226 to rotate with the clamp 225 to open the fluff on the lower surface of the fabric, and the second nozzle on the second mounting strip 417 sprays dye on the opened fluff, thereby pre-dyeing the fluff on the upper and lower surfaces of the fabric, and then, the squeezing roller 419 squeezes out excess dye at the bottom of the fluff, so that the dye at the bottom of the fluff flows around, so that the bottom of the fluff is evenly dyed, and finally, the pre-dyed fabric enters the dye liquid in the dye box 411 for immersion dyeing.

[0075] Further, if Figure 11-17 As shown, the dyeing assembly 42 includes a pulling member 421 disposed in the dye box 411 and used to pull the fabric in the dye solution, and a transmission member 422 disposed on the inner wall of the dye box 411 and used to drive the pulling member 421 to work;

[0076] The pulling member 421 includes a conveyor belt 4211 disposed in the dye box 411 and running synchronously with the chain 21, a plurality of groups of sliding holes opened on the conveyor belt 4211, a plurality of groups of sliders 4212 slidably disposed in the sliding holes, a fourth elastic member disposed between two adjacent sliders 4212, an ejector pin 4213 penetrating and lifted and disposed on the slider 4212, and a fifth elastic member disposed between the lower end of the ejector pin 4213 and the slider 4212;

[0077] The transmission member 422 includes a fifth limiting rail 4221 arranged on the inner wall of the dye box 411 and used to drive the ejector pin 4213 to rise, a plurality of groups of slideways 4222 opened on the fifth limiting rail 4221 and corresponding to the ejector pin 4213 respectively, and a wave bar 4223 arranged in the slideway 4222 and used to drive the ejector pin 4213 to move repeatedly to both sides.

[0078] It should be noted that the conveyor belt 4211 of the pulling member 421 is driven by an existing power source, so that the rotation speed of the conveyor belt 4211 is consistent with the forward speed of the fabric.

[0079] In this embodiment, by cooperating with the pulling member 421 and the transmission member 422, the fabric can be repeatedly pulled to both sides during the fabric dyeing process, so that the fabric can be dyed thoroughly, shortening the fabric dyeing time and improving production efficiency.

[0080] In detail, after the clamping assembly 22 pulls the fabric to move to the horizontal part of the fourth limiting track 412, the fabric is immersed in the dye liquid in the dye box 411, and the ejector pin 4213 of the pulling member 421 is driven to rise by the fifth limiting track 4221, so that the ejector pin 4213 is correspondingly inserted into the through hole of the fabric, and then, the ejector pin 4213 is driven to move to both sides by the protrusion of the wave bar 4223, so that the ejector pin 4213 pulls the fabric to both sides, and then, the ejector pin 4213 is driven to reset by the fourth elastic member, so that the ejector pin 4213 repeatedly pulls the fabric to both sides during the process of passing through the wave bar 4223.

[0081] Embodiment 2

[0082] like Figure 10-11 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0083] Further, if Figure 10-11 As shown, the dyeing assembly 42 also includes a drain roller 43 disposed in the dye box 411 and used to remove excess dye on the fabric.

[0084] It is worth mentioning that, by setting up the drain roller 43, when the fabric is output from the dye box 411 after being dyed, the drain roller 43 can squeeze out the excess dye on the fabric, which speeds up the drying speed of the fabric after dyeing and can also recover the excess dye to the dye box 411, saving the use of dye.

[0085] Working process:

[0086] The clamping assembly 22 of the traction mechanism 2 pulls the fabric through the perforating assembly 31, the napping assembly 32, the delinting assembly 33, the pre-dyeing assembly 41 and the dyeing assembly 42 in sequence. When the fabric passes through the perforating assembly 31 and the napping assembly 32, the clamping assembly 22 pulls the fabric tightly to both sides to facilitate the punching and napping of the fabric, so that through holes and fluff are alternately distributed in rows on the fabric. Then, when the fabric passes through the delinting assembly 33, the clamping assembly 22 rotates and bends the fabric to open the fluff pulled up on the fabric, which is convenient for cleaning the fluff at the bottom of the fluff, so that the delinting assembly 33 cleans the through holes and fluff on the fabric in sequence. Then, when the fabric passes through the pre-dyeing assembly 41, the clamping assembly 22 rotates and bends the fabric again to open the fabric. The fluff pulled up on the material makes it convenient to spray the dye to the bottom of the fluff, and the squeezing roller 419 squeezes out the dye at the bottom of the fluff on the fabric, so that the bottom of the fluff is dyed evenly. Then, when the fabric passes through the dyeing component 42, the clamping component 22 pulls the fabric into the dye, and the pulling member 421 is driven by the transmission member 422 to make the ejector pin 4213 insert into the through hole of the fabric accordingly. Moreover, in the process of the ejector pin 4213 and the fabric being conveyed forward synchronously, the ejector pin 4213 repeatedly moves to both sides to repeatedly pull the fabric, so that the fabric is dyed transparently and the dyeing time of the fabric is shortened. Finally, after the fabric is dyed, when it is output from the dye box 411 under the traction of the clamping component 22, the drain roller 43 squeezes out the excess dye on the fabric, and the clamping component 22 pulls the fabric to the next station.
