Description

Technical Field

[0001] The present invention relates to the technical field of textile printing and dyeing, and particularly to a same-bath textile printing and dyeing device and a printing and dyeing method thereof. Background Art

[0002] Same-bath dyeing means adding different types of dyes or finishing agents into a solvent, and performing dyeing and finishing on the fabric by controlling the dyeing and finishing process conditions, so as to shorten the production line and save costs. During the dyeing process, it is necessary to consider the problem of the uniformity of dye mixing, and also need to consider the problem of the penetrability between the dye and the textile fabric to ensure that the dye can be better printed on the textile fabric. Moreover, during printing and dyeing, the printed textile fabric also needs to be squeezed to extrude the excess dye on the fabric, and generally a two-dyeing and two-squeezing method is adopted during printing and dyeing, so that the color can be firmly printed on the textile fabric.

[0003] Chinese Patent Application Publication No.: CN202110208430.2, Patent Name: Reactive Dye Same-bath Dyeing Device. The reactive dye same-bath dyeing device of the present invention can shorten the dyeing impregnation process, swing the fabric to be dyed periodically, and can better mix the dye liquor while achieving a better impregnation effect. That is, this application can make the dye be printed on the textile fabric, and at the same time can stir the dye to make the dye mix more evenly, but it cannot adopt the two-dyeing and two-squeezing method. Moreover, for traditional two-dyeing and two-squeezing, the pulling force required when pulling the fabric is large, that is, the resistance received during this process is large, resulting in the fabric being easily pulled and deformed, which is not conducive to the processing of the fabric, and the time spent on two-dyeing and two-squeezing is relatively long.

[0004] Therefore, it is necessary to design a same-bath textile printing and dyeing device and a printing and dyeing method, which can make the dye be better printed on the textile fabric, can stir the dye at the same time, can adopt the two-dyeing and two-squeezing method, can reduce the resistance received when pulling the fabric, and can shorten the time spent on two-dyeing and two-squeezing. Summary of the Invention

[0005] Aiming at the above existing technical deficiencies, the purpose of the present invention is to provide a same-bath textile printing and dyeing device and a printing and dyeing method, which can make the dye be better printed on the textile fabric, can stir the dye at the same time, can adopt the two-dyeing and two-squeezing method, can reduce the resistance received when pulling the fabric, and can shorten the time spent on two-dyeing and two-squeezing.

[0006] To achieve the above object, the present invention adopts the following technical solutions: The present invention provides a co-bath textile printing and dyeing device and a printing and dyeing method, including a box body, a clamping mechanism, a linear pushing mechanism, a jacking mechanism, two water flow pushing plates, four squeezing rollers and a plurality of guiding rollers. The plurality of guiding rollers are rotatably installed on the box body, and the textile fabric is wound and tightened on the outer edges of the plurality of guiding rollers. Two bottom horizontal sections and two top horizontal sections are formed between the textile fabric and the guiding rollers. The two water flow pushing plates are respectively located below the two bottom horizontal sections. The jacking mechanism is used to push the water flow pushing plates upward. Every two squeezing rollers are respectively located on the upper and lower sides of a top horizontal section. The four squeezing rollers are fixedly installed on the clamping mechanism. The clamping mechanism is used to drive the four squeezing rollers to clamp the two top horizontal sections respectively. The linear pushing mechanism is used to push the clamping mechanism to move linearly along the top horizontal section.

[0007] Preferably, the linear pushing mechanism includes a first contact block, two hinge rods and two vertical sliding rods. One ends of the two hinge rods are hinged to the clamping mechanism.

The two water flow pushing plates are fixedly installed on the top of the vertical pushing seat. The trapezoidal block is fixedly installed at the horizontal pushing end of the horizontal pushing mechanism. The horizontal pushing mechanism is fixedly installed on the box body. The horizontal pushing mechanism is used to jack up the vertical pushing seat and the first contact block by pushing the trapezoidal block upward. When the inclined surface of the trapezoidal block contacts the first contact block, the bottom of the vertical pushing seat contacts the top flat end of the trapezoidal block, and the water flow pushing plates and the guiding rollers clamp the bottom horizontal section.

The first mounting frame is slidably installed on the box horizontally. The hinge seat is fixedly connected to the first mounting frame. The four stop bars are fixedly installed on the inner side of the box through the mounting seat. The ends of the two extrusion rollers are located inside the stop bars. The upper and lower two elastic lifting mechanisms are used to pull the ends of the two extrusion rollers to fit with the two stop bars respectively. The elastic lifting mechanism is fixedly installed on the first mounting frame. A groove is formed at the end of the stop bar for the extrusion roller to separate from the top horizontal section. When the extrusion roller contacts the bottom of the groove, the inner sides of the two extrusion rollers are separated from the top horizontal section. When the extrusion roller contacts the inner end face of the stop bar, the two extrusion rollers squeeze the top horizontal section.

[0009] Preferably, each elastic lifting mechanism includes a rotating ring, a sliding column, a pushing spring and a locking nut. The rotating ring is fixedly installed at the end of the sliding column. The end of the extrusion roller is inserted into the rotating ring. The sliding column is slidably connected to the first mounting frame. The locking nut is meshed and installed at the top of the sliding column. The pushing spring is used to provide an elastic force for the locking nut away from the extrusion roller.

[0010] Preferably, a slide rail is fixedly arranged on the inner edge of the box. A slider is fixedly arranged on the first mounting frame. The slider is slidably connected to the slide rail.

[0011] Preferably, an extension column is arranged on the hinge seat. The extension column passes through the box and is fixedly connected to the first mounting frame. A kidney-shaped hole for the extension column to pass through is formed on the box.

[0012] Preferably, the vertical pushing seat includes a second mounting frame, a lower sliding column, a second contact block, four upper sliding columns and four guide seats.

[0013] Preferably, the horizontal pushing mechanism includes a pushing cylinder, a guide frame and two guide columns. The guide frame is fixedly installed on the box. The guide columns are slidably installed on the guide frame horizontally. The trapezoidal block is fixedly installed at the ends of the two guide columns. The pushing cylinder is fixedly installed on the guide frame. The output end of the pushing cylinder is fixedly connected to the trapezoidal block.

[0014] Preferably, an elastic telescopic rod one and an elastic telescopic rod two are fixedly arranged at the bottom of the box body. The bottom of the elastic telescopic rod one abuts against the top of the contact block two, and the bottom of the elastic telescopic rod two contacts the top of the contact block one.

[0015] A printing and dyeing method for a same-bath textile printing and dyeing device, characterized by comprising the following steps:

[0016] Step one: The dye is pushed towards the bottom horizontal section, and the water flow pushing plate presses the bottom horizontal section.

[0017] The horizontal pushing mechanism pushes horizontally. The trapezoidal block moves the vertical pushing seat upward, causing the water flow pushing plate to move upward. The water flow pushing plate pushes the dye towards the bottom horizontal section, enabling the dye to better penetrate the bottom horizontal section. Finally, the water flow pushing plate presses the bottom horizontal section against the guiding rod.

[0018] Step two: The clamping mechanism drives the extrusion roller to reciprocate to extrude the dye on the top horizontal section.

[0019] As the horizontal pushing mechanism continues to move horizontally, the horizontal pushing mechanism pushes the contact block one upward, causing the articulated rod to drive the clamping mechanism to move to the left. The two extrusion rollers slide inward along the groove to extrude the top horizontal section. As the clamping mechanism continues to move, the dye on the top horizontal section is extruded. Subsequently, the horizontal pushing mechanism performs a reset movement. Due to the self-weight of the linear pushing mechanism and the elastic force exerted by the elastic telescopic rod two, the articulated rod pulls the clamping mechanism to reset to the right, and the two extrusion rollers extrude the top horizontal section again, causing the dye that was not extruded on the top horizontal section to be extruded again.

[0020] Step three: The water flow pushing plate releases the pressing on the bottom horizontal section.

[0021] The horizontal pushing mechanism pulls the trapezoidal block to reset. When the trapezoidal block separates from the vertical pushing seat, due to the gravity of the vertical pushing seat and the downward elastic force of the elastic telescopic rod two, the water flow pushing plate is pulled downward, that is, the pressing on the bottom horizontal section is released, and a downward suction force is generated, enabling the dye above the bottom horizontal section to better penetrate the bottom horizontal section.

[0022] Step four: Pull the textile fabric.

[0023] When the extrusion roller returns to contact with the groove, the two extrusion rollers separate from the top horizontal section, and the water flow pushing plate releases the pressing on the bottom horizontal section. At this time, the driving mechanism outside the box body pulls the textile fabric to move along the guiding rod.

[0024] The beneficial effects of the present invention are as follows: The co-bath textile printing and dyeing equipment and the printing and dyeing method can make the dye penetrate the bottom horizontal section better by the up-and-down movement of the water flow pushing plate, resulting in a better printing and dyeing effect on the textile fabric, and can also agitate the dye.

[0025] When the squeezing roller is in the initial position, it can release the clamping of the textile fabric, so that the textile fabric can be pulled more smoothly by the pulling device along the guiding roller, reducing the resistance suffered by the guiding roller in this process.

[0026] When the clamping mechanism drives the squeezing roller to squeeze the top horizontal section, the water flow pushing plate can automatically press the bottom horizontal section tightly, preventing the textile fabric from being pulled and offset by the squeezing roller and ensuring the flatness of the fabric. And through one push of the horizontal pushing mechanism, the water flow pushing plate can pre-press the bottom horizontal section, and at the same time, the two squeezing rollers can reciprocally extrude the dye on the top horizontal section. The whole process is relatively smooth, and before and after the two squeezing rollers squeeze the top horizontal section, the clamping mechanism will not pause, saving the working time of the equipment.

[0027] Moreover, according to the water absorption of the dye, the working speed of the horizontal pushing mechanism can be directly controlled, that is, the working speed of the whole equipment can be changed. For textile fabrics with strong water absorption, the working speed of the horizontal pushing mechanism is slowed down, while for textile fabrics with weak water absorption, the working speed of the horizontal pushing mechanism can be increased.

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment: The present invention provides a same-bath textile printing and dyeing device and a printing and dyeing method, as Figure 1 and Figure 2As shown, it includes a box body 1, a clamping mechanism 2, a linear pushing mechanism 4, a jacking mechanism 5, two water flow pushing plates 6, four squeezing rollers 3 and a plurality of guiding rollers 7. The plurality of guiding rollers 7 are rotatably installed on the box body 1. The textile fabric 8 enters along the feed port of the box body 1, and the textile fabric 8 is wound and tightened on the outer edges of the plurality of guiding rollers 7. Finally, the textile fabric 8 is discharged along the discharge port of the box body 1. Two bottom horizontal sections 8a and two top horizontal sections 8b are formed between the textile fabric 8 and the guiding rollers 7. The two water flow pushing plates 6 are respectively located below the two bottom horizontal sections 8a. The jacking mechanism 5 is used to push the water flow pushing plates 6 upward, so that the two water flow pushing plates 6 can push the dye upward to impact the bottom horizontal section 8a. And when the jacking mechanism 5 drives the water flow pushing plates 6 to move downward, it can suck the dye downward, so that the dye can impact the bottom horizontal section 8a, making the dye better printed on the textile fabric 8. And when the water flow pushing plates 6 move, they can stir the dye in the box body 1, making the dyes in the same bath better mixed. Every two squeezing rollers 3 are respectively located on the upper and lower sides of a top horizontal section 8b. The four squeezing rollers 3 are fixedly installed on the clamping mechanism 2. The clamping mechanism 2 is used to drive the four squeezing rollers 3 to clamp the two top horizontal sections 8b respectively. The linear pushing mechanism 4 is used to push the clamping mechanism 2 to move linearly along the top horizontal section 8b, so that the squeezing rollers 3 squeeze out the dye on the top horizontal section 8b, and the squeezed dye will fall back into the box body 1. Wherein the liquid level of the dye in the box body 1 is located below the squeezing rollers 3, and it is necessary to ensure that when the water flow pushing plates 6 move upward or downward, the dye will not come into contact with the top horizontal section 8b. Through the above method, two dyeings and two squeezings of the textile fabric 8 can be realized, ensuring that the color dyed on the bottom horizontal section 8a can be more consolidated.

[0041] However, in order to have a higher liquid level so that the fabric can be in contact with the fabric for a longer time. And in order that when the squeezing rollers 3 are pushed by the linear pushing mechanism 4, the squeezing rollers 3 will horizontally pull the top horizontal section 8b along the guiding rollers 7. For this reason, as Figure 2 and Figure 3As shown, the linear displacement mechanism 4 includes a first contact block 4c, two articulated rods 4a, and two vertical sliding rods 4b. One end of each of the two articulated rods 4a is articulated to the clamping mechanism 2, and the other ends of the two vertical sliding rods 4b are respectively articulated to the tops of the two articulated rods 4a. The vertical sliding rods 4b are slidably mounted on the box body 1 vertically. The first contact block 4c is fixedly mounted at the bottoms of the two vertical sliding rods 4b. The jacking mechanism 5 includes a horizontal pushing mechanism 5a, a vertical pushing seat 5b, and a trapezoidal block 5c. The vertical pushing seat 5b is slidably mounted on the box body 1 vertically. Both of the two water flow pushing plates 6 are fixedly mounted at the top of the vertical pushing seat 5b. The trapezoidal block 5c is fixedly mounted at the horizontal pushing end of the horizontal pushing mechanism 5a. The horizontal pushing mechanism 5a is fixedly mounted on the box body 1. The horizontal pushing mechanism 5a is used to jack up the vertical pushing seat 5b and the first contact block 4c by pushing the trapezoidal block 5c upward. When the inclined surface of the trapezoidal block 5c contacts the first contact block 4c, the bottom of the vertical pushing seat 5b contacts the top flat end of the trapezoidal block 5c, so that when the trapezoidal block 5c pushes the first contact block 4c upward, the vertical pushing seat 5b has already driven the water flow pushing plate 6 to rise to the final position. The water flow pushing plate 6 and the guide rod 7 clamp the bottom horizontal section 8a. Before the clamping mechanism 2 squeezes the top horizontal section 8b, the clamping mechanism 2 does not extrude the dye on the top horizontal section 8b. After the clamping mechanism 2 continues to squeeze the top horizontal section 8b, the clamping mechanism 2 extrudes the dye on the top horizontal section 8b, that is, it avoids the squeezing roller 3 from horizontally pulling the top horizontal section 8b and prevents the fabric from being misaligned. At the same time, before the dye on the fabric is extruded, the liquid level of the dye has approached calm, avoiding the water flow pushing plate 6 splashing the dye when pushing the dye upward during the liquid squeezing of the textile fabric 8. When the trapezoidal block 5c is no longer in contact with the first contact block 4c as the linear displacement mechanism 4 moves downward, the first contact block 4c will pull the clamping mechanism 2 by gravity, so that the clamping mechanism 2 drives the squeezing roller 3 to reset to the initial position, and during the reset process of the squeezing roller 3, the top horizontal section 8b can be squeezed again.

[0042] If an electric control method is adopted to make the clamping mechanism 2 control the four squeezing rollers 3 to clamp the top horizontal section 8b, it will cause a pause of several seconds each time before squeezing the top horizontal section 8b, so that the two squeezing rollers 3 squeeze the top horizontal section 8b. After the squeezing is completed, it is necessary to make the squeezing rollers 3 release the squeezing of the top horizontal section 8b so that the textile fabric 8 can be pulled, which will waste a lot of time. Therefore, as Figures 3 - 7As shown, the clamping mechanism 2 includes two hinge seats 2f and two groups of grippers. Each two extrusion rollers 3 are installed on one gripper. The two grippers are fixedly connected by a connecting rod 2h, so that when one gripper moves, it can drive the other gripper to move synchronously. The two hinge seats 2f are both fixedly installed on one gripper. The two hinge rods 4a are hinged to the two hinge seats 2f respectively. When the hinge rod 4a is pushed, the hinge seat 2f will drive one gripper to move, and through the connecting rod 2h, the other gripper will be driven together. Each gripper includes a first mounting frame 2a, two sliding seats 2d, two sliding blocks 2e, four retaining bars 2c and four elastic stretching mechanisms 2b. Each two sliding blocks 2e are respectively installed at both ends of one extrusion roller 3, and the sliding block 2e is rotatably connected to the extrusion roller 3. Each two sliding blocks 2e are slidably installed on one sliding seat 2d vertically. The sliding seat 2d is fixedly installed on the first mounting frame 2a. The first mounting frame 2a is slidably installed on the box body 1 horizontally. The hinge seat 2f is fixedly connected to the first mounting frame 2a, that is, when the hinge seat 2f is pushed, the hinge seat 2f will drive the first mounting frame 2a to move horizontally. The four retaining bars 2c are all fixedly installed on the inner side of the box body 1 through mounting seats. It should be noted that when the first mounting frame 2a moves horizontally, it will not collide with the mounting seat. The ends of the two extrusion rollers 3 are both located inside the retaining bars 2c. The upper and lower two elastic stretching mechanisms 2b are used to pull the ends of the two extrusion rollers 3 to fit with the two retaining bars 2c respectively. The elastic stretching mechanism 2b is fixedly installed on the first mounting frame 2a. A groove 2c1 is opened at the end of the retaining bar 2c for the extrusion roller 3 to separate from the top horizontal section 8b. Among them, when the extrusion roller 3 contacts the bottom of the groove 2c1, the inner sides of the two extrusion rollers 3 are separated from the top horizontal section 8b. When the extrusion roller 3 contacts the inner end face of the retaining bar 2c, the two extrusion rollers 3 squeeze the top horizontal section 8b. When the first mounting frame 2a is pushed horizontally, the first mounting frame 2a will drive the two extrusion rollers 3 to move horizontally. The end of the extrusion roller 3 will slide horizontally along the groove 2c1, so that the extrusion roller 3 will slide upward along the groove 2c1, so that the two extrusion rollers 3 clamp the top horizontal section 8b. Since the top horizontal section 8b cannot be pushed, the two extrusion rollers 3 will squeeze out the dye on the top horizontal section 8b. When the extrusion roller 3 returns to the initial position, the elastic stretching mechanism 2b will pull the two extrusion rollers 3 to move outward, so that the two extrusion rollers 3 contact the groove 2c1. That is, before and after the two extrusion rollers 3 squeeze the top horizontal section 8b, the clamping mechanism 2 will not pause, saving the working time of the equipment. Moreover, according to the water absorption of the dye, the horizontal pushing mechanism 5a can be directly controlled to change the working speed of the whole equipment. For the textile fabric 8 with strong water absorption, the working speed of the horizontal pushing mechanism 5a is slowed down, while for the textile fabric 8 with weak water absorption, the working speed of the horizontal pushing mechanism 5a can be increased.And this structure can release the clamping of the textile fabric 8 at the initial position, enabling the textile fabric 8 to be pulled more smoothly by the pulling device along the guide rod 7, and reducing the resistance suffered by the guide rod 7 during this process.

[0043] In order to be able to pull the extrusion roller 3 into contact with the stop strip 2c and the extrusion roller 3 can still keep rotating. For this purpose, as Figure 5 shown, each elastic lifting mechanism 2b includes a swivel ring 2b1, a sliding column 2b2, a lifting spring 2b3 and a locking nut 2b4. The swivel ring 2b1 is fixedly installed at the end of the sliding column 2b2. The end of the extrusion roller 3 is inserted into the swivel ring 2b1. The sliding column 2b2 is slidably connected to the first mounting bracket 2a. The locking nut 2b4 is meshed and installed on the top of the sliding column 2b2. The lifting spring 2b3 is used to provide an elastic force away from the extrusion roller 3 to the locking nut 2b4. The lifting spring 2b3 is sleeved on the sliding column 2b2. One end of the lifting spring 2b3 abuts against the first mounting bracket 2a, and the other end of the lifting spring 2b3 abuts against the locking nut 2b4. Through the elastic force applied by the lifting spring 2b3, the swivel ring 2b1 can pull the extrusion roller 3 upward, enabling the extrusion roller 3 to be in contact with the stop strip 2c. And the end of the extrusion roller 3 can ensure rotation on the swivel ring 2b1.

[0044] In order to enable the first mounting bracket 2a to slide horizontally. For this purpose, as Figure 4 and Figure 7 shown, a slide rail 2s is fixedly arranged on the inner edge of the box body 1, and a slider 2j is fixedly arranged on the first mounting bracket 2a. The slider 2j is slidably connected to the slide rail 2s. When the first mounting bracket 2a moves, it will drive the slider 2j to slide along the slide rail 2s, that is, it realizes that the first mounting bracket 2a can slide horizontally.

[0045] As Figure 7 shown, an extension column is arranged on the hinge seat 2f. The extension column passes through the box body 1 and is fixedly connected to the first mounting bracket 2a. A kidney-shaped hole for the extension column to pass through is opened on the box body 1, so that when the hinge seat 2f is driven to move horizontally, the extension column can avoid colliding with the box body 1.

[0046] As Figure 8As shown, the vertical push seat 5b includes a mounting frame 2 5b2, a lower slide column 5b3, a contact block 2 5b4, four upper slide columns 5b5 and four guide seats 5b1, the guide seat 5b1 is fixedly mounted on the inner wall of the box body 1, one end of each two water flow push plates 6 is fixedly connected to one end of the two upper slide columns 5b5, the bottom of the four upper slide columns 5b5 is fixedly mounted on the mounting frame 2 5b2, the top of the lower slide column 5b3 is fixedly connected to the mounting frame 2 5b2, the lower slide column 5b3 is slidably connected to the box body 1, the contact block 2 5b4 is fixedly mounted on the bottom of the lower slide column 5b3, and the bottom of the contact block 2 5b4 contacts the trapezoidal block 5c. When the trapezoidal block 5c is pushed, the trapezoidal block 5c will push the contact block 2 5b4 to slide vertically, so that the contact block 2 5b4 pushes the lower slide column 5b3 upward, and the four upper slide columns 5b5 will slide vertically along the guide seat 5b1, which can drive the two water flow push plates 6 to move vertically upward. After the trapezoidal block 5c is reset, the water flow is driven by gravity to push the plate 6 downward to reset.

[0047] In order to be able to push the trapezoidal block 5c horizontally, for this purpose, Figure 9 As shown, the horizontal pushing mechanism 5a includes a pushing cylinder 5a1, a guide frame 5a3 and two guide posts 5a2, the guide frame 5a3 is fixedly mounted on the box body 1, the guide posts 5a2 can be horizontally slidably mounted on the guide frame 5a3, the trapezoidal block 5c is fixedly mounted on the ends of the two guide posts 5a2, the pushing cylinder 5a1 is fixedly mounted on the guide frame 5a3, and the output end of the pushing cylinder 5a1 is fixedly connected to the trapezoidal block 5c. By controlling the pushing cylinder 5a1 to work, the pushing cylinder 5a1 will push the trapezoidal block 5c to move horizontally, the trapezoidal block 5c will push up the contact block 2 5b4, so that the contact block 2 5b4 is pushed upward, and after the trapezoidal block 5c passes through the contact block 2 5b4, the inclined surface of the trapezoidal block 5c will push up the contact block 1 4c.

[0048] like Figure 9 As shown, the bottom of the box body 1 is fixedly provided with an elastic telescopic rod 1 9 and an elastic telescopic rod 2 10, the bottom of the elastic telescopic rod 1 9 abuts against the top of the contact block 2 5b4, and the bottom of the elastic telescopic rod 2 10 contacts the top of the contact block 1 4c. The elastic telescopic rod 1 9 and the elastic telescopic rod 2 10 work so that the elastic telescopic rod 1 9 and the elastic telescopic rod 2 10 push the contact block 1 4c and the contact block 2 5b4 downward, that is, the reset displacement of the water flow push plate 6 and the clamping mechanism 2 is no longer driven only by gravity, but can be driven by the elastic force applied by the elastic telescopic rod 1 9 and the elastic telescopic rod 2 10, that is, the reset speed is increased.

[0049] The printing and dyeing method of the same-bath textile printing and dyeing equipment is characterized by comprising the following steps:

[0050] Step 1: The dye is pushed toward the bottom horizontal section 8a, and the water flow pushes the plate 6 to press the bottom horizontal section 8a;

[0051] The horizontal pushing mechanism 5a pushes horizontally, and the trapezoidal block 5c pushes the vertical pushing seat 5b to move upward, so that the water flow pushing plate 6 moves upward. The water flow pushing plate 6 pushes the dye towards the bottom horizontal section 8a, enabling the dye to better penetrate the bottom horizontal section 8a. Finally, the water flow pushing plate 6 presses the bottom horizontal section 8a against the guiding rod 7.

[0052] Step Two: The clamping mechanism 2 drives the extrusion roller 3 to reciprocate, squeezing out the dye on the top horizontal section 8b.

[0053] As the horizontal pushing mechanism 5a continues to move horizontally, the horizontal pushing mechanism 5a pushes the contact block one 4c upward, causing the hinged rod 4a to push the clamping mechanism 2 to move to the left. The two extrusion rollers 3 slide inward along the groove 2c1 to squeeze the top horizontal section 8b. As the clamping mechanism 2 continues to move, the dye on the top horizontal section 8b is squeezed out. Subsequently, the horizontal pushing mechanism 5a performs a reset movement. Due to the self - weight of the linear pushing mechanism 4 and the elastic force exerted by the elastic telescopic rod two 10, the hinged rod 4a pulls the clamping mechanism 2 to move rightward for reset. The two extrusion rollers 3 squeeze the top horizontal section 8b again, squeezing out the dye on the top horizontal section 8b that was not squeezed out before.

[0054] Step Three: The water flow pushing plate 6 releases the pressing on the bottom horizontal section 8a.

[0055] The horizontal pushing mechanism 5a pulls the trapezoidal block 5c to reset. When the trapezoidal block 5c separates from the vertical pushing seat 5b, due to the gravity of the vertical pushing seat 5b and the downward elastic force of the elastic telescopic rod two 10, the water flow pushing plate 6 is pulled downward, that is, it releases the pressing on the bottom horizontal section 8a and generates a downward suction force, enabling the dye above the bottom horizontal section 8a to better penetrate the bottom horizontal section 8a.

[0056] Step Four: Pull the textile fabric 8.

[0057] When the extrusion roller 3 returns to contact with the groove 2c1, the two extrusion rollers 3 separate from the top horizontal section 8b, and the water flow pushing plate 6 releases the pressing on the bottom horizontal section 8a. At this time, the driving mechanism outside the box body 1 pulls the textile fabric 8 to move along the guiding rod 7.

[0058] The co-bath textile printing and dyeing equipment and the printing and dyeing method can drive the water flow pushing plate 6 to move up and down, so that the dye can better penetrate the bottom horizontal section 8a, and the printing and dyeing effect of the textile fabric 8 is better. And when the clamping mechanism 2 drives the extrusion roller 3 to extrude the top horizontal section 8b, the water flow pushing plate 6 can automatically press the bottom horizontal section 8a tightly, avoiding the textile fabric 8 being pulled and offset by the extrusion roller 3 and ensuring the flatness of the fabric. And through one-time pushing by the horizontal pushing mechanism 5a, the water flow pushing plate 6 can pre-press the bottom horizontal section 8a, and at the same time, the two extrusion rollers 3 can reciprocally extrude the dye on the top horizontal section 8b. The whole process is relatively smooth, and the clamping mechanism 2 will not pause before and after the two extrusion rollers 3 extrude the top horizontal section 8b, saving the working time of the equipment.

[0059] Moreover, according to the water absorbency of the dye, the working speed of the horizontal pushing mechanism 5a can be directly controlled, that is, the working speed of the whole equipment can be changed. For the textile fabric 8 with strong water absorbency, the working speed of the horizontal pushing mechanism 5a slows down, while for the textile fabric 8 with weak water absorbency, the working speed of the horizontal pushing mechanism 5a can be increased. And when the extrusion roller 3 is in the initial position, it can release the clamping of the textile fabric 8, so that the textile fabric 8 can be more smoothly pulled along the guide roller 7 by the pulling device, reducing the resistance received by the guide roller 7 in this process.

[0060] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
