Description

Technical Field

[0001] This invention relates to the field of textile dyeing technology, and more specifically to a dyeing apparatus for textile production. Background Technology

[0002] Textile dyeing is a technique that uses dyes to color and process fabrics. It generally refers to the dyeing techniques for textiles and can be divided into traditional dyeing techniques and modern dyeing techniques. In order to achieve even dyeing of multiple components and improve color uniformity and fastness, new dyeing processes need to be developed, especially controlling the heating process and adjusting the pH value in the dye bath. Currently, there are many auxiliaries available for controlling pH value. Most of them use the heating process to make the pH value slide from alkaline to neutral and acidic, and some slide in the opposite direction. This is very effective for dyeing pH-sensitive fibers and dyes, not only reducing damage to fibers and dyes, but also improving dyeing rate, color uniformity, evenness, and color fastness. We use this principle to allow reactive dyes and acid dyes to be used together in the dye bath to dye cotton and nylon fabrics. We also utilize the properties of hydrolyzed dyes, which are acid dyes, to dye nylon in acidic media, making full use of the dyes and reducing the amount of hydrolyzed dyes in wastewater.

[0003] In the existing technology, during the dyeing process of textile fabrics, it is necessary to adjust the height of the tension roller to keep it taut and prevent wrinkles. However, when dyeing thinner textile fabrics, since the height of the tension roller can be adjusted but its position cannot be moved, the tension may be unevenly distributed due to the longer tension distance, causing the fabric to roll up. In this case, the dyed fabric may have uneven color distribution due to insufficient dyeing, which may affect the dyeing effect of the textile fabric. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a dyeing apparatus for textile production to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A dyeing device for textile production includes a dyeing vat. First fixing plates are fixedly installed on both sides of one end of the dyeing vat. A placement rod is arranged between the two first fixing plates. A placement sleeve is movably sleeved on the outer circular wall of the placement rod. Two electric hydraulic cylinders are fixedly installed on both sides of the dyeing vat. A mounting plate is provided on the top surface of the dyeing vat. The top of the telescopic rod of the electric hydraulic cylinder is fixedly installed to the mounting plate. Several heating rods are fixedly installed on both sides of the inside of the dyeing vat.

[0007] A first mounting bracket is fixedly mounted on the top surface of the mounting plate. A first motor is fixedly mounted on the top surface of the first mounting bracket. The drive shaft of the first motor passes through the first mounting bracket. A lead screw is rotatably connected to the top surface of the mounting plate. A first coupling is fixedly sleeved on the outer circular wall of the lead screw. The inner circular wall of the first coupling is fixedly sleeved with the drive shaft of the first motor. A first connecting plate is provided between the mounting plate and the first mounting bracket. A threaded hole is opened on the top surface of the first connecting plate. The threaded hole is threadedly connected to the lead screw.

[0008] A plurality of first connecting posts are fixedly installed on the bottom surface of the first connecting plate, with three first connecting posts forming a group. A plurality of first positioning holes are opened on the top surface of the mounting plate, and the first positioning holes are slidably connected to the first connecting posts. Two second mounting shells are provided on the bottom surface of the mounting plate, and tension rollers are rotatably connected inside the two second mounting shells. The top surface of the second mounting shells is fixedly installed to the first connecting posts. Two first mounting plates are fixedly installed on the bottom surface of the mounting plate, and a placement roller is rotatably connected between the two first mounting plates.

[0009] A plurality of mounting sleeves are provided on the top surface of the mounting plate. The outer circular wall of the mounting sleeve is fixedly installed to the first connecting plate. A plurality of second positioning holes are provided on the top surface of the mounting plate. The second positioning holes are slidably connected to the mounting sleeves. A threaded column is rotatably connected inside the mounting sleeve. An adjusting block is fixedly installed on the top surface of the threaded column. An adjusting column is slidably connected inside the mounting sleeve. A threaded groove is provided on the top surface of the adjusting column. The threaded groove is threadedly connected to the threaded column. A plurality of first mounting shells are provided on the bottom surface of the mounting plate. The top surface of the first mounting shell is fixedly installed to the adjusting column. An auxiliary pressure roller is rotatably connected inside each of the plurality of first mounting shells.

[0010] A winding assembly is disposed on both sides of the dyeing vat and is used to wind up the dyed textile fabric.

[0011] By adopting the above technical solution, during use, the operator places the placement sleeve containing the textile fabric over the outside of the placement rod, passes the textile fabric through the top of the placement roller, and then wraps it around the surface of the take-up assembly. The operator then uses the first motor, whose drive shaft rotates, causing the lead screw to rotate. Under the threaded transmission of the lead screw, the first connecting plate moves the two tension rollers downwards, pressing down on the textile fabric to generate tension. When the textile fabric curls at both ends due to the tension, the operator rotates multiple adjusting blocks. The rotation of these adjusting blocks then drives the threaded column to rotate. Under the threaded transmission of the threaded column and the threaded groove, the adjusting column extends from inside the mounting sleeve. During this process, the movement of multiple adjusting columns drives multiple auxiliary... The pressure rollers move downwards, causing multiple auxiliary pressure rollers to press down on both sides of the fabric. This downward pressure disperses the tension on both sides of the fabric, resulting in a more balanced tension and eliminating edge curling. After these steps, workers use multiple heating rods to heat the dye inside the dyeing vat. Then, workers use multiple electric hydraulic cylinders and a winding assembly. The retraction of the cylinders pulls the mounting plate and the fabric underneath it into the dyeing vat for dyeing. Simultaneously, the winding assembly winds up the dyed fabric, thus achieving the effect of dyeing the fabric and preventing edge curling due to uneven surface tension during the dyeing process.

[0012] Preferably, the winding assembly includes two second fixing plates, which are respectively fixedly installed on both sides of the dyeing vat. A winding rod is disposed between the two second fixing plates. A second mounting plate is rotatably connected to the outer circular wall of the winding rod. The second mounting plate is connected and fixed to the second fixing plates by bolts. A winding sleeve is movably sleeved on the outer wall of the winding rod. A limit sleeve and a positioning post are rotatably connected inside the two second fixing plates, respectively. The inner wall of the limit sleeve is movably sleeved with the winding rod. An insert is fixedly installed at one end of the winding rod. A limit groove is formed at one end of the positioning post. The inner wall of the limit groove is movably sleeved with the insert. A second motor is fixedly installed on one side of the second fixing plate. The drive shaft of the second motor passes through the second fixing plate. A first pulley is fixedly installed at one end of the drive shaft of the second motor. A second pulley is fixedly installed at one end of the positioning post. The first pulley and the second pulley are connected by a first transmission belt.

[0013] By adopting the above technical solution, when the worker winds up the textile fabric, the worker uses a second motor. The rotation of the drive shaft of the second motor drives the first pulley to rotate. Then, under the belt drive of the first pulley and the first transmission belt, the second pulley drives the positioning post, the winding rod, and the winding sleeve to rotate. At this time, the rotating winding sleeve winds up the textile fabric. After the textile fabric on the surface of the winding sleeve is wound up, the worker releases the fixing of the winding rod through the second mounting plate. At this time, the worker can pull out the winding rod, and at the same time, the insert will move out of the limiting groove inside the positioning post, thereby releasing the winding sleeve that was fixed by the winding rod. Then, the worker can remove the winding sleeve and the textile fabric wound on its surface, thus achieving the effect of winding up the textile fabric and making it easy to remove the textile fabric after winding.

[0014] Preferably, the dyeing vat has several rotating shafts rotatably connected inside, and several mounting sleeves are fixedly sleeved on the outer circular walls of the rotating shafts. Several stirring plates are fixedly installed on the outer circular walls of the mounting sleeves. A fixed bracket is fixedly installed on one side of the dyeing vat, and a third motor is fixedly installed on one side of the fixed bracket. A second coupling is fixedly sleeved on the outer circular wall of the drive shaft of the third motor. The inner circular wall of the second coupling is fixedly sleeved with the rotating shaft. A third pulley is fixedly sleeved on the outer circular walls of the rotating shafts. The third pulleys are connected by a second transmission belt. Two pressure rollers are fixedly installed on one side of the dyeing vat, and the inner wall of the pressure rollers is movably sleeved with the second transmission belt.

[0015] By adopting the above technical solution, when the textile fabric is dyed inside the dyeing vat, the worker uses a third motor. The drive shaft of the third motor rotates, which drives the third pulley to rotate. Then, under the belt drive of multiple third pulleys and the second transmission belt, multiple rotating shafts will rotate. At this time, the rotating shafts will drive multiple stirring plates on their surfaces to rotate. In turn, the stirring plates will agitate the dye inside the dyeing vat, thereby preventing the dye inside the dyeing vat from settling to the bottom.

[0016] Preferably, two mounting seats are fixedly installed on both sides of the dyeing vat, and a second connecting plate is provided on the top surface of several mounting seats. Every two second connecting plates form a group, and an auxiliary support roller is rotatably connected between the two second connecting plates. A spring is movably sleeved inside the mounting seat, and a second connecting column is movably sleeved inside the mounting seat. The top surface of the second connecting column is fixedly installed with the second connecting plate.

[0017] By adopting the above technical solution, when the textile fabric is dyed, the two auxiliary support rollers will provide auxiliary support to the textile fabric under the action of the spring rebound force, thereby preventing the textile fabric from being scratched on the surface of the dyeing vat.

[0018] Preferably, each of the mounting bases has two guide holes on its top surface, and each of the second connecting plates has two guide posts fixedly mounted on its bottom surface, with the guide posts slidably connected to the guide holes.

[0019] By adopting the above technical solution, it is easy to guide and limit the second connecting plate, thereby preventing the auxiliary support roller from deviating during use.

[0020] Preferably, a support frame is fixedly installed on one side of the dyeing vat, a hot air blower is fixedly installed on the top surface of the support frame, a connecting pipe is fixedly sleeved on the inner circular wall of the hot air blower outlet, two air boxes are fixedly installed on the top surface of the dyeing vat, a dustproof net is fixedly installed inside the two air boxes, and the top surface of the two air boxes is fixedly installed with the connecting pipe.

[0021] By adopting the above technical solution, when the textile fabric is being dyed, the staff uses a hot air blower, which draws hot air into the interior of two air boxes through connecting pipes. The hot air inside the air boxes is then blown directly onto the surface of the textile fabric, which facilitates preheating of the textile fabric before dyeing and drying of the textile fabric after dyeing.

[0022] Preferably, two support rods are fixedly installed on one side of the dyeing vat, and the inner wall of the support rods is movably connected to the connecting pipe.

[0023] By adopting the above technical solution, it is easy to support and fix the connecting pipe.

[0024] Preferably, a second protective cover is rotatably connected to one side of the dyeing vat, and a first protective cover is fixedly installed on one side of the second fixing plate.

[0025] By adopting the above technical solution, the second and first transmission belts are prevented from falling off due to foreign objects during use.

[0026] In summary, the present invention has the following main beneficial effects:

[0027] By using a first motor, the drive shaft of the first motor rotates, driving two tension rollers to move downwards and press down on the textile fabric to generate tension. When the textile fabric curls at both sides due to the tension, multiple adjusting blocks are rotated to drive the threaded columns to rotate. The adjusting columns then extend from inside the mounting sleeve. At this time, the movement of the multiple adjusting columns drives multiple auxiliary pressure rollers to move downwards and press down on both sides of the textile fabric. The downward pressure of the multiple auxiliary pressure rollers can disperse the tension on both sides of the textile fabric, thereby adjusting the tension on the surface of the textile fabric to a more balanced state and eliminating the curling phenomenon on both sides of the textile fabric. This achieves the effect of dyeing the textile fabric and preventing the curling phenomenon caused by uneven surface tension during the dyeing process. Attached Figure Description

A first connecting plate 6 is provided between the mounting plate 5 and the first mounting bracket 7. A threaded hole is opened on the top surface of the first connecting plate 6, and the threaded hole is threadedly connected to the lead screw 20. Several first connecting posts 22 are fixedly installed on the bottom surface of the first connecting plate 6, with three first connecting posts 22 forming a group. The top surface of mounting plate 5 has several first positioning holes 23, which are slidably connected to the first connecting post 22. The bottom surface of mounting plate 5 has two second mounting shells 28, each with a tension roller 29 rotatably connected inside. The top surface of the second mounting shells 28 is fixedly installed to the first connecting post 22. The bottom surface of mounting plate 5 has two first mounting plates 30 fixedly installed, with a placement roller 31 rotatably connected between them. Several mounting sleeves 24 are also provided on the top surface of mounting plate 5, with the outer circular wall of each sleeve fixedly installed to the first connecting plate 6.

An adjusting column 32 is slidably connected to the inside of the mounting sleeve 24. The adjusting column 32 has a threaded groove 33 on its top surface. The threaded groove 33 is threadedly connected to the threaded column 34. The mounting plate 5 has several first mounting shells 26 on its bottom surface. The top surface of the first mounting shells 26 is fixedly installed to the adjusting column 32. The interior of each of the several first mounting shells 26 is rotatably connected to an auxiliary pressure roller 27.The winding assembly is located on both sides of the dyeing vat 1 and is used to wind up the dyed fabric. In use, the operator places the placement sleeve 2 containing the fabric onto the outside of the placement rod 36, passes the fabric through the top of the placement roller 31, and then winds it around the surface of the winding assembly. The operator then uses the first motor 19, whose drive shaft rotates, causing the lead screw 20 to rotate. Under the threaded transmission of the lead screw 20, the first connecting plate 6 drives the two tension rollers 29 downwards, pressing down on the fabric to generate tension. When the fabric curls at both ends due to the tension, the operator rotates multiple adjusting blocks 35. The rotation of the adjusting blocks 35 drives the threaded column 34 to rotate. Then, under the threaded transmission of the threaded column 34 and the threaded groove 33, the adjusting column 32 extends from inside the mounting sleeve 24. During this process, the movement of multiple adjusting columns 32 causes multiple auxiliary pressure rollers 27 to move downwards, which in turn press down on both sides of the textile fabric. The downward pressure of the auxiliary pressure rollers 27 disperses the tension on both sides of the textile fabric, thereby adjusting the tension on the surface of the textile fabric to a more balanced state and eliminating the curling phenomenon on both sides of the textile fabric. After the above steps are completed, the operator uses multiple heating rods 16 to heat the dye inside the dyeing vat 1. Then, the operator uses multiple electric hydraulic cylinders 4 and a winding assembly. The retraction of the telescopic rods of the multiple electric hydraulic cylinders 4 drives the mounting plate 5 and the textile fabric at its bottom into the dyeing vat 1 for dyeing. At the same time, the winding assembly winds up the dyed textile fabric, thus achieving the effect of dyeing the textile fabric and preventing the curling phenomenon caused by uneven surface tension during the dyeing process.

When the worker rolls up the textile fabric, the worker uses the second motor 41, and the rotation of the drive shaft of the second motor 41 drives the first pulley 42 to rotate. Then, under the belt drive of the first pulley 42 and the first transmission belt 44, the second pulley 43 drives the positioning post 39, the winding rod 37, and the winding sleeve 3 to rotate.

[0048] Example 4

[0049] Based on the above embodiments one, two, or three, and referring to... Figure 1 , Figure 2 , Figure 7 and Figure 10 A support frame 14 is fixedly installed on one side of the dyeing vat 1.

The top surfaces of the two air boxes 10 are fixedly installed with the connecting pipe 12. When the textile is being dyed, the worker uses the hot air blower 13, which then draws hot air into the two air boxes 10 through the connecting pipe 12.

[0050] Working principle: Please refer to Figures 1-12 As shown, in use, the operator places the placement sleeve 2 containing the textile fabric onto the outside of the placement rod 36, passes the textile fabric through the top of the placement roller 31, and then wraps it around the surface of the winding assembly. The operator then uses the first motor 19, whose drive shaft rotates, causing the lead screw 20 to rotate. Under the threaded transmission of the lead screw 20, the first connecting plate 6 drives the two tension rollers 29 downwards, pressing down on the textile fabric to generate tension. When the textile fabric curls at both ends due to the tension, the operator rotates multiple adjusting blocks 35. The rotation of the adjusting blocks 35 causes the threaded column 34 to rotate. Under the threaded transmission of the threaded column 34 and the threaded groove 33, the adjusting column 32 extends out from inside the mounting sleeve 24. During this process, the multiple adjusting columns 32 move... This will drive multiple auxiliary pressure rollers 27 to move downwards, which will then press down on both sides of the textile fabric. The downward pressure of the multiple auxiliary pressure rollers 27 can disperse the tension on both sides of the textile fabric, thereby adjusting the tension on the surface of the textile fabric to a more balanced state and eliminating the curling phenomenon on both sides of the textile fabric. After the above steps are completed, the staff uses multiple heating rods 16 to heat the dye inside the dyeing vat 1. Then, the staff uses multiple electric hydraulic cylinders 4 and a winding assembly. The extension rods of the multiple electric hydraulic cylinders 4 will retract, which will drive the mounting plate 5 and the textile fabric at its bottom into the dyeing vat 1 for dyeing. At the same time, the winding assembly will wind up the dyed textile fabric, thereby achieving the effect of dyeing the textile fabric and preventing the curling phenomenon of the textile fabric due to uneven surface tension during the dyeing process.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
