Description

Technical Field

[0001] This utility model relates to the field of dyeing apparatus technology, and in particular to a dyeing apparatus for dispersible reactive dyes in the same bath. Background Technology

[0002] Co-dyeing refers to placing different types of fiber fabrics into the same dye bath, allowing them to absorb dye together. This method can improve dyeing efficiency and reduce energy consumption and wastewater discharge during the dyeing process.

[0003] Chinese Patent No. CN217378251U discloses a low-emission simultaneous dyeing device for cotton fabrics. This technical solution includes a dyeing vat, a first guide wheel, a second guide wheel, a first impregnation wheel, a second impregnation wheel, and a third impregnation wheel. The dyeing vat opens upwards, and the first, second, and third impregnation wheels are rotatably disposed within it. A drain valve pipe is fixed to the lower end wall of the dyeing vat, and support feet are fixed to the four corners of the lower end of the vat. The first and second guide wheels are symmetrically rotatably disposed on the dyeing vat. A star roller rotates within the dyeing vat, positioned between the first, second, and third impregnation wheels. This technical solution utilizes the intermittent pushing of the rollers on the cotton fabric to achieve a certain degree of orderly intermittent tension and relaxation of the cotton fibers, allowing the dye to penetrate the cotton fabric more quickly and improving dyeing efficiency.

[0004] However, the above technical solution has the following shortcomings: during dyeing, the dye will accumulate on the immersion wheel, which is located inside the dyeing vat, making it difficult to clean. If it is not cleaned, different dyes may interfere with each other, affecting the dyeing effect of the fabric. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a disperse reactive dyeing device that uses motors b and a to adjust the positions of guide rollers b, c, and cleaning rollers, allowing the items to be cleaned to be moved to the vicinity of the top of the dyeing vat, thereby reducing the amount of residual dye at the contact point between the device and the fabric.

[0006] The present invention provides a dispersible reactive dye co-bath dyeing device, comprising: a dyeing vat with a squeezing assembly at its top and a guide roller a at its top; a guide assembly consisting of two sets arranged opposite each other on the dyeing vat, the guide assembly including a motor a on the dyeing vat, a movable frame at the output end of the motor a, and a guide roller b rotatably mounted on the movable frame; and a steering assembly including a motor b on the dyeing vat, a rotating frame at the output end of the motor b, a guide roller c and a cleaning roller rotatably mounted at both ends of the rotating frame, and a plurality of cleaning brushes arranged in a ring on the cleaning roller.

[0007] Preferably, a drive frame is provided on the dyeing vat, a motor c is provided on the drive frame, a gear a is provided at the output end of the motor c, a fixed cover is threadedly connected to the drive frame, an intermediate bearing is provided on the fixed cover, a drive rod is detachably provided between the intermediate bearing and the cleaning roller, a gear b and an abutment ring are slidably provided on the drive rod, a bearing is provided between the abutment ring and the dyeing vat, and gear a and gear b are meshed together.

[0008] Preferably, the drive rod includes a cylindrical rod portion and a rectangular rod portion connected to each other. The rectangular rod portion is connected to an intermediate bearing. The gear b and the abutment ring are slidably distributed on the rectangular rod portion, and the two ends of the gear b abut against the abutment ring and the cylindrical rod portion, respectively.

[0009] Preferably, the dyeing vat is provided with two relatively distributed inclined plates, and a heating component is provided between the dyeing vat and the inclined plates.

[0010] Preferably, the squeezing assembly includes a squeezing frame mounted on the dyeing vat, an electric cylinder mounted on the squeezing frame, an adjusting frame mounted on the output end of the electric cylinder, multiple squeezing rollers rotatably mounted on the adjusting frame, and a guide roller d rotatably mounted on the dyeing vat.

[0011] Preferably, the dyeing vat has two shielding covers that rotate in opposite directions at the top.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] In use, the fabric moves on guide rollers a, b, c, and the squeezing assembly. Under the action of an external driving source, the fabric moves inside the dyeing vat. When the dyeing process is complete and the dyeing vat needs to be cleaned, motor a drives the movable frame to rotate, moving guide roller b to the vicinity of the top of the dyeing vat. Then, motor b drives the rotating frame to rotate, moving the cleaning roller to the vicinity of the top of the dyeing vat. This reduces the difficulty for users to clean guide rollers b, c, and the cleaning roller, and avoids interference from residual dye on the dyeing of the fabric. Attached Figure Description

[0019] Example 1

[0020] like Figures 1-4 As shown in this embodiment, a disperse reactive dye co-bath dyeing device includes a dyeing vat 1, a guiding assembly, and an adjusting assembly. A squeezing assembly 12 is provided at the top of the dyeing vat 1, and a guide roller a3 is also provided at the top of the dyeing vat 1. Two sets of guiding assemblies are arranged opposite each other on the dyeing vat 1. The guiding assembly includes a motor a4 provided on the dyeing vat 1, a movable frame 5 provided at the output end of the motor a4, and a guide roller b6 rotatably provided on the movable frame 5. The adjusting assembly includes a motor b provided on the dyeing vat 1, a rotating frame 7 provided at the output end of the motor b, a guide roller c8 and a cleaning roller 9 rotatably provided at both ends of the rotating frame 7, and a plurality of cleaning brushes 10 arranged in a ring on the cleaning roller 9.

[0021] In this embodiment, the fabric moves on guide rollers a3, b6, c8, and the squeezing assembly 12. Under the action of an external driving source, the fabric moves inside the dyeing vat 1. When the dyeing of the fabric is completed and the inside of the dyeing vat 1 needs to be cleaned, motor a4 drives the movable frame 5 to rotate, moving guide roller b6 to near the top of the dyeing vat 1. Then, motor b drives the rotating frame 7 to rotate, moving the cleaning roller 9 to near the top of the dyeing vat 1. This reduces the difficulty for the user to clean guide rollers b6, c8, and 9, and avoids interference from residual dye on the dyeing of the fabric.

[0022] Example 2

[0023] like Figure 1 and Figure 4As shown in the figure, the disperse reactive dye co-bath dyeing device proposed in this embodiment, compared with the first embodiment, in this embodiment, the dyeing vat 1 is provided with a drive frame 20, the drive frame 20 is provided with a motor c13, the output end of the motor c13 is provided with a gear a14, the drive frame 20 is threadedly connected with a fixing cover 16, the fixing cover 16 is provided with an intermediate bearing 17, the intermediate bearing 17 and the cleaning roller 9 are detachably provided with a drive rod 15, the drive rod 15 is slidably provided with a gear b18 and an abutment ring 19, the abutment ring 19 and the dyeing vat 1 are provided with a bearing, and the gear a14 and the gear b18 are meshed and connected.

[0024] When the cleaning roller 9 needs to be driven to rotate, the dye inside the dyeing vat 1 needs to be drained in advance. The abutment ring 19 and gear b18 are placed between the drive frame 20 and the dyeing vat 1, and the abutment ring 19 is fixed to the bearing with bolts. The drive rod 15 passes through the abutment ring 19, gear b18 and dyeing vat 1 in sequence. A sealing gasket is provided between the abutment ring 19 and the bearing. A waterproof mechanism is provided between the bearing and the dyeing vat 1 to prevent liquid from overflowing from the bearing into the dyeing vat 1. The drive rod 15 is connected to the cleaning roller 9 by axial abutment, which reduces the difficulty of installing the drive rod 15 and the difficulty of adjusting the position of the cleaning roller 9.

[0025] The drive rod 15 includes a cylindrical rod portion 151 and a rectangular rod portion 152 connected to each other. The rectangular rod portion 152 is connected to the intermediate bearing 17. The gear b18 and the abutment ring 19 are both slidably distributed on the rectangular rod portion 152. The two ends of the gear b18 abut against the abutment ring 19 and the cylindrical rod portion 151, respectively. The two ends of the drive rod 15 are connected to the intermediate bearing 17 and the cleaning roller 9, respectively. The rectangular rod portion 152 abuts axially against the gear b18, thereby allowing the gear b18 to drive the drive rod 15 to rotate.

[0026] Example 3

[0027] like Figures 1-3 As shown in this embodiment, a disperse reactive dye co-bath dyeing device is proposed. Compared with the first embodiment, in this embodiment, two relatively distributed inclined plates 11 are provided on the dyeing vat 1. A heating component is provided between the dyeing vat 1 and the inclined plates 11. During the accumulation process of the dye, the inclined plates 11 will cause the dye to accumulate towards the cleaning roller 9, so that the cleaning roller 9 can mix the dye with the liquid, improve the dyeing effect of the liquid, and the heating component can ensure that the temperature of the liquid is at a temperature that is easy to dye, thus improving the dyeing effect of the fabric.

[0028] The extrusion assembly 12 includes an extrusion frame 121 mounted on the dyeing vat 1, an electric cylinder 122 mounted on the extrusion frame 121, an adjustment frame 123 mounted on the output end of the electric cylinder 122, multiple extrusion rollers 124 rotatably mounted on the adjustment frame 123, and a guide roller d125 rotatably mounted on the dyeing vat 1. When the fabric moves out of the dyeing vat 1, the electric cylinder 122 drives the adjustment frame 123 to move, adjusting the distance between the extrusion rollers 124 and the guide roller d125, so that the amount of dye liquid on the fabric is reduced during the extrusion process, thereby increasing the drying speed of the fabric. Furthermore, the extruded dye can be used for repeated dyeing, thereby improving the utilization rate of the dye.

[0029] Two shielding covers 2 are installed at the top of the dyeing vat 1, rotating in opposite directions. The shielding covers 2 reduce the contact area between the dyeing vat 1 and the external environment, thereby reducing the rate of heat loss inside the dyeing vat 1.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
