Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing equipment technology, and more specifically, to a printing and dyeing device for textile fabrics. Background Technology

[0002] Fabric dyeing equipment is a specialized piece of equipment used in the textile industry to dye fabrics. Its core objective is to apply dyes evenly and firmly to the fibers through physical and chemical processes, thereby changing the color of the fabric. Fabric dyeing equipment typically includes a dyeing tank, which is equipped with a stirring device.

[0003] A mixing device typically includes a rotating shaft and several mixing rods fixed on the rotating shaft. The mixing rods continuously stir the fabric into the dye to ensure the dyeing efficiency of the fabric. However, during the operation of the mixing device, the fabric may become entangled on the mixing rods. This will prevent the entangled parts of the fabric from fully contacting the dye, affecting the overall dyeing effect of the fabric.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dyeing and printing device for textile fabrics.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a textile dyeing device, comprising a horizontally arranged dyeing tank, a rotating shaft rotatably connected to the dyeing tank along the axis of the dyeing tank, a stirring rod fixed on the outer peripheral wall of the rotating shaft, a partition net that allows only dye to pass through the dyeing tank, a dyeing chamber and a drainage chamber located on both sides of the partition net, the stirring rod being only located in the dyeing chamber, a drainage pipe connected to the side wall of the drainage chamber, the other end of the drainage pipe being connected to the rotating shaft, a reflux chamber being provided in both the rotating shaft and the stirring rod, a water outlet communicating with the reflux chamber being provided on the stirring rod, and a pump for pumping the dye out of the water outlet being provided on the drainage pipe.

[0007] The present invention is further configured such that: a filter screen is provided in the drain pipe, and an inspection port for the filter screen to pass through is provided on the side wall of the drain pipe, and a sealing cap is detachably connected to the inspection port.

[0008] The present invention is further configured such that the inspection port is located near the connection between the drain pipe and the rotating shaft.

[0009] The present invention is further configured such that: the separating net includes a net body and a support, and the support is provided with a sealed bearing that is rotatably connected to the outer peripheral wall of the rotating shaft.

[0010] The present invention is further configured such that the opening area of ​​the water outlet on the stirring rod is smaller than the opening area at the connection between the water outlet and the reflux chamber.

[0011] The present invention is further configured such that: the filter screen includes a reinforcing frame and a mesh sheet, and the reinforcing frame is disposed on the side of the filter screen facing away from the rotating shaft.

[0012] The present invention is further configured such that the mesh is mounted on the reinforcing frame by fixing screws.

[0013] In summary, this utility model has the following beneficial effects: When the dyeing and printing equipment is in operation, the drive motor drives the rotating shaft to rotate, which in turn drives the stirring rod to rotate along the central axis of the dyeing tank. The stirring rod continuously stirs the fabric into the dye, while the pump draws some of the dye into the return chamber and presses it out from the outlet. This design prevents the fabric from easily tangling on the stirring rod under the impact of the dye. At the same time, the dye pressed out from the outlet can also dye the fabric, improving the dyeing and printing efficiency. The pump continuously presses the dye out from the outlet and brings it into contact with the fabric, allowing the dye to circulate continuously in the dyeing tank, improving the utilization rate of the dye and reducing the possibility of dye forming clumps due to sedimentation. Pneumatic diaphragm pumps are preferred for the pump. Pneumatic diaphragm pumps can reduce the contact area between the pump body parts and the dye, reduce the possibility of the pump being corroded by the dye, and improve the service life of the pump. The partition screen can block the fabric and prevent it from being sucked into the drain pipe and causing blockage under the force of the pump. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Textile dyeing and printing equipment, such as Figure 1 and Figure 3 As shown, the apparatus includes a horizontally arranged dyeing tank 1, with a rotating shaft 2 rotatably connected to the dyeing tank 1 along its axial direction. A frame is fixed to one end of the dyeing tank 1, and a drive motor 18 is fixedly mounted on the frame. The output end of the drive motor 18 passes through the dyeing tank 1 and is fixedly connected to one end of the rotating shaft 2. The output end of the drive motor 18 is sealed to the dyeing tank 1. A stirring rod 3 is welded to the outer peripheral wall of the rotating shaft 2. A partition screen that only allows dye to pass through is provided in the dyeing tank 1. The dyeing tank 1 has a dyeing chamber 101 and a drainage chamber 102 located on both sides of the partition screen. The stirring rod 3 is only located in the dyeing chamber 101. A drain pipe 4 is connected to the side wall of the drain chamber 102. The other end of the drain pipe 4 passes through the dyeing tank 1 and is connected to the end of the rotating shaft 2 facing away from the drive motor 18. Both the rotating shaft 2 and the stirring rod 3 have reflux chambers 5. The stirring rod 3 has an outlet 6 that connects to the reflux chamber 5. The drain pipe 4 is equipped with a pump 7 for discharging dye from the outlet 6. Specifically, the drain pipe 4 and the rotating shaft 2 are connected to each other by a mechanical seal. The mechanical seal is a conventional end-face mechanical seal structure in the art, including a stationary ring 17 sealed and installed on the dyeing tank 1 and a moving ring 16 fixedly installed on the end of the rotating shaft 2. The end of the drain pipe 4 passes through the middle of the stationary ring 17. This design not only ensures the sealing of the connection between the drain pipe 4 and the rotating shaft 2, but also ensures the sealing of the drain pipe 4 as it passes through the dyeing tank 1. When the dyeing device is running, the drive motor 18 drives the rotating shaft 2 to rotate, causing the rotating shaft 2 to drive the stirring rod 3 to rotate along the central axis of the dyeing tank 1. This causes the stirring rod 3 to continuously stir the fabric into the dye, while the liquid pump 7 draws some of the dye into the return chamber 5 and presses it out from the outlet 6. This design makes it less likely for the fabric to entangle on the stirring rod 3 under the impact of the dye. At the same time, the dye pressed out from the outlet 6 can also dye the fabric. To improve the dyeing efficiency of fabrics, the pump 7 continuously pushes the dye out of the outlet 6 and into contact with the fabric, allowing the dye to circulate continuously in the dyeing tank 1, thus improving the dye utilization rate and reducing the possibility of dye forming clumps due to sedimentation. A pneumatic diaphragm pump is preferred for the pump 7, as it reduces the contact area between the pump parts and the dye, lowering the possibility of dye corrosion and extending the pump 7's service life. The partition mesh acts as a barrier, preventing the fabric from being sucked into the drain pipe 4 under the force of the pump 7, thus avoiding blockage of the drain pipe 4.

[0018] like Figures 1 to 3As shown, a filter screen is installed in the drain pipe 4. An inspection port 10 is provided on the side wall of the drain pipe 4 for the filter screen to pass through. A sealing cap 11 is detachably connected to the inspection port 10 via fastening bolts. The mesh size of the filter screen is selected according to the viscosity of the dye used in the dyeing tank 1. The filter screen reduces the possibility of fabric debris and other particles mixed in the dye entering the return chamber 5, and reduces the possibility of the outlet 6 being blocked by fabric debris and other impurities. After the filter screen has been used for a period of time, the operator needs to remove the fastening bolts and open the sealing cap 11 to remove the filter screen from the inspection port 10. Then, the impurities blocked on the filter screen should be cleaned to prevent excessive impurities from adhering to the filter screen and affecting its performance. The flow of the filter screen is affected. The filter screen includes a reinforcing frame 8 and a mesh 9. The mesh 9 is detachably connected to the reinforcing frame 8 by fixing screws 15. Since the dye flows unidirectionally in the drain pipe 4, the pressure of the dye on the mesh 9 is always directed towards the rotating shaft 2. Placing the reinforcing frame 8 on the side of the filter screen facing away from the rotating shaft 2 ensures the support effect of the reinforcing frame 8 on the mesh 9. During the use of the filter screen, when the mesh 9 or the reinforcing frame 8 is damaged, the staff can separate the reinforcing frame 8 from the mesh 9 by removing the fixing screws 15, and then replace the damaged mesh 9 or the reinforcing frame 8. The intact reinforcing frame 8 or mesh 9 can still be used, reducing resource waste and facilitating maintenance. The access port 10 is located near the connection between the drain pipe 4 and the rotating shaft 2. This arrangement places the access port 10 close to the axis of the dyeing tank 1. When the pump 7 stops working, the dye in the drain pipe 4 will flow back into the drain chamber 102 under gravity, reducing dye residue near the access port 10 when the filter is being maintained, thus reducing dye waste. The separator includes a mesh body 13 and a support 14. The support 14 is equipped with a sealed bearing 12 that is rotatably connected to the outer peripheral wall of the rotating shaft 2. The mesh body 13 effectively blocks the fabric, preventing it from entering the drain chamber 102. The support 14 provides good support for the mesh body 13 and also supports the rotating shaft 2. To prevent axial runout of the rotating shaft 2 during rotation and ensure the stability of the dyeing and printing equipment, a sealed bearing 12 is used to rotately connect with the rotating shaft 2, making it difficult for dye to enter the sealed bearing 12 and reducing the possibility of dye corrosion of the sealed bearing 12. The opening area of ​​the outlet 6 on the stirring rod 3 is smaller than the opening area at the connection between the outlet 6 and the return chamber 5. Since the amount of dye flowing through the outlet 6 per unit time is fixed, when the same volume of dye needs to pass through a smaller opening, the flow rate of the dye will increase, thereby increasing the fluid pressure of the dye when it leaves the outlet 6. This ensures the effect of the dye being expelled from the outlet 6 on the fabric and reduces the working load of the pump 7.
