A dyeing device

Abstract

This utility model discloses a dyeing device, relating to the field of printing and dyeing machinery technology. The key technical points are: it includes a dyeing kettle body, a stirring mechanism in the middle of the dyeing kettle body, a drive motor at one end of the dyeing kettle body, and a drive motor providing torque to the stirring mechanism via a transmission shaft. The stirring mechanism has barrier meshes on both sides and includes paddles. The inclined paddles ensure the fluidity of the dye liquor during operation, allowing the stirred dye liquor to flow within the dyeing kettle body, enabling more thorough contact with the fabric and improving the uniformity of dyeing. During operation, the fabric is blocked by the barrier meshes, preventing direct contact between the stirring mechanism and the fabric. This avoids the possibility of the fabric being damaged due to friction caused by the stirring mechanism rubbing against the inner wall of the dyeing kettle body. Furthermore, because the dye liquor can pass through the barrier meshes effectively, the barrier meshes do not significantly affect the fluidity of the dye liquor.

Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing machinery technology, and more specifically, it relates to a dyeing device. Background Technology

[0002] Fabric is a common material in people's daily lives. The production process of fabric involves dyeing, which requires the use of dyeing equipment.

[0003] Chinese Patent No. CN222313548U discloses a high-efficiency fabric dyeing device. Its key technical features are: a dyeing vessel body, which is arranged horizontally and has a feeding component at the top, a stirring component inside the dyeing vessel body, and a jacket at the bottom of the dyeing vessel body. The jacket is hollow and has an inlet pipe and an outlet pipe on one side.

[0004] The above solution shortens the dyeing and fixing time of the fabric and improves dyeing efficiency by heating the dye liquor evenly and ensuring a suitable dyeing temperature. However, since the fabric undergoes desizing treatment before dyeing, the fabric structure becomes loose. At the same time, the stirring component also rolls up the fabric while stirring the dye liquor, causing the fabric to rub against the inner wall of the dyeing kettle, which may cause the fabric to break.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dyeing device.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dyeing device, including a horizontally placed dyeing kettle body, a stirring mechanism provided in the middle of the dyeing kettle body, a drive motor provided at one end of the dyeing kettle body, the drive motor providing torque to the stirring mechanism through a transmission shaft, a blocking mesh for blocking the fabric provided on both sides of the stirring mechanism, and a plurality of inclined blades provided on the stirring mechanism.

[0008] The present invention is further configured such that: the stirring mechanism includes a disc fixed on the outer peripheral wall of the transmission shaft, the paddles are arranged in annular array on the outer peripheral wall of the disc, and the disc is hollow.

[0009] The present invention is further configured such that: the barrier mesh is provided with a circular opening for the transmission shaft to pass through, and a reinforcing ring is provided in the circular opening, the inner diameter of the reinforcing ring being larger than the outer diameter of the transmission shaft.

[0010] The present invention is further configured such that a horizontally arranged support rod is fixed on the barrier mesh.

[0011] The present invention is further configured such that the support rod is disposed between the barrier mesh and the stirring mechanism.

[0012] The present invention is further configured such that the stirring mechanism is made of stainless steel.

[0013] In summary, this utility model has the following beneficial effects: When using the dyeing device, open the lid and place the dye liquor and fabric into the dyeing kettle through the feed pipe. Then close the lid and start the drive motor. The drive motor drives the stirring mechanism through the transmission shaft. The inclined blades on the stirring mechanism can better ensure the flow of the dye liquor in the dyeing kettle, allowing the stirring mechanism to stir the dye liquor and reduce the occurrence of dye liquor sedimentation. At the same time, the stirred dye liquor will flow in the dyeing kettle, allowing the dye liquor to come into more full contact with the fabric and improve the uniformity of the dyeing process. When the stirring mechanism is running, the fabric will be blocked by the barrier mesh, preventing the stirring mechanism from directly contacting the fabric. This avoids the possibility of the fabric being damaged due to friction between the stirring mechanism and the inner wall of the dyeing kettle. Since the dye liquor can pass through the barrier mesh well, the barrier mesh is not likely to affect the flow of the dye liquor. Attached Figure Description

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

[0017] A staining apparatus, such as Figure 1As shown, the apparatus includes a horizontally placed dyeing vessel 1. The top of the dyeing vessel 1 is equipped with a feed pipe and a hinged cover. A jacket for heating the dyeing vessel 1 is tightly attached to the outside of the dyeing vessel 1, and the jacket is filled with heat-conducting oil. A delivery pipe for the heat-conducting oil is located on one side of the jacket. A stirring mechanism is located in the middle of the dyeing vessel 1, and a drive motor 2 is located at one end of the dyeing vessel 1. The drive motor 2 provides torque to the stirring mechanism via a transmission shaft 3. Barrier mesh 4 for blocking the fabric is located on both sides of the stirring mechanism. The stirring mechanism includes several inclined blades 5. When using the dyeing apparatus, the hinged cover is opened, and the dye liquor and fabric are placed into the dyeing vessel 1 through the feed pipe. Then, the hinged cover is closed, and the drive motor 2 is started, causing the drive motor 2 to... The drive shaft 3 drives the stirring mechanism to work. The inclined blades 5 on the stirring mechanism can better ensure the flowability of the dye liquor in the dyeing kettle 1, so that the stirring mechanism can stir the dye liquor and reduce the occurrence of dye liquor sedimentation. At the same time, the stirred dye liquor will flow in the dyeing kettle 1, so that the dye liquor can come into more full contact with the fabric and improve the uniformity of fabric printing and dyeing. When the stirring mechanism is running, the fabric will be blocked by the blocking mesh 4, so that the stirring mechanism cannot come into direct contact with the fabric. This can avoid the possibility of the fabric being damaged by friction between the stirring mechanism and the inner wall of the dyeing kettle 1. Since the dye liquor can pass through the blocking mesh 4 well, the setting of the blocking mesh 4 is not likely to affect the flowability of the dye liquor.

[0018] like Figure 1 and Figure 2As shown, the stirring mechanism includes a disc 6 fixed to the outer peripheral wall of the drive shaft 3, and paddles 5 arranged in a ring array on the outer peripheral wall of the disc 6. The disc 6 is hollow, which significantly reduces its mass, lowers the load on the drive motor 2, reduces vibration during rotation, and ensures the stability of the stirring mechanism. The barrier mesh 4 has a circular opening for the drive shaft 3 to pass through, and a reinforcing ring 7 is provided in the opening. The reinforcing ring 7 improves the strength of the barrier mesh 4 near the opening. Furthermore, the inner diameter of the reinforcing ring 7 is larger than the outer diameter of the drive shaft 3, preventing relative friction between the drive shaft 3 and the reinforcing ring 7, thus reducing the impact of the drive shaft 3's operation on the stability of the barrier mesh 4. A horizontally arranged support rod 8 is fixed to the barrier mesh 4, which improves the overall strength of the barrier mesh 4 and ensures its effective blocking of the fabric. The support rod 8 is positioned near the lower part of the drive shaft 3. Since the dye liquor accumulates at the bottom of the dyeing vessel 1 under gravity, the impact of the dye liquor on the barrier mesh 4 is mainly concentrated below the barrier mesh 4 during the operation of the stirring mechanism. Positioning the support rod 8 near the lower part of the drive shaft 3 increases the strength of the lower half of the barrier mesh 4 and reduces the possibility of deformation under the impact of the dye liquor. The support rod 8 is positioned between the barrier mesh 4 and the stirring mechanism, preventing the fabric from directly contacting the support rod 8 and avoiding damage to the fabric when they come into contact. This ensures the integrity of the fabric in the dyeing vessel 1. The stirring mechanism is made of stainless steel, which has excellent chemical corrosion resistance. Using this material, the stirring mechanism can better adapt to working environments with prolonged contact with dye liquor, thus extending its service life.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
