Description

Technical Field

[0001] This utility model relates to the field of sizing machine technology, and in particular to a high-efficiency sizing mixer for spunlace nonwoven fabric processing. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, or needle-punched non-woven fabric, is made from polyester fibers and manufactured through a needle-punching process, allowing for different thicknesses, textures, and hardnesses. Non-woven fabric is characterized by its moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic, odorless, inexpensive, and recyclable properties. It can be used in various industries, such as sound insulation, heat insulation, heating elements, masks, clothing, medical applications, and as filling materials. During the manufacturing process, non-woven fabric requires a sizing machine for sizing.

[0003] The existing technology has the following problems:

[0004] 1. Existing sizing machines often have wood pulp that easily solidifies during use, requiring manual stirring by workers, which is time-consuming and labor-intensive, reducing the practicality of the sizing machine.

[0005] 2. Existing sizing machines do not apply sizing evenly to nonwoven fabrics, resulting in an uneven surface and increasing the defect rate of nonwoven fabrics, thus reducing the working efficiency of the sizing machine. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-efficiency sizing mixer for spunlace nonwoven fabric processing. This high-efficiency sizing mixer can automatically homogenize the sizing, thereby improving the practicality and working efficiency of the sizing machine.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A high-efficiency slurry mixer for spunlace nonwoven fabric processing includes: a slurry pump, a high-efficiency slurry mixer mounted on the slurry pump, and a sizing machine mounted on the high-efficiency slurry mixer.

[0009] Preferably, the high-efficiency slurry mixer includes a mixing cylinder, a slurry outlet on one side of the mixing cylinder, a slurry inlet used in conjunction with the slurry outlet, and several pairs of homogenizers disposed between the slurry inlet and the slurry outlet.

[0010] Preferably, the homogenizer includes a disc installed inside a mixing cylinder, a sealing plate disposed on the disc, a cylinder installed on the sealing plate and the disc, and a plurality of pairs of homogenizing ports opened on the cylinder; the plurality of pairs of homogenizing ports are distributed in an array along the axis of the cylinder.

[0011] Preferably, the sum of the areas of the plurality of pairs of homogenizing inlets is equal to the cross-sectional area of ​​the inlet.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] This invention uses a high-efficiency pulp mixer to replace manual stirring, solving the problem of time-consuming and labor-intensive manual stirring and improving the practicality of the sizing machine. Specifically, the high-efficiency pulp mixer is equipped with a homogenizer, which has homogenizing ports. Pulp enters from several pairs of homogenizing ports, and the pulp entering from different ports flushes against each other. Under the action of the flushing force, the wood pulp in the pulp is dispersed and evenly dissolved into the water, improving the working efficiency of the sizing machine and reducing the defect rate of nonwoven fabric.

[0021] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other. Example

[0022] A high-efficiency slurry mixer for spunlace nonwoven fabric processing includes: a slurry pump 10, a high-efficiency slurry mixer 20 mounted on the slurry pump 10, and a sizing machine 30 mounted on the high-efficiency slurry mixer 20.

[0023] like Figure 1 As shown, in the existing technology of sizing spunlace nonwoven fabric, the sizing is generally carried out directly by the sizing machine 30 after the sizing pump 10 discharges the sizing. In order to prevent the sizing from solidifying, it is necessary to manually stir it before the sizing pump 10 discharges the sizing. Such operation is time-consuming and labor-intensive.

[0024] This invention installs a high-efficiency slurry mixer 20 between the slurry pump 10 and the slurry machine 30. The high-efficiency slurry mixer 20 uses water pressure to flush the wood pulp in the slurry sprayed by the slurry pump 10, dispersing the wood pulp and dissolving it evenly in the water, thereby improving the practicality and working efficiency of the slurry machine 30.

[0025] like Figure 2 As shown, the high-efficiency slurry mixer 20 includes a mixing cylinder 21, a slurry outlet 22 opened on one side of the mixing cylinder 21, a slurry inlet 23 used in conjunction with the slurry outlet 22, and a plurality of pairs of homogenizers 24 disposed between the slurry inlet 23 and the slurry outlet 22.

[0026] The mixing cylinder 21 has a slurry outlet 22 at one end and a slurry inlet 23 at the other end. The slurry inlet 23 is connected to the slurry pump 10; the slurry outlet 22 is connected to the slurry feeding machine 30.

[0027] After being pumped out by the slurry pump 10, the slurry enters the mixing cylinder 21 through the slurry inlet 23 and is homogenized by the homogenizer 24 in the mixing cylinder 21. After homogenization, it enters the sizing machine 30 through the slurry outlet 22 to sizing the nonwoven fabric.

[0028] like Figure 3 As shown, the homogenizer 24 includes a disc 241 installed inside the mixing cylinder 21, a sealing plate 242 disposed on the disc 241, a cylinder 243 installed on the sealing plate 242 and the disc 241, and a plurality of homogenizing ports 244 opened on the cylinder 243; the plurality of homogenizing ports 244 are distributed in an array along the axis of the cylinder 243.

[0029] Furthermore, the sum of the areas of the plurality of pairs of homogenizing ports 244 is equal to the cross-sectional area of ​​the slurry inlet 23.

[0030] When the total area of ​​the several pairs of uniform mixing ports 244 is less than the cross-sectional area of ​​the pulp inlet 23, pulp will not be able to effectively enter the uniform mixing ports 244 after entering the pulp inlet 23, resulting in pulp backflow. Conversely, when the total area of ​​the several pairs of uniform mixing ports 244 is greater than the cross-sectional area of ​​the pulp inlet 23, the pulp will not receive sufficient flushing pressure after entering the pulp inlet 23, thus preventing the wood pulp from being effectively dispersed. Therefore, the total area of ​​the several pairs of uniform mixing ports 244 should be equal to the cross-sectional area of ​​the pulp inlet 23. This arrangement can effectively solve the above two problems.

[0031] The number of uniform mixing ports 244 is equal to the cross-sectional area of ​​the pulp inlet 23 divided by the opening area of ​​the uniform mixing ports 244, but at least a pair is provided. When the pulp enters from these two symmetrical uniform mixing ports 244 respectively, a flushing effect will be formed, thereby dispersing the wood pulp in the pulp and dissolving it evenly into the water.

[0032] The number of homogenizers 24 can be set according to the actual needs on site. In this embodiment, five homogenizers are provided. The pulp water enters the homogenizers 24 multiple times for flushing, which can completely disperse the wood pulp in the pulp water and evenly dissolve it in the water. Then, it is sprayed out from the pulp outlet 22 into the sizing machine 30 to sizing the non-woven fabric, which can effectively improve the practicality and working efficiency of the sizing machine 30.

[0033] like Figures 1 to 3As shown, the working principle of this utility model is as follows: Slurry is sprayed out from the slurry pump 10 and enters the mixing cylinder 21 through the slurry inlet 23. Then, it enters the next slurry homogenizer 24 through several pairs of homogenizing ports 244 on the homogenizer 24 of the mixing cylinder 21. When passing through several pairs of homogenizing ports 244, the slurry is sprayed out from the symmetrical homogenizing ports 244, forming a counter-current effect, which counter-currently disperses the wood pulp in the slurry and dissolves it evenly in the water. After passing through multiple homogenizers 24, the wood pulp has been completely and evenly dissolved in the water. Then, it enters the sizing machine 30 from the slurry outlet 22 to sizing the nonwoven fabric. This process effectively improves the practicality and working efficiency of the sizing machine 30.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
