Description

Technical Field

[0001] The invention belongs to the technical field of waterproof spraying, and in particular relates to a high-density waterproof layer spraying device on the surface of a silk fabric. Background Art

[0002] Silk fabrics are widely used in high-end clothing, home textiles and other fields due to their excellent properties such as softness, smoothness and breathability. However, there are some problems in the processing and use of silk fabrics, especially in surface treatment, such as spraying waterproof layer and other processes, which face many challenges.

[0003] Traditional fabric spraying equipment usually uses a linear or simple conveying path to transport fabrics. When processing silk fabrics, this method is prone to accumulate internal stress in the fabric during processing due to the material characteristics of silk itself. Silk fabric fibers are relatively thin and have relatively low strength. During the linear conveying process, the tension on the fabric is unevenly distributed. Especially in processing procedures such as spraying, the spraying process of the waterproofing agent will be significantly disturbed due to the existence of internal stress in the silk fabric. Stress causes the arrangement and tension state of the fabric fibers to change, making it difficult for the waterproofing agent to adhere evenly to the fabric surface during spraying, resulting in uneven spraying. At the same time, stress can cause local deformation of the fabric, forming defects such as wrinkles, which will further affect the uniformity of the distribution and density consistency of the waterproof layer on the fabric surface, thereby reducing the overall quality and performance of the waterproof layer.

[0004] In order to avoid the above technical problems, it is necessary to provide a high-density waterproof layer spraying device for the surface of silk fabric to overcome the above defects in the prior art. Summary of the invention

A liquid storage tank for storing waterproofing agent is installed on the spray box. One side of the two spray nozzles is connected to the liquid storage tank through a delivery hard pipe. A delivery pump for providing delivery power is arranged on the two delivery hard pipes. The delivery pump draws out the waterproofing agent in the liquid storage tank through power and delivers it to the spray nozzle through the delivery hard pipe to spray the surface of the silk fabric conveyed through it. The two spray nozzles are respectively located obliquely above and obliquely below the inclined surface of one side of the V-shaped conveying path on the middle roller and the two inner rollers.

[0007] As a preferred embodiment, the spray box is provided with an arc-shaped processing liquid frame for storing the waterproofing agent sprayed and containing a certain amount of waterproofing agent. The intermediate roller is located as a whole in the arc-shaped processing liquid frame, and the silk fabric transported by the intermediate roller will be soaked and contacted with the waterproofing agent in the arc-shaped processing liquid frame again.

[0008] As a preferred embodiment, a heating rod capable of heating the waterproofing agent therein is provided in the arc-shaped machining fluid frame, and the heating temperature range of the waterproofing agent by the heating rod is 40°C to 80°C. Liquid outlet side holes for controlling the liquid level of the waterproofing agent are provided on both sides of the arc-shaped machining fluid frame.

[0009] As a preferred embodiment, two roller brushes are rotatably arranged in the spray box and are located in an arc-shaped processing liquid frame and are used to evenly wipe the fabric passing under the middle roller.

[0010] As a preferred embodiment, the two roller brushes are respectively provided with gears at the rotation positions on the front side of the spray box, the two gears are meshed with each other, and one of the gears is connected to the motor drive fixed on the front side of the spray box.

[0011] As a preferred embodiment, the interiors of the two roller brushes are hollow, and the surfaces of the two roller brushes are provided with a plurality of side grooves.

[0012] As a preferred embodiment, the two roller brushes can stir the waterproofing agent in the arc-shaped machining fluid frame through the non-smooth surface features of the side grooves when rotating.

[0013] As a preferred embodiment, the interior of the intermediate roller is hollow, and a plurality of elastic expansion grooves are provided on the surface of the intermediate roller. A fixing rod is fixedly connected to the interior of the intermediate roller, and a plurality of elastic pressure blocks are fixedly provided on the exterior of the fixing rod via a plurality of elastic expansion rods.

[0014] As a preferred implementation scheme, the elastic pressure block cooperates with two roller brushes to elastically press the warp conveying fabric, and the surfaces of the plurality of elastic pressure blocks slide in the corresponding elastic expansion grooves.

[0015] As a preferred embodiment, the elastic telescopic rod includes a telescopic tube and a telescopic column, the telescopic column slides and telescopes on the telescopic tube, a spring is arranged inside the telescopic tube, a sliding limit block is fixedly arranged at the bottom end of the telescopic column, the sliding limit block is slidably arranged in the telescopic tube, and the sliding limit block is located at the top end of the spring, when the elastic telescopic rod is extended or retracted, the telescopic column squeezes the spring in the telescopic tube through the sliding limit block to achieve adaptive extension and retraction.

[0016] Compared with the prior art, the present invention has the following beneficial effects: According to the present invention, when the silk fabric passes through the V-shaped path formed between the inner roller and the middle roller in the spray box, a certain bending angle is generated, which effectively releases the stress accumulated inside the fabric. In this process, the oblique conveying is coordinated with the spray nozzles obliquely above and below to eliminate the disadvantage of single-sided spraying, ensure the uniform distribution of the spray liquid, and the fabric fibers are stretched and the fabric gaps are improved during the first pass, thereby improving the spray density and the quality of the waterproof layer. After the fabric is sprayed, it will continue along the other side of the V-shaped inclined surface, that is, when it passes between the inner roller and the middle roller again, secondary stress release will occur, which will enable the waterproof agent to better penetrate into the fiber gaps, enhance the durability and wear resistance of the waterproof layer, and effectively solve the stress and uneven spraying problems caused by traditional linear conveying.

[0017] The invention allows the oblique conveyance of fabrics to naturally accumulate the spray liquid in the arc-shaped processing liquid frame, and the heating rod controls the temperature of the waterproofing agent in the arc-shaped processing liquid frame at 40° C. to 80° C. to soften the fiber and enhance the activity. After the fabrics are in contact, the roller brush driven by the motor rotates in the reverse direction to wipe, and the roller brush turns over the waterproofing agent to achieve full wetting and uniform spraying, thereby improving the spraying quality of the silk fabrics.

[0018] In the present invention, the fabric conveying clock drives the middle roller to rotate, and the elastic pressure block adaptively presses under the action of the elastic telescopic rod to generate a dynamic force to further dissipate the stress and optimize the gap between fabric fibers. Compared with simple roller surface contact, it is more comprehensive and effective. In combination with the roller brush, the stress is adjusted from multiple aspects, so that the stress of the fabric is maintained in optimization during processing, thereby improving the combination effect of the waterproof layer and the fabric and the product performance.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] The following examples are used to illustrate the present invention, but they cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0024] See also Figure 1-10 The present invention provides a high-density waterproof layer spraying device for the surface of a silk fabric, comprising a spray box 1, both sides of the spray box 1 are provided with a conveying roller group 2 for conveying the silk fabric, the inside of the spray box 1 is respectively provided with two inner rollers 3 and a middle roller 4 for rotating, the middle roller 4 is located below the two inner rollers 3, and the fabric conveying path formed by the middle roller 4 and the two inner rollers 3 is V-shaped, and the fabric passing between the middle roller 4 and the two inner rollers 3 will change its conveying path; Two spray nozzles 5 for spraying a waterproof layer on the surface of silk fabrics are arranged inside the spray box 1. A liquid storage tank 6 for storing waterproofing agent is installed on the spray box 1. One side of the two spray nozzles 5 is connected to the liquid storage tank 6 through a delivery hard pipe 7. A delivery pump 8 for providing delivery power is arranged on the two delivery hard pipes 7. The delivery pump 8 extracts the waterproofing agent in the liquid storage tank 6 by power and delivers it to the spray nozzle 5 through the delivery hard pipe 7 to spray the surface of the silk fabric conveyed through the delivery. The two spray nozzles 5 are respectively located obliquely above and obliquely below the inclined surface of one side of the V-shaped conveying path on the middle roller 4 and the two inner rollers 3. When the silk fabric passes through the V-shaped path formed between the inner roller 3 and the middle roller 4 in the spray box 1, a certain bending angle is generated. Based on the stress relaxation principle of the material, the stress accumulated inside the fabric is effectively released. In this process, the two spray nozzles 5 are respectively located obliquely above and obliquely below, and their spraying angles are cleverly coordinated with the movement direction of the fabric, eliminating the blind spots and uneven thickness that are prone to occur in single-sided spraying. The problem is that the oblique conveying path also plays a good guiding role for the spray liquid. During the oblique conveying process, the spray liquid is guided by the path, avoiding the free flow caused by gravity, and ensuring the uniform distribution of the spray liquid on the fabric. At the same time, when the fabric passes between the inner roller 3 and the middle roller 4 for the first time to release the stress, the fabric fibers are stretched, and the uneven fiber gap phenomenon that may be caused by stress concentration is improved, which enables the waterproofing agent sprayed by the spray nozzle 5 to fill the fiber gap more evenly, thereby achieving a more uniform and sufficient spraying density, greatly improving the overall quality and waterproof performance of the waterproof layer. In addition, after the fabric is sprayed for the first time, it continues along the other side of the V-shape, that is, when it passes between the inner roller 3 and the middle roller 4 again, a secondary stress release will occur, and the fabric fibers will undergo microscopic adjustments, which will enable the waterproofing agent to better penetrate into the fiber gaps, and form a tighter and firmer waterproof layer structure after curing, which significantly improves the durability and wear resistance of the waterproof layer.

[0025] like Figure 4 As shown, the spray box 1 is provided with an arc-shaped processing liquid frame 9 for storing the waterproofing agent sprayed and containing a certain amount of waterproofing agent. The intermediate roller 4 is located in the arc-shaped processing liquid frame 9 as a whole, and the silk fabric conveyed by the intermediate roller 4 will be soaked and contacted with the waterproofing agent in the arc-shaped processing liquid frame 9 again.

[0026] like Figure 4 As shown, a heating rod 10 capable of heating the waterproofing agent therein is provided in the arc-shaped machining liquid frame 9, and the heating temperature range of the waterproofing agent by the heating rod 10 is 40°C to 80°C. Liquid outlet side holes 19 capable of controlling the liquid level of the waterproofing agent are provided on both sides of the arc-shaped machining liquid frame 9.

[0027] like Figure 4 As shown, two roller brushes 11 are rotatably arranged in the spray box 1 and are located in an arc-shaped processing liquid frame 9 and are used to evenly wipe the fabric passing under the middle roller 4.

[0028] like Figure 1 and Figure 4 As shown, two roller brushes 11 are respectively provided with gears 12 at the rotating parts on the front side of the spray box 1, and the two gears 12 are meshed with each other, and one of the gears 12 is connected to the motor 13 fixed on the front side of the spray box 1. Due to the good diversion effect of the oblique conveying path on the spray liquid, the spray liquid is naturally accumulated in the arc-shaped processing liquid frame 9, and the heating rod 10 just controls the temperature of the waterproofing agent at 40°C to 80°C. This temperature range can not only effectively soften the silk fiber and reduce the internal stress, but also enhance the activity of the waterproofing agent and make it easier to combine with the fabric. When the fabric passes through the middle roller 4 and shallowly contacts the waterproofing agent in the arc-shaped processing liquid frame 9, it enters the fine processing stage dominated by the two roller brushes 11. The motor 13 drives the two roller brushes 11 to rotate in opposite directions through the mutually meshing gears 12, and wipes the soaked fabric evenly in all directions. This mechanical friction not only helps to further release the stress inside the fabric, but also promotes the waterproofing agent to be evenly distributed on the surface of the fabric. During the rotation process, the roller brush 11 fully turns and stirs the waterproofing agent in the arc-shaped processing liquid frame 9, which makes the waterproofing agent constantly contact with the fabric, so that in addition to waterproof spraying, a fully uniform soaking effect can also be achieved. In summary, the waterproofing agent can penetrate more fully, thereby improving the quality of the silk fabric spraying.

[0029] like Figure 5 As shown, the interiors of the two roller brushes 11 are hollow, and a plurality of side grooves 14 are formed on the surfaces of the two roller brushes 11 .

[0030] like Figure 4 and Figure 5 As shown, the two roller brushes 11 can stir the waterproofing agent in the arc-shaped machining fluid frame 9 through the non-smooth surface features of the side grooves 14 when rotating.

[0031] like Figure 7 and Figure 8 As shown, the interior of the intermediate roller 4 is hollow, and a plurality of elastic expansion and contraction grooves 15 are provided on the surface of the intermediate roller 4. A fixing rod 16 is fixedly connected to the interior of the intermediate roller 4, and a plurality of elastic pressure blocks 18 are fixedly provided on the exterior of the fixing rod 16 via a plurality of elastic expansion and contraction rods 17.

[0032] like Figure 8 and Fig. 9As shown, the elastic pressure block 18 cooperates with the two roller brushes 11 to elastically press the warp conveying fabric, and the surfaces of the multiple elastic pressure blocks 18 slide in the corresponding elastic expansion grooves 15. When the fabric is conveyed in the equipment and passes through the middle roller 4, it will drive the middle roller 4 to rotate. At this time, the elastic pressure block 18 located at the bottom and in contact with the fabric, under the action of the elastic expansion rod 17, performs adaptive elastic pressure according to the actual situation of the fabric. Under the action of the elastic pressure block 18, the fabric fibers are subjected to periodic and direction-changing extrusion and friction forces, so that the stress originally accumulated during the processing is gradually dissipated under this dynamic force. Compared with simple roller surface contact, this elastic pressure method can act more comprehensively on various parts of the fabric to ensure the uniformity of stress release. The gaps between the fabric fibers are continuously adjusted and optimized, becoming more uniform and small, so that the waterproofing agent is more closely and evenly attached to the fabric. In combination with the elastic pressure of the two roller brushes 11 on the warp conveying fabric, the stress of the fabric is adjusted from multiple angles. The synergistic effect of the roller brush 11 and the elastic pressure block 18 , so that the fabric is always in a stress-optimized state during the soaking and spraying process, which not only helps to improve the stability of the fabric in the subsequent processing process, but also ensures that the waterproof layer and the fabric are more closely and evenly bonded, greatly improving the spraying quality of the high-density waterproof layer on the surface of the silk fabric and the overall performance of the product. In addition, the middle roller 4, with its internal elastic telescopic rod 17 and external elastic pressure block 18, realizes adaptive elastic pressure rotation when the fabric drives it to rotate. When the fabric passes through the middle roller 4 along the V-shaped conveying path, this rotation mode of the elastic pressure block 18 can effectively turn over the waterproofing agent accumulated on the V-shaped conveying path, and produce dynamic contact with the waterproofing agent, so that the waterproofing agent is no longer in a relatively static state, but forms local flow and tumbling. At the same time, the side groove 14 on the surface of the roller brush 11 is used to strongly stir the waterproofing agent in the arc-shaped processing liquid frame 9, further enhancing the fluidity and activity of the waterproofing agent. This synergistic effect first ensures that the distribution of the waterproofing agent around the fabric is more uniform, and effectively improves the overall uniformity and consistency of the waterproof layer.

[0033] like Fig.10 As shown, the elastic telescopic rod 17 includes a telescopic tube 171 and a telescopic column 172. The telescopic column 172 is slidably telescopic on the telescopic tube 171. A spring 173 is arranged inside the telescopic tube 171. A sliding limit block 174 is fixedly arranged at the bottom end of the telescopic column 172. The sliding limit block 174 is slidably arranged in the telescopic tube 171, and the sliding limit block 174 is located at the top of the spring 173. When the elastic telescopic rod 17 is extended or retracted, the telescopic column 172 squeezes the spring 173 in the telescopic tube 171 through the sliding limit block 174 to achieve adaptive extension and retraction.

[0034] The working principle and use process of the present invention are as follows: first, the equipment is turned on, and the conveying roller group 2 drives the fabric to enter the spray box 1 at a uniform speed. After the fabric enters the spray box 1, it is conveyed along the V-shaped path formed by the two inner rollers 3 and the middle roller 4, so that the fabric can achieve preliminary stress release. In this process, the elastic pressure block 18 of the middle roller 4, under the action of the elastic telescopic rod 17, performs adaptive elastic pressure on the fabric according to the actual situation of the fabric. When the fabric passes through the middle roller 4, it drives the middle roller 4 to rotate. The contact between the elastic pressure block 18 and the fabric not only helps to release the internal stress of the fabric, but also can turn over the waterproofing agent accumulated on the V-shaped conveying path; at the same time, the waterproofing agent in the liquid storage tank 6 is conveyed to the spray nozzle 5 through the conveying hard pipe 7 under the action of the conveying pump 8, and the two spray nozzles 5 are respectively from the V The upper and lower sides of the inclined surface on one side of the arc-shaped path are used to spray the fabric being transported; in the arc-shaped processing liquid frame 9, the heating rod 10 heats the waterproofing agent to a suitable temperature of 40 to 80 degrees, which helps to soften the silk fabric, reduce internal stress, and enhance the activity of the waterproofing agent. When the fabric passes through the middle roller 4, it will have a shallow contact with the waterproofing agent in the arc-shaped processing liquid frame 9, so that the fabric is initially soaked; the motor 13 drives one of the gears 12 to rotate, and the two roller brushes 11 are driven to rotate in the opposite direction at high speed in the arc-shaped processing liquid frame 9 through the mutually meshing gears 12. The side grooves 14 on the surface of the roller brush 11 stir the waterproofing agent to further enhance the flow of the waterproofing agent. The properties and activity of the waterproof agent make the fabric more fully infiltrated. During the rotation of the roller brush 11, it evenly wipes the fabric passing under the middle roller 4, and cooperates with the elastic pressure of the elastic pressure block 18 on the fabric to further release the stress of the fabric, while ensuring that the waterproof agent is evenly distributed on the surface of the fabric, thereby improving the uniformity and adhesion of the waterproof layer; during the entire spraying process, the arc-shaped processing liquid frame 9 can discharge liquid accordingly through the liquid outlet side holes 19 on both sides, so as to control the waterproof agent position to achieve the best processing effect. When the fabric completes the processing flow in the spray box 1, it is sent out by the conveying roller group 2 on the other side to complete the spraying operation of the high-density waterproof layer on the surface of the silk fabric.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
