Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a spray device for testing the waterproofness of textiles. Background Technology

[0002] Functional textiles now hold a significant position in the textile market, and waterproofing is a crucial characteristic of them. Water resistance refers to a fabric's ability to resist wetting and penetration by water, primarily assessed through hydrostatic pressure rating and water repellency rating. The water repellency rating can be tested using a spray method to evaluate the fabric's water-repellent properties and its waterproofing effectiveness.

[0003] The specific testing procedure is as follows: the sample is installed on the entire ring clamp, the clamp is fixed on a plane at a 45° angle, 250ml of water is added to a funnel at a certain distance from the plane, the water flows to the fabric through the spray head of the funnel, and the spray lasts for about 25-30 seconds. After the test, the water staining phenomenon on the fabric surface is observed to evaluate its water staining level and thus evaluate the waterproof performance of the fabric.

[0004] In the current spray testing equipment, the spray water is manually poured in by the operator and flows directly out through the spray head connected to the funnel. During the test, it is difficult for the operator to control the water to be poured into the funnel at the same height and at the same rate. Water splashes and foam are also generated during the water addition process. The water pressure on the spray head is not fixed in the initial, middle and late stages of the feeding process, and it is greatly affected by the operator's human factors. This will affect the testing process and evaluation results. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a spray device for testing the waterproofness of textiles that is highly stable and has a compact structure.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A spray device for testing the waterproofness of textiles includes a frame, characterized in that it further includes a drive component, a guide rail, a slider, and a spray assembly. The guide rail is vertically mounted on the frame, and the spray assembly is connected to the guide rail. The drive component is fixed to the frame and connected to the spray assembly. A height marking component is provided between the spray assembly and the frame. The drive component can drive the spray assembly to move up and down along the guide rail.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 and Figure 2 As shown, the spray device for testing the waterproofness of textiles includes a frame 1, a drive unit, a guide rail 3, a slider 4, and a spray assembly. The guide rail 3 is vertically mounted on the frame 1, and the spray assembly is connected to the guide rail 3. The drive unit is fixed to the frame 1 and connected to the spray assembly. A height indicator component is provided between the spray assembly and the frame 1. The drive unit can drive the spray assembly to move up and down along the guide rail 3. After the spray assembly moves, the height position of the spray assembly can be visually viewed through the height indicator component.

[0027] During the waterproof testing of textiles, the textile to be tested is positioned vertically to ensure that it is stably unfolded.

[0028] The technical problem this patent application aims to solve is how to stably spray water mist onto textiles. However, how the textiles are vertically positioned is not a technical problem addressed in this patent application. Therefore, this embodiment will not elaborate on that part of the technical features.

[0029] After the driving component moves the slider 4 along the guide rail 3, it can position the slider 4 at a set height. Since the spray assembly is connected to the slider 4, it can ultimately be positioned at the set height.

[0030] It can be seen that after the spraying component moves up and down, it can spray evenly on all parts of the tested textile.

[0031] Meanwhile, the height marking component can intuitively inform testers of the height and position of the spray component.

[0032] The driving component includes a motor 2, a lead screw 5, a driving wheel 6, and a driven wheel 7. The motor 2 is fixedly connected to the frame 1. The lead screw 5 is axially fixed to the frame 1 and can rotate circumferentially. The driven wheel 7 is fixedly connected to the upper end of the lead screw 5. The driving wheel 6 is connected to the driving component. It also includes a transmission belt 8, which is sleeved on the driving wheel 6 and the driven wheel 7. The slider 4 has a cylindrical connecting cylinder 4a1, which is sleeved on the lead screw 5 and the two are threadedly connected.

[0033] During the continuous rotation of motor 2, the lead screw 5 can be continuously rotated by the action of the driving wheel 6, the driven wheel 7 and the transmission belt 8. Since the lead screw 5 is threadedly connected to the slider 4, the slider 4, which does not rotate with it, will move up and down along the axial direction of the lead screw 5.

[0034] The motor 2 is located on the side of the lead screw 5, which avoids the entire drive component occupying too much height space. While ensuring the compactness of the structure, it also enables the lead screw 5 to rotate continuously and stably.

[0035] The frame 1 has a recessed connecting cavity 1a on its side. The lead screw 5 is located in the connecting cavity 1a. The guide rail 3 is in the shape of a long plate and is fixed to the port of the connecting cavity 1a. The slider 4 has a guide hole 4c that matches the guide rail 3 and the guide rail 3 passes through the guide hole 4c of the slider 4.

[0036] Since slider 4 is always connected to guide rail 3, and slider 4 is also threadedly connected to lead screw 5, slider 4 will move smoothly up and down along guide rail 3 as lead screw 5 continues to rotate.

[0037] The spray assembly includes a connecting rod 9 and a spray head 10. The inner end of the connecting rod 9 is fixed to the slider 4, and the spray head 10 is fixed to the outer end of the connecting rod 9. The spray head 10 has a water outlet 10a at its end and a water inlet 10b on its side for connection to a water pipe. The water inlet 10b communicates with the water outlet 10a.

[0038] The number of connecting rods 9 is several, and the connecting rods 9 are connected end to end. The innermost connecting rod 9 is fixedly connected to the slider 4, and the outermost connecting rod 9 is fixedly connected to the spray head 10.

[0039] The connecting rod 9 allows the spray head 10 to be kept as far away from the slider 4 as possible, preventing excessive water mist from entering the slider 4. Furthermore, the detachable connection of several connecting rods 9 allows for the adjustment of the position of the spray head 10 accordingly.

[0040] The slider 4 includes a block-shaped body 4a and a block-shaped body 4b. The connecting cylinder 4a1 is fixedly connected to the body 4a. After the body 4a and the body 4b are fastened together, the guide hole 4c is formed between them.

[0041] After the main body 4a and the second main body 4b are connected by fasteners, a guide hole 4c is formed between them. At the same time, the connecting cylinder 4a1 is located on the main body 4a. This structure allows the entire slider 4 to be easily connected to the frame 1.

[0042] A flexible washer 11 is fixedly connected to the main body 4a. When the main body 4a moves, the washer 11 can abut against the frame 1.

[0043] The washer 11 prevents rigid contact between the main body 4a and the frame 1.

[0044] There are two washers 11, which are fixed to the upper and lower parts of the main body 4a, respectively.

[0045] The two washers 11 ensure that the main body 4a will not make rigid contact with the frame 1 when it moves up or down.

[0046] The height of the first body 4a is greater than the height of the second body 4b. The upper end of the first body 4a extends beyond the upper part of the second body 4b, and the lower end of the first body 4a extends beyond the lower part of the second body 4b.

[0047] This structure can prevent contact between the main body 4b and the frame 1.

[0048] The marking component includes an L-shaped label 12 and several vertically arranged scale marks on the frame 1. The inner end of the label 12 is fixed to the outer side of the body 4b, and the inner end of the label 12 is adjacent to the scale marks.

[0049] The scale markings on the frame 1 are either numerical markings or a ruler directly fixed to the frame 1. When the slider 4 moves, the scale plate 12 on it moves accordingly. Since the scale plate 12 is adjacent to the scale markings, the operator can intuitively understand the height position of the spray assembly.

[0050] This spray device for testing the water resistance of textiles can stably spray water mist onto various parts of the textile being tested because the height of the spray components can be adjusted. At the same time, the spray head is located far from the slider, thus preventing excessive water mist from entering the slider's transmission structure, resulting in relatively high stability.

[0051] The drive unit and the lead screw are arranged adjacent to each other on the left and right sides, which reduces the space occupied in the height position. Its structure is also relatively compact and has high application value.

[0052] In addition, the long, flat guide rail ensures smooth movement of the slider, further improving its stability.

[0053] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
