Description

Technical Field

[0001] This utility model relates to a spraying device, and more particularly to an antibacterial coating atomization spraying device for crepe fabric. Background Technology

[0002] With the continuous advancement of science and technology and the development of textile technology, the production of crepe de chine fabric has gradually become mechanized and automated, significantly improving production efficiency and enabling better control over fabric quality and specifications. The production of crepe de chine fabric involves stages such as raw material selection, silk reeling, twisting, weaving, dyeing, and finishing. To meet market demands and hygiene standards, an antibacterial coating is sprayed onto the surface of the crepe de chine fabric for high-quality output. This treated fabric can be used to make work clothes, medical dressings, etc., effectively preventing bacterial transmission, reducing bacterial growth, lowering the risk of infection, and protecting the health of wearers.

[0003] Currently, the processing of crepe fabric involves sequentially passing the fabric through an input roller, a spray box, and an output roller. The rotation of two rollers drives the fabric into the spray box, where atomizing nozzles apply an antibacterial coating. Finally, the fabric is pulled out by the rollers, completing the antibacterial coating process. However, this method results in a relatively damp surface, with excess coating dripping down, allowing dust and bacteria to adhere and affecting the antibacterial quality of the crepe fabric. Therefore, it is necessary to design a high-quality atomized spraying device that reduces coating waste and enhances the fabric's antibacterial properties. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide an antibacterial coating atomization spraying device for crepe fabric, which realizes the purpose of high-quality fabric processing by atomization spraying device, reduces coating waste, and increases the antibacterial properties of fabric.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An antibacterial coating atomizing spraying device for crepe fabric includes a spraying box, with conveying rollers at both the input and output ends of the spraying box. Spray head assemblies are installed on both the upper and lower sides inside the spraying box. A material box connected to the two spray head assemblies is installed outside the spraying box. A pressure chamber is located in the middle of the spraying box, with the two spray head assemblies located on the upper and lower sides inside the pressure chamber. A receiving hopper is provided through the bottom of the pressure chamber, and a collecting trough is provided at the lower end of the receiving hopper. A receiving plate is vertically installed in the collecting trough. A partition is provided above the receiving plate in the pressure chamber for high-pressure spraying of the fabric.

[0007] Preferably, the receiving hoppers are distributed parallel to the input and output ends of the material in the pressure chamber, and there are multiple sets of receiving hoppers arranged in parallel in the pressure chamber.

[0008] Preferably, the collecting trough is located below the pressurizing box, the material box is equipped with a pressurizing pump, and the pressurizing pump and the collecting trough are connected by the same receiving pipe.

[0009] Preferably, the booster pump is connected in a continuous manner to the two nozzle assemblies, and the input end of the booster pump is connected in a continuous manner to the receiving pipe. The output end of the booster pump is provided with a booster hood, and the narrow end of the booster hood is set downward for pressurizing the output material.

[0010] Preferably, both ends of the booster box are provided with a retractable portion, and a flexible sheet is provided on the outside of the retractable portion, the flexible sheet being made of silicone material.

[0011] Preferably, the spray box is equipped with an extrusion assembly and a drying assembly at the discharge end of the pressurization box for high-quality output through the fabric.

[0012] Preferably, the extrusion assembly includes two extrusion rollers, the outer surface of which is covered with an absorbent cotton layer. The two sets of extrusion rollers are arranged longitudinally, and a filling block is sleeved through both ends of each extrusion roller. A connecting seat is sleeved on the outside of each filling block. A bearing seat that fits into the connecting seat is provided at the end of each extrusion roller. A connecting seat is provided on the outside of the bearing seat, and the connecting seat is perpendicularly connected to the spray box for finishing the fabric coating.

[0013] Preferably, the air-drying assembly includes multiple finishing rollers and two symmetrically distributed convection boxes. The multiple finishing rollers are distributed in a wave-like pattern in the spray box. The convection boxes are externally connected to a fan for high-quality output of the fabric.

[0014] Compared with existing technologies, the antibacterial coating atomizing spraying device for crepe fabric provided by this utility model can process fabrics with high quality, reduce paint waste, and increase the antibacterial properties of the fabric. Specifically, by using a pressure box, multiple spraying spaces can be set in the spraying box, allowing the atomized paint to quickly fill the box and be sprayed at high pressure onto the surface of the input fabric, avoiding excess paint on the fabric and increasing the comprehensiveness of the fabric spraying; furthermore, by using a collection hopper and collection plate in the pressure box, excess paint can be quickly collected and recycled, reducing paint waste.

[0015] Furthermore, the extrusion and drying components reduce paint residue on the fabric, extruding and removing excess paint while feeding material into the gaps of the crepe fabric to increase the fullness of the coating. The fabric is conveyed by multiple finishing rollers in a wave-like distribution, which not only allows for rapid drying and reduces the adhesion of dust and bacteria, but also increases the stability of fabric transport, reduces fabric wear, and improves the quality of the fabric produced by the spraying device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] As attached Figure 1 To be continued Figure 6 As shown in the embodiment of this utility model, the antibacterial coating atomizing spraying device for crepe fabric is used. When the spraying box 1 is used to spray the fabric with antibacterial coating, the conveying rollers 2, which are set at both the input and output ends of the spraying box 1, are used to pass the fabric through the input end, through the spraying box 1 and out from the output end. During the spraying operation, the antibacterial coating material is sent into the spraying box 1. The nozzle groups 4 on the upper and lower sides of the spraying box 1 are used to spray the antibacterial material on both the upper and lower sides of the fabric. By rotating the conveying rollers 2 at the input and output ends, the fabric is continuously fed into the spraying box 1 and the sprayed fabric is output, so as to realize the continuous processing of the fabric. To address the issues of excess paint on the fabric surface, paint dripping, and dust and bacteria adhesion to the output fabric, a pressure chamber 5 can be installed in the middle of the spraying box 1. Two nozzle assemblies 4 are positioned on the upper and lower sides of the pressure chamber 5, with the fabric passing through the middle of the two nozzle assemblies 4, allowing the two nozzle assemblies 4 to spray the upper and lower sides of the fabric. Next, a collection hopper 6 is installed through the bottom of the pressure chamber 5, with the hopper opening upwards. At the lower end of the collection hopper 6, an inwardly converging collection groove 7 is installed. The vertically arranged collection plate 9 in the collection groove 7 can collect and gather excess paint in the spraying box 1. At the same time, a partition 10 located above the collection plate 9 in the pressure chamber 5 can be used to create multiple spraying spaces in the pressure chamber 5, facilitating the rapid filling of the pressure chamber 5 with sprayed paint. The paint is then sprayed at high pressure onto the fabric, fully spraying the fabric surface, reducing paint usage, avoiding paint waste, and improving the spraying quality of the spraying device.

[0028] It is worth noting that, for example Figure 2 As shown, since the fabric is input and sprayed from the input end, the material collection hopper 6 and the material input and output ends of the pressure box 5 need to be set in parallel so that the dropped paint can be collected more quickly using the material collection hopper 6. At the same time, multiple sets of material collection hoppers 6 can be set, and multiple sets of material collection hoppers 6 can be set in parallel in the pressure box 5 to increase the rate and convenience of paint recycling.

[0029] Secondly, in order to achieve full coating of the fabric, such as Figure 2 and 3As shown, in some embodiments, the collecting trough 7 can be positioned below the pressurizing box 5, and a booster pump 12 can be installed on the material box 3. This booster pump 12 utilizes existing water pump technology for liquid delivery and can deliver paint to the spraying device. A receiving pipe 8 is then connected between the booster pump 12 and the collecting trough 7. Next, the output end of the booster pump 12 is connected to two nozzle assemblies 4, and the input end of the booster pump 12 is connected to the material box 3, completing the setup of the booster pump 12. Connecting the end of the receiving pipe 8 to the input end of the booster pump 12 allows for the collection and recycling of paint. Simultaneously, a paint pressurization structure is added to the spraying device. By adjusting the different speeds of the booster pump 12, the pressure of the input paint can be intelligently controlled, facilitating a wider and finer spraying of the nozzle assembly 4 onto the fabric, saving spraying time and improving the fullness of fabric coating.

[0030] Furthermore, for high-pressure spraying of materials, such as Figure 4 As shown, in some embodiments, a pressure boosting shroud 11 may also be provided at the output end of the booster pump 12. The narrow end of the pressure boosting shroud 11 is set downward, and the output material is pressurized again by taking advantage of the high flow rate of the small orifice.

[0031] To reduce paint overflow, such as Figure 2 and 3 As shown, in some embodiments, the two ends of the pressurization box 5 can be set as inwardly contracting gathering parts 13, and the fabric passes through the middle of the gathering part 13. The gathering part 13 blocks the paint with a larger area, increasing the cleanliness of the spraying process. Then, a flexible sheet 14 of silicone material can be set on the outside of the gathering part 13 to reseal the gap between the gathering part 13 and the fabric, thereby improving the sealing effect of the paint.

[0032] In order to improve the antibacterial properties of the fabric processed by the spraying device and avoid the adhesion of external dust and bacteria, in some embodiments, an extrusion assembly 15 and a drying assembly can be provided at the discharge end of the pressurization box 5 in the spraying box 1. The discharge ends of the extrusion assembly 15 and the drying assembly are opposite to the discharge port of the spraying box 1, so that the processed fabric is output with high quality.

[0033] Among them, such as Figure 2 and 6As shown, in some embodiments, the extrusion assembly 15 can use two extrusion rollers 19. The outer surface of the extrusion rollers 19 can be covered with an absorbent cotton layer 20, and the two extrusion rollers 19 are arranged longitudinally. Then, a filler block 18 of absorbent cotton material is sleeved through both ends of the extrusion rollers 19, and a connecting seat 16 is sleeved on the outside of the filler block 18. Then, a bearing seat 17 is provided at the end of the extrusion roller 19. The bearing seat 17 is tightly fitted with the connecting seat 16 on one side, and a bearing is provided in the bearing seat 17 to fix the extrusion roller 19 to the bearing. The extrusion roller 19 can rotate at an angle using the bearing. Finally, a connecting seat is provided on the outside of the bearing seat 17, and the connecting seat is vertically connected to the spray box 1 to install the position of the extrusion roller 19. By using the two extrusion rollers 19, the upper and lower sides of the fabric can be extruded, excess paint can be absorbed, and the paint can enter the gaps of the crepe fabric, increasing the fullness of the fabric processing.

[0034] Secondly, such as Figure 2 and 5 As shown, after squeezing out excess paint, the fabric needs to be air-dried to ensure fabric quality. In some embodiments, the air-drying assembly can use multiple finishing rollers 21 and two symmetrically distributed convection boxes 22. The multiple finishing rollers 21 can be distributed in a wave-like manner in the spray box 1. This distribution allows the fabric to fully expand during the air-drying process, increasing the contact area with convective air. Then, a fan 23 is connected to the outside of the convection box 22. Using the air transport of the fan 23, convective air can be formed on both sides of the multiple finishing rollers 21 to air-dry the fabric, achieving dry output, avoiding the adhesion of dust and bacteria, increasing the stability of fabric transport, reducing fabric wear, and improving the quality of the fabric produced by the spraying device.

[0035] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
