Description

Technical Field

[0001] The invention relates to the technical field of grey cloth, in particular to a process for producing grey cloth with copper-based antibacterial coating. Background Art

[0002] Grey cloth is the basic material for garment production. Its quality and material determine the comfort and quality of the garment. According to the specific use of the grey cloth, the coating spraying technology can be used to further process the grey cloth.

[0003] The existing grey cloth spraying device only sprays and cures one side of the grey cloth in a single process. In specific operations, the two independent spraying processes not only reduce the overall processing efficiency, but also increase energy consumption in steps such as grey cloth conveying and paint curing, greatly increasing production costs. In addition, in order to obtain a sufficient contact area for the conveying rollers to push the grey cloth, the existing spraying device usually requires the conveying rollers to be staggered and contacted on both sides of the grey cloth. When the paint is not cured after spraying, the contact between the conveying rollers and the grey cloth can easily cause problems such as coating shedding, which is not practical to use. In addition, the existing grey cloth spraying device usually relies on fixed nozzles to spray the paint. However, this spraying method is affected by the distribution position of the nozzles, and the sprayed paint is difficult to be evenly spread on the grey cloth, which has certain limitations in use. In view of the above problems, it is necessary to improve the existing equipment. Summary of the invention

[0053] 3: Curing the coating in the curing room;

[0054] a. The external hot air delivery device delivers dry hot air into the curing chamber 4 through the air inlet 16, and the dry hot air heats and dries the grey cloth 14 and the coating;

[0055] b. The external waste gas recovery device extracts the waste gas in the curing chamber 4 through the gas outlet 17 to balance the air pressure in the curing chamber 4.

[0056] A copper-based antibacterial coating fabric production device, such as Figure 1 and Figure 2 As shown, an unwinding device 2 and a rewinding device 3 are fixedly installed on the left side of the frame 1, and the unwinding device 2 is arranged on the left side of the rewinding device 3.

[0057] In a further embodiment, a tension adjusting device 12 is provided between the unwinding device 2 and the first feed guide roller group 5 and between the rewinding device 3 and the first discharge guide roller group 6, and the tension adjusting device 12 is fixedly installed inside the frame 1, and the two tension adjusting devices 12 are respectively located at both ends of the grey cloth 14, so that the two tension adjusting devices 12 cooperate to adjust the tension of the entire grey cloth 14 during the conveying process.

[0058] like Figure 1 As shown, the rotation direction of the first feed guide roller group 5 and the second feed guide roller group 7 is opposite to the rotation direction of the first discharge guide roller group 6 and the second discharge guide roller group 8. The first feed guide roller group 5, the first discharge guide roller group 6, the second feed guide roller group 7 and the second discharge guide roller group 8 all rotate along the moving track of the grey cloth 14, and at the same time, the auxiliary power is increased for the grey cloth 14 during the rotation process.

[0059] like Figure 1 and Figure 3 As shown, a curing chamber 4 is fixedly installed on the right side of the frame 1, and a first feed guide roller group 5, a first discharge guide roller group 6, a second feed guide roller group 7 and a second discharge guide roller group 8 are rotatably installed inside the curing chamber 4.

[0060] In a further embodiment, the first feed guide roller group 5, the first discharging guide roller group 6, the second feed guide roller group 7 and the second discharging guide roller group 8 are all arranged to consist of six guide rollers, and the first feed guide roller group 5, the first discharging guide roller group 6, the second feed guide roller group 7 and the second discharging guide roller group 8 are respectively engaged with a chain 15, and the chain 15 synchronizes the six guide rollers on the first feed guide roller group 5. Similarly, the corresponding chain 15 synchronizes the guide rollers on the first discharging guide roller group 6, the second feed guide roller group 7 and the second discharging guide roller group 8, so that the corresponding first motor 9 drives the first feed guide roller group 5 or the first discharging guide roller group 6 or the second feed guide roller group 7 or the second discharging guide roller group 8 to rotate synchronously.

[0061] like Figure 1 As shown, the first discharge guide roller group 6 is arranged on the inner side of the first feed guide roller group 5, and the second feed guide roller group 7 is arranged on the inner side of the first discharge guide roller group 6, and the second discharge guide roller group 8 is arranged on the inner side of the second feed guide roller group 7. The rear ends of the first discharge guide roller group 6, the second discharge guide roller group 8, the first feed guide roller group 5 and the second feed guide roller group 7 all penetrate the frame 1 and are connected to the corresponding first motor 9. The first motor 9 provides power for the first feed guide roller group 5, the first discharge guide roller group 6, the second feed guide roller group 7 and the second discharge guide roller group 8, so that the first feed guide roller group 5, the first discharge guide roller group 6, the second feed guide roller group 7 and the second discharge guide roller group 8 contact and assist in pushing the grey cloth 14 to move along a predetermined track.

[0062] like Figure 1 , Figure 4 and Figure 5 As shown, a first spraying mechanism 10 is fixedly installed on the upper left side of the frame 1.

[0063] In a further embodiment, the first spraying mechanism 10 and the second spraying mechanism 11 both include a protective cover 111, a fixed shaft 112, a rotating head 113, a coating cavity 114, an air cavity 115, a coating nozzle 116, an air nozzle 117, an external gas delivery device, an external coating delivery device, a second motor 118 and a gas-liquid slip ring 119, the protective cover 111 is fixed on the frame 1 at both ends, and the fixed shaft 112 is fixedly installed on the upper side of the protective cover 111, and the rotating head 113 is rotatably installed at the bottom of the fixed shaft 112, a coating cavity 114 is opened on the lower side of the rotating head 113, and an air cavity 115 is opened on the upper side of the rotating head 113, a plurality of coating nozzles 116 and air nozzles 117 are staggered at the bottom of the rotating head 113, and the coating nozzles 116 and the coating cavity 114 are staggered. The second motor 118 is fixedly mounted on the protective cover 111, and the second motor 118 is connected to the rotating head 113. A gas-liquid slip ring 119 is installed between the rotating head 113 and the fixed shaft 112. The external gas delivery device and the air cavity 115 as well as the external paint delivery device and the paint cavity 114 are connected through the gas-liquid slip ring 119. The protective cover 111 closes the spraying processing space to a certain extent, avoiding the spray paint from escaping and polluting the surrounding environment. When the rotating head 113 rotates, the paint nozzle 116 and the gas nozzle 117 also rotate accordingly. The paint sprayed by the rotating paint nozzle 116 is more uniform. At the same time, the rotating gas nozzle 117 disturbs the sprayed paint, which further improves the uniformity of the spraying.

[0064] like Figure 1 , Figure 6 and Figure 7 As shown, a second spraying mechanism 11 is fixedly installed on the right side of the frame 1, and the second spraying mechanism 11 is arranged inside the curing chamber 4, an air inlet 16 is opened on the upper side of the curing chamber 4, and the air inlet 16 is connected to an external hot air conveying device, and an air outlet 17 is provided on the lower side of the curing chamber 4, and the air outlet 17 is connected to an external exhaust gas treatment device.

[0065] In a further embodiment, both ends of the reversing assembly 13 are rotatably connected to the frame 1, and the reversing assembly 13 is arranged inside the curing chamber 4. The reversing assembly 13 guides the reversal of the grey cloth 14, so that the grey cloth 14 passing through the first feed guide roller group 5 and the second feed guide roller group 7 changes a direction and contacts the first discharge guide roller group 6 and the second discharge guide roller group 8.

[0066] like Figure 1As shown, one end of the grey cloth 14 is fixed on the unwinding device 2, and the other end of the grey cloth 14 is fixed on the winding device 3. The grey cloth 14 sequentially passes through the tension adjusting device 12 between the unwinding device 2 and the first feed guide roller group 5, the first spraying mechanism 10, the first feed guide roller group 5, the second feed guide roller group 7, the reversing component 13, the second spraying mechanism 11, the second discharge guide roller group 8, the first discharge guide roller group 6, and the tension adjusting device 12 between the first discharge guide roller group 6 and the winding device 3. At this time, the grey cloth 14 is guided by the first feed guide roller group 5 and the second feed guide roller group 7 and is in a spiral shape. After entering the curing chamber 4 and passing through the reversing assembly 13, the grey cloth 14 passes through the first discharge guide roller group 6 and the second discharge guide roller group 8 and leaves the curing chamber 4. At this time, the grey cloth 14 is also spiral-shaped. The special structure allows the grey cloth 14 to always keep in contact with the first feed guide roller group 5 and the second feed guide roller group 7 through the same surface when passing through the first feed guide roller group 5 and the second feed guide roller group 7. Similarly, when the grey cloth 14 passes through the first discharge guide roller group 6 and the second discharge guide roller group 8, the grey cloth 14 always keeps in contact with the first discharge guide roller group 6 and the second discharge guide roller group 8 through the same surface.

[0067] During use, the unwinding device 2 releases the grey cloth 14, and the rewinding device 3 rewinds the grey cloth 14. The two tension adjusting devices 12 adjust the tension of the grey cloth 14. The grey cloth 14 first contacts the first spraying mechanism 10. At this time, the external paint conveying device conveys paint to the paint cavity 114 through the gas-liquid slip ring 119, and the paint is sprayed through the paint nozzle 116. At the same time, the external gas conveying device conveys air to the air cavity 115 through the gas-liquid slip ring 119, and the gas is sprayed through the gas nozzle 117. At the same time, the second motor 118 drives the rotating head 113 to rotate, so that the paint nozzle 116 sprays paint during rotation, and the gas nozzle 117 distributes gas during rotation, and the gas further stirs the sprayed paint, so that the paint is evenly sprayed on the grey cloth 14. The cloth 14 enters the curing chamber 4 and bypasses the first feed guide roller group 5 and the second feed guide roller group 7 in turn. After the grey cloth 14 leaves the curing chamber 4, it bypasses the reversing component 13. At this time, the grey cloth 14 turns around and passes through the second spraying mechanism 11. Similarly, the second spraying mechanism 11 completes the spraying process on the other side of the grey cloth 14. Then the grey cloth 14 enters the curing chamber 4 and passes through the second discharge guide roller group 8 and the first discharge guide roller group 6 in turn. The external hot air conveying device conveys hot air into the curing chamber 4 through the air inlet 16, so that the hot air heats and dries the grey cloth 14 in the curing chamber 4, so that the grey cloth 14 completes the curing process. Then the external exhaust gas recovery device extracts the exhaust gas in the curing chamber 4 through the exhaust port 17, which completes all the work.
