Description

Technical Field

[0001] The invention relates to the technical field of fabric spraying, and in particular to an ultraviolet fabric surface coating device and a coating method. Background Art

[0002] In today's society, people usually apply UV protection coatings to the surface of fabrics to prevent harmful ultraviolet rays and protect the skin from UV damage. Coating devices are widely used in textiles, clothing and other fabric processing.

[0003] The fabric is usually fed into the coater by an automated conveying system and passed through a curing oven etc. In an efficient coating device, the conveying speed and tension control of the fabric are very important to avoid fabric stretching, deformation or uneven coating.

[0004] However, in the prior art, during the winding and conveying process of the fabric, the rotation speeds of the winding roller and the conveying roller are the same, but as the fabric on the conveying roller decreases, the linear speed of the fabric on the conveying roller decreases. Similarly, as the fabric on the winding roller increases, the linear speed of the fabric on the winding roller increases, which causes the fabric to be stretched and deformed during this process, and the ultraviolet protection layer of the fabric is damaged, thereby affecting the anti-ultraviolet effect of the fabric. Therefore, a UV fabric surface coating device and coating method are urgently needed. Summary of the invention

[0005] In view of the above technical problems, the technical solution adopted by the present invention is: a UV fabric surface coating device, including a supporting mechanism and two groups of average speed mechanisms, the supporting mechanism includes a bottom plate and two groups of mountain-shaped frames, the two groups of mountain-shaped frames are symmetrically slidably installed on the bottom plate, two pairs of concave plates are symmetrically installed on the vertical frames of the mountain-shaped frames, and a hoisting roller is detachably installed between each pair of concave plates, and spray pipe racks are fixedly installed on the brackets of the mountain-shaped frames, and the two groups of spray pipe racks are tightly slidably installed, one group of spray pipe racks is slidably installed inside the other group of spray pipe racks, and multiple groups of spray components are evenly arranged on the spray pipe racks; The two groups of average speed mechanisms are symmetrically arranged on the vertical frame of a group of mountain frames. The average speed mechanism includes a driven frame and a planetary disk. The planetary disk is fixedly installed with the corresponding concave disk. The driven frame is longitudinally slidably installed on the vertical frame. Multiple groups of T-frames are radially slidably installed on the planetary disk. A receiving frame is slidably installed between adjacent T-frames. The roller of the driven frame is in close contact with the fabric on the winch roller. The U-frame of the driven frame is in contact with the arc surface of the T-frame. The distance from the arc surface of the T-frame to the axis center of the concave disk is the same as the distance from the surface of the fabric on the corresponding winch roller to the axis center of the concave disk. Transmission belts are arranged on the T-frames of the two groups of average speed mechanisms.

[0006] Furthermore, the support mechanism also includes a bidirectional screw, which is rotatably mounted on the vertical frame at one end of the two sets of mountain-shaped frames, and is rotatably mounted on the pin of the bottom plate. The bidirectional screw is threadedly matched with the vertical frame, and a turntable is provided at the end of the bidirectional screw. The turntable is rotated to drive the two sets of mountain-shaped frames to move toward or away from each other. When the mountain-shaped frames move, the two sets of concave disks are driven to move to adapt to the width of the hoisting roller and fix the hoisting roller, thereby adapting to the width of the ultraviolet fabric. In this process, the two sets of spray pipe racks slide relative to each other to coat ultraviolet fabrics of different widths.

[0007] Furthermore, a curing mechanism is provided on the seat pin of the bottom plate, and a guide column is also provided on the seat pin, and the guide column is located below the curing mechanism. A guide column is also provided on the bracket of the mountain frame, and the guide column is located below the spraying tube rack. The fabric contacts the bottom of the guide column, and the top of the guide column contacts the fabric. The fabric passes under the guide column, and contacts the top of the guide column. The guide column and the guide column convey the fabric, which is convenient for the spray assembly on the spraying tube rack to coat the fabric, and at the same time, it is convenient for the curing mechanism to cure the coated fabric.

[0008] Furthermore, the spray assembly includes a nozzle and a spray spring. A sliding disk is arranged above the nozzle. The nozzle is slidably installed on the spray pipe rack, and the bottom of the nozzle is in contact with the arc wedge of the spray pipe rack; the spray spring is arranged inside the disk hole, and the spray spring is arranged between the sliding disk and the disk hole. A nozzle hole is arranged inside the sliding disk, and the nozzle holes of the two coaxial groups of spray assemblies on the two groups of spray pipe racks are in bite contact with the nozzle. According to the width of the ultraviolet fabric, the number of spray assemblies on the spray tube rack is adjusted to change the spray width, and the two groups of spray tube racks slide relative to each other. There are two groups of spray tube racks, one group of spray tube racks is slidably installed inside the other group of spray tube racks, and the nozzle of the spray assembly on the inner spray tube rack contacts and cooperates with the arc wedge of the outer spray tube rack, and the arc wedge pushes the nozzle on the inner spray tube rack to slide upward, and the spray springs corresponding to the overlapping nozzles are compressed until the overlapping spray assemblies are completely stored in the inner spray tube rack and slide to the inside of the outer spray tube rack, coaxial with the spray assembly of the outer spray tube rack, thereby changing the spray quantity of the spray assembly, the nozzle holes of the two coaxial groups of spray assemblies on the two groups of spray tube racks are in bite contact with the nozzles, and the paint flows from the spray assembly on the inner spray tube rack to the spray assembly on the outer spray tube rack coaxial with this group of spray assemblies, so as to realize stable spraying of the spray assembly on the outer spray tube rack.

[0009] Furthermore, the speed-averaging mechanism also includes a planetary wheel, which is rotatably mounted on the planetary disk, a convex column is provided on the T-frame, and a plurality of arc tracks are provided on the planetary wheel, one group of T-frames corresponds to one group of arc tracks, and the convex column of the T-frame is slidably mounted on the arc track. When the distance between the surface of the fabric on the hoisting roller and the axis changes, the fabric pushes the roller on the hoisting roller to drive the driven frame to slide on the vertical frame, and the U-frame of the driven frame drives the arc surface of the T-frame to move, and the T-frame slides on the planetary disk, and under the connection of the receiving frame, drives the remaining T-frames to slide on the planetary disk, and the convex column of the T-frame slides on the arc track, and the planetary disk and the planetary wheel slide relative to each other, thereby changing the distance between the arc surface of the T-frame and the axis of the concave disk, so that the distance from the arc surface of the T-frame to the axis of the concave disk is always equal to the distance from the surface of the fabric on the hoisting roller to the axis of the concave disk.

[0010] Furthermore, the T-frame is provided with multiple groups of tooth blocks, and the transmission belt is provided with grooves, and the tooth blocks are in contact with the grooves. The contact between the tooth blocks and the grooves ensures the stable transmission of the two groups of equal-speed mechanisms. When the distance from the arc surface of the T-frame of one group of equal-speed mechanisms to the axis of the concave disk increases, the length of the transmission belt is fixed, and the distance from the arc surface of the T-frame of the other group of equal-speed mechanisms to the axis of the concave disk decreases. Since the rollers of the driven frames of the two groups of equal-speed mechanisms are in contact with the fabrics on the corresponding hoisting rollers, the linear speeds of the T-frames of the two groups of equal-speed mechanisms are the same, so that the linear speeds of the fabrics on the two groups of hoisting rollers are the same, so that the material discharge speed is the same as the material collection speed during the fabric coating process, preventing the fabric from being stretched during the coating process and affecting the fabric's anti-ultraviolet function.

[0011] Furthermore, multiple sets of limit assemblies are arranged between the planetary gear and the concave disk, the limit assemblies include a limit ball and a limit spring, a limit rod is fixedly installed on the limit ball, the limit rod is slidably installed on the planetary gear, the limit spring is arranged between the planetary gear and the limit ball, the limit spring is slidably installed on the limit rod, and multiple sets of limit grooves are arranged on the concave disk, and the limit ball is in bite contact with the limit groove. The T-frame slides on the planetary disk, and the tooth block of the T-frame slides on the arc track, and the planetary disk and the planetary wheel rotate relative to each other. Since the planetary disk and the concave disk are fixedly installed, the planetary wheel and the concave disk rotate relative to each other, the limit spring is compressed, the limit rod slides on the planetary wheel, the limit groove and the limit ball are disconnected, the T-frame slides to the target position, and the limit ball continues to engage with the limit groove on the concave disk, limiting the relative position of the planetary wheel and the concave disk, thereby limiting the position of the T-frame on the planetary disk, ensuring stable transmission between the two sets of averaging mechanisms, so that the linear speed of the fabric on the hoisting rollers corresponding to the two sets of averaging mechanisms is the same, ensuring that the fabric is not stretched during coating.

[0012] Furthermore, a convex block is arranged inside the concave disk, and a concave hole is arranged at the end of the winding roller, and the convex block is engaged with the concave hole. The concave hole is engaged with the convex block, and when the concave disk rotates, the corresponding winding roller is driven to rotate, and when the winding roller rotates, the cloth is retracted and released.

[0013] The present invention also discloses a method for coating the surface of ultraviolet fabrics, which uses the above-mentioned ultraviolet fabric surface coating device and comprises the following steps:

[0014] Step 1: Install the winding roller with coated UV fabric on a pair of concave disks near the spray tube rack, install the winding roller for winding the coated UV fabric on a pair of concave disks near the curing mechanism, rotate the bidirectional lead screw to drive the two sets of mountain frames to move toward each other until the convex block of the concave disk is engaged with the concave hole of the winding roller;

[0015] Step 2: When the two groups of mountain-shaped racks move toward each other, the two groups of spray pipe racks are driven to slide toward each other. One group of spray pipe racks is slidably installed inside the other group of spray pipe racks. The nozzle of the spray assembly on the inner spray pipe rack contacts and cooperates with the arc wedge of the outer spray pipe rack. The arc wedge pushes the nozzle on the inner spray pipe rack to slide upward until the spray assembly of the inner spray pipe rack slides to the inside of the outer spray pipe rack and is coaxial with the spray assembly of the outer spray pipe rack, thereby changing the spray quantity of the spray assembly;

[0016] Step 3: The rollers of the driven frames of the two sets of averaging mechanisms are respectively closely contacted with the fabrics on the corresponding hoisting rollers. As the fabrics on the hoisting rollers change, the driven frames are driven to move longitudinally on the seat pins. The distance from the arc surface of the T-frame of the corresponding averaging mechanism to the axis of the concave disk is the same as the distance from the surface of the fabric on the corresponding hoisting roller to the axis of the concave disk.

[0017] Step 4: The curing mechanism cures the coated fabric, one set of winding rollers outputs the fabric, and the other set of winding rollers reels the fabric. Under the transmission action of the transmission belt, the transmission speed of the fabric on the two sets of winding rollers is the same, and the output and reeling of the UV fabric are completed at a uniform speed.

[0018] Compared with the prior art, the present invention has the following advantages: (1) The present invention is provided with a supporting mechanism, which uses a bidirectional lead screw to drive two groups of mountain-shaped frames to move toward or away from each other, thereby adjusting the distance between each pair of concave disks and the spraying range of the spray assembly on the spray pipe rack, thereby adapting to fabrics of different widths; (2) The present invention is provided with a coating mechanism, which uses the structural setting of the spray assembly to change the spraying quantity of the spray assembly when adapting to the spraying of the fabric width, and the nozzle holes of the two coaxial groups of spray assemblies on the two groups of spray pipe racks are in bite contact with the nozzles, and the paint is sprayed from the inside The spray assembly on the spray pipe rack flows to the spray assembly on the outside spray pipe rack which is coaxial with this group of spray assemblies, so as to realize stable spraying of the spray assembly on the outside spray pipe rack; (3) The present invention is provided with two groups of averaging mechanisms, and the driven frame is used to adjust the distance between the arc surface of the T-frame and the axis of the concave disk according to the thickness of the fabric on the concave disk. The contact between the tooth block and the groove ensures the stable transmission of the two groups of averaging mechanisms, so that the speeds of conveying cloth and winding cloth on the two groups of concave disks are the same, so as to prevent the cloth from being stretched during the coating process and affecting the anti-ultraviolet function of the fabric.

The roller 511 contacts and cooperates with the fabric on the hoisting roller 33 on the corresponding concave disk 31. As the fabric on the hoisting roller 33 increases, the roller 511 drives the driven frame 51 to move upward, and the fabric on the hoisting roller 33 decreases. The roller 511 drives the driven frame 51 to slide downward under the action of gravity; the T-frame 55 is evenly radially slidably installed on the planetary disk 53, and the end of the T-frame 55 is provided with an arc surface.

[0038] (34) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig.11 , Fig.12As shown, the planetary gear 54 is coaxial with the concave disk 31, and multiple groups of limiting components 56 are arranged between the planetary gear 54 and the corresponding concave disk 31. The limiting components 56 include a limiting rod 561, a limiting ball 562, and a limiting spring 563. The limiting ball 562 is fixedly installed with the limiting rod 561, and the limiting rod 561 is slidably installed on the planetary gear 54. The limiting spring 563 is arranged between the planetary gear 54 and the limiting ball 562. The limiting spring 563 is slidably installed on the limiting rod 561. Multiple groups of limiting grooves are arranged on the concave disk 31. , the limiting ball 562 engages with the limiting groove; the T-frame 55 slides on the planetary disc 53, the convex column 552 of the T-frame 55 slides on the arc track 541, and the planetary disc 53 and the planetary gear 54 rotate relative to each other. Since the planetary disc 53 and the concave disc 31 are fixedly installed, the planetary gear 54 and the concave disc 31 rotate relative to each other, the limiting spring 563 is compressed, the limiting rod 561 slides on the planetary gear 54, the limiting groove and the limiting ball 562 are disconnected, the T-frame 55 slides to the target position, and the limiting ball 562 and The limiting grooves on the concave plate 31 continue to engage, limiting the relative position of the planetary gear 54 and the concave plate 31, thereby limiting the position of the T-shaped frame 55 on the planetary plate 53; the T-shaped frames 55 of the two groups of average speed mechanisms are provided with a transmission belt 2, and multiple groups of tooth blocks 551 are provided on the T-shaped frame 55. The transmission belt 2 is provided with grooves, and the tooth blocks 551 are in contact with the grooves; the contact between the tooth blocks 551 and the grooves ensures the stable transmission of the two groups of average speed mechanisms. When the distance from the arc surface of the T-shaped frame 55 of one group of average speed mechanisms to the axis of the concave plate 31 increases, , the length of the transmission belt 2 is fixed, and the distance from the arc surface of the T-frame 55 of the other set of averaging mechanisms to the axis center of the concave disk 31 is reduced. Since the rollers 511 of the driven frames 51 of the two sets of averaging mechanisms are in contact with the fabrics on the corresponding hoisting rollers 33 respectively, the linear speeds of the T-frames 55 of the two sets of averaging mechanisms are the same, so that the linear speeds of the fabrics on the two sets of hoisting rollers 33 are the same, thereby achieving the same material discharge speed and material collection speed during the fabric coating process, preventing the fabric from being stretched during the coating process and affecting the fabric's UV protection function.

[0039] Working principle: the fabric to be coated is set on the hoisting roller 33, and the hoisting roller 33 with the fabric is set between a pair of concave disks 31 close to the spray pipe rack 42. The hoisting roller 33 of the fabric to be rolled up and coated is set between a pair of concave disks 31 close to the curing mechanism 15. The hoisting roller 33 is coaxial with the concave disk 31. The turntable 131 is rotated to drive the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 is threadedly matched with the vertical frame 121. The bidirectional lead screw 13 drives the two sets of mountain frames 12 to move toward each other until the protrusion 311 on the concave disk 31 contacts and matches with the concave hole 331 of the corresponding hoisting roller 33. Each pair of concave disks 31 adapts to the width of the hoisting roller 33 and fixes the hoisting roller 33, thereby adapting to the width of the ultraviolet fabric.

[0040] During this process, the mountain frame 12 drives the two groups of spray tube racks 42 to slide relative to each other, so that the spray range of the spray assembly 43 adapts to the width of the ultraviolet fabric for coating, saving paint; the two groups of spray tube racks 42 slide relative to each other, and the nozzle 431 of the spray assembly 43 on the inner spray tube rack 42 contacts and cooperates with the arc wedge 422 of the outer spray tube rack 42, and the arc wedge 422 pushes the nozzle 431 on the inner spray tube rack 42 to slide upward, and the spray spring 432 corresponding to this group of nozzles 431 is compressed until this group of spray components 43 is completely stored. To the internal spray pipe rack 42, and slide to the inside of the external spray pipe rack 42, coaxial with the spray assembly 43 of the external spray pipe rack 42, thereby changing the spray quantity of the spray assembly 43, the nozzle holes 4312 of the two coaxial groups of spray assemblies 43 on the two groups of spray pipe racks 42 are in bite contact with the nozzle 431, and the paint flows from the spray assembly 43 on the internal spray pipe rack 42 to the spray assembly 43 on the external spray pipe rack 42 coaxial with this group of spray assemblies 43, thereby achieving stable spraying of the spray assembly 43 on the external spray pipe rack 42.

[0041] The end of the UV fabric to be coated is passed from under the guide column 14, is located under the spray pipe rack 42 and the curing mechanism 15, and then passed from above the guide column 16, and fixed on the hoisting roller 33 of the fabric after winding up and coating, and the rollers 511 of the driven frames 51 of the two sets of equal-speed mechanisms are respectively in contact with the fabric on the hoisting roller 33; the paint box 41 and the motor 32 are started, the paint box 41 fills the spray pipe rack 42 with paint, and the paint is sprayed from the spray assembly 43, and the paint is evenly sprayed on the fabric, and the motor 32 drives the concave disk 31 on its output shaft to rotate, and the concave disk 31 drives the hoisting roller 33 thereon to rotate, thereby driving the pair of concave disks 31 to rotate, and the corresponding equal-speed mechanism of the pair of concave disks 31 rotates, and under the transmission action of the transmission belt 2, another set of equal-speed mechanisms is driven to rotate, thereby driving another pair of concave disks 31 and the hoisting roller 33 to rotate, completing the conveying and winding of the fabric, and the curing mechanism 15 cures the sprayed fabric.

[0042] In this process, as the amount of fabric to be sprayed decreases, the distance between the surface of the fabric to be sprayed and the axis of the concave disk 31 decreases, and the roller 511 of the driven frame 51 corresponding to the pair of concave disks 31 is in contact with the fabric to be sprayed. The driven frame 51 of this group of average speed mechanisms moves downward, and the distance between the arc surface of the T-shaped frame 55 of this group of average speed mechanisms and the axis of the concave disk 31 decreases; similarly, as the amount of coated fabric on the hoisting roller 33 corresponding to the other pair of concave disks 31 increases, the roller 511 of the driven frame 51 corresponding to the other pair of concave disks 31 is in contact with the coated fabric. The fabrics are in contact, and the coated fabrics push the driven frame 51 of the averaging mechanism to move upward, so the distance from the arc surface of the T-frame 55 of the averaging mechanism to the axis of the concave disk 31 increases. Since the length of the transmission belt 2 is fixed, the linear speeds of the arc surfaces of the T-frames 55 on the two sets of averaging mechanisms are the same. The contact between the tooth block 551 and the groove ensures the stable transmission of the two sets of averaging mechanisms, so that the speeds of the conveying and winding fabrics on the two sets of concave disks 31 are the same, preventing the fabric from being stretched during the coating process and affecting the UV protection function of the fabric.

[0043] When the T-shaped frame 55 of the speed averaging mechanism slides on the planetary disk 53, the convex column 552 of the T-shaped frame 55 slides on the arc track 541, and the planetary disk 53 and the planetary wheel 54 rotate relative to each other. Since the planetary disk 53 and the concave disk 31 are fixedly installed, the planetary wheel 54 and the concave disk 31 rotate relative to each other, the limit spring 563 is compressed, the limit rod 561 slides on the planetary wheel 54, the limit groove and the limit ball 562 are disconnected, the T-shaped frame 55 slides to the target position, and the limit ball 562 continues to engage with the limit groove on the concave disk 31, limiting the relative position of the planetary wheel 54 and the concave disk 31, thereby limiting the position of the T-shaped frame 55 on the planetary disk 53, ensuring stable transmission between the two sets of speed averaging mechanisms, so that the linear speed of the fabric on the hoisting roller 33 corresponding to the two sets of speed averaging mechanisms is the same, ensuring that the fabric is not stretched during coating.

[0044] The present invention also discloses a method for coating the surface of ultraviolet fabrics, which uses the above-mentioned ultraviolet fabric surface coating device and comprises the following steps:

[0045] Step 1: Install the winding roller 33 with the coated UV fabric on a pair of concave plates 31 near the spray pipe rack 42, install the winding roller 33 for winding the coated UV fabric on a pair of concave plates 31 near the curing mechanism 15, rotate the bidirectional lead screw 13, and drive the two sets of mountain frames 12 to move toward each other until the convex block 311 of the concave plate 31 is engaged with the concave hole 331 of the winding roller 33;

[0046] Step 2: When the two groups of mountain-shaped frames 12 move toward each other, the two groups of spray pipe racks 42 are driven to slide toward each other, and the nozzle 431 of the spray assembly 43 on the inner spray pipe rack 42 contacts and cooperates with the arc wedge 422 of the outer spray pipe rack 42, and the arc wedge 422 pushes the nozzle 431 on the inner spray pipe rack 42 to slide upward until the spray assembly 43 of the inner spray pipe rack 42 slides to the inside of the outer spray pipe rack 42 and is coaxial with the spray assembly 43 of the outer spray pipe rack 42, thereby changing the spray quantity of the spray assembly 43;

[0047] Step 3: The rollers 511 of the driven frames 51 of the two sets of averaging mechanisms are respectively closely contacted with the fabrics on the corresponding hoisting rollers 33. As the fabrics on the hoisting rollers 33 change, the driven frames 51 are driven to move longitudinally on the seat pins 112. The distance from the arc surface of the T-shaped frame 55 of the corresponding averaging mechanism to the axis of the concave disk 31 is the same as the distance from the surface of the fabric on the corresponding hoisting roller 33 to the axis of the concave disk 31.

[0048] Step 4: The curing mechanism 15 cures the coated fabric, one set of winding rollers 33 outputs the fabric, and the other set of winding rollers 33 reels the fabric. Under the transmission action of the transmission belt 2, the transmission speed of the fabric on the two sets of winding rollers 33 is the same, and the output and reeling of the UV fabric are completed at a uniform speed.

[0049] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
