Description

Technical Field

[0001] This invention relates to the field of textile fabric processing technology, and in particular to a surface coating device for processing waterproof fabrics. Background Technology

[0002] Waterproof fabric is a new type of fabric. It is made by coating the surface of the fabric with a waterproof coating. After it dries, the surface becomes water-resistant. Waterproof fabric is often used in outdoor equipment, such as car roofs, tents, and outdoor jackets.

[0003] Existing waterproof fabrics have the following problems in their production: Coating is the most common method in waterproof fabric production, and the current coating method is immersion coating. This method involves brushing a layer of fabric onto the surface. However, due to the various complex scenarios that occur during the use of the finished product, such as folding, this coating method only forms a film on the surface. After prolonged folding, the surface waterproof layer and the inner yarn layer will break, tear, or be pulled apart. This is because there are no anchoring points on the coating and yarn layers to reinforce them. Existing technologies cannot easily solve this problem. Therefore, there is an urgent need for surface coating equipment for waterproof fabric processing to solve the above problems. Summary of the Invention

[0004] Addressing the technical problem that existing waterproof fabrics lack anchoring structures on the waterproof coating and yarn layers to reinforce the waterproof fabric layer and yarn layer, this invention proposes a surface coating device for waterproof fabric processing.

An injection hole is opened at the center position of the injection head, and an air guide pipe is connected to the air inlet end of the injection hole. The air guide pipe is connected to the air inlet ring. A feed hole is opened on one side of the injection head, and the feed hole and the injection hole are obliquely connected.

[0009] Preferably, three leveling rollers are fixed between the inner walls of the two sides of the main unit box by bearings, and the outer circumferential walls of the three leveling rollers are in contact with the fabric body.

[0010] Preferably, a first drying chamber and a second drying chamber are bolted together between the two inner walls of the main unit housing and between the two drying guide rollers, and both the first drying chamber and the second drying chamber are equipped with drying mechanisms.

[0011] Preferably, the drying mechanism includes a swing plate hinged between the inner walls of the first and second drying chambers. A return spring is fixed to one side of the swing plate by bolts, and the other side of the return spring is fixed to the inner wall of the corresponding first and second drying chambers. A rotating rod is fixed to the inner wall of the first and second drying chambers by bearings. A first bevel gear set is provided at the axis position of the rotating rod and the swing plate.

[0012] Preferably, the drying mechanism further includes a drive chamber formed by the inner walls of the first and second drying chambers. A drive rod sleeve is fitted onto the inner wall of the drive chamber via two bearings. A second bevel gear set is provided between the drive rod sleeve and one end of the rotating rod. Limiting springs are fixed at the top and bottom of the drive chamber. A roller seat is slidably engaged on one side of the drive chamber.

[0015] The beneficial effects of this invention are as follows: This surface coating equipment for waterproof fabric processing involves the fabric body first passing through a feeding roller during the coating process. A steam spray box at one end of the feeding roller is connected to an external steam device via a top steam inlet pipe, spraying the fabric body with high-temperature steam to make the gaps on the fabric surface fluffy and relaxed. During the rotation of the feeding roller, due to the centrifugal force, the needle slides outward to overcome the tension of the slide spring, allowing the piercing needle to extend and perform an orderly piercing process on the surface of the fabric body. Subsequently, the fabric body enters the coating chamber at the bottom, which is filled with waterproof coating. During the coating process, the drive motor controls the drive gear to rotate the gear disc, and the angle of the injection head can be adjusted to insert into the fabric body at different angles. During rotation, an external air pump inflates the air inlet ring and blows air through the air guide pipe to the injection hole on the injection head. Through the negative pressure, the waterproof coating is blown into the pierced fabric body through the feed hole on one side, coating and injecting the waterproof fabric into the interior of the fabric body. After solidification with the surface waterproof fabric, it forms a deep cone, improving the tensile and waterproof effect of the finished fabric. Attached Figure Description

[0019] In use, the fabric body 2 is fed through one end of the main unit 1, following the feeding and winding sequence shown in the diagram, and then discharged through the discharge hole at the other end of the main unit 1. The finished waterproof fabric is wound by the fabric rolling roller 11. During the coating process, the fabric body 2 first passes through the feeding roller 12. A steam spray box 3 at one end of the feeding roller 12 is connected to an external steam device via a top steam inlet pipe 4, spraying the fabric body 2 with high temperature, making the gaps on the fabric surface fluffy and relaxed. During the rotation of the feeding roller 12, due to centrifugal force, the needle slide 33 slides outward, overcoming the tension of the slide spring 34, allowing the piercing needle 32 to extend and perform an orderly piercing process on the surface of the fabric body 2. Subsequently, the fabric body 2 enters the coating chamber 6 at the bottom, which is filled with waterproof coating. During the coating process, the drive motor controls the drive gear, causing the rotating gear disc 27 to rotate, adjusting the angle of the injection head 23, allowing for insertion at different angles. The fabric body 2 is inserted into the fabric body 2. During rotation, an external air pump inflates the air intake ring 28 and blows air through the air guide pipe 21 to the injection hole 29 on the injection head 23. Through negative pressure, the waterproof coating is blown into the fabric body 2 through the feed hole 30 on one side. This can coat and inject the waterproof fabric into the fabric body 2. After solidification with the surface waterproof fabric, it forms a deep cone, improving the tensile and waterproof effect of the finished fabric. After subsequent leveling, the fabric enters the drying mechanism. When passing through the first drying chamber 16 and the second drying chamber 17, the friction roller 43 contacts the fabric and rolls due to the compression of the limit spring 41. The power is transmitted to the rotating rod 37 through the bevel gear set, causing the swing plate 35 to swing to one side. The generated wind force and the impact on the fabric body 2 can make the fabric body 2 dry quickly. Then, the resistance slippage effect causes the return spring 36 to pull, returning the swing plate 35 to its original position. The drying process is repeated.
