[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a coating spraying device for wear-resistant fabrics.

[0019] Example 1: Combination Figures 1 to 4 As shown, the present invention provides a coating spraying device for wear-resistant fabric, including a fabric tensioning and delivery mechanism 100, a hot air blower 200 installed on the fabric tensioning and delivery mechanism 100, and a spraying mechanism 300 installed on the fabric tensioning and delivery mechanism 100. The hot air blower 200 is used to quickly dry the fabric after the coating is applied, and the spraying mechanism 300 is used to spray the fabric at right angles and reduce the interference of ambient airflow on the sprayed coating.

[0020] The fabric tensioning and delivery mechanism 100 includes a load-bearing housing 110, multiple pressure rollers 150, and multiple anti-slip sleeves 1501. Two tensioning shafts 140 are movably installed inside the load-bearing housing 110. A slide rod 1104 is fixedly installed at the inner end of the tensioning shaft 140. A lever arm 1105 is movably installed at the outer end of the slide rod 1104. An end plate 1106 is movably installed at the other end of the lever arm 1105. Two sets of clamps 1101 are fixedly installed at the bottom of the load-bearing housing 110. Hydraulic components 1102 are fixedly installed inside the two sets of clamps 1101. The end plate 1106 is fixedly installed on the hydraulic components 1102. The interior of the load-bearing housing 110 is provided with a slide rail, and a compression spring 1103 is provided in the middle of the slide rail. The two ends of the compression spring 1103 are respectively pressed on two tensioning shafts 140. Two symmetrically distributed rectangular plate segments are fixedly installed on the bottom of the inner side of the load-bearing housing 110, and two slots are provided in the rectangular plate segments. Two pressure rollers 150 are respectively movably installed at the outer ends of two tensioning shafts 140; The spraying mechanism 300 includes two guide rods 340 installed inside the load-bearing housing 110. One guide rod 340 has an adjusting component 3102 installed at its outer end, and the other guide rod 340 has a limiting component 3201 installed at its outer end. The adjusting component 3102 has a hexagonal threaded sleeve 3101 on its outer side, and a first beam plate 310 is installed on its outer side. The limiting component 3201 has a second beam plate 320 on its outer side. A spray hood 330 is fixedly installed between the first beam plate 310 and the second beam plate 320.

[0021] In use, an external drive device drives the transmission belt 170, which in turn drives three pulleys 160 to rotate. At this time, three auxiliary shafts 130 installed in the three pulleys 160 provide active delivery kinetic energy to the fabric. A pulley 160 movably installed outside one of the tension shafts 140 can provide stabilization and guidance for the transmission belt 170, avoiding interference with the extension and retraction of the tension shaft 140 during transmission. After the hydraulic components 1102 are in operation, they will provide extension kinetic energy to the two tensioning shafts 140. As the two tensioning shafts 140 extend outward, the two pressure rollers 150 and the two anti-slip sleeves 1501 installed on the two tensioning shafts 140 will effectively tension and straighten the part of the fabric to be printed.

[0022] Example 2: Combination Figures 2 to 4As shown, based on Embodiment 1, two symmetrically distributed load-bearing outer frames 120 are fixedly installed on the outside of the load-bearing housing 110. Three auxiliary shafts 130 are movably installed inside the two load-bearing outer frames 120. Pulleys 160 are fixedly installed on the outside of the auxiliary shafts 130, and there are four pulleys 160. Three pulleys 160 are respectively installed on the three auxiliary shafts 130, and the other pulley 160 is movably installed on one of the tensioning shafts 140. The four pulleys 160 are connected to a drive belt 170.

[0023] Preferably, the transmission belt 170 is powered by an external drive device. The fabric is delivered upward from an auxiliary shaft 130 at the bottom until it passes through two tension shafts 140 and the remaining two auxiliary shafts 130 in sequence, and is delivered laterally outward. The part of the fabric between the two tension shafts 140 is stretched and straightened outward by two sets of pressure rollers 150 and anti-slip sleeves 1501. The spray hood 330 with reduced spacing will quickly spray the paint onto the leveled outer surface of the fabric.

[0024] Example 3: Combination Figure 3 and Figure 4 As shown, in the above embodiment, the adjusting component 3102 is composed of a screw and a main sleeve, the limiting component 3201 is composed of a plug rod and a secondary sleeve, and a spring 3202 is provided on the outside of the plug rod; The outer end of the guide rod 340 is threaded with a bolt 3501, and a washer 350 is provided on the outside of the bolt 3501.

[0025] Preferably, both the first beam plate 310 and the second beam plate 320 have internal grooves, and one end of the spring 3202 is fixedly installed on the inner wall of the internal groove of the second beam plate 320. The two gaskets 350 are respectively adapted to fit the outer surfaces of the first beam plate 310 and the second beam plate 320 to provide anti-detachment protection for the two guide rods 340. Adjusting the hexagonal threaded sleeve 3101 with a wrench causes the tensioning assembly 3102 to drive one of the tensioning shafts 140 to move laterally along the inner groove of the first beam plate 310. This process can adjust the distance between the spray hood 330 and the tensioning shaft 140.

[0026] The working principle and usage process of this utility model are as follows: two plate segments inside the load-bearing housing 110 are fixedly installed on a machine tool or workbench using multiple expansion bolts. Then, multiple pulleys 160 are connected by a transmission belt 170, and an external drive device is used to power the transmission belt 170. As the transmission belt 170 is driven, the wear-resistant fabric that is pressed on the outer surfaces of the four sets of pressure rollers 150 and the four sets of anti-slip sleeves 1501 is actively delivered to the gap inside the spray hood 330. According to the tension requirements of the two sides of the wear-resistant fabric, the hydraulic component 1102 is controlled by the cloud until the hydraulic rod inside the hydraulic component 1102 retracts inward and cooperates with the end plate 1106 to stretch the two lever arms 1105 and the two slide rods 1104 outward toward the load-bearing housing 110. Finally, the two tensioning shafts 140 will drive two sets of pressure rollers 150 and anti-slip sleeves 1501 to expand outward, and the wear-resistant fabric that is pressed on the outer surfaces of the two sets of pressure rollers 150 and anti-slip sleeves 1501 can be effectively straightened and tensioned. At this time, the tensioned part of the wear-resistant fabric is matched and aligned with the center position inside the spray hood 330. As the wear-resistant fabric is delivered along the outer surfaces of multiple sets of pressure rollers 150 and multiple sets of anti-slip sleeves 1501, the coating transferred by the spray hood 330 is sprayed directly onto the stretched and straightened outer surface of the wear-resistant fabric in an atomized state. After being sprayed with coating, the wear-resistant fabric continues to be delivered upward and passes through the air vent at the top of the hot air blower 200. The airflow released upward from the air vent at the top of the hot air blower 200 will quickly dry the coating on the fabric.
