Description

Technical Field

[0001] The invention relates to the technical field of PVC tarpaulin, in particular to a PVC tarpaulin and a production process and equipment thereof. Background Art

[0002] PVC tarpaulin is a tarpaulin material with many excellent properties. It is made of high-strength polyester canvas as the base fabric, coated with polyvinyl chloride (PVC) paste resin, and added with speed increaser (synthetic plant ester), mildew inhibitor, anti-aging agent, antistatic agent and other chemical additives, and plasticized at high temperature. PVC tarpaulin plays an important role in various fields with its excellent performance and wide application. PVC tarpaulin production equipment covers all aspects from raw material preparation to product delivery. Through precise weighing, mixing, extrusion, processing, surface treatment, cutting, sewing, quality inspection and packaging, it ensures that the produced PVC tarpaulin has excellent performance and quality. At the same time, with the continuous development and innovation of technology, production equipment is also constantly updated to improve production efficiency and product quality.

[0003] However, the existing PVC tarpaulin production equipment has some shortcomings in the production process, which may affect the quality and production efficiency of the product. Although the PVC tarpaulin itself is wear-resistant, its surface may still be worn when it comes into contact with sharp or rough objects for a long time. Especially in high-wear areas, such as areas that often need to be folded, unfolded or subjected to mechanical friction, its wear resistance may be affected. Although the surface of the PVC tarpaulin is tough, it is still easily scratched by sharp objects such as blades and scissors. Such scratches will not only affect the appearance of the tarpaulin, but may also destroy its waterproof performance. In actual applications, if the construction foundation is uneven or there are sharp objects, the PVC tarpaulin may be subjected to unnecessary wear or scratches during the laying process. Therefore, pre-construction preparation and ground treatment are essential to maintain the wear resistance of the PVC tarpaulin. Summary of the invention

The plain weave structure presented on the surface of the convex strips and the grooves between the convex strips can form tiny channels or diversion structures. When liquid such as water contacts such a fabric, the convex strips and grooves may guide the water flow, making it easier for the water flow to flow along the convex strips, thereby promoting drainage.

[0044] First, the first motor 29 is started to rotate. The rotation of the first motor 29 will drive the second rotating shaft 27 to rotate. The rotation of the second rotating shaft 27 will drive the disc 26 to rotate. The rotation of the disc 26 will drive the second protruding block 25 to rotate. The rotation of the second protruding block 25 will drive the first protruding block 24 to rotate. The rotation of the first protruding block 24 will drive the first sleeve 23 to rotate. The first protruding block 24 and the second protruding block 25 are both made of elastic metal spring steel materials with strong deformation ability. The rotation of the first sleeve 23 will drive the first rotating shaft 22 to rotate. The rotation of the first rotating shaft 22 will drive the winding roller 21 to rotate. The second protruding block 25 is driven to rotate by the first motor 29. The rotation of the second protruding block 25 will drive the first protruding block 24 to rotate. When the body 1 is tightened, the rotation of the first protruding block 24 cannot be driven to rotate. At this time, the second protruding block 25 rotates and encounters the first protruding block 24, which will deform and jump. Such an arrangement can keep the body 1 in a straight state at all times.

[0045] At this time, the second motor 31 is started to rotate. The rotation of the second motor 31 will drive the third rotating shaft 32 to rotate.

The rotation of the connecting block 34 will drive the rotating pin 35 to rotate. The rotation of the rotating pin 35 will drive the second rotating block 36 to rotate. One circle of the third rotating shaft 33 will drive the second rotating block 36 to rotate a quarter circle. In this way, the second rotating block 36 intermittently rotates a quarter circle. The rotation of the second rotating block 36 will drive the first rotating rod 38 to rotate. The rotation of the first rotating rod 38 will drive the first spur gear 310 to rotate. The rotation of the first spur gear 310 will drive the second spur gear 311 to rotate. The diameter of the first spur gear 310 is much larger than that of the second spur gear 311. 1, so that the first spur gear 310 rotates a quarter of a circle and the second spur gear 311 can rotate more circles, the rotation of the second spur gear 311 will drive the second rotating rod 312 to rotate, the rotation of the second rotating rod 312 will drive the transmission roller 313 to rotate, the rotation of the transmission roller 313 will drive the conveyor belt 314 to rotate, the second spur gear 311 rotates more circles to drive the conveyor belt 314 to move a longer distance, the rotation of the conveyor belt 314 will drive the main body 1 to move intermittently for a distance, the distance of the intermittent movement of the main body 1 is just the length of the first pressing plate 47, the length of the first pressing plate 47 is the same as the length of the second pressing plate 52, and the set structure can drive the main body 1 to move intermittently for a distance, which can facilitate the subsequent production and processing of the PVC tarpaulin.

[0046] When the main body 1 moves, the first pressure plate 47 and the second pressure plate 52 are lifted up and away from the main body 1. When the main body 1 stops intermittent movement, a pair of first pressure plates 47 and another pair of second pressure plates 52 will cover the upper and lower surfaces thereof, and the rotation of the third rotating shaft 32 will drive the cam 41 to rotate, and the rotation of the cam 41 will drive the first baffle plate 42 to move toward one end, and the movement of the first baffle plate 42 toward one end will drive the first connecting rod 43 to move toward one end, and the movement of the first connecting rod 43 toward one end will drive the second connecting rod 44 to move toward one end, and the movement of the second connecting rod 44 toward one end will drive the arc block 45 to move toward one end, and the movement of the arc block 45 toward one end will drive the tilting block 46 to move outward, and the outward movement of the tilting block 46 will drive the first pressure plate 47 to move outward, and the outward movement of the first pressure plate 47 will drive the sliding rod 48 to move upward, and the upward movement of the sliding rod 48 will drive the second baffle plate 410 to move upward , the second baffle 410 moves upward to compress the spring 411, and when the first pressing plate 47 covers the upper end of the main body 1, the heating plate 415 inside it can heat the surface of the main body 1. The lower end of the first pressing plate 47 is a plurality of semi-arc strip structures. The first pressing plate 47 heated by the heating plate 415 covers the surface of the main body 1 and molds its surface into the same shape, thereby completing the processing of the anti-slip layer 14 on the surface of the main body 1. The structure set can ensure that the first pressing plate 47 and the second pressing plate 52 are lifted away from the main body 1 when the main body 1 moves. When the main body 1 stops intermittent movement, a pair of first pressing plates 47 and another pair of second pressing plates 52 will cover its upper and lower surfaces, and the first pressing plate 47 heated by the heating plate 415 covers the surface of the main body 1 and molds its surface into the same shape, thereby completing the processing of the anti-slip layer 14 on the surface of the main body 1.

[0047] At this time, cooling water is introduced into the water inlet pipe 51, and the cooling water introduced into the water inlet pipe 51 will enter the second sleeve 49, and the cooling water will pass through the second hollow groove 412 in the second sleeve 49 and flow into the second cavity 54 in the second pressing plate 52, and the cooling water in the second cavity 54 can cool the formed tarpaulin, and the cooling water in the second cavity 54 will flow out through the connecting pipe 53, and the cooling water flowing out of the connecting pipe 53 will pass through the arc block 45 and the second connecting rod 44 and enter the chute 417, and the cooling water in the chute 417 will be discharged from the equipment through the connecting pipe 53, and the first pressing plate 47 heated by the heating plate 415 will be quickly cooled and formed when it covers the surface of the main body 1, moves to the lower end of the second pressing plate 52 and engages with the second groove 55, and the structure is set, and the first pressing plate 47 heated by the heating plate 415 will be quickly cooled and formed when it covers the surface of the main body 1, moves to the lower end of the second pressing plate 52 and engages with the second groove 55, thereby improving the production efficiency of the product.
