Description

Technical Field

[0001] The invention relates to the technical field of lining cloth production, in particular to a high-peeling and washable lining cloth production device and a process thereof. Background Art

[0002] In view of the fact that both the slurry dot coating and the powder dot coating have not solved the problems of glue seepage into thin base fabrics and insufficient peel strength for difficult-to-bond fabrics, the double-dot method has become the main production tool process for adhesive interlinings. The advantages of the slurry dot method and the powder dot method have been combined to develop a slurry dot coating for the bottom layer with high-temperature hot-melt adhesive, and then a relatively low-temperature hot-melt adhesive powder is sprinkled on the slurry dot. Then, the two layers of hot-melt adhesive are put into the drying room together to evaporate the moisture so that the two layers of hot-melt adhesive are fixed on the base fabric. However, the existing powdering technology is to sprinkle the adhesive powder in a direction perpendicular to the lining cloth and downward. Due to the different surface temperatures of the powder dots, the temperature in the middle part is higher than that on the two sides, resulting in different adhesion between the powder dot surface and the adhesive powder, which makes the wrapping of the adhesive powder and the powder dot surface worse.

[0003] A Chinese invention patent with application publication number CN108160418A discloses a lining cloth production and processing equipment, including a frame, a powder storage chamber, a powder spreading device, a first conveying mechanism, a second conveying mechanism and a powder suction device. An auxiliary powder storage box is provided in the powder spreading device, a feeding flower roller assembly is provided in the auxiliary powder storage box, a second discharge hopper is provided at the bottom of the auxiliary powder storage box, a first conveying mechanism is provided below the powder spreading device, the first conveying mechanism cooperates with the second conveying mechanism, and a powder suction device is provided on the second conveying mechanism. The weight of the powder material in the auxiliary powder storage box is controlled by the feeding flower roller assembly, and uniform powder spreading is achieved in combination with a vibrating screen. The electromagnetic coil drive assembly cooperates with the drive soft strips arranged at intervals to achieve regular vibration of the second grid conveyor belt. With three blows and two suctions, excess powder particles can be recovered in time.

[0004] However, the inventors found that the device has the following problems: the device adopts the powder dot method, so the device is not suitable for certain heat-sensitive high-elastic base fabrics, and the produced lining fabric has low peeling strength and average washability.

[0031] It is worth mentioning here that the heating roller 41 preheats the base fabric passing through, one end of the engraving roller 9 is connected to the extruder, and the other end is connected to the hot melt adhesive supply device. After the hot melt adhesive enters the extrusion channel 42, the extruder squeezes the inside of the engraving roller 9 to form a number of inverted spherical crown-shaped hot melt adhesives on the surface of the engraving roller 9, and then the hot melt adhesive is bonded to the base fabric by contacting with the heated base fabric.

[0032] like Figure 5 As shown, the powder sprinkling channel 10 is U-shaped, the powder suction channel 11 is arranged at the confluence of the powder sprinkling channels 10 on both sides, the bottom of the powder sprinkling channel 10 is in contact with the lining cloth, a plurality of powder sprinkling holes 51 are provided at the bottom of the powder sprinkling channel 10, the powder sprinkling holes 51 on both sides are inclined toward the powder suction channel 11, a powder inlet 52 is provided on the powder sprinkling channel 10, a suction port 53 is provided above the powder suction channel 11, and a baffle 54 is further provided at the lower end of the powder sprinkling channel 11, and the baffle 54 is inclined outward.
