Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive lining production, in particular to a double - point coating and powdering device for hot melt adhesive lining. Background Technique

[0002] For the lining coating process, it has evolved from powder dots, single slurry dots to double dots. The so - called double dots means that on the lining base fabric, slurry dots are first coated on the base fabric by the method of scraping and screen coating with a scraper, and then a certain particle - size hot melt adhesive powder is sprinkled on the slurry dots through a powder - sprinkling device. Then, through a blowing and suction system, the excess powder between the dots and the powder that is not firmly adhered on the slurry dots is sucked away. When applying the powder to the lining through the powdering mechanism, after the powder - sprinkling roller of the powdering mechanism rotates, the powder drops from the powdering mechanism. The powder accumulates in the powdering mechanism. When there is a large amount of powder in the powdering mechanism, the powder solidifies due to static force, and the powder cannot drop from the powdering mechanism after the powder - sprinkling roller rotates.

[0003] Chinese Patent CN220346392U discloses a double - point coating and powdering device for hot melt adhesive lining. The powder - sprinkling roller is rotatably connected to the powder - feeding funnel. The powder - sprinkling roller is fixedly connected to the input shaft. The elastic block is fixedly connected to the powder - feeding funnel and is in contact with the powder - sprinkling roller. There is a gap between the powder - sprinkling roller and the powder - feeding funnel. The vibration motor is fixedly connected to the powder - feeding funnel, and the blowing mechanism is fixedly connected to the powder - feeding funnel. The input shaft is drivingly connected to the blowing mechanism. A through - hole is opened on the powder - feeding funnel, and the through - hole communicates with the blowing mechanism. A collecting mechanism for collecting powder is fixedly connected to the powder - feeding funnel. After the input shaft rotates, it drives the powder - sprinkling roller to rotate. After the powder - sprinkling roller rotates, the powder drops from the gap. After the vibration motor is started, it generates vibration, and the vibration destroys the static balance of the powder, causing the powder to drop from the gap. The powder will not have relative sliding with the powder - sprinkling roller, improving the powder - sprinkling effect of the powder - sprinkling roller. However, when using the blowing method for powdering, the powder is easily blown in all directions, causing environmental pollution and more waste.

[0004] Therefore, those skilled in the art have provided a double - point coating and powdering device for hot melt adhesive lining to solve the problems raised in the above - mentioned background technique. Content of the Utility Model

When powdering, turn on the servo motor 707 to drive the cam 708 to rotate. The cam 708 continuously squeezes the hemispherical block 706. The hemispherical block 706 drives the mounting plate 705 to move. The mounting plate 705 drives the reset rod 704 to move. The reset rod 704 drives the fixing plate 703 to squeeze the reset spring 702. When the cam 708 separates from the hemispherical block 706, the reset spring 702 rebounds, causing the mounting plate 705 to reciprocate. The mounting plate 705 drives the powder feeding hopper 401 to reciprocate, so that the adhesive powder continuously falls from the discharge mesh plate 405 and is scattered on the lining cloth body 5. Turn on the stepper motor 403 to drive the stirring rod 404 to rotate, which can further prevent the adhesive powder from accumulating.

[0040] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby.
