Description

Technical Field

[0001] The utility model relates to the field of hot melt adhesive powder processing, in particular to a low-temperature copolyester hot melt adhesive powder processing device. Background Art

[0002] Polyester resin used as hot melt adhesive is a thermoplastic product obtained by esterification of dibasic acid and diol. It is usually made of dimethyl terephthalate, isophthalic acid, ethylene glycol and butanediol.

[0003] The traditional hot melt method of hot melt adhesive powder processing mainly involves manually placing the hot melt adhesive powder in a hot melt pool and then soaking it in warm water. This method is not only labor-intensive and has low processing efficiency, but also the uneven mixing will cause bubbles and impurities in the hot melt adhesive.

[0004] After searching the existing Chinese patent: low-temperature copolyester hot melt adhesive powder processing device (Announcement No.: CN216831689U), including a cylinder and a cylinder cover, the left side of the top of the cylinder cover is fixedly connected with a water injection pipe, the right side of the top of the cylinder cover is fixedly connected with a feed hopper, the rear side of the top of the cylinder is fixedly connected with a drive motor, the output end of the drive motor is fixedly connected with a driving gear, the cylinder cover is rotatably connected with a transmission shaft, the transmission shaft is fixedly sleeved with a driven gear, a filter screen is provided in the cylinder, the transmission shaft passes through the filter screen and extends to the bottom of the cylinder, a plurality of crushing blades and a plurality of stirring rods are provided on the transmission shaft, a scraper is fixedly connected to the other end of the stirring rod, the scraper fits exactly with the inner wall of the cylinder, three fixed rods are fixedly connected to the inner wall of the cylinder, a fixed shaft sleeve is fixedly connected between the three fixed rods, a feed pipe is fixedly connected to the bottom of the cylinder, and a plurality of turns of electric heating wire are provided in the inner wall of the cylinder; this device can crush the hot melt adhesive powder, add water for heating and stirring, and improve the uniformity and efficiency of hot melt adhesive making.

[0005] Although the above patent can crush and stir the materials by setting multiple crushing blades and multiple stirring rods, thereby improving the stirring effect, the disadvantage of this device is that the feed hopper is at the top of the cylinder. When the height of the cylinder is high, it makes the feeding work of the workers very troublesome. They need to use an escalator to feed the materials, which not only wastes time, but also makes it easy to fall during the feeding process, posing a safety risk. At the same time, the filter screen cannot vibrate, and when the materials fall, they are easy to pile up, thereby affecting the filtration efficiency.

[0006] Therefore, it is necessary to invent a low-temperature copolyester hot melt adhesive powder processing device to solve the above problems. Utility Model Content
