[0030] Working principle: before using the PUR hot melt electronic glue heating device, the overall situation of the device needs to be checked to determine whether it can work normally, according to Figure 1 -Figure 6As shown, the end cap 201 is sealed between the body 102 of the glue melting machine by adjusting the assembly 3 operated by the staff, and then the staff starts the heating structure inside the body 102 of the glue melting machine to heat the glue block inside the melting tank 103. At this time, the staff starts the servo motor 212 to drive the rotation of the rotating shaft 202, and the rotation of the rotating shaft 202 drives the rotation of the stirring blade 203, and the rotation of the stirring blade 203 stirs the PUR hot melt adhesive inside the melting tank 103, and the rotation of the rotating shaft 202 drives the upward transmission of the spiral blade 204 to the PUR hot melt adhesive, thereby improving the stirring efficiency and mixing uniformity of the PUR hot melt adhesive. When the staff operates the controller to make the servo motor 212 rotate at low speed, the rotation of the rotating shaft 202 drives the rotation of the fixed box 205 at this time, and the rotation of the fixed box 205 drives the rotation of the connecting rod 208. At this time, the connecting rod 208 is thrown out of the fixed box 205 by the action of centrifugal force, and the sliding sleeve 207 slides outside the fixed rod 206 at this time. At this time, the first extension spring 211 is stretched, and at this time the staff controls the heating wire 210 to run, and at this time the heating wire 210 heats the scraper 209, so that the rotating scraper 209 stirs the PUR hot melt adhesive inside the melting tank 103 again.

At this time, the first extension spring 211 pulls the sliding sleeve 207 to reset quickly, and then the connecting rod 208 is quickly retracted into the fixed box 205. At this time, the protruding block 214 is inserted between the grooves 216, so that the connecting rod 208 can be retracted and fixed when the scraper 209 is not stirring, thereby avoiding the influence of the scraper 209 always in the expanded state on the subsequent cleaning and feeding effect of the staff, further reducing the phenomenon of staff arm burns, improving the efficiency of daily use and maintenance of the device, and bringing convenience to the staff during use. Through the design of the high-temperature-resistant sealing ring 217,Thus, the sealing between the end cover 201 and the glue melting machine body 102 is better.
[0031] The staff drives the forward and reverse motor 304 to drive the rotation of the screw rod 303, the rotation of the screw rod 303 drives the up and down movement of the first moving plate 305, the movement of the first moving plate 305 drives the movement of the end cover 201, and the movement of the end cover 201 drives the movement of the second moving plate 308. At this time, one end of the second moving plate 308 is located outside the limiting rod 307 and slides, so that the height of the stirring mechanism 2 can be quickly adjusted, and the staff can conveniently add materials and maintain the inside of the glue melting machine body 102, thereby greatly improving the use efficiency of the device, and the traditional manual method of taking the end cover 201 is more convenient, which brings convenience to the staff during use.
[0032] The base 1, the operation table 101, the glue melting machine body 102 and the glue tank 103 are prior art, and the publication number CN208757849U discloses a new type of PUR hot melt glue melting machine. The device used in the prior art will not be described here.
