[0007] Furthermore, two annular grooves are symmetrically opened on the inner wall of the hot melt chamber near the two ports, and the hot melt assembly also includes two partition nets, the partition nets are provided with a plurality of through holes, and the partition nets are embedded in the annular grooves.

[0013] 2.

[0014] 3. By matching the shape of the arc groove with the inner wall of the hot melt chamber, the plastic particles will not fall into the material tube during the hot melt process, causing the stirring shovel to be unable to stir. At the same time, it can prevent the sealing plug from adhering to the material tube after the plastic particles are hot melted, causing the material tube to be unable to be opened;

[0015] 4. By adding a partition net and a resistance wire, the resistance wire can be separated from the plastic particles to ensure a balanced heating effect. The annular plate at the edge of the partition net can prevent the plastic particles from flowing through the through hole to the resistance wire after hot melting. That is, while improving the hot melting efficiency of the hot melting equipment, it prevents the hot melted plastic from affecting the hot melting effect of the resistance wire.

[0034] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0035] See also Figure 1-6 The utility model provides a technical solution: a high-stability modified plastic hot-melt device, comprising a base 1 and a hot-melt component 2, wherein the hot-melt component 2 is fixed on the base 1.

[0036] The hot melt assembly 2 includes a hot melt chamber 21 , two sealing plugs 22 , two end covers 23 , a stirring device 24 , two partition nets 25 and two resistance wires 26 .

[0037] Two annular grooves 210 are symmetrically provided on the inner wall of the hot melt chamber 21 near the two ports, and two material pipes 211 are symmetrically provided on the side of the hot melt chamber 21. The interior of the material pipe 211 is connected to the interior of the hot melt chamber 21, and two through rods 212 are symmetrically fixed on the end surface of the material pipe 211 away from the hot melt chamber 21.

[0038] The sealing plug 22 includes a widened portion 221 and an embedded portion 222. The widened portion 221 is symmetrically provided with two through holes 2210. The embedded portion 222 is provided with an arc-shaped groove 2220 at one end away from the widened portion 221. When the widened portion 221 is covered on the material tube 211 in a manner in which the through holes 2210 and the penetrating rod 212 are embedded, the embedded portion 222 is inserted into the material tube 211, and the arc-shaped groove 2220 is matched with the shape of the inner wall of the hot melt chamber 21.

[0039] The end cover 23 is fixed to the open end of the hot melt chamber 21 .

[0040] The stirring device 24 is arranged inside the hot melt chamber 21, and includes a rotating shaft 241, multiple connecting rods 242, and multiple stirring shovels 243. The rotating shaft 241 is rotatably connected to the two end covers 23. The multiple connecting rods 242 are fixed on the rotating shaft 241 and are circumferentially arranged along the side of the rotating shaft 241. The stirring shovel 243 is fixed to the end of the connecting rod 242 away from the rotating shaft 241. The stirring shovel 243 is arranged in an arc shape and fits against the inner wall of the hot melt chamber 21. Smooth blades 2431 are provided at both ends of the stirring shovel 243.

[0041] A plurality of through holes 250 are formed on the partition net 25 . The partition net 25 is embedded in the annular groove 210 . An annular plate 251 is formed at the edge of the partition net 25 .

[0042] The two resistance wires 26 are respectively disposed on opposite end surfaces of the two end covers 23 .

[0043] It can be understood that by rotating the rotating shaft 241 with an external drive, the connecting rod 242 and the stirring shovel 243 can be driven to rotate through the rotating shaft 241. In this way, when the plastic particles are hot-melted inside the hot melt bin 21, the stirring shovel 243 can continuously stir the plastic particles, so that the plastic particles are heated more evenly inside the hot melt bin 21, thereby improving the hot-melting efficiency of the plastic particles.

[0044] By adding smooth blades 2431 at both ends of the stirring shovel 243, the stirring shovel 243 can shovel off the plastic adhering to the inner wall of the hot melt bin 21 when rotating, so as to prevent the plastic from adhering to the inner wall of the hot melt bin 21 after hot melting to form wall scale, thereby preventing it from affecting the efficiency of subsequent hot melt plastic particles.

[0045] By matching the shape of the arc groove 2220 with the inner wall of the hot melt chamber 21, the plastic particles will not fall into the material tube 211 during the hot melt process, causing the stirring shovel 243 to be unable to stir, and at the same time, it can prevent the plastic particles from adhering to the sealing plug 22 on the material tube 211 after hot melting, causing the material tube 211 to be unable to open.

[0046] By adding a partition net 25 and a resistance wire 26, the resistance wire 26 can be separated from the plastic particles to ensure a balanced heating effect. The annular plate 251 at the edge of the partition net 25 can prevent the plastic particles from flowing through the through hole 250 to the resistance wire 26 after hot melting. That is, while improving the hot melting efficiency of the hot melting equipment, it prevents the hot-melted plastic from affecting the hot melting effect of the resistance wire 26.

[0047] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
