For example, in China, the patent announcement number is CN107934619B, a fully automatic hot melt adhesive laminating machine. When hot melt laminating is rolled, the fabric passes through the first rotating composite roller, the fabric expander, the second rotating composite roller, the second support roller, and the second composite roller. The first and second silicone strips are bonded together by a pair of rollers, a third support roller, a second tension controller, a first silicone strip opening roller, a pair of glue rollers and a second silicone strip opening roller to reach a composite pair of rollers. After the second fabric is glued, it is composited with the first fabric under the action of the composite pair of rollers. The composited fabrics are cooled by the upper water-cooled roller in turn to achieve the composite of the fabrics. However, the prior art mainly utilizes the pair of glue rollers for gluing, but it cannot effectively reflect the effects of pressurization and rapid glue output. The glue rollers may be uneven and insufficient when in use, and the use effect needs to be improved. Therefore, it is necessary to design an improved fully automatic composite machine for hot melt adhesive production. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1-Figure 5The utility model provides a technical solution for a fully automatic compound machine for producing hot melt adhesive, comprising an installation frame 1, a rotating compound roller 2, a glue roller 3, and a driving mechanism arranged on one side of the installation frame 1 for driving the rotating compound roller 2 and the glue roller 3 to rotate. The driving mechanism is the principle of driving the roller to rotate by a motor in the prior art, so it is not described in detail here. A pressurized hot melt adhesive box 4 is installed on one side of the installation frame 1, a glue cavity 32 is opened in the middle of the glue roller 3, and a plurality of glue outlet holes 31 connected to the glue cavity 32 are arranged on the surface of the glue roller 3, an end of the glue roller 3 away from the driving mechanism is connected with an L-shaped connecting pipe 5, and the glue cavity 32 is connected to the pressurized hot melt adhesive box 4 through the L-shaped connecting pipe 5, the installation frame 1 is installed on one side of the installation frame 1, and a spiral blade rod 6 is adapted to rotate on the inner side of the L-shaped connecting pipe 5, and the axial end of the spiral blade rod 6 passes through one side of the L-shaped connecting pipe 5 and is connected to the shaft of an external pressurizing motor 61, and the pressurizing motor 61 drives the spiral blade rod 6 to rotate, so the spiral blade rod 6 The rotation can improve the efficiency and effect of conveying the hot melt adhesive from the pressurized hot melt adhesive box 4 into the adhesive chamber 32, wherein the pressurized hot melt adhesive box 4 includes a box body 40, a feed port 41 and a discharge port 42 arranged on the upper and lower sides of the box body 40, and a heating plate 47 installed at the bottom of the inner side of the box body 40, and the hot melt adhesive particles are heated and melted by the heating plate 47. A lifting and lowering plate 46 is horizontally arranged on the inner side of the box body 40, and a first electric push rod 461 is vertically installed on the top of the box body 40. The telescopic end of the first electric push rod 461 is It is locked and connected with the lifting and lowering pressure plate 46, and the bottom end of the discharge port 42 is communicated with the top of the L-shaped connecting tube 5. Therefore, the hot-melt adhesive is squeezed downward by lifting and lowering the lifting and lowering pressure plate 46, and the L-shaped connecting tube 5 is squeezed and transported downward, so that the hot-melt adhesive can enter the L-shaped connecting tube 5 more tightly and fully, and under the continuous threaded conveying of the spiral blade rod 6, the conveying of the hot-melt adhesive is more efficient, and a control valve 51 is installed on the upper side of the L-shaped connecting tube 5, and the control valve 51 is opened and closed to control the flow of the hot-melt adhesive in the L-shaped connecting tube 5.

[0023] A further design is that a plurality of rotating cylinders 45 are installed at the bottom of the lifting and pressure plate 46, and a stirring blade 451 is installed on the outside of each rotating cylinder 45, and a plurality of polygonal rotating rods 43 are vertically arranged on the inside of the box body 40, and a crushing blade 431 is installed at the bottom of the polygonal rotating rod 43. A rotating motor 44 for driving the polygonal rotating rod 43 to rotate is installed on the top of the box body 40. Each of the polygonal rotating rods 43 rotates and passes through the middle of the lifting and pressure plate 46, and is set through the middle of each rotating cylinder 45. The inner cavity of the rotating cylinder 45 is adapted to the surface of the polygonal rotating rod 43. Through this design, the rotating motor 44 can drive the polygonal rotating rod 43 and the crushing blade 431 to crush and stir the internal hot melt adhesive particles, and simultaneously let the polygon The rotating rod 43 drives the stirring blade 451 on the outside of the rotating cylinder 45 to rotate, so as to crush, mix and stir the hot melt adhesive. The crushing blade 431 breaks the larger hot melt adhesive blocks into smaller particles when crushing, which can increase the surface area of ​​the hot melt adhesive and promote the subsequent mixing and heating process. When the lifting and lowering pressure plate 46 rises and falls, it can drive the rotating cylinder 45 and the stirring blade 451 to move up and down synchronously, so as to increase the range of upper and lower mixing and stirring while pressurizing the hot melt adhesive for transportation. The design of the stirring blade 451 allows the hot melt adhesive to circulate inside the box, which helps to evenly mix the hot melt adhesive and prevent solidification or degradation caused by uneven temperature. At the same time, it can also accelerate the transfer of heat to ensure that the hot melt adhesive can be evenly heated and improve the transportation effect of the hot melt adhesive.

[0024] The inner cross section of the polygonal rotating rod 43 is a rectangle, so when the polygonal rotating rod 43 rotates, it can synchronously drive the rotating cylinder 45 that is adapted to rotate. Of course, other polygonal shapes such as triangles, hexagons, etc. can also be used.

[0025] In addition, second electric push rods 71 ​​are vertically installed on both sides of the mounting frame 1, and pressure rollers 7 are rotatably installed at the telescopic ends of the two second electric push rods 71. The pressure rollers 7 roll between the rotating composite roller 2 and the glue roller 3. The lifting and lowering of the second electric push rods 71 ​​drive the pressure rollers 7 to better roll the cloth, so that the cloth is tightly attached to the rotating composite roller 2 and the glue roller 3.

[0026] Specifically, when in use, the hot melt adhesive particles are thrown into the heating plate 47 inside the box body 40 from the feed port 41, and the polygonal rotating rod 43 and the crushing blade 431 are driven to rotate by the rotating motor 44 to fully crush the hot melt adhesive particles into fine particles, so as to facilitate the hot melting of the hot melt adhesive, and the polygonal rotating rod 43 synchronously drives the rotating cylinder 45 and the stirring blade 451 to stir the hot melt adhesive, and the first electric push rod 461 is extended and retracted up and down, so that the lifting and pressing plate 46 pushes and pulls the rotating stirring blade 451 to rotate and stir in an upper and lower range, so that the hot melt adhesive is heated more evenly, and when the lifting and pressing plate 46 moves downward, it can generate an extrusion force, so that the hot melt adhesive is more tightly and fully squeezed into the discharge port 42, and enters the glue cavity 32 and the glue outlet hole 31 of the glue roller 3 through the L-shaped connecting tube 5. During this period, after the pressurizing motor 61 drives the spiral blade rod 6 to rotate, it can better improve the fluidity and conveying efficiency of the hot melt adhesive in the L-shaped connecting tube 5, so that the glue outlet hole 31 can be more uniform and sufficient.
