[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1 Please see Figures 1 to 6 This utility model provides a technical solution: a hot melt device for bonding PP materials, comprising a base plate 1, an arc-shaped plate 2, and a winding roller 3. A first fixing plate 4, a U-shaped frame 5, a support plate 6, a second fixing plate 7, and a worktable 8 are respectively installed on the top of the base plate 1. A first servo motor 9 is installed behind the first fixing plate 4, and a second servo motor 10 is installed behind the second fixing plate 7. A cavity disk 11 is installed at the output end of the first servo motor 9 and the second servo motor 10. Threaded holes are opened on the outer surface of the cavity disk 11 and inside the arc-shaped plate 2, and bolts 12 are installed inside the threaded holes. A limit block 13 is installed on the inner wall of the arc-shaped plate 2, and a limiter is installed on the top of the limit block 13. Positioning slider 14, positioning block 15 is installed at the end of winding roller 3, strip plate 16 is installed on the inner wall of U-shaped frame 5, return spring 17 is installed on the inner top wall of U-shaped frame 5, lifting frame 18 is installed at one end of return spring 17, pull plate 19 is installed on the top of lifting frame 18, strip slider 20 is installed at the front and back of lifting frame 18, first transmission roller 21 is rotatably connected to the inside of lifting frame 18 through shaft, second transmission roller 22 is rotatably connected to the inside of U-shaped frame 5 through shaft, electric push rod 23 is installed on the inner top wall of support plate 6, cavity heat conduction plate 24 is installed at the movable end of electric push rod 23, and constant temperature heater 25 is installed inside cavity heat conduction plate 24.

[0017] Specifically, the vent on the cavity heat-conducting plate 24 facilitates air circulation within the cavity heat-conducting plate 24, and facilitates heat conduction for the hot melting of the PP material.

[0018] Please see Figures 1 to 4 The top of the cavity heat-conducting plate 24 is provided with a vent, and the position of the cavity heat-conducting plate 24 corresponds to the position of the workbench 8.

[0019] Specifically, the positioning block 15 and the positioning groove on the cavity disk 11 cooperate to facilitate the positioning and installation of the winding roller 3.

[0020] Please see Figures 1 to 4 The cavity disk 11 has a positioning groove on the front that is adapted to the positioning block 15. The end of the positioning block 15 is inserted into the inside of the positioning groove, and the winding roller 3 abuts against the cavity disk 11.

[0021] Specifically, the upper limit groove of the limit block 13 and the positioning block 15 facilitates the limit block 13 to restrict the position of the positioning block 15 and improves the stability of the winding roller 3 installation.

[0022] Please see Figures 1 to 6 The inner wall of the arc plate 2 abuts against the outer surface of the cavity plate 11. One side of the positioning block 15 is provided with a limiting groove that matches the limiting block 13. The end of the limiting block 13 away from the arc plate 2 is inserted into the inside of the limiting groove.

[0023] Specifically, the cooperation between the positioning slider 14 and the positioning groove on the arc plate 2 serves to guide the limiting block 13 and improve the stability of the movement of the limiting block 13.

[0024] Please see Figures 1 to 6 The cavity disk 11 has a positioning groove with the vertical direction as the depth direction and the horizontal direction as the length direction. The end of the positioning slider 14 is located inside the positioning groove, and the positioning slider 14 can slide along the length direction of the positioning groove.

[0025] Specifically, the cooperation between the first drive roller 21 and the second drive roller 22 facilitates the bonding of PP materials; the cooperation between the strip slider 20 and the strip groove on the strip plate 16 guides the first drive roller 21.

[0026] Please see Figures 1 to 5 The positions of the first transmission roller 21 and the second transmission roller 22 are corresponding. One side of the strip plate 16 is provided with a strip groove with the front-back direction as the depth direction and the up-down direction as the length direction. The end of the strip slider 20 is located inside the strip groove, and the strip slider 20 can slide along the length direction of the strip groove.

[0027] In use, the first servo motor 9 drives the cavity disk 11 and the winding roller 3 to rotate, facilitating the release of PP material from the winding roller 3 and allowing the PP material to pass between the first drive roller 21 and the second drive roller 22. Pulling the pull plate 19 upward causes the lifting frame 18 to move the first drive roller 21 upward, causing the return spring 17 to contract and guide the strip slider 20 within the strip groove, thus creating a certain gap between the first drive roller 21 and the second drive roller 22 to facilitate the passage of the PP material between them. Then, the pull plate 19 is released. The pull plate 19, through the elastic tension of the return spring 17 and the weight of the first transmission roller 21, ensures that both the first transmission roller 21 and the second transmission roller 22 abut against the PP material, facilitating the bonding and close contact of the PP material; the constant temperature heater 25 heats the material, and the air vents on the cavity heat-conducting plate 24 facilitate air circulation, which in turn transfers heat through the cavity heat-conducting plate 24; the movable end of the electric push rod 23 extends, causing the cavity heat-conducting plate 24 to move downwards, facilitating the hot pressing of the PP material on the worktable 8, achieving the bonding and heat melting of the PP material; the second servo motor 10 drives the cavity plate 11 and... The winding roller 3 rotates to facilitate the winding of the heat-melted PP material. When the winding roller 3 is fully wound with the heat-melted PP material or when the winding roller 3 is empty of PP material, the operation to disassemble the winding roller 3 is as follows: Tighten bolt 12 to disengage bolt 12 from the threaded holes on the arc plate 2 and the cavity disk 11; then move the arc plate 2 to move the limiting block 13, causing the positioning slider 14 to move, so that the end of the limiting block 13 leaves the limiting groove on the positioning block 15, while the positioning slider 14 slides along the length of the positioning groove; finally, move the winding roller 3 to move the positioning block 15 away from the cavity disk 11. The positioning groove on plate 1 is used to disassemble the winding roller 3. Conversely, when installing the winding roller 3, the winding roller 3 is moved so that the end of the positioning block 15 is inserted into the positioning groove on the cavity plate 11. When the winding roller 3 abuts against the cavity plate 11, the limiting block 13 is aligned with the limiting groove on the positioning block 15. The arc plate 2 is moved so that the end of the limiting block 13 is inserted into the limiting groove. When the arc plate 2 abuts against the cavity plate 11, the bolt 12 is tightened so that the bolt 12 enters the threaded hole on the arc plate 2 and the cavity plate 11, thereby improving the stability of the winding roller 3 installation.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
