[0023] In the prior art, the silicone products are stirred and mixed in a stirring box and then transported to a hot-melt mechanism for hot-melting.

[0024] The inventor of the utility model found that the working process is to stir the silicone before hot-melt treatment. When the silicone material is hard, it may not be stirred, and it is not convenient to hot-melt treatment while stirring, which is not convenient for improving the efficiency of hot-melt treatment.

[0025] like Figure 1-4 As shown, a hot melt extrusion device for silicone products includes: a base 1, a tank body 3 is fixedly connected to the top of the base 1 through a support rod 2, a heating chamber 4 is fixedly connected to the inner surface of the tank body 3, a rotating assembly 5 is arranged on the inner surface of the heating chamber 4, the rotating assembly 5 includes a shaft sleeve 501, the shaft sleeve 501 penetrates and is fixedly connected to the top of the tank body 3, a rotating shaft 502 is rotatably connected to the inner surface of the shaft sleeve 501, a driving assembly 6 is arranged above the rotating shaft 502, and the driving assembly 6 includes a motor base 601, the motor base 601 is fixedly connected to the top of the tank body 3, and a motor 60 is fixedly connected to the left side of the motor base 601. 2. The output end of the motor 602 is fixedly connected to the rotating shaft 502 through a coupling. A rotating bar 503 is fixedly connected below the rotating shaft 502. A stirring assembly 7 is arranged below the rotating bar 503. A feeding assembly 8 is arranged on the left side of the tank body 3. A heating device 9 is arranged on the front of the tank body 3. The heating device 9 specifically includes a heater and an electric heating wire connected to the back thereof. The electric heating wire is wound around the outer surface of the heating bin 4. The heating bin 4 is heated by the electric heating wire to achieve a hot-melt effect on the silicone. A discharge valve 10 is fixedly connected below the tank body 3. The discharge valve 10 is used to discharge the silicone after the hot-melt treatment.

[0026] like Figure 1-4 As shown, specifically, after the silicone product raw materials are placed in the heating chamber 4, the heating device 9 is started to heat the heating chamber 4 to melt the silicone product raw materials. At this time, the motor 602 is started to drive the rotating shaft 502 to rotate, so that the rotating bar 503 rotates, and the stirring component 7 under the rotating bar 503 will stir the silicone product raw materials in the heating chamber 4 as the rotating bar 503 rotates, so that the silicone product raw materials are stirred while being hot-melt treated, thereby achieving an efficient hot-melt treatment effect.

[0027] like Figure 1-4 As shown, the stirring assembly 7 includes a rotating rod 701, which passes through and is rotatably connected to the bottom of the rotating bar 503, and stirring rods 702 are fixedly connected to the left and right sides of the rotating rod 701. A support sleeve 703 is movably sleeved on the outer surface of the rotating rod 701, and the support sleeve 703 is fixedly connected to the bottom of the rotating bar 503. A connecting assembly 12 is arranged above the rotating rod 701, and the connecting assembly 12 includes a gear 121, which is fixedly connected to the top of the rotating rod 701, and an annular tooth 122 is meshed on the left side of the gear 121, and the annular tooth 122 is fixedly connected to the outer surface of the sleeve 501.

[0028] like Figure 1-4As shown, specifically, while the rotating bar 503 rotates, the gear 121 above the rotating bar 503 will also rotate around the axis of the rotating shaft 502. At this time, the annular teeth 122 on the outer surface of the sleeve 501 will drive the gear 121 to rotate. The rotation of the gear 121 will drive the rotating rod 701 to rotate, and the stirring stick 702 on the outer surface of the rotating rod 701 will rotate. At this time, as the rotation of the motor 602 drives the rotating rod 701 to stir, the stirring stick 702 will also rotate by itself, thereby achieving the effect of enhancing the stirring effect.

The extrusion plate 112 is movably fitted to the inner surface of the feed bin 801.

[0030] like Figure 1-4 As shown, specifically, when the silicone product raw materials need to be placed in the heating bin 4 for hot melt treatment, the silicone product raw materials are first put into the feed bin 801 from the feed hopper 802, and then the hydraulic push rod 111 is started. The hydraulic push rod 111 will push the extrusion plate 112, and the extrusion plate 112 will cooperate with the plug plate 803 to extrude the silicone product raw materials. After the extrusion is completed, the plug plate 803 is pulled out, and at this time, the hydraulic push rod 111 is continued to be started, so that the extrusion plate 112 pushes the extruded silicone product raw materials into the heating bin 4 to achieve the feeding effect.
