[0012] (III) Beneficial effects

[0013] 1. The motor starts to drive the transmission wheel to rotate, and the transmission wheel drives the driven wheel to rotate through two transmission belts.

The external gear will drive the four stirring grids to rotate at the same time. The four stirring grids stir the internal colloid at the same time. During stirring, the heating plate can heat the colloid to prevent solidification during the stirring process of the colloid. The rotating surface of the stirring grid can completely cover the internal space of the mixing barrel.

This way of unloading does not require the colloid to rely on the rubber extraction mechanism to be discharged, because the colloid entering the rubber extraction mechanism may cause the rubber extraction mechanism to be blocked after solidification. Therefore, this way of unloading can achieve the effect of reducing the occurrence of faults. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiment of the present application provides a glue mixing mechanism for a solvent-free compounding machine, which effectively solves the above-mentioned glue mixing mechanism. The colloid is mixed by two blades on a rotating rod. The rotating motor is directly connected to the transmission rod, so that the torque output by the motor is small. In addition, the colloid has a certain viscosity and poor fluidity. Therefore, the technical problem that the colloid cannot be efficiently mixed during use is that the motor starts to drive the transmission wheel to rotate, and the transmission wheel then drives the driven wheel to rotate through two transmission belts. Since the diameter of the transmission wheel is much smaller than that of the driven wheel, the rotational torque of the driven wheel can be increased. The driven wheel will drive the four external gears to rotate through the meshing of the internal inner gear and the external gear. The external gear will drive the four stirring grids to rotate at the same time. The four stirring grids stir the internal colloid at the same time. During stirring, the heating plate can heat the colloid to avoid To prevent the colloid from solidifying during the stirring process, the rotating surface of the stirring grid can completely cover the internal space of the mixing barrel. Therefore, even if the colloid has poor fluidity, the colloid can be fully made to flow for mixing. The driven wheel is driven to rotate by the transmission wheel, thereby driving the four stirring grids to stir at the same time, thereby achieving the effect of improving the mixing efficiency of the colloid. When the mixing is completed, the electric push rod is started and the piston is pulled downward, so that the sealing gasket above the piston can leave the opening at the bottom of the mixing barrel, and at the same time, the sealing gasket under the piston can block the lifting port of the electric push rod, so that the internal colloid can flow out naturally by gravity and enter the storage device along the rubber outlet pipe. This method of unloading does not require the colloid to rely on the glue extraction mechanism to be discharged, because the glue extraction mechanism may be blocked after the colloid enters the glue extraction mechanism and solidifies. Therefore, this method of unloading achieves the effect of reducing the occurrence of faults.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the above-mentioned mixing mechanism, and the colloid is mixed by two blades on a rotating rod. The rotating motor is directly connected to the transmission rod, so that the torque output by the motor is small, and the colloid has a certain viscosity and poor fluidity, so the colloid cannot be efficiently mixed during use. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a glue mixing mechanism for a solvent-free laminating machine, including a glue mixing barrel 1, four stirring grids 2 are evenly and rotatably installed inside the glue mixing barrel 1, and external meshing gears 3 are fixedly installed on the tops of the four stirring grids 2. A driven wheel 4 is rotatably installed on the top of the glue mixing barrel 1, an internal meshing gear 5 is fixedly installed inside the driven wheel 4, and two transmission belts 6 are installed on the driven wheel 4; the external meshing gear 3 is meshed with the internal meshing gear 5.

[0025] A discharge pipe 15 is fixedly installed at the bottom end of the mixing barrel 1, a piston 16 is slidably installed inside the discharge pipe 15, two sealing gaskets 17 are symmetrically fixedly installed at both ends of the piston 16, a heating plate 19 is fixedly installed on the outer wall of the mixing barrel 1, a motor 7 is fixedly installed on the side end of the mixing barrel 1, and a transmission wheel 8 is fixedly installed on the top of the motor 7.

[0026] The driving wheel 8 drives the driven wheel 4 to rotate through the driving belt 6. A feeding pipe 9 is fixedly installed on the top of the mixing glue barrel 1, and two feeding pipes 12 are fixedly installed on the side ends of the feeding pipe 9. A supporting seat 14 is fixedly installed on the bottom end of the mixing glue barrel 1, and an electric push rod 18 is fixedly installed on the top of the supporting seat 14; the electric push rod 18 is fixedly connected to the piston 16, a top cover 13 is rotatably installed on the top of the feeding pipe 9, and a discharging pipe 11 is fixedly installed on the side end of the discharging pipe 15.

[0027] Working principle:

[0028] In the first step, two feed pipes 12 are connected to the feed mechanism and the water supply mechanism respectively, and the rubber outlet pipe 11 is connected to the storage device. The feed pipe 12 delivers the rubber delivered by the feed mechanism to the inside of the rubber mixing barrel 1. The top cover 13 can be rotated to open the feed pipe 9, and the mixed material to be added is put into the rubber mixing barrel 1 through the feed pipe 9. After putting it in, the top cover 13 is closed to prevent the smell from being emitted during the mixing of the rubber. The motor 7 is started to drive the transmission wheel 8 to rotate, and the transmission wheel 8 then drives the driven wheel 4 to rotate through two transmission belts 6. Since the diameter of the transmission wheel 8 is much smaller than that of the driven wheel 4, the rotational torque of the driven wheel 4 can be increased. The driven wheel 4 is meshed internally. The meshing of the gear 5 and the external gear 3 will drive the four external gears 3 to rotate, and the external gear 3 will drive the four stirring grids 2 to rotate at the same time. The four stirring grids 2 will stir the internal colloid at the same time. During stirring, the heating plate 19 can heat the colloid to prevent solidification of the colloid during stirring. The rotating surface of the stirring grid 2 can completely cover the internal space of the mixing barrel 1. Therefore, even if the colloid has poor fluidity, the colloid can be fully made to flow and mix. The driven wheel 4 is driven to rotate by the transmission wheel 8, thereby driving the four stirring grids 2 to stir at the same time, thereby achieving the effect of improving the mixing efficiency of the colloid.

[0029] In the second step, when the mixing is completed, the electric push rod 18 is started and the piston 16 is pulled downward, so that the sealing gasket 17 above the piston 16 can leave the opening at the bottom of the mixing barrel 1, and at the same time, the sealing gasket 17 below the piston 16 can block the lifting port of the electric push rod 18, so that the internal colloid can flow out naturally by gravity and enter the storage device along the rubber outlet pipe 11. This material discharge method does not require the colloid to rely on the rubber extraction mechanism to be discharged, because the colloid entering the rubber extraction mechanism may cause the rubber extraction mechanism to be blocked after solidification. Therefore, this material discharge method achieves the effect of reducing the occurrence of faults.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
