Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of an anti-condensation injection feeding mechanism for an injection molding machine, comprising: an injection cylinder 1, a feeding port 5 provided on the top of the injection cylinder 1, a screw 10 provided inside the injection cylinder 1, a rotating seat 9 provided at one end of the screw 10, an end cap 11 provided at one end of the rotating seat 9, a reducer 3 connected to the rear end of the rotating seat 9 via a shaft, and a first motor 4 provided at the rear end of the reducer 3; the first motor 4 drives the screw 10 to rotate, thereby driving the internal material to move towards the injection end through the screw 10;

Multiple electric heating wires are provided inside the arc-shaped electric heating cylinder 12. A control valve 13 is provided at the lower end of the arc-shaped electric heating cylinder 12 and is connected to the feeding interface 5. A material turning assembly is provided inside the arc-shaped electric heating cylinder 12. The material turning assembly includes a turntable 14. Multiple material turning assemblies are arranged in a ring at intervals on the outer wall of the turntable 14. A second motor 8 is provided at the rear end of the turntable 14.

[0024] By setting the feeding tank 6, the material to be injected is fed into the injection cylinder 1 through the feeding port 5. During the feeding and placement process, the material stays in the arc-shaped electric heating cylinder 12 inside. The arc-shaped structure of the electric heating cylinder allows the material to naturally accumulate to the bottom, which facilitates the subsequent feeding of the material in the cylinder directly into the injection cylinder 1 through the control valve 13. The electric heating cylinder heats the cylinder body through an electric heating wire (not shown in the figure), and then heats the material in the cylinder through heat transfer, which has the effect of preventing the material from condensing.

[0025] The top of the feeding tank body 6 is provided with a splash-proof end cover 7, and the outer wall of the feeding tank body 6 is provided with an outer ceramic heat preservation layer 17. The use of the outer ceramic heat preservation layer 17 can effectively improve the heat preservation effect of the tank body, make the internal heat dissipate more slowly, and make the internal material more difficult to condense. The splash-proof end cover 7 avoids throwing the material to the outside during the material turning process, and can improve the sealing performance of the tank body, so that the heat is more difficult to dissipate, and the heat preservation effect is improved.

[0026] The material turning assembly includes a support 15, and the end of the support 15 away from the turntable 14 is provided with an arc-shaped material turning plate 16. The second motor 8 drives the turntable 14 to rotate, so that the arc-shaped material turning plate 16 rotates with the turntable 14. During the rotation, the arc-shaped material turning plate 16 turns the material in the cylinder, so that the material is loose and heated more uniformly.

[0027] Please refer to Figure 4 The outer wall of the injection cylinder 1 is provided with a cylinder heat preservation heating sleeve 2, the inside of the cylinder heat preservation heating sleeve 2 is provided with an electric heater 19, and the outer wall of the cylinder heat preservation heating sleeve 2 is provided with a heat preservation cotton layer 18.

[0028] The multiple electric heaters 19 heat the injection cylinder 1, the heat preservation cotton layer 18 can improve the heat preservation effect of the place, and the heat is more difficult to dissipate.

[0029] Working principle: when in use, the required injection material is sent into the injection cylinder 1 through the feeding tank body 6 and the feeding interface 5. During the feeding and placing process, the material stays in the arc-shaped electric heating cylinder 12 inside. The arc-shaped structure of the electric heating cylinder can make the material naturally accumulate at the bottom, so that the material in the cylinder can be directly sent into the injection cylinder 1 through the control valve 13 in the subsequent process. The electric heating cylinder heats the cylinder body through the electric heating wire, and then heats the material in the cylinder through heat conduction, which has the effect of preventing material condensation.

[0030] The use of the outer ceramic heat preservation layer 17 can effectively improve the heat preservation effect of the tank body, make the internal heat dissipate more slowly, and make the internal material more difficult to condense. The splash-proof end cover 7 avoids throwing the material to the outside during the material turning process, and can improve the sealing performance of the tank body, so that the heat is more difficult to dissipate, and the heat preservation effect is improved.

[0031] The second motor 8 drives the turntable 14 to rotate, so that the arc-shaped material turning plate 16 rotates with the turntable 14. During the rotation, the arc-shaped material turning plate 16 turns the material in the cylinder, so that the material is loose and heated more uniformly.

[0032] The first motor 4 drives the screw rod 10 to rotate, the internal material is driven by the screw rod 10 to move to the injection end, a plurality of electric heaters 19 are used for heating the injection cylinder 1, the material is heated during injection, and the heat preservation cotton layer 18 can improve the heat preservation effect, so that the heat is more difficult to dissipate.
