The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, the present invention relates to a noise reduction type twin-screw extruder.

Examples

Provides a noise reduction type double-screw extruder, which comprises a bracket 5, wherein an insulating layer 12 is arranged on the bracket 5, the upper surface of the heat preservation layer 12 is provided with a feed hopper 4, the front side surface of the heat preservation layer 12 is provided with a discharge hole 15, the rear side surface of the heat preservation layer 12 is embedded with a motor 3, the inner wall of the heat preservation layer 12 is provided with a heating block 10, a screw rod 9 is arranged in the heat preservation layer 12, the screw rod 9 is fixedly connected with the motor 3, a water tank 7 is arranged below the front end of the heat-insulating layer 12, a supporting foot 1 is arranged below the bracket 5, a connecting sleeve 2 is arranged between the supporting foot 1 and the bracket 5, a spring 16 is arranged in the connecting sleeve 2, supporting blocks 19 are arranged above and below the spring 16, a second supporting column 17 is arranged in the spring 16, and the supporting blocks 19 are tightly connected with the bracket 5 and the supporting legs 1.

The insulating layer 12 is externally sleeved with a noise reduction layer 13, the noise reduction layer 11 is arranged on the bracket 5, a second support column 17 is arranged between the noise reduction layer 13 and the insulating layer 12, and the second support column 17 is an elastic soft column. The layer 13 of making an uproar falls is used for reducing the noise that produces when screw rod 9 rotates, makes the noise reduction, and the second support column 17 also can absorb the part, and the decibel of noise reduction has effectively been avoided the noise by direct transmission from heat preservation 12 and has come into the filtration of the layer 13 of making an uproar falls, has played the effect of noise reduction.

The inner wall of the heat-insulating layer 12 is provided with a noise reduction block 11, and the noise reduction block 11 is provided with the heating block 10. Heating block 10 also can produce the noise when heating, and when making an uproar piece 11 and heating block 10 contact fall, fall and fall piece 11 and can directly partly absorb the noise that heating block 10 produced, and simultaneously, fall piece 10 and can also partly absorb the noise that screw rod 9 during operation produced, played the effect of effective noise reduction.

A first buffer layer 8 is arranged between the motor 3 and the heat-insulating layer 12, and a second buffer layer 18 is arranged between the bracket 5 and the noise reduction layer 13. When screw rod 9 and motor 3 rotate, can drive heat preservation 12 and the layer 13 of making an uproar that falls produces the shake, this kind of shake also is the source that the noise produced, moreover, when heat preservation 12 and the layer 13 shake of making an uproar that falls acutely time, the noise of production can increase, and, after heat preservation 12 and the long-time acutely shake of the layer 13 of making an uproar that falls, the condition of scattered frame can probably appear in this extruder, use behind first buffer layer 8 and the second buffer layer 18, can effectually reduce the heat preservation 12 and the shake range of the layer 13 of making an uproar that falls, the noise abatement has been played, the life's of extension extruder effect.

The first buffer layer 8 and the second buffer layer 18 are made of rubber. Rubber itself is comparatively soft, has great elasticity and can produce great deformation, when heat preservation 12 and the layer 13 of making an uproar that falls produced the shake, first buffer layer 8 with second buffer layer 18 can follow the shake production change of heat preservation 12 and the layer 13 of making an uproar that falls, produce the shake with heat preservation 12 and the layer 13 of making an uproar that falls and absorb, make the effect of buffering reach the best, played extension extruder life's effect.

Wherein, the front side surface of the heat-insulating layer 12 is provided with a cooling device 6. When the material is extruded from the discharge port 15, the material falls into the water tank 7, ice water is contained in the water tank 7, and the material is cooled after contacting the ice water, but the temperature of the ice water rises after contacting the material due to the fact that the extruded material has high temperature, and the cooling effect of the ice water is reduced along with the temperature rise of the ice water, so that the ice water needs to be frequently replaced by workers, the cooling effect is kept to be optimal, after the cooling device 6 is arranged, the cooling device 6 can reduce the temperature of the extruded material before contacting the ice water, the rising speed of the temperature of the ice water is reduced, the frequency of replacing the ice water by the workers is reduced, and the effect of saving manpower is achieved.

The working process of the example is as follows:

firstly, a power supply is needed to be connected to the extruder, then a motor 3 and a heating block 10 are opened, ice water is filled in a water tank 7, the motor 3 drives a screw rod 9 to rotate, the heating block 10 enables the temperature in an insulating layer 12 to rise, then a worker pours materials into a feed hopper 4 so as to enable the materials to enter the insulating layer 12, then the heated and softened materials are extruded from a discharge port 15, when the extruder works, a spring 16 can absorb partial vibration generated by the extruder, the vibration is mainly generated by driving the insulating layer 12 and a noise reduction layer 13 when the screw rod 9 and the motor 3 rotate, the spring 16 plays a role of buffering after deformation and compression, so that the vibration amplitude of the extruder is reduced, and the noise generated when the extruder works can be effectively reduced due to the vibration, when the extruder shakes, the supporting legs 1 can generate friction with the ground, the friction generated creates noise, so the spring 16 is effective in reducing the magnitude of the wobble.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
