Description

A fan extruder motor

technical field

The utility model relates to an extruder motor, in particular to an extruder motor with a fan.

Background technique

The main engine motor of the extruder will generate a lot of heat when it is running, and it needs to be cooled to work for a long time. The existing cooling method mainly relies on independent fan air cooling. However, independent fan air cooling requires an independent motor to drive the rotation, which consumes additional power. Generally, the blades are designed to be smaller, less in number, and at a lower speed. Due to the small air volume of the independent fan, especially in the case of high temperature in the production workshop, it often causes a series of adverse effects such as overheating and overloading of the coil, tripping of the motor, and stopping production of the production line.

Contents of the invention

The utility model provides an extruder motor with a fan to overcome at least one defect of the above-mentioned prior art. The utility model drives and connects the fan on the main shaft of the motor of the extruder, and the fan rotates to generate wind force to accelerate the air flow speed around the motor, improve the cooling speed, prolong the operating life of the motor in a high-temperature environment, and save electric energy compared with an independent fan. Thereby play a role in reducing costs.

The above-mentioned purpose of the utility model is achieved through the following technical solutions.

An extruder motor with fan includes a motor body, a reducer and a fan, the motor body drives the reducer and the fan to rotate, the reducer is connected between the fan and the motor body through a coupling, and the fan includes a fan blades and a rotating disc for fixing the blades, the blades are forward curved blades.

The utility model drives and connects the fan on the main shaft of the motor of the extruder, and adjusts the speed of the fan through the reducer. The rotation of the fan generates wind to accelerate the air flow speed around the motor, improve the cooling speed, and prolong the operating life of the motor in a high-temperature environment. The use of an independent fan saves power and reduces costs; the blades of the fan are forward-curved blades, which have a larger air volume than those installed on traditional extruders, achieving effective purpose of cooling. The fan blades with a reducer are installed, the number of fan blades increases, and the area increases so that the air volume can be greatly increased, especially under high temperature conditions, which ensures the normal operation of the motor, and the increase of the reducer will not increase the load on the motor, and the power consumption will not increase.

Preferably, the bending angle formed by the front end of the blade is 120 degrees.

Preferably, the number of blades of the fan blades is 48-60.

Preferably, the diameter of the fan is 3/5~1 of the diameter of the motor coil.

Preferably, the reducer is a variable speed reducer.

Preferably, a protective cover is provided outside the fan and the reducer, the protective cover is provided with ventilation holes in the axial direction, and 6-8 through holes are provided in the circumferential direction of the protective cover.

Preferably, the reduction ratio of the reducer is 3-5:1.

Compared with the prior art, the utility model has the beneficial effects that: by driving and connecting the fan on the motor shaft of the extruder, and adjusting the speed of the fan through the reducer, the rotation of the fan generates wind to accelerate the air flow speed around the motor and increase the cooling speed. It prolongs the operating life of the motor in a high-temperature environment, and saves power compared with an independent fan, thereby reducing costs. Installing a reducer increases the number of fan blades and increases the area so that the air volume can be greatly increased, especially under high temperature conditions, ensuring the normal operation of the motor, and the function of the reducer will not increase the load on the motor, and the power consumption will not increase .

Example 1

As shown in Figure 1, a fan extruder motor includes a motor body 1, a reducer 2 and a fan 3, the motor body 1 drives the reducer 2 and the fan 3 to rotate, and the reducer 2 is connected by a coupling Between the fan 3 and the motor body 1, the fan 3 includes a fan blade 31 and a turntable 32 for fixing the fan blade 31. The fan blade 31 is a forward-curved blade. More specifically, the front end of the fan blade forms a The bending angle is 120 degrees. In this embodiment, the fan 3 is driven and connected on the main shaft of the extruder motor main body 1, and the speed of the fan 3 is adjusted through the reducer 2. The rotation of the fan 3 generates wind to accelerate the air flow speed around the motor, improve the cooling speed, and extend the life of the motor. The operating life in a high-temperature environment avoids the use of an independent fan, which saves power and reduces costs; the blades of the fan 3 are forward-curved blades, which are more forward-curved than those installed on traditional extruders. The air volume of the blades is larger, which achieves the purpose of effective cooling; the wind blades of the reducer are installed, and the number of wind blades increases, and the area increases so that the air volume can be greatly increased. More specifically, the number of blades of the wind blades 31 is 56 The diameter of the fan blade 31 is 3/5~1 of the diameter of the motor coil.
