The utility model relates to a melt flow rate testing device for a nylon material. The device comprises a guide sleeve and a fan which are arranged on a furnace body and are positioned below a neck mould, the upper end of the guide sleeve is provided with a feeding hole facing the neck mould; a discharge opening is formed in the lower end of the guide sleeve; an air flow channel is formed betweenthe inner wall and the outer wall of the guide sleeve, an air outlet communicated with the air flow channel is formed in the lower end of the guide sleeve, the fan is communicated with the upper end of the air flow channel through an air guide pipe, the fan is connected with the control system, and the scraper is located in the guide sleeve. When the device is used, after the scraper cuts off materials, the materials can impact the guide sleeve under the inertia effect, and due to the fact that cooling air is arranged in the guide sleeve, the materials can be cooled after making contact with the guide sleeve.
