Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to a novel air-cooling mechanism for granulators. Background Technology

[0002] A granulator is a device used to produce plastic granules. During operation, the granulator first extrudes a hot plastic strip, which then needs to be cooled before being cut into granules. Currently, air cooling is commonly used to cool the hot plastic strip. Existing air cooling devices mostly use fans to directly blow air onto the hot plastic strip for cooling. However, because the air contains dust, and the surface of the hot plastic strip is relatively soft and easily attracts dust, existing air cooling devices cannot filter the dust in the airflow. This results in a large amount of airflow easily contaminating the hot plastic with dust. Therefore, there is an urgent need to develop a new type of air cooling mechanism for granulators that is convenient for cooling plastics and can filter and clean the dust in the airflow, reducing dust contamination on the hot plastic, to overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide a novel air-cooling mechanism for a granulator to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel air-cooled mechanism for a granulator includes a frame, a conveying mechanism, cylinders, a fan, a dust filter, and an automatic dust removal mechanism. The conveying mechanism is installed inside the frame, and multiple cylinders are positioned above it. Each cylinder is fixed to the frame, and a fan is fixedly installed inside each cylinder. The lower end of each cylinder faces the conveying mechanism, and a dust filter is fixedly installed at the upper end. An automatic dust removal mechanism for cleaning the dust filter is connected to each cylinder. The automatic dust removal mechanism includes an industrial vacuum cleaner, a flexible hose, a rigid pipe, a support shaft, a suction nozzle, and a rotating mechanism. The industrial vacuum cleaner is fixed to the ground, and its suction end is connected to the rigid pipe via the flexible hose. A support shaft is fixed to the rigid pipe and rotatably connected to one side of the cylinder. A suction nozzle connected to the rigid pipe is fixed to the rigid pipe. A rotating mechanism for driving the support shaft to rotate is installed on one side of the cylinder.

[0006] Preferably, the rotating mechanism includes a second motor, a first gear, and a second gear. The second motor is fixedly mounted on one side of the cylinder. The first gear is fixed on the output shaft of the second motor. A second gear meshing with the first gear is provided on one side of the first gear. The second gear is fixedly mounted on the support shaft.

[0007] Preferably, the conveying mechanism includes: a transmission roller, a conveyor belt, and a first motor. Two transmission rollers are rotatably connected inside the frame, and the two transmission rollers are connected by a conveyor belt. The first motor is fixed on the frame, and the output shaft of the first motor is fixed to one of the transmission rollers.

[0008] Preferably, the cylinder is inclined.

[0009] The beneficial effects of this utility model are as follows: The novel air-cooling mechanism of this granulator places the high-temperature plastic strips produced by the granulator onto the conveying mechanism, which then transports the plastic strips forward. A fan blows airflow, which first passes through a dust filter and enters the cylinder before being blown from the bottom of the cylinder onto the conveying mechanism to cool the high-temperature plastic strips. The dust filter removes dust from the airflow, reducing contact between dust and the high-temperature plastic strips, thus minimizing dust contamination. Every few days, an automatic dust cleaning mechanism is activated to clean the dust accumulated on the dust filter. An industrial vacuum cleaner performs suction, with a second motor driving the first and second gears. The second gear drives the support shaft, which in turn drives the rigid tube and suction nozzle to sweep across the top of the dust filter, removing the accumulated dust and preventing clogging. In summary, this utility model provides convenient air cooling for plastics and effectively filters and cleans dust from the airflow, reducing dust contamination of the high-temperature plastics.

An automatic dust removal mechanism for cleaning the dust filter 5 is connected to the cylinder 3. Structure 6: During use, the high-temperature plastic strips produced by the granulator are placed on the conveying mechanism 2. The conveying mechanism 2 transports the plastic strips forward. The fan 4 blows airflow, which first passes through the dust filter screen 5 and enters the cylinder 3. Then, it blows from the bottom of the cylinder 3 onto the conveying mechanism 2 to cool the high-temperature plastic strips. The dust filter screen 5 filters out the dust in the airflow, thereby reducing the contact between dust and the high-temperature plastic strips and reducing dust contamination. Every few days, the automatic dust cleaning mechanism 6 is activated to clean the dust accumulated on the dust filter screen 5 to prevent clogging.

[0021] The conveying mechanism 2 includes a drive roller 201, a conveyor belt 202, and a first motor 203. Two drive rollers 201 are rotatably connected inside the frame 1.

The second gear 6063 is fixedly mounted on the support shaft 604. In use, the industrial vacuum cleaner 601 performs suction. The second motor 6061 drives the first gear 6062 and the second gear 6063 to rotate. The second gear 6063 drives the support shaft 604 to rotate. The rotation of the support shaft 604 drives the rigid tube 603 and the suction nozzle 605 to sweep across the upper side of the dust filter 5, thereby sucking away the dust accumulated on the dust filter 5.

[0023] Working Principle: The novel air-cooling mechanism of this granulator places the high-temperature plastic strips produced by the granulator onto the conveying mechanism 2. The conveying mechanism 2 transports the plastic strips forward. The fan 4 blows airflow, which first passes through the dust filter screen 5 and enters the cylinder 3.

Every few days, the automatic dust cleaning mechanism 6 is activated to clean the dust accumulated on the dust filter screen 5. An industrial vacuum cleaner 601 performs suction, which is driven by the second motor 6061 to rotate the first gear 6062 and the second gear 6063. The second gear 6063 drives the support shaft 604 to rotate, and the rotation of the support shaft 604 drives the rigid tube 603 and the suction nozzle 605 to sweep across the upper side of the dust filter screen 5, thereby removing the dust accumulated on the dust filter screen 5 and preventing clogging.
