Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a material collecting structure for granulators. Background Art

[0002] The inclined high-power granulation testing machine can be used as a formula exploration and formula optimization and upgrading equipment for various industrial material mixing and granulation formal products before production. Because the equipment has a high degree of automation, a small footprint, simple operation, a small amount of material input in a single batch, and high test efficiency, it can shorten the time from early demonstration to later production, and provide a basis for the selection of later production models and the design of other auxiliary machines; therefore, it is widely used by major company laboratories and scientific research institutes.

[0003] In the prior art, when the granulating test machine is unloading, the mixing disk is driven by a hydraulic cylinder to flip and unload. Although the unloading efficiency can be improved, some dust will be contained in the material. The dust will be dispersed into the surrounding environment during the dumping process, causing dust to fly. The dust is easily inhaled into the lungs of the operator, affecting the operator's health. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, the utility model provides a material collecting structure for a granulator.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a material collecting structure for a granulator, comprising a granulator body, a mixing disk is installed on the granulator body, a stirring roller is movably installed in the mixing disk, a discharge pipe is movably installed at the bottom axis of the mixing disk, a feed port is opened on the top side wall of the discharge pipe, a linear drive component for driving the discharge pipe to move is arranged on the granulator body, and a scraper component is fixedly installed at the bottom of the stirring roller.

[0006] Furthermore, the linear drive assembly includes a hydraulic rod, which is fixedly mounted on the granulator body, and a push plate is fixedly mounted on the power output shaft of the hydraulic rod, and the push plate is fixedly mounted on the side wall of the discharge pipe.

[0007] Furthermore, the scraper assembly comprises a fixing ring, which is fixedly mounted on the bottom end of the stirring roller, and two groups of scraper plates are fixedly mounted on the side of the fixing ring.

[0008] Furthermore, a material blocking boss is provided at the top of the scraper plate.

[0009] Furthermore, a groove matching the diameter of the discharge pipe is formed at the bottom end of the stirring roller.

[0010] Furthermore, a flange is provided at the bottom end of the discharge pipe.

[0011] The beneficial effect of the utility model is that the design of the utility model is designed with a discharge pipe movably installed at the bottom axis of the mixing disk. When unloading, the discharge pipe is driven to rise through the linear drive component, and the feed port is made flush with the bottom wall of the mixing disk. The material in the mixing disk enters the discharge pipe through the feed port under the action of gravity. At the same time, the stirring roller rotates, and the scraper assembly pushes the material deposited at the bottom of the mixing disk to the discharge port. Finally, the material is collected by a collection box connected to the discharge pipe, thereby avoiding dust during unloading and ensuring the health of the operator.
