Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a feeding device for a granulator. Background Art

[0002] The pellet mill is mainly composed of feeding, stirring, granulating, transmission and lubrication systems. The pellet mill can be divided into feed pellet mill and biomass energy pellet mill. The pellet mill has fast pelletizing speed and good effect. The filter screen with special holes is designed for careful screening. The friction filter rod can break and filter solid particles. It is widely used in the pharmaceutical, chemical and food industries. When the pellet mill is in use, a feeding device is usually used to feed the pellet mill.

[0003] After searching: A granulator feeding device with the authorization announcement number CN219669575U relates to the technical field of granulator feeding, including a granulator body, an anti-blocking mechanism is arranged above the granulator body, the anti-blocking mechanism includes a barrel, the inner top wall of the barrel is rotatably connected with a rotating tube, the top end of the rotating tube penetrates the barrel and extends to the top of the barrel, the inner wall of the rotating tube is slidably connected with a moving rod, the top end of the moving rod is fixedly connected with a sliding frame, a slow motor is arranged above the barrel, and the output shaft end of the slow motor is fixedly connected with a rotating disk. It can effectively place the material at the bottom of the barrel to prevent it from being blocked through the arrangement of the granulator body and the anti-blocking mechanism, and avoid the accumulation and blockage of the material at the bottom of the barrel due to the high pressure of the material above, thereby effectively ensuring the normal progress of the feeding process, while reducing the maintenance cost caused by blockage, and facilitating use.

[0004] However, although the above-mentioned granulator feeding device has an anti-blocking effect, the raw materials are prone to moisture adhesion due to long-term storage. The sticky raw material blocks and the larger raw materials themselves will affect the smoothness of feeding and reduce the effect of subsequent granulation. Therefore, we propose a granulator feeding device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings and proposes a feeding device for a granulator.

[0016] In the utility model, a feeding device for a granulator is described. When feeding, the heating rod is turned off and the driving motor is continued to be started, thereby driving the rotation of the breaking rod, which can ensure the fluidity of the raw materials when feeding, making the feeding smoother. At the same time, the servo motor drives the rotation of the toggle piece. Since the toggle piece abuts against the two side walls of the feeding pipe, the raw materials can be fed evenly and smoothly, which not only prevents the occurrence of blockage, but also ensures the uniform and smooth feeding. The power output by the servo motor can be regulated by the controller, and the rotation speed of the roller and the toggle piece can be regulated, so that the feeding speed can be regulated to avoid the situation that the raw materials are blocked in the granulator due to unhurried granulation due to excessive feeding.
