Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of feeding equipment, and specifically relates to a feeding structure of a multi-head combination scale. BACKGROUND

[0002] The multi-head combination scale is also called a computer combination scale, is a special equipment for intelligent quantitative weighing and counting measurement, and is also a core component in an automatic packaging system. The use of the multi-head combination scale can greatly improve production efficiency, reduce material waste, and greatly improve the economic benefits of production enterprises. When in use, the material needs to be delivered to the top of the multi-head combination scale through a feeding equipment, and then is packaged after being weighed by the multi-head combination scale.

[0003] A material lifting machine is disclosed in Chinese patent CN220222456U, which relates to the technical field of material lifting. The material lifting machine comprises a lifting machine body, a cleaning mechanism arranged at the bottom of one side of the lifting machine body, a cleaning structure arranged at the bottom of one side of the lifting machine body, and the cleaning structure is openable. The cleaning structure is used to clean the material blocked at the bottom of the lifting machine body after being opened.

[0004] At present, the feeding equipment of the multi-head combination scale mostly adopts the material lifting machine. The lifting machine often appears to be blocked during the working process. In the above document, the bottom of one side of the lifting machine body is opened after the cleaning structure is opened, so that the material blocked at the bottom of the lifting machine body can be directly cleaned. However, the lifting machine body needs to be manually dredged by the cleaning plate by the worker, which is more troublesome.

[0005] For the problems in the related art, no effective solution has been proposed so far. UTILITY MODEL CONTENT

[0012] Furthermore, the opening and closing assembly includes a second rotating shaft, which is rotatably connected to the silo, and the outer surface of the second rotating shaft is fixedly connected to a swinging plate and an opening and closing plate, and the opening and closing plate is located inside the silo, and a circular hole is opened inside the silo, and a torsion spring is provided inside the circular hole, a group of spring arms of the torsion spring is fixedly connected to the silo, and another group of spring arms of the torsion spring is fixedly connected to the second rotating shaft, and the outer surface of the opening and closing plate is fixedly connected to a dredging rod.

[0013] Furthermore, a protective cover is fixedly connected to the outer surface of the silo, and the linkage assembly and the trigger assembly are both located inside the protective cover.

[0014] Furthermore, the bottom of the silo is fixedly connected with supporting legs.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model connects the linkage component and the trigger component. When the lifting component is working, the lifting component drives the linkage component to rotate, the linkage component drives the trigger component to rotate, and the trigger component pushes the opening and closing component to swing. When the opening and closing component is separated from the silo, the silo is in an open state, and the material in the silo can fall onto the lifting component. When the opening and closing component is closed, the opening and closing component pushes the material in the silo to move, thereby realizing automatic dredging of the silo and avoiding blockage.

[0017] 2. The utility model connects the connecting plate and the swing plate. The first rotating shaft drives the connecting plate and the pulley to rotate, so that the pulley pushes the swing plate to rotate around the second rotating shaft. The second rotating shaft drives the torsion spring to twist it, and the opening and closing plate on the second rotating shaft moves accordingly. When the pulley passes over the swing plate, the swing plate lacks thrust. At this time, the torsion spring can drive the second rotating shaft, the swing plate and the opening and closing plate to return to their original position. As the first rotating shaft rotates, the opening and closing plate can be repeatedly opened and closed.

[0018] Of course, any product implementing the present application does not necessarily need to achieve all the advantages mentioned above at the same time. BRIEF DESCRIPTION OF DRAWINGS
