Description

Technical Field

[0001] This utility model belongs to the field of belt scale technology, specifically relating to a static belt scale weighing guide structure. Background Technology

[0002] The existing conveyor belt structure includes two side plates, at least two rollers, a belt, a transmission device, and a motor. The two ends of the roller's shaft are rotatably connected to the two side plates respectively. The belt is fitted onto the roller. The motor is mounted on the side plate and drives one of the rollers to rotate through the transmission device.

[0003] When it's necessary to calculate instantaneous flow and cumulative volume, the weight of the material on the belt needs to be obtained using a belt scale, and then integrated with the conveyor speed. However, existing belt scales can only weigh horizontally and cannot be adjusted according to changes in the scenario, making them unsuitable for scenarios requiring tilted weighing. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a static belt scale weighing guide structure to solve the problem that existing belt scales can only weigh horizontally, cannot be adjusted according to changes in the scene, and cannot cope with scenarios that require tilted weighing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A static belt scale weighing guide structure includes: Multiple bellows load cells; each bellows load cell includes a weighing end and a fixed end; Base; The base is equipped with multiple pads, and the fixed end of a bellows load cell is fixedly connected to the top surface of a pad, with the weighing end suspended in the air; Multiple weighing connection structures; the top end of one weighing connection structure is rotatably connected to the bottom surface of the conveyor belt side plate, and the bottom end of the weighing connection structure is connected to a weighing end. Both the top and bottom ends of the weighing connection structure can be switched between adjustable and locked states. When the bottom end of the weighing connection structure is in the adjustable state, the distance between the weighing end and the top end of the weighing connection structure can be adjusted. Multiple longitudinal guide transverse limiting structures; the top of one longitudinal guide transverse limiting structure is rotatably connected to the bottom surface of the conveyor belt side plate, the bottom of the longitudinal guide transverse limiting structure is slidably set through the top surface of the base, and the top of the longitudinal guide transverse limiting structure can switch between adjustment and locking states.

[0006] Compared with the prior art, the beneficial effects of this utility model are: This application incorporates multiple weighing connection structures and multiple longitudinal guide lateral limiting structures. When tilted weighing is required, both the top and bottom ends of the weighing connection structure can be switched to an adjustment state. The top end is rotated in the adjustment state until the desired slope is reached, and then switched to the locked state. The bottom end is adjusted to a suitable height and then locked. Similarly, the top end of the longitudinal guide lateral limiting structure is also switched to an adjustment state and rotated until the desired slope is reached, and then switched to the locked state. Furthermore, the bottom end of the longitudinal guide lateral limiting structure is slidably positioned through the top surface of the base, thus requiring no additional adjustment and not affecting the weighing results. When the elastic end of the corrugated pipe load cell is about to deform excessively due to overweight objects, or when uneven distribution of the weighed objects causes excessive deformation of the elastic end of one side of the corrugated pipe load cell, the longitudinal guide lateral limiting structure provides longitudinal guidance while simultaneously limiting the lateral movement of the conveyor belt, preventing damage to the corrugated pipe load cell and tilting of the conveyor belt.

Four weighing connection structures are provided; the top ends of two weighing connection structures are rotatably connected to the bottom surface of one conveyor belt side plate 1, and the top ends of the other two weighing connection structures are rotatably connected to the bottom surface of another conveyor belt side plate 1. The bottom end of each weighing connection structure is connected to a weighing end. Both the top and bottom ends of the weighing connection structures can be switched between an adjustable state and a locked state.
