Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors, and particularly relates to an adaptive slope adjustment device for a belt conveyor. Background Art

[0002] In the fields of modern industrial production and material transportation, belt conveyors, as a widely used continuous conveying device, undertake the important task of efficiently transporting various materials.

[0003] In the daily work of traditional belt conveyors, their slopes are usually fixed or can only be adjusted limitedly through cumbersome manual operations. Due to factors such as the loading method of materials and the characteristics of the materials themselves, the force conditions on each part of the conveyor belt are different, which in turn leads to unsmooth material transportation, problems such as blockage and spillage, seriously affecting production efficiency; secondly, even if some conveyors have slope adjustment functions, their adjustment accuracy often relies on manual measurement and operation to adjust the slope, with large errors, and cannot be adjusted in a timely manner according to the different force conditions of the conveyor belt, resulting in uneven material distribution during the operation of the conveyor, accelerating the wear of the conveyor belt, and shortening the service life of the equipment; in addition, most traditional support structures are fixed and cannot be adaptively adjusted according to factors such as the adjustment of the conveyor slope and vibrations during operation, which leads to uneven force on the conveyor frame, resulting in deformation, shaking, etc. This not only affects the service life of the conveyor but also poses safety hazards.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the content of the present invention easier to be clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

The above connection method ensures that the conveyor body 2 can rotate flexibly around the fixing plate 6 to meet the requirements of different slope adjustments, and can maintain the structural stability during the slope adjustment process; one end of the transmission mechanism 8 is connected to the bottom end of the conveyor body 2; the adjustment mechanism 4 is provided with a controller, which is used to control the working states of each mechanism, and drives the conveyor body 2 to adjust the slope through the transmission mechanism 8; the controller controls the working state of the adjustment mechanism 4 according to the real-time working conditions, so that the adjustment mechanism 4 drives the conveyor body 2 to adjust the slope through the transmission mechanism 8, thereby effectively avoiding the sliding and accumulation of materials during the conveying process and ensuring the stable and efficient conveying of materials.

[0026] Furthermore, support mechanisms 5 are provided on both sides of the top end of the bearing plate 1, and the telescopic ends of the support mechanisms 5 are connected to the conveyor body 2, which provides necessary auxiliary support force for the conveyor body 2; specifically, such as Figure 5As shown, the support mechanism 5 includes: an electric telescopic rod 501 and an electric locking member 502 disposed on one side of the electric telescopic rod 501; the telescopic end of the electric telescopic rod 501 is connected to the ear plate 506 through a fixing member 507, the ear plate 506 is semi-circular, and a chute 508 is formed thereon; the telescopic end of the electric telescopic rod 501 is slidably connected to the chute 508 through a pin shaft 509, and the pin shaft 509 and the chute 508 are used to limit the pallet 504. When the slope of the conveyor body 2 changes, the pallet 504 can rotate along the preset estimation of the chute 508, effectively preventing unnecessary deviation of the pallet 504 during operation, and ensuring the stability and reliability of the entire support mechanism 5; a pallet 504 is provided at the top of the ear plate 506, the pallet 504 is L-shaped and is connected to the conveyor body 2 through a fixing bolt 505; the bottom end of the electric telescopic rod 501 is fixedly connected to the bearing plate 1 through a base 503; both the electric telescopic rod 501 and the electric locking member 502 are electrically connected to the controller; when the controller determines that the slope of the conveyor body 2 needs to be adjusted according to the slope adjustment algorithm, it will send instructions to the electric telescopic rod 501 synchronously, so that it performs elongation or shortening operations according to the predetermined requirements to adapt to the slope change of the conveyor body 2; and when the electric telescopic rod 501 is adjusted to the appropriate position, the controller will immediately send an instruction to the electric locking member 502 to lock the electric telescopic rod 501 in the current position, ensuring a continuous and stable supporting force for the conveyor body 2, and ensuring that the entire conveyor body 2 can operate safely and reliably under various working conditions; the slope adjustment algorithm in the controller calculates the deviation between the set value and the feedback value, and adjusts the control quantity by using three parameters of proportional, integral, and differential, so as to control the operation of each mechanism.

The sensor group 9 is composed of multiple sensors and is arranged at equal intervals along the axial direction of the conveyor belt 201 for detecting the force conditions of various parts on the conveyor belt 201; the sensor group 9 includes pressure sensors and strain gauge sensors; the pressure sensor utilizes the piezoresistive effect of semiconductor materials. When subjected to pressure, its resistance value will change. By measuring the change in the resistance value, the magnitude of the pressure can be detected, and thus the force borne by the conveyor belt can be obtained; the strain gauge sensor can detect the force borne by the conveyor belt by measuring the change in the resistance value and converting the resistance change into a voltage or current signal using circuits such as a Wheatstone bridge; the sensor group 9 is electrically connected to the controller; the sensor group 9 quickly transmits the real-time collected force data to the controller, and the controller makes precise analysis and judgment based on the above force data, thereby timely adjusting the slope and transportation speed of the conveyor body 2 to ensure that the conveyor belt 201 is always in the best working state, guarantee the smoothness and stability of material transportation, improve the operation efficiency and reliability of the conveyor body 2, and thus effectively avoid various failures caused by force, providing continuity and stability for the production process.
