Problems solved by technology

The current design of the belt feeder strives to reduce the size and weight while satisfying the large feeding volume. The design of the feeder body is relatively short, so that the bin pressure area and the discharge area are basically connected. For example, in order to increase the metering function , the metering device is installed under the conveyor belt of the belt feeder. Due to the influence of pressure changes on the conveyor belt by the warehouse pressure zone and the discharge zone, the accuracy of the measurement results is low and the error is large, which cannot reach the material conveying system. Accuracy Requirements

Embodiment 1

[0025] Such as figure 1 , figure 2 , a dynamic weighing belt feeder consisting of a feeding part a and a weighing part b.

[0026] The feeding part a includes a frame 5, a material guide trough 2, a tensioning device 4, a conveying device 8 and a driving device 3, and the conveying device 8 is composed of a driving drum 6, a redirecting drum 10, a conveyor belt 7 and a load-bearing roller 9, Conveyor belt 7 is made up of adhesive tape 7.1 and nail belt 7.2. The driving drum 6 and the redirecting drum 10 are respectively installed at both ends of the frame 5, the endless tape 7.1 surrounds the driving drum 6 and the redirecting drum 10, the armor belt 7.2 surrounds the tape 7.1, and between the driving drum 6 and the redirecting drum 10 Some bearing rollers 9 are set below the conveyer belt 7 upper section. The conveyor belt 7 of the conveying device 8 is provided with a material guide trough 2 , the lower part of the material guide trough 2 is fixed on the frame 5 , and th...

Embodiment 2

[0035] Such as Figure 6 , Figure 7 , a dynamic weighing belt feeder is composed of a feeding part a and a weighing part b, and the weighing part b includes a weighing idler roller 11, a scale frame 12, a load cell 13, and a speed sensor 19. Its basic structure is as follows: a weighing idler 11 is set under the upper section of the conveyor belt 7 in the stable area C section between the bin pressure area A and the discharge area B. In order to make the load cell 13 evenly stressed, three weighing idlers are set 11. Three weighing rollers 11 are placed on a scale frame 12, and the scale frame 12 is placed on four load cells 13, and the load cells 13 are fixed on the frame 5, and the load cell 13 is provided with a height adjustment screw rod 13.1 , the height of the weighing frame 12 can be adjusted by rotating the hand wheel 13.2 on the adjusting screw rod 13.1.

[0036] Since the scale frame 12 is mainly subject to its own gravity and the pressure from the supporting rol...

Abstract

The invention relates to a dynamic weighing belt feeder which consists of a feeding part and a weighing part, wherein, the feeding part comprises a frame, a guide chute, a tensioning device, a conveying appliance and a drive unit; the weighing part comprises a weighing supporting roller, a weighing frame, a weighing sensor and a velocity sensor; the feeding part is divided into a storehouse pressing region, a stabilizing region and a discharging region; and the weighing supporting roller of the weighing part is arranged in the stabilizing region between the storehouse pressing region and the discharging region of the feeding part, the weighing frame is arranged under the weighing supporting roller, the weighing sensor is arranged between the lower part of the weighing frame and the frame, and the velocity sensor is arranged on a rolling drum or the supporting roller. The dynamic weighing belt feeder has the advantages of large feeding quantity, small volume, high weighing precision, is simple to use and maintain smash resistance, wear resistance, water resistance and explosion prevention, thus can be applied to severe environment.

Description

technical field [0001] The invention belongs to bulk material reloading and feeding metering equipment, in particular to a dynamic weighing belt feeder. Background technique [0002] At present, with the improvement of the automation degree of the bulk material conveying system and the improvement of the conveying efficiency of the conveying equipment, the conveying efficiency and functional requirements of the reload feeding equipment are also getting higher and higher, and it has a metering function in the reload feeding process of the bulk material Advanced equipment, especially reloading and feeding equipment with dynamic metering function, has been more and more widely used. [0003] At present, the belt weighing feeder is a relatively mature dynamic metering and reloading feeding equipment used in the bulk material conveying system. The belt weighing feeder is generally composed of a belt conveyor and a metering device. The belt conveyor The idler roller under the bel...
