Embodiment 1

[0028] see Figure 1 ~ Figure 2 , a flux-cored wire belt-type powder feeder, including a powder feeding belt 4, a front shaft 1 and a rear shaft (not shown in the figure), the powder feeding belt 4 is tensioned on the front shaft 1 and the rear shaft, and the front shaft 1 Installed on the front axle bracket 5, the front axle 1 is provided with a supporting shaft 3 parallel thereto, the supporting axle 3 is installed on the front axle bracket 5, and the two ends of the front axle 1 are respectively equipped with bearings 7, and the bearings 7 at the two ends of the front axle are respectively Embedded in the two supporting chutes provided on the front axle bracket 5, the two supporting chutes of the front axle bearing 7 are parallel to each other, and its characteristics are:

[0029]Between the front shaft 1 and the support shaft 3, there is also a transition shaft 2, the support shaft 3 is in friction connection with the transition shaft 2, the transition shaft 2 is in frict...

Embodiment 2

[0033] see Figure 3 ~ Figure 4 , a flux-cored wire belt-type powder feeder, the difference from Example 1 is that: between the front shaft 1 and the support shaft 3, there are five transitional shafts 2a, 2b, 2c, 2d, 2e that are sequentially frictionally connected. Bearings are installed at both ends of each transition shaft. The transition shaft 2a adjacent to the front axle and the bearing on the same side of the front axle 1 are embedded in the same stepped support chute, and the front axle bracket 5 is provided with two parallel and symmetrical stepped support chute; The bearings on the same side of the four transition shafts 2b, 2c, 2d, and 2e behind the adjacent transition shaft 2a are embedded in the same transition shaft slide groove, and the front axle bracket 5 is provided with two parallel transition shaft slide grooves. And, the center of the transition shaft 2a adjacent to the front shaft is located below the angle bisector 6 of the front shaft wrap angle of the...

Embodiment 3

[0037] see Figure 5 ~ Figure 6 , a flux-cored wire belt-type powder feeder, the difference from Embodiment 1 is that two transition shafts 2a, 2b which are sequentially frictionally connected between the front shaft 1 and the support shaft 3, and the two ends of each transition shaft Both bearings are installed, and the bearings on the same side of the front axle 1 and the adjacent transition axle 2a are embedded in the same stepped support chute, and the front axle support 5 is provided with two parallel and symmetrical stepped support chute; The bearings at both ends of the transition shaft 2b behind the transition shaft 2a adjacent to the front axle are embedded in the transition shaft sliding grooves, and the front axle bracket 5 is provided with two parallel transition shaft sliding grooves. At this time, the movement direction of the surface of the support shaft 3 is opposite to that of the inside of the powder feeding belt, and the guide shaft assembly 11 needs to be s...

Abstract

The invention discloses a flux-cored wire belt type powder feeder which comprises a powder feeding belt, a front shaft and a rear shaft, wherein the powder feeding belt is tensioned on the front shaft and the rear shaft; the front shaft is arranged on a front shaft bracket; a supporting shaft parallel to the front shaft is arranged behind the front shaft and is installed on the front shaft bracket; a transition shaft connected with the front shaft bracket is also arranged between the front shaft and the supporting shaft; the front shaft, the transition shaft and the supporting shaft are frictionally connected with one another in sequence; the transition shaft is parallel to the front shaft and the supporting shaft; when the number of the transition shaft is 1, the centers of the front shaft, the transition shaft and the supporting shaft which are frictionally connected with one another in sequence are not collinear; and when the number of the transition shaft is more than 1, the centers of the transition shafts are arranged in a mode that the direction of the connecting line of the centers of two adjacent transition shafts is opposite to the directions of the connecting lines of the centers of previous shafts and posterior shafts of the two adjacent transition shafts. According to the invention, the included angle of the powder feeding belt at the front shaft can be reduced tofulfill the aim of reducing the powder feeding drop height.

Description

technical field [0001] The invention belongs to the field of manufacturing welding rods for brazing or welding, belongs to the one point group of IPC classification B23K35 / 40, belongs to the manufacturing technical group of ECLA classification number B23K35 / 40F cored tubular welding wire or welding rod, and particularly relates to a flux-cored wire belt-type powder feeder . Background technique [0002] At present, the powder feeding system of the flux-cored welding wire forming machine generally adopts a belt-type powder feeder, such as the patent document CN20154373U, the wire rolling machine powder feeder disclosed on August 11, 2010. In front of the belt, it makes centripetal movement around the center of the front axis of the powder feeder. When the adsorption force between the powder and the belt is not enough to provide centripetal force, the powder will be thrown out, leave the surface of the belt, and fall into the U-shaped groove of the steel belt. . The diameter...
