Automatic adjustment type ball forming device for ball rolling machine

Abstract

The invention provides a pelletizing roller automatic regulating type pelletizing device for a steel ball rolling machine, and belongs to the technical field of steel ball processing machinery. The pelletizing roller automatic regulating type pelletizing device comprises a support frame, a pair of rotating drum mechanisms, a pair of pelletizing roller pivoting support frames, a pair of pelletizing rollers, a pair of rotating drum inclination angle regulating mechanisms, a pair of pelletizing roller pivoting support frame regulating mechanisms, a lower ball blocking plate and an upper ball blocking plate, wherein the support frame comprises front and back side upright posts, front and back cross beams and a support frame connecting seat plate, and each pelletizing roller pivoting support frame comprises a bearing seat support plate, front and back bearing seats and a bearing seat connecting fixing plate. The pelletizing roller automatic regulating type pelletizing device is characterized in that the structures of bearing seat leftward and rightward displacement regulating mechanisms connected with the front and back bearing seats are mutually identical and simultaneously work, and each bearing seat leftward and rightward displacement regulating mechanism comprises a support arm support frame, a motor, a speed reducing machine, a speed reducing machine shaft connecting sleeve, a connecting sleeve bearing, a bearing seat leftward and rightward regulating screw rod, a regulating screw rod matching screw nut and a matching screw nut position limiting cover. The manual regulation is not needed, the regulation precision consistency of the front and back bearing seats is ensured, the regulating speed is high, and the locking effect of the front and back bearing seats is ensured.

Description

technical field [0001] The invention belongs to the technical field of steel ball processing machinery, and in particular relates to an automatic adjustment type ball forming device for a ball forming roller of a steel ball rolling machine. Background technique [0002] Steel balls are the medium for ball milling equipment to grind materials. Taking the building materials industry such as cement manufacturers as an example, in the process of producing cement, it is necessary to perform ball milling on the ore that has been crushed by the previous process (crusher crushing). ), while ball milling requires a large number of steel balls with ideal wear resistance and excellent hardness. The production process of steel balls is as follows: the bar (steel round bar) is heated to about 1100°C by the heating furnace, and after it is released from the furnace, it is formed into balls by the ball forming device of the steel ball rolling machine, that is, rolled into balls, and the st...

Problems solved by technology

[0006] But the above-mentioned CN101934334B still has the following shortcomings: one, because the adjustment to the front and rear bearing seats is carried out manually, that is, by manual adjustment, the adjustment is very laborious, especially the larger the size of the ball-forming roller (adapted to Rolling steel balls with large diameters), the adjustment is more laborious, and usually requires the cooperation of multiple people; second, since the front bearing seat and the rear bearing seat must be adjusted together during adjustment, in manual adjustment mode, only the front bearing seat can be adjusted. , Adjust the order of the rear bearing seat, for example, adjust the front bearing seat first, then adjust the rear bearing seat, and vice versa, so that it is difficult to make the front and rear bearing seats achieve the desired effect consistent with each other, that is to say, the difference between the front and rear bearing seats There is an unavoidable adjustment error between the front and rear bearing housings, and the adjustment error between the front and rear bearing housings will affect the radial consistency of the ball forming rollers arranged between the front and rear bearing housings, and ultimately affect the rolling quality of the steel balls; Third, due to the relatively long time spent on manual adjustment, it will delay the timing of the ball forming device being put into work as soon as possible to a certain extent, that is, the long standby time will affect the ball forming efficiency; , the rear bearing seat is connected or the bearing seat adjustment screw that acts on the front and rear bearing seats does not have a locking effect, so the bearing seat adjustment screw will have a tendency to loosen
