Material loading equipment for thermal treatment furnace

Abstract

The invention relates to material loading equipment for a thermal treatment furnace. The equipment comprises a frame, a rail component which is arranged on the frame, a hopper which can vertically ascend and descend along the rail component, a transmission mechanism, a travel control device which is in transmission connection with the transmission mechanism and a motor, wherein the transmission mechanism comprises a pair of first chain wheels which is coaxially arranged and is in transmission connection with the motor; each first chain wheel is wound with a chain; each chain is provided with two end parts; and one end part is connected with the hopper, and the other end part is suspended downwards. In the equipment, only one pair of chain wheels and one transmission shaft are required; one end of each chain is connected with the hopper, and the other end of the chain moves around the chain wheel on the upper side and then is freely suspended, so that cost can be reduced, and the structure can be simplified; the tensity of the chains are not required to be adjusted; and a stepping motor is used for driving the transmission shaft to rotate and concentrating the travel control deviceon the upper side of the material loading equipment, the material loading hopper can be precisely controlled to stop at a certain height through the triggering of a plurality of cams, electric wires have short routing paths, and the equipment is easy to maintain and repair.

Description

technical field [0001] The invention belongs to the field of heat treatment equipment, in particular to a material feeding equipment for a heat treatment furnace. Background technique [0002] Metal heat treatment is to heat a metal workpiece in a certain medium to a suitable temperature, and keep it at this temperature for a certain period of time, then cool it at a different speed, and control its performance by changing the surface or internal structure of the metal material. kind of craft. [0003] In the heat treatment industry, it is often necessary to use feeding equipment to put batches of workpieces to be processed into the vibrating machine, and then enter the heat treatment equipment from the vibrating machine. The existing feeding equipment is generally as Figure 5 , 6 As shown, it includes a lifting frame 10 and a protective frame 11. A pair of lower sprockets 12 are coaxially arranged at the bottom of the lifting frame 10, and a pair of upper sprockets 13 are...

AI Technical Summary

Problems solved by technology

[0006] 1. The upper and lower parts of the feeding equipment are equipped with two sets of sprockets and drive shafts for transmission, and the cost of equipment manufacturing and installation is high;

[0007] 2. After the chain is used for a long time, the tension needs to be adjusted, so it is necessary to set up a tension wheel, which not only has high equipment costs, but also high debugging and maintenance costs;
