我厂铸造车间于一九七九年自制了一台电热补带机,用于该车间十二条带式输送机橡胶带接头的补接,经四年多来的使用,效果良好。该机造价低廉,适合中小铸造车间供带宽小于1000毫米的橡胶输送带连接之用。该机的结构见图1,由上、下部双梁和拉紧螺栓、压紧螺钉、垫板及上、下电阻板等组 In 1979, our factory founding a self-made electric heating belt machine in the foundry workshop, which was used to supplement the rubber belt joints of twelve belt conveyor in the workshop. After more than four years of operation, the effect was good. The machine low cost, suitable for small and medium foundry workshop for the bandwidth of less than 1000 mm rubber conveyor belt connection purposes. The structure of the machine shown in Figure 1, from the upper and lower double beams and tension bolts, compression screws, plate and the upper and lower resistance plate group
