Subsequently, the lifting drive assembly 5 is activated, driving the blocking frame 6 to slide upward along the vertical limit slot, opening the vents. At this point, the heating wire 7 within the preheating installation box 2 begins to generate heat. The air blower 8 then activates, directing the heat toward the vents in the furnace body 1, preheating the material entering. The filter plate 9 blocks impurities, ensuring the purity of the preheated air. This shortens the time required for the material to reach the desired temperature, reduces energy consumption, and ensures a uniform and stable preheating process, thereby improving product quality.
[0023] The positioning pin assembly 3 includes a U-shaped connecting seat 301 and a connecting plug 302. The U-shaped connecting seat 301 is fixed to the top of the preheating installation box 2, and the connecting plug 302 is fixed to the top of the furnace body 1. One end of the connecting plug 302 is inserted into the U-shaped connecting seat 301. An L-shaped connecting plate 303 is fixedly installed on the outer wall of the U-shaped connecting seat 301, and a positioning pin rod 304 is slidably installed on the L-shaped connecting plate 303. One end of the positioning pin rod 304 is inserted into the corresponding positioning pin holes on the U-shaped connecting seat 301 and the connecting plug 302. The other end of the positioning pin rod 304 is fixedly installed with a lifting handle 305. An annular connecting block 306 is fixedly sleeved on the positioning pin rod 304, and the annular connecting block 306 is elastically connected to the L-shaped connecting plate 303 by a tightening spring 307. The preheating installation box 2 is aligned with the furnace body 1 so that the U-shaped connecting seat 301 is aligned with the connecting plug 302 on the top of the furnace body 1. Next, insert the connecting block 302 into the U-shaped connecting base 301 until they fit snugly. Next, pull the handle 305 to push the locating pin 304 along the L-shaped connecting plate 303 until one end of the locating pin 304 accurately inserts into the corresponding locating pin holes on the U-shaped connecting base 301 and the connecting block 302, achieving a secure connection. The tightening spring 307 provides elastic force during this process, ensuring that the locating pin 304 is tightly inserted and prevents loosening. This makes installation quick and easy, significantly improving the stability and reliability of the connection between the preheating installation box 2 and the furnace body 1, enhancing preheating efficiency, and not affecting subsequent heating operations of the furnace body 1.
