9. A feeder for liquid epoxy resin production according to claim 8, characterized in that: A lifting cylinder (91) is fixedly mounted on the top of the material storage box (3), and the protruding end of the lifting cylinder (91) movably penetrates the material storage box (3) and is fixedly connected to the lifting sleeve (92).

10. The method for using the feeder for liquid epoxy resin production according to any one of claims 1 to 9, characterized in that: The method of use specifically includes the following steps: Step 1: After the liquid epoxy resin in the storage box (3) is fed, the water pump (5) is turned on, and the cleaning liquid is injected into the lifting sleeve (92) through the hose (94). At this time, the protruding end of the lifting cylinder (91) is in the shortest state, and the cleaning liquid in the lifting sleeve (92) will flow out along the gap between it and the outer wall of the feed pipe (10). The protruding end of the lifting cylinder (91) is controlled to be extended to the longest, and the lifting sleeve (92) slides down, so that the sealing ring (93) closes the top of the lifting sleeve (92), and the cleaning liquid in the lifting sleeve (92) will be sprayed out from the gap between its bottom and the outer wall of the feed pipe (10), so as to flush and clean the solidified epoxy resin accumulated on the outer wall of the output end of the feed pipe (10); Step 2: by turning on the feeding pump (2), the cleaning liquid passes through the feeding pump (2), is injected into the feeding pipe (11) through the connecting pipe (1), and then is discharged from the output end of the feeding pipe (11), the extended end of the second regulating cylinder (811) is controlled to shrink from the longest to half the length, and the feeding pump (2) is turned off, so that the sealing plug (814) blocks the input end of the feeding pipe (11), preventing the cleaning liquid in the feeding pipe (11) from flowing out, and soaking the epoxy resin cured at the bottom of the inner wall of the feeding pipe (11); Step three: Control the extended end of the first regulating cylinder (852) to extend to its maximum length, drive the second electric heating plate (853) to move downward, so that the groove provided thereon contacts the outer wall of the feeding tube (11). During this process, the transmission rod (857) moves downward, cooperates with the first lever to drive the flip frame (854) and the first electric heating plate (855) to flip, so that the groove provided on the first electric heating plate (855) also contacts the outer wall of the feeding tube (11). At the same time, turn on the first electric heating plate (855) and the second electric heating plate (853) to heat the input end of the feeding tube (11), so as to facilitate the rapid softening of the epoxy resin cured inside it.
