Next, the flow of the operation of melting the long metal material 8 into the molten metal by the present embodiment will be described:

referring to fig. 3 and 5, first, the loading platform 3 is driven to move from the preparation position to the ascending position, and then the arm 43 of the pushing unit 4 is driven to engage with the loading seat 33.

Referring to fig. 10, the pushing unit 4 drives the loading base 33 into the feeding chamber 12, and the sliding plate 333 moves to the open position, so that the rightmost elongated metal piece 8 falls into the channel 13 due to gravity and is blocked by the swing arm 54.

Referring to fig. 12, the packing seat set 52 can be lowered to the same height as the feeding chamber 12, and the pusher block 523 is pushed against the leftmost strip 8.

It should be noted that, since the long metal material 8 is vertically arranged in the present embodiment, when the material pushing block 523 pushes the long metal material 8, the long metal material 8 on the rightmost side is pushed to the upper side of the material outlet 334 to naturally fall down by gravity, and the present embodiment can fill materials without an existing turnover mechanism, so that the structure is simplified, and the filling manner is convenient and labor-saving.

Referring to fig. 13, the pushing element 53 is driven to descend until the first pushing portion 531 pushes against the top surface of the elongated metal piece 8 blocked by the swinging arm 54, the first end 541 of the swinging arm 54 rotates downward by the downward moving force of the pushing element 53 against the elastic force of the swinging arm 54, and the second end 542 rotates upward and pushes against the elastic member set 55, so that the elongated metal piece 8 can gradually enter the furnace chamber 11 through the passage 13 to be melted into molten metal.

Referring to fig. 14, when the pushing element 53 continues to move downward until the second pushing portion 532 contacts the pulling portion 543 of the swinging arm 54, the swinging arm 54 is completely pushed away from the channel 13, and the elongated metal piece 8 falls directly into the furnace chamber 11.

Referring to fig. 15, as long as the pushing element 53 is driven to first rise to the original position and the above feeding manner is repeated, each of the strip-shaped metal pieces 8 is conveyed to the furnace chamber 11 for heating and melting, and no material remains after each of the strip-shaped metal pieces 8 is melted, so that the present invention can improve the existing disadvantages and maintain the smooth operation of the machine.

In some embodiments, the vertical feeding device 200 can also change the vertical erection of the elongated metal pieces 8 into the horizontal stacking mode, and when the elongated metal pieces 8 are fed into the feeding chamber 12, the elongated metal pieces 8 are turned one by one to be erected and then fed into the channel 13, and the swing arm 54 can be pushed completely out of the channel 13 by the second pushing portion 532 of the pushing member 53, so that each elongated metal piece 8 directly falls into the furnace chamber 11, which can also improve the existing disadvantages and maintain the smooth operation of the machine.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
