[0025] Example 1

[0026] like Figure 1 As shown, a reciprocating translation mechanism of a feeding piece comprises a fixed plate 1, a feeding tube 4, a connecting rod and a straight rod 9; the straight rod 9 is connected to the connecting rod, and the rotation of the straight rod 9 drives the connecting rod to make a forward and backward reciprocating motion; the connecting rod is connected to the fixed plate 1; when the connecting rod makes a forward and backward reciprocating motion, it will drive the fixed plate 1 to make a forward and backward reciprocating motion; a plurality of openings are provided on the fixed plate 1, and a plurality of feeding tubes 4 are installed on the plurality of openings; the size and shape of the openings on the fixed plate 1 are not limited, and the fixing is carried out according to the size of the feeding tube 4 to be installed to match the shape and size of the openings; a limiting device is installed below the fixed plate 1, and a pulley slot 10 is provided below the pulley 11, which enables the connecting rod to drive the fixed plate 1 to move horizontally back and forth; the limiting device comprises a pulley 11 and a pulley slot 10; the pulley 11 comprises two pulley structures, and the two pulley structures are installed on both sides below the fixed plate; the pulley slot 10 comprises two slot structures, and the two slot structures are respectively arranged below the two pulley structures. The two pulley structures and the two slide groove structures make the forward and backward translation movement of the fixed plate 1 more stable; Figure 3 As shown, the purpose of installing the slide groove is to allow the pulley 11 to move in translation along the length direction of the slide groove to prevent the fixed plate 1 from deflecting during horizontal movement.

[0027] like Figure 1 and Figure 2As shown, the connecting rod includes a first connecting rod 2 and a second connecting rod 3; the first connecting rod 2 is connected to one end of a straight rod 9, and the other end of the straight rod 9 is connected to the second connecting rod 3; a first connecting plate 8 is connected between the first connecting rod 2 and one end of the straight rod 9, and the straight rod 9 rotates to drive the first connecting plate 8; the first connecting plate 8 drives one end of the first connecting rod 2 to make a circular motion, so that the other end of the first connecting rod 2 makes a back and forth reciprocating motion; a second connecting plate 7 is connected between the second connecting rod 3 and the other end of the straight rod 9, and the straight rod 9 rotates to drive the second connecting plate 7; the second connecting plate 7 drives one end of the second connecting rod 3 The straight rod 9 rotates in a circular motion, so that the other end of the second connecting rod 3 reciprocates back and forth; when the straight rod 9 rotates, one end of the first connecting rod 2 and one end of the second connecting rod 3 are simultaneously driven to reciprocate back and forth. Since the first connecting rod 2 and the second connecting rod 3 are both connected to the fixed plate 1, when one end of the first connecting rod 2 and one end of the second connecting rod 3 reciprocate back and forth at the same time, the fixed plate 1 is driven to reciprocate back and forth in translation; the first connecting rod 2 is connected to the fixed plate 1 through the first support rod; the first support rod is fixedly set on the fixed plate 1 through penetration, and the first connecting rod 2 is connected to the first support rod.

Since the first connecting block and the second connecting block are respectively connected to the first connecting rod 2 and the second connecting rod 3, when the straight rod 9 rotates, one end of the first connecting rod 2 and the second connecting rod 3 is driven to make a circular motion, and the other end of the first connecting rod 2 and the second connecting rod 3 is reciprocated back and forth; the first connecting rod 2 and the second connecting rod 3 are both connected to the fixed plate 1, which drives the fixed plate 1 to make a forward and backward translation reciprocating motion, so that the fixed plate 1 drives the unloading tube 4 to make a forward and backward translation reciprocating motion; when the fixed plate 1 moves forward, the unloading material fills the unloading tube 4, and when the fixed plate 1 moves backward, the material filled in the unloading tube 4 is released and fed into the measuring cup, and such reciprocating motion is realized to achieve efficient loading and unloading.
