When the liquid resin in the barrel is used up, the transfer robot 5 first grabs the empty barrel and places it in the storage rack 2, and then grabs the new barrel and transfers it to the lifting rack 43.

The first rotating shaft 14 slides in the limiting groove 27 in the vertical direction. One end of the first rotating shaft 14 extends out of the lifting block 422 and is fixedly installed with a rotating block 15. The side wall of the rotating block 15 is in contact with the side wall of the lifting block 422, and the lifting frame 43 is fixedly installed on the side wall of the rotating block 15 away from the lifting block 422. A counterweight block 33 is fixedly installed at the bottom end of the lifting frame 43, and the counterweight block 33 makes the weight of the lifting frame 43 on the upper and lower sides of the first rotating shaft 14 equal.

In the present application, the elastic reset member 213 can be a torsion spring.

[0045] When the lifting block 422 drives the barrel to move upward, the lifting block 422 drives the driving gear 17 to move upward on the driving rack 16, and the driving gear 17 drives the second rotating shaft 18 to rotate, and the second rotating shaft 18 drives the pawl 212 to rotate, and the elastic reset member 213 pushes the pawl 212 to be engaged in the ratchet 211, thereby driving the driving wheel 19 to rotate, and the driving wheel 19 then drives the rotating block 15 to reciprocate through the eccentrically arranged connecting rod 20, and the rotating block 15 drives the barrel to swing back and forth through the lifting frame 43. The linear liquid resin will be stretched during the rising process of the barrel, and the barrel will swing back and forth at this time, so as to facilitate the rapid disconnection of the linear liquid resin. When the lifting block 422 moves downward, the pawl 212 moves past the ratchet 211, and the second rotating shaft 18 will not drive the driving wheel 19 to rotate, so that the barrel will not swing.

When the lifting block 422 rises to the top of the lifting cover 421, the first driving block 28 is inserted into the slot 30 and drives the first limit plate 24 to move into the limit slot 27. The first limit plate 24 drives the second limit plate 25 into the limit slot 27 through two connecting rods 26, and the first magnetic member 35 on the connecting rod 26 attracts the second magnetic member 36 at one end of the slide slot 34, so that the first limit plate 24 and the second limit plate 25 are always kept in the limit slot 27.

[0050] When the lifting block 422 moves downward, the first limit plate 24 and the second limit plate 25 are located in the limit groove 27, thereby limiting the rotation block 15 so that the rotation block 15 does not swing when it moves downward. When the lifting block 422 descends to the bottom of the lifting cover 421, the second driving block 29 is inserted into the withdrawal groove 31 and drives the second limit plate 25 to move out of the limit groove 27. The second limit plate 25 drives the first limit plate 24 to withdraw from the limit groove 27 through two connecting rods 26, and the first magnetic member 35 on the connecting rod 26 attracts the second magnetic member 36 at the other end of the slide groove 34, so that the first limit plate 24 and the second limit plate 25 always remain outside the limit groove 27.
