when the moving element (20) moves towards the direction close to the carrier (10), the first accommodating space (13) is enlarged under the action of the movable part (15); when the moving member (20) moves in a direction away from the carrier (10), the first accommodation space (13) is reduced by the movable portion (15).

7. A loading collar arrangement according to claim 6, wherein the moving member (20) comprises a press (24); the movable part (15) makes reciprocating linear motion along the vertical direction; the material loading lantern ring device still includes:

a work table on which the carrier (10) and the moving member (20) are both arranged;

the first end of the transmission piece (60) is connected with the movable part (15) and can be rotatably arranged relative to the movable part (15), and the second end of the transmission piece (60) is connected with a mounting piece (50) positioned on the workbench and can be rotatably arranged relative to the mounting piece (50); the pressing part (24) is pressed on the transmission piece (60);

a second elastic member (70) disposed between the transmission member (60) and the table.

8. A loading collar arrangement according to claim 7, wherein the press (24) is a roller.

9. A loading collar arrangement according to any of claims 1 to 4, wherein the carrier (10) further has a second feed opening (16), a second feed channel and a second receiving space (18), the second feed opening (16) being arranged at a first end of the second feed channel, a second end of the second feed channel being in communication with the second receiving space (18); the second accommodating space (18) is communicated with the first accommodating space (13) through a first communication channel (191), so that the ring component (1) is sleeved on the pipe fitting (2) in the second accommodating space (18) after the collar component (30) sequentially passes through the first accommodating space (13) and the first communication channel (191).

10. A loading collar device according to claim 9, characterized in that the carrier (10) further has a second communication channel (192), the second communication channel (192) communicating with both the second feed channel and the first receiving space (13); the material loading lantern ring device still includes:

the material receiving part (80) is movably arranged between the second communication channel (192) and the first accommodating space (13) so as to receive incoming materials of the second feeding channel and convey the pipe fitting (2) into the first accommodating space (13).

11. A heat exchanger production line comprising a loading collar arrangement, wherein the loading collar arrangement is as claimed in any one of claims 1 to 10.
