[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-3In an embodiment of the present invention, a paper push chain quick change mechanism comprises a paper push chain 1, wherein the side walls of the paper push chain 1 are respectively provided with a plurality of fixed push blocks 2 and movable push blocks 3, wherein the plurality of fixed push blocks 2 and movable push blocks 3 are arranged in an "ABAB" form, wherein the fixed push block 2 and movable push block 3 are respectively connected to the paper push chain 1 through a first single chain 4 and a second single chain 5, wherein the first single chain 4 and the second single chain 5 have the same structure and both include two front and rear extension pins, wherein the fixed push block 2 is fixedly connected to the two extension pins on the first single chain 4, wherein the movable push block 3 is rotationally connected to the front extension pin of the second single chain 5, wherein the rear extension pin of the second single chain 5 is rotationally connected to a buckle key 6, wherein a limited card plate 7 is fixedly installed on a side of the second single chain 5 close to the paper push chain 1, wherein a limited card slot 8 is provided on a side of the movable push block 3 close to the limit card plate 7, wherein the other end of the buckle key 6 is movably connected to the front extension pin of the second single chain 5, and a card slot 9 is provided on the buckle key 6.

[0017] It is worth noting that the limiting clamping plate 7 is of a rectangular structure, and the clamping slot 8 corresponds to the front end extended pin shaft of the second single chain 5 .

[0018] It is worth noting that the snap key 6 is in an "L"-shaped structure, one end of the snap key 6 rotates around the rear end extension pin of the second single chain 5, and the other end is connected to the front end extension pin of the second single chain 5 through the slot 9, and when the other end of the snap key 6 is connected to the front end extension pin of the front end extension pin of the second single chain 5, the sum of the widths of the snap key 6 and the movable push block 3 is equal to the width of the second single chain 5. The purpose is to ensure that when the movable push block 3 is in a state of parallel or vertical connection with the limiting card plate 7, the movable push block 3 is in a fixed state, so that the connection between the limiting slot 8 and the limiting card plate 7 will not fall off, and when adjustment is needed, since the snap key 6 has freed up enough space, the movable push block 3 can move along the front end extension pin of the second single chain 5.

[0019] It is worth noting that the fixed push block 2 and the movable push block 3 are equidistantly arranged, the fixed push block 2 is in an "L"-shaped structure, the inner angle of which is an obtuse angle, and the extension direction is toward the bottom of the paper pushing chain 1, and the fixed push block 2 and the movable push block 3 are both located on the same side of the paper pushing chain 1.

[0020] It is worth noting that a circular hole is provided on the movable push block 3 which can rotate around the front end extension pin of the second single chain 5 , and the movable push block 3 can move on the front end extension pin of the second single chain 5 through the circular hole.

[0021] Example:

[0022] The paper pack is pushed by the fixed push block 2 and the movable push block 3 arranged on the paper pushing chain 1. When the movable push block 3 is erected, the movable push block 3 remains parallel to the paper pushing chain 1 at this time, and thus cannot generate thrust on the paper pack. This changes the spacing between the push blocks. Since paper packs of different package types correspond to different spacings, the movable push block 3 can play a role of adjustment.

[0023] The snap key 6 is moved to disengage the snap key 6 from the front-end extension pin of the second single chain 5, leaving enough displacement space for the movable push block 3. Then the movable push block 3 is moved along the front-end extension pin of the second single chain 5, so that the limit card plate 7 and the limit card slot 8 can be easily separated. At this time, the movable push block 3 can be erected upward to keep it parallel to the paper pushing chain 1, and then the snap key 6 is re-engaged on the front-end extension pin of the second single chain 5, so that the movable push block 3 is fixed and will not be easily loosened, and the movable push block 3 will not participate in pushing the cardboard package;

[0024] The undulating snap key 6 causes the snap key 6 to disengage from the front end extended pin of the second single chain 5, reserving sufficient displacement space for the movable push block 3, and then the movable push block 3 is moved along the front end extended pin of the second single chain 5, so that the limit card plate 7 and the limit card slot 8 can be easily separated. At this time, the movable push block 3 can be lowered to keep it vertical to the paper pushing chain 1, and then the snap key 6 can be re-connected to the front end extended pin of the second single chain 5, so that the movable push block 3 is fixed and will not loosen easily. At the same time, the movable push block 3 can also participate in pushing the cardboard package.

[0025] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
