[0038] It should be noted that the PACK unloading process is as follows: the cam separation component 2 widens the gap between two adjacent sets of separators in the hopper component 4 and inserts them for separation. The push rod unloading module on the unloading channel 1 pushes the PACK at the end of the unloading channel 1 into the gap between the two sets of separators. The push rod unloading module and the cam separation component 2 retract to their original positions. The vertical sliding module in the lifting module lowers by one PACK and two separator thicknesses, and the unloading action of the next set of PACKs continues. After the hopper component is full, the mechanical locking mechanism is released by the magazine limit cylinder, and the full hopper component is slid out along the pull-out guide rail.

[0039] According to an embodiment of the present invention, the cam separation assembly 2 includes two auxiliary mounting plates 210 symmetrically arranged on both sides of the unloading magazine 402. A guide rail 211 is provided on the top of the auxiliary mounting plate 210. A first cam mounting plate 207 is provided on the top of one guide rail 211, and a second cam mounting plate 212 is provided on the top of the other guide rail 211. A cam follower 206 is provided on the top of both the first cam mounting plate 207 and the second cam mounting plate 212.

[0041] According to an embodiment of the present invention, a cylinder mounting plate 204 is provided at one end of the cam track plate 205, a cylinder support plate 201 is provided on one side of the cylinder mounting plate 204, and a separation cylinder 203 is provided at the top of the cylinder support plate 201. The separation cylinder 203 pushes the cylinder mounting plate 204 to move the cam track plate 205. During the movement of the cam track plate 205, the cam follower 206 slides along the guide groove. During the movement of the cam follower 206, the first cam mounting plate 207 and the second cam mounting plate 212 move relative to each other.

[0042] According to an embodiment of the present invention, a separation claw 209 is provided at a relative position between the first cam mounting plate 207 and the second cam mounting plate 212.

[0044] It should be noted that the specific operating process of the cam separator is as follows:

[0045] In the initial state of the separating cylinder, the distance between the two separating claws is at its maximum, and the separating cylinder is in the extended state. When it is necessary to separate the two adjacent layers of separators, the separating cylinder drives the cam track plate to retract, and at the same time, the cam follower slides in the guide groove, so that the separating claws on both sides move relative to each other and insert into the two adjacent layers of separators. The opening and closing of the separating claws can be flexibly controlled by setting the cam follower.

[0046] According to an embodiment of the present invention, the push rod feeding module 5 includes a vertical plate 508 fixedly installed on one side of the feeding channel 1. An auxiliary guide rail is provided on one side of the vertical plate 508. A support end fixing plate 509 is provided at one end of the auxiliary guide rail. A nut mounting block 510 is connected to one side of the auxiliary guide rail. A lead screw 511 is provided at one end of the support end fixing plate 509. The lead screw 511 passes through the nut mounting block 510. A stepper motor 501 is provided at the other end of the lead screw 511. The stepper motor 501 is used to control the nut mounting block 510 to move horizontally along the auxiliary guide rail. Limit blocks 502 are provided at both ends of one side of the vertical plate 508.

[0047] According to an embodiment of the present invention, a connecting plate 503 is connected to the top of the nut mounting block 510. A fixed base 507 is provided at the top of one end of the connecting plate 503. A positioning shaft 504 and a torsion spring 512 are provided at one end of the fixed base 507. The positioning shaft 504 is inserted into the inside of the torsion spring 512. A bearing 505 is hinged to one side of the positioning shaft 504. A push rod 506 is movably connected to one side of the bearing 505.

[0048] It should be noted that the operation process of the push rod feeding module is as follows:

[0049] The lead screw is rotated by a stepper motor, which drives the lead screw nut mounting block to move horizontally back and forth. During the movement of the nut mounting block, the top connecting plate and push rod are moved synchronously. The push rod is a return mechanism. When the push rod is in the original position, it is in a pressed-down state to facilitate the flow of the Pack tray on the belt. When the Pack tray flows to the predetermined position, the sensor detects that the Pack tray is in place, and the push rod moves to push the Pack tray on the flow channel into the gap of the separator and into the unloading magazine.

[0050] According to an embodiment of the present invention, the hopper assembly 4 includes a hopper bottom plate 405, a pull-out guide rail 406 is provided on the top of the hopper bottom plate 405, a feeding clip 402 is connected to the top of the pull-out guide rail 406, the feeding clip 402 can slide along the pull-out guide rail 406, a clip limiting cylinder 403 is provided at the bottom of the hopper bottom plate 405, a clip limiting block 404 is provided on the top of the clip limiting cylinder 403, the clip limiting cylinder 403 controls the clip limiting block 404 to move vertically to fix the feeding clip 402, and a handle 401 is provided on one side of the feeding clip 402.

[0051] It should be noted that the feeding magazine is guided and positioned by a linear guide rail. The feeding magazine is originally in the material receiving position of the Pack tray. The feeding magazine consists of 6 guide posts and a base plate. The 6 guide posts are mounted on the bottom plate of the material bin, and the bottom plate of the material bin is fixed on the pull-out guide rail. Under normal working conditions, the feeding magazine receives material in its original position. After the material is fed, the mechanical locking mechanism automatically unlocks, and the feeding magazine is manually pulled out. After the Pack tray is removed, the feeding magazine is pushed back to its original position, and the photoelectric sensor checks whether it is in place.

[0052] According to an embodiment of the present invention, the lifting module 3 includes a lifting mounting base plate 307 fixedly installed at the bottom of one end of the unloading channel 1. A module back plate 305 is provided at one bottom end of the lifting mounting base plate 307. A vertical sliding module 304 is provided on one side of the module back plate 305. A lifting slider is connected to one side of the vertical sliding module 304. A plurality of partition plates 309 are provided at the top of the lifting slider. A counterweight 301 is provided at the top of the partition plates 309. A top guide rod 303 is provided at the top of the counterweight 301. A top fixing plate 302 is provided at the top of the top guide rod 303. A reinforcing rib 306 is provided at the bottom of the lifting mounting base plate 307. The reinforcing rib 306 is fixedly installed on one side of the module back plate 305. A lifting slider fixing plate 308 is provided at the top of the lifting mounting base plate 307. The lifting slider fixing plate 308 is installed on one side of the lifting slider.

[0053] It should be noted that the lifting module includes two rows of several layers of partition plates arranged in parallel. The unloading clip is located on the inner side. During the unloading process, the cam separation component opens up the partition plates of two adjacent layers for unloading the PACK. In addition, the counterweight can press down several layers of partition plates to ensure that the two adjacent layers of partition plates fit together without creating a large gap. After the PACK tray is placed in two layers of partition plates, the downward pressure of the counterweight can reset the two opened partition plates, so that the PACK tray is firmly placed in the gap between the two adjacent layers of partition plates.

[0054] In summary, by widening the gap between two adjacent separator plates using the cam dividing assembly, the push rod feeding module controls the push rod to precisely push the PACK disc along the gap between the separator plates into the feeding clip, preventing PACK feeding disc jamming and significantly improving production line efficiency and stability.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
