[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0026] Reference Figure 1 as well as Figure 2 This application provides a feeding and positioning mechanism for cigarette packs, including a base 1, a feeding structure 2 disposed on the base 1, and a positioning and conveying structure 3. When the feeding and positioning mechanism is running, the feeding structure 2 feeds the pack into the positioning and conveying structure 3, and the positioning and conveying structure 3 positions and conveys the pack to cooperate with subsequent processes.

[0027] Specifically, the feeding structure 2 is located at one end of the base 1 along its length. The feeding structure 2 includes a feeding component 21 and a limiting component 22 disposed on the feeding component 21. The feeding component 21 is used to feed the packaging boxes into the limiting component 22, which in turn limits and transfers the packaging boxes. The feeding component 21 includes several feeding rollers 211 rotatably connected to the base 1 and a feeding belt. The feeding rollers 211 are horizontally arranged, and the feeding belt covers them. The feeding rollers 211 are driven to rotate by a motor. The feeding belt has baffles on both sides. Stacked packaging boxes are placed on the feeding belt, and driven by the feeding rollers 211, the stacked packaging boxes are transported along the feeding belt.

[0028] The limiting component 22 is located on the side of the feeding component 21 near the positioning conveyor structure 3, and has a limiting channel communicating with the positioning conveyor structure 3. In this embodiment, the limiting component 22 includes a limiting connecting seat 221 fixedly connected to the feeding component 21. The upper part of the limiting connecting seat 221 communicates with the feeding belt, and the lower part of the limiting connecting seat 221 communicates with the positioning conveyor structure 3. The limiting connecting seat 221 has limiting side plates 2211 on both sides of its width. The limiting side plates 2211 have folded edges that block and limit the packaging boxes. The two limiting side plates 2211 together form a limiting channel. When the stacked packaging boxes are transported to the limiting connecting seat 221, the packaging boxes fall along the limiting channel of the limiting connecting seat 221 to the positioning conveyor structure 3.

[0029] Reference Figure 3 as well as Figure 4When stacked packaging boxes fall directly along the limiting channel, they are prone to misalignment, affecting subsequent processes. To ensure that the packaging boxes fall normally, the feeding structure 2 also includes a buffer component 23. In this embodiment, the buffer component 23 includes a buffer block 231 disposed below the limiting connecting seat 221 and a buffer driving component 232 for driving the buffer block 231. A through hole is provided below the limiting connecting seat 221, and the buffer block 231 passes through the through hole, so that the buffer block 231 is connected to the limiting channel and slidably connected to the limiting connecting seat 221. The buffer driving component 232 is a buffer cylinder. Under the drive of the buffer cylinder, the buffer block 231 can rise or fall within the limiting channel to support the stacked packaging boxes, so that the packaging boxes move to the bottom of the limiting channel with support. A pushing component is provided on the side of the limiting connecting seat 221 away from the positioning conveying structure 3. The pushing component includes a pushing cylinder and a pushing block. Driven by the pushing cylinder, the pushing block pushes the packaging box out from the bottom of the limiting channel and into the positioning conveying structure 3.

[0030] Reference Figure 4 , Figure 5 as well as Figure 6 The positioning and conveying structure 3 includes a conveying assembly 31, a plurality of positioning components 32 disposed on the conveying assembly 31, and a positioning drive assembly 33 for opening the positioning components 32. Specifically, to accommodate the installation of the conveying assembly 31, a conveying groove is provided on the base 1 along its length. The conveying assembly 31 includes a plurality of conveying rollers 311 rotatably connected to the base 1 and a conveyor belt 312. The plurality of conveying rollers 311 are located in the conveying groove and are arranged along the length of the conveying groove. The conveyor belt 312 covers the plurality of conveying rollers 311. The conveying rollers 311 are driven by a motor, and under the drive of the conveying rollers 311, the conveyor belt 312 drives the plurality of positioning components 32 to move.

[0031] Several positioning components 32 are evenly arranged along the length of the conveyor belt 312. Each positioning component 32 includes a positioning fixture 321 for clamping and fixing the cigarette pack box, and a positioning drive component 33 faces the positioning component 32. Taking a single positioning fixture 321 as an example, a single positioning fixture 321 includes two fixture seats 3211, and there is a cavity between the two fixture seats 3211 for accommodating the cigarette pack box. It is understood that a single positioning fixture 321 has a cavity, and a single positioning fixture 321 can also cooperate with adjacent positioning fixtures 321 to form a cavity.

[0032] To prevent the packaging box from being accidentally inserted and to clamp the packaging box, a first limiting block 3212 and a second limiting block 3213 are provided on opposite sides of the adjacent fixture base 3211. The first limiting block 3212 and the second limiting block 3213 are slidably connected to the fixture base 3211 by springs. The springs apply a force to the first limiting block 3212 and the second limiting block 3213 toward the other side. In the initial state, the first limiting block 3212 and the second limiting block 3213 extend under the action of the springs, blocking the packaging box from entering and preventing the packaging box from being accidentally pushed in.

[0033] Driven by the positioning drive component 33, the first limiting block 3212 and the second limiting block 3213 open to allow the packaging box to be fed in. Specifically, the first limiting block 3212 is clamped at the middle position in the width direction of the packaging box, and is used to position and fix the overall position of the packaging box. The second limiting block 3213 is clamped on both sides in the width direction of the packaging box, one side being the rotating side of the outer cover. The second limiting block 3213 on this side is used to restrict the rotation of the outer cover of the packaging box, thereby preventing the outer cover from being accidentally opened and affecting subsequent processes. Driven by the positioning drive component 33, the first limiting block 3212 and the second limiting block 3213 open, the pusher pushes the packaging box out, and the packaging box is fed between the two positioning fixtures 321. Then, the first limiting block 3212 resets to clamp the packaging box, while the second limiting block 3213 remains open until the subsequent process is completed to limit the outer cover. It can be understood that the number and position of the limiting blocks can be adjusted according to actual needs.

[0034] The positioning drive assembly 33 includes a first positioning drive member 331 and a second positioning drive member 332. The first positioning drive member 331 is a cylinder and has a wedge 3311 facing the first limiting block 3212. The first limiting block 3212 has a first groove, and the wedge 3311 contacts or disengages from the first groove. Driven by the cylinder, the wedge 3311 extends and contacts the first groove, causing the two first limiting members to move away from each other to open. Similarly, the second positioning drive member 332 is a cylinder and has a top block 3321 facing the second limiting block 3213. The second limiting block 3213 has a second groove, and the top block 3321 contacts or disengages from the second groove. Driven by the cylinder, the top block 3321 extends and contacts the second groove, causing the two second limiting blocks 3213 to move away from each other to open and release the limiting of the outer cover.

[0035] In addition, the feeding and positioning mechanism also includes a box opening structure 4, which includes a box opening arm 41 rotatably connected to the base 1 and a box opening drive component for driving the box opening arm 41. The box opening arm 41 is provided with several box opening suction cups, which face the positioning and conveying structure 3. After the packaging box is fixed, the box opening arm 41 drives the several box opening suction cups to approach and contact the outer cover. Then, the box opening suction cups adsorb the outer cover, and the outer cover is opened under the drive of the box opening arm 41. In this embodiment, after the outer cover is opened, the second limiting block 3213 resets and abuts against both sides of the outer cover to apply a holding force to the outer cover. Then, the packaging box is sent to the next station for subsequent processes.
