Description

Technical Field

[0001] The utility model belongs to the technical field of wine packaging box preparation, and relates to a lifting mechanism for a wine box packaging paper feeding machine. Background Art

[0002] Wine box packaging paper shell (such as Figure 1 The box structure is formed by multiple bending and bonding of corresponding equipment. After the existing wine box packaging paper shells are stacked, they are manually fed into the feed port before entering the equipment. The pushing process uses a bottom belt to push the bottom packaging paper shells one by one (the front end is blocked by a limit baffle to leave a gap for a packaging paper shell). In this feeding process, too much stacking causes the bottom to be subjected to heavy gravity, and the high friction can easily cause scratches. The problem can be solved by using the bottom of the stacked packaging paper shells to press against the friction feeding belt to realize feeding. However, the vertical slide feeding process is located under the belt conveyor, which is not convenient for unloading. Using a pushing mechanism to feed the material in is easy to interfere with the pushing mechanism. Summary of the invention

[0016] Example 1: Reference Figure 1-Figure 6As shown, a lifting mechanism for a wine box packaging paper feeder includes a cantilever rod 3 201, a vertical sliding plate 202, a vertical slider guide rail pair 203 and a vertical synchronous belt drive mechanism 204. The cantilever rod 3 201 adopts multiple rods, and the left end is evenly fixedly connected to the vertical sliding plate 202 at the front and back ends and is staggered with the cantilever rod 1 101 and the cantilever rod 2 801. The front and rear ends of the vertical sliding plate 202 are both provided with a mounting sliding plate 205 facing the cantilever rod 1 101 side. Each mounting sliding plate 205 is connected to the frame 5 through the vertical slider guide pair 203 and driven by the vertical synchronous belt driving mechanism 204 to move the sliding plate 205 up and down. Two symmetrical vertical synchronous belt driving mechanisms 2 are used. The synchronous belt has an elastic buffering effect. When the stacked packaging paper shells are in contact with the belt of the friction feeding belt machine, the relative elasticity of the two can avoid the effect of excessive squeezing of the stacked packaging paper shells. The lifting and lowering cantilever rod 3 is controlled and kept staggered with the cantilever rod 1, so that the lifting and lowering can be realized. At the same time, it avoids interference with the cantilever rod 1, and the starting position of the cantilever rod 3 is lower than the cantilever rod 1, which is convenient for feeding the stacked packaging paper shells into the lifting mechanism. Multiple cantilever supports are lifted and lowered, and the lifting is stable and reliable. The belt drive has fast transmission and synchronous belt drive, and the lifting height accuracy is easy to control. The synchronous belt 206 of the vertical synchronous belt drive mechanism 204 is sleeved on the two synchronous belt pulleys 207. The two synchronous belt pulleys 207 are rotatably connected to the side wall of the frame 5 through the bearing seat. The inner side of the synchronous belt 206 The section is fixedly connected to the side of the installed sliding plate 205 by a pressure plate and screws to drive it to move up and down along the vertical slider guide pair 203. The pressure plate presses the belt against the side of the installed sliding plate and then locks it with screws. One of the synchronous pulleys 207 is connected to the lifting drive motor 208, and the lifting drive motor 208 is fixedly connected to the side wall of the frame 5. The slider of the vertical slider guide pair 203 is fixedly connected to the side of the installed sliding plate 205, and the guide rail of the vertical slider guide pair 203 is fixedly connected to the side wall of the frame 5.

[0017] The lifting mechanism is provided with a limit baffle 13 on both sides near the top, and the limit baffle 13 can realize the limitation of the stacked packaging paper shells. The limit baffle 13 on one side is arranged in multiple intervals, and the limit baffle 13 is fixedly connected to the connecting plate 14. The connecting plate 14 is fixedly connected to the horizontal vertical beam 12 by a screw 15 and a double nut 16. The screw 14 passes through the two sides of the horizontal vertical beam 12 and is locked by two nuts 16 respectively, so as to realize the telescopic position adjustment of the limit baffle 1 to meet the requirements of different sizes of packaging paper shells. The bottom end of the limit baffle 13 is inclined outward to play a guiding role, so as to facilitate the directional feeding of the lifted and stacked packaging paper shells to the bottom of the friction feeding belt machine 3.

[0018] Example 2: Reference Figure 1-Figure 6As shown, a wine box packaging paper feeding machine includes a pushing mechanism 1, a lifting mechanism 2 and a friction feeding belt conveyor 3.

The lifting mechanism 2 is installed on the frame 5 and located at the left end of the pushing base 4. The fed packaging paper shells 6 are fed upward to the feeding mechanism 3. The friction feeding belt conveyor 3 is installed on the frame 5 and located at the upper end of the lifting mechanism 2. The friction feeding belt conveyor 3 feeds the packaging paper shells 6 one by one to the feeding double belt conveyor 7 under the support and cooperation of the lifting mechanism 2. The feeding port also includes a transition lifting mechanism 8 installed in the frame 5. The transition lifting mechanism 8 is located on the right side of the lifting mechanism 2 and above the pushing base 4. It is used to extend and lift the packaging paper shell 6 fed by the lifting mechanism 2 to the friction feeding belt conveyor 3 for temporary support. The automatic pushing mechanism, lifting mechanism and friction feeding belt conveyor are used for top pushing. Only the non-printing surface of the packaging paper shell on the top is directly in contact with the friction feeding belt mechanism for delivery. There is no possibility of scratching the printed surface due to the influence of gravity generated by stacking. The transition lifting mechanism can realize continuous feeding without generating idle beats, thereby improving production efficiency. Moreover, the feeding end can be set lower to avoid time-consuming and labor-intensive feeding caused by being too high.

[0019] The pushing mechanism 1 comprises a cantilever rod 101, a horizontal sliding plate 102 and a horizontal slider guide pair 103.

The pushing base of this structure has stable and reliable support, and the connecting rods 402 are evenly arranged at intervals and lower than the cantilever rod 1, which can also play a role in reinforcing the bottom plate to avoid weak support rigidity due to its thinness. Multiple rows of universal wheels 405 and multiple rows of support legs 406 are arranged on the front and rear sides of the bottom of the bottom plate 401, and the support legs 406 are provided with a conical chassis and studs.

The transition structure matches the transition support function very well, and will not interfere with the action of the lifting mechanism. In addition, two symmetrical vertical synchronous belt drive mechanisms 807 are adopted. The synchronous belt has an elastic buffering effect. When the stacked packaging paper shells contact the belt of the friction feeding belt machine, the relative elasticity of the two can avoid the effect of transitional squeezing of the stacked packaging paper shells.
