Description

Technical Field

[0001] The utility model belongs to the technical field of wine packaging box preparation, and relates to an anti-scratch structure 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 great gravity, and the high friction force 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 printed surface of the bottom of the packaging paper shell is in contact with the rough surface of the next layer of packaging paper shells. During the friction and pulling process of the belt, it is also easy to cause slight scratches. Summary of the invention

[0005] Furthermore, the above-mentioned anti-scratch structure for a wine box packaging paper feeder also includes a layer of flexible cloth arranged on the crossbeam at one end of the output of the friction feeding belt machine.

[0017] 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 pushing mechanism 1 is installed on a pushing base 4. The left end of the pushing base extends into a frame 5, and the right end is placed outside the frame 5 for a distance.

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.

[0018] 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 spaced 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 studs pass through the bottom plate 401 and are fixed with double nuts, which can adjust the height of the support legs.

The belt drive mechanism 807 drives the vertical sliding plate 805 to move up and down. The synchronous belt 808 of the vertical synchronous belt drive mechanism 807 is sleeved on two synchronous pulleys 809. The two synchronous pulleys 809 are rotatably connected to the side walls of the frame 5 through bearing seats.

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. The second cantilever rod 801 adopts a round rod with a conical head at the end, which is convenient for extending into the bottom of the stacked packaging paper shells supported by the third cantilever rod for transitional support.
