Description

Technical Field

[0002] Some scattered materials (such as candies, snacks, etc.) need to be boxed after production for subsequent transportation, storage and sales. However, currently, most of these materials need to be boxed manually, which increases the workload and has a relatively low boxing efficiency.

[0003] In order to solve this problem, in some existing technologies, the materials are packed into boxes through a feeding device, which includes a storage mechanism, a discharge mechanism and a guide mechanism. The guide mechanism is arranged vertically, and the outlet of the guide mechanism faces downward. When the box body on the conveyor belt passes under the guide mechanism, the discharge mechanism discharges the materials in the storage mechanism, and the materials are loaded into the box body through the guide mechanism. In order to ensure the efficiency of box loading, the conveyor belt needs to keep running. Since the discharge speed of the discharge mechanism is slow, in a single discharge process, the box body has passed the outlet of the guide mechanism, and the materials have not been fully discharged, causing part of the materials to fall on the conveyor belt. For this reason, the conveyor belt can only be paused to make the material box still, and the conveyor belt can be started again after the loading is completed, thereby reducing the box loading efficiency.

[0036] like Figures 1 to 4As shown, the bulk material boxing device provided by the utility model can automatically follow the box body 4 to be loaded for a distance so that the material 1 completely falls into the box body 4 to be loaded, thereby realizing automatic boxing. The bulk material boxing device includes a frame (not shown in the figure), a feeding mechanism 2, a transmission mechanism (not shown in the figure) and a driving mechanism 3. The feeding mechanism 2 includes a discharge member 21 and a guide member 22. The discharge member 21 is arranged on the frame. The discharge member 21 has a discharge outlet. The feed end of the guide member 22 is connected to the discharge outlet. The transmission mechanism is arranged below the feeding mechanism 2 and is used to transfer the box body 4 to be loaded; the driving mechanism 3 is arranged on the frame and is used to drive the discharge end of the guide member 22 to reciprocate between the first position and the second position, and in the process of the discharge end moving from the first position to the second position, the opening of the discharge end is opposite to the opening of the box body 4 to be loaded. Among them, the first position and the second position are respectively the two extreme positions of the reciprocating motion of the discharge end of the guide member 22. Specifically, when the box body 4 to be loaded on the conveying mechanism passes below the first position of the discharge end, the discharge member 21 performs a discharge operation, and in the process of the box body 4 to be loaded moving from below the first position of the discharge end to below the second position, the discharge end moves from the first position to the second position, and the opening of the discharge end is always facing the opening of the box body 4 to be loaded, and then the material 1 enters the box body 4 to be loaded from the discharge end of the guide member 22. In this process, the opening of the discharge end is always facing the opening of the box body 4 to be loaded, which improves the box loading efficiency and prevents the material 1 from falling outside the box body 4 to be loaded.

[0037] Optionally, the frame includes a base and a stand, the base is arranged on one side of the transmission mechanism, the driving mechanism 3 is fixed on the base, the stand is arranged on the other side of the transmission mechanism, and the material discharge member 21 is fixed on the stand. Optionally, the transmission mechanism includes a transmission drive member and a transmission member, the transmission drive member can be a motor, and the transmission member can be a belt, which is driven by the motor to rotate the belt to transmit the box body 4 to be loaded.

[0038] Optionally, in the present embodiment, the cross-sectional area of ​​the guide member 22 gradually decreases from the feed end to the discharge end to ensure the smooth falling of the material 1. Of course, in other embodiments, the cross-sectional area of ​​the guide member 22 may be the same from the feed end to the discharge end, which is not limited to the present embodiment. In addition, the opening of the discharge end of the guide member 22 is directly opposite to the opening of the box body 4 to be loaded, and the opening area of ​​the discharge end of the guide member 22 is smaller than the opening area of ​​the box body 4 to be loaded, which ensures that the material 1 will not fall on the transmission mechanism. Optionally, in the present embodiment, the guide member 22 is a prismatic structure. Of course, in other embodiments, the guide member 22 may also be a conical structure or an irregular structure, which is not limited to the present embodiment.

[0039] Optionally, in this embodiment, the discharge member 21 is fixed on the frame, the feed end of the guide member 22 is rotatably connected to the discharge member 21, and the driving mechanism 3 is used to drive the discharge end of the guide member 22 to swing back and forth between a first position and a second position. The first position and the second position are two swing limit positions of the discharge end of the guide member 22, respectively. Through the rotation of the feed end of the guide member 22 and the discharge member 21, and the swing of the discharge end of the guide member 22, the opening of the discharge end is always aligned with the opening of the box body 4 to be loaded, and the structure is simple. When the box body 4 to be loaded is transmitted to the bottom of the first position of the discharge end by the transmission mechanism, the box body 4 to be loaded starts to be loaded, and when the box body 4 to be loaded is transmitted to the bottom of the second position of the discharge end by the transmission mechanism, the box body 4 to be loaded completes the loading. In addition, the discharge piece 21 can also be slidably connected to the frame, and the feed end of the guide piece 22 is fixedly connected to the discharge piece 21. The discharge end of the guide piece 22 is driven by the driving mechanism 3 to move back and forth linearly between the first position and the second position, so that the opening of the discharge end is always facing the opening of the box body 4 to be loaded.

In the process of transmitting the box body 4 to be loaded along the first direction X, the discharge member 21 discharges the box body 4 to be loaded, and the discharge end of the guide member 22 swings from the first position to the second position. When the discharge end of the guide member 22 swings to the second position, the loading of the box body 4 to be loaded is completed. Afterwards, the discharge end of the guide member 22 swings from the second position to the first position. Since there is a preset distance between any two adjacent box bodies 4 to be loaded, when the discharge end of the guide member 22 swings back to the first position, the adjacent second box body 4 to be loaded is transferred to this position, and then the adjacent second box body 4 to be loaded is unloaded, thereby realizing continuous unloading of multiple box bodies 4 to be loaded, avoiding the stop of the conveying mechanism, and ensuring that the material 1 does not fall on the conveying mechanism.
