Description

Technical Field

[0001] This utility model relates to the field of case packing machine technology, and in particular to a soft bag case packing machine. Background Technology

[0002] In modern industrial production, case packers, as key equipment in automated packaging processes, play a crucial role in efficiently and systematically packing products into boxes, and are widely used in numerous industries such as food, pharmaceuticals, and chemicals. Flexible bags, as a common form of product packaging, are widely used for packaging various granular, powdery, and liquid products due to their soft material, high plasticity, and low cost. After production, flexible bags need to be inserted into the interior of packaging boxes.

[0003] Currently, when soft bags are continuously packed into packaging boxes, due to their softness, the bags tend to pile up loosely and not tightly, resulting in insufficient use of packaging box space, increased transportation costs, and difficulty in removing the boxes from under the conveyor belt and replacing them with new ones after they are full. This leads to low packing continuity and affects overall packing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of loose stacking and inconvenience in changing packaging boxes when packing soft bags into packaging boxes in the existing technology, and to propose a soft bag packing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soft bag packing machine includes a housing, a conveyor belt, and a packaging box. The housing has an inlet adapted to the conveyor belt, and the outlet end of the conveyor belt is inserted into the inlet. Two partitions are fixedly connected inside the housing, and the space between the two partitions is a storage area. The left side of the left partition is the upper box area, and the right side of the right partition is the lower box area. The storage area, the upper box area, and the lower box area are all adapted to the packaging box. A bag pressing mechanism is provided inside the storage area. A storage box frame is fixedly connected inside the upper box area, and a box pushing mechanism is provided below the storage box frame.

[0007] Preferably, the bag-pressing mechanism includes a first electric push rod fixedly installed on the top wall inside the housing, and a bag-pressing plate is installed on the telescopic end of the first electric push rod, and the bag-pressing plate is slidably disposed inside the storage area.

[0008] Preferably, a baffle plate is fixedly connected to the upper surface of the bag pressing plate, and the upper surface of the baffle plate slides through the shell.

[0009] Preferably, the box-pushing mechanism includes a support plate fixedly connected to the back of the housing, a second electric push rod fixedly installed on one side of the support plate, a sliding plate fixedly connected to the telescopic end of the second electric push rod, a sliding groove for the sliding plate to slide horizontally opened inside the housing, a box-pushing plate fixedly connected to the front of the sliding plate, and the box-pushing plate slidably connected inside the upper box area.

[0010] Preferably, a baffle plate for blocking the bottom opening of the storage box frame is fixedly connected to the left side of the push box plate.

[0011] Preferably, two feed plates are fixedly connected inside the housing.

[0012] Compared with the prior art, the present invention provides a soft bag packing machine, which has the following beneficial effects.

[0013] 1. This utility model, by setting up a bag-pressing mechanism, can drive the bag-pressing plate to periodically press down on the soft bags inside the packaging box, thereby effectively compacting the loosely piled soft bags inside the packaging box. This significantly reduces the space waste caused by the soft nature of the soft bags and reduces transportation costs. At the same time, the bag-blocking plate can descend synchronously during the bag-pressing operation, forming a physical block on the bags waiting to fall at the end of the conveyor belt, preventing additional bags from falling into the packaging box during the bag-pressing process and interfering with the compaction effect, thus ensuring the stability and reliability of the bag-pressing operation.

[0014] 2. Through the coordinated design of the box pushing mechanism and the storage box frame, this utility model can push the full box from the storage area to the lower box area after the packaging box is filled and the bag is pressed, and push the packaging box in the upper box area to the storage area. At the same time, the baffle plate blocks the bottom opening of the storage box frame to ensure that the boxes to be packed in the storage box frame will not slip off prematurely during the box pushing process, thereby effectively improving the packing efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A soft bag packing machine includes a housing 1, a conveyor belt 2, and a packaging box 5. The housing 1 has an inlet 3 adapted to the conveyor belt 2, and the outlet end of the conveyor belt 2 is inserted into the inlet 3. Two partitions 4 are fixedly connected inside the housing 1, with a storage area between the two partitions 4. The left side of the left partition 4 is the upper box area, and the right side of the right partition 4 is the lower box area. The storage area, upper box area, and lower box area are all adapted to the packaging box 5. Two feed plates 15 are fixedly connected inside the housing 1, and the two partitions 4 divide the interior of the housing 1 into... The system consists of three independent functional areas: a storage area, which is the main packing area for soft bags; an upper box area, which stores empty boxes to be packed; and a lower box area, which temporarily stores full boxes 5. This three-zone structure enables spatial partitioning of the packing process, facilitating the orderly execution of automated operations. The feed plate 15 is fixedly installed inside the housing 1 and located below the bag inlet 3. Its rounded corner structure at the top forms a smooth transition with the discharge end of the conveyor belt 2, which can guide the soft bags to fall accurately into the boxes 5 in the storage area along the rounded corner trajectory, reducing the problem of bag displacement or uneven stacking caused by right-angle collisions.

[0023] The storage area is equipped with a bag-pressing mechanism, which includes a first electric push rod 7 fixedly installed on the top wall of the housing 1. A bag-pressing plate 8 is installed on the telescopic end of the first electric push rod 7 and is slidably disposed inside the storage area. The bag-pressing plate 8 is rectangular flat and its size matches the cross-section of the storage area. Wear-resistant rubber strips are provided on the edges to reduce friction loss with the inner wall of the packaging box 5 during the pressing process and improve the bag-pressing effect. When the soft bags in the storage area accumulate to a preset height, the control system triggers the first electric push rod 7 to descend, driving the bag-pressing plate 8 to compact the bags.

[0024] A bag-blocking plate 9 is fixedly connected to the upper surface of the bag-pressing plate 8, and the upper surface of the bag-blocking plate 9 slides through the housing 1. The bag-blocking plate 9 is a vertically arranged long strip plate with a width consistent with the width of the conveyor belt 2. When the first electric push rod 7 drives the bag-pressing plate 8 to descend and press the bag, the bag-blocking plate 9 descends synchronously, and its top end is higher than the upper surface of the conveyor belt 2, forming a physical block on the bag body to be dropped on the conveyor belt 2, preventing the new bag body from falling into the packaging box 5 during the bag-pressing process, and ensuring the independence and effectiveness of the bag-pressing operation. When the bag pressing is completed and the first electric push rod 7 is reset, the bag-blocking plate 9 rises synchronously to a position lower than the upper surface of the conveyor belt 2, releasing the blocking state and allowing the bag body to continue to fall into the packaging box 5.

[0025] A storage box frame 6 is fixedly connected inside the upper box area. A box pushing mechanism is provided below the storage box frame 6. The box pushing mechanism includes a support plate 10 fixedly connected to the back of the housing 1. A second electric push rod 11 is fixedly installed on one side of the support plate 10. A sliding plate 12 is fixedly connected to the telescopic end of the second electric push rod 11. A sliding groove is provided inside the housing 1 for the sliding plate 12 to slide horizontally. A box pushing plate 13 is fixedly connected to the front of the sliding plate 12. The box pushing plate 13 is slidably connected inside the upper box area. The storage box frame 6 is a rectangular frame structure with an open top. Multiple packaging boxes 5 can be stacked inside. The size of the bottom opening matches the bottom surface of the packaging box 5 to ensure that empty boxes can be dropped one by one onto the storage area.

[0026] A baffle plate 14 is fixedly connected to the left side of the pusher plate 13 to block the bottom opening of the storage box frame 6. The baffle plate 14 is a horizontally set plate with a length consistent with the width of the bottom opening of the storage box frame 6. When the pusher plate 13 moves to the right to push out a full box, the baffle plate 14 will block the bottom opening of the storage box frame 6, preventing the empty box in the storage box frame 6 from falling. When the pusher plate 13 is in the initial state, the bottom opening of the storage box frame 6 will be exposed, and the empty box at the bottom of the storage box frame 6 will fall to the top of the storage area under the action of gravity.

[0027] Once the packaging box 5 is full and finally compacted, the second electric push rod 11 extends, driving the sliding plate 12, the pusher plate 13, and the baffle plate 14 to move horizontally to the right. The pusher plate 13 pushes the full box from the storage area to the right to the lower box area for temporary storage, and pushes the empty box to the storage area. At the same time, the baffle plate 14 moves with the pusher plate 13, blocking the bottom opening of the storage box frame 6 and preventing the empty box in the storage box frame 6 from falling. When the full box is completely pushed out to the lower box area, the second electric push rod 11 retracts and resets, and the baffle plate 14 exposes the bottom opening of the storage box frame 6. The empty box at the bottom of the storage box frame 6 falls to the top of the storage area under the action of gravity, and enters the next round of packing cycle.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
