Description

Technical Field

[0001] This utility model relates to die-cutting machines, and more specifically to a feeding mechanism for a bag-binding machine. Background Technology

[0002] A bag-stacking machine is a specialized piece of equipment used to stack and collect packaging bags before strapping them together. The feeding mechanism is primarily used for stacking and transferring the bags. Traditional feeding mechanisms mainly use a single conveyor belt, which can lead to loosening or misalignment of the stacked bags during actual use, affecting the quality of stacking and transfer. Therefore, some structures with collection boxes for bag stacking and collection have emerged on the market. However, these structures can only accommodate bags of specific sizes; when the bag sizes change, the collection box must be replaced, which is cumbersome. Furthermore, for bags with varying thicknesses at both ends, such as zipper bags, stacking a certain number can cause excessive height differences at the ends, leading to the top bag slipping off and affecting stacking stability. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a feeding mechanism for a bag strapping machine to solve the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A feeding mechanism for a bag-binding machine is characterized by: a crossbar arranged front to back, with pusher columns arranged on the crossbar, the crossbar being connected to a corresponding moving drive component, support bars arranged left to right above the crossbar, the support bars having clearance grooves for the pusher columns to pass through, and partitions arranged at intervals left to right, the partitions being connected to a moving adjustment component, the moving adjustment component being able to adjust the spacing between adjacent partitions, the adjacent partitions on the left and right and the adjacent pusher columns on the front and back together enclosing a placement space for placing, stacking and pushing materials, the cross-section of the support bars being U-shaped.

[0006] The motion drive assembly includes a first chain and a second chain arranged side by side, the first chain passing around a first sprocket and the second chain passing around a second sprocket, with one of the adjacent crossbars located on the first chain and the other on the second chain.

[0007] The first sprocket is connected to the output end of the first motor, and the second sprocket is connected to the output end of the second motor.

[0008] Both the first sprocket and the second sprocket are connected to the drive shaft, which is connected to the drive motor.

[0009] The feeding mechanism of the bag strapping machine described above uses partitions and pusher columns to create a space for stacking and pushing packaging bags. The positions of the partitions and pusher columns can be adjusted to regulate the size of the space, accommodating different sizes of packaging bags and effectively improving its flexibility. Furthermore, by using support bars with a U-shaped cross-section, when placing packaging bags with a thicker end, such as zipper bags, the thicker end of the bag can naturally droop into the groove of the U-shaped support bar, while the remaining portion is supported by the top of the support bar. This ensures the packaging bags are stacked flat and maintains stacking stability. Attached Figure Description

[0015] As shown in the figure, the feeding mechanism of the bag-binding machine disclosed in this utility model includes a crossbar 3 arranged in a front-to-back manner, a pusher column 1 arranged on the crossbar 3, and the crossbar 3 connected to a corresponding moving drive component. Support bars 2 are arranged in a left-to-right manner above the crossbar 3, and the support bars 2 are provided with clearance grooves for the pusher column 1 to pass through. It also includes partitions 9 arranged at intervals on the left and right, and the partitions 9 are connected to a moving adjustment component. The moving adjustment component can adjust the spacing between adjacent partitions 9. The adjacent partitions 9 on the left and right and the adjacent pusher columns 1 on the front and back together enclose a placement space for the placement, stacking and pushing of materials. The cross-section of the support bar 2 is U-shaped.

[0016] Furthermore, the motion drive assembly includes a first chain 4 and a second chain 5 arranged side by side. The first chain 4 passes around a first sprocket 6, and the second chain 5 passes around a second sprocket 7. One of the adjacent crossbars 3 is mounted on the first chain 4, and the other is mounted on the second chain 5. With this structure, by controlling the movement of the first chain 4, one of the adjacent crossbars 3 can be moved, thereby adjusting the distance between the two crossbars 3 to accommodate packaging bags of different sizes.

[0017] Furthermore, the first sprocket 6 is connected to the output end of the first motor, and the second sprocket 7 is connected to the output end of the second motor. With this structure, only the corresponding motor needs to be controlled to move either the first or second chain, thus achieving its movement. Individual chain movement can be controlled separately to adjust the distance between the two crossbars 3, or both chains can be controlled to move simultaneously, thereby achieving synchronous feeding operations.

[0018] Furthermore, both the first sprocket 6 and the second sprocket 7 are connected to the drive shaft 8, which is in turn connected to the drive motor. With this structure, a single motor controls the synchronous movement of the two chains for feeding. When rotation of a single sprocket is required, the connection between that sprocket and the drive shaft 8 can be separated, for example, using a clutch mechanism, thereby controlling the movement of an individual chain. This allows adjustment of the distance between two adjacent crossbars 3 to suit the specifications of the packaging bag.

[0019] Furthermore, the movable adjustment assembly includes a movable frame 10, with each partition 9 mounted on its corresponding movable frame 10. The movable frame 10 is slidably mounted on a guide rail 11 and locked in position by fasteners. With this structure, when the position of the partition 9 needs to be adjusted, the fasteners can be loosened first, and then the movable frame 10 can be slid along the guide rail 11, thereby adjusting the spacing between the partitions 9 to suit the specifications of the packaging bag.

[0020] The working principle of this utility model is as follows: the packaging bags are continuously conveyed by the front conveyor belt assembly and fall into the placement space enclosed by two adjacent partitions 9 and the pusher column 1. As the packaging bags are continuously stacked and collected, if the packaging bag is a zipper bag with one end thicker, the thicker end will naturally hang down into the groove of the U-shaped support bar 2, while the rest is supported by the top of the support bar 2, ensuring that the packaging bag will not slip off due to one end being higher during the stacking process. When the packaging bags are stacked to the required number, the two adjacent crossbars 3 are controlled to move synchronously, so that the pusher column 1 pushes the stacked packaging bags backward to the next work station.
