Description

Technical Field

[0001] This utility model relates to the field of plastic bag production technology, and in particular to an automatic stacking and bundling device for plastic bags. Background Technology

[0002] Currently, bag-making machines on the market all use manual binding at the end, which is very costly and inefficient. With social progress and rapid technological development, the speed of bag-making machines has increased from producing dozens or hundreds of bags per minute to producing 200 or more bags per minute. The traditional manual binding method can no longer keep up with the speed of bag-making machines, which seriously affects the production efficiency of packaging bags. Therefore, there is an urgent need for automated equipment that can automatically bind plastic bags to replace manual binding. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes an automatic stacking and bundling device for plastic bags produced by a bag making machine, which automatically stacks, sorts and bundles the bags, thereby improving work efficiency.

[0004] To solve this technical problem, the present invention adopts the following solution: an automatic stacking and bundling device for plastic bags, comprising a frame, a controller, a conveying mechanism and a bundling mechanism mounted on the frame, wherein the input end of the conveying mechanism is connected to the bag outlet of a plastic bag making machine, and the bundling mechanism is located at the outlet of the conveying mechanism to bundle the stacked plastic bags and then send them out; the device also includes a first support plate, a second support plate, a first receiving mechanism and a second receiving mechanism, wherein the first support plate and the second support plate are spaced apart on the frame above the conveying mechanism, and the first receiving mechanism and the second receiving mechanism are respectively located at the upper and lower parts between the first support plate and the second support plate; each of the first receiving mechanism and the second receiving mechanism includes a first drive unit and a second drive unit. The unit comprises a first receiving plate and a second receiving plate. The first driving unit is mounted on the first support plate and its output end is connected to and drives the first receiving plate to reciprocate toward the second support plate. The second driving unit is mounted on the second support plate and its output end is connected to and drives the second receiving plate to reciprocate toward the first support plate. The first receiving plate and the second receiving plate of the first receiving mechanism are on the same horizontal plane and symmetrically arranged between the first support plate and the second support plate. The first receiving plate and the second receiving plate of the second receiving mechanism are on the same horizontal plane and symmetrically arranged between the first support plate and the second support plate. The conveying mechanism, the binding mechanism, the first receiving mechanism, and the second receiving mechanism are all connected to and controlled by a controller.

[0005] Further improvements include a first pushing mechanism and a second pushing mechanism. The first pushing mechanism is mounted on the frame and its output end is connected to and drives the first support plate to move horizontally toward the second support plate or to move the first support plate horizontally away from the second support plate. The second pushing mechanism is mounted on the frame and its output end is connected to and drives the second support plate to move horizontally toward the first support plate or to move the second support plate horizontally away from the first support plate. Both the first pushing mechanism and the second pushing mechanism are connected to and controlled by a controller.

[0006] Further improvements include a lifting lever mechanism, which is located on the frame at the middle of the outlet of the conveying mechanism. The lifting lever mechanism blocks and sorts the plastic bags conveyed by the conveying mechanism, and then rises to send the stacked plastic bags conveyed by the conveying mechanism to the binding mechanism for binding.

[0007] In a further improvement, the lifting lever mechanism includes a third drive unit, a lever, and a bracket. The bracket is mounted on the frame, and the third drive unit is connected to and drives the lever to move up and down.

[0008] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By setting a first support plate and a second support plate spaced apart on the conveying mechanism, and setting a first receiving mechanism and a second receiving mechanism respectively at the upper and lower parts between the first support plate and the second support plate, initially, the first driving unit and the second driving unit of the first receiving mechanism respectively control the first receiving plate and the second receiving plate to move to the middle to form a first-layer platform for placing finished plastic bags, so that the first receiving mechanism can receive individual finished plastic bags produced by the bag-making machine. After receiving a single finished product, the first driving unit and the second driving unit of the first receiving mechanism immediately control the first receiving plate and the second receiving plate to move simultaneously towards the first support plate and the second support plate, so that the single finished product falls smoothly onto the second-layer platform formed by the first receiving plate and the second receiving plate of the second receiving mechanism, where the plastic bags are counted and stacked. When the second... When the plastic bags on the second-layer platform, composed of the first and second receiving plates of the receiving mechanism, reach a set quantity, the first and second drive units of the second receiving mechanism respectively control the first and second receiving plates to move simultaneously toward the first and second support plates, causing the stacked plastic bags to fall onto the conveying mechanism as a finished product. The conveying mechanism then transports the stacked finished plastic bags to the binding mechanism for automatic binding and delivery. This achieves automatic stacking, sorting, and binding of plastic bags produced by the bag-making machine, improving work efficiency. Through further settings, the first and second pushing mechanisms allow users to adjust the distance between the first and second support plates according to the size and width of the plastic bags, making it more convenient to use. The lifting lever mechanism allows the stacked plastic bags to be sorted and neatly arranged, resulting in a more even and neat overall appearance of the bound plastic bags, which can be widely promoted and applied.
