[0002] During the production of plastic bags, the finished plastic bags need to be folded for subsequent transportation and storage. At the same time, the folded plastic bags are sold as a whole unit. When folding the plastic bags, a common structure is to set up multiple sets of cylinder drives to drive the folding plates to lift, move horizontally, and fall respectively to achieve the folding of the plastic bags. The process is relatively cumbersome and prone to failure. Utility Model Content
[0003] The technical problem to be solved by the present invention is to address the above-mentioned technical deficiencies and provide a plastic bag folding mechanism, which adopts a curved slide to guide the movement of the folding plates on both sides, and further realizes the folding of the plastic bag by the folding plates under the drive of a single driving mechanism, thereby reducing the driving mechanism, simplifying the equipment operation process, reducing the equipment cost, and reducing the failure rate.

[0005] To further optimize the technical solution, the slide groove includes a flat groove arranged on a side close to the folding station; and a downward-inclined lifting groove arranged on a side away from the folding station; the flat groove and the lifting groove are connected.
[0006] To further optimize this technical solution, a transition plate is provided on the frame for horizontal sliding; the driving mechanism is connected to the folding plate through the transition plate; the driving mechanism drives the folding plate to slide in the slide groove through the transition plate; and a longitudinal groove is provided on the transition plate for the folding plate to slide up and down.
[0007] To further optimize this technical solution, a buffer column is provided on the transition plate at the lower side of the folding plate; a buffer groove is provided on the folding plate corresponding to the buffer column; when one end of the folding plate is slidably arranged at the bottom of the lifting groove, the buffer column and the buffer groove correspond in position.
[0008] To further optimize the technical solution, the frame is provided with a first slide rail for the transition plate to slide horizontally; the transition plate is slidably arranged on the first slide rail.
[0009] To further optimize the technical solution, a second slide rail is provided on the transition plate in parallel with the longitudinal groove; and the folding plate is slidably provided on the second slide rail.
[0010] To further optimize this technical solution, the driving mechanism is a cylinder.
[0011] Compared with the existing technology, the utility model has the following advantages: the folding plate is driven to slide in the slide groove by the driving mechanism, thereby converting the unidirectional movement of the driving mechanism into sliding along the bent slide groove, realizing the folding process and simplifying the operation process; through the longitudinal groove set on the transition plate, this structure advantageously ensures the stability of the equipment operation while sliding horizontally.

[0019] Combine Figure 1-4 As shown, when in use, in the initial state, the folding plate 5 is slidably set in the lifting groove 8, and the folding plate 5 is roughly flush with the middle folding station 2. The plastic bag is sent to the folding station 2, and the two sides of the plastic bag are placed on the folding plate 5. The driving mechanism 6 is extended to make the folding plates 5 on both sides slide from the lifting groove 8 to the flat groove 7 respectively. During the sliding process, the end of the cylinder 13 drives the transition plate 9 to slide horizontally, and further passes through the longitudinal groove 10 of the transition plate 9 to achieve the lateral push of the folding plate 5, so that the folding plate 5 Slide longitudinally along the longitudinal groove 10 to slide from the lifting groove 8 to the flat groove 7. At the same time, during the sliding process, the transition plate 9 slides horizontally along the first slide rail 11 to make the movement process more stable, and the folding plate 5 slides along the second slide rail 12 to make the lifting process more stable. When the plastic bag falls flat on the folding station 2, the folding plates 5 on both sides are roughly flush to ensure that the plastic bag is placed flat. Then, after the pressing plate mechanism 3 presses down the middle of the plastic bag, the two sides of the plastic bag are further lifted up by the folding plates 5 in turn and folded onto the folding station 2.
