Description

Technical Field

[0001] This utility model relates to the field of packaging bag manufacturing technology, specifically to a packaging bag misalignment device. Background Technology

[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags end up in landfills like regular waste, with only 7% being recycled.

[0003] Packaging bags all have sealing strips, which are quite thick, usually several times the thickness of the packaging bag. Therefore, when many packaging bags are neatly stacked, the sealing strips will greatly increase the overall thickness of the packaging bags, making it inconvenient for packing and transportation. Currently, the packaging bags are usually moved along the length direction so that the sealing strips are staggered, thereby reducing the overall thickness when packing. The same box can hold more packaging bags. However, manual methods are inefficient and not conducive to actual production. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a packaging bag misalignment device to solve the problem that the sealing strip will increase the overall thickness when packaging bags are stacked and packed in the prior art.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please see Figures 1 to 7 This embodiment provides a packaging bag misalignment device, comprising two side baffles 1, a first baffle 2, a second baffle 3, and a driving unit 4.

[0026] The two side baffles 1 are arranged along the first direction and block the packaging bag along the thickness direction. The packaging bag misalignment device also includes a fixing plate 6, and both side baffles 1 are connected to the fixing plate 6. Specifically, the fixing plate 6 has two sets of first oblong holes 6a along the first direction. The two sets of first oblong holes 6a are respectively used to connect the two side baffles 1. The distance between the two side baffles 1 can be adjusted along the first oblong holes 6a, so as to accommodate different numbers of packaging bags.

[0027] The first baffle 2 and the second baffle 3 are arranged along a second direction, which is perpendicular to the second direction. Both the first baffle 2 and the second baffle 3 have limiting portions 5. The limiting portions 5 are not perpendicular to the second direction at any point on their cross-section, and the limiting portions 5 of the first baffle 2 and the second baffle 3 are parallel. The driving unit 4 is connected to the second baffle 3 to drive the second baffle 3 to move along the second direction. When the driving unit 4 drives the second baffle 3 to move, the distance between the first baffle 2 and the second baffle 3 decreases, and the second baffle 3 pushes the packaging bag to move, causing the packaging bags to stagger, thus causing the sealing strips on the packaging bags to stagger, thereby preventing the protruding sealing strips from greatly increasing the thickness of the packaging bag inside the box. Therefore, the shape of the limiting portion 5 can be arbitrary, such as wavy or oblique. In this embodiment, the first baffle 2 has a "<" shaped cross-section, and the second baffle 3 has a "W" shaped cross-section. The extended portions on both sides can prevent the packaging bag from falling off the sides. Preferably, the driving unit 4 is a cylinder, which is convenient for installation and control.

[0028] Preferably, the packaging bag misalignment device further includes a lead screw module 7, which is fixed to the side of the fixing plate 6 away from the side baffle 1. The first baffle 2 and the second baffle 3 are both fixed to the moving end of the lead screw module 7. The lead screw module 7 is used to adjust the distance between the first baffle 2 and the second baffle 3, thereby making the device suitable for packaging bags of different lengths. Specifically, the lead screw module 7 includes a lead screw 7a, fixing blocks 7b, a first slider 7c, and a second slider 7d. The two fixing blocks 7b are fixed to the fixing plate 6. The lead screw 7a is arranged along a second direction and its two ends are rotatably connected to the two fixing blocks 7b respectively. The first slider 7c and the second slider 7d are threadedly connected to the lead screw 7a. The first slider 7c is fixedly connected to the first baffle 2, and the second slider 7d is fixedly connected to the drive unit 4. Further, the lead screw 7a is a positive and negative lead screw 7a. The first slider 7c and the second slider 7d are respectively threadedly connected to the positive and negative threads of the positive and negative lead screw 7a. Therefore, when the lead screw 7a is rotated in one direction, the movement of the first slider 7c and the second slider 7d is opposite. Preferably, the fixing plate 6 has a second oblong hole 6b along the second direction. The first slider 7c and the first baffle 2, as well as the second slider 7d and the drive unit 4, are fixedly connected by connecting posts. The second oblong hole 6b is used to avoid the connecting posts. The connecting posts can be designed with bolts and long washers, which can fix the first slider 7c and the first baffle 2, as well as the second slider 7d and the drive unit 4, without fixing the first slider 7c, the first baffle 2, the second slider 7d, and the drive unit 4 to the fixing plate 6. Therefore, it will not hinder the movement of the first slider 7c and the second slider 7d along the lead screw 7a.

[0029] The packaging bag misalignment device also includes a material picking component 8 and a robotic arm 9. The material picking component 8 includes a linear drive unit 8a, a rotating unit 8b, and a picking rack 8c. The rotating unit 8b is fixed to the moving end of the linear drive unit 8a, and the picking rack 8c is fixed to the moving end of the rotating unit 8b. The linear drive unit 8a adopts a linear module, and the rotating unit 8b can adopt a rotary cylinder. The picking rack 8c holds packaging bags, and the direction of the packaging bags can be rotated according to actual packaging needs. The robotic arm 9 is used to transfer the material in the picking rack 8c to between the first baffle 2 and the second baffle 3.

[0030] Preferably, the lead screw module 7 further includes a fixing bolt 7e, which is threadedly connected to the fixing block and abuts against the lead screw 7a. It can be used to fix the lead screw 7a and restrict its rotation. When the distance between the first slider 7c and the second slider 7d is adjusted to a suitable level, the fixing bolt 7e is turned to abut against the lead screw 7a, thus restricting the rotation of the lead screw 7a and fixing the first slider 7c and the second slider 7d.

[0031] Preferably, the two side baffles 1 are flared outwards in a direction that moves away from each other, which facilitates the insertion of the packaging bag from above the side baffles 1. A clearance opening is also provided on the upper part of the side baffles 1, which facilitates the robotic arm 9 above to grasp the packaging bag in the two side baffles 1.

[0032] In summary, the packaging bag misalignment device provided by this utility model uses a driving unit 4 to drive the second baffle 3 to move, so that multiple packaging bags between the two side baffles 1 are staggered. Therefore, the sealing strips on adjacent packaging bags are also staggered, which greatly reduces the overall thickness of the packaging bags, facilitates packing and transportation, has a simple overall structure, and uses a mechanical structure to replace manual operation, which greatly improves work efficiency.

[0033] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
