Description

Technical Field

[0001] The utility model relates to the technical field of bag edge folding, in particular to a bag edge folding device. Background Art

[0002] A packaging bag refers to a bag used for packaging various articles, which facilitates the transportation of goods during the production and circulation process and is easy to store. It is widely used in daily life and industrial production. Actual figures show that 80% of the plastic bags after use are finally transported to the landfill for disposal like ordinary garbage, and only 7% of the plastics are recycled. Among them, when plastic packaging bags are subjected to edge folding treatment, due to their current difficult folding, a folding device is used for cooperation during the packaging of plastic packaging bags.

[0003] For example, a Chinese patent with the publication number CN213769203U discloses a bag edge folding device, including a fixed base. Both ends of the fixed base are fixedly connected with support plates. A groove is fixedly arranged on the support plate on the left side of the fixed base. The top of the support plate on the left side of the fixed base is threadedly connected with a first threaded rod. The first threaded rod extends into the groove in a threaded manner. The top of the first threaded rod is fixedly connected with a rotation knob. The bottom end of the first threaded rod is rotatably connected with a first pressing plate. A second threaded rod is rotatably connected to the support plate on the left side of the fixed base. The other end of the second threaded rod penetrates through the support plate on the right side of the fixed base and extends to the right side. In this application, the first threaded rod drives the pressing plate to press the leftmost side of the packaging bag. The moving plate drives the second pressing plate to rise, and the spring is compressed, so that the other end of the packaging bag passes through the fixed cavity on the sliding plate. The moving plate is lowered, and the elastic force of the spring drives the spring to return to its original state. The second pressing plate presses down to press the packaging bag, thereby fixing the packaging bag.

[0004] Although the above-mentioned bag edge folding device can perform the edge folding of the packaging bag, this edge folding device does not have a bag mouth alignment structure, cannot connect the bag surfaces of the packaging bag, the bag mouth is relatively loose, and the edge folding effect is poor. Therefore, this application provides a bag edge folding device to meet the requirements. Summary of the Utility Model

[0041] In the embodiment of the present utility model, the objects loaded into the packaging bags can be loaded through the receiving hoppers 7 on the bottom plate 1. By pulling the connecting plates 3, the distance between the adapter pieces 4 and the bottom plate 1 can be adjusted, facilitating the edge folding of packaging bags of different heights. And through the clamping of the width of the bag edges on the clamping and folding pieces, the edge folding width of the packaging bags can be adjusted, increasing the edge folding flexibility of the edge folding device. Through the heating treatment of the bag surfaces of the packaging bags by the sealing and heating seats 6, the two bag surfaces can be heated and melted to realize the connection of the bag surfaces, increasing the firmness of the bag mouth.

[0042] As Figures 1 to 5 shown, chutes 101 are opened on both sides of the receiving hoppers 7 on the bottom plate 1. A support seat 8 is fixedly connected to one end of the bottom plate 1 away from the connecting plates 3. Through the opening of the chutes 101, the sliding range of the extension rods 2 on the bottom plate 1 can be set.

[0043] Further, sliding blocks 201 matched with the chutes 101 are fixedly connected to the extension rods 2. Through the use of the sliding blocks 201, it is convenient for the extension rods 2 to move in the chutes 101, and further, the distance between the connecting plates 3 and the bottom plate 1 can be adjusted to realize the edge folding of packaging bags of different heights, and the edge folding width of the packaging bags can be adjusted.

[0044] Further, the adapter piece 4 includes a rotating seat 401 arranged on the connecting plate 3 and a rotating shaft 402 rotatably connected to the rotating seat 401. The rotating shaft 402 is fixedly connected to the clamping and folding piece 5. Through the adapter piece 4, it is convenient to rotate the use angle of the clamping and folding piece 5 for folding the bag edges of the packaging bags.

[0045] Furthermore, the clamping folding part 5 includes a folding plate A501 connected to the adapter 4, a pad 502 arranged on the folding plate A501, two elastic plates 503 arranged on the folding plate A501, and a same clamping plate 504 connected to the two elastic plates 503. By using the clamping folding part 5, it is convenient to clamp and align the bag mouth of the packaging bag, which is used for the alignment of the two bag edges and the clamping of bag edges of different widths.

[0046] Furthermore, the elastic plate 503 is U-shaped, and one end of the elastic plate 503 is fixedly connected to the folding plate A501. The elastic plate 503 is an elastic alloy. By setting the elastic plate 503, it is convenient to pry the clamping plate 504 apart from the folding plate A501, so that the edge of the packaging bag can be placed through the gap, and then the edge of the packaging bag can be clamped by loosening the clamping plate 504.

[0047] Furthermore, the clamping plate 504 is U-shaped, and the width of the clamping plate 504 is the same as that of the folding plate A501. The clamping plate 504 is located on the opening side of the containing bucket 7, and can heat and fix the clamped edge of the packaging bag.

[0048] Furthermore, the sealing heating seat 6 includes a folding plate B602 arranged in the middle of the seat body and a heating plate 601 arranged at the upper end of the folding plate B602.

The heating plate 601 is powered on and heated, so that the bag surface of the packaging bag can be heated to achieve sealing and fixation of the bag opening.

[0049] When the embodiment of the present utility model is in use, first place the bottom plate 1 horizontally through the receiving hopper 7 and the support seat 8. Then, put one end of the packaging bag for storing objects into the receiving hopper, and place the bag mouth end of the packaging bag on the clamping and folding member 5. By pulling the connecting plate 3, the slider 201 on the extension rod 2 slides in the chute 101, and the outer side of the connecting plate 3 is adjusted to the folded edge of the packaging bag. Then, open the clamping plate 504, open the clamping plate 504 from the folding plate A 501, align the bag edge of the packaging bag, and place it under the clamping plate 504. Then, loosen the clamping plate 504 to clamp and fix the bag edge. Then, through the rotational connection of the rotating seat 401 and the rotating shaft 402 on the adapter 4, the folding plate B 602 can be rotated towards the sealing and heating seat, and the bag edge of the packaging bag is folded towards the bag surface along with the folding plate B 602. Then, operate the sealing and heating seat 6 through the control button 901 on the controller 9, so that the heating plate 601 is energized and heated to heat the bag surface of the packaging bag. After the bag surface of the packaging bag is heated and melted, and by pressing down the folding plate B 602, the bag surfaces are connected. Then, release the folding plate B 602, and take out the packaging bag from the receiving hopper 7, thus completing the edge folding work of the packaging bag. Through the adjustment of the distance between the connecting plate 3 and the bottom plate 1 and the edge folding setting of the bag edge on the clamping plate 504, the flexibility of the edge folding device is increased; when the edge folding device is used vertically, the edge folding device can be vertically placed through the support seat 8 and the receiving hopper 7, and then the above steps can be applied to perform edge folding treatment on the packaging bag and achieve the sealing and fixing of the bag mouth, improving the use effect of the edge folding device and having practicality.

[0050] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
