[0002] Currently, non-woven fabric is widely used in the market for food packaging, such as flour. It offers good sealing and is less prone to leakage compared to woven bags. However, the structural strength of non-woven fabric is lower than that of woven bags.

[0003] Most non-woven packaging bags currently use heat sealing, which is fast and efficient for both the bottom and the sides of the bag.

[0004] However, when heat sealing is used on the sides of non-woven fabric, its structural strength is difficult to meet the stacking requirements of packaged products. For example, when used as flour bags, there is a limit to the number of heat-sealed non-woven packaging bags that can be stacked. If the number is too high, the heat-sealed edges of the bottom non-woven bags will be crushed.

[0005] Therefore, it is necessary to use sewing to sew the left and right sides of the non-woven fabric.

[0006] Currently, there is no sewing device specifically designed for the left and right sides of non-woven packaging bags. Summary of the Invention

[0026] The specific details of this utility model are further described below:

[0027] This utility model relates to a stacking and arranging device for the sewing process of non-woven packaging bags, such as... Figure 1 The device shown includes a bag receiving mechanism, a conveying mechanism, a sewing mechanism, a stacking bag arrangement device, and a display rack.

[0028] The bag receiving mechanism is used to transfer the slit and folded non-woven packaging bags sent by the material conveyor to the conveying mechanism. The sewing mechanism hooks onto the conveyor to sew the two sides of the non-woven packaging bags. When the conveying mechanism transports the non-woven packaging bags to the end, the stacking bag-swinging device transfers the non-woven packaging bags to the bag-swinging frame.

[0029] Specifically, the bag receiving mechanism of this device is located on the side of the incoming material conveyor, and its structure is as follows: Figure 3 As shown, it includes a gripper 1, a gripping arm 2, a bag-grabbing cylinder 3, a moving frame 4, and a bag-receiving frame 5. The gripper 1 is located at the lower end of the gripping arm 2. The gripper 1 is driven by the bag-grabbing cylinder 3 to grip non-woven packaging bags. The gripping arm 2 is located on the moving frame 4, and the moving frame 4 is located on the bag-receiving frame 5. The bag-receiving frame 5 is located above the conveying mechanism and the incoming material conveyor.

[0030] Conveying mechanisms such as Figure 1 As shown, the system includes a bottom conveyor 6 and an upper conveyor 7, separated by a distance equal to the thickness of the non-woven bag. The front end of the bottom conveyor 6 is longer than that of the upper conveyor 7, and the widths of the upper conveyor 7 and the bottom conveyor 6 are smaller than the width of the non-woven bag. The sewing mechanism consists of two sets, respectively located on both sides of the conveyor, for sewing the two sides of the non-woven bag. The sewing mechanism is an existing device, with a wire cutting device at the rear to cut the sewing threads of the non-woven packaging bags, which are still connected in series, for further stacking.

[0031] The stacked bag device of this apparatus is as follows: Figure 2 The device shown is located at the lower part of the outlet end of the conveying mechanism and includes a swing bag grid plate 8, a swing shaft 9, and a swing drive. The swing bag grid plate 8 is fixed on the swing shaft 9, and the swing shaft 9 is provided with a swing drive at its end.

[0032] The swing frame is set as a planar structure, located below the rear end of the stacked bag device, at a height lower than the swing axis 9, for stacking and arranging the sewn non-woven packaging.

[0033] Specifically, the bottom conveyor 6 in this device is lower than the incoming material conveyor. The bottom conveyor 6 includes a front roller 61, a rear roller 62, a support plate 63, and a bottom conveyor belt 64. The support plate 63 is located between the front roller and the rear roller 62, and is positioned below the conveyor belt to support the middle of the support belt.

[0034] Specifically, the upper conveyor 7 in this device includes front and rear rollers 71 and a lower conveyor belt 72. A lower pressure plate is provided between the front and rear rollers 71. The lower pressure plate is connected to the upper conveyor 7 frame by a spring. The front and rear rollers 71 are set on the upper conveyor 7 frame.

[0035] Specifically, in this device, the upper conveyor 7 is symmetrically arranged with the same structure on the left and right sides. At the end of each upper conveyor 7, there is an anti-sticking plate 73. The front end of the anti-sticking plate 73 is horizontally fixed on the upper conveyor 7 frame and parallel to the lower part of the lower conveyor belt 72. The rear end is curved upwards towards the rear end.

[0036] Among them, the bag rack plate 8 in the stacked bag racking device is a rectangular frame with a rack structure inside, and the upper part is bent towards the conveyor belt.

[0037] The swing drive of this device is a gear rack and cylinder mechanism, including a driven gear 11, a rack 12 and a swing cylinder 13 mounted on the swing shaft 9. The cylinder is vertically fixed to the front end of the receiving mechanism. The rack 12 is mounted at the front end of the piston rod of the cylinder. The gears mesh with each other. The cylinder action drives the rack 12 to move up and down and mesh with the driven gear 11.

[0038] The working process of this device is as follows: In the bag receiving mechanism of this device, the gripper moves on the moving frame 4 to the upper part of the incoming material conveyor, grabs the non-woven packaging bag on the incoming material conveyor, and then moves it to the bottom conveyor of the conveying mechanism. It enters the space between the bottom conveyor and the upper conveyor with the conveyor. During this process, the sewing machine sews the two sides of the non-woven packaging bag and cuts the sewing thread after sewing.

[0039] As the anti-stick plate falls, when it reaches the bag-swinging grid plate 8, the swing drive operates, causing the bag-swinging grid plate 8 to swing downwards onto the placement frame, and the non-woven packaging bag falls onto the placement frame, completing the sewing process of one non-woven packaging bag.

[0040] This invention sews the two sides of the non-woven packaging bag, which improves the strength of the non-woven packaging bag and makes it suitable for stacking. The feeding machine in this device adopts automated equipment to ensure the automation of the sewing process and high processing efficiency.
