[0001] The utility model relates to the field of container bag processing, and specifically relates to a container bag sling sewing machine. Background Technique

[0002] A container bag (also known as a ton bag, flexible container, FIBC) is a large flexible container used for packaging, transporting and storing bulk materials, and is widely used in industries such as chemical industry, building materials, food, and minerals. The container bag mainly consists of a bag body and multiple slings. During the production process of the container bag, it is necessary to sew the slings to the bag body, which requires the use of a container bag sewing machine.

[0003] When the existing container bag sewing machine sews the slings, the fixing effect on the slings is poor, and the slings are prone to deformation. In this way, the sewing thread will also move out of position, which will affect the use of the container bag. Moreover, different slings have different widths, and the positions where the sewing thread is required are also different.

[0004] Therefore, it is necessary to design a new type of container bag sling sewing machine to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a container bag sling sewing machine to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A container bag sling sewing machine, including a sewing machine body, on which there is a support plate in a "C" shape. On the support plate, there is a positioning strip for supporting the container bag sling. Inside the positioning strip, there is an activity cavity. On both sides of the positioning strip, there are pressure rods for pressing the sling and the container bag respectively. Inside the activity cavity, there is an adjustment component.

[0007] Preferably, the adjustment component includes two sliders slidably arranged inside the activity cavity. The sliders are fixedly connected to the pressure rods. Between the two sliders, there is a telescopic component.

[0008] Preferably, the telescopic component includes a rotating shaft arranged inside the activity cavity. On the rotating shaft, there is a first gear fixedly arranged. On the opposite sides of the two sliders, there are racks respectively. The two racks are arranged in a staggered manner and are parallel to each other. The first gear meshes with the two racks.

[0009] Preferably, on the rotating shaft, there is a second gear. Inside the positioning strip, there is an adjustment cavity. On the adjustment cavity, there is an inserted tooth connected by a spring. The inserted tooth meshes with the second gear.

[0010] Preferably, on one side of the positioning strip, there is a pull rod connected to the inserted tooth.

[0011] Preferably, at the bottom of the positioning strip, there are multiple convex strips.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, a pressure plate is set on the support plate, and pressure rods are provided on both sides of the pressure plate. The position of the pressure rods can limit the sewing position, and the sewing position will be determined according to the position of the pressure rods. This avoids large errors in the sewing line during the sewing process between the straps and the container bag, making the sewing process more stable. The position of the pressure rods can be adjusted to accommodate the sewing of straps of various sizes. Attached Figure Description

[0022] Example 1

[0023] Please refer to Figure 1-5As shown in the figure, the utility model provides a sewing machine for container bag slings, including a sewing machine body 1. A support plate 2 in a "C" shape is provided on the body 1. A positioning strip 3 for supporting the container bag slings is provided on the support plate 2. An activity cavity 4 is provided inside the positioning strip 3. Pressure rods 5 for pressing the slings and the container bag are provided on both sides of the positioning strip 3 respectively. An adjusting component is provided inside the activity cavity 4. The adjusting component includes two sliders 6 slidably arranged inside the activity cavity 4. The sliders 6 are fixedly connected to the pressure rods 5. A telescopic component is provided between the two sliders 6.

[0024] The body 1 is a commonly used sewing machine on the market for processing container bags. The support plate 2 is fixedly connected to the body 1. The positioning strip 3 can press the container bag and the sling from top to bottom. The activity cavity 4 is opened inside the positioning strip 3. The pressure rods 5 are located on both sides of the positioning strip 3. There are two sliders 6. The two sliders 6 are respectively fixedly connected to the two pressure rods 5. The two sliders 6 can move towards each other, can adjust the position of the pressure rod 5 according to the sewing position, and can facilitate the limitation of the sewing position.

[0025] Specifically, the telescopic component includes a rotating shaft 7 arranged inside the activity cavity 4. A first gear 8 is fixedly provided on the rotating shaft 7. Rack teeth 9 are respectively provided on the opposite sides of the two sliders 6. The two rack teeth 9 are arranged in a staggered manner and are parallel to each other. The first gear 8 meshes with the two rack teeth 9. The rotating shaft 7 is rotatably connected to the middle of the activity cavity 4. The first gear 8 is fixedly connected to the rotating shaft 7. The rack teeth 9 are fixedly connected to the sliders 6. The two rack teeth 9 are meshed with the first gear 8 together. The rotation of the first gear 8 can drive the two pressure rods 5 to move through the sliders 6, facilitating the adjustment of the position of the pressure rods 5.

[0026] Among them, a second gear 10 is provided on the rotating shaft 7. An adjustment cavity 11 is provided inside the positioning strip 3. A plug tooth 13 connected by a spring 12 is provided on the adjustment cavity 11. The plug tooth 13 meshes with the second gear 10. A pull rod 14 connected to the plug tooth 13 is provided on one side of the positioning strip 3. The second gear 10 is fixedly connected to the rotating shaft 7.
