[0001] The utility model relates to the technical field of flexible intermediate bulk container production devices, and specifically, to a sewing device for flexible intermediate bulk container production. Background Art
[0002] Flexible intermediate bulk containers are a widely used packaging material. Flexible intermediate bulk containers can effectively prevent goods from being damaged or contaminated during transportation and storage. Since flexible intermediate bulk containers are light, soft, and easy to stack, they can be conveniently transported and handled. At the same time, flexible intermediate bulk containers can be reused by refilling clean substances, thus reducing the impact on the environment. During the production process of flexible intermediate bulk containers, the bag body material is folded, and sealing treatment is performed from three directions of the folded bag body, leaving only one bag opening. With the development of technology, the existing production of flexible intermediate bulk containers mostly relies on sewing devices.
[0003] During the sewing process of the bag body material, in order to enhance the sealing performance of its side ends and bottom, the edges of the bag body need to be hemmed, and then the sewing device is used to stitch the hems together. However, during the production process of flexible intermediate bulk containers, according to the need, manual operation is required. When pushing the bag body towards the sewing machine, the hem is prone to reset. The processing personnel need to always press the edge of the bag body, which is not only inconvenient to operate but also may cause hand injuries to the processing personnel due to operation errors. For this reason, a sewing device for flexible intermediate bulk container production is proposed, and the hems at the edges of the bag body are pressed by the pressure rollers inside the two groups of clamping jaws to solve the above problems. Summary of the Utility Model
[0004] The utility model provides a sewing device for flexible intermediate bulk container production, which solves the problems that the hem is prone to loosen during the sewing process of the flexible intermediate bulk container, affecting the production effect of the flexible intermediate bulk container, and the hand of the staff is injured due to improper operation.
[0005] The technical solution of the utility model is as follows:

Specific embodiments
[0023] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.
[0024] Embodiment 1
[0025] As Figures 1 to 2 shown, a sewing device for producing flexible intermediate bulk containers includes a sewing table 1. The top of the sewing table 1 is symmetrically and slidably connected with a top plate 2. The top of the top plate 2 is fixedly connected with a sewing machine 3. The top of the top plate 2 is provided with an edge pressing assembly 4. The edge pressing assembly 4 includes a mounting plate 401 fixedly connected to the top of the top plate 2. A card slot 402 is opened on one side of the mounting plate 401. A fixing plate 403 is fixedly connected inside the card slot 402. Claws 405 are symmetrically and rotatably connected to both ends of the mounting plate 401. A pressing roller 406 is rotatably connected inside the claw 405. The purpose of this setting is that before sewing the bag body, the bag body is first folded, and both sides of the folded bag body are respectively passed through the groove between the mounting plate 401 and the fixing plate 403, and the edges of the folded bag body are hemmed. Two sets of claws 405 and the pressing rollers 406 inside them are used to press both sides of the folded bag body respectively. During the sewing process, it is not necessary for the processing personnel to always press the hemmed part of the bag body by hand, which can prevent the hemmed part from loosening and affecting the sewing effect of the bag body, and at the same time avoid the phenomenon of injury caused by improper operation of the processing personnel.
[0026] Preferably, the fixing plate 403 is U-shaped. The upper and lower sides of the inner cavity of the card slot 402 and both ends of the fixing plate 403 are straight. The edge pressing assembly 4 further includes folding rollers 404 rotatably connected to both sides of the inner cavity of the card slot 402 and both ends of the fixing plate 403. The purpose of this setting is that the provided folding rollers 404 can press and limit the edge of the hemmed bag body. At the same time, the provided folding rollers 404 and pressing rollers 406 facilitate the movement of the folded bag body towards the sewing machine 3 during the processing, and accelerate the sewing speed of the flexible intermediate bulk container.
[0027] Preferably, the edge pressing assembly 4 further includes a torsion spring 407 symmetrically and fixedly connected between the mounting plate 401 and the claw 405. The purpose of this setting is that the elastic force generated by the torsion spring 407 enhances the pressing force of the claw 405 and the pressing roller 406 inside it on the folded edge of the bag body, preventing the folded edge from restoring and affecting the sewing effect of the flexible intermediate bulk container.
[0028] Embodiment 2
[0029] As Figures 1 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that sliding grooves 5 are symmetrically opened at the top end of the sewing table 1, and there are two sliding grooves 5 in each group. Side plates 6 are symmetrically and fixedly connected to the bottom end of the top plate 2, and the side plates 6 are slidably connected to the inside of the sliding grooves 5. A stud 7 is fixedly connected between the two side plates 6, and a screw rod 8 is threadedly connected between the two studs 7. Lower clamping plates 9 are symmetrically and fixedly connected to one side of the sewing table 1, and a lower guide roller 10 is rotatably connected between the two lower clamping plates 9. The purpose of this setting is that the provided sliding grooves 5 facilitate adjusting the distance between the two sewing machines 3, so as to facilitate free adjustment according to the width of the folded bag body. During the adjustment process, rotate the screw rod 8. Since the screw rod 8 is connected to the stud 7 in a threaded connection manner, and the two threads at the outer end of the screw rod 8 are arranged in opposite directions, when the screw rod 8 is rotated, the two sewing machines 3 move towards or away from each other.
[0030] Preferably, upper clamping plates 11 are symmetrically and fixedly connected to the top end of the sewing table 1. A connecting groove 12 is opened on the outer surface of the upper clamping plate 11. A connecting rod 13 is slidably connected to the inside of the connecting groove 12. An upper guide roller 14 is rotatably connected between the two connecting rods 13. The lower guide roller 10 corresponds to the position of the upper guide roller 14. A support rod 15 is fixedly connected to the inside of the connecting groove 12, and the support rod 15 is slidably connected to the connecting rod 13. The purpose of this setting is that the provided lower guide roller 10 and upper guide roller 14 also have the effect of pressing and limiting the folded bag body, and at the same time can make the bag body flat, preventing the flexible intermediate bulk container after sewing from having wrinkles and affecting the use effect of the flexible intermediate bulk container.
[0031] Preferably, a compression spring 16 is sleeved on the outer end of the support rod 15, and the compression spring 16 is fixedly connected between the top end of the connecting groove 12 and the connecting rod 13. The purpose of this setting is that the provided compression spring 16 enhances the pressing force of the lower guide roller 10 and the upper guide roller 14 on the folded bag body.
[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
