Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, specifically a container bag sealing machine. Background Technology

[0002] In the operation of a FIBC (Flexible Intermediate Bulk Container) sewing machine, the edge pressing device plays an indispensable role. It is responsible for pressing the fabric edges tightly during the sewing process, ensuring that the sewing thread can evenly and firmly sew the fabric together, thereby guaranteeing the stitch strength and appearance quality of the FIBC.

[0003] However, the existing edge-pressing devices of FIBC (Flexible Intermediate Bulk Container) sewing machines generally have certain limitations. These devices typically only press the edge on one side of the needle tip, which significantly restricts the application range of the sewing machine. In actual production, different customers have different requirements for FIBC sewing. Some require simultaneous edge pressing and sewing on both sides of the FIBC to enhance its overall sealing and strength; while in the production of some specially designed FIBCs, only one edge needs to be pressed. Existing single-sided edge-pressing devices cannot flexibly meet these diverse needs, leading companies to often need to change different types of sewing machines when faced with different orders, increasing production costs and the complexity of equipment management. Therefore, it is necessary to design a FIBC sewing machine to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a container bag sewing machine to solve the problems mentioned in the background art.

[0006] A set of pressure-edge components fixedly connected to the bracket;

[0007] Another set of edge-pressing components is slidably connected to the aforementioned fixed edge-pressing components. The two sets of edge-pressing components arranged in a mirror image together constitute an adjustable edge-pressing device. By adjusting the two sets of edge-pressing components, they can be located on both sides of the needle tip to perform edge pressing on both sides, or they can be located on one side of the needle tip to perform edge pressing on one side.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please refer to Figure 1-4 As shown, this utility model provides a container bag sewing machine, including a sewing machine head 1 and a set of brackets 2 assembled at the lower end of the sewing machine head 1;

[0025] A set of clamping components fixedly connected to bracket 2;

[0026] Another set of edge-pressing components is slidably connected to the aforementioned fixed edge-pressing components. The two sets of edge-pressing components arranged in a mirror image together constitute an adjustable edge-pressing device. By adjusting the two sets of edge-pressing components, they can be located on both sides of the needle tip to perform edge pressing on both sides, or they can be located on one side of the needle tip to perform edge pressing on one side.

[0027] A locking component that works in conjunction with a limiting element to fix the slidably connected edge clamping element in the desired position, thereby determining the working state of the edge clamping device.

[0028] This adjustable edge presser mainly consists of two sets of edge presser components. One set is fixedly connected to the bracket 2, and the other set is slidably connected to the fixed edge presser component. By moving the slidably connected edge presser component relative to the fixed edge presser component, the positional relationship between the two sets of edge presser components can be changed. When edge pressing on both sides is required, the two sets of edge presser components are adjusted to be located on both sides of the sewing machine needle; when edge pressing on one side is required, the two sets of edge presser components are adjusted to be located on the same side of the needle. Using a locking component and a limiting component, when the slidably connected edge presser component moves to the desired position, the locking component fixes it, thereby determining the working state of the edge presser and ensuring the stability of the edge presser component position during sewing.

[0029] By adjusting the positions of the two sets of edge-pressing parts, two different working modes, namely edge pressing on both sides and edge pressing on one side, can be achieved, meeting the needs of different sewing processes for edge pressing methods and improving the versatility and applicability of the equipment.

[0030] Specifically, the limiting component includes a transmission rod 3 and a connecting plate 4. Each end of the slidably connected pressing edge component is connected to a set of transmission rods 3. The two sets of transmission rods 3 penetrate another pressing edge component fixed to the bracket 2 and are movably connected to the connecting plate 4. The connecting plate 4, in conjunction with the locking component, locks the position of the slidably connected pressing edge component. The transmission rod 3 is a cross-shaped structure, which can realize the synchronous transmission of the two pressing edge components. The locking component includes a slide block 5, a slide rod 6, a bolt 7, and a positioning hole 8. A set of slide blocks 5 is integrally formed on one side of the connecting plate 4. The slide block 5 is slidably connected to the slide rod 6 installed on one side of the bracket 2. A set of bolts 7 is threaded onto the slide block 5. The bolts 7 can be inserted into the positioning holes 8 opened in the slide rod 6. Two sets of positioning holes 8 are opened, each corresponding to a different locking position.

[0031] When the slidably connected pressing element is pulled, the transmission rod 3 slides along a fixed set of pressing elements, allowing adjustment of pressing elements on both sides or one side. Since the transmission rod 3 is a cross-shaped structure, it enables synchronous transmission of the two sets of pressing elements. After the pressing element is adjusted to the desired position, the threaded bolt 7 on the slide block 5 is rotated, causing the bolt 7 to insert into the positioning hole 8 on the slide rod 6. Two sets of positioning holes 8 are provided, each corresponding to a different locking position, thus locking the slidably connected pressing element in different positions, such as pressing elements on both sides or one side.

[0032] The transmission rod 3 adopts a cross-shaped structure, which can ensure that the two sets of pressing parts can achieve synchronous transmission. The slide rod 6 has two sets of positioning holes 8, which correspond to different locking positions. According to the actual sewing needs, the operator can quickly and conveniently lock the pressing parts in the position of pressing on both sides or one side by rotating the bolt 7 into different positioning holes 8, which improves the flexibility of operation.

[0033] The pressing component includes a limiting plate 9, a transmission wheel 10, a transmission belt 11, and a limiting roller 12. Each end of the limiting plate 9 is equipped with a set of rotatable transmission wheels 10. The two sets of transmission wheels 10 are connected by the transmission belt 11. The two sets of transmission wheels 10 are respectively connected to two sets of transmission rods 3. The side of the limiting plate 9 facing the inner ring of the transmission belt 11 is rotatably connected to multiple sets of limiting rollers 12. The limiting rollers 12 are used to ensure that the transmission belt 11 remains stable during operation, so that the transmission belt 11 can stably play the pressing effect.

[0034] During the sewing process, as the FIBC moves, it drives the transmission belt 11 to rotate, which in turn drives the transmission wheel 10 to rotate. This, in conjunction with the transmission rod 3, ensures that the two sets of edge-pressing components operate synchronously. The transmission belt 11 contacts the FIBC, utilizing the friction between them to press the edge. Because the transmission belt 11 is rotatable, it does not affect the movement of the FIBC with the sewing machine while pressing the edge. During the operation of the transmission belt 11, the limit roller 12 contacts and rolls with the inner ring of the transmission belt 11, ensuring the transmission belt 11 remains stable during operation and consistently provides the edge-pressing effect. Through the cooperation of the transmission wheel 10, the transmission belt 11, and the transmission rod 3, the synchronous operation of the two sets of edge-pressing components is achieved, ensuring the coordination and consistency of the edge-pressing operation and improving the edge-pressing quality.

[0035] By utilizing the rotatable characteristics of the transmission belt 11, the movement of the FIBC (Flexible Intermediate Bulk Container) with the sewing machine is not affected when pressing the edge of the FIBC. This meets the actual needs of both pressing the edge and moving the FIBC during the sewing process. The limiting roller 12 is rotatably connected to the limiting plate 9 and contacts the inner ring of the transmission belt 11, which can effectively ensure the stability of the transmission belt 11 during operation and prevent the transmission belt 11 from shaking or deviating. This ensures the stability and reliability of the pressing effect and improves the quality of the sewn products.

[0036] Working principle: When the slidable edge-pressing component is pulled, the transmission rod 3 slides along a fixed set of edge-pressing components, allowing adjustment of the edge-pressing on both sides or one side. Once the edge-pressing component is adjusted to the desired position, the threaded bolt 7 on the slide block 5 is rotated, causing the bolt 7 to insert into the positioning hole 8 on the slide rod 6. Two sets of positioning holes 8 are provided, each corresponding to a different locking position, thus locking the slidable edge-pressing component in different positions, such as edge-pressing on both sides or one side. During sewing, as the container bag moves, it drives the transmission belt 11 to rotate, which in turn drives the transmission wheel 10 to rotate, coordinating with the transmission rod 3 to adjust the two sets of edge-pressing components. The edge pressing components operate synchronously, with the transmission belt 11 contacting the FIBC (Flexible Intermediate Bulk Container). Utilizing the friction between the transmission belt 11 and the FIBC, the edge pressing effect is achieved. Since the transmission belt 11 is rotatable, it does not affect the movement of the FIBC with the sewing machine while pressing the edge. During the operation of the transmission belt 11, the limiting roller 12 contacts and rolls with the inner ring of the transmission belt 11, ensuring the transmission belt 11 remains stable during operation and guaranteeing a stable edge pressing effect. Through the cooperation of the transmission wheel 10, the transmission belt 11, and the transmission rod 3, the synchronous operation of the two sets of edge pressing components can be achieved, ensuring the coordination and consistency of the edge pressing operation and improving the edge pressing quality.
