Description

Technical Field

[0001] The utility model relates to the field of sewing bag devices, in particular to a multi-needle feed mill sewing bag device. Background Art

[0002] In the process of feed production, efficiently and accurately sealing feed packaging bags is a crucial link. It not only directly affects the packaging quality and appearance neatness of the feed, but also serves as the cornerstone for ensuring that the feed is protected from contamination and maintains stable and safe quality during storage and transportation.

[0003] However, traditional methods for sealing feed packaging bags mostly use manual sewing or simple mechanical sealing equipment, which have many deficiencies. Firstly, manual sewing is not only inefficient, but also difficult to guarantee the sealing quality, and problems such as thread shedding and missed sewing are likely to occur, affecting the storage and transportation of the feed. Secondly, although simple mechanical sealing equipment improves the sealing efficiency to a certain extent, due to the lack of precise guiding and limiting structures, the sealing position is often inaccurate and the sealing quality is unstable.

[0004] Therefore, in view of the situation where the traditional methods for sealing feed packaging bags mostly use manual sewing or simple mechanical sealing equipment, resulting in difficult-to-guarantee sealing quality, a multi-needle feed mill sewing bag device can be designed. Through a double-stitching design and the addition of a guiding and limiting structure, not only the firmness and stability of the stitching are improved, but also the stitching quality of the seal is guaranteed. Summary of the Utility Model

[0005] In order to overcome the problem that the traditional methods for sealing feed packaging bags mostly use manual sewing or simple mechanical sealing equipment, resulting in difficult-to-guarantee sealing quality.

[0006] The technical solution of the utility model is as follows: A multi-needle feed mill sewing bag device, including a conveyor, support feet, a sewing machine, a fixing plate, a round rod, a guiding plate, a lifting component, a first needle and a second needle; four support feet for support are fixedly connected to the lower end of the conveyor, two fixing plates are symmetrically fixedly connected to the left and right of the rear end of the conveyor, a round rod is fixedly connected to the front end of each fixing plate, a guiding plate is fixedly connected to the front end of the round rod, a lifting component is installed at the rear end of the conveyor and is located between the two fixing plates, a sewing machine is installed in the lifting component, a first needle and a second needle are symmetrically installed up and down in the sewing machine, and the first needle is located above the second needle.

[0007] Preferably, the conveyor transports the bags filled with feed to the designated bag sewing position. The feet are important components for supporting the conveyor, ensuring that the device can be stably placed on the ground. The fixed plate provides an installation basis for the subsequent guide plate. The round rod plays a connecting role. It is connected to the front end of the fixed plate and provides support for the guide plate. The guide plate is used to guide the direction of the bag during transportation, making the sewing opening neater. The lifting component is responsible for adjusting the height and position of the bag sewing machine to adapt to bags of different sizes. The bag sewing machine is responsible for sewing the mouth of the bag. The bag sewing machine adopts advanced sewing technology and an automated control system, capable of achieving high-speed and precise sewing operations. The first stitch and the second stitch are important components on the bag sewing machine, responsible for passing the thread through the mouth of the bag and sewing it up. Through the up-and-down symmetric installation method, double stitching of the bag mouth can be achieved, thereby improving the firmness and stability of the stitching.

[0008] Preferably, a column is fixedly connected to the rear end of the conveyor. A through groove is opened at the front end of the column. A circular hole groove is penetrated through the inner wall of the upper end of the through groove. The column not only provides an additional support structure but also provides a basis for the installation of the subsequent rotary motor, threaded rod, and lifting component. The through groove provides space for the installation of the threaded rod and the lifting seat. The through groove ensures that the threaded rod can rotate smoothly within the through groove. At the same time, a circular hole groove is penetrated through the inner wall of the upper end of the through groove, providing a position for the upper end of the threaded rod to pass through and be fixed, ensuring that the threaded rod can be connected to the output shaft of the rotary motor.

[0009] Preferably, a rotary support seat is fixedly connected to the bottom of the through groove, and a rotary motor is installed at the upper end of the column. The rotary support seat provides a rotary support point for the threaded rod, ensuring that the threaded rod can rotate smoothly therein. The rotary motor provides the power to drive the rotation of the threaded rod.

[0010] Preferably, a threaded rod is rotatably connected within the rotary support seat. A coupling is installed at the upper end of the threaded rod and is connected to the output shaft of the rotary motor through the coupling. The threaded rod is a component connecting the rotary support seat and the lifting seat. It realizes the lifting function through cooperation with the internal thread within the lifting seat. The coupling is a component connecting the output shaft of the rotary motor and the upper end of the threaded rod, and it transmits the power of the rotary motor to the threaded rod.

[0011] Preferably, the lifting component includes a lifting seat and a cross plate; an internal thread adapted to the external thread of the threaded rod is provided within the lifting seat, and the threaded rod is threadedly connected within the lifting seat. A cross plate is fixedly connected to the front end of the lifting seat. The lifting seat is the main part of the lifting component, and it realizes the lifting function through cooperation with the internal thread of the threaded rod. The cross plate is a component fixed to the front end of the lifting seat, and it provides connection points with subsequent components, such as the bag sewing machine.

[0012] Preferably, a first limiting plate is fixedly connected to the front end of the cross plate. The upper end of the first limiting plate is fixedly connected to one end of the connecting plate, and the other end of the connecting plate is fixedly connected to the upper end of the second limiting plate. The second limiting plate is located in front of the first limiting plate. The first limiting plate is fixedly connected to the cross plate and together with the second limiting plate forms a guiding gap, which plays a role in restricting the sealing position of the feed packaging bag. The connecting plate is a bridge connecting the first limiting plate and the second limiting plate, and it plays a role in fixing the second limiting plate.

[0013] Preferably, a guiding gap is provided between the first limiting plate and the second limiting plate. The seal of the feed packaging bag is adapted to the guiding gap and passes through the guiding gap. The guiding gap is a space jointly formed by the first limiting plate and the second limiting plate, which allows the seal of the feed packaging bag to pass through and be restricted. This design helps to ensure the stability and accuracy of the seal during the sealing process.
