Description

Technical Field

[0001] The utility model belongs to the technical field of woven bag production, and particularly relates to a sewing device for plastic woven bags. Background Technique

[0002] Plastic woven bags are a common packaging material. In production, the raw materials are melted and plasticized in an extruder and then extruded from the machine head to form a film. After cooling, slitting, heat stretching, heat setting and other processes, flat filaments are made. The flat filaments are woven into cloth by a circular loom or a flat loom, and can be coated or laminated as required. The woven cloth is sewn into a bag with an adhesive or a sewing thread. During production, when sewing a woven bag, a sewing device is needed for sewing. However, it still has the following disadvantages in actual use:

[0003] 1. When sewing a plastic bag, the woven bag is directly conveyed to the sewing position through a conveying structure. During the conveying process, it is easy to cause deviation between the sewing end of the woven bag and the sewing position, affecting the sewing accuracy of the woven bag;

[0004] 2. Secondly, different woven bags have different sizes. During the sewing process, the sewing positions at the ends are different, and the distance between the conveying structure and the sewing structure needs to be adjusted. During the adjustment process, the whole conveying structure needs to be moved, and the operation is relatively troublesome and inconvenient to use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sewing device for plastic woven bags. By setting a table board, a first belt conveyor, a moving seat, an installation baffle and a second belt conveyor, the problems that the sewing end of the woven bag is prone to deviation from the sewing position during the conveying of the woven bag, and it is not convenient enough to adjust the position of the conveying structure for conveying the woven bag are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a sewing device for plastic woven bags, which comprises a table board, a first belt conveyor, a moving seat, a mounting baffle and a second belt conveyor. One end of the table board is provided with the first belt conveyor and the second belt conveyor, and the first belt conveyor is arranged at the bottom of the second belt conveyor. The length of the first belt conveyor is longer than that of the second belt conveyor. The bottom of the first belt conveyor is symmetrically and fixedly provided with moving seats. One end of the moving seat is rotatably connected with a threaded rod. A mounting baffle is jointly arranged at one ends of the two moving seats. The two threaded rods are both threadedly connected in the mounting baffle. During operation, the sewing machine main body is fixedly penetrated through the table board. The first belt conveyor drives the corresponding woven bag to move between the first belt conveyor and the second belt conveyor, and the end to be sewn is arranged at the sewing position of the sewing machine main body. When the threaded rod is rotated, the threaded connection between the threaded rod and the mounting baffle drives the moving seat to move, so as to change the position of the first belt conveyor.

[0008] Furthermore, a sewing machine main body is vertically and fixedly penetrated through the table board, and a support box is fixedly arranged at the bottom of the table board. During the operation of the table board, the sewing action is provided by the sewing machine main body.

[0009] Furthermore, a fixing plate is fixedly arranged on one side of the first belt conveyor. A limiting plate is fixedly arranged on the side of the fixing plate close to the first belt conveyor. The limiting plate is arranged outside one end of the second belt conveyor. During the operation of the first belt conveyor, the fixing plate is connected with the limiting plate, and the initial position of the woven bag thereon is limited by the limiting plate.

[0010] Furthermore, support rollers are embedded in the bottom of the moving seat in a rectangular array, and the support rollers extend out of the bottom of the moving seat. During the operation of the moving seat, the moving seat is supported on the ground by the support rollers to cooperate with the movement of the moving seat.

[0011] Furthermore, the mounting baffle is arranged on the side of the moving seat away from the support box. Threaded holes are symmetrically and penetratedly formed in the mounting baffle. Mounting ears are fixedly arranged at two corners of the lower part of the side of the mounting baffle away from the moving seat. During the operation of the mounting baffle, the threaded rod is threadedly connected with the threaded hole, and the mounting baffle is mounted at a proper position through the mounting ears.

[0012] Furthermore, the two threaded rods are both threadedly connected in the threaded holes. A rotating frame is fixedly arranged at one end of the threaded rod away from the moving seat. Fixed seats are symmetrically and fixedly arranged at the top of the second belt conveyor. During the operation of the threaded rod, the threaded rod is driven to rotate by rotating the rotating frame.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the deviation between the sewing end and the sewing position of the woven bag is likely to occur during the transportation of the woven bag by arranging a table board, a first belt conveyor and a second belt conveyor. First, place the woven bag on the position of the first belt conveyor that does not coincide with the second belt conveyor. The end of the woven bag is transported to the table board through the first belt conveyor and the second belt conveyor, and then moves to the sewing position of the sewing machine main body through the table board. When the sewing machine main body works, one edge of the woven bag is sewn, so that the woven bag moves to the sewing position stably, making the position of the woven bag more accurate during the transportation process of the woven bag and more convenient to use.

[0015] 2. The utility model solves the problem that it is not convenient enough to adjust the position of the conveying structure for transporting the woven bag by arranging a table board, a first belt conveyor, a moving seat and a mounting baffle. When sewing the ends of woven bags of different lengths, drive the threaded rod to rotate, so that the moving seat drives the first belt conveyor to move until the distance between the edge of the position supported by the first belt conveyor and the edge of the table board close to the first belt conveyor is adjusted to a suitable distance, and then the transportation work of the woven bag can be carried out, making it more convenient to adjust the position of the conveying structure for transporting the woven bag and more convenient to determine the position where the woven bag is transported to the sewing structure.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific embodiment I

[0026] Please refer to Figures 1-3 , the present invention is a plastic woven bag sewing device, including a bedplate 1, a belt conveyor I 2, a moving seat 3, an installation baffle 4 and a belt conveyor II 5. One end of the bedplate 1 is provided with a belt conveyor I 2 and a belt conveyor II 5. The bedplate 1 fixes the sewing machine main body 101 therein. When the belt conveyor I 2 and the belt conveyor II 5 work, the belts are attached to each other to smoothly convey the woven bag to be sewn. And the belt conveyor I 2 is arranged at the bottom of the belt conveyor II 5, and the length of the belt conveyor I 2 is longer than that of the belt conveyor II 5, so that when working, a position for feeding the woven bag is left at the top of the belt conveyor I 2. The bottom of the belt conveyor I 2 is symmetrically fixed with a moving seat 3. The movement of the moving seat 3 drives the belt conveyor I 2 to move. One end of the moving seat 3 is rotatably connected with a threaded rod 301. An installation baffle 4 is jointly arranged at one end of the two moving seats 3. Both threaded rods 301 are threadedly connected in the installation baffle 4. When the threaded rod 301 rotates, through the threaded connection between the threaded rod 301 and the installation baffle 4, the moving seat 3 is driven to move.

[0027] Specifically, a sewing machine main body 101 is vertically and through-fixedly arranged in the bedplate 1. A support box 102 is fixed at the bottom of the bedplate 1. The bedplate 1 fixes the sewing machine main body 101 through it and supports it on the top of the support box 102. The driving structure of the sewing machine is fixed in the support box 102 through it and is connected with the sewing machine main body 101 through a transmission structure to drive the sewing machine main body 101 to work.

[0028] Furthermore, a fixed plate 201 is fixed on one side of the first belt conveyor 2. A limiting plate 202 is fixed on the side of the fixed plate 201 close to the first belt conveyor 2. The limiting plate 202 is arranged outside one end of the second belt conveyor 5. When the first belt conveyor 2 is working, when its upper belt moves, it drives the woven bags placed on the belt to move one by one between the first belt conveyor 2 and the second belt conveyor 5. The belt conveyor is connected to the limiting plate 202 through the fixed plate 201, and the movement of the first belt conveyor 2 is restricted through the limiting plate 202.

[0029] The operation process of this embodiment is as follows: During work, first place the woven bags on the first belt conveyor 2 at a position not overlapping with the second belt conveyor 5. The ends of the woven bags are conveyed to the table board 1 through the first belt conveyor 2 and the second belt conveyor 5, and then move to the sewing position of the sewing machine main body 101 through the table board 1. When the sewing machine main body 101 is working, one edge of the woven bag is sewn well, and then continue to move through the first belt conveyor 2 and the second belt conveyor 5, so that the woven bags move to subsequent processing positions. Specific Embodiment Two

[0031] Please refer to Figures 1-5 , on the basis of Specific Embodiment One, support rollers 303 are embedded in the bottom of the moving seat 3 in a rectangular array. The support rollers 303 extend out of the bottom of the moving seat 3. When the moving seat 3 is working, it is supported on the ground through the support rollers 303, and when moving the first belt conveyor 2, the moving seat 3 and the support rollers 303 cooperate to move.

[0032] Specifically, the installation baffle 4 is arranged on the side of the moving seat 3 away from the support box 102. Thread holes 401 are symmetrically and penetratingly opened in the installation baffle 4. Installation ears 402 are fixed at the two lower corners on the side of the installation baffle 4 away from the moving seat 3. The installation baffle 4 is threadedly connected to the threaded rod 301 through the thread holes 401, and the installation baffle 4 is supported on the ground through the cooperation of the installation ears 402.

[0033] Furthermore, both threaded rods 301 are threadedly connected in the thread holes 401. A rotating frame 302 is fixed at one end of the threaded rod 301 away from the moving seat 3. Fixed seats 501 are symmetrically fixed on the top of the second belt conveyor 5. By rotating the rotating frame 302, the threaded rod 301 is driven to rotate. Since the threaded rod 301 is threadedly connected in the thread holes 401, when the threaded rod 301 rotates, the moving seat 3 is driven to move. When the moving seat 3 moves, the first belt conveyor 2 is driven to move, so that the positions where the ends of different woven bags need to be sewn are aligned with the sewing position of the sewing machine main body 101. The second belt conveyor 5 is supported on an external support structure through the fixed seats 501.

[0034] The operation process of this embodiment is as follows: during operation, when stitching the ends of woven bags with different lengths, the threaded rod 301 is driven to rotate, causing the moving seat 3 to drive the first belt conveyor 2 to move until the edge of the position supported by the first belt conveyor 2 and the edge of the table board 1 near the first belt conveyor 2 are adjusted to an appropriate distance, and then the conveying work of the woven bag can be carried out.
