Description

Technical Field

[0001] This utility model relates to the field of woven bag sewing technology, and in particular to a fully automatic hand-held woven bag sewing machine. Background Technology

[0002] A bag sewing machine is a device designed for sewing the openings of plastic woven bags, paper bags, paper-plastic composite bags, aluminum-coated paper bags, etc. It mainly completes the splicing and sewing of bags or woven materials. Its advantages include good sealing performance, high strength, easy disassembly, and reusability of the bags after sewing.

[0003] Currently, after woven bags are completed, the bag opening needs to be sewn shut using a sewing machine. In existing technology, the woven bag sewing machine places the bag on top of a conveyor belt, and the bag opening is moved to the sewing machine's sewing point by the conveyor belt. However, in this process, because there is no clamping mechanism at the bag opening, this lack of clamping can easily cause the woven bag to become skewed during the sewing process, thus affecting the sewing quality. To address this, we propose a fully automatic hand-held woven bag sewing machine. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a fully automatic hand-held woven bag sewing machine that uses elastic connectors to enable two sets of conveyor belts to clamp and transport the woven bags.

[0005] To solve the above-mentioned technical problems, the present invention addresses the issue of low precision in sewing the opening of woven bags through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fully automatic woven bag sewing machine includes a base. Two sets of symmetrically arranged fixed plates are fixedly connected to the end of the base. Multiple sets of sliding columns are slidably connected to the fixed plates. Elastic connectors are installed on the sliding columns. Fixed frames are fixedly connected to the ends of the multiple sets of sliding columns on the same side. Support blocks are fixedly connected to the fixed frames. Rotating shafts that are rotatably connected to the fixed frames are installed at both ends of the support blocks. Rotating rollers are fixedly connected to the outer side of the rotating shafts. Conveyor belts are sleeved on the outer side of the rotating rollers. A rotating component for driving the two sets of rotating shafts to rotate in opposite directions is installed between the two sets of rotating shafts.

[0007] Preferably, the rotating component includes a first bevel gear fixedly connected to two sets of rotating shafts respectively, a second bevel gear meshing with the outer surface of the first bevel gear, a transmission shaft body connected to the axis of the two sets of second bevel gears, a connecting frame rotatably connected to the rotating shaft on the outer surface of the transmission shaft body, and a driving component installed at the end of the transmission shaft body.

[0008] Preferably, the transmission shaft is fixedly connected to the base, and a rotating block is rotatably connected to the fixed base. Both ends of the rotating block are fixedly connected to a first prismatic column. The outer surface of the first prismatic column is slidably connected to a sliding shaft. The two sets of sliding shafts are respectively fixedly connected to two sets of second bevel gears, slidably connected to two sets of fixed plates, and rotatably connected to two sets of connecting frames.

[0009] Preferably, the driving component includes a support frame fixedly connected to the base, a motor fixedly connected to the support frame, a drive shaft fixedly connected to the output end of the motor, and a second prismatic column fixedly connected to the end of the drive shaft and slidably connected to the sliding shaft.

[0010] Preferably, the elastic connector includes a fixing plate fixedly connected to the fixing plate, the fixing plate being slidably connected to the sliding column, and a spring sleeved on the outer side of the sliding column being fixedly connected to the fixing plate. The end of the spring is fixedly connected to a connecting plate fixedly connected to the sliding column, which facilitates the adaptation to woven belts of different thicknesses. Furthermore, the compression action of the spring ensures that the two sets of conveyor belts fit tightly against the woven bag, facilitating the conveying of the woven bag.

[0011] Preferably, the outer side of the conveyor belt is fixedly connected with anti-slip strips to increase the friction between the conveyor belt and the woven bag, thereby facilitating the conveying of the woven bag to the sewing position.

[0012] Preferably, adjustable support legs are fixedly connected to the bottom corners of the base, which helps to improve the stability of the device.

[0013] Preferably, a support plate is fixedly connected between the two sets of fixed plates. The support plate is installed at the top of the connecting frame and sleeved on the outer side of the rotating shaft. This facilitates the support of the woven bag, improves the sewing accuracy, and prevents the woven bag from contacting the parts in the rotating assembly, thereby avoiding damage to the woven bag.

[0014] Preferably, a sewing frame is provided on the outer side of the base, an automatic sewing head is installed on the sewing frame, and a sewing frame is installed on one side of the automatic sewing head to facilitate automatic sewing of the woven bag.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention features two sets of vertically arranged conveyor belts. An elastic connector allows the two conveyor belts to clamp and transport the woven bag. The elastic connector also allows for adjustable spacing between the two conveyor belts, facilitating the transport of woven bags of varying thicknesses. Springs ensure the two conveyor belts fit tightly against the woven bag, providing a secure grip and moving the bag to the automatic sewing position. This solves the problem in existing technologies where the lack of a clamping mechanism affects the sewing accuracy of woven bags. Attached Figure Description

A sliding shaft 19 is slidably connected to the outer side of the first prismatic column 18. The two sets of sliding shafts 19 are fixedly connected to the two sets of second bevel gears 12 respectively, and are slidably connected to the two sets of fixed plates 2 respectively, and are rotatably connected to the two sets of connecting frames 14 respectively.

[0023] Please see Figure 3 and Figure 4 The driving component 15 shown in the figure includes a support frame 20 fixedly connected to the base 1. A motor 21 is fixedly connected to the support frame 20. A drive shaft 22 is fixedly connected to the output end of the motor 21.

[0029] During implementation, when sewing the woven bag, the woven bag is placed between two sets of conveyor belts 9. At this time, the woven bag can be clamped by the action of spring 25. Then, the motor 21 is started, which drives the drive shaft 22 to rotate. The rotation of the drive shaft 22 drives the second prismatic column 23 fixedly connected to it to rotate, which in turn drives the sliding shaft 19 slidably connected to it to rotate, which in turn drives the first prismatic column 18 to rotate. The rotating block 17 and the other set of first prismatic columns 18 drive the other set of sliding shafts 19 slidably connected to them to rotate. During the start of the motor 21, both sets of sliding shafts 19 will rotate. The rotation of the two sets of sliding shafts 19 drives the second bevel gear 12 to rotate, which in turn drives the first bevel gear 11 to rotate, which in turn drives the rotating shaft 7 to rotate, which in turn drives the rotating roller 8 to rotate, which in turn drives the conveyor belt 9 to rotate. The woven bag is conveyed by the rotation of the conveyor belt 9. It is worth noting that the distance between the two sets of conveyor belts 9 can be varied by the action of the sliding column 3 and the spring 25, which makes it easier to transport woven bags of different thicknesses, thus improving the practicality of the device. In addition, the action of the spring 25 can make the two sets of conveyor belts 9 and the support block 6 tightly clamp the woven bags, thereby improving the sewing accuracy of the woven bags.
