Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, and in particular to a folding and shaping device for producing clothing bags using a bag making machine. Background Technology

[0002] A bag-making machine is an automated device used to produce packaging bags made of various plastics, non-woven fabrics, or composite materials. When making clothing bags, a folding and shaping device is usually used to pre-fold and fix the edges of the material during the bag-making process to ensure that the edges are neat and firm when heat-sealed or sewn later, avoiding the material from becoming loose or deformed, while improving the strength, sealing, and aesthetics of the bag.

[0003] For example, Chinese Patent Publication No. CN223085567U discloses a folding mechanism for a bag-making machine, relating to the field of bag-making machine devices. This folding mechanism for a bag-making machine includes a processing platform disposed inside the bag-making machine. A folding component is disposed on the top of the processing platform, and a lifting plate is disposed inside the folding component. A vertical plate is rotatably connected to the side wall of the lifting plate, and the vertical plate is used to lift the lifting plate. Rollers are disposed on the top of the processing platform, distributed on both sides of the folding component, and circular blocks are disposed on both sides of the rollers.

[0004] The aforementioned device uses a folding piece and an adjustable lifting plate to fold the material strips of different thicknesses. However, in actual use, due to the different sizes of clothing bags, the existing device is not convenient for use with fabrics of different widths. At the same time, folding the fabric only through the folding piece makes the fabric prone to loosening during subsequent conveying, resulting in poor production quality of clothing bags. Utility Model Content

[0017] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.

[0018] Example Reference Figures 1 to 5 A folding and shaping device for producing clothing bags using a bag-making machine includes an operating table 1. Equipment housings 2 are fixedly connected to both sides of the operating table 1. A guide component 5 is embedded between the two sets of equipment housings 2. A sewing part 3 and a folding component 4 are spaced apart on opposite sides of the two sets of equipment housings 2, and the two sets of sewing parts 3 and folding components 4 are symmetrically arranged. The two sets of folding components 4 are embedded in the upper end of the operating table 1. The sewing part 3 is used to sew the fabric, the folding component 4 is used to fold and shape the side edges of the fabric, and the guide component 5 is used to guide the fabric.

[0019] The folding assembly 4 includes a limiting component 41 embedded on one side of the equipment housing 2 and a single folding pull tube 42 disposed on one side of the limiting component 41. The limiting component 41 is provided with a pressing component 44 running through it vertically. A heating plate 43 and a heat insulation plate 45 are embedded and fixedly connected to the upper end of the operating table 1. There are two sets of heating plates 43. The heat insulation plate 45 is disposed between the two sets of heating plates 43. It should be noted that the folding of the fabric edge by the single folding pull tube 42 is a known prior art. Those skilled in the art can conceive of the specific structure. The limiting component 41 and the pressing component 44 are used to make the fabric come into contact with the heating plate 43. The heating plate 43 can heat and temporarily shape the fabric. The heat insulation plate 45 is used to block the heat conduction between the two sets of heating plates 43.

[0020] The limiting component 41 includes an electric telescopic rod 411 that is embedded and fixedly connected to one side of the equipment housing 2. One end of the electric telescopic rod 411 is fixedly connected to an L-shaped mounting plate 412. A set of heating plates 43 are arranged below the L-shaped mounting plate 412. The horizontal position of the L-shaped mounting plate 412 can be adjusted by the electric telescopic rod 411.

[0021] Sliding blocks 413 are fixedly connected to both sides of the L-shaped mounting plate 412. The lower ends of the two sets of sliding blocks 413 are slidably connected to the upper end of the operating table 1 through trapezoidal sliders. A threaded sleeve 414 is fixedly connected through the upper end of the L-shaped mounting plate 412. The vertical stability of the L-shaped mounting plate 412 can be improved by limiting the sliding blocks 413.

[0022] The extrusion component 44 includes a bolt 441 that is threadedly connected to the threaded sleeve 414. A limit plate 442 is fixedly connected to the lower end of the bolt 441. A single-flanged pull cylinder 42 is detachably installed on one side of the limit plate 442. A guide rod 443 is fixedly connected to the upper end of the limit plate 442. Multiple sets of guide rods 443 are spaced apart. All sets of guide rods 443 are movably connected to the L-shaped mounting plate 412. The rotation of the limit plate 442 can be restricted by the multiple sets of guide rods 443. The height of the limit plate 442 can be adjusted by rotating the bolt 441. When the limit plate 442 moves, it will drive the single-flanged pull cylinder 42 to move together.

[0023] A limiting rod 444 is movably connected between the limiting plate 442 and the L-shaped mounting plate 412. A spring 445 is fixedly connected between the upper end of the limiting rod 444 and the L-shaped mounting plate 412. Two sets of springs 445 and limiting rods 444 are provided at intervals. An extrusion plate 446 is fixedly connected to the lower end of the two sets of limiting rods 444. A clearance groove is provided below the limiting plate 442 for the extrusion plate 446 to fit into. The two sets of springs 445 are used to pull the limiting rods 444 downward, so that the two sets of limiting rods 444 press the extrusion plate 446 downward to contact the fabric.

[0024] The guide assembly 5 includes a drive unit 51 fixedly installed on one side of a set of equipment housings 2. Two sets of guide rollers 52 are spaced apart on one side of the drive unit 51, and the distance between the two sets of guide rollers 52 is adjustable. One end of each set of guide rollers 52 is rotatably connected to one side of another set of equipment housings 2. It should be noted that the drive unit 51 enables the two sets of guide rollers 52 to rotate in opposite directions and adjusts the distance between the two sets of guide rollers 52, which are known prior art. Those skilled in the art are able to conceive of the specific structure.

[0025] In this invention, before folding the fabric, the distance between the two sets of L-shaped mounting plates 412 is adjusted by two sets of electric telescopic rods 411. The limiting plate 442 and the single-folding hem pull cylinder 42 move with the L-shaped mounting plate 412. This distance adjustment allows the device to adapt to fabrics of different widths. Then, the height of the limiting plate 442 is adjusted by rotating the bolt 441, allowing the device to adapt to fabrics of different thicknesses. The fabric is then mounted on both sides of the two sets of single-folding hem pull cylinders 42, allowing the fabric to be sewn between the pressing plate 446 and a heating plate 43. The fabric passes between the lower part 3 and the two sets of guide rollers 52, so that the extrusion plate 446, the limiting plate 442, and a set of heating plates 43 are all in contact with the fabric. The extrusion plate 446 squeezes the fabric under the elastic force of the spring 445. The two sets of guide rollers 52 rotate in opposite directions through the drive unit 51, and the fabric is wound up by the external winding structure. When the fabric passes through the single folding edge pull tube 42, the edge of the fabric is folded. Then, under the guidance of the limiting plate 442, the folded edge of the fabric will initially contact the heating plate 43, which can soften the fabric. Then, under the squeezing action of the extrusion plate 446, the fabric is further softened. The fabric hem is squeezed into close contact with a set of heating plates 43. This pressure heats and temporarily sets the fabric, reducing the possibility of loose hems during transport. The hem is then sewn as it passes under the sewing section 3. The two sets of heating plates 43 accommodate fabrics of different widths, and only one set needs to be activated at a time, reducing energy consumption for heating and setting. This invention enables automatic hem setting of fabric during garment bag production using a bag-making machine. The single hem pull tube 42 is horizontally... The device's vertical position adjustment allows it to adapt to fabrics of different thicknesses and widths. Simultaneously, the setting of the limiting component 41, heating plate 43, and extrusion component 44 enables heating and shaping. The device employs a secondary heating and shaping method, which preheats the fabric, preventing fiber embrittlement caused by sudden high temperatures. Staged pressure application fully softens the fibers, and the extrusion plate 446 ensures proper edge adhesion, reducing springback and improving the heating and shaping effect. This reduces the possibility of loose edges during fabric transport, thus improving the production quality of the garment bags.
