[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1-4 This utility model provides a printing device for woven bag production, including a fixed frame 5 and a printing machine 1 mounted on top of the fixed frame 5. A leveling component for scraping the woven bag is located on the top of the fixed frame 5 and on one side of the printing machine 1. A cylinder 4 is rotatably connected to the inner side of the fixed frame 5 via bearings. Multiple evenly distributed telescopic rods 19 are bolted to the outer wall of the cylinder 4. A movable plate 18 is bolted to the piston ends of two horizontally positioned telescopic rods 19. Multiple evenly distributed sliding grooves 21 are formed on the outer wall of the cylinder 4, penetrating the cylinder 4. A slider 17 is slidably connected to the inner wall and outer wall of the cylinder 4 within the multiple sliding grooves 21. Multiple evenly distributed connecting rods 16 are rotatably connected to the outer side of the slider 17 via bearing seats. The other side of the connecting rod 16... One end is rotatably connected to the moving plate 18, and the connecting rod 16 corresponds one-to-one with the moving plate 18. The inner walls of both sides of the cylinder 4 are provided with a drive assembly that drives the slider 17 to move left and right. The inner side of the fixed frame 5 is rotatably connected to the guide roller 3 through the bearing. When the woven bag being transported becomes loose or skewed, the drive assembly is rotated, and the drive assembly drives the slider 17 to move to the right along the slide groove 21. At the same time, the slider 17 pushes multiple moving plates 18 to move outward along the direction of the telescopic rod 19 through multiple connecting rods 16, thereby increasing the distance between the multiple moving plates 18 around which the woven bag is wrapped, and thus making the transported woven bag tighter. This solves the problem that the woven bag is prone to loosening and skewing during transport, resulting in printing position deviation or pattern overlap, and greatly improves the printing quality.

[0022] In this embodiment, the driving component includes a lead screw 20 rotatably connected to the inner walls of both sides of the cylinder 4 via bearings, and the lead screw 20 is threadedly connected to the slider 17, with one end of the lead screw 20 passing through the cylinder 4.

[0023] In this embodiment, the leveling component includes a support frame 2 fixed to the top of the fixing frame 5 by bolts. Two guide rods symmetrically arranged are fixed to the top and edge of the support frame 2 by bolts. A connecting plate 8 is slidably connected to the outer side of the two guide rods 6. A scraper 9 that contacts the woven bag is fixed to the bottom of the connecting plate 8 by bolts. An elastic component that applies tension to the connecting plate 8 is provided on the outer side of the guide rods 6. The elastic component includes a tension spring 7 sleeved on the outer side of the guide rods 6. One end of the tension spring 7 is fixed to the support frame 2, and the other end is fixed to the connecting plate 8. The tension of the elastic component pulls the connecting plate 8 downward, and the connecting plate 8 drives the scraper 9 to move downward and contact the woven bag, thereby applying pressure to the woven bag and preventing wrinkles from forming in the woven bag during transportation.

[0024] In this embodiment, two symmetrically arranged slide rails 15 are fixed to the top of the fixed frame 5 by bolts. Two symmetrically arranged guide frames 13 are slidably connected to the top of the two slide rails 15 by a slide table. Two symmetrically arranged fixed plates 14 are fixed to the top of the fixed frame 5 by bolts. A bidirectional threaded rod 12, which is threaded to the two guide frames 13, is rotatably connected between the two fixed plates 14 and between the two slide rails 15 by a bearing. By rotating the bidirectional threaded rod 12, the bidirectional threaded rod 12 drives the two guide frames 13 to move inward towards each other, so that the guide frames 13 come into contact with the woven bag, thereby avoiding the phenomenon of transmission deviation during the transmission of the woven bag.

[0025] In this embodiment, a plurality of evenly distributed grooves 11 are provided on one side of the guide frame 13. Rollers 10 are rotatably connected inside the grooves 11. The woven bag contacts the rollers 10, thereby greatly reducing the friction between the woven bag and the guide frame 13.

[0026] In this embodiment, the top end of the guide rod 6 is fixed with a baffle to prevent the connecting plate 8 from detaching from the guide rod 6 by bolts.

[0027] It should be noted that printing machine 1 is existing technology, including print head, print roller and printing ink, etc. Those skilled in the art can set it according to actual needs, which will not be described in detail here.

[0028] In this application, an annular groove is axially provided on the inner wall of the threaded hole that mates with the bidirectional threaded rod 12 and the lead screw 20. A nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit of 15°-20° with the surface of the bidirectional threaded rod 12 and the lead screw 20. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening and skew displacement caused by thread springback.

[0029] The use of this utility model involves the following steps: S1: The woven bag, which has been woven in the weaving machine, first passes through the fixed frame 5, then around the bottom of the guide roller 3, then around the multiple moving plates 18, then through the support frame 2 and the scraper 9, and enters the printing machine 1, and finally connects to the cutting machine. S2: When the woven bag being transported becomes loose or skewed, rotate the lead screw 20. The lead screw 20 drives the slider 17 to move to the right along the slide groove 21. At the same time, the slider 17 pushes multiple moving plates 18 to move outward along the direction of the telescopic rod 19 through multiple connecting rods 16. This increases the distance between the multiple moving plates 18 around which the woven bag is wrapped, thereby making the woven bag being transported tighter. S3: Then rotate the double-threaded rod 12. The double-threaded rod 12 drives the two guide frames 13 to move inward towards each other, so that the guide frames 13 contact the woven bag, thus avoiding the phenomenon of transmission deviation during the transmission of the woven bag. S4: At the same time, the tension of the tension spring 7 pulls the connecting plate 8 downward, and the connecting plate 8 drives the scraper 9 to move downward, contacting the woven bag and applying pressure to the woven bag, thereby preventing the woven bag from wrinkling during the transmission process.

[0030] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
