Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric printing machines, in particular to a leveling device for non-woven fabric printing machines. Background Art

[0002] The flattening device for nonwoven printing machines is specifically designed to ensure a smooth, even laydown of nonwovens during the printing process. Its operating principle is to mechanically apply tension and traction to the nonwoven, maintaining a flat surface on the printing machine's work platform, ensuring accurate and uniform printing. For example, as the nonwoven fabric is conveyed from the unwinder to the printing area, rollers or clamping components within the flattening device come into contact with the nonwoven. Through a controlled speed differential and pressure, the flattening device unrolls and flattens the fabric, eliminating any wrinkles or slack.

[0003] The existing flattening method achieves the flattening effect by wrapping it around a flattening rod, but the existing method has certain defects. It is not convenient to adjust the tightness of the non-woven fabric during the stretching process, which can easily cause the non-woven fabric to be damaged due to being too tight, and wrinkles to appear due to being too loose.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-4A leveling device for a non-woven fabric printing machine includes a base 1. The four corners of the bottom end of the base 1 are fixedly connected to support legs 31. Two rollers 2 are provided on the base 1. Both ends of the roller 2 are rotatably connected to a fixed plate 3. The fixed plate 3 is fixedly connected to the base 1. A first motor 4 is installed on the fixed plate 3. The output end of the first motor 4 passes through the fixed plate 3 and is connected to a first gear 5. A second gear 6 is sleeved on the roller 2. The second gear 6 is meshed with the first gear 5, so that the first motor 4 drives the roller 2 to rotate through the cooperation of the first gear 5 and the second gear 6. Two slides 19 are fixedly connected to the top plate 18. A slide 20 is slidably sleeved on the slide 19. The slide 20 is fixedly connected to the base 1. An electric push rod 21 is installed on the slide 20. The electric push rod 21 The output end is connected with the slide plate 19, so that the electric push rod 21 drives the top plate 18 to rise and fall through the slide plate 19. The bottom end of the top plate 18 has two pads 22, and the bottom end of the pad 22 is fixedly connected to two mounting brackets 23. A through groove is provided on the mounting bracket 23, and a connecting block 24 is slidably connected in the through groove. A limiting block 30 is fixedly connected to the connecting block 24, and the opposite end of the two connecting blocks 24 is rotatably connected to the flower roller 7. The top of the connecting block 24 is fixedly connected with a connecting rod 25, and the top of the connecting rod 25 passes through the mounting bracket 23 and is connected to the limiting plate 26. A spring 27 is sleeved on the connecting rod 25. By setting the spring 27, the flower roller 7 and the pressure roller can be buffered by the spring 27 when processing the non-woven fabric to avoid the problem of excessive pressure causing excessive load on the first motor 4.

[0026] It should also be noted that a leveling rod 10 is rotatably connected between the two mounting blocks 9, and two retaining rings 29 are fixedly sleeved on the leveling rod 10, and the non-woven fabric is limited by the retaining ring 29. The top of the mounting block 9 is fixedly connected to two guide columns 11, and the top of the guide column 11 passes through the top plate 18. A mounting groove is provided on the guide column 11, and a fixed cylinder 12 is slidably connected in the mounting groove. The fixed cylinder 12 is fixedly connected to the lifting plate 8, and a tension spring 13 is provided in the fixed cylinder 12.

[0027] In summary, the working principle and working process of the leveling device for the non-woven fabric printing machine are as follows: when in use, the non-woven fabric is first passed between the flower roller 7 and the rotating roller 2, and then around the leveling rod 10, and the electric push rod 21 is turned on, so that the electric push rod 21 drives the flower roller 7 to move through the slide 19, so that the flower roller 7 and the rotating roller 2 cooperate to clamp the non-woven fabric, and then the first motor 4 is turned on, so that the first motor 4 drives the rotating roller 2 to rotate through the first gear 5 and the second gear 6 to process and transmit the non-woven fabric, and at the same time, the screw 17 is driven to rotate by the second motor 16, so that the screw 17 drives the leveling rod 10 to rise and fall through the lifting plate 8 to adjust the leveling force of the non-woven fabric.

[0028] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
