Description

Technical Field

[0001] The utility model relates to the technical field of tufting machines, in particular to a tufting machine with a pleat smoothing mechanism. Background Art

[0002] Tufting machines are the primary production equipment for tufted carpets. Tufting needles move back and forth, inserting rows of tuft yarn onto the base fabric at high speed, creating neat and dense loops or cut lines. The principle of tufting is similar to that of a sewing machine. Modern tufting machines are equivalent to extremely large sewing machines, differing only in that a single horizontal row of needles houses tens of thousands. Currently, in actual operation, the base fabric of tufted carpets is prone to wrinkling during transport. These wrinkles not only lead to irregularities in the mechanical tufting process, affecting the quality of the carpet, but also excessive wrinkles can easily deform the needles, reducing the machine's service life.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0022] Example: A tufting machine with a pleat smoothing mechanism, such as Figure 1-3 As shown, it includes a tufting machine body 1, a leveling frame 2 is provided on the feeding side of the tufting machine body 1, a pair of vertically parallel support plates 3 are fixedly provided on the leveling frame 2, and a pair of flat plates 4 and inclined plates 5 that respectively support and lift the carpet are fixedly provided between the two support plates 3. One end of the flat plate 4 is connected to the upper end of the inclined plate 5, and the other end of the flat plate 4 and the lower end of the inclined plate 5 are respectively close to and away from the tufting machine body 1, square sliders 6 are respectively provided on the two support plates 3 for vertical sliding, an upper pressing roller 7 is rotatably provided between the two square sliders 6, and the upper pressing roller 7 is parallel to the flat plate 4, and a flip arm 8 is respectively hinged on the two support plates 3, a lower pressing roller 9 is rotatably provided between the two flip arms 8, and the lower pressing roller 9 is parallel to the inclined plate 5.

[0023] like Figure 3 As shown, the support plate 3 is provided with rectangular elongated holes 31 above the flat plate 4 for the square slider 6 to slide. The two vertical side walls of the rectangular elongated holes 31 are provided with limiting grooves 32. Limiting protrusions are fixedly provided on both sides of the square slider 6 and extend into the limiting grooves 32. By using the rectangular elongated holes 31, limiting grooves 32, and limiting protrusions, the square slider 6 can ensure stable sliding of the support plate 3.

[0024] like Figure 1-3 As shown, a screw rod 10 is vertically rotatably mounted on the top of the square slider 6. The screw rod 10 slides through the top of the support plate 3. A nut 12 is fixedly mounted on the top of the support plate 3 and is threadedly connected to the screw rod 10. The upper end of the screw rod 10 is fixedly connected to a flat handle 13. By using the screw rod 10, nut 12, and flat handle 13, it is convenient for the operator to adjust the height of the upper pressure roller 7 and the gap between the upper pressure roller 7 and the flat plate 4, thereby fully adapting to base fabrics of different thicknesses.

[0025] like Figure 3As shown, a circular limiting plate 101 is fixedly provided at the lower end of the screw 10, and the outer diameter of the limiting plate 101 is larger than that of the screw 10. A limiting cylinder 61 is fixedly provided on the square slider 6, which is movably mounted on the limiting plate 101. A limiting ring 62 is fixedly provided on the top of the limiting cylinder 61, which is movably mounted on the lower end of the screw 10. By adopting the above-mentioned limiting plate 101, limiting cylinder 61 and limiting ring 62, a rotational connection between the lower end of the screw 10 and the top of the square slider 6 can be achieved, and then, in conjunction with the nut 12 and the handle, the height of the square slider 6 and the upper pressure roller 7 can be effectively adjusted.

[0026] like Figure 1 As shown, a three-phase asynchronous motor 14 is fixedly installed on the side of the square slider 6 facing away from the other square slider 6. The two ends of the upper pressure roller 7 rotate through the two square sliders 6 respectively, and one end is fixedly connected to the output end of the three-phase asynchronous motor 14. By adopting the above-mentioned three-phase asynchronous motor, the upper pressure roller 7 can be driven to rotate, and then cooperate with the flat plate 4 to actively transport the base fabric into the tufting machine.

[0027] like Figure 2 、 Figure 3 As shown, the two flip arms 8 are located on opposite sides of the two support plates 3, and the lower pressure roller 9 is located between the two support plates 3. Each support plate 3 has an arc-shaped elongated hole 33, which is located above the inclined plate 5. The center of the arc-shaped elongated hole 33 coincides with the rotation center of the flip arm 8. The two ends of the lower pressure roller 9 slide through the arc-shaped elongated holes 33 on the two support plates 3 and are rotatably connected to the two flip arms 8. By using these arc-shaped elongated holes 33, not only can the flip arm 8 and the upper pressure roller 7 be rotatably connected, but the flipping stability of the flip arm 8 can also be guaranteed.

[0028] like Figure 2 、 Figure 4 As shown, the lower pressing roller 9 is hollow inside, and has a water inlet 91 and a water outlet 92 at each end. The two ends of the lower pressing roller 9 rotate through the middle of the two turning arms 8 and are connected to a water inlet pipe 16 and a water outlet pipe 17 via a rotary joint 15. By using the water inlet pipe 16 and the water outlet pipe 17, hot water can be injected into the interior of the lower pressing roller 9 to increase the temperature of the lower pressing roller 9. This, in conjunction with the inclined plate 5, irons the base fabric, thereby further maintaining the flatness of the base fabric surface.

[0029] like Figure 1 、 Figure 2As shown, a right-angled trapezoidal slide 18 is horizontally slidably provided on the opposite sides of the two support plates 3, and a pair of cylinders 19 is fixedly installed on the leveling frame 2, and the front ends of the piston rods of the two cylinders 19 are fixedly connected to the two slides 18, respectively. One end of the flip arm 8 is hinged to the support plate 3 and is located above the arc-shaped long hole 33. The other end of the flip arm 8 moves below the arc-shaped long hole 33 and is located above the slope of the slide 18. When the slide 18 slides, its slope contacts the end of the flip arm 8 and pushes the flip arm 8 to flip upward. By adopting the above-mentioned slide plate 18 and cylinder 19, when it is necessary to pull the base cloth through the gap between the lower pressure roller 9 and the inclined plate 5, first start the cylinder 19 to drive the slide plate 18 to slide, so that its slope contacts the end of the flip arm 8 and pushes the flip arm 8 to flip upward, and then the flip arm 8 rotates the connected lower pressure roller 9, which will rise and move away from the inclined plate 5 during the upward flipping of the flip arm 8, so as to expand the gap between the lower pressure roller 9 and the inclined plate 5 to a certain extent, and finally, after the lower end of the flip arm 8 slides to and stays at the top of the slope of the slide plate 18, the lower pressure roller 9 is completely fixed at the position farthest from the inclined plate 5, so as to ensure that the staff can safely and conveniently pull the base cloth through the gap between the lower pressure roller 9 and the inclined plate 5.

[0030] Among them, a horizontal dovetail groove 34 is opened on the side of the support plates 3 facing away from each other, and a dovetail slider 181 is fixedly set on one side of the skateboard 18, which slides inside the dovetail groove 34, which can effectively ensure the sliding stability of the skateboard 18; the flip arm 8 is movable at one end below the arc-shaped long hole 33 and is rotatably provided with a roller 81. The roller 81 and the slope of the skateboard 18 are in rolling contact, which can reduce the friction between the lower end of the flip arm 8 and the slope of the skateboard 18, so that the flip arm 8 can flip upward smoothly.

[0031] The working principle of this embodiment is as follows:

[0032] Before the base cloth enters the tufting machine for tufting processing, the base cloth will pass through the gap between the inclined plate 5 and the lower pressing roller 9, and the gap between the flat plate 4 and the upper pressing roller 7 in sequence. Among them, the inclined plate 5 can allow the base cloth to be spread out obliquely downward. At the same time, the lower pressing roller 9 connected by rotation between the two flip arms 8 will press the base cloth above the inclined plate 5 under its own gravity, and pull the base cloth to slide obliquely downward along the inclined plate 5 to a certain extent. Since the flat plate 4 and the upper pressing roller 7 hold the front base cloth at the upper end of the inclined plate 5, and the upper pressing roller 7 transports the base cloth into the tufting machine by rotation, the base cloth on the inclined plate 5 will remain flat under the action of the gravity of the lower pressing roller 9, thereby effectively preventing the occurrence of wrinkles in the base cloth.
