Description

Technical Field

[0001] The utility model relates to the technical field of work clothes processing, in particular to a limiting device for a flat plate cutting machine. Background Art

[0002] Flatbed cutting machines can be used for both cutting and drawing, so they are often called flatbed cutting and plotting machines. Flatbed cutting machines can process various materials with precise performance and can meet various types of industrial needs.

[0003] During the production process of work clothes, samples made of sample paper rolls are needed. When the sample paper roll is unrolled on the flatbed cutting machine, when its width changes, it cannot be effectively limited in the conveying direction, resulting in the sample paper not being unrolled along the width direction of the workbench. In this way, the subsequent flatbed cutting machine cannot make the most of the sample paper roll to draw and cut on its surface. Utility Model Content

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] A limiting device for a flat-plate cutting machine in this embodiment includes a workbench 1, an unwinding mechanism 2 and a limiting mechanism.

[0032] like Figure 1 As shown, one end of the workbench 1 is a feed end 3, and the other end is a discharge end 4; the upper surface of the workbench 1 is kept horizontal.

[0033] The unwinding mechanism 2 is arranged at the lower part of the feeding end 3 of the workbench 1 and is used for unwinding the placed sample paper roll.

[0034] The limiting mechanism includes a vertical limiting mechanism and a horizontal limiting mechanism.

[0035] The vertical limiting mechanism includes a support frame 5, a cylinder 6 and a limiting transverse plate 7; the support frame 5 is arranged on the feeding end of the workbench 1; the cylinder 6 is arranged at the top middle position of the support frame 5, and the piston rod of the cylinder 6 is arranged vertically downward; the limiting transverse plate 7 is horizontally fixed to the end of the piston rod of the cylinder 6, and is arranged along the width direction of the workbench 1, and a gap is left between the limiting transverse plate 7 and the upper surface of the workbench 1 for the sample paper being unwound to pass through.

[0036] In this embodiment, guide rods 8 are vertically symmetrically provided on both sides of the piston rod of the cylinder 6 on the limiting cross plate 7, and the two guide rods 8 slide through the top of the support frame 5; such a configuration ensures that the limiting cross plate 7 moves in the vertical direction.

[0037] Furthermore, in this embodiment, if Figure 2 As shown, a guide roller 9 is also horizontally rotatably provided at the feed end 3 of the workbench 1, and the guide roller 9 is located above the unwinding mechanism 2; the sample paper on the unwinding mechanism 2 is accurately fed to the feed end 3 of the workbench 1 under the guidance of the guide roller.

[0038] like Figure 3 As shown, the horizontal limit mechanism includes a horizontal limit bar 11, a slider 13 and a bolt 12; a slide groove 10 is provided at a position close to the feed end 3 and the discharge end 4 on one side of the upper surface of the workbench 1, and the slide groove 10 is arranged along the width direction of the workbench 1; the number of the sliders 13 is two, and the two sliders 13 are respectively slidably arranged on the two slide grooves 10, and the two sliders 13 are vertically provided with threaded through holes, and the threaded through holes are adapted to the bolts 12; the horizontal limit bar 11 is provided with through holes 15 near its two ends; as shown Figure 4As shown, the bolt 12 passes through the through hole 15 and is threadedly sleeved on the threaded through hole of the slider 13; the horizontal limit strip 11 is always arranged along the length direction of the workbench 1; in this way, according to the width of the sample paper roll, the position of the horizontal limit strip 11 on the workbench 1 is adjusted, and the bolt 12 is turned so that the bottom of the bolt 12 contacts the bottom of the slide groove 10, and the bolt 12 is continued to be turned, and finally the slider 13 is tightly fitted with the top inner wall of the slide groove 10, thereby effectively fixing the horizontal limit strip 11.

[0039] In this embodiment, a pad 14 is welded to the bottom of the bolt 12. With this arrangement, since the bottom area of ​​the bolt 12 is relatively small, after the bolt is tightened for a long time, the bottom of the slide groove is easily pressed into multiple grooves. By providing the pad 14, the pressure of the bolt on the bottom of the slide groove is effectively reduced.

[0040] In this embodiment, a spring (not shown in the figure) is sleeved on the bolt 12, and the spring is located between the horizontal limit bar and the slider; with this arrangement, after loosening the bolt 12, the spring can lift the horizontal limit bar, and the staff can move the position of the horizontal limit bar to avoid friction between the horizontal limit bar and the workbench.

[0041] When the above-mentioned limiting device is in use, the sample paper roll is first placed on the unwinding mechanism 2, and according to the thickness of the sample paper roll, the cylinder 6 on the vertical limiting mechanism is started, so that the gap between the limiting cross plate 7 and the workbench 1 is adapted to the thickness of the sample paper roll to be unrolled; the position of the horizontal limiting strip 11 on the slide groove 10 is moved to adapt it to the width of the sample paper roll to be unrolled, and it is effectively limited in the horizontal direction; then the sample paper roll can be unrolled.

[0042] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
