Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment and relates to automatic production equipment for Chinese knots. Background Art

[0002] The Chinese knot is a kind of hand-woven handicraft. Up to now, there are many styles of Chinese knots. Some Chinese knots are woven from beginning to end with a single silk thread; another kind of Chinese knot is made by winding a rope around a specific mold, and then gluing panels printed with the word "Fu" on both sides of the wound rope. Part of the wound rope is fixed between two panels, and another part extends out of the panels and is bent to form the shape of a Chinese knot.

[0003] In comparison, the first method can better reflect the traditional weaving craftsmanship, while the second method retains the traditional appearance of the Chinese knot, while being simpler and faster to process and produce, and can also make the Chinese knot more diverse through the patterns on the panel. As for the second weaving method, the Chinese knots currently on the market are all hand-woven, which has the problem of low work efficiency. Utility Model Content

The rope-pulling device comprises three groups, and a square forming station is arranged on the frame 1. The three groups of rope-pulling devices and wire-introducing guide assemblies are respectively arranged at the four top corners of the forming station. The three groups of rope-pulling devices respectively move back and forth along the diagonal direction of the forming station to pull the rope 2 wound on the wire-introducing guide assembly. The positioning device comprises a plurality of liftable shaping assemblies arranged on the periphery of the forming station. The rope-pushing device comprises four groups, which are arranged on the four sides of the forming station to push the rope 2 pulled open by the rope-pulling device, so that the rope 2 is bent and wound around each shaping assembly.

[0027] like Figure 2 As shown, the wire-inlet guide assembly includes a plurality of guide posts 4, which are divided into two groups and arranged symmetrically at intervals. The rope 2 is wound around the guide posts 4 to form a U-shaped structure with the opening facing outward. The rope-pulling device includes a mounting plate 5, a driving cylinder 1 6, a wire-pulling post 7, and a driving cylinder 2 8. The driving cylinder 1 6 is fixed on the frame 1 and is used to drive the mounting plate 5 to move back and forth along the diagonal direction of the forming station; the driving cylinder 2 8 is fixed on the mounting plate 5 and is used to drive the wire-pulling post 7 to move up and down. A total of two wire-pulling posts 7 are arranged on the rope-pulling device opposite to the wire-inlet guide assembly. The two wire-pulling posts 7 are arranged at intervals along the direction of their movement, and the gap between the two wire-pulling posts 7 can accommodate the rope 2 to enter and exit.

[0028] like Figure 3 As shown, the shaping assembly includes a positioning ring 10 and a positioning block 9. The frame 1 is also provided with a driving cylinder 3 for driving the positioning ring 10 and the positioning block 9 to rise and fall. There are four groups of positioning blocks 9, which are arranged on the four sides of the forming station.

[0032] The working principle of the utility model is as follows:

[0033] The worker first winds the two strands of rope 2 around the guide column 4 and bends them into a U-shaped structure with the opening facing outward, and drives the cylinder 9 23 to drive the pressure rod 22 to descend and be placed above the rope 2 to prevent the rope 2 from detaching from the guide column 4 during the pulling process;

[0034] The driving cylinder 16 on the rope pulling device opposite to the wire guide assembly drives the mounting plate 5 to move in a direction close to the rope 2 until the wire pulling column 7 is above the rope 2. The driving cylinder 28 drives the wire pulling column 7 to descend. The driving cylinder 16 drives the mounting plate 5 to reset and pull the rope 2 out through the wire pulling column 7. After the first pull, the rope 2 is as shown in FIG. Figure 5 As shown;

[0035] The driving cylinder 1 6 on the two sets of rope pulling devices adjacent to the wire guide assembly drives the mounting plate 5 to move in a direction close to the center of the forming station until the wire pulling column 7 is located above the rope 2. The driving cylinder 2 8 drives the wire pulling column 7 to descend. The driving cylinder 1 6 drives the mounting plate 5 to reset and pull the rope 2 out through the wire pulling column 7. After the second pull, the rope 2 is as shown in FIG. Figure 6 As shown;

[0036] The driving cylinder 7 19 drives the flap 18 to rotate and press down, the driving cylinder 4 drives the wire pushing column 13 to lift, the driving cylinder 3 drives the positioning ring 10 and the positioning block 9 to lift, and the driving cylinder 5 drives the wire pushing column 13 to translate along the guide groove 15 toward the center of the forming station, pushing the rope 2 against the positioning block 9 and the positioning column 12;

[0037] The driving cylinder 1 6 on the rope pulling device opposite to the wire feed guide assembly drives the mounting plate 5 to translate toward the center of the forming station, and the two wire pulling columns 7 push the rope 2 to translate toward the center of the forming station until the rope 2 rests against the adjacent positioning blocks 9 on both sides, and the driving cylinder 6 17 drives the insertion rod 16 to extend, so that the insertion rod 16 presses the rope 2 against the positioning block 9.

[0038] After the rope 2 is wound, the driving cylinder seven 19 drives the flap 18 to rotate and lift. The worker applies glue to the panel and covers the glued side on the wound rope 2. The driving cylinder eight 21 drives the pressing plate 20 to descend, presses and fixes the panel and the rope 2, then removes the bonded rope 2 and the panel, and finally glues another panel on the other side of the rope 2.
