Description

Technical Field

[0001] The invention relates to the technical field of paper packaging bag processing, in particular to a U-shaped rope making device for a handbag rope threading machine and an automatic rope threading machine. Background Art

[0002] As a common daily and commercial product, handbags or boxes are widely used in customized packaging of holiday gift boxes, high-end goods or clothing; they can also be used in exhibition material bags and derivative packaging of cultural and creative products.

[0003] During the processing of a handbag or a handbox, a U-shaped rope needs to be put on a flat bag body or box body, and the rope is glued and fixed to the bag body or box body by spraying glue, and then folded in half and glued and fixed to form a handbag or a handbox.

[0004] In the traditional U-shaped rope assembly process for handbags or handboxes, the rolled rope needs to be unrolled for transportation and cut into small segments of a set length so that the small segments of rope form a U shape, which is convenient for both ends to pass through the rope holes of the flat bag or box body at the same time. The following technical defects are common in the prior art U-shaped rope production process: (1) When the rope belt is unfolded for conveying, improper design of the tensioning mechanism or drive module may easily cause belt feeding interruption or speed fluctuation, which directly affects production continuity; (2) Existing equipment or manual cutting often results in a length error of more than ±3mm, which cannot meet the consistency requirements of high-end packaging; (3) The existing technology has many defects in accuracy, stability, automation and safety, resulting in low efficiency, large quality fluctuations and high costs in the U-shaped rope forming process.

[0005] In addition, the prior art has the following disadvantages in the assembly process of the U-shaped strap of a handbag or a handbox: (1) The efficiency of manual rope threading is low, the daily average output per person is low, and the rope length tolerance is generally large; (2) The manual gluing process has uneven glue control. Sampling tests show that the gluing strength is insufficient, resulting in a high rate of rope shedding; (3) The positioning accuracy of the rope belt is difficult to guarantee. The length of the rope belt varies during manual operation, resulting in inconsistent left and right heights of the two rope belts after gluing. (4) The existing semi-automatic equipment uses a multi-link adjustment mechanism. When changing product specifications, multiple positioning modules need to be adjusted simultaneously. The debugging takes a long time, and faults such as tape jamming and gluing misalignment are prone to occur during operation, resulting in low overall equipment efficiency.

[0006] Therefore, it is necessary to solve the above technical problems. Summary of the invention

The hook belt rod retracts to avoid interfering with the actions of other mechanisms, thereby ensuring the safety of the equipment.

[0020] A further optimization scheme also includes a rotating rope-taking mechanism, which clamps the two ends of the U-shaped rope respectively, and rotates the two ends 90° respectively, one forward and one reverse, after the U-shaped rope is cut off, so that the length extension direction of the two ends of the U-shaped rope is consistent with the extension direction of the rope threading hole of the plane bag body.

[0021] The rotating rope-taking mechanism is applied to threading a flat rope, and the length extension direction of both ends of the flat rope needs to be consistent with the extension direction of the rectangular rope threading hole of the plane bag body.

Figures 10 to 18 The invention discloses a specific implementation method of a U-shaped rope and strap making device for a handbag rope and strap threading machine.

[0036] like Figure 3 As shown, the plane bag body A is provided with four rectangular rope holes A1 and four pressing parts A2. The four rope holes A1 are divided into two groups, and each group is provided with a rope. Figure 5 For the U-shaped rope B shown, glue is sprayed on every two pressing parts A2. Figure 5 The middle pressure rope closing belt B1 section passes through the rope threading hole A1 and lies flat on the Figure 3 The pressed part A2 is adhered and fixed to the flat bag body A by glue.

[0037] like Figure 1 and Figure 2 As shown, the automatic rope threading machine of this embodiment includes a frame 700, on which a rope conveying mechanism 100, a U-shaped rope forming mechanism 200 and a rope threading mechanism 300 are provided; the rope conveying mechanism 100 pulls the rolled rope B apart and places the head section horizontally (such as Figure 7 The U-shaped rope forming mechanism 200 clamps the rope head end and pulls the rope down into a U shape (such as Figure 4) to a set length and then cut off; the rope threading mechanism 300 clamps the two ends of the U-shaped rope B respectively and conveys it to the bottom of the flat bag body A, so that the two ends of the U-shaped rope B are aligned and pass through the two rope holes A1 of the flat bag body A. The rope conveying mechanism 100 and the U-shaped rope forming mechanism 200 constitute a U-shaped rope making device of a handbag rope threading machine.

[0038] The above-mentioned automatic rope threading machine is used to thread ropes on the plane bag body A. Four rope threading holes A1 are pre-punched on the plane bag body A. Two groups of U-shaped ropes are threaded on each of them. The rope threading mechanism 300 clamps the two ends of the U-shaped rope respectively, and the rope section exposed at the head has a set length, such as Figure 5 The compression cord B1 shown is passed through the cord threading hole A1.

[0039] The automatic rope threading machine uses a rope conveying mechanism 100, a U-shaped rope forming mechanism 200 and a rope threading mechanism 300 to automatically convey, cut and position the rope to the rope threading hole A1, thereby achieving high production efficiency and reducing product costs; significantly improving the consistency of the rope length of handbag products and improving product quality.
