Description

Technical Field

[0001] The utility model relates to the technical field of rope and belt processing, in particular to a riveting and cutting mechanism. Background Art

[0002] Handbags are widely used in daily life because they are easy to carry. Handbags usually include a bag body and two handles connected to the bag body. The two ends of the handles have clamps. The handles with clamps are inserted into the bag body so that the two are not easily separated. The existing clamps are divided into plastic clamps and metal clamps. The metal clamps need to be wrapped outside the plastic clamps. The announcement number is CN215051586 U's patent document discloses a gift bag rope riveting machine, including a rubber-coated structure and an iron-coated sheet structure, which can be applied to a metal chuck, wherein the iron-coated sheet structure includes a mounting plate, a support cylinder is provided on one side of the mounting plate and at one end close to the rubber-coated structure, a limiting block 1 is connected to the output shaft of the support cylinder and a limiting through hole is provided on the limiting block 1, a lifting cylinder is provided on the end of the mounting plate away from the limiting block 1 and at the upper part, an iron-coated head is installed on the output shaft of the lifting cylinder, a guide groove body is provided at the upper end of the support frame 1 and the lower part of the iron-coated head, a support base is slidably provided in the guide groove body, an adjusting cylinder is provided on one side of the guide groove body, the telescopic shaft of the adjusting cylinder is connected to the support base, a guide rod is provided between the support frame 1 and the support frame 2, a threaded rod is provided in the guide rod, and a sliding rod is slidably provided on the guide rod The movable block and the sliding block are threadedly connected with the threaded rod. One end of the guide rod is provided with a motor to drive the threaded rod to rotate. The lower end of the sliding block is provided with a clamping structure. The upper end of the support frame and the support base are provided with an iron sheet conveying structure on the side away from the adjusting cylinder. The iron sheet conveying structure includes two relatively arranged conveying guide grooves. The conveying guide groove is provided with a limiting groove body near the end of the support base. One end of the limiting groove body is provided with a conveying cylinder and the telescopic shaft of the conveying cylinder is connected with a conveying block slidably arranged in the conveying guide groove. The adjusting cylinder pushes the support base to approach the iron sheet conveying structure, and the conveying guide groove is connected with the vibration plate to convey the iron sheet. The two conveying guide grooves convey the iron sheet to the corresponding placement grooves. The support base is recovered in the same straight line as the bag rope, and the front end of the bag rope is transported to the placement groove set at the front end for iron sheet wrapping operation.

[0003] The above-mentioned iron sheet structure has the following defects in the actual production process: the support base is slidably arranged in the guide groove body, the adjusting cylinder pushes the support base close to the iron sheet conveying structure, the iron sheet is conveyed from the vibration plate to the conveying guide groove, and the iron sheet is then conveyed from the conveying guide groove to the placement groove. Combined with Figure 6 of the specification in the patent document, it can be seen that when the iron sheet is placed in the placement groove, when the support base moves and resets in the guide groove body, the iron sheet is easy to fall with the movement of the support base, affecting the normal operation of the iron sheet structure.
