Description

TECHNICAL FIELD

[0001] The utility model relates to high -speed elbow forming machine technical field especially relates to a kind of pipe clamping knurling mechanism and elbow forming machine for processing straw. BACKGROUND

[0002] The nozzle part of beverage straw is usually provided with a corrugated pipe section that can bend, and users can adjust the angle of the nozzle by bending the corrugated pipe section of the straw, making the posture of drinking beverages more comfortable without moving the cup or box. Chinese patent application publication CN118478563A discloses a straw crimping device for rolling out corrugated pipe sections on multiple straws, which is suitable for mass production.

[0003] The straw crimping device includes a rotating disc that rotates axially, and the rotating disc is provided with a plurality of first clamping structures and second clamping structures for clamping paper straws. The first clamping structure and the second clamping structure each include a fixed clamp block and a movable clamp block, and the fixed clamp block and the movable clamp block are slidingly arranged on a mounting plate. The mounting plate is provided with a cavity that extends through the front and back, and the movable clamp block is provided with a drive arm that extends through the cavity to the back of the mounting plate. The rotating disc is rotatably provided with a plurality of swing arms, one end of the swing arm is slidingly connected with a rotating wheel profile, and the other end of the swing arm is in contact with the drive arm. The swing arm applies a force to the drive arm, and the drive arm drives the movable clamp block to open or close. The mounting plate is provided with an opening and closing cam, and the opening and closing cam has a plurality of first rotating wheel profiles, second rotating wheel profiles, and third rotating wheel profiles with different radii of curvature. The first rotating wheel profile is used to drive the opening of the movable clamp block, the second rotating wheel profile is used to drive the movable clamp block to clamp but not to squeeze the paper straw, and the third rotating wheel profile is used to drive the movable clamp block to clamp the paper straw. The crimping station is provided with a knurling needle, and the outer surface of the knurling needle is provided with a first knurling groove. The two sides of the knurling needle are respectively provided with two knurling wheels, and the two knurling wheels are respectively provided with a second knurling groove that cooperates with the first knurling groove. After the straw is pushed into the knurling needle, the power component drives the first clamping structure and the second clamping structure to continue to rotate, and when it reaches the knurling wheel, the two knurling wheels simultaneously apply a squeezing force to the straw, thereby extruding the required corrugated pipe section on the straw.

[0004] Although the straw crimping device can meet the process requirements of rolling out corrugated pipe sections on straws, the device has a complex structure, and the knurling wheel, the first clamping structure, and the second clamping structure are independently arranged. The drive mechanisms for clamping and knurling need to be arranged separately, and the action coordination between clamping and knurling is prone to delay or asynchronization in the process of high-speed continuous production, which increases the equipment failure rate and requires strict dynamic coordination.
