Description

Technical Field

[0001] This utility model relates to the field of cotton suction flute technology, and in particular to an automated flanging device for cotton suction flute. Background Technology

[0002] The cotton suction tube is a key component used in the textile industry for fine yarn forming. Its function is to reduce yarn hairiness, prevent yarn accumulation leading to increased breakage, and recover unformed yarn for reuse when cotton yarn is twisted and wound into yarn, thereby improving the quality of yarn products.

[0003] The traditional method for flanging flutes involves inserting a flute with a pre-punched round hole into a flanging positioning mandrel. The mandrel has a slot into which a forming block is placed. The forming block has an M10 threaded hole in its center. After the flute is positioned, the M10 stud is manually aligned with the threaded hole on the forming block, and a lever is manually rotated to tighten the stud. The engagement of the threads pulls the forming block out of the flute, simultaneously expanding the round hole and completing the flanging process. This method is inefficient and requires considerable force, making it labor-intensive. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an automated flanging device for cotton suction tubes.

[0005] This utility model is achieved through the following technical solution: An automated flanging device for a flute tube includes a flute tube flanging base plate, a flute tube flanging bottom plate fixed on the flute tube flanging base plate, a flanging rear limiting plate fixed at the rear end of the flute tube flanging bottom plate, a flute tube flanging central spindle and a flanging positioning circular plate installed on the front side of the flanging rear limiting plate, the flute tube flanging central spindle passing through the center of the flanging positioning circular plate; an n-shaped flanging seat fixed at the front end of the flute tube flanging bottom plate, the n-shaped flanging seat being located outside the front end of the flute tube flanging central spindle, a groove being formed on the upper surface of the front end of the flute tube flanging central spindle, a flute tube flanging forming block being arranged in the groove, and an internal threaded hole being formed at the upper end of the flute tube flanging forming block; On the flute flanging base plate, there are strip grooves on the left and right sides of the front end of the base plate. A flanging moving frame is slidably installed in the strip grooves. A flanging motor top plate is provided below the flute flanging base plate. The lower end of the flanging moving frame passes through the flute flanging base plate and is fixedly connected to the flanging motor top plate. A platform servo motor is installed below the flute flanging base plate. The output end of the platform servo motor is connected to the flanging motor top plate through a lead screw assembly. The platform servo motor drives the flanging motor top plate and the flanging moving frame to move up and down. A flanging servo motor is installed at the top of the flanging moving frame. A flanging stud is connected to the lower end of the output shaft of the flanging servo motor. The external thread of the flanging stud matches the internal thread hole on the flute flanging forming block. A through hole is opened at the upper end of the n-shaped flanging seat. The flanging stud, the through hole and the internal thread hole of the flanging forming block are aligned vertically.

[0006] The shape of the upper inner wall of the n-shaped flange seat matches the shape of the flute tube.

[0007] The upper half of the flanged stud is an M6 stud, and the lower half is an M10 stud.

[0008] The left and right ends of the flute tube flange forming block are elliptical.

[0009] The flange positioning plate has waist-shaped holes at its upper and lower ends, and bolt holes corresponding to the waist-shaped holes are opened at its upper and lower ends. The flange positioning plate is fixed to the flange rear limiting plate by bolts. A groove matching the shape of the outer surface of the flute tube is opened in the middle of the flange positioning plate. The mandrel of the flute tube flange passes through the groove in the flange positioning plate and is fixedly connected to the flange rear limiting plate.

[0010] A motor bracket is installed below the base plate of the flute tube flange, and the platform servo motor is mounted on the motor bracket.

[0011] The advantages of this utility model are: 1. This utility model has a high degree of automation, reduces reliance on manual labor, and adopts a dual-motor drive of platform servo motor and flanging servo motor to replace manual pressing or rotation operations, reduce labor costs, and improve work efficiency. The motor is transmitted through mechanical structures such as lead screws and threads, and the action is continuous and can be precisely controlled, avoiding errors and efficiency fluctuations caused by manual operation.

[0012] 2. This utility model has precise positioning and strong processing stability. Multiple positioning structures work together: the flanged back limit plate restricts the rear end position, the flanged positioning round plate's groove fits the flute tube's shape, and the n-shaped flanged seat fixes the front end's outer side, ensuring no displacement during flute tube processing.

[0013] The flanged studs, through holes, and internal threaded holes of the forming block are aligned vertically, and the left and right ends of the forming block are elliptical, which can distribute the force evenly and ensure that the flanged dimensions are consistent and the edges are flat.

[0014] 3. This utility model has two workstations in one device, and one worker can operate both workstations at the same time. The operator only needs to put the flute tube on the mandrel of the flange, which improves efficiency and greatly increases output. Attached Figure Description

Detailed Implementation

[0016] like Figure 1-8 As shown, an automated flute tube flanging device includes a flute tube flanging base plate 1. In practical applications, a support leg is installed under the flute tube flanging base plate 1, a flute tube flanging base plate 2 is fixed on the flute tube flanging base plate 1, a flanging rear limiting plate 3 is fixed at the rear end of the flute tube flanging base plate 2, a flute tube flanging central spindle 4 and a flanging positioning circular plate 5 are installed on the front side of the flanging rear limiting plate 3, and the flute tube flanging central spindle 4 passes through the center of the flanging positioning circular plate 5. An n-shaped flange seat 6 is fixed at the front end of the flute tube flange base plate 2. The n-shaped flange seat 6 is located on the outer side of the front end of the flute tube flange mandrel 4. A groove is opened on the upper surface of the front end of the flute tube flange mandrel 4. A flute tube flange forming block 7 is set in the groove. An internal threaded hole 8 is opened at the upper end of the flute tube flange forming block 7. The flute tube is manually fitted onto the flange mandrel. The hole on the flute tube is pre-processed. After the flute tube is positioned, the hole on the flute tube is aligned with the internal threaded hole 8.

[0017] On the flute flanging base plate 1, there are strip-shaped grooves on the left and right sides of the front end of the flute flanging base plate 2, respectively. A flanging moving frame 9 is slidably installed within these grooves. A flanging motor top plate is located below the flute flanging base plate 1. The lower end of the flanging moving frame 9 passes through the flute flanging base plate 1 and is fixedly connected to the flanging motor top plate. A platform servo motor 11 is installed below the flute flanging base plate 1. The output end of the platform servo motor 11 is connected to the flanging motor top plate via a lead screw assembly 12. The machine 11 drives the top plate of the flanging motor and the flanging moving frame 9 to move up and down. A flanging servo motor 13 is installed at the top of the flanging moving frame 9. The lower end of the output shaft of the flanging servo motor 13 is connected to a flanging stud 14. The external thread of the flanging stud 14 matches the internal thread hole 8 on the flute flanging forming block 7. A through hole is opened at the upper end of the n-shaped flanging seat 6. The flanging stud 14, the through hole, and the internal thread hole 8 of the flanging forming block are aligned vertically. The through hole allows the flanging stud and the flute flanging forming block to pass through. The platform servo motor 11 drives the flanging servo motor 13 and the flanging stud 14 to move up and down. After the flanging stud 14 moves down, it passes through the hole on the flute and matches the internal thread of the internal thread hole 8 of the flute flanging forming block 7. The flanging stud 14 stops moving down and pulls out the flute flanging forming block 7 through the engagement of the threads, achieving the purpose of expanding the round hole of the flute.

[0018] The upper inner wall shape of the n-shaped flange seat 6 matches the shape of the flute tube, resulting in good positioning.

[0019] The upper half of the flanged stud 14 is an M6 stud, and the lower half is an M10 stud.

[0020] The left and right ends of the flute flanging forming block 7 are curved ellipses. It is fixed in place in the groove of the mandrel 4 in the flute flanging center. When the motor drives the flanging stud 14 to rotate forward or backward, the flute flanging forming block 7 will not rotate.

[0021] The flange positioning plate 5 has oblong holes 15 at its upper and lower ends, and the flange rear limiting plate 3 has bolt holes corresponding to the oblong holes 15 at its upper and lower ends. The flange positioning plate 5 is fixed to the flange rear limiting plate 3 with bolts. A groove 16 matching the shape of the flute's outer surface is formed in the middle of the flange positioning plate 5. The flute's flange central shaft 4 passes through the groove 16 on the flange positioning plate 5 and is fixedly connected to the flange rear limiting plate 3. The angle adjustment range is defined by the oblong holes 15 for the bolts. Adjusting to the appropriate angle and tightening the bolts achieves the positioning function.

[0022] A motor bracket 10 is installed below the base plate of the flute flange, and the platform servo motor is installed on the motor bracket 10.

[0023] Initially, the operator inserts the flute into the mandrel 4 of the flute flanging center, using the flanging positioning circle to restrict the position and angle of the flute. At this point, the round hole on the flute aligns with the flute flanging forming block. After positioning, the "start" button is pressed. The platform servo motor 11 rotates the lead screw assembly 12, driving the flanging servo motor 13 and the flanging stud 14 to descend as a whole. Simultaneously, the flanging servo motor 13 (with an M6 stud on the flanging stud 14 screwed into the M6 ​​hole in the center of the motor shaft) begins to rotate slowly, entering the thread finding mode. When the flanging servo motor 13 descends 3mm, the threads of the flanging stud 14 engage with the threads on the flute flanging forming block 7. At this point, the platform servo motor 11 stops running, while the flanging servo motor 13 drives the flanging stud 14 to continue rotating. Through the engagement of the threads, the flute flanging forming block 7 is pulled out. After the flute flanging forming block 7 is pulled out as a whole, the round hole of the flute 17 is fully expanded. At this point, the flanging servo motor 13 stops running. The platform servo motor 11 reverses, raising the entire platform by 3mm, completely disengaging the flute flanging forming block 7 and flanging stud 14 from the flute 17. At this point, the flute flanging is complete, and the flute is manually pulled out. Subsequently, the platform servo motor 11 rotates forward, lowering the entire platform. When the flute flanging forming block 7 falls back into the groove of the flute flanging mandrel 4, the platform servo motor 11 and the flanging servo motor 13 operate simultaneously, retracting the flute flanging forming block 7 back into the groove of the flute flanging mandrel 4. At this point, all components return to their positions, and the system continues to operate after the next workpiece is loaded. This utility model has two workstations in one unit, allowing one worker to operate both workstations simultaneously, improving efficiency and significantly increasing output.
