Embodiment 1

[0045] Such as figure 1 As shown, the stretching device for tubular objects in this embodiment includes a vertically arranged first support plate 1; the first support plate extends horizontally outward to form a second support plate 2;

[0046] The top of the first support plate 1 is provided with a fixed wide arm 3; the extension end of the second support plate 2 is movably connected with a bent plate 5 through a shaft pin 6; the bent plate is composed of two straight plates at a certain angle; The pivot pin is located at the junction of the two straight plates of the bent plate 5; the top end of the bent plate 5 is provided with a movable wide arm 4, and the bottom end conflicts with a vertically arranged elastic structure 10;

[0047] When the bottom end of the curved plate 5 is not subjected to downward external force, the amount of compression of the elastic structure 10 is the smallest, and the movable wide arm 4 and the fixed wide arm 3 are at the same horizontal height...

Embodiment 2

[0056] On the basis of the first embodiment, the device for stretching tubular objects in this embodiment is further composed of a first straight plate and a second straight plate connected to each other to form a right angle. That is, the angle formed by the two straight plates is 90°.

[0057] Further, a suspension ring 7 is connected to the end of the second straight board away from the first straight board; the suspension ring 7 is connected to a pedal 9 through a rope 8 .

[0058] During operation, the pedal 9 moves up and down by an external force, thereby pulling the rope 8 and the suspension ring 7 to move up and down, thereby pulling the second straight board to move downward. When the second straight board moves downward, the elastic structure 10 is compressed, and the first straight board moves downward. The shaft pin 6 rotates to the right as the rotation point, and during the rotation, the movable stretching arm 4 moves to the right away from the fixed stretching ...

no. 1 example

[0062] Such as image 3 As shown, the tubular object folding machine in this embodiment includes any one of the tubular object stretching devices described in Embodiment 1 to Embodiment 2, a stretching tube, and a movable press arranged at the upper end of the tubular object stretching device. edge device;

[0063] The stretched wide tube is composed of two semicircular first stretched wide tube walls 31 and a second stretched wide tube wall 41; the first stretched wide wall 31 is located on the outside of the fixed stretched wide arm 3; The second widening tube wall 41 is located on the outside of the movable widening arm 4;

[0064] The upper edge of the first widened tube wall 31 is higher than the top of the fixed widened arm 3; the upper edge of the second widened tube wall 41 is higher than the top of the movable widened arm 4;

[0065] Wherein, the movable edge-holding device moves downward to press the part of the tubular object that is sleeved on the outside of the ...

Abstract

The invention discloses a widening device, and a flanging machine of tubular objects. The widening device comprises a vertically arranged first supporting plate; the first supporting plate is extended outward horizontally so as to form a second supporting plate; the top of the first supporting plate is provided with a fixed widening arm; the extended end of the second supporting plate is flexibly connected with a bending plate via an axle pin; the bending plate is composed of two straight plates arranged with a certain angle; the axle pin is arranged on a connection part of the bending plate with the two straight plates; the top of the bending plate is provided with a movable widening arm, and the bottom is pressed against a vertically arranged elastic structure. The flanging machine comprises the widening device, widening tubes, and a movable flange fixing installation arranged on the upper end of the widening device; the widening tube is composed of a first widening wall and a second widening wall which are both semicircle in shape; the first widening wall is arranged on the outer side of the fixed widening arm, and part of the first widening wall is higher than a first widening tube; and the second widening wall is arranged on the outer side of the movable widening arm, and part of the second widening wall is higher than a second widening tube.

Description

technical field [0001] The invention relates to a tubular object stretching device and a tubular object folding machine. Background technique [0002] In existing tubular fabrics, especially tubular fabrics with a smaller inner diameter, the hemming work of the two ports is all done by hand during the production process. There are the following problems in purely manual work: [0003] 1: Low work efficiency; [0004] 2: The hemming is not neat enough, the size is not accurate enough, the product quality varies from person to person, and the quality is unstable; [0005] 3: The labor intensity of workers or processors is high. Contents of the invention [0006] In order to overcome the above problems, the present invention provides a tubular object stretching device and a tubular object folding machine with simple structure, high working efficiency and easy operation. [0007] To achieve the above purpose, the device for stretching tubular objects of the present inventi...
