Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thin-walled tube processing, in particular to a thin-walled tube winding machine. Background Art
[0002] Polytetrafluoroethylene thin-walled tube (PTFE thin-walled tube) is a kind of tube with excellent chemical stability, high temperature resistance and corrosion resistance. It is usually made of polytetrafluoroethylene resin through extrusion, calendering or molding and other processing techniques. It is widely used in chemical, electronic, medical, aerospace and other fields for conveying various corrosive media, high temperature media, electrical insulation and other occasions.
[0003] In the production line of thin-walled tubes, the extruder and the etching machine are usually set up next to each other. The raw materials are first extruded into thin-walled tubes by the extruder, and then the etching machine etches the thin-walled tubes in time. Due to the high extrusion speed of the extruder, a large number of thin-walled tubes need to be extruded for long-term orders. However, etching will be performed immediately after extrusion, which will produce a large number of etched tubes. The storage time of etched tubes is short, and the bonding performance of etched tubes that have been stored for a long time will be affected. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figure 1 As shown, the utility model provides a thin-walled tube winding machine, which is suitable for a thin-walled tube production line. The thin-walled tube production line includes an extruder 1, an etching machine is arranged on one side of the extruder 1, and a traction machine 2 and a winding system 3 are arranged between the extruder 1 and the etching machine.
[0023] Specifically, Figure 2As shown, the winding system 3 includes a chassis 31, and a motor 32 is arranged in the chassis 31. A baffle 33 is fixedly installed at the output end of the motor 32. A reel 34 is clamped on the baffle 33. The cross-section of the reel 34 is elliptical. A slot matching the shape of the reel 34 is provided on the baffle 33. A baffle 33 is arranged at each end of the reel 34. The two baffles 33 can prevent the thin-walled tube wound by the reel 34 from detaching. The thin-walled tube wound on the reel 34 can be removed by removing the baffle 33 at one end of the reel 34 away from the motor 32.
[0024] In this embodiment, a reel 34 with an elliptical cross-section is used. On the one hand, the space occupied by the rolled thin-walled tube roll can be made smaller, which is convenient for collection and not prone to rolling during storage. On the other hand, the reel 34 can be more firmly connected to the baffle 33, so that when the baffle 33 rotates, it can drive the reel 34 to rotate synchronously, thereby achieving a limiting effect.
[0025] like Figure 2-Figure 3 As shown, the winding system 3 is connected to the tube pressing device 4, and the tube pressing device 4 includes a fixed rod 41, which is fixedly installed on the chassis 31, and the fixed rod 41 is rotatably connected to the rotating rod 42. A torsion spring is arranged between the fixed rod 41 and the rotating rod 42, and a fitting portion 43 is arranged on the rotating rod 42. The rotating rod 42 is rotatably connected to a pressure roller 44, and the pressure roller 44 and the fitting portion 43 are both fitted to the reel 34, so that when the reel 34 reels the thin-walled tube, the thin-walled tube is pressed tightly by the pressure roller 44, and the reel is rolled more densely, thereby improving the reeling effect, and the pressure roller 44 can press the thin-walled tube to be straightened and rewound, thereby reducing the creases generated on the thin-walled tube when reeling.
[0026] In the present application, the thin-walled tube extruded by the extruder 1 is first pulled into the winding system 3 by the traction machine 2, and the motor 32 drives the baffle 33 to rotate, and the baffle 33 drives the reel 34 to rotate, and the rotating reel 34 reels the thin-walled tube. During the reeling process, the pressure roller 44 presses the thin-walled tube, and the reeling thickness of the thin-walled tube gradually increases. The torsion spring arranged between the fixed rod 41 and the rotating rod 42 can make the position of the pressure roller 44 adapt to the reeling thickness and reeling shape of the thin-walled tube. After the reeling is completed, the thin-walled tube is removed from the reel 34 for collection. When etching is required, the reeled thin-walled tube is processed into an etched tube by the etching machine. It can be used immediately without immediately etching the thin-walled tube extruded by the extruder 1, so as to avoid affecting the bonding performance of the etched tube due to the long storage time of the etched tube.
[0027] Working principle: the thin-walled tube extruded by the extruder 1 is first pulled into the winding system 3 by the traction machine 2, the motor 32 drives the baffle 33 to rotate, the baffle 33 drives the reel 34 to rotate, and the rotating reel 34 reels the thin-walled tube. During the reeling process, the pressure roller 44 presses the thin-walled tube. After the reeling is completed, the thin-walled tube is taken off the reel 34 for collection. When etching is required, the rolled thin-walled tube is processed into an etched tube by the etching machine, which is ready for use.
[0028] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
