Fig. 1 shows an external form of a tube rolling apparatus, which includes a housing 1, a rolled tube 2 is received in the housing 1, and one end of the tube 2 is exposed from the housing 1 for pulling out the rest of the tube 2.

Fig. 2 shows the internal structure of the roller tube machine, the housing 1 is hidden in fig. 2, and the locking structure of the roller tube machine is omitted, and only the hub 4 and the tube discharging device 3 are shown. As shown in fig. 2, the pipe roller further includes a hub 4 and a pipe discharge device 3 provided in the housing 1, and further includes a coil spring not shown in the drawing. The hub 4 is rotatably arranged in the housing 1, the hub 4 being centrally provided with a spindle, not shown, which spindle is provided with a feed opening and a discharge opening according to known techniques, the starting end of the tube 2 being connected to the discharge opening and being led out from the interior of the hub 4 to the hub surface of the hub 4. The starting position of the tube 2 on the hub surface of the hub 4 is clearly visible in fig. 6.

With continued reference to fig. 2, the hub 4 includes two spaced apart

spokes

41, 42 with a hub barrel 43 disposed between the two

spokes

41, 42, the hub barrel 43 being divided into a first hub barrel 431 and a second hub barrel 432. As shown in fig. 6, the starting position of tube 2 on the surface of hub 43, from which winding of first hub 431 is initiated, is at a position on first hub 431 adjacent to second hub 432. The outer diameter of the first hub 431 is less than the outer diameter of the second hub 432 by an outer diameter substantially equal to the first layer height of the tube 2 after retraction of the first hub 431. The second hub 432 is configured as a coil spring seat for storing coil springs, and when the coil winder is designed, the diameter of the coil spring seat for storing energy is required, and when the diameter of the coil spring seat is designed to be too large, space is wasted, and when the diameter of the coil spring seat is too small, limited energy storage and discontinuous and unbalanced energy release can be caused. During design, the outer diameter of the coil spring seat, i.e., the second hub 432, is determined and then the outer diameter of the first hub 431 is determined. As will be described later, in conjunction with the tube-discharging function of the tube-discharging device 3, the space formed by the radial difference between the first hub 431 and the second hub 432 can be effectively utilized, and the effect of reducing the volume and not reducing the winding performance (winding strength, length of the wound tube) can be achieved.

With continued reference to figures 2 and 6, the difference d between the outer diameters of the first and

second hubs

431, 432 is close to the diameter of the tube 2 and during actual furling the tube 2 is slightly compressed, the difference d being determined by the height of the first layer of the tube 2 after it has been furled.

The pipe-arranging device can be realized by adopting the prior art. To illustrate, as shown in fig. 2 and 3, the pipe discharging device 3 includes a bidirectional screw 31 and a pipe rack 32, the pipe rack 32 includes a rack body 321, a reversing block 322 and a rack cover 323, the rack body 321 has a through hole 3210 at an upper end thereof, the reversing block 322 is sleeved on the bidirectional screw 31 through the through hole 3210, the reversing block 322 has a threaded portion 3220, the reversing block 322 is inserted from a top of the rack body 321, the threaded portion 3220 is engaged with one of the threads of the bidirectional screw 31, a top of the reversing block 322 is covered by the rack cover 323, two sides of the rack cover 323 have connecting holes 3230, a fastening rack 324 passes through the connecting holes 3230 and is connected with the connecting holes at two sides of the top of the rack body 321, the rack cover 323 is fastened at the top of the rack body. When the bidirectional screw 31 is rotated, the rake 32 is linearly moved by the principle of screw drive. The range of linear movement of the rake 32 is limited by the distance separating the two spokes 41, and when the rake 32 moves to the end of one of the flights of the two-way screw 31, it automatically switches to engagement with the other flight and is driven by the other flight to move in the opposite direction.

As shown in fig. 4 to 6, the rake 32 has an initial position on the bidirectional screw 31, which is indicated by the triangle T1 in fig. 6, in which the bidirectional screw 31 is arranged to allow the tube 2 to start to wind around the first hub 431 at a position where the first hub 431 abuts the second hub 432, forcing the rake 32 to move axially away from the second hub 432. The arrow a1 shows the direction of movement of the rake 32, which is determined by the handedness of a flight in the two-way screw 31, at which stage the diverter block 322 of the rake 32 engages a flight of the two-way screw 31, the handedness of which is such that the rake 32 can only move to the left.

Returning to fig. 2, the spoke 42 has an opening, which is sealed by a coil spring cover 44, a pulley 34 is disposed on the coil spring cover 44, and the pulley 34 is connected with the bidirectional screw 31 through a timing belt 33, i.e. the pulley 34 can drive the bidirectional screw 31 to rotate. The bidirectional screw 31 is rotatably mounted on the housing 1, the pulley 34 is fixed to the wrap spring cover 44, the wrap spring cover 44 is fixed to the spoke 42, and the hub 4 is rotatably mounted on the housing 1. When the pipe 2 is pulled out, the pipe 2 pulls the hub 4 to rotate, the hub 4 further drives the belt wheel 34, the belt wheel 34 further drives the bidirectional screw 31, the bidirectional screw 31 further drives the pipe rack 32, and the pipe 2 sequentially separates from the hub 4 layer by layer. Similarly, when the pulled-out pipe 2 needs to be wound, under the spring force of the coil spring, the hub 4 rotates reversely, which drives the belt wheel 34 to rotate reversely, and then drives the bidirectional screw 31 to rotate, and the bidirectional screw 31 drives the pipe rack 32, and the pipe is wound on the hub 4 layer by layer. Fig. 4 to 8 show the condition in which the pulled-out tube 2 is wound, the tube 2 is wound from the initial position and moved leftward by the rake 32 while being wound around the hub 4, which causes the tube 2 to be wound around the first hub 431. Fig. 7 shows a state where the first layer is wound on the first hub 431. In the position shown by the triangle T2 in fig. 8, the tube 2 is wound up during the driving of the hub 4 by the coil spring in the direction of the arrow a2 to form a second layer of tubes, which are wound around the first layer of tubes and the second hub 432, the first layer of tubes and the second hub 432 are close in height to allow the first layer of tubes on the first hub 431 and the outer peripheral surface of the second hub 432 to be consecutively gauntlet-off, said close comprising the same or a slight difference in height, but not affecting the uniform gauntlet-off and the uniform gauntlet-off of the gauntlet-off device 3. The location of the row of tubes of the first layer is on the first hub 431 and the location of the row of tubes of the second layer is on the outer peripheral surfaces of the first layer of tubes and the second hub 432. After the pipe rack 32 reaches the right side, the bidirectional screw 31 continues to rotate, the pipe rack 32 changes the moving direction, the pipe rack continues to evenly arrange the pipes, and then the pipe rack 32 moves back and forth according to the above rule until the pipe 2 is arranged in the pipe arranging space of the hub 4, at this time, the state shown in fig. 1 is reached, the end part of the pipe 2 is provided with a stop ball which is not shown in the figure, the shape and the size of the stop ball are larger than the hole which is formed in the pipe rack 32 and allows the pipe 2 to pass through, the stop ball cannot pass through the pipe 2, therefore, the tail end of the pipe 2 is kept outside the shell 1, and the coil spring cannot rotate the hub 4 any.

In fig. 9, the hub on the left side is similar to the hub of the previous embodiment, and the hub on the right side is shown as a comparative example. Fig. 10 shows a hub as another comparative example. Set for the basis the utility model discloses a coil spring seat size of two kinds of wheel hub structures of wheel hub structure and comparative example is unanimous, and wheel hub structure is around pipe width W, and wheel hub diameter H homogeneous is sent, can observe from the picture:

1. compared with the structure of the comparative example in fig. 9, the utility model has the advantages that the winding space is increased, and the winding is directly represented as a pipe layer with more than one layer, such as the pipe layer shown in bold in fig. 9;

2. compared with the structure of the comparative example shown in fig. 10, the utility model discloses casing width W1 is obviously less, and the reelpipe ware volume is less. In addition, the coil spring of the comparative example shown in fig. 10 has a weak energy storage effect, and the actual winding length is not ideal.

Furthermore, there is also a hub structure which is similar to the hub structure of the previous embodiment, however it is not combined with the tube discharging device, for example, the initial tube discharging position of the tube discharging device is located at one end side of the hub, not at the adjacent position of the two hubs, which also results in that the space of the outer peripheral surface of the first hub 431 is not effectively utilized.

In one embodiment, the axial length of the first hub 431 is greater than the axial length of the second hub 432. Particularly, when the axial length of the first hub 431 is more than 1.5 times the axial length of the second hub 432, the volume of the tube rolling machine can be obviously reduced.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention, all without departing from the content of the technical solution of the present invention, fall within the scope of protection defined by the claims of the present invention.
