[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Combine the following Figures 1 to 5A coil device provided in an embodiment of the present invention is described. The coil device provided in this embodiment comprises: a support 1, an introduction wheel mechanism, a reversing wheel mechanism and an output wheel mechanism, and is used for coiling metal pipes such as copper pipes or steel pipes.

[0034] Among them, the introduction wheel mechanism, the reversing wheel mechanism and the export wheel mechanism are all arranged on the support 1; there is a first passing gap for the pipe to pass through between the introduction wheel mechanism and the reversing wheel mechanism, and there is a second passing gap for the pipe to pass through between the export wheel mechanism and the reversing wheel mechanism; wherein the introduction wheel mechanism is adjustable in radial position so that the first passing gap is adjustable, and the introduction wheel mechanism is used to introduce the pipe in the first direction; the export wheel mechanism is adjustable in radial position so that the second passing gap is adjustable, and the export wheel mechanism is used to spirally export the pipe in the second direction; the reversing wheel mechanism is arranged between the introduction wheel mechanism and the export wheel mechanism, and is used to convert the travel trajectory of the pipe from the first direction to the second direction.

[0035] It can be seen from the above scheme that compared with the prior art, in the present invention, when performing coiling operations, the pipe is introduced along the first direction through the introduction wheel mechanism, the travel trajectory of the pipe is converted from the first direction to the second direction through the reversing wheel mechanism, and then the pipe is spirally led out along the second direction through the export wheel mechanism to form a spiral shape. The device is easy to use. Since the travel trajectory of the pipe is fixed, the diameter of the exported coil is uniform and controllable. Moreover, since the introduction wheel mechanism and the export wheel mechanism can be movably arranged on the support 1, the first passing gap between the introduction wheel mechanism and the reversing wheel mechanism, as well as the second passing gap between the export wheel mechanism and the reversing wheel mechanism can be adjusted, which can adapt to pipes of different diameters and improve the versatility and standardization of the coil.

[0036] In this embodiment, the first direction may be a horizontal direction, and the second direction may be inclined upward along an arc trajectory. After the pipe enters the second direction, a spiral coil may be formed.

[0037] The above-mentioned lead-out wheel mechanism is adjustable in radial position and can also be used to adjust the second direction. By adjusting the position of the lead-out wheel mechanism relative to the reversing wheel mechanism, the lead-out trajectory of the pipe is changed to adjust the diameter of the spiral coil.

[0038] Furthermore, the axial position of the guide wheel mechanism is adjustable, so that the axial distance between the pipe passing through the mechanism and the support can be adjusted, which can be used to adjust the pitch of the spiral coil.

[0039] In a specific embodiment, the introduction wheel mechanism includes a first slider 2, a support 1 is provided with a first connecting structure 11, the first slider 2 is slidably connected to the first connecting structure 11, the first slider 2 is rotatably connected to a first guide wheel 21, the first guide wheel 21 is provided with a first guide structure 211, the first guide structure 211 is in contact with the pipe fitting, and is used to drive the pipe fitting to move along the first direction through the rotation of the first guide wheel 21.

[0040] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the export wheel mechanism includes a second slider 3, and the support 1 is provided with a second connecting structure 12. The second slider 3 is slidably connected to the second connecting structure 12. The second slider 3 is rotatably connected to the second guide wheel 31, and the second guide wheel 31 is provided with a second guide structure 311. The axial spacing between the second guide structure 311 and the support 1 is greater than the axial spacing between the first guide structure 211 and the support 1, so that the pipe fitting forms an unclosed circle after winding a circle, and is finally exported to form a spiral shape. The second guide structure 311 is in contact with the pipe fitting, and is used to drive the pipe fitting to move along the second direction through the rotation of the second guide wheel 31.

[0041] Alternatively, if Figure 1 and Figure 5 As shown, the first connecting structure 11 is a first through hole arranged on the support 1, and the second connecting structure 12 is a second through hole arranged on the support 1. The two through holes are arranged at intervals in the horizontal direction. The shapes of the first through hole and the second through hole can be rectangular holes or waist-shaped holes. The first slider 2 is installed in the first through hole and slidably cooperates with the first through hole, so that the first slider 2 can be lifted and lowered in the height direction. The second slider 3 is installed in the second through hole and slidably cooperates with the second through hole, so that the second slider 3 can be lifted and lowered in the height direction.

[0042] Reference Figure 3 Furthermore, a limiting plate 22 is provided at one or both ends of the first slider 2, and the width of the limiting plate 22 is greater than the width of the first through hole, which can prevent the first slider 2 from detaching from the first through hole during the lifting process. A limiting plate 22 is also provided at one or both ends of the second slider 3, and the width of the limiting plate 22 is greater than the width of the second through hole, which can prevent the second slider 3 from detaching from the second through hole during the lifting process.

[0043] Furthermore, the first connection structure 11 may also be a first slide rail provided on the surface of the support 1, the first slide rail is provided along the height direction, the first slider 2 is connected with the first slide rail in cooperation, and can perform lifting and lowering motion along the height direction of the support 1. The second connection structure 12 may also be a second slide rail provided on the surface of the support 1, the second slide rail is provided along the height direction, the second slider 3 is connected with the second slide rail in cooperation, and can perform lifting and lowering motion along the height direction of the support 1.

[0044] In this embodiment, a first positioning structure is arranged between the support 1 and the first slider 2, and is used to fix the first slider 2 on the support 1 after movement; wherein, the first positioning structure can be a bolt, a positioning pin, etc., by setting a plurality of first positioning holes on the first slider 2 or the limiting plate 22, and setting a plurality of second positioning holes on the support 1 along the movement direction of the first slider 2, when the first slider 2 moves, the screws are inserted into the first positioning holes and the second positioning holes in sequence to fix the first slider 2 on the support 1; or, the first positioning structure is a screw, and a plurality of threaded holes are only arranged on the first slider 2 or the limiting plate 22, and when the first slider 2 moves, the screws are screwed into the threaded holes to tighten the support 1, and the first slider 2 is fixed to the support 1.

[0045] Furthermore, the support 1 is provided with a lead screw along its height direction, the top end of the lead screw is threadedly connected to the top of the support 1, and the bottom end of the lead screw is connected to the top of the first slider 2. When the first slider 2 is raised or lowered, the circular motion is converted into the linear motion of the first slider 2 by rotating the lead screw, thereby driving the first slider 2 to perform the lifting motion, and due to the threaded connection between the support 1 and the lead screw, it can also play a role in positioning the first slider 2 after the first slider 2 stops moving.

[0046] A second positioning structure is provided between the support 1 and the second slider 3, and is used to fix the moved second slider 3 on the support 1. The second positioning structure is similar to the first positioning structure, and will not be described in detail.

[0047] like Figure 1 and Figure 3 As shown, the reversing wheel mechanism includes a reversing wheel 4, which is rotatably connected to the support 1. The reversing wheel 4 is provided with a third guide structure 41. The distance between the third guide structure 41 and the first guide structure 211 is a first passing gap. When the pipe passes through the first passing gap, the pipe is clamped between the third guide structure 41 and the first guide structure 211. When the first direction is a horizontal direction, the first passing gap can be the distance between the first guide structure 211 and the third guide structure 41 in the vertical direction; the distance between the third guide structure 41 and the second guide structure 311 is a second passing gap. When the pipe passes through the second passing gap, the pipe is clamped between the third guide structure 41 and the second guide structure 311. The third guide structure 41 is used to squeeze and guide the pipe to deform it and enter the second guide structure 311, so as to convert the travel trajectory of the pipe from the first direction to the second direction.

[0048] With such arrangement, the pipe is bent between the third guide structure 41 and the second guide structure 311, and the direction of travel is changed from the first direction to the second direction. The pipe is led out to the spiral coil by the drive of the second guide structure 311. During this process, the third guide structure 41 mainly serves to transport the pipe to the second guide structure 311, and pressure is provided above the pipe so that the pipe is bent upward under the action of the third guide structure 41. The distance between the first guide structure 211 and the third guide structure 41 is adjusted according to the diameter of the pipe to enable pipes of different diameters to be introduced, and the pipe is led out by adjusting the distance between the second guide structure 311 and the third guide structure 41.

[0049] Reference Figure 2 and Figure 4 In this embodiment, the first guide structure 211 is an annular groove arranged on the outer circumferential surface of the first guide wheel 21, the second guide structure 311 is an annular groove arranged on the outer circumferential surface of the second guide wheel 31, and the third guide structure 41 is an annular groove arranged on the outer circumferential surface of the reversing wheel 4.

[0050] In this way, by respectively providing annular grooves on the first guide wheel 21, the second guide wheel 31 and the reversing wheel 4, the pipe can be embedded in the respective annular grooves during its movement, ensuring that the pipe will not deviate from the movement track, thereby achieving axial limitation of the pipe.

[0051] When the present invention is in use, the second guide wheel 31 is first lowered, so that the pipe fitting is sequentially loaded into the annular groove of the first guide wheel 21, the annular groove of the second guide wheel 31 and the annular groove of the reversing wheel 4, wherein the pipe fitting is located at the top of the first guide wheel 21 and the second guide wheel 31, and is used to carry the pipe fitting, and the reversing wheel 4 is located above the pipe fitting, and then the second guide wheel 31 is raised, so that the pipe fitting is deformed and bent upward between the reversing wheel 4 and the second guide wheel 31, and then with the rotation of the first guide wheel 21, the reversing wheel 4 and the second guide wheel 31, the pipe fitting moves successively along the first direction and the second direction, and finally the pipe fitting is processed into a spiral shape, during which the single-turn diameter of the formed spiral pipe fitting can be changed by changing the height of the second guide wheel 31.

[0052] In a specific embodiment of the present invention, the import wheel mechanism also includes a first rotating shaft 23, which is rotatably connected to the first slider 2, one end of the first rotating shaft 23 is connected to the first guide wheel 21, and the other end of the first rotating shaft 23 is connected to a first driving device, and the first driving device is used to rotate the first guide wheel 21 by driving the first rotating shaft 23; the export wheel mechanism also includes a second rotating shaft 32, which is rotatably connected to the second slider 3, one end of the second rotating shaft 32 is connected to the second guide wheel 31, and the other end of the second rotating shaft 32 is connected to a second driving device, and the second driving device is used to rotate the second guide wheel 31 by driving the second rotating shaft 32, and the rotation directions of the first rotating shaft 23 and the second rotating shaft 32 are the same.

[0053] With such arrangement, the first guide wheel 21 and the second guide wheel 31 can rotate in the same direction respectively under the action of their respective corresponding driving devices. The driving devices can be motors to achieve automatic rotation, or they can be rockers 6 respectively arranged on the first guide wheel 21 and the second guide wheel 31, which can be rotated respectively by manually driving the rockers 6.

[0054] In a specific embodiment of the present invention, Figure 5 As shown, the first driving device includes a first driving wheel 24, and the first driving wheel 24 rotates synchronously with the first guide wheel 21; the second driving device includes a second driving wheel 33, and the second driving wheel 33 rotates synchronously with the second guide wheel 31, and the first driving wheel 24 and the second driving wheel 33 are connected by transmission member 5. For example, the first guide wheel 21 and the second guide wheel 31 are sprocket wheels, and the transmission member 5 is a chain, or the first guide wheel 21 and the second guide wheel 31 are pulleys, and a belt drive is adopted. The rocker 6 can be used to drive the first guide wheel 21 or the second guide wheel 31 to realize manual drive, or the first guide wheel 21 or the second guide wheel 31 can be driven by a motor.

[0055] Optionally, the reversing wheel mechanism includes a fixed shaft 42, which is rotatably connected to the support 1, one end of the fixed shaft 42 is connected to the reversing wheel 4, and the other end of the fixed shaft 42 is connected to a third driving device, which is used to drive the fixed shaft 42 to rotate. The third driving device can be the same as the first driving device mentioned above.

[0056] like Figure 5 As shown, the third driving device includes a third driving wheel 43, and the third driving wheel 43 rotates synchronously with the reversing wheel 4. For example, the reversing wheel 4 is a sprocket, which can be driven by the chain between the first guide wheel 21 and the second guide wheel 31, so that the first guide wheel 21 and the second guide wheel 31 have the same direction, and the reversing wheel 4 and the first guide wheel 21 have opposite directions. Of course, the reversing wheel 4 can also be driven by the pipe during the movement of the pipe and passively rotate.

[0057] Preferably, the travel speed of the pipe is the same as that of the chain, that is, during operation, the radial distance from the axis of the first rotating shaft 23 to the chain is the same as the radial distance from the axis of the first rotating shaft 23 to the pipe, the radial distance from the axis of the second rotating shaft 32 to the chain is the same as the radial distance from the axis of the second rotating shaft 32 to the pipe, and the radial distance from the axis of the fixed shaft 42 to the chain is the same as the radial distance from the axis of the fixed shaft 42 to the pipe. Thus, the pipe and the first guide wheel, the second guide wheel and the reversing wheel will not move relative to each other to generate friction.

[0058] In a specific embodiment of the present invention, the first guide wheel 21 is detachably connected to the first rotating shaft 23, and the second guide wheel 31 is detachably connected to the second rotating shaft 32. For example, the first guide wheel 21 is clearance-fitted with the first rotating shaft 23 and connected by a key, the second guide wheel 31 is clearance-fitted with the second rotating shaft 32 and also connected by a key, and the reversing wheel 4 is also clearance-fitted with the fixed shaft 42 and connected by a key. With such an arrangement, the first guide wheel 21 and the second guide wheel 31 of different diameters can be replaced according to the different diameters of the pipe fittings, and the first passing gap and the second passing gap can also be changed, so that pipe fittings of different diameters can be processed, thereby improving the versatility of the present invention.

[0059] Preferably, a spacing adjustment structure is provided between the second guide wheel 31 and the second rotating shaft 32 for adjusting the axial spacing between the second guide wheel 31 and the support 1. For example, the spacing adjustment structure may be a gasket, and the distance between the second guide wheel 31 and the support 1 is increased by increasing the number of gaskets, thereby adjusting the pitch of the spiral pipe.

[0060] like Figure 1 , Figure 4 and Figure 5As shown, a coil device provided in this embodiment is convenient to use and small in size. It can be used to process small-diameter copper tubes and can meet the demand for copper tubes for heat exchangers. The second guide wheel 31 is rotated by manually driving the rocker 6, and the first guide wheel 21 is driven to rotate under the transmission of the chain. The reversing wheel 4 also starts to rotate under the drive of the chain. When the coil operation is performed, the pipe is introduced along the first direction through the rotation of the first guide wheel 21, and is bent here after passing through the reversing wheel 4. Then, the moving trajectory of the pipe is converted from the first direction to the second direction, and enters the annular groove of the second guide wheel 31. 1 is rotated in the second direction to spirally guide the pipe fittings. Since the first slider 2 and the second slider 3 are both movably arranged on the support 1, the first passing gap between the first guide structure 211 and the third guide structure 41 can be adjusted, and the second passing gap between the second guide structure 311 and the third guide structure 41 can be adjusted, so that it can adapt to pipe fittings of different diameters and improve versatility. In addition, by moving the second slider 3, the position of the second guide wheel 31 is changed, the diameter of the guided coil is changed, and by changing the spacing between the second guide wheel 31 and the support 1, the pitch of the coil is changed.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
