[0031] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figure 1 As shown, this embodiment discloses an automatic coiling device, including a winding cylinder 1, a constriction drive assembly 2, a lower disc 3, and an upper disc 4. The winding cylinder 1 includes multiple arc-shaped cylindrical pieces 101 arranged in a ring array. A rope-threading guide channel 102 is provided between any two adjacent arc-shaped cylindrical pieces 101. The rope-threading guide channel 102 can be replaced by channel steel. The upper end of each arc-shaped cylindrical piece 101 is movably connected to the constriction drive assembly 2 in the middle. The lower end of each arc-shaped cylindrical piece 101 is hinged to the lower disc 3. The lower disc 3 has a lower rope-threading notch 301 at a position corresponding to the rope-threading guide channel 102.

[0033] The upper disc 4 is located above the winding cylinder 1. The top surface of the upper disc 4 is rotatably connected to the lifting assembly 5. The bottom surface of the upper disc 4 is connected to the winding cylinder 1 through the plug-in positioning assembly 6. The upper disc 4 has an upper rope threading notch 401 at a position corresponding to the rope threading guide channel 102. Each upper rope threading notch 401 is equipped with a rope threader 7.

[0034] like Figure 2 and 3As shown, in this embodiment, the constriction drive assembly 2 includes a guide cylinder 201, which is fixedly connected to the lower disc 3. A guide rod 202 is provided in the guide cylinder 201, and multiple connecting arms 203 are provided around the upper end of the guide rod 202. Each connecting arm 203 corresponds to each arc-shaped cylindrical piece 101, and one end of the connecting arm 203 is hinged to the connecting arm 203, and the other end is hinged to the arc-shaped cylindrical piece 101. The lower end of the guide rod 202 passes through the reserved hole on the lower disc 3 and is connected to the first cylinder 204 below. The extension and retraction of the first cylinder 204 drives the guide rod 202 to move up and down in the guide cylinder 201. During the up and down movement, the guide cylinder 201 also drives each arc-shaped cylindrical piece 101 to tilt towards or away from the central axis through the connecting arms 203.

[0035] During the winding process of the winding drum 1, the lower disc 3, guide cylinder 201, guide rod 202, and connecting arm 203 also rotate during the winding. To enable the normal extension and retraction drive function of the first cylinder 204, as follows... Figure 4 As shown, in this embodiment, the telescopic end of the first cylinder 204 is connected to the lower end of the guide rod 202 via a rotating structure. Specifically, the rotating structure includes a detachable lower connecting plate 205 on the telescopic end of the first cylinder 204, and a detachable upper connecting plate 206 on the lower end of the guide rod 202. Multiple L-shaped barbs 207 are welded around the lower connecting plate 205, and the L-shaped barbs 207 hook onto the upper connecting plate 206.

[0036] like Figure 5 and 6 As shown, in this embodiment, the lower disk 3 is poweredly connected to the rotary drive device 8. The rotary drive device 8 includes a reducer 801 and a drive motor 802. The reducer 801 is mounted on a motor mount, and the motor mount is mounted on a base frame. After the guide cylinder 201 is fixedly connected to the lower disk 3, its lower end passes through the reducer 801. The output end of the reducer 801 is in the form of a sleeve. After the output end of the reducer 801 is fitted onto the guide cylinder 201, it drives the guide cylinder 201 to rotate through a keyway connection.

[0037] like Figure 7 As shown, in this embodiment, the lifting assembly 5 includes a lifting seat 501, which is slidably connected to the support frame 503 via linear slide rail structures 502 on both sides. The bottom of the support frame 503 is connected to the base frame. A second cylinder 504 is provided on both sides of the lifting seat 501. The body of the second cylinder 504 is connected to the support frame 503, and the telescopic end of the second cylinder 504 is connected to the lifting seat 501.

[0038] In this embodiment, a winding guide device 10 is provided on the support frame 503. The winding guide device 10 conveys the rubber and plastic tube, making the winding cylinder 1 more neatly wound. Specifically, the winding guide device 10 includes a vertically arranged straight module 1001. A winding guide frame 1002 is provided on the movable part of the straight module 1001. The winding guide frame 1002 has a guide hole 1003, through which the rubber and plastic tube passes.

[0039] In this embodiment, grating sensors 11 are provided at both the upper and lower ends of the winding guide device 10 on the support frame 503. The working principle of the grating sensor 11 is as follows: when the rubber tube passes through the guide hole 1003, the grating sensor 11 detects the rubber tube and starts to delay. The rotary drive device 8 starts to work. Under the drive of the rotary drive device 8, the winding cylinder 1 rotates to complete the winding of the rubber tube. When the rubber tube on the winding cylinder 1 is wound to a certain length, the grating sensor 11 can no longer detect the rubber tube, the rotary drive device 8 stops working, and the packaging rope is conveyed downward along the rope guide channel 102 under the conveying of the rope threader 7. Then, the wound rubber tube is tied and packaged manually.

[0040] The bottom surface of the upper disc 4 is connected to one of the arc-shaped cylindrical plates 101 via a plug-in positioning assembly 6. In this embodiment, as shown... Figure 8 As shown, the insertion positioning component 6 includes a second positioning pin 601 and a second positioning sleeve 602 that are inserted and engaged. The second positioning pin 601 is fixed on the bottom surface of the upper disc 4, and the second positioning sleeve 602 is fixed on the arc-shaped cylindrical plate 101.

[0041] like Figure 9 and 10 As shown, in this embodiment, the rope threader 7 includes a roller seat 701, which is fixedly connected to the upper disc 4. Two rollers 702 are arranged side-by-side on the roller seat 701. Each roller 702 has a roller motor 703 at one end, which drives the roller 702 to rotate. Pressure rollers 704 are arranged side-by-side on the outer side of each roller 702. Connecting arms 705 are connected to both ends of each pressure roller 704. A spring frame 706 is provided on the roller seat 701, and the connecting arms 705 are slidably connected to the spring frame 706. A spring 707 is placed around the spring frame 706, and the four springs 707 apply pressure to the connecting arms 705 on both sides of the pressure roller 704. A rope-tying shaft 708 is provided on the roller seat 701, and the rope-tying shaft 709 releases the wound rope 709. To facilitate automatic cutting of the rope 709, pneumatic shears can also be installed on the roller seat 701.

[0042] After the lifting assembly 5 drives the upper disc 4 to rise, in order to prevent the upper disc 4 from rotating relative to the lifting seat 501, an anti-rotation assembly 9 is installed above the upper disc 4, such as... Figure 11As shown, the anti-rotation component 9 includes a first positioning sleeve 901 and a first positioning pin 902 that fit together. The first positioning sleeve 901 is fixed on the top surface of the upper disc 4. A guide sleeve 903 is sleeved on the outside of the first positioning pin 902. The guide sleeve 903 is fixedly connected to the lifting seat 501. A first connecting rod 904 and a second connecting rod 905 are arranged above the first positioning pin 902. The first connecting rod 904 and the second connecting rod 905 are respectively connected to the lifting seat 501 through a hinge seat 906. The proximal ends of the first connecting rod 904 and the second connecting rod 905 are hinged together. The non-hinged end of the first connecting rod 904 is connected to the first positioning pin 902 through a flexible rope 907. The non-intersecting end of the second connecting rod 905 abuts against a limiting block 908. The limiting block 908 is fixedly connected to the support frame 503.

[0043] The working principle of the lifting assembly 5 is as follows: when the lifting assembly 5 drives the upper disk 4 to rise, the limiting block 908 no longer blocks the second connecting rod 905, and the first positioning pin 902 slides down into the first positioning sleeve 901 under the action of gravity, thereby achieving the limiting and fixing of the upper disk 4. When the lifting assembly 5 drives the upper disk 4 to fall, the non-intersecting end of the second connecting rod 905 abuts against the limiting block 908. Through the lever structure formed by the first connecting rod 904 and the second connecting rod 905, the first connecting rod 904 pulls the first positioning pin 902 out of the first positioning sleeve 901 through the flexible rope 907, thereby releasing the limiting and fixing of the upper disk 4.

[0044] The working process of this invention is as follows: When the automatic coiling device is working, the rubber-plastic tube passes through the guide hole 1003 and is simultaneously placed into the winding cylinder 1 through the grating sensor 11. When the grating sensor 11 senses the rubber-plastic tube, a delay begins, and the rotary drive device 8 is driven by the power distribution system. Under the drive of the rotary drive device 8, the winding cylinder 1 rotates to complete the winding of the rubber-plastic tube. When the rubber-plastic tube on the winding cylinder 1 is wound to a certain length, and the grating sensor 11 no longer senses the rubber-plastic tube, the rotary drive device 8 stops rotating. The packaging rope is conveyed downward along the rope guide channel 102 by the rope threader 7, and then the wound rubber-plastic tube is tied and packaged manually. After the packaging work is completed, the lifting component 5 drives the upper disc 4 to rise. At this time, the insertion positioning component 6 releases the insertion positioning function, and then the narrowing drive component 2 drives each arc-shaped cylinder 101 to tilt towards the axis, so that the entire lower winding cylinder 1 presents an inverted cone structure, which facilitates the removal of the packaged rubber-plastic tube from the winding cylinder 1. After the packaged rubber and plastic tubes are removed from the winding drum 1, the lifting component 5 drives the upper disc 4 to descend, and the insertion positioning component 6 activates the insertion positioning function, so that the upper disc 4 rotates synchronously with the winding drum 1.

[0045] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
