[0029] The winding mechanism comprises a first winding reel 1 and a second winding reel 2, the first winding reel 1 and the second winding reel 2 are coaxially arranged, a side of the second winding reel 2 close to the first winding reel 1 is fixedly connected with a plurality of fixing rods 3 at equal intervals in the circumferential direction, a plurality of positioning holes 4 are opened on the first winding reel 1, and the fixing rods 3 are arranged corresponding to the positioning holes 4;

[0030] A transmission assembly, the transmission assembly is mounted on the frame 31, and the first winding disc 1 is fixedly connected to the transmission assembly;

[0031] A horizontal moving platform, the horizontal moving platform is mounted on the frame 31, and the second winding disc 2 is detachably connected to the moving platform;

[0032] A through hole is opened at the center position of the connecting tube 5 and the second winding drum 2, and the connecting tube 5 is coaxially inserted in the through hole. One end of the connecting tube 5 close to the second winding drum 2 is vertically connected to a vertical tube 6 for fixed connection. The top of the vertical tube 6 is arranged corresponding to the fixed rod 3 and is installed with a fixed connector, and the end of the connecting tube 5 away from the vertical tube 6 is installed with a rotating connector.

[0033] When the present invention is used, the output end of the ventilator is connected to the end of the connecting pipe 5 through a rotating connector, one end of the vertical pipe 6 is connected to the delivery pipe through a fixed connector, and it is fixed to the fixed rod 3, and the delivery pipeline is rolled up on multiple fixed rods 3 through the transmission component. The distance between the first winding disk 1 and the second winding disk 2 can be adjusted by setting a horizontal movable platform, so as to control the winding range. When winding, one end of the pipeline is fixed and the other end is wound and released. The connecting pipe 5 can be rotated by setting a rotating connector, so as to avoid bending of the pipeline during the winding process and affecting the normal air supply.

[0034] The present invention realizes the connection of the pipeline by cooperating with the vertical pipe 6 through the connecting pipe 5, thereby avoiding bending during the winding process of the pipeline and ensuring that the pipeline can supply gas smoothly during the winding process.

[0036] The driving motor controls the rotation of the driving sprocket, which drives the driven sprocket to rotate through the chain, so that the hollow shaft 19 can rotate. The rotation of the hollow shaft 19 drives the first winding drum 1 to rotate. The rotation of the first winding drum 1 drives the second winding drum 2 to rotate through the fixed rod 3, and the pipeline is wound on the fixed rod 3.

[0037] A further optimized solution is that the horizontal moving table includes a track 9 symmetrically fixedly connected to the frame 31, a slide 10 is slidably connected to the top of the track 9, a mounting plate 11 is fixedly connected to one side of the frame 31, a threaded shaft 12 is rotatably connected to the mounting plate 11, a slider 13 is threadedly connected to the threaded shaft 12, the slider 13 is fixedly connected to the bottom of the slide 10, and the slider 13 is slidably matched with the top surface of the frame 31, a crank 14 is installed at the end of the threaded shaft 12, a clamping assembly is installed on the top of the slide 10, and the second winding disk 2 is detachably connected to the clamping assembly.

[0039] A further optimized solution is that the clamping assembly includes a fixed plate 15 vertically fixedly connected to the top surface of the slide 10, a clamping cylinder 16 is fixedly connected to one side of the fixed plate 15, a clamping plate 17 is slidably connected to the top surface of the slide 10, one end of the clamping cylinder 16 is fixedly connected to the clamping plate 17, and clamping blocks 18 are fixedly connected to the sides of the clamping plate 17 and the fixed plate 15 that are close to each other, a hollow shaft 19 is fixedly connected to the center position of one side of the second winding disk 2, and a mounting gear 20 is rotatably connected to the hollow shaft 19, and the mounting gear 20 is arranged between the two clamping blocks 18, and the connecting pipe 5 is passed through the hollow shaft 19.

[0040] A clamping block is fixedly connected to the inner wall of the hollow shaft 19, and a clamping groove is provided on the outer wall of the connecting tube 5. The clamping block cooperates with the clamping groove, so that the connecting tube 5 and the hollow shaft 19 can only slide relative to each other but cannot rotate relative to each other.

[0041] The setting of the clamping assembly can be used to remove the second winding disk 2. The setting of the clamping cylinder 16 can push the clamping plate to slide on the top surface of the frame 31. One side of the clamping block 18 is set as an arc surface, and a tooth groove is set on the arc surface, which meshes with the installation gear 20.

[0042] A further optimized solution is that a positioning assembly is installed on the top surface of the slide 10, and the positioning assembly includes a positioning cylinder 21 fixedly connected to the top surface of the slide 10, a positioning block 22 is fixedly connected to one side of the second winding disk 2, a positioning groove is opened on the positioning block 22, and a positioning rod is fixedly connected to the output end of the positioning cylinder 21, and the positioning rod and the positioning groove are limitedly matched.

[0043] Further optimization scheme, a pipeline guide assembly is installed on the frame 31, and the pipeline guide assembly includes a mounting frame 23 fixedly connected to the frame 31, a mounting block 32 is slidably connected to the mounting frame 23, a guide hole 24 is opened on the mounting block 32, and the mounting block 32 is arranged between the first winding reel 1 and the second winding reel 2. A stepped hole is opened at the top of the guide hole 24, and a sliding shaft is slidably connected in the stepped hole. A compression spring is sleeved on the top of the sliding shaft, and a pressure pad is fixedly connected to one end of the compression spring. The pressure pad is slidably connected to the sliding shaft. The sliding shaft is threaded with an adjusting nut, and the adjusting nut abuts against the pressure pad. The elastic force of the compression spring is controlled by the adjusting nut. The other end of the compression spring is fixedly connected to the inner wall of the stepped hole, and the other end of the sliding shaft is fixedly connected to the arc plate. The positioning of the pipeline is realized by the setting of the arc plate, and a ball bearing is installed on the arc plate to facilitate stable transportation of the pipeline.

[0044] A further optimized solution is that a clamping assembly is installed on the frame 31, and the clamping assembly includes a support plate 25 fixedly connected to the frame 31, to which a first clamping cylinder 26 is rotatably connected, and a pressure plate 27 is rotatably connected to the support plate 25, and the pressure plate 27 is located above the first clamping cylinder 26, and one end of the first clamping cylinder 26 is rotatably connected to the middle of the pressure plate 27, and a second clamping cylinder 28 is rotatably connected to the frame 31, and one end of the second clamping cylinder 28 is rotatably connected to the middle of the first clamping cylinder 26. The clamping assembly and the pipeline guide assembly can be located on both sides of the frame 31. If the pipeline guide assembly and the clamping assembly are located on the same side of the frame 31, it is necessary to control the distance between the two to avoid movement interference. The angle of the first clamping cylinder 26 is controlled by the second clamping cylinder 28, and the first clamping cylinder 26 drives the pressure plate 27 to deflect at an angle. Then, the first clamping cylinder 26 drives the pressure plate 27 to deflect, thereby causing the pressure plate 27 to deflect at an angle. The pipeline is pressed onto the fixed rod 3 through the pressure plate 27 to ensure the tension of the pipeline.

[0045] Further optimization scheme, the support assembly is provided with several groups at the bottom of the frame 31, and the support assembly includes a threaded rod 29, and the threaded rod 29 is vertically threadedly connected to the bottom of the frame 31, and the bottom of the threaded rod 29 is rotatably connected with a universal wheel 30. By rotating and adjusting the extension length of the threaded rod 29, the support heights of multiple support assemblies can be adjusted to be different, ensuring that the device can always be in a relatively stable state. The setting of the universal wheel 30 can enable the device to move, and a brake assembly is installed on the universal wheel for fixing the device. In this embodiment, a positioning nut can be installed on the threaded rod 29, and the positioning nut abuts against the bottom of the frame 31, thereby ensuring the stability of the threaded rod 29 support.

[0046] Among them, foot-operated telescopic rods are respectively arranged on the four legs of the frame. The foot-operated telescopic rods adopt the existing technology. Through the setting of the foot-operated telescopic rods, the height of the device can be adjusted according to actual needs, thereby improving the practical range and flexibility of the device.
