[0034] Embodiment two: refer to Figures 1-11 The inner wall of the other end of the conveying pipe 1 is rotationally connected with a diversion pipe 7, the diversion pipe 7 is provided with a threaded strip 8, and the side wall of the diversion pipe 7 is connected with a driving mechanism.

[0035] The principle and beneficial effects of the above scheme are:

[0036] After the end of the steel wire hose moves into the conveying pipe 1, the driving mechanism is started, the output end of the driving mechanism drives the diversion pipe 7 and the threaded strip 8 to rotate, the threaded strip 8 in rotation can contact the helical steel wire wrapped by the steel wire hose, thereby assisting to guide the movement of the steel wire hose, improving the stability of the movement of the steel wire hose, and ensuring the stability of the steel wire hose during the wrapping of the composite film material.

[0037] Embodiment three: refer to Figures 1-11 The driving mechanism comprises a gear ring 9, the diversion pipe 7 is sleeved with the gear ring 9 on the side wall outside the conveying pipe 1, the gear ring 9 is meshingly connected with one side of a gear 10, the gear 10 is connected with a rotating shaft 11, the rotating shaft 11 is rotationally connected with the conveying pipe 1, the end of the rotating shaft 11 is connected with the end of a spring 13, the other end of the spring 13 is connected with the end of a rotating shaft two 14, the rotating shaft two 14 is slidingly connected with the insertion hole, and the other end of the rotating shaft two 14 is connected with one side of an adjusting mechanism.

[0038] The principle and beneficial effects of the above scheme are:

[0039] The rotation of the steering pipe 7 is driven by the rotation of the gear ring 9, the rotation of the gear ring 9 is driven by the rotation of the gear 10 connected therewith, the rotation of the gear 10 is driven by the rotation of the rotating shaft 11, the rotating shaft 11 rotates while the spring 13 and the rotating shaft two 14 rotate, the rotation of the rotating shaft two 14 is driven by the end of the adjusting mechanism, which greatly reduces the complexity of the mechanism inside; since the gear ring 9 is arranged on the side wall outside the conveying pipe 1 where the steering pipe 7 is arranged, the lubrication difficulty between the gear ring 9 and the gear 10 can be reduced, and the external gear ring 9 and the gear 10 can improve the cooling effect in the mechanism, which can further provide more convenient maintenance and repair space for the user; the rotating shaft 11 and the rotating shaft two 14 are slidingly connected, and further, the spring 13 can provide a buffer and a reset spring force for the extension and retraction of the rotating shaft two 14 in the rotating shaft 11.

[0040] Embodiment four: Figures 1-11 The other end of the adjusting mechanism is connected with the end of the rotating shaft three 15, the other end side wall of the rotating shaft three 15 is slidingly connected with the jack two, the jack two is arranged in the end of the rotating shaft four 17, the other end of the rotating shaft three 15 is connected with the inner wall of the jack two through the spring two 16, the other end of the rotating shaft four 17 is connected with the output end of the motor 18, and the motor 18 is installed on the conveying pipe 1.

[0041] The principle and beneficial effects of the above scheme are:

[0042] The rotation of the other end of the adjusting mechanism is driven by the rotation of the rotating shaft three 15, the spring two 16 and the rotating shaft four 17, the rotation of the rotating shaft four 17 is driven by the rotation of the output end of the motor 18, the rotating shaft three 15 is slidingly connected in the rotating shaft four 17, and further, the spring two 16 can provide a buffer and a reset spring force for the extension and retraction of the rotating shaft three 15 in the rotating shaft four 17.

[0043] Embodiment five: Figures 1-11 The other side of the gear 10 is connected with the gear two 20, the gear two 20 is connected with the rotating shaft five, the rotating shaft five is rotatably connected with the conveying pipe 1, the end of the rotating shaft five is connected with the output shaft of the liquid pump 19, and the liquid pump 19 is connected with the flow guide pipe 4.

[0044] The principle and beneficial effects of the above scheme are:

[0045] The gear 10 rotates while driving the gear two 20 connected with it to rotate, the gear two 20 drives the rotating shaft five to rotate, the rotating shaft five drives the output shaft of the liquid pump 19 to rotate, thereby providing power for the movement of the composite film material in the flow guide pipe 4, avoiding the influence of the length of the pipeline on the output material of the screw extruder, and the reduction of the temperature of the composite film material causing the flow guide pipe 4 to be partially blocked by the material, resulting in a reduction of the material input into the die pipe 2 from the flow guide pipe two 5, avoiding the thinning of the coating film on the steel wire hose, further ensuring the yield of the coating; at the same time, the blockage of the flow guide pipe 4 can be avoided, greatly reducing the number of maintenance and repair of the flow guide pipe 4.

[0046] Embodiment six: refer to Figures 1-11 The coil mechanism 3 comprises a receiving roller 21, a vertical plate 22, a rotating shaft six 24, a pressure mechanism 25 and a driving assembly 23, two vertical plates 22 are slidably connected to the workbench, the bottom end of the pressure mechanism 25 is arranged in the mounting groove of the vertical plate 22, the top end of the pressure mechanism 25 is connected with the bottom of one end of the rotating shaft six 24, the rotating shaft six 24 is arranged in the mounting groove, the receiving roller 21 is rotatably connected to the rotating shaft six 24, the receiving roller 21 is arranged between the two vertical plates 22, one vertical plate 22 is connected with the output end of the driving assembly 23, and the driving assembly 23 is mounted on the workbench.

[0047] The principle and beneficial effects of the above scheme are:

[0048] The receiving roller 21 is used for receiving the steel wire hose, when the device starts to work, the driving assembly 23 drives one vertical plate 22 to move left and right on the workbench, the rotation of the rotating pipe 7 drives the steel wire hose to move, and then the receiving roller 21 rotates on the rotating shaft six 24, the pressure mechanism 25 can buffer the vibration of the receiving roller 21 after the receiving roller 21 is subjected to tension, so as to improve the stability of the device, the left and right moving vertical plate 22 drives the receiving roller 21 to move while always keeping the steel wire hose to be transported in a coaxial state with the die pipe 2, preventing the left and right movement of the steel wire hose in the length direction, improving the stability of the hose transportation while preventing the vibration of the die pipe 2, further keeping the stability during coating and improving the uniformity of the coating.

[0049] Embodiment seven: refer to Figures 1-11 The pressure mechanism 25 comprises a mounting pipe 26, a piston 27 is slidably connected in the mounting pipe 26, a plug rod 28 is connected to the top of the piston 27, the plug rod 28 is slidably sealed with the circular hole at the top of the mounting pipe 26, the bottom of the piston 27 and the bottom of the mounting pipe 26 form a pressure cavity, and the bottom wall of the pressure cavity is connected with the bottom of the piston 27 through the spring three 29.

[0050] The principle and beneficial effects of the above scheme are:

[0051] When the receiving roller 21 on the rotating shaft six 24 starts to rotate, the receiving roller 21 is subjected to vibration in the up-down direction, the rotating shaft six 24 moves up and down, driving the inserting rod 28 and the piston 27 to move up and down, and further driving the spring three 29 to be stretched or compressed. The spring three 29 is arranged to increase the buffering effect of the mechanism, thereby avoiding vibration of the mechanism when the steel wire hose is output. After a period of work, the receiving roller 21 starts to rotate stably. Further, after the length of the steel wire hose wound on the receiving roller 21 becomes shorter, the weight applied to the receiving roller 21 decreases, the length of the spring three 29 becomes longer, and the height of the receiving roller 21 increases. Therefore, a downward arc appears on the steel wire hose in the conveying process, further preventing the bottom of the steel wire hose from being stuck at the entrance of the turning pipe 7.

[0052] Embodiment eight: Figures 1-11 The end of the hose 30 is connected to the inner wall of the pressure cavity, the installation cavity is filled with hydraulic oil, the other end of the hose 30 is connected to the side of the installation pipe two 31 in the adjusting mechanism, the bottom of the installation pipe two 31 is connected to the top of the conveying pipe 1, the piston two 32 is slidingly sealed in the installation pipe two 31, the bottom of the piston two 32 is connected to the bottom wall of the installation pipe two 31 through the spring four 33, the top of the piston two 32 and the inner top wall of the installation pipe two 31 form a pressure cavity two, the pressure cavity two is filled with hydraulic oil, and the other end of the hose 30 is arranged in the pressure cavity two.

[0053] The principles and beneficial effects of the above scheme are:

[0054] When the piston 27 moves up and down, the hydraulic oil in the pressure cavity enters or is discharged from the pressure cavity two through the hose 30, thereby driving the piston two 32 in the installation pipe two 31 to descend or ascend, and the length of the spring four 33 decreases or increases. The injection of hydraulic oil into the pressure cavity can further increase the buffering effect and provide oil seal protection for the spring three 29, thereby preventing oxidation and prolonging the service life of the spring three 29. When the piston 27 is subjected to excessive downward pressure or the device works in a high-temperature environment, the installation pipe 26 absorbs heat, causing the volume of the hydraulic oil in the installation pipe 26 to be too large. The hydraulic oil in the installation pipe 26 can be discharged through the hose 30 and injected into the pressure cavity two, thereby preventing the pressure cavity from bursting due to excessive pressure.

[0055] Embodiment nine: Figures 1-11 The bottom of the fixed shaft 34 is connected to the top of the piston two 32, the fixed shaft 34 is slidingly sealed with the second circular hole in the top of the installation pipe two 31, the top of the fixed shaft 34 is rotatably connected to the conical wheel 35, the diameter of the top of the conical wheel 35 is smaller than the diameter of the bottom of the conical wheel 35, one side of the conical wheel 35 is rotatably connected to the side of the guide wheel 36, the guide wheel 36 is connected to the other end of the rotating shaft two 14, the other side of the conical wheel 35 is rotatably connected to the side of the guide wheel two 37, and the guide wheel two 37 is connected to the other end of the rotating shaft three 15.

[0056] The principles and beneficial effects of the above scheme are:

[0057] The hydraulic oil entering or discharging from the pressure chamber two can make the piston two 32 descend or ascend, and the piston two 32 drives the fixed shaft 34 and the conical wheel 35 to descend or ascend. Since the diameter of the top of the conical wheel 35 is smaller than the diameter of the bottom of the conical wheel 35, when the receiving roller 21 just starts to rotate, the temperature of the composite film material output from the screw extruder into the die pipe 2 rises uniformly from low to high, and at this time, the gravity borne by the receiving roller 21 is large, and the volume of the hydraulic oil input into the pressure chamber two is large, so the flowability of the material output from the flow guide pipe two 5 onto the steel wire hose is relatively low. After the conical wheel 35 descends, the rotating speed of the guide wheel 36 and the guide wheel two 37 in frictional engagement with the two sides of the conical wheel 35 is reduced, and the spring 13 is elongated synchronously. The guide wheel 36 drives the rotating shaft two 14 to move rightward in the insertion hole of the rotating shaft 11, and the spring two 16 is elongated. The guide wheel two 37 drives the rotating shaft three 15 to move leftward in the insertion hole two of the rotating shaft four 17. The conical wheel 35 moving downward will reduce the rotating speed of the rotating shaft 11 output from the output end of the motor 18, and then reduce the rotating speed of the gear ring 9 driven by the gear 10, and then reduce the rotating speed of the threaded strip 8, and finally reduce the conveying speed of the conveying steel wire hose. At the same time, the lower rotating speed of the threaded strip 8 can prevent the phenomenon of slipping between the steel wire hose and the threaded strip 8 when the device just starts to work. When the receiving roller 21 rotates for a certain period of time, the temperature of the composite film material output from the screw extruder into the die pipe 2 rises greatly, and at this time, the gravity borne by the receiving roller 21 becomes small, and the volume of the hydraulic oil input into the pressure chamber two is reduced, so the flowability of the material output from the flow guide pipe two 5 onto the steel wire hose is relatively high. After the conical wheel 35 ascends, the rotating speed of the guide wheel 36 and the guide wheel two 37 in frictional engagement with the two sides of the conical wheel 35 is increased, and the spring 13 is shortened synchronously. The guide wheel 36 drives the rotating shaft two 14 to move leftward in the insertion hole of the rotating shaft 11, and the spring two 16 is shortened. The guide wheel two 37 drives the rotating shaft three 15 to move rightward in the insertion hole two of the rotating shaft four 17. The conical wheel 35 moving upward will increase the rotating speed of the rotating shaft 11 output from the output end of the motor 18, and then increase the rotating speed of the gear ring 9 driven by the gear 10, and then increase the rotating speed of the threaded strip 8, and finally increase the conveying speed of the conveying steel wire hose. After the rotating speed of the threaded strip 8 is increased, the phenomenon of uneven coating film on the steel wire hose can be prevented. The increase of the rotating speed of the gear 10 can increase the rotating speed of the liquid pump 19, so as to increase the flow speed of the material in the flow guide pipe 4. The reduction of the rotating speed of the gear 10 can reduce the rotating speed of the liquid pump 19, so as to reduce the flow speed of the material in the flow guide pipe 4. The increase and reduction of the flow speed of the material are synchronous with the moving speed of the steel wire hose in the die pipe 2, so as to prevent the steel wire hose from appearing protrusions or omissions when the coating film is formed, and improve the rationality of the mechanism when working.

[0058] Example ten: reference Figures 1-11The inner wall of the die pipe 2 is provided with an annular cooling groove 38, the end of a spiral cooling pipe 39 is connected to the inner wall of the annular cooling groove 38, the spiral cooling pipe 39 is in sliding connection with the side wall of the die pipe 2, and the other end of the spiral cooling pipe 39 is connected to the output end of the fan.

[0059] The principle and beneficial effects of the above scheme are:

[0060] When the film is coated, the temperature in the die pipe 2 will rise, so as to prevent the material from flowing and prevent the temperature of the die pipe 2 from being too high to cause plastic deformation of the steel wire hose. Therefore, the fan can be started to supply air to the spiral cooling pipe 39, the air in the spiral cooling pipe 39 can be blown to the coated steel wire hose through the annular cooling groove 38, and the mechanism can also guide the coated steel wire hose in the circumferential direction through air supply, so as to prevent the coated steel wire hose from contacting the inner wall of the die pipe 2 immediately after coating, avoid damage to the part just completed coating, and accelerate the cooling of the coating to speed up the molding. On the basis of guiding the steel wire hose in the circumferential direction, the steel wire hose can also be guided in the axial direction to improve the moving efficiency of the steel wire hose in the mechanism. The cold air output by the annular cooling groove 38 can cool the output composite film material, and the composite film material is deformed by the pressure applied while the steel wire hose moves, so as to more quickly and uniformly coat the steel wire hose.

[0061] Embodiment eleven: Figures 1-11 The other end of the spiral cooling pipe 39 is in contact with the side of a guide ring 40, the inner wall of the guide ring 40 is in sliding connection with the side wall of the die pipe 2, the other side of the guide ring 40 is connected to the end of a connecting rod 41, the other end of the connecting rod 41 is connected to one side of a guide ring two 42, the other side of the guide ring two 42 is connected to the guide pipe two 5 through a spring five 43, the spring five 43 is a hollow spring, and a plug rod 44 is connected to the guide pipe two 5 and is in sliding connection with the guide ring two 42.

[0062] The principle and beneficial effects of the above scheme are:

[0063] When the temperature of the material in the guide pipe two 5 is high, the spring five 43 with a hollow structure expands in volume and drives the guide ring two 42 to move to the right, further driving the connecting rod 41 and the guide ring 40 to move, and then compressing the spiral cooling pipe 39 to quickly cool the part of the steel wire hose just coated. When the temperature of the material in the guide pipe two 5 is low, the spring five 43 with a hollow structure shrinks in volume and drives the guide ring two 42 to move to the left, further driving the connecting rod 41 and the guide ring 40 to move, and then resetting the spiral cooling pipe 39 to reduce the speed of cooling the part of the steel wire hose just coated, thereby improving the self-adjusting ability of the device.

[0065] The principle and beneficial effects of the above scheme are:

[0066] When the vertical plate 22 needs to move left and right, the driving motor 45 is started, the output end of the driving motor 45 drives the guide roller 46 to rotate, the annular sliding groove 49 with a plurality of angles is formed in the guide roller 46, therefore the annular sliding groove 49 can drive the sliding block 47 connected therewith to move left and right, and then the driving rod 48 drives the vertical plate 22 to move left and right, the annular sliding groove 49 with a plurality of angles is formed in the guide roller 46, and the annular sliding groove 49 is slidably connected with the sliding block 47, so that the parts in the mechanism can move left and right, the space in the mechanism is greatly saved, and the working efficiency of the mechanism is improved.

[0067] Embodiment thirteen: Figures 1-11 The end of the flow guide pipe 4 is connected with the end of a discharge pipe 50, the discharge pipe 50 is arranged above the liquid pump 19, and a one-way valve is arranged in the discharge pipe 50.

[0068] The principle and beneficial effects of the above scheme are:

[0069] After the delivery of the composite film material in the flow guide pipe 4 is completed, the output end of the motor 18 reversely rotates, finally drives the gear two 20 to rotate and reversely drives the rotating shaft five, at the same time, the liquid pump 19 reversely moves, and the output end of the screw extruder is closed, and then the excess material in the flow guide pipe 4 is discharged through the one-way valve and the discharge pipe 50, so that the cooled material is prevented from causing blockage in the structure; at the same time, the one-way valve can prevent the impurities outside the device from entering the die pipe 2.
