DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] Example 1: Reference Figure 1-Figure 11 The co-extrusion composite extrusion die head for the production of steel wire hose includes: a delivery pipe 1, a die head tube 2, a coil mechanism 3, a guide pipe 4, a guide pipe 5 and an annular guide groove 6. The end of the delivery pipe 1 is connected to the end of the die head tube 2, and the other end of the delivery pipe 1 faces the coil mechanism 3. The coil mechanism 3 and the die head tube 2 are both installed on a workbench. An annular guide groove 6 is opened on the inner wall of the die head tube 2. The inner wall of the annular guide groove 6 is connected to the ends of multiple guide pipes 5. The other end of the guide pipe 5 is connected to the screw extruder through the guide pipe 4.

[0032] The principles and beneficial effects of the above scheme are:

[0033] The steel wire hose is wound on the coil mechanism 3. When the steel wire hose is started to be coated with a composite film, the end of the steel wire hose is inserted into the conveying pipe 1. After the steel wire hose moves into the die head tube 2, the screw extruder is started to convey the composite film material through the guide pipe 4 to the guide pipe 2 5, and then conveyed to the annular guide groove 6 through the guide pipe 2 5. Subsequently, the composite film material is coated on the steel wire hose. By setting up multiple guide pipes 2 5 to convey the composite film material to the annular guide groove 6, the uniformity of the material conveyed to the side wall of the steel wire hose is improved, ensuring that the end of the composite film on the processed steel wire hose is The part will not tilt after coating, which can improve the coating quality of the composite film material for the steel wire hose and ensure that the cracks in the steel wire hose under high temperature environment can be completely coated by the composite film; the setting of the annular guide groove 6 further improves the flow effect and coating effect of the composite film material, and can prevent the material from prematurely adhering to the side wall of the steel wire hose to form a bulge, prevent the mechanical properties of the steel wire hose from changing after processing, and avoid uneven heating of the steel wire hose due to the irregular external shape, thereby further extending the service life of the steel wire hose.

[0034] Example 2: Reference Figure 1-Figure 11 The inner wall of the other end of the delivery pipe 1 is rotatably connected with a steering pipe 7, on which a threaded strip 8 is provided, and the side wall of the steering pipe 7 is connected with a driving mechanism.

[0035] The principles 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, and the output end of the driving mechanism drives the steering tube 7 and the threaded strip 8 to rotate. The rotating threaded strip 8 can contact the spiral steel wire covered by the steel wire hose, and then can assist in guiding the steel wire hose to move, thereby improving the stability of the steel wire hose movement and ensuring its stability during the composite film material coating.

[0037] Example 3: Reference Figure 1-Figure 11 The driving mechanism includes: a gear ring 9, the steering tube 7 is placed on the side wall outside the conveying tube 1 and is equipped with a gear ring 9, the gear ring 9 is meshed and connected with one side of a gear 10, the gear 10 is connected with a rotating shaft 11, the rotating shaft 11 is rotatably connected with the conveying tube 1, the inner wall of the socket at 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 the rotating shaft 14, the rotating shaft 14 is slidably connected with the socket, and the other end of the rotating shaft 14 is connected with one side of the adjustment mechanism.

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

[0039] The rotation of the steering tube 7 is driven by the rotation of the gear ring 9, and the rotation of the gear ring 9 is driven by the rotation of the gear 10 meshing therewith, and the rotation of the gear 10 is driven by the rotation of the rotating shaft 11. When the rotating shaft 11 rotates, the spring 13 and the second rotating shaft 14 rotate, and the rotation of the second rotating shaft 14 is driven by the end of the adjustment mechanism, which greatly reduces the complexity of the internal mechanism; since the gear ring 9 is arranged on the side wall of the steering tube 7 outside the conveying pipe 1, the difficulty of lubrication between the gear ring 9 and the gear 10 can be reduced. At the same time, the external gear ring 9 and the gear 10 can improve the cooling effect in the mechanism, and further provide users with more convenient maintenance and repair space; the rotating shaft 11 is slidably connected with the second rotating shaft 14, and it can be further known that the spring 13 can provide buffering and reset elastic force for the expansion and contraction of the second rotating shaft 14 in the rotating shaft 11.

[0040] Example 4: Reference Figure 1-Figure 11 The other side of the adjustment mechanism is connected to the end of the rotating shaft three 15, the side wall of the other end of the rotating shaft three 15 is slidably connected to the second socket, the second socket is opened at the end of the rotating shaft four 17, the other end of the rotating shaft three 15 is connected to the inner wall of the second socket through the spring two 16, the other end of the rotating shaft four 17 is connected to the output end of the motor 18, and the motor 18 is installed on the conveying pipe 1.

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

[0042] The rotation of the other end of the adjustment 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 slidably connected in the rotating shaft four 17. It can be further known that the spring two 16 can provide buffering and resetting elastic force for the extension and contraction of the rotating shaft three 15 in the rotating shaft four 17.

[0043] Example 5: Reference Figure 1-Figure 11 The other side of the gear 10 is meshed with the gear 2 20 , the gear 2 20 is connected to the rotating shaft 5 , the rotating shaft 5 is rotatably connected to the delivery pipe 1 , the end of the rotating shaft 5 is connected to the output shaft of the liquid pump 19 , and the liquid pump 19 is connected to the guide pipe 4 .

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

[0045] When the gear 10 rotates, it drives the gear 2 20 meshing with it to rotate. The rotation of the gear 2 20 drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the output shaft of the liquid pump 19 to rotate, thereby providing power for the movement of the composite film material in the guide tube 4, avoiding the influence of the pipeline length during the process of the screw extruder outputting the material. Due to the decrease in the temperature of the composite film material, the guide tube 4 is partially blocked by the material, resulting in a reduction in the material input from the guide tube 2 5 to the die head tube 2, avoiding the thinning of the coating film on the steel wire hose, and further ensuring the yield rate of the coating; at the same time, the blockage of the guide tube 4 can be avoided, greatly reducing the maintenance and overhaul times of the guide tube 4.

[0046] Example 6: Reference Figure 1-Figure 11 The coil mechanism 3 includes: a storage roller 21, a vertical plate 22, a rotating shaft 6 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 installed in the mounting groove of the vertical plate 22. The top of the pressure mechanism 25 is connected to the bottom of one end of the rotating shaft 6 24. The rotating shaft 6 24 is placed in the mounting groove. The storage roller 21 is rotatably connected to the rotating shaft 6 24. The storage roller 21 is placed between the two vertical plates 22. One vertical plate 22 is connected to the output end of the driving assembly 23. The driving assembly 23 is installed on the workbench.

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

[0048] The receiving roller 21 is used to receive the steel wire hose. When the device starts working, the driving assembly 23 drives a vertical plate 22 to move left and right on the workbench. After the rotation of the steering tube 7 drives the steel wire hose to move, the receiving roller 21 rotates on the rotating shaft 6 24. After the receiving roller 21 is subjected to tension, the pressure mechanism 25 can buffer the vibration of the receiving roller 21, thereby improving the stability of the device. While the vertical plate 22 moving left and right drives the receiving roller 21 to move, the steel wire hose can always be conveyed in a coaxial state with the die head tube 2, thereby preventing the steel wire hose from moving left and right in the length direction. While improving the conveying stability of the hose, it can prevent it from vibrating the die head tube 2, thereby further maintaining the stability during coating and improving the uniformity of coating.

[0049] Example 7: Reference Figure 1-Figure 11 The pressure mechanism 25 includes: a mounting tube 26, a piston 27 is slidably connected inside the mounting tube 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 tube 26, the bottom of the piston 27 and the bottom of the mounting tube 26 form a pressure chamber, and the bottom wall of the pressure chamber is connected to the bottom of the piston 27 through a spring three 29.

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

[0051] When the receiving roller 21 on the rotating shaft 6 24 starts to rotate, the receiving roller 21 is subjected to the vibration in the up and down directions. The up and down movement of the rotating shaft 6 24 drives the insertion rod 28 and the piston 27 to move up and down, thereby stretching or compressing the spring three 29. The setting of the spring three 29 can increase the buffering effect of the mechanism, thereby avoiding the mechanism from vibrating when outputting the steel wire hose. After a period of work, the receiving roller 21 starts to rotate stably. After the length of the steel wire hose wound on the receiving roller 21 is further shortened, the weight applied to the receiving roller 21 is reduced, the length of the spring three 29 is lengthened, and the height of the receiving roller 21 is increased. Therefore, a downward arc appears on the steel wire hose being transported, further preventing the bottom of the steel wire hose from being stuck at the entrance of the steering tube 7.

[0052] Example 8: Reference Figure 1-Figure 11 The inner wall of the pressure chamber is connected to the end of a hose 30, and hydraulic oil is filled in the mounting chamber. The other end of the hose 30 is connected to the side of the mounting tube 2 31 in the adjustment mechanism, and the bottom of the mounting tube 2 31 is connected to the top of the delivery pipe 1. A piston 2 32 is slidably sealed in the mounting tube 2 31, and the bottom of the piston 2 32 is connected to the bottom wall of the mounting tube 2 31 through a spring 4 33. A pressure chamber 2 is formed between the top of the piston 2 32 and the top wall of the mounting tube 2 31, and hydraulic oil is filled in the pressure chamber 2. The other end of the hose 30 is arranged in the pressure chamber 2.

[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 chamber enters or is discharged from the pressure chamber 2 through the hose 30, thereby causing the piston 2 32 in the mounting tube 2 31 to descend or rise, and the length of the spring 4 33 to decrease or increase. Injecting hydraulic oil into the pressure chamber can further increase the buffering effect, and perform oil seal protection on the spring 3 29 to prevent it from being oxidized and increase its service life. When the piston 27 is subjected to excessive downward pressure or the device is working in a high temperature environment and the mounting tube 26 absorbs heat, causing the volume of the hydraulic oil therein to be too large, the hydraulic oil in the mounting tube 26 can be discharged through the hose 30 and injected into the pressure chamber 2 to prevent the pressure chamber from being overloaded and bursting.

[0055] Example 9: Reference Figure 1-Figure 11 The top of the second piston 32 is connected to the bottom of the fixed shaft 34, and the fixed shaft 34 is slidably sealed with the second circular hole on the top of the second mounting tube 31. The top of the fixed shaft 34 is rotatably connected to a conical wheel 35, and the diameter of the top of the conical wheel 35 is smaller than the diameter of its bottom. One side of the conical wheel 35 is rotatably matched with the side of the guide wheel 36, and the guide wheel 36 is connected to the other end of the rotating shaft 14. The other side of the conical wheel 35 is rotatably matched with the side of the second guide wheel 37, and the guide wheel 2 37 is connected to the other end of the rotating shaft 15.

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

[0057] The hydraulic oil entering or discharging the second pressure chamber from the hose 30 can make the second piston 32 descend or ascend, and the second piston 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 thereof, when the take-up roller 21 just starts to rotate, the temperature of the composite film material outputted from the screw extruder to the die head tube 2 rises uniformly from low to high. At this time, the gravity borne by the take-up roller 21 is large, and the volume of the hydraulic oil inputted into the second pressure chamber is large. Therefore, the fluidity of the material outputted from the guide tube 25 to the steel wire hose is relatively low. After the conical wheel 35 descends, the rotation speeds of the guide wheels 36 and the second guide wheels 37 which are frictionally matched with the two sides of the conical wheel 35 decrease. The spring 13 of the first step is extended, and the guide wheel 36 drives the second shaft 14 to move rightward in the socket of the shaft 11. The spring 16 is extended, and the guide wheel 37 drives the third shaft 15 to move leftward in the socket 2 of the fourth shaft 17. The tapered wheel 35 moving downward will reduce the speed of the output of the motor 18 to the shaft 11, thereby reducing the rotation speed of the gear ring 9 driven by the gear 10, and then reducing the speed of the thread strip 8, and finally reducing the conveying speed of the conveying wire hose. At the same time, when the device starts to work, the lower speed of the thread strip 8 can prevent the wire hose and the thread strip 8 from slipping. When the take-up roller 21 rotates for a certain period of time, the composite film output by the screw extruder to the die head tube 2 The material causes the temperature of the die head tube 2 to rise significantly, and at this time the gravity borne by the storage roller 21 becomes smaller, and the volume of the hydraulic oil input into the pressure chamber 2 is reduced. Therefore, the fluidity of the material output from the guide tube 2 5 to the steel wire hose is relatively high. After the conical wheel 35 rises, the speed of the guide wheel 36 and the guide wheel 2 37 that are frictionally matched with the two sides of the conical wheel 35 increases, the synchronous spring 13 shortens, and the guide wheel 36 drives the rotating shaft 2 14 to move to the left in the socket of the rotating shaft 11. The spring 2 16 shortens, and the guide wheel 2 37 drives the rotating shaft 3 15 to move to the right in the socket 2 of the rotating shaft 4 17. The upward moving conical wheel 35 will increase the speed of the output end of the motor 18 to the rotating shaft 11, and then The gear 10 drives the gear ring 9 to rotate faster, and then the rotation speed of the threaded strip 8 is accelerated, and finally the conveying speed of the conveying steel wire hose is accelerated. After the rotation speed of the threaded strip 8 is accelerated, the uneven coating on the steel wire hose can be prevented; the increase in the rotation speed of the gear 10 can drive the rotation speed of the liquid pump 19 to increase, so the flow speed of the material in the guide tube 4 can be accelerated, and the reduction in the rotation speed of the gear 10 can drive the rotation speed of the liquid pump 19 to decrease, so the flow speed of the material in the guide tube 4 can be slowed down. The acceleration and deceleration of the material flow speed are synchronized with the moving speed of the steel wire hose in the die head tube 2, which can prevent the steel wire hose from bulging or missing during coating, thereby improving the rationality of the mechanism during operation.

[0058] Example 10: Reference Figure 1-Figure 11The inner wall of the die head tube 2 is provided with an annular cooling groove 38, the inner wall of the annular cooling groove 38 is connected to the end of a spiral cooling tube 39, the spiral cooling tube 39 is slidingly connected to the side wall of the die head tube 2, and the other end of the spiral cooling tube 39 is connected to the output end of the fan.

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

[0060] When laminating, the temperature inside the die head tube 2 will increase. Therefore, in order to prevent the fluidity of the material from being enhanced and to prevent the temperature of the die head tube 2 from being too high and causing plastic deformation of the steel wire hose, the fan can be started to supply air to the spiral cooling tube 39. The wind in the spiral cooling tube 39 can be blown to the steel wire hose after lamination through the annular cooling groove 38. At the same time, the mechanism can also guide the steel wire hose after lamination circumferentially through the air supply to prevent it from contacting the inner wall of the die head tube 2 immediately after lamination, avoiding damage to the part that has just been laminar. The lamination can also be cooled to accelerate molding. On the basis of circumferentially guiding the steel wire hose, it can also be auxiliary axially guided to improve the movement 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 while the steel wire hose is moving, pressure is applied to the composite film material to cause the output composite film material to deform, so as to facilitate faster and more uniform coating of the steel wire hose.

[0061] Example 11: Reference Figure 1-Figure 11 The other end of the spiral cooling tube 39 contacts and cooperates with the side of the guide ring 40, the inner wall of the guide ring 40 is slidably connected to the side wall of the die head tube 2, the other side of the guide ring 40 is connected to the end of the connecting rod 41, the other end of the connecting rod 41 is connected to one side of the guide ring 2 42, and the other side of the guide ring 2 42 is connected to the guide tube 2 5 through the spring 5 43, the spring 5 43 is specifically a hollow spring, and the guide tube 2 5 is connected with an insertion rod 44, and the insertion rod 44 is slidably connected to the guide ring 2 42.

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

[0063] When the temperature of the material in the guide tube 25 is high, the volume of the spring 5 43 with a hollow structure expands and drives the guide ring 2 42 to move to the right, further drives the connecting rod 41 and the guide ring 40 to move, and then compresses the spiral cooling tube 39, which can quickly cool down the part of the steel wire hose that has just been coated; when the temperature of the material in the guide tube 25 is low, the volume of the spring 5 43 with a hollow structure shrinks and drives the guide ring 2 42 to move to the left, further drives the connecting rod 41 and the guide ring 40 to move, and then the spiral cooling tube 39 is reset, reducing the speed of cooling the part of the steel wire hose that has just been coated, thereby improving the device's ability to adjust itself.

[0064] Example 12: Reference Figure 1-Figure 11The driving assembly 23 includes: a driving motor 45, a driving motor 45 is connected to the workbench, a guide roller 46 is connected to the output end of the driving motor 45, an annular slide groove 49 is opened on the guide roller 46, a plurality of folded corners are arranged on the annular slide groove 49, and two adjacent folded corners are arranged opposite to each other. The bottom of the slider 47 is slidably connected in the annular slide groove 49, and the top of the slider 47 is connected to the end of the driving rod 48, and the other end of the driving rod 48 is connected to a vertical plate 22.

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

[0066] When it is necessary to move the vertical plate 22 left or right, start the drive motor 45, and the output end of the drive motor 45 drives the guide roller 46 to rotate. The guide roller 46 is provided with an annular slide groove 49 with multiple angles, so that the annular slide groove 49 can drive the slider 47 slidably connected thereto to move left or right, and then drive the vertical plate 22 to move left or right through the drive rod 48. An annular slide groove 49 with multiple angles is provided on the guide roller 46, and the annular slide groove 49 is slidably connected to the slider 47. While realizing the left and right movement of the parts in the mechanism, it greatly saves the space in the mechanism and improves the working efficiency of the mechanism when it is working.

[0067] Example 13: Reference Figure 1-Figure 11 The side of the flow guide pipe 4 is connected to the end of a discharge pipe 50 . The discharge pipe 50 is arranged above the liquid pump 19 . A one-way valve is provided in the discharge pipe 50 .

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

[0069] After the conveying of the composite film material in the guide tube 4 is completed, the output end of the motor 18 rotates in the opposite direction, and finally drives the gear 20 to rotate and drive the rotating shaft 5 to reverse. At the same time, the liquid pump 19 moves in the opposite direction, and at the same time, the output end of the screw extruder is closed, and then the excess material in the guide tube 4 is discharged from the discharge pipe 50 through the one-way valve to avoid blockage of the cooled material in the structure; at the same time, the setting of the one-way valve can prevent external impurities from entering the die head tube 2 when the device is working.
