Description

Technical Field

[0001] This utility model relates to the technical field of high-pressure hose production equipment, specifically to a stranding machine for constant-pressure stranding of high-pressure hoses. Background Technology

[0002] High-pressure hoses, as a key component combining high pressure resistance, corrosion resistance, and flexibility, are widely used in many important fields such as industry, agriculture, construction machinery, petrochemicals, and hydraulic transmission. In industrial production, they are the core connectors in hydraulic systems that transmit high-pressure oil, ensuring power transmission for machine tools, stamping equipment, and other equipment. In the construction machinery field, large equipment such as excavators and cranes rely on high-pressure hoses to achieve precise movements of hydraulic cylinders. In the petrochemical industry, high-pressure hoses are used to transport high-pressure fluids such as crude oil and chemical media. Irrigation equipment and large agricultural machinery in the agricultural field also rely on the high-pressure liquid transportation function of high-pressure hoses.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-3 As shown, it illustrates a high-pressure hose constant-pressure stranding machine according to an embodiment of the present invention, comprising: The main body 1 of the stranding machine and the curing mechanism 2 are arranged side by side. The curing mechanism 2 is used to accelerate the curing of the adhesive between the hose and the fiber. The circulating cooling mechanism 3 is located on the side of the curing mechanism 2 away from the main body 1 of the stranding machine. The circulating cooling mechanism 3 includes a cooling water tank 31 and a circulating pump 39. A cooling rack 33 is fixedly connected to the top of the cooling water tank 31. The drying mechanism 4 is located on the side of the circulating cooling mechanism 3 away from the curing mechanism 2. The drying mechanism 4 includes a drying box 41, and a traction mechanism 5 is installed inside the drying box 41.

[0025] The cooling rack 33 has a drainage hole 34 at the bottom. The cooling rack 33 has guide rollers 35 rotatably connected to both ends inside. The cooling rack 33 has a water distribution pipe 36 fixedly connected to the top of the rear baffle. Multiple sets of bamboo joint pipes 37 are fixedly installed at the upper end of the water distribution pipe 36. The nozzles 38 are fixedly connected to the ends of the bamboo joint pipes 37. The input end of the circulation pump 39 is fixedly connected to a water pumping pipe 310. The water pumping pipe 310 is fixedly connected to the bottom end of the cooling water tank 31 through one end of the circulation pump 39. The output end of the circulation pump 39 is fixedly connected to a water delivery pipe 311. The water delivery pipe 311 is fixedly connected to the input end of the water distribution pipe 36 through one end of the circulation pump 39. A water inlet 32 ​​is fixedly connected to the upper front side of the cooling water tank 31.

[0026] The curing mechanism 2 includes a curing frame 21. The top of the curing frame 21 is rotatably connected to a frame cover 22 via a hinge. Both ends of the frame cover 22 have semi-circular openings 23 at their bottom. Multiple sets of heating rods 26 are fixedly connected inside the frame cover 22 around the semi-circular openings 23.

[0027] The top two sides of the curing frame 21 are provided with semi-circular openings 24. The bottom of the semi-circular openings 24 are rotatably connected to guide rollers 25. Multiple sets of heating rods 26 are fixedly connected inside the curing frame 21 around the semi-circular openings 24.

[0028] In some examples, the cooling water is circulated by the circulating cooling mechanism 3. The circulating pump 39 draws out the cooling water from the cooling water tank 31 and sends it into the water distribution pipe 36 through the water delivery pipe 311. The water is then sprayed onto the surface of the hose through the nozzle 38. The guide rollers 35 are set at both ends inside the cooling rack 33 to support the hose and facilitate its movement. The drain hole 34 allows the sprayed cooling water to return to the cooling water tank 31. During production cooling, the water level inside the cooling rack 33 can be ensured to be close to the maximum water level in advance. At this time, the part of the hose between the two sets of guide rollers 35 will be submerged in cooling water, thereby avoiding the problem of excessive local cooling of the hose, reducing defects such as deformation and cracks caused by temperature stress, and ensuring the structural stability of the hose. The water inlet 32 ​​facilitates timely replenishment of cooling water. By setting up a curing mechanism 2, the curing of the curing agent on the surface of the hose is accelerated. Multiple sets of electric heating rods 26 surround the hose to heat it evenly from all directions, which accelerates the curing of the adhesive, improves production efficiency, and the full curing of the adhesive can enhance the bonding strength between the fiber and the hose, effectively preventing the fiber from falling off the hose surface during later use and extending the service life of the high-pressure hose.

[0029] For example, such as Figure 4 As shown, an exhaust port 42 is fixedly connected to the bottom front side of the drying box 41. Openings 43 are provided at both ends of the drying box 41. Guide rollers 44 are rotatably connected to the bottom of the openings 43. Sliding grooves 48 are symmetrically provided on the inner walls of the front and rear sides of the drying box 41.

[0030] A hot air blower 45 is fixedly connected to the top of the drying oven 41. A main air duct 46 is fixedly connected to the top of the interior of the drying oven 41. The main air duct 46 is connected to the air outlet of the hot air blower 45. Multiple sets of branch air ducts 47 are fixedly connected to the front and rear sides of the main air duct 46.

[0031] The traction mechanism 5 includes an electric push rod 51 and a traction motor 56. The output end of the electric push rod 51 is fixedly connected to a lifting frame 52. The two ends of the lifting frame 52 are fixedly connected to sliders 53. The sliders 53 are slidably installed inside the slide groove 48. The outer diameter of the sliders 53 matches the inner diameter of the slide groove 48. The lifting frame 52 is slidably connected to the drying box 41 through the sliders 53 and the slide groove 48. The lifting roller 54 is rotatably connected inside the lifting frame 52.

[0032] The traction motor 56 is fixedly installed on the front side of the drying box 41. The output shaft of the traction motor 56 is fixedly connected to the traction roller 55. The traction roller 55 is rotatably installed inside the drying box 41. The surfaces of the lifting roller 54 and the traction roller 55 are both provided with anti-slip textures. In some examples, a drying mechanism 4 is used to dry the cooled hose. Hot air is blown out by a hot air blower 45 and blown to both sides of the hose through branch air ducts 47 to accelerate the evaporation of moisture on the hose surface. Combined with the timely discharge of moisture through the exhaust vent 42, residual moisture on the hose surface and in the gaps of the stranded layers can be quickly removed. This effectively avoids problems such as hose material aging and corrosion of steel wires or fibers caused by moisture, ensuring the flexibility and pressure resistance of the hose. By setting up the traction mechanism 5, the traction motor 56 drives the traction roller 55 to rotate, which, in conjunction with the setting of the lifting roller 54, provides traction force for the hose to move forward. The anti-slip texture on the surfaces of both increases friction and enhances the traction effect. The lifting frame 52 can be raised and lowered by the electric push rod 51, thereby changing the distance between the lifting roller 54 and the traction roller 55. This allows for the traction of hoses of different diameters, increasing the versatility of the device. Furthermore, the lifting frame 52 slides in the groove 48 via the slider 53, which allows for a wider adjustment range of the lifting roller 54 and increases the stability during traction.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
