Description

Technical Field

[0001] The present application belongs to the technical field of hose manufacturing, and in particular relates to a conformal hose dyeing device. Background Art

[0002] Conformal hose is a special hose woven with polyolefin hard wire, polyamide wire and other materials with certain rigidity as the weft. Unlike traditional hoses woven with polyester fiber as the weft, it can maintain its round shape in its natural state without pressure, so it is also called conformal hose.

[0003] The raw materials of conformal hoses are generally made of original fiber colors (mostly white). A few products that require specific colors are woven directly with colored fibers. However, colored fibers are expensive and need to be purchased in advance, which greatly prolongs the product delivery cycle and cost. If they are stockpiled in advance, they are likely to accumulate and occupy inventory space. If they are woven directly with original fiber colors and then dyed as needed, production efficiency can be effectively improved, which is more suitable for factory production. However, using ordinary hose dyeing equipment will flatten the pipe and cause deformation, which cannot meet the needs of conformal hose dyeing. Utility Model Content

[0004] In order to solve the technical problem that the dyeing equipment in the prior art cannot meet the dyeing requirements of conformal hoses, the present application provides a conformal hose dyeing device.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is a shape-keeping hose dyeing device, comprising

[0006] a conveying mechanism for conveying the conformable hose;

[0007] A spraying mechanism, used for spraying dye on the surface of the conformal hose;

[0008] A drying mechanism, used for drying and curing the dye on the surface of the conformal hose;

[0009] The conveying mechanism comprises a conveying unit, and the conveying unit comprises a mounting frame and an upper rubber roller and a lower rubber roller rotatably arranged on the mounting frame, and the upper rubber roller and the lower rubber roller both have a limiting groove on the surface matching the shape of the hose;

[0010] The drying mechanism comprises an oven and a hot air source. A hot air inlet connected to the hot air source is arranged on the oven, and an air distribution structure is arranged inside the oven.

[0011] In one embodiment, the air distribution structure is a mesh plate disposed in the oven, and the mesh plate is located between the hot air inlet and the conformal hose located in the oven.

[0012] In one embodiment, a baffle is further provided at the hot air inlet, and the baffle deviates from the extending direction of the hot air inlet.

[0013] In one embodiment, the spraying mechanism includes a dyeing tank and at least two groups of spraying units. The direction of the spraying units is the same as the axial direction of the conformal hose. The upper and lower parts of the dyeing tank are both provided with the spraying units. The spraying unit is composed of a conveying pipeline and a plurality of nozzles arranged on the conveying pipeline, and the nozzles are arranged towards the conformal hose.

[0014] In some embodiments, a collecting tank is further provided at the bottom of the dyeing tank, and one end of the collecting tank has a discharge port.

[0015] In some embodiments, a plurality of the limiting grooves are distributed on the upper sizing roller and the lower sizing roller.

[0016] In some embodiments, the number of the conveying units is two. One of the conveying units is located at the input end of the spraying mechanism, and the other conveying unit is located at the output end of the drying mechanism.

[0017] In some embodiments, the conveying unit further includes a power mechanism, and the power mechanism drives the upper sizing roller and the lower sizing roller to rotate.

[0018] In some embodiments, a cooling mechanism is further provided between the output end of the drying mechanism and the conveying unit adjacent to the drying mechanism.

[0019] Beneficial effects: In this application, sizing rollers are used for conveying, and limiting grooves matching the conformal hose are opened on the surfaces of the sizing rollers. The elasticity of the sizing rollers can effectively reduce the possibility of the conformal hose being squeezed and deformed during the dyeing process, so that the shape of the conformal hose is kept good. Spraying and drying equipment is used for dyeing, with high production efficiency and uniform dyeing. At the same time, a air distribution structure is arranged in the oven, so that the hot air can be evenly distributed in the oven, improving the temperature consistency in the oven and being more conducive to the drying and curing of the dye.

[0023] The present application will be further described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in the present application without making creative changes belong to the protection scope of the present application.

[0024] As Figure 1 and 2 shown, a conformal hose dyeing device includes

[0025] a conveying mechanism 1 for conveying a conformal hose;

[0026] a spraying mechanism for spraying dye on the surface of the conformal hose;

[0027] a drying mechanism for drying and curing the dye on the surface of the conformal hose;

[0028] The conveying mechanism 1 includes a conveying unit, and the conveying unit includes a mounting frame and an upper rubber roller 11 and a lower rubber roller 12 rotatably arranged on the mounting frame. The surfaces of both the upper rubber roller 11 and the lower rubber roller 12 have a limiting groove 13 matching the shape of the hose;

[0029] The drying mechanism includes an oven 3 and a hot air source. A hot air inlet 33 communicating with the hot air source is arranged on the oven 3, and a air distribution structure is arranged in the oven 3.

[0030] In the present application, the conformal hose is conveyed by the conveying mechanism 1. Since the surface of the rubber roller is elastic, conveying the conformal hose by the rubber roller can not only play a conveying role, but also ensure the shape of the conformal hose and prevent it from being flattened. Then it enters the spraying mechanism to spray the dye, and then enters the drying mechanism to dry and cure, and then a dyed product can be obtained. Since an air distribution structure is arranged in the drying mechanism, the hot air can be distributed more evenly in the drying mechanism.

[0031] The hot air source is composed of a blower 34 and an electric heating module 35. After the electric heating module 35 is powered on, it generates heat, which is sent into the hot air inlet 33 by the blower 34.

[0032] Specifically, in some embodiments, the air distribution structure is a mesh plate 31 disposed in the oven 3, and the mesh plate 31 is located between the hot air inlet 33 and the conformal hose located in the oven 3. The mesh plate 31 divides the internal space of the oven 3 into two regions, namely the air distribution region and the drying region. The hot air entering from the hot air inlet 33 is blocked by the mesh plate 31 and distributed in the air distribution region, and at the same time, it passes through the mesh holes on the mesh plate 31 into the drying region, reducing the temperature difference between the drying region far from the hot air inlet 33 and the drying region close to it, and improving the temperature uniformity. Further, the size of the mesh holes on the mesh plate 31 can also be set to adjust the temperature difference in the drying area. Specifically, mesh holes with a smaller density can be set at the position of the mesh plate 31 close to the hot air inlet 33, and mesh holes with a higher density can be set at the position far from the hot air inlet 33.

[0033] In some embodiments, in order to further improve the temperature uniformity, a baffle plate 32 is also provided at the hot air inlet 33, and the baffle plate 32 extends in a direction deviating from the extension direction of the hot air inlet 33. The baffle plate 32 can be used to change the flow path of the hot air, that is, change the distribution of the hot air, and avoid the temperature difference caused by the concentration of the hot air. A temperature sensor 36 can also be provided in the oven 3 to detect the temperature in the oven 3.

[0034] In some embodiments, specifically, the spraying mechanism includes a dyeing tank 2 and at least two groups of spraying units. The direction of the spraying units is the same as the axial direction of the conformal hose. The upper and lower parts of the dyeing tank 2 are both provided with the spraying units. The spraying unit is composed of a conveying pipe 21 and a plurality of nozzles 22 provided on the conveying pipe 21, and the nozzles 22 are arranged facing the conformal hose. For example, in some embodiments, two groups of spraying units are provided, and the two spraying units are respectively located directly above and directly below the conformal hose. In some embodiments, four groups of spraying units can also be provided, and the four spraying units are respectively located obliquely above and obliquely below the conformal unit to ensure the uniformity of spraying at all angles.

[0035] Not all of the ejected dye is coated on the surface of the conformal hose. In order to facilitate the collection of the excess dye, in some embodiments, a collection tank 23 is further provided at the bottom of the dyeing tank 2, and one end of the collection tank 23 has a discharge port 24.

[0036] In order to facilitate the simultaneous production of multiple pipes, in some embodiments, a plurality of the limiting grooves 13 (not shown in the figure) are distributed on the upper sizing roller 11 and the lower sizing roller 12. Correspondingly, the number of spraying units and the processing capacity of the drying mechanism should be increased to ensure the spraying and drying effects.

[0037] In some embodiments, the number of the conveying units is two. One of the conveying units is located at the input end of the spraying mechanism, and the other conveying unit is located at the output end of the drying mechanism. The conveying unit further includes a power mechanism 14, and the power mechanism 14 drives the upper rubber roller 11 and the lower rubber roller 12 to rotate. Conveying units with power are provided at both the front end and the rear end of the device. During use, the conveying speeds of the two conveying units are the same, which can keep the conformal hose in a straightened state in the spraying mechanism and the drying mechanism, facilitating the spraying and drying effects.

[0038] To avoid the dye on the surface of the conformal hose still being in a relatively high temperature state and having a certain plasticity after drying, which is likely to deform under the extrusion of the rubber roller, in some embodiments, a cooling mechanism (not shown in the figure) is further provided between the output end of the drying mechanism and the conveying unit adjacent to the drying mechanism. The cooling mechanism can be used to cool down the conformal hose with a dye coating after drying, so that the coating is cured and the deformation of the dye coating is avoided. The specific cooling mechanism can be water cooling or air cooling.

[0039] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of this application.
