Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, and in particular to a spraying device for processing power control cables. Background Art

[0002] Cable is an insulated conductor composed of one or more mutually insulated conductive cores placed in a sealed sheath, which may be covered with a protective layer. It is used to transmit and distribute electrical energy or transmit electrical signals. During cable processing and production, it is necessary to spray paint on the cable surface to play an anti-corrosion or fire-proof role and extend the service life of the cable.

[0003] The existing authorization announcement number is CN214320672U, "A spray device for processing electric control cables", which includes a base, a nozzle adjustment unit, a temperature adjustment unit, a drying tube and a nozzle; the base: a fixed plate is fixed to the rear side of the top surface through a support rod, a drying tube is fixed to the middle part of the fixed plate, a fixed ring is fixed to the front side of the top surface of the base through a support rod, the fixed ring and the drying tube are connected by a connecting rod, and the axis of the drying tube is concentric with the center of the fixed ring; drying tube: the front side of the top surface is connected to an auxiliary heat pipe through a connecting pipe, and the rear side of the top surface is connected to an air inlet pipe. The spray device for processing electric control cables can not only adjust the temperature, which is convenient to use, but also can recover heat, which is more energy-saving, and can adjust the nozzle position according to cables of different thicknesses, and has a wide range of applications.

[0004] When the above technical solution is adopted, during use, the cable after spraying directly passes through the drying tube, and a heating tube is arranged inside the drying tube. Although the heating tube can directly heat and dry the cable after spraying, the undried paint will drip into the heating tube along the cable. Long-term use of the paint will cause irreversible damage to the heating tube. Although the design of the air inlet pipe and the auxiliary heating pipe can preheat the drying air source, the gas evaporated by the heating of the paint will condense when it is cooled. Long-term use will cause the outer wall of the air inlet pipe to be filled with viscous lipid substances, and the preheating effect will be greatly reduced. At the same time, the second fan will also increase the power consumption due to the viscous lipid substances, and the viscous lipid substances are extremely difficult to remove, thereby reducing the service life of the equipment. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the practical embodiment clearer, the technical solution in the practical embodiment is clearly and completely described. Obviously, the described embodiment is a part of the practical embodiment, not all of the embodiments. Based on the embodiments in this practical, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical.

[0024] The embodiment of the present application provides a spraying device for processing power control cables, which solves the technical problem that the dripping and volatilization and condensation of paint on the sprayed cables during drying affects the normal operation of the equipment. When in use, isolation between the heating tube and the paint is achieved, which increases the service life of the equipment while improving the efficiency of heat utilization and the working efficiency of the drying unit.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-2 A spraying device for processing power control cables comprises: a base 1, a plurality of support columns 2 are connected to the upper part of the base 1, and the plurality of support columns 2 are placed vertically to the base 1; a drying unit 11, the drying unit 11 is fixedly connected to the support columns 2, the drying unit 11 comprises an air inlet pipe 3, a drying pipe 4 and a preheating pipe 5, the drying pipe 4 is located inside the preheating pipe 5, a plurality of support rods 6 are arranged between the outer side of the drying pipe 4 and the inner side of the preheating pipe 5, a fan 7 is connected to one end of the air inlet pipe 3, an air source dispersion pipe 8 is connected to the other end of the air inlet pipe 3, the air source dispersion pipe 8 is fixedly connected to one end of the preheating pipe 5, a heating pipe 9 is connected to the middle of the plurality of support rods 6, and an annular guide sheet 10 is arranged at the other end of the preheating pipe 5.

[0027] The design of the base 1 and the support column 2 improves the stability of the drying unit 11 during operation. The settings of the air inlet pipe 3, the drying pipe 4 and the preheating pipe 5 determine the air flow path, ensuring that the fallen paint and the condensed viscous lipid substances will not contact the heating pipe 9, thereby increasing the service life of the device. The setting of the air source dispersion pipe 8 can evenly disperse the air from the air inlet pipe 3 in the space between the drying pipe 4 and the preheating pipe 5, ensuring sufficient contact between the air and the heating pipe 9 and improving the air heating efficiency. The setting of the support rod 6 ensures that a stable heating channel is formed between the drying pipe 4 and the preheating pipe 5, ensuring smooth air flow. The setting of the annular guide plate 10 guides the heated air into the drying pipe 4.

[0028] In a further embodiment, the drying unit 11 has an angle of 0°-10° with the horizontal plane, and one end of the drying unit 11 located on the annular guide sheet 10 is higher than the other end of the drying unit 11 .

[0029] The drying unit 11 has an angle of 0°-10° with the horizontal plane, that is, the drying tube 4 has a certain angle with the horizontal plane. When the paint on the cable surface drips into the drying tube 4, the paint moves along the bottom of the drying tube 4 to the lower end of the drying tube 4 for collection. Since the annular guide plate 10 blows hot air into the drying tube 4, the drying unit 11 is located at one end of the annular guide plate 10 higher than the other end of the drying unit 11, ensuring that the dripping paint will not pass through the annular guide plate 10 into between the drying tube 4 and the preheating tube 5, thereby ensuring the stability of the operation of the drying unit 11.

[0030] In a further embodiment, the length of the drying tube 4 is greater than that of the preheating tube 5 , and the drying tube 4 and the preheating tube 5 are located on the same vertical plane at one end adjacent to the annular guide plate 10 .

[0031] The length of the drying tube 4 is greater than that of the preheating tube 5. The drying tube 4 and the preheating tube 5 are located on the same vertical plane at one end adjacent to the annular guide plate 10, that is, the lower end of the drying tube 4 is ensured to exceed the lower end of the preheating tube 5, so that the paint located at the lower end of the drying tube 4 will not contaminate the surface of the preheating tube 5 and the air source dispersion tube 8, and the surface of the drying unit can be kept clean.

[0032] In a further embodiment, the air source dispersion pipe 8 is circular and hollow inside, the outer side of the air source dispersion pipe 8 is fixedly connected to one end of the heating pipe 9, the inner side of the air source dispersion pipe 8 is fixedly connected to the outer side of the drying pipe 4, and a plurality of air supply ports 12 are provided on the air source dispersion pipe 8, and the air supply ports 12 are located inside the preheating pipe 5.

[0033] The air source dispersion pipe 8 is circular and hollow inside, and the air from the air inlet pipe 3 can be evenly dispersed inside the air source dispersion pipe 8. The outer side of the air source dispersion pipe 8 is fixedly connected to one end of the heating pipe 9, and the inner side of the air source dispersion pipe 8 is fixedly connected to the outer side of the drying pipe 4, which can ensure the sealing of one end between the heating pipe 9 and the drying pipe 4 to prevent the heated air from flowing back and causing energy waste. A plurality of air supply ports 12 are provided on the air source dispersion pipe 8, and the air supply port 12 is located inside the preheating pipe 5. The air in the air source dispersion pipe 8 can be evenly dispersed in the space between the drying pipe 4 and the preheating pipe 5 to ensure full contact between the air and the heating pipe 9 and improve the air heating efficiency.

[0034] In a further embodiment, the annular guide plate 10 is in a circular shape, one end of the annular guide plate 10 is fixedly connected to one end of the preheating tube 5 , and the other end of the annular guide plate 10 is located inside the drying tube 4 .

[0035] The setting of the annular guide plate 10 can guide the hot air from between the drying tube 4 and the preheating tube 5 to the inside of the drying tube 4, and blow the hot air from the higher end of the drying tube 4 to the lower end of the drying tube 4. The movement direction of the cable is from the lower end of the drying tube 4 to the higher end of the drying tube 4, so the cable heating moves from the lower temperature area to the higher temperature area. This heating method can improve the utilization rate of the hot air by the drying unit 11, improve the drying degree of the coating, and prevent the coating from being falsely dried.

[0036] In a further embodiment, the drying tube 4 and the preheating tube 5 are both fixedly connected to the support rods 6 , a plurality of support rods 6 are evenly distributed between the drying tube 4 and the preheating tube 5 , and a temperature sensor 13 is provided on the inner wall of the preheating tube 5 .

[0037] The setting of the support rod 6 ensures that a stable heating channel is formed between the drying tube 4 and the preheating tube 5, ensures smooth air flow, increases the air heating rate, and improves energy utilization. The setting of the temperature sensor 13 can detect the air temperature in real time. When the temperature reaches the set value, the output power of the heating tube 9 is reduced to reduce energy consumption.

[0038] In a further embodiment, a guide pipe 14 is connected to one end of the drying pipe 4 adjacent to the gas source dispersion pipe 8 . The guide pipe 14 is located at the bottom of the drying pipe 4 and is fixedly connected to the drying pipe 4 .

[0039] The guide pipe 14 is located at the bottom of the drying pipe 4 and is fixedly connected to the drying pipe 4. The paint moving to the lower end of the drying pipe 4 can be collected to prevent the paint from splashing and polluting the production environment.

[0040] In a further embodiment, a spraying unit 15 is disposed on one side of the drying unit 11 , and the spraying unit 15 is fixedly connected to the base 1 .

[0041] The spraying unit 15 is located on one side of the drying unit 11 and is fixedly connected to the base 1, so that the cable can enter the drying unit 11 for drying in time after spraying, thereby improving the convenience of use of the equipment and facilitating operation.

[0042] During use, the fan rotates to blow air into the air source dispersion pipe, and the air moves evenly to the space between the drying pipe and the preheating pipe through multiple air supply ports. The setting of the support rod ensures the relative stability of the drying pipe and the preheating pipe. The heating pipe in the middle of the support rod heats the air in the space to change it from cold air to hot air. The temperature sensor detects the air temperature in real time. When the temperature reaches the set value, the output power of the heating pipe is reduced to reduce energy consumption. The hot air moves to the annular guide plate and is guided into the inside of the drying pipe by the annular guide plate. The hot air moves along the inside of the drying pipe to the guide pipe and is discharged. After being sprayed by the spray unit, the cable passes through the drying pipe and connects one end of the guide pipe and then goes out from the other end of the drying pipe. The dripping paint moves along the bottom of the drying pipe to the guide pipe and is collected through the guide pipe.

[0043] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. The inclined setting of the drying unit can make the paint dripping in the drying tube automatically move to the lower end of the drying tube without affecting the drying unit. The dripping paint flows along the bottom of the drying tube to the guide pipe for collection, thereby improving the cleanliness of the equipment during use.

[0045] 2. The preheating tube is located outside the drying tube. The heating tube also preheats the drying tube during heating, which improves energy utilization and reduces energy consumption. At the same time, the heated dry gas is guided into the drying tube through the annular guide plate to directly heat the paint on the surface of the cable in the drying tube, which can prevent direct contact between the heating tube and the paint and increase the service life of the drying unit.

[0046] 3. The setting of the annular guide piece can make the coating on the cable contact with the hot air evenly, improve the working efficiency of the drying unit, and the movement direction of the hot air is opposite to the movement direction of the cable, which can improve the utilization rate of the hot air by the drying unit, improve the drying degree of the coating, and prevent the phenomenon of false drying of the coating.
