Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning pipe processing, specifically a spraying device for corrosion protection of automotive air conditioning pipes. Background Technology

[0002] Automotive air conditioning ducts are a key component of the automotive air conditioning system. They are responsible for effectively connecting various components of the automotive air conditioning system, such as the compressor, condenser, evaporator, and expansion valve, to form a closed and orderly working system. In order to improve the corrosion resistance of the ducts, anti-corrosion materials need to be sprayed on the outside of the ducts to extend their service life.

[0003] Traditional methods of applying anti-corrosion materials to the outside of pipes by hand-held spray heads and rotating the pipes not only result in uneven application of the anti-corrosion material, affecting the anti-corrosion effect, but also lead to poor continuity in the application, thus reducing the efficiency of pipe spraying. Therefore, a new technical solution needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a spraying device for corrosion protection of vehicle air conditioning pipes. This device solves the technical problem that the current method of spraying anti-corrosion materials onto the outside of pipes by hand-held spraying heads and rotating the pipes not only results in uneven application of anti-corrosion materials on the outside of the pipes, but also affects the anti-corrosion effect of the pipes.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A spraying device for corrosion protection of automotive air conditioning pipes is designed, including a processing table. Sprockets are rotatably connected to both sides of the surface of the processing table. A chain is arranged between two sprockets. An annular slide rail is installed on the processing table outside the chain. Multiple sliders are slidably sleeved on the outer side of the annular slide rail. A connecting rod is fixedly connected to one end of each slider near the chain, and the connecting rods are connected to the surface of the chain. A fixed cylinder is rotatably connected to the top of each slider via a connecting shaft. Gears are fixedly connected to the outer side of the connecting shaft below each fixed cylinder. Racks are fixedly connected to both sides of the surface of the processing table, and the gears mesh with the racks. A housing is fixedly connected between the two sides of the processing table. A partition is fixedly connected to the middle of the top of the inner cavity of the housing. A spraying mechanism is arranged inside the housing on one side of the partition.

[0006] Preferably, the spraying mechanism includes a storage tank installed on the top of the housing and a paint spraying pipe installed in the inner cavity of the housing and on one side of the partition. Each of the two paint spraying pipes is connected to a plurality of atomizing paint spraying heads at opposite ends. A paint pump is connected to the storage tank through a connecting pipe, and a feed pipe is connected between the outlet end of the paint pump and the paint spraying pipe.

[0007] Preferably, a hot air blower is installed on one side of the top of the housing, and the hot air end of the hot air blower is connected to a hot air duct. The hot air duct is located above the inner cavity of the housing and is arc-shaped.

[0008] Preferably, a blower is installed on the top of the housing away from the storage bin, and the air outlet of the blower is connected to an air outlet pipe, which passes through the housing and is connected to an air jet pipe.

[0009] Preferably, a shielding curtain is installed above the feed inlet of the housing, and the shielding curtain is transparent.

[0010] Preferably, the fixing cylinder is conical, and a rubber pad is fixedly connected to the outer side of the fixing cylinder.

[0011] Preferably, a drive motor is installed on one side of the bottom of the processing table, and the drive end of the drive motor is connected to the center of one of the sprockets.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a drive motor, sprocket, chain, annular slide rail, slider, connecting rod, gear, rack, fixed cylinder, and spraying mechanism. The vehicle air conditioning duct to be sprayed is fitted onto the outside of the fixed cylinder and connected to the gear. The drive motor is then activated to move the slider at a constant speed. When the slider moves the vehicle air conditioning duct to the rack side, the gear contacts the rack, causing the fixed cylinder and the vehicle air conditioning duct to rotate. Thus, the vehicle air conditioning duct rotates at a constant speed while moving at a constant speed. Simultaneously, the spraying mechanism is activated to spray anti-corrosion paint onto the outside of the vehicle air conditioning duct, thereby improving the anti-corrosion effect and enhancing the quality of corrosion protection for the vehicle air conditioning duct. Furthermore, the continuous cyclical movement of the slider and fixed cylinder allows for continuous spraying of the vehicle air conditioning duct, further improving spraying efficiency.

[0014] 2. This utility model combines a hot air blower, a hot air duct, a blower, and an air outlet duct. When the vehicle air conditioning pipe is painted and moved below the hot air duct, hot air is blown out by the hot air blower through the hot air duct to dry the painted vehicle air conditioning pipe, thereby accelerating the drying speed of the paint. Then, when the dried vehicle air conditioning pipe is moved below the air outlet duct, the blower is activated to blow air through the air outlet duct to quickly cool the dried vehicle air conditioning pipe, making it easier for personnel to pick up the dried vehicle air conditioning pipe.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A spraying device for corrosion protection of automotive air conditioning ducts, see [link / reference] Figures 1 to 4The system includes a processing table 1, on both sides of which are rotatably connected to sprockets 13. A drive motor 11 is mounted on one side of the bottom of the processing table 1, and the drive end of the drive motor 11 is connected to the center of one of the sprockets 13. A chain 14 is arranged between the two sprockets 13. An annular slide rail 12 is mounted on the processing table 1 outside the chain 14. Multiple sliders 31 are slidably sleeved on the outer side of the annular slide rail 12. Each slider 31 is fixedly connected to a connecting rod 33 near the end of the chain 14, and each connecting rod 33 is connected to the chain 14. The surface is connected, and the tops of the multiple sliders 31 are rotatably connected to fixed cylinders 34 via connecting shafts. Gears 32 are fixedly connected to the outer sides of the connecting shafts below the multiple fixed cylinders 34. Racks 3 are fixedly connected to both sides of the surface of the processing table 1, and the gears 32 mesh with the racks 3. A housing 2 is fixedly connected between the two sides of the processing table 1. A partition 21 is fixedly connected to the middle of the top of the inner cavity of the housing 2. A spraying mechanism is provided inside the housing 2 on one side of the partition 21. The spraying mechanism includes a storage box 4 installed on the top of the housing 2 and a material storage box 4 installed in the inner cavity of the housing 2 and the partition 4. On one side of the 21 spray pipe 43, multiple atomizing spray heads are connected to opposite ends of both spray pipes 43. A paint pump 41 is connected to the storage tank 4 via a connecting pipe. A feed pipe 42 connects the outlet end of the paint pump 41 to the spray pipe 43. During operation, the drive motor 11 is started to drive the sprocket 13 to rotate at a constant speed, which in turn, in conjunction with the chain 14 and connecting rod 33, drives the slider 31 to move at a constant speed on the annular slide rail 12. Then, the vehicle air conditioning pipe to be sprayed is sleeved on the outside of the fixed cylinder 34 and connected to the gear 32. When the slider 31 drives the vehicle air conditioning pipe to move to the outside of the fixed cylinder 34, the vehicle air conditioning pipe is moved to the fixed cylinder 32. When the rack 3 is in contact with the rack 3, the gear 32 contacts the rack 3, causing the fixed cylinder 34 and the vehicle air conditioning pipe to rotate. As the slider 31 moves at a constant speed, the vehicle air conditioning pipe rotates at a constant speed while moving at a constant speed. At the same time, the paint pump 41 is started to spray the anti-corrosion paint in the storage tank 4 through the atomizing nozzle 44 onto the outside of the vehicle air conditioning pipe, which is moving and rotating at a constant speed. This improves the effect of the anti-corrosion paint spraying and further improves the quality of anti-corrosion of the vehicle air conditioning pipe. Furthermore, the continuous cyclical movement of the slider 31 and the fixed cylinder 34 enables continuous spraying of the vehicle air conditioning pipe, further improving the spraying efficiency.

[0022] For details, see Figure 1 and Figure 2A hot air blower 6 is installed on one side of the top of the housing 2. The hot air end of the hot air blower 6 is connected to a hot air duct 61. The hot air duct 61 is located above the inner cavity of the housing 2 and is arc-shaped. A blower 5 is installed on the top side of the housing 2 away from the storage box 4. The air outlet end of the blower 5 is connected to an air outlet pipe 51. The air outlet pipe 51 passes through the housing 2 and is connected to a jet pipe 52. When the vehicle air conditioning pipe is painted and moved below the hot air duct 61, hot air is sprayed out by the hot air blower 6 through the hot air duct 61 to dry the painted vehicle air conditioning pipe, thereby accelerating the drying speed of the paint. Then, when the dried vehicle air conditioning pipe is moved below the air outlet pipe 51, the blower 5 is started to blow air through the air outlet pipe 51 to quickly cool down the dried vehicle air conditioning pipe, making it easier for personnel to pick up the dried vehicle air conditioning pipe.

[0023] Further, see Figure 3 A shielding curtain 7 is installed above the feed inlet of the housing 2, and the shielding curtain 7 is transparent. By setting the shielding curtain 7, the splashing of anti-corrosion paint during spraying can be effectively avoided, thus preventing work pollution.

[0024] It is worth noting that, see Figure 4 The fixing cylinder 34 is conical, and a rubber pad 35 is fixedly connected to the outside of the fixing cylinder 34. The conical shape of the fixing cylinder 34 facilitates the placement of the vehicle air conditioning pipe on the outside of the fixing cylinder 34 and its connection to the gear 32. At the same time, the rubber pad 35 increases the friction between the fixing cylinder 34 and the inside of the vehicle air conditioning pipe, thereby improving the stability of the connection between the vehicle air conditioning pipe and the fixing cylinder 34.
