[0002] After the coil spring is processed and formed, it needs to be treated with rust prevention to prevent rust during long-term storage. Usually, the coil spring is immersed in an oil tank, and a layer of rust-proof oil is covered on the surface of the coil spring for rust prevention. After the coil spring is removed from the oil tank, a large amount of rust-proof oil is attached to the surface. Among them, only a thin layer of rust-proof oil is needed for rust prevention. The excess rust-proof oil actually has little effect in the rust-proof process, and the excess rust-proof oil needs to be cleaned up. Usually, the coil spring is suspended so that the rust-proof oil on the surface of the coil spring drips naturally. In the above operation method, the cleaning speed of the rust-proof oil on the surface of the coil spring is slow. In the actual operation process, some rust-proof oil is difficult to drip down by gravity. The rust-proof oil is not cleaned thoroughly, resulting in a waste of rust-proof oil, which is difficult to meet the processing requirements of the coil spring. Utility Model Content

DETAILED DESCRIPTION
[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0033] like Figure 1-8 The present embodiment shows a coil spring surface drying device, which can be applied to the processing requirements of various coil springs of different specifications and models. The surface drying device includes a drying cylinder 2, an air supply device 1, and a stopper. The drying cylinder 2 is an internal hollow structure, and has a conveying channel 23 extending along a first direction. In the present embodiment, the first direction is defined as the left-right direction. The two ends of the conveying channel 23 are formed with a first open end 21 and a second open end 22 on the drying cylinder 2. The coil spring can enter and exit the conveying channel 23 via the first open end 21 and the second open end 22 in the direction of its length. The conveying channel 23 has a designed length to accommodate a certain number of coil springs.
[0034] A flexible windshield curtain 221 for opening and closing the second open end 22 is hung on the air-drying drum 2. The flexible windshield curtain 221 is a conventional component of the prior art, wherein the flexible windshield curtain 221 is formed by a plurality of strip-shaped separate parts arranged and combined. The second open end 22 is automatically covered by the flexible windshield curtain 221, and the spiral spring in the conveying channel 23 can push open the flexible windshield curtain 221 when moving, so that it can be moved out of the second open end 22.
[0035] The aforementioned stopper is arranged inside the first open end 21, and its upper end is hinged to the top of the air-drying cylinder 2, and the lower end of the stopper forms a free end. The stopper is configured to have an active state in which it is allowed to swing toward the second open end 22, and a stopped state in which it is restricted from swinging toward the outside of the air-drying cylinder 2. During the specific structural design, a limiting structure 24 is formed on the side of the stopper facing the second open end 22 on the air-drying cylinder 2. When the stopper swings toward the outside of the air-drying cylinder 2, the upper end of the stopper abuts against the limiting structure 24 to form a limiting fit, thereby limiting the swinging of the stopper toward the outside of the air-drying cylinder 2. The above-mentioned limiting structure 24 is a limiting side wall formed on the air-drying cylinder 2.
[0036] The aforementioned air supply device 1 is installed on the left side of the air drying cylinder 2, and is installed on a slide rail extending in the left-right direction so as to be able to move left-right. The air supply device 1 moves left-right to have a loading position away from the air drying cylinder 2 and a drying position close to the air drying cylinder 2. The air supply device 1 has a matching end face 12 facing the first open end 21. A blowing port 13 is processed on the matching end face 12. The air flow generated by the air supply device 1 is discharged through the blowing port 13. The above-mentioned air supply device 1 includes a shell 11 and a fan installed inside the shell 11. The aforementioned matching end face 12 is formed on the shell 11. The air outlet end face of the fan is arranged facing the blowing port 13 so as to be able to blow air flow to the blowing port 13. A spring placement position extending in the first direction is connected to the aforementioned matching end face 12. The coil spring can be placed on the spring placement position in a posture extending in the left-right direction. In the specific structural design, two groups of supporting rods 14 extending in the first direction are installed in parallel on the aforementioned matching end face 12. The first ends of the two groups of supporting rods 14 are fixedly connected to the matching end surface 12, and the second ends form free ends. A spring placement position is formed between the two groups of supporting rods 14. A stopper 15 is fixed on the supporting rod 14 at a position close to the matching end surface 12. When the coil spring is placed at the spring placement position, the stopper 15 limits the movement of the coil spring in the direction close to the matching end surface 12. When the air supply device 1 is located at the loading position, the spring placement position is located outside the air drying cylinder 2 so that the coil spring can be placed at the spring placement position. When the air supply device 1 moves from the loading position to the air drying position, the aforementioned matching end surface 12 covers the first opening so that the blowing port 13 is connected to the first open end 21, and the spring placement position is inserted into the interior of the air drying cylinder 2. The airflow generated by the air supply device 1 is blown into the conveying channel 23 through the blowing port 13 so that the coil spring located at the spring placement position and the coil spring located in the conveying channel 23 can be purged.
[0037] According to actual needs, the air supply device 1 includes a heater. The heater is arranged between the air outlet of the fan and the air outlet 13. The airflow discharged from the air outlet 13 is heated by the heater so that the airflow is heated. The hot airflow contacts the coil spring and heats the surface of the coil spring to improve the cleaning effect of the surface anti-rust oil of the coil spring.
[0038] In this embodiment, a driver 3 is installed on one side of the air supply device 1. The driver 3 is connected to the air supply device to drive the air supply device 1 to move along the first direction. The driver 3 is preferably a cylinder, a screw slider mechanism, a gear rack mechanism, etc.
[0039] It should be noted that when the air supply device 1 blows air into the delivery channel 23, since the flexible wind shield 221 cannot completely cover the second open end 22, part of the air flow can be discharged through the second open end 22. In addition, a vent hole 25 is processed on the air drying cylinder 2, and part of the air flow can be discharged through the vent hole 25.
[0040] In this embodiment, during the movement of the air supply device 1 from the loading position to the air-drying position, the stopper first contacts the front end of the coil spring located at the spring placement position to force the stopper to swing in the direction of the second open end 22. When the air supply device 1 reaches the air-drying position, the stopper disengages from the rear end of the coil spring and returns to the initial position, so that the stopper is intercepted between the mating end surface 12 and the spring placement position. During the movement of the air supply device 1 from the air-drying position to the loading position, the stopper first contacts the rear end of the coil spring located at the spring placement position, and the stopper is restricted from swinging, so as to force the coil spring located at the spring placement position to move and disengage from the supporting rod 14, thereby transferring the coil spring to the conveying channel 23.
[0041] In this embodiment, the bottom surface of the aforementioned conveying channel 23 is an inclined surface 231. The inclined surface 231 has an inclined upper end close to the first open end 21 and an inclined lower end close to the second open end 22. Through the above structural design, the coil spring transferred to the conveying channel 23 can automatically slide on the inclined surface 231 toward the second open end 22 to automatically push open the flexible windshield curtain 221 and move out from the second open end 22.
[0042] Among them, the bottom of the above-mentioned air drying cylinder 2 is distributed and processed with oil leakage holes 232 connected to the conveying channel 23. After being purged by air flow in the conveying channel 23, the anti-rust oil blown off by the air flow is discharged through the oil leakage holes 232. A collecting tank 5 is installed below the air supply device 1 and the air drying cylinder 2. The collecting tank 5 can collect the anti-rust oil discharged from the oil leakage holes 232, and can collect the anti-rust oil dripping from the coil spring located at the spring placement position when the material is in the loading position.
[0043] In this embodiment, a loading plate 6 is installed on one or both sides of the air supply device 1 in the second direction. The second direction is the front-to-back direction. The loading plate 6 is tilted up and down and is located on one side of the air supply device 1 in the second direction. When the air supply device 1 is in the loading position, the tilted lower end of the loading plate 6 corresponds to the spring placement position up and down. Through the above structural design, the coil spring can roll down to the spring placement position via the loading plate 6 to automatically load.
[0044] When in use, when the air supply device 1 moves to the loading position, the coil spring to be air-dried is placed on the spring placement position. The air supply device 1 is driven to move to the air-drying position, and the coil spring is sent into the conveying channel 23, and the matching end face 12 of the air supply device 1 covers the first open end 21. In the above process, the stopper swings in the direction of the second open end 22 so as not to block the bolt spring from entering the conveying channel 23. After the coil spring enters the conveying channel 23, the fan operation is started, and strong wind is blown into the conveying channel 23 through the air blowing port 13, so that the surface rust-proof oil of the coil spring in the conveying channel 23 can be blown off and separated, so as to clean up the excess rust-proof oil. The cleaned rust-proof oil falls into the collection tank through the oil leakage hole. After air drying, the air supply device 1 is driven back to the loading position. In the return process, under the action of the stopper, the stopper limits the movement of the coil spring on the spring placement position, so as to force the coil spring to automatically detach from the spring placement position and transfer to the conveying channel 23. Guided by the inclined surface 231, the coil spring in the conveying channel 23 pushes the wind screen and automatically moves out from the second open end 22, so as to realize automatic unloading of the coil spring. The combination of the above methods can blow off the grease on the surface of the coil spring by blowing air, and the grease cleaning is efficient and thorough, which effectively improves the cleaning speed of the surface grease of the coil spring, effectively saves grease, and has strong practicality.
[0045] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
