Description

Technical Field

[0001] This utility model relates to a coating equipment for the outer contour of a reciprocating air compressor valve plate, belonging to the technical field of air compressor parts production equipment. Background Technology

[0002] The valve plate of a reciprocating air compressor is one of the core components of the air compressor. Its flatness and surface quality are directly related to the sealing performance and working efficiency of the whole machine. In order to improve the corrosion resistance and wear resistance of the outer contour of the valve plate, it is usually necessary to perform surface coating treatment such as phosphating.

[0003] However, existing valve plates are generally quite thin, typically between 3 and 5 millimeters. With current processes, when the coating liquid is applied to the outer contour surface, it easily adheres to the upper and lower sealing surfaces of the valve plate. Once the coating liquid contaminates the surface, even a small amount remaining can form bumps or cause localized micro-deformation after drying or curing, compromising the flatness of the valve plate. This results in poor sealing after assembly with the valve disc or cylinder, leading to gas leakage.

[0004] Secondary cleaning to address this contamination problem, whether through mechanical scraping or chemical cleaning, carries the risk of damaging the inherent surface roughness of the sealing surface, which can also cause irreversible damage to the sealing performance.

[0005] Therefore, a reciprocating air compressor valve plate outer contour coating equipment is needed to solve the problems of valve plate flatness damage and reduced sealing performance caused by coating fluid contamination. Utility Model Content

[0006] The purpose of this utility model is to provide a coating device for the outer contour of a reciprocating air compressor valve plate, so as to improve or solve the technical problems existing in the prior art as described above. The device can control the coating range of the coating liquid, ensuring that a uniform coating is formed only on the outer contour surface of the valve plate, without contaminating the upper and lower sealing planes of the valve plate, thereby avoiding the problems of flatness damage and sealing performance degradation caused by coating liquid contamination.

[0007] The technical solution provided by this utility model is as follows: A reciprocating air compressor valve plate outer contour coating device includes a worktable, and further includes a synchronous drive mechanism, two spaced idler rollers, a coating roller, and a liquid storage tank disposed on the worktable. The synchronous drive mechanism is connected to the idler rollers for driving the two idler rollers to rotate synchronously. At least one annular groove is provided on the circumferential surface of the idler roller for supporting the valve plate and suspending the outer contour of the valve plate in the air. The liquid storage box is disposed below the idler rollers, and the liquid storage box has an opening at the top. The coating roller is rotatably disposed in the liquid storage box, and the top roller surface of the coating roller is used to contact the suspended outer contour of the valve plate.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes a drying device, which is set on the workbench for drying the outer contour of the coated valve plate.

[0010] The advantage of adopting the above-mentioned further solution is that the air drying device allows the valve plate to enter the drying process immediately after coating, avoiding the possibility of liquid flowing due to gravity and contaminating the uncoated areas of the valve plate.

[0011] Furthermore, a slide rail is provided below the roller, and the liquid storage box is slidably disposed on the slide rail. It also includes a drive cylinder, which is used to drive the liquid storage box to move the coating roller closer to or away from the valve plate.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by driving the liquid storage box to slide as a whole by the cylinder, the contact and separation between the coating roller and the outer contour of the valve plate can be controlled. When coating is required, the coating roller is driven to move closer to the valve plate; when coating is completed, the coating roller can be moved away from the valve plate to avoid unnecessary wetting and dripping.

[0013] Furthermore, the coating roller is a sponge roller or a felt roller.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the material used for the coating roller has good adsorption properties, which can uniformly release the coating liquid when in contact with the valve plate, preventing liquid splashing or local accumulation, and ensuring the continuity and uniformity of the coating.

[0015] Furthermore, the synchronous drive mechanism includes a motor, a first driving wheel, a second driving wheel, a first driven wheel, and a second driven wheel. The first driving wheel and the second driving wheel are coaxially mounted on the output shaft of the motor. The first driving wheel and the first driven wheel are connected by a first belt, and the second driving wheel and the second driven wheel are connected by a belt. One end of each of the two idlers is fixedly connected to the first driven wheel and the second driven wheel, respectively.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by using a single motor in conjunction with two sets of pulleys to synchronously drive the two idler rollers, the rotation speed of the two idler rollers is synchronized, so that the valve plate is subjected to uniform force during rotation and there will be no relative sliding or jamming between it and the idler rollers, thereby ensuring the uniformity and consistency of coating.

[0017] Furthermore, the workbench is also equipped with a valve plate stacking device, which includes a stacking base and a stacking rod vertically arranged on the stacking base. The stacking rod is used to pass through the center hole of multiple stacked valve plates.

[0018] The beneficial effect of adopting the above-mentioned further solution is that multiple valve plates can be neatly stacked on the stacking rod, and by covering them with the upper cover plate and clamping them, they can be sent into the spray booth as a whole as a unit, and then the paint can be sprayed on the outside to prevent contamination of the upper and lower sealing surfaces of the valve plates.

[0019] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The coating equipment of this utility model supports and drives the valve plate to rotate by synchronously rotating rollers, and uses the coating roller in the liquid storage box to coat the outer contour of the suspended and exposed valve plate. This can achieve fast and accurate coating of the outer contour of the valve plate without contaminating the upper and lower sealing surfaces of the valve plate, ensuring the flatness and sealing performance of the valve plate, and at the same time greatly improving production efficiency and product qualification rate.

Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0025] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0026] like Figures 1-6 As shown, the technical solution provided by this utility model is as follows: A reciprocating air compressor valve plate 12 outer contour coating device includes a workbench 1, and further includes a synchronous drive mechanism 2, two spaced idler rollers 3, a coating roller 4, and a liquid storage tank 5 disposed on the workbench 1. The synchronous drive mechanism 2 is connected to the idler rollers 3 for driving the two idler rollers 3 to rotate synchronously. At least one annular groove 6 is provided on the circumferential surface of the idler rollers 3 for supporting the valve plate 12 and exposing the outer contour of the valve plate 12. The liquid storage box is disposed below the idler rollers 3, and the liquid storage box has an opening at the top. The coating roller 4 is rotatably disposed in the liquid storage box, and the top roller surface of the coating roller 4 is used to contact the suspended outer contour of the valve plate 12, so that when the valve plate 12 rotates with the idler rollers 3, its outer contour can be coated with the coating liquid through the coating roller 4.

[0027] The embodiments of this utility model do not limit the number of annular grooves 6 on the circumferential surface of the idler roller 3. One or more annular grooves 6 can be provided. When multiple annular grooves 6 are provided, multiple valve plates 12 can be placed and rotated at the same time to perform coating operations.

[0028] The coating equipment also includes a drying device 7, which is mounted on the workbench 1 and is used to dry the outer contour of the coated valve plate 12. The drying device 7 allows the valve plate 12 to immediately enter the drying process after coating, avoiding liquid from flowing due to gravity and potentially contaminating the uncoated areas of the valve plate 12.

[0029] A slide rail 8 is provided below the idler roller 3, and the liquid storage box is slidably mounted on the slide rail 8. A drive cylinder 9 is also included, which drives the liquid storage box to move the coating roller 4 closer to or away from the valve plate 12. By driving the liquid storage box to slide as a whole, the contact and separation between the coating roller 4 and the outer contour of the valve plate 12 can be controlled. When coating is required, the coating roller 4 is driven closer to the valve plate 12; after coating is completed, the coating roller 4 is moved away from the valve plate 12 to avoid unnecessary wetting and dripping.

[0030] In this embodiment, the coating roller 4 is a sponge roller or a felt roller. The material used for the coating roller 4 has good adsorption properties, which can uniformly release the coating liquid when in contact with the valve plate 12, preventing liquid splashing or local accumulation, and ensuring the continuity and uniformity of the coating.

[0031] The synchronous drive mechanism 2 includes a motor 21, a first driving wheel 22, a second driving wheel 23, a first driven wheel 24, and a second driven wheel 25. The first driving wheel 22 and the second driving wheel 23 are coaxially mounted on the output shaft of the motor 21. The first driving wheel 22 and the first driven wheel 24 are connected by a first belt, and the second driving wheel 23 and the second driven wheel 25 are connected by a belt. One end of each of the two idler rollers 3 is fixedly connected to the first driven wheel 24 and the second driven wheel 25, respectively. By using a single motor 21 in conjunction with two sets of pulleys to synchronously drive the two idler rollers 3, the rotational speed of the two idler rollers 3 is synchronized, ensuring that the valve plate 12 is subjected to uniform force during rotation and preventing relative slippage or jamming between it and the idler rollers 3, thereby ensuring the uniformity and consistency of the coating.

[0032] The workbench 1 is also equipped with a valve plate 12 stacking device, which includes a stacking base 10 and a stacking rod 11 vertically arranged on the stacking base 10. The stacking rod 11 is used to pass through the center hole of multiple stacked valve plates 12. Multiple valve plates 12 are neatly stacked on the stacking rod 11, and clamped by covering with an upper cover plate 13 and putting nuts 14 on the stacking rod 11. They can then be sent into the paint booth as a whole as a unit, and then painted on the outside to prevent contamination of the upper and lower sealing surfaces of the valve plates 12.

[0033] The working method of the reciprocating air compressor valve plate 12 outer contour coating device of this utility model is as follows: First, a coating liquid of a predetermined type is poured into the storage box, so that the lower roller surface of the coating roller 4 is continuously and evenly immersed in the coating liquid. Then, the valve plate 12 to be treated is placed on two spaced-apart support rollers 3, so that the valve plate 12 is stably supported in the annular grooves 6 of the two support rollers 3.

[0034] The control cylinder 9 is activated, causing the liquid storage box to move along the slide rail 8 towards the valve plate 12, thereby bringing the coating roller 4 into contact with the valve plate 12. The drive mechanism is activated, causing the two rollers 3 to rotate synchronously and in the same direction. Through friction, the valve plate 12 rotates at a uniform speed. The coating roller 4, which is soaked in the coating liquid, contacts the outer contour of the valve plate 12 at its top. During this process, the coating roller 4 continuously and uniformly transfers the coating liquid adsorbed on its surface to the outer contour surface of the rotating valve plate 12. At the same time, the drying device 7 is also activated to dry the outer contour of the valve plate 12 that has just been coated, in order to accelerate the curing and drying of the coating liquid and form a uniform and dense protective coating.

[0035] After coating is completed, the control drive cylinder 9 is activated, causing the liquid storage box to move backward along the slide rail 8, which in turn causes the coating roller 4 to disengage from the valve plate 12. Subsequently, the valve plate 12 is removed from the support roller 3 and transferred to the valve plate 12 stacking device for collection.

[0036] In subsequent operations, multiple valve plates 12 stacked on the stacking rod 11 are grouped together, the upper cover plate 13 is placed on top, and the nuts 14 are tightened to form an integral unit (such as...). Figure 5 and Figure 6 (As shown), the entire unit is then sent into the spray booth, where only the outer side is sprayed to effectively prevent paint from contaminating the upper and lower sealing surfaces of the valve plate 12.

[0037] The coating equipment of this utility model supports and drives the valve plate 12 to rotate by a synchronously rotating idler roller 3, and uses the coating roller 4 in the liquid storage box to coat the outer contour of the suspended and exposed valve plate 12. This enables fast and accurate coating of the outer contour of the valve plate 12 without contaminating the upper and lower sealing surfaces of the valve plate 12, ensuring the flatness and sealing performance of the valve plate 12, and greatly improving production efficiency and product qualification rate.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
