Description

Technical Field

[0001] This utility model relates to the field of coating device technology, and in particular to a coating device for corrosion-resistant right-angle fasteners. Background Technology

[0002] Right-angle couplers are key connecting components in many fields such as construction and machinery manufacturing. Their performance directly affects the stability and safety of the entire structure. In actual application environments, right-angle couplers are often exposed to complex and changeable climatic conditions and corrosive media, such as humid air at construction sites, rainwater containing chemicals, and corrosive gases in industrial production workshops. This makes right-angle couplers extremely susceptible to corrosion. Once corrosion occurs, it will not only reduce their mechanical strength and affect the reliability of the connection, but may also lead to a significant reduction in the service life of the entire structure, or even cause serious safety accidents.

[0003] To improve the corrosion resistance of right-angle fasteners, applying a coating to their surface is a widely used and effective method. Currently, most existing methods use spraying to coat right-angle fasteners. However, right-angle fasteners are irregularly shaped parts with many internal and external corners. This special structure makes it difficult to achieve uniform coating coverage during the spraying process. At internal corners, the coating thickness is often insufficient due to the limited spraying angle, failing to form an effective protective barrier. At external corners, the coating tends to accumulate too thickly, affecting not only the appearance but also potentially reducing the mechanical properties of the fastener.

[0004] Furthermore, the existing spraying process is not efficient in terms of the utilization rate of the coating material. A large amount of coating material fails to adhere accurately to the surface of the right-angle fastener during the spraying process and instead drifts into the surrounding environment, which not only wastes resources but also pollutes the surrounding environment. Utility Model Content

[0005] The main objective of this invention is to provide a coating device for corrosion-resistant right-angle fasteners, which can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A coating device for corrosion-resistant right-angle fasteners includes a liquid tank with an open top and a receiving box installed at the front end of the liquid tank. A conveying assembly is inclinedly arranged on the upper side of the inner cavity of the liquid tank, with the top of the conveying assembly facing the side close to the receiving box. A stirring assembly is rotatably arranged on the lower side of the inner cavity of the liquid tank, and a transmission assembly is arranged at the back end of the liquid tank.

[0008] Preferably, the conveying assembly includes a partition layer and a rotating rod. The partition layer is fixedly installed in the inner cavity of the liquid pool in an inclined manner. The top of the partition layer is located on the side close to the receiving box. A protective cover is fixedly installed at the top of the partition layer in an inclined manner.

[0009] Preferably, the middle part of the partition layer is concave arc-shaped, the outer surface of the rotating rod is fixedly installed with a conveying blade that is adapted to the middle part of the inner cavity of the partition layer, the downstream end of the rotating rod is fixedly connected with a universal joint, and multiple liquid drop grooves are equidistantly opened through the middle of the bottom end of the rotating rod.

[0010] Preferably, the stirring assembly includes two stirring shafts, which are symmetrically rotated and installed on both sides of the inner cavity of the liquid tank away from the center. Multiple fan blades are fixedly installed in a common annular array on the outer surface of the two stirring shafts.

[0011] Preferably, the transmission assembly includes a mounting base and two gears. The mounting base is fixedly installed in the middle of the back end of the liquid tank, and a motor is fixedly installed on the top of the mounting base. The two gears are respectively coaxially and fixedly connected to the rear side of the outer surface of the two stirring shafts.

[0012] Preferably, a connecting rod is fixedly connected to the output shaft of the motor via a coupling, and the other end of the connecting rod is connected to the end of the universal joint away from the rotating rod. A gear pair is coaxially fixedly connected to the outer surface of the connecting rod, and the gear pair is connected to the two gears respectively via two chain drives.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model uses an immersion method to coat right-angle fasteners. Compared with the traditional spray coating method, the immersion method can make the coating uniform, improve the corrosion resistance, increase material utilization, be environmentally friendly, reduce costs, and is simple to operate and easy to promote. At the same time, by setting up a conveying component to flip the right-angle fasteners immersed in the conveying liquid pool, the right-angle fasteners can be uniformly coated and then automatically unloaded. This achieves two goals at once and is more practical.

[0015] 2. This utility model uses a stirring component to agitate the liquid coating material in the liquid pool, thereby preventing sedimentation and stratification of the liquid coating material and enhancing the uniformity of the coating material. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-5 As shown, a coating device for corrosion-resistant right-angle fasteners includes a liquid tank 1 with an open top. A receiving box 2 is installed at the front end of the liquid tank 1. A conveying assembly 3 is inclinedly arranged on the upper side of the inner cavity of the liquid tank 1, with the top of the conveying assembly 3 located on the side close to the receiving box 2. A stirring assembly 4 is rotatably arranged on the lower side of the inner cavity of the liquid tank 1, and a transmission assembly 5 is arranged at the back end of the liquid tank 1.

[0024] This solution uses an immersion method to coat right-angle fasteners. After the coating liquid is poured into liquid tank 1, the highest water level of the liquid coating should not be higher than two-thirds of the height of the inner cavity of liquid tank 1.

[0025] In practical use, the transmission component 5 drives the inclined conveying component 3 within the liquid tank 1 to flip the right-angle fasteners immersed in the plating solution within the liquid tank 1. This allows the right-angle fasteners to be evenly platingd and then automatically discharged into the receiving box 2 for centralized further processing. Simultaneously, the transmission component 5 drives the conveying component 3... The stirring component 4 agitates the liquid coating material in the liquid pool 1 to prevent sedimentation and stratification of the liquid coating material.

[0026] Specifically, the conveying assembly 3 includes a partition layer 31 and a rotating rod 32. The partition layer 31 is fixedly installed in the inner cavity of the liquid pool 1 in an inclined manner. The top of the partition layer 31 is located on the side close to the receiving box 2. A protective cover 34 is fixedly installed at the top of the partition layer 31 in an inclined manner.

[0027] The middle part of the partition layer 31 is concave arc-shaped. The outer surface of the rotating rod 32 is fixedly installed with a conveying blade 33 that is compatible with the middle part of the inner cavity of the partition layer 31. The downstream end of the rotating rod 32 is fixedly connected with a universal joint 35. Multiple liquid drop grooves 36 are equidistantly opened in the middle of the bottom end of the rotating rod 32.

[0028] After the right-angle fastener is placed into the liquid pool 1, the protective cover 34 installed on the partition layer 31 prevents the right-angle fastener from hitting the conveyor blade 33 when it falls. The right-angle fastener automatically slides down to the bottom of the slope of the partition layer 31 through the inclined surface of the partition layer 31 or the protective cover 34. The transmission component 5 drives the rotating rod 32 to rotate and transport the right-angle fastener. When the right-angle fastener is rotated and transported, it can come into contact with the liquid coating material in the liquid pool 1 without dead angles. In this way, the coating material is evenly distributed on the right-angle fastener. During the upward transport of the right-angle material, the liquid coating material flows back into the liquid pool 1 through the drop trough 36 at the bottom of the rotating rod 32. After the right-angle fastener is transported to the uppermost position, it falls into the receiving box 2 for centralized processing.

[0029] Furthermore, the stirring assembly 4 includes two stirring shafts 41, which are symmetrically rotated and installed on both sides of the inner cavity of the liquid tank 1 away from the center. Multiple fan blades 42 are fixedly installed in a common annular array on the outer surface of the two stirring shafts 41.

[0030] When the transmission component 5 drives the conveying component 3, it drives the two stirring shafts 41 to rotate. During the rotation of the two stirring shafts 41, they jointly drive the ring array of fan blades 42 installed on their outer surfaces to stir the liquid coating material in the liquid pool 1, so as to avoid the precipitation of the liquid coating material.

[0031] Furthermore, the transmission assembly 5 includes a mounting base 51 and two gears 55. The mounting base 51 is fixedly installed in the middle of the back end of the liquid tank 1, and a motor 52 is fixedly installed on the top of the mounting base 51. The two gears 55 are coaxially and fixedly connected to the rear side of the outer surface of the two stirring shafts 41 respectively.

[0032] A connecting rod 53 is fixedly connected to the output shaft of the motor 52 via a coupling. The other end of the connecting rod 53 is connected to the end of the universal joint 35 away from the rotating rod 32. A gear pair 54 is coaxially fixedly connected to the outer surface of the connecting rod 53. The gear pair 54 and two gears 55 are respectively connected to the transmission of two chains 56.

[0033] A brake motor 52 drives a connecting rod 53 and a universal joint 35 to rotate a rotating rod 32, allowing the conveying blades 33 on the rotating rod 32 to rotate and convey materials. At the same time, a gear pair 54 is installed on the outer surface of the connecting rod 53. Two gears 55 are coaxially and fixedly connected to two stirring shafts 41 respectively. Two chains 56 are connected between the two gears 55 and the gear pair 54. Thus, when the motor 52 rotates, it drives the two stirring shafts 41 to rotate together to stir the liquid coating material in the liquid pool 1.

[0034] It should be noted that the specific installation method of the motor 52, the circuit connection method, and the control method used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
