Description

Technical Field

[0001] This utility model relates to the field of electrophoresis processing equipment technology, and in particular to a hanging rail for an electrophoresis processing production line. Background Technology

[0002] Electrophoretic coating lines are key equipment in modern industry for metal surface treatment. They form a protective film on metal surfaces using electrochemical methods to enhance corrosion resistance and aesthetics. These lines typically include multiple interconnected stations such as pretreatment, electrophoretic coating, spray cleaning, and drying, ensuring continuous and efficient production. The entire system is designed for automation, minimizing manual intervention and improving product quality consistency. To support these complex operations, the line is equipped with a precision-designed overhead rail system that smoothly transfers workpieces from one station to the next. This system must not only withstand the weight of the workpieces but also maintain stability and reliability during long-term operation.

[0003] However, in practical applications, the overhead conveyor rails of electrophoresis processing lines are constantly exposed to a humid environment, especially after the spray cleaning process, where moisture inevitably comes into contact with the interior of the rails. This moisture easily causes the drive chain inside the rails to rust. As the usage time increases, this rusting gradually worsens, leading to a series of problems. For example, a rusted drive chain can cause significant noise during the operation of the overhead conveyor rails, affecting the working environment; more seriously, if it is not detected and addressed in time, the drive chain may break due to excessive wear, severely impacting the production line. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hanging rail for an electrophoresis processing production line, which solves the technical problem that the transmission chain in the hanging rail of existing electrophoresis processing production lines is prone to contact with water, leading to corrosion.

[0005] According to an embodiment of the present invention, a hanging rail for an electrophoresis processing production line includes a profile and a transmission chain disposed within the profile. The bottom of the profile is provided with an opening, and connecting mechanisms are evenly distributed on the transmission chain. The connecting mechanisms pass through the opening and are connected to a hanger.

[0006] The connecting mechanism includes two rollers and a lower connecting piece disposed between the two rollers. An upper connecting piece for connecting the transmission chain is provided on the outer side of the two rollers. The rollers are disposed on the inner side of the profile and located below the transmission chain. A stop block is provided at the opening of the lower connecting piece. A hanger is connected to the bottom of the lower connecting piece.

[0007] The technical principle of this utility model is as follows: During use, the presence of a stop block covers the opening of the profile through which the lower connecting piece passes, preventing water from entering; at the same time, the evenly distributed rollers support the transmission chain, placing it on the inner side of the profile furthest from the opening, thus preventing it from contacting water. Furthermore, the use of rollers transforms the sliding friction between the transmission chain and the profile into rolling friction between the rollers, the transmission chain, and the profile, which helps to improve the service life of the profile and the transmission chain.

[0008] Compared with the prior art, this utility model has the following beneficial effects: by using a connecting mechanism with rollers and a lower connecting piece with a stop, it solves the technical problem that the transmission chain in the existing electrophoresis processing production line is easily exposed to water and thus corrodes, thereby significantly improving the service life of the transmission chain and profile.

[0009] Furthermore, the bottom of the profile is provided with inclined surfaces on both sides of the opening, and the inclined surfaces are inclined close to each other.

[0010] Furthermore, the included angle between the two inclined surfaces is 145°-125°.

[0011] Furthermore, the opening is provided with a rubber edge, which is an extension of the inclined surface. The rubber edge is in close contact with both sides of the lower connecting piece, and the stop block is located on the upper side of the rubber edge.

[0012] Furthermore, the stop block covers the bottom of the profile, and the bottom of the stop block is symmetrically provided with conical surfaces on both sides.

[0013] Furthermore, the included angle between the two conical surfaces is 60°-90°.

[0014] Furthermore, the profile has rubber edges on both sides at the bottom, and the rubber edges are attached to the stop block.

[0015] Furthermore, the profile has grooves on both sides of the opening, and the two rollers have protrusions corresponding to the grooves. The protrusions are inserted into the grooves, and there is a gap between the protrusions and the grooves.

[0016] Furthermore, the raised cylindrical surface is provided with a frosted texture.

[0017] Furthermore, a sealing edge is provided inside the profile near the opening, the sealing edge is in close contact with the lower connecting piece, and the stop block is located below the sealing edge. Attached Figure Description

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figure 1-2 The suspended rail of the electrophoresis processing line shown includes a profile 1 and a transmission chain 2 installed inside the profile 1. The bottom of the profile 1 is provided with an opening 11. Connecting mechanisms 3 are evenly distributed on the transmission chain 2. The connecting mechanisms 3 pass through the opening 11 and are connected to the hangers 4. The beginning and end of the transmission chain 2 are connected and are driven by a drive device to form a cyclic transmission structure.

[0026] The specific connecting mechanism 3 includes two rollers 31 and a lower connecting piece 32 disposed between the two rollers 31. An upper connecting piece 33 for connecting the transmission chain 2 is provided on the outer side of the two rollers 31. That is, the two rollers 31, the two upper connecting pieces 33 and the lower connecting piece 32 are connected by a roller shaft. The rollers 31 are disposed on the inner side of the profile 1 and located on the lower side of the transmission chain 2. The lower connecting piece 32 is provided with a stop block 321 at the opening 11. The bottom of the lower connecting piece 32 is connected to a hanger 4. The hanger 4 is used to suspend the parts that need to be electrophoretically processed.

[0027] Because there are two sides of the baffle 321, the baffle 321 can block the opening 11 and prevent water from entering the inside of the profile 1.

[0028] like Figure 2 As shown, the bottom of the profile 1 is provided with inclined surfaces 12 on both sides of the opening 11. The inclined surfaces 12 are close to each other and inclined. Specifically, the included angle between the two inclined surfaces 12 is 145°-125°, which makes it easy for the water adsorbed at the bottom of the profile 1 to converge to both sides and eventually drip down.

[0029] like Figure 2As shown, a rubber edge 13 is provided at the opening 11. The rubber edge 13 is an extension of the inclined surface 12. The rubber edge 13 is close to both sides of the lower connecting piece 32. The stop block 321 is located on the upper side of the rubber edge 13. That is, the rubber edge 13 and the stop block 321 form a maze structure to prevent moisture from entering the interior of the profile 1 from the gaps and contaminating the transmission chain 2.

[0030] Example 2

[0031] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the bottom of the profile 1 is a flat structure, the baffle 321 covers the bottom of the profile 1, and the baffle 321 has symmetrical conical surfaces 3211 on both sides of the bottom. The included angle between the two conical surfaces 3211 is 60°-90°, which makes it easier for water to collect and slide off compared to embodiment 1. Specifically, the bottom of both sides of the profile 1 is provided with rubber edges 13, which are attached to the baffle 321 to prevent water from entering the gap between the baffle 321 and the profile 1.

[0032] Compared to Example 1, this embodiment reduces the thickness of the bottom of profile 1, which helps to reduce the processing difficulty of profile 1.

[0033] Example 3

[0034] like Figure 4 As shown, the difference between this embodiment and embodiment 2 is that: the profile 1 has grooves 14 on both sides of the opening 11, and the two rollers 31 have protrusions 311 corresponding to the grooves 14. The protrusions 311 are inserted into the grooves 14, and there is a gap between the protrusions 311 and the grooves. The gap is used to store lubricating oil. Specifically, the cylindrical surface of the protrusions 311 has a frosted texture, which can easily drive the rollers to the transmission chain at the top of the rollers 31, thereby playing a lubricating role, reducing the noise of the transmission chain 2 and extending its service life.

[0035] like Figure 4 As shown, a sealing edge 15 is provided inside the profile 1 near the opening 11. The sealing edge 15 is in close contact with the lower connecting piece 32. The stop block 321 is located below the sealing edge 15 to prevent lubricating oil from flowing out along the lower connecting piece 32.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
