Description

TECHNICAL FIELD

[0001] The utility model relates to a ground chain conveying line especially a ground chain dustproof structure for coating production line. BACKGROUND

[0002] The ground chain conveying coating line is an advanced automatic production line, which is mainly used for coating and conveying in automobile, household appliance and other industries, and is mainly composed of a conveying chain, a track and a jig. For example, the Chinese patent with the authorization announcement number CN201735480U and the authorization announcement date of February 9, 2011 discloses an automatic coating equipment special for aluminum alloy wheels, which comprises a ground chain, a drying furnace and a coating device. The ground chain is driven by a driving motor and passes through the drying furnace. The coating device comprises at least two spray guns arranged along the ground chain before the drying furnace. The spray angle of each spray gun is different. The driving motor and the coating device are controlled by an automatic controller. A plurality of vertical driving shafts for placing the wheels are installed on the ground chain. The ground chain in the coating equipment runs in the track. The chain will bring in dust (paint powder) when running. The dust will solidify when passing through the drying channel, which will cause the wheels to be stuck and increase the resistance of the chain. The track is prone to wear. SUMMARY

[0003] The utility model discloses a ground chain dustproof structure for coating production line which can effectively prevent dust from entering the track to solve the problem that the ground chain in the prior art is prone to bringing in dust when running, causing the wheels to be stuck and the track to be worn.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a ground chain dustproof structure for coating production line, comprising a ground chain, a track and a rotary jig, the track has two opposite tracks, and a walking wheel U-shaped groove is formed on the opposite surfaces of the track. A side stop edge is arranged on the upper side of the walking wheel U-shaped groove. The gap between the opposite side stop edges forms a guide wheel groove. A dustproof cover plate is arranged above the guide wheel groove. The ground chain is arranged between the tracks. Walking wheels are arranged on the two sides of the ground chain and are in rolling connection with the walking wheel U-shaped groove. Guide wheels are arranged on the upper side of the ground chain and are in rolling connection with the guide wheel groove. A fixed plate is fixed to the lower side of the ground chain. The rotary jig is arranged outside the track and is fixedly connected with the fixed plate. The utility model improves the ground chain conveying structure. The dustproof cover plate is arranged above the opening (i.e. the guide wheel groove) between the tracks without affecting the running of the ground chain. At the same time, the rotary jig is arranged on the side surface of the track. The dustproof cover plate can effectively prevent dust from entering the track through the guide wheel groove, thereby effectively solving the problem that the walking wheels and the guide wheels are prone to being stuck. The structure is simple and ingenious. The rotary jig is a conventional structure in the field.

[0005] Preferably, a guide rail is fixed below the track, and a guide wheel is fixed to the lower end of the fixing plate, with the guide wheel engaging with the guide rail in a rolling manner. The cooperation between the guide rail and the guide wheel improves operational stability.

[0006] Preferably, an oil receiving tray is fixed below the rail.

[0007] Preferably, the fixed plate is provided with an L-shaped connecting plate, and the rotating fixture is fixedly connected to the L-shaped connecting plate.

[0008] Preferably, the rotating fixture and the L-shaped connecting plate are fixedly connected by bolts. The bolted connection ensures a secure connection and facilitates easy assembly and disassembly.

[0009] Preferably, the L-shaped connecting plate is provided with a reinforcing plate.

[0010] Preferably, a support side baffle is provided on the outer side of the track, and the upper end of the support side baffle is fixedly connected to a dust cover.

[0011] Therefore, this utility model has the following beneficial effects: the ground chain conveying structure has been improved, a dustproof cover plate is set above the opening between the tracks (i.e., the guide wheel groove), and the rotating fixture is set on the side of the track. Without affecting the operation of the ground chain, it can effectively prevent dust from entering the track through the guide wheel groove, which would cause the traveling wheel and guide wheel to jam easily.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 , Figure 2The dustproof structure for a ground chain in a painting production line, as shown, includes a ground chain 1, a track 2, and a rotating fixture 3. The track has two tracks arranged opposite each other. U-shaped grooves 4 for traveling wheels are recessed on the opposite surfaces of the tracks. Side guards 5 are provided on the upper side of the U-shaped grooves of the traveling wheels. A guide wheel groove 6 is formed by the gap between the opposite side guards. A dustproof cover 7 is provided above the guide wheel groove. Supporting side guards 16 are fixed to the outer side of the tracks, with the upper end of the supporting side guards fixedly connected to the dustproof cover. The ground chain is positioned between the tracks, and the ground chain has corresponding support grooves on both sides. The walking wheel 8 has a U-shaped groove for rolling engagement. A guide wheel 9 is provided on the upper side of the ground chain for rolling engagement with the guide wheel groove. A fixed plate 10 is fixed on the lower side of the ground chain. An L-shaped connecting plate 14 is provided on the fixed plate. A reinforcing plate 15 is provided on the L-shaped connecting plate. The rotating fixture is fixedly connected to the L-shaped connecting plate by bolts. The rotating fixture is located outside the track and fixedly connected to the fixed plate. A rail 11 is fixed below the track. A rail wheel 12 is fixed at the lower end of the fixed plate. The rail wheel and the rail are in rolling engagement. An oil receiving tray 13 is fixed below the rail.

[0017] The working principle of this utility model is as follows: the ground chain drives the walking wheel, guide wheel and support wheel to move along the ground chain conveying direction. At the same time, the ground chain drives the rotating fixture to move along the ground chain conveying direction through the fixed plate and L-shaped connecting plate. When the ground chain passes through the powder spraying chamber, the powder cannot enter the track due to the blocking effect of the dust cover.

[0018] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
