Description

Technical Field

[0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a conveyor chain device of an automatic spraying line and an automatic spraying line. Background Art

[0002] During the processing of fire extinguisher cylinders, the surface of the cylinders needs to be phosphated first and then painted. The surface of the cylinder after phosphating has a phosphating film, which is used as a primer before painting to improve the adhesion and corrosion resistance of the coating layer. At present, the phosphating and painting treatments in this processing process need to be carried out on an automated spray production line.

[0003] For example, the Chinese utility model patent application number CN201220621078.1 discloses a steel cylinder hanging fixture for an automated spray line and an automated spray line, wherein the steel cylinder hanging fixture comprises a support plate, a hook fixed on the support plate, and a columnar sleeve mounted on the support plate for placing the steel cylinder; the automated spray line comprises a conveyor chain device, a steel cylinder hanging fixture suspended on the conveyor chain device, and a spray device for performing phosphating treatment on the steel cylinder on the fixture.

[0004] The disadvantage of the automatic spraying line is that the conveyor chain device is arranged above the production line, and the steel cylinder hanging tool is hung on the conveyor chain device. Since the conveyor chain device is located at a high position, it is inconvenient to install the steel cylinder hanging tool and install the steel cylinder. Summary of the invention

[0005] The invention aims to provide a conveyor chain device and an automated spraying line which are convenient for installing steel cylinder fixing tooling and for installing an automated spraying line of steel cylinders.

[0006] To achieve the above-mentioned object of the invention, the technical solution of the present invention is as follows:

[0007] A conveyor chain device for an automated spraying line comprises at least two conveyor chains which are synchronously operated on the bottom side of the automated spraying line and are arranged in parallel, wherein two ends of the conveyor chains are respectively fixed and wound on a first winding drum and a second winding drum, and the first winding drum and the second winding drum are respectively driven by respective driving mechanisms to rotate.

[0008] The present invention sets the conveyor chain device at the bottom side of the automated spray line, so that the staff can perform operations such as installing the steel cylinder fixing tooling or installing the steel cylinder while standing on the ground, which is convenient and quick; and after being set at the bottom side, the operation of the conveyor chain device will not cause any safety hazards to the surrounding people and things. After being set at the bottom side, it is necessary to install the steel cylinder fixing tooling above the conveyor chain device, so the conveyor chain device cannot run in a ring shape and can only reciprocate in the horizontal direction. Therefore, the present invention uses a first winding drum and a second winding drum, each with a driving mechanism, to install the conveyor chain so as to realize the reciprocating movement of the conveyor chain.

[0009] In the conveyor chain device of the above-mentioned automatic spraying line, a triangular shaped synchronization base is arranged across two adjacent conveyor chains, and the synchronization base helps to ensure that the connected conveyor chains run synchronously.

[0010] In the conveyor chain device of the above-mentioned automatic spraying line, the synchronization base includes two first fixed seats installed on one of the conveyor chains and a second fixed seat installed on the other conveyor chain, and connecting rods are provided between the second fixed seat and the two first fixed seats.

[0011] The conveyor chain is continuously wound out or rolled up between the first winding drum and the second winding drum, so the amount of the conveyor chain wound on the first winding drum and the second winding drum is different, which will cause the conveyor chain to not be kept on the same horizontal line, affecting the operational stability of the cylinder fixing tool. Therefore, in the conveyor chain device of the above-mentioned automatic spraying line, the conveyor chain extension sides of the first winding drum and the second winding drum are both provided with a leveler to keep the conveyor chain between the first winding drum and the second winding drum horizontal.

[0012] In the conveying chain device of the above-mentioned automated spraying line, the outer periphery of the first winding drum or the second winding drum is provided with retaining rings located at both ends of the first winding drum or the second winding drum and used to limit the conveying chain on the first winding drum or the second winding drum, and the aligner is arranged between the two retaining rings, and the aligner has a flared portion for the conveying chain to pass through, and a aligning opening for the conveying chain to pass through, and all the aligning openings are at the same height.

[0013] In the above-mentioned conveyor chain device of the automatic spraying line, the positioner has an arc-shaped guide surface close to the position opening, which helps to guide the conveyor chain to pass into the position opening.

[0014] In the conveyor chain device of the above-mentioned automatic spraying line, a plurality of spacer rings are evenly arranged axially on the outer periphery of the first winding drum, and winding spaces corresponding to the conveyor chains are formed between the spacer rings and the corresponding retaining rings and between adjacent spacer rings. How can we avoid the adjacent conveyor chains from getting tangled with each other and affecting normal operation?

[0015] An automated spraying line comprises the conveyor chain device of the present invention, wherein the conveyor chain device is provided with a steel cylinder fixing tool.

[0016] In the above-mentioned automated spraying line, the steel cylinder fixing fixture comprises a support base, and the support base is fixedly mounted on the synchronization base.

[0017] In the above-mentioned automated spraying line, the steel cylinder fixing fixtures are arranged in groups, and the steel cylinder fixing fixtures of different groups are arranged at intervals on the conveying chain device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention sets the conveyor chain device at the bottom side of the automated spray line, so that the staff can perform operations such as installing the steel cylinder fixing tooling or installing the steel cylinder while standing on the ground, which is convenient and quick; and after being set at the bottom side, the operation of the conveyor chain device will not cause any safety hazards to the surrounding people and things. After being set at the bottom side, it is necessary to install the steel cylinder fixing tooling above the conveyor chain device, so the conveyor chain device cannot run in a ring shape and can only reciprocate in the horizontal direction. Therefore, the present invention uses a first winding drum and a second winding drum, each with a driving mechanism, to install the conveyor chain so as to realize the reciprocating movement of the conveyor chain.
