[0072] The conveying trolley with the mechanical rotating disc of the present application is provided with a gear on the rotating disc, and a first fixture connected to the rotating disc above the rotating disc. The gear is provided so that the operator can realize the mechanical driving of the rotating disc by setting a blocking piece corresponding to the gear on one side of the conveying line.

[0073] The first fixture is used for mounting the workpiece or connecting other fixtures of the workpiece.

[0074] In operation, the conveying trolley is placed on the conveying line and can move along the conveying line under the driving of the chain, connecting rope or the like.

[0075] When the conveying trolley moves to the blocking piece, the blocking piece contacts the gear.

[0076] To realize the reverse rotation of the rotating disc, another blocking piece can be arranged on the other side of the conveying line.

[0077] Under the driving of the blocking piece, the conveying trolley with the mechanical rotating disc does not need to be separately provided with a driving motor to realize the driving of the rotating disc, thereby simplifying the overall structure of the conveying trolley, reducing the production cost and prolonging the service life.

[0078] The blocking piece for driving the rotating disc can have a certain elasticity and can be made of plastic, steel plate or the like. To make the rotating disc rotate by a certain angle, the operator can use a blocking piece with a corresponding length to drive the rotating disc, and the specific length is subject to the actual requirement.

[0079] To reduce the impact between the blocking piece and the gear, the blocking piece can be an arc-shaped blocking piece.

[0080] To facilitate the installation of the rotating disc, in the present embodiment, the surface of the bottom disc is provided with a connecting column 5, the bottom end of the connecting column is fixedly arranged on the surface of the bottom disc, and the rotating disc is rotatably arranged on the connecting column.

[0081] Specifically, a connecting cylinder 6 is arranged below the rotating disc, the connecting cylinder includes an upper cylinder body 7 and a lower cylinder body 8, and the gear is arranged between the upper cylinder body and the lower cylinder body.

[0082] Specifically, the bottom surface of the upper cylinder and the top surface of the lower cylinder are both provided with annular positioning rims 9, and the disc of the gear is sleeved on the annular positioning rims, and the upper cylinder presses the disc of the gear against the top surface of the lower cylinder.

[0083] The upper and lower ends of the connecting cylinder are connected with the connecting column through bearings 10 respectively.

[0084] In order to facilitate the installation of the first device, the middle part of the rotating disc is provided with an installation cylinder 11, the bottom end of the installation cylinder is fixed on the rotating disc, the middle part of the first device is provided with a plug rod 12, the bottom end of the plug rod is arranged in the installation cylinder, and the plug rod can be fixed with the installation cylinder through interference fit or through screws.

[0085] In order to realize the positioning of the rotating disc, one side of the rotating disc is provided with a first positioning assembly, the first positioning assembly comprises a first guide rail 13 arranged on the surface of the bottom disc, a first sliding block 14 matched with the first guide rail, a first connecting block 15 fixedly connected with the first sliding block, and a clamping column 16 arranged at one end of the first connecting block close to the gear, a driving plate 17 connected with the rotating disc is further arranged above the bottom disc, a linkage plate 18 is arranged between the driving plate and the first clamping column, one end of the linkage plate is hinged to the first connecting block, and the other end of the linkage plate is hinged to the driving plate.

[0086] In the embodiment, the driving plate is located below the connecting cylinder, the driving plate and the connecting column are connected through bearings, and the two ends of the driving plate protrude from the circumferential surface of the connecting cylinder.

[0087] In a normal state, the top end of the clamping column is located in the gear slot, so as to clamp the gear and prevent the gear from rotating. When the blocking piece drives the rotating disc to rotate, the driving plate rotates together with the rotating disc. With the rotation of the driving plate, the driving plate drives the first connecting block to move away from the rotating disc through the linkage plate. At this time, the clamping column originally located in the gear slot is gradually moved out of the gear slot, so that the gear can drive the rotating disc to rotate to a predetermined angle.

[0088] When the rotating disc moves reversely under the driving of the blocking piece, the driving plate reversely rotates under the driving of the rotating disc, so as to drive the first connecting block to the original position through the linkage plate, and the top end of the clamping column enters the gear slot again, thereby preventing the rotating disc from rotating when the conveying trolley moves.

[0089] The first connecting block is a T-shaped block, the bottom end of the clamping column is fixedly arranged on the front end of the T-shaped block, and the end of the linkage plate is hinged to the hinge pin on the side of the T-shaped block.

More equipment is needed to meet the requirements, and a large enough space between workpieces is needed to ensure that the two end faces of the workpiece are processed, which affects the production efficiency.

[0129] The workpiece can realize 6 faces at a time under the condition of rotating spraying, and the specific steps of spraying are as follows:
