These are done for simplicity and clarity of description and are not intended to show any particular relationship between the examples discussed.

[0034] As Figures 1-12 An engineering machinery intensive spraying conveying system, comprising a carrier vehicle 10 and a first transfer conveying area 1, a first working conveying area 2, a second transfer conveying area 3, and a second working conveying area 4 arranged in sequence from front to back, a paint spraying room 5 and a loading and unloading area 6 arranged at intervals left and right on the first working conveying area 2, a first drying oven 7 and a second drying oven 8 arranged at intervals left and right on the second working conveying area 4, the first transfer conveying area 1 is used to convey the carrier vehicle 10 on the loading and unloading area 6 into the paint spraying room 5, the second transfer conveying area 3 is used to convey the carrier vehicle 10 in the paint spraying room 5 into the first drying oven 7 or the second drying oven 8, and the carrier vehicle 10 in the first drying oven 7 and the second drying oven 8 is conveyed onto the loading and unloading area 6.

[0035] According to the above structure, the first transfer conveying area 1 can quickly and accurately convey the carrier vehicle 10 of the loading and unloading area 6 to the paint spraying room 5, avoiding the time loss of manual transfer; the second transfer conveying area 3 supports the flexible selection of the carrier vehicle 10 after spraying between the first drying oven 7 and the second drying oven 8, selects the drying path according to the process requirements of the workpiece, and at the same time can directly return the dried workpiece to the loading and unloading area 6, forming a closed loop process of "loading and unloading → spraying → drying → loading and unloading", greatly shortening the production cycle.

[0036] The first working conveying area 2 and the second working conveying area 4 can operate simultaneously, and the spraying and drying processes are synchronized to realize an efficient production mode of "spraying and drying simultaneously", which is more than 50% more efficient than the traditional single process sequential execution mode.

[0037] The paint spraying room 5 and the loading and unloading area 6 are arranged at intervals left and right on the first working conveying area 2, and the two drying ovens 7 and 8 are arranged at intervals left and right on the second working conveying area 4, forming a compact "left and right parallel + front and back series" layout, which can save more than 30% of the factory space compared with the traditional dispersed layout; and the parallel double drying oven design can simultaneously process workpieces with different process requirements, avoiding the production bottleneck of a single drying oven, and further improving the space utilization.

[0038] The second transfer zone 4 can be flexibly allocated to different drying furnaces according to the workpiece type (such as different materials and coating thicknesses), and can support differentiated process parameters (such as temperature and time) to meet the mixed production of multiple varieties of workpieces.

[0039] The double drying furnaces can be independently started and stopped according to the workpiece requirements, thereby avoiding the energy waste of the traditional single drying furnace.

[0040] Referring to Figure 3 As shown, the carrier 10 is a conventional existing configuration, which includes a rectangular frame 201, support feet 202 provided at the lower sides of the four corners of the rectangular frame 201 and provided with rollers, and a plurality of support beams 203 spaced apart in the front-rear direction on the rectangular frame 201.

[0044] The one-way stop mechanism and the blocking positioning mechanism are installed at appropriate positions on the first transverse track groups 21; after the carrier 10 enters the working zone, it first contacts the one-way stop mechanism, which prevents the carrier 10 from retreating by virtue of the one-way stop feature; when the carrier 10 continues to move forward to the designated position, the blocking positioning mechanism is activated to firmly fix the carrier 10 by mechanical blocking, thereby ensuring that the carrier 10 remains stationary during the paint spraying operation.
