Description

Technical Field

[0001] The present invention relates to the technical field of spraying and conveying systems, and in particular to an intensive spraying and conveying system for engineering machinery. Background Art

[0002] In the field of construction machinery manufacturing, the spraying process is a key step, involving processes such as painting and drying workpieces. Traditional spray conveying systems typically adopt a single linear layout, with each process (such as loading and unloading, painting, and drying) set up independently and relying on manual or simple conveying equipment to connect them. This has the following significant drawbacks: 1. The connection between processes is poor, and the carrier (workpiece carrier) must be manually transferred multiple times, resulting in long waiting times, the inability to achieve continuous operation, and low production efficiency. 2. The traditional system layout is fragmented, with each functional area (such as the paint booth and drying oven) occupying its own space. Especially for large construction machinery workpieces, multiple sets of independent equipment are required, resulting in wasted factory space and insufficient space utilization. 3. A single drying path is difficult to adapt to the process requirements of different workpieces (such as drying temperature and time differences). The adjustment cycle is long during production changeovers, making it difficult to meet diverse production needs and lacking flexibility. Summary of the Invention

[0031] The following detailed description provides various embodiments or examples for implementing the present invention. Of course, these are merely examples or embodiments and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. Such repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the different embodiments and / or configurations discussed.

[0032] like Figures 1-12 The shown embodiment shows an intensive spraying and conveying system for engineering machinery, comprising a carrier 10 and a first ferry conveying area 1, a first working conveying area 2, a second ferry 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 on the left and right of the first working conveying area 2, and a first drying furnace 7 and a second drying furnace 8 arranged on the left and right of the second working conveying area 4. The first ferry conveying area 1 is used to transport the carrier 10 on the loading and unloading area 6 to the paint spraying room 5, and the second ferry conveying area 3 is used to transport the carrier 10 in the paint spraying room 5 to the first drying furnace 7 or the second drying furnace 8, and to transport the carrier 10 in the first drying furnace 7 and the second drying furnace 8 to the loading and unloading area 6.

[0033] According to the above structure, the first ferry conveying area 1 can quickly and accurately transport the carrier 10 from the loading and unloading area 6 to the paint room 5, avoiding the time loss of manual transfer; the second ferry conveying area 3 supports the carrier 10 after painting to flexibly choose between the first drying furnace 7 and the second drying furnace 8, and select the drying path according to the workpiece process requirements. At the same time, the dried workpiece can be directly returned to the loading and unloading area 6, forming a closed-loop process of "loading and unloading → painting → drying → loading and unloading", which greatly shortens the production cycle.

[0034] The first working conveying area 2 and the second working conveying area 4 can operate simultaneously, and the painting and drying processes are carried out simultaneously, realizing an efficient production mode of "spraying and drying at the same time", which is more than 50% more efficient than the traditional method of executing single processes sequentially.

[0035] The paint booth 5 and the loading and unloading area 6 are spaced apart in the first work conveying area 2, and the two drying ovens 7 and 8 are spaced apart in the second work conveying area 4, forming a compact "left-right parallel + front-back series" layout. Compared with the traditional decentralized layout, it can save more than 30% of factory space. Moreover, the parallel dual drying oven design can simultaneously process workpieces with different process requirements, avoiding the production capacity bottleneck of a single drying oven and further improving space utilization.

[0036] The second ferry conveying area 4 can be flexibly allocated to different drying ovens according to the type of workpiece (such as different materials, coating thickness), supports differentiated process parameters (such as temperature, time), and meets the mixed flow production of multiple varieties of workpieces.

[0037] The dual drying furnaces can be started and stopped independently according to the workpiece demand, avoiding the energy waste of the traditional single drying furnace.

[0038] See also Figure 3 As shown, the carrier 10 is a conventional configuration, which includes a rectangular frame 201, support legs 202 with rollers provided at the lower sides of the four corners of the rectangular frame 201, and a plurality of support beams 203 spaced apart on the front and rear of the rectangular frame 201.

[0039] See also Figure 1 、 Figure 2 、 Figure 4 As shown, the first working conveying area 2 and the second working conveying area 4 have the same structure, wherein both include two first transverse rail groups 21 spaced apart from each other and extending in the front-to-back direction.

[0040] Two sets of first transverse track groups 21 of the same specifications and materials are laid at intervals on the ground of the first working conveying area 2 and the second working conveying area 4. The track groups are made of high-strength steel and the surface is treated for wear resistance. The track spacing is precisely designed according to the size of the transport vehicle to ensure that the transport vehicle 10 can slide stably on the track. The track groups of the two working areas have interchangeable parts to facilitate subsequent maintenance and upgrades.

[0041] See also Figure 4-Figure 6 As shown, one-way anti-return mechanisms and blocking positioning mechanisms are provided on the two first transverse rail groups 21 of the first working conveying area 2, and the transport vehicle 10 can be limited and fixed between the one-way anti-return mechanism and the first blocking positioning mechanism.

[0042] On the first transverse rail group 21, a one-way anti-return mechanism and a blocking positioning mechanism are installed at appropriate positions; after the carrier 10 enters the working area, it first contacts the one-way anti-return mechanism, and uses its one-way anti-return feature to prevent the carrier 10 from retreating; when the carrier 10 continues to move forward to the designated position, the blocking positioning mechanism is activated, and the carrier 10 is firmly fixed by mechanical blocking to ensure that it remains stationary during the painting operation.

[0043] See also Figure 5 As shown, the one-way anti-retreat mechanism includes a anti-retreat mounting plate 31 provided on the first transverse rail group 21, a anti-retreat seat 32 is provided on the anti-retreat mounting plate 31, and a anti-retreat block 33 is hinged on the anti-retreat seat 32. The two ends of the anti-retreat block 33 have different weights, so that one end of the anti-retreat block 33 hangs down and rests on the anti-retreat seat 32, and the other end remains tilted upward.

[0044] The one-way anti-recoil mechanism adopts a anti-recoil block 33 design with different weights at both ends, and uses the principle of gravity to achieve the one-way anti-recoil function. The structure is simple and reliable, does not require a complex power drive device, reduces equipment cost and failure rate, and is easy to maintain; specifically, a anti-recoil mounting plate 31 is installed on the first transverse rail group 21, and a anti-recoil seat 32 is fixed on the anti-recoil mounting plate 31, and the anti-recoil block 33 is hinged to the anti-recoil seat 32; due to the weight difference at both ends of the anti-recoil block 33, one end naturally droops and rests on the anti-recoil seat 32, and the other end is tilted; when the carrier 10 moves forward along the track, the support foot 202 on the carrier 10 can push the tilted end away and pass smoothly; and when the carrier 10 tries to retreat, the drooping end will rest on the anti-recoil seat 32, thereby blocking its movement and achieving one-way anti-recoil.

[0047] See also Figure 1 、 Figure 2 、 Figure 7 As described, the first ferry conveying area 1 and the second ferry conveying area 3 have the same structure, wherein both have a longitudinal rail group 61 extending in the left and right directions, a ferry frame 62 and a first chain conveyor 63 driving the ferry frame 62 to slide are sliding on the longitudinal rail group 61, and a second transverse rail group 64 and a push-pull mechanism are provided on the ferry frame 62. The second transverse rail group 64 can be connected to the first transverse rail group 21, and the push-pull mechanism is used to drive the carrier 10 to move and convey on the first transverse rail group 21 and the second transverse rail group 64.

At the same time, the first rack 76 is fixed, and the push-pull guide shaft 72 is installed on one side of the base shell 71 so that it can slide back and forth. In order to improve the sliding stability of the push-pull guide shaft 72, guide wheels 200 are provided on its upper and lower sides, and the second rack 77 and the movable hook assembly are installed on the push-pull guide shaft 72; when working, the second chain conveyor 73 drives the chain to move, and the chain support base plate drives the gear 75 to move, and the gear 75 engages with the first rack 76. Since the first rack 76 is fixed, the gear 75 rotates, and the gear 75 rotates and engages with the second rack 77. Then, under the action of the second rack 77, the push-pull guide shaft 72 is driven to move back and forth, and the movable hook assembly hooks and pushes the carrier 10 to realize the push-pull transportation of the carrier between the track groups.
