Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.
[0023] The following is combined with Figure 1 To Attachment Figure 3 And specific embodiments describe the present invention in detail.
[0024] Reference Figure 1-3 The utility model provides a spraying safety protection mechanism, which is installed on a screw reciprocating spraying device 1. The screw reciprocating spraying device 1 includes a long strip support block 10, a slide groove 11 is provided on the top surface of the support block 10, and a screw 12 is rotatably connected between the two groove walls of the slide groove 11. The screw 12 is arranged along the length direction of the support block 10, and a driving motor 13 is installed at one end of the support block 10. The output shaft of the driving motor 13 is connected to the screw 12, and the driving motor 13 is used to drive the screw 12 to rotate; a slider 14 is threadedly connected to the screw 12, the screw 12 passes through the slider 14, the slider 14 slides in the slide groove 11, and a nozzle 15 is fixedly connected to the top surface of the slider 14, one end of the nozzle 15 extends out of the support block 10 and is arranged close to the roller, and the nozzle 15 is used to make the fuel incompletely burn on the surface of the roller, so that a layer of carbon powder with a lubricating effect is sprayed on the surface of the roller.
[0025] A support plate 2 is fixedly connected to the outer wall of the support block 10, and the support plate 2 is located on the side of the support block 10 that extends away from the nozzle 15. The support plate 2 is arranged along the length direction of the support block 10, and an L-shaped protective net 3 is arranged on the support plate 2. The protective net 3 cover is arranged on the screw reciprocating spraying device 1, and a gap is left between the protective net 3 and the support block 10 for the nozzle 15 to slide horizontally. A connecting plate 30 is fixedly connected to the end of the protective net 3 close to the support plate 2, and the connecting plate 30 is arranged along the length direction of the support plate 2. Four sleeves 31 are fixedly connected to the support plate 2, and the four sleeves 31 are arranged in an array along the length direction of the support plate 2. Four L-shaped plugs 32 are fixedly connected to the connecting plate 30, and the sleeves 31 and the plugs 32 are arranged one by one, and the plugs 32 are inserted in the sleeves 31.
[0026] Four limiting components 4 are arranged on the support plate 2, and the limiting components 4 are used to limit the insertion column 32 from sliding out of the sleeve 31. The limiting components 4 include a limiting plate 40, and the limiting plate 40 vertically penetrates and slides in the support plate 2. The limiting plate 40 is located on the side of the insertion column 32 away from the sleeve 31. The limiting plate 40 is used to prevent the insertion column 32 from sliding out of the sleeve 31. A connecting rod 41 is fixedly connected to the bottom end of the limiting plate 40, and a first fixing plate 42 is fixedly connected to the bottom end of the connecting rod 41. A first tension spring 43 is fixedly connected between the surfaces, and the connecting rod 41 is inserted into the first tension spring 43. The first tension spring 43 has a tendency to drive the first fixed plate 42 to move toward the direction close to the support plate 2; two limit blocks 44 are fixedly connected to the connecting rod 41, and the limit blocks 44 are located inside the first tension spring 43. The limit blocks 44 abut against the bottom surface of the support plate 2. The limit blocks 44 are used to limit the movement range of the limit plate 40 under the action of the first tension spring 43 to prevent the limit plate 40 from moving excessively upward and sliding out of the support plate 2.
[0027] When installing the protective net 3, the plug post 32 presses the limit plate 40 downward, so that the limit plate 40 slides into the support plate 2, and the plug post 32 is aligned with the sleeve 31 and inserted into the sleeve 31. When the plug post 32 is fully inserted into the sleeve 31, the first tension spring 43 drives the limit plate 40 to move upward through the first fixed plate 42 and the connecting rod 41.

The protective net 3 is installed and the protective net 3 can be flipped over; when disassembling the protective net 3, pull the first fixed plate 42 downward, and the first fixed plate 42 drives the limit plate 40 to move through the connecting rod 41, and the limit plate 40 slides into the support plate 2, and then the plug post 32 slides out of the sleeve 31 to remove the protective net 3, which is convenient for replacing the protective net 3.
[0028] L-shaped reinforcing plates 5 are fixedly connected at both ends of the protective net 3, and plugs 50 are fixedly connected to the reinforcing plates 5. Fixed blocks 51 are fixedly connected to the top surfaces of both ends of the support block 10. A slot 510 is opened in the fixed block 51, and the plug 50 is inserted in the slot 510. The protective net 3 is mounted on the support block 10 through the plug 50 and the fixed block 51.
[0029] A locking assembly 6 is provided on the fixed block 51, and the locking assembly 6 is used to lock the plug 50 to prevent the plug 50 from detaching from the fixed block 51. The locking assembly 6 includes a locking rod 60, which is slidably connected to the fixed block 51. One end of the locking rod 60 passes through the fixed block 51, and a locking hole 500 is opened in the plug 50. The locking rod 60 is inserted into the locking hole 500. One end of the locking rod 60 that passes through the fixed block 51 is fixedly connected to a second fixed plate 61, and a second tension spring 62 is fixedly connected between the second fixed plate 61 and the side wall of the fixed block 51. The second tension spring 62 has a tendency to drive the second fixed plate 61 to move toward the fixed block 51.
[0030] After the protective net 3 is installed, the protective net 3 is rotated so that the protective net 3 cover is set on the screw reciprocating spray device 1. At this time, the insert 50 is inserted into the slot 510, and the locking rod 60 is inserted into the locking hole 500 under the action of the second tension spring 62, thereby preventing the insert 50 from detaching from the fixing block 51, thereby improving the stability of the protective net 3.
