When the spraying device is used specifically, firstly, the aluminum single plate body 240 to be sprayed is sleeved at the inner end of the clamping groove 231, the height of the aluminum single plate body 240 is adjusted through the main hydraulic rod 220, the clamping plate 230 is driven to rotate through the rotation of the servo motor 210, so that the angle of the aluminum single plate body 240 is adjusted, the aluminum single plate body 240 is sprayed through the spray head 310, meanwhile, the auxiliary hydraulic rod 330 drives the connecting plate 320 to slide downwards along the outer groove 120, the spray head 310 is driven to spray different positions of the aluminum single plate body 240, the connecting plate 320 drives the screw rod 110 to rotate in the downward movement process, the collecting box 130 is driven to move downwards along the inner end of the cabin body 10 in the rotation process of the screw rod 110, the collecting box 130 is made to be gradually close to the bottom end of the aluminum single plate body 240, and the sprayed liquid dropping in the spraying process at the moment flows to the inner end of the collecting box 130 to be collected.
In order to facilitate the operator to detach the collecting box 130 at regular intervals, in this embodiment, the upper and lower sides of the sliding block 131 are provided with the main clamping plates 132, the two main clamping plates 132 are respectively attached to the upper and lower sides of the collecting box 130, the upper and lower sides of the limiting head 133 are provided with the auxiliary clamping plates 134, the two auxiliary clamping plates 134 are respectively attached to the upper and lower sides of the collecting box 130, the bottom end of the bin 10 is provided with the slot, and the slot has a cross section size which is consistent with the cross section size of the collecting box 130. During the specific use, carry out the centre gripping to collecting box 130 both sides through main splint 132 and the vice splint 134 that set up spacing, can realize collecting box 130 horizontal free sliding work simultaneously to the collecting box 130 after will collecting full spraying liquid takes out storehouse body 10 inner, carries out reuse.
To improve the collecting effect, further, the collecting box 130 is provided with a plurality of inner slots 135 at each side of the inner end thereof. Because collecting box 130 all has certain thickness in each side, when leading to collecting spraying liquid, the spraying liquid that splashes down adheres to on collecting box 130 each side top very easily, and difficult clearance after the drying can lead to the collection effect step-down simultaneously, reduces collecting box 130 border thickness through the inboard groove 135 that sets up this moment, improves the collection effect.
In order to improve the disassembling efficiency of the collecting box 130, specifically, one side of the collecting box 130 is provided with a groove 136, and the inner end of the groove 136 is connected with a lifting rod 137. After the spraying liquid is fully collected at the inner end of the collecting box 130, the spraying liquid needs to be taken out, at the moment, an operator needs to buckle the side face of the collecting box 130 to drag the spraying liquid out, the surface of the collecting box 130 is smooth, the friction force is small, the slipping phenomenon easily occurs in the dragging process, at the moment, an application point of the operator is improved through the arranged lifting rod 137, the operator can indirectly drive the collecting box 130 to slip out of the inner end of the slot by buckling the lifting rod 137, and the disassembling efficiency of the collecting box 130 is improved.
In order to limit the sliding position of the collecting box 130, a fixing ring 141 is provided on the limiting rod 140, a sliding ring 142 is slidably connected to the limiting rod 140, a limiting spring 143 is connected to the top end of the sliding ring 142, and the other end of the limiting spring 143 is connected to the outer end of the limiting rod 140. The sliding position of the collecting box 130 is limited by the arranged sliding ring 142 and the limiting spring 143, and during specific use:
in the downward movement process of the collecting box 130, the fixing ring 141 is driven to move upward, when the fixing ring 141 slides to the bottom end of the sliding ring 142, the sliding ring 142 is pushed to slide upward, the limiting spring 143 is extruded in the sliding process of the sliding ring 142, the limiting spring 143 is in a compression state, and when the limiting spring 143 is compressed to the maximum limit, the sliding ring 142 cannot slide continuously, so that the problem that the top end of the collecting box 130 is rubbed and collided with the bottom end of the clamping plate 230 due to overlarge sliding amplitude of the collecting box 130 is avoided.
In addition, in order to improve the stability of the aluminum single plate body 240, L-shaped clamping blocks 250 are disposed at each corner of the inner end of the clamping groove 231, and each L-shaped clamping block 250 is attached to each corner of the aluminum single plate body 240. During the specific use, realize further centre gripping fixed work to aluminium veneer body 240 through the L type clamp splice 250 that sets up, improve aluminium veneer body 240 stability, reserve certain gap between aluminium veneer body 240 and the centre gripping groove 231 simultaneously, conveniently install and dismantle work.
In order to protect the outer ends of the secondary hydraulic rods 330, specifically, sleeve plates 331 are disposed outside the secondary hydraulic rods 330, and the side surfaces of the sleeve plates 331 are attached to the outside of the bin body 10. Because at carrying out the spraying in-process, spraying liquid can splash to all around, and the spraying liquid that splashes passes through outer groove 120 very easily and spouts to vice hydraulic stem 330 outer end, adheres to the vice hydraulic stem 330 outside, influences vice hydraulic stem 330 normal use, and the spraying liquid after the drying is difficult to wash simultaneously, carries out guard work to vice hydraulic stem 330 outer end through the lagging 331 that sets up this moment, avoids spraying liquid to contact vice hydraulic stem 330.
When the shaping bin for the spraying line of the embodiment is used specifically, firstly, the aluminum single plate body 240 to be sprayed is sleeved into the inner end of the clamping groove 231, so that each L-shaped clamping block 250 is sleeved on each corner of the aluminum single plate body 240, the height of the aluminum single plate body 240 is adjusted by the main hydraulic rod 220, the clamping plate 230 is driven to rotate by the rotation of the servo motor 210, thereby adjusting the angle of the aluminum single plate body 240, spraying the aluminum single plate body 240 through the nozzle 310, meanwhile, the auxiliary hydraulic rod 330 drives the connecting plate 320 to slide downwards along the outer groove 120, and drives the nozzle 310 to spray the aluminum veneer body 240 at different positions, and during the downward movement of the connecting plate 320, the screw rod 110 is driven to rotate, the collection box 130 is driven to move downwards along the inner end of the bin body 10 in the rotating process of the screw rod 110, the collection box 130 is enabled to be gradually close to the bottom end of the aluminum single plate body 240, and at the moment, the spraying liquid dropping in the spraying process flows to the inner end of the collection box 130 for collection.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
