[0032] The present invention will be further described in detail below in conjunction with the drawings.
[0033] Reference figure 1 , Is a workpiece hoisting and spraying production line disclosed by the present invention, including a hoisting conveyor 1, a loading station 2, which is sequentially arranged on the lower side of the hoisting conveyor 1, a spray cleaning station 33, a spraying station 4, and a drying station 5 and unloading station 6.
[0034] Reference figure 1 with figure 2 The hoisting and conveying device 1 includes a conveying track 11 and a number of hoisting racks 12 arranged on the conveying track 11. The conveying track 11 has a waist-shaped ring structure, and both ends of the conveying track 11 are rotatably connected with a synchronous gear plate with a vertical axis. 111. The transmission track 11 corresponds to a synchronous gear plate 111. A drive motor 112 capable of driving the synchronous gear plate 111 is fixedly connected to the lower side. The two synchronous gear plates 111 are also sleeved with synchronous toothed belts 113 and synchronous toothed belts 113. The inner side meshes with the two synchronous gear plates 111, and the outer side of the synchronous toothed belt 113 is evenly connected with external synchronous teeth 1131. The hoisting frame 12 includes a sliding block 121 connected to the conveying track 11 along the trajectory of the conveying track 11. The sliding block 121 close to the synchronous toothed belt 113 is also fixedly connected to a limiting tooth 1211, and the limiting tooth 1211 can be engaged with the outside. Synchronous teeth 1131. During operation, the driving motor 112 drives the synchronous gear plate 111 to rotate, which can drive the synchronous toothed belt 113 to rotate, so that the external synchronous teeth 1131 of the synchronous toothed belt 113 can mesh with the limit teeth 1211 of the slider 121 to drive the slider 121 along the conveying track. 11 to move.
[0035] Reference figure 1 with image 3 The hoisting frame 12 also includes a support shaft 122 vertically arranged and the upper end of which passes through the slider 121.

The gear 1221 is also fixedly connected to the rack 114 at positions on the conveying track 11 corresponding to the cleaning station 3, the spraying station 4 and the drying station 5, and the rotating gear 1221 can mesh with the rack 114. In operation, when the sliding block 121 moves to drive the rotating gear 1221 to the position where the rack 114 is provided on the conveying track 11, the rotating gear 1221 can mesh with the rack 114, so that the rotating gear 1221 rotates, thereby driving the support shaft 122 to rotate.
[0036] The lower end of the support shaft 122 is provided with a hook body 123, one end of the hook body 123 is rotatably connected to the lower end of the support shaft 122, and the side of the support shaft 122 away from the hook body 123 is rotatably connected to a vertically arranged telescopic cylinder 124. The telescopic rod is arranged downward and is rotatably connected to an end of the hook body 123 close to the support shaft 122. When the telescopic cylinder 124 drives the telescopic rod to contract upward to the extreme position, the hook body 123 can rotate downward, so that the workpiece hanging on the hook body 123 falls off downwards. When the telescopic rod of the telescopic cylinder 124 extends downward to the extreme position, The hook body 123 can rotate upward to a horizontal state. A control circuit is also provided on the transport track 11 (refer to Figure 7 ), the control circuit includes a detection module 7 and a control module 8 and a reset module 9 arranged in the telescopic cylinder 124. The detection module 7 includes a travel switch 115 arranged on the side of the conveying track 11 and located at the position of the blanking station 6 When the slider 121 moves to the conveying track 11 at the position of the unloading station 6, one side of the slider 121 can abut the travel switch 115, so that the travel switch 115 is turned on, the detection module 7 sends a signal, and the control module 8 receives Detect the signal sent by the module 7 and control the contraction of the telescopic rod of the telescopic cylinder 124 so that the hook body 123 rotates downward, so that the workpiece hung on the upper side of the hook body 123 automatically falls; the reset module 9 can also receive the control module 8 When the reset module 9 cannot receive the signal sent by the detection module 7, the reset module 9 controls the telescopic rod of the telescopic cylinder 124 to extend outward, so that the hook body 123 rotates upward to reset.
[0037] The upper side of the hook body 123 is vertically provided with a receiving groove 1231. One end of the receiving groove 1231 close to the support shaft 122 is vertically slidably connected to a pressing block 1232 projecting from the upper side of the receiving groove 1231. The receiving groove 1231 There is also a limit rod 1233 rotatably connected to the accommodating groove 1231 in the middle. Under normal conditions, both ends of the limit rod 1233 can be located in the accommodating groove 1231, and one end of the limit rod 1233 is located on the lower side of the pressure block 1232. , Pressing the pressing block 1232 to a horizontal state, the pressing block 1232 can drive the end of the limiting rod 1233 located at the pressing block 1232 to rotate downward, so that the end of the limiting rod 1233 away from the pressing block 1232 rotates upwards until it protrudes from the receiving groove 1231 The upper side of the hook body 123 further restricts the workpiece on the upper side of the hook body 123 to prevent the workpiece from slipping off the end of the hook body 123 away from the support shaft 122. A return spring 1234 is vertically fixed in the accommodating groove 1231 at a position corresponding to the lower side of the pressure block 1232. The upper end of the return spring 1234 is fixed to the lower side of the limit rod 1233 at the position of the pressure block 1232. When falling, the upper side of the pressure block 1232 loses force, and the return spring 1234 can push the limit rod 1233 on the lower side of the pressure block 1232 to rotate upward, thereby pushing the pressure block 1232 to rise to complete the reset.
[0038] The loading station 2 includes a loading conveyor belt 21 that is horizontally arranged and one end is located on the lower side of the conveying track 11. The feeding conveyor belt 21 can convey the workpiece in a direction close to the conveying track 11.

[0039] Reference figure 1 with Figure 4 The spray cleaning station 3 includes a spray cleaning box 31 arranged at one end of the conveying track 11. The spray cleaning box 31 is provided with a first through slot 311 that can facilitate the insertion of the lower end of the lifting frame 12 into the spray cleaning box 31 on the upper side. On both sides of the conveying trajectory of the corresponding hoisting frame 12 are provided with a number of spray guns 32 capable of spraying air to the workpiece, and the outer side of the blowout box 31 is fixed with a gas tank 33 capable of conveying gas to the spray gun 32, and the blowout box 31 Corresponding to the position of the lower side of the hoisting frame 12 along the movement track of the hoisting frame 12 is fixedly connected with a blanking trough 34, the lower side of the blanking trough 34 has several dust outlets, and the lower side of each dust outlet is connected with bolts The cloth dust bag 35, the blower box 31 corresponding to the position on the lower side of each dust collection belt are fixedly connected with the exhaust fan 36, the side door 37 is provided on the side of the blower box 31 corresponding to the position of each dust bag 35, open The side door 37 can facilitate taking out the dust collecting bags 35, and both ends of the blowout box 31 are also fixedly connected to the first flexible dust curtain 38. During work, when the workpiece moves with the hoisting frame 12 into the cleaning box 31, the high-pressure air pump can spray air on the workpiece hanging on the hoisting frame 12, and since the workpiece is transferred to the cleaning station 3, the support shaft 122 can drive the original workpiece. The position is rotated, so that the workpiece can be cleaned in all directions. At the same time, the exhaust fan 36 works to draw the dust in the blowout box 31 down to the dust bag 35 under the blanking trough 34, thereby completing the passage The dust collecting bag 35 completes the dust collection. After finishing the work, open the side door 37 and take out the dust collecting belt and dump it.
