[0032] Driving rotating roller 231 and driven rotating roller 232 form conveying surface when rotating, and hollow structure conveying belt 21 is laid on the conveying surface, and several bottle and can tooling 24 are arranged on conveying belt 21.Conveying belt 21 is composed of flat and long cross bar 211 and connecting belt 212 connected with cross bar 211, and a certain gap is kept between adjacent cross bar 211.The both ends of intermediate cross bar 211 are respectively provided with oppositely fixed first clamping groove 2111, and the middle part of adjacent two side cross bar 211 is provided with second clamping groove 2112 rotatably connected with cross bar 211.

[0033] The bottom of bottle and can tooling 24 is provided with horizontal cross beam 241 matched with first clamping groove 2111 and horizontal vertical beam 242 matched with second clamping groove 2112.The upper ends of cross beam 241 are respectively fixedly connected with vertical slide bar 243, and the upper end of slide bar 243 is embedded in the circumferential slide groove 244 at the bottom of tooling, and is slidably connected with the circumferential slide groove 244 at the bottom of tooling.The upper ends of vertical beam 242 are also respectively fixedly connected with vertical slide bar 243, and the upper end of slide bar 243 is embedded in the circumferential slide groove 244 at the bottom of tooling, and is slidably connected with the circumferential slide groove 244 at the bottom of tooling, so that bottle and can tooling 24 can be stable and not inclined when conveying belt 21 turns.Bottle and can tooling 24 and conveying belt 21 can also be provided with other detachable connections, so as to facilitate the disassembly, replacement and cleaning of bottle and can tooling 24.

[0034] The bottle and can tooling 24 is a rotary body, and an installation groove 245 with an opening facing upward is arranged in the bottle and can tooling 24, and an installation column 246 for extending into the interior of the bottle and can is arranged in the installation groove 245. When the bottle and can is cleaned, the bottle and can is impacted by the water flow sprayed by the spray gun, and the installation column 246 can support the interior of the bottle and can, so as to limit the angle of deflection of the bottle and can, further enhance the function of limiting the bottle and can, and prevent the bottle and can from tilting and rolling under the action of the water flow of the spray nozzle 321. An annular space for installing the bottle mouth of the bottle and can is formed between the installation column 246 and the side wall of the installation groove 245. The annular space formed between the installation column 246 and the side wall of the installation groove 245 can enhance the limiting function of the bottle and can, so as to reduce the activity space of the bottle and can, effectively improve the stability of the bottle and can, reduce the risk of shaking and mutual collision of the bottle and can during cleaning, and improve the safety and stability of the bottle and can during cleaning. Due to the reduced activity space of the bottle and can, the impact force between the bottle and can and the bottle and can tooling 24 can be reduced when the bottle and can collide, so as to avoid damage to the bottle mouth of the bottle and can.

[0035] The side wall of the installation groove 245 is further provided with a plurality of outer spring sheets 247 capable of elastically abutting against the outer surface of the bottle mouth, so as to facilitate and speed up the installation of the bottle and can, and reduce the collision between the bottle and can and the bottle and can tooling 24 during installation. The bottle mouth applies pressure to the outer spring sheet 247, so that the outer spring sheet 247 forms a squeezing effect on the bottle mouth, which is beneficial to improve the stability of the bottle and can, and eliminate the gap between the bottle mouth and the bottle and can tooling 24, so as to avoid shaking of the bottle and can during transportation and cleaning.

[0036] The plurality of outer spring sheets 247 arranged in the circumferential direction of the side wall of the installation groove 245 can uniformly stress the bottle mouth, enhance the clamping force received by the bottle and can, and reduce the vibration transmitted to the bottle and can by the rotating roller, so as to further enhance the stability of the bottle and can, and isolate the outer surface of the bottle mouth from the side wall of the installation groove 245, so as to avoid collision between the bottle mouth and the side wall of the installation groove 245 due to the influence of the vibration of the rotating roller. The installation column 246 is also provided with at least one inner spring sheet 248 capable of elastically abutting against the inner hole wall. The at least one inner spring sheet 248 can support the interior of the bottle mouth, apply an outward pushing force to the bottle mouth, and keep balance with the clamping force applied by the outer spring sheet 247, so as to limit the relative movement between the bottle mouth and the installation column 246, thereby enhancing the stability of the bottle and can and the vibration reduction effect.

[0037] The driving roller 231 drives the conveying belt 21, and the conveying belt 21 enters from one end of the support frame 1 and is output from the other end of the support frame 1 under the driving of the driving roller 231 and the rotation support of the driven roller 232. The conveying belt 21 is annular and can be circularly driven, so that the bottle and can tool 24 can be continuously produced, and the turnover efficiency of the bottle and can tool 24 can be improved. The length of the conveying belt 21 and the total number of the bottle and can tool 24 installed on the conveying belt 21 are designed according to the production scale.

[0038] The flushing device 3 is installed on the support frame 1 above the conveying device 2. The flushing device 3 comprises a second booster pump 31 for boosting the cleaning liquid, a liquid adding pipe 311, a flushing pipeline 32 and a pipeline 33, and two rows of nozzle assemblies spacedly arranged on the flushing pipeline 32. Each row of nozzle assemblies is provided with a plurality of nozzles 321, and the two rows of nozzle assemblies are inclined towards the center of the conveying surface of the conveying device 2 to spray the circumferential side of the workpiece on the conveying device 2. The nozzles 321 output pressure fluid to flush away the dust or impurities on the outer surface of the bottle and can, and the nozzles 321 are further provided with a cyclone member.

[0039] The second booster pump inlet is connected to the circulating water tank 44 and the liquid adding pipe 311 through the pipeline 33. The connecting pipeline 33 on one side of the liquid adding pipe 311 is provided with a first switch valve 3111, and the pipeline 33 on one side of the circulating water tank 44 is provided with a second switch valve 3112. The second booster pump outlet is connected to the flushing pipeline 32 through the pipeline 33. When the cleaning liquid in the circulating water tank 44 is insufficient, the first valve on one side of the liquid adding pipe 311 can be opened, and the second valve on one side of the circulating water tank 44 can be closed, so that the liquid adding pipe 311 is used to add cleaning liquid. When the cleaning liquid in the circulating water tank 44 is sufficient, the first valve on one side of the liquid adding pipe 311 can be closed, and the second valve on one side of the circulating water tank 44 can be opened, so that the circulating filtering device 4 is used to recycle and use the cleaning liquid, which obviously reduces the consumption of the cleaning liquid and is beneficial to reducing the production cost.

[0040] The circulating filtering device 4 is arranged on one side of the support frame 1, and comprises a recovery tank 41, a first booster pump 411, a filter 42, a heater 43 and a circulating water tank 44. The recovery tank 41 is arranged on the bottom of the support frame 1 below the conveying device 2. The first booster pump 411 is arranged in the recovery tank 41, and one end of the first booster pump 411 is connected to the cleaning liquid in the recovery tank through the pipeline 33, and the other end is connected to the inlet of the filter 42 through the pipeline 33. The outlet of the first booster pump 411 is connected to the inlet of the filter 42 through the pipeline 33, the outlet of the filter 42 is connected to the inlet of the heater 43 through the pipeline 33, the outlet of the heater 43 is connected to the inlet of the circulating water tank 44 through the pipeline 33, and the outlet of the circulating water tank 44 is connected to the inlet of the second booster pump 31 through the pipeline 33. The cleaning liquid gathered in the recovery tank 41 is pressurized by the first booster pump 411, and is sent into the filter 42 through the pipeline 33 for filtering. The filtered cleaning liquid is sent into the heater 43 through the pipeline 33 for heating. The cleaning liquid heated by the heater 43 flows into the circulating water tank 44 through the pipeline 33. The cleaning effect of the cleaning liquid after heating is better.

[0041] The support frame 1 on both sides of the conveying belt 21 is provided with a baffle 11. Since the sprayed cleaning liquid is more dispersed the farther it is from the nozzle 321, the top of the baffle 11 is bent towards the conveying belt 21, so that the distance from the nozzle 321 to the top of the baffle 11 can be reduced, and part of the cleaning liquid can be prevented from being excessively dispersed and leaving the effective range of the baffle 11, so that the excess cleaning liquid can be recycled to improve the recycling efficiency, and waste and environmental pollution can be avoided.

[0042] Working principle:

[0043] In the clamping area, the bottle cans are inserted upside down in the installation grooves 245 of the bottle can tooling 24, and the installation columns 246 extend into the interiors of the bottle cans, so that the bottle cans are installed on the bottle can tooling 24. The conveying belt 21 is used to convey the bottle cans into the flushing device 3 to clean and remove dust or other impurities on the bottle cans, so as to avoid the influence of the dust or other impurities on the paint spraying effect of the bottle cans. The cleaning liquid collected in the recovery tank 41 is pressurized by the first booster pump 411, and is sent into the filter 42 through the connected pipeline 33 for filtering. The filtered cleaning liquid is sent into the heater 43 through the pipeline 33 for heating. The heated cleaning liquid is sent into the circulating water tank 44 through the connected pipeline 33 for storage. The hot cleaning liquid stored in the circulating water tank 44 is pressurized again by the second booster pump 31 through the pipeline 33, and is sent to the flushing pipeline 32. The nozzle 321 connected to the flushing pipeline 32 sprays the cleaning liquid to clean and remove dust or other impurities on the bottle cans. The cleaning liquid not attached to the bottle cans falls into the recovery tank 41, and the cleaning liquid on the baffle 11 also slides into the recovery tank 41 for recycling. After the flushing of the bottle cans in the flushing device 3 is completed, the conveying device 2 is used to convey the bottle cans to the next process.
