Description

Technical Field

[0001] The utility model belongs to the technical field of cast iron pot production, and particularly relates to a non-stick coating spraying device for cast iron pots. Background Art

[0002] After the cast iron pot is coated, a relatively stable protective film is formed at the surface defects such as flaws, thereby further preventing the iron pot from rusting. For people who don't want to spend too much time on cleaning, the coated pot body is easier to clean and hygienic, and finally the traditional style of the cast iron pot can be retained.

[0003] Comparing with the Chinese patent with the publication number of CN108580078A, it discloses a cast iron pot coating spraying device with a coating homogenization function, including an operating table and legs. The lower end of the operating table is fixedly connected with legs, and two groups of fixing frames are fixedly installed on the upper end of the operating table. A lifting device is arranged at the upper end of the fixing frame, and the fixing frame is fixedly connected with the lifting device through a fixing seat. A cross bar is fixedly installed at the upper end of the lifting device. A paint box is fixedly installed on the upper end of the operating table outside the fixing frame, and a pipeline is fixedly connected to the upper end of the paint box. One end of the pipeline is fixedly connected with the paint box through an oil pump.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 5 , a non-stick coating spraying device for cast iron pans, including a spray assembly for telescopic atomizing spraying of non-stick coatings, and further including a frame assembly for magnetically attracting and suspending the cast iron pan. A storage assembly for storing the non-stick coating solution and sucking and recovering atomized droplets is arranged below the frame assembly, and the spray assembly is installed in the middle of the frame assembly.

[0025] In this embodiment: The frame assembly includes a workbench 101. A fixed frame 102 is arranged on the workbench 101. The fixed frame 102 and the workbench 101 are welded together. A positioning block 103 is installed at the top of the fixed frame 102. The positioning block 103 and the fixed frame 102 are bolted together. A positioning groove 104 is arranged below the positioning block 103. The positioning groove 104 is concave arc-shaped. An electromagnet 105 is arranged at the top of the positioning groove 104. The electromagnet 105 and the positioning block 103 are bolted together. The cast iron pan is closely attached to the positioning groove 104, so that the electromagnet 105 adsorbs the cast iron pan on the positioning block 103 supported by the fixed frame 102, forming an inverted state of the cast iron pan;

[0026] In this embodiment: The spray assembly includes two telescopic cylinders 201 symmetrically arranged. An elevating frame 202 is installed between the telescopic ends of the telescopic cylinders 201. An atomizing nozzle 203 is installed in the middle of the elevating frame 202. A delivery hose 204 is installed at the bottom end of the atomizing nozzle 203. The delivery hose 204 is connected to the atomizing nozzle 203 and the booster pump 205 by clamps respectively. A booster pump 205 is installed at the bottom end of the delivery hose 204. A rigid straight pipe 206 is installed below the booster pump 205. The workbench 101 supports the telescopic cylinder 201 to extend and push the elevating frame 202 to drive the atomizing nozzle 203 to rise and insert into the cast iron pot. The booster pump 205 extracts the non-stick coating solution in the liquid storage tank 301 through the rigid straight pipe 206 and transports it to the atomizing nozzle 203 through the delivery hose 204, and atomizes and sprays it onto the surface of the cast iron pot for non-stick coating spraying;

[0027] In this embodiment: The storage assembly includes a liquid storage tank 301. Two return pipes 302 are symmetrically arranged at the top of the liquid storage tank 301. The return pipes 302 pass through the workbench 101. A collecting hopper 303 is arranged at the top end of the return pipes 302. The collecting hopper 303 is in the shape of an inverted frustum of a cone and is welded to the return pipes 302. A barrier net 304 is installed in the collecting hopper 303. Two negative pressure pumps 305 are symmetrically installed on the front of the liquid storage tank 301. The negative pressure pumps 305 extract the air at the top of the liquid storage tank 301 to form a negative pressure, and collect the excess atomized liquid droplets into the liquid storage tank 301 through the return pipes 302 and the collecting hopper 303 for recycling. The barrier net 304 prevents sundries from entering the liquid storage tank 301.

[0028] Working principle: Press the cast iron pot tightly against the positioning groove 104 so that the electromagnet 105 adsorbs the cast iron pot on the positioning block 103 supported by the fixing frame 102 to form an inverted state of the cast iron pot. The workbench 101 supports the telescopic cylinder 201 to extend and push the elevating frame 202 to drive the atomizing nozzle 203 to rise and insert into the cast iron pot. The booster pump 205 extracts the non-stick coating solution in the liquid storage tank 301 through the rigid straight pipe 206 and transports it to the atomizing nozzle 203 through the delivery hose 204, and atomizes and sprays it onto the surface of the cast iron pot for non-stick coating spraying. At the same time, the negative pressure pumps 305 extract the air at the top of the liquid storage tank 301 to form a negative pressure, and collect the excess atomized liquid droplets into the liquid storage tank 301 through the return pipes 302 and the collecting hopper 303 for recycling. The barrier net 304 prevents sundries from entering the liquid storage tank 301.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
