[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Depend on Figures 1 to 5The invention comprises a supporting frame 1 and a collecting barrel 2 placed under the supporting frame 1. A placing box 3 is arranged on the top of the supporting frame 1. A plurality of filter holes 4 are opened on the bottom of the placing box 3. Through the above-mentioned supporting frame 1, collecting barrel 2 and placing box 3, when spraying the cold iron, it is only necessary to place the cold iron neatly in the placing box 3 in sequence, and use a spraying tool to spray the cold iron directly. The excess paint is recovered into the collecting barrel 2 through the filter holes 4 below, so as to achieve the effect of reuse. At the same time, the placing box 3 can be placed directly next to the core making machine to avoid workers bending over to get the cold iron from the barrel, which greatly reduces the labor intensity of the workers. A rotating frame 5 matching the placing box 3 is rotatably connected to one side of the supporting frame 1, and connecting columns 6 are fixed to the top four corners of the rotating frame 5. , the four connecting columns 6 are slidably connected with the same connecting frame 7, the connecting frame 7 is connected to the rotating frame 5 by a spring, the bottom of the connecting frame 7 is fixed with a cover plate 8 matching the placement box 3, and the bottom of the cover plate 8 is fixed with a plurality of top columns 9 matching the filter holes 4. During the long-term use of the placement box 3, the paint or other foreign matter is easy to clog the filter holes 4. If the impurities in the filter holes 4 are removed one by one by manpower, it is very time-consuming and laborious. Through the arrangement of the rotating frame 5, the cover plate 8 and the top column 9, the rotating frame 5 is turned over and covered on the placement box 3. At this time, the cover plate 8 is located inside the placement box 3, and the connecting frame 7 is pressed downward. The cover plate 8 contacts the bottom surface of the placement box 3, and the plurality of top columns 9 penetrate the corresponding filter holes 4 to remove the impurities remaining inside the filter holes 4;

[0028] Considering that the method of manually flipping the rotating frame 5 is a bit laborious, a rotating shaft 10 is rotatably connected to one side of the support frame 1, and a rotating gear 11 is coaxially fixed on the rotating shaft 10. A connecting shaft 12 is provided at the hinge of the rotating frame 5 and the support frame 1, and a half gear 13 meshing with the rotating gear 11 is fixed at one end of the connecting shaft 12. The distribution of teeth on the half gear 13 is less than one-half, and a transmission motor 14 is provided at the end of the rotating shaft 10 away from the support frame 1. When the transmission motor 14 is started, the rotating gear 11 drives the half gear 13 to rotate, and the flipping angle of the rotating frame 5 is less than 180 degrees. Through the settings of the transmission motor 14, the half gear 13 and the rotating gear 11, the transmission motor 14 drives the rotating frame 5 to flip, which is more time-saving and labor-saving than manual flipping.

[0029] Taking into account that paint is easy to adhere to the side wall of the placement box 3, it is very inconvenient to clean after a long time. The four corners of the connecting frame 7 are rotatably connected with a transmission shaft 15, and four rollers 16 are coaxially fixed on the four transmission shafts 15. The rollers 16 are provided with a connecting groove. When the synchronous belt transmission method is not adopted, the cross-section of the connecting groove is "V"-shaped, which is used to increase friction. The same cleaning belt 17 is arranged on the four rollers 16. A plurality of cleaning wires 18 are fixed on the cleaning belt 17. The cleaning wire 18 has a certain hardness, similar to the bristle wire on a hard brush. A cleaning motor is arranged on the top of one of the transmission shafts 15. Through the transmission shaft 15, the roller 16 and the cleaning belt 17, the cleaning motor drives the roller 16 to rotate, and the cleaning belt 17 rotates under the drive of the roller 16, similar to the belt transmission method. The cleaning wire 18 cleans the side wall of the placement box 3, which greatly improves the cleaning efficiency of the placement box 3.

[0030] refer to Figure 6 As shown, in order to reduce the weight of the rotating frame 5 when it is flipped, a connecting plate 19 is fixed on the side wall of the support frame 1, and a conduction shaft 20 is rotatably connected to the connecting plate 19, and a first bevel gear 21 is coaxially fixed to the conduction shaft 20, and the conduction shaft 20 is connected to the rotating shaft 10 through a belt transmission structure. A positioning shaft 22 is rotatably connected to the top of the connecting frame 7, and a second bevel gear 23 is coaxially fixed to the positioning shaft 22. The positioning shaft 22 is connected to one of the transmission shafts 15 through a belt transmission structure. Through the conduction shaft 20, the first bevel gear 21 and the second bevel gear 23, the transmission motor 14 is used as a power source for rotating the cleaning belt 17. After the transmission motor 14 is started to flip the rotating frame 5 over, the first bevel gear 21 is meshed with the second bevel gear 23. As the transmission motor 14 continues to rotate, the roller 16 and the cleaning belt 17 rotate under the transmission of the first bevel gear 21 and the second bevel gear 23.

[0031] refer to Figure 7 As shown, considering that when pressing down the connecting frame 7, it is necessary to press it manually, which is rather troublesome, limiting columns 24 are fixed on both sides of the top of the rotating frame 5, and a limiting groove 25 is provided on the limiting column 24. A pin is provided on the top of the limiting groove 25, and a limiting block 26 is rotatably connected to the pin. The limiting block 26 is connected to the limiting groove 25 by a spring, and a limiting hole matching the limiting column 24 is provided on the connecting frame 7. Through the settings of the limiting column 24, the limiting groove 25 and the limiting block 26, when the worker presses down the connecting frame 7, the limiting block 26 is squeezed by the connecting frame 7 and shrinks into the limiting groove 25. When the connecting frame 7 is located below the limiting groove 25, the limiting block 26 pops outward under the action of the spring, thereby achieving the effect of rapid limiting, and human pressure is no longer required.

[0032] In order to ensure the cleaning effect of the cleaning wire 18 on the placement box 3, the cleaning wire 18 is made of soft iron wire, brass wire or any material with moderate hardness.

[0033] In order to prevent the roller 16 and the cleaning belt 17 from sliding and affecting the cleaning effect of the placement box 3, the cleaning belt 17 and the four rollers 16 are in the form of synchronous belt transmission.

[0034] In order to facilitate the movement of the support frame 1, universal wheels are arranged at the four bottom corners of the support frame 1.

[0035] When the utility model is used:

[0036] First, place the placement box 3 on the support frame 1, place the chillers neatly inside the placement box 3, and then use a spraying tool to spray the chillers;

[0037] Then, when it is necessary to clean the placement box 3, all the cold iron inside is taken out, the transmission motor 14 is started, the rotating frame 5 is flipped and finally located above the placement box 3, the connecting frame 7 is pressed downward, the cover plate 8 contacts the bottom surface of the placement box 3, and multiple top columns 9 penetrate the corresponding filter holes 4 to remove the impurities remaining in the filter holes 4. At the same time, when the worker presses down the connecting frame 7, the limit block 26 is squeezed by the connecting frame 7 and shrinks into the limit groove 25. When the connecting frame 7 is located below the limit groove 25, the limit block 26 pops outward under the action of the spring, and at this time the connecting frame 7 and the limit block 26 form a limit.

[0038] Secondly, as the transmission motor 14 continues to work, under the conduction of the first bevel gear 21 and the second bevel gear 23 and other components, the roller 16 drives the cleaning belt 17 to rotate, and the cleaning wire 18 cleans the side wall of the placement box 3;

[0039] Finally, when the placement box 3 is cleaned, the limit block 26 is manually squeezed into the limit groove 25, the connecting frame 7 is reset upward under the action of the spring, the transmission motor 14 is reversed, the rotating gear 11 and the half gear 13 are engaged again, the rotating frame 5 is flipped to one side, and the placement box 3 can continue to be used.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
