Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically a coating processing equipment for large pressure tank lids. Background Technology

[0002] Pressure tank lid coating equipment refers to industrial equipment specifically designed for surface coating treatment of tank lids. Its core function is to uniformly coat the surface of aluminum materials with functional coatings through automated or semi-automated processes to meet the usage requirements of the tank body under high pressure, corrosive media, or extreme environments.

[0003] Existing pressure tank lid coating equipment mostly uses linear feeding when conveying and coating aluminum materials. The equipment is linearly set up, occupies a large area, and is not suitable for small workshops. During coating, the existing scraping structure is mostly fixed, or it is not convenient to adjust the distance between the scraping component and the aluminum material, making it impossible to flexibly control the coating thickness. A single machine is not convenient for producing different can lids. Furthermore, during the production process, the coating is directly dried. When the coating is dried directly by a heat source at a low temperature, the coating may crack. Therefore, a large-scale pressure tank lid coating equipment is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a large pressure tank cover material coating processing equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large pressure tank lid coating processing equipment, comprising a shell, a coating component disposed inside the shell, a first support roller disposed inside the shell at the rear end of the coating component, a second support roller disposed inside the shell below the first support roller, aluminum material disposed on the outer surfaces of both second support rollers, a support member disposed inside the shell at the rear end of the aluminum material, a collection box disposed at the top of the support member, a scraping component disposed at the top of the collection box, an electric push rod connected to one end of the scraping component and the support member, and a drying chamber disposed inside the shell below the coating component, a preheating component disposed at one end of the drying chamber facing the aluminum material.

[0006] Preferably, the front shell of the coating assembly has two feed rollers inside, and the shell below the feed rollers has two cooling rollers inside. The two cooling rollers are connected to a cooling pipe. One end of the cooling pipe extends out of the shell, and the extended end of the cooling pipe is equipped with a circulation box. When coating the aluminum material for the can lid, the aluminum material is conveyed into the shell through the unwinding assembly. The aluminum material passes through the two feed rollers, the coating assembly, the drying box, and the two cooling rollers in sequence. After the aluminum material is coated with the paint, it is dried. When it passes through the two cooling rollers after drying, it is cooled by the cooling pipe, so that the paint adheres to the surface of the aluminum material. The cooling pipe contains coolant. After the coolant undergoes heat exchange, it is circulated through the circulation box to keep the coolant inside the cooling pipe at a low temperature.

[0007] Preferably, the coating assembly is a square component with openings at both the front and rear ends. The aluminum material passes through the coating assembly, and a paint tank is provided at the top of the coating assembly. When the aluminum material passes through the coating assembly, the nozzles provided inside the coating assembly above the aluminum material spray paint onto the top of the aluminum material, so that the paint adheres to the surface of the aluminum material.

[0008] Preferably, two guide grooves are provided at the top two sides of the support member. The collection box is connected to the paint box through a hose. The two guide grooves limit the movement of the collection box, allowing the paint box to move linearly, which facilitates the adjustment of the distance between the scraping assembly and the aluminum material.

[0009] Preferably, the drying oven has two heating plates inside, and the drying oven has a through opening through which the aluminum material passes. The heating plates are made of iron-chromium-aluminum alloy. When the heating plates conduct electricity, they generate heat, which is conducted to the surface of the aluminum material to dry the coating and ensure that the coating can be quickly cured and adhered to the surface of the aluminum material.

[0010] Preferably, one end of the preheating component is provided with a copper pipe facing the drying chamber. The copper pipe extends above the heating plate inside the drying chamber. When the heating plate heats up, the copper pipe absorbs the heat generated by the heating plate. A centrifugal gas circulation pump is provided at one end of the copper pipe to circulate the gas inside the copper pipe with the gas inside the preheating component, transferring heat to the inside of the preheating component. One end of the preheating component is in contact with the aluminum material, and the heat will heat the aluminum material, preheating it and improving the subsequent drying efficiency.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This large pressure tank cover coating processing equipment has a first and a second vertically set support roller inside the outer shell. When the aluminum material is conveyed and coated inside the outer shell, the aluminum material moves in a U-shape and does not use lateral linear movement, thus reducing the footprint of the coating processing equipment.

[0013] 2. This large pressure tank lid coating processing equipment uses a scraper assembly supported by a support member. The scraper assembly can move linearly, and the distance between the scraper assembly and the aluminum material can be adjusted to adjust the coating on the aluminum surface, so that thicker coatings are scraped off, improving the uniformity of the coating. Adjusting the distance between the scraper assembly and the aluminum material is easy and allows for flexible adjustment of the coating thickness, making it convenient to meet the production needs of different can lids.

[0014] 3. This large pressure tank cover coating processing equipment uses a drying box and a preheating component in conjunction. After the aluminum coating and scraping operations are completed, the preheating component preheats the uncoated surface of the aluminum material, so that the coating is initially cured on the surface of the aluminum material. Then, it is dried to avoid the coating being directly heated by high temperature and causing cracks. This allows the coating to be completely cured and the adhesion speed to be faster, thus improving production efficiency. Attached Figure Description

[0024] like Figures 1 to 6 As shown, the large pressure tank lid coating processing equipment of this embodiment includes a housing 1, a coating assembly 5 is arranged inside the housing 1, an opening is provided at the front end of the coating assembly 5, an aluminum material 2 passes through the coating assembly 5, a coating nozzle is arranged inside the coating assembly 5 above the aluminum material 2 to spray coating material onto the outer surface of the aluminum material 2, a first support roller 7 is arranged inside the housing 1 at the rear end of the coating assembly 5, and a second support roller 9 is arranged inside the housing 1 below the first support roller 7. When the aluminum material 2 is conveyed inside the housing 1, the first support roller 7... The aluminum material 2 is guided, converting its horizontal movement into horizontal movement. The second support roller 9 guides the aluminum material 2, converting its horizontal movement into vertical conveying. The coated aluminum material 2 is conveyed to the front end of the outer shell 1 and connected to the winding assembly. The winding assembly applies traction to the aluminum material 2, allowing it to move inside the outer shell 1, reducing the equipment's footprint. The outer surfaces of both second support rollers 9 are coated with aluminum material 2. A support member 6 is installed inside the outer shell 1 at the rear end of the aluminum material 2. A collection box 12 is installed at the top of the support member 6 to collect the material. A scraper assembly 13 is installed at the top of the collection box 12. The top of the scraper assembly 13 is inclined near the aluminum material 2. One end of the scraper assembly 13 is connected to an electric push rod 18 via a support member 6. The output end of the electric push rod 18 drives the collection box 12 to move linearly at the top of the support member 6, adjusting the distance between the inclined surface of the scraper assembly 13 and the aluminum material 2 to scrape away thicker coatings, making the coating more uniform. After coating is completed, the distance between the scraper assembly 13 and the aluminum material 2 is controlled to control the coating thickness, in order to cope with the production of different can lids. To meet production needs, a drying chamber 14 is installed inside the outer shell 1 below the coating component 5. A preheating component 8 is installed at one end of the drying chamber 14 facing the aluminum material 2. The preheating component 8 contacts the uncoated outer surface of the aluminum material 2 and collects the residual heat of the drying chamber 14. After the coating and scraping operations are completed, the aluminum material 2 is heated by the preheating component 8 for preliminary heating to allow the coating to undergo preliminary curing. After preliminary curing, the aluminum material 2 enters the drying chamber 14 for double-sided heating and drying to ensure that the coating is thoroughly heated and adhered to the outer surface of the aluminum material 2.

[0025] Specifically, the front shell 1 of the coating assembly 5 is equipped with two feed rollers 11, and the shell 1 below the feed rollers 11 is equipped with two cooling rollers 10. The two cooling rollers 10 are connected to a cooling pipe 19. One end of the cooling pipe 19 extends out of the shell 1, and the extended end of the cooling pipe 19 is equipped with a circulation box 3. When coating the aluminum material 2 for the can lid, the aluminum material 2 is conveyed into the shell 1 through the unwinding assembly. The aluminum material 2 passes through the two feed rollers 11, the coating assembly 5, the drying box 14 and the two cooling rollers 10 in sequence. After the surface of the aluminum material 2 is coated with paint, it is dried. When it passes through the two cooling rollers 10 after drying, it is cooled by the cooling pipe 19, so that the paint adheres to the surface of the aluminum material 2. The cooling pipe 19 contains coolant. After the coolant undergoes heat exchange, it is circulated through the circulation box 3, so that the coolant inside the cooling pipe 19 is in a low temperature state.

[0026] Furthermore, the coating component 5 is a square component with openings at both the front and rear ends. The aluminum material 2 passes through the coating component 5, and a paint box 4 is provided at the top of the coating component 5. When the aluminum material 2 passes through the coating component 5, the nozzle provided inside the coating component 5 above the aluminum material 2 sprays the paint onto the top of the aluminum material 2, so that the paint adheres to the surface of the aluminum material 2.

[0027] Furthermore, two guide grooves 17 are provided on both sides of the top edge of the support member 6. The collection box 12 is connected to the paint box 4 through a hose. The two guide grooves 17 limit the collection box 12, so that the paint box 4 can move linearly, which facilitates the adjustment of the distance between the scraping assembly 13 and the aluminum material 2.

[0028] Furthermore, the drying oven 14 is equipped with two heating plates 15 inside. The drying oven 14 has an opening through which the aluminum material 2 passes. The heating plate 15 is made of iron-chromium-aluminum alloy. When the heating plate 15 conducts electricity, it generates heat, which is conducted to the surface of the aluminum material 2 to dry the coating and ensure that the coating can be quickly cured and adhered to the surface of the aluminum material 2.

[0029] Furthermore, a copper pipe 16 is installed at one end of the preheating component 8 facing the drying chamber 14. The copper pipe 16 extends above the heating plate 15 inside the drying chamber 14. When the heating plate 15 heats up, the copper pipe 16 absorbs the heat generated by the heating plate 15. A centrifugal gas circulation pump is installed at one end of the copper pipe 16, which circulates the gas inside the copper pipe 16 with the gas inside the preheating component 8, transferring heat to the inside of the preheating component 8. One end of the preheating component 8 is in contact with the aluminum material 2, and the heat will heat the aluminum material 2, preheating it and improving the subsequent drying efficiency.

[0030] The method of use in this embodiment is as follows: When the aluminum material 2 is coated, the aluminum material 2 is conveyed into the housing 1 by the unwinding assembly. The aluminum material 2 passes through two feed rollers 11, the coating assembly 5, the drying box 14, and two cooling rollers 10 in sequence. The first support roller 7 guides the aluminum material 2, converting the horizontal movement of the aluminum material 2 into horizontal movement. The second support roller 9 guides the aluminum material 2, converting the horizontal movement of the aluminum material 2 into vertical conveying. The coated aluminum material 2 is conveyed to the front end of the housing 1 and connected to the winding assembly. The winding assembly applies traction force to the aluminum material 2. When the aluminum material 2 passes through the coating assembly 5, a coating nozzle is provided inside the coating assembly 5 above the aluminum material 2 to spray the coating onto the outer surface of the aluminum material 2. After the aluminum material 2 is coated, the aluminum material 2 is guided by the first support roller 7 and moves towards the scraper. The material component 13 moves, and the output end of the electric push rod 18 drives the material collection box 12 to move linearly at the top of the support 6. The distance between the inclined surface of the scraping component 13 and the aluminum material 2 is adjusted to scrape off the thicker coating, making the coating more uniform. The coating thickness is controlled by controlling the distance between the scraping component 13 and the aluminum material 2. The scraped coating falls into the material collection box 12 and is transported back to the coating box 4 through the hose for recycling to meet the production needs of different can lids. After the coating and scraping operations are completed, the aluminum material 2 is heated by the preheating component 8 for preliminary heating to allow the coating to initially cure. After preliminary curing, the aluminum material 2 enters the drying oven 14 for double-sided heating and drying, so that the coating is heated and cured and adheres to the outer surface of the aluminum material 2.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
