Description

Technical Field

[0001] This utility model relates to the field of coating adjustment technology, specifically a coating viscosity adjustment device for a UV coating line. Background Technology

[0002] As a key raw material for surface coating in UV coating lines, the viscosity of coatings is a crucial parameter that directly affects the fluidity, coating uniformity, drying speed, and the final coating quality and effect.

[0003] Existing regulating devices typically reduce the viscosity of coatings by high-speed stirring to accelerate the mixing effect. However, this requires prolonged stirring to change the viscosity of the coating within the regulating device, leading to a decrease in the regulating efficiency and impacting the production efficiency of the UV coating line.

[0004] For example, CN221015679U discloses a coating viscosity control device, which includes a storage tank for storing coating and a stirring mechanism for stirring the coating in the storage tank. The side wall of the storage tank is provided with a solvent addition pipe and a sensor for detecting the viscosity of the coating in the storage tank. The stirring mechanism includes a rotatable stirring shaft that extends into the storage tank and can reciprocate along the axial direction of the storage tank. The stirring shaft is provided with several stirring moving parts that are equidistantly distributed along the axial direction of the stirring shaft and a mixing plate placed at one end of the stirring shaft that extends into the storage tank. In the above structure, since the viscosity of the coating is adjusted only by stirring, in actual use, it is necessary to stir for a long time to adjust the viscosity of the coating in the device, which leads to a decrease in the adjustment efficiency of the coating and affects the production efficiency of the UV coating line.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a UV coating line paint viscosity adjustment device, including a paint adjustment tank 1 installed on the UV coating line and a heating component for heating the paint. The top of the paint adjustment tank 1 is provided with a feed port 2, and the bottom of the paint adjustment tank 1 is provided with a discharge pipe 3. The surface of the paint adjustment tank 1 is provided with a plurality of connection ports 4 for connecting to the UV coating line. The heating component includes an electric heating tube 5 for heating the paint and an adjustment switch 6 for adjusting the temperature of the electric heating tube 5. The electric heating tube 5 is fixedly connected to the bottom of the inner cavity of the paint adjustment tank 1 by a mounting plate. The adjustment switch 6 is bolted to the outer wall of the paint adjustment tank 1 and is wired to the electric heating tube 5. It also includes a stirring component 7 for stirring the paint.

[0024] When it is necessary to reduce the viscosity of the coating, the electric heating element 5 is activated to heat the coating, thereby changing its viscosity. Then, according to the type of coating in the coating adjustment tank 1, the temperature of the electric heating element 5 is adjusted using the regulating switch 6. Simultaneously, the stirring component 7 is activated to stir and mix the coating in the coating adjustment tank 1, accelerating the adjustment speed. When it is necessary to increase the viscosity of the coating, the electric heating element 5 and the stirring component 7 are turned off. The viscosity of the coating will increase after the temperature drops, and the viscosity will also increase after the coating has stood still. This method shortens the time required for coating viscosity adjustment, improves the coating adjustment efficiency, and reduces the impact on the production efficiency of the UV coating line.

[0025] The electric heating element 5 and the regulating switch 6 mentioned in this embodiment can be connected using a temperature control system in the prior art. Since the temperature control system is a very mature existing technology in the heating field, this utility model does not describe the temperature control system in detail.

[0026] The electric heating element 5 mentioned in this embodiment is connected to the power supply equipment via a power cord.

[0027] The mixing assembly 7 includes a stepper motor 71, which is fixedly mounted on the top of the paint mixing tank 1 via a mounting plate. The output shaft of the stepper motor 71 is keyed to a rotating rod 72, and the rotating rod 72 is rotatably connected to the surface of the paint mixing tank 1 via a bearing. The bottom end of the rotating rod 72 passes through the paint mixing tank 1 and is bolted to a mixing head 73 for mixing the paint. When the stepper motor 71 is started, it drives the rotating rod 72 to rotate, which in turn drives the mixing head 73 at the bottom end to rotate. The mixing head 73 rotates rapidly to shear the paint and mix it.

[0028] The stepper motor 71 mentioned in this embodiment is connected to the power supply equipment via a power cord, and the stepper motor 71 is connected to a control switch via the power cord.

[0029] The stepper motor 71 mentioned in this utility model is a mature existing technology in the mechanical field. This utility model does not provide any further protection or limitation for the stepper motor 71. The stepper motor 71 used in this utility model can be purchased from the market for products with the same function.

[0030] A connecting rod 74 is welded and fixed to the outer surface of the rotating rod 72. A stirring blade 75 is welded and fixed to the other end of the connecting rod 74. When the rotating rod 72 rotates, it drives the connecting rod 74 to rotate, causing the stirring blade 75 at the other end of the connecting rod 74 to move and stir the coating. Several sets of connecting rods 74 are provided. By setting several sets of connecting rods 74, the stirring speed of the coating and the adjustment speed of the coating are improved.

[0031] A support rod 76 is welded and fixed to the outer surface of the rotating rod 72. A scraper 77 for scraping the paint is bolted to the other end of the support rod 76. When the rotating rod 72 rotates, it drives the scraper 77 to rotate through the support rod 76. The rotating scraper 77 scrapes the paint adhering to the inner wall of the paint mixing tank 1, thus avoiding affecting the mixing speed of the paint.

[0032] It also includes a circulation component 8 for circulating the paint. The circulation component 8 includes a paint delivery pump 81, which is fixedly installed on the outer wall of the paint regulating tank 1. The suction pipe 82 of the paint delivery pump 81 is connected to the bottom end of the paint regulating tank 1, and the feed pipe 83 of the paint delivery pump 81 is connected to the top end of the paint regulating tank 1. When the paint delivery pump 81 is started, the paint at the bottom end of the paint regulating tank 1 is extracted through the suction pipe 82, and then the paint at the bottom end is sent to the top end of the paint regulating tank 1 through the feed pipe 83 for re-stirring, forming a circulating stirring and improving the regulating speed of the paint.

[0033] The paint delivery pump 81 mentioned in this utility model is a mature existing technology in the mechanical field. This utility model does not provide further protection or limitations for the paint delivery pump 81. The paint delivery pump 81 used in this utility model can be purchased from the market for products with the same function.

[0034] This embodiment also includes a filter cover bolted to the surface of the extraction pipe 82, and the filter cover is located in the inner cavity of the regulating tank. By setting the filter cover, impurities in the paint can be filtered when the extraction pipe 82 extracts the paint. Then the filtered paint is sent into the paint regulating tank 1 for stirring again. After circulating filtration, the quality of the paint is improved.

[0035] The surface of the paint regulating tank 1 has a slot, and the inner cavity of the slot is equipped with a transparent glass plate 9 for observing the paint level. The transparent glass plate 9 is made of a high-temperature resistant, corrosion resistant, and friction resistant material. The staff can observe the paint level in the paint regulating tank 1 through the transparent glass plate 9 to facilitate timely addition of paint.

[0036] The paint mixing tank 1 includes a tank body 11 and a tank cover 12. The top of the tank body 11 has a threaded hole 13, and the top of the tank cover 12 has a bolt hole 14. The inner cavity of the bolt hole 14 is provided with a self-locking bolt that matches the bolt hole 14. The bottom end of the self-locking bolt passes through the bolt hole 14 and is threadedly connected to the inner cavity of the threaded hole 13. Through the cooperation of the bolt hole 14, the threaded hole 13 and the self-locking bolt, the tank body 11 and the tank cover 12 can be separated and combined, which facilitates the subsequent cleaning and maintenance of the paint mixing tank 1. After the tank cover 12 is combined with the tank body 11, the self-locking bolt is taken out and inserted into the bolt hole 14 and fitted into the inner cavity of the threaded hole 13. The self-locking bolt is turned clockwise to insert into the inner cavity of the threaded hole 13, thus fixing the tank body 11 and the tank cover 12 after combination.

[0037] The lower surface of the can lid 12 is integrally formed with a positioning post 15, and the upper surface of the can body 11 is provided with a positioning hole 16 that matches the positioning post 15. The inner cavity of the positioning hole 16 is engaged with the positioning post 15. Through the engagement of the positioning post 15 and the positioning hole 16, the angle of the can body 11 and the can lid 12 after assembly can be supported, so as to prevent the connection angle of the can body 11 and the can lid 12 from changing due to external forces after connection, thereby improving the stability of the can body 11 and the can lid 12 after connection.

[0038] In practical use: When it is necessary to reduce the viscosity of the coating, first start the electric heating tube 5 to heat the coating in the coating conditioning tank 1, so that the coating temperature rises. Since the viscosity of the coating usually decreases as the temperature rises, the heating process can change the viscosity of the coating. At the same time, according to the type of coating in the coating conditioning tank 1, the heating temperature of the electric heating tube 5 is set by adjusting the switch 6 to adapt to the viscosity change characteristics of different coatings.

[0039] Next, while heating, the stepper motor 71 is started. The stepper motor 71 drives the rotating rod 72 on the output shaft to rotate. The stirring head 73 at the bottom of the rotating rod 72 rotates rapidly to shear and mix the coating. At the same time, the connecting rod 74 on the outer surface of the rotating rod 72 drives the stirring blade 75 to rotate, further increasing the stirring speed and accelerating the uniform mixing of the coating, thereby speeding up the viscosity adjustment of the coating. In addition, the support rod 76 on the rotating rod 72 drives the scraper 77 to rotate, scraping off the coating adhering to the inner wall of the coating adjustment tank 1, avoiding the coating sticking to the wall and affecting the mixing efficiency and viscosity adjustment effect.

[0040] Subsequently, while stirring, the paint delivery pump 81 is started, and the paint at the bottom of the paint conditioning tank 1 is extracted through the extraction pipe 82 and then sent back to the top through the feeding pipe 83 to form a circulating stirring. This process can not only make the paint more evenly mixed in the circulation, but also accelerate the temperature transfer and viscosity adjustment, and improve the paint conditioning speed.

[0041] When the viscosity of the coating increases, the electric heating element 5, the circulation component 8, and the stirring component 7 are turned off. As heating stops, the coating temperature gradually decreases, and its viscosity increases accordingly. Simultaneously, after the coating settles, the intermolecular interactions strengthen, further increasing the viscosity. This method achieves viscosity adjustment, shortens the time required for viscosity adjustment, improves the adjustment efficiency, and reduces the impact on the production efficiency of the UV coating line.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
