Description

Technical Field

[0001] The utility model belongs to the technical field of powder coating production, in particular to a tablet press for producing thermosetting powder coating. Background Art

[0002] Thermosetting powder coating is a special coating, mainly composed of epoxy resin, polyester, acrylic, polyurethane and other resins with hardener, additives and pigments. This coating does not require the addition of solvents during the production process, so it has extremely high environmental performance. In the production process of thermosetting powder coating, the thermosetting powder coating needs to be pressed into sheets, and a tablet press is used at this time.

[0003] Existing powder coating tabletting machines generally use rollers to press sheets. However, since the spacing between the rollers cannot be adjusted, it is impossible to press out sheet coatings of different thicknesses according to different processing requirements. In addition, after the powder coating is extruded into sheets, it still has a high temperature, which is not conducive to subsequent processing. Therefore, the powder coating needs to be cooled. The traditional cooling method is to increase the heat exchange time between the powder coating and the air by lengthening the distance of the conveying device or controlling the speed of the conveying device, but this is inefficient and has a poor cooling effect.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a tablet press for producing thermosetting powder coatings, such as Figure 1-4 As shown, the tablet press for producing thermosetting powder coatings comprises: a base plate 1, on the top of which two first brackets 4 and two second brackets 20 are fixedly mounted; a plurality of supporting legs 2 fixedly mounted on the top of the base plate 1, on which the same conveyor 3 is fixedly mounted, and on which a conveyor belt is arranged; a frame plate 5 welded to the top of the two first brackets 4; a water tank 6 fixedly mounted on the top of the two second brackets 20 for storing coolant; a tablet pressing mechanism mounted on the frame plate 5 for extruding thermosetting powder coatings; and a cooling mechanism mounted on the water tank 6 for cooling the powder coatings.

[0022] In this embodiment, when in use, the thermosetting powder coating to be pressed into a sheet is put into the sheet pressing mechanism from above, so that the two pressing rollers 11 in the sheet pressing mechanism squeeze the powder coating into sheets. Since the spacing between the two pressing rollers 11 is adjustable, sheet coatings of different thicknesses can be pressed out according to different processing requirements, and the use effect is better. The sheet-shaped coating will then fall onto the conveyor belt of the conveyor 3, so that the conveyor belt can drive the sheet coating to move toward the cooling mechanism, so that the cooling mechanism can cool the sheet coating by discharging low-temperature gas. Compared with the traditional cooling method, the cooling effect can be effectively improved, and the working efficiency is better.

[0023] In a further preferred embodiment of the utility model, the pressing mechanism includes: two sliding rods 7 slidably mounted on the frame plate 5; two screw rods 8 threadedly mounted on the frame plate 5, and the ends of the two screw rods 8 close to each other are rotatably mounted with a U-shaped plate 9, and the sides of the two U-shaped plates 9 away from each other are respectively fixedly connected to the ends of the two sliding rods 7 close to each other; two rotating shafts 10 respectively rotatably mounted on the two U-shaped plates 9, and the two rotating shafts 10 are fixedly sleeved with a pressure roller 11; two motors 12 respectively fixedly mounted on the two U-shaped plates 9, and the output shafts of the two motors 12 are fixedly mounted with a first gear 13; two second gears 14 respectively fixedly sleeved on the two rotating shafts 10, and the two second gears 14 are respectively meshed with the two first gears 13.

[0024] In this embodiment, the sheeting mechanism is used to extrude thermosetting powder coatings. Before extrusion, the spacing between the two pressing rollers 11 needs to be adjusted according to the processing requirements. During adjustment, the two screws 8 are rotated, and the two screws 8 will drive the two U-shaped plates 9 to move away from or closer to each other. The two U-shaped plates 9 will drive the two pressing rollers 11 to move away from or closer to each other through the two rotating shafts 10, thereby completing the adjustment of the spacing between the two pressing rollers 11. After the adjustment is completed, the thermosetting powder coating can be extruded. During extrusion, the two motors 12 are started, and the two motors 12 will drive the two first gears 13 to rotate. The two first gears 13 will drive the two rotating shafts 10 to rotate through the two second gears 14. The two rotating shafts 10 will drive the two pressing rollers 11 to rotate, so that the two pressing rollers 11 can extrude the thermosetting powder coating and press the coating into sheets.

[0025] In a further preferred embodiment of the utility model, the cooling mechanism includes: a cavity 15 opened on the water tank 6; a plurality of exhaust pipes 16 fixedly installed at the bottom of the water tank 6, the plurality of exhaust pipes 16 are connected to the interior of the cavity 15, and the bottom ends of the plurality of exhaust pipes 16 are provided with air diffusers 17; a plurality of cooling pipes 18 fixedly installed on the water tank 6, one end of the plurality of cooling pipes 18 extends to the outside of the water tank 6, and the other end of the plurality of cooling pipes 18 extends to the inside of the cavity 15; a plurality of fans 19 fixedly installed on the top of the water tank 6, and the exhaust ends of the plurality of fans 19 are respectively fixedly connected to one end of the plurality of cooling pipes 18.

[0026] In this embodiment, the cooling mechanism is used to cool the powder coating. When working, the fan 19 will transmit the gas to the cooling pipe 18. Since the cooling pipe 18 is immersed in the coolant, the gas entering the cooling pipe 18 will be fully cooled, and then it will be transmitted from one end of the cooling pipe 18 to the cavity 15. The cavity 15 will transmit the gas to multiple exhaust pipes 16, and finally discharged from multiple air expansion hoods 17, so as to cool down the flaky coating moved by the conveyor 3 below, and the cooling effect is better.

[0027] In a further preferred embodiment of the present invention, a turntable is fixedly mounted on one end of the two screw rods 8 away from each other, and a handle is rotatably mounted on one side of the two turntables away from each other.

[0034] In this embodiment, multiple filters can reduce the amount of dust in the air that enters the interior of the multiple fans 19. The multiple stainless steel filters have good corrosion resistance, will not rust, and have good durability.

[0035] To sum up, compared with the related art, the present solution can extrude thermosetting powder coating into sheets through a sheeting mechanism. Since the spacing between the two pressing rollers 11 in the sheeting mechanism can be adjusted, sheet coatings of different thicknesses can be pressed out according to different processing requirements, and the use effect is good. The powder coating pressed into sheets can be conveyed by the conveyor 3, so that the powder coating can be cooled by the cooling mechanism. Since the cooling mechanism can cool the sheet coating by discharging low-temperature gas, compared with the traditional cooling method, the cooling effect can be effectively improved, and the work efficiency is good. The coordinated use of the discharge pipe and the valve can facilitate the operator to discharge the coolant in the water tank 6, and the coolant in the water tank 6 can be conveniently replaced. The water filling pipe can facilitate the operator to add coolant to the water tank 6. The water filling pipe can be shielded by the cover body to prevent dust and impurities from entering the water tank 6.
