Problems solved by technology

[0002] my country is the manufacturing center of the world, and it needs to consume a large amount of coatings every year. Most of the existing coatings are prepared liquid types. The cost of transportation must be high in barrels. Restricted by factors, powder coatings have developed rapidly in recent years. It has the advantages of low bagging cost, small space occupied by storage and transportation, small proportion compared with unit dosage, no volume dilution and no climate influence, avoiding losses due to freezing, and further reducing Sto...

Abstract

The invention discloses a longitudinal wave type tabletting and crushing machine for powder coatings. The longitudinal wave type tabletting and crushing machine comprises a tabletting part, a crushing part and a conveying belt. Two primary compression rollers are hollow round rollers; the gap between the two primary compression rollers is 1.5 mm to 2.5 mm; the axes of the two primary compression rollers are in parallel; and shaft rods at the two ends of each primary compression roller are connected with a machine frame. Two secondary compression rollers are hollow wave surface rollers; the axes of the two secondary compression rollers are in parallel; and shaft rods at the two ends of each secondary compression roller are connected with the machine frame. Annular up-and-down wave crests and troughs are arranged on the surfaces of the wave surface rollers. The shaft rods at one ends of the secondary compression rollers are connected through a second synchronous gear and rotate at the same speed; the wave crests of one wave surface roller are aligned at the wave troughs of the other wave surface roller; and the gap between the wave crest face and the wave trough face which are opposite is 1 mm to 1.5 mm. Long teeth and short teeth which are distributed in the circumferential direction are arrayed on the surface of a crushing roller in the axial direction at intervals, and the radius of the circle where the edges of the long teeth are located is larger than the radius of the circle where the edges of the short teeth are located. Overturning can be conducted easily during powder grinding so that multidirectional grinding can be achieved, accumulation is not likely to happen, the efficiency is improved, the structure is simple, implementation is easy, and the longitudinal wave type tabletting and crushing machine is suitable for application and popularization.

Example Embodiment

[0012] Examples of the invention Figure 1 to 2 As shown, the powder coating longitudinal wave tablet crusher includes a tableting part, a crushing part and a conveyor belt 1. The tableting part is provided at the input end of the conveyor belt, and the tableting part is provided with a first-stage pressing roller 2 and a second-stage The axis of the pressure roller, the primary pressure roller and the secondary pressure roller are perpendicular to the conveying direction of the conveyor belt; the primary pressure roller is a hollow circle with two parallel axes with a gap of 1.5 mm to 2.5 mm. Roll, one end shaft of the primary pressure roller is connected by the first synchronous gear 3 to rotate at a constant speed, which can press the molten mixture into a sheet of 1.5 mm to 2.5 mm; the secondary pressure roller is two parallel shafts at both ends The hollow wave surface roller 4 is connected to the frame. The axially spaced array of the wave surface roller has undulating annular wave crests and wave troughs. One end shaft of the secondary pressure roller is connected to rotate at a constant speed through the second synchronous gear 5. One of the wave crests of the wave surface roller It is aligned with a wave trough of the other wave surface roller, and the gap between the opposite wave crest surface and wave trough surface is 1 mm to 1.5 mm. The second-level pressure roller corrugated roller further presses the sheet pressed by the first-level pressure roller into a pressure with longitudinal waves. The pieces are corrugated; the crushing part is set on the output side of the conveyor belt, with two parallel shafts at both ends of the crushing roller 6 connected to the frame, and one end of the two crushing rollers is connected by a third synchronous gear 7 to rotate at a constant speed , The surface of the crushing roller is arranged in an axially spaced array with long teeth 8 and short teeth 9 distributed in the circumferential direction. The radius of the outer edge of the long tooth is larger than the radius of the outer edge of the short tooth; two crushing rollers are close to the side, one crushing roller The long teeth of the other crushing roller extend into the short teeth between the two circumferential long teeth; the primary pressure roller, the secondary pressure roller, the crushing roller and the conveyor belt drive wheel 10 are respectively connected with a power source, which can be through a transmission mechanism It can share the same one, or can be set separately. The angle of the axis line of the primary pressure roller and the axis of the secondary pressure roller is 15 to 30 degrees. There is a guide roller 11 between the primary pressure roller and the secondary pressure roller to guide Sheet conveying direction: A sheet pressing roller 12 is arranged between the secondary pressing roller and the conveying belt to increase the friction between the sheet and the conveying belt and improve the conveying effect. The press sheet with longitudinal waves of the present invention has a small contact area with the conveyor belt under the action of the undulating longitudinal waves when conveyed on the conveyor belt, avoiding large-area adhesion, and the lower ventilation effect is good, and the cooling is fast, which can effectively reduce the length of the conveyor belt. Occupying space, the compressed tablets with longitudinal waves are shredded by the long teeth of the crushing roller and then broken by the short teeth. The curved tablets have high stiffness and are easy to break, and the crushed particles are small and uniform. The particles obtained by crushing are not flat and have arcs. , It is loose and easy to move when piled up, it is easy to turn and grind in multiple directions when grinding, it is not easy to deposit, the efficiency is improved, the structure is simple and easy to implement, and it is suitable for popularization and application.
[0013] When the invention is implemented, a water cooling mechanism can be connected to the primary pressure roller, the secondary pressure roller, and the driving wheel of the conveyor belt to improve the cooling effect.
[0014] In summary, the above are only preferred embodiments of the present invention, and all equivalent modifications and additions in the prior art made in accordance with the present application are regarded as the technical scope of the present invention.
