Problems solved by technology

[0003] The three-roller machine is mainly used for the grinding of high-viscosity micropowder. The material of the general-purpose three-roller machine is directly fed from the middle roller and the rear roller, which will cause the material on the middle roller and the rear roller at the position of the feed inlet to be redundant with other parts. The amount of grinding is higher than that of other parts, and uneven grinding on the roller shaft will cause unevenness on the surface of the roller shaft, which will seriously affect the effect of subsequent grinding

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0022] exist figure 1 In the shown embodiment, the three-roll machine comprises a rear roll 1, a middle roll 2, a front roll 3, a frame 4, and a stopper device 5, and the stopper device 5 includes a stop bar 51, a connecting assembly 52, and the stop bar 51 is a straight strip with an inverted V-shaped cross section, located directly above the approach line of the rear roller 1 and the middle roller 2, and parallel to the respective axes of the three rollers. On the outer cylindrical surface of the roller 1 and the middle roller 2 , the connecting assembly 52 is connected to both ends of the bar 51 to fix the bar 51 on the frame 4 .

[0023] Such as figure 2 As shown, the blocking device 5 is installed above the rear roller 1 and the middle roller 2, parallel to and close to the outer cylindrical surface of the rear roller 1 and the middle roller 2, and the mat...

Abstract

The invention provides a three-roller machine, belonging to the technical field of machinery, comprising a rear roller, a middle roller, a front roller, a frame, and a stopper device, wherein the stopper device comprises a barrier strip and a connection assembly, the barrier strip is a straight strip with an inverted V-shaped cross section and is arranged above a line close to the rear roller and the middle roller and parallelly to the respective axis of each roller, the two extended V-shaped edges of the barrier strip are close to the outer cylindrical surfaces of the rear roller and the middle roller, and the connection assembly is connected with the two ends of the barrier strip to fix the barrier strip on the frame. According to the invention, materials can uniformly flow in the rear roller and the middle roller, and various metal objects and hard sundries are effectively prevented from entering between the running rear roller and the middle roller.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a three-roller machine equipped with a stopper device. Background technique [0002] The three-roll machine has three rollers installed on the iron frame, and the centers are in a straight line. Can be installed horizontally, or slightly inclined. The grinding effect is achieved by the mutual extrusion of the surfaces of the three horizontal rollers and the friction at different speeds. The steel drum can be hollow and cooled by water. The material is fed between the middle roll and the rear roll. Since the rotation directions of the three drums are different (the rotation speed increases sequentially from the back to the front), a good grinding effect is produced. After the material is ground, it is scraped off by the scraper installed in front of the front roller. Three-roll mill is the most effective grinding and dispersing equipment for high-viscosity materials. Main...
