Description

Technical Field

[0001] The utility model relates to the technical field of roller machines, in particular to a pressure-adjustable roller machine. Background Art

[0002] The double roller mill is reliable, easy to maintain, has low operating costs, and has an adjustable discharge size. It can be widely used in industries such as cement, metallurgy, chemical industry, electric power, and coal to process brittle and tough materials.

[0003] In order to control the diameter of the crushed stone particles during use, the existing roller mill needs to adjust the spacing between the two rollers in the roller mill. When the spacing between the two rollers increases, the diameter of the crushed stone particles becomes larger; when the spacing between the two rollers decreases, the diameter of the crushed stone particles becomes smaller. However, the two rollers are often rigidly mounted. When the roller position is adjusted, the running equipment needs to stop. Moreover, if a material with a greater strength than the rollers is accidentally placed, the rollers cannot be flexibly buffered due to their fixed position, which can easily cause damage to the rollers and affect the use of the equipment. Based on this, the present application proposes a pressure-adjustable roller mill to solve the above problems. Utility Model Content

[0021] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] like Figures 1 to 5 As shown, a pressure-adjustable roller machine includes two parallel supported seats 1, which are rectangular frame-shaped as a whole. Assembly seats 6 are slidably installed at both ends of the two supported seats 1, and rollers 8 are rotatably installed between the two groups of assembly seats 6. Threaded rods 2 are threadedly installed at both ends of the outside of the two supported seats 1, and a top seat 3 is installed at one end of the inner side. Springs 4 are installed on the outside of the four top seats 3, and slides 5 are installed on the outside of the four springs 4. One side of the outer surface of the four slides 5 is concave to form an installation groove 15, and pressure sensors 7 are installed inside the four installation grooves 15, which are located between the slides 5 and the assembly seats 6.

[0023] As an optional technical solution of the present invention, short slots 11 are provided at both ends of the top surfaces of the two support seats 1, and nut seats 10 are installed at both ends of the inside of the two support seats 1, which are threadedly matched with the threaded rod 2. A handwheel 9 is installed at one end of the outside of the four threaded rods 2. Due to the installation of the nut seat 10, the threaded match between the threaded rod 2 and the support seat 1 can be achieved.

[0024] As an optional technical solution of the present invention, one side of the outer surface of the four top seats 3 and the slide plate 5 is convexly formed with a convex clip, which engages with the spring 4 to fix the position of the spring 4 and prevent the spring 4 from collapsing.

[0025] As an optional technical solution of the present invention, the four skateboards 5 are all H-shaped, and rollers 14 are rotatably installed inside both ends of the skateboards. The multiple rollers 14 roll along the inner walls of the two support seats 1 respectively. The presence of the rollers 14 can reduce the wear between the skateboard 5 and the support seat 1.

Threaded rods 2 are threadedly installed at both ends of the exterior of the two support seats 1, and a top seat 3 is installed at one end located on the inner side. A slide plate 5 is slidably installed inside the two support seats 1, and a spring 4 is installed between it and the top seat 3. By rotating the threaded rod 2, the position of the slide plate 5 can be adjusted, and then the position of the assembly seat 6 can be adjusted to change the spacing between the two pairs of rollers 8. At the same time, the spring 4 can buffer the two In order to reduce the impact on the rollers 8 and reduce the damage to the rollers 8 caused by larger collisions, a pressure sensor 7 is installed between the slide 5 and the assembly seat 6 to detect the pressure between the two and remind the staff of sudden changes in pressure between the two. The overall shape of the slide 5 is H-shaped, and rollers 14 are rotatably installed inside both ends of the slide 5, which can roll along the inner wall of the support seat 1 to reduce the wear between the two and make the slide 5 slide more smoothly. A plurality of ball grooves 12 are provided on the outside of the assembly seat 6, and balls 13 are rotatably installed inside the ball grooves 12. The balls 13 can roll on the inner wall of the support seat 1, which can reduce the wear of the assembly seat 6 during sliding.
