Description

Technical Field

[0001] The utility model relates to the technical field of sand making equipment, in particular to an anti-slip and anti-loosening pressure roller. Background Art

[0002] In the prior art, the pressure roller of a double-roller sand making machine is usually of split type, consisting of a roller skin, a wheel hub and a roller shaft, so that the roller skin can be replaced when it is worn, thereby reducing the cost of use. Usually, for the convenience of installation, there will be some gaps between the roller skin and the wheel hub due to the impact of the crushing process, especially for large-diameter roller skins, where there is no gap after the contact surface is tightened during installation. However, during use, due to the high power and impact, the friction between the two rollers is also greater, and the pressure roller will become loose after a period of use, causing the double-roller sand making machine to fail to work normally.

[0003] The Chinese patent (patent application number CN202122511241.0) discloses a "roll crusher for preventing roller dislocation", which includes a power device, a frame 10, a pressure regulating device 9 and a roller mechanism, and a material discharge chute 11 is arranged on the upper part of the frame 10; A, convex rings 17 are arranged on both sides of the cylinder surface of the sliding roller 8, and an annular groove 16 is arranged in the middle; B, an annular concave platform 18 is arranged on both sides of the cylinder surface of the fixed roller 13, and an annular boss 19 is arranged in the middle; C, after the sliding roller 8 and the fixed roller 13 are installed, the annular groove 16 and the annular boss 19 form a chimeric shape. It has the characteristics of preventing roller dislocation, extending the service life of rollers, and improving the efficiency of equipment use. It can be used to prepare sand for construction using materials such as sandstone, pebbles, etc., and can also be used for pre-grinding of grinding systems; it can be widely used in construction, building materials, mining and other fields.

[0004] Another Chinese patent (patent application number CN201420369038.1) discloses "an anti-slip pressure roller", which comprises a roller (1) and a wheel hub (4), wherein the roller (1) is mounted on the wheel hub (4); one or more axial convex strips (2) are provided on the inner wall of the roller (1); and grooves matching the axial convex strips (2) are provided on the outer cylindrical surface of the wheel hub (4); the roller has the characteristics of easy maintenance and no slipping, and can be used in conjunction with a double-roller sand making machine to prepare sand for construction using materials such as sandstone, pebbles, etc., and can also be used for pre-grinding of a grinding system; the roller can be widely used in the fields of construction, building materials, mining, etc.

[0005] There is also a Chinese patent (patent application number 201822171982.7) that discloses "a roller for a roller machine that is easily disassembled", which includes a roller body, a roller skin and a shaft. The roller body is sleeved on the shaft and rotates driven by the shaft. The roller skin is installed on the outer layer of the roller body. There are at least two roller skins. At least two rows of roller skin mounting bayonet holes are arranged in parallel on the surface of the roller body. A row of mounting clips that cooperate with the roller skin mounting bayonet holes are arranged at the bottom of the roller skin. The mounting clips are embedded in the roller skin mounting bayonet holes. A fastening pile is provided on the outer edge of the outermost mounting clip to ensure that the mounting clips are fixedly connected to the roller skin mounting bayonet holes. The advantage of this utility model is that after the roller skin is severely worn, there is no need to bring the roller machine back to the workshop to replace the roller skin. The roller skin replacement can be completed at the construction site, which greatly improves work efficiency and shortens construction period.

[0006] There is also a "composite roller structure of a double-roll crusher" disclosed in a Chinese patent (patent application number 202120180249.0). The roller includes a roller and a roller shaft. The roller is mounted on the roller shaft. The roller is a hollow structure. The roller includes an inner ring, an outer ring, a left plate and a right plate. The roller is filled with concrete. The inner sides of the inner ring, the outer ring, the left plate and the right plate are respectively fixed with anchor nails. The utility model increases the heavyweight moment of inertia of the roller of the double-roll crusher, increases the useful work of the roller, and increases the strength of the roller. The crushing effect of the double-roll crusher is significantly improved, the cost is low, and the structure is simple. Summary of the invention

DETAILED DESCRIPTION

[0022] The following is a further description of the present invention in conjunction with the accompanying drawings and embodiments. The following description is in the form of examples, but the protection scope of the present invention should not be limited thereto.

[0023] Example:

[0024] The anti-skid and anti-loosening pressure roller of this embodiment is composed of a roller skin 1, a wheel hub, a pair of left and right pressure rings 4, more than two pairs of left and right pressure ring fixing bolts 3, curing glue 8 and a filling pad 2.

[0025] The wheel hub is composed of an outer cylinder 12 , an inner cylinder 11 and a rib plate 9 , and the outer cylinder 12 and the inner cylinder 11 are connected by the rib plate 9 .

[0026] The outer cylinder 12 is cylindrical and symmetrical on the left and right; steps for clamping the left and right pressure rings 4 are respectively provided at the left and right ends of its outer cylinder; a curing glue filling ring groove for filling the curing glue 8 is provided in the middle of its outer cylinder; and an accommodating ring groove 6 for accommodating the ends of the left and right pressure ring fixing bolts 3 is also provided on the outer cylinder between the curing glue filling ring groove and the step; a flange is formed on the outer cylinder between the bottom surface of the step and the accommodating ring groove 6, and a plurality of (30 in this example) screw holes for screwing the left and right pressure ring fixing bolts 3 are evenly distributed on the flange; a glue retaining ring cylinder 5 for preventing glue leakage during glue pouring is also provided at the outer ring of the accommodating ring groove 6; on the outer cylinder of the outer cylinder 12, four (or two, three, five or more) axial convex grooves 17 in the shape of a "concave" are also designed to match the roller skin 1.

[0027] The inner cylinder 11 is also cylindrical, and its inner hole is the shaft hole 10 ; a shaft hole keyway 16 is provided on the hole wall of the shaft hole 10 .

[0028] The rib plate 9 supports the outer cylinder 12 and reduces the weight and material consumption, and a plurality of rib plate holes 14 (eight in this example) are provided on the rib plate.

[0029] The left and right pressure rings 4 are an annular sleeve, whose inner wall is an inner cylindrical surface, and the outer wall is a conical surface with a small inner diameter and a large outer diameter (taking the left and right pressure rings 4 used at the left end as an example, that is, the left end has a large diameter and the right end has a small diameter), and is provided with a plurality of (30 in this example) axial holes for installing the left and right pressure ring fixing bolts 3.

[0030] The roller skin 1 is mounted on the outer cylinder 12, which is cylindrical, and an annular groove is designed in its inner hole. The hole walls at both ends of the inner hole are inner conical surfaces with a larger outer surface and a smaller inner surface (used to match the outer walls of the left and right pressure rings 4). In the annular groove of the roller skin 1, there is also one (or two, three, four or more) convex annular radial reinforcing rib 7 and four (or two, three, five or more) axial reinforcing ribs 13. The radial reinforcing rib 7 and the axial reinforcing rib 13 are connected as a whole to enhance the rigidity of the roller skin 1; the axial reinforcing rib 13 is embedded in the "concave" shaped axial convex groove 17 to prevent radial movement between the roller skin 1 and the outer cylinder 12.

[0031] Two (or one, three or more) glue injection holes 15 are provided between the inner hole wall of the roller skin 1 and the outer walls of the left and right pressure rings 4 for injecting the curing glue 8 .

[0032] The filling pad 2 (cement block is used in this example, and other curable and low-cost filling materials can also be used) is filled on the bottom wall of the annular groove of the roller skin 1, and the curing glue 8 (low-viscosity epoxy resin glue is used in this example, and other curing glue can also be used) is poured through the glue injection hole 15 between the filling pad 2 and the curing glue filling annular groove of the outer cylinder 12. The thickness of the filling pad 2 is less than the height of the radial reinforcing rib 7.

[0033] During use of the anti-slip and anti-loosening pressure roller of this embodiment, the axial reinforcing ribs 13 in the annular groove of the roller skin 1 are embedded in the "concave"-shaped axial convex grooves 17 of the outer cylinder 12, thereby preventing radial movement between the roller skin 1 and the outer cylinder 12. At the same time, since the thickness of the filling pad 2 is less than the height of the radial reinforcing ribs 7, the curing glue 8 poured between the annular groove of the roller skin 1 and the curing glue filling annular groove of the outer cylinder 12 can fully wrap the radial reinforcing ribs 7, thereby preventing looseness and avoiding the occurrence of axial movement.

[0034] The anti-skid and anti-loosening pressure roller of the utility model is applied to a double-roller sand making machine and can be used for ore dressing, powder making or preparing sand for construction using various non-metallic ores, mine tailings, industrial waste residues and other raw materials that meet the sand making requirements.
