Description

Technical Field

[0001] The invention relates to the technical field of roller sand making machines, in particular to a nail-studded rolling roller structure of a sand making machine. Background Art

[0002] A roller sand making machine usually includes a fixed roller and a movable roller. The material is fed from above the two rollers, continuously brought between the rollers by the squeezing roller, and discharged from the bottom of the machine with an ideal particle size. The stone is crushed into sand by the relative movement of the two rollers. In the Chinese patent literature, patent number CN202021220681X was authorized and announced on April 13, 2021. The application includes a vertical frame, a first rolling roller, a second rolling roller and a drive motor. A rolling channel is formed between the first rolling roller and the second rolling roller. The first rolling roller is rotatably connected to the frame, and the drive motor is connected to the frame. The drive motor is used to drive the first rolling roller to rotate. The frame is provided with a plurality of support legs, and the support legs include a bottom plate, a lifting plate, a top plate and a column arranged in sequence from bottom to top, and a positioning ring is provided on the bottom plate. In order to improve the stone crushing effect, column nails are embedded on the roller sleeve (surface layer of the rolling roller) of the rolling roller. The embedding depth of the existing column nails is the same, so the roots of the column nails are located on the same layer. The roots of the column nails are located on the same layer, which easily causes the roller skin to break during use. Summary of the invention

[0003] The invention aims to provide a sand making machine nailed rolling roller structure with a roller skin that is not easily broken, thereby solving the problem that the roller skin of the existing rolling rollers inlaid with column nails is easily broken.

[0004] The above technical problems are solved by the following technical solutions: A nailed rolling roller structure of a sand making machine, comprising a roller sleeve and a first column nail, characterized in that the cross section of the first column nail is circular, the surface of the roller sleeve is provided with a plurality of rows of the first column nails distributed along the circumference of the roller sleeve, the first column nails in the same row of the first column nails are distributed along the axial direction of the roller sleeve, and the first column nails are embedded in the roller sleeve; the depth of one of the two adjacent first column nails in the same row of the first column nails embedded in the roller sleeve is greater than the depth of the other first column nail embedded in the roller sleeve, the first column nail with a large embedding depth is called a deep-embedded first column nail, and the first column nail with a shallow embedding depth is called a shallow-embedded first column nail. The embedding depths of the first column nails are different and staggered, which can prevent the first column nails from being subjected to stress at the same layer (cross section) at the root layer, causing the roller skin to fall off. Because the roller is circular, the distance between the exposed parts of the first column nails is small, and even smaller at the root, so the stress is staggered with different depths, making the roller skin base more durable.

[0005] Preferably, the first studs in two adjacent rows of first studs are staggered one by one along the circumference of the roller sleeve. When the spacing between the first studs in two adjacent rows remains unchanged, the distance between the adjacent first studs in the two adjacent rows of first studs can be large, thereby better preventing the roller skin from falling off.

[0006] Preferably, the line connecting the line segments with the adjacent deep-set first studs as endpoints along the circumference of the roller sleeve is the return line, and the line connecting the line segments with the adjacent shallow-set first studs as endpoints along the circumference of the roller sleeve is the return line. The roots of the deep-set first studs and the shallow-set first studs can be staggered, making it more difficult for the roller skin to fall off.

[0007] Preferably, the distance between the first studs in two adjacent rows of first studs along the axial direction of the roller sleeve is half of the distance between the two adjacent first studs in the same row; the distance between the edge first studs in the row of first studs close to the roller sleeve end face and the roller sleeve end face is less than half and more than one quarter of the distance between the two adjacent first studs in the same row, and the outer side of the edge first stud in the row of first studs far from the roller sleeve end face is inlaid with a second stud, and the second stud and the first stud in the row of first studs far from the roller sleeve end face are located on the same straight line extending along the roller sleeve, and the diameter of the first stud is greater than the diameter of the second stud. This can prevent the stones at the end of the roller sleeve from turning outward and damaging the roller sleeve during the rolling process.

[0008] Preferably, the outer edge of the second stud and the outer side of the first stud adjacent to the second stud along the circumference of the roller sleeve are located on the same plane perpendicular to the axis of the roller sleeve, which can more reliably prevent the stone from turning outward and damaging the end of the roller sleeve.

[0009] Preferably, the cross section of the second stud is circular, and the radius of the second stud is half of the radius of the first stud, so as to extend the distance between the second stud and the first stud in the adjacent row, and better prevent the roller skin from falling off.

[0010] Preferably, each first stud except the first stud closest to the end of the roller sleeve is surrounded by six first studs, so that the force on the first stud during rolling can be reduced, and the first stud can be more reliably grasped for crushing.

[0011] Preferably, when the surrounded first column nail is a deep-set first column nail, only two of the six first column nails surrounding the outer periphery of the surrounded first column nail are deep-set first column nails; when the surrounded first column nail is a shallow-set first column nail, only two of the six first column nails surrounding the outer periphery of the surrounded first column nail are shallow-set first column nails. This can better prevent the roller skin of the house from falling off.

[0012] Preferably, when the roller sleeve is unfolded into a plane, the six first column nails surrounding the periphery of the same first column nail are located at the six corners of the same regular hexagon; the first column nails of two adjacent rows, one row of column nails located at the edge of one end of the roller are deeply set first column nails, and the first column nails of the other row of column nails located at the edge of one end of the roller are shallowly set first column nails. This can better prevent the roller skin from falling off.

[0013] Preferably, the hardness of the roller sleeve is greater than that of the first stud. When the first stud is inserted, the first stud is squeezed and deformed and inserted together with the roller sleeve, so that the deformation of the roller sleeve caused by replacing the first stud is small, and the small deformation makes the roller sleeve still usable when the first stud is replaced multiple times.

[0014] The beneficial effect of the present invention is that the first column nails are embedded at different depths and at staggered intervals, which can effectively prevent the roller skin from cracking during use. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1 and Figure 2A nailed roller structure for a sand making machine comprises a roller sleeve 1. The surface of the roller sleeve is provided with a plurality of rows of first column nails 3 uniformly distributed along the circumference of the roller sleeve. The cross section of the first column nail is circular. The first column nails in the same row of first column nails are uniformly distributed along the axial direction of the roller sleeve, and the first column nails are embedded in the roller sleeve; the depth of one of the two adjacent first column nails in the same row of first column nails is greater than the depth of the other first column nail embedded in the roller sleeve, and the first column nail with a large embedding depth is called a deep-embedded first column nail 4, and the first column nail with a shallow embedding depth is called a shallow-embedded first column nail 5. The embedding depths of the first column nails are different and staggered, which can prevent the first column nails from being stressed at the same layer (cross section) at the root layer, causing the roller skin to fall off. Because the roller is circular, the distance between the exposed parts of the first column nails is small in itself, and even smaller at the root, so the different depths and shallows are staggered to bear stress, making the roller skin base more durable. The first column nails in two adjacent rows of first column nails are staggered one by one along the axial direction of the roller sleeve. The line 6 connecting the line segments with the adjacent deep-set first studs along the circumference of the roller sleeve as endpoints is the return line, and the line 7 connecting the line segments with the adjacent shallow-set first studs along the circumference of the roller sleeve as endpoints is the return line. The distance between the first studs in two adjacent rows of first studs along the axial direction of the roller sleeve is half of the spacing between the two adjacent first studs in the same row; in the two adjacent rows of first studs, the distance between the edge first stud 8 in the row of first studs close to the end face of the roller sleeve and the edge first stud 9 in the row of first studs far from the end face of the roller sleeve is less than half and more than one-quarter of the spacing between the two adjacent first studs in the same row, and the second stud 10 is inlaid on the outer side of the edge first stud 9 in the row of first studs far from the end face of the roller sleeve, and the second stud and the first stud in the row of first studs far from the end face of the roller sleeve are located on the same straight line extending along the roller sleeve. The cross section of the second stud is circular. The diameter of the first stud is larger than the diameter of the second stud. The radius of the second column nail is half of the radius of the first column nail. The outer edge of the second column nail and the outer side of the first column nail adjacent to the second column nail along the circumference of the roller sleeve are located on the same plane perpendicular to the axis of the roller sleeve. Each first column nail except the first column nail closest to the end of the roller sleeve is surrounded by six first column nails. When the surrounded first column nail is a deep-set first column nail, only two of the six first column nails surrounding the outer periphery of the surrounded first column nail are deep-set first column nails; when the surrounded first column nail is a shallow-set first column nail, only two of the six first column nails surrounding the outer periphery of the surrounded first column nail are shallow-set first column nails. When the roller sleeve is unfolded into a plane, the six first column nails surrounding the outer periphery of the same first column nail are located at the six corners of the same regular hexagon; in two adjacent rows of the first column nails, the first column nails of one row located at the edge of one end of the roller are deep-set first column nails, and the first column nails of the other row located at the edge of one end of the roller are shallow-set first column nails. The hardness of the roller sleeve is greater than the hardness of the first column nail.
