Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a double-sand belt grinder for a super-wide plate surface. Background Art

[0002] Sanding belt machines can be divided into several categories, including desktop sanding belt machines, vertical sanding belt machines, hand-push sanding belt machines, and dust removal sanding belt machines.

[0003] Definition of ultra-wide steel plate: Ultra-wide steel plate is divided into cold-rolled and hot-rolled. Generally speaking, for cold-rolled steel plate, a single plate with a width of more than 1800mm can be called an ultra-wide plate, and for hot-rolled steel plate, a single plate with a width of more than 2200mm can be called an ultra-wide plate.

[0004] Manual grinding of ultra-wide plates is labor-intensive, time-consuming and labor-intensive, with a harsh operating environment, poor weld grinding quality, and inconsistent metal plate textures. If automatic grinding is used for processing, due to the long processing distance, it is impossible to guide and correct the deviation of the grinding head in time, which is not conducive to improving the grinding quality. Utility Model Content

[0005] The utility model aims to provide a double-belt grinder for super-wide plate surfaces, so as to solve the technical problems of high labor intensity, time-consuming and labor-intensive manual grinding, poor operating environment, poor weld grinding quality, and inconsistent metal plate texture.

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

[0026] Reference Manual Attached Figure 1-Figure 5 As shown, a double-belt sanding machine for ultra-wide plate surface comprises:

[0027] A frame 1, on which a lateral moving mechanism 2 and a longitudinal moving mechanism 3 adapted to the guide rail are connected; wherein the longitudinal moving mechanism 3 comprises a rotating tooth connected to a travel motor, the outer wall of the rotating tooth meshes with a gear plate 4 fixed to the frame 1, and the longitudinal moving mechanism 3 is used to drive a grinding mechanism 5 to reciprocate in the Y-axis direction of the frame 1;

[0028] Specifically, the transverse moving mechanism 2 can be moved by means of an electric slide rail, including a worm gear transmission mechanism or a transmission roller mechanism, so that the frame 1 moves on the transverse guide rail, ensuring motion grinding while preventing the movement position of the transmission part from deviating.

[0029] The longitudinal moving mechanism 3 drives the frame 1 to move longitudinally through the travel motor and the gear transmission mechanism;

[0030] In conjunction with the instruction manual Figure 1-2 As we know, the grinding method of the grinder is as follows:

[0031] Grinding method 1: The grinding head 13 moves from the "zero point" to position C, the grinding head 13 floats down, and the grinding mechanism 5 is moved to position D, the grinding head 13 floats up; it quickly returns to the grinding point C, and then the grinding mechanism 5 moves a certain distance in the direction of B; when arriving at position B, the grinding head 13 and the grinding mechanism 5 return to zero.

[0032] Grinding method two, the grinding head 13 moves from the "zero point" to the C position, the grinding head 13 floats down, and the grinding mechanism 5 is moved to the D position, the grinding head 13 floats up; then the grinding head 13 floats down from the D position, and the grinding mechanism 5 is moved to the C position, the grinding head 13 floats up; then the grinding mechanism 5 moves a certain distance in the B direction, and then the grinding mechanism 5 moves a certain distance in the B direction; when arriving at the B position, the grinding head 13 and the grinding mechanism 5 return to zero.

[0033] Grinding method three, the grinding head 13 moves from the "zero point" to position C, the grinding head 13 floats down, grinds from position C to position D, and then grinds from position D to position C, reciprocating grinding, the grinding mechanism 5 moves from the "zero point" to position A and can grind position B at a uniform speed; when reaching position B, the grinding head 13 and the grinding mechanism 5 return to zero.

[0034] The grinding mechanism 5 includes a cover plate 6 symmetrically fixed on the frame 1, a lifting block 8 movably connected to the bottom end of the cover plate 6 through a guide column 7, a floating cylinder 9 connected to the cover plate 6 is installed on the lifting block 8, and positioning columns 11 fixed on the compression spring 10 are installed on both sides of the outer wall of the lifting block 8. The bottom of the compression spring 10 is installed on the frame 12. As the floating cylinder 9 is started, the compression spring 10 drives the grinding head 13 to contact the plate, and at the same time, the driver drives the grinding head 13 to grind the plate on the workbench.

[0035] Specifically, the lifting block 8 is provided with front and rear adjustment bolts 14 and height limit bolts 15 corresponding to the front and rear and up and down adjustment of the grinding head 13, and the frame 12 is provided with left and right adjustment bolts 16 for left and right adjustment of the grinding head 13.

[0036] The cooperation between the front and rear adjustment bolts 14, the height limit bolts 15 and the left and right adjustment bolts 16 can drive the grinding head 13 to adjust its position in space, thereby effectively preventing the grinding head 13 from running off track during operation, thereby improving the grinding quality and accuracy. In addition, the frame 12 is provided with a hook 19 connected to the compression spring 10, which can facilitate the disassembly of the structure while providing corresponding supporting force for the frame 12, so that the elastic action of the compression spring 10 can enable the grinding head 13 to adaptively press the plate.

[0037] The height limiting bolt 15 cooperates with the compression spring 10 to play a dual role in adjusting the height of the grinding head 13, thereby facilitating the height limiting of the grinding head 13 to adapt to the grinding plates of different thicknesses.
