DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.

[0020] The utility model provides Figure 1 to Figure 4The sanding head structure of a wide-band sanding machine shown in the figure comprises a machine base 1, a Y-shaped frame is arranged above the machine base 1, and the Y-shaped frame comprises two first support plates 2 and a second support plate 3. A sliding channel 4 is provided on the second support plate 3, and a slide plate 5 is slidably connected inside the sliding channel 4. In order to improve the sliding stability of the slide plate 5, a slide groove 6 is provided on the inner wall of the sliding channel 4, and a slider 7 is slidably connected inside the slide groove 6, and the slider 7 is fixedly connected to the slide plate 5. A first roller 8 is rotatably connected to the slide plate 5, and an electric push rod 9 is fixedly connected to the inner wall of the sliding channel 4. The slide plate 5 is fixedly connected to the telescopic end of the electric push rod 9. The electric push rod 9 can drive the slide plate 5 to slide inside the sliding channel 4, and the position of the first roller 8 is adjusted by the slide plate 5. A second roller 10 is rotatably connected to the end of the first support plate 2, and the first roller 8 and the two second rollers 10 are connected by a sand belt 11 for transmission. The sand belt 11 is a wide-band structure, and the workpiece is sanded by the sand belt 11.

[0021] The Y-shaped frame is provided with a driving assembly for driving the sanding belt 11 to rotate, and the driving assembly includes a first motor 12, the first motor 12 is fixedly connected to the Y-shaped frame, and one of the second rollers 10 is fixedly connected to the driving shaft of the first motor 12. Specifically, the first motor 12 drives the second roller 10 fixedly connected to its driving shaft to rotate, and under the cooperation of the other second roller 10 and the first roller 8, the sanding belt 11 rotates, thereby sanding the workpiece.

[0022] When the planar position of the plate needs to be processed, the abrasive belt 11 is adjusted to Figure 4 In this state, the plate is placed under the two second rollers 10 and fits on the outer ring of the abrasive belt 11, and the abrasive belt 11 rotates to sand the workpiece; in addition, the position between the second roller 10 and the first roller 8 can also be sanded.

[0023] When it is necessary to process the protruding part of the plate, the protruding part of the plate is abutted against the outer ring of the abrasive belt 11 between the two second rollers 10, and the telescopic end of the electric push rod 9 is controlled to be retracted, so that the first roller 8 moves toward the workpiece, and the abrasive belt 11 becomes loose to a certain extent. In this process, the plate is squeezed toward the first roller 8, so that the abrasive belt 11 is covered on the protruding part of the plate. At the same time, the abrasive belt 11 is still in a tensioned state, and the abrasive belt 11 rotates, thereby sanding the protruding part of the workpiece. In specific use, a positioning device can be set to clamp and position the workpiece, and cooperate with the squeezing of the workpiece to make the protrusion better abut against the outer ring of the abrasive belt 11.

[0024] When it is necessary to process the concave position of the plate, the concave part of the plate is abutted against the outer ring of the abrasive belt 11 at the first rotating roller 8. Since the abrasive belt 11 is in an arc-shaped structure here, the concave part of the plate can be sanded; at the same time, the abrasive belt 11 is in a tensioned state, and the abrasive belt 11 rotates, thereby sanding the concave part of the workpiece. In addition, it can also be on the outer ring of the abrasive belt 11 at the second rotating roller 10.

[0025] The utility model can meet the sanding processing requirements of plates of various shapes and improve the applicability of the wide-band sanding machine by arranging structures such as the first supporting plate 2, the second supporting plate 3, the electric push rod 9 and the sanding belt 11.

[0026] In order to realize the rotation of the Y-shaped frame, a vertical plate 16 is fixedly connected to the top of the machine base 1, a rotating shaft 14 is passed through the top of the vertical plate 16, the rotating shaft 14 is rotatably connected to the vertical plate 16, the Y-shaped frame is fixedly connected to the rotating shaft 14, a second motor 15 is fixedly connected to the vertical plate 16, and the rotating shaft 14 is fixedly connected to the driving shaft of the second motor 15. Specifically, the rotation of the second motor 15 drives the rotating shaft 14 to rotate, thereby driving the Y-shaped frame to rotate.

[0027] In order to improve the stability of the Y-shaped frame during the sanding process, a positioning component is arranged between the Y-shaped frame and the vertical plate 16, and the positioning component includes an elastic telescopic rod 13, an electromagnet 17 and a ring 18. The elastic telescopic rod 13 is fixedly connected to the vertical plate 16, and the ring 18 is fixedly connected to the end of the elastic telescopic rod 13 away from the vertical plate 16. The electromagnet 17 is fixedly connected to the Y-shaped frame, and the electromagnet 17 and the ring 18 cooperate. The ring 18 is made of a material affected by magnetic force, such as iron material.

[0028] During operation, the second motor 15 rotates to drive the rotating shaft 14 to rotate, and then drives the Y-shaped frame to rotate, so as to adjust the grinding direction of the sanding belt 11. After the adjustment is completed, the electromagnet 17 is started. Under the magnetic force of the electromagnet 17, the ring 18 moves toward the Y-shaped frame and is adsorbed on the electromagnet 17 to prevent the Y-shaped frame from shaking.

[0029] When the direction of the Y-shaped frame needs to be adjusted, the electromagnet 17 is turned off, and the ring 18 is reset under the reset elastic force of the elastic telescopic rod 13. There is a certain gap between the ring 18 and the electromagnet 17 to avoid friction with the electromagnet 17.
