[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] Example

[0025] Reference Figure 1-4 The utility model provides an embodiment: a multifunctional sanding belt machine, including a bottom steel plate 2, a sanding belt and a power cord 3. A vertical support aluminum material 11 is fixedly arranged at the rear side of the upper end surface of the bottom steel plate 2. Aluminum has the advantages of corrosion resistance, lightness, high hardness and high thermal conductivity. The support of the aluminum material makes the sanding belt machine stronger and more durable. A horizontal support aluminum material 10 is fixedly arranged at the middle position of the front end surface of the vertical support aluminum material 11, and a motor 4 is fixedly arranged at the middle position of the rear end surface of the vertical support aluminum material 11. The motor 4 is the power source of the entire machine and provides power for the sanding belt machine. The motor 4 drives the roller at its output end to rotate, thereby driving the sanding belt body 6 to rotate. The sanding belt body 6 is driven by the motor 4. The roller at the outlet, the roller on the tensioning wheel mechanism 5 and the roller on the driven wheel mechanism 8 are tightened and supported, and the objects can be polished through the sanding belt body 6. The tensioning wheel mechanism 5 is fixedly arranged at the upper side of the front end surface of the vertical support aluminum material 11. By pinching and pulling the grip on the tensioning wheel mechanism 5, the tensioning wheel mechanism 5 can be bent to pull the sanding belt body 6, so as to facilitate the control of the tightness of the sanding belt body 6, thereby facilitating the installation and disassembly of the sanding belt body 6. In addition, when the sanding belt body 6 works for a long time, it will become loose due to work fatigue. At this time, it is necessary to bend the tensioning wheel mechanism 5 to tighten the tensioning wheel mechanism 5 to make the sanding belt body 6 straight, so that the sanding belt body 6 is always in a suitable grinding state;

[0026] The motor 4 can be used to drive the sanding belt machine to rotate, and the tightness of the sanding belt body 6 can be controlled by turning the tensioning wheel mechanism 5, so that the sanding belt machine can be used conveniently.

[0027] An adjusting mechanism 7 is fixedly provided at the middle position on one end face of the transverse supporting aluminum material 10. By turning the adjusting joint, the adjusting mechanism 7 can loosen the fixation of the transverse supporting aluminum material 10, and the adjusting mechanism 7 and the aluminum material above it are slid forward to a suitable position, and the adjusting mechanism 7 is turned again to fix the transverse supporting aluminum material 10 again, so as to adjust the extension length of the grinding platform 9, which is convenient for placing objects of different lengths and sizes. The objects are placed on the grinding platform 9 and gradually approach the abrasive belt body 6, and the end faces of the objects are grinded and polished by the abrasive belt body 6. A grinding platform 9 is fixedly provided at the front position on the upper end face of the adjusting mechanism 7. The grinding platform 9 is a plane. The objects are placed on the grinding platform 9, and then the angle of the objects is adjusted to slowly approach the abrasive belt body 6. The abrasive belt body 6 driven by the motor 4 to rotate will grind and polish the slowly approaching objects. The objects to be polished are more convenient to use. A driven wheel mechanism 8 is fixedly arranged at the front position of the other end face of the horizontal supporting aluminum material 10. The driven wheel mechanism 8 will pull the sanding belt body 6 toward the grinding platform 9 into a long plane, and the objects gradually approaching on the grinding platform 9 can be polished through the pulled plane. The driven wheel mechanism 8 is used to assist the sanding belt body 6 in driving and rolling. The driven wheel mechanism 8 has an upper roller and a lower roller, which can pull the sanding belt body 6 apart for easy grinding. A switch 1 is fixedly arranged at one side position on the front side of the upper end face of the bottom steel plate 2. The switch 1 is connected to the power cord 3, and the switch 1 is connected to the motor 4. The motor 4 can be controlled by pressing the switch 1. The motor 4 can be controlled at any time to select whether the rolling of the sanding belt body 6 needs to be carried out, and the switch 1 makes the sanding belt machine more convenient to use.

[0028] When the belt sander is in use, the power cord 3 is used to connect to an external power source, the switch 1 is used to start the motor 4 to drive the belt to rotate, the object is placed on the grinding platform 9 and gradually moved closer to the belt for grinding, and the position of the grinding platform 9 can be adjusted by turning the adjustment mechanism 7, so as to facilitate the adjustment of the grinding distance of the object.

[0029] The sanding belt body 6 is arranged between the output end of the motor 4, the tensioning wheel mechanism 5 and the end face of the driven wheel mechanism 8. The sanding belt body 6 is supported by the wheel disc at the protruding end of the motor 4, the roller above the tensioning wheel mechanism 5, and the rollers above and below the driven wheel mechanism 8. The tightened sanding belt body 6 can grind the objects placed on the grinding platform 9. The power cord 3 is connected to the switch 1, and the switch 1 is electrically connected to the motor 4. When the sanding belt machine is manufactured, the switch 1 and the motor 4 are first connected with an electric wire, and then the power cord 3 is connected to the switch 1, and the power cord 3 is inserted into the socket to transmit the power to the card block, which is converted by the switch 1 to the motor 4 to transmit power to the motor 4. The motor 4 is started by the power, and the started motor 4 drives the wheel disc at its output end to rotate, and the rotating wheel disc drives the sanding belt body 6 to rotate, so that the objects on the grinding platform 9 are grinded by the rotating sanding belt body 6;

[0030] The sanding belt of the machine is supported by a motor 4, a tensioning wheel mechanism 5 and a driven wheel mechanism 8, so that the sanding belt can grind objects. The switch 1 is connected through a power cord 3 to provide power to the machine. The motor 4 can be controlled by the switch 1. The switch 1 is connected to the live wire of the power supply. When the switch 1 is turned off, the live wire will disconnect the transmission of power. When the switch 1 is turned on, the live wire will be connected to continue to transmit power again, thereby achieving the function of controlling the motor 4, which is convenient for controlling the rotation of the sanding belt wheel.

[0031] Working principle: The sanding belt machine consists of a switch 1, a bottom steel plate 2, a power cord 3, a motor 4, a tensioning wheel mechanism 5, a sanding belt body 6, an adjustment mechanism 7, a driven wheel mechanism 8, a grinding platform 9, a horizontal support aluminum material 10 and a vertical support aluminum material 11. When the sanding belt is used, it is connected to the power supply through the power cord 3, and the motor 4 is started through the switch 1 to drive the sanding belt body 6 to rotate. The object is placed on the grinding platform 9, and the object is brought close to the sanding belt body 6 for grinding, making the sanding belt machine more convenient to use.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
