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.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a horizontal sanding machine transmission system, including a frame 1, a pulley protection cover 2 is provided on one side of the frame 1, the pulley protection cover 2 is connected to the frame 1 by bolts, a cold air inlet 3 is opened on the top of the side of the pulley protection cover 2 close to the frame 1, a driving motor 4 is provided inside the cold air inlet 3, the driving motor 4 is fixedly installed on the frame 1, a motor protection cover 5 corresponding to the driving motor 4 is provided on the outside of the driving motor 4, and the motor protection cover 5 is connected to the pulley protection cover 2, such as Figure 2 As shown, air with low external temperature will enter the motor protection cover 5 and the pulley protection cover 2 through the cold air inlet 3, and will drive the heat generated by the drive motor 4 along the way, thus avoiding the accumulation of heat on the drive motor 4 and causing continuous temperature rise.

[0023] A first transmission shaft 9 is provided below the driving motor 4, one end of the first transmission shaft 9 is rotatably connected to the frame 1, and a pulley 10 is coaxially mounted on the other end of the first transmission shaft 9 and the output end of the driving motor 4, and the pulleys 10 are connected by belts. Figure 2 As shown, the driving motor 4 can drive the first transmission shaft 9 to rotate through the pulley 10 and the belt, thereby driving the grinding component to operate.

[0024] It should be noted that if Figure 1 , Figure 2 As shown, the grinding cylinder 19 component is arranged on the side away from the pulley protection cover 2, and its internal crushing shaft is connected to the first transmission shaft 9. In the utility model, the driving motor 4 will drive the crushing shaft to rotate through the pulley 10 and the belt to crush the material.

[0025] A hot air outlet 15 is provided at the bottom of the other side of the pulley protection cover 2, and a mounting shell 13 is provided on one side of the hot air outlet 15. The mounting shell 13 is connected to the pulley protection cover 2, and a second transmission shaft 17 is coaxially connected inside the mounting shell 13. A blowing fan is installed on the outer side of the second transmission shaft 17. Flanges 16 are installed on the ends of the first transmission shaft 9 and the second transmission shaft 17 that are close to each other, and the flanges 16 are connected by bolts, such as Figure 2 As shown, by setting the flange 16, the first transmission shaft 9 will drive the second transmission shaft 17 and the blowing fan to rotate together when rotating, thereby guiding the air that has absorbed the heat to be quickly discharged from the mounting shell 13, and the heat is repeatedly taken away from the drive motor 4 in this cycle, so that it always runs at a stable temperature.

[0026] like Figure 2 As shown, the blowing fan includes a fixing ring 6, which is coaxially connected to the second transmission shaft 17 through a key and the second transmission shaft is provided with a nut for positioning the fixing ring, a plurality of rotating blades 18 are vertically provided on the outer side of the fixing ring 6, and the plurality of rotating blades 18 are equidistantly distributed circumferentially along the outer surface of the second transmission shaft 17, and the bottom ends of the rotating blades 18 are connected to the fixing ring 6. The rotating blades 18 with a flat spindle-shaped structure have strong wind force, which can promote the rapid discharge of heat from the mounting shell 13.

[0027] like Figure 2 As shown, a first arc-shaped air guide structure 12 is provided at the top of the inner wall side of the pulley protection cover 2 away from the motor protection cover 5, and a second arc-shaped air guide structure 14 is provided at the bottom of the inner wall side of the pulley protection cover 2 away from the mounting shell 13. By arranging the first arc-shaped air guide structure 12 and the second arc-shaped air guide structure 14, the air flow rate is increased, and the air with heat can be quickly blown to the hot air outlet 15 and discharged.

[0028] like Figure 1 As shown, a dust filter 7 is provided at the end of the motor protective cover 5 away from the pulley protective cover 2. The outer side of the dust filter 7 is connected to one side of the motor protective cover 5 by a lock or a bolt. By setting the dust filter 7, impurities such as dust in the air can be intercepted to prevent impurities from entering the interior of the pulley protective cover 2, thereby improving applicability.

[0029] Furthermore, a heat dissipation port 11 is provided at one end of the mounting shell 13 away from the pulley protection cover 2. The mounting shell 13 is connected to the outside through the heat dissipation port 11. A protective net is installed in the heat dissipation port. The heat dissipation port 11 is provided to facilitate air circulation.

[0030] like Figure 2As shown, a shaft sleeve 8 is coaxially provided on the outer side of the first transmission shaft 9. The shaft sleeve 8 is rotatably connected to the first transmission shaft 9 through a bearing. One end of the shaft sleeve 8 is connected to the frame 1. By providing the shaft sleeve 8, the overall strength of the first transmission shaft 9 is improved, and the first transmission shaft 9 and the second transmission shaft 17 can rotate more stably and smoothly, and the heat dissipation effect is better.

[0031] To sum up, when the horizontal sander transmission system is in use, the driving motor 4 drives the first transmission shaft 9 and the sanding cylinder 19 to rotate through the pulley 10 and the belt, and the first transmission shaft 9 then drives the rotating fan blade 18 assembly to rotate together, so that the external air enters the pulley protection cover 2 and the motor protection cover 5 through the cold air inlet 3 and takes away the working heat of the driving motor 4 along the way and discharges it, and this cycle is repeated to avoid heat accumulation and cause short circuit damage to the driving motor 4.

[0032] Finally, when the rotating fan blades 18 rotate, they will drive the external cold air into the motor protective cover 5 through the dust filter. Since the axis of the motor protective cover is parallel to the heat sink on the surface of the drive motor, the air flowing through the motor protective cover 5 can take away the heat on the surface of the drive motor, thereby reducing the surrounding heat of the drive motor. The heat will pass through the pulley protective cover and finally be discharged to the outside from the mounting shell, allowing the heat outside the drive motor to be quickly dissipated.
