Description

A rotary disk screw drive device of a particle friction tub washing machine

technical field

The utility model relates to a rotary disk screw driving device of a particle friction tub washer, which belongs to the parts of the particle friction tub washer.

Background technique

The previously applied 201821345525.9 is a driving device for the rotating disk of a pellet washing machine. The speed of the cylinder driving the rotating disk is obviously affected by the working air pressure and causes instability. This instability will cause the instability of the entire system, thereby causing Equipment failure.

SUMMARY OF THE INVENTION

In order to solve the above problems, the concept of "Cam Divider" is introduced into the particle friction tub washing machine to solve the driving of the rotating disc;

The invention provides a rotary disk screw drive device of a particle friction tub washing machine, which includes a rotary disk, a boss of the rotary disk, a screw driver, a deceleration motor, and a transmission shaft; it is characterized in that: the boss of the rotary disk falls down In the guide groove of the screw driver, the geared motor drives the screw driver to rotate through the transmission shaft, thereby pushing the rotating disk to do intermittent motion. This driving method is accurate, reliable and relatively simple, effectively solves the problem of driving the rotating large disk, and improves the reliability of equipment operation.

Detailed ways

As can be seen from Figure 1, the relative positions of the rotary disc (1) and the geared motor (2) in the tub washing machine; as can be seen from Figure 2, the rotary disc screw drive device after removing irrelevant parts in Figure 1 ; The reducer (2) transmits the power to the screw drive (4) through the transmission shaft (3), and the bearing (5) is supported as one end of the transmission shaft (3); the boss (1.1) is arranged on the rotating disc (1); It can be seen from Figures 4 and 5 that the boss (1.1) of the rotary disk (1) is stuck in the driver guide groove (4.1) of the screw driver (4); when the screw driver (4) presses the screw driver turning arrow ( 4.2) When rotating in the direction, the guide groove (4.1) of the driver pushes the boss (1.1) and the rotary disk to move in the direction indicated by the arrow (1.3) of the direction of motion of the rotary disk (see Figure 5).

Fig. 3 is a schematic axonometric view of the screw driver, the driver guide groove (4.1) scans along the path of the track line (4.3) and is wound on the screw driver (4). (See Figure 6 for the trace line (4.3))

Fig. 6 is the track line (4.3) of the guide groove (4.1) of the screw driver; the track line (4.3) is formed by connecting the spiral line (4.31) and the plane arc line (4.32); the plane of the plane arc line (4.32) is connected with the The axis of rotation of the screw drive (4.4) is vertical.

The screw driver (4) pushes the boss (1.1) into the area of the plane arc line (4.32) in Figure 6. Since this area is in a rotating plane, the rotating disc (1) stops intermittently (see Figure 4).

The trajectory line (4.3) of the guide groove of the screw driver in Fig. 6 is formed by connecting 3 sections of spiral lines (4.31) and 2 sections of plane arc lines (4.32).

The guide groove trajectory line (4.3) of the screw driver can also be formed by connecting two sections of the spiral line (4.31) and one section of the plane circular arc line (4.32); 4.31) among them.
