[0054] Example 2

[0055] like Figure 1 As shown, the utility model provides a back pressure plate gap adjustment device for a screw stacking machine, comprising: a back pressure plate 1, a screw stacking spindle 2 and a snap sleeve 3. An opening is opened through the back pressure plate 1, and the screw stacking spindle 2 is inserted into the opening to realize the assembly of the back pressure plate 1 and the screw stacking spindle 2. A snap sleeve 3 is also provided at the connection between the screw stacking spindle 2 and the back pressure plate 1, so that the connection and fixation of the back pressure plate 1 and the screw stacking spindle 2 are realized by the snap sleeve 3.

[0056] In this embodiment, the inner diameters of the snap-on sleeve 3 at the points where it fits with the outer wall of the screw stacking spindle 2 and the outer wall of the back pressure plate 1 are different. By setting different inner diameters to clamp the position of the matching back pressure plate 1 or the screw stacking spindle 2, the back pressure plate 1 is fixed.

[0057] In the above scheme, the provision of the snap-in sleeve 3 makes the connection and fixation between the back pressure plate 1 and the screw stacking spindle 2 more convenient, simplifies the operation process, and greatly improves work efficiency; since the inner diameters of the snap-in sleeve 3 at the connection between the screw stacking spindle 2 and the back pressure plate 1 are different, it can accurately lock the positions of the two, ensuring that the back pressure plate 1 cannot move forward and backward, thereby ensuring the stability of the screw stacking machine operation.

Each circle contains 4 first slots. During installation, the position of the first slot that cooperates with the snap sleeve 3 can be selected as needed to adjust the gap of the back pressure plate 1.

[0060] In the above scheme, multiple groups of first slots are axially opened on the screw stacking spindle 2, so that the gap of the back pressure plate 1 can be adjusted, and the setting of multiple groups of first slots also improves the accuracy of the gap adjustment of the back pressure plate 1. The precise control of the gap of the back pressure plate 1 is conducive to the normal operation of the screw stacking machine.

[0061] like Figure 2 As shown, in the preferred embodiment, the back pressure plate 1 includes: a connecting plate 12 and a back pressure plate sleeve 11. The back pressure plate sleeve 11 is cylindrical as a whole, one end of the back pressure plate sleeve 11 is connected to the connecting plate 12, and the axial direction of the back pressure plate sleeve 11 is perpendicular to the connecting plate 12. An opening for the screw-stacked spindle 2 to pass through is provided on both the back pressure plate sleeve 11 and the connecting plate 12. In addition, a plurality of second card slots are provided on the back pressure plate sleeve 11, and the connection with the snap sleeve 3 is achieved through the second card slots. The connection method between the second card slots and the snap sleeve 3 makes the installation of the snap sleeve 3 and the back pressure plate 1 more convenient.

[0062] In this embodiment, the snap sleeve 3 is sleeved on the outside of the back pressure plate sleeve 11, and the end of the snap sleeve 3 close to the back pressure plate 1 abuts against the connecting plate 12 to realize the connection between the snap sleeve 3 and the second slot on the back pressure plate sleeve 11.

[0064] In the above scheme, the setting of the first inner wall ensures that the snap sleeve 3 can be tightly mounted on the screw-stack main shaft 2, and the end of the first inner wall abuts against the end of the back pressure plate sleeve 11, limiting the movement of the back pressure plate 1 in the axial direction; at the same time, the second inner wall cooperates with the second slot on the back pressure plate sleeve 11, further fixing the position of the back pressure plate 1 so that it cannot move forward and backward.

It can be imagined that the shape of the first slot on the screw-stack spindle 2 that cooperates with the elastic protrusion and the shape of the second slot on the back pressure plate sleeve 11 that cooperates with the elastic protrusion should match the shape of the elastic protrusion. When installing the snap-on sleeve 3, the snap-on sleeve 3 can be directly installed after determining the desired installation position. When the elastic protrusion is aligned with the first slot or the second slot, the elastic protrusion pops out under the action of the spring 35 to achieve position fixation.

The installation process is simple and the installation efficiency is improved. At the same time, the setting of the spring 35 also reduces the impact of vibration during the operation of the equipment and does not affect the use of the snap-on sleeve 3.
