Detailed Description

In the structure shown in fig. 2, both left and right ends of the redirecting roller 3 are respectively mounted on the support shaft 4 through one bearing 2, the bearing 2 is mounted in the bearing block 1, and the bearing block 1 is fixedly connected with the support shaft 4. The support shaft 4 corresponds to the support of the redirecting roller 3, and in the embodiment of the invention, the support of the redirecting roller 3 is position-changeable, and the changeable direction is vertical.

In fig. 2, the left and right ends of the fulcrum 4 are each provided with one locked portion, and the two locked portions are guided in the vertical direction, so that the fulcrum 4 has only the vertical degree of freedom due to the guiding, and the remaining degrees of freedom are restrained. Further, a constraint structure of vertical degrees of freedom is arranged, so that all degrees of freedom of the support shaft 4 can be limited, and locking is formed.

The constraint of the fulcrum 4 on the vertical freedom is adjustable, and the adjustment of the vertical position of the fulcrum can be realized.

In fig. 3, two members for restricting the vertical degree of freedom of the fulcrum 4, one for the position adjustment of the locked portion and the other for the locking after the adjustment of the locked portion.

Specifically, regarding the supporting shaft locking mechanism shown in fig. 1 to 3, for locking the supporting shaft 4 of the paper output redirecting roller 3 of the corrugated paper sizing machine, the basic structure is configured as follows:

with respect to the locked portion, it comprises two basic portions, one of which is a first portion for connection with the fulcrum 4 and the other of which is a second portion adjusted to be locked. The two parts can be of an integral structure or can be assembled in a split way.

Wherein the first part is intended for the connection of the locked portion to the shaft end of the fulcrum 4, which can be understood as the seat of the fulcrum 4.

The second part provides a wedge 10, in the view direction shown in fig. 3, the wedge 10 presents a right-angle trapezoidal block, two right-angle sides of which are horizontal, the corresponding surfaces form the lower surface of the wedge 10, denoted as horizontal surface, and the other right-angle side corresponds to the vertical surface shown in the figure, which is the assembly surface of the wedge 10 with the connecting seat 8 shown in fig. 3.

Wherein the horizontal plane is one waist corresponding to the right trapezoid block, the other waist is necessarily an inclined plane, and the outsoles of the two bottoms of the right trapezoid block are left in the figure, thereby determining the inclination direction of the inclined plane, which is expressed as being inclined to the shaft end (the shaft end is the shaft end of the aforementioned fulcrum 4) and to the axis (the axis is necessarily the axis of the fulcrum 4).

With respect to the horizontal plane, it is understood that the supported surface of the wedge 10, while the inclined surface is understood that the locked surface of the wedge 10.

The guide portion may be configured as a guide rail structure or a guide groove structure, for example, a guide rail structure, which is used to restrict other degrees of freedom of the locked portion, and may be mounted on the wall plate 14 of the corrugating machine.

Since the adjustment travel is relatively small, in a preferred embodiment the guide is configured as a guide slot structure.

In the construction shown in fig. 3, a bolt housing 11 is provided, and in some embodiments, the bolt housing 11 is a rectangular block having one side welded or bolted to the wall panel 14, and in some embodiments, a number of reinforcing plates are welded between the lower bottom surface of the rectangular block and the wall panel 14.

The reinforcing plate may be added between the upper surface of the rectangular block and the wall plate 14.

The bolt seat 11 is provided with a vertically threaded hole, the axis of which faces the lower surface, so that the adjusting bolt 13 arranged in the threaded hole can support the horizontal plane, namely the lower surface of the wedge 10, and form restraint and position adjustment on the lower side of the vertical freedom of the wedge 10.

The number of the threaded holes is one or two, so that too many threaded holes are not suitable, otherwise, the equivalent supporting surface of the adjusting bolt 13 corresponding to the plurality of threaded holes is difficult to adjust.

As for the adjusting bolt 13, as shown in fig. 3, the bolt head of the adjusting bolt 13 is downward, and the adjusting bolt 13 can be adjusted using, for example, a spanner. The adjusting bolt 13 is engaged with the screw hole, and the upper end thereof is pressed against the lower surface, thereby forming a support for the wedge 10 in the vertical direction.

With regard to the locking of the wedge 10 after the support of the adjusting screw 13, a locking assembly is provided, which is firstly the construction of the frame part, which requires a reliable mounting base, in fig. 3 a cylinder block 6 or the like is provided, which is a seat fixedly mounted on the wall plate 14 shown in fig. 3, which seat is fixedly mounted by means of screws.

The wall plate 14 and the seat are provided with through holes for the passage of the locking members, said through holes being axial holes for indicating the axial ends directed towards the fulcrum 4. The seat is denoted as a locking seat.

The bevel engagement has the feature that the force of the locking means acting on the bevel of the wedge 10 has a vertical component in a direction opposite to the direction of the supporting force of the adjusting bolt 13 acting on the wedge 10, so that the wedge 10 can be reliably restrained.

The inclined surface can be adapted to a certain amount of vertical travel, so that the adjustment of the adjusting bolt 13 is satisfied.

The thread of the adjusting bolt 13 adopts self-locking threads, so that looseness generated by vibration of the machine can be effectively reduced. In the preferred embodiment, the adjusting bolt 13 is provided with a lock nut 12, and the lock nut 12 can provide a certain pretightening force, so that loosening caused by machine vibration is effectively relieved, and the reliability of supporting the wedge 10 is improved.

In a preferred embodiment, the locking member is a lever member that is easily guided and the direction of the force is easily controlled.

The axis of the lever is parallel to the axis of the fulcrum 4.

The engagement of the lever with the inclined surface may be a point contact, a line contact or a surface contact, and preferably a surface contact, and even if the point contact or the line contact is adopted, the force is relatively large, and the lever is deformed by the force, so that the surface contact is substantially formed.

In a preferred embodiment, the end of the shank has a working surface that engages the bevel, in other words, the working surface of the shank is also bevel, the bevel that forms the working surface being parallel to the bevel on the wedge 10 when the shank is disengaged from the wedge 10, and the two bevels engaging when the shank is engaged with the wedge 10, noted as being coplanar. The inclined plane constituting the working surface is denoted as active inclined plane.

Since the movement pattern of the rod-like member is linear movement, which is one of the most conventional movement patterns in the mechanical field, a linear movement mechanism, particularly a linear movement mechanism having a buffering capacity, can be applied to the present embodiment, for example, a cylinder assembly such as a thin-walled cylinder 15 shown in fig. 3, the push rod 7 of which constitutes the locking member.

As for the locked portion, as shown in fig. 2 and 3, it is an assembly structure which can relatively improve maintainability as compared with an integral structure.

Specifically, as shown in fig. 3, the locked portion includes a connecting seat 8, one (left side shown in fig. 3) of opposite sides (left and right sides shown in fig. 3) of the connecting seat 8 is for fixedly connecting with the shaft end of the fulcrum 4, and the other (right side shown in fig. 3) is detachably connected with the wedge 10.

The wedge blocks 10 are detachably connected, so that maintainability can be improved, and the wedge blocks 10 with different slope angles can be selected according to different working conditions, so that better adaptability is achieved.
