Detailed Description

The following are only preferred embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention.

In the present embodiment, the words such as "left", "right", "inner", "outer", etc. describing the directional relationship are only for convenience of description of the embodiment, and are not to be considered as limitations of the present invention. The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The fixed connection means includes, but is not limited to, welding, screwing, pipe clamps or water pipe joints, etc. known in the art.

Fig. 1 to 6 show an embodiment of the present invention. This embodiment provides a pencil plate straightening device. The pencil board straightening device comprises a circular bottom plate 1, wherein a cylindrical stand column 3 is welded at the circle center of the upper surface of the circular bottom plate 1. The upper surface of the bottom plate 1 is provided with a plurality of rectangular straightening frames 2, and the straightening frames 2 are welded on the bottom plate around the upright posts 3 in a radial shape. One end of each straightening frame 2 facing the upright post 3 is a movable extrusion plate 9, and other three surfaces are metal plates welded on the bottom plate 1. The pressing plate 9 can slide freely in the straightening frame 2 in the radial direction of the bottom plate 1. Two parallel first connecting lug stands 7 are welded on each extrusion plate 9, and through holes are arranged on the first connecting lugs 7. The upper end of the upright post 3 is provided with an external thread 301, the surface of the lower end of the upright post is provided with a smooth end, and the smooth end is provided with a blind hole 302. The lower end of the upright post 3 is sleeved with a sliding sleeve 10, the outer side wall surface of the sliding sleeve 10 is welded with a plurality of second connecting lugs 8 matched with the first connecting lugs, and through holes are also formed in the second connecting lugs 8. The outer side wall of the sliding sleeve 10 is also provided with a plug hole 101 matching the blind hole 302. The insertion of the plug 11 into the blind hole through the plug hole 101 serves to restrict the position of the sliding sleeve 10. A connecting rod 5 is connected between the sliding sleeve 10 and the compression plate 9, i.e. the connecting rod 5 is hinged to the first and second connecting lugs 8 via hinge rods 501 at both ends.

The hand wheel 4 is sleeved at one end, provided with the external thread 301, of the upright post 3, the hand wheel 4 comprises an extrusion sleeve 403 provided with a first through hole 403, an internal thread 401 matched with the external thread 301 is arranged on the inner wall of the extrusion sleeve 403, a plurality of handles 6 are welded on the outer wall of the extrusion sleeve 403, and the handles 6 are distributed radially.

The length and width of the straightening frame 2 should be integral multiples of the length or width of the pencil board respectively to ensure that the straightening frame 2 can fully play a role.

Before use, the bolt 11 is inserted into the blind hole 302 through the bolt hole 101, the pressing plate 9 is just at the opening of the straightening frame 2 towards one end of the upright post 3, a worker puts a pencil plate into the straightening frame 2 and then takes off the bolt 11, and the sliding sleeve 10 does not slide downwards due to the limitation of the pencil plate in the straightening frame 2. At this moment, the hand wheel 4 is rotated, the extrusion sleeve 403 of the hand wheel 4 pushes the sliding sleeve 10 to move downwards along the upright post 3, the sliding sleeve 10 pushes the extrusion plate 9 through the connecting rod 5 to extrude the pencil plate along the radial direction of the bottom plate 1, and the hand wheel stops rotating after the extrusion plate 9 is compressed.

After straightening, a worker rotates the hand wheel 4 in the opposite direction, manually lifts the sliding sleeve 10, inserts the bolt 11 back into the pin producing hole 101 and the blind hole 302, and then takes out the pencil board for later use.
