Description

Technical Field

[0001] The invention relates to the technical field of die-cutting machine components, in particular to a sheet edge flipping mechanism. Background Art

[0002] The die-cutting machine needs lateral positioning during the conveying process of sheets. Lateral positioning is a process of pushing (or pulling) the sheet in a direction perpendicular to the running direction of the sheet for a distance until it hits the positioning block. The paper feeding platform where the sheet is located is composed of multiple belts as conveyor belts. Stainless steel plates are installed between the belts. There is a gap between the belts and the stainless steel plates in the positioning direction, and the belts are higher than the stainless steel plates. When the size edge of the sheet product made by the die-cutting machine is just at the edge of the paper feeding belt, once the sheet is bent and uneven, the lateral positioning process will hit the side of the belt, resulting in failure of lateral positioning.

[0003] Therefore, it is urgent to design a mechanism that can make the sheet jump over the belt to solve the problem that the edge of the sheet does not hit the belt during lateral positioning. Summary of the invention

[0004] The purpose of the present invention is to provide a sheet edge flipping mechanism in order to overcome the defects of the above-mentioned prior art. By raising the stainless steel plate between the belts so that the edge of the stainless steel plate covers the edge of the belt, the sheet can flip over the belt, effectively solving the problem of the edge of the laterally positioned sheet not hitting the belt.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The present invention provides a sheet edge flipping mechanism, comprising a bottom plate, a stainless steel plate, a belt, a side positioning mechanism and a paper feeding platform;

[0007] The stainless steel plate is connected to the bottom plate via a fixing member; a boss is provided on the stainless steel plate;

[0008] The belt is placed on the bottom plate; the side positioning mechanism and the paper feeding platform are fixed to the external wall panels respectively;

[0009] The bottom plate is provided with two installation areas. When the stainless steel plate is located in the first installation area, the stainless steel plate contacts the bottom plate; when the stainless steel plate is located in the second installation area, the boss contacts the bottom plate.

[0010] Furthermore, the stainless steel plate is provided with a plurality of fixing holes, and each of the fixing holes is provided with the boss.

[0011] Furthermore, the bottom plate is provided with a plurality of mounting holes for mounting the stainless steel plate.

[0012] Further, the mounting hole includes a first hole area, and the hole diameter of the first mounting hole is larger than the diameter of the boss.

[0013] Furthermore, a second hole area is provided on the mounting hole, the second mounting hole is in a communicating structure with the first mounting hole, and the hole diameter of the second mounting hole is smaller than the diameter of the boss.

[0014] Furthermore, the fixing members are nut plates and screws.

[0015] Furthermore, the nut plate is in an elongated strip shape, and a plurality of nut holes are provided on the nut plate.

[0016] Furthermore, the belt is fixed on an external rotating shaft.

[0017] Furthermore, the side positioning mechanism and the paper feeding platform are respectively screwed to the external wall panel, and the side positioning mechanism is used for side positioning of the sheet object.

[0018] Furthermore, the stainless steel plate is inserted between two adjacent belts.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] The present invention raises the stainless steel plates between the belts and moves the stainless steel plates laterally so that the edges of the stainless steel plates cover the edges of the belts. The stainless steel plates serve as guide surfaces, which can enable the sheet objects to jump over the belts with the edges of the paper above the belts, thereby effectively solving the problem that the edges of the sheet objects do not hit the belts during lateral positioning.

[0030] The specific implementation methods of the present invention are described in detail below through examples. These examples are implemented on the premise of the scheme described in the present invention, and provide detailed implementation methods and specific operating processes, but the protection scope of the present invention is not limited to the following examples.

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Component models, material names, connection structures and other features not clearly described in this technical solution are all considered to be common technical features disclosed in the prior art.

[0032] Example 1

[0033] The present embodiment provides a sheet edge flipping mechanism, comprising a base plate 1, a stainless steel plate 2, a belt 3, a side positioning mechanism 7 and a paper feeding platform 8; the stainless steel plate 2 is connected to the base plate 1 through a nut plate 4 and a screw 5, the nut plate 4 is a long strip and is provided with a plurality of nut holes; a boss 11 is provided on the stainless steel plate 2, and the stainless steel plate 2 is inserted between two adjacent belts 3.

[0034] like Figure 1 As shown, the belt 3 is fixed to the external rotating shaft and placed on the bottom plate 1; the bottom plate 1 is provided with a plurality of mounting holes for mounting the stainless steel plate 2, and the stainless steel plate 2 is provided with a plurality of fixing holes, each of which is provided with a boss 11. The mounting holes are provided with a first mounting hole 10 and a second mounting hole 9, the second mounting hole 9 and the first mounting hole 10 are in a connected structure, and the aperture of the first mounting hole 10 is larger than the diameter of the boss 11, and the aperture of the second mounting hole 9 is smaller than the diameter of the boss 11. When the stainless steel plate 2 is located in the first mounting area, the stainless steel plate 2 is in contact with the bottom plate 1; when the stainless steel plate 2 is located in the second mounting area, the boss 11 is in contact with the bottom plate 1.

[0035] The side positioning mechanism 7 and the paper feeding platform 8 are respectively screwed to the external wallboard, and the side positioning mechanism 7 is used for side positioning of the sheet object.

[0036] like Figure 2 As shown, when the edge of the sheet 6 made by the die-cutting machine is just at the edge of the belt 3, the sheet 6 is easily bent and uneven when it is positioned laterally, so that the positioning process hits the side of the belt 3, resulting in failure of side positioning. Figure 3As shown, in order to avoid side positioning failure, the screw 5 is loosened but the connection between the stainless steel plate 2 and the base plate 1 is not completely loosened, and the stainless steel plate 2 is manually lifted to move the stainless steel plate from the position of the second mounting hole 10 to the position of the first mounting hole 9, that is, the boss 11 contacts the base plate, thereby lifting the stainless steel plate 2, and finally, the nut plate 4, the base plate 1 and the stainless steel plate 2 are locked by tightening the screw 5. At this time, since the stainless steel plate 2 is higher than the belt 3, the sheet 6 can jump over the edge of the belt 3 during side positioning, thereby avoiding the problem of the edge of the sheet 6 hitting the belt 3.

[0037] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
