Multi-layer backing plate of sawing machine

Abstract

The utility model discloses a multilayer backing plate of a sawing machine. The multilayer backing plate is provided with a bottom supporting layer, a middle bearing layer and a surface sawing layer which are arranged from bottom to top. The middle bearing layer and the surface sawing layer are thinner and are fixedly connected together to form a two-layer composite board; the two ends of the two layers of composite boards are each provided with a kidney-shaped hole, a bolt can be inserted into each kidney-shaped hole and connected with a nut embedded in the bottom supporting layer in a screwed mode, and therefore the three layers are connected into a whole in a fastened mode. The thicker bottom supporting layer cannot be sawn, so that the service life is prolonged; the two thin layers of composite boards can be replaced, so that waste is reduced; and during replacement, the surface sawing layer is not scattered and disordered.

Description

Technical Field

[0001] The utility model relates to a structural shape of a backing plate for a sawing machine. Background Art

[0002] The cutting board is one of the necessary tools for a saw or paper cutter. It has the following uses: 1) Protect the saw blade or blade and extend its service life; 2) Protect the desktop to prevent it from being scratched or contaminated by various sharp tools; 3) Make cutting convenient, and you can easily cut a straight line on the cutting board without even using a steel ruler.

[0003] The cutting board should be thick to ensure the long-term use of the saw blade or blade, and the service life of the cutting board itself is also long. However, after the common cutting board has many sawing grooves, it needs to be replaced as a whole, which wastes a lot of materials. Summary of the invention

[0004] Purpose of the utility model:

[0005] The invention provides a sawing machine multi-layer pad which can save material consumption and reduce replacement frequency.

[0006] Technical solution:

[0007] The utility model provides a multi-layer pad for a sawing machine, which is matched with sawing machines such as sawing machines or paper cutters.

[0008] It has a bottom supporting layer, a middle bearing layer and a surface sawing layer which are arranged from bottom to top.

[0009] The intermediate bearing layer and the surface sawing layer are both relatively thin (3-50 mm thick), and are fixedly connected (such as glued) together to form two layers of composite boards; then the two layers of composite boards are movably connected to the thicker bottom supporting layer.

[0010] The bottom supporting layer is a continuous plate with the thickest thickness (50-500mm) and can bear the weight of heavier materials.

[0011] The middle bearing layer is a continuous plate material; the surface sawing layer is composed of parallel arranged sawing plates which are divided into 2 or more pieces or are divided into 2 or more pieces by the saw blade when in use, and there is a sawing groove with a width of 2-60mm between adjacent sawing plates (the thickness of the saw blade can be 2-6mm, and the sawing groove is formed by sawing of successive or multiple layers of saw blades; the depth of the saw blade or blade during sawing is not greater than the thickness of the surface sawing layer, and due to the different depth of each sawing, the depth of the bottom of the sawing groove may be different).

[0012] When the saw blade located above the material (the plane where the saw blade is located is perpendicular to the multi-layer pad of the sawing machine, and is located above the sawing groove formed by subsequent sawing, and is parallel to the edge of the sawing groove) starts to saw the material, the saw blade saws the material from top to bottom, and when the material is about to be cut off, the saw blade will be exposed from the bottom of the material after sawing the material, realizing the sawing and separation of the material. The exposed saw teeth or blades will saw the surface sawing layer and form a sawing groove on the surface sawing layer.

[0013] There is a waist-shaped hole at each end of the sawing machine multi-layer pad (along the length direction of the sawing machine multi-layer pad), which penetrates the surface sawing layer and the middle bearing layer, that is, penetrates the two layers of composite board. A bolt can be inserted into the waist-shaped hole, and the bolt can be screwed to the nut embedded on the bottom supporting layer, so that the three layers are fastened and connected into a whole, and the material to be sawed is placed on the top.

[0014] By adjusting the position of the bolt in the waist-shaped hole, the two layers of composite panels can be moved left and right, while the bottom supporting layer does not move; the material to be sawed is placed on the multi-layer pad of the sawing machine, and sawing grooves are formed at the same or different positions on the surface sawing layer during sawing.

[0015] When there are too many sawing grooves on the surface sawing layer or they are too wide, so that the material may fall into the sawing grooves when it is placed, resulting in unstable placement, it is necessary to loosen the bolts in the waist-shaped holes that are screwed to the bottom supporting layer. Only two layers of composite boards need to be replaced (at this time, the middle bearing layer ensures that the several plates of the surface sawing layer will not separate and scatter, making it easy to take them away together), and there is no need to replace the thicker bottom supporting layer.

[0016] Beneficial effects:

[0017] The utility model can provide support for the material being cut, and can also make the material be completely sawed through and separated during cutting; and the bottom support layer will not be sawed, thereby extending the service life. Only a very thin surface sawing layer is sawed to form a sawing groove, and then the surface sawing layer can be driven to move left and right within the length of the waist-shaped hole to adjust the position of the sawing groove; and then it can be used in a matching sawing machine again to saw new materials and form new sawing grooves. When there are too many sawing grooves on the surface sawing layer, which affects the padding of subsequent materials, the two-layer composite board of the new intermediate bearing layer and the surface sawing layer can be replaced, which not only does not affect the sawing quality of the material, but also greatly saves the cost of using the multi-layer pad of the sawing machine and reduces waste.

[0021] like Figure 1 , 2 The multi-layer pad of the sawing machine shown in the figure has a bottom supporting layer 1, an intermediate bearing layer 2, and a surface sawing layer 3 arranged from bottom to top. The intermediate bearing layer 2 and the surface sawing layer 3 are relatively thin, both of which are about 10 mm thick. The two are fixedly connected together to form two layers of composite panels; then the two layers of composite panels are movably connected to the bottom supporting layer 1 with a thickness of 100 mm.

[0022] The middle bearing layer 2 is a continuous plate material; the surface sawing layer 3 is composed of sawing plates which are divided into three pieces or are divided into three pieces by contact with a saw blade when in use, and there are sawing grooves 6 with a width of about 30 mm between adjacent sawing plates.

[0023] There are waist-shaped holes 4 and 5 with a length of 12-30 mm at both ends of the sawing machine multi-layer pad, respectively. The waist-shaped holes 4 and 5 penetrate the two layers of composite plates. A bolt 7 can be inserted into the waist-shaped holes 4 and 5, and the bolt 7 can be screwed to the nut embedded on the bottom support layer 1, so that the three layers are fastened and connected into a whole. Figure 1 As shown, the two layers of composite sheet material extend out of the bottom support layer 1 from the left side; the screw connection position of the bolt 7 in the waist-shaped holes 4 and 5 can also be adjusted to become as shown in FIG. Figure 2 As shown, the two layers of composite board extend from the bottom support layer 1. When moving left and right, the positions of the sawing grooves 6 formed on the surface sawing layer 3 are different.
