Description

Saw machine

The present invention relates to a cutting device, in particular to a sawing machine.

An existing sawing machine includes an upright base unit, a cutting unit disposed in the base unit, and a conveying unit passing through the base unit along a front-to-back direction. The base unit has a base body and a channel passing through the base body. The cutting unit has two cutting belts disposed in the base body at intervals along a vertical direction perpendicular to the front-to-back direction, and each cutting belt is used to cut a material along the front-to-back direction. The conveying unit includes a conveying belt extending along the front-to-back direction and passing through the channel.

In actual use, the material is placed on the front side of the conveyor belt relative to the base body. The conveyor belt is operated to drive the material to move toward the rear side along the front-rear direction, and the material approaches and contacts the cutting belts, and is then cut into three sections: upper, middle, and lower. The cut material continues to be driven by the conveyor belt until it passes through the channel, completing the cutting operation.

However, when the existing sawing machine is actually used, the material scraps generated when cutting the material will be attached to the cutting belt and the conveyor belt, which takes time to clean. It is also more likely that the friction between the conveyor belt and the material is insufficient, causing the material to slip when the cutting belt cuts the material, resulting in poor cutting results, which directly affects the accuracy of the cutting operation. Obviously, there is still room for improvement in the existing sawing machine.

Therefore, the purpose of the present invention is to provide a sawing machine that can overcome the above-mentioned shortcomings.

Therefore, the sawing machine of the present invention is suitable for cutting a material. The sawing machine includes a base unit, a conveying unit, a cutting unit and a cleaning unit. The base unit includes a substrate that is vertically arranged and has an internal space, and a channel that penetrates the substrate along a front-to-back direction. The conveying unit includes a conveying module that extends along the front-to-back direction and is located corresponding to the channel, and a rubber strip that is arranged on the conveying module along an up-down direction perpendicular to the front-to-back direction. The conveying unit is used for placing the material and allowing the material to be vacuum-adsorbed on the conveying module and the rubber strip to drive the material through the channel. The cutting unit is located in the internal space and above the conveying module along the up-down direction. The cutting unit is used to cut the material along the front-back direction so that the material is divided into an upper layer and a lower layer below the upper layer. The cleaning unit is located in the internal space and adjacent to the cutting unit. The cleaning unit is used to clean the part of the material that is left in the cutting unit when the material is cut by the cutting unit.

The effect of the present invention is that the conveying module and the rubber strip are provided to jointly adsorb the material, thereby improving the adsorption effect of the conveying unit when conveying the material, and the cleaning unit is provided to clean the part of the material left in the cutting unit when the material is cut by the cutting unit, thereby improving the sharpness of the cutting unit and jointly improving the cutting accuracy of the sawing machine of the present invention.
