In order to realize the purpose of the utility model, the utility model provides a following technical scheme:

the utility model provides a laser cutting and stripping device for cutting cloth, which comprises a device body and a first conveying mechanism arranged on the device body, wherein the device body is sequentially provided with a cutting station and a stripping station, and the first conveying mechanism conveys the cloth to the cutting station and the stripping station in sequence along a first conveying direction; a laser cutting mechanism is arranged above the cutting station, a stripping mechanism is arranged above the stripping station, and the laser cutting mechanism and the stripping mechanism are both connected with the device body in a sliding manner and slide along the first conveying direction; the peeling mechanism comprises a peeling rod, a downward pressing driving piece and a sliding driving piece, the sliding driving piece drives the peeling rod to slide along the first conveying direction, the downward pressing driving piece drives the peeling rod to be downward pressed or lifted up, and therefore the peeling rod is abutted to or separated from cloth on the first conveying mechanism. Laser cutting mechanism in this application is current conventional laser cutting mechanism, including the laser cutting head, and the setting of its structure and motion is not repeated here. Cloth in this application refers to a cloth, fabric or textile. The first conveying mechanism may be a conveyor belt, a conveyor roller, or the like. When the stripping rod is abutted against the cloth, the tail end of the stripping rod generates little extrusion towards the cloth.

The cloth slicing and stripping mechanism is additionally arranged on the laser cutting equipment, and the device body is provided with two stations which can simultaneously cut and strip cloth. The cloth is cut by the laser cutting head on the cutting station to obtain a cloth slice, the cloth slice is conveyed to the stripping station through the first conveying mechanism, and at the moment, the first conveying mechanism stops conveying. The rest cloth which is not cut is positioned on the cutting station, the cutting is continued by the laser cutting head, and meanwhile, the cloth slice positioned on the stripping station is stripped by the stripping mechanism. The stripping process is as follows: the sliding driving piece drives the stripping mechanism to reach the position above a cloth slice at the front end of the stripping station, the downward pressing driving piece drives the stripping rod to approach the surface of the first conveying mechanism until the stripping rod presses the cloth slice, the stripping mechanism is driven to reach the rear end/original point of the stripping station through the sliding driving piece while the cloth slice is pressed, and the cloth slice and the first conveying mechanism are stripped by utilizing the friction force between the stripping rod and the cloth slice. The driving piece is pressed downwards to drive the stripping rod to be far away from the surface of the first conveying mechanism, the stripping rod is lifted, and the cloth slices are transmitted to the first conveying terminal through the first conveying mechanism.

The distance between the stripping rod and the first conveying mechanism is controlled to be 1-2cm, so that the stripping rod can be pressed down quickly, a gap can be reserved for conveying of the cloth slices, and the cloth slices on the first conveying mechanism can pass through smoothly. Typically the cut piece of cloth is less than 3mm thick.

The material receiving mechanism is arranged at a first conveying terminal of the first conveying mechanism and comprises a turnover box connected with the first conveying terminal. The upper end face of the turnover box is lower than the surface of the first conveying mechanism or is flush with the surface of the first conveying mechanism. When first transport mechanism rotated the conveying, peeled off the cloth section and can directly fall into the turnover case and accomplish and receive the material, need not artifical the material of receiving. The operator does not need to bend down to put the piece goods into the bag, and the piece goods can be directly circulated by the turnover box.

The turnover boxes are conveyed on the second conveying mechanism, the weighing mechanism is installed at the bottoms of the turnover boxes, and when products in the turnover boxes at the first conveying terminal reach set weight, the second conveying mechanism conveys the next turnover box to the first conveying terminal. The operator does not need to additionally weigh the turnover box for collecting the cloth slices, namely the basket to be loaded, and when the previous basket to be loaded reaches the set numerical value weight, the basket to be loaded becomes a full basket. And the controller connected with the second conveying mechanism controls the second conveying mechanism to convey for a certain distance, and the next empty turnover box, namely the empty basket, is moved to the first conveying terminal to become a basket to be loaded.
