Description

Technical Field

[0001] The utility model relates to the technical field of the process technology for laying floor cloth on the floor of a multiple unit train, in particular to a cutting device for the floor cloth of a multiple unit train. Background Art

[0002] Floor cloth is laid on the floor of a multiple unit train. The connection between the floor cloth and the bottom plate is achieved by bonding with glue. Taking the seat profile bracket on the side wall of the car body as the critical point, the floor cloth is bonded below the seat profile bracket and the side wall panel is installed above.

[0003] The process requirements for bonding the floor cloth require that the upper edge of the floor cloth be placed inside the cavity of the lower edge of the seat profile bracket. When the floor cloth is bonded below the seat profile bracket, the excess floor cloth needs to be cut.

[0004] At present, the floor cloth is cut on the vehicle. It is ensured that the upper edge of the cut floor cloth can be placed inside the cavity below the seat profile bracket to ensure that the floor cloth does not leak out. The length of the seat profile bracket of a multiple unit train is 20 meters, and the total length on both sides inside the carriage is 40 meters. The cutting of the floor cloth below the seat cavity bracket is particularly crucial because the floor cloth is laid from the center line of the car body to both sides of the car body side wall. Therefore, the cutting of the floor cloth below the seat cavity bracket is the last process. If the cutting allowance is too large, the floor cloth cannot be placed inside the cavity below the seat cavity bracket. If the cutting allowance is too small, the lower edge of the seat cavity bracket cannot cover the upper edge of the floor cloth.

[0005] In the prior art, the general operation method requires 3 operators to complete it together. 2 operators respectively hold a steel ruler on the floor cloth, and 1 operator uses a wallpaper knife to cut the floor cloth along the edge path of the steel ruler. This operation requires the personal actions of the operators controlling the steel ruler to be coordinated. The pressure on the steel ruler should be large. At the same time, since the cutting path of the wallpaper knife held by the operator is controlled by the operator's wrist, the cutting path is prone to deviation, and it is easy to make cutting mistakes due to the cooperation of multiple people in the operation process. Therefore, this kind of operation has too high requirements for the skills of the operators, low production efficiency, and the risk of material loss due to cutting mistakes.

[0006] Therefore, based on the above technical problems, those skilled in the art urgently need to develop a cutting device for the floor cloth of a multiple unit train. Content of the Utility Model
