Description

Technical Field

[0001] This utility model relates to the field of garment machinery, specifically to a negative pressure device for a cutting machine and the cutting machine itself. Background Technology

[0002] In the garment manufacturing process, the whole piece of material to be cut needs to be cut into pieces of different shapes. In order to improve the cutting efficiency of the material, the current cutting machine uses a negative pressure adsorption unit to adsorb the material on the plate to prevent the material from moving during cutting. However, most of these negative pressure devices are concentrated in one negative pressure chamber and cannot concentrate on strengthening the adsorption of a certain area. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a negative pressure device for a cutting machine, which mainly solves the problem that the current negative pressure devices of cutting machines cannot concentrate on strengthening the adsorption of a certain area.

[0004] The technical solution of this utility model is as follows:

[0005] A negative pressure device for a cutting machine includes a first housing and a second housing. The first housing has a plurality of air holes and further includes...

[0006] Several independent negative pressure chambers are disposed within the first housing, and each negative pressure chamber is connected to at least one air vent.

[0007] A cavity is provided inside the second housing and is connected to a negative pressure source, and is connected to a plurality of conduits, one of the conduits being connected to one of the negative pressure cavities;

[0008] Several air valves are installed on the second housing for opening and closing at least one of the conduits.

[0009] The air valve includes a linear actuator and a plug driven by the linear actuator, the plug having a first position blocking the conduit and a second position away from the conduit.

[0010] The linear actuator is a hydraulic cylinder or a pneumatic cylinder.

[0011] The second housing has two parts.

[0012] The first housing is provided with several baffles, which divide the inner cavity of the first housing into several negative pressure cavities.

[0013] A cutting machine includes a frame on which a negative pressure device as described above is mounted.

[0014] The beneficial effects of this utility model are: This utility model provides a negative pressure device for a cutting machine, which divides the first housing into multiple independent negative pressure chambers. The suction force of the open negative pressure chambers can be strengthened by closing non-critical areas, thus meeting different practical needs. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings: As shown in the figures, a negative pressure device for a cutting machine includes a first housing 1 and a second housing 2. The first housing is provided with a plurality of air holes 11 and includes a plurality of independent negative pressure chambers 12 disposed within the first housing, and each negative pressure chamber is connected to at least one air hole; a cavity 21 is disposed within the second housing and is connected to a negative pressure source, and is connected to a plurality of conduits 131, one of the conduits being connected to one of the negative pressure chambers; a plurality of air valves 3 are installed on the second housing for opening and closing at least one of the conduits. If it is necessary to enhance the adsorption capacity in a certain area, the conduits in other areas can be appropriately closed, so that the adsorption capacity of the unclosed local chambers is enhanced while the total adsorption force remains unchanged. Furthermore, one air valve is used to control one conduit, thereby controlling one negative pressure chamber.

[0020] In this embodiment, as shown in the figure, the air valve includes a linear actuator 31 and a plug 32 driven by the linear actuator. The plug has a first position blocking the conduit and a second position away from the conduit. When the plug is active, it can switch between blocking and opening the conduit to open and close the conduit. The structure is relatively simple, with each linear actuator driving one plug to open and close one negative pressure chamber.

[0021] In this embodiment, as shown in the figure, the linear actuator is a hydraulic cylinder or a pneumatic cylinder.

[0022] In this embodiment, as shown in the figure, there are two second housings, one on each side. This way, half of the first housing is handled by one side, and the conduit does not need to be very long.

[0023] In this embodiment, as shown in the figure, the first housing is provided with a plurality of baffles 13, which divide the inner cavity of the first housing into a plurality of negative pressure chambers. Dividing the first housing into multiple negative pressure chambers by the baffles results in a relatively simple structure.

[0024] In this embodiment, as shown in the figure, a cutting machine includes a frame 5, on which a negative pressure device for a cutting machine as described above is mounted. The device can be installed on the frame using screws or similar means.
