Description

Technical Field

[0001] This utility model relates to the field of garment machinery, specifically to a negative pressure device for a side-mounted cutting machine. 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.

[0003] To this end, Chinese Patent Application No. 2024230076282 describes a negative pressure device for a cutting machine. However, this device uses a bottom-mounted cylinder, and the space below the second housing is very narrow, which is not conducive to maintenance and disassembly. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a side-mounted negative pressure device for a cutting machine, which mainly solves the problem that the negative pressure device of a conventional cutting machine adopts a bottom-mounted structure, which is not conducive to maintenance and disassembly.

[0005] The technical solution of this utility model is as follows:

[0006] A negative pressure device for a side-mounted cutting machine includes a first housing and a second housing. The first housing has a plurality of air vents and a plurality of independent negative pressure chambers, each of which communicates with at least one air vent. One end of the second housing is connected to a negative pressure source, and the other end is connected to a negative pressure chamber via a conduit. The second housing includes...

[0007] A base, wherein the base has a cavity that is connected to the negative pressure source;

[0008] The side cover is detachably connected to the side end face of the base;

[0009] Several air valves are installed on the side of the side cover facing the cavity, and are placed inside the cavity after installation. The air valves are used to control the opening and closing of the conduit.

[0010] 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.

[0011] The linear actuator is a cylinder.

[0012] The outer wall of the side cover is provided with a connector for the passage of the cylinder's air pipe.

[0013] The side cover is connected to the base by screws.

[0014] The side cover is provided with a support plate, and the air valve is installed on the support plate.

[0015] The bottom of the support plate is equipped with a reinforcing plate.

[0016] The reinforcing plate is arranged perpendicularly to the supporting plate.

[0019] Figure 2 This is a partial cross-sectional view of one embodiment of the present invention.

[0020] Figure 3 This is a partial perspective view of one embodiment of the present invention. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings. A negative pressure device for a side-mounted 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 a plurality of independent negative pressure chambers 12 are provided inside the first housing. Each negative pressure chamber is connected to at least one air hole. One end of the second housing is connected to a negative pressure source, and the other end is connected to a negative pressure chamber through a conduit 13. The second housing includes a base 21, in which a cavity 211 is provided, and the cavity is connected to the negative pressure source. A side cover 22 is detachably connected to the side end face of the base. A plurality of air valves 3 are installed on the side of the side cover facing the cavity and are located inside the cavity after installation. The air valves are used to control the opening and closing of the conduit. The principle is similar to that of Chinese Patent Application No. 2024230076282: each air valve controls one conduit, and each conduit connects to a negative pressure chamber, thus achieving one-to-one control. If enhanced adsorption capacity is needed in a certain area, conduits in other areas can be appropriately closed. This strengthens the adsorption capacity of the unclosed local chambers while maintaining the total adsorption force. Furthermore, one air valve controls one conduit, which in turn controls one negative pressure chamber. The difference is that the air valves in this application are mounted on the side cover and can be removed together with the side cover for easy maintenance.

[0022] 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.

[0023] In this embodiment, as shown in the figure, the linear actuator is a cylinder.

[0024] In this embodiment, as shown in the figure, the outer wall of the side cover is provided with a connector 222, which is used for the passage of the cylinder's air pipe. A sealing ring can be provided on the inner wall of the connector, and the air pipe passes through the sealing ring, which can greatly increase the airtightness.

[0025] In this embodiment, as shown in the figure, the side cover is connected to the base by screws. The side cover is provided with screw mounting holes 20 for connection and installation.

[0026] In this embodiment, as shown in the figure, a support plate 224 is provided on the side cover, and the air valve is mounted on the support plate. It can be mounted on the support plate using screws or other means.

[0027] In this embodiment, as shown in the figure, a reinforcing plate 225 is provided at the bottom of the support plate. This increases the load-bearing capacity and prevents breakage.

[0028] In this embodiment, as shown in the figure, the reinforcing plate is arranged perpendicularly to the supporting plate.
