Sponge slicing method and sponge slicing fixing device for automobile cushion

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Such as Figure 1-4 As shown, the present invention is a sponge cutting method for car seat cushions, which includes a longitudinal cutting step and a transverse cutting step; when the longitudinal cutting is performed, the sponge is longitudinally flattened, and then the cutting device is used to longitudinally cut the flat sponge ; When performing transverse cutting, use an inflator to inflate the sponge. When the sponge is in a fully expanded state, use a cutting device to cut the sponge transversely.

[0024] Among them, it also includes a collection step, using a collecting device to collect the scraps generated during the cutting process to prevent the scraps from rising up and interfering with the normal operation of the equipment.

[0025] A sponge cutting and fixing device for automobile seat cushions includes a longitudinal cutting fixing mechanism 1 and a transverse cutting fixing mechanism 2; the longitudinal cutting fixing mechanism 1 is provided with a compression cylinder 101, the compression cylinder 101 is provided with a piston 102, and the inner wall of the compression cylinder 101 is also provided There is a sliding groove 103, the piston 102 is circumferentially provided with a sliding block 104 matching the sliding groove 103, the top of the piston 102 abuts the vertical rod 105, the top of the vertical rod 105 is connected to the hydraulic cylinder 106, and the middle of the piston 102 is provided with a strip through hole 107; The cutting and fixing mechanism 2 is provided with an inflator 201. The inflator 201 is provided with a longitudinally arranged fixed plate 202. The fixed plate 202 is connected to the inner wall of the inflator 201 through a spring 203. The top of the inflator 201 is provided with a cylinder cover 204, and the top of the cylinder cover 204 A connecting valve 205 is provided. The two ends of the connecting valve 205 are respectively connected to the inflator 306 and the tube 207. The end of the tube 207 is provided with an inflatable disk 208, the inflatable disk 208 is provided with air holes 209, and the inflatable disk 208 is also provided with a skirt rubber membrane 210. The top of the membrane 210 is sleeved at the end of the inflatable disk 208, and the end of the rubber membrane 210 is provided with a circumferentially distributed elastic band 211.

[0026] Wherein, a ball 108 is provided between the sliding groove 103 and the sliding block 104. When the sliding block 104 slides in the sliding groove 103, the rolling ball 108 can effectively reduce friction.

[0027] Among them, there is also a collection mechanism 3, the collection mechanism 3 is provided with a suction tube 301, which is connected to the air extractor 302, the end of the suction tube 301 is provided with an inward cone-shaped cover 303, and the middle of the cone-shaped cover 303 is provided The vent 304 prevents the debris generated in the cutting process from interfering with the stable operation of the equipment.

[0028] Among them, the air inlet of the air extractor 302 is provided with a filter 305 to prevent debris from entering the air extractor 302 to damage the equipment.

[0029] A specific application of this embodiment is: during longitudinal cutting, the hydraulic cylinder 106 presses against the piston 102 to flatten the sponge to be cut in the compression cylinder 101, and then cuts. When the piston 102 moves up and down in the compression cylinder 101, The sliding block 104 is displaced in the sliding groove 103 to ensure that the piston 102 remains level, which can avoid the displacement and deformation of the sponge during the cutting process; when cutting transversely, use the elastic band 211 to cover the rubber film 210 on the sponge to be cut. Open the connection valve 205, and the inflator 206 inflates the sponge. At this time, the sponge has a certain degree of hardness due to the inflation inside the sponge, and there will be no significant deformation during cutting. At the same time, the spring 203 squeezes the fixed plate 202 against the sponge. , To further realize the fixation; the above two methods improve the cutting accuracy of the sponge.
