[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-3 A vacuum rolling foam breaking device for automobile seat foaming comprises a conveyor belt 1 and a vacuum box 3. A bottom support 2 is arranged at the bottom of the conveyor belt 1. Side panels 4 are fixedly installed on both sides of the vacuum box 3. Two electric push rods 5 are symmetrically fixedly installed on the side panels 4. The lower ends of the electric push rods 5 are fixedly connected to the upper side of the lateral support body of the conveyor belt 1. A control main board 6 is installed on the side wall of the vacuum box 3. An air inlet 7 and a vacuum pump 8 are arranged on the upper side of the vacuum box 3. The air inlet 7 is connected to the inside of the vacuum box 3 and an electromagnetic valve 10 is installed inside the air inlet 7. The vacuum pump 8 is screwed on the upper side of the vacuum box 3 by bolts and the vacuum pump 8 exhaust end is connected to the vacuum box 3. The inside of the box 3 is connected, the air outlet end of the vacuum pump 8 is connected to the air outlet pipe 9, a sealing ring 12 is installed at the bottom of the vacuum box 3, a hydraulic rod 13 is fixedly installed at the top of the inside of the vacuum box 3, an upper groove plate 14 is fixedly connected to the output end of the hydraulic rod 13, a lower groove plate 15 is slidably sleeved at the bottom of the upper groove plate 14, a number of groups of compression springs 17 are fixedly installed between the upper groove plate 14 and the lower groove plate 15, shaft seats 18 are symmetrically installed on both sides of the bottom of the lower groove plate 15, a rotating shaft 19 is rotatably installed between the two shaft seats 18, a pressure roller 20 is fixedly sleeved on the outside of the rotating shaft 19, and three groups of shaft seats 18, rotating shafts 19 and pressure rollers 20 are respectively provided.
[0020] Through the above structure, the electric push rod 5 is started to contract so that the sealing ring 12 at the bottom of the vacuum box 3 is close to the upper side of the conveyor belt 1, and the air inlet 7 is closed, so that the interior of the vacuum box 3 is in a closed state, and the vacuum pump 8 is subsequently started to extract the air inside the vacuum box 3, that is, the vacuum box 3 is kept in a vacuum state, so that the vacuum box 3 has a vacuum defoaming effect on the automobile foam pad, and the hydraulic rod 13 is subsequently started to drive the pressure roller 20 to move downward to roll the automobile foam pad to discharge the bubbles inside the automobile foam pad, so that the automobile foam pad has high cushioning and low elasticity.
[0021] In this embodiment, an air pressure sensor 11 is installed on the inner side wall of the vacuum box 3 , and the air pressure sensor 11 is electrically connected to the control mainboard 6 .
[0022] Through the above structure, the air pressure sensor 11 monitors the air pressure conditions of the vacuum box 3 when it is working in real time, and feeds back the air pressure conditions to the control main board 6 for display. When the air pressure value increases, the control main board 6 will continue to start the vacuum pump 8 to draw the air pressure inside the vacuum box 3 to a vacuum state, thereby ensuring the vacuum degassing performance of the vacuum box 3.
[0023] In this embodiment, the inner wall of the vacuum box 3 is symmetrically provided with slide grooves 16 , and both the upper groove plate 14 and the lower groove plate 15 are in sliding contact with the slide grooves 16 .
[0024] Through the above structure, the opening of the slide groove 16 makes it more stable when the hydraulic rod 13 drives the upper groove plate 14 and the lower groove plate 15 to move up and down.
[0025] In this embodiment, the sealing ring 12 is a hollow arc-surface sealing rubber strip and the sealing ring 12 is arranged along the bottom of the vacuum box 3 in a circle.
[0026] Through the above structure, the sealing ring 12 is designed as a hollow arc-surface sealing rubber strip, so that when the bottom of the sealing ring 12 contacts the upper side of the conveyor belt 1, it is easier to fit with the conveyor belt 1, thereby providing a guarantee for the sealing performance of the vacuum box 3.
[0027] In the utility model, when in use, when the conveyor belt 1 conveys the automobile foam pad to the bottom of the vacuum box 3, the driving is stopped, the electric push rod 5 contracts to drive the vacuum box 3 to move downward and make the sealing ring 12 at the bottom of the vacuum box 3 close to the upper side of the conveyor belt 1, and the electromagnetic valve 10 in the air inlet 7 is closed. At this time, the interior of the vacuum box 3 is in a closed state, and the vacuum pump 8 is subsequently started to work to extract the air inside the vacuum box 3 and discharge it from the air outlet pipe 9, that is, the interior of the vacuum box 3 is kept in a vacuum state. In the vacuum state, the bubbles inside the automobile foam pad are Due to the effect of the air pressure difference, the air overflows into the vacuum box 3, and is finally discharged from the vacuum box 3 under the action of the vacuum pump 8. Subsequently, the hydraulic rod 13 is started to drive the pressure roller 20 to move downward to roll the automobile foam pad to discharge the bubbles inside the automobile foam pad that are difficult to overflow. After the rolling is completed, the hydraulic rod 13 retracts to drive the pressure roller 20 to move upward, and then the electromagnetic valve 10 is opened, and the air inlet 7 starts to take in air. Then the electric push rod 5 is extended to lift the vacuum box 3, and finally the conveyor belt 1 is started to transport the processed automobile foam pad to the next process. The above is the working process and principle of the utility model. The utility model uses the telescopic distance of the hydraulic rod 13 to adjust the distance between the pressure roller 20 and the top surface of the conveyor belt 1, so as to be suitable for the rolling work of automobile foam pads of different thicknesses or sizes, thereby improving the applicability of the equipment. In addition, a plurality of groups of compression springs 17 are arranged between the lower groove plate 15 and the upper groove plate 14, so that the force transmission system between the upper groove plate 14 and the lower groove plate 15 has an elastic buffering effect, so that the pressure roller 20 has an elastic rolling effect when acting on the foam pad, thereby avoiding the rolling damage caused by rigid rolling, thereby enhancing the practicality of the equipment.
