Technical Field
[0001] This utility model relates to the field of automotive seat foam production technology, and in particular to a vacuum and mechanical dual-purpose foam breaking device for automotive seat foam. Background Technology
[0002] During the production of car seat foam, the expansion of closed-cell foam can cause the foam to deform. Therefore, it is necessary to de-bubble the foam as soon as it is produced.
[0003] However, the traditional method involves manually breaking the bubbles in the sponge, which takes an average of 30 seconds per sponge. This method is slow, labor-intensive, and wastes manpower. Utility Model Content
[0004] The purpose of this invention is to provide a vacuum and mechanical dual-purpose bubble-breaking device for automotive seat foam, which aims to solve the technical problems of the traditional method of manually breaking bubbles in the foam, which requires 30 seconds of knocking on an average of one foam. This method is slow, labor-intensive, and wasteful of manpower.
[0005] To achieve the above objectives, this utility model employs a dual-purpose vacuum and mechanical foam breaking device for automotive seat foam, comprising an upper conveyor belt, a lower conveyor belt, a vacuum chamber, and a frame. The upper conveyor belt is driven by an upper turbine reducer. The lower conveyor belt is equipped with multiple rollers, which are connected to the rollers via sprockets and chains. One of the sprockets is driven by the lower turbine reducer. A fixed frame is provided on the frame, and two vacuum pumps and two lifting cylinders are mounted on the fixed frame. Each vacuum pump is equipped with a venting valve and a vacuum valve. The upper conveyor belt is fixedly connected to the frame and located in the middle of the frame. The lower conveyor belt is fixedly connected to the frame and located at the bottom of the frame. The vacuum chamber is fixedly connected to the corresponding lifting cylinder and located at the output end of the two lifting cylinders, and also above the upper conveyor belt. The vacuum pump ends of both vacuum pumps are connected to the vacuum chamber and located above the vacuum chamber.
[0006] The lower conveyor belt is divided into a front conveyor belt and a rear conveyor belt, and multiple rollers are arranged on the rear conveyor belt.
[0007] The multiple rolls are divided into multiple upper rolls and multiple lower rolls, and a mechanical defoaming chamber is formed between the multiple upper rolls and the multiple lower rolls.
[0008] A vacuum bubble-breaking chamber is formed between the vacuum box and the upper conveyor belt.
[0009] The automotive seat foam vacuum mechanical dual-purpose foam breaking device also includes multiple balancing racks and multiple rotating rods. Each of the rotating rods has a bevel gear at both ends. The multiple balancing racks are fixedly connected to the frame and located on the inner side of the frame. The multiple rotating rods are rotatably connected to the vacuum box through bearings and are symmetrically arranged on the outer side of the vacuum box. Two bevel gears mesh with the corresponding balancing racks and are located on the corresponding two balancing racks.
[0010] This utility model discloses a dual-purpose vacuum and mechanical bubble-breaking device for automotive seat foam, comprising an upper conveyor belt, a lower conveyor belt, a vacuum chamber, and a frame. Multiple rollers are mounted on the lower conveyor belt, and a fixed frame is mounted on the frame. Two vacuum pumps and two lifting cylinders are mounted on the fixed frame. The vacuum pumps are equipped with venting valves and vacuum valves, creating a vacuum environment that causes the bubbles inside the foam to automatically expand and burst. The lower layer is for mechanical bubble breaking, utilizing the lower conveyor belt and multiple rollers. Mechanical bubble breaking is achieved through the compression of the upper and lower rollers. The device features a specially designed balance rack and rotating rod mechanism to ensure the stability of the vacuum chamber during lifting. This device not only significantly improves bubble-breaking efficiency (mechanical bubble breaking cycle 10s / bubble, vacuum bubble breaking cycle 20s / bubble) but also greatly reduces the labor intensity of workers; one device can replace the workload of two workers, effectively saving labor costs.

Detailed Implementation
[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0016] Please see Figures 1-2 This utility model provides a dual-purpose vacuum and mechanical foam breaking device for automotive seat foam, including an upper conveyor belt 1, a lower conveyor belt, a vacuum chamber 3, and a frame 4. The upper conveyor belt 1 is driven by an upper worm gear reducer 5. The lower conveyor belt is equipped with multiple rollers, and the lower conveyor belt and the multiple rollers are connected by sprockets 7 and chains 8. One of the sprockets 7 is driven by a lower worm gear reducer 9. The frame 4 is equipped with a fixing frame 10, and the fixing frame 10 is equipped with two vacuum pumps 11 and two lifting cylinders. 12. The vacuum pump 11 is equipped with a venting valve 13 and a vacuum valve. The upper conveyor belt 1 is fixedly connected to the frame 4 and is located in the middle of the frame 4. The lower conveyor belt is fixedly connected to the frame 4 and is located at the bottom of the frame 4. The vacuum box 3 is fixedly connected to the corresponding lifting cylinder 12 and is located at the output end of the two lifting cylinders 12, and is also located above the upper conveyor belt 1. The vacuum pump ends of the two vacuum pumps 11 are connected to the vacuum box 3 and are located above the vacuum box 3.
[0017] In this embodiment, by integrating vacuum debubbling and mechanical debubbling functions, the automated debubbling process of the sponge is realized, which significantly improves the debubbling efficiency, reduces the labor intensity of workers, and saves labor costs. The upper conveyor belt 1 and the lower conveyor belt enable the sponge to move smoothly in the equipment to complete the debubbling process; the cooperation between the vacuum box 3 and the vacuum pump 11 ensures the smooth operation of vacuum debubbling.
[0018] Furthermore, the lower conveyor belt is divided into a front conveyor belt 14 and a rear conveyor belt 2, and a plurality of the rollers are arranged on the rear conveyor belt 2.
[0019] In this embodiment, the sponge is initially conveyed by the front conveyor belt 14, and the rollers on the rear conveyor belt 2 mechanically break the bubbles in the sponge, so that the sponge can maintain a stable moving speed when passing through the mechanical bubble breaking, thereby improving the consistency and stability of the bubble breaking effect.
[0020] Furthermore, the plurality of rolls are divided into a plurality of upper rolls 6 and a plurality of lower rolls 15, and a mechanical debubbling chamber is formed between the plurality of upper rolls 6 and the plurality of lower rolls 15.
[0021] In this embodiment, the sponge is squeezed from all directions by the cooperation of the upper and lower rollers 15, which allows the air bubbles inside the sponge to be squeezed and burst more effectively, thereby improving the efficiency and effect of mechanical bubble breaking. At the same time, the formation of the mechanical bubble breaking chamber also ensures the stability and safety of the sponge during the bubble breaking process.
[0022] Furthermore, a vacuum bubble-breaking chamber is formed between the vacuum box 3 and the upper conveyor belt 1.
[0023] In this embodiment, by forming a closed vacuum rupture chamber, the sponge can automatically expand and crack in a vacuum environment, thus completing the rupture process.
[0024] Furthermore, the dual-purpose vacuum and mechanical foam breaking device for automotive seat foam also includes multiple balancing racks 16 and multiple rotating rods 17. Each end of the rotating rod 17 is provided with a bevel gear 18. The multiple balancing racks 16 are respectively fixedly connected to the frame 4 and located on the inner side of the frame 4. The multiple rotating rods 17 are respectively rotatably connected to the vacuum box 3 through bearings and are symmetrically arranged on the outer side of the vacuum box 3. The two bevel gears 18 respectively mesh with the corresponding balancing racks 16 and are located on the corresponding two balancing racks 16.
[0025] In this embodiment, the stability and balance of the vacuum box 3 during the lifting and lowering process are ensured by the cooperation of the balance rack 16, the bevel gear 18 and the rotating rod 17. This design avoids the shaking or tilting of the vacuum box 3 due to uneven force during the lifting and lowering process, improves the overall stability and reliability of the equipment, and also extends the service life of the equipment and reduces maintenance costs.
[0026] In this invention, for foamed parts with a steel wire skeleton, the foamed part is manually placed on the upper conveyor belt 1. The upper turbine reducer 5 drives the upper conveyor belt 1 to send the foamed part into the vacuum chamber 3. When the photoelectric switch detects that the foamed part has arrived (this photoelectric switch detection is existing technology, and its specific working principle and position will not be described here), the upper conveyor belt 1 stops, and the vacuum chamber 3 descends under the action of the lifting cylinder 12 to form a sealed cavity. The vacuum pump 11 starts working, and through the automatic control of the vacuum valve and the venting valve 13, the vacuum chamber is opened in a vacuum environment. The foamed part is made to automatically expand and burst the air bubbles inside, completing the vacuum defoaming process. Then, the vacuum box 3 is lifted, and the upper conveyor belt 1 continues to run to send the foamed part out. For foamed parts without steel wire skeleton, they are manually fed into the front conveyor belt 14 and pass through the mechanical defoaming chamber formed by multiple upper rollers 6 and lower rollers 15. Mechanical defoaming is completed under the extrusion of the upper and lower rollers. Then, they are sent out by the rear conveyor belt 2 to the next process. Throughout the process, the balance rack 16, the sector gear and the rotating rod 17 ensure that the vacuum box 3 is lifted and lowered smoothly, ensuring the stable operation of the equipment.
[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
