Description

Technical Field

[0001] This utility model belongs to the field of foam product manufacturing technology, and more specifically, it relates to a vacuum defoaming machine for foam product manufacturing. Background Technology

[0002] After foaming, car headrests and armrests often contain numerous closed air bubbles, causing the product to harden and lack elasticity. Therefore, a defoaming process is necessary to open and connect the internal foam pores, allowing the product to breathe and increasing its elasticity.

[0003] There are two main methods for breaking bubbles in foamed products: vacuum bubble breaking machines and physical crushing. Physical crushing typically uses rollers to crush the foamed product, but this method is not feasible when metal parts are attached to the product. In such cases, vacuum bubble breaking is necessary. However, existing vacuum bubble breaking processes simply create a vacuum in the environment surrounding the foamed product, resulting in slow bubble breaking speeds and potentially incomplete bubble breaking. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a vacuum bubble breaking machine for foamed product production, aiming to achieve greater practical value. Utility Model Content

Multiple sets of guide rods are slidably connected to the support base. A vacuum chamber is fixedly connected to the bottom end of the multiple sets of guide rods. The bottom side of the vacuum chamber has an opening for the foamed products to pass through. Guide rods are fixedly installed at the four corners of the top side of the inner wall of the vacuum chamber. A moving plate is slidably connected to the outer side of the guide rods. Multiple defoaming rods are fixedly installed at equal intervals on the bottom side of the moving plate. A connecting cylinder is fixedly connected to the bottom side of the moving plate on the outer side of the top of each defoaming rod. A limit ring is fixedly installed on one end of the connecting cylinder by fasteners. The limit ring is slidably connected to the outer side of the defoaming rod.

[0006] Furthermore, one end of the bubble-breaking rod is located inside the connecting cylinder and a limiting block is fixedly installed thereon. A spring is installed on the inner side of the connecting cylinder, and the two ends of the spring abut against one side of the inner wall of the connecting cylinder and one side of the limiting block, respectively.

[0007] Furthermore, the bottom end of the bubble-breaking rod is provided with a hemispherical surface.

[0008] Furthermore, a drive motor is fixedly installed on the top side of the inner wall of the vacuum chamber, and a rotating disk is fixedly installed on the output end of the drive motor. A connecting rod is eccentrically rotatably connected to the rotating disk. Connecting pins are rotatably connected to both sides of one end of the connecting rod via shafts. The bottom sides of both sets of connecting pins are fixedly connected to the top side of the moving plate.

[0009] Furthermore, a conveyor belt is fixedly installed on the main platform, and the conveyor belt is located on the bottom side of the vacuum chamber.

[0010] Furthermore, an electric cylinder is fixedly installed on the top side of the support base, and the output end of the electric cylinder passes through the support base and is fixedly connected to the top side of the vacuum chamber; a vacuum pump is fixedly installed on the top side of the support base, and a fixing pipe is fixedly installed on one side of the bottom end of the vacuum chamber. The fixing pipe is connected to the inside of the vacuum chamber, and a connecting pipe is fixedly connected to one end of the fixing pipe.

[0013] This invention, through the cooperation of a drive motor and a rotating disk, enables the flexible movement of a connecting rod. The cooperation of the connecting rod and connecting pins enables the flexible movement of a moving plate. The cooperation of the moving plate, connecting cylinder, and spring enables the striking of foamed products.

[0026] One end of the bubble-breaking rod 7 is located inside the connecting cylinder 8 and a limiting block 10 is fixedly installed thereon. A spring 11 is installed on the inner side of the connecting cylinder 8. The two ends of the spring 11 abut against one side of the inner wall of the connecting cylinder 8 and one side of the limiting block 10, respectively, so that the bubble-breaking rod 7 can apply pressure to break the bubbles in the foamed product.

[0027] The bottom end of the bubble-breaking rod 7 is provided with a hemispherical surface to prevent the bubble-breaking rod 7 from damaging the foamed product.

[0028] A drive motor 12 is fixedly installed on the top side of the inner wall of the vacuum chamber 4. A rotating disk 13 is fixedly installed on the output end of the drive motor 12. A connecting rod 14 is eccentrically connected to the rotating disk 13. Connecting pins 15 are rotatably connected to both sides of one end of the connecting rod 14 via shafts. The bottom sides of both sets of connecting pins 15 are fixedly connected to the top side of the moving plate 6, which can realize the automatic and flexible movement of the moving plate 6.

[0029] The main platform 1 is fixedly equipped with a conveyor belt 16, which is located on the bottom side of the vacuum box 4, and can realize flexible transfer of foamed products.

[0030] An electric cylinder 17 is fixedly installed on the top side of the support base 2.

Thus, physical defoaming and vacuum defoaming are performed on the foamed product at the same time, increasing the defoaming efficiency of the product.
