Description

Technical Field

[0001] The utility model relates to the technical field of foaming devices, in particular to a memory cotton foaming device. Background Art

[0002] Memory foam pillows are also called space memory pillows, zero-pressure memory pillows, slow-rebound sponge pillows, polyether polyurethane pillows, etc. They have the function of absorbing impact. When you lie on them, you feel like floating on water or in the clouds, and your skin feels no pressure. The pillows are made of natural latex foamed by a latex foaming machine, and then mechanically injected into a pre-prepared mold. After vulcanization and drying, the latex is made into a pillow shape. The principle of the latex foaming machine is to mix natural latex and a foaming agent, introduce air into the foaming machine's water solution and stir to achieve uniform dispersion, so that the liquid and gas form the largest possible contact surface, so that the surfactant in the foaming agent forms a double layer on the surface of the liquid film and surrounds the air to form bubbles.

[0003] However, in the existing foaming equipment, when natural latex and foaming agent are added to the foaming tank for stirring and mixing, a small amount of natural latex will adhere to the inner wall of the foaming tank, resulting in incomplete mixing of the natural latex and foaming agent. The resulting latex liquid will have poor quality or even be scrapped due to the imbalance in proportions. Moreover, after the latex adheres to the inner wall of the foaming tank and condenses into lumps, it is difficult to clean, affecting the subsequent use of the equipment.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0027] like Figures 1 to 5 As shown, the utility model is a memory foam device, comprising: a base 1, a foaming barrel 9 fixedly mounted on the top of the base 1, a cover plate 8 attached to the top of the foaming barrel 9, a stirring mechanism for stirring natural latex and foaming agent, and a lifting mechanism for driving the stirring mechanism to move up and down.

[0028] The lifting mechanism includes: an installation box 2 fixedly installed on the top of the base 1, a threaded rod 4 rotatably installed on the installation box 2, a first motor 3 that drives the threaded rod 4 to rotate, a threaded tube 5 threadedly connected to the threaded rod 4, and a limiting component that limits the threaded tube 5 when it moves; the limiting component includes: a limiting tube 6 fixedly installed on the installation box 2, a limiting groove opened in the limiting tube 6, and a limiting bar 7 fixedly installed on the threaded tube 5; the limiting bar 7 slides in the limiting groove; the threaded tube 5 is fixedly connected to the cover plate 8.

[0029] When in use, start the first motor 3 to drive the threaded rod 4 to rotate, the threaded rod 4 drives the threaded tube 5 to move, and the threaded tube 5 drives the limiting strip 7 to slide in the limiting groove on the limiting tube 6. Through the mutual cooperation of the limiting strip 7 and the limiting groove, the threaded tube 5 can be limited, so that the threaded tube 5 moves upward along the axial direction of the threaded rod 4, and the threaded tube 5 drives the cover plate 8 to move upward, so that the cover plate 8 is separated from the foaming barrel 9, and then the stirring mechanism can be driven to move the foaming barrel 9 upward. At this time, natural latex and foaming agent can be added to the foaming barrel 9, and then the first motor 3 is started to rotate in the opposite direction, so that the cover plate 8 moves downward to seal the top of the foaming barrel 9, and the stirring mechanism is located inside the foaming barrel 9. At this time, the stirring mechanism is started to stir the natural latex and the foaming agent.

[0030] The stirring mechanism is driven to move up and down by the lifting mechanism. On the one hand, it is convenient to add natural latex and foaming agent to the foaming barrel 9, thereby achieving the purpose of convenient loading. On the other hand, the stirring mechanism can be separated from the foaming barrel 9, thereby facilitating the cleaning of the stirring mechanism and the foaming barrel 9 and preparing for subsequent use.

[0031] The stirring mechanism includes: a scraper 16, a driving component for driving the scraper 16 to rotate, and an adjusting component for adjusting the stirring range of the scraper 16; the driving component includes: a movable tube 11 rotatably mounted on the cover plate 8, and a second motor 10 that drives the movable tube 11 to rotate; the adjusting component includes: a connecting rod 13 movably mounted in the movable tube 11, an electric telescopic rod 17 fixedly mounted between the movable tube 11 and the connecting rod 13, a fixed plate 12 fixedly mounted on the movable tube 11, a connecting plate 14 fixedly mounted on the bottom end of the connecting rod 13, and a movable rod 15 hingedly mounted on the fixed plate 12 and the connecting plate 14 respectively; the adjacent ends of the adjacent movable rods 15 are hingedly connected to the scraper 16; the connecting rod 13 is arranged in a rectangular parallelepiped, and the inner cavity of the movable tube 11 matches the connecting rod 13.

[0032] After adding natural latex and foaming agent into the foaming barrel 9, the second motor 10 is started to drive the movable tube 11 to rotate, the movable tube 11 drives the fixed plate 12 and the connecting rod 13 to rotate, the connecting rod 13 drives the connecting plate 14 to rotate, and the adjacent movable rod 15 is driven to rotate through the fixed plate 12 and the connecting plate 14, and the scraper 16 is driven to rotate through the movable rod 15. Through the rotation of the movable rod 15 and the scraper 16, the natural latex and the foaming agent can be stirred, so that the natural latex and the foaming agent are evenly mixed, thereby improving the foaming effect.

[0033] At the same time, by starting the extension and retraction of the electric telescopic rod 17, the connecting rod 13 can be driven to move up and down, and the connecting rod 13 drives the connecting plate 14 to move up and down. The connecting plate 14 drives the adjacent movable rod 15 to move, thereby driving the scraper 16 to expand outward or contract inward, thereby expanding the stirring range of the scraper 16, further mixing the natural latex and the foaming agent evenly, and improving the foaming effect.

[0034] When the scraper 16 abuts against the inner wall of the foaming barrel 9, the material attached to the inner wall of the foaming barrel 9 can be scraped off. On the one hand, the natural latex will not adhere to the inner wall of the foaming barrel 9, so that it can be fully mixed with the foaming agent to improve the quality of the finished product; on the other hand, the residual material in the foaming barrel 9 can be reduced during discharge, which is beneficial to subsequent cleaning.

[0035] A glue feeder 18 is fixedly mounted on the top of the base 1, and the glue feeder 18 is communicated with the foaming barrel 9. By starting the glue feeder 18, the foamed material can be output, thereby facilitating discharging.

[0036] After that, start the second motor 10 and drive the movable tube 11 to rotate, and the movable tube 11 drives the fixed plate 12 and the connecting rod 13 to rotate, and the connecting rod 13 drives the connecting plate 14 to rotate, and the adjacent movable rod 15 is driven to rotate through the fixed plate 12 and the connecting rod 14. The movable rod 15 drives the scraper 16 to rotate. The rotation of the movable rod 15 and the scraper 16 can stir the natural latex and the foaming agent, so that the natural latex and the foaming agent are evenly mixed, thereby improving the foaming effect; at the same time, by starting the extension and contraction of the electric telescopic rod 17, the connecting rod 13 can be driven to move up and down, and the connecting rod 13 drives the connecting plate 14 to move up and down. The connecting plate 14 drives the adjacent movable rod 15 to move, thereby driving the scraper 16 to expand outward or contract inward, thereby expanding the stirring range of the scraper 16, further mixing the natural latex and the foaming agent evenly, thereby improving the foaming effect; when the scraper 16 abuts against the inner wall of the foaming barrel 9, the material attached to the inner wall of the foaming barrel 9 can be scraped clean. On the one hand, the natural latex will not adhere to the inner wall of the foaming barrel 9, so that it can be fully mixed with the foaming agent, thereby improving the quality of the finished product; on the other hand, the residual material in the foaming barrel 9 can be reduced during discharging, which is beneficial to subsequent cleaning.
