Description

Technical Field

[0001] The utility model relates to the field of sponge manufacturing, in particular to a sponge foaming machine. Background Technique

[0002] In modern industrial production, as a widely used material, the production technology of sponge is constantly developing and innovating. The quality and performance of sponge largely depend on the control and optimization of the foaming process. There are some problems in the actual application of traditional sponge foaming machines. For example, the stirring direction is single, which easily leads to uneven stirring of raw materials and affects the foaming effect and quality of the sponge. In addition, in terms of feeding, it is difficult for the previous feeding components to achieve accurate quantitative feeding, which easily leads to unreasonable raw material ratio.

[0003] After retrieval, Chinese Patent Publication No.: CN220973108U discloses a memory sponge high-pressure foaming machine, including a bottom plate. Above the bottom plate is provided a foaming machine body. A drain pipe is connected and fixed to the bottom end of the foaming machine body. A support ring is fixed to the bottom end of the foaming machine body. A rotating hole is opened at the top end of the foaming machine body. A driving motor is fixed to the top end of the foaming machine body. The output shaft of the driving motor penetrates through the rotating hole. Two fixing holes are opened at the top end of the foaming machine body. A high-pressure nozzle is fixed inside the fixing holes. Two scraping plates are rotatably arranged inside the foaming machine body. One end of two springs is fixed to one side of the scraping plate. A plurality of stirring rods are fixed to the outer wall surface of the rotating column. In the present utility model, the rotating column still rotates driven by the driving motor, so that the scraping plate scrapes the inner wall of the foaming machine body to prevent the attachment of impurities, thereby not affecting the reuse.

[0038] Referring to Figure 1 - Figure 3 , a valve one is arranged in the middle section of the discharge pipe 4. The valve one can control the opening and closing of the discharge pipe 4. A valve two is arranged in the middle section of the drain pipe 5. The valve two can control the opening and closing of the drain pipe 5. The upper surface of the fixed box 32 is fixedly connected to the inner wall of the top end of the foaming machine body 1. The rotating shaft 33 penetrates and is rotatably connected to the upper surface of the foaming machine body 1. The left surface of the U-shaped plate 34 contacts the inner wall on the left side of the foaming machine body 1. When the U-shaped plate 34 rotates, it can scrape off the raw materials adhered to the inner wall of the foaming machine body 1. The sleeve 36 is rotatably connected to the outer wall of the rotating shaft 33, and the two are closely fitted. The sponge foaming raw materials and water cannot enter the gap between the two. The sleeve 36 penetrates and is rotatably connected to the lower surface of the fixed box 32. The sleeve 36 and the fixed box 32 are in contact to maintain sealing. The bevel gear one 38 and the bevel gear two 39 are meshed. The bevel gear two 39 and the bevel gear three 311 are meshed. The rotating shaft 33 penetrates the upper surface of the bevel gear three 311.

The bevel gear three 311 can further drive the sleeve 36 and the stirring paddle 37 to rotate in the opposite direction, realizing the reverse stirring of the foaming raw materials.

[0039] Refer to Figure 1 、 Figure 4 The support plate 61 is fixedly connected to the top of the right surface of the foaming machine body 1, and the foaming machine body 1 provides support for the support plate 61. The L-shaped rod 64 penetrates and is slidably connected to the upper surface of the barrel 62. The right end of the L-shaped rod 64 is fixedly connected to the left surface of the slider 66. The L-shaped rod 64 and the slider 66 will move longitudinally synchronously. The second motor 68 is arranged on the upper surface of the slide plate 65. The threaded rod 67 penetrates and is rotatably connected to the upper surface of the slide plate 65. The threaded rod 67 penetrates and is threadedly connected to the upper surface of the slider 66. When the threaded rod 67 rotates, it can drive the slider 66 to move longitudinally. The bottom end of the compression spring 69 is fixedly connected to the upper surface of the support plate 611. When the slide plate 65 moves downward, it will squeeze the compression spring 69 to generate a reaction force. The left end of the connecting pipe 614 penetrates and is fixedly connected to the right surface of the foaming machine body 1. The connecting pipe 614 penetrates and is fixedly connected to the upper surface of the support plate 61. The support plate 611 is located above the feed pipe 612.

[0040] Working principle: When this device is in use, first move the L-shaped rod 64 downward. The downward moving L-shaped rod 64 will drive the threaded rod 67, the second motor 68, and the slide plate 65 to move downward. The downward moving slide plate 65 will squeeze the compression spring 69 to generate a reaction force, and the downward moving L-shaped rod 64 will drive the gasket 63 to move downward to generate a thrust. The thrust of the gasket 63 can push the raw material in the barrel 62 below the gasket 63. The raw material will flow through the connecting pipe 614 and enter the foaming machine body 1. By pressing the L-shaped rods 64 on different barrels 62, quantitative feeding can be achieved. After the feeding is completed, release the L-shaped rod 64. The reaction force of the compression spring 69 will push the slide plate 65, the slider 66, the threaded rod 67, the second motor 68, the L-shaped rod 64, and the gasket 63 upward. The upward moving gasket 63 will suck the raw material in the feed tank. The raw material will flow through the feed pipe 612 and enter the barrel 62. Since the downward pressure is basically the same as the elastic force of the compressed compression spring 69, the discharged material and the inhaled material can be kept roughly the same. When it is necessary to change the feeding value, start the second motor 68 to drive the threaded rod 67 to rotate, further driving the slider 66, the L-shaped rod 64, and the gasket 63 to move longitudinally, so as to change the initial position of the gasket 63.

[0041] After the blanking is completed, start the first motor 31 to drive the rotating shaft 33 to rotate. The rotating rotating shaft 33 will drive the U-shaped plate 34, the stirring blade 35 and the first bevel gear 38 to rotate. The rotating stirring blade 35 can stir the raw materials in the positive direction, and the rotating U-shaped plate 34 can scrape off the raw materials adhering to the inner wall of the foam generator body 1. The rotating first bevel gear 38 can drive the third bevel gear 311, the sleeve 36 and the stirring paddle 37 to rotate in the reverse direction under the transmission of the second bevel gear 39. The reversely rotating stirring paddle 37 can stir the raw materials in the reverse direction, so as to achieve the effect of double-sided stirring, making the raw materials stirred more evenly. After the raw materials are stirred, turn off the first motor 31 and open the first valve, so that the raw materials after stirring and foaming enter the molding barrel for molding.

[0042] Then close the first valve and start the high-pressure nozzle 2 to spray water into the foam generator body 1, and start the first motor 31 to stir the water inside. The water can clean the inner wall of the foam generator body 1. After the cleaning is completed, turn off the first motor 31 and the high-pressure nozzle 2 and open the second valve to drain the sewage from the drain pipe 5.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
