Description

technical field [0001] The present invention relates to a foam board machine, in particular to a foam board machine with two air intakes, which is mainly used to manufacture foam boards. Steam is fed into both ends, which is conducive to a more uniform distribution of steam, which belongs to a kind of equipment for manufacturing foam boards. Background technique [0002] With the wide application of foam boards and the increasing usage, people have higher and higher requirements for the quality of foam boards, which makes foam board manufacturers put forward higher requirements for the equipment for manufacturing foam boards. At present, foam boards are mainly manufactured by foam board machines, which requires greatly improving the performance requirements of the foam board machines, so that reliable and high-quality foam boards can be produced. [0003] Existing foam board machines usually include a mold cavity for placing raw materials and a set of pipelines for supplyin...

Problems solved by technology

The structural design of this type of foam sheet machine is not reasonable enough, the overall layout is not scientific enough, and the steam is difficult to be evenly distributed into the mold cavity, resulting in uneven heating of the raw materials by steam, especially when the overall length of the foam sheet machine is long, such as foam When the length of the board machine is more than 6m, it is difficult to evenly distribute the steam into the mold cavity by means of air intake at one end, which not only affects the working efficiency of the foam board machine, but also greatly reduces the quality of the manufactured foam board, and makes Steam is difficult to be used effectively, resulting in waste of energy, which is not conducive to energy saving and environmental protection

[0004] For example, the publication date is June 11, 2008, and the publication number is CN201070824 in the Chinese patent, which discloses a foam sheet molding machine, which consists of a frame, an air box, a door, a feed air gun, a door opening cylinder, The ejector oil cylinder, locking oil cylinder, steam inlet pipe, cooling pipe and universal top plate are composed. The two inner large surfaces of the air box are arc-shaped. With this structure, the number of particles in the center of the air box can be increased in advance, so that the surrounding of the plate The density is consistent with the center density, and the produced foam slabs will not have the phenomenon of central depression; however, the foam slabs produced by the foam slab forming machine have an arc-shaped structure, which requires cutting corners, resulting in waste of materials, and , the foam sheet molding machine has a structure with air intake at one end, and the structural design is not reasonable enough, so that the steam distribution in the foam sheet molding machine is not uniform enough. The steam at the end of the steam inlet is strong, and the steam at the end far away from the steam inlet is weak, which greatly Affects production efficiency and reduces the quality of foam boards

Another example is that the publication date is April 02, 2008, and the publication number is CN201042836 in the Chinese patent, which discloses a kind of EPS sheet forming machine. With the ventilation holes set on the cavity plate of the mold cavity, the movable bottom mold with ventilation holes, and the steam inlet and exhaust ports of each steam chamber, a partition is set in the four vertical steam chambers of the mold cavity, and the partition board A communication pipe with a valve is set between the main and auxiliary steam chambers formed on both sides of the main and auxiliary steam chambers; a vent hole is provided within a certain distance above the cavity plate of the auxiliary steam chamber; the EPS sheet forming machine is also a structure of air intake at one end, so that Uneven distribution of steam inside the mold cavity reduces the quality of the EPS sheet

In addition, the publication date is June 29, 2005, and the publication number is CN2706296. In the Chinese patent, a multi-chamber foam sheet molding machine is disclosed. The multi-chamber foam sheet molding machine includes an upper air chamber, a lower air chamber, The first rear air chamber, the first front air chamber; it also includes N rear air chambers, N front air chambers, and N grilles; the grilles divide the mold cavity into different heights to realize the production of different specifications on the same equipment products; where N is a positive integer; the multi-chamber foam sheet molding machine also has a structure of air intake at one end, which makes the steam distribution in the mold cavity not uniform enough and reduces the quality of the product

[0005] To sum up, the structure design of the existing foam sheet molding machines is not reasonable enough, the layout is not scientific enough, the steam utilization rate is low, and it is difficult to meet the requirements of energy saving and environmental protection; Low, the steam is difficult to evenly distribute into the mold cavity of the foam board forming machine, and the quality of the manufactured foam board is poor, which hinders the better development of the foam board industry
