Description

technical field [0001] The invention relates to the technical field of pillow core production, in particular to a multifunctional shaping production line capable of producing high, medium and low density pillow cores. Background technique [0002] Usually, fiber materials are loosely filled into products. For example, when making pillows, cushions and other household items, fiber materials are loosely filled into pillow inner covers and cushion inner covers. The way is easy to make the softness and hardness of the product vary, and it is easy to move and deform, which in turn affects the comfort and durability of the product. Although the domestic invention patent with the patent number of 200910132363.X discloses "a production method, production equipment and production line for a shaped pillow core", it includes a number of shaped molds, which are used to load the prepared pillow core raw materials and preliminarily shape them.

Problems solved by technology

[0002] Usually, fiber materials are loosely filled into products. For example, when making pillows, cushions and other household items, fiber materials are loosely filled into pillow inner covers and cushion inner covers. The method is easy to make the softness and hardness of the product vary, and it is easy to move and deform, which will affect the comfort and durability of the product

Although the domestic invention patent with the patent number of 200910132363.X discloses "a production method, production equipment and production line for a shaped pillow core", it includes a number of shaped molds, which are used to load the prepared pillow core raw materials and preliminarily shape them. The inner cavity contour of the mold is the same as the outer contour shape of the pillow core; it also includes a thermal energy setting machine, which heats and shapes the pillow core raw materials. Specifically, the thermal energy setting mechanism is an oven, which is heated by high voltage. The temperature in the oven is uniform, and a cooling fan is installed at the outlet of the oven; however, the above-mentioned production equipment has the following defects: the hot-melt forming temperature of the blended fiber cotton used as the pillow core raw material is in the range of 130°C to 170°C, when it is installed in a sealed When the setting mold is placed in an oven for heating and setting, since the oven uses high-voltage heating to directly heat the air in the furnace, the heat generated will heat the blended fiber cotton inside through the setting mold to make it heat-set, but the induction The heat energy first makes the surface layer of the pillow material contacting the mold heated and shaped. Since the pillow material is a thermally poor conductor, at this time, it is difficult for the external heat to sense the inner layer of the pillow material, especially the middle of the pillow core. The blended fiber cotton loose material in most areas cannot reach the hot-melt temperature and cannot be heat-set, that is, the pillow core that has been heat-set in this oven is a blended fiber cotton that has been heat-set on the surface but is still not heat-set inside. Loose material, the elasticity, comfort and product quality of the finished pillow core have not been substantially improved

In this regard, the domestic invention patent with the patent number of 201010542539.1 discloses a pillow core heat-setting device for the purpose of solving the above problems, but in actual production, the pillow core heat-setting device has design deficiencies, specifically mold placement On the roller conveying line, the contact area between the mold and the roller conveying line is small, and the hot air in the heating furnace tends to flow away from the gap between the two rollers, failing to fully penetrate the mold. Multiple parallel and vertical movable insulating doors on the side of the furnace enter or leave the heating furnace, resulting in poor airtightness, high energy consumption, and low production capacity of the heating furnace; meanwhile, coupled with the irregular rotation of the roller conveyor line, the When the mold is running against the movable insulation door on the side of the heating furnace, it is easy to move out of position, and then it is easy to cause mold blockage

Therefore, it is also difficult for this pillow heat-setting device to produce a finished pillow that has been completely heat-melted inside and outside, that is, the elasticity, comfort and product quality of the finished pillow have not yet reached the expected beneficial effect, and the production time The pillow core heat setting device also has bad phenomena such as mold blockage, which still needs further improvement and development
