Description

Production process and equipment of hub-type paper-plastic products

The present invention is a manufacturing process and equipment for the production of a hub-type paper-plastic product, especially a process that utilizes the space of the overall equipment to be freely configured to form a continuous molding process, which can greatly reduce the space occupied by the configuration, improve product quality, and greatly increase productivity. Production process and equipment for hub-type paper-plastic products.

According to this, there have been developed products made of pulp fiber material and or including plant fiber material mixed beating as the pulp material, and the slurry is adhered to the slurry by the suction mold, and then the product is manufactured by the hot pressing technology. "Plastic products" are generally referred to as "paper-plastic products", or they are also referred to as "molded products" or "pulp-molded products". Today, they are all referred to as "paper-plastic products" in this manual. ". Paper-plastic products have the advantage of being easily recycled, remanufactured and reused. They are in line with the trend of environmentally friendly reuse and energy saving and carbon reduction. Therefore, they are quickly accepted and adopted by the industrial and commercial industry and the general public. Paper-plastic products are often seen such as: bowls, plates, Products such as cup lids, packaging materials, shock-absorbing materials, and cushion materials have gradually been adopted, and even various products have tried to be manufactured in the form of paper-plastic products. The manufacturing methods and techniques of paper-plastic products have been improved and changed frequently in recent years, but the basic principle is to use fiber materials as starting materials.

Regarding the dry pressing process of manufacturing paper-plastic products, the rough distinction must go through the three operations of "blister molding", "drying and dehumidification", and "hot pressing molding". In simple terms, "blister molding": A slurry suction mold is lowered and immersed into a headbox full of slurry, and then a suction device is used to vacuum suction the slurry in the headbox through the slurry suction mold, so that the mold surface of the slurry suction mold becomes a shape "Blank layer", when the suction mold absorbs the blank layer and rises away from the headbox, the blank layer is gradually dehumidified due to the continuous suction effect, and then the suction mold and the blank layer are shifted to one The cold press mold closes and squeezes the blank layer, so that the slurry layer is reduced in humidity and simultaneously shaped into a preliminary blank product, which is then removed to complete the "slurry suction molding" operation. Because the primary product is still in a relatively high humidity state at this time, the removed primary product is immediately sent to a drying area for drying. Generally, hot air drying is used to quickly dehumidify the primary product. When the moisture content drops to a relatively low humidity state, move out of the drying area to complete the "drying and dehumidification" operation. The first embryos removed from the drying area are then sent to a "hot-pressing setting mechanism" to perform hot-pressing and setting operations on the first embryos in a relatively low-humidity state, so that they are completely dried and shaped into finished paper-plastic products. Of course, the finished paper-plastic products produced by the hot-pressing and shaping operations still need to go through the operations of trimming (remove flash), inspection (check whether the quality is qualified), and packaging (for the sake of production), but these follow-up operations do not need to be added. Go into details.

There are many production processes for paper and plastic products, one of which is a hub-type production process that has gradually attracted attention. It is mainly composed of multiple suction mold positions to form a rotatable hub forming machine, which is driven by power Make a circular rotation to make multiple suction dies perform suction and squeeze operations in time to make them into primary embryos, and then transfer the primary embryos for subsequent "drying and dehumidification" and "hot pressing" In this way, the continuous intermittent rotation of the indexing time-sharing of the rotary hub molding machine can allow the paper-plastic product manufacturing process to continue.

The conventional traditional production line shown in Figure 1 shows the production process and equipment of a rotary hub paper-plastic product. A rotary hub forming machine 10 continuously performs the "suction molding" operation to continuously complete the preliminary product, and then stands on the rotary hub. The manpower in front of the hub forming machine 10 moves the preforms into a hot air dryer 11 for drying and dehumidification operations, because the process of drying and dehumidifying the preforms with hot air requires a corresponding time. In addition, the initial products at the rear continue to enter, so the conveyor transportation method allows the initial products to move slowly inside the hot air dryer 11. Therefore, a large strip of space is required to install the hot air dryer 11. At present, the production of the rotary hub molding machine 1 must be matched with the hot air dryer 11; the first embryo after the drying and dehumidification operation is completed, and then the manpower standing at the outlet of the hot air dryer 11 is moved to a split conveyor 12. Because the follow-up operations need to be split, the primary embryo lines after the hot air dryer 11 are passed are moved to the two-curved split conveyor 12 to facilitate subsequent processing in different streamlines; After the diverting conveyor 12 is diverted, the preliminary product is then moved to an abnormal finishing conveyor 13 for abnormal finishing, so that the preliminary product meets the specifications; then the preliminary product enters the area of a hot-press setting mechanism 14 to remove the preliminary product. The embryonic product becomes the finished paper-plastic product through the hot pressing and shaping operation; finally, the finished paper-plastic product is moved to a stacking machine 15, after an appropriate number of stacking, and then transferred to a product packaging area for paper-plastic product packaging.

The inventor specializes in the research and development and manufacturing of various paper-plastic products manufacturing equipment, manufacturing processes, and finished product development. Through long-term experience in contact with various equipment of molded paper products, he has realized that the above-mentioned conventional rotary hub-type paper-plastic products production process and In the use of the equipment, there are actually the following shortcomings: First of all, the production process of conventional rotary-hub paper-plastic products must be equipped with a hot-air dryer 2 to reduce the moisture content, and the whole composition takes up a large space, especially the hot-air dryer 2 It occupies a large strip of space. Therefore, when the conventional hub-type production equipment is installed in the factory space, the remaining space is difficult to reuse, resulting in the lack of low utilization rate of the factory space. Furthermore, if hot air is used in the production process of paper-plastic products The dryer 11 is used to dry the preliminary product, and its time is too long, and it is even necessary to slow down the suction time or extend the drying time of the preliminary product, which greatly reduces the production efficiency and increases the manufacturing cost; the traditional rotary hub machine is a dry pressing process, and Most of the products produced are paper-plastic products with rough or no smooth quality, which are limited in production projects. Finally, the production process and equipment of conventional rotary-hub paper-plastic products require large manpower, high energy consumption, and low level of intelligence. All of these are relatively high production and manufacturing costs.

In view of the above shortcomings, the present inventors intensively studied and improved ideas, hoping to provide a new-thinking production process and equipment for the hub-shaped paper-plastic products to solve the above shortcomings.
