Description

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

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

According to the press, at present, there have been developed products made of pulp fiber material and or including plant fiber material mixed and beating as pulp material, and the pulp is adhered to the pulp by suction mold, and then produced by hot pressing and setting technology. Generally speaking, it is called "paper-plastic products", or it is also called "molded products" or "pulp-molded products", which are now referred to as "paper-plastic products" in this manual. ". Paper-plastic products have the advantage of being easy to recycle, re-manufacture and reuse, which is in line with the trend of environmental protection, recycling and energy saving and carbon reduction. Therefore, they are quickly accepted and used by the business community and the general public. Paper-plastic products are often seen such as: bowls, plates, Cup lids, packaging materials, shock-absorbing materials, cushion materials and other products are gradually being used, and even various products have been tried to be manufactured in the form of paper-plastic products. The manufacturing methods and process skills of paper-plastic products have been improved and changed frequently in recent years, but the use of fiber materials as the starting material is the basic principle.

Regarding the dry pressing process of manufacturing paper-plastic products, it can be roughly divided into three operations: "suction molding", "drying and dehumidification" and "hot pressing". Among them, "suction molding" is simply, It is lowered and immersed into a pulp box filled with pulp by a suction mold, and then a suction device is used to vacuum the slurry in the pulp box through the suction mold, so that the mold surface of the suction mold is formed into a "Blank layer", when the suction mold absorbs the blank layer and rises out of the pulp box, the blank layer is gradually dehumidified due to continuous suction, and then the suction mold and the blank layer are displaced together with a The cold pressing die closes the mold to extrude the blank layer, so that the slurry layer reduces the humidity and is simultaneously molded into a preliminary embryo product, which is then removed to complete the "suction molding" operation. Because the initial embryos are still in a relatively medium-high humidity state at this time, the initial embryos are immediately sent to a drying area for drying. When the moisture content drops to a relatively low humidity state, it will be removed from the drying area to complete the "drying and dehumidifying" operation. The initial embryos removed from the drying area are immediately sent into a "hot-pressing setting mechanism" to perform hot-pressing and setting operations on the relatively low-humidity initial embryos, so that they are completely dried and shaped into finished paper-plastic products. Of course, the finished product of the paper-plastic product produced by the hot-pressing setting operation still needs to go through the operations of trimming (removing the flash), inspection (checking whether the quality is qualified) and packaging (to facilitate the production), but these follow-up operations do not need to be added. Repeat.

There are many production processes for paper-plastic products, one of which is the hub-type production process, which 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 extrusion operations at different times, so as to become a preliminary embryo, and then transfer the preliminary embryo for subsequent "drying and dehumidification" and "hot pressing". In this way, through the continuous and intermittent rotation of the rotary hub forming machine indexing and dividing the time, the paper-plastic product manufacturing process can be continued.

The conventional production line as shown in Figure 1 shows the production process and equipment of rotary hub-type paper-plastic products. A rotary hub forming machine 10 continuously performs the "suction molding" operation to continuously complete the initial embryo. The manpower in front of the hub forming machine 10 moves the initial embryos into a hot air dryer 11 for drying and dehumidification operations, because the operation of drying and dehumidifying the initial embryos with hot air requires corresponding time. And the initial embryos continue to enter at the rear, so the conveyor is used to transport the initial embryos in the hot air dryer 11 at a slow speed, and therefore a long and large space is required to set the hot air dryer 11, and At present, the production using the rotary hub forming machine 1 must be matched with the hot air dryer 11; after the drying and dehumidification operation is completed, the initial embryo is then moved to a split conveyor by the manpower standing at the outlet end of the hot air dryer 11. 12. Because of the need for shunt processing for subsequent operations, the first embryo strains after passing through the hot air dryer 11 are respectively moved into two curved arc-shaped shunt conveyors 12 to facilitate subsequent processing in different streamlines; After the diversion conveyor 12 divides the flow, the preliminary embryos are immediately moved to an abnormal sorting conveyor 13 for abnormal sorting, so that the preliminary embryos meet the specifications; The embryonic product is formed into a finished paper-plastic product through a hot-pressing setting operation; finally, the finished paper-plastic product is moved to a stacking machine 15, and after stacking an appropriate number, it is transferred to a product packaging area for packaging of the paper-plastic product.

The inventor of the present invention is specialized in the research and development and manufacturing of manufacturing equipment, manufacturing process and finished product development of various paper-plastic products. Through the experience of contacting various equipments for moulded paper products for a long time, the inventor realizes that the above-mentioned conventional hub-type paper-plastic product production process and In the use of the equipment, there are actually the following deficiencies: First of all, the conventional production process of hub-type paper-plastic products must be equipped with a hot air dryer 2 to reduce the moisture content, which occupies a large space as a whole, especially the hot air dryer 2 It takes up a lot of space in the shape of a strip. Therefore, after the conventional hub-type production equipment is installed in the factory space, it is difficult to reuse the remaining space, resulting in the lack of low utilization rate of factory space; The dryer 11 is used to dry the initial embryos, and the time is too long, and it is even necessary to slow down the suction time or prolong the drying time of the initial embryos, which greatly reduces the production efficiency and increases the manufacturing cost; the traditional rotary hub machine is a dry pressing process, which Most of the products produced are paper-plastic products that are relatively rough or do not require smooth quality, which are limited in production projects; finally, the production process and equipment of conventional hub-type paper-plastic products require large manpower, high energy consumption, and low level of intelligence. All of these relatively increase the manufacturing cost.

In view of the above deficiencies, the inventor of the present invention has deeply conceived, researched and improved, and hopes to provide a new thinking in the production process and equipment of a hub-type paper-plastic product to solve the above deficiencies.
