Description
Technical Field
The utility model relates to a product production facility is moulded to commentaries on classics hub type paper indicates especially that a space configuration who utilizes whole equipment becomes to each other for moving about freely and quickly alternative reciprocating cycle fashioned manufacturing procedure that continues, can reduce occupation space and promote productivity ratio's paper by a wide margin and mould product commentaries on classics hub type production facility in the configuration by a wide margin.
Background
According to the prior art, a product manufactured by mixing and beating a pulp fiber material or a material containing plant fibers into a pulp material, absorbing pulp by a pulp absorbing mold, attaching the pulp, and performing hot press molding is distinguished from a plastic product, which is generally called a paper-plastic product, or also called a molded product or a pulp molded product, and is called a paper-plastic product in the specification. The paper-plastic product has the advantage of easy recovery, remanufacture and reuse, accords with the trend of environmental protection, reuse, energy saving and carbon reduction, is rapidly accepted and is willing to be adopted by the industry and the general public, and the paper-plastic product is often visible, such as: products such as bowls, plates, cup covers, packaging materials, shock absorbing materials, cushion materials and the like are gradually adopted, and even various products are manufactured in the form of paper-plastic products. The manufacturing process and the technological skills of paper and plastic products have been improved and changed frequently in recent years, but the use of fiber material as the starting material is the basic principle.
The process for manufacturing paper and plastic products is roughly divided into three operations of 'slurry suction molding', 'drying and dehumidifying' and 'hot press molding', wherein the 'slurry suction molding' is simply that a slurry suction mold descends and immerses into a slurry box filled with slurry, then a suction device sucks the slurry in the slurry box through the slurry suction mold in a vacuum manner to form a 'blank layer' on the mold surface of the slurry suction mold, when the slurry suction mold sucks the blank layer to ascend away from the slurry box, the blank layer is gradually dehumidified due to continuous suction, then the slurry suction mold and the blank layer are moved to and a cold press mold to press the blank layer, so that the slurry layer is dehumidified and molded into a blank at the same time, and then the blank layer is removed to finish the 'slurry suction molding'. Because the primary blank is still in a relatively high humidity state, the removed primary blank is sent to a drying area for drying operation, generally adopting a hot air drying mode to rapidly dehumidify the primary blank, and when the moisture content is reduced to a relatively low humidity state, the primary blank is removed from the drying area to complete the drying and dehumidifying operation. The primary blank moved out of the drying zone is immediately sent into a hot-pressing and shaping mechanism to carry out hot-pressing and shaping operation on the primary blank in a relatively low-humidity state, so that the primary blank is completely dried and shaped into a finished product of the paper-plastic product. Of course, the finished product of the paper-plastic product produced by the hot press molding operation must be subjected to operations of trimming (removing flash), checking (checking whether the quality is qualified) and packaging (to facilitate product discharge), but these subsequent operations are not repeated.
The production process of paper-plastic product is characterized by that it mainly uses several pulp-sucking moulds to form a rotatable rotary hub forming machine, and uses power to drive said rotary hub forming machine to make circumferential rotation so as to make several pulp-sucking moulds implement pulp-sucking operation and extrusion operation at different time to obtain primary blank product, then the primary blank product is transferred out and undergone the processes of drying and moisture-reducing and hot-press forming, so that the paper-plastic product can be continuously made up by means of the continuous intermittent rotation of rotary hub forming machine.
In the conventional production line, such as the production process and equipment of the rotary hub type paper-plastic product shown in fig. 1, a rotary hub forming machine 10 continuously performs a "slurry sucking and molding" operation to continuously complete a primary blank, and then the primary blank is moved into a hot air dryer 11 by manpower standing in front of the rotary hub forming machine 10 to perform drying and dehumidifying operations, because the primary blank is dried and dehumidified by hot air, a corresponding time is required for the process, and the secondary blank continuously enters, so that the primary blank is slowly moved inside the hot air dryer 11 by adopting a conveyor conveying manner, a long strip-shaped large space is also required for installing the hot air dryer 11, and the production using the rotary hub forming machine 1 must be matched with the hot air dryer 11 at present; the primary blank after drying and dehumidifying is moved to a diversion conveyor 12 by manpower standing at the outlet end of the hot air dryer 11, and because the subsequent operation needs diversion treatment, the primary blank after passing out of the hot air dryer 11 is respectively moved into two curved diversion conveyors 12, so as to facilitate the subsequent treatment in different flow lines; after the flow is divided by the flow dividing conveyor 12, the primary blank is immediately moved to an abnormal finishing conveyor 13 for abnormal finishing, so that the primary blank meets the standard; then the primary blank enters a region of a hot-press shaping mechanism 14, and the primary blank is subjected to hot-press shaping operation to form a finished product of the paper-plastic product; finally, the finished products of the paper-plastic products are moved to a stacking machine 15, stacked in proper quantity and then transferred to a product packaging area for packaging the paper-plastic products.
The utility model discloses the research and development and the manufacturing work of making equipment, manufacturing process and the finished product development of product are moulded to the people specialty, through the experience of the various equipment of long-time contact mould paper product, think above-mentioned revolving hub type paper of knowing about and mould product production process and equipment in the use, actually have following disappearance: firstly, the conventional hub-type paper-plastic product production process needs to be matched with the hot air dryer 2 to reduce the water content, the whole occupied space of the combined product is large, especially the hot air dryer 2 occupies a long and large strip-shaped space, so that the rest of the space of a factory building is difficult to recycle after the conventional hub-type production equipment is arranged in the factory building space, and the utilization rate of the factory building space is low; moreover, if the hot air dryer 11 is used for drying the primary blank in the production process of the paper-plastic product, the time is too long, and even the pulp suction time needs to be reduced or the drying time of the primary blank needs to be prolonged, so that the production efficiency is greatly reduced and the manufacturing cost is increased; finally, the production process and equipment of the conventional hub-rotating type paper-plastic product have large manpower requirements, high energy consumption and low intelligent level, which all relatively increase the production cost.
