Embodiment Construction
[0021] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments of the description:
[0022] Such as figure 1 Shown: a density board initial molding device, which includes a frame 1, a number of transmission rollers 2 arranged on the frame 1, a slurry suction blanket 3 wound on the transmission roller 2 and driven by the transmission roller 2, Cooperate with several pulp suction mechanisms for absorbing pulp fibers on the pulp suction blanket 3, forming and thickness-setting mechanisms for absorbing pulp fiber on the pulp suction blanket 3, and several water absorption mechanisms for absorbing moisture on the pulp suction blanket 3.
[0023] At least two pulp suction mechanisms can be set. After the pulp suction blanket 3 passes through the first pulp suction mechanism, the thickness of the pulp fibers on the pulp suction blanket 3 is not enough or the pulp fibers are not uniform enough. After the slu...

The invention relates to a density board pre-profiling device. The density board pre-profiling device comprises a rack, multiple conveying rollers arranged on the rack, a pulp adsorbing blanket wound around the conveying rollers and driven by the conveying rollers to be conveyed, multiple pulp adsorbing mechanisms matched with the pulp adsorbing blanket to adsorb pulp fibers, a profiling and thickness defining mechanism for adsorbing the pulp fibers on the pulp adsorbing blanket, and multiple water absorption mechanisms for adsorbing water on the pulp adsorbing blanket. The device has the advantages that the structure is simple, and the production efficiency is high; the pulp adsorbing mechanisms are simple in structure, high in adsorption efficiency and capable of being applied to large density board industrial production; the water absorbing mechanisms absorb the water evenly and can rapidly absorb the redundant water on the pulp adsorbing blanket, the pulp adsorbing blank can be coated with the pulp fibers on the surfaces of pulp adsorbing rollers in an adhesion mode, and collecting rollers can adsorb the pulp fibers on the pulp adsorbing blanket; the profiling and thickness defining mechanism can accurately control the thickness of density boards, and it is guaranteed that the quality of the density boards is uniform.
Description
technical field [0001] The invention relates to a density board primary forming device. Background technique [0002] MDF has become the new darling of decorative materials because of its durability and aesthetics, and the market demand for it is increasing. However, most of the density boards currently used are produced from wood fibers, which are restricted by the lack of forest resources in our country. During the papermaking process, some papermaking wastewater rich in pulp fibers will be produced. The pulp fibers recovered from the papermaking wastewater can be used in the preparation of density boards to realize the secondary utilization of raw materials. To make density boards with pulp fibers, the pulp fibers must first be formed, and then the initially formed density boards should be squeezed and dried. Contents of the invention [0003] The object of the present invention is to provide a density board primary forming device with simple structure and high produc...
