Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmentally friendly flame-retardant ecological board production technology, specifically, to a multi-stage continuous adhesive mixing system for mixing powdered fiber materials. Background Technology
[0002] Environmentally friendly flame-retardant ecological boards are a new type of decorative board that combines environmental protection and flame-retardant functions, widely used in homes, commercial spaces, and public buildings. These boards are made from wood fibers or plant fibers (such as rice husks and straw) as the base material, pressed together with environmentally friendly resin adhesives, and covered with a decorative layer (such as melamine-impregnated paper). Flame retardants are added or flame-retardant processes are used to give them fire-resistant properties. Our company's environmentally friendly flame-retardant ecological board production line uses a cold-pressing process. Before installation, the powdered fiber material (wood flour), powdered adhesive raw materials, and liquid adhesive raw materials must be thoroughly mixed to meet the board's production process requirements.
[0003] Traditional adhesive mixing systems first thoroughly mix measured quantities of powdered adhesive raw material A, powdered adhesive raw material B, and other auxiliary materials with measured quantities of liquid adhesive raw material to create a finished adhesive with specific properties. This finished adhesive is then pumped into a mixer to be mixed with wood flour and other fibrous materials, with intermittent stirring. While traditional mixing systems achieve a certain degree of thorough mixing of wood flour and adhesive, they have significant drawbacks:
[0004] Firstly, its complex process and low mixing efficiency make it unsuitable for large-scale, continuous production, severely restricting the output of the production line.
[0005] Secondly, because the finished adhesive has the characteristic of easy solidification, the residual adhesive inside the conveying pipeline must be removed in a timely and thorough manner after the spraying action is completed. Otherwise, the residual adhesive will solidify in the conveying pipeline, causing blockage of the pump and adhesive supply pipeline. At the same time, the residual adhesive in the mixing tank will also solidify and harden. This not only increases the cost of manual cleaning, but also seriously restricts the stability of the equipment's adhesive preparation and supply system. More seriously, the detached adhesive blocks and particles are mixed with the adhesive material in the board blank, making it impossible to properly laminate the board blank in the later stage, affecting the qualification rate of the board.
[0006] Therefore, it is necessary to improve the traditional glue mixing system. Utility Model Content
[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-stage continuous adhesive mixing system. This invention features high mixing efficiency, continuous feeding and discharging, meeting the requirements of large-scale, continuous production. It also effectively solves the problems of easy clogging and difficult cleaning caused by the easy solidification of finished adhesives in traditional adhesive supply and mixing systems, greatly saving manual cleaning costs and improving the pass rate of boards.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a multi-stage continuous adhesive mixing system, including a primary mixer, a secondary mixer, a tertiary mixer, and a pumping system. The discharge port of the primary mixer and the inlet of the secondary mixer, as well as the discharge port of the secondary mixer and the inlet of the tertiary mixer, are connected by conveying pipes. The top of the secondary mixer is provided with an adhesive spraying mechanism for spraying adhesive into the secondary mixer. The pumping system provides liquid adhesive raw materials to the adhesive spraying mechanism.
[0009] Based on the above, the primary mixer is a twin-shaft mixer.
[0010] Based on the above, the secondary mixer is a ring-type adhesive mixer.
[0011] Based on the above, the three-stage mixer is a ring-type adhesive mixer.
[0012] Based on the above, the housings of the primary mixer, the secondary mixer, and the tertiary mixer are mainly composed of an upper cover and a lower cover connected by a hinge. An electric swing mechanism is provided between the upper cover and the lower cover, and the electric swing mechanism drives the upper cover to rotate around the hinge to open and close.
[0013] Based on the above, the primary mixer, the secondary mixer, and the tertiary mixer are arranged from top to bottom.
[0014] This invention represents a substantial improvement over existing technologies. Specifically, it involves first continuously feeding wood flour and powdered adhesive raw materials into a primary mixer for initial mixing. The pre-mixed material is then fed into a secondary mixer, where a pumping system and a spraying mechanism continuously spray liquid adhesive raw materials at a preset speed. This further mixes the materials and liquid adhesive raw materials in the secondary mixer. Finally, the mixture is fed into a tertiary mixer for thorough mixing, and then discharged after uniform mixing. Compared to traditional processes, this mixing system not only achieves thorough mixing of materials and adhesives in a short time with high efficiency, but also enables continuous feeding and discharging, meeting the requirements of large-scale, continuous production. This effectively increases production line output and yields significant economic benefits. Meanwhile, this adhesive mixing system simplifies the adhesive mixing process by combining adhesive preparation and mixing together, instead of preparing the adhesive first and then mixing it. This effectively solves the problems of easy clogging and difficult cleaning caused by the easy solidification of finished adhesive in traditional adhesive supply and mixing systems. It greatly saves on manual cleaning costs and avoids detached adhesive blocks and particles from being mixed with the adhesive material in the board blank, thereby improving the board's qualification rate.

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0018] like Figure 1 As shown, the multi-stage continuous adhesive mixing system includes a primary mixer 1, a secondary mixer 2, a tertiary mixer 3, and a pumping system 4 arranged from top to bottom. The primary mixer 1 is a twin-shaft mixer, and the secondary mixer 2 and the tertiary mixer 3 are both ring mixers. The discharge port of the primary mixer 1 and the inlet of the secondary mixer 2, as well as the discharge port of the secondary mixer 2 and the inlet of the tertiary mixer 3, are connected by conveying pipes 5. The top of the secondary mixer 2 is equipped with an adhesive spraying mechanism 6 for spraying adhesive into the secondary mixer 2, and the pumping system 4 provides liquid adhesive raw materials to the adhesive spraying mechanism 6.
[0019] The housings of the primary mixer 1, the secondary mixer 2, and the tertiary mixer 3 are mainly composed of an upper cover and a lower cover connected by a hinge. An electric swing mechanism is provided between the upper cover and the lower cover, which drives the upper cover to rotate around the hinge to open and close. The electric swing mechanism allows the upper cover to be easily opened, facilitating inspection and maintenance.
[0020] The working process of this multi-stage continuous mixing system is as follows:
[0021] (1) The raw materials (wood flour, powdered adhesive raw material A and powdered adhesive raw material B) of a set weight are uniformly and continuously added to the primary mixer 1 by a metering belt for preliminary mixing. The material after preliminary mixing enters the secondary mixer 2 through the conveying pipe 5.
[0022] (2) The secondary mixer 2 adopts frequency conversion control. When the material after preliminary mixing enters the secondary mixer 2, the pumping system 4 is turned on to provide liquid adhesive raw material to the spraying system. The spraying system continuously sprays liquid adhesive raw material onto the material at a preset spraying speed, so that the material and liquid adhesive raw material are further mixed in the secondary mixer 2 and then enter the tertiary mixer 3. Since the liquid adhesive raw material is a salt solution, it is not easy to solidify and block the pumping system 4 and the spraying mechanism 6, which can avoid the blockage and cleaning problems of the traditional glue supply system.
[0023] (3) After entering the three-stage mixer 3, the material and liquid adhesive raw materials are fully mixed under the action of the high-speed rotating stirring claws to achieve the purpose of uniform mixing;
[0024] (4) After the material is mixed, it is conveyed to the next process by a belt conveyor after it comes out of the discharge port of the three-stage mixer 3.
[0025] Compared to traditional processes, this adhesive mixing system not only enables materials and adhesives to achieve thorough mixing in a short time with high mixing efficiency, but also achieves continuous feeding and discharging, meeting the requirements of large-scale, continuous production and effectively increasing production line output, resulting in significant economic benefits. Furthermore, this system simplifies the adhesive mixing process by combining adhesive preparation and mixing, rather than preparing the adhesive first and then mixing it. This effectively solves the problems of easy clogging and difficult cleaning caused by the easy solidification of finished adhesives in traditional adhesive supply and mixing systems, greatly saving on manual cleaning costs and preventing detached adhesive lumps and particles from mixing with the slab blanks, thus improving the pass rate of the slabs.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
