Description

Technical Field

[0001] The invention relates to the field of bamboo and wood processing equipment, in particular to a bamboo board rapid forming cold pressing device. Background Art

[0002] Plywood is one of the commonly used materials for furniture, and can also be used as material for airplanes, ships, trains, cars, buildings and packaging boxes. Plywood can improve the utilization rate of wood and is a major way to save wood.

[0003] At present, the forming of plywood is usually carried out by cold pressing. The cold press presses the glue-coated boards for 1-2 days until the glue is air-dried, which has low production efficiency. In addition, in the actual air-drying process, the solvent volatilized by the glue in the board is pressed by the upper and lower plates, making it difficult to evaporate, which reduces the curing speed of the glue and reduces the production efficiency of the plywood. Therefore, in view of the above situation, it is urgent to develop a bamboo board rapid forming cold pressing device to overcome the shortcomings in current practical applications. Summary of the invention

[0004] The purpose of the present invention is to provide a bamboo board rapid prototyping cold pressing device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A bamboo board rapid prototyping cold pressing device comprises: a tooling table, a processing groove is arranged on the top of the tooling table, which is used to support the bamboo board; an air-conducting pressing unit, which is symmetrically arranged on the outside of the processing groove and connected to the tooling table, and is used to cooperate with the tooling table to realize the limited fixation of the bamboo board located inside the processing groove, and complete the cold pressing of the bamboo board; a circulating air blowing unit, which is arranged on the inside of the tooling table and connected to the tooling table, and is used to cooperate with the air-conducting pressing unit to realize the circulation of air inside the equipment and realize the rapid flow of air around the bamboo board; wherein, the air-conducting pressing unit comprises: a central control positioning The central control type positioning component is symmetrically arranged on the inner side of the processing groove and is connected to the workbench, and is used to cooperate with the workbench to realize the preliminary positioning of the bamboo board inside the processing groove. The central control type positioning component is also connected to the isolation type cold pressing component arranged around the outer side of the workbench. The isolation type cold pressing component is arranged relative to the processing groove, and is used to cooperate with the central control type positioning component to realize the sealing protection of the processing groove and complete the pressing of the bamboo board inside the processing groove. The isolation type cold pressing component is also symmetrically provided with auxiliary locking components, which are used to cooperate with the central control positioning component to complete the positioning and locking of the bamboo board.

[0006] Compared with the prior art, the present invention has the following beneficial effects: When the device is running, the bamboo board is placed inside the processing groove, and the central control positioning component performs preliminary limiting on the bamboo board located inside the placement groove from the left and right sides. When the central control positioning component is running, it can also drive the isolated cold pressing component to move to the side close to the processing groove. The isolated cold pressing component is connected to the workbench to complete the sealing protection of the processing groove. At this time, the circulating air blowing unit can realize the circulating flow of air inside the processing groove, and the auxiliary locking component limits the bamboo board from the front and back sides, and cooperates with the central control positioning component to complete the positioning and locking of the bamboo board, thereby ensuring the stability of the bamboo board during processing. The central control positioning component continues to operate, and the isolated cold pressing component cold presses the locked bamboo board to effectively improve the quality of cold pressing. The central control positioning component, the isolated cold pressing component and the auxiliary locking component can not only complete the clamping of the bamboo board, but also cooperate with the circulating air blowing unit to effectively control the air around the bamboo board. The invention relates to a method for effectively guiding the flow of glue, so as to prevent the solvent volatilized from the glue in the board from being pressed by the upper and lower plates and being difficult to volatilize, thereby improving the curing speed of the glue and accelerating the production efficiency of the plywood. Compared with the prior art, the plywood in the present invention is usually formed by a cold press, and the cold press is used to press the board coated with glue for one day until the glue is air-dried, which has low production efficiency. In the actual air-drying process, the solvent volatilized from the glue in the board is pressed by the upper and lower plates and is difficult to volatilize, thereby reducing the curing speed of the glue and lowering the production efficiency of the plywood. By setting an air-guiding pressing unit and cooperating with a circulating air blowing unit, the glue can be dried quickly, and multiple fixations of the bamboo board can be completed during cold pressing, thereby ensuring the stability of the bamboo board during processing, and realizing the rapid flow of air around the bamboo board during air drying, thereby accelerating the evaporation of the solvent, improving the curing speed of the glue and accelerating the production efficiency of the bamboo board.
