[0001] The utility model relates to the technical field of plywood production equipment, in particular to a plywood pressing device. Background Art

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. It is usually made of an odd number of veneers, and the fibers of adjacent veneers are glued perpendicular to each other. In the process of multi-layer plywood processing, a pressing device is required to press the multi-layer boards with adhesive into one piece using a hydraulically controlled pre-pressing device.

[0003] The existing plywood pressing device is complicated to operate, which reduces the pressing efficiency. At the same time, excessive pressure during pressing causes the plywood to break, which greatly increases the scrap rate of the product and brings unnecessary board loss. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a plywood pressing device, comprising a frame, a placing table for placing plates is arranged on the frame, a pressing assembly for gluing the plates placed on the placing table is arranged above the placing table and on the frame, and a plurality of elastic supporting assemblies for supporting and limiting the pressing assembly are evenly arranged on the left and right sides of the placing table. The utility model can realize the upward elastic support operation of the pressing assembly through the elastic supporting assembly when the pressing assembly presses the plates, thereby avoiding the cracking of the plywood caused by excessive pressure during pressing, avoiding unnecessary plate loss, reducing the scrap rate, improving the pressing efficiency, and making the operation simpler and more convenient.

[0006] The pressing assembly includes a plurality of telescopic push rods arranged on a frame, wherein the telescopic push rods are hydraulic telescopic rods, and an extrusion plate is arranged at the lower part of the output rods of the plurality of telescopic push rods, and a limiting groove for limiting the position of the plate is arranged at the lower part of the extrusion plate. The utility model can push the limiting groove downward to move under the effect of the extension of the output rod of the telescopic push rod, thereby realizing the pressing together of the plates coated with adhesive pre-placed on the placing table, and the limiting groove is used to guide and limit the plates to ensure the complete overlap of the two plates bonded together.

[0007] The elastic support assembly includes an installation groove arranged on the frame, a limiting cylinder is arranged in the installation groove, a spring is arranged in the limiting cylinder, a limiting rod is arranged on the upper part of the spring and located in the limiting cylinder, a protective pad is arranged on the end of the limiting rod, and the protective pad is a hemispherical rubber pad. The utility model can realize an upward auxiliary elastic supporting force on the pressing assembly through the elastic support assembly. When the pressing assembly applies pressure downward to the plate, the spring is compressed. The compressed spring will exert an upward elastic supporting force on the limiting rod and the protective pad due to its own restoring elastic force, thereby avoiding the pressing assembly from fracturing the plate due to excessive pressure, greatly improving the yield rate of the pressing of the plate, and making the operation safer and more convenient.

[0008] A flange is provided on the outside of the limiting cylinder, and the diameter of the mounting groove is smaller than the outer diameter of the flange.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] like Figure 1-4 As shown: This embodiment provides a plywood pressing device, including a frame 100, on which a placing table 200 for placing a plate is arranged, and a pressing assembly 300 for gluing the plate placed on the placing table 200 is arranged above the placing table 200 and located on the frame 100, and a plurality of elastic support assemblies 400 for supporting and limiting the pressing assembly 300 are evenly arranged on the left and right sides of the placing table 200. The utility model can realize the upward elastic support operation of the pressing assembly 300 through the elastic support assembly 400 when the pressing assembly 300 performs the pressing operation on the plate, thereby avoiding the cracking of the plywood caused by excessive pressure during pressing, avoiding unnecessary plate loss, reducing the scrap rate, improving the pressing efficiency, and making the operation simpler and more convenient.

[0021] According to one embodiment of the utility model, Figure 1-4As shown, the pressing assembly 300 includes a plurality of telescopic push rods 301 arranged on the frame 100, the telescopic push rods 301 are hydraulic telescopic rods, and the lower part of the output rods of the plurality of telescopic push rods 301 is provided with an extrusion plate 302, and the lower part of the extrusion plate 302 is provided with a limiting groove 303 for limiting the plate. The utility model can push the limiting groove 303 downward by extending the output rod of the telescopic push rod 301, thereby realizing the pressing together of the plate coated with adhesive pre-placed on the placement table 200, and the limiting groove 303 is used to guide and limit the plate to ensure the complete overlap of the two plates bonded together.

[0022] According to another embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the elastic support component 400 includes a mounting groove 401 arranged on the frame 100, a limiting cylinder 402 is arranged in the mounting groove 401, a spring 403 is arranged in the limiting cylinder 402, a limiting rod 404 is arranged on the upper part of the spring 403 and located in the limiting cylinder 402, and a protective pad 405 is arranged at the end of the limiting rod 404, and the protective pad 405 is a hemispherical rubber pad. The utility model can realize an upward auxiliary elastic supporting force on the pressing component 300 through the elastic support component 400. When the pressing component 300 further presses the plate downward, the spring 403 is compressed. The compressed spring 403 will exert an upward elastic supporting force on the limiting rod 404 and the protective pad 405 due to its own restoring elastic force, thereby avoiding the pressing component 300 from fracturing the plate due to excessive pressure, greatly improving the yield rate of the pressing of the plate, and making the operation safer and more convenient.

[0023] According to another embodiment of the present invention, Figure 1 and Figure 3 As shown, a flange 406 is provided on the outer side of the limiting cylinder 402, and the diameter of the mounting groove 401 is smaller than the outer diameter of the flange 406.

[0024] The use of the utility model:

[0025] First of all, it should be made clear that the pressing device involved in the utility model is mainly used for the gluing of multi-layer boards. The utility model takes the gluing of plywood as an example to explain its method of use in detail. When it is necessary to glue multi-layer plywood, first place the first layer of plywood on the placing table 200, then apply adhesive on the first layer of plywood, then completely overlap and stack the second layer of plywood with the first layer of plywood, and then start the output rod of the telescopic push rod 301 to extend until it pushes the limit groove 303 to move downward until the bottom plate of the limit groove 303 squeezes the second layer of plywood. At this time, the spring 403 is compressed, and the compressed spring 403 will press the limit rod 404 due to its own restoring elastic force. The protective pad 405 provides an upward elastic supporting force, which prevents the pressing assembly 300 from fracturing the sheet material due to excessive pressure, greatly improves the yield rate of the pressing of the sheet material, and makes the operation safer and more convenient. After a period of stabilization and the glue drying, the output rod of the telescopic push rod 301 is started and retracted to a safe height, and the above action can be repeated to carry out the gluing operation of the next layer of plywood. When the pressing assembly 300 performs the pressing operation on the sheet material, the utility model can realize the upward elastic supporting operation of the pressing assembly 300 through the elastic supporting assembly 400, which prevents the plywood from being cracked due to excessive pressure during pressing, avoids unnecessary sheet material loss, reduces the scrap rate, improves the pressing efficiency, and makes the operation simpler and more convenient.
