Description

Technical Field

[0001] The present invention relates to the technical field of plywood production, and specifically relates to a plywood pressing overflow glue cleaning device. Background Art

[0002] Plywood is a three-layer or multi-layer plate-like material made by slicing wood segments into veneers or planing wooden squares into thin woods, and then gluing them with adhesives. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are perpendicular to each other for gluing.

[0003] When plywood is produced, a board blank formed by arranging veneers coated with glue in a criss-cross pattern along the grain direction is pressed under cold pressing or hot pressing processes. When the pressing plate moves down to press the plywood, the glue between the veneers will overflow and needs to be cleaned. Cleaning during pressing has certain safety hazards, and there are limiting devices on the sides of the plywood during pressing, which block the cleaning position. Currently, mainly the plywood is cleaned separately after pressing is completed. This method requires fixing the plywood again, with cumbersome operations and low work efficiency. Moreover, the overflowed glue solidifies when transferred to the cleaning device, increasing the cleaning difficulty. Summary of the Invention

[0004] The purpose of the present invention is to provide a plywood pressing overflow glue cleaning device to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A plywood pressing overflow glue cleaning device, including a workbench, a frame and a pressing mechanism. The pressing mechanism is arranged on the frame and above the workbench. The surface of the workbench is provided with limiting plates and a glue scraping mechanism. Four limiting plates are provided, and two in a group are respectively arranged in the length direction and width direction of the workbench. The two limiting plates in each group are symmetric with respect to the center of the workbench. Through grooves leading to the inside of the workbench are arranged in the length direction and width direction of the workbench surface. The lower part of the limiting plate extends into the workbench through the through groove. A driving mechanism is arranged inside the workbench, and the driving mechanism is connected to the limiting plate to drive the two limiting plates in each group to approach or move away from each other along the through groove. Grooves are arranged on the opposite sides of each group of limiting plates. The glue scraping mechanism includes a glue scraping motor, a lead screw, a slider and a glue scraping knife. The glue scraping motor is arranged at one end of the limiting plate. The output of the glue scraping motor extends into the groove and is connected to the lead screw. The lead screw rotates in the groove. The slider is threadedly connected to the lead screw and slides in the groove. A glue scraping knife is arranged on the slider.

[0006] As a preference of this technical solution, the glue scraping motor is a reversible motor. Among the two limiting plates in each group of limiting plates, the glue scraping motor is arranged at different ends of the two limiting plates. The glue scraping motors of the adjacent two limiting plates in the two groups of limiting plates are not close to each other. The glue scraping knife includes a knife holder and a scraping blade. The knife holder is fixed on the slider, and the cutting edge of the scraping blade faces both sides of the knife holder.

[0007] As an optimization of this technical solution, the driving mechanism includes a length driving mechanism and a width driving mechanism. The length driving mechanism and the width driving mechanism are arranged up and down and have the same structure. Both include a driving motor and a bidirectional lead screw. The driving motor is arranged on one side of the workbench. The output end of the driving motor is connected to the bidirectional lead screw. The bidirectional lead screw rotates within the workbench, and both ends of the bidirectional lead screw are threadedly connected to the lower part of the limiting plate.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: When pressing in the present invention, the limiting plate is used to limit the plate, and at the same time, the glue scraping mechanism on the limiting plate can scrape the glue around the plate. The overflowing glue can be scraped off during pressing, without waiting to remove the glue after pressing is completed, avoiding cumbersome work such as reinstallation and fixation. The glue can be scraped off as soon as it overflows, avoiding the difficulty of scraping after the glue solidifies. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figures 1-5, a glue overflow cleaning device for plywood pressing of the present invention includes a workbench 1, a frame 2 and a pressing mechanism 3. The frame 2 includes a support plate 21 and legs 22. The workbench 1 and the support plate 21 are both square plates. The legs 22 are provided at the four corners below the support plate 21. The support plate 21 is provided on the surface of the workbench 1 through the legs 22. The pressing mechanism 3 is arranged on the frame 2 and above the workbench 1. A limiting plate 4 and a glue scraping mechanism are arranged on the surface of the workbench 1. Four limiting plates 4 are provided, and two in a group are respectively arranged in the length direction and the width direction of the workbench 1. The two limiting plates 4 in each group are symmetric with respect to the center of the workbench 1. Through grooves leading to the inside of the workbench are arranged in the length direction and the width direction of the surface of the workbench 1. The lower part of the limiting plate 4 extends into the workbench 1 through the through groove. A driving mechanism is arranged inside the workbench 1, and the driving mechanism is connected to the limiting plate 4 to drive the two limiting plates 4 in each group to approach or move away from each other along the through groove. Grooves 4.1 are arranged on the opposite sides of each group of limiting plates 4. The glue scraping mechanism includes a glue scraping motor 5, a lead screw 6, a slider 7 and a glue scraping knife 8. The glue scraping motor 5 is arranged at one end of the limiting plate 4. The output of the glue scraping motor 5 extends into the groove 4.1 and is connected to the lead screw 6. The lead screw 6 rotates in the groove 4.1. The slider 7 is threadedly connected to the lead screw 6 and slides in the groove 4.1. The glue scraping knife 8 is arranged on the slider 7.

[0017] When the present invention is specifically implemented, the limiting plate 4 is T-shaped. The lower part of the limiting plate 4 is inserted into the inside of the workbench 1 through the through groove, and the upper part of the limiting plate 4 slides on the surface of the workbench 1. The glue scraping motor 5 is a reversible motor. Among the two limiting plates 4 in each group of limiting plates 4, the glue scraping motor 5 is arranged at different ends of the two limiting plates 4. The glue scraping motors 5 of the adjacent two limiting plates 4 in the two groups of limiting plates 4 are not close to each other. That is, in a group of limiting plates 4, the glue scraping motor 5 of one of the limiting plates 4 is arranged at the left end of the limiting plate 4, and the glue scraping motor 5 of the other limiting plate 4 is arranged at the right end of the limiting plate 4.

The glue scraping knife 8 includes a knife holder 81 and a scraper 82. The knife holder 81 is fixed on the slider 7. The cutting edges of the scraper 82 face both sides of the knife holder 81, so that when the glue scraping motor 5 rotates in two directions and the slider 7 moves in two directions, the scraper 82 can scrape the glue on the plywood 9. The groove 4.1 on the limiting plate 4 faces the center of the workbench 1. Since the plywood 9 is usually an odd number of layers, the width of the groove 4.1 is greater than the gap between two layers of veneers. Multiple grooves 4.1 can be provided, and one groove 4.1 corresponds to the gap between two layers of veneers respectively, or one groove 4.1 can be provided, and the width of this groove 4.1 covers the gaps between multiple veneers, so that the slider 7 in the groove 4.1 drives the glue scraping knife 8 to accurately remove the glue overflowing from the gap.

[0018] In the specific implementation of the present invention, the pressing mechanism includes a pressing cylinder and a pressing plate. The pressing cylinder is arranged on the support plate 21, and the output end of the pressing air pressure extends below the support plate 21 to connect the pressing plate, driving the pressing plate to move up and down. The driving mechanism includes a length driving mechanism and a width driving mechanism. The length driving mechanism and the width driving mechanism are arranged up and down on the workbench and have the same structure. Both include a driving motor 10 and a bidirectional lead screw 11. The driving motor 10 is arranged on one side surface of the workbench 1, the output end of the driving motor 10 is connected to the bidirectional lead screw 11, the bidirectional lead screw 11 rotates inside the workbench 1, and the two ends of the bidirectional lead screw 11 are threadedly connected to the lower part of the limiting plate 4.

[0019] When the present invention works, place the plywood on the surface of the workbench, start the driving mechanism inside the workbench, drive the limiting plate to limit the four side edges of the plywood, the side walls of the grooves on the limiting plate limit the board, the grooves on the limiting plate are aligned with the gaps between the veneers, start the pressing mechanism to press the plywood, glue overflows from the side edges of the plywood, start the glue scraping motor, drive the lead screw to rotate, the slider on the lead screw slides in the groove, and the scraper on the slider scrapes the glue overflowing from the side edges of the plywood. The present invention scrapes the glue during pressing. The glue overflows and has not solidified, reducing the difficulty of scraping after pressing is completed. It can also avoid the cumbersome process of reinstalling and scraping after taking out the plywood separately, improving work efficiency.

[0020] Finally, it should be noted that: the above-mentioned embodiments are only specific implementation manners of the present invention, used to illustrate the technical solutions of the present invention, rather than limiting it.
