Description

Technical Field

[0001] The utility model relates to the technical field of plywood production equipment, and in particular to a plywood pre-pressing machine with an anti-deviation structure. 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 veneers, and then gluing them together with adhesive. It is usually made with an odd number of veneers, with the fibers of adjacent layers of veneers glued perpendicular to each other.

[0003] Pre-pressing is required in the production process of plywood. Pre-pressing of plywood is a basic process in the manufacturing process. Its principle is to change the material form, reduce the volume of the slab, increase the bonding area and improve the strength of the board through pre-pressing. The main functions are as follows: improving the performance of the board. In the manufacturing process of plywood, pre-pressing can promote the natural stretching of sawdust or hemp core rods in the raw materials, so that the board has stronger stability and uniformity after forming, and improves the quality and performance of the product; increasing the bonding area, pre-pressing can generate more pressure between the sheets of the board, so that they have a tighter and firmer bonding effect, increase the bonding area of ​​the board, reduce the cracking and delamination rate of the board, and thus improve the durability and service life of the product; improving the strength of the board, pre-pressing can strengthen the overall unidirectional or bidirectional strength of the board, and increase the elastic modulus of the board, thereby improving the tensile strength, bending strength and durability of the board, making it suitable for various engineering fields requiring high strength. In general, plywood pre-pressing is an important manufacturing process for optimizing the quality and performance of plywood. The quality and service life of the product can be improved by controlling the pre-pressing time and pressure, selecting suitable raw materials and maintaining suitable environmental conditions.

[0004] In the prior art, the pre-pressing process of plywood is usually as follows: the operator first places the plywood on the pre-pressing machine by manpower or using an appropriate tool, and then starts the pre-pressing machine, and the upper pressing plate of the pre-pressing machine presses the plywood down. After pressing for a certain period of time, the upper pressing plate and the plywood are separated, and the pre-pressing of the plywood is completed. In the above process, when the plywood is placed on the pre-pressing machine, the plywood is easily offset. Utility Model Content

[0052] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0053] Reference Figure 1 and Figure 3 A plywood pre-pressing machine with an anti-deviating structure is proposed, comprising: a support platform 1 and an upper pressing plate 2 which is arranged to rise and fall relative to the support platform 1; a storage platform 3 which is arranged on one side of the support platform 1 and is used to carry plywood; an anti-deviating device 4 which has two groups, and the two groups of anti-deviating devices 4 are relatively arranged on both sides of the storage platform 3, and the anti-deviating device 4 comprises: a top plate 401 which is movable and swinging, and after the top plate 401 moves, it approaches or moves away from the side end of the plywood, and after the top plate 401 swings, it is used to abut against the side end of the plywood.

[0054] In this embodiment, the operator places the plywood on the storage table 3, and then starts the anti-deflection devices 4 on the left and right sides of the storage table 3 to work at the same time, so that the top plates 401 on both sides gradually approach the two sides of the plywood on the storage table 3. When the top plates 401 abut against the corners of the deflected plywood, the top plates 401 continue to approach the side ends of the plywood, and the top plates 401 swing at this time. When the deflected plywood is straightened, the top plates 401 abut against the side ends of the plywood, and the deviation correction process is completed. The top plates 401 swing to avoid vertical hard collision with the plywood, reduce hard collision damage to the plywood, and protect the plywood.

[0055] In this embodiment, after the operator completes the process of correcting the plywood, the top plates 401 on both sides can be abutted against the two sides of the second plywood on the storage table 3, and then the first plywood on the storage table 3 can be transported to the support table 1 using an appropriate tool, and then the upper pressing plate 2 can be pressed down on the plywood on the support table 1. After pressing for a certain period of time, the plywood on the support table 1 is taken out, and then the next plywood is transported to the support table 1 in the same way for pre-pressing. During the pre-pressing process, the anti-deflection device 4 performs the correction work, and time is reasonably used. After multiple plywoods are corrected, they can be stacked on the storage table 3.

[0056] Reference Figure 3, also includes: the top plate 401 has a hinge part 4011, the hinge part 4011 is located in the middle of one side of the top plate 401, the anti-bias device 4 also includes: a hinge rod 402, having two, one end of the two hinge rods 402 are hinged to the hinge part 4011; a slider 403, having two, the two sliders 403 move relative to each other, and the two sliders 403 are respectively hinged to the other end of the two hinge rods 402; the forward and reverse screws 404 are threadedly connected to the two sliders 403; the first drive motor 405 drives the forward and reverse screws 404 to rotate.

[0057] In this embodiment, when the operator wants to correct the plywood stacked on the storage table 3, the first drive motor 405 is first operated, and the forward and reverse screws 404 rotate, and the two sliders 403 move closer to or away from each other. At this time, the hinged rod 402 swings with the hinge position of the hinged rod 402 and the slider 403 as the swing center. After the hinged rod 402 swings, the top plate 401 moves closer to or away from the side of the plywood on the storage table 3, and the top plate 401 abuts or cancels the abutment against the side of the plywood, so that the device can adapt to plywood of different lengths, thereby improving the applicability of the device. When the top plate 401 contacts the offset plywood, the plywood swings with the hinge position of the plywood and the hinge rod 402 as the swing center, and then the first drive motor 405 continues to work until the top plates 401 on both sides abut against the two sides of the plywood. At this time, the plywood is straightened, and the swinging of the top plate 401 can effectively reduce the damage caused by a hard collision between the top plate 401 and the plywood.

[0058] Reference Figure 1~Figure 3 , and also includes: a top plate 401 is set to rise and fall relative to the storage platform 3, the anti-bias device 4 also includes: a lifting plate 406, which is set to rise and fall relative to the storage platform 3, and a first drive motor 405 is set on the lifting plate 406; a lifting screw 407 is threadedly connected to one end of the lifting plate 406; a second drive motor 408 is set on one side of the storage platform 3 to drive the lifting screw 407 to rotate.

[0059] In this embodiment, when the height of the plywood stacked on the storage table 3 is greater than the height of the top plate 401, the operator can drive the lifting screw 407 to rotate by the second drive motor 408 to raise the lifting plate 406. At this time, the anti-deviation device 4 slides in the height direction to correct the deviation of each plywood, thereby improving the applicability of the device.

[0060] Reference Figure 3 , also includes: the storage table 3 includes: a mounting frame 301, which is arranged on one side of the support platform 1, and the second driving motor 408 is arranged on the mounting frame 301; a transport roller group 302, which is arranged on the mounting frame 301, and the transport roller group 302 is used to carry the plywood.

[0062] Reference Figure 2 , further comprising: a third driving motor 5, which is arranged on the mounting frame 301 and is used to drive the transport roller set 302 to rotate.

[0063] In this embodiment, the third drive motor 5 is used to drive the transport roller group 302 to rotate, and can be used to transport the bottom layer of plywood among the multiple plywoods stacked on the transport roller group 302 to the storage table 3. For example, the top plate 401 is used to squeeze and position the second layer of plywood from the bottom, so that the plywood can be put on the platform at a small distance, and then the third drive motor 5 drives the transport roller group 302 to rotate to transport the bottom layer of plywood to the storage table 3.

[0065] In this embodiment, when the operator corrects the deflection of the plywood, the anti-deflection plate 4013 and the plywood are prevented from having a hard collision by swinging the mounting plate 4012; the anti-deflection plate 4013 is arranged on the mounting plate 4012 by plug-in connection, and the detachable structure facilitates the maintenance and replacement of the anti-deflection plate 4013. The anti-deflection device 4 can correct the deflection of the entire plywood, and can also correct the deflection of the single-layer panels stacked in a single plywood, and the principle of the correction process of a single plywood is the same. For example, when three single-layer panels are stacked up and down, one of the panels deviates outwards, the anti-deflection plate 4013 contacts the outward-deflected panel during movement and deflects, and then pushes the outward-deflected single-layer panel back to the middle position during the continued movement.

When a plurality of vacuum suction cups 104 absorb the plywood, the second oil cylinder 102 is retracted, and the mounting rod 103 rises. Then the first oil cylinder 101 is operated again, so that the second oil cylinder 102 moves to the top of the storage table 3, and then the second oil cylinder 102 is lowered to place the plywood on the storage table 3.
