Description

Technical Field

[0001] This invention relates to the field of veneer processing technology, specifically to a pressing device for processing solid wood veneers. Background Technology

[0002] Solid wood veneers are widely used in furniture production. There are two types of solid wood veneers: curved veneers and flat veneers. Curved veneers require a pressing device for shaping during processing. Usually, the solid wood veneer is first placed in a steaming chamber for high-temperature steaming to increase the lignin content and moisture content. Then, before cooling down, it is quickly placed in a cold press for pressing and shaping. After pressing the veneer to the target curvature, it is held under pressure for a period of time until the curved veneer is shaped.

[0003] Currently available solid wood veneer pressing devices typically require placing the steamed solid wood veneer between an upper and lower pressure mold during operation. A hydraulic system then presses the upper mold onto the solid wood veneer for cold pressing. However, during the cold pressing process after steaming, the high-frequency vibration and increased pressure cause resin in the solid wood veneer structure to seep out. This seeped resin easily flows onto the mold, causing the solid wood veneer to stick to the lower pressure mold. This makes demolding difficult after cold pressing. Therefore, a pressing device for solid wood veneer processing is needed to solve this problem. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pressing device for solid wood veneer processing, comprising a high-frequency cold pressing machine, a support baffle plate fixedly installed on the high-frequency cold pressing machine, and a second fixed frame slidably installed on the support baffle plate. The support baffle plate has a wave-shaped groove, which is a wave-shaped recess. A second guide rod is slidably installed within the wave-shaped groove. One end of the second guide rod is fixedly connected to the second fixed frame. A wire brush is fixedly installed on the outer wall of the second fixed frame. A first ball bearing is rotatably installed on the second fixed frame. A connecting rod is fixedly connected to the outer wall of the first ball bearing. A fixing plate is fixedly connected to the connecting rod. A torsion spring is sleeved on the connecting rod. One end of the torsion spring is fixedly connected to the outer wall of the fixing plate, and the other end of the torsion spring is fixedly connected to the outer wall of the second fixed frame.

[0005] Preferably, a limiting plate for limiting the position of the second guide rod is fixedly connected to the second guide rod, and a limiting track groove is formed on the inner wall of the wave track groove. The limiting plate is slidably installed in the limiting track groove, and the track of the limiting track groove matches the track of the wave track groove.

[0006] Preferably, the inner wall of the wave track groove is fixedly connected with a plurality of evenly distributed abutment blocks, the abutment blocks are configured as hemispherical blocks, and a second ball bearing is rotatably installed at the end of the second guide rod.

[0007] Preferably, a plurality of evenly distributed air blowers are fixedly installed on the second fixed frame.

[0008] Preferably, a fixing plate is fixedly connected to the high-frequency cold press, and an inclined guide plate is fixedly connected to the fixing plate.

[0009] Preferably, an electric telescopic rod is fixedly installed on the supporting enclosure plate, and the output end of the electric telescopic rod is fixedly connected to one end of the connecting rod.

[0010] Preferably, the high-frequency cold press is fixedly connected to multiple first guide rods, one end of each first guide rod is fixedly connected to a first fixed frame, a hydraulic telescopic cylinder is fixedly installed on the first fixed frame, the output end of the hydraulic telescopic cylinder is fixedly connected to a pressure-holding upper mold, and the pressure-holding upper mold is slidably installed on the first guide rod.

[0011] Preferably, a high-frequency vibrator is fixedly installed on the pressure-holding mold, and an arc-shaped cold-pressing plate is sleeved on the outer wall of the high-frequency vibrator, the arc-shaped cold-pressing plate being configured with an arc shape.

[0012] Preferably, a support block is fixedly connected to the first guide rod, and a pressure-holding lower mold is fixedly connected to the outer wall of the support block.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In this invention, multiple air blowers are activated. After the wire brush scrapes the surface of the arc-shaped concave surface, the air blowers blow air towards the arc-shaped concave surface to clean up some debris left after scraping. The air blowers also swing back and forth and up and down with the second fixed frame to further increase the cleaning range and uniformity of the air blowing on the surface of the arc-shaped concave surface.

[0016] 2. In this invention, when the second fixed frame is scraping the arc-shaped concave surface with a wire brush, it will also swing back and forth in the horizontal direction to further scrape the arc-shaped concave surface in different scraping directions, thereby further cleaning the resin and wood chips with different degrees of adhesion.

[0017] 3. In this invention, when the second fixed frame swings up and down, it moves the wire brush up and down synchronously. At this time, the wire brush moves horizontally along the surface of the arc-shaped concave surface to scrape, while one side of the wire brush is pressed down and lifted up. When one side of the wire brush is pressed down, it presses the wire brush on that side against the surface of the arc-shaped concave surface to scrape, increasing the scraping pressure. When one side of the wire brush is lifted up, the other side is pressed down and pressed against the surface of the arc-shaped concave surface, increasing the scraping pressure and further cleaning the resin and wood chips adhering to the surface of the arc-shaped concave surface.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: This example addresses the problem that during cold pressing of bamboo and wood, resin in the solid wood structure easily seeps out. This seeped resin can easily flow onto the mold, causing the solid wood veneer to stick to the pressure-holding mold 12. This results in difficulty in demolding after cold pressing. Please refer to [link to relevant documentation]. Figure 1 - Figure 9 A pressing device for solid wood veneer processing includes a high-frequency cold press 1, a support baffle 32 fixedly mounted on the high-frequency cold press 1, and a second fixing frame 21 slidably mounted on the support baffle 32. The support baffle 32 has a wave-shaped groove 28, which is a wave-shaped recess. A second guide rod 24 is slidably mounted inside the wave-shaped groove 28. One end of the second guide rod 24 is fixedly connected to the second fixing frame 21. A wire brush 27 is fixedly mounted on the outer wall of the second fixing frame 21. When the resin in the solid wood veneer is pressed, some overflows, and the resin easily adheres to the surface of the arc-shaped concave surface 31. As the second fixed frame 21 slides along the surface of the arc-shaped concave surface 31 with the wire brush 27, the wire brush 27 can scrape the resin and wood chips adhering to the surface of the arc-shaped concave surface 31, removing the dried resin adhering to the surface of the arc-shaped concave surface 31. A first ball bearing 22 is rotatably mounted on the second fixed frame 21. A connecting rod 18 is fixedly connected to the outer wall of the first ball bearing 22. A fixing plate 19 is fixedly connected to the connecting rod 18. A torsion spring 20 is sleeved on the connecting rod 18. One end of the torsion spring 20 is fixedly connected to the outer wall of the fixing plate 19, and the other end of the torsion spring 20 is fixedly connected to the outer wall of the second fixed frame 21.

[0031] A limiting plate 26 for limiting the position of the second guide rod 24 is fixedly connected to the second guide rod 24. A limiting track groove 29 is opened on the inner wall of the wave track groove 28. The limiting plate 26 is slidably installed in the limiting track groove 29. The track of the limiting track groove 29 matches the track of the wave track groove 28.

[0032] A fixed plate 13 is fixedly connected to the high-frequency cold press 1, and an inclined guide plate 14 is fixedly connected to the fixed plate 13.

[0033] An electric telescopic rod 17 is fixedly installed on the supporting enclosure plate 32, and the output end of the electric telescopic rod 17 is fixedly connected to one end of the connecting rod 18.

[0034] Multiple first guide rods 7 are fixedly connected to the high-frequency cold press machine 1. A first fixed frame 3 is fixedly connected to one end of the first guide rod 7. A hydraulic telescopic cylinder 4 is fixedly installed on the first fixed frame 3. A pressure holding upper mold 8 is fixedly connected to the output end of the hydraulic telescopic cylinder 4. The pressure holding upper mold 8 is slidably installed on the first guide rod 7.

[0035] A high-frequency vibrator 10 is fixedly installed on the pressure-holding mold 8. An arc-shaped cold-pressing plate 9 is sleeved on the outer wall of the high-frequency vibrator 10. The arc-shaped cold-pressing plate 9 is designed with an arc shape.

[0036] A support block 11 is fixedly connected to the first guide rod 7. A pressure-holding lower mold 12 is fixedly connected to the outer wall of the support block 11. An arc-shaped concave surface 31 is opened on the surface of the pressure-holding lower mold 12. The arc-shaped concave surface 31 is set as a concave surface, and the outer contour of the arc-shaped concave surface 31 matches the outer contour of the arc-shaped cold press plate 9.

[0037] A control panel 2 is fixedly installed on the high-frequency cold press machine 1, a control console 5 is fixedly installed on the high-frequency cold press machine 1, and an emergency stop button 6 is fixedly installed on the high-frequency cold press machine 1.

[0038] In this embodiment: When using the pressing device for solid wood veneer processing, the solid wood veneer after high-temperature steaming is first placed on the pressure-holding mold 12. It should be noted that the solid wood veneer should not have cooled down after steaming at this time. At this time, the internal moisture content and lignin content of the solid wood veneer are relatively high, which is convenient for cold pressing and shaping.

[0039] Align the outline of the solid wood veneer with the curved concave surface 31 and place it; after placement, control the hydraulic telescopic cylinder 4 to start through the console 5 and control panel 2. After the hydraulic telescopic cylinder 4 starts, it moves the pressure holding upper mold 8 at the output end downward. When the pressure holding upper mold 8 moves downward, it is guided by multiple first guide rods 7.

[0040] When the pressure-holding mold 8 moves down, it moves down synchronously with the arc-shaped cold-press plate 9 and the high-frequency vibrator 10. As the arc-shaped cold-press plate 9 continues to move down, it eventually presses onto the solid wood veneer. At this time, the high-frequency vibrator 10 is activated. When the solid wood veneer bends at the point where it is pressed, the high-frequency vibrator 10 can emit high-frequency micro-vibrations, which can make the solid wood veneer that has been cold-pressed and bent fit more closely to the upper and lower molds. At this time, the pressed solid wood veneer gradually bends and deforms into the arc-shaped concave surface 31.

[0041] After the curved cold press plate 9 presses the solid wood veneer completely into the curved concave surface 31, the extension end of the hydraulic telescopic cylinder 4 remains in this state, so that the curved cold press plate 9 continues to press down on the solid wood veneer, and continuously maintains pressure on the deformed solid wood veneer. At this time, the high-frequency vibrator 10 continues to operate to perform micro-vibration, so that the deformed solid wood veneer is shaped.

[0042] It should be noted that if any substandard solid wood veneer breaks during the cold pressing process, the entire high-frequency cold pressing machine 1 can be stopped by pressing the emergency stop button 6, allowing staff to quickly remove the broken solid wood veneer.

[0043] After cold pressing, the electric telescopic rod 17 can be activated. The output end of the electric telescopic rod 17, along with the connecting rod 18 and the second fixed frame 21, moves synchronously. The outer contour of the second fixed frame 21 matches the contour of the arc concave surface 31. Therefore, the second fixed frame 21 can conform to the outer contour of the arc concave surface 31 and push the solid wood veneer inside the arc concave surface 31, pushing the solid wood veneer towards the fixed plate 13. The pushing action helps the solid wood veneer to detach from the adhesive position caused by resin overflow, making it easier for the solid wood veneer to be demolded from the pressure mold 12. The solid wood veneer finally slides down the inclined surface of the guide plate 14. A collection box can be set below the end of the guide plate 14 for collection.

[0044] During the cold pressing process, some of the resin in the solid wood veneer is easily squeezed out and adheres to the surface of the arc concave surface 31. At this time, as the second fixed frame 21 slides along the surface of the arc concave surface 31 with the wire brush 27, the wire brush 27 can scrape the resin and wood chips adhering to the surface of the arc concave surface 31 and remove the resin adhering to the surface of the arc concave surface 31.

[0045] When the second fixed frame 21 moves, the second guide rod 24 on the second fixed frame 21 moves accordingly. The second guide rod 24 slides along the inner wall of the wave track groove 28. Since the wave track groove 28 is designed as a wavy groove with up-and-down bending, the second guide rod 24 is guided by the wave track of the wave track groove 28 as it slides along it, causing the second guide rod 24 to experience intermittent up-and-down reciprocating force. After being subjected to this force, the second guide rod 24 moves one side of the second fixed frame 21 up and down synchronously. This intermittent up-and-down reciprocating oscillation of one side of the second fixed frame 21 causes the second fixed frame 21 to move along the first ball bearing 22. The rotating mounting point swings up and down repeatedly. When the second fixed frame 21 swings up and down, it moves the wire brush 27 up and down synchronously. At this time, the wire brush 27 moves horizontally along the surface of the arc concave surface 31 to scrape, while one side of the wire brush 27 is pressed down and lifted up. When one side of the wire brush 27 is pressed down, it presses the wire brush 27 on the surface of the arc concave surface 31 to scrape, and the scraping pressure increases. When one side of the wire brush 27 is lifted up, the other side is pressed down and pressed against the surface of the arc concave surface 31, and the scraping pressure increases, further cleaning the resin and wood chips adhering to the surface of the arc concave surface 31.

[0046] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1 - Figure 9 The inner wall of the wave track groove 28 is fixedly connected with a plurality of evenly distributed abutment blocks 30, which are set in a hemispherical shape, and the end of the second guide rod 24 is rotatably mounted with a second ball bearing 25.

[0047] Multiple evenly distributed air blowers 23 are fixedly installed on the second fixed frame 21.

[0048] In this embodiment: as follows Figure 5As shown, the second guide rod 24 is fixed near the side of the second fixed frame 21. Therefore, when the second guide rod 24 slides along the wave track groove 28, the second ball 25 will intermittently contact the surface of the contact block 30 in the wave track groove 28 as it slides along it. This contact causes the second ball 25 to slide along the surface of the contact block 30. Since the contact block 30 is a spherical block, the second ball 25 will move a small distance away from the contact block 30. The movement of the second ball 25 causes the second guide rod 24 and the second fixed frame 21 to move synchronously, which causes the side of the second fixed frame 21 to be subjected to force, thus causing the second guide rod 24 to move. At this time, the second fixed frame 21 deflects horizontally along the rotating mounting point of the first ball 22. During the deflection, the torsion spring 20 is bent and stored. As the second ball 25 slides past the single abutment block 30, the torsion spring 20 returns to its original position, causing the second fixed frame 21 to swing back and forth to its original position. During this process, since there are multiple abutment blocks 30, the second fixed frame 21 will also swing back and forth horizontally while scraping the surface of the arc concave surface 31 with the wire brush 27, further scraping the arc concave surface 31 in different directions, and further cleaning the resin and wood chips with different degrees of adhesion.

[0049] As the second fixed frame 21 moves along the surface of the arc-shaped concave surface 31, multiple air blowers 23 can be activated. After the wire brush 27 scrapes the surface of the arc-shaped concave surface 31, the air blowers 23 will blow air towards the arc-shaped concave surface 31 to clean up some debris left after scraping. The air blowers 23 also swing back and forth and up and down with the second fixed frame 21, further increasing the range and uniformity of the air blowing on the surface of the arc-shaped concave surface 31.
