Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and in particular to a universal edge banding machine for boards of various thicknesses. Background Technology

[0002] Edge banding is a crucial process in panel furniture manufacturing and other fields. It not only enhances the aesthetics of the panels but also strengthens their durability, effectively preventing damage to the edges and corners, peeling or flaking of the veneer during transportation and use. It also provides waterproofing and reduces the release of harmful gases. Traditional edge banding machines are usually only suitable for a single or a few fixed thicknesses of panels. To process panels of different thicknesses, it is often necessary to stop the machine and manually change molds or adjust a large number of parts, which is time-consuming. Generally, the changeover and adjustment time is more than 30 minutes, which greatly affects production efficiency and increases production costs. It is especially unsuitable for small-batch, multi-specification customized production needs.

[0003] For example, the existing Chinese patent with publication number CN214163366U discloses a board edge banding machine. First, the board body is placed on the frame, the first motor is started, and the screw is driven by the first motor to move the brush plate closer to the board body until the bristles contact the edge of the board body. Then, the board body is conveyed by the conveyor chain.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the process of edge banding of boards, for boards of different thicknesses, the conveying system of existing edge banding equipment needs to adjust the spacing between the conveying rollers to adapt to the thickness of the board. When the spacing between the conveying rollers is adjusted manually or mechanically, the conveying rollers gradually move closer to one side of the board to fit together, which can easily cause an imbalance in the pressure distribution on both sides of the board. This can lead to the board tilting to one side when entering the conveying channel, resulting in edge wear and surface scratches on the board. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that when adjusting the spacing of the conveying rollers, it is easy to cause an imbalance in the pressure distribution on both sides of the board. To this end, we propose a universal edge banding machine for boards of various thicknesses.

[0006] To achieve the above objectives, this application adopts the following technical solution: a universal edge banding machine for multi-thickness boards, including an edge banding machine, the edge banding machine including a base, an edge banding table fixedly installed on the upper end of the base, a limit component installed on one side of the edge banding table, when the device is in use, by placing one side of the board on the limit component, the thickness of the board is detected in real time by a laser sensor, the data is fed back to the control system, and the pressure, height, feed speed and other parameters of the edge banding table are automatically adjusted.

[0007] Preferably, the edge banding table has a sliding groove inside. Multiple sets of hydraulic rods are fixedly installed at the upper end of the edge banding table. The driving end of the hydraulic rods passes through the edge banding table and is fixedly installed with a piston plate. The piston plate is located inside the sliding groove and matches it. Multiple sets of connecting columns are fixedly installed at the lower end of the piston plate. The lower end of the connecting columns passes through the edge banding table and is fixedly installed with a U-shaped shell. Multiple sets of conveyor rollers are rotatably installed inside the U-shaped shell. Multiple sets of conveyor rollers are provided at the lower end of the conveyor rollers. The conveyor rollers are rotatably connected to the edge banding table. After limiting one side of the board material by the limiting component, the piston plate is moved by starting the hydraulic rod. The U-shaped shell and the conveyor rollers at the lower end are pressed by the connecting column to make the U-shaped shell and the conveyor rollers at the lower end fit against the upper surface of the board material. At this time, the conveyor rollers are started to rotate and move the board material along the edge banding table for edge banding. When dealing with boards of different thicknesses, the distance between the conveyor rollers and the board material can be flexibly adjusted so that the device can adapt to edge banding of boards of various thicknesses.

[0008] Preferably, an elastic element is provided on the outer side of the connecting column, the upper end of the elastic element is fixedly connected to the piston plate, and the lower end of the elastic element is fixedly connected to the inner wall of the sealing table.

[0009] Preferably, the limiting component includes a U-shaped shell II, and multiple sets of conveying rollers III are rotatably installed inside the U-shaped shell II.

[0010] Preferably, one side of the second U-shaped shell is fixedly connected to the edge sealing table, and a slide rail is fixedly installed on the other side of the second U-shaped shell, with a clamping component slidably arranged inside the slide rail.

[0011] Preferably, the clamping assembly includes a slider that matches a slide rail. A U-shaped block is fixedly installed on the upper end of the slider. A mounting groove is formed inside the U-shaped block, and a clamping plate is rotatably installed inside the mounting groove. In the initial state, the lower end of the clamping plate is in contact with the lower inner wall of the U-shaped block. Torsion springs are fixedly installed on both sides of the rotation shaft of the clamping plate, with one end of each torsion spring fixedly connected to the U-shaped block. Two sets of electromagnets are fixedly installed on the outer ends of the U-shaped block, with one end of each electromagnet rotatably connected to the rotation shaft of the U-shaped block and the clamping plate. When edge sealing of the sheet material is required, the plate... One side of the material is pushed into the U-shaped block. Under the action of the torsion spring, the clamping plate is pushed upward and lifted, and the upper surface of the material is squeezed. Before the distance between the first conveyor roller and the material is adjusted, the electromagnet is energized and magnetically attracted to the rotating shaft of the clamping plate, thereby restricting the rotation of the clamping plate. At this time, the distance between the first conveyor roller and the material is adjusted. In this way, when the first conveyor roller squeezes one side of the material, the other side of the material is restricted, reducing the occurrence of tilting and scratching of the material during squeezing. At this time, the edge sealing table is started to move and perform edge sealing treatment on the material.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, a hydraulic rod drives a piston plate to move the connecting column and the conveying roller 1 inside the U-shaped shell up and down. With the buffering effect of the elastic element, the conveying roller 1 can adaptively conform to the upper surface of plates of different thicknesses, ensuring uniform pressure. At the same time, the conveying roller 3 in the U-shaped shell 2 of the limiting assembly forms a bidirectional constraint with the clamping assembly on the slide rail. One side of the plate is assisted by the conveying roller 3 for conveying, while the other side is squeezed on the upper surface of the plate by the clamping plate inside the U-shaped block under the elastic force of the torsion spring. The electromagnet can temporarily fix the angle of the clamping plate, forming a stable limit on the other side of the plate during the adjustment of the conveying roller 1, avoiding tilting caused by unilateral compression. The thickness of the plate is detected in real time by a laser sensor and the parameters are fed back, making the adjustment of the distance between the conveying roller 1 and the conveying roller 2 more precise. Ultimately, it achieves force balance and no tilting of plates of different thicknesses during the conveying process, reduces edge wear and surface scratches, and ensures the quality of edge sealing.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

The lower end of the connecting column 124 passes through the edge sealing table 12 and is fixedly installed with a U-shaped shell 126.

The second conveying roller 128 is rotatably connected to the edge sealing table 12. After limiting one side of the board through the limiting component 13, the piston plate 123 is moved by starting the hydraulic rod 122. The U-shaped shell 126 and the conveying roller 127 at its lower end are brought into contact with the upper surface of the board through the extrusion connecting column 124. At this time, the second conveying roller 128 is started to rotate and move the board along the edge sealing table 12 for edge sealing. When dealing with boards of different thicknesses, the distance between the conveying roller 127 and the board can be flexibly adjusted so that the device can perform adaptive edge sealing for boards of various thicknesses.

The upper end of the elastic element 125 is fixedly connected to the piston plate 123, and the lower end of the elastic element 125 is fixedly connected to the inner wall of the sealing table 12.

[0027] Reference Figure 3-4 As shown in this embodiment: the limiting component 13 includes a U-shaped shell 131, and multiple sets of conveying rollers 132 are rotatably installed inside the U-shaped shell 131.

[0028] Reference Figure 3-4 As shown in this embodiment: one side of the U-shaped shell 131 is fixedly connected to the edge sealing table 12, and the other side of the U-shaped shell 131 is fixedly installed with a slide rail 133. The slide rail 133 is slidably provided with a clamping component 134 inside.

[0029] Reference Figure 4-6As shown, in this embodiment: the clamping assembly 134 includes a slider 1341, which matches the slide rail 133. A U-shaped block 1342 is fixedly installed on the upper end of the slider 1341. A placement groove 1343 is provided inside the U-shaped block 1342. A clamping plate 1346 is rotatably installed inside the placement groove 1343. In the initial state, the lower end of the clamping plate 1346 is in contact with the lower inner wall of the U-shaped block 1342. Torsion springs 1345 are fixedly installed on both sides of the rotation shaft of the clamping plate 1346. One end of the torsion spring 1345 is fixedly connected to the U-shaped block 1342. Two sets of electromagnets 1344 are fixedly installed on both outer ends of the U-shaped block 1342. One end of the electromagnet 1344 passes through the U-shaped block 1342 and the clamping plate 1346. The rotating shaft is rotatably connected. When edge sealing is required, one side of the board is pushed into the U-shaped block 1342. Under the action of the torsion spring 1345, the clamping plate 1346 is pushed upward and lifted, pressing the upper surface of the board. Before the conveying roller 127 of the device is adjusted to the distance between itself and the board, the electromagnet 1344 is energized and magnetically attracted to the rotating shaft of the clamping plate 1346, thereby restricting the rotation of the clamping plate 1346. At this time, the distance between the conveying roller 127 and the board is adjusted. In this way, when the conveying roller 127 presses one side of the board, the other side of the board is restricted, reducing the occurrence of tilting and scratching of the board during pressing. At this time, the edge sealing table 12 is started to move and perform edge sealing on the board.

[0030] Working principle: By placing one side of the sheet material in the U-shaped shell 131 of the limiting component 13 and using the conveying roller 132 for auxiliary conveying, the other side of the sheet material is pushed into the U-shaped block 1342 of the clamping component 134. The clamping plate 1346 is lifted and pressed against the upper surface of the sheet material by the torsion spring 1345. The electromagnet 1344 is energized to attract the rotating shaft of the clamping plate 1346 to limit its rotation. The laser sensor detects the thickness of the sheet material in real time and feeds back the data. The control system adjusts the hydraulic rod 122 to drive the piston plate 123 to move in the slide groove 121. The connecting column 124 drives the U-shaped shell 126 and the conveying roller 127 to move closer to the upper surface of the sheet material. The elastic element 125 buffers the pressure to ensure uniform bonding. The conveying roller 128 is started to rotate, which drives the sheet material to move along the edge sealing table 12 for edge sealing. During this process, the clamping component 134 slides on the slide rail 133 according to the width of the sheet material, realizing stable conveying and precise edge sealing of sheets of different thicknesses and reducing tilting and scratching.
