Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machine equipment, in particular to a gluing mechanism of a wood edge banding machine. Background Art

[0002] Edge banding machine is a kind of equipment used for wood processing, mainly used for edge banding of wood. Its main function is to trim, seal and polish the edge of wood to enhance the beauty of wood and prevent quality problems caused by edge wear in subsequent use. By edge banding the edge of wood, the overall quality and appearance of wood can be improved, and it is widely used in furniture manufacturing, architectural decoration and other fields.

[0003] However, in the edge banding process, gluing is an important step. The glue can be sprayed on the edge of the wood through the equipped spraying mechanism. In order to ensure that there will be no overflow due to glue spraying in the subsequent edge banding process, it is necessary to ensure that the glue is sprayed evenly and concentrated in the middle of the edge of the board.

[0004] However, the existing spraying mechanism is often fixed on the edge banding machine, which cannot automatically detect the thickness of the wood, and adaptively adjusts the spraying position and glue amount according to the thickness of the wood to be edge banded. These operations often require manual adjustment, which is troublesome and inconvenient.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original edge banding machine gluing mechanism. Utility Model Content

[0008] Preferably, the side plate is provided with a pit on the end face of one side close to the shell, and grooves are opened on the upper and lower sides of the pit inside the side plate to facilitate the entry and circulation of hot air, and the pit is used for rotatably installing the compaction guide wheel. Each of the compaction guide wheels is a hollow structure, and the upper and lower ends of each compaction guide wheel are respectively connected to the upper and lower grooves in the side plate.

[0009] Preferably, the nozzle structure includes a nozzle mouth, a box body, a return spring, and a valve block. The glue furnace is connected to the nozzle mouth through a delivery pipe, and the outer wall of the nozzle mouth is connected to the box body. The box body is connected to a return spring, and the end of the return spring is connected to the valve block. The valve block is used to seal and control the liquid output size of the nozzle.

[0010] Preferably, the detection and pressure structure includes an L-shaped frame, a roller frame, a counterweight, and a connecting rod. The top of the shell is connected to the L-shaped frame, and the lateral area of ​​the L-shaped frame is slidably connected to the roller frame. The upper end of the roller frame is connected to the counterweight, and the outer wall of the counterweight is rotatably connected to the connecting rod, and the connecting rod is rotatably connected to the adjustment structure.

[0011] Preferably, the adjustment structure includes a recessed frame, a first full-gear rotating shaft, a second full-gear rotating shaft, a movable gear rod, a movable rod, and a magnetic block. The top of the shell is connected to the recessed frame, and the first full-gear rotating shaft and the second full-gear rotating shaft are respectively connected on both sides of the inner wall of the recessed frame, and the first full-gear rotating shaft and the second full-gear rotating shaft are meshingly connected. The other side of the first full-gear rotating shaft is meshingly connected with the movable gear rod, and the upper end of the movable gear rod passes through the recessed frame and is rotatably connected to the connecting rod. A movable rod is slidably connected to the other side of the second full-gear rotating shaft in the recessed frame, and a pull rope is connected to the upper end of the movable rod, and the pull rope passes through the top pulley of the recessed frame and is wound around the industrial line wheel installed on the rotating shaft of the second full-gear rotating shaft. The outer wall of the lower end of the movable rod is connected to the nozzle structure through the mounting block, and a magnetic block is installed on the side of the recessed frame, and the magnetic block is located directly above the nozzle structure.

[0012] Preferably, the diameter of the first all-gear rotating shaft is half the diameter of the second all-gear rotating shaft.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the gluing mechanism of the wood edge banding machine, through the arrangement of the glue furnace, the heating equipment, the side plate and the compacting guide wheel, enables the device to transfer the heat heated by the glue furnace to the compacting guide wheel, thereby compacting the board in the edge banding process; the heated compacting guide wheel transfers heat to the edge banded board, which helps to speed up the curing time of the glue, making the bonding process faster and more efficient; the heating can also help to improve the penetration ability of the glue, allowing it to better penetrate and guide the wood surface that needs to be firmly bonded.

[0014] By setting up the detection and pressure structure, the adjustment structure and the nozzle structure, the device can lift the roller frame and the counterweight block on the L-shaped frame according to the different thicknesses of the wood, and the connecting rod drives the movable gear rod to move up, so that the first full-gear shaft rotates to a certain angle or number of circles. Since the diameter of the second full-gear shaft is twice that of the first full-gear shaft gear, the first full-gear shaft rotates one circle, and the second full-gear shaft rotates half a circle. The movable rod is driven by the pull rope to move up to half the distance of the movable gear rod, so that the nozzle of the nozzle is always kept in the area in the middle of the side of the board to ensure that In the process of continued edge banding, there will be no glue overflow due to glue spraying close to the edge. In addition, the upward movement of the nozzle also means that the thickness of the board is thicker, and more glue needs to be sprayed for normal edge banding. Therefore, in the process of the nozzle moving upward, the upper box body is close to the magnetic block, and the magnetic attraction of the magnetic block to the valve block gradually increases and is greater than the reset spring, thereby attracting the valve block to move into the box body, reducing the obstruction space of the pipeline in the nozzle, so that the nozzle can spray a larger dose of glue onto the wood, thereby achieving adaptive adjustment of the glue spraying position and glue dosage to achieve the best edge banding effect.
