Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and more specifically, it relates to a double-sided synchronous edge grinding machine for wood processing. Background Technology

[0002] During the processing of wood panels, their sides often need to be sanded before they can be used. To improve sanding efficiency, the traditional single-sided sanding has been improved to the current double-sided sanding. That is, during sanding, the sander simultaneously sands two opposite sides of the wood panel. In the existing technology, this type of double-sided sander usually has sanding plates set on both sides inside a frame, and then the drive mechanism moves the wood panel between the two sanding plates, so that the two sides of the wood panel come into contact with the sanding plates, thereby achieving the effect of edge sanding.

[0003] However, in the existing double-sided synchronous edge grinding machines, the grinding plate is fixedly set on the inside of the edge grinding machine, which causes incompatibility when grinding wood boards of different sizes, affecting normal processing.

[0004] Furthermore, the lack of a cleaning structure means that after the wood is edged, a small amount of sawdust may remain on its surface. Manual cleaning of this is troublesome and reduces the edge-grinding efficiency of the wood. Utility Model Content

A dust filter plate 19 is fixedly provided on the inner wall of the collection box 16 and on one side of the negative pressure fan 18. A baffle 26 is slidably provided at the bottom of the collection box 16.

[0032] More specifically, the user can control the motor 6 to rotate the sanding roller 5 to sand the edges of the passing wooden boards. The user can also turn the handwheel 9 to move the threaded rod 8 to move the moving plate 3 and the sanding roller 5, adjusting the distance between the two sanding rollers 5 to facilitate sanding the edges of wooden boards of different sizes. When the wooden board is about to pass the bottom of the gantry 10, the negative pressure fan 18 can be turned on to create negative pressure inside the suction pipe 17 and the cleaning box 13, so that the wood chips on the wooden board are sucked into the collection box 16 through the suction hole 14 and the suction pipe 17. Afterwards, the baffle 26 can be removed to facilitate centralized cleaning of the inside of the collection box 16. The dust filter plate 19 can be set to block the wood chips to prevent them from entering the negative pressure fan 18 and affecting its service life.

[0033] Please see Figure 1 and Figure 4 As an implementation method for guiding wooden boards: a housing 20 is fixedly provided on the upper end face of the roller conveyor 1 and on both sides of the moving plate 3. A pressure plate 21 is slidably provided inside the housing 20. A pressure roller 22 is rotatably provided at the lower end of the pressure plate 21. Multiple pressure rollers 22 are provided and arranged linearly. A cylinder 23 is fixedly provided on the upper end face of the housing 20.

[0034] Specifically, when grinding the edges of a wooden board, the user can control the cylinder 23 to drive the pressure plate 21 and pressure roller 22 downwards so that they come into contact with the wooden board at the top of the roller conveyor 1, thereby guiding it and facilitating subsequent edge grinding.

[0035] Please refer to Figure 1 and Figure 5 As a further embodiment for supporting the sliding block 12 to facilitate free adjustment of the height of the cleaning box 13: each of the lower end faces of the sliding block 12 is provided with a support spring 27, and the other end of each support spring 27 is fixedly connected to the roller conveyor 1.

[0036] Specifically, the support spring 27 allows the cleaning brush 15 to adaptively adjust its height so that it can clean the sawdust on the wooden board, facilitating subsequent vacuuming.

[0037] In summary, when using the entire equipment: the user places the wooden board on the upper end of the roller conveyor 1, and then controls the cylinder 23 to move the output end of the pressure plate 21 and pressure roller 22 downwards to adjust the height of the pressure roller 22, thereby guiding the wooden board. Then, the motor 6 is turned on to rotate the grinding roller 5 so that the grinding roller 5 contacts the edge of the wooden board, thereby grinding the edge of the passing wooden board. The user can also turn the handwheel 9 to move the threaded rod 8 to move the moving plate 3 and the grinding roller 5 to adjust the two grinding rollers. The distance between 5 can be adjusted to facilitate edge grinding of wooden boards of different sizes. When the wooden board is about to pass the bottom of the gantry frame 10, the negative pressure fan 18 can be turned on to create negative pressure inside the suction pipe 17 and the cleaning box 13, so that the wood chips on the wooden board can be sucked into the collection box 16 through the suction hole 14 and the suction pipe 17. Afterwards, the baffle 26 can be removed to facilitate centralized cleaning of the inside of the collection box 16. By setting the dust filter plate 19, the wood chips can be blocked to prevent them from entering the negative pressure fan 18 and affecting its service life, so as to facilitate long-term use.

[0038] The motors mentioned above are all controlled by controllers or drivers. Since the controllers and matching equipment are common devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.
