Description

Technical Field

[0001] The utility model relates to the technical field of plywood grinding, and in particular to a double-sided edge milling device for plywood. Background Art

[0002] Plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. It is usually made of an odd number of veneers, and the fibers of adjacent veneers are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major wood-based panels. It can also be used as a material for airplanes, ships, trains, cars, buildings, and packaging boxes. A group of veneers is usually assembled and glued in such a way that the grain directions of adjacent layers are perpendicular to each other. Usually, the surface board and the inner layer board are symmetrically arranged on both sides of the center layer or the core of the board. The slabs are made by crisscrossing the veneers coated with glue in the direction of the grain, and then pressed under heating or non-heating conditions. Common types of plywood include three-ply board and five-ply board. Plywood can improve the utilization rate of wood and is a major way to save wood.

[0003] In the prior art, when processing plywood, four edges need to be polished to remove burrs so that the four edges of the plywood are milled flat. In the prior art, when the two sides of the plywood are polished, the plywood is prone to deviation. Utility Model Content

[0050] Example 1

[0051] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes a double-sided milling device for plywood, comprising:

[0052] A frame 1; a feeding device 2, which is arranged on the frame 1 and is used to transport plywood; a milling device 3, which is arranged on the frame 1, and the milling device 3 includes: a mounting plate 301, which is arranged on the frame 1; a plurality of positioning rollers 302, which are arranged in an array along the transport direction of the plywood and are rotatably arranged on the mounting plate 301, and the circumference of the positioning rollers 302 abuts against the side edges of the plywood; a milling cutter 303, which is rotatably arranged on the mounting plate 301 and is used to mill the edges of the plywood.

[0053] In this embodiment, the middle of the frame 1 has a through slot; the feeding device 2 is arranged on the frame 1, and the center line of the feeding device 2 is opposite to the center line of the through slot; the milling device 3 is arranged on the frame 1 and is located in the through slot. The operator places the plywood on the feeding device 2, and the feeding device 2 transports the plywood to the milling device 3. At this time, the side of the plywood contacts the peripheral side of the positioning roller 302. Under the action of friction, the positioning roller 302 rotates to allow the plywood to continue to be transported forward until the side of the plywood contacts the milling cutter 303. At this time, the milling cutter 303 mills the side of the plywood to make the side of the plywood smooth. The positioning roller 302 prevents the plywood from running off in the milling device 3, keeps the side of the plywood and the milling cutter 303 level, and prevents the plywood from deviating when milling.

[0054] One working form of this embodiment is: there are a plurality of positioning rollers 302, which are arranged in an array along the transport direction of the plywood and are rotatably arranged on the mounting plate 301; there are a plurality of milling cutters 303, and a milling cutter 303 is rotatably arranged between two adjacent positioning rollers 302; the plurality of positioning rollers 302 and the plurality of milling cutters 303 are arranged vertically; both ends of the milling device 3 are provided with positioning rollers 302; after the operator places the plywood on the feeding device 2, the plywood is transported to the milling device 3 by the feeding device 2, and the plywood is glued. The board first passes through the positioning roller 302 located at the head end of the milling device 3. Under the action of friction, the positioning roller 302 at the head end rotates to make the plywood close to the first milling cutter 303 for milling. Then the plywood will continue to be transported forward, and after the milling part is separated from the first milling cutter 303, it will contact the second positioning roller 302. The second positioning roller 302 grinds the milled part to ensure the flatness of the milling. At the same time, the plywood is positioned again to ensure that the plywood and the side of the milling cutter 303 are level to prevent the plywood from running off.

[0055] Another working form in the embodiment is: there are a plurality of positioning rollers 302, which are arrayed and rotatably arranged on the mounting plate 301; there is at least one milling cutter 303, which is rotatably arranged on the mounting plate 301 and is located at the rear of the plurality of positioning rollers 302; the operator places the plywood on the feeding device 2, and the plywood passes through the plurality of positioning rollers 302 in sequence under the action of the feeding device 2. At this time, the plurality of positioning rollers 302 positions the plywood to prevent the plywood from deviating. After passing through the plurality of positioning rollers 302, the plywood contacts the milling cutter 303 for edge milling.

This embodiment is different from the first embodiment in that: the milling device 3 has two groups, the plywood is located between the two groups of milling devices 3, and the two groups of milling devices 3 are relatively slidably arranged on the frame 1; it also includes: forward and reverse screws 4, which are rotatably arranged on the frame 1 and are threadedly connected with the two mounting plates 301, and are used to drive the two groups of milling devices 3 to slide relative to each other; the feeding device 2 is located between the two groups of milling devices 3.

[0058] In this embodiment, further, the milling device 3 has two groups, and the two groups of milling devices 3 are relatively and slidably arranged on the frame 1. The operator can drive the forward and reverse screws 4 to rotate to make the two groups of milling devices 3 produce relative movement, so as to mill the plywood of different widths; at the same time, the two groups of milling devices 3 are relatively and slidably arranged on the frame 1, which can better limit the plywood and better prevent the plywood from running off the track when milling.

[0059] Example 3

[0060] Reference Figure 1~Figure 4 , which is the third embodiment of the utility model. This embodiment is different from the first embodiment in that the milling device 3 also includes: a guide plate 304, which has two guide plates 304, which are relatively arranged on both sides of the mounting plate 301 in the plywood transportation direction, and the guide plates 304 are inclined relative to the mounting plate 301, so as to guide the plywood into between the two groups of milling devices 3.

[0061] In this embodiment, further, the guide plate 304 is inclined relative to the mounting plate 301, and the entrance on the side away from the mounting plate 301 is trumpet-shaped. The plywood can be adjusted before entering the milling device 3. After the offset plywood passes through the guide plates 304 on both sides, the side edges of the plywood and the side circumferences of the positioning rollers 302 and the milling cutter 303 are in a horizontal state, thereby reducing the occurrence of the plywood running off.

The support plate 8 drives the plywood to rise and fall, and the plywood is adsorbed and connected with the vacuum suction cup 10 after rising.

[0070] In this embodiment, further, after the milling of both sides of the plywood in the length direction is completed, the plywood is transported to the workbench 7, but a part of the plywood is still located in the milling device 3. At this time, the operator raises the conveying roller group 5, and then raises the supporting plate 8 through the avoidance opening 701 to lift up a part of the plywood outside the milling device 3. In this process, the friction between the bottom of the plywood and the periphery of the conveying roller 202 is reduced, which protects the plywood. When the plywood is lifted to a certain height, that is, the plywood has been completely separated from the milling device 3, at this time The plywood and the vacuum suction cup 10 are connected by adsorption, and the vacuum suction cup 10 provides a vacuum environment to make the adsorption effect better. Then the operator rotates the vacuum suction cup 10 in a circle to change the direction of the plywood, that is, the length direction of the plywood is perpendicular to the transportation direction of the plywood, and the width direction of the plywood is horizontal to the transportation direction of the plywood. Then the operator moves the two sets of milling devices 3 away from each other to adapt to the width of the plywood, and then reverses the feeding device 2, so that the plywood re-enters the milling device 3 to mill both sides of the plywood in the width direction, thereby improving the efficiency of milling.
