[0019] Such as Figure 1As shown in the figure, a plywood trimming machine convenient for collecting waste materials includes a first conveying mechanism 1, a trimming mechanism 2, and a second conveying mechanism 3 arranged in sequence along the conveying direction. The first conveying mechanism 1 is used to convey the to-be-trimmed plates to the trimming mechanism 2, and the second conveying mechanism 3 is used to send out the trimmed plates. The first conveying mechanism 1 and the second conveying mechanism 3 are both existing mechanisms and will not be elaborated here. The trimming mechanism 2 is used to trim the two sides of the plates. The trimming mechanism 2 includes rotary cutters 22 arranged on both sides of the trimming frame 21 and pressing components arranged on both sides of the rotary cutters 22. Collection components are arranged on both sides of the second conveying mechanism 3. The collection components include two receiving troughs 4 arranged at intervals and opposite to each other along the conveying direction. The upper end and the opposite side of the receiving trough 4 are open. One of the receiving troughs 4 is fixedly connected to the trimming frame 21, and the other receiving trough 4 is connected to the frame of the second conveying mechanism 3 through an adjusting mechanism 5. The adjusting mechanism 5 is used to adjust the distance between the two receiving troughs 4. Since the receiving trough 4 is not integral but consists of two receiving troughs 4 arranged at intervals and opposite to each other, the middle part of the edge materials falling into the receiving trough 4 is not blocked, which is convenient for manual grasping and transferring the edge materials in the two receiving troughs 4. Moreover, the distance between the two receiving troughs 4 is adjustable, and the distance between the two receiving troughs 4 can be adjusted according to the length of the edge materials, so as to be applicable to the collection of edge materials of different lengths. The interface of the receiving trough 4 adopts an outward-opening flared structure, which is convenient for the center of the plates to fall.

[0020] In this embodiment, the pressing component includes a lower guide roller 26 and an upper pressing roller 27 arranged parallel to each other up and down. The lower guide roller 26 is rotatably connected to a first bearing 261 fixed on the trimming frame 21, and the upper pressing roller 27 is rotatably connected to a second bearing 271 movably arranged on the trimming frame 21. The second bearing 271 is connected to the trimming frame 21 through an elastic mechanism 28. The lower guide roller 26 is driven by a motor. The upper pressing roller 27 can move up and down driven by the elastic mechanism 28, which is applicable to the edge pressing of plates with different thicknesses.

[0021] As Figure 3 shown in the figure, among them, the elastic mechanism 28 includes a movable rod 281, a spring 282, a sleeve 283, and a fixing nut 284. An installation groove 25 is provided on the trimming frame 21. Sliding grooves for the up and down sliding of the second bearing 271 are provided on both sides of the installation groove 25. A sleeve 283 is fixed at the top of the installation groove 25. The top of the second bearing 271 is connected to the movable rod 281. The upper end of the movable rod 281 movably passes through the sleeve 283 and is threadedly connected to the fixing nut 284. The spring 282 is sleeved outside the movable rod 281. When the plate passes between the lower guide roller 26 and the upper pressing roller 27, according to the thickness of the plate, the movable rod 281 moves upward, and the spring 282 is compressed. Appropriately adjust the distance between the lower guide roller 26 and the upper pressing roller 27 to make the lower guide roller 26 and the upper pressing roller 27 cooperate to tightly press the two side edges of the plate. After the plate passes, the spring 282 resets and drives the upper pressing roller 27 to reset. This structure is applicable to the edge pressing of plates with different thicknesses.

[0022] As Figure 2 shown, in this embodiment, the adjusting mechanism 5 includes an L-shaped mounting seat 51, a threaded seat 53, a screw rod 52 and a hand wheel 54. The L-shaped mounting seat 51 is horizontally slidably connected to the guide rail 55, and the material receiving groove 4 is arranged on the L-shaped mounting seat 51. The threaded seat 53 is fixed on the side wall of the frame of the second conveying mechanism 3. The screw rod 52 is horizontally arranged, threadedly connected to the threaded seat 53, and one end thereof is rotatably connected to the L-shaped mounting seat 51, and the other end thereof extends out of the threaded seat 53 and is connected to the hand wheel 54. By rotating the hand wheel 54, the L-shaped mounting seat 51 is driven to move along the guide rail 55, facilitating the adjustment of the distance between the two material receiving grooves 4.

[0023] To facilitate the disassembly and assembly of the material receiving groove 4, a connecting seat 511 is provided on the side wall of the L-shaped mounting seat 51. A connecting groove is provided on the connecting seat 511. A clamping seat 41 that cooperates with the connecting groove is provided on the outside of the material receiving groove 4. A first through hole is provided in the connecting groove, and a second through hole corresponding to the first through hole is provided on the clamping seat 41. The "7"-shaped locking rod 6 can be inserted into the first through hole and the second through hole in sequence. When in use, after the clamping seat 41 on the material receiving groove 4 is snapped into the connecting groove, the "7"-shaped locking rod 6 can be inserted into the first through hole and the second through hole in sequence to realize the connection between the L-shaped mounting seat 51 and the material receiving groove 4, which is convenient for disassembly and assembly.

[0024] The rotary cutter 22 is of a circular structure, and a part of the rotary cutter 22 extends out of the conveying plane. The rotary cutter 22 is driven by a motor to rotate.

[0025] To prevent dust from flying during the edge cutting process, a dust removal cover 23 is provided above each rotary cutter 22. The top of the dust removal cover 23 is connected to a vacuum cleaner through a suction pipe 24, and the vacuum cleaner is arranged below the edge cutting frame 21. It can suck the dust and shavings generated during the cutting process to the greatest extent, greatly improving the working environment.

[0026] When in use, the operator places the plywood to be edge-cut on the first conveying mechanism 1. The first conveying mechanism 1 conveys the board to the edge cutting mechanism 2, and the rotary cutters 22 on both sides are used to cut the edge of the board. During the edge cutting process, the lower guide roller 26 is used to convey and cooperate with the upper pressure roller 27 to press the board, ensuring the stability of the cutting. The cut edge material moves with the board and finally falls between the two material receiving grooves 4. When the lengths of the edge materials are different, the screw rod 52 is rotated by the hand wheel 54, thereby pushing the L-shaped mounting seat 51 to move along the guide rail, so as to adjust the distance between the two material receiving grooves 4, so as to be suitable for the collection of edge materials of different lengths. When there is a large accumulation of edge materials in the material receiving groove 4, the operator grabs the edge materials from the middle between the two material receiving grooves 4, facilitating the transfer of the edge materials in the material receiving groove 4.

[0027] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are all within the protection scope of the present utility model.
