Description

Technical Field

[0001] This utility model relates to the field of plywood production, specifically to a deburring device for plywood production. Background Technology

[0002] Plywood is a sheet material consisting of three or more layers of wood, which are rotary-cut into veneers or sliced ​​into thin sheets and then glued together with adhesive. It usually uses an odd number of veneer layers, with the fiber directions of adjacent veneers perpendicular to each other. During the manufacturing and processing of plywood, burrs may occur. The harmfulness of burrs is particularly obvious, which has gradually attracted widespread attention, and people have begun to study the formation mechanism and removal methods of burrs.

[0003] According to publicly available patent CN221871429U, a deburring device for plywood production includes a mounting frame, a first motor, pulleys, a flat belt, and rollers. The first motor is connected to the front left side of the mounting frame, and two pulleys (front and rear) are connected to the upper left side of the mounting frame. The output shaft of the first motor is connected to the pulleys on the same side, and a flat belt is wound between the pulleys. Rollers are rotatably connected to both the front and rear sides of the upper side of the mounting frame. In the process of developing this utility model, the inventors discovered that at least the following problems remain unsolved in the prior art. Through [further details needed], [they] [addressed these issues]. A servo motor drives a gear on the same side to rotate, which in turn rotates the first brush roller. This causes the plywood to move forward through the brush roller, achieving automatic deburring of the plywood and improving deburring efficiency. However, in traditional systems, the distance between the two first brush rollers is fixed, making it inconvenient to deburr plywood of different thicknesses, reducing the applicability of the deburring equipment. Furthermore, deburring plywood generates a large amount of dust, which can be easily inhaled by personnel, causing injury or polluting the working environment. Therefore, a new technical solution is needed to address these issues. Utility Model Content

Detailed Implementation

[0019] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A deburring device for plywood production, see [link to example]. Figures 1 to 3The system includes a frame 1, with a belt conveyor 63 installed inside the frame 1. Two mounting plates 3 are installed at one end of the frame 1, and a lower brush roller 4 and an upper brush roller 35 are positioned between the two mounting plates 3. Each mounting plate 3 has an adjusting groove 31, and an adjusting block 32 is slidably connected within each adjusting groove 31. The lower brush roller 4 is rotatably connected between the two mounting plates 3, and the upper brush roller 35 is rotatably connected between the two adjusting blocks 32. A driven component is connected to the same end of both the upper brush roller 35 and the lower brush roller 4. The sprocket 23 has a lead screw 33 rotatably connected to the bottom of the inner cavity of one of the adjusting grooves 31, and the adjusting block 32 is threaded onto the outside of the lead screw 33. The top of the lead screw 33 passes through and rests on the top of the mounting plate 3. An adjusting mechanism is provided at one end of the outer side of the frame 1. A first drive motor 2 is provided on the adjusting mechanism. The drive end of the first drive motor 2 is equipped with a drive sprocket 21. A chain 22 is provided between the drive chain and the two driven sprockets 23. The adjusting mechanism includes a sliding groove 11 opened at one end of the outer side of the frame 1 and an opening... A rectangular hole 13 is provided at the top of the frame 1, which is connected to a slide groove 11. A slider 12 is slidably connected in the slide groove 11. The first drive motor 2 is mounted on the slider 12. A fixing bolt 14 is provided in the rectangular hole 13, and the fixing bolt 14 is threadedly connected to the surface of the slider 12. During operation, the fixing bolt 14 is first loosened according to the thickness of the plywood, and then the screw 33 is turned to guide the movement in the adjusting groove 31 in conjunction with the adjusting block 32, thereby adjusting the distance between the upper brush roller 35 and the lower brush roller 4. Then, by adjusting the position of the first drive motor 2 in the slide groove 11 through the slider 12, the chain 22 is brought to a taut state. Then, the fixing bolt 14 is tightened to limit the slider 12. Then, by starting the first drive, the active sprocket 21 is driven to rotate. In conjunction with the chain 22 and the driven sprocket 23, the upper brush roller 35 and the lower brush roller 4 are driven to rotate simultaneously to transport the plywood and remove burrs from both ends. This facilitates the deburring of plywood of different thicknesses and further improves the applicability of the deburring equipment.

[0021] For details, see Figure 1 and Figure 2 A lower collection cover 5 is installed between the bottoms of the two mounting plates 3, and an upper collection cover 51 is installed on the top of the upper brush roller 35. The upper collection cover 51 is connected to the adjusting block 32 by a connecting block 34. A negative pressure collection box 53 is installed at the end of the frame 1 away from the adjusting mechanism. A conduit 52 connects the upper collection cover 51 and the lower collection cover 5, and a suction pipe 54 connects the negative pressure collection box 53 and the conduit 52. When deburring the plywood, a negative pressure pump (existing technology, not shown) creates negative pressure in the negative pressure collection box 53, thereby collecting the dust generated during deburring of both ends of the plywood in the negative pressure collection box 53 in conjunction with the upper collection cover 51 and the lower collection cover 5. This not only prevents dust from being inhaled by personnel and causing injury, but also prevents dust from splashing and polluting the working environment.

[0022] Further, see Figure 2 Multiple inverted U-shaped frames 61 are mounted on the surface of the frame 1. Two correction plates 6 are arranged between the multiple inverted U-shaped frames 61. A second drive motor 7 is installed at the end of each correction plate 6 near the upper brush roller 35. A side brush roller 71 is installed at the drive end of each second drive motor 7. The two correction plates 6 can correct the plywood during deburring, thereby preventing the plywood from shifting and affecting the deburring process. At the same time, the side brush roller 71 contacts the two ends of the plywood. Then, the second drive motor 7 is started to drive the side brush roller 71 to rotate, thereby deburring the two ends of the plywood and further improving the deburring effect of the plywood.

[0023] It is worth noting that, see Figure 2 Both correction plates 6 have bolts 62 running through them. The bolts 62 contact the inverted U-shaped frame 61 and are threadedly connected to the correction plates 6. When the position of the correction plates 6 is adjusted, the bolts 62 are turned to contact the surface of the inverted U-shaped frame 61, which facilitates the limiting of the adjusted correction plates 6.
