Description

Technical Field

[0001] This utility model belongs to the field of plywood production technology, and in particular relates to an edge grinding device for plywood. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers, with the grain direction of adjacent veneers perpendicular to each other. During the processing of plywood, a sanding process is required to shape the surface and edges of the board to meet quality standards.

[0003] In plywood production, grinding equipment typically drives a grinding disc to grind the sides of the plywood. The plywood is usually placed on top of a conveyor belt, which then carries it into the grinding chamber. During this process, it's crucial to ensure the plywood's centerline aligns with the conveyor direction; otherwise, the plywood may collide with the outside of the grinding chamber. Therefore, a plywood edge-grinding device is needed to position and correct the plywood before grinding the sides, ensuring it enters the grinding chamber straight and preventing collisions. Utility Model Content

A vertical rod 16 is rotatably connected to the end of the support rod 15. The vertical rod 16 is fixedly connected to the straight plate 4.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates an embodiment of an edge-grinding device for plywood, comprising a conveyor belt 1; a side-grinding chamber 2 is mounted on the surface of the conveyor belt 1, and a control box 3 is bolted to the side of the side-grinding chamber 2; a straight plate 4 is provided on the top of the conveyor belt 1, and a rectangular groove 5 is formed on the top of the straight plate 4; a positioning block 6 is welded to the top of the conveyor belt 1; an infrared sensor 8 and a base plate 9 are fixedly mounted on the bottom of the conveyor belt 1; a rotating column 10 is rotatably connected to the bottom of the base plate 9; a turntable 11 is fixedly connected to the bottom end of the rotating column 10; a gear 12 is fixedly connected to the surface of the rotating column 10; and the bottom of the base plate 9... An electric telescopic rod 13 is fixedly installed. A rack 14 is fixedly connected to the output end of the electric telescopic rod 13. The rack 14 meshes with a gear 12. A support rod 15 is rotatably connected to the surface of the turntable 11. A vertical rod 16 is rotatably connected to the end of the support rod 15.

The movement of the rack 14 is limited by the limit block 17, which prevents the rack 14 from shaking during movement and thus improves the stability of the rack 14.

[0028] Working Principle: When using this invention, the user places the plywood on top of the conveyor belt 1. At this time, the infrared sensor 8 detects the material entering from the top of the conveyor belt 1 and transmits the signal to the control box 3. Subsequently, the control box 3 controls the electric telescopic rod 13 to open, so that the electric telescopic rod 13 drives the rotating column 10 to rotate through the cooperation of the rack 14 and the gear 12. Then, the turntable 11 rotates and drives the straight plate 4 to correct the plywood through the cooperation of the support rod 15 and the vertical rod 16. During this process, the movement of the straight plate 4 can be limited by the cooperation of the rectangular groove 5 and the positioning block 6, so as to avoid the straight plate 4 shaking during movement. Then, the side grinding chamber 2 grinds the side of the plywood entering its inner cavity. It should be noted that this is the prior art and will not be described in detail here. It realizes the positioning and correction of the plywood before the side grinding, so as to ensure that the plywood enters the grinding chamber straight, thereby improving the yield of the plywood appearance.

[0029] In summary, this edge-grinding equipment for plywood uses an infrared sensor 8 to detect the material feed at the top of the conveyor belt 1. Subsequently, the control box 3 controls the electric telescopic rod 13, which in turn rotates the turntable 11. Through the cooperation of the support rod 15 and the vertical rod 16, the straight plate 4 is driven to correct the plywood. This achieves the purpose of positioning and correcting the plywood before side-grinding, ensuring that the plywood enters the grinding chamber straight, thereby improving the yield of plywood with good appearance.
