The photoelectric sensor switch is connected to the translation motor through a wire. When the photoelectric sensor switch receives a signal, the translation motor starts to drive the movable bottom plate to move down through the screw rod ; The lower end of the connection frame near the movable base plate is provided with a limit switch, the limit switch is connected with the translation motor through a wire, and when the limit switch is triggered, the translation motor stops moving.

The utility model has a simple structure. When in use, the arc-shaped turning frame rolls 180 degrees on the base, and the plank is reversed by 180 degrees, which saves labor and improves work efficiency. The turned plank is directly transferred to the plank for sanding. Continuous sanding operation at the inlet end of the machine.

Detailed ways

Below in conjunction with accompanying drawing and embodiment concretely set forth the content of the utility model.

The utility model solves the above technical problems through the following technical solutions:

A wood turning machine, comprising a square base 1 and an arc-shaped turning frame 2 placed on the base 1, two rotating shafts 11, 12 are arranged in parallel on the base 1, and the two ends of the rotating shafts 11, 12 are respectively equipped with A runner 13,14,15,16, wherein a rotating sprocket 17,18 is installed on one of the rotating shafts 11; the rotating shaft 11 on which the rotating sprocket 17,18 is installed on the base 1 is connected with the turning motor 19; Shape overturn frame 2 is placed on runner 13,14,15,16; The outer side of arc shape overturn frame 2 is also provided with the chain 21 that matches with rotating sprocket 17,18; There is a U-shaped material-bearing platform 22; the U-shaped material-bearing platform 22 is composed of a fixed base plate 221, a movable base plate 222 and a connecting frame 223, the movable base plate 222 is provided with screw holes, and the connecting frame 223 is fixedly provided with a screw mandrel 224, The screw mandrel 224 is connected with the screw hole on the movable bottom plate 222; the side of the movable bottom plate 222 close to the connecting frame 223 is also fixedly equipped with a balance shaft 2221, and a balance gear 2222 is respectively installed on the two ends of the balance shaft 2221, and the A balance tooth 2231 matching the balance gear 2222 is installed on the side of the connection frame 223; a sliding groove 2232 is also provided on both sides of the connection frame 223, and a pulley 2223 matching the sliding groove 2232 is provided on both sides of the movable bottom plate 222 One end of screw mandrel 224 is equipped with translational motor 2241, is provided with photoelectric sensor switch 2233 near the upper end of fixed base plate 221 in connecting frame 223, photoelectric sensor switch 2233 links to each other with translation motor 2241 by wire, after photoelectric sensor switch 2233 receives signal , the translation motor 2241 starts to drive the movable base plate 222 to move downward through the screw rod 224; Afterwards, translation motor 2241 stops moving.

When working, first turn the arc-shaped turning frame through the turning motor, so that the 匚-shaped material receiving platform remains horizontal and at the same time control the movable bottom plate to be placed under the fixed bottom plate, and then use the translation motor to drive the screw to drive the movable bottom plate to be aligned with the working platform of the sander. Flat, the photoelectric sensor switch is fixed on the connection frame and is at the same height as the sander workbench. When the sanded board moves to the movable bottom plate and covers the photoelectric sensor switch, the photoelectric sensor switch sends a signal to the translation motor, so that the movable bottom plate Move down, when the wooden board on the movable base leaves the working range of the photoelectric sensor switch, the translation motor stops moving, the second sanded board falls on the first sanded board, when the second sanded board When the wooden board blocks the photoelectric sensor switch again, the translation motor starts again and drives the movable bottom plate to move downward through the screw rod. When the second board leaves the working range of the photoelectric sensor switch, the translation motor stops moving and waits for the next sanded board; When the movable bottom plate triggers the limit switch at the bottom, the translation motor stops moving, and the sander also stops working. At this time, the worker manually starts the translation motor to drive the screw to drive the movable bottom plate to move upward to withstand the fixed bottom plate, and then manually starts the turning motor. The rotating sprocket on the rotating shaft cooperates with the chain on the outer surface of the arc-shaped overturning frame to drive the arc-shaped overturning frame to turn over. When the 匚-shaped material receiving platform of the arc-shaped overturning frame is in a horizontal position, the turning motor is stopped, and the plank is completed. The flipping operation makes the wooden board to be sanded face up, and then the flipped wooden board is moved to the entrance of the sanding machine by tools such as a forklift, and the sanding operation on the other side of the wooden board can be completed. The utility model has a simple structure, and compared with the existing production process, two board-receiving workers at the rear of the sanding machine are reduced, and at the same time, workers do not need to turn over each board one by one, thereby improving production efficiency.
