[0009] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0010] Embodiment 1: An automatic trimming device for pine plywood, such as Figure 1-Figure 2As shown, it includes a base frame, a base plate, a grinding roller, a fixed plate, a slide groove, an electric slider, a bracket, a spring, an electromagnet, a magnet, a fixed rod, a hollow plate, a fan, an air outlet frame and an air outlet duct. Two base plates are welded on the upper part of the base frame, and the two base plates are symmetrically arranged. A plurality of grinding rollers are rotatably connected to the upper parts of the two base plates. A plurality of grinding rollers located on the same base plate form a group. The plurality of grinding rollers are used for trimming pine plywood. A fixed plate is rotatably connected to the upper parts of a plurality of grinding rollers in each group. Two slide grooves are opened on one side of the upper part of the base frame. The two slide grooves are symmetrically arranged. Electric sliders are slidably connected in the two slide grooves. The upper parts of the two electric sliders are connected to the brackets by bolts. The upper parts of the two brackets are connected by hooks. A spring is connected, and the other ends of the two springs are connected to an electromagnet through a hook. The electromagnet is slidably connected to the bracket, and the upper parts of the two electric sliders are connected to magnetic plates through rivets. The electromagnet box magnetic plate is used to press the loose plywood. Four fixing rods are welded to the upper part of the base frame, and a hollow plate is connected between the upper parts of the four fixing rods by bolts. A fan is welded to the upper part of the hollow plate, and the air outlet of the fan is connected to the inside of the hollow plate. The bottom of the hollow plate is connected to an air outlet frame by rivets, and the air outlet frame is connected to the inside of the hollow plate.

A plurality of air outlet pipes are connected to the two inclined surfaces of the air outlet frame through flanges, and a plurality of air outlet pipes located on the same inclined surface of the air outlet frame form a group.

[0011] First, the pine plywood that needs to be trimmed is placed on the base frame manually, and then the two electromagnets are started manually, and the pine plywood contacts with the two magnetic plates. When the electromagnet is energized, the magnetism of the electromagnet is opposite to that of the magnetic plates, and the electromagnet will attract the magnetic plates, so that the pine plywood is pressed tightly. Then the two electric sliders and the fan are started manually, and the two electric sliders drive the two magnetic plates, two brackets, two springs, two electromagnets and the pine plywood to move. The pine plywood contacts with both sets of grinding rollers, and the two sets of grinding rollers will trim both sides of the pine plywood. The wind blown out by the fan will enter the air outlet frame, and then blown out by the two sets of air outlet ducts. The wind blown out by the fan will blow away the debris generated when the pine plywood is trimmed. Then the two electric sliders drive the two magnetic plates, two brackets, two springs, two electromagnets and the pine plywood. The plate moves in the opposite direction, and the two sets of grinding rollers trim the loose plywood again, and then the two electric sliders and the two electromagnets are manually closed, the two electromagnets are no longer energized, the electromagnets no longer attract the magnetic plate, and the loose plywood is no longer pressed. At this time, the trimmed loose plywood is manually removed and the pine plywood that needs to be trimmed is replaced. At the same time, the two springs will adapt to pine plywood of different thicknesses, and so on and so forth, and the two sides of the pine plywood can be trimmed multiple times, so that the trimming of both sides of the pine plywood is more sufficient, thereby making the trimming effect of the pine plywood better, and at the same time, the debris generated during the trimming can be blown away to avoid the debris from interfering with the trimming work of the pine plywood as much as possible. In addition, it can also adapt to pine plywood of different thicknesses, making the device more versatile.
