DETAILED DESCRIPTION

[0017] The specific embodiment of the utility model is further explained below in combination with the drawings.

[0018] As Figures 1-5The utility model discloses a raw material drying device for wood plastic composite material, including support seat 1, be provided with electric heating module 2 on support seat 1, be provided with annular drying groove 3 on electric heating module 2, the lower surface of drying groove 3 is provided with the discharge gate, and the lower surface of drying groove 3 and located the both sides of discharge gate are provided with baffle 4, and the door plate 5 for closing discharge gate is set up between two baffle 4, and one end of door plate 5 is rotatably connected with two baffle 4, and the mounting bracket 6 is set up below two baffle 4, still including electric push rod 7, the base of electric push rod 7 is rotatably connected with mounting bracket 6, and the telescopic end of electric push rod 7 is rotatably connected with door plate 5, still including placing table 8, be provided with motor 9 on placing table 8, and the output of motor 9 is provided with the cover 10 for shielding drying groove 3, and the upper surface of cover 10 is opened with the blanking head, and the blanking head of cover 10 is provided with hopper 11, and the outer surface of cover 10 is provided with exhaust hole, and the lower surface of cover 10 is evenly provided with a plurality of pusher units, and the pusher unit includes two guide blocks 12, and the horizontal rod 13 is set up between two guide blocks 12, and a plurality of turnover plates 14 are set up at the interval on horizontal rod 13, and the lower end of turnover plate 14 is in contact with the bottom of drying groove 3, and the turnover plate 14 of adjacent two pusher units is set up in staggered.

[0019] When drying wood filler, first, a proper amount of wood filler is put into the hopper 11, then the electric heating module 2 is started to heat the drying groove 3, and at the same time, the motor 9 is started, and the output end of the motor 9 drives the cover 10 to rotate, and in the process of rotating, the cover 10 drives the hopper 11 to rotate, and there is a height difference between the lower end of the hopper 11 and the inner bottom surface of the drying groove 3, so that the wood filler in the hopper 11 can fall into the inside of the drying groove 3, and when all the wood filler in the hopper 11 enters the drying groove 3, the volume of the wood filler in the drying groove 3 accounts for about half of the total volume of the drying groove 3, so as to leave space for the turning of the wood filler, and when the cover 10 rotates, it also drives the guide blocks 12 and the turnover plates 14 below the cover 10 to rotate, and the guide blocks 12 and the turnover plates 14 continuously turn the wood filler in the drying groove 3, so that the inner layer and the outer layer of the wood filler can be circulated alternately, and the movement tracks of the turnover plates 14 in the adjacent two pusher units do not completely coincide, and there is a certain overlapping area between them, so as to avoid the turning blind area affecting the drying of the wood filler, and the steam generated during drying is discharged through the exhaust hole.

[0020] When the wood filler in the drying tank 3 is dried, the wood filler in the drying tank 3 needs to be taken out, specifically, the electric heating module 2 is closed, and then the electric push rod 7 is started, the telescopic end of the electric push rod 7 drives the door plate 5 to overturn, so that the discharge port of the drying tank 3 is in an open state, then the motor 9 is controlled to rotate reversely, when the motor 9 rotates reversely, the wood filler in the drying tank 3 is moved through the turning plate 14 and the guide block 12, when the wood filler passes through the discharge port, the wood filler is discharged from the discharge port of the drying tank 3, and the staff can collect it. Since the turning plate 14 below the cover 10 is arranged in a staggered manner, and the movement tracks of the turning plates 14 in the adjacent pushing units also overlap, and the guide blocks 12 on both sides, the wood filler in the drying tank 3 can be effectively pushed to the discharge port.

[0021] When the output end of the motor 9 rotates forwardly, the guide block 12 and the turning plate 14 mainly play a role of turning and stirring the wood filler in the drying tank 3, and the movement of the guide block 12 and the turning plate 14 only drives a small amount of wood filler to move with them, and when the output end of the motor 9 rotates reversely, the movement of the guide block 12 and the turning plate 14 drives more wood filler to continuously move with them, at this time, the guide block 12 and the turning plate 14 mainly play a role of pushing the wood filler.

[0022] The electric heating module 2 is electromagnetic heating, and the temperature of heating is controlled by a temperature sensor, a controller and an actuator.

[0023] The length of the door plate 5 is greater than the length of the discharge port, so that the wood filler in the drying tank 3 can slide downward along the door plate 5 under the condition that the door plate 5 can close the discharge port.

[0024] Further, the lower end of the hopper 11 extends into the inside of the drying tank 3, which can reduce the thickness of the wood filler when it falls in the drying tank 3 for the first time, and facilitate the efficiency of the turning plate 14 and the guide block 12 to evenly spread the wood filler in the drying tank 3.

[0025] Further, the guide block 12 and the turning plate 14 have a guide surface and a pushing surface, when the wood filler in the drying tank 3 is turned and stirred, the guide surface on the guide block 12 and the turning plate 14 is in surface contact with the wood filler, the guide surface on the guide block 12 is used to push the wood filler close to the side wall of the drying tank 3 to the middle of the drying tank 3, and the guide surface on the turning plate 14 is used to turn the wood filler layer, when the wood filler in the drying tank 3 needs to be discharged, the pushing surface on the guide block 12 and the turning plate 14 is in surface contact with the wood filler, which can effectively intercept and push the wood filler to move, so as to push the wood filler to the position of the discharge port of the drying tank 3.

[0026] Further, the material turning plate 14 is made of metal material, when the drying groove 3 is heated, the heat can be transmitted to the material turning plate 14, so that the material turning plate 14 is heated, and the wood filler is heated by the temperature of the material turning plate 14 in the process of turning and stirring, so that the wood filler is heated while being turned and stirred.

[0027] Further, the upper end of the exhaust hole is provided with the extension cylinder 15, so that the wood filler in the drying groove 3 is prevented from overflowing from the exhaust hole.

[0028] In the description of the utility model, unless another definite provision and limitation, the term "installation", "link", "connection" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can indirectly be connected through intermediate medium, can be two elements inside the communication, for the ordinary skilled in the art, the above-mentioned term can be understood according to the specific meaning in the utility model.
