Description

Technical Field

[0001] This utility model relates to the field of wood-plastic crusher technology, and in particular to a crusher for PE wood-plastic. Background Technology

[0002] Most PE wood-plastic crushers on the market currently use a blade-type structure, employing V-shaped blades with fixed and moving blades. The rotor rotates to drive the moving and fixed blades to shear and crush waste plastics.

[0003] The crushers on the market use conventional crushers with V-shaped moving blades. The blades are made of special materials. The V-shaped moving blades and fixed blades shear and crush materials. This structure can crush ordinary, tough plastics without any problems.

[0004] However, PE wood-plastic composites have a high wood powder content and a low plastic content, and the waste materials are very hard. Traditional crusher blades are very efficient when new, but after less than a day of use, the blades become dull, causing a significant reduction in output. Frequent sharpening of the blades is required, consuming a lot of manual labor, and the blades need to be replaced quickly, resulting in high operating costs. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the structure of the V-shaped moving blade and fixed blade used in the crusher in the prior art is prone to severe blade wear, frequent blade replacement, which not only increases working time, but also shortens the life of the blade and requires a certain amount of money to buy new blades.

[0006] To solve the above-mentioned technical problems, this utility model provides a PE wood-plastic composite crusher, comprising: a base frame; an intermediate box mounted on the base frame, wherein the intermediate box is provided with a feeding channel for feeding wood-plastic composite boards; an upper box mounted on the intermediate box, wherein the inner boxes of the upper box and the intermediate box are connected to form a crushing chamber, and the feeding channel is connected to the crushing chamber; a main motor serving as a power element; a belt pulley transmission assembly connected to the main motor; and a blade assembly connected to the main motor via the belt pulley transmission assembly, wherein the main motor drives the blades on the blade assembly to rotate and crush the wood-plastic composite boards. Since PE wood-plastic waste contains 60% wood flour, 10% calcium powder, and less than 30% PE plastic, the material is very hard. A swivel blade structure is used, with blades made of specially treated steel plates. An electric motor drives the rotor to rotate, and multiple blades rotate at high speed in one revolution to achieve the desired PE wood-plastic crushing effect. This ensures good hardness and stable output during use. A new set of blades is only needed every few months, significantly reducing operating costs by saving time on blade replacements.

[0007] In one embodiment of this utility model, the swivel blade assembly includes several blades, a blade fixing rod, an end blade seat, an intermediate blade seat, and a rotating shaft. Two end blade seats are provided, and the two end blade seats are respectively disposed on both sides of the intermediate blade seat. The end blade seats and the intermediate blade seats are connected as a whole by the blade fixing rod. Both the end blade seats and the intermediate blade seats are provided with blades. The rotating shaft is connected to the two end blade seats and drives the end blade seats and the intermediate blade seats to rotate. One end of the rotating shaft is connected to a belt pulley transmission assembly.

[0008] In one embodiment of this utility model, a blade holder is provided between the end blade holder and the intermediate blade holder, and between adjacent intermediate blade holders.

[0009] In one embodiment of this utility model, the intermediate housing is provided with two rotor support seats, and the two ends of the rotating shaft are respectively disposed on the two rotor support seats, the two rotor support seats being used to support the rotation of the rotating shaft.

[0010] In one embodiment of this utility model, the rotor support includes a pressure cap, a skeleton oil seal, a bearing, and a bearing housing. The bearing housing is fixed on the intermediate housing, the bearing is disposed on the bearing housing, and the rotating shaft is disposed in the inner ring of the bearing. The skeleton oil seal is used to seal the connection position between the bearing and the rotating shaft. The pressure cap is connected to the bearing housing, and the pressure cap is used to lock the skeleton oil seal.

[0011] In one embodiment of this utility model, an inertia wheel is provided at the other end of the rotating shaft away from the belt pulley transmission assembly.

[0012] In one embodiment of the present invention, the belt pulley transmission assembly includes a transmission belt, a driven pulley, and a driving pulley. The driving pulley is connected to the shaft of the main motor, the driving pulley is connected to the driven pulley via the transmission belt, and the driven pulley is connected to one end of the shaft via a key.

[0013] In one embodiment of this utility model, the base frame is provided with a pulley support seat, the pulley support seat is provided with a belt cover, and the belt cover covers the transmission belt.

[0014] In one embodiment of this utility model, the base frame is provided with a receiving hopper, which is connected to the crushing chamber and is used to receive crushed wood-plastic composite board particles.

[0015] In one embodiment of the present invention, an air inlet is installed on the feeding channel, the air inlet is connected to the feeding channel and the crushing chamber, and the air inlet is used to provide airflow to blow the particles in the crushing chamber out.

[0016] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects: The PE wood-plastic composite crusher of this utility model adopts a swing blade structure. The blades are made of steel plate with special material treatment. The material enters directly and is crushed by the high-speed rotation of the swing blade. After being crushed, the material is filtered through a screen. The distance between the screen and the end of the swing blade is about 10 mm. The screen can be removed and installed by screws by replacing the outer side of the screen. After crushing, large particles are further crushed into smaller particles by the rotor driving the blade. The air inlet adopts a mesh structure to ensure that the material does not fly out of the feed port when air is introduced. The structure is simple and the later use and maintenance costs are low.
