Description

Technical Field

[0001] The present invention relates to the technical field of plastic waste recycling, and particularly relates to a waste plastic hot melt recycling device for preparing injection molding panels. Background Art

[0002] Injection molding panels are common plastic products widely used in fields such as electronic devices, household appliances, and automobiles. The plastic raw materials used for preparing injection molding panels need to have good fluidity to ensure uniform filling of the mold during the injection molding process, have a uniform particle size distribution to prevent product defects caused by uneven particle sizes, and also require extremely low impurity content to avoid affecting product properties such as transparency and strength. Therefore, when recycling waste plastics, a waste plastic hot melt recycling device for preparing injection molding panels is required;

[0003] For this reason, the patent with the authorization announcement number CN217226290U discloses a hot melt device for recycling waste plastics, including a device main body. Above the inside of the device main body, a screening frame is fixed. A screen is installed around the outer surface of the screening frame. A screen material component is arranged at the bottom of the screening frame. Cylinders are installed on both sides of the screening frame. The output end of the cylinder is connected to a piston rod, and a pressing material component is arranged at the bottom of the piston rod. In this device, through the setting of the screen material component, when the plastic is crushed by the blade, the fan blows air upwards, so that the falling plastic will be blown, and the plastic will move along the guiding frame towards the blade direction. The plastics with small particle sizes can be screened through the screen, and the plastics with large particle sizes will continue to be cut by the blade under the influence of the wind until they reach the particle size suitable for screening by the screen, making the plastic crushing more comprehensive and avoiding the situation that large particle plastics sink to the bottom and cannot be further crushed, resulting in omissions in plastic processing;

[0004] The above-mentioned hot melt device for recycling waste plastics inputs waste plastics into the inside of the device main body through the feed port, and then drives the blade to crush the plastics through the motor. After screening, it is subjected to hot melt treatment. However, during the hot melt process, it is inconvenient to stir the waste plastics, resulting in insufficient contact between the plastics and heat during the melting process, slow melting speed, and affecting work efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a waste plastic hot melt recycling device for preparing injection molding panels to solve the defect of insufficient melting and stirring of the existing waste plastic hot melt recycling device for preparing injection molding panels.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A waste plastic hot melt recycling device for preparing injection molding panels, including a heating tank;

[0007] One side of the bottom of the heating tank is fixedly provided with a discharge port. A cover body is arranged at the top end of the heating tank. A protective structure is fixedly installed at the bottom end of the cover body. The protective structure includes a rotating plate arranged inside the cover body. A pressure bearing is arranged at the bottom end of the rotating plate. A support seat is arranged at the bottom end of the pressure bearing;

[0008] One side of the top of the heating tank is fixedly provided with a hopper. An impurity removal structure is arranged on one side of the top of the hopper;

[0009] A stirring structure is arranged inside the heating tank. The stirring structure includes a main stirring shaft arranged at the middle position inside the heating tank. First secondary stirring shafts are arranged on both the left and right sides of the main stirring shaft. Second secondary stirring shafts are arranged on both the front and back sides of the main stirring shaft. The top end of the main stirring shaft passes through the rotating plate and is fixed with a driving gear. The top ends of the first secondary stirring shafts and the second secondary stirring shafts both pass through the rotating plate and are fixed with transmission gears.

[0010] Preferably, a driving motor is fixedly installed at the middle position of the top end of the cover body. Tooth grooves are evenly formed on the inner wall of the top of the cover body.

[0011] Preferably, the output end of the driving motor extends to the inside of the cover body and is fixedly connected to the top end of the driving gear.

[0012] Preferably, a baffle is installed at the neck of the hopper. The hopper and the baffle are slidably connected.

[0013] Preferably, the impurity removal structure includes a clamping groove, a fixed frame, a magnet, a micro motor, a belt roller, a conveyor belt and a blanking frame. The clamping groove is formed on one side inside the hopper. The fixed frame is arranged inside the clamping groove. One end of the fixed frame extends to the outside of the hopper. A blanking frame is fixedly arranged on the outer wall of the hopper below the fixed frame. Belt rollers are rotatably connected to both sides inside the fixed frame. Conveyor belts are arranged on the outer sides of the belt rollers. A magnet is fixedly arranged on one side inside the fixed frame close to the hopper. A micro motor is fixedly installed on one side of the top end of the fixed frame away from the hopper.

[0014] Preferably, the fixed frame and the hopper are clamped with each other through the clamping groove. One end of the magnet is located outside the hopper. The output end of the micro motor is fixedly connected to one end of the belt roller. The inner side wall of the conveyor belt is in contact with the outer side wall of the magnet.

[0015] Preferably, the support seat is in a stepped ring shape. The support seat and the cover body are fixedly connected by bolts. The support seat and the rotating plate form a rotating structure through the pressure bearing.

[0016] Preferably, the outer wall of the main stirring shaft is uniformly fixed with first stirring rods, the outer walls of the first auxiliary stirring shafts are all fixed with second stirring rods, and the outer walls of the second auxiliary stirring shafts are all fixed with spiral blades.

[0017] Preferably, the transmission gears are equally spaced outside the driving gear, the driving gear and the transmission gears are meshed, and the transmission gears and the cover body are meshed through tooth grooves.

[0018] Preferably, the first stirring rods and the second stirring rods are distributed alternately.

[0019] The waste plastic hot melt recycling device for preparing an injection molding panel provided by the present invention has the following advantages:

[0020] By providing a stirring structure, the driving gear and the transmission gears are meshed, so that the first auxiliary stirring shaft and the second auxiliary stirring shaft both rotate in the opposite direction to the main stirring shaft. The first stirring rods and the second stirring rods are distributed alternately, so that the second stirring rods can stir the plastic between the first stirring rods, and the moving directions of the second stirring rods and the first stirring rods are opposite, which can stir the plastic more evenly;

[0021] Furthermore, when the spiral blades rotate, they will drive the plastic to move upward, moving the plastic at the bottom to the top, turning the plastic, and enhancing the uniformity of stirring;

[0022] Furthermore, under the meshing action of the transmission gears and the tooth grooves, the first auxiliary stirring shaft and the second auxiliary stirring shaft rotate around the main stirring shaft while rotating on their own axes. Thus, the first auxiliary stirring shaft and the second auxiliary stirring shaft move inside the heating tank, so that the plastic inside the heating tank can be turned up and down while being stirred, improving the stirring efficiency, enabling the plastic to contact heat more fully during the melting process, accelerating the melting speed, and thus improving the working efficiency of the device during use;

[0023] By providing a protection structure, the support seat supports the rotating plate inside the cover body through a pressure bearing. Under the shielding action of the support seat and the rotating plate, it is avoided that the plastic splashes into the inside of the cover body during the stirring process;

[0024] Furthermore, while the transmission gears drive the first auxiliary stirring shaft and the second auxiliary stirring shaft to rotate on their own axes, the first auxiliary stirring shaft and the second auxiliary stirring shaft will drive the rotating plate to rotate inside the cover body. The friction between the rotating plate and the support seat is reduced through the pressure bearing, thereby extending the service life of the device;

[0025] By setting up a impurity removal structure, after the waste plastics are crushed, they are added into the interior of the heating tank through a hopper. During the process of the plastics passing through the hopper, a micro-motor drives a conveyor belt to rotate outside a magnet through a belt roller. Under the magnetic force of the magnet, the metal particles in the waste plastics will be adsorbed on the outer wall of the conveyor belt. The rotation of the conveyor belt will transport the metal particles to the outside of the hopper, and when the metal particles move out of the adsorption range of the magnet, they will automatically fall off, realizing the function of impurity removal of the device, thereby improving the product quality of the injection panel.
