[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-4 The utility model provides a technical solution: a plastic uniform drying box, including a box body 1, a bracket 2, a rotating shaft 3, a conveyor belt 4, a bump 5, a feed hopper 6, a discharge hopper 7, a heating plate 8, a motor 9, a fan 10, an exhaust pipe 11, an impeller 12, an eccentric wheel 13, a push rod 14, a baffle 15, and a spring 16.
[0025] This device has the effect of uniformly drying plastics, specifically:
[0026] Multiple groups of brackets 2 are fixed inside the box 1. A rotating shaft 3 is installed on one side of the bracket 2, and the other end of the rotating shaft 3 is installed on another bracket 2. A heating plate 8 is arranged on the inner wall of one side of the box 1. An air inlet is arranged below the box 1. The bracket 2 is installed at the air inlet below the box 1, and a motor 9 is arranged on the bracket 2 there. A fan 10 is connected to the output end of the motor 9. Multiple groups of conveyor belts 4 are arranged, and the cross section of the conveyor belts 4 is an inclined structure. The end of the upper conveyor belt 4 is aligned with the head end of the lower conveyor belt 4. The lower end of the feed hopper 6 is aligned with the head end of the uppermost conveyor belt 4, and the discharge hopper 7 is aligned with the tail end of the lowermost conveyor belt 4. The brackets 2 at the conveyor belt 4 are multiple groups of parallel longitudinal brackets 2. The cross section of the bracket 2 at the motor 9 is a cross. The heating plate 8 and the conveyor belt 4 are separated by a plate inside the box 1, and a plurality of ventilation holes aligned with the conveyor belt 4 are arranged on the plate.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the plastic to be dried is placed in the feed hopper 6, and the heating plate 8 and the motor 9 are started. The heating plate 8 heats the air in the device, and the motor 9 drives the fan 10 to rotate. The rotation of the fan 10 continuously sucks the air outside the device into the device from the air inlet below. The conveyor belt 4 on the rotating shaft 3 is started, and the conveyor belt 4 starts to rotate. The plastic falls from the lower end of the feed hopper 6 onto the conveyor belt 4 and moves with the conveyor belt 4. When it moves to the end of the conveyor belt 4, the plastic will fall into the conveyor belt 4 below, until the plastic falls into the discharge hopper 7 below the box 1 driven by the conveyor belt 4 and is sent out of the device. While the plastic is transmitted on the surface of the conveyor belt 4, the air heated by the heating plate 8 is transported to the surface of the conveyor belt 4 from the ventilation holes on one side of the conveyor belt 4, and the plastic on the surface of the conveyor belt 4 is dried with hot air and discharged from the exhaust pipe 11 above the device.
[0028] This device has the effect of intermittent feeding and uniform spreading, specifically:
[0029] A conveyor belt 4 is provided on the outer surface of the rotating shaft 3, and a protrusion 5 is provided on the surface of the conveyor belt 4. A feed hopper 6 is provided above the box body 1, and the lower end of the feed hopper 6 passes through the surface of the box body 1. A discharge hopper 7 is provided below the box body 1, and the discharge hopper 7 passes through the surface of the box body 1. An exhaust pipe 11 is provided above one side of the box body 1, and an impeller 12 is provided inside the exhaust pipe 11. An eccentric wheel 13 is provided on one side of the impeller 12, and the impeller 12 and the eccentric wheel 13 are connected by a belt. A push rod 14 is provided on one side of the eccentric wheel 13, and the other end of the push rod 14 is connected to a baffle 15, and the push rod 14 passes through the upper surface of the box body 1. The push rod 14 is connected to a spring 16, and the other end of the spring 16 is connected to the exhaust pipe 11. The push rod 14 is slidably connected to the upper surface of the box body 1, and the area of the baffle 15 connected to one end of the push rod 14 is larger than the area of the lower end of the feed hopper 6.
[0030] like Figure 1-Figure 4 As shown, the surface of the conveyor belt 4 is provided with equidistant protrusions 5. After the device is started, hot air enters the exhaust pipe 11, driving the impeller 12 to rotate clockwise. The rotation of the impeller 12 drives the eccentric wheel 13 to rotate. When the eccentric wheel 13 rotates, it pushes the push rod 14 to move outward. The push rod 14 squeezes the spring 16. The spring 16 is compressed. The push rod 14 moves outward and drives the baffle 15 to move outward. At this time, the lower end of the feed hopper 6 is exposed, and the plastic falls from the feed hopper 6 onto the conveyor belt 4. Since the surface of the conveyor belt 4 is provided with protrusions 5, The plastic that falls into the conveyor belt 4 will be separated by the protrusions 5 and evenly distributed on the surface of the conveyor belt 4. When the push rod 14 loses the thrust of the eccentric wheel 13, the spring 16 returns to its original state, driving the push rod 14 to return to its original state. The push rod 14 drives the baffle 15 to block the bottom of the feed hopper 6 again, so that the plastic in the feed hopper 6 is no longer transported into the device. The continuous rotation of the eccentric wheel 13 causes the bottom of the feed hopper 6 to be intermittently closed and opened, so that the plastic is intermittently transported into the device, preventing the plastic from accumulating on the surface of the conveyor belt 4 and affecting the drying efficiency.
[0031] Working principle: When using the plastic uniform drying box, start the conveyor belt 4, the heating plate 8 and the motor 9, the motor 9 drives the fan 10 to rotate, the fan 10 and the heating plate 8 work together to continuously deliver hot air to the surface of the conveyor belt 4 through the vents to dry the plastic on the surface of the conveyor belt 4, and when the hot air reaches the exhaust pipe 11, it drives the impeller 12 to rotate, and the impeller 12 drives the eccentric wheel 13 to rotate, and the eccentric wheel 13 continuously applies pressure to the push rod 14. Under the action of the spring 16 and the push rod 14, the baffle 15 under the feed hopper 6 is continuously closed and opened, so that the plastic in the feed hopper 6 is intermittently transported into the device. Because the surface of the conveyor belt 4 is equidistantly provided with protrusions 5, under the joint action of the protrusions 5 and the baffle 15, the plastic is evenly distributed on the surface of the conveyor belt 4, preventing the plastic from accumulating on the surface of the conveyor belt 4, affecting the drying efficiency, and increasing the overall practicality.
[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
