[0002] The continuous drying equipment for plastic production is a kind of equipment specially used for drying plastic particles. It uses the principle of hot air circulation, heater and fan to send hot air into the hopper, so that the plastic particles are heated evenly and the moisture is quickly removed. The equipment has the characteristics of efficient drying, intelligent control, energy saving and environmental protection, and easy maintenance. It is widely used in plastic processing fields such as injection molding, extrusion molding, blow molding, etc. It can improve the quality of plastic products, reduce defects, and improve production efficiency.

[0003] The plastic pellet drying process usually consists of a conveyor belt and a heating component.

[0040] Example 2: Please refer to Figures 1 to 4 The present invention provides a technical solution: a continuous drying device suitable for plastic production. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The auxiliary mechanism 2 also includes a vibration unit 22, which is arranged on one side of the conveying component 11. The vibration unit 22 is used to vibrate the plastic particles being dried.

[0041] As a further limitation of the auxiliary mechanism 2 of the present invention, the vibration unit 22 includes a first transmission wheel 2201, the first transmission wheel 2201 is fixedly mounted on the surface of the rotating rod 2103, the inner wall of the transmission assembly 11 is rotatably connected with a driven rod 2204, the number of driven rods 2204 is several, one end of one driven rod 2204 is fixedly mounted with a second transmission wheel 2202, the surface of the first transmission wheel 2201 is movably sleeved with a transmission belt 2203, the first transmission wheel 2201 and the second transmission wheel 2202 are transmission-connected through the transmission belt 2203, and a knocking ring 2207 is fixedly mounted on the surface of the driven rod 2204. There are several knocking rings 2207, a first gear 2205 is fixedly mounted on the surface of the driven rod 2204, a second gear 2206 is rotatably connected to the inner wall of the transmission component 11, two adjacent first gears 2205 are meshed with each other through the second gear 2206, and the vibration unit 22 is provided to vibrate the plastic particles entering the heating component 12, thereby increasing the contact area between the plastic particles and the hot air, so that the plastic particles are heated more evenly, thereby improving the heating effect of the plastic particles, making the plastic particles better dried, and at the same time reducing the drying time of the plastic particles, thereby increasing the work efficiency;

[0042] The surface of the knocking ring 2207 is provided with a fixed groove 2208, the inner cavity of the fixed groove 2208 is provided with a spring 2210, the inner cavity of the fixed groove 2208 is slidably connected with a knocking block 2209, one end of the spring 2210 is fixedly connected to the inner wall of the fixed groove 2208, and the other end of the spring 2210 is fixedly connected to the surface of the knocking block 2209.

During the rotation of the driven rod 2204, through the engagement of the first gear 2205 and the second gear 2206, multiple driven rods 2204 can be rotated in the same direction, thereby driving the knocking ring 2207 to knock the bottom of the upper surface of the conveyor belt in the conveying component 11, so that the plastic particles entering the heating component 12 are vibrated, thereby increasing the heating area of ​​the plastic particles, further accelerating the drying speed of the plastic particles, and at the same time making the plastic particles more fully dried, further improving the work efficiency.

[0045] Example 3: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The present invention provides a technical solution: a continuous drying device suitable for plastic production. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A preheating mechanism 3 is provided on one side of the heating component 12. The preheating mechanism 3 is used to preheat the flattened plastic particles. The preheating mechanism 3 is used in conjunction with the flattening unit 21.

[0046] As a further limitation of the present invention, the preheating mechanism 3 includes an insulation hose 301, which is fixedly connected to one side of the heating component 12, and an air pump 302 is fixedly installed on the top of the push plate 2107. One end of the insulation hose 301 is fixedly connected to the input end of the air pump 302, and the output end of the air pump 302 is fixedly connected to an air inlet pipe 303. The inner wall of the push plate 2107 is fixedly installed with an air distribution pipe 304, and the surface of the air distribution pipe 304 is fixedly connected to an air outlet pipe 305. The number of the air outlet pipes 305 is several, and one end of the air inlet pipe 303 is fixedly connected to the surface of the air distribution pipe 304.

[0049] S1: Placing plastic particles on the top of the conveying component 11, conveying the plastic particles through the conveying component 11, and starting the motor 2102 at the same time, driving the half gear 2104 to rotate through the motor 2102, so that the push plate 2107 can move, and through the cooperation with the tension spring 2108, the push plate 2107 can reciprocate, so as to achieve the flattening of the plastic particles before entering the heating component 12;

[0050] S2: After the conveying component 11 conveys the plastic particles to the interior of the heated plastic part, the heating component 12 dries the plastic particles. Meanwhile, during the rotation of the motor 2102, the first transmission wheel 2201 and the second transmission wheel 2202 are connected by the transmission belt 2203, so that the driven rod 2204 can rotate. By knocking the conveying component 11 with the knocking ring 2207, the particles entering the heating component 12 can be slightly jumped, thereby increasing the heating effect of the plastic particles.

[0051] S3: Before the plastic particles enter the heating component 12, the heating component 12 is turned on in advance, and the hot air generated by the heating component 12 is partially transported to the air distribution pipe 304 through the insulation hose 301, and the hot air is blown to the surface of the plastic particles that have not entered the heating component 12 through the air outlet pipe 305, so as to preheat the plastic particles and reduce the drying time of the plastic particles.

10. A drying method for continuous drying equipment suitable for plastic production, characterized in that: The following steps are involved: S1: Placing plastic particles on top of the conveying component (11), conveying the plastic particles through the conveying component (11), and starting the motor (2102) at the same time, driving the half gear (2104) to rotate through the motor (2102), so that the push plate (2107) can be moved, and through the cooperation with the tension spring (2108), the push plate (2107) can be reciprocated to achieve the flattening of the plastic particles before entering the heating component (12); S2: After the conveying component (11) conveys the plastic particles to the interior of the heated plastic part, the heating component (12) dries the plastic particles. At the same time, during the rotation of the motor (2102), the first transmission wheel (2201) and the second transmission wheel (2202) are connected by a transmission belt (2203), so that the driven rod (2204) can rotate. By knocking the conveying component (11) with the knocking ring (2207), the particles entering the heating component (12) can be slightly bounced, thereby increasing the heating effect of the plastic particles. S3: Before the plastic particles enter the heating component (12), the heating component (12) is turned on in advance, and part of the hot air generated by the heating component (12) is transported to the air distribution pipe (304) through the heat-insulating hose (301), and the hot air is blown to the surface of the plastic particles that have not entered the heating component (12) through the air outlet pipe (305), so as to preheat the plastic particles and reduce the drying time of the plastic particles.
