DETAILED DESCRIPTION

[0026] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0027] Example 1: An intelligent conveying device for producing plastic products, such as Figures 1-8 As shown, it includes a feed pipe 1, a screen drum 2, a rotary drive member 3 and a spiral blade 4; the feed pipe 1 has a discharge port at the upper end and an inlet at the lower end; a screen drum 2 is provided in the feed pipe 1, and the lower end opening of the screen drum 2 is communicated with the outside world; a spiral blade 4 is installed on the outer ring surface of the screen drum 2; a rotary drive member 3 is installed at one end of the feed pipe 1, and the rotary drive member 3 is a DD motor; the rotating end of the rotary drive member 3 is connected to the screen drum 2; it also includes a stirring rod 5; five pairs of vertically equidistantly distributed stirring rods 5 are provided on the outer ring surface of the screen drum 2; the stirring rod 5 is located in the feed path of the spiral blade 4.

[0028] It also includes a cylindrical rod 6, a connecting plate 7 and a spring telescopic rod 8; a cylindrical rod 6 is provided in the feed pipe 1, and the cylindrical rod 6 is located in the sieve cylinder 2; the outer ring surface of the cylindrical rod 6 is provided with three annular array convex strips 61; a connecting plate 7 is installed at one end of each stirring rod 5 located in the sieve cylinder 2; the stirring rod 5 passes through the cylinder wall of the sieve cylinder 2 horizontally; the side of the connecting plate 7 away from the stirring rod 5 is an arc surface; a spring telescopic rod 8 is connected between each connecting plate 7 and the inner wall of the sieve cylinder 2.

[0029] The outer annular surface of each stirring rod 5 is provided with a convex ring 9 .

[0030] In this embodiment, the feed pipe 1 is installed on an external bracket, and the plastic particles to be transported are fed into the feed pipe 1 through the lower end opening, and the screen drum 2 and the spiral blade 4 are driven to rotate by the rotating drive member 3, so that the plastic particles entering the feed pipe 1 are transported upward by the auger structure formed by the screen drum 2, the rotating drive member 3 and the spiral blade 4. The rotating drive member 3 is connected to the external intelligent control system to intelligently control the conveying speed. During the conveying process, the plastic particles are screened by the screen drum 2, and small plastic particles enter the screen drum 2 and are discharged outward from the lower end opening of the screen drum 2. At the same time, a stirring rod 5 is added to the screen drum 2, so that the stirring rod 5 rotates with the screen drum 2, and the rotational motion of the stirring rod 5 is used to stir and break up the plastic particles, which is more conducive to the screening and conveying of the plastic particles.

[0031] In addition, when the screen drum 2 and the stirring rod 5 rotate synchronously, the connecting plate 7 always moves on the surface of the cylindrical rod 6. When the connecting plate 7 moves over the convex strip 61 on the surface of the cylindrical rod 6, the spring telescopic rod 8 performs a telescopic action, and the stirring rod 5 slides back and forth on the wall of the screen drum 2, so that the stirring rod 5 synchronously drives the convex ring 9 to move back and forth, thereby utilizing the structure of the stirring rod 5 and the convex ring 9 to flip the plastic particles being transported laterally, further enhancing the effect of breaking up the plastic particles, and flipping the plastic particles at the same time, so that the position of the plastic particles changes continuously, thereby improving the screening efficiency of the plastic particles.

[0032] Example 2: Based on Example 1, Figures 1-8 As shown, a mesh plate 101 is installed on the inner wall of the conveying pipe 1; an air suction cavity 102 is formed between the inner wall of the conveying pipe 1 and the mesh plate 101; an air suction pipe 103 is installed through the side wall of the conveying pipe 1; and the air suction cavity 102 is connected to the air suction pipe 103.

[0033] The holes of the mesh plate 101 are smaller than the size of the plastic particles, so that the plastic particles will not fall out of the holes of the mesh plate 101 .

[0034] The stirring rod 5 is a hollow structure; one end of the stirring rod 5 is provided with a through hole 1 51 ; the other end of the stirring rod 5 is provided with a through hole 2 52 .

[0035] The outer ring surface of the stirring rod 5 is provided with two through grooves 53 ; the telescopic structure of the spring telescopic rod 8 has damping, so that the stirring rod 5 will not move back quickly.

[0036] The two through grooves 53 are distributed up and down, so that the through grooves 53 deviate from the rotation direction of the stirring rod 5, so that the through grooves 53 will not move directly towards the plastic particles, reducing the situation where the plastic particles are stuck in the through grooves 53 when the stirring rod 5 rotates to stir the plastic particles.

[0037] There are two protruding rings 9 on the stirring rod 5 , and the through groove 53 is located between the two protruding rings 9 .

[0038] In this embodiment, since the newly formed plastic particles have a certain temperature, they need to be cooled. However, in the prior art, heat exchange and cooling are generally performed outside the conveying structure. However, the plastic particles during transportation accumulate together, and the internal heat of the accumulated plastic particles cannot be quickly discharged, resulting in low heat dissipation efficiency. Therefore, in the present invention, the stirring rod 5 is designed to be a hollow structure to solve this problem.

[0039] First, the suction pipe 103 is connected to an external suction device, and a suction force is generated by the external suction device, so that the hot air from the plastic particles passes through the mesh plate 101 and is sucked away from the suction pipe 103 via the suction cavity 102. In addition, by designing the stirring rod 5 as a hollow structure, under the action of the suction force of the external suction device, air enters the stirring rod 5 from the through hole 1 51 and flows out from the through hole 2 52 to the position of the suction cavity 102, thereby forming a gas flow path inside the plastic particles, so that the hot air inside the plastic particles enters the stirring rod 5 from the through groove 53, and the lateral reciprocating movement of the stirring rod 5 is utilized to make the position of the through groove 53 move and change, thereby improving the suction effect of the hot air at various positions inside the plastic particles.

[0040] In addition, the through groove 53 is arranged between the two convex rings 9 so that the two convex rings 9 form an isolation effect on the opening of the through groove 53. That is, the distance between the two convex rings 9 is smaller than the size of the plastic particles, so that the plastic particles will not block the opening of the through groove 53, thereby improving the heat flow effect.

[0041] Example 3: Based on Example 2, Figures 1-8 As shown, it also includes a slide rod 10, a guide truncated cone 11, a cylindrical rod 2 12, a fixing plate 13, a connecting pipe 14, a fixing rod 15 and a telescopic drive member 16; the upper end of the slide rod 10 is installed on the inner top wall of the feeding pipe 1; the cylindrical rod 1 6 is divided into five equal parts vertically; each cylindrical rod 1 6 is equipped with a guide truncated cone 11 with a small upper part and a large lower part on the top; each guide truncated cone 11 is equipped with a cylindrical rod 2 12 on the top; the four cylindrical rods 2 12 at the bottom are respectively connected to the cylindrical rod 1 6 adjacent to the top; the diameter of the cylindrical rod 2 12 is smaller than that of the cylindrical rod 1 The cylindrical rod 16; all the cylindrical rods 16, the guide cone 11 and the cylindrical rod 2 12 slide on the sliding rod 10; the bottom end of the conveying pipe 1 is connected to a connecting pipe 14 through two fixing plates 13; the connecting pipe 14 passes through the screen cylinder 2; a fixing rod 15 is installed in the connecting pipe 14; the lower end of the sliding rod 10 is installed on the fixing rod 15; two telescopic driving members 16 are installed on the fixing rod 15, and the telescopic driving member 16 is an electric drive push rod; the telescopic ends of the two telescopic driving members 16 are commonly connected to the lowest cylindrical rod 16.

[0042] The bottom cylindrical rod 16 covers the two telescopic drive members 16 to block the falling plastic particles and reduce the plastic particles from falling onto the telescopic drive members 16.

[0043] In this embodiment, it is considered that once the conveying structure is blocked, workers need to manually take out the materials in the conveying structure or use other dredging methods. However, at this time, the materials in the conveying structure are relatively full, and it is difficult to dredge them, which may cause certain damage to the materials. Therefore, in the present invention, when a blockage occurs in the conveying pipe 1, the telescopic drive member 16 is controlled to drive the lowest cylindrical rod 16 to move downward, so that all cylindrical rods 16, the guide round table 11 and the cylindrical rod 2 12 slide downward on the slide bar 10, so that the cylindrical rod 16 moves away from the bottom. Open contact with the connecting plate 7. Since the diameter of the cylindrical rod 2 12 is smaller than that of the cylindrical rod 1 6, and the initial state of the spring telescopic rod 8 is a contracted state, the connecting plate 7 is gradually contacted with the cylindrical rod 2 12 under the guidance of the guide truncated cone 11 under the extension of the spring telescopic rod 8, thereby realizing the contraction of the stirring rod 5 into the screen drum 2, leaving the position originally occupied by the stirring rod 5 vacant. Under the action of the space reserved by the movement and contraction of multiple stirring rods 5, a residual space can be formed in the conveying pipe 1, allowing the plastic particles to loosen and collapse, thereby facilitating the dredging of the plastic particles.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
