Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, and particularly relates to a plastic particle stirring device. Background Art

[0002] Plastic particles, commonly known as plastic pellets, are raw materials for storing, transporting, and processing plastics in semi-finished form. During the plastic processing process, it is necessary to remove the moisture in the plastic particles to improve the efficiency and quality of the plastic processing process. At the same time, the plastic particles need to be continuously mixed and stirred to prevent the plastic particles from sticking together during the moisture removal process.

[0003] There are some existing stirring devices. For example, a utility model patent document with the authorization announcement number of "CN219190812U" and the patent name of "A Plastic Particle Stirring Device" discloses a plastic particle stirring device. The stirring device includes a tank body, a first motor, a stirring frame, stirring rods, and a discharge port.

[0004] When plastic particles need to be stirred and processed, the plastic particles are placed inside the tank body. Subsequently, the first motor is started, and the materials in the tank body are double-axis stirred through the stirring frame and the stirring rods. Then, the stirred plastic particles are discharged and collected through the discharge port. However, when some existing stirring devices discharge materials, a large number of plastic particles gather at the discharge port at the same time, and there may still be moisture in the plastic particles, which easily causes the plastic particles to stick together at the discharge port, resulting in a blockage phenomenon and being unfavorable for the discharge of plastic particles. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a plastic particle stirring device to solve the technical problem that some existing plastic particle stirring devices are prone to blockage during discharging, which is unfavorable for the discharge of plastic particles mentioned in the background art.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A plastic particle stirring device includes a stirring barrel. The top and bottom of the stirring barrel are respectively provided with a feed port and a discharge port. A stirring assembly for stirring and drying plastic particles is arranged inside the stirring barrel. A discharge assembly for preventing blockage of the discharge port is arranged below the stirring assembly. Two knocking rods are arranged on the discharge assembly, and the two knocking rods are used to shake off the plastic particles accumulated on the bottom side wall of the stirring barrel.

[0008] Working Principle:

[0009] First, the operator starts the stirring component and the discharging component respectively, then pours the plastic particles into the stirring barrel, so that the plastic particles are first mixed and stirred by the stirring component, and then discharged from the discharging port through the discharging component. At the same time, the two knocking rods knock on the stirring barrel along with the discharging component to shake off the plastic particles adhering to the bottom side wall of the stirring barrel.

[0010] The beneficial effects of the present utility model are as follows:

[0011] During the use of the present utility model, the operator enables the plastic particles to pass through the stirring component and the discharging component successively, so as to mix and stir the plastic particles, enabling the plastic particles to contact with air and separate from each other, avoiding the retention of plastic particles in the stirring barrel, and making the discharging effect of the plastic particles better.

[0016] During the use of the present utility model, the operator enables the plastic particles to pass through the stirring component and the discharging component successively, so as to mix and stir the plastic particles, enabling the plastic particles to contact with air and separate from each other, avoiding the retention of plastic particles in the stirring barrel 1, and making the discharging effect of the plastic particles better.

The first bevel gear 9 drives the rotating rod 8, the positioning cylinder 13 and the stirring shaft 34 to rotate through the second bevel gear 10 meshing with it. The positioning cylinder 13 pushes the knocking rod 4 through the spring 14 inside it to abut against the inner wall of the stirring barrel 1. When the knocking rod 4 rotates into the arc-shaped groove 15, the spring 14 pushes the knocking rod 4, so that the knocking rod 4 knocks on the arc-shaped groove 15, thereby shaking off the plastic particles accumulated on the bottom wall of the stirring barrel 1.

[0018] As Figure 1As shown in the figure, an installation box 17 is fixedly installed at the top inside the stirring barrel 1.

A first gear 22 is fixedly installed at the bottom end of the rotating shaft 21. The rotating roller 19 has a hollow interior and is parallel to the rotating shaft 21. The top of the rotating roller 19 rotatably penetrates into the installation box 17.

The two connecting rods 20 are fixedly installed on the rotating roller 19, and multiple stirring rods 25 with different lengths are arranged on each connecting rod 20, and multiple conical spikes 26 are fixedly installed on each stirring rod 25. Figure 1 As shown in the figure, two stirring blades 27 are fixedly installed on the rotating roller 19 below the connecting rods 20. The stirring blades 27 are located above the bidirectional feeding roller 11. As Figure 1 As shown in the figure, a vertical scraping plate 36 is fixedly installed on each connecting rod 20. The scraping plate 36 abuts against the inner wall of the stirring barrel 1 and the bottom ends of the scraping plates 36 are all located above the bidirectional feeding roller 11. When it is necessary to stir the plastic particles, first start the second motor 18, drive the rotating shaft 21 and the first gear 22 to rotate through its output end. The first gear 22 drives the rotating roller 19, the second limiting rings 24, the connecting rods 20 and the stirring blades 27 to rotate through the second gear 23 meshing with it. The connecting rods 20 then drive the stirring rods 25 and the conical spikes 26 to rotate, so as to mix and stir the plastic particles poured into the stirring barrel 1 from the feeding port 2.

[0019] As Figure 1As shown in the figure, a blower 28 and an electric heating box 29 electrically connected to the blower 28 are provided at the top of the mixing barrel 1. The input end of the electric heating box 29 is electrically connected to the blower 28, and a rigid air outlet pipe 30 passing through the mixing barrel 1 and into the rotating roller 19 is fixedly provided at the output end of the electric heating box 29. A bearing 31 is fixedly provided in the rotating roller 19. The air outlet pipe 30 passes through the central hole of the bearing 31 and the two are fixedly connected.

A plurality of first air outlet holes 32 and a plurality of second air outlet holes 33 are respectively provided on the connecting rod 20 and the mixing blade 27 in one-to-one correspondence. When it is necessary to stir the plastic particles, the blower 28 and the electric heating box 29 are respectively started. After the electric heating box 29 is started, the electric heating wire inside it will generate heat by being energized. The operator can adjust the electric heating temperature of the electric heating wire according to the drying requirement so that its electric heating temperature does not exceed the drying temperature. The blower 28 in operation sends the heat generated in the electric heating box 29 into the rotating roller 19 through the air outlet pipe 30, and then into the connecting rod 20 and the mixing blade 27 that are electrically connected to the rotating roller 19, so as to discharge air through a plurality of first air outlet holes 32 and a plurality of second air outlet holes 33. The hot air in the rotating roller 19 continues to enter the mounting cylinder 5, enters the mixing shaft 34 through the hollow rotating rod 8, and discharges air through a plurality of third air outlet holes 35, so as to stir and dry the plastic particles in the mixing barrel 1. This design method is convenient for drying the plastic particles in the mixing barrel 1, enables the plastic particles to be fully mixed with hot air, makes the plastic particles mixed and stirred evenly, avoids their agglomeration due to moisture, and makes the discharging effect better.

[0020] Working principle:

[0021] When it is necessary to stir and process the plastic particles and remove moisture, the operator respectively starts the second motor 18, the electric heating box 29, the blower 28 and the first motor 7, and then pours the plastic particles to be processed into the mixing barrel 1 from the feed port 2, so as to stir and dry the plastic particles.

[0022] After the electric heating box 29 is started, the electric heating wire inside it will generate heat by being energized. The operator can adjust the electric heating temperature of the electric heating wire according to the drying requirement so that its electric heating temperature does not exceed the drying temperature. The blower 28 in operation sends the heat generated in the electric heating box 29 into the rotating roller 19 through the rigid air outlet pipe 30, and the hot air in the rotating roller 19 then enters the connecting rod 20, the mixing blade 27, the mounting cylinder 5 and the rotating rod 8 that are electrically connected to the rotating roller 19.

[0023] The second motor 18 during operation drives the rotating shaft 21 and the first gear 22 to rotate through its output end. The first gear 22 drives the rotating roller 19, the second limiting ring 24, the connecting rod 20 and the stirring blades 27 to rotate through the second gear 23 meshing with it. The connecting rod 20 further drives the stirring rod 25 and the conical spikes 26 to rotate, thereby mixing and stirring the plastic particles poured into the mixing barrel 1 from the feed port 2. At the same time, a large amount of hot air is ejected from a plurality of first air outlets 32 and a plurality of second air outlets 33, and stirs and dries the plastic particles in the mixing barrel 1 as the connecting rod 20 rotates.

[0024] The first motor 7 during operation drives the two-way feeding roller 11 and the first bevel gear 9 thereon to rotate through its output end. The two-way feeding roller 11 further drives the plastic particles on both sides of the mounting cylinder 5 to move towards the discharge port 3 through a plurality of opposite spiral fins. The first bevel gear 9 drives the rotating rod 8, the positioning cylinder 13 and the stirring shaft 34 to rotate through the second bevel gear 10 meshing with it. The positioning cylinder 13 pushes the knocking rod 4 against the inner wall of the mixing barrel 1 through the spring 14 inside it. When the knocking rod 4 rotates into the arc-shaped groove 15, the spring 14 pushes the knocking rod 4, causing the knocking rod 4 to knock on the arc-shaped groove 15, thereby shaking off the plastic particles accumulated on the bottom wall of the mixing barrel 1. Moreover, the hot air in the rotating rod 8 enters the stirring shaft 34 and is ejected through a plurality of third air outlets 35 on the stirring shaft 34, and further stirs and dries the plastic particles at the discharge port 3 as the stirring shaft 34 rotates, accelerating the discharge of the plastic particles.
