Technical Field
[0001] This utility model relates to the field of plastic granule processing technology, specifically to a high-efficiency continuous stirring device for plastic granules. Background Technology
[0002] In the booming development of the modern plastics industry, plastic granules, as the basic raw material for plastic processing, play a crucial role in the performance of subsequent plastic products due to their processing quality. In the production process of plastic granules, stirring is an indispensable key link, which directly affects the mixing uniformity, physical properties and production efficiency of plastic granules. As various industries continue to increase their requirements for the quality of plastic granules, higher standards are also being put forward for the performance of stirring devices. Currently, relatively mature mixing devices on the market typically consist of a fixed mixing tank and a mixing shaft installed inside the tank. The mixing shaft is equipped with mixing blades. The working process is roughly as follows: a motor drives the mixing shaft to rotate, causing the mixing blades to rotate within the mixing tank, thus mixing the plastic granules. During mixing, the plastic granules enter the mixing tank through the feed inlet and are mixed under the action of the mixing blades. After mixing, they are discharged from the discharge outlet. However, existing traditional mixing devices have some problems in practical applications. Because the mixing shaft can only rotate in one direction, the movement trajectory of the plastic granules within the mixing tank is relatively simple, making it difficult to achieve a sufficient three-dimensional mixing effect. This makes it easy for the plastic granules to be unevenly mixed during the mixing process, especially when processing plastic granules that require high mixing uniformity. Furthermore, the single mixing method results in low mixing efficiency, often requiring a long mixing time to achieve a certain mixing effect, which not only increases the production cycle but also increases energy consumption and production costs. Therefore, we propose a high-efficiency continuous mixing device for plastic granules. Summary of the Invention

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-5 This embodiment provides a technical solution: a high-efficiency continuous stirring device for plastic granules, including a support 1, a control switch 10 at the right end of the support 1, the input end of the control switch 10 being electrically connected to an external power source, and a stirring tank 3 being rotatably connected to the middle of the support 1 (the middle of the support 1 can be rotatably connected to the stirring tank 3 via a bearing), including a stirring assembly 2. Mixing assembly 2 includes a mixing shaft 21, mixing blades 22, driven gear 23, half gear 26, and a half internal gear ring 27. A rotating disk 9 is rotatably connected to the upper interior of the mixing tank 3 (the rotating disk 9 is rotatably connected to the upper interior of the mixing tank 3 via a first sealed bearing). A feed pipe 4 is located at the front end of the rotating disk 9, and a discharge pipe 5 is located at the discharge port at the lower end of the mixing tank 3. Valves 6 are connected in series in the middle of both the feed pipe 4 and the discharge pipe 5. Opening the valve 6 in the middle of the feed pipe 4 allows plastic granules to be fed into the mixing tank 3 through the feed pipe 4. Then, the valve 6 in the middle of the feed pipe 4 is closed. The mixing shaft 21 is rotatably connected to the middle of the rotating disk 9 (the mixing shaft 21 and the middle of the rotating disk 9 are rotatably connected via a second sealed bearing). The lower end of the mixing shaft 21 has evenly distributed... The stirring blades 22 and driven gear 23 are located on the upper end of the outer arc surface of the stirring shaft 21. The upper end of the rotating disk 9 is provided with a half-gear 26 and a half-internal gear ring 27, both of which are fitted with the driven gear 23. The stirring assembly 2 also includes a rotating shaft 24 and a mounting bracket 25. The rear end of the bracket 1 is provided with a mounting plate 11 (the rotating disk 9 is fixedly connected to the mounting plate 11; when the stirring tank 3 rotates, the rotating disk 9 does not rotate). The rotating shaft 24 is rotatably connected to the lower side of the mounting plate 11. The half-gear 26 is located at the lower end of the rotating shaft 24. The mounting bracket 25 is located in the middle of the outer arc surface of the rotating shaft 24. The half-internal gear ring 27 is fixedly connected to the lower side of the mounting bracket 25. The upper side of the mounting plate 11 is provided with a motor 7, and the output shaft of the motor 7 is connected to the upper side of the rotating shaft 24. The mixing assembly 2 is fixedly connected at the center of the end face. The input end of the motor 7 is electrically connected to the output end of the control switch 10. The mixing assembly 2 also includes an external gear ring 28 and a gear 29. The external gear ring 28 is fixedly connected to the outer arc surface of the mixing tank 3. The rear end of the support 1 is provided with a gear 29, which meshes with each other. The rear end of the support 1 is provided with a plate. The gear 29 is rotatably connected to the lower side of the plate through a rotating shaft 12. The upper side of the plate is equipped with a motor 8. The output shaft of the motor 8 passes through the front end of the plate and is fixedly connected to the center of the upper end face of the rotating shaft 12. The input end of the motor 8 is electrically connected to the output end of the control switch 10. By operating the control switch 10, the motor 7 is turned on. The output shaft of the motor 7 drives the rotating shaft 24 to rotate. Because the lower end of the rotating shaft 24 is fixed with a half gear 26, the middle part... The semi-internal gear ring 27 is fixed by the mounting bracket 25. When the output shaft of the motor 7 rotates, the rotating shaft 24 drives the semi-gear 26 and the semi-internal gear ring 27 to rotate around the rotating shaft 24. The semi-gear 26 is an external gear with teeth covering half of the circumference, and the semi-internal gear ring 27 is an internal gear, also covering half of the circumference. The two are symmetrically positioned at 180° on the rotating shaft 24. When the rotating shaft 24 drives the semi-gear 26 to rotate until it meshes with the driven gear 23 at the upper end of the stirring shaft 21, the two form an external meshing transmission. The clockwise rotation of the semi-gear 26 drives the driven gear 23 to rotate counterclockwise through tooth surface meshing, which in turn drives the stirring shaft 21 and the stirring blades 22 at the lower end to rotate counterclockwise. The semi-gear 26 moves from initial contact with the driven gear 23 to disengagement.The driven gear 23 completes half a revolution. As the shaft 24 continues to rotate, the half gear 26 disengages from the driven gear 23, and the half internal gear ring 27 rotates with the mounting bracket 25 until it contacts the driven gear 23, forming an internal meshing transmission between the half internal gear ring 27 and the driven gear 23. The clockwise rotation of the half internal gear ring 27 pulls the driven gear 23 to rotate clockwise through the internal tooth surface, causing the stirring shaft 21 and stirring blades 22 to switch to clockwise rotation. When externally meshed, the two gears rotate in opposite directions; when internally meshed, they rotate in the same direction. Therefore, the alternating meshing of the half gear 26 and the half internal gear ring 27 causes the driven gear 23 to periodically change direction. For every revolution of the shaft 24, the half gear 26 and the half internal gear ring 27 each complete one meshing. During continuous rotation, the stirring shaft 21 rotates in a cycle of counterclockwise → clockwise → counterclockwise, alternating between two rotations. Simultaneously, the control switch 10 activates the motor 8. The output shaft of the motor 8 drives the gear 29 via the rotating shaft 12. The gear 29 meshes with the outer gear ring 28 on the outer arc surface of the mixing tank 3, driving the mixing tank 3 to rotate around the axis at the center of the support 1. The rotation of the mixing tank 3 and the forward and reverse rotation of the stirring blades 22 create a compound motion, resulting in a three-dimensional mixing effect of the plastic granules within the mixing tank 3. After mixing is complete, the motors 7 and 8 are turned off, and the valve 6 of the discharge pipe 5 is opened. Under gravity, the granules are discharged from the discharge port at the bottom of the mixing tank 3 along the discharge pipe 5, achieving more efficient and continuous mixing of the plastic granules.
[0016] The working principle of the high-efficiency continuous mixing device for plastic granules provided by this utility model is as follows: First, open the valve 6 in the middle of the feed pipe 4 to feed the plastic granules into the mixing tank 3 through the feed pipe 4. Then, close the valve 6 in the middle of the feed pipe 4 and operate the control switch 10 to make the motor 7 run. The output shaft of the motor 7 drives the rotating shaft 24 to rotate. Since the lower end of the rotating shaft 24 is fixed with a half gear 26 and the middle part is fixed with a half internal gear ring 27 through the mounting bracket 25, when the output shaft of the motor 7 rotates, the rotating shaft 24 drives the half gear 26 and the half internal gear ring 27 to rotate around the rotating shaft 24 as the center. Among them, the half gear 26 is an external gear structure with teeth accounting for half of the circumference. First, the semi-internal gear ring 27 is an internal gear structure, also covering half a circumference. The two are symmetrically positioned 180° on the rotating shaft 24. When the rotating shaft 24 drives the semi-gear 26 to rotate until it meshes with the driven gear 23 at the upper end of the stirring shaft 21, they form an external meshing transmission. The clockwise rotation of the semi-gear 26, through tooth surface meshing, drives the driven gear 23 to rotate counterclockwise, thereby driving the stirring shaft 21 and the lower stirring blades 22 to rotate counterclockwise. From initial contact with the driven gear 23 to disengagement, the semi-gear 26 drives the driven gear 23 to complete half a revolution. As the rotating shaft 24 continues to rotate, the semi-gear 26 disengages from the driven gear 23. The meshing of the semi-internal gear ring 27 with the mounting bracket 25 causes it to rotate until it contacts the driven gear 23, forming an internal meshing transmission between the semi-internal gear ring 27 and the driven gear 23. The clockwise rotation of the semi-internal gear ring 27 pulls the driven gear 23 to rotate clockwise through the internal tooth surface, causing the stirring shaft 21 and stirring blades 22 to switch to clockwise rotation. When externally meshing, the two gears rotate in opposite directions, and when internally meshing, they rotate in the same direction. Therefore, the alternating meshing of the semi-gear 26 and the semi-internal gear ring 27 causes the driven gear 23 to periodically change direction. For every revolution of the rotating shaft 24, the semi-gear 26 and the semi-internal gear ring 27 each complete one meshing. As the rotating shaft 24 continues to rotate, the stirring shaft 21 completes one revolution. The cycle repeats the alternating rotation of "counterclockwise → clockwise → counterclockwise". At the same time, the control switch 10 drives the motor 8. The output shaft of the motor 8 drives the gear 29 to rotate through the rotating shaft 12. The gear 29 meshes with the outer gear ring 28 on the outer arc surface of the mixing tank 3, driving the mixing tank 3 to rotate around the axis in the middle of the support 1. The rotation of the mixing tank 3 and the forward and reverse rotation of the mixing blades 22 form a compound motion, so that the plastic particles produce a three-dimensional mixing effect in the mixing tank 3. After the mixing is completed, the motor 7 and the motor 8 are turned off, and the valve 6 of the discharge pipe 5 is opened. The particles are discharged from the discharge port at the lower end of the mixing tank 3 along the discharge pipe 5 under the action of gravity.
[0017] It is worth noting that the motor 7 disclosed in the above embodiments can be model YCT160-4A, the motor 8 can be model RV130-30-5.5kW, and the control switch 10 is provided with control buttons that correspond one-to-one with the motor 7 and the motor 8 for controlling their switching.
