Description

Technical Field

[0001] This utility model relates to the field of plastic particle mixing technology, and in particular to a plastic particle stirring mechanism. Background Technology

[0002] Plastic particle mixing mechanisms are devices used to mix, stir, and homogenize plastic particles such as PP, PE, and ABS. They are widely used in the plastics processing industry, such as raw material pretreatment before injection molding and extrusion. Their core function is to thoroughly mix different types, colors, or additives of plastic particles through mechanical motion, ensuring the uniform and stable quality of subsequently processed products.

[0003] In a single mixing structure, such as equipment that only uses a mixing plate for horizontal mixing, plastic granules are prone to exhibiting a phenomenon where "the upper layer of material is highly fluid, while the lower layer is piled up and difficult to move" due to gravity. This leads to uneven mixing between the upper and lower layers, especially for granules with differences in density or particle size, which may result in obvious stratification. This directly affects the quality stability of subsequently processed products.

[0004] In response to the technical problems of insufficient material mixing and easy separation of upper and lower layers in traditional mixing mechanisms, this application proposes a plastic particle mixing mechanism. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of traditional mixing mechanisms, such as insufficient material mixing and easy separation of upper and lower layers. The proposed plastic particle mixing mechanism stirs the plastic particles while the propeller blades turn the plastic particles at the bottom upwards, so that the internal plastic particles are fully mixed, avoiding the problem of material separation between upper and lower layers. It also causes the discharge pipe to vibrate, which can effectively prevent the plastic particles from clogging during the discharge process and ensure the stability of the discharge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic particle mixing mechanism, comprising a mixing tank, a feed pipe fixedly connected to the top of the mixing tank, a first motor fixedly connected to the top of the mixing tank, a rotating shaft fixedly connected to the drive end of the first motor, the outer wall of the rotating shaft rotatably connected to the inner wall of the mixing tank, multiple mixing plates fixedly connected to the four sides of the outer wall of the rotating shaft, the rotating shaft being connected to a propeller blade through a mixing assembly, a discharge pipe fixedly connected to the bottom of the mixing tank, a second motor fixedly connected to the right end of the discharge pipe, and the second motor being connected to an impact plate through an impact assembly.

[0007] Furthermore, the mixing assembly includes connecting rods fixedly connected to the four sides of the outer wall of the rotating shaft, and an external gear ring fixedly connected to the other end of the connecting rod. Gears are meshed and connected to the four sides of the outer wall of the external gear ring.

[0008] Furthermore, a connecting shaft is fixedly connected to the inner wall of the gear, the outer wall of the connecting shaft is rotatably connected to the inner wall of the mixing tank, and the inner side of the propeller blade is fixedly connected to the outer wall of the connecting shaft.

[0009] Furthermore, a sleeve is fixedly connected to the bottom of the inner wall of the mixing tank, the propeller blade is located on the inner wall of the sleeve, and an opening is provided at the bottom of the sleeve.

[0010] Furthermore, a partition is fixedly connected to the inner wall of the mixing tank, the partition is located below the outer toothed ring, and the outer wall of the feed pipe is fixedly connected to the inner wall of the partition.

[0011] Furthermore, the impact assembly includes a turntable fixedly connected to the drive end of the second motor, a control column fixedly connected to the eccentric left end of the turntable, a moving rod sleeved on the outer wall of the control column, and the outer wall of the moving rod slidably connected to the inner wall of the discharge pipe.

[0012] Furthermore, the moving rod is fixedly connected to connecting support columns on both its front and rear sides, and the impact plates are slidably connected to the inner walls of the support columns.

[0013] Furthermore, springs are fixedly connected to opposite ends of the inner wall of each support column, and the other end of each spring is connected to the impact plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the first motor drives the stirring plate to rotate, which in turn drives the propeller blade to rotate while stirring the plastic particles, turning the plastic particles at the bottom upwards, so that the internal plastic particles are fully mixed, avoiding the problem of material separation between the upper and lower layers, and greatly improving the overall mixing uniformity.

[0016] 2. In this utility model, the turntable is driven to rotate by the second motor, which causes the moving rods on both sides to move back and forth, thereby causing the impact plates on both sides to impact the inner wall of the discharge pipe, causing the discharge pipe to vibrate. This can effectively prevent the plastic particles from clogging during the discharge process and ensure the stability of the discharge. Attached Figure Description

[0024] 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.

[0025] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a plastic particle mixing mechanism, including a mixing tank 1, a feed pipe 2 fixedly connected to the top of the mixing tank 1, a first motor 3 fixedly connected to the top of the mixing tank 1, a rotating shaft 4 fixedly connected to the drive end of the first motor 3, the outer wall of the rotating shaft 4 being rotatably connected to the inner wall of the mixing tank 1, a plurality of mixing plates 5 fixedly connected to the four sides of the outer wall of the rotating shaft 4, and connecting rods 6 fixedly connected to the four sides of the outer wall of the rotating shaft 4. An external toothed ring 7 is fixedly connected to the other end of the connecting rod 6. The outer wall of the external toothed ring 7 has four... Gears 8 are meshed on both sides. A connecting shaft 9 is fixedly connected to the inner wall of gear 8. The outer wall of the connecting shaft 9 is rotatably connected to the inner wall of the mixing tank 1. The inner side of the propeller blade 10 is fixedly connected to the outer wall of the connecting shaft 9. A sleeve 11 is fixedly connected to the bottom of the inner wall of the mixing tank 1. The propeller blade 10 is located on the inner wall of the sleeve 11. An opening 12 is opened at the bottom of the sleeve 11. A partition 21 is fixedly connected to the inner wall of the mixing tank 1. The partition 21 is located below the outer toothed ring 7. The outer wall of the feed pipe 2 is fixedly connected to the inner wall of the partition 21.

[0026] Specifically, plastic granules enter the mixing tank 1 through the feed pipe 2, and the bottom end of the feed pipe 2 passes through the partition 21, so that the plastic granules fall below the partition 21. The partition 21 blocks the plastic granules and prevents them from contacting the outer toothed ring 7 and gear 8 during the mixing process.

[0027] Reference Figures 3-5A discharge pipe 13 is fixedly connected to the bottom of the mixing tank 1. A second motor 14 is fixedly connected to the right end of the discharge pipe 13. A turntable 15 is fixedly connected to the drive end of the second motor 14. A control column 16 is fixedly connected to the eccentric part of the left end of the turntable 15. A moving rod 17 is sleeved on the outer wall of the control column 16. The outer wall of the moving rod 17 is slidably connected to the inner wall of the discharge pipe 13. Connecting support columns 18 are fixedly connected to both the front and rear sides of the moving rod 17. Impact plates 19 are slidably connected to the inner wall of the support columns 18. Springs 20 are fixedly connected to the opposite ends of the inner wall of the support columns 18. The other end of the springs 20 is connected to the impact plates 19.

[0028] Specifically, a control valve is installed on the discharge pipe 13, which can control the opening and closing of the discharge pipe 13. A slot is opened in the inner wall of the discharge pipe 13, and the impact plate 19 and other structures are located inside the slot and move. When the moving rod 17 drives the support columns 18 on both sides to move back and forth, the impact plate 19 impacts the inner wall of the discharge pipe 13 back and forth. The spring 20 inside the support column 18 plays a buffering role to prevent the support column 18 and the impact plate 19 from hitting the inner wall of the discharge pipe 13 and getting stuck on the turntable 15 due to their excessive length.

[0029] Working principle: In use, plastic particles are added to the mixing tank 1 through the feed pipe 2. Then, the first motor 3 is started, which drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the stirring plate 5 on the outer wall to stir and mix the plastic particles. At the same time, the rotating shaft 4 drives the connecting rod 6 to rotate, which in turn drives the external gear ring 7 to rotate, thereby driving the gears 8 on all four sides to rotate. The gears 8 drive the connecting shaft 9 to rotate, which in turn drives the propeller blades 10 to rotate. The plastic particles will enter the sleeve 11 through the opening 12. Leaf 10 transports the plastic granules from the bottom of the inner wall of the mixing tank 1 to the top, thereby mixing the plastic granules evenly. When the plastic granules are discharged from the mixing tank 1, the control valve on the discharge pipe 13 is opened to allow the plastic granules to flow out. At the same time, the second motor 14 is started. The second motor 14 drives the turntable 15 to rotate. The turntable 15 then moves the moving rod 17 back and forth through the control column 16. The moving rod 17 drives the support columns 18 on both sides to move back and forth, causing the impact plate 19 to impact the inner wall of the discharge pipe 13 back and forth, thus preventing the discharge pipe 13 from becoming blocked.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
