Technical Field

[0001] This utility model relates to the field of plastic mixing technology, and in particular to an optimized mixing structure for a biodegradable plastic mixing device. Background Technology

[0002] In the production process of biodegradable plastics, it is necessary to mix various biodegradable plastic granule raw materials. Stirring can fully mix these raw materials through physical action, ensuring that each part contains each component in equal proportion.

[0003] Chinese patent announcement number CN222553937U discloses a mixer for biodegradable plastic production. While this equipment can improve the efficiency of mixing raw materials for biodegradable plastic production and achieve high-efficiency mixing, it still has the following drawbacks: The device adopts a single-cylinder fixed design, requiring manual unloading and reloading after mixing, resulting in low equipment utilization. Although the aforementioned prior art uses multi-shaft mixing to shorten the single mixing cycle, continuous production cannot be achieved. To address these shortcomings, we propose an optimized mixing structure for a biodegradable plastic mixing device. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-5 This utility model provides a technical solution: an optimized stirring structure for a biodegradable plastic mixing device, comprising: a base, a stirring structure, and a material cylinder fixing structure.

[0029] The base includes a base 10, a rotating platform 11 rotatably connected to the surface of the base 10, and a rotating assembly disposed on the surface of the base 10 for driving the rotating platform 11 to rotate. The rotating assembly includes a gear ring 20 fixedly mounted on the lower end of the rotating platform 11, a first motor 21 fixedly mounted on the upper surface of the base 10, and a spur gear 22 fixedly mounted on the output end of the first motor 21. The spur gear 22 meshes with the gear ring 20 for transmission. Driving the first motor 21 can drive the spur gear 22 to rotate. By utilizing the meshing transmission between the spur gear 22 and the gear ring 20, the rotating platform 11 can be driven to rotate.

[0030] The material cylinder fixing structure includes a trolley 40, a limiting ring 41 fixedly installed on the upper surface of the trolley 40, a storage cylinder 42 placed on the inner wall of the limiting ring 41, and an assembly component set on one side of the trolley 40 for assembly with the rotary table 11. The bottom end of the trolley 40 is provided with casters 43. When the storage cylinder 42 is placed on the trolley 40, the limiting ring 41 can limit the storage cylinder 42.

[0031] The assembly components include an assembly block 60 fixedly installed on one side of the trolley 40, four sets of assembly bolts 61 threadedly connected to the upper surface of the rotary table 11 in a circumferential array, and four insertion slots respectively opened in a circumferential array on the lower surface of the rotary table 11. There are four trolleys 40. The assembly block 60 is adapted to the insertion slots, and the surface of the assembly block 60 is provided with threaded holes adapted to the assembly bolts 61. After the assembly block 60 is moved to the position of the insertion slot, the assembly bolts 61 are screwed into the threaded holes, so that the assembly block 60 and the rotary table 11 can be assembled as one unit. When the rotary table 11 rotates, the trolley 40 will rotate synchronously with the rotary table 11. The four storage cylinders 42 can be detached and installed using the assembly bolts 61. The universal wheels 43 are set at the bottom of the trolley 40 so that the material flow is more labor-saving after the trolley 40 is separated from the rotary table 11. After the storage cylinders 42 are assembled with the rotary table 11, the universal wheels 43 contact the ground to share the burden of the rotary table 11.

[0032] The stirring structure includes a cylinder 30 fixedly mounted on the upper surface of a rotary table 11, a mounting plate 31 fixedly mounted on the upper surface of the cylinder 30, two stirring rods 32 symmetrically rotatably connected to the lower surface of the mounting plate 31, and a drive assembly disposed on the upper surface of the mounting plate 31 for driving the two stirring rods 32 to rotate. The drive assembly includes a first pulley 50 and a second pulley 51 rotatably connected to the upper surface of the mounting plate 31, a second motor 52 fixedly mounted on the upper surface of the mounting plate 31, and a third pulley 53 fixedly mounted on the output end of the second motor 52. The shaft ends of the first pulley 50 and the second pulley 51 are fixedly connected to the shaft ends of the two stirring rods 32, respectively. The first pulley 50, the second pulley 51, and the third pulley 53 are connected by belt drive. Driving the second motor 52 can drive the third pulley 53 to rotate. The belt drive can drive the first pulley 50 and the second pulley 51 to rotate synchronously, thereby driving the two stirring rods 32 to rotate.

[0033] A baffle 70 is rotatably connected to the lower surface of the mounting plate 31, and the surface of the baffle 70 has a through hole for the shaft end of the stirring rod 32 to pass through. When the storage cylinder 42 rotates to directly below the stirring rod 32, the drive cylinder 30 descends, which can drive the mounting plate 31 to descend synchronously, thereby driving the two stirring rods 32 to enter the two storage cylinders 42 respectively. At this time, the baffle 70 will block the upper end of the storage cylinder 42. When the drive assembly drives the stirring rod 32 to rotate, the plastic particles in the storage cylinder 42 can be stirred. The baffle 70 can prevent plastic particles and dust from splashing during stirring.

[0034] After mixing is complete, the rotating assembly can rotate the other two storage cylinders 42 to below the two stirring rods 32, thereby mixing the other two storage cylinders 42. At the same time, the storage cylinders 42 containing the mixed plastic granules can be separated from the rotating table 11 for unloading and reloading. This allows the operator to load and unload the other two storage cylinders 42 while the mixing structure is mixing the plastic granules in the two storage cylinders 42. The collaborative operation mode of synchronous mixing of the two storage cylinders 42 and parallel loading and unloading at two stations greatly improves efficiency compared to single-cylinder fixed equipment.

[0035] Specifically, the working principle and operation method of this utility model are as follows:

[0036] Mixing stage: The rotary table 11 drives two sets of storage cylinders 42 to the mixing position, the cylinder 30 drives the mounting plate 31 to descend, so that the stirring rod 32 extends into the storage cylinder 42, and the baffle 70 closes the cylinder opening; the second motor 52 drives the two stirring rods 32 to rotate to complete the mixing.

[0037] Material changing stage: After mixing is completed, cylinder 30 lifts mixing rod 32, first motor 21 drives rotary table 11 to rotate 90°, so that the mixed storage cylinder 42 moves out of the work position, and at the same time the new storage cylinder 42 enters the mixing position. The operator unloads, cleans and fills the two empty storage cylinders 42 in the non-mixing work position to achieve seamless connection between mixing and material changing.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
