Description

Technical Field

[0001] This utility model belongs to the technical field of plastic processing equipment, specifically relating to a vertical mixing device for plastic particles. Background Technology

[0002] In the production of plastic products, the thorough and uniform mixing of plastic particles with various additives such as color masterbatch and functional additives is a key preliminary process to ensure the quality of the final product. Vertical mixers are common equipment for completing this process. Their working principle is usually as follows: the material is placed in the cylinder and vertically conveyed upward by the spiral lifting rod at the bottom. After reaching the top, the material is thrown out through the discharge port and falls back to the bottom of the cylinder under the action of gravity. This cycle is repeated to achieve mixing.

[0003] However, in actual use, the discharge port of the existing vertical mixing machine is usually in a fixed state. After the material is lifted to the top, it can only be thrown down from a fixed, unchanging opening. This fixed-point throwing method causes all the material to fall back into a limited area inside the cylinder, forming an obvious "material pile". It is difficult to cover the corner areas of the cylinder, resulting in a large number of mixing dead zones. Due to the uneven throwing of materials, the distribution pattern of particles of different components (such as base material and color masterbatch) in the cylinder is inconsistent. In order to achieve the expected mixing uniformity, the mixing time has to be greatly extended, resulting in low production efficiency, increased energy consumption, and affecting use. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vertical mixing device for plastic particles includes: a base plate, a lifting cylinder fixedly mounted on the top of the base plate, an inlet and an outlet respectively opened on the outer side wall of the lifting cylinder, an inlet pipe and an outlet pipe respectively fixedly mounted at the inlet and outlet, the inlet pipe and outlet pipe being inclined upward and inclined downward respectively, a mixing frame fixedly mounted at the end of the inlet pipe, the bottom of the mixing frame being frustoconical and having a through opening at the bottom, a flow guiding component and a feeding mechanism being provided below the outlet pipe, and a lifting component being provided on the lifting cylinder;

[0007] The feeding mechanism includes a mounting frame fixedly installed on the top of the base plate. Two symmetrically arranged support frames are fixedly installed on the top of the mounting frame. Both support frames are rotatably connected to the same swing frame via a rotating shaft. The support frame has a swing opening adapted to the swing frame. The openings at the top and bottom of the swing frame gradually narrow from top to bottom and are located directly above the mixing frame. The mounting frame is equipped with a rotating component.

[0008] Preferably, the rotating assembly includes a first geared motor fixedly mounted on the top of the mounting bracket, a rotating rod fixedly mounted on the output end of the first geared motor, and the end of the rotating rod being fixedly connected to the end of the rotating shaft at a corresponding position.

The bottom of the discharge pipe is inserted into the fixed frame, and the bottom of the fixed frame is located within the swing frame.

[0010] Preferably, a plurality of guide plates are provided below the discharge pipe. The guide plate directly below the discharge pipe is vertically arranged, while the plurality of guide plates on both sides are inclinedly arranged, and the plurality of guide plates are arranged in a fan shape as a whole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a swing frame located below the discharge pipe, driven by a first geared motor to reciprocate. This allows material falling from the discharge pipe to be caught and thrown out by a continuously and regularly swinging container. This completely changes the landing point of the material within the mixing frame, enabling the final landing point to move continuously over a large area. This significantly expands the material's coverage area, effectively eliminates mixing dead zones within the mixing frame, and avoids the problems of concentrated material accumulation and uneven mixing caused by fixed discharge ports in traditional vertical mixers, thus improving the mixing effect.

[0021] 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.

[0022] Example 1:

[0023] Please see Figure 1 - Figure 4 As shown, a vertical mixing device for plastic particles includes: a base plate 1, a lifting cylinder 2 fixedly installed on the top of the base plate 1, an inlet and an outlet respectively opened on the outer side wall of the lifting cylinder 2, an inlet pipe 3 and an outlet pipe 4 respectively fixedly installed at the inlet and outlet, the inlet pipe 3 and the outlet pipe 4 are respectively inclined upward and inclined downward, a mixing frame 5 is fixedly installed at the end of the inlet pipe 3, the bottom of the mixing frame 5 is shaped like a frustum and has a through opening at the bottom, a flow guiding component and a feeding mechanism are provided below the outlet pipe 4, and a lifting component is provided on the lifting cylinder 2;

[0024] The feeding mechanism includes a mounting frame 6 fixedly installed on the top of the base plate 1. Two symmetrically arranged support frames 7 are fixedly installed on the top of the mounting frame 6. Both support frames 7 are rotatably connected to the same swing frame 8 through a rotating shaft 9. The support frame 7 has a swing opening adapted to the swing frame 8. The openings at the top and bottom of the swing frame 8 are gradually narrowed from top to bottom and are located directly above the mixing frame 5. The mounting frame 6 is equipped with a rotating component.

[0025] The rotating assembly includes a first geared motor 10 fixedly mounted on the top of the mounting bracket 6, a rotating rod 11 fixedly mounted on the output end of the first geared motor 10, and the end of the rotating rod 11 and the end of the rotating shaft 9 at the corresponding position are fixedly connected.

[0026] A fixing frame 17 is fixedly installed on the outer wall of the mixing frame 5. Both the mounting frame 6 and the fixing frame 17 are fixedly installed on the top of the base plate 1 by support rods.

[0027] As can be seen from the above, when the equipment is running, the first reduction motor 10 starts according to the set program and drives the rotating rod 11 to perform forward and reverse rotational motion through its output end. Since the rotating rod 11 is fixedly connected to the end of the rotating shaft 9, the rotational motion is directly transmitted to the rotating shaft 9, thereby driving the entire swing frame 8 to swing regularly at a specific angle with the hinge point (i.e., the rotating shaft 9) of it and the support frame 7 as the axis.

[0028] This mechanical action changes the traditional fixed discharge port mode of vertical mixers. The material falling from the discharge pipe 4 is received into the swing frame 8 which is in swing motion, and then thrown out from the gradually narrowing outlet at the bottom. Since the swing frame 8 itself is constantly moving, the final landing point of the material sweeps continuously in a linear trajectory in the plane above the mixing frame 5, rather than being fixed at a point. This greatly expands the coverage area of ​​the material in the mixing frame 5, effectively eliminates the mixing dead corners at the edges, and facilitates high-speed and high-uniformity mixing processing.

[0029] Specifically, regarding the aforementioned flow guiding component, the flow guiding component includes a fixed frame 12, which is located directly below the discharge pipe 4, and a swing frame 8 is located directly below the fixed frame 12. The bottom of the discharge pipe 4 is inserted into the fixed frame 12, and the bottom of the fixed frame 12 is located inside the swing frame 8.

[0030] Multiple guide plates 13 are provided below the discharge pipe 4. The guide plate 13 directly below the discharge pipe 4 is vertically arranged, while multiple guide plates 13 on both sides are inclined and the multiple guide plates 13 are arranged in a fan shape.

[0031] Each of the two support frames 7 has multiple fixing rods 14 fixedly installed at one end, and the ends of the multiple fixing rods 14 are fixedly installed on the outer wall of the fixing frame 12.

[0032] As can be seen from the above, the fixed frame 12 is securely suspended on the support frame 7 by multiple fixed rods 14. Its core function is to provide a buffer and pre-dispersion space for the material falling from the discharge pipe 4. After the material is collided and guided by the fan-shaped distribution of the guide plates 13, the originally concentrated material flow is effectively dispersed into multiple evenly distributed material flows, and then falls smoothly into the swing frame 8 below it. This avoids the wear, splashing or accumulation that may be caused by a large amount of material concentrating on a certain point on the inner wall of the swing frame 8, and ensures the uniformity and stability of the material receiving in the swing frame 8, which is convenient for subsequent large-area uniform material spreading.

[0033] Example 2:

[0034] The lifting assembly includes a spiral conveyor rod 15 rotatably disposed inside the lifting cylinder 2. A second reduction motor 16 is fixedly disposed on the top of the lifting cylinder 2. The top of the spiral conveyor rod 15 passes through the top of the lifting cylinder 2 and is fixedly connected to the output end of the second reduction motor 16.

[0035] As can be seen from the above, after the second reduction motor 16 starts, it drives the screw conveyor 15 to rotate at high speed inside the lifting cylinder 2. The mixed material located at the bottom of the mixing frame 5 enters the bottom of the lifting cylinder 2 through the bottom opening and feed pipe 3 under the action of gravity. The blades of the rotating screw conveyor 15 continuously push the material from the bottom upward until it is discharged from the discharge pipe 4 located at the top of the lifting cylinder 2, thus completing one lifting cycle. Through multiple lifting cycles, the material is mixed evenly, and the mixing work is completed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
