Description

Technical Field

[0001] This utility model relates to the field of plastic production, and in particular to a modified plastic production proportioning mixer. Background Technology

[0002] In the production of modified plastics, proportioning and mixing is a crucial step that determines product performance, requiring the base resin and additives to be mixed uniformly in precise proportions. Currently, traditional proportioning mixers mostly adopt a fixed feed port design, which requires pre-weighing and controlling the proportions of various raw materials, and then sequentially adding them into the mixing drum for mixing.

[0003] However, this simple feeding method easily leads to localized accumulation within the mixing drum, especially with raw materials exhibiting significant differences in density and particle size. This can result in stratification, leading to poor initial mixing. Furthermore, once the raw materials enter the mixing drum, they rely entirely on the agitator for mixing. The agitator needs to spend a considerable amount of time breaking up the initial accumulation and stratification, which not only prolongs the overall mixing time and reduces production efficiency but may also cause raw material particle breakage or performance degradation due to over-mixing. In addition, simply increasing the agitator speed or extending the mixing time to compensate for the lack of mixing effect undoubtedly increases energy consumption and does not meet the requirements of energy-saving production.

[0004] Therefore, it is necessary to provide a new modified plastics production proportioning mixer to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a modified plastic production proportioning mixer.

[0006] This utility model provides a modified plastic production proportioning mixer comprising: a base, on which a mixing cylinder is fixedly connected, a stirring assembly is installed inside the mixing cylinder, multiple branch seats are provided on the outer side of the base, each branch seat is connected to a storage bin, a spiral feed pipe is provided at the lower end of each storage bin, and the output ends of each spiral feed pipe are located above the mixing cylinder; a pre-mixing mechanism comprising a rotating ring located above the base, the multiple branch seats being fixedly connected to the side wall of the rotating ring, multiple pins being provided on the upper surface of the base, each pin being fixedly connected to a built-in abutment wheel, and a driving assembly being provided between the rotating ring and the base.

[0007] Preferably, the plurality of pins are arranged in an equidistant ring, and the plurality of built-in abutment wheels abut against the inner wall of the rotating ring.

[0008] Preferably, the drive assembly includes a fixed gear ring, which is fixedly connected to the side wall of the rotating ring, and a side gear is provided on one side of the fixed gear ring, which meshes with the fixed gear ring.

[0009] Preferably, a motor is provided on one side of the base, the output end of the motor is fixedly connected to a side gear, and a side mounting seat is provided on one side of the base, on which the motor is fixedly mounted.

[0010] Preferably, one end of each of the multiple branch seats is provided with a stabilizing arc plate, and each of the multiple stabilizing arc plates is provided with multiple load-bearing rollers.

[0011] Preferably, the lower end of the stabilizing arc plate is provided with multiple embedded mounting slots, and the multiple load-bearing wheels are respectively installed in the multiple embedded mounting slots.

[0012] Compared with related technologies, the modified plastic production proportioning mixer provided by this utility model has the following beneficial effects:

[0013] 1. This utility model uses a rotating ring to drive multiple branch seats to drive multiple spiral feed pipes to rotate, so that the feeding port alternately changes position above the mixing cylinder. Different raw materials can achieve preliminary mixing during the falling process, which reduces the workload of subsequent mixing components. Compared with the mixing method with a fixed feeding port, pre-mixing can make the raw materials reach a certain uniformity in the early stage of mixing, effectively shortening the overall mixing time and significantly improving production efficiency.

[0014] 2. This utility model provides stable guidance by having multiple built-in abutment wheels arranged in a ring at equal intervals on the base to abut against the inner wall of the rotating ring. Combined with multiple sets of load-bearing rotating wheels, it further enhances the support and ensures that the multiple storage bins and the spiral feed pipe rotate smoothly, avoiding fluctuations in the amount of raw materials conveyed due to shaking. Moreover, the spiral feed pipe precisely controls the amount of raw materials output. With the alternating feeding method, it can maintain the accuracy of the proportion and mixing degree of each raw material during the pre-mixing process, thereby ensuring the stability of the quality of modified plastic products.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 3 A modified plastic production proportioning mixer includes: a base 1, a mixing cylinder 2 fixedly connected to the base 1, a stirring assembly 21 installed inside the mixing cylinder 2, multiple branch seats 3 on the outer side of the base 1, a storage bin 31 installed on each of the multiple branch seats 3, a spiral feed pipe 32 at the lower end of each of the multiple storage bins 31, and the output ends of the multiple spiral feed pipes 32 located above the mixing cylinder 2; a pre-mixing mechanism including a rotating ring 4 located above the base 1, multiple branch seats 3 fixedly connected to the side wall of the rotating ring 4, multiple pins 41 on the upper surface of the base 1, a built-in abutment wheel 42 fixedly connected to each of the multiple pins 41, and a driving assembly between the rotating ring 4 and the base 1.

[0021] In the specific implementation process, such as Figure 2 and Figure 3 As shown, multiple pins 41 are arranged in an equidistant ring, and multiple built-in abutment wheels 42 abut against the inner wall of the rotating ring 4.

[0022] It should be noted that: the rotating ring 4 rotates stably, driving multiple branch seats 3 to rotate together with the rotating ring 4, thereby driving the storage bin 31 and the spiral feed pipe 32 to rotate synchronously. During the rotation, the output ends of multiple spiral feed pipes 32 alternately change positions above the mixing cylinder 2. Due to the continuous change of the feeding port position, different raw materials will intertwine and initially mix during the process of falling into the mixing cylinder 2.

[0023] The equidistant ring-shaped pins 41 allow the built-in abutment rollers 42 to be evenly distributed inside the rotating ring 4, ensuring that the rotating ring 4 is subjected to balanced force and making the rotating ring 4 rotate more smoothly. At the same time, they play a radial limiting role for the rotating ring 4, preventing the rotating ring 4 from radially deviating during rotation and ensuring that the output ends of the multiple spiral feed tubes 32 can move stably above the mixing cylinder 2.

[0024] refer to Figure 1 and Figure 2 As shown, the drive assembly includes a fixed gear ring 5, which is fixedly connected to the side wall of the rotating ring 4. A side gear 51 is provided on one side of the fixed gear ring 5, and the side gear 51 meshes with the fixed gear ring 5.

[0025] It should be noted that the fixed gear ring 5 and the rotating ring 4 are fixed by welding, which ensures a firm connection and reliable power transmission.

[0026] The meshing transmission between the side-mounted gear 51 and the fixed gear ring 5 has the characteristics of precise transmission ratio and high efficiency, which can ensure that the rotating ring 4 rotates at a stable speed, thereby allowing the output ends of multiple spiral feed tubes 32 to change positions alternately in a regular manner, ensuring that different raw materials can be mixed in an orderly manner.

[0027] refer to Figure 1 As shown, a motor 6 is provided on one side of the base 1. The output end of the motor 6 is fixedly connected to the side gear 51. A side mounting seat 7 is provided on one side of the base 1, and the motor 6 is fixedly mounted on the side mounting seat 7.

[0028] It should be noted that motor 6 is a servo motor, which can precisely control the speed and thus adjust the rotation speed of the rotating ring 4 to meet the premixing requirements of different raw materials.

[0029] The side mounting bracket 7 is fixed to the base 1, which can provide a stable mounting foundation for the motor 6, ensure stable meshing between the side gear 51 and the fixed gear ring 5, and improve the working reliability of the drive component.

[0030] refer to Figure 2 As shown, each of the multiple branch seats 3 has a stabilizing arc plate 8 at one end, and each of the multiple stabilizing arc plates 8 has multiple load-bearing wheels 81.

[0031] It should be noted that the stabilizing arc plate 8 and the branch seat 3 are integrated into one design, and the load-bearing rotating wheel 81 is in contact with the ground, which can share the weight of the branch seat 3, the storage bin 31 and other components, reduce the force on the rotating ring 4 and the built-in abutment wheel 42, and roll with the rotating ring 4 to reduce frictional resistance, making the overall rotation lighter and more stable.

[0032] refer to Figure 2 As shown, the lower end of the stabilizing arc plate 8 is provided with multiple embedded mounting slots, and multiple load-bearing wheels 81 are respectively installed in the multiple embedded mounting slots.

[0033] It should be noted that the size of the embedded mounting groove matches that of the load-bearing roller 81, which can axially limit the load-bearing roller 81 and prevent it from axially moving during rolling.

[0034] The working principle of the modified plastic production proportioning mixer provided by this utility model is as follows: First, different types of modified plastic raw materials are added to multiple storage bins 31 respectively, and then multiple spiral feed pipes 32 (existing technology) are used to continuously transport the raw materials in the storage bins 31 to the mixing cylinder 2 in proportion.

[0035] Simultaneously, the motor 6 is started, causing the output end of the motor 6 to drive the side gear 51 to rotate. Since the side gear 51 meshes with the fixed gear ring 5 and the fixed gear ring 5 is fixedly connected to the side wall of the rotating ring 4, the rotating ring 4 will rotate synchronously under the drive of the side gear 51. When the rotating ring 4 rotates, its inner wall abuts against the built-in abutment rollers 42 on multiple pins 41. The multiple built-in abutment rollers 42 play a supporting and guiding role, ensuring that the rotating ring 4 rotates stably. At the same time, it drives multiple branch seats 3 to rotate together with the rotating ring 4, thereby driving the storage bin 31 and the spiral feed pipe 32 to rotate synchronously.

[0036] During rotation, the output ends of multiple spiral feed pipes 32 alternately change positions above the mixing cylinder 2. Due to the constantly changing position of the feed inlet, different raw materials intertwine and undergo preliminary mixing as they fall into the mixing cylinder 2. Subsequently, the stirring assembly 21 (existing technology) inside the mixing cylinder 2 is activated to further stir and mix the pre-mixed raw materials, ultimately completing the proportioning and mixing of the modified plastic. In addition, the load-bearing roller 81 on the stabilizing arc plate 8 at one end of the branch seat 3 contacts the ground, providing additional support for the rotation process and enhancing the stability of the overall structure.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
