Description

Technical Field

[0001] This utility model relates to the field of plastic production equipment, specifically a modified engineering plastic mixing and batching machine. Background Technology

[0002] Modified engineering plastics are high-performance materials obtained by optimizing the performance of basic engineering plastics through physical, chemical, or a combination of both methods. Modified engineering plastics are materials that use engineering plastics, such as PA, PC, PBT, POM, and PPO, as the base material and modify their mechanical properties, heat resistance, electrical insulation, chemical resistance, and other characteristics by adding fillers, reinforcing agents, toughening agents, flame retardants, and other additives, or by using processes such as blending, copolymerization, and crosslinking.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN207915803U) discloses a special batching mechanism for the production of modified engineering plastics. Its general description includes a material hopper, a solenoid valve at the lower end of the hopper, a pre-weighing hopper mounted on a frame below the hopper, and an electronic scale connected to the frame. A precision weighing hopper is located below the outlet of the pre-weighing hopper and connected to the frame via a second electronic scale. A receiving hopper is located below the outlet of the precision weighing hopper, and its lower end is connected to the mixing drum via an inclined pipe. This utility model provides a special batching mechanism for the production of modified engineering plastics. Through a rationally designed weighing mechanism, it effectively improves the accuracy of batching and the uniformity of mixing after batching, thus enhancing its performance.

[0004] The above technical solution uses a solenoid valve at the bottom of the material bin to weigh the material in conjunction with a pre-weighing hopper and an electronic scale, and then mixes it inside the mixing drum to achieve accurate batching and uniform mixing. However, during the use of the device, the material bin can only weigh one type of material at a time before it enters the mixing drum. Since the materials to be mixed involve different types, the single-batch feeding efficiency is not high, which affects the work efficiency. When mixing inside the mixing drum, the material is easy to remain on the inner wall, and long-term accumulation can harden it and make it difficult to clean.

[0005] Therefore, this utility model provides a modified engineering plastics mixing and batching machine to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides a modified engineering plastics mixing and batching machine, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a modified engineering plastic mixing and batching machine, comprising a frame, a top plate installed on the top of the frame, a motor located at the center of the top of the top plate, a mixing structure installed inside the frame, a feeding structure at the top of the mixing structure, the feeding structure including a storage box, a feeding structure connected to the outer wall of the storage box, the feeding structure including a connecting chamber and a feeding box, a stirring structure inside the mixing structure, the mixing structure including a mixing box, a conveying structure installed at the bottom of the mixing box, the conveying structure including a through pipe, the through pipe communicating with the interior of the mixing box.

[0018] 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.

[0019] This utility model provides a modified engineering plastics mixing and batching machine, such as... Figure 1 , Figure 2 and Figure 3As shown, the machine includes a frame 1, a top plate 101 mounted on the top of the frame 1, a motor 102 located at the center of the top of the top plate 101, a mixing structure 4 installed inside the frame 1, a feeding structure 2 located on the top of the mixing structure 4, the feeding structure 2 including a storage box 201, a feeding structure 3 connected to the outer wall of the storage box 201, the feeding structure 3 including a connecting chamber 301 and a feeding box 302, a stirring structure inside the mixing structure 4, the mixing structure 4 including a mixing box 401, a conveying structure 5 installed at the bottom of the mixing box 401, the conveying structure 5 including a through pipe 502, the through pipe 502 communicating with the inside of the mixing box 401.

[0020] The top of the frame 1 is symmetrically fixedly connected to the two sides of the top. The top plate 101 is fixedly installed on the top of the column. A through hole is opened at the center of the top of the top plate 101. A motor 102 is fixedly installed on the top of the through hole.

[0021] Storage box 201 has multiple sets arranged in parallel. Inside storage box 201, movable plate 202 is movably installed. The top of movable plate 202 is provided with telescopic spring 203. The telescopic spring 203 is fixedly connected to the outer surface of the top movable plate 202. Electric push rod 204 is fixedly installed on the top of movable plate 202. Connecting rods 205 are evenly distributed on both sides of electric push rod 204 and fixedly connected to movable plates 202 on both sides. One end of electric push rod 204 extends to the inner wall of through hole and is electrically connected to motor 102.

[0022] The connecting chamber 301 is located on the outer wall of the storage box 201. A through groove is provided inside the connecting chamber 301, which extends into the storage box 201. A feeding box 302 is fixedly installed on the top of the storage box 201.

[0023] When in use, the raw materials are added from the feeding box 302 and flow into the storage box 201 through the channel of the connecting chamber 301. The storage box 201 is designed for quantitative feeding. When the storage box is full, the motor 102 drives the electric push rod 204 to press down, which compresses the telescopic spring 203 at the bottom of the electric push rod 204, causing the movable plate 202 to press down. The connecting rod 205 pulls multiple sets of movable plates 202 to move down, and the raw materials enter the mixing structure 4. When resetting, the telescopic spring 203 rebounds upward, causing the movable plate 202 to return to the bottom of the storage box 201 to stop feeding. The parallel design of multiple sets of storage boxes 201 realizes the synchronous feeding of multiple raw materials, thereby improving work efficiency.

[0024] Furthermore, in order to improve the cleaning efficiency of the device, such as Figure 4 As shown, the mixing structure 4 includes a mixing box 401 and a cover plate 402. The cover plate 402 is movably snapped onto both sides of the mixing box 401. The cover plate 402 has an installation hole at its center. A stirring structure is movably installed inside the mixing box 401. The stirring structure includes a rotating shaft 403, a mixing roller 404, and a scraper 405.

[0025] The two ends of the rotating shaft 403 in the stirring structure are located on the inner wall of the mounting hole for rotational connection. Multiple sets of mixing rollers 404 are evenly distributed on the outer surface of the rotating shaft 403. A scraper 405 is fixedly installed on one end of each mixing roller 404. The scraper 405 extends to the inner wall of the mixing box 401. A power interface 406 is installed on one end of the rotating shaft 403.

[0026] The conveying structure 5 also includes a conveying cavity 501. A through pipe 502 is connected to the outer wall of the conveying cavity 501. One end of the through pipe 502 is connected to the inside of the mixing box 401. A rotating shaft is installed inside the conveying cavity 501. A spiral blade 504 is fixedly installed on the outside of the rotating shaft. One end of the rotating shaft is electrically connected to an external motor 503. A conveying pipe 505 is fixedly installed on one side of the conveying cavity 501.

[0027] When the device is in use, after the power interface 406 is connected to an external power source, it drives the rotating shaft 403 to rotate. The mixing roller 404 disperses and mechanically mixes the material. The scraper 405 is in contact with the inner wall of the mixing box 401 and simultaneously scrapes off the material adhering to the inner wall to ensure uniform mixing and avoid prolonged material adhesion. After mixing, the material enters the conveying chamber 501 through the through pipe 502. The motor 503 provides power to drive the rotating shaft and the spiral blade 504 to rotate, conveying and shearing the material, and pushing it along the conveying pipe 505 to the next process to achieve continuous production.

[0028] 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.
