Abstract
Description
Technical Field
[0001] This utility model belongs to the field of corrugated pipe production technology, specifically a corrugated pipe raw material mixing and isolation device. Background Technology
[0002] In the production process of corrugated pipes, the uniformity of raw material mixing is one of the key factors affecting product quality. Corrugated pipes are usually made from a variety of different raw materials with varying physical and chemical properties. Therefore, an efficient mixing device is needed to ensure that the raw materials are fully mixed to meet the requirements of subsequent molding processes. Traditional corrugated pipe raw material mixing devices usually use a single stirring method, such as setting a stirring paddle in a mixing tank. However, this traditional stirring method has some obvious limitations. First, the stirring range of a single stirring paddle is limited, resulting in some raw materials not being fully mixed. Second, traditional stirring devices cannot effectively prevent raw materials from adhering to the inner wall of the mixing tank. Adhered raw materials not only cause waste but also affect the uniformity of mixing, making it difficult to meet the high precision requirements of corrugated pipe raw material mixing. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides an isolation mixing device for corrugated pipe raw material mixing. It solves the problem that traditional corrugated pipe raw material mixing devices usually adopt a single stirring method. The stirring range of a single stirring paddle is limited, which easily forms a stirring dead zone in the mixing tank, resulting in some raw materials not being fully mixed. Secondly, it cannot effectively prevent the raw materials from adhering to the inner wall of the mixing tank, which not only causes waste but also affects the uniformity of mixing, making it difficult to meet the high precision requirements of corrugated pipe raw material mixing.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a corrugated pipe raw material mixing and isolation device, comprising a base, two mixing chambers symmetrically fixedly installed between the inner walls of the base, two support plates fixedly connected near the top and bottom of the inner walls of the mixing chambers respectively, a rotating rod rotatably connected at the center between the two support plates, two scraping mechanisms symmetrically fixedly connected to the outer walls of the rotating rod, each scraping mechanism comprising an outer sleeve rod, the number of which is two and fixedly connected to the same vertical horizontal line on the outer wall of the rotating rod, an inner sliding rod slidably connected to the end of the outer sleeve rod, two pillars fixedly connected to the inner walls of the inner sliding rod and the opposite end of the outer sleeve rod respectively, the two pillars being sleeved with springs, scrapers fixedly connected to the ends of the two inner sliding rods, the scrapers adhering to the inner walls of the mixing chambers, a control motor provided at the top of the rotating rod, the control motor being fixedly installed above the support plates.
[0005] As a further embodiment of this utility model: a mixing chamber is provided on one side of the base, and a mixing mechanism is provided inside the mixing chamber. The mixing mechanism includes a rotating shaft support, which is rotatably connected to the inner wall of one side of the mixing chamber. Two driven gears are rotatably connected to both ends of the rotating shaft support.
[0006] As a further embodiment of this utility model: a gear ring is fixedly installed on the inner wall of the mixing chamber outside the rotating shaft support, and two driven gears mesh with the teeth of the inner wall of the gear ring. A stirring rod is fixedly connected to one side of the two driven gears. The stirring rod is located inside the mixing chamber. An output motor is fixedly installed on one side of the mixing chamber, and the output end of the output motor is connected to the rotating shaft support.
[0007] As a further embodiment of this utility model: the bottom of the mixing chamber and the two separation chambers are provided with a feeding mechanism, the feeding mechanism includes a collection chamber, the collection chamber is an inclined design facing the center, and the bottom of the collection chamber is fixedly connected to a conveying pipe.
[0008] As a further embodiment of this utility model: a conveying blade is rotatably connected inside the conveying pipe, and a conveying motor is fixedly installed at one end of the conveying pipe, with the output end of the conveying motor connected to one end of the conveying blade.
[0009] As a further embodiment of this utility model: the output end of the conveying pipe in the bottom feeding mechanism of the mixing chamber is connected to one side of the mixing chamber, and the feeding mechanism at the bottom of the mixing chamber and the feeding mechanism at the bottom of the mixing chamber face the same direction.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This corrugated pipe raw material mixing and isolation mixing device, through the setting of a rotating rod and a wall scraping mechanism, allows for the addition of various raw materials into two mixing chambers. The motor drives the rotating rod to rotate, which in turn drives the wall scraping mechanism. Under the elastic force of springs, the outer and inner sliding rods of the wall scraping mechanism ensure that the scraper remains in good contact with the inner wall of the mixing chamber. This structural combination allows the scraper to effectively scrape the raw materials in the mixing chamber during rotation, preventing raw materials from adhering to the inner wall and avoiding waste and uneven mixing caused by material adhesion. Simultaneously, the wall scraping mechanism also performs preliminary mixing of the raw materials during rotation, ensuring a certain degree of mixing before entering the mixing chamber. This provides a better raw material base for subsequent mixing processes, ensuring a more uniform and stable mixing effect for the corrugated pipe raw materials.
[0011] 2. This corrugated pipe raw material mixing and isolation mixing device, through the setting of a mixing mechanism, when using the device, the output motor drives the rotating shaft support to rotate. The rotating shaft support, through the driven gears at both ends, engages with the gear ring on the inner wall of the mixing chamber. This allows the driven gears to rotate along with the rotating shaft support as a whole, while also rotating on their own due to meshing with the gear ring. This, in turn, drives the stirring rod to achieve double rotation. This double stirring method can mix the raw materials in the mixing chamber in multiple dimensions, allowing the raw materials to be fully turned and stirred in the mixing chamber. It avoids the stirring dead zones that may occur in traditional single stirring methods, greatly improves the uniformity of mixing, and effectively improves the mixing efficiency. It ensures that the mixed raw materials can achieve ideal uniformity, providing a high-quality raw material guarantee for subsequent corrugated pipe production. Attached Figure Description

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0014] like Figures 1-6As shown, this utility model provides a technical solution: a corrugated pipe raw material mixing and isolation device, including a base 1, two mixing chambers 2 symmetrically fixedly installed between the inner walls of the base 1, two support plates 3 fixedly connected near the top and bottom of the inner walls of the mixing chambers 2 respectively, a rotating rod 4 rotatably connected at the center between the two support plates 3, two scraping mechanisms 5 symmetrically fixedly connected to the outer wall of the rotating rod 4, the scraping mechanism 5 including an outer rod 501, the number of outer rods 501 is two and fixedly connected to the same vertical horizontal line on the outer wall of the rotating rod 4, an inner sliding rod 502 slidably connected to the end of the outer rod 501, two pillars 503 fixedly connected to the inner wall of the inner sliding rod 502 and the opposite end of the outer rod 501 respectively, and springs 504 are sleeved on the two pillars 503. Through the cooperation of the springs 504 with the outer rods 501 and the inner sliding rods 502, the springs 504... Inside the outer rod 501 and inner slide rod 502, under the action of their elasticity, the scraper 505 can always maintain good contact with the inner wall of the mixing chamber 2, ensuring the stability and reliability of the scraping effect. The scraper 505 is fixedly connected to the ends of the two inner slide rods 502. The scraper 505 is attached to the inner wall of the mixing chamber 2. The top of the rotating rod 4 is equipped with a control motor 6, which is fixedly installed above the support plate 3. Because of the scraping mechanism 5, when the control motor 6 drives the rotating rod 4 to rotate, the scraper 505 can perform scraping operation on the inner wall of the mixing chamber 2. This can effectively prevent the raw materials from adhering to the inner wall of the mixing chamber 2, avoiding waste or uneven mixing due to the adhesion of raw materials. At the same time, the outer rod 501 and inner slide rod 502 can also perform preliminary mixing of the raw materials during the rotation process, so that the raw materials have a certain degree of mixing before entering the mixing chamber 7, improving the overall mixing efficiency. A mixing chamber 7 is provided on one side of the base 1. A mixing mechanism 8 is provided inside the mixing chamber 7. The mixing mechanism 8 includes a rotating shaft support 801, which is rotatably connected to the inner wall of one side of the mixing chamber 7. Two driven gears 802 are rotatably connected to both ends of the rotating shaft support 801. A gear ring 803 is fixedly installed on the inner wall of the mixing chamber 7 outside the rotating shaft support 801. Both driven gears 802 mesh with the teeth on the inner wall of the gear ring 803. A stirring rod 804 is fixedly connected to one side of each of the two driven gears 802. The stirring rod 804 is located inside the mixing chamber 7. An output motor 9 is fixedly installed on one side of the shaft. The output end of the output motor 9 is connected to the rotating shaft bracket 801. Because a mixing mechanism 8 is provided, when the output motor 9 drives the rotating shaft bracket 801 to rotate, the driven gear 802 will rotate along with the rotating shaft bracket 801 and will also rotate due to meshing with the gear ring 803. This allows the stirring rod 804 to not only rotate with the rotating shaft bracket 801 as a whole, but also to rotate on its own, thereby realizing multi-dimensional mixing of the raw materials in the mixing chamber 7. This allows for more thorough mixing of the raw materials, making the mixing more uniform and greatly improving the mixing quality. The bottom of the mixing chamber 7 and the two separation mixing chambers 2 are all equipped with a feeding mechanism 10. The feeding mechanism 10 includes a collection chamber 1001, which is designed to be inclined towards the center. This design allows the raw materials in the separation mixing chamber 2 or the mixing chamber 7 to smoothly converge towards the center of the collection chamber 1001, avoiding the raw materials from being dispersed and accumulated in the collection chamber 1001, thereby improving the conveying efficiency and ensuring that the raw materials can quickly and smoothly enter the conveying pipe 1002. The bottom of the collection chamber 1001 is fixedly connected to the conveying pipe 1002, and a conveying blade 1003 is rotatably connected inside the conveying pipe 1002. One end of the conveying pipe 1002 is fixedly installed with... Equipped with a conveyor motor 11, the output end of the conveyor motor 11 is connected to one end of the conveyor blade 1003. The conveyor motor 11 drives the spiral conveyor blade 1003 inside the conveyor pipe 1002 to rotate, discharging the raw material from the output end of the conveyor pipe 1002. This conveying method has a strong conveying capacity and can avoid blockage of the raw material during the conveying process, ensuring that the raw material can be smoothly and stably conveyed to the next stage. The output end of the conveyor pipe 1002 in the bottom feeding mechanism 10 of the mixing bin 2 is connected to one side of the mixing bin 7. The feeding mechanism 10 at the bottom of the mixing bin 7 and the feeding mechanism 10 at the bottom of the mixing bin 2 face the same direction.
[0015] The working principle of this utility model is as follows: When using this device, different corrugated pipe materials are added to two mixing chambers 2. The control motor 6 is started, and the control motor 6 drives the rotating rod 4 to rotate. The scraping mechanism 5 on the rotating rod 4 moves accordingly. Under the action of the spring 504, the outer rod 501 and inner sliding rod 502 in the scraping mechanism 5 make the scraper 505 tightly adhere to the inner wall of the mixing chamber 2. As the rotating rod 4 rotates, the materials in the mixing chamber 2 are initially mixed. At the same time, the scraper 505 scrapes the material in the mixing chamber 2 to prevent the material from adhering to the inner wall of the mixing chamber 2. After the initial mixing, the material enters the mixing chamber 7 through the feeding mechanism 10 at the bottom of the mixing chamber 2. The collecting chamber 1001 in the feeding mechanism 10 at the bottom of the mixing chamber 2 collects the material and then transports it to the mixing chamber 7 through the conveying pipe 1002. The spiral conveying blade 1003 in the conveying pipe 1002 Driven by the conveying motor 11, the raw materials are smoothly conveyed into the mixing chamber 7 by extrusion conveying. Inside the mixing chamber 7, the output motor 9 is started, which drives the rotating shaft support 801 to rotate. The rotating shaft support 801 drives the two stirring rods 804 to rotate through two driven gears 802. At the same time, the driven gears 802 mesh with the gear ring 803. As the driven gears 802 follow the rotating shaft support 801, they rotate themselves, thereby driving the stirring rods 804 to rotate themselves, further mixing the raw materials entering the mixing chamber 7, so that the raw materials achieve a uniform mixing effect. The mixed raw materials are discharged through the feeding mechanism 10 at the bottom of the mixing chamber 7. The feeding mechanism 10 at the bottom of the mixing chamber 7 uses the same method to discharge the mixed raw materials in the mixing chamber 7 through the output end of the conveying pipe 1002, completing the entire corrugated pipe raw material mixing process.
