Description

Technical Field

[0001] This utility model belongs to the field of mixing technology, and in particular relates to a high-efficiency mixing device for plastic film raw materials. Background Technology

[0002] The mixing process of plastic film raw materials often suffers from problems such as uneven mixing and low efficiency. Traditional mixing devices usually rely on high-speed rotation to achieve rapid mixing of raw materials. However, this method often leads to localized overheating or excessive shearing of the raw materials during the mixing process, thereby affecting the quality stability of the final product.

[0003] According to a disclosed high-efficiency mixing device for plastic film raw materials (publication number: CN209158632U), the device includes a mixing chamber. Two sets of bearings are fixedly installed on the inner walls of both sides of the inner cavity of the mixing chamber. A hollow rotating tube is rotatably connected between the bearings. The inner wall of the hollow rotating tube is threaded. Several stirring rods are fixedly connected to the side wall of the hollow rotating tube. A lead screw is movably connected to the inner cavity of the hollow rotating tube. A power transmission mechanism is provided at the left end of the lead screw. A discharge pipe is fixedly connected to the right side of the mixing chamber. This utility model has a simple structure, is convenient and practical. The stirring rods continuously move clockwise and counterclockwise within the mixing chamber, fully mixing the raw materials in the mixing chamber, improving the mixing effect of the plastic film raw materials, and is easy to promote and apply.

[0004] In the aforementioned application, the stirring rod reciprocates within the mixing chamber by means of the threaded engagement between the lead screw and the inner wall of the hollow rotary tube. While this improves the mixing effect, the reciprocating speed and stirring force of the stirring rod are difficult to control during the mixing process. This may lead to excessive local compression or stretching of the raw materials during the mixing process, thereby affecting the uniformity of the mixing of the raw materials and the quality of the final product. Therefore, we propose an efficient mixing device for plastic film raw materials. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency mixing device for plastic film raw materials. Through the cooperation between components such as the fixed plate, motor, and gear one in the mixing device, the mixing shaft can rotate at a relatively slow speed while maintaining high torque output, thus enhancing the mixing effect. The difference in the number of teeth between gear one and gear two avoids the problem of uneven mixing of raw materials caused by excessively fast mixing speeds in traditional mixing devices when the motor drives the mixing shaft to rotate, thus solving the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a high-efficiency mixing device for plastic film raw materials, including a tank and a bottom support base. The top of the tank is fixedly connected to the top of the bottom support base. A feed pipe is fixedly connected through the circumference of the tank and a discharge pipe is fixedly connected through the circumference of the tank. A stirring device is provided on the top of the tank.

[0008] The stirring device includes a fixed plate, which is fixedly connected to the top of the tank. A motor is fixedly connected to the side of the fixed plate. A gear is fixedly connected to the output shaft of the motor. A rotating sleeve is rotatably connected through the top of the tank. A stirring shaft is rotatably connected to the inner circumference of the rotating sleeve. A stirring rod is fixedly connected to the circumference of the stirring shaft. A gear is fixedly connected to one end of the stirring shaft. A limit sleeve is rotatably connected to the end of the stirring rod away from the gear.

[0009] Furthermore, a protective cover is fixedly connected to the top of the tank, and an oil drip hole is provided on the top of the protective cover. Its function is to lubricate the gears and other components in the stirring device, prevent excessive wear between components, and improve the service life of the device.

[0010] Furthermore, gear one and gear two mesh with each other, with gear one having slightly more teeth than gear two. The purpose of this difference in the number of teeth between gear one and gear two is to allow the stirring shaft to rotate at a slower speed under the drive of the motor while maintaining a higher torque, thereby enhancing the stirring effect and enabling the plastic film raw materials to be mixed more evenly.

[0011] Furthermore, the number of stirring rods is set to several and arranged linearly along the circumference of the stirring shaft. The circumference of the motor output shaft passes through and is rotatably connected to the top of the protective cover. Its function is to ensure that the stirring range covers all corners of the tank by arranging multiple stirring rods linearly along the circumference of the stirring shaft, thereby improving the mixing efficiency. At the same time, it ensures the stable rotation of the motor output shaft and avoids shaking or jamming.

[0012] Furthermore, a scraping-assisted stirring device is provided on the circumferential surface of the stirring shaft. The scraping-assisted stirring device includes a limiting post, which is fixedly connected to the circumferential surface of the stirring shaft. A tension spring is fixedly connected to the inner side of the limiting post. A sliding plate is fixedly connected to the end of the tension spring away from the limiting post. A scraper column is fixedly connected to the side of the sliding plate. A scraper blade is fixedly connected to the end of the scraper column away from the sliding plate. Its function is that during the stirring process, the scraper blade can slide closely against the inner wall of the tank through centrifugal force to scrape off the plastic film material attached to the inner wall of the tank, avoiding waste of material and enhancing the stirring effect.

[0013] Furthermore, the side of the sliding plate is slidably connected to the inner side of the limiting post, and the side of the scraper is slidably connected to the inner wall of the tank. Its function is to ensure that the scraper can remain stable during the scraping process, and at the same time move flexibly along the inner wall of the tank as the stirring shaft rotates, thereby improving the efficiency and uniformity of scraping.

[0014] Furthermore, the number of limiting posts, tension springs, sliding plates, and scraper posts is set to several, and they are arranged in a linear array along the circumference of the stirring shaft. Their function is to further enhance the scraping effect and stirring range of the scraping-assisted stirring device, ensure that all positions on the inner wall of the tank can be effectively scraped and stirred, and improve the mixing uniformity and production efficiency of plastic film raw materials.

[0015] This utility model has the following beneficial effects:

[0016] 1. This invention, through the coordinated operation of components such as the fixed plate, motor, and gear one in the mixing device, achieves high torque output while maintaining a slower rotation speed of the mixing shaft, thus enhancing the mixing effect. The difference in the number of teeth between gear one and gear two allows the motor to drive the mixing shaft more smoothly and powerfully, avoiding the uneven mixing problem caused by excessively fast mixing speeds in traditional mixing devices. This improves the mixing efficiency of plastic film raw materials and ensures the uniformity and stability of the materials during the mixing process, providing a strong guarantee for subsequent production and processing.

[0017] 2. This utility model, through the coordinated operation of components such as the limiting column, tension spring, and sliding plate in the scraper-assisted stirring device, enables the scraper to slide closely against the inner wall of the tank during the stirring process. This effectively scrapes off the plastic film material adhering to the inner wall of the tank, avoiding material waste and further enhancing the stirring effect. It also ensures thorough and uniform stirring, making the mixed plastic film material more in line with production requirements. Furthermore, the reasonable number of components in the scraper-assisted stirring device, arranged linearly along the circumference of the stirring shaft, further increases the scraping effect and stirring range, improving overall production efficiency.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model is a high-efficiency mixing device for plastic film raw materials, including a tank body 1 and a bottom support 2. The top of the tank body 1 is fixedly connected to the top of the bottom support 2. A feed pipe 3 is fixedly connected through the circumference of the tank body 1, and a discharge pipe 4 is fixedly connected through the circumference of the tank body 1. A stirring device 5 is provided on the top of the tank body 1.

[0029] The stirring device 5 includes a fixing plate 501, which is fixedly connected to the top of the tank 1. A motor 502 is fixedly connected to the side of the fixing plate 501. A gear 503 is fixedly connected to the output shaft of the motor 502. A rotating sleeve 504 is rotatably connected through the top of the tank 1. A stirring shaft 505 is rotatably connected to the inner circumferential surface of the rotating sleeve 504. A stirring rod 506 is fixedly connected to the circumferential surface of the stirring shaft 505. A gear 507 is fixedly connected to one end of the stirring shaft 505. A limit sleeve 508 is rotatably connected to the end of the stirring rod 506 away from the gear 507.

[0030] As shown in the figure, a protective cover 6 is fixedly connected to the top of the tank 1. The top of the protective cover 6 has an oil drip hole 7, which is used to lubricate the gears and other components in the stirring device 5, prevent excessive wear between components, and improve the service life of the device.

[0031] As shown in the figure, gear 1 503 and gear 2 507 mesh with each other. Gear 1 503 has slightly more teeth than gear 2 507. The function of this difference in the number of teeth between gear 1 503 and gear 2 507 is to enable the stirring shaft 505 to rotate at a slower speed under the drive of motor 502 while maintaining a higher torque, thereby enhancing the stirring effect and allowing the plastic film raw materials to be mixed more evenly.

[0032] As shown in the figure, there are several stirring rods 506 arranged in a linear array along the circumference of the stirring shaft 505. The circumference of the output shaft of the motor 502 is connected to the top of the protective cover 6 through and rotates. The function of the multiple stirring rods 506 arranged in a linear array along the circumference of the stirring shaft 505 is to ensure that the stirring range covers all corners of the tank 1, improve the mixing efficiency, and at the same time ensure the stable rotation of the output shaft of the motor 502 to avoid shaking or jamming.

[0033] As shown in the figure, a scraping auxiliary stirring device 8 is provided on the circumferential surface of the stirring shaft 505. The scraping auxiliary stirring device 8 includes a limiting post 801, which is fixedly connected to the circumferential surface of the stirring shaft 505. A tension spring 802 is fixedly connected to the inner side of the limiting post 801. A sliding plate 803 is fixedly connected to the end of the tension spring 802 away from the limiting post 801. A scraper column 804 is fixedly connected to the side of the sliding plate 803. A scraper blade 805 is fixedly connected to the end of the scraper column 804 away from the sliding plate 803. Its function is that during the stirring process, the scraper blade 805 can slide closely against the inner wall of the tank 1 through centrifugal force to scrape off the plastic film material attached to the inner wall of the tank 1, thereby avoiding waste of material and enhancing the stirring effect.

[0034] As shown in the figure, the side of the slide plate 803 is slidably connected to the inner side of the limiting post 801, and the side of the scraper 805 is slidably connected to the inner wall of the tank 1. Its function is to ensure that the scraper 805 can remain stable during the scraping process, and move flexibly along the inner wall of the tank 1 as the stirring shaft 505 rotates, thereby improving the efficiency and uniformity of scraping.

[0035] As shown in the figure, there are several limiting posts 801, tension springs 802, sliding plates 803 and scraper posts 804, which are arranged in a linear array along the circumference of the stirring shaft 505. Their function is to further enhance the scraping effect and stirring range of the scraping auxiliary stirring device 8, ensure that all positions on the inner wall of the tank 1 can be effectively scraped and stirred, and improve the mixing uniformity and production efficiency of the plastic film raw materials.

[0036] One specific application of this embodiment is as follows: After the motor 502 starts, its output shaft drives gear 503 to rotate. Since gear 503 meshes with gear 507, and gear 503 has slightly more teeth than gear 507, gear 507 rotates at a slower speed while maintaining a higher torque. This allows the stirring shaft 505 to drive the stirring rod 506 to stir the plastic film material in the tank 1 at an appropriate speed and force, ensuring that the material is fully and evenly mixed. During the stirring process, the scraper-assisted stirring device 8 plays an important role. As the stirring shaft 505 rotates, the scraper 805 slides against the inner wall of the tank 1 under the action of centrifugal force, scraping off the plastic film material attached to the inner wall of the tank 1. At the same time, due to the elasticity of the tension spring 802, the sliding plate 803 and the scraper column 804 can move flexibly along the inner wall of the tank 1 as the stirring shaft 505 rotates, ensuring that the scraping process is stable and efficient. In addition, the design of the oil drip hole 7 also facilitates the operation of the device. By adding lubricating oil to the drip hole 7, the gears and other components in the stirring device 5 can be lubricated.
