Description

Technical Field

[0001] This utility model relates to the field of mixing machine technology, specifically to an MPP tube mixing machine with a metering structure. Background Technology

[0002] MPP pipe mixers are used to mix the raw materials used in their production, and those with a metering structure are a significant innovation. They typically feature a metering mechanism on a sealed cover, including a positioning frame, a U-shaped frame, and a weighing sensor. Before mixing, the raw materials are placed in a metering funnel, and the weighing sensor monitors the mass in real time to ensure proper metering. The raw materials then fall into the mixing chamber, where they are thoroughly mixed by the stirring blades, improving mixing accuracy and efficiency and ensuring the quality of MPP pipe production.

[0003] According to a public disclosure (CN217144466U), an MPP pipe mixer with a metering structure includes: a sealing cover, a mixing chamber, a sealing gate, a discharge port, and a stirring vane. The sealing cover is equipped with a metering mechanism, which includes a positioning frame, a U-shaped frame, a weighing sensor, a connecting frame, a limiting support, and a metering funnel. The positioning frame is fixedly installed on the sealing cover. A U-shaped frame is located at the top of the positioning frame, and a weighing sensor is located inside the U-shaped frame. Above the weighing sensor is a connecting frame, and the metering funnel is connected to the connecting frame. A limiting mechanism is located at the bottom of the metering funnel, and the limiting mechanism includes a limiting gate, a docking notch, a servo push rod, a mechanism housing, and an inlet / outlet notch. The mechanism housing is fixedly installed at the bottom of the metering funnel. This utility model, an MPP pipe mixer with a metering structure, belongs to the field of mixers and features a metering structure, facilitating the proportioning of raw materials by users.

[0004] In the aforementioned application, the cooperation between the mixing chamber and the sealing plate and other components makes it difficult to continuously meter the raw materials during mixing in the mixing chamber, resulting in poor efficiency of the raw materials in the mixing process. Therefore, we propose an MPP tube mixer with a metering structure. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an MPP tube mixer with a metering structure, which solves the technical problem of poor efficiency in the mixing process in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides an MPP pipe mixer with a metering structure, comprising: a base plate, a control center cabinet disposed on the top of the base plate, a bracket fixedly connected to the top of the base plate, and a metering screw feeding mechanism disposed on the top of the base plate; The metering screw feeding mechanism includes a vertical plate, the bottom of which is fixedly connected to the top of a base plate. A feeding box is fixedly connected to the top of the vertical plate. A motor is fixedly connected to the side of the feeding box. A rotating shaft is fixedly connected to the end of the motor's output shaft. A screw plate is fixedly connected to the circumferential surface of the rotating shaft. A feeding pipe is fixedly connected to the circumferential surface of the feeding box. A transmission pipe is fixedly connected to the circumferential surface of the feeding box. A mixing tank is fixedly connected to one end of the transmission pipe. A metering box is fixedly connected to the side of the support. One end of the feeding pipe is fixedly connected to the side of the metering box. A pressure plate is slidably connected to the inner side of the metering box. A spring is fixedly connected to the bottom of the pressure plate. One end of the spring is fixedly connected to the inner side of the metering box.

[0007] For example, in at least one embodiment of the present invention, an MPP pipe mixer with a metering structure is provided, which further includes: a plurality of springs are provided and are symmetrical about each other along the vertical central axis of the pressure plate. One end of each spring is located on the displacement trajectory of the pressure plate, which can make the pressure plate uniformly subjected to material pressure, avoid the pressure plate tilting or jamming due to uneven force, and ensure the stability and accuracy of the metering process.

[0008] The side of the upright plate has a groove with a radius equal to the outer surface radius of the feed box, which allows the feed box to fit perfectly with the upright plate, forming a tight wrap-around support, improving the stability of the support and preventing it from shifting or rotating laterally during operation.

[0009] The top of the pressure plate is provided with an inclined surface, and one end of the feed pipe is located on the displacement trajectory of the pressure plate. This can guide the material from the metering box to the feed pipe, prevent the material from accumulating locally on the pressure plate, ensure more uniform material distribution during metering, and improve metering accuracy.

[0010] The number of vertical plates is set to two, and they are arranged in a linear array on the top of the base plate to enhance the structural stability of the feed box during operation. One end of the feed pipe is located on the rotation trajectory of the spiral plate to avoid material accumulation and blockage at the feed inlet, and to ensure the continuity and efficiency of material conveying.

[0011] According to another aspect, at least one embodiment of the present invention also provides an MPP pipe mixer with a metering structure, comprising: a stirring mechanism disposed inside the machine body, the stirring mechanism including a protective shell, the bottom of the protective shell being fixedly connected to the top of the mixing tank, a bevel gear one being fixedly connected to the end of the rotating shaft away from the motor, a stirring rod being rotatably connected to the bottom of the mixing tank, a bevel gear two being fixedly connected to one end of the stirring rod, the bevel gear one and the bevel gear two meshing with each other, a stirring plate being engaged on the circumferential surface of the stirring rod, and a locking sleeve being engaged on the circumferential surface of the stirring rod.

[0012] For example, in at least one embodiment of the present invention, an MPP pipe mixer with a metering structure is provided, which further includes: a groove is provided on the circumferential surface of the stirring rod, and the number of grooves is set to a plurality of them and arranged in a circumferential array on the circumferential surface of the stirring rod, which can provide multiple installation positions for the stirring plates, making it convenient to adjust the number and spacing of the stirring plates according to the material characteristics and stirring requirements, thereby enhancing the adaptability of the stirring mechanism.

[0013] The number of stirring plates is set to several and arranged circumferentially on the circumferential surface of the stirring rod to increase the contact area with the material, improve the mixing uniformity, and avoid local accumulation of material. The rotation radius of the stirring plates is smaller than the inner wall size of the mixing box, which can prevent the stirring plates from rubbing and colliding with the inner wall of the mixing box, reduce component wear, and at the same time reserve space for material flow, allowing the material to circulate and tumble fully during the stirring process, ensuring more thorough mixing, and guaranteeing the stable operation of the stirring mechanism and the quality of material mixing.

[0014] The bevel gear one and bevel gear two have spoke holes on their sides. The number of spoke holes is set to a certain number and they are arranged in a circumferential array on the sides of bevel gear one and bevel gear two. While ensuring the structural strength of the bevel gears, the inertia of the bevel gears during rotation is reduced, making the transmission lighter and more flexible, while reducing the load on the drive device and saving energy.

[0015] The rotation radius of the spiral plate is smaller than the inner wall radius of the feed box. One end of the transmission pipe is located on the rotation trajectory of the spiral plate, which can prevent the spiral plate from rubbing or colliding with the inner wall of the feed box during rotation, reduce component wear, ensure the stable operation of the spiral transmission structure, realize the precise transition of materials from the feed box to the subsequent processing stage, reduce material spillage or accumulation, and improve the continuity of the overall process.

[0016] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the stable conveying of materials is achieved through the cooperation of components such as the spiral plate, rotating shaft, and pressure plate inside the metering spiral feeding mechanism. With the spring-loaded pressure plate structure inside the metering box, the feeding amount can be precisely controlled to ensure accurate material ratio. The double vertical plate design enhances the stability of the feeding box, and the matching of the feeding pipe and spiral plate trajectory ensures smooth feeding. The inclined pressure plate and symmetrical spring layout facilitate material introduction and ensure that the pressure plate is evenly stressed and reliably reset, thus improving the efficiency and accuracy of material metering and conveying before mixing.

[0017] In this invention, mixing is achieved through the cooperation of components such as the stirring rod, stirring plate, and bevel gear inside the stirring mechanism. This saves power and ensures efficient and stable transmission. Multiple stirring plates on the stirring rod are arranged in a circumferential array, and their rotation can fully stir the materials and improve the uniformity of mixing. The slot and locking sleeve design facilitates the adjustment and fixation of the stirring plate position to ensure the mixing effect. The protective shell ensures the safety of gear transmission. The overall structure is compact and highly interconnected, which can efficiently complete the mixing of materials, provide stable quality mixtures for MPP pipe production, and improve the overall working efficiency of the equipment.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0022] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, it illustrates an MPP pipe mixer with a metering structure in one embodiment of the present invention, including: a base plate 1, a control center cabinet 2 disposed on the top of the base plate 1, a bracket 3 fixedly connected to the top of the base plate 1, and a metering screw feeding mechanism 4 disposed on the top of the base plate 1. The metering screw feeding mechanism 4 includes a vertical plate 41, the bottom of which is fixedly connected to the top of the base plate 1. A feeding box 42 is fixedly connected to the top of the vertical plate 41. A motor 43 is fixedly connected to the side of the feeding box 42. A rotating shaft 44 is fixedly connected to the end of the output shaft of the motor 43. A screw plate 45 is fixedly connected to the circumferential surface of the rotating shaft 44. A feeding pipe 46 is fixedly connected to the circumferential surface of the feeding box 42. A transmission pipe 48 is fixedly connected to the circumferential surface of the feeding box 42. A mixing tank 49 is fixedly connected to one end of the transmission pipe 48. A metering box 47 is fixedly connected to the side of the support 3. One end of the feeding pipe 46 is fixedly connected to the side of the metering box 47. A pressure plate 410 is slidably connected to the inner side of the metering box 47. A spring 411 is fixedly connected to the bottom of the pressure plate 410. One end of the spring 411 is fixedly connected to the inner side of the metering box 47.

[0028] In some examples, the number of springs 411 is set to several and they are symmetrical to each other along the vertical central axis of the pressure plate 410. One end of the spring 411 is located on the displacement trajectory of the pressure plate 410, which can make the pressure plate 410 uniformly stressed when subjected to material pressure, and prevent the pressure plate 410 from tilting or jamming due to uneven stress, thus ensuring the stability and accuracy of the metering process.

[0029] The side of the upright plate 41 has a groove with a radius equal to the outer surface radius of the feed box 42, which allows the feed box 42 to fit perfectly with the upright plate 41, forming a tight wrap-around support, improving the stability of the support and preventing it from shifting or rotating laterally during operation.

[0030] The top of the pressure plate 410 is provided with an inclined surface, and one end of the feed pipe 46 is located on the displacement trajectory of the pressure plate 410. This can guide the material from the metering box 47 into the feed pipe 46, prevent the material from accumulating locally on the pressure plate 410, ensure more uniform material distribution during metering, and improve metering accuracy.

[0031] There are two vertical plates 41, which are arranged in a linear array on the top of the base plate 1 to enhance the structural stability of the feed box 42 during operation. One end of the feed pipe 46 is located on the rotation trajectory of the spiral plate 45 to prevent material from accumulating and blocking at the feed inlet, thus ensuring the continuity and efficiency of material conveying.

[0032] For example, such as Figures 1-5As shown, the staff places the material in the metering box 47. Under the action of gravity, after reaching a certain weight, the pressure plate 410 moves downward, and the spring 411 contracts. The material enters the feeding box 42 through the feeding pipe 46. The motor 43 is started, and its output shaft drives the rotating shaft 44 to rotate, causing the spiral plate 45 to rotate. The spiral plate 45 pushes the material to move in the feeding box 42. The upright plate 41 stably supports the feeding box 42 through the side groove. The material is finally transported to the mixing box 49 through the transmission pipe 48. When the material in the metering box 47 decreases, the spring 411 resets and pushes the pressure plate 410 to move upward, completing one metering feeding cycle. Throughout the process, the control center cabinet 2 coordinates the operation of each component to ensure continuous feeding and accurate metering.

[0033] like Figures 1-5 As shown, this invention illustrates an MPP pipe mixer with a metering structure in another embodiment of the present invention, comprising: a stirring mechanism 5 disposed on the top of a base plate 1; the stirring mechanism 5 includes a protective shell 51; the bottom of the protective shell 51 is fixedly connected to the top of a mixing tank 49; a bevel gear 52 is fixedly connected to one end of a rotating shaft 44 away from a motor 43; a stirring rod 53 is rotatably connected to the bottom of the mixing tank 49; a bevel gear 54 is fixedly connected to one end of the stirring rod 53; the bevel gear 52 and the bevel gear 54 mesh with each other; a stirring plate 55 is engaged on the circumferential surface of the stirring rod 53; and a locking sleeve 56 is engaged on the circumferential surface of the stirring rod 53. In some examples, the circumferential surface of the stirring rod 53 is provided with a number of slots, which are arranged in a circumferential array on the circumferential surface of the stirring rod 53. This provides multiple installation positions for the stirring plates 55, making it easy to adjust the number and spacing of the stirring plates 55 according to the material characteristics and stirring requirements, thereby enhancing the adaptability of the stirring mechanism 5.

[0034] Several mixing plates 55 are arranged in a circumferential array on the circumferential surface of the mixing rod 53 to increase the contact area with the material, improve the uniformity of mixing, and avoid local accumulation of material. The rotation radius of the mixing plates 55 is smaller than the inner wall size of the mixing box 49, which can prevent the mixing plates 55 from rubbing and colliding with the inner wall of the mixing box 49, reduce the wear of parts, and at the same time reserve space for material flow, so that the material can be fully circulated and turned during the mixing process, ensuring more thorough mixing, and ensuring the stable operation of the mixing mechanism 5 and the quality of material mixing.

[0035] The sides of bevel gear 1 52 and bevel gear 2 54 are provided with spoke holes. The number of spoke holes is set to a certain extent and they are arranged in a circumferential array on the sides of bevel gear 1 52 and bevel gear 2 54. While ensuring the structural strength of the bevel gears, the inertia of the bevel gears during rotation is reduced, making the transmission lighter and more flexible, while reducing the load on the drive device and saving energy.

[0036] The rotation radius of the spiral plate 45 is smaller than the inner wall radius of the feed box 42. One end of the transmission pipe 48 is located on the rotation trajectory of the spiral plate 45, which can prevent the spiral plate 45 from rubbing or colliding with the inner wall of the feed box 42 during rotation, reduce component wear, ensure the stable operation of the spiral transmission structure, realize the precise transition of materials from the feed box 42 to the subsequent processing stage, reduce material spillage or accumulation, and improve the continuity of the overall process.

[0037] For example, such as Figures 1-5 As shown, the motor 43 drives the rotating shaft 44 to rotate, which in turn drives the bevel gear 52 at its end to rotate. Because the bevel gear 52 meshes with the bevel gear 54 at the top of the stirring rod 53, which is rotatably connected to the bottom of the mixing box 49, the horizontal rotational motion is converted into vertical rotation, causing the stirring rod 53 to rotate accordingly. The multiple stirring plates 55, which are engaged with the circumference of the stirring rod 53, rotate with the stirring rod 53 inside the mixing box 49 under the fixing of the locking sleeve 56. By utilizing the fact that the rotation radius is smaller than the inner wall size of the mixing box 49, the stirring plates 55 fully mix the material fed into the transmission pipe 48, thus completing the mixing operation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
