Description

Technical Field

[0001] This utility model relates to the field of polyester material processing technology, and specifically to a polyester material processing mixing device. Background Technology

[0002] Polyester materials are a class of high molecular polymers characterized by ester bonds. They are formed by polycondensation reactions of polyols and polyacids. They have excellent mechanical properties, chemical stability and processability, and are one of the most widely used categories of modern polymer materials.

[0003] Application number CN202223384269.3 discloses an automatic polyester chip mixing device, including a support mechanism with a mixing mechanism on its upper part. The support mechanism includes a support column, with a fixed plate fixedly connected to the upper end of the support column. A mixing box is fixedly connected inside the fixed plate, and a discharge port is fixedly connected to the lower end of the mixing box. A sliding rod is fixedly connected to the upper end of the mixing box. This automatic polyester chip mixing device uses the support column to support two fixed plates, which respectively fix the mixing box externally from above and below. The mixing box then supports the sliding rods, and the upper ends of the three sliding rods are fixedly supported by a top plate. The top plate keeps the electric telescopic rod fixed. A lifting plate is sleeved on the outside of the sliding rods, allowing the lifting plate to slide stably up and down. This structure ensures a firm connection and stable support, which is beneficial for maintaining high efficiency and stability during mixing operation.

[0004] However, this device mixes materials through lifting motion, resulting in poor mixing uniformity. The lifting motion only allows for simple vertical displacement of the materials, leading to weak relative motion and a single trajectory, making it difficult to create complex cross-convection or shearing effects. For polyester chips with differences in density and particle size, stratification easily occurs due to gravity, with lighter materials floating to the top and heavier materials settling to the bottom. This results in localized uneven concentrations after mixing, failing to meet the uniformity requirements of high-precision production. Therefore, a polyester material processing and mixing device is proposed. Utility Model Content

[0005] The main objective of this invention is to provide a polyester material processing and mixing device that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A polyester material processing and mixing device includes a lifting plate, a turntable rotatably mounted inside the lifting plate, a bearing sleeved on the outer side of the turntable, a mechanical box fixedly mounted on the top of the turntable, and a spiral rod provided at the bottom of the mechanical box, wherein there are two spiral rods. The top of the lifting plate is fixedly connected to the top plate via connecting rods. Multiple connecting rods are provided. A second motor is fixedly installed on the top of the top plate. The output end of the second motor passes through the top plate and is fixedly connected to the top of the mechanical box.

[0007] By adopting the above technical solution, the screw rod, driven by the mechanical box and the second motor, synchronously revolves and rotates, forming a three-dimensional mixing trajectory. The revolution expands the mixing range, while the rotation generates strong shear force and promotes the upward and downward convection of materials. At the same time, the lifting plate realizes vertical lifting and lowering movement through the lead screw and guide rod, dynamically adjusting the working depth of the screw rod in the mixing box. The superposition of these three movements causes the materials to be subjected to strong disturbances in multiple directions in three-dimensional space, completely breaking the stratification phenomenon caused by density or particle size differences, and significantly improving the mixing uniformity and efficiency.

[0008] Specifically, the lifting plate is fastened to the top of the mixing box, the mixing box is fixedly installed on the top of the base, and the top of the base is fixedly installed with a first support plate and a second support plate.

[0009] By adopting the above technical solution, the mixing tank is fixed on the base as a container for holding the materials to be mixed. The lifting plate is fastened and installed on the top of the mixing tank to form a liftable cover structure, which ensures the basic enclosure of the mixing area. The first support plate and the second support plate are vertically fixed on the base and located on both sides of the mixing tank, providing vertical lifting support and guidance for the lifting plate and the entire mixing mechanism, such as the mechanical box and the screw rod above it.

[0010] Specifically, the first support plate and the second support plate are located on both sides of the mixing box, and each of the first support plate and the second support plate has an installation groove on the side that is close to each other.

[0011] By adopting the above technical solution, the mounting slots on the first support plate and the second support plate are respectively used to accommodate and install the core moving parts that drive the lifting plate to lift: the mounting slot of the first support plate is equipped with a lead screw and its transmission mechanism to provide lifting power; the mounting slot of the second support plate is equipped with a guide rod to provide stable lifting guidance.

[0012] Specifically, a lead screw is vertically rotatably installed inside the mounting groove of the first support plate, and a first connecting block is movably connected to the outside of the lead screw through a thread. One end of the first connecting block is fixedly connected to one side of the lifting plate.

[0013] Specifically, a first motor is fixedly installed on the top of the first support plate, and the output end of the first motor is fixedly connected to the top of the lead screw.

[0014] By adopting the above technical solution, when the first motor drives the lead screw to rotate in the mounting slot, the first connecting block, which is threadedly connected to the lead screw, is forced to move along the axial direction of the lead screw. Since the first connecting block is fixedly connected to one side of the lifting plate, the rotational motion of the lead screw is precisely converted into the vertical up-and-down motion of the lifting plate. This is the key driving link for adjusting the mixing depth of the screw in the mixing box.

[0015] Specifically, a guide rod is vertically fixedly installed inside the mounting groove of the second support plate, and a second connecting block is movably sleeved on the outside of the guide rod. One end of the second connecting block is fixedly connected to one side of the lifting plate.

[0016] By adopting the above technical solution, when the lifting plate moves up and down under the drive of the screw, the second connecting block fixed on the other side of the lifting plate slides along the guide rod that is vertically fixed in the mounting groove of the second support plate. The guide rod and the slidingly connected second connecting block work together to provide precise linear guidance and lateral support for the lifting plate's movement, preventing deviation or jamming during the lifting process and ensuring the smoothness and accuracy of the lifting movement.

[0017] The beneficial effects of this utility model are: The present invention discloses a polyester material processing mixing device in which the screw rod, driven by a mechanical box and a second motor, synchronously revolves and rotates to form a three-dimensional mixing trajectory. The revolution expands the mixing range, while the rotation generates strong shear force and promotes the material to flow vertically. At the same time, the lifting plate achieves vertical lifting and lowering movement through the lead screw and guide rod, dynamically adjusting the working depth of the screw rod in the mixing box. The superposition of these three movements causes the material to be subjected to strong disturbance in multiple directions in three-dimensional space, completely breaking the stratification phenomenon caused by density or particle size differences, and significantly improving the mixing uniformity and efficiency.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As one embodiment of this utility model, such as Figures 1-3 As shown, the polyester material processing and mixing device of this utility model includes a lifting plate 5, a turntable 12 is rotatably installed inside the lifting plate 5, a bearing 11 is sleeved on the outer side of the turntable 12, a mechanical box 2 is fixedly installed at the top of the turntable 12, and a spiral rod 9 is provided at the bottom of the mechanical box 2, and there are two spiral rods 9. The top end of the lifting plate 5 is fixedly connected to the top plate 16 via a connecting rod 15. Multiple connecting rods 15 are provided. A second motor 17 is fixedly installed on the top end of the top plate 16. The output end of the second motor 17 passes through the top plate 16 and is fixedly connected to the top end of the mechanical box 2.

[0022] When in use, the second motor 17 starts, and its output directly drives the mechanical box 2 to rotate. Since the mechanical box 2 is fixedly installed on the top of the turntable 12, and the turntable 12 is rotatably installed inside the lifting plate 5 through the bearing 11, the entire mechanical box 2, together with the two spiral rods 9 at its bottom, can stably revolve around the central axis of the lifting plate 5. At the same time, the drive device inside the mechanical box 2 will drive the two spiral rods 9 to rotate around their own axis.

[0023] It should be noted that the connecting rod 15 and the top plate 16 provide stable support for the second motor 17 and ensure the rigidity of the power transmission path; how the mechanical box 2 drives the screw rod 9 to rotate can be referred to in the existing mature technology mentioned in the background art.

[0024] The present invention also includes that the lifting plate 5 is fastened and installed on the top of the mixing box 8, the mixing box 8 is fixedly installed on the top of the base 18, and the top of the base 18 is fixedly installed with a first support plate 7 and a second support plate 13.

[0025] In use, the mixing tank 8 is fixed on the base 18 as a container to hold the materials to be mixed. The lifting plate 5 is fastened to the top of the mixing tank 8 to form a liftable cover structure, which ensures the basic enclosure of the mixing area. The first support plate 7 and the second support plate 13 are vertically fixed on the base 18 and located on both sides of the mixing tank 8, providing vertical lifting support and guidance for the lifting plate 5 and the entire mixing mechanism above it, such as the mechanical box 2 and the screw rod 9.

[0026] The present invention also includes that the first support plate 7 and the second support plate 13 are located on both sides of the mixing box 8, and that the first support plate 7 and the second support plate 13 are provided with mounting grooves 4 on the sides of the first support plate 7 and the second support plate 13 that are close to each other.

[0027] In use, the mounting slots 4 on the first support plate 7 and the second support plate 13 are respectively used to accommodate and install the core moving parts that drive the lifting plate 5 to lift: the screw 3 and its transmission mechanism are installed in the mounting slot 4 of the first support plate 7 to provide lifting power; the guide rod 14 is installed in the mounting slot 4 of the second support plate 13 to provide stable lifting guidance.

[0028] The present invention also includes a lead screw 3 vertically rotatably installed inside the mounting groove 4 of the first support plate 7, and a first connecting block 6 is threadedly connected to the outside of the lead screw 3, and one end of the first connecting block 6 is fixedly connected to one side of the lifting plate 5.

[0029] The present invention also includes a first motor 1 fixedly installed at the top of the first support plate 7, and the output end of the first motor 1 is fixedly connected to the top of the lead screw 3.

[0030] When in use, when the first motor 1 drives the lead screw 3 to rotate in the mounting groove 4, the first connecting block 6, which is threadedly connected to the lead screw 3, is forced to move along the axial direction of the lead screw 3. Since the first connecting block 6 is fixedly connected to one side of the lifting plate 5, the rotational motion of the lead screw 3 is precisely converted into the vertical up-and-down motion of the lifting plate 5. This is the key driving link for adjusting the mixing depth of the screw rod 9 in the mixing box 8.

[0031] The present invention also includes a guide rod 14 vertically fixedly installed inside the mounting groove 4 of the second support plate 13, and a second connecting block 10 movably sleeved on the outside of the guide rod 14, one end of the second connecting block 10 being fixedly connected to one side of the lifting plate 5.

[0032] When in use, when the lifting plate 5 moves up and down under the drive of the lead screw 3, the second connecting block 10 fixed on the other side of the lifting plate 5 slides along the guide rod 14 which is vertically fixed in the mounting groove 4 of the second support plate 13. The guide rod 14 and the slidingly sleeved second connecting block 10 work together to provide precise linear guidance and lateral support for the lifting movement of the lifting plate 5, preventing deviation or jamming during the lifting process, and ensuring the smoothness and accuracy of the lifting movement.

[0033] In use, when the first motor 1 starts, its output drives the lead screw 3 in the mounting groove 4 of the first support plate 7 to rotate. Since the first connecting block 6 is threadedly connected to the lead screw 3, and the second connecting block 10 slides on the guide rod 14 of the second support plate 13, the rotational motion of the lead screw 3 is converted into the vertical up-and-down motion of the lifting plate 5, thereby driving the mechanical box 2 and the two spiral rods 9 at the bottom to move up and down synchronously, allowing the two spiral rods 9 to mix the materials in the mixing box 8. The second motor 17 and the drive device inside the mechanical box 2 are started, and their output directly drives the mechanical box 2 to rotate. Since the mechanical box 2 is fixed at the top of the turntable 12, and the turntable 12 is installed in the lifting plate 5 through the bearing 11, the mechanical box 2 will drive the turntable 12 to rotate stably on the lifting plate 5, thereby causing the two spiral rods 9 at the bottom to perform synchronous circular revolution. At the same time, the internal structure of the mechanical box 2 can drive the two spiral rods 9 to perform their own rotation. Therefore, the spiral rods 9 form a "revolution + rotation" motion in the mixing box 8. The combined motion of the screw rod 9 can both push the bottom material upwards and generate shear force through rotation, breaking the gravitational separation trend of the material. This combined motion of the screw rod 9, combined with the up-and-down movement of the lifting plate 5, causes the material to be disturbed in multiple directions within the mixing box 8. The rotation of the screw rod 9 pushes the material up and down for convection, while its revolution expands the mixing range. Combined with the lifting motion to adjust the mixing depth, it greatly enhances the relative motion intensity and trajectory complexity between materials, effectively avoiding stratification caused by differences in density and particle size, improving mixing uniformity, and meeting the requirements of high-precision production for material uniformity.
