Abstract
Description
Technical Field
[0001] This invention belongs to the field of production technology, and in particular relates to a gyratory mixing machine. Background Technology
[0002] In the food, condiment, feed, chemical, and pharmaceutical industries, mixing machines are widely used for the uniform mixing of powders, granules, or viscous materials. Currently, most rotary mixing equipment on the market uses a fixed frame to support a mixing drum that rotates around its own axis. The drum's rotation causes the material to tumble, thus achieving mixing. However, it typically only has a single rotational function; the material mainly relies on gravity and centrifugal force to circumferentially tumble within the drum. While this motion mode can achieve mixing to some extent, there is almost no active flow of material in the axial direction, easily forming "dead zones" at both ends of the drum, leading to uneven mixing. Furthermore, for high-viscosity, easily agglomerated, or materials with significant density differences, simple rotation is insufficient to effectively break up agglomerates and promote dispersion, often requiring longer mixing times and impacting production efficiency. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a composite motion oscillating mixer.
[0004] The objective of this invention can be achieved through the following technical solution: a gyratory mixer, comprising:
[0005] frame;
[0006] A mixing drum has a mixing chamber with openings at both ends along the axis. The mixing drum is rotatably connected to the frame. Both ends of the mixing drum are detachably equipped with caps that can seal the openings.
[0007] A support frame is rotatably connected to the machine frame, and a swing drive is provided between the support frame and the machine frame, so that the mixing cylinder can swing along its axial direction.
[0008] In the aforementioned oscillating mixer, two sets of abutment parts are rotatably arranged on the frame. Each set of abutment parts includes at least two abutment wheels. The two sets of abutment parts are respectively arranged at both ends of the mixing cylinder and abut against the outer surface of the mixing cylinder. The axis of the abutment wheel is parallel to the axis of the mixing cylinder.
[0009] In the aforementioned oscillating mixer, abutment rings are fixedly provided at both ends of the outer surface of the mixing cylinder. The abutment rings extend radially along the mixing cylinder. Two sets of limiting parts are rotatably provided on the frame. Each set of limiting parts includes at least two limiting wheels rotatably provided on the frame. The two sets of abutment parts are provided at both ends of the mixing cylinder and abut against the abutment rings. The axis of the limiting wheels is perpendicular to the axis of the mixing cylinder.
[0010] In the aforementioned oscillating mixer, a transmission rack is fixedly arranged radially on the outer surface of the mixing cylinder, a drive unit is fixedly arranged on the frame, and a drive gear is driven at the output end of the drive unit to mesh with the transmission rack.
[0011] In the aforementioned type of oscillating mixer, a mounting frame is hinged to the frame, and the cover is rotatably mounted on the mounting frame. When the cover is on the opening, the cover can rotate synchronously with the mixing cylinder.
[0012] In the aforementioned type of oscillating mixer, a tensioning part is hinged to the frame, and the drive shaft of the tensioning part can move linearly and is hinged to the cover.
[0013] In the aforementioned type of oscillating mixer, a oscillating part is hinged to the support frame, and the drive shaft of the oscillating part can move linearly and is hinged to one end of the frame.
[0014] In the aforementioned type of oscillating mixer, the support frame includes two support parts that are opposite to each other and spaced apart. The support parts are hinged to the frame, and the frame of the support parts is triangular.
[0015] In the aforementioned type of oscillating mixer, a reinforcing part is fixedly provided on the inner side of the support part.
[0016] In the aforementioned type of oscillating mixer, several stirring sections are fixedly installed on the inner wall of the mixing cylinder.
[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: the mixing drum rotates while periodically oscillating. This combined motion significantly enhances the tumbling, convection, and diffusion effects of materials within the mixing chamber, improving mixing uniformity and efficiency. After mixing is complete, the equipment can be stopped, and the material can be quickly unloaded by opening the cap at either end. Attached Figure Description

Detailed Implementation
[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0025] like Figures 1-4 As shown, a gyratory mixing machine is provided, comprising a frame 100, a mixing cylinder 200, and a support frame 300. The mixing cylinder 200 is cylindrical, with a mixing chamber 201 extending through both ends. Each mixing chamber 201 has an opening at both ends, which are sealed by removable covers 202. The covers 202 can be quickly opened and closed, thereby achieving efficient material loading and unloading.
[0026] The mixing drum 200 is rotatably mounted on the frame 100, while the support frame 300 is rotatably connected to the frame 100 via a rotating shaft. A swing drive (e.g., a hydraulic cylinder, pneumatic cylinder, or electric push rod) is provided between the support frame 300 and the frame 100. This swing drive can drive the support frame 300 to swing back and forth relative to the frame 100, thereby causing the entire mixing drum 200 to swing along its own axis. Simultaneously, the mixing drum 200 can also be driven by an independent rotary drive device to rotate continuously around its own axis.
[0027] In actual use, first open the cover 202 and add the materials to be mixed into the mixing chamber 201 from one end; then tighten the sealing cover 202, and the mixing drum 200 rotates. At the same time, the oscillating drive is activated to make the mixing drum 200 oscillate periodically while rotating. This combined motion significantly enhances the tumbling, convection, and diffusion effects of the materials in the mixing chamber 201, improving the mixing uniformity and efficiency. After mixing is complete, stop the equipment and open the cover 202 at either end for quick unloading.
[0028] Furthermore, two sets of abutment portions are rotatably disposed on the frame 100, each set including at least two abutment wheels 101. The two sets of abutment portions are respectively arranged at both ends of the mixing cylinder 200 and roll in contact with the outer circumferential surface of the mixing cylinder 200. Each abutment wheel 101 is mounted in a support seat on the frame 100 via bearings, its own axis being parallel to the axis of the mixing cylinder 200, thereby providing stable support during the rotation and oscillation of the mixing cylinder 200. This effectively limits the radial runout of the mixing cylinder 200 while allowing it to rotate smoothly around its own axis.
[0029] Based on the aforementioned structure, abutment rings 203 are fixedly provided at both ends of the outer surface of the mixing cylinder 200. The abutment rings 203 extend outward along the radial direction of the mixing cylinder, forming a flange structure surrounding the outer circumference of the mixing cylinder. Correspondingly, two sets of limiting parts are rotatably provided on the frame 100. Each set of limiting parts includes at least two limiting wheels 102, which are rotatably mounted on a bracket on the frame 100 via bearings. The two sets of limiting parts are located at both ends of the mixing cylinder and roll in contact with the abutment rings 203 at the corresponding ends. Specifically, the axis of the limiting wheel 102 is perpendicular to the axis of the mixing cylinder, allowing the limiting wheel 102 to roll along the side of the abutment ring 203 (i.e., the end face of the abutment ring 203 facing the axial direction of the mixing cylinder), thereby effectively constraining the axial movement of the mixing cylinder. This prevents the mixing cylinder 200 from dislodging from its supported position due to inertia or gravity. Meanwhile, since the limit wheel 102 can rotate freely, it always maintains rolling friction with the abutment ring 203, which significantly reduces wear and running resistance.
[0030] Based on the aforementioned structure, a transmission rack 204 is fixedly provided on the outer surface of the mixing cylinder 200 along its radial direction. The transmission rack 204 can be arranged in a ring around the outer periphery of the mixing cylinder. Preferably, it is integrated into the abutment ring 203 at one end—that is, the outer edge of the abutment ring 203 is machined into a gear-shaped structure, which serves as both an abutment ring 203 for axial positioning and a transmission function, thus achieving a compact structure and functional integration.
[0031] Correspondingly, a drive unit 103 (such as a geared motor, servo motor, etc.) is fixedly mounted on the frame 100, and its output end is connected to a drive gear 104. The drive gear 104 meshes with the transmission rack 204 on the mixing drum, forming an external meshing gear transmission pair. When the drive unit 103 is started, the drive gear 104 drives the transmission rack 204, thereby driving the mixing drum to rotate around its own axis.
[0032] In this embodiment, a mounting bracket 105 is hinged to the frame 100, and the mounting bracket 105 is flip-connected to the frame 100 to facilitate overall opening or closing. The cover 202 is rotatably mounted on the mounting bracket 105 via bearings or bushings to ensure that the cover 202 can be accurately aligned and cover the opening at the end of the mixing cylinder 200.
[0033] When the cover 202 closes to the opening position of the mixing cylinder 200, the mounting frame 105 applies an axial pressing force to the end face of the mixing cylinder 200 under the action of an external drive (such as a cylinder). Under the pressing action of the mounting frame 105, the cover 202 is pressed and sealed to the end face of the mixing cylinder 200, and a reliable seal is achieved between the two through an annular sealing ring. Therefore, when the mixing cylinder 200 rotates around its own axis under the drive of the drive gear 104, the cover 202 rotates synchronously with the mixing cylinder 200 under the constraint of friction and pressing force, while the mounting frame 105 itself remains stationary (or only serves as a swing support).
[0034] Based on the aforementioned structure, a tensioning part 106 (e.g., a cylinder, hydraulic cylinder, or electric push rod) is hinged to the frame 100. The cylinder body or housing of the tensioning part 106 is rotatably connected to the frame 100 via a pin, allowing it to adapt to changes in the movement trajectory of the cover 202 during operation. The drive shaft (i.e., piston rod or push rod) of the tensioning part 106 can perform linear extension and retraction along its axial direction, and its end is hinged to the cover 202.
[0035] When it is necessary to close the end opening of the mixing drum 200, the drive shaft of the tensioning part 106 retracts (or extends, depending on the installation direction), pulling (or pushing) the cover 202 to rotate around its pivot on the mounting bracket 105, so that the cover 202 is pressed against the open end face of the mixing drum 200, achieving a seal under the auxiliary pressing action of the mounting bracket 105. At this time, as before, the cover 202 can rotate freely relative to the mounting bracket 105 in the pressed state and rotate synchronously with the mixing drum 200.
[0036] In this embodiment, the support frame 300 supports the mixing drum 200 and is rotatably connected to the frame 100 via a pivot, allowing the support frame 300 to reciprocate relative to the frame 100 about a horizontal pivot axis. To achieve this oscillation, a swinging part 301 (e.g., a hydraulic cylinder, pneumatic cylinder, or electric push rod) is hinged to the support frame 300. The cylinder body or housing of the swinging part 301 is hinged to one side of the support frame 300 via a pin, allowing it to adaptively adjust its angle as the support frame 300 swings. The drive shaft (i.e., piston rod or push rod) of the swinging part 301 can perform linear extension and retraction along its own axial direction, and its end is hinged to one end of the frame 100 via a pin. When the drive shaft extends or retracts, it pushes or pulls the support frame 300 to rotate about its connection pivot with the frame 100, thereby causing the entire mixing drum 200 to reciprocate along its axial direction.
[0037] In this embodiment, the support frame 300 is used to support the mixing cylinder 200, and its overall structure includes two opposing and spaced-apart support portions 302. These two support portions 302 are arranged parallel to each other on the outer sides of both ends of the mixing cylinder 200, together forming a stable support frame for the mixing cylinder 200. The frame of each support portion 302 has a triangular structure. This triangular frame has excellent geometric stability, preventing swaying or displacement.
[0038] To further enhance structural rigidity and load-bearing capacity, a reinforcing part 303 is fixedly provided on the inner side of each support part 302 (i.e., the side facing the other support part 302). This reinforcing part 303 is a rigid rod, profile, or plate-like component, with one end firmly connected to the upper or middle part of the support part 302, and the other end extending downwards and fixedly connected to the base frame 304. The base frame 304 is horizontally positioned at the bottom of the support frame 300, laterally connecting the lower ends of the two support parts 302 to form an integral chassis structure. Thus, the reinforcing part 303, the side of the support part 302, and a portion of the base frame 304 together constitute one or more auxiliary triangular structures. This multi-triangular layout significantly enhances the bending and torsional resistance of the support frame 300 under vertical loads (such as the mixing drum 200 and material gravity), dynamic inertial forces (such as the impact during swing start-stop), and torque, effectively suppressing deformation and vibration.
[0039] In this embodiment, the mixing cylinder 200 is a hollow cylindrical structure, with a mixing chamber 201 inside for containing and mixing materials. To enhance the agitation, dispersion and mixing effect of materials inside the cylinder, a plurality of stirring parts 205 are fixedly provided on the inner side wall of the mixing cylinder 200.
[0040] Each mixing section 205 includes several annularly spaced mixing plates. These plates protrude from the inner wall of the mixing cylinder 200 toward the center of the cavity and extend a certain length along the axial direction of the mixing cylinder 200. The mixing plates are not arranged in a straight line along the axial direction, but rather in a spiral or oblique arrangement along the outer circumference (i.e., the circumferential direction) of the mixing cylinder 200 during their extension, forming a structure similar to a "spiral guide vane" or "oblique blade." When the mixing cylinder 200 rotates under the drive of the drive gear 104, the mixing plates rotate together with the cylinder. Their inclined surfaces continuously apply axial thrust and circumferential shear force to the material, causing the material to not only tumble circumferentially but also reciprocate along the axial direction.
