Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, and in particular to a mixing machine. Background Technology

[0002] A mixing machine, also known as a motion mixer, is a high-efficiency mixing device designed specifically for powdery and granular materials. It is widely used in the food, pharmaceutical, and chemical industries. A one-dimensional mixing machine consists of a horizontally placed cylinder that rotates around a horizontal axis. The materials inside the mixing cylinder move up and down alternately under the friction of the inner wall and gravity, thus achieving material mixing. Chinese invention patent application CN105080382A provides a mixing machine that uses a stirring shaft and stirring blades inside the cylinder to fully mix the materials under the pushing force of the stirring blades. However, when mixing some materials, such as metal particles, excessive extrusion pressure from the stirring blades can cause electrical sparks, potentially leading to explosions and other safety issues. Therefore, a shaft-type stirrer cannot be used. However, if the shaft-type stirrer is omitted, the materials remain relatively stationary along the axial direction of the cylinder because the inner wall is straight, preventing axial movement and resulting in uneven mixing, which affects the mixing effect. Utility Model Content

[0003] The purpose of this invention is to provide a mixing machine to solve the problems existing in the prior art. While improving safety, it enables the material to move axially in the cylinder, making the material mix more uniform and thus improving the mixing effect.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] This utility model provides a mixing machine, including a cylinder and a driving mechanism for driving the cylinder to rotate. A discharge port communicating with the interior of the cylinder is provided at one end of the cylinder. A driving surface is provided on the inner wall of the cylinder. The distance between the driving surface and the axis of the cylinder gradually increases or decreases from the side away from the discharge port to the side closer to the discharge port. When the cylinder rotates around its axis, the driving surface can drive the material to move along the axial direction of the cylinder.

[0006] In one embodiment, at least two driving surfaces are provided, and the driving surfaces have at least two different tilt angles relative to the axis of the cylinder.

[0007] In one embodiment, the driving surface is arranged in a spiral shape around the axis of the cylinder, and the end of the spiral inclined surface has a smooth transition with the discharge port.

[0008] In one embodiment, blades are protruding from the side wall of the cylinder, and the blades extend along the axial direction of the cylinder. When the cylinder rotates about its axis, the blades can drive the material to move circumferentially along the cylinder.

[0009] In one embodiment, a vibrator is provided on the outer wall of the cylinder, and the vibrator is capable of causing the side wall of the cylinder to vibrate.

[0010] In one embodiment, the inner wall surface of the cylinder near the discharge port is tapered, gradually narrowing towards the discharge port's cross-sectional area, and a discharge cover capable of closing or opening the discharge port is provided at the discharge port.

[0011] In one embodiment, an auxiliary discharge device is also included, which is disposed at the end of the cylinder. The auxiliary discharge device enables the cylinder to switch between a first state and a second state. In the first state, the cylinder is horizontal, and in the second state, the cylinder tilts downward from the end away from the discharge port to the end closer to the discharge port.

[0012] In one embodiment, a cleaning port is provided at the end of the cylinder away from the discharge port, and a cleaning cover is provided at the cleaning port that can close or open the cleaning port.

[0013] In one embodiment, the system further includes a base, which is fixed in position relative to the ground, and the cylinder, the drive mechanism, and the auxiliary discharge device are all mounted on the base.

[0014] In one embodiment, a shock-absorbing device is also included, which is disposed between the base and the ground.

[0015] The present invention achieves the following technical advantages over the prior art:

[0016] The mixer provided by this utility model has a driving surface on the inner wall of the cylinder. The distance from the driving surface to the cylinder axis gradually changes from the side away from the discharge port to the side closer to the discharge port. When the cylinder rotates around its axis, the material moves along the circumference of the cylinder while the driving surface can drive the material to move along the axial direction of the cylinder. The extrusion force of the driving surface on the material is small. While improving safety, it makes the movement trajectory of the material more complex, thereby making the material more uniformly mixed and improving the mixing effect of the material.

[0017] Furthermore, by providing at least two driving surfaces with at least two different inclination angles relative to the axis of the cylinder, the materials can move at different speeds along the axial direction of the cylinder. At the junction of the two driving surfaces, materials with different speeds can collide with each other, thereby making the material mixing more uniform. Attached Figure Description

Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The purpose of this invention is to provide a mixing machine that solves the problems existing in the prior art. While avoiding safety issues such as explosions, it allows the material to move axially in the cylinder, making the material mix more uniform and thus improving the mixing effect.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides a mixing machine, such as Figures 1-2As shown, the device includes a cylinder 1 and a drive mechanism 2 that drives the cylinder to rotate. A discharge port 11 communicating with the inside of the cylinder is provided at one end of the cylinder. A drive surface 3 is provided on the inner wall of the cylinder 1. The distance from the drive surface 3 to the axis of the cylinder 1 gradually increases or decreases from the side away from the discharge port 11 to the side closer to the discharge port 11. When the cylinder 1 rotates around its axis, the material moves along the circumference of the cylinder 1 while the drive surface 3 can drive the material to move along the axial direction of the cylinder 1. The extrusion force of the drive surface on the material is small. While improving safety, it makes the movement trajectory of the material more complex, thereby making the material more uniformly mixed and improving the mixing effect of the material.

[0026] In some embodiments of this utility model, such as Figure 2 As shown, at least two driving surfaces 3 are provided, and the driving surfaces 3 have at least two different inclination angles relative to the axis of the cylinder 1, so that the materials have different speeds of movement along the axial direction of the cylinder 1. At the junction of the two driving surfaces 3, materials with different speeds of movement can collide with each other, thereby making the material mixing more uniform.

[0027] In some embodiments of this utility model, such as Figure 2 As shown, the distance from the drive surface 3 to the axis of the cylinder 1 gradually decreases from the side away from the discharge port 11 to the side closer to the discharge port 11, so that the material moves along the cylinder 1 toward the discharge port 11, so as to facilitate the discharge after the mixing is completed.

[0028] In some embodiments of this utility model, the driving surface 3 is arranged in a spiral shape around the axis of the cylinder 1, and there is a smooth transition between the end of the spiral inclined surface and the discharge port 11, so that the material is discharged from the discharge port 11 after moving in a spiral shape along the driving surface 3.

[0029] In some embodiments of this utility model, such as Figure 2 As shown, blades 4 are protruding from the side wall of the cylinder 1. The blades 4 extend along the axial direction of the cylinder 1. When the cylinder 1 rotates around its axis, the blades 4 can drive the material to move in the circumferential direction, making the range of material movement in the circumferential direction larger. The material is lifted and falls under the drive of the blades 4. Combined with the material moving in the circumferential direction of the cylinder 1 under the action of the driving surface 3, the mixing uniformity of the material is further improved.

[0030] In some embodiments of this utility model, a guide plate is also provided inside the cylinder 1 near the discharge port 11. The guide plate is spirally arranged around the axis of the cylinder. The distance from the guide plate to the axis of the cylinder 1 gradually decreases from the side away from the discharge port 11 to the side near the discharge port 11. The guide plate can accelerate the discharge of material from the discharge port 11.

[0031] In some embodiments of this utility model, such as Figure 1As shown, a vibrator 5 is installed on the outer wall of the cylinder 1. The vibrator 5 causes the side wall of the mixing machine cylinder 1 to generate high-frequency micro-vibrations, which breaks the adhesion between the material and the wall surface, causing the material attached to the wall surface to fall off, thereby achieving the purpose of preventing the material from sticking to the wall.

[0032] In some embodiments of this utility model, such as Figure 2 As shown, the inner wall of the cylinder 1 near the discharge port 11 is a cone shape that gradually narrows towards the discharge port 11. A discharge cover 12 is provided at the discharge port 11 to close or open the discharge port 11. The cone structure allows the material to gradually move towards the discharge port 11 while concentrating the material towards the center during rotation, enhancing axial movement, accelerating mixing efficiency, and eliminating dead corners in traditional flat-end designs. This prevents material from stagnating during the mixing process, ensuring uniform mixing and thorough discharge, and reducing waste.

[0033] In some embodiments of this utility model, such as Figure 1 As shown, a feed inlet 15 communicating with the cylinder is also provided on the side wall of the cylinder 1, and a feed cover 16 that can close or open the feed inlet 15 is provided at the feed inlet 15.

[0034] In some embodiments of this utility model, when the cylinder 2 stops rotating after the mixing is completed, the discharge port 11 is opened to discharge the material. After the discharge is completed, the discharge port 11 is closed, and the feed port 15 is opened to feed the material. After the feeding is completed, the feed port 15 is closed, and the drive mechanism 2 is started to drive the cylinder 2 to rotate to mix the material.

[0035] In some embodiments of this utility model, such as Figure 1 As shown, the mixer also includes an auxiliary discharge device 6, which is located at the end of the cylinder 1. The auxiliary discharge device 6 enables the cylinder 1 to switch between a first state and a second state. In the first state, the cylinder 1 is horizontal and rotates around its axis under the drive of the drive mechanism 2 to mix the material. In the second state, the cylinder 1 stops rotating and tilts downward from the end away from the discharge port 11 to the end near the discharge port 11, so that the end of the cylinder 1 away from the discharge port 11 is high and the end near the discharge port 11 is low, so that the material in the cylinder 1 flows out from the discharge port 11 under the action of gravity.

[0036] In some embodiments of this utility model, such as Figure 1 As shown, the auxiliary discharge device 6 includes a lifting frame 61 and a support frame 62. The lifting frame 61 is located at the end of the cylinder 1 away from the discharge port 11 and can extend to lift the cylinder 1 in the second state. Meanwhile, the support frame 62 at the end of the cylinder 1 near the discharge port 11 is used to support the conical outer wall of the cylinder 1 to prevent the end near the discharge port 11 from falling when the lifting frame 61 lifts the cylinder 1 away from the discharge port 11.

[0037] In some embodiments of this utility model, such as Figure 1 As shown, a cleaning port 13 is provided at the end of the cylinder 1 away from the discharge port 11. A cleaning cover 14 is provided at the cleaning port 13, which can be closed or opened. When the cylinder stops rotating after mixing, the cleaning cover 14 can be opened to facilitate the thorough cleaning of residual materials and prevent cross-contamination. The cleaning cover is closed before the cylinder starts rotating again for the next mixing.

[0038] In some embodiments of this utility model, the inner wall of the cylinder 1 is made of stainless steel and is polished to make the inner wall of the cylinder 1 sufficiently smooth, thereby preventing materials from adhering to the inner wall of the cylinder 1.

[0039] In some embodiments of this utility model, such as Figure 1 As shown, the mixer also includes a base 7, which is fixed relative to the ground. The cylinder 1, the drive mechanism 2, and the auxiliary discharge device 6 are all mounted on the base 7. The stability of the cylinder 1, the drive mechanism 2, and the auxiliary discharge device 6 during mixing and discharge is ensured by mounting the base 7.

[0040] In some embodiments of this utility model, such as Figure 1 As shown, the mixer also includes a shock-absorbing buffer device 8, which is located between the base 7 and the ground. It can effectively absorb and buffer the vibration energy generated during the operation of the equipment, extend the service life of the equipment, and reduce the vibration and noise generated during the operation of the equipment, thus improving the working environment.

[0041] In some embodiments of this utility model, the mixer also includes a control system. The control system is signal-connected to the drive device to control the drive device to drive the cylinder 1 to rotate around its axis. The control system is signal-connected to the vibrator 5 to control the vibrator 5 to vibrate. The control system is signal-connected to the lifting frame 61 to control the lifting frame 61 to extend and retract, so that the cylinder 1 switches between a first state and a second state.

[0042] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
