[0002] Prior art continuous mixers achieve continuous mixing by installing a level meter on the mixer drum and adjusting the discharge door opening angle based on the material volume, as exemplified by patent CN 219114411 U. Alternatively, patent CN 201525083 U employs a load cell installed below the mixer drum to adjust the discharge process based on the material weight, achieving continuous mixing. However, patent CN 219114411 U fails to consider the impact of the material volume within the mixer drum on the mixing process and thus fails to provide overload protection. While patent CN 201525083 U allows for weight-based adjustment of the discharge door opening angle, it fails to consider the impact of the material volume within the mixer drum on the continuous mixing process. Consequently, prior art suffers from a technical problem in which the discharge door opening and rotation speed cannot be controlled based on the material volume and weight within the mixer drum to achieve continuous feeding and continuous mixing, rendering it ineffective for mixing high-throughput materials.

[0061] In some exemplary embodiments, the discharge door 8 includes:

[0062] The discharge door cover 401 is located below the discharge port of the rotary cylinder 7, and the bottom of the door cover is provided with a discharge door shaft;

[0063] The motor compartment 409 is located below the cover of the discharge door 8 and is provided with a driver therein, the output end of which is connected to the discharge door shaft. The driver is provided with a speed sensor and establishes communication with the control device to collect the rotation speed and control the rotation speed of the discharge door 8 according to the instructions of the control device;

[0064] In some exemplary embodiments, the discharge door 8 further includes:

[0065] The angle flip shaft is installed at one end of the motor compartment 409 of the unloading door 8. The angle flip shaft is provided with an angle sensor and establishes communication with the control device.

[0068] In specific applications, when the discharge door 8 is closed, the adjustment driver rotates at the same speed as the cylinder; when the discharge door 8 is opened at a small angle, the driver controls the discharge door 8 to rotate rapidly, and the mixed material falls through the discharge door 8 to the discharge door cover 401 and is thrown off and scattered again; when the discharge door 8 is opened at a large angle, the driver controls the discharge door cover 401 to rotate rapidly around the discharge door axis, so that the mixer can discharge quickly. The rapid rotation of the discharge door cover 401 can clean up accumulated and adhered materials.

[0069] In some exemplary embodiments, a vibrator 10 is further included. The vibrator 10 is located on the weighing base assembly 5 and vibrates to remove accumulated materials near the discharge port during operation.

[0070] The working process of an embodiment of the utility model mixer is described below with reference to the accompanying drawings:

[0071] During the feeding process, the discharge gate 8 closes, and the rotating drum 7 sends the unmixed material to the rotor 6 for mixing. The driver rotates at the same speed as the rotating drum 7. When the material reaches a certain volume, the discharge gate 8 moves horizontally a distance, forming an outlet with the rotating drum 7, and enters the continuous mixing and unloading process.

[0072] During the continuous mixing and unloading process, the level meter 11 detects the material level inside the rotating cylinder 7 in real time, obtains the current material volume and sends a material volume signal; the weighing base assembly 5 detects the material weight of the rotating cylinder 7 in real time and sends a material weight signal; the control device receives the material volume signal measured by the level meter 11 and the material weight signal measured by the weighing base assembly 5, and judges whether the obtained material volume and material weight have reached the maximum value of their corresponding values. According to the judgment result, the control device sends a rotation control instruction and an angle flip control instruction to the unloading door 8, respectively controlling the rotation speed of the unloading door 8 and adjusting the opening and closing angle of the unloading door 8, and adjusting the unloading speed. When the feed amount and the discharge amount are balanced, the effect of continuous mixing and continuous unloading can be achieved.

[0073] When the volume and weight of the material in the rotating cylinder 7 have not reached the maximum value, the control device controls the discharge door 8 to open at a small angle during the stirring process, and adjusts the driver to make the discharge door 8 rotate quickly, which can achieve a continuous stirring effect, reduce the unloading steps, and carry out stirring and unloading at the same time, greatly improving the throughput per unit time.

[0074] Until the volume of the material in the rotating cylinder 7 reaches the maximum value and / or the weight of the material reaches the maximum value, the control device controls the discharge door 8 to open at a large angle during the mixing process, and adjusts the driver to make the discharge door 8 rotate rapidly around the discharge door axis, so that the mixer can quickly discharge the material, which can reduce the accumulation of material on the surface of the discharge door 8 during the unloading process. The adhered material can also be thrown off and scattered through the rapid rotation of the discharge door 8, thereby improving the uniformity of material falling.

[0075] Through the description of multiple embodiments of the mixer of the present invention, it can be seen that the mixer of the present invention has at least one or more of the following advantages:

[0076] 1. The level meter detection swing arm extends into the rotary cylinder, and the material level is pushed to rotate and the tension spring is rotated through the material liquid level. It can detect the material level, prevent the material volume from overloading, control the maximum volume of the mixing material, and protect the mixer.

[0077] 2. The weighing base assembly is installed under the mixer's rotating cylinder. Through the horizontal tie rod, longitudinal tie rod and its tie rod seat, the weight of the material inside the mixer cylinder can be weighed in real time to ensure the stability of the weighing, thereby accurately controlling the weight of the material entering and leaving the mixer, making the material ratio more accurate.

[0078] 3. The control device controls the rotation speed of the discharge door and adjusts the opening and closing size of the discharge door according to the material weight detected by the weighing base and the material volume detected by the level meter, thereby adjusting the volume and weight of the material inside the rotary cylinder, keeping the volume and weight of the material inside the rotary cylinder constant, and achieving the effect of continuous feeding and continuous unloading.

[0079] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0080] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention.
