[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. During the mixing process, it also increases the contact surface area of ​​the materials to promote chemical reactions and accelerate physical changes. Commonly used mixers are divided into four categories: gas and low-viscosity liquid mixers, medium- and high-viscosity liquid and paste mixers, and powder and granular solid material mixers. The moving parts of a mechanical agitator shear the liquid or powder as they rotate. The liquid is also sheared as it flows through the walls and various fixed components installed in the container. This shearing action causes many local eddies to diffuse, further mixing the liquid.

[0003] In the prior art, for those distribution hoppers used to hold materials mixed in a mixer, there is a problem: every time the distribution hopper needs to be loaded with materials, the hopper cover must be manually removed. This operation method undoubtedly makes the entire operation process cumbersome and complicated, increasing the time and labor costs of operation, and may also affect the improvement of work efficiency to a certain extent, and there is a certain risk of contamination.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0023] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0024] like Figures 1 to 5 As shown, an embodiment of the present invention includes an elevator 1, a mixer 2 and a material distribution hopper 3. The mixer 2 is connected to the elevator 1 and can be lifted up and down under the drive of the elevator 1. It also includes a cover removal mechanism 4. The cover removal mechanism 4 includes a fixed bracket fixedly connected to the elevator 1, a lifting control mechanism 42 connected to the fixed bracket, and a vacuum suction cup 41 connected to the lifting control mechanism 42.

[0025] The vacuum suction cup 41 includes a connecting piece 411, a suction cup body 412 and a tube body 413. One end of the tube body 413 extends into the connecting piece 411 as an air inlet end 421, and the other end is connected to the vacuum pump outside the connecting piece 411 as an air extraction end 422. The connecting piece 411 is connected to the suction cup body 412. A through hole 415 is provided at the top of the suction cup body 412. A chamber 416 communicating with the air inlet end 421 and the through hole 415 is provided in the connecting piece 411. A sphere 417 is provided in the chamber 416. The sphere 417 is arranged below the air inlet end 421 and abuts against the top of the suction cup body 412.

[0026] It can be understood that when the vacuum pump evacuates the suction cup body 412, the gas located in the suction cup body 412 will flow out of the suction end 421 from the air inlet end 421 through the gap between the sphere 417 and the suction cup body 412. When the vacuum pump stops working, the sphere 417 will drop down due to the action of gravity and abut against the top of the suction cup body 412, so that the gas will not enter the suction cup body 412, thereby avoiding the adsorption force between the suction cup body 412 and the hopper cover 31 being affected by air leakage at the suction end 422.

[0027] The chamber 416 is provided with a valve 418 to prevent backflow. The valve 418 is arranged between the ball 417 and the air inlet end. The valve 418 can only allow gas to pass upward.

[0028] It is understandable that the valve 418 and the ball 417 both inhibit gas from entering the suction cup body 412 to avoid reducing the suction force between the suction cup body 412 and the hopper cover.

[0029] A filling cavity 419 is formed between the tube body 413 extending into the connecting piece 411 and the connecting piece 411 , and a filling material is provided in the filling cavity 419 .

[0030] The tube body 413 is an L-shaped structure including a vertical tube body and a horizontal tube body. A channel for connecting the horizontal tube body and the vertical tube body is provided on the side of the connecting piece 411.

[0031] It includes a vent hole 43 and a piston 44 . The vent hole 43 is communicated with the suction cup body 412 , and the piston 44 is adapted to the vent hole 43 .

[0032] It is understandable that when the cap removal mechanism 4 is to place the cap, by pulling out the piston 44 in the vent hole 43, the pressure of the suction cup body 412 and the pressure in the chamber 416 can be made consistent with the atmospheric pressure, thereby achieving cap placement.

[0033] The suction cup body 412 is a telescopic suction cup. The suction cup body 412 includes several layers of suction cups arranged in sequence from top to bottom, the top of the suction cup at the lower layer is flush with the bottom of the suction cup at the upper layer, and the bottoms and tops of two adjacent suction cups are connected by a connecting portion.

[0034] A protrusion 420 is provided at the top of the connecting member 411 , and the protrusion 420 is connected to the lifting control mechanism 42 .

[0035] The lifting control mechanism 42 includes a telescopic component 423 and a first drive component 424. The telescopic component 423 is connected to the protrusion 420. The first drive component 424 is connected to the telescopic component 423 and can drive the telescopic component 423 to move between the initial position and the cover removal position 51.

[0036] A sliding assembly 45 is provided on one side of the elevator 1, and is connected to the cover removing mechanism 4 through the sliding assembly 45. The sliding assembly 45 includes a second driving assembly and a slide rail 451. The cover removing mechanism 4 is connected to the slide rail 451 and has a waiting position 52 closer to the elevator 1 and a cover removing position 51 farther from the elevator 1. The second driving assembly is connected to the slide rail 451 and can drive the slide rail to move between the waiting position 52 and the cover removing position 51.

[0037] It can be understood that the second drive component on the sliding component 45 and the first drive component 424 in the lifting control mechanism 42 can both be cylinders. The lifting control mechanism 42 can control the vacuum suction cup 41 to descend from the initial position to the cover removal position 51 to remove the hopper cover 31 on the distribution hopper 3. The second drive component and the slide rail 451 can slide the vacuum suction cup 41 from the cover removal position 51 to the waiting position 52, which is convenient for the user to move the distribution hopper 3 to the discharge port of the mixer 2.

[0038] The invention comprises a zeroing device 32 and a weighing device 33. The zeroing device 32 is placed just below the cover taking position 51, and the zeroing device 32 is used to zero the weight of the distribution hopper 3. The weighing device 33 is set just below the discharge port of the mixer 2. The weighing device 32 is used to weigh the weight of the distribution hopper 3. The working process of this embodiment is as follows: when the mixer 2 starts to discharge, the distribution hopper 3 is first transported to the zeroing device 32, and the sliding assembly 45 is used to move the vacuum suction cup 4 The material in the distribution hopper 3 is then transported from the waiting position 51 to directly above the zeroing device 32. The lifting control mechanism 42 then lowers the vacuum suction cup 41 from its initial position to the cover removal position 51, where it contacts the hopper cover 31 at the top of the distribution hopper 3. The suction cup body 412 on the vacuum suction cup 41 then lifts the hopper cover 31, completing the suction operation. The distribution hopper 3 is then transported from the zeroing device 32 to the weighing device 33. The mixer 2's discharge port is simultaneously opened to allow material to be discharged, and the weighing device 33 performs real-time weighing on the distribution hopper 3. When the weight of the distribution hopper 3 reaches the specified value, the mixer 2's discharge port is closed. Once all the material in the distribution hopper 3 has been removed, the lifting control mechanism 42 and the sliding assembly 45 coordinate to place the hopper cover 31 on top of the distribution hopper 3, completing the entire process of cover removal, distribution, and placement.
