[0042] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0045] In the description of this embodiment, the terms "upper", "lower", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] like Figure 1-Figure 7 As shown, the embodiment of the utility model provides a material mixer, including a mixer 1, a hopper 2, a conveying device 3 and a feeding speed measuring component 4. The mixer 1 includes a housing 11 with a mixing chamber disposed therein. A plurality of hoppers 2 are disposed on the upper portion of the housing 11 and are spaced apart along the circumference of the housing 11. The conveying device 3 is disposed one by one corresponding to the hopper 2, and is used to deliver the material in the corresponding hopper 2 into the mixing chamber. The feeding speed measuring components 4 are arranged one by one corresponding to the hoppers 2. Each feeding speed measuring component 4 is arranged on the shell 11 and is located below the corresponding hopper 2. The feeding speed measuring components 4 include a first discharge enclosure 41 provided with a chute. The first discharge enclosure 41 has a first working position and a second working position. When the first discharge enclosure 41 is located at the first working position, the material sent into the mixing chamber by the conveying device 3 flows out of the mixer 1 through the chute on the corresponding first discharge enclosure 41. When the first discharge enclosure 41 is located at the second working position, the material sent into the mixing chamber by the conveying device 3 enters the lower part of the mixing chamber.

[0047] In the mixer provided in the present embodiment, the conveying device 3 conveys the material in the corresponding hopper 2 to the mixing chamber, and each hopper 2 is correspondingly provided with a feeding speed measuring component 4. When it is necessary to measure whether the actual feeding speed of a certain material deviates from the set speed, it is only necessary to adjust the first discharge enclosure 41 of the corresponding feeding speed measuring component 4 from the second working position to the first working position, so that the material fed into the mixing chamber by the conveying device 3 flows out of the mixer 1 through the chute on the corresponding first discharge enclosure 41. By measuring the volume or weight of the material flowing out of the mixer 1 within a certain period of time, it is possible to conveniently determine whether the feeding speed of the material is consistent with the set speed. For example, the material flowing out of the mixer 1 within a certain period of time can be received by a tray, and the weight of the material received by the tray during this period of time can be weighed by an electronic scale. The expected feeding weight during this period of time is calculated according to the feeding speed set for the material, and the weighed weight is compared with the expected feeding weight to determine whether the feeding speed of the material is consistent with the set speed. If they do not match, it means that the material conveying capacity of the conveying device 3 has changed, and the mixer needs to be maintained and adjusted. If they match, it means that there is no problem with the material conveying capacity of the conveying device 3, and the mixer can continue to be used normally. When there is no need to measure whether there is a deviation between the actual feeding speed of the material and the set speed, it is only necessary to keep the first discharge enclosure 41 of the feeding speed measuring component 4 in the second working position, and the conveying device 3 can feed the material to the lower part of the mixing chamber normally. Multiple hoppers 2 are arranged on the upper part of the shell 11, and are arranged at intervals along the circumference of the shell 11, so that the materials entering the mixing chamber from each hopper 2 begin to mix during the fall. The falling process is also a mixing process, which can fully mix various materials with large specific gravity differences or different sizes and shapes. Only a small amount of stirring is needed later, or even no stirring is needed to complete the mixing, reducing the generation of static electricity and dust.

[0048] Furthermore, if Figure 3-Figure 7As shown, the feeding speed measuring component 4 also includes a second discharging panel 42. A first discharging port corresponding to the feeding speed measuring component 4 is provided on the side wall of the shell 11. The second discharging panel 42 is provided outside the shell 11, surrounds the corresponding first discharging port, and extends in a direction away from the shell 11. The first discharging panel 41 is slidably provided in the second discharging panel 42, and can slide between the first working position and the second working position through the first discharging port. The second discharging panel 42 is provided to enable the first discharging panel 41 to slide between the first working position and the second working position. Specifically, the second discharging panel 42 is tilted downward to facilitate the material entering the feeding speed measuring component 4 to slide out of the shell 11. A fourth discharge port is provided at one end of the first discharge baffle plate 41 away from the shell body 11, and a fifth discharge port is provided at one end of the second discharge baffle plate 42 away from the shell body 11. When the first discharge baffle plate 41 is in the first working position, materials entering the chute of the first discharge baffle plate 41 from the hopper 2 enter the second discharge baffle plate 42 through the fourth discharge port, and finally leave the feeding speed measuring component 4 through the fifth discharge port.

[0049] Furthermore, if Figure 3-Figure 7 As shown, the feeding speed measuring assembly 4 also includes an operating rod 43, and a strip hole 421 extending along the extension direction of the second discharging enclosure 42 is provided on the second discharging enclosure 42. One end of the operating rod 43 is connected to the first discharging enclosure 41, and the other end passes through the strip hole 421 and is exposed to the second discharging enclosure 42. The operating rod 43 can slide along the strip hole 421, and the first discharging enclosure 41 can be easily controlled to slide relative to the second discharging enclosure 42 through the end of the operating rod 43 exposed to the second discharging enclosure 42. When the operating rod 43 abuts against one end of the strip hole 421 close to the housing 11, the first discharging enclosure 41 is in the first working position, and when the operating rod 43 abuts against one end of the strip hole 421 outside the housing 11, the first discharging enclosure 41 is in the second working position.

[0050] Furthermore, if Figure 3-Figure 7As shown, the feeding speed measuring assembly 4 also includes a fastener 44. A threaded hole is provided at a position corresponding to the strip hole 421 on the first discharging enclosure 41. One end of the operating rod 43 is inserted into the threaded hole and screwed to the first discharging enclosure 41. The fastener 44 is fixedly provided at one end of the operating rod 43 exposed to the second discharging enclosure 42. Rotating the fastener 44 can drive the operating rod 43 to rotate relative to the first discharging enclosure 41, so that the fastener 44 abuts against the second discharging enclosure 42. When it is necessary to fix the first discharging enclosure 41, the operating rod 43 is rotated clockwise relative to the first discharging enclosure 41 by screwing the fastener 44. At this time, the operating rod 43 moves into the first discharging enclosure 41. When the fastener 44 abuts against the outer wall of the second discharging enclosure 42, the relative position between the first discharging enclosure 41 and the second discharging enclosure 42 is fixed by the friction between the fastener 44 and the second discharging enclosure 42. When the first material discharging enclosure 41 needs to be moved, the fastener 44 is twisted counterclockwise to disengage the fastener 44 from the outer wall of the second material discharging enclosure 42 .

[0051] Furthermore, if Figure 3-Figure 7 As shown, both sides of the second discharge enclosure 42 are provided with strip holes 421, and the operating rod 43 and the fastener 44 are arranged one by one corresponding to the strip holes 421. The operator can hold the two fasteners 44 with both hands to move the first discharge enclosure 41, thereby facilitating the operation of the operator.

[0052] Furthermore, if Figure 3-Figure 7 As shown, the first discharge enclosure 41 includes a first bottom plate 411 and two first side plates 412 . The first bottom plate 411 and the two first side plates 412 are arranged to form a slide groove, and a threaded hole is arranged on the first side plate 412 .

[0053] Furthermore, if Figure 3-Figure 7 As shown, a first material baffle plate 413 is provided at one end of the first discharging enclosure 41 close to the shell 11, and the first material baffle plate 413 blocks the end surface of the chute close to the shell 11 to prevent the material in the hopper 2 that enters the mixing chamber from falling into the chute and then escaping from the end of the chute that extends into the shell 11.

[0054] Furthermore, when the first discharging enclosure 41 is located at the first working position, the first baffle plate 413 blocks the first discharging port, thereby preventing the material from entering the feeding speed measuring component 4 from the first discharging port when the first discharging enclosure 41 is located at the first working position.

[0055] Alternatively, if Figure 3 As shown, a hopper feed port 24 is provided on the top surface of the hopper 2 , and the hopper feed port 24 is used to add materials into the hopper 2 .

[0056] Alternatively, if Figure 1-Figure 3As shown, each hopper 2 is provided with a manual cleaning valve 21, and the manual cleaning valve 21 includes a third discharge enclosure 211 and a second baffle plate 212. A second discharge port is provided at the lower part of each hopper 2, and the third discharge enclosure 211 is provided on the outer wall of the corresponding hopper 2 and surrounds the second discharge port. A discharge port is provided at one end of the third discharge enclosure 211 away from the second discharge port, and a second baffle plate 212 is provided at the discharge port for opening and closing the discharge port. When the type of material in a hopper 2 needs to be replaced, the discharge port can be opened through the second baffle plate 212, so that the material in the hopper 2 flows out of the hopper 2 through the second discharge port and the discharge port, thereby cleaning the material in the hopper 2. Specifically, the second baffle plate 212 is rotatably provided on the third discharge enclosure 211, and the discharge port is opened and closed by manually rotating the second baffle plate 212.

[0057] Alternatively, if Figure 1-Figure 3 As shown, each hopper 2 is provided with a first material level sensor 22, which is used to detect whether the material level in the corresponding hopper 2 is lower than the first preset position. When the material in the hopper 2 is lower than the first preset position, it means that the material in the hopper 2 is insufficient and the material needs to be replenished in time.

[0058] Alternatively, if Figure 1-Figure 3 As shown, a first observation window 23 is provided on the side wall of each hopper 2, so that the operator can observe the situation in the hopper 2. It can be understood by those skilled in the art that the first observation window 23 should be made of a transparent material, such as transparent polycarbonate (PC plastic).

[0059] Alternatively, if Figure 1 , Figure 8 and Fig. 9 As shown, the conveying device 3 includes a first motor 31 and a conveying screw 32. The first motor 31 is disposed on the housing 11. One end of the conveying screw 32 is connected to the first motor 31, and the other end extends into the housing 11. The conveying screw 32 is driven to rotate by the first motor 31, and the material at the bottom of the hopper 2 is pushed into the mixing chamber by the rotation of the conveying screw 32. The first motor 31 is a brushless motor, which has low maintenance times and low maintenance costs.

[0060] Furthermore, if Figure 1 and Figure 8As shown, the conveying device 3 also includes a feeding barrel 33, one end of which is fixedly connected to the first electrode 31, and the other end extends to the mixing chamber. The conveying screw 32 is arranged in the feeding barrel 33, and a feeding barrel feed port 331 is arranged at the top of the feeding barrel 33. The material in the hopper 2 can enter the feeding barrel 33 through the feeding barrel feed port 331, and a feeding barrel discharge port 332 is arranged at the bottom of the end of the feeding barrel 33 extending into the mixing chamber. When the first discharge enclosure 41 is located at the first working position, the chute of the first discharge enclosure 41 is located directly below the feeding barrel discharge port 332. The material entering the feeding barrel 33 through the feeding barrel feed port 331 moves toward the end of the feeding barrel 33 extending into the mixing chamber under the push of the conveying screw 32, and finally enters the mixing chamber through the feeding barrel discharge port 332. When it is necessary to measure the feeding speed of a certain material into the mixing chamber, the first discharge enclosure 41 is slid to the first working position. At this time, the discharge port 332 of the feeding barrel faces the slide groove of the first discharge enclosure 41, so that the materials entering the mixing chamber through the discharge port 332 of the feeding barrel can enter the slide groove of the first discharge enclosure 41, and then flow out to the outside of the mixer 1 through the first discharge enclosure 41 and the second discharge enclosure 42.

[0061] Alternatively, if Figure 1 and Figure 2 As shown, the mixer 1 also includes a stirring assembly 12 disposed at the bottom of the housing 11, and the stirring assembly 12 includes a second motor 121 and a stirring screw 122. The second motor 121 is disposed on the housing 11. The stirring screw 122 is disposed at the lower part of the mixing chamber and is in transmission connection with the second motor 121. The stirring screw 122 is driven to rotate by the second motor 121, and the materials entering the mixing chamber from each hopper 2 are stirred by the rotation of the stirring screw 122 to further mix them evenly. The second motor 121 is a brushless motor, which has less maintenance times and low maintenance costs.

[0062] Alternatively, if Figure 1 and Figure 2 As shown, the mixer 1 further includes a second material level sensor 13 disposed on the housing 11. The second material level sensor 13 is used to monitor whether the material level in the mixing chamber is higher than a second preset position. When the material level in the mixing chamber is higher than the second preset position, it indicates that material accumulation has occurred in the mixing chamber, and the machine should be stopped for processing.

[0063] Alternatively, if Figure 1 and Figure 2As shown, the mixer also includes a control cabinet 5, in which a control module is arranged. The control module is used to control the operation of various parts of the mixer. The first motor 31, the second motor 121, the first material level sensor 22 and the second hopper 2 sensor are all connected to the control module for communication. When the material level in the mixing chamber is higher than the second preset position and the material level in the hopper 2 is lower than the first preset position, the control module issues an alarm. When the material level in the mixing chamber is higher than the second preset position, the control module controls the mixer to stop. The control module stores a material formula. When the mixer is mixing materials, the control module can automatically control the operation of each conveying device 3 according to the material formula, so that each conveying device 3 automatically delivers materials to the mixing chamber according to the ratio of various materials in the material formula.

[0064] Alternatively, if Figure 1 and Figure 2 As shown, a second observation window 112 is provided on the side of the housing 11, so that the operator can observe the situation in the mixing chamber. It can be understood by those skilled in the art that the second observation window 112 should be made of a transparent material, such as transparent polycarbonate (PC plastic). In this embodiment, the second material level sensor 13 is provided outside the second observation window 112, and the second material level sensor 13 is a capacitive material level sensor. It can be understood by those skilled in the art that the capacitive material level sensor can monitor the material level in the housing 11 through the polycarbonate observation window.

[0065] Alternatively, if Figure 2 As shown, a third discharge port 111 is provided on the bottom end surface of the shell 11 , and the materials mixed in the mixing chamber leave the mixer through the third discharge port 111 and enter into subsequent processing steps.

[0066] Optionally, the mixer in this embodiment, the parts in contact with the materials are made of SUS201 stainless steel, and the various parts are connected in a modular and detachable manner, which is convenient for disassembly and assembly, and easy to clean and replace.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
