[0060] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0061] like Figures 1-16 As shown, the present invention provides:

[0062] A horizontal planetary mixer that is convenient for controlling the feeding amount includes a frame 10 and a mixing drum 20 installed in the frame 10, a feeding unit 30 is assembled on the mixing drum 20, a discharge port is provided at the bottom of the mixing drum 20, and an opening and closing door is provided at the end of the discharge port;

[0063] The feeding unit 30 includes a discharge box 31 fixedly connected to the mixing drum 20. A conical feeding hopper 32 is detachably fixed to the discharge box 31. A discharge rod 33 for controlling the feeding amount is rotatably connected to the discharge box 31. The discharge rod 33 is provided with a plurality of discharge channels 34 distributed in an annular array. The plurality of discharge channels 34 have different inner diameters. A guide seat 35 for guiding the material into the discharge channels 34 is clamped on the top of the inner wall of the discharge box 31.

[0064] The other end of the discharge rod 33 passing through the discharge box 31 is provided with a positioning sleeve, the bottom end of the positioning sleeve is fixed to the mixing barrel 20, and a knob bolt is threaded through the positioning sleeve for fixing the position of the discharge rod 33 after rotation;

[0065] Specifically, the discharge rod 33 can be rotated through the rotating part at one end thereof, and the different discharge channels 34 can be turned to a state connected with the top inlet of the guide seat 35, so that the amount of material passing through can be controlled, and the amount of material added during the mixing process can be controlled. At the same time, when no material is needed, the discharge rod 33 can be rotated to a position where the discharge channel 34 is not connected with the top inlet of the guide seat 35. It is worth noting that after the rotation, in order to prevent the material from driving the discharge rod 33 to shift during the discharge process, the knob bolt needs to be tightened to fix the discharge rod 33 in the positioning sleeve.

[0066] like Figure 1 、 Figure 2 、 Figure 6 and Figure 8As shown, a planetary stirring unit 40 is rotatably connected in the mixing drum 20, and the planetary stirring unit 40 includes a rotating disk 41 rotatably connected to both ends of the mixing drum 20, and a central shaft 42 is rotatably connected to the middle of the inner sides of the two rotating disks 41. A third bearing seat is fixed to the other end of the frame 10, and the central shaft 42 passes through one end of the other rotating disk 41 and is inserted into the third bearing seat. Two groups of symmetrically arranged spiral ribbon stirring blades 43 are assembled on the central shaft 42. A plurality of perforated shifting plates 45 for shifting large particle materials deposited at the bottom to the upper side are rotatably connected at the edges of the inner sides of the two rotating disks 41. The central shaft 42 and the perforated shifting plate 45 pass through one end of one of the rotating disks 41 and are jointly equipped with a planetary gear assembly 46.

[0067] One end of the frame 10 is equipped with a first motor 50 connected to the central shaft 42. The outer surface of the first motor 50 is covered with a protective cover. When the central shaft 42 rotates with the spiral stirring blade 43 driven by the first motor 50, the planetary gear assembly 46 drives the perforated paddle 45 to rotate together, which can move the large particles deposited at the bottom of the mixing drum 20 due to gravity to the top of the whole material for uniform mixing.

[0068] like Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 15 As shown, the planetary gear assembly 46 includes a retaining ring 461 fixed to one end of the mixing barrel 20, a gear ring 462 is detachably fixed to the inner wall of the retaining ring 461, a gear disc 463 is fixedly sleeved on the end of the central shaft 42 connected to the first motor 50, a perforated shift plate 45 passes through one end of one of the rotating disks 41, and a gear 464 meshing with the gear ring 462 and the gear disc 463 is inserted through a slot 465, and one end of the multiple gears 464 is equipped with a switching assembly 44 for controlling the disengagement of the gear ring 462 and the gear disc 463;

[0069] Specifically, after the middle shaft 42 is rotated by the drive of the first motor 50, the gear disc 463 thereon rotates together. During the rotation of the gear disc 463, the gear ring 462, which remains in a fixed position, is cooperated to make the gear 464 rotate at the same time during the revolution around the gear disc 463, thereby making the large particles of material deposited at the bottom of the mixing drum 20 be able to be moved upward by the rotating and self-rotating perforated plate 45 in cooperation with the perforated plate 45. It is worth noting that in the initial state, the holes on the surface of the perforated plate 45 allow large particles of material to pass through smoothly. In this state, only a small amount of large particles of material can be moved upward through the rest of the surface of the perforated plate 45 during the rotation, and then mixed with the rest of the material, thereby improving the mixing uniformity.

[0070] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 10 、 Figure 12 and Figure 16 As shown, the switching assembly 44 includes a connecting frame 441 fixed to the end of the gear 464, and a holding disk 442 is rotatably connected to the outer side of the connecting frame 441. A first electric push rod 443 is assembled on the outer side of the holding disk 442. The first electric push rod 443 is fixed to the inner top wall of the protective cover. At least one first limiting hole is opened on the gear 464. A first insertion rod 444 that adapts to the first limiting hole is fixed on the outer wall of one of the rotating disks 41, so that the gear 464 cannot rotate after the first insertion rod 444 is inserted into the first limiting hole.

[0071] A second insertion hole is formed on the toothed disc 463, and a second insertion rod 445 adapted to the second insertion hole is fixed on the inner side of the connecting frame 441, so that after the second insertion rod 445 is inserted into the second insertion hole, the connecting frame 441 rotates along with the toothed disc 463;

[0072] Specifically, when it is necessary to stop the perforated paddle plate 45 from rotating on its own and only rotate with the central shaft 42, after adjusting the perforated paddle plate 45 to the required angle, the first electric push rod 443 is started to make the holding disk 442 push the connecting frame 441 to move inward, so that the second insertion rod 445 is inserted into the second insertion hole on the toothed disk 463, so that the connecting frame 441 can rotate with the toothed disk 463, and the connecting frame 441 will push the gear 464 to move inward during the inward movement, disengaging from the toothed disk 463 and the gear ring 462, and being inserted into the first insertion rod 444 through the first limiting hole, so that the position of the gear 464 and the perforated paddle plate 45 is fixed. At this time, when the central shaft 42 rotates, the toothed disk 463 will drive the connecting frame 441 and the perforated paddle plate 45 to rotate together, so that the perforated paddle plate 45 can push the large particles of material at a fixed depth to the top for re-mixing to improve the mixing effect.

[0073] like Figure 2 、 Figure 4 、 Figure 9 and Figure 16 As shown, a perforated baffle plate 47 is slidably mounted on one side of the perforated dial plate 45 through a sliding groove, and a dial plate groove 48 is provided at the top and bottom of the outer wall of the perforated dial plate 45. An adjustment unit 60 for adjusting the position of the perforated baffle plate 47 is installed at the top of the inner wall of the mixing drum 20;

[0074] The adjustment unit 60 includes a shaft 61 rotatably connected to the top of the inner wall of the mixing drum 20. A paddle lever 62 is fixed to the shaft 61 and is adapted to fit into the paddle slot 48. A second motor 63 is mounted on the top of the outer wall of the mixing drum 20 via a mounting bracket. One end of the paddle lever 62 extends through the mixing drum 20 and is connected to the output end of the second motor 63.

[0075] A plurality of mounting holes are provided on one side wall of the slideway, and arc-surface clamping posts 49 are connected to the mounting holes via springs. A plurality of clamping slots adapted to the arc-surface clamping posts 49 are provided on both sides of the perforated shielding plate 47, so that the position of the perforated shielding plate 47 can be fixed after displacement driven by the plate-moving rod 62.

[0076] Specifically, when it is necessary to block the holes at different positions on the surface of the perforated paddle plate 45 so that the perforated paddle plate 45 can paddle large particle materials at different layers to the upper side for mixing during the rotation process, the shaft 61 is rotated by starting the second motor 63, so that the paddle plate rod 62 rotates to different angles, so that when the perforated paddle plate 45 rotates to the upper side, the paddle plate rod 62 gradually enters the paddle plate groove 48, thereby pushing the perforated shielding plate 47 to move downward, and the angles and positions of movement are different, so that the holes at different positions of the perforated paddle plate 45 are partially blocked, making the range of the holes smaller, thereby making it impossible for large particle materials at the corresponding layer to pass through, and thus most of the large particle materials at the corresponding layer can be paddled to the upper side for re-mixing, effectively improving the mixing efficiency and mixing effect;

[0077] It is worth noting that when the perforated plate 45 is in a rotatable state, when the hole at the bottom is partially blocked in its vertical state, as it continues to revolve and rotate, when it rotates to the bottom, it will appear inverted, that is, rotated 180 degrees from the original state, and the blocked hole is turned upward. In this state, large particles at the bottom layer can easily pass through the holes on the surface of the perforated plate 45, while large particles at the upper layer cannot pass through. It is worth noting that the smallest range after the holes are blocked can also allow small particles to pass through, and small particles can only be pushed upward by the part outside the holes.

[0078] like Figure 7 and Figure 11 As shown, a second electric push rod 36 is assembled on one side of the conical feeding hopper 32, and a first bearing seat is fixed to one end of the second electric push rod 36. A communicating vessel 37 is inserted in the first bearing seat, and one end of the communicating vessel 37 is sleeved on the end of the discharging rod 33 passing through the discharging box 31. A key slot is provided at the end of the discharging rod 33 passing through the discharging box 31, and a key block adapted to the key slot is fixed on one side of the inner wall of the communicating vessel 37, so that the communicating vessel 37 can rotate together with the discharging rod 33. A connecting shaft 38 is installed on the mounting frame through the second bearing seat, and one end of the connecting shaft 38 and one end of the middle shaft 42 passing through the other rotating disk 41 are fixedly sleeved with pulleys, and a transmission belt 39 is engaged and connected to the two pulleys.

[0079] The end of the connecting shaft 38 that penetrates into the communicating vessel 37 is fixed with a first friction sleeve, and the other side of the inner wall of the communicating vessel 37 is fixed with a second friction sleeve 310, so that the communicating vessel 37 can rotate with the connecting shaft 38. The inner cavity of the communicating vessel 37 is tapered as a whole.

[0080] Specifically, when the position of the discharge rod 33 is not fixed, during the rotation of the central shaft 42, the second electric push rod 36 pushes the communicating vessel 37 toward the connecting shaft 38. When the second friction sleeve 310 is engaged with the first friction sleeve, the communicating vessel 37 is able to rotate along with the connecting shaft 38 under the action of friction. At this time, when the central shaft 42 rotates, the connecting shaft 38 is driven to rotate together through the transmission belt 39, thereby causing the discharge rod 33 to rotate together, so that different discharge channels 34 are rotated to be connected with the top inlet of the guide seat 35, so that the feeding amount is intermittently changed.

[0081] Specifically, when the horizontal planetary mixer is easy to control the amount of feed, the following steps are performed during operation / use:

[0082] 1. Preparation stage:

[0083] Ensure that the mixer is in the stopped state and check whether all components are firmly installed, especially the feeding unit 30, the planetary mixing unit 40 and the transmission components. Then, according to the type of materials to be mixed and the mixing requirements, adjust the discharge rod 33 in the feeding unit 30, select the appropriate discharge channel 34, and fix its position with the knob bolt. Check and confirm the cleanliness of the mixing drum 20 and clean it if necessary.

[0084] 2. Start the mixer:

[0085] Start the first motor 50, so that the central shaft 42 drives the spiral stirring blade 43 to start rotating. At the same time, the planetary gear assembly 46 also starts working, and the perforated paddle 45 rotates while revolving. During the mixing process, the mixing status of the materials in the mixing drum 20 is observed through the observation port to ensure that the materials are evenly stirred.

[0086] 3. Control the amount of feed:

[0087] When the feeding amount needs to be adjusted, the discharge channel 34 can be adjusted by manually rotating the discharge rod 33, and then fixed after adjustment. When the feeding amount needs to be dynamically adjusted, it is necessary to ensure that the discharge rod 33 is not fixed by the knob bolt, and then start the second electric push rod 36 to push the communicating vessel 37 to move toward the connecting shaft 38 until the second friction sleeve 310 is in close contact with the first friction sleeve. At this time, the central shaft 42 drives the connecting shaft 38 to rotate through the transmission belt 39, thereby causing the communicating vessel 37 and the discharge rod 33 to rotate together. By rotating the discharge rod 33, different discharge channels 34 are connected to change the amount of material passing through, thereby controlling the feeding amount.

[0088] 4. Adjust the working state of the perforated dial plate 45:

[0089] According to the mixing requirements, the working state of the perforated dial plate 45 is adjusted by the first electric push rod 443. When the perforated dial plate 45 is required to rotate, the gear 464 is kept in meshing state with the gear ring 462 and the gear disc 463.

[0090] When the perforated shift plate 45 is required to rotate only in accordance with the central axis 42 without rotating on its own, the first electric push rod 443 is activated to move the connecting frame 441 inward, and the second insertion rod 445 is inserted into the second insertion hole on the gear plate 463. At the same time, the gear 464 is fixed to the first insertion rod 444 through the first limiting hole, thereby achieving a fixed angle rotation of the perforated shift plate 45.

[0091] 5. Adjust the perforated shielding plate 47:

[0092] As needed, the second motor 63 is started to rotate the shaft 61, thereby driving the plate lever 62 to rotate to different angles. When the perforated plate 45 rotates upward, the plate lever 62 gradually enters the plate slot 48, pushing the perforated shielding plate 47 to move in the slide slot, shielding the holes at different positions on the perforated plate 45.

[0093] By adjusting the position of the perforated shielding plate 47, the perforated paddle plate 45 can be controlled to paddle different layers of large particle materials to the top for mixing during the rotation process;

[0094] 6. Mixing completion and unloading:

[0095] When the materials are evenly mixed, turn off the first motor 50 and the second motor 63, stop the mixing and adjustment operations, open the opening and closing door at the bottom of the mixing drum 20, discharge the mixed materials from the discharge port, and finally clean the mixing drum 20 and the feeding unit 30 to prepare for the next mixing operation.

[0096] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
