[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 16 As shown, the present invention provides: A horizontal planetary mixer that is convenient for controlling the amount of feeding, comprising a frame 10 and a mixing drum 20 installed in the frame 10, the mixing drum 20 is equipped with a feeding unit 30, the mixing drum 20 is provided with a discharge port at the bottom, and an opening and closing door is provided at the end of the discharge port; The feeding unit 30 includes a discharge box 31 fixedly connected to the mixing barrel 20, a conical feeding hopper 32 is detachably fixed on the discharge box 31, a discharge rod 33 for controlling the feeding amount is rotatably connected inside the discharge box 31, a plurality of discharge channels 34 distributed in a circular array are opened on the discharge rod 33, and the inner diameters of the plurality of discharge channels 34 are different. A guide seat 35 for guiding materials into the discharge channels 34 is clamped on the top of the inner wall of the discharge box 31; The other end of the discharging rod 33 passing through the discharging box 31 is sleeved 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 discharging rod 33 after rotation; Specifically, the discharge rod 33 can be rotated through the rotating part at one end thereof, and different discharge channels 34 can be turned to a state of being 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 addition is required, 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.

[0021] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As 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, and 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, and two groups of symmetrically arranged spiral ribbon stirring blades 43 are mounted on the central shaft 42, and multiple 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, and a planetary gear assembly 46 is mounted on the central shaft 42 and the perforated shifting plate 45 passing through one end of one of the rotating disks 41; One end of the frame 10 is equipped with a first motor 50 connected to the central axis 42, and the outer surface of the first motor 50 is covered with a protective cover. When the central axis 42 is driven by the first motor 50 to rotate with the spiral stirring blade 43, the perforated paddle plate 45 is driven to rotate through the planetary gear assembly 46, so that large particles deposited at the bottom of the mixing barrel 20 due to gravity can be moved to the top of the whole material for uniform mixing.

[0022] like Figure 2 , Figure 5 , Figure 6 , Figure 8 and Fig.15As 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 on the inner wall of the retaining ring 461, a fixed sleeve is provided with a toothed disc 463 at one end of the central shaft 42 connected to the first motor 50, a perforated shifting 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 toothed disc 463 is inserted through a slot 465, and one end of the plurality of gears 464 is equipped with a switching assembly 44 for controlling the gears 464 to disengage from the gear ring 462 and the toothed disc 463; Specifically, after the middle shaft 42 is driven by the first motor 50 to rotate, the toothed disc 463 thereon rotates together, and during the rotation of the toothed disc 463, the gear ring 462, which remains in a fixed position, is cooperated to make the gear 464 rotate while revolving around the toothed disc 463, so that the large particles deposited at the bottom of the mixing barrel 20 can be moved upward by the revolving and rotating perforated plate 45 in cooperation with the perforated plate 45 around the spiral stirring blade 43. It is worth noting that in the initial state, the holes on the surface of the perforated plate 45 allow large particles to pass smoothly. In this state, only a small part of the large particles 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 materials, so that the mixing uniformity is improved; like Figure 2 , Figure 3 , Figure 4 , Fig.10 , Fig.12 and Fig.16 As shown, the switching assembly 44 includes a connecting frame 441 fixed to the end of the gear 464, the outer side of the connecting frame 441 is rotatably connected to a retaining disk 442, the outer side of the retaining disk 442 is equipped with a first electric push rod 443, the first electric push rod 443 is fixed to the inner top wall of the protective cover, and at least one first limiting hole is opened on the gear 464, and a first plug rod 444 adapted 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 plug rod 444 is inserted into the first limiting hole; A second insertion hole is provided 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 together with the toothed disc 463; Specifically, when it is necessary to stop the perforated paddle plate 45 from rotating on its own and only rotate with the central axis 42, after adjusting the perforated paddle plate 45 to the required angle, start the first electric push rod 443 to make the retaining disk 442 push the connecting frame 441 to move inward, so that the second plug rod 445 is inserted into the second plug 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, disengage the toothed disk 463 and the gear ring 462, and be connected to the first plug 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 axis 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.

[0023] like Figure 2 , Figure 4 , Fig. 9 and Fig.16 As shown, a perforated shielding plate 47 is slidably mounted on one side of the perforated dial plate 45 by opening a slide groove, a dialing plate groove 48 is opened at the top and bottom of the outer wall of the perforated dial plate 45, and an adjustment unit 60 for adjusting the position of the perforated shielding plate 47 is installed at the top of the inner wall of the mixing barrel 20; The adjustment unit 60 includes a shaft 61 rotatably connected to the top of the inner wall of the mixing cylinder 20, a paddle rod 62 adapted to the paddle groove 48 is fixed to the shaft 61, a second motor 63 is mounted on the top of the outer wall of the mixing cylinder 20 through a mounting frame, and one end of the paddle rod 62 passes through the mixing cylinder 20 and is connected to the output end of the second motor 63; A plurality of mounting holes are provided on one side wall of the slide slot, and a curved clamping column 49 is connected to the mounting hole through a spring. A plurality of clamping grooves matching the curved clamping column 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 lever 62. 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 of 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 is rotated to different angles, so that when the perforated paddle plate 45 is rotated 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, so that the range of the holes becomes smaller, so that the large particle materials of the corresponding layers cannot pass through, and most of the large particle materials of the corresponding layers can be paddled to the upper side for re-mixing, thereby effectively improving the mixing efficiency and mixing effect; It is worth noting that when the perforated plate 45 is in a state where it can rotate, when the hole at the bottom is partially blocked in the vertical state, as it continues to revolve and rotate, when it rotates to the bottom, it will appear inverted, that is, rotated 180° from the original state, and the blocked hole is turned to the top. 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 hole is blocked can also allow small particles to pass through, and small particles can only be pushed to the top by the part other than the hole. like Figure 7 and Fig.11 As shown, a second electric push rod 36 is installed on one side of the conical feeding hopper 32, and a first bearing seat is fixed on 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 one end of the discharging rod 33 passing through the discharging box 31. A key slot is provided on one end of the discharging rod 33 passing through the discharging box 31, and a key block matching 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 another rotating disk 41 are fixedly sleeved with pulleys, and a transmission belt 39 is meshed and connected to the two pulleys. 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, and the inner cavity of the communicating vessel 37 is tapered as a whole; Specifically, when the position of the discharge rod 33 is not fixed, during the rotation of the middle 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 can rotate along with the connecting shaft 38 under the action of friction. At this time, when the middle shaft 42 rotates, the connecting shaft 38 is driven to rotate together through the transmission belt 39, so that the discharge rod 33 rotates 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.

[0024] Specifically, when the horizontal planetary mixer which is easy to control the feeding amount is working / using: 1. Preparation stage: Ensure that the mixer is in the shutdown state, and check whether all components are firmly installed, especially the feeding unit 30, the planetary mixing unit 40 and the transmission components, etc. 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 a suitable discharge channel 34, and fix its position with the knob bolt, and check and confirm the cleanliness of the mixing barrel 20, and clean it if necessary; 2. Start the mixer: Start the first motor 50, so that the central shaft 42 drives the spiral stirring blade 43 to start rotating, and the planetary gear assembly 46 also starts working, and the perforated paddle 45 rotates while revolving. During the mixing process, the mixing condition of the materials in the mixing barrel 20 is observed through the observation port to ensure that the materials are evenly stirred; 3. Control the amount of feed: When the feeding amount needs to be adjusted, the discharging rod 33 can be manually rotated to adjust the discharging channel 34, and then fixed after adjustment. When the feeding amount needs to be dynamically adjusted, it is necessary to ensure that the discharging 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 middle shaft 42 drives the connecting shaft 38 to rotate through the transmission belt 39, thereby making the communicating vessel 37 and the discharging rod 33 rotate together, and the different discharging channels 34 are connected by rotating the discharging rod 33 to change the amount of material passing through, thereby controlling the feeding amount; 4. Adjust the working state of the perforated dial plate 45: According to the mixing requirements, the working state of the perforated plate 45 is adjusted by the first electric push rod 443. When the perforated plate 45 is required to rotate, the gear 464 is kept in meshing state with the gear ring 462 and the gear disc 463. When the plate with holes 45 is required to rotate only following the central axis 42 without rotating itself, the first electric push rod 443 is started to move the connecting frame 441 inward, and the second plug rod 445 is inserted into the second plug hole on the gear plate 463. At the same time, the gear 464 is fixed to the first plug rod 444 through the first limiting hole, so that the plate with holes 45 can rotate at a fixed angle. 5. Adjust the perforated shielding plate 47: 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 to the upper side, the plate lever 62 gradually enters the plate slot 48, pushing the perforated shielding plate 47 to move in the slide slot to shield the holes at different positions on the perforated plate 45. 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 upper side for mixing during the rotation process; 6. Mixing completion and unloading: When the materials are mixed evenly, turn off the first motor 50 and the second motor 63, stop the mixing and adjusting 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.
