[0030] In the description of this embodiment, the terms "upper", "lower", "left", "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.
[0031] like Figure 1-Figure 3 As shown, this embodiment provides an automatic mixing device, which includes a first material discharge component 01, a second material discharge component 02, a mixing pipeline 03 and an adjusting component 04. The first material discharge component 01 and the second material discharge component 02 are both located above the mixing pipeline 03, and the first material discharge component 01 and the second material discharge component 02 are both connected to the mixing pipeline 03. The adjusting component 04 is arranged in the mixing pipeline 03, and the first material discharge component 01 is connected to the mixing pipeline 03 through the adjusting component 04. The adjusting component 04 includes a first material discharge tray 41 and a second material discharge tray 42 arranged relatively in a vertical direction. The first material discharge tray 41 is provided with a first material discharge hole 411, and the second material discharge tray 42 is provided with a second material discharge hole 421 , the relative position of the first feeding tray 41 and the second feeding tray 42 can be changed, thereby changing the relative position of the first feeding hole 411 and the second feeding hole 421. When the automatic mixing device is working, after injecting materials into the first feeding component 01 and the second feeding component 02, the materials in the second feeding component 02 continue to enter the mixing pipeline 03 under the action of gravity, and at the same time, the materials in the first feeding component 01 enter the mixing pipeline 03 through the first feeding hole 411 and the second feeding hole 421 in turn. The falling trajectories of the two materials intersect in the mixing pipeline 03, realizing real-time mixing, and there is no need to pre-mix the materials for storage and reuse, which reduces the labor cost of mixing various materials and inventory management, and saves inventory space. In addition, the adjustment component 04 can adjust the feeding speed of the materials in the first feeding component 01 into the mixing pipeline 03, thereby meeting the mixing of materials with different proportions. In addition, by changing the relative positions of the first discharge tray 41 and the second discharge tray 42, the overlap between the first discharge hole 411 and the second discharge hole 421 can be adjusted, so that the discharge speed of the material in the first discharge component 01 entering the mixing pipeline 03 can be accurately adjusted according to the formula ratio, thereby achieving precise control of the ratio of the two materials, ensuring the quality of the subsequently processed plastic products, enabling the adjustment component 04 to meet the precise adjustment of the discharge speed of small-proportion added materials, and simplifying the structure of the adjustment component 04.
[0032] Preferably, the automatic mixing device provided in this embodiment is particularly suitable for situations where the formula contains small proportions of added materials, such as masterbatch, additives or recycled materials with an addition ratio of ≤5%, but the application scenarios of the automatic mixing device are not limited to this, and it can also be used for mixing materials in other proportion formulas.
[0033] The utility model also provides a plastic product production line, including plastic production equipment and the above-mentioned automatic mixing device, the plastic production equipment is connected to the automatic mixing device, the materials are mixed in the mixing pipeline 03 and then enter the plastic production equipment, the plastic production equipment can process and shape the materials to obtain plastic products.
[0034] Specifically, in the present embodiment, the first discharge tray 41 and the second discharge tray 42 can rotate relative to each other around the rotation axis of the adjusting component 04, and the first discharge hole 411 and the second discharge hole 421 are arranged horizontally staggered with respect to the rotation axis. The adjusting component 04 also includes a rotating drive member 43, and the output end of the rotating drive member 43 is transmission-connected to one of the first discharge tray 41 and the second discharge tray 42. The rotating drive member 43 drives the first discharge tray 41 and the second discharge tray 42 to rotate relative to each other around the rotation axis of the adjusting component 04 to adjust the overlap between the first discharge hole 411 and the second discharge hole 421, thereby adjusting the discharge speed of the material passing through the first discharge hole 411 and the second discharge hole 421, thereby realizing automatic adjustment of different proportions of the two materials. Specifically, in the present embodiment, the first feed tray 41 is located above the second feed tray 42, the rotary drive member 43 is fixed on the lower surface of the second feed tray 42, the second feed tray 42 is fixedly installed in the mixing pipeline 03, and the output shaft of the rotary drive member 43 passes through the second feed tray 42 and is connected to the first feed tray 41 for driving the first feed tray 41 to rotate relative to the second feed tray 42 around the above-mentioned rotation axis. It should be noted that in the present embodiment, the rotary drive member 43 has no overlapping parts with the second feed hole 421 and the first feed hole 411 in the vertical direction, and will not block the normal feed work, thereby avoiding interference with the falling of the material. Optionally, the rotary drive member 43 can be a variable frequency motor. Furthermore, a protective shell can be provided outside the variable frequency motor to prevent the material from entering the variable frequency motor and affecting the normal operation of the variable frequency motor.
[0035] Optionally, in other embodiments, the rotating drive member 43 can also be fixed on the inner wall of the mixing pipeline 03 below the second discharge tray 42, and the output shaft of the rotating drive member 43 passes through the second discharge tray 42 and is transmission-connected to the first discharge tray 41, driving the first discharge tray 41 to rotate around the above-mentioned rotation axis, and the rotating drive member 43 has no overlapping part with the second discharge hole 421, and will not block the second discharge hole 421, thereby avoiding interference with the falling of materials from the second discharge hole 421.
[0036] Optionally, in other embodiments, the first discharge tray 41 or the second discharge tray 42 can be manually rotated around the above-mentioned rotation axis to adjust the relative position of the first discharge tray 41 and the second discharge tray 42 to adjust the overlap between the first discharge hole 411 and the second discharge hole 421, thereby adjusting the discharge speed of the material passing through the first discharge hole 411 and the second discharge hole 421.
[0037] Optionally, in other embodiments, the second material tray 42 can be set to be smaller than the first material tray 41, and the second material tray 42 can slide relative to the inner wall of the mixing pipeline 03 or the first material tray 41, so as to adjust the relative position of the first material tray 41 and the second material tray 42, so as to adjust the overlap between the first material hole 411 and the second material hole 421, so as to adjust the material discharge speed through the first material hole 411 and the second material hole 421. Optionally, the second material tray 42 is fixed relative to the first material tray 41 or the inner wall of the mixing pipeline 03 by sliding, snap or bolt.
[0038] Preferably, the first discharge hole 411 and the second discharge hole 421 are both circular holes, and the aperture of the first discharge hole 411 is greater than or equal to the aperture of the second discharge hole 421. When the automatic mixing device is working, the rotary drive member 43 drives the first discharge plate 41 to rotate. When the first discharge hole 411 and the second discharge hole 421 have overlapping parts, the material can enter the mixing pipeline 03 through the overlapping parts. When the first discharge hole 411 and the second discharge hole 421 do not overlap at all, the material cannot enter the mixing pipeline 03 through the adjustment component 04. By adjusting the rotation rate of the rotary drive member 43 or changing the apertures of the first discharge hole 411 and the second discharge hole 421, the discharge speed of the material in the first discharge component 01 entering the mixing pipeline 03 through the adjustment component 04 can be conveniently controlled, thereby adjusting the ratio of the two materials.
[0039] Preferably, in this embodiment, the aperture of the first material discharge hole 411 is larger than the aperture of the second material discharge hole 421, so that the granular material can smoothly pass through the first material discharge hole 411 and the second material discharge hole 421 into the mixing pipeline 03. Further, the diameter of the first material discharge hole 411 is 10-30 mm, and the diameter of the second material discharge hole 421 is 0.1-3 mm larger than the diameter of the first material discharge hole 411. Optionally, in other embodiments, the aperture of the first material discharge hole 411 may also be equal to the aperture of the second material discharge hole 421.
[0040] Further, in the present embodiment, the rotation axis is a line connecting the center of the first material discharge tray 41 and the center of the second material discharge tray 42, a plurality of first material discharge holes 411 are arranged at intervals along the circumference of the first material discharge tray 41, a plurality of second material discharge holes 421 are arranged at intervals along the circumference of the second material discharge tray 42, and the distance from each first material discharge hole 411 to the center of the first material discharge tray 41 is the same as the distance from each second material discharge hole 421 to the center of the second material discharge tray 42. When the automatic mixing device is working, when the center of the first material discharge hole 411 coincides with the center of the second material discharge hole 421, the material discharge amount reaches the maximum value, so that the material discharge speed of the first material discharge component 01 entering the mixing pipeline 03 through the adjustment component 04 can be controlled more accurately, so that the ratio of the two materials can be accurately adjusted.
[0041] Optionally, in other embodiments, a plurality of first feed holes 411 form a plurality of coaxially arranged first annular structures around the center of the first feed tray 41, and a plurality of second feed holes 421 form a plurality of coaxially arranged second annular structures around the center of the second feed tray 42, and the distance from each first annular structure to the center of the first feed tray 41 is the same as the distance from each second annular structure to the center of the second feed tray 42, and the number of first annular structures and second annular structures can be adaptively adjusted according to the demand for feed speed.
[0042] Preferably, in this embodiment, the first material discharge hole 411 and the second material discharge hole 421 are both arranged around the rotary drive member 43, and because the rotary drive member 43 is fixed to the lower surface of the second material discharge tray 42, the rotary drive member 43 is further prevented from blocking the material entering the mixing pipeline 03 through the first material discharge hole 411 and the second material discharge hole 421. Optionally, in other embodiments, the rotary drive member 43 can also be arranged at the intervals between the plurality of second material discharge holes 421, and in this case, the rotary drive member 43 is arranged on the inner wall of the mixing pipeline 03 below the second material discharge tray 42, further preventing the rotary drive member 43 from blocking the material entering the mixing pipeline 03 through the first material discharge hole 411 and the second material discharge hole 421.
[0043] Preferably, in this embodiment, the number of the first material discharge holes 411 is less than the number of the second material discharge holes 421. When the material in the first material discharge component 01 passes through the adjustment component 04, since the number of the first material discharge holes 411 is smaller, it is easier to control the amount of material passing through the first material discharge tray 41, thereby making it easier to adjust the discharge speed of the adjustment component 04. Optionally, in other embodiments, the number of the first material discharge holes 411 can also be set to be greater than the number of the second material discharge holes 421.
[0044] Specifically, in this embodiment, the first material tray 41 is provided with two first material holes 411, and the second material tray 42 is provided with eight second material holes 421. In other embodiments, the number of the first material holes 411 and the second material holes 421 can be adaptively adjusted according to the demand for material discharge speed.
[0045] Preferably, the first material discharge assembly 01 includes a first hopper 11 and a material shortage alarm device 12. The lower end of the first hopper 11 is connected to the mixing pipeline 03. The material shortage alarm device 12 is arranged in the first hopper 11. The material shortage alarm device 12 is configured to sound an alarm when the first hopper 11 is short of material, so that the staff can add materials or stop mixing in time. Specifically, the material shortage alarm device 12 includes a material shortage detection member and an alarm member that are communicatively connected. The material shortage detection member is arranged in the first hopper 11. In this embodiment, the material shortage detection member is a damping sensor, which detects the material amount by detecting the pressure of the material on the damping sensor. When the material shortage is detected, the signal can be transmitted to the alarm member so that the alarm member can sound an alarm. The alarm member can emit a specified sound and / or a specified light to indicate the material shortage alarm. In other embodiments, the material shortage detection member includes a photoelectric sensor, a weighing sensor, a speed sensor or a pressure sensor. This embodiment does not specifically limit the form of the material shortage detection member.
[0046] Preferably, the first material discharging assembly 01 further includes a first plug plate 13, which is movably provided at the connection between the first hopper 11 and the mixing pipeline 03, and the first plug plate 13 can be extended to the outlet of the first hopper 11 to block the first hopper 11 and the mixing pipeline 03, and the first plug plate 13 can also be retracted to a position avoiding the outlet of the first hopper 11 to connect the first hopper 11 and the mixing pipeline 03 to adjust whether the material in the first material discharging assembly 01 falls, and the first plug plate 13 can also be adjustable between the blocking position and the avoiding position to adjust the material discharging amount of the first hopper 11. Since the specific structure of the first plug plate 13 belongs to the prior art, it will not be described in detail in this embodiment.
[0047] Furthermore, if Figure 1As shown, the mixing pipeline 03 includes a first connecting branch pipe 31, a second connecting branch pipe 32 and a mixing main pipe 33. The mixing main pipe 33 is located below the first connecting branch pipe 31 and the second connecting branch pipe 32. The first connecting branch pipe 31 is arranged in the vertical direction. The regulating component 04 is arranged in the first connecting branch pipe 31. The upper end of the first connecting branch pipe 31 is connected to the first hopper 11, and the lower end of the first connecting branch pipe 31 is connected to the mixing main pipe 33. The upper end of the second connecting branch pipe 32 is connected to the second feeding component 02, and the lower end of the second connecting branch pipe 32 is connected to the mixing main pipe 33. The second connecting branch pipe 32 is connected from bottom to top away from the first connecting branch pipe. The direction of the branch pipe 31 is inclined. After the material in the first feeding component 01 enters the first connecting branch pipe 31, it enters the mixing main pipe 33 through the adjusting component 04. The material in the second feeding component 02 also enters the mixing main pipe 33 after passing through the second connecting branch pipe 32. The two materials meet in the mixing main pipe 33 to achieve mixing. Moreover, since the second connecting branch pipe 32 is inclined, the material in the second feeding component 02 has an impact force when entering the mixing main pipe 33 after passing through the second connecting branch pipe 32, so that the material in the first feeding component 01 is more evenly distributed when entering the material flow in the second feeding component 02, so that the two materials can be evenly mixed.
[0048] Preferably, the mixing main pipe 33 is hook-shaped, and the mixing main pipe 33 is bent upward from the end connected to the first connecting branch pipe 31 to the end. Since the end of the mixing main pipe 33 is bent upward, it plays a buffering role for the mixed materials, making it convenient for the suction pipe of the next processing link of the plastic product production line to suck away the mixed materials. When the suction pipe stops working, the small amount of materials remaining in the mixing main pipe 33 will not overflow. Specifically, in this embodiment, the central angle of the arc of the bent part of the mixing main pipe 33 is 45-60 degrees. In other embodiments, the central angle of the arc of the bent part of the mixing main pipe 33 can be adaptively adjusted according to specific circumstances.
[0049] It should be noted that, due to the limitation of the particle size of the material, if the size of the mixing main pipe 33 is too large, the instability of the mixing uniformity will increase. To this end, the first connecting branch pipe 31 includes a mounting pipe 311 and a reducing pipe 312, the upper end of the mounting pipe 311 is connected to the first hopper 11, the lower end of the mounting pipe 311 is connected to the upper end of the reducing pipe 312, the lower end of the reducing pipe 312 is connected to the mixing main pipe 33, the adjustment component 04 is installed in the mounting pipe 311, and the diameter of the reducing pipe 312 gradually decreases from the end connected to the mounting pipe 311 to the end connected to the mixing main pipe 33. The above-mentioned arrangement enables the diameters of the first discharge tray 41 and the second discharge tray 42 to be larger than the diameter of the mixing main pipe 33, leaving space for the installation of the rotating drive component 43, preventing the rotating drive component 43 from blocking the first discharge hole 411 or the second discharge hole 421, and the adjustment range of the diameter and number of the first discharge hole 411 and the second discharge hole 421 is also larger, thereby making the adjustable discharge speed range of the adjustment component 04 larger. In addition, when the diameter of the mixing main pipe 33 is too large, the uneven distribution of the material in the first feeding component 01 in the material in the second feeding component 02 during the mixing process will increase, and the bent part of the mixing main pipe 33 is prone to accumulation of materials, resulting in the suction pipe in the next processing link being difficult to suck away all the mixed materials, and is not conducive to the uniform mixing of the two materials. Therefore, the diameter of the mixing main pipe 33 is smaller than the diameter of the mounting pipe 311. Therefore, the diameter of the reducer 312 is gradually reduced from the end connected to the mounting pipe 311 to the end connected to the mixing main pipe 33, so that the first connecting branch pipe 31 can match the size of the mixing main pipe 33, so that the lower end of the first connecting branch pipe 31 is connected to the mixing main pipe 33.
[0050] In this embodiment, the diameter of the installation pipe 311 is 120-250 mm, and the diameters of the second connecting branch pipe 32 and the mixing main pipe 33 are both 60-90 mm. In other embodiments, the diameters of the components of the mixing pipeline 03 can be adaptively adjusted according to specific circumstances.
[0051] Preferably, an inspection port is provided on the mounting tube 311, and the mixing pipeline 03 is also provided with an inspection door 3111, the inspection door 3111 is movably connected to the mixing pipeline 03, and the inspection door 3111 is used to block or open the inspection port. When the adjustment component 04 fails, the staff can open the inspection door 3111 and inspect or replace the first discharge tray 41, the second discharge tray 42 and / or the rotating drive member 43 through the inspection port.
[0052] Preferably, an observation window 3112 is also provided on the mounting tube 311, and the observation window 3112 is opposite to the adjustment component 04, and is used to observe whether the adjustment component 04 is working normally. When it is observed that the first discharge tray 41 or the second discharge tray 42 is blocked, and the rotating drive component 43 fails, maintenance can be carried out through the inspection port.
[0053] Furthermore, the second unloading component 02 includes a second hopper 21, and the bottom of the second hopper 21 is set as a slope, which is inclined from bottom to top in a direction away from the mixing pipeline 03. A unloading port 22 is set at the bottom of the slope, and the unloading port 22 is connected to the second connecting branch pipe 32. The material in the second hopper 21 continuously enters the mixing pipeline 03 through the unloading port 22 under the action of gravity. Preferably, the angle between the slope and the horizontal direction is 30-45 degrees, so that the material in the second hopper 21 can be continuously discharged under the action of gravity.
[0054] Preferably, the second material discharging assembly 02 further includes a second plug plate 23, which is movably provided at the connection between the second hopper 21 and the second connecting branch pipe 32, and the second plug plate 23 can be extended to the outlet of the second hopper 21 to block the second hopper 21 and the second connecting branch pipe 32, and the second plug plate 23 can also be retracted to a position avoiding the outlet of the second hopper 21 to connect the second hopper 21 and the second connecting branch pipe 32 to adjust whether the material in the second material discharging assembly 02 falls, and the second plug plate 23 can also be adjustable between the blocking position and the avoiding position to adjust the material discharging amount of the second hopper 21. Since the specific structure of the second plug plate 23 belongs to the prior art, it will not be described in detail in this embodiment.
