Description

Technical Field

[0001] The invention relates to the technical field of filling, and in particular to a multi-cupway densification filling mechanism. Background Art

[0002] The working principle of the commonly used horizontal screw filling device is to transport the powder horizontally forward through a horizontal screw. After the powder is transported out of the outlet, it is transported to the packaging container through a pipe with a certain angle. This technology is generally suitable for powders with good fluidity; for powders with poor fluidity, the space between the spiral blades cannot be completely filled due to the slow flow rate, resulting in differences in capacity. At the same time, because the powder is too fine, the powder often sticks to the channel wall in the channel, causing material accumulation, inaccurate filling and other problems; in addition, the metering filling machines in the prior art mostly use single-row screw metering filling. Although the structure is simple and the machine cost is low, the filling efficiency is slow and the production efficiency is low, which is difficult to meet the needs of large-scale and large-scale production.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1 to 5 A multi-cup channel densification filling mechanism includes a mounting frame 1, a bracket 2 slidably connected to the mounting frame 1, a feeding device connected to the bracket 2 in a liftable manner, and a lifting mechanism 3 arranged directly below the feeding device. The feeding device includes a lifting device 4 and a storage bin 5 fixed to the lifting device 4. A feeding bin 6 is connected to the side of the storage bin 5. An open feeding hopper 61 is arranged at the top of the feeding bin 6. The bottom of the feeding bin 6 is connected to the storage bin 5 through a feeding screw. The storage bin 5 is distributed into six sub-bins 51. The top of the storage bin 5 is provided with filling mechanisms 7 respectively arranged corresponding to the sub-bins 51, and the top of the lifting mechanism 3 is provided with supporting cups respectively arranged corresponding to the sub-bins 51.

[0024] In this technical solution, the mounting frame is fixed to the frame by screws, etc. The opening of the feeding hopper is a 1.5-inch round opening and is connected to the outlet of the external vacuum loading bin through a suction hose. After the powder raw material is added, it is sent into the storage bin by the feeding screw. The filling mechanism in each sub-bin feeds the material separately and fills it into the package. The lifting mechanism improves the consistency of powder filling and facilitates subsequent packaging processing. The present invention has a compact structure and is equipped with an external weighing module. The filling error can be controlled within ±1%. Multiple cup channels are used for single simultaneous filling to improve the filling efficiency of the entire line and save equipment space.

[0025] Furthermore, the mounting frame 1 includes two fixed plates arranged in parallel, and two sides of the bracket 2 are slidably connected to the inner sides of the fixed plates through slide rails.

[0026] In this technical solution, support rods are respectively connected to the bottom of both ends of the two fixing plates to improve the fixing strength of the mounting frame. The mounting frame is also provided with conventional devices such as limit blocks and positioning locking mechanisms. The specific structure belongs to the prior art and will not be described in detail here.

[0027] Furthermore, the bracket 2 includes a base 21 slidably connected to the fixed plate and vertical plates 22 respectively arranged at two ends of the base, and the lifting device 4 is slidably connected to the vertical plates 22 .

[0028] In this technical solution, the cross-section of the base is an L-shaped structure, the two ends of the two brackets are respectively connected with reinforcing rods, and the two ends of the lifting device are respectively fixed between the corresponding vertical plates.

[0029] Furthermore, the lifting device 4 includes a driving device 41, a slide plate 42 and a connecting rod 43 connected between the driving device 41 and the slide plate 42. Both ends of the driving device 41 are respectively fixed between corresponding vertical plates, and the slide plate 42 is slidably connected to the corresponding vertical plates through a first guide rail 44.

[0030] In this technical solution, the driving device drives the slider to reciprocate through the connecting rod, and the guide rail ensures that the slider always moves in the vertical direction.

[0031] Furthermore, the driving device 41 includes a mounting seat 411 with two ends respectively fixed to the corresponding vertical plates, a first rotating shaft 412 rotatably disposed on the mounting seat, and a first motor 413 drivingly connected to the first rotating shaft 412 .

[0032] In this technical solution, the first motor is driven and connected to the first rotating shaft through conventional devices such as a gear box, and the specific structure will not be expanded one by one. The mounting seat 411 is assembled from multiple plates.

[0033] Furthermore, both ends of the first rotating shaft 412 are connected to the mounting seat 411 through bearing seats and protrude from the mounting seat 411. Both ends of the first rotating shaft 412 are connected to the driving block 414, and both ends of the connecting rod are connected to the driving block 414 and the slider through hinge pins. The first rotating shaft 412 is eccentrically arranged with the corresponding hinge pin.

[0034] In this technical solution, the driving block is equivalent to a cam structure. During the rotation of the first rotating shaft, the driving block and the connecting rod drive the slider to move back and forth, thereby realizing the lifting and lowering of the storage bin and completing the filling and making way after filling.

[0035] Furthermore, the storage bin 5 is connected to the lifting device 4 through the top plate 8, and the filling mechanism 7 includes a variable pitch screw 71 respectively arranged in the sub-bin 51 and a second motor 72 drivingly connected to the variable pitch screw 71, and the second motor 72 is connected to the variable pitch screw 71 through a transmission shaft 73.

[0036] In this technical solution, the structures of the second motor, the variable pitch screw and the transmission shaft itself belong to the prior art. The second motor is connected to the transmission shaft through a coupling and drives the variable pitch screw to rotate.

[0037] Furthermore, it also includes a stirring and stacking mechanism 9, which includes a rotating sleeve 91 sleeved on the transmission shaft 73, a stirring shaft 92 corresponding to the variable pitch screw 71 and a third motor 93 drivingly connected to the rotating sleeve, the third motor is driven and connected to the rotating sleeve through a gear pair 94, and a bearing is provided between the rotating sleeve and the transmission shaft 73.

[0038] In this technical solution, the rotating sleeve and the transmission shaft rotate independently without interfering with each other. The gear pair includes a gear sleeved on the rotating sleeve and an idler gear meshing with the adjacent gears, and is driven by a third motor. The gear pair can also be realized by a synchronous pulley set. Bearings are provided on the upper and lower surfaces of the gear. The third motor and the top plate are fixed by a sleeve. The gear is arranged in the sleeve. The outer wall of the sleeve is processed with a giveway groove for the meshing of the gear with the corresponding idler gear. After the variable pitch screw completes feeding, the third motor starts and the stirring shaft rotates to continuously replenish the variable pitch screw with materials, completely filling the space between the spiral blades and improving the filling accuracy.

[0039] Furthermore, the lifting mechanism 3 includes a connecting plate 31 fixed to the external frame, a second rotating shaft 32 whose two ends are rotatably connected to the connecting plate, a fourth motor 33 and a cup mounting bracket 34 driven and connected to the second rotating shaft, the two ends of the cup mounting bracket 34 are respectively connected to the connecting plate through second guide rails 35, and the bottom of the cup mounting bracket 34 is driven and connected to the second rotating shaft.

[0040] Furthermore, a connecting boss is protruding from the bottom of the cup mounting frame 34, a cam 36 is sleeved on the second rotating shaft, and the connecting boss is connected to the cam through a connecting pin.

[0041] In the above two technical solutions, the fourth motor drives the second rotating shaft to rotate. During the rotation, the cam drives the cup mounting frame to rise and fall, thereby realizing the lifting and lowering of the cup, which can make the powders closer and improve the consistency of filling.

[0042] In summary, the present invention has a compact structure, adds a stirring shaft, continuously replenishes materials for the variable pitch screw, completely fills the space between the spiral blades, improves the filling accuracy, adopts multiple cup channels for single simultaneous filling, improves the filling efficiency of the entire line, and saves equipment space.
