[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The utility model provides an auxiliary loading and unloading device for the inner cylinder of a three-dimensional mixer, which is arranged on the side of the mixer and has a structure as follows: Figure 1As shown, it includes a bearing mechanism 100, an adjusting mechanism 200, an ejecting mechanism 300 and a driving mechanism 400.

[0025] When in use, the inner cylinder filled with materials is placed in the receiving cylinder 120, and the driving mechanism 400 is manipulated so that the driving mechanism 400 can drive the supporting frame 110 to move upward to a preset position, and then the adjusting mechanism 200 is manipulated so that the adjusting mechanism 200 can drive the receiving cylinder 120 to rotate around its rotation axis, so that the direction of the opening of the receiving cylinder 120 can be adjusted, so that the opening of the receiving cylinder 120 can be docked with the opening of the outer barrel of the mixer, and then the pushing mechanism 300 is manipulated so that the pushing mechanism 300 can abut against the inner cylinder in the receiving cylinder 120, so that the inner cylinder can be pushed into the outer barrel of the mixer. When the volume of the mixer is large, it is no longer necessary to manually load the inner cylinder into the outer barrel, nor is it necessary to manually take the inner cylinder out of the outer barrel, which makes it more convenient to load or take out the inner cylinder, reduces the labor intensity of the workers, and avoids physical injuries to the workers caused by the overweight inner cylinder.

[0026] As a preferred embodiment, please refer to Figure 1 The auxiliary loading and unloading device for the inner cylinder of the three-dimensional mixer also includes a frame 500, and the supporting frame 110 is slidably arranged on the frame 500, and the supporting frame 110 can be supported by the frame 500.

[0027] As a preferred embodiment, please refer to Figure 1 The adjustment mechanism 200 includes a first telescopic driving member 210, which is hinged on the supporting frame 110. The telescopic end of the first telescopic driving member 210 is hinged to one end of the receiving tube 120. By manipulating the first telescopic driving member 210, the telescopic end of the first telescopic driving member 210 can be extended or retracted, thereby driving the receiving tube 120 to rotate around its rotation axis, and adjusting the opening direction of the receiving tube 120 so that the opening of the receiving tube 120 can be docked with the opening of the outer barrel of the mixer.

[0028] As a preferred embodiment, please refer to Figure 1 The ejection mechanism 300 includes a second telescopic driving member 310, which is fixed to the other end of the receiving tube 120. The telescopic end of the second telescopic driving member 310 slides through the receiving tube 120 and extends into the receiving tube 120. By manipulating the second telescopic driving member 310, the telescopic end of the second telescopic driving member 310 can be extended and enter the receiving tube 120, abutting against the inner tube in the receiving tube 120, and pushing the inner tube to move along the axial direction of the receiving tube 120 until the inner tube completely enters the outer barrel of the mixer.

[0029] As a preferred embodiment, please refer to Figure 1 The driving mechanism 400 includes a screw rod 410 and a first rotating driving member 420. The screw rod 410 is vertically arranged. Both ends of the screw rod 410 are rotatably mounted on the frame 500. A screw hole is opened on the support frame 110, and the screw rod 410 is sleeved on the screw rod 410 through the screw hole. The screw hole is screwed with the screw rod 410. The first rotating driving member 420 is fixed on the frame 500. The output end of the first rotating driving member 420 is fixedly connected to one end of the screw rod 410 for driving the screw rod 410 to rotate. By controlling the first rotating driving member 420 to rotate forward or reverse, the first rotating driving member 420 can drive the screw rod 410 to rotate forward or reverse. Since the screw rod 410 is connected to the support frame 110 via the screw hole, when the screw rod 410 rotates forward or reverse, it can drive the support frame 110 to move upward or downward.

[0030] As a preferred embodiment, please refer to Figure 1 and Figure 2The auxiliary loading and unloading device for the inner cylinder of the three-dimensional mixer also includes a positioning mechanism 600, which includes a plurality of positioning shafts 610, a plurality of connecting members 620 and a positioning drive assembly 630. Each of the positioning shafts 610 is circumferentially arranged in the receiving cylinder 120 along the length direction of the receiving cylinder 120 to enclose a positioning channel for accommodating the inner cylinder. Each of the connecting members 620 corresponds to each of the positioning shafts 610 one by one. One end of the connecting member 620 is fixedly connected to the positioning shaft 610, and the other end of the connecting member 620 slides through the receiving cylinder 120 and extends to the outside of the receiving cylinder 120. The positioning drive assembly 630 is connected to the other end of each of the connecting members 620, and is used to drive each of the connecting members 620 along the length direction of the receiving cylinder 120. The receiving tube 120 is radially moved to adjust the diameter of the positioning channel. When the opening of the receiving tube 120 is docked with the opening of the outer barrel of the mixer, in order to allow the inner barrel to pass through the docking point between the receiving tube 120 and the outer barrel of the mixer without hindrance, it is necessary to ensure that the inner diameter of the receiving tube 120 is the same as the inner diameter of the outer barrel of the mixer. However, this means that only inner barrels of specific sizes can be placed in the receiving tube 120. When loading and unloading inner barrels of other sizes, the size of the receiving tube 120 needs to be replaced, resulting in poor applicability of the receiving tube 120. By arranging a plurality of the positioning shafts 610 in the receiving tube 120 and adjusting the diameter of the positioning channel, the positioning channel can be used to place inner barrels within a certain diameter range, thereby improving applicability.

[0031] As a preferred embodiment, please refer to Figure 2The positioning drive assembly 630 includes a transmission ring 631, a plurality of connecting shafts 632, a rotating shaft 633, a transmission member 634 and a second rotating drive member 635. The transmission ring 631 is rotatably sleeved on the receiving tube 120. The transmission ring 631 is circumferentially provided with a plurality of guide grooves 6311. The distances from the two ends of the guide groove 6311 to the center of the transmission ring 631 are unequal. Each of the connecting shafts 632 is circumferentially arranged on the outer side of the receiving tube 120 along the length direction of the receiving tube 120. Each of the connecting shafts 632 One end of each of the connecting shafts 632 is respectively fixedly connected to the other end of the corresponding connecting member 620, and the other end of each of the connecting shafts 632 slides through the corresponding guide groove 6311. The rotating shaft 633 is arranged on the outer side of the receiving tube 120 along the length direction of the receiving tube 120 and is rotatably installed on the receiving tube 120. The transmission member 634 is correspondingly connected to the rotating shaft 633, and the transmission member 634 is also correspondingly connected to the other end of one of the connecting members 620 to convert the rotation of the rotating shaft 633 into the corresponding connecting member 6 20 moves along the radial direction of the receiving tube 120, the second rotating driving member 635 is fixedly arranged at the other end of the receiving tube 120, the output end of the second rotating driving member 635 is fixedly connected to one end of the rotating shaft 633, and is used to drive the rotating shaft 633 to rotate, and the second rotating driving member 635 can drive the rotating shaft 633 to rotate forward or reverse by controlling the second rotating driving member 635 to rotate forward or reverse, because the transmission member 634 can convert the forward or reverse rotation of the rotating shaft 633 into the connecting member 620 moving along the The radial movement of the receiving tube 120, when the connecting member 620 moves inward or outward, will drive the corresponding connecting shaft 632 to slide in the guide groove 6311, so that the transmission ring 631 rotates. The rotation of the transmission ring 631 will drive the other connecting shafts 632 to slide in the corresponding guide groove 6311, so that the other connecting members 620 all move radially along the receiving tube 120, realizing the mutual retraction or separation of the connecting members 620, so that the diameter of the positioning channel can be adjusted.

[0032] As a preferred embodiment, please refer to Figure 2A plurality of rows of through grooves 121 are circumferentially formed on the side wall of the receiving tube 120, and the connecting member 620 includes at least two connecting rods 621, each of which slides through the corresponding through groove 121, and each of the connecting rods 621 is fixedly connected to form a whole via the corresponding connecting shaft 632. Since the positioning shaft 610 is relatively long, it is connected to the positioning shaft 610 through a plurality of connecting rods 621, and the positioning shaft 610 is guided to move radially along the receiving tube 120, thereby improving the stability of the movement of the positioning shaft 610.

[0033] As a preferred embodiment, please refer to Figure 2 The transmission member 634 includes at least two gears 6341 and at least two racks 6342. Each of the gears 6341 is coaxially fixed on the rotating shaft 633. Each of the racks 6342 is respectively fixed on the other end of the corresponding connecting rod 621 and meshes with each of the gears 6341 one by one. According to the meshing transmission principle of the gears 6341 and the racks 6342, when the gears 6341 rotate, the racks 6342 can move.

[0034] As a preferred embodiment, please refer to Figure 1 The frame 500 includes a bottom plate 510, a plurality of guide rods 520, a top plate 530 and a plurality of rollers 540. Each of the guide rods 520 is vertically arranged, and the bottom of each of the guide rods 520 is fixed on the bottom plate 510. The top plate 530 is fixed on the top of each of the guide rods 520. The support frame 110 is slidably sleeved on each of the guide rods 520. Each of the rollers 540 is fixed on the lower surface of the bottom plate 510. The support frame 110 can be guided by each of the guide rods 520, so that when the screw rod 410 rotates, the support frame 110 does not rotate but moves up and down.

[0035] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of the utility model is described in detail:

[0036] When in use, the diameter of the positioning channel is adjusted according to the outer diameter of the inner cylinder, and the second rotating driving member 635 is controlled to rotate forward or reversely, so that the second rotating driving member 635 can drive the rotating shaft 633 to rotate forward or reversely. Since the transmission member 634 can convert the forward or reverse rotation of the rotating shaft 633 into the radial movement of the connecting member 620 along the carrying cylinder 120, when the connecting member 620 moves inward or outward, it will drive the corresponding connecting shaft 632 to slide in the guide groove 6311, so that the transmission ring 631 rotates. The rotation of the transmission ring 631 will drive the other connecting shafts 632 to slide in the corresponding guide grooves 6311, so that the other connecting members 620 can move along the radial direction of the receiving cylinder 120, so as to realize the mutual retraction or separation of the connecting members 620, so that the diameter of the positioning channel can be adjusted to make the diameter of the positioning channel the same as the inner diameter of the outer barrel of the mixer. When the opening of the receiving cylinder 120 is docked with the opening of the outer barrel of the mixer, the inner cylinder can pass through the docking point of the receiving cylinder 120 and the outer barrel of the mixer without hindrance, and then the inner cylinder filled with materials can be placed. The first rotating driving member 420 is controlled to rotate forwardly in the receiving tube 120, so that the first rotating driving member 420 can drive the screw rod 410 to rotate forwardly. Since the screw rod 410 is connected to the support frame 110 via the screw hole, when the screw rod 410 rotates forwardly, it can drive the support frame 110 to move upward to a preset position, and then the first telescopic driving member 210 is controlled so that the first telescopic driving member 210 can drive the receiving tube 120 to rotate around its rotation axis, and the opening direction of the receiving tube 120 is adjusted so that the opening of the receiving tube 120 is It can be docked with the opening of the outer barrel of the mixer, and then by manipulating the second telescopic driving member 310, the telescopic end of the second telescopic driving member 310 can enter the receiving tube 120, abut against the inner tube in the receiving tube 120, and push the inner tube to move along the axial direction of the receiving tube 120 until the inner tube completely enters the outer barrel of the mixer. When the volume of the mixer is large, it is no longer necessary to manually load the inner tube into the outer barrel or manually take the inner tube out of the outer barrel, which makes it more convenient to load or take out the inner tube, reduces the labor intensity of workers, and avoids physical injuries to workers caused by overweight inner tubes.

[0037] The utility model provides an auxiliary loading and unloading device for the inner cylinder of a three-dimensional mixer, which has the following beneficial effects:

[0038] (1) After the opening of the receiving tube 120 is docked with the opening of the outer barrel of the mixer, in order to allow the inner barrel to pass through the docking point of the receiving tube 120 and the outer barrel of the mixer without hindrance, it is necessary to ensure that the inner diameter of the receiving tube 120 is the same as the inner diameter of the outer barrel of the mixer. However, this means that only inner barrels of a specific size can be placed in the receiving tube 120. When loading and unloading inner barrels of other sizes, the size of the receiving tube 120 needs to be changed, resulting in poor applicability of the receiving tube 120. By arranging a plurality of the positioning shafts 610 in the receiving tube 120 and adjusting the diameter of the positioning channel, the positioning channel can accommodate inner barrels within a certain diameter range, thereby improving applicability.

[0039] (2) By manipulating the second rotating driving member 635 to rotate forward or reverse, the second rotating driving member 635 can drive the rotating shaft 633 to rotate forward or reverse. Since the transmission member 634 can convert the forward or reverse rotation of the rotating shaft 633 into the radial movement of the connecting member 620 along the receiving tube 120, when the connecting member 620 moves inward or outward, it will drive the corresponding connecting shaft 632 to slide in the guide groove 6311, so that the transmission ring 631 rotates. The rotation of the transmission ring 631 will drive the other connecting shafts 632 to slide in the corresponding guide grooves 6311, so that the other connecting members 620 move along the radial direction of the receiving tube 120, so that the connecting members 620 can be retracted or separated from each other, so that the diameter of the positioning channel can be adjusted;

[0040] (3) When the mixer is large in size, it is no longer necessary to manually load the inner cylinder into the outer cylinder or to manually remove the inner cylinder from the outer cylinder, which makes loading or removing the inner cylinder more convenient and reduces the labor intensity of workers, thus avoiding physical injuries to workers caused by overweight inner cylinders.

[0041] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
