Description

Technical Field

[0001] The present invention relates to the technical field of agitators, and in particular to an agitator driving system and an agitator system with a locking component. Background Art

[0002] Stirring equipment is one of the important and indispensable equipment in the biopharmaceutical industry. Stirring equipment is divided into mechanical stirring and magnetic stirring. Mechanical stirring has poor sealing performance, so magnetic stirring devices have become the mainstream of stirring equipment today. Magnetic stirring devices usually include a tank body, stirring blades and a magnetic drive. Both the stirring blades and the magnetic drive are equipped with driving magnets. The magnetic drive drives the stirring blades to rotate in the tank body through the magnetic connection of two driving magnets. Products generally need to be mixed regularly in multiple tanks. If each tank is equipped with a magnetic drive, it will not only cause a waste of resources, but also greatly increase production costs. Summary of the invention

[0003] A first object of the present invention is to provide an agitator drive system having a locking assembly.

[0004] A second object of the present invention is to provide an agitator system having a locking assembly.

[0005] In order to achieve the above-mentioned first purpose, the present invention provides an agitator drive system with a locking assembly, including a magnetic drive and a mobile trolley, the mobile trolley including a frame, an operating part, a fixed rod and a locking assembly, the frame is provided with a front end and a rear end in the insertion direction, and the magnetic drive is arranged on the frame; the operating part is arranged at the rear end of the frame; the fixed rod is arranged at the front end of the frame, and the extension direction of the fixed rod is perpendicular to the insertion direction; the locking assembly includes a first locking frame, two first connecting shafts and two first hinges, the first locking frame is connected between the two first connecting shafts, the first hinge is arranged at the rear end of the frame, the two first hinges are located on both sides of the frame, the first hinge is provided with a first hinge hole, the first connecting shaft is connected to the first hinge hole, and the first locking frame can rotate around the first connecting shaft.

[0006] It can be seen from the above scheme that by setting the first locking frame to rotate around the first connecting axis, when the magnetic drive is connected to the stirring head, the first locking frame is rotated to a vertical state, so that the first locking frame is connected to the connecting frame arranged at the bottom of the tank body, and under the joint action of the fixing rod and the first locking frame, the moving trolley is firmly connected to the connecting frame, thereby improving the connection stability between the magnetic drive and the stirring head.

[0007] A further solution is that the locking assembly also includes a second locking frame, two second connecting shafts and two second hinges, the second locking frame is located on one side of the first locking frame, the second locking frame is connected between the two second connecting shafts, the second hinge is arranged at the rear end of the frame, the two second hinges are arranged on both sides of the frame, the second hinge and the first hinge are staggered in the insertion direction, the second hinge is provided with a second hinge hole, the second connecting shaft is connected to the second hinge hole, and the second locking frame can rotate around the second connecting shaft.

[0008] It can be seen from the above solution that by arranging the second locking frame on one side of the first locking frame, when necessary, a suitable locking frame can be selected to be connected to the connecting frame, thereby improving the adaptability of the locking assembly.

[0009] A further solution is that the locking assembly also includes a third locking frame, two third connecting shafts and two third hinges. The third locking frame is located on a side of the second locking frame away from the first locking frame. The third locking frame is connected between the two third connecting shafts. The first hinge, the second hinge and the third hinge are arranged in sequence along the insertion direction. The third hinge and the first hinge are arranged in alignment along the insertion direction. A third hinge hole is provided on the third hinge. The third connecting shaft is connected to the third hinge hole. The third locking frame can rotate around the third connecting shaft.

[0010] It can be seen from the above solution that by arranging the third locking frame on the side of the second locking frame away from the first locking frame, a suitable locking frame can be selected to be connected to the connecting frame when necessary, thereby further improving the adaptability of the locking assembly.

[0011] A further solution is that the first locking frame, the second locking frame and the third locking frame are all arranged in parallel, and the second locking frame is staggered with the first locking frame and the third locking frame in the insertion direction.

[0012] It can be seen from the above scheme that by arranging the second locking frame to be staggered with the first locking frame and the third locking frame in the insertion direction, collision or interference between the locking frames during rotation can be prevented, which not only avoids affecting the appearance of the locking frames, but also ensures the normal use of each locking frame.

[0015] A further solution is that, in the insertion direction, the distance from the first hinge to the third hinge is greater than the sum of the lengths of the second swing arm and the sixth swing arm.

[0016] It can be seen from the above scheme that by setting the distance between the first hinge and the third hinge to be greater than the sum of the lengths of the second swing rod and the sixth swing rod, when the first locking frame and the third locking frame swing relative to each other, the two will not collide or stack up and down due to interference.

[0017] A further solution is that the first swing rod, the third swing rod and the fifth swing rod can all be at the same height as the fixed rod in the vertical direction.

[0018] It can be seen from the above scheme that by setting the first swing arm, the third swing arm and the fifth swing arm to have the same height in the vertical direction as the fixed rod, when the locking operation is performed using the first locking frame, the second locking frame or the third locking frame, the front and rear ends of the frame are in a horizontal state, which is conducive to keeping the magnetic drive in a vertical state.

The locking device is arranged between the operating part 7 and the magnetic drive 1. The locking device is hinged on both sides of the frame 2. The locking device includes a locking rod. The locking rod extends along the X direction. The locking rod can rotate in the vertical direction. When the locking rod rotates to the highest point, it is at the same height as the fixed rod 3. At this time, the locking rod can be connected to the connecting frame 101 to realize the locking operation of the mobile trolley in the vertical direction.

[0032] The frame 2 is provided with a fixing plate 4 and a rotary drive motor, the fixing plate 4 is located on one side of the fixing rod 3, the magnetic drive 1 is arranged on the top wall of the fixing plate 4 along the Z direction, the rotary drive motor is arranged on the bottom wall of the fixing plate 4, and the rotary drive motor passes through the fixing plate 4 and is connected to the magnetic drive 1 to drive the magnetic drive 1 to rotate. The driving head of the magnetic drive 1 is arranged upward, and the driving head of the magnetic drive 1 is higher than the fixing rod 3 in the Z direction, so as to be conveniently connected to the stirring head.

[0033] In the Y direction, the distance from the magnetic driver 1 to the fixed rod 3 is smaller than the distance from the magnetic driver 1 to the operating part 7. When the frame 2 drives the magnetic driver 1 to rotate around the fixed rod 3 until the magnetic driver 1 is connected to the connecting end of the stirring head, not only the rotation amplitude of the frame 2 can be reduced, but also the driving force applied to the operating part 7 can be reduced, thereby achieving a labor-saving effect.

[0034] The mobile device includes a first roller support foot 5 and a second roller support foot 6. The first roller support foot 5 is located at the lower side of the middle part of the frame 2, and the second roller support foot 6 is arranged on the first roller support foot 5.

Specifically, the first hinge 26 and the third hinge 28 are arranged on the first side of the longitudinal beam 23 along the Y direction, and the second hinge 27 is arranged on the second side of the longitudinal beam 23. The first hinge 26 is provided with a first hinge hole, the second hinge 27 is provided with a second hinge hole, and the third hinge 28 is provided with a third hinge hole. The first hinge hole, the second hinge hole and the third hinge hole are higher than the top wall of the longitudinal beam 23 in the Z direction.

[0046] The first connecting shaft is connected to the first hinge hole, so that the first locking frame 81 can rotate around the first connecting shaft, the second connecting shaft is connected to the second hinge hole, so that the second locking frame 82 can rotate around the second connecting shaft, and the third connecting shaft is connected to the third hinge hole, so that the third locking frame 83 can rotate around the third connecting shaft.

[0047] In the Y direction, the distance between the first hinge 26 and the third hinge 28 is greater than the sum of the lengths of the second swing rod 812 and the sixth swing rod 832, so that when the second swing rod 812 and the sixth swing rod 832 rotate relative to each other to the horizontal direction, no collision occurs due to interference, which facilitates the storage of the first locking frame 81 and the third locking frame 83. Since the second hinge 27 is staggered with the first hinge 26 and the third hinge 28 in the Y direction, the second locking frame 82 will not collide with the first locking frame 81 or the third locking frame 83 no matter which side it rotates to. The first swing rod 811, the third swing rod 821 and the fifth swing rod 831 are all locking rods of the locking device.

[0051] See also Figure 2 and Figure 3 The agitator drive system also includes a control box 11 and an operating module 111. The control box 11 is located in the middle of the frame 2 and on the first roller support foot 5, so that the center of gravity of the control box 11 is located below the frame 2, and the center of gravity of the agitator drive system falls on the first roller support foot 5. The operating module 111 is arranged at the rear end 22 of the frame 2 and on one side of the operating part 7, so that the staff can control the operating module 111 conveniently. The center of gravity of the operating module 111 is located below the frame 2. A controller is arranged in the control box 11, and the controller is electrically connected to the operating module 111 and the rotating motor respectively. The rotating motor drives the magnetic drive 1 to rotate. The operating module 111 is arranged between the two beams. The operating module 111 includes a speed control panel, which is electrically connected to the magnetic drive 1 and is used to control the rotation speed of the magnetic drive 1.

[0052] The total weight of the magnetic drive 1 and the rotary motor is greater than the weight of the operating module 111. In the Y direction, the distance from the magnetic drive 1 to the control box 11 is less than the distance from the operating module 111 to the control box 11. This is beneficial to achieve a balanced weight of the agitator drive system and reduce the resistance when the manual control frame 2 rotates around the center of the first roller group 53.

[0053] See also Figure 6 , the frame 2 rotates in the Z direction around the center of the first roller group 53, so that the front end 21 of the frame 2 is higher than the rear end 22 of the frame 2. At this time, the first roller group 53 is located on the ground, and the second roller group 63 is suspended above the first roller group 53, so that the fixing rod 3 can be connected to the second end of the connecting frame 101, so that the bearing 34 on the fixing rod 3 is embedded in the second limiting groove 103. At this time, the operating part 7 can be manually operated to make the bearing 34 roll on the connecting frame 101 along the Y direction, so that the moving trolley drives the magnetic driver 1 to move along the extension direction of the connecting frame 101 until the bearing 34 falls into the first limiting groove 102.

[0054] See also Figure 1 When the bearing 34 on the fixed rod 3 falls into the first limiting groove 102, the rear end 22 of the moving trolley can be lifted by the operating part 7, so that the moving trolley drives the magnetic driver 1 to rotate around the fixed rod 3 until the driving head of the magnetic driver 1 is connected to the connecting end of the stirring head. Then the position of the movable locking frame in the Y direction can be adjusted, and the movable locking frame can be rotated to connect the first swing arm 92 to the connecting frame 101, and the agitator drive system is locked to the tank body 100. At this time, the first roller support foot 5 and the second roller support foot 6 are both in a suspended state.

[0055] See also Figure 7When the agitator driving system moves between the two tanks 100, the first roller group 53 and the second roller group 63 are both located on the ground, and the first roller group 53 and the second roller group 63 rotate in the same direction. At this time, the line connecting the first roller group 53 and the second roller group 63 in the Y direction intersects with the plane where the frame 2 is located, and the plane where the frame 2 is located is parallel to the plane where the longitudinal beam 23 and the cross beam 24 are located. The rear end 22 of the frame 2 is higher than the front end 21 of the frame 2 in the Z direction, and the front end 21 of the frame 2 is higher than the second roller group 63 in the Z direction, so that the front end 21 of the frame 2 does not directly contact the ground, avoiding affecting the movement of the moving trolley. The distance from the first roller support foot 5 to the second roller group 63 is smaller than the distance from the first roller support foot 5 to the front end 21 of the frame 2, so that the second roller group 63 does not protrude from the front end 21 of the frame 2, affecting the connection between the fixing rod 3 on the front end 21 of the frame 2 and the connecting frame 101.

[0056] The above-mentioned embodiment is only a preferred embodiment of the present invention. In practical applications, a suitable locking rod can be selected for locking according to the specific position of the second limit groove of the connecting frame in the Y direction. This embodiment is compatible with a variety of connecting frames of different specifications, thereby improving the adaptability and practicality of the agitator drive system.
