Description

Technical Field

[0001] The utility model relates to the technical field of column packing machines, in particular to a centrifuge tube column packing machine. Background Art

[0002] A centrifuge tube is a tubular sample container that can be equipped with a sealing cap or a pressure cap. It is mainly used for the separation and preparation of various biological samples. The biological sample suspension is placed in the centrifuge tube. Under high-speed rotation, due to the huge centrifugal force, the suspended tiny particles, such as organelles and biological macromolecules, are sedimented at a certain speed, thereby being separated from the solution. When preparing the sample, the centrifuge tubes need to be inserted into the slots of the holder one by one to facilitate subsequent feeding and centrifugation operations.

[0003] The centrifuge tubes currently used are partially inserted into the slots manually, but manual insertion is time-consuming and labor-intensive, with high labor costs, and the centrifuge tubes are easily damaged if they fall during insertion. Some are inserted using a column loading machine, but since the top of the outer surface of the centrifuge tube has a threaded tube body for sealing, and the diameter of the threaded tube body is larger than the diameter of the centrifuge tube body, the surface of the centrifuge tube is not uniform. Therefore, the existing column loading machine still needs to separate the centrifuge tubes one by one and then load them through a conveying mechanism for insertion, which still requires manual cooperation, and the insertion structure is relatively cumbersome. In view of the above-mentioned defects, the present invention is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a centrifuge tube column packing machine to solve the problems raised.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a centrifuge tube column packing machine, comprising an X-axis movable frame and a storage barrel, wherein the output end of the X-axis movable frame is fixed with a Y-axis movable frame, and the output end of the Y-axis movable frame is fixed with a Z-axis movable frame for adjusting the position of the storage barrel, and the output end of the Z-axis movable frame is detachably fixed with the storage barrel, and a column packing assembly is provided at the bottom of the storage barrel;

[0006] The transmission gears are fixed to the two rear ends of the drive gears, and the two rear ends are meshed with each other, and the two gears are meshed with each other. A column motor is installed at the rear end of the support plate, and the output end of the column motor is fixed to the transmission gears on one side.

[0007] Preferably, the X-axis movable frame, the Y-axis movable frame and the Z-axis movable frame are all composed of a support frame, a servo motor, a screw rod, a movable sleeve block and a limit slide rod. A servo motor is installed at one end of each support frame, and a screw rod is rotatably connected to the inside of each support frame through a bearing, and a movable sleeve block is threadedly sleeved on the screw rod, and the top of the movable sleeve block is slidably sleeved with a limit slide rod, and the limit slide rod is fixed on the inner wall of the support frame, and one end of each screw rod is fixed to the output shaft of the servo motor.

[0008] Preferably, the X-axis moving frame, the Y-axis moving frame and the Z-axis moving frame are all arranged perpendicular to each other, and each of the moving sleeve blocks is provided with a threaded hole cooperating with the screw rod and a limiting sliding hole cooperating with the limiting sliding rod.

[0009] Preferably, the inner diameter of the storage barrel is equal to the outer diameter of the centrifuge tube, the width of each movable groove is greater than the width of the column packing assembly, and the height of the column packing assembly is less than the height of the movable groove.

[0010] Preferably, the distance between each two column packing assemblies is smaller than the distance between each two edges of the centrifuge tubes, and the distance between the column packing assemblies on both sides is larger than the width of the lower portion of the centrifuge tube and smaller than the width of the top threaded tube body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a column packing assembly that can discharge materials one by one. When packing the column, after the stacked centrifuge tubes are loaded into the storage barrel, the support block is driven by the turntable to rotate and the materials are discharged one by one, so that the centrifuge tubes can be inserted into the bracket one by one without having to operate one by one. This solves the problem that the existing column packing machine still needs to separate the centrifuge tubes one by one and then load and insert them through the conveying mechanism, which greatly reduces the convenience of centrifuge tube insertion.

[0014] 2. In the present invention, the positions of the storage barrel and the column packing assembly can be adjusted according to the specifications of the centrifuge tube holder through the three-axis movable platform during column packing, so that the bottom of the storage barrel can be aligned with the holder slot one by one, thereby facilitating the centrifuge tubes to be inserted into the holder one by one, and at the same time greatly improving the convenience and applicability of the column packing machine when used.

[0021] The following further illustrates the above and other technical features and advantages of the present invention in conjunction with the accompanying drawings and embodiments. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive. Example

[0022] like Figure 1-4As shown, the utility model provides a centrifuge tube column packing machine, comprising an X-axis movable frame 1 and a storage barrel 4, wherein the output end of the X-axis movable frame 1 is fixed with a Y-axis movable frame 2, and the output end of the Y-axis movable frame 2 is fixed with a Z-axis movable frame 3 for adjusting the position of the storage barrel 4, and the output end of the Z-axis movable frame 3 is detachably fixed with the storage barrel 4, and a column packing assembly 5 is provided at the bottom of the storage barrel 4;

[0023] The column assembly 5 includes a support plate 51, a rotating rod 52, a turntable 53 and a support block 54. The bottom surface of the Z-axis moving frame 3 on the rear side of the bottom of the storage barrel 4 is fixed with a support plate 51 by bolts. The rotating rods 52 are symmetrically inserted into the support plate 51, and the rotating rods 52 are rotatably connected to the support plate 51 through bearings. The two rotating rods 52 extend to one end below the storage barrel 4 and are fixed to the turntable 53, and a number of support blocks 54 are fixed on the outer surface of the turntable 53 at equal distances. The bottom of the storage barrel 4 is symmetrically provided with movable grooves 6 that cooperate with the support blocks 54. The support plates 51 on the inner sides of the two rotating rods 52 are rotatably connected to Transmission rod 55, each transmission rod 55 and rotating rod 52 are fixed with a pulley 56, and the two pulleys 56 on each side are connected by a transmission belt 57. Gears 59 are fixed to the outer surface of the rear sides of the two transmission rods 55, and the two gears 59 are meshed and connected. A column motor 58 is installed on the rear side of the support plate 51, and the output end of the column motor 58 is fixed to the transmission rod 55 on one side. The two gears 59 rotate in opposite directions. The diameters of the two gears 59 are the same. The tops of the support plates 51 on both sides of the Z-axis moving frame 3 are fixed with mounting plates, and the mounting plates and the storage barrel 4 are fixed to the Z-axis moving frame 3 by bolts.

[0024] When it is necessary to load the columns, the stacked centrifuge tubes are placed inside the storage barrel 4, and then the position of the storage barrel 4 is adjusted by the cooperation of the X-axis moving frame 1, the Y-axis moving frame 2 and the Z-axis moving frame 3. After the adjustment is completed, the column loading motor 58 is operated to drive the transmission rotating rod 55 to rotate. The transmission rotating rod 55 rotates to drive the fixed gear 59 to rotate, which can drive the other gear 59 meshed with the gear 59 to rotate relatively, which can drive the other transmission rotating rod 55 to rotate relatively at the same time, and can drive the rotating rod 52 to rotate relatively through the pulley 56 and the transmission belt 57, thereby driving the turntable 53 to rotate relatively. When the turntable 53 rotates, the supporting block 54 inside the movable groove 6 rotates downward, which can release its support for the centrifuge column, and the lowermost centrifuge column falls. At the same time, the other set of supporting blocks 54 rotates to the inside of the movable groove 6. At this time, the centrifuge tube slides down under the action of its own gravity to fill the position, which can make the movable groove 6 continue to support the lowermost centrifuge tube.

[0025] The X-axis moving frame 1, the Y-axis moving frame 2 and the Z-axis moving frame 3 are all composed of a support frame 11, a servo motor 12, a screw rod 13, a movable sleeve 14 and a limit slide 15. A servo motor 12 is installed at one end of each support frame 11. A screw rod 13 is rotatably connected to the interior of each support frame 11 through a bearing, and a movable sleeve 14 is threadedly sleeved on the screw rod 13. The top of the movable sleeve 14 is slidably sleeved with a limit slide 15, and the limit slide 15 is fixed on the inner wall of the support frame 11. One end of each screw rod 13 is fixed on the output shaft of the servo motor 12. The X-axis moving frame 1 The Y-axis moving frame 2 and the Z-axis moving frame 3 are all arranged perpendicular to each other, and each moving sleeve block 14 is provided with a threaded hole that cooperates with the screw rod 13 and a limiting slide hole that cooperates with the limiting slide rod 15. Through the cooperation of the support frame 11, the servo motor 12, the screw rod 13, the moving sleeve block 14 and the limiting slide rod 15, the material storage barrel 4 can be driven to move according to the slot on the column loading bracket, and the auxiliary cooperation with the material storage barrel 4 is convenient for the column loading operation. When moving, the servo motor 12 drives the screw rod 13 to rotate, which can drive the moving sleeve block 14 to move with the cooperation of the limiting slide rod 15.

[0026] The inner diameter of the storage barrel 4 is equal to the outer diameter of the centrifuge tube, the width of each movable groove 6 is greater than the width of the column packing assembly 5, and the height of the column packing assembly 5 is less than the height of the movable groove 6, ensuring that when the column packing assembly 5 rotates, the movable groove 6 will not affect its movement, the distance between the two column packing assemblies 5 is less than the distance between the edges of each two centrifuge tubes, and the distance between the column packing assemblies 5 on both sides is greater than the width of the lower part of the centrifuge tube and less than the width of the top threaded tube body, ensuring that the two column packing assemblies 5 on both sides can support the threaded tube body at the top of the centrifuge tube.

[0027] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
