Description

Technical Field

[0001] The utility model relates to the technical field of automatic material receiving, in particular to a conical bottle supplementary material receiving device. Background Art

[0002] Liquid chromatography (HPLC) is widely used in biochemistry, drug analysis, environmental monitoring and other fields. It is an instrument used to separate, identify and quantify chemical substances. It uses liquid as the mobile phase and separates the substances to be tested through the principles of chemical affinity, size repulsion, ion exchange capacity and other principles on the surface of the stationary phase.

[0003] There is a 60cm~100cm long liquid outlet tube at the liquid outlet of the liquid chromatograph. When the liquid chromatograph is running, the staff generally uses two methods to receive the liquid released by the liquid outlet tube. The first method is to place multiple conical flasks on the table, insert the liquid outlet tube into a conical flask, and when the conical flask is full of liquid, the staff inserts the liquid outlet tube into the next conical flask; the second method is to fix the liquid outlet tube on the bracket, and the staff places a conical flask under the outlet of the liquid outlet tube. When the conical flask is full of liquid, the staff replaces the conical flask. There is a problem with both of the above methods: after the conical flask is full of liquid, it is necessary to manually move the liquid outlet tube or manually replace the conical flask, and automation is not achieved.

[0024] like Figure 1 , Figure 2 As shown, this embodiment provides a device for supplementing and receiving materials for conical bottles, including a storage rack 1, a tray 2, a bracket 3, and a travel mechanism 4.

[0025] Specifically, Figure 1~Figure 4 As shown, the storage rack 1 includes a flat plate 11, each side of the flat plate 11 is provided with two L-shaped plates 12, and the tray 2 is placed on the storage rack 1. The tray 2 includes a bottom plate 21, a rectangular frame 22 and a cover plate 23. The bottom plate 21 is square, and a column 211 is respectively arranged at its four right angles. Circular holes are arranged at the four right angles of the rectangular frame 22. The rectangular frame 22 is sleeved on the four columns 211 through the circular holes. The area enclosed by the rectangular frame 22 and the bottom plate 21 is used to place 16 conical bottles. The 16 conical bottles are distributed in 4 rows and 4 columns. The rectangular frame 22 acts as a fence. The cover plate 23 is provided with 16 limiting holes 231. The limiting holes 231 are used to limit the bottle mouths of the conical bottles so that the conical bottles are arranged neatly. The cover plate 23 is detachably assembled on the four columns 211.

The diameter of the base rod 2111 and the bottom diameter of the cone 2112 are consistent with the diameter of the circular hole, the top diameter of the cone 2112 is larger than the diameter of the top rod 2113, and the diameter of the top rod 2113 is consistent with the diameter of the insertion hole.

[0027] In this embodiment, the tray 2 is directly placed on the rack 1, and is not fixedly mounted on the rack 1. The purpose of this design is to facilitate the removal or placement of the tray 2, so as to transfer the conical bottle as a whole. The tray 2 itself is detachable and easy to assemble. The rectangular frame 22 is mounted on the four base rods 2111 through the circular holes, and the cover plate 23 is mounted on the four top rods 2113 through the plug holes.

[0028] Specifically, Figure 1 , Figure 5As shown, the bracket 3 includes a vertical plate 32 and a cylinder 33. One end of the cylinder 33 is vertically arranged on the vertical plate 32, and the other end of the cylinder 33 is provided with a horizontal ring 34. A plug 31 is placed in the ring 34. The plug 31 is an inverted cone shape, and the outer wall of the plug 31 is close to the inner wall of the ring 34. The material of the plug 31 is rubber, plastic or wood. A through hole 311 is provided in the center of the plug 31, which runs through itself from top to bottom. The through hole 311 is used to insert the liquid outlet pipe of the liquid chromatograph. The outlet pipe mouth is suspended below the plug 31. Since the length of the liquid outlet pipe is too long, the liquid outlet pipe can be wrapped around the cylinder 33.

[0029] Specifically, the travel mechanism 4 is arranged on the support plate, and the travel mechanism 4 is connected to the rack 1, and is used to move the rack 1 in the X and Y axis directions, and move the conical flask to the bottom of the through hole 311 in sequence, and the outlet pipe mouth is suspended below the through hole 311, and the conical flask is used to receive the liquid released by the outlet pipe.

[0030] like Figure 1 , Figure 7 , Figure 8 As shown, the travel mechanism 4 is specifically implemented as follows: it includes two motors, two screw rods, a guide rod 43, a regulating rod 44, two bevel gears and a moving frame 46, the first screw rod 421 is rotatably arranged in the moving frame 46, a slider is slidably arranged in the moving frame 46, the slider is threadedly matched with the first screw rod 421, the top of the slider is connected to the storage rack 1, one end of the first screw rod 421 passes through the moving frame 46 and is coaxially connected to the first bevel gear 451, six bases are arranged on the top of the support plate, the second screw rod 422, the guide rod 43 and the regulating rod 44 are arranged in parallel, the second screw rod 422 and the two ends of the regulating rod 44 are respectively rotatably connected to the corresponding bases, the two ends of the guide rod 43 are fixedly connected to the corresponding bases, the second screw rod 42 The thread penetrates the moving frame 46, the guide rod 43 slides through the moving frame 46, the first motor output shaft is connected to one end of the second screw rod 422, the second motor output shaft is connected to one end of the regulating rod 44, the side wall of the regulating rod 44 is provided with two convex strips, the second bevel gear 452 is sleeved on the regulating rod 44, and the two are slidably matched, the moving frame 46 is provided with a limit frame 461 at one end facing the first bevel gear 451, and the second bevel gear 452 is located in the limit frame 461. It should be noted that the limit frame 461 cannot hinder the rotation of the second bevel gear 452. When the moving frame 46 moves, the limit frame 461 is used to synchronously move the second bevel gear 452, so that the first bevel gear 451 and the second bevel gear 452 are always meshed.

[0031] The operating principle is as follows: the first motor is used to drive the second screw rod 422 to move the moving frame 46 along the X-axis, thereby moving the conical flask as a whole along the X-axis; the second motor is used to drive the regulating rod 44 to rotate the second bevel gear 452. Since the first bevel gear 451 is engaged with the second bevel gear 452, the first bevel gear 451 and the second screw rod 422 are rotated, and the second screw rod 422 causes the storage rack 1 and the tray 2 to move, thereby moving the conical flask as a whole along the Y-axis.

[0032] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
