Description

Technical Field

[0001] The utility model belongs to the technical field of conveying, in particular to a sample feeding and conveying device for an automatic sample preparation system. Background Art

[0002] The automatic sample preparation system realizes the automation of sample preparation with the help of automatic sample preparation equipment and robots, and is widely used in raw material and fuel testing fields such as steel mills, coal mines, and power plants.

[0003] Existing sample barrel conveyors mostly use roller conveyors as sample barrel conveying carriers. In order to realize the circular transportation of sample barrels, four roller conveyors are mostly used in combination. Each roller conveyor is equipped with a reduction motor, and multiple reduction motors are used for control. In addition, a barrel blocking cylinder and a positioning cylinder are added to realize the positioning of the sample barrel to cooperate with the robot to grab the sample barrel.

[0004] Although it can realize the automation of sample feeding, it also has certain defects: multiple reducers are required to work together to realize the circulation of sample barrels, and the control is relatively complicated; due to too many mechanisms, the positioning accuracy is low; the roller of the roller conveyor is in direct contact with the sample barrel, causing wear of the roller and the sample barrel. The roller conveyor is equipped with many rollers, and the probability of roller damage is high. The equipment is shut down for replacement, which delays the sample preparation production efficiency.

[0005] Therefore, the utility model provides a sample feeding and conveying device for an automatic sample preparation system to solve the problems raised in the above background technology. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sample feeding and conveying device for an automatic sample preparation system comprises an equipment support frame, a support base plate is installed on the equipment support frame, and a circular track is arranged on the support base plate; a plurality of sample barrel trays are movably arranged in the circular track, and chain driving mechanisms are arranged at both ends of the inner side of the circular track, and the sample barrel trays are driven to move by the chain driving mechanism; a detection support frame is arranged above the support base plate, and a code reader and a sample barrel detection switch are installed on the detection support frame, and a sample barrel position positioning switch is also installed on one side of the support base plate.

[0008] A further solution: an active roller group and a passive roller group which are mutually transmission-connected are installed at the bottom of the sample barrel tray, and the sample barrel tray is installed above the circular track through the active roller group and the passive roller group.

[0009] A further solution: a roller connecting plate is installed on the active roller group, and the active roller group is connected to the chain driving mechanism through the roller connecting plate.

[0010] A further solution: the chain drive mechanism comprises a driving sprocket group and a driven sprocket group, and the driving sprocket group and the driven sprocket group are connected by chain transmission to form a ring.

[0011] A further solution: the chain is provided with a plurality of chain connecting pins, which are connected to the sample barrel tray via the chain connecting pins.

[0012] A further solution is that a servo reduction motor is provided below the chain driving mechanism, and an output end of the servo reduction motor is connected to a driving sprocket set through a coupling.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The movement of the sample barrel tray on the circular track is precisely controlled by the servo reduction motor and the chain drive mechanism. The sample barrel is placed above the sample barrel tray, and the sample barrel position positioning switch is used to achieve precise positioning of the sample barrel. The sample barrel is placed above the sample barrel tray and there is no relative movement during operation. A driving sprocket group and three driven sprocket groups are connected by a chain to form a ring. The chain pulls the driving roller group and the follower roller group to slide on the circular track, so that the sample barrel tray circulates on the circular guide rail. After the sample barrel is filled with samples, the empty barrel returns to the starting position, realizing the cyclic sampling of the sample barrel in the sampling link of the automatic sample preparation system.
