Description
Technical Field
[0001] This utility model belongs to the field of chemical product sampling technology, and relates to a sampling auxiliary device suitable for chemical products. Background Technology
[0002] Existing methods for adjusting sampling of multiple chemical products mainly suffer from uneven sampling, poor representativeness, cross-contamination during sampling, and low sampling efficiency. These shortcomings arise from factors such as unreasonable sampling equipment design, insufficient operator skills, inadequate environmental control, and non-standard sampling procedures. For example, improperly designed sampling equipment may result in insufficient mixing of samples during collection, thus failing to accurately reflect the overall material properties; lack of professional training among operators may introduce human error during sampling; inadequate environmental control may affect sample stability due to changes in temperature, humidity, and other environmental factors; and non-standard sampling procedures may lead to changes in sample quality during collection, preservation, and transportation. Therefore, there is an urgent need for a suitable sampling auxiliary device for chemical products to address these issues. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sampling auxiliary device suitable for chemical products, and to solve the problems mentioned in the background technology.

The front side of the top beam is provided with a set of movable seats for adjusting the left and right positions of the sample suction head. The movable seat includes a main body and a sample suction head. The right side of the main body has a right-angled trapezoidal structure in cross-section. The inner rear end of the main body is provided with a set of fittings for movable limiting engagement with the upper guide rail.
[0005] The lower rear end of the main body is provided with a set of two inserts. The middle position of the rear end of the main body is provided with a set of upper limit inserts for connection with the main lead screw limit. The upper end of the main body is provided with a set of electric cylinders for adjusting the front lifting seat to move up and down. The lower end of the electric cylinder is a telescopic end, and the front side of the lower end of the telescopic end is connected and fixed to the front lifting seat.

The lower end of the negative pressure pump is provided with a set of sample suction heads for aspirating and sampling the sample. First, the staff places the multiple samples to be collected on the upper end of the sample carrier plate. Then, the staff starts the lead screw motor to control the rotation of the main lead screw, which drives the movable seat to move left and right, so that the position of the sample suction head corresponds to the vertical height position of a single sample, and the position of the sample suction head is adjusted to correspond to the sample. Then, the height position of the sample suction head is adjusted by using the electric cylinder, so that the staff can easily sample the sample.
[0006] In a preferred embodiment, the front side of the top beam is provided with two sets of upper guide rails for maintaining the movement of the movable seat. The upper guide rail is movably engaged with the first insert, and the lower guide rail is movably engaged with the second insert.
[0007] In a preferred embodiment, the upper limit stop is provided with a set of main screws for driving the movable seat to move left and right, and a set of screw motors for providing active power to the right side of the main screws is provided.
[0008] In a preferred embodiment, the left side of the main lead screw is provided with an upper positioning seat for providing rotational limit for the main lead screw, and the lower end of the sample suction head is provided with a sample carrier plate for centrally supporting multiple samples.
[0009] In a preferred embodiment, the lower ends of the left and right sides of the sample carrier plate are provided with a number of lower inserts for guiding its movement, and the lower end of each of the several sets of lower inserts is provided with a set of lower guide rails for fitting into it.
[0010] In a preferred embodiment, the lower guide rail is provided in two sets, and a set of lower limit inserts for guiding the movement of the sample carrier plate is provided at the middle position of the lower end.
[0011] In a preferred embodiment, the lower limit insert is provided with a set of guide rods for guiding its movement. The guide rods are provided with a set of lower positioning seats on the front and rear sides for limiting their position. When the staff is sampling the chemical product, the staff can also move the sample carrier to adjust its front and rear position, thereby facilitating the collection of chemical product samples.
[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the staff places multiple samples to be collected on the upper part of the sample carrier plate, and then the staff controls the main screw to rotate by starting the lead screw motor, which drives the movable seat to move left and right, so that the position of the sample suction head corresponds to the single sample and adjusts its vertical height position, and adjusts the position of the sample suction head corresponding to the sample. Then, the height position of the sample suction head is adjusted by using an electric cylinder, which makes it easier for the staff to collect the sample.
[0013] When staff are sampling chemical products, they can also move the sample carrier plate to adjust its position, which makes it easier for staff to collect chemical product samples. Attached Figure Description
