Description

[Technical field]

[0001] The invention relates to the technical field of laboratory instruments, in particular to the technical field of a test tube cleaning device. [Background technology]

[0002] Test tubes are a common instrument in chemical laboratories. They are mainly used as chemical reaction containers for small amounts of reagents and are used at room temperature or when heated. Generally speaking, test tubes can be divided into ordinary test tubes, test tubes with supports, centrifuge test tubes, and many other types. The main uses of test tubes are as follows: holding liquid or solid reagents; heating a small amount of solid or liquid; preparing a small amount of gas reactor; collecting a small amount of gas; dissolving a small amount of gas, liquid or solid solutes; as a container for centrifugation; used as a reaction container for a small amount of reagents and are used at room temperature or when heated.

[0003] After the test tube is used, there will inevitably be some residues attached to the inner wall of the test tube, which needs to be cleaned. At present, most people clean the residues on the inner wall of the test tube manually. First, people hold a test tube brush in one hand and the test tube in the other hand, and then insert the test tube brush into the test tube for repeated cleaning, which results in a lot of labor for the cleaning personnel and low work efficiency. [Summary of the invention]

[0004] The purpose of the present invention is to solve the problems in the prior art and to provide a test tube cleaning device that can reduce manual labor and improve work efficiency.

[0005] To achieve the above-mentioned purpose, the present invention proposes a test tube cleaning device, including a scraping device and a conveying device located below the scraping device, the scraping device including a driving mechanism I and a plurality of scraping mechanisms driven up and down by the driving mechanism I, the scraping mechanism including a foldable scraper mechanism and a driving mechanism II for driving the scraper mechanism to fold or unfold, the conveying device including a driving mechanism III and an arranging mechanism driven forward and backward by the driving mechanism III, the arranging mechanism drives the test tubes arranged thereon to enter the bottom of the corresponding scraping mechanism in sequence.

[0006] Preferably, the driving mechanism I includes an electric push rod I and a mounting seat provided on the driving end of the electric push rod I.

[0007] Preferably, the scraping mechanism further comprises a support rod and a U-shaped frame arranged at the lower end of the support rod, and the U-shaped frame is provided with a scraper mechanism and a driving mechanism II.

[0008] Preferably, the driving mechanism II comprises a cylinder, a connecting seat and two connecting rods, the driving end of the cylinder is provided with a connecting seat, and one end of the connecting rod is movably connected to the connecting seat.

[0009] Preferably, the scraper mechanism comprises two rotating bodies and elastic scrapers arranged on the two rotating bodies, the two rotating bodies are symmetrically arranged at the lower end of the U-shaped frame, and the two rotating bodies are movably connected to the other end of the corresponding connecting rod respectively.

[0010] Preferably, the elastic scraper is annular in shape.

[0011] Preferably, the rotating body is semicircular in shape, a cavity is provided in the rotating body, a plurality of water spray outlets connected to the cavity are provided on the arcuate side of the rotating body, water inlets connected to the cavity are provided on the rotating body, and the water inlets are connected to the water supply pipe.

[0012] Preferably, the driving mechanism III comprises a disk body and an electric push rod II arranged at the rear end of the disk body, and a drainage port is arranged at the bottom of the disk body.

[0013] Preferably, the arrangement mechanism comprises an arrangement plate, on which are arranged a plurality of rows of placement holes, each row of placement holes corresponds to a scraping mechanism, and a fixing mechanism is provided at the lower end of each placement hole.

[0014] Preferably, the fixing mechanism comprises an annular body and elastic clamping arms which are circumferentially spaced apart on the annular body.

[0015] Beneficial effects of the present invention: The present invention drives the arranging mechanism through the driving mechanism III, and the arranging mechanism drives the test tubes arranged thereon to enter the bottom of the corresponding scraping mechanism in turn. The scraping mechanism is driven by the driving mechanism I to enter the corresponding test tube and perform up and down scraping and washing operations. Compared with the prior art, it can reduce manual labor and improve work efficiency.

[0016] Since the brush is soft, the friction between the inner wall of the test tube and the brush is smaller. When the inner wall of the test tube is attached with residues such as grease, organic matter, etc. that are difficult to brush off, the cleaning effect is poor. The present application uses an elastic scraper 1212 to perform a seamless scraping operation on the inner wall of the test tube, and supports the elastic scraper through a rotating body, so that the elastic scraper has better friction with the inner wall of the test tube, thereby achieving a better cleaning effect.

[0017] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.
