Description

Technical Field

[0001] The utility model belongs to the technical field of gluing a sampling tube, in particular to a tube loading and gluing device. Background Art

[0002] In the field of clinical medicine, blood tests are increasingly used as a diagnostic tool. Separation gel is an important raw material used in sampling tubes. Its function is that the specific gravity of separation gel is between that of serum and blood cells. After the blood is precipitated by rotating centrifugation, the separation gel separates the serum and blood cells. Separation gel has high viscosity and is not easy to package at room temperature. Therefore, each sampling tube needs to be filled with gel.

[0003] In the existing technology, the separation glue is often added manually or semi-manually. Therefore, the existing technology only has glue adding technology but no efficient molding technology, which has problems such as low work efficiency and poor glue adding quality.

[0029] Example 1

[0030] Refer to the attached Figure 1-3 A pipe loading and gluing device of the present embodiment includes a frame 100, a heat preservation barrel 110 and a gluing assembly 200 installed on the frame 100, the gluing assembly 200 includes a lower glue part 210, a valve group 220, a manifold 230 and a gluing needle group 240, the glue in the heat preservation barrel 110 flows into the manifold 230 through the lower glue part 210, the valve group 220 is connected to the manifold 230, the gluing needle group 240 is installed below the manifold 230, one end of the infusion channel in the manifold 230 is connected to the lower glue part 210, and the other end is connected to the gluing needle group 240, the valve group 220 is connected to the middle part of the infusion channel and controls the on-off of the infusion channel.

[0031] The valve group 220 of this embodiment includes a valve body 221, on which are provided an installation channel 2211, a liquid inlet channel 2212, a liquid outlet channel 2213 and a liquid storage channel 2214. The installation channel 2211 runs through the valve body 221 from top to bottom, and the liquid storage channel 2214 is connected to the middle of the installation channel 2211. The liquid inlet channel 2212 and the liquid outlet channel 2213 are symmetrically arranged on the same side of the valve body 221 about the central axis of the liquid storage channel 2214 and are both connected to the installation channel 2211.

[0032] The valve group 220 of this embodiment also includes a combined sliding valve 222, a sleeve 223, a pressure plate plunger 224 and a ceramic rod 225. The upper and lower ports of the installation channel 2211 are both installed on the pressure plate plunger 224. A sleeve 223 is provided in the installation channel 2211. The sleeve 223 is provided with through holes corresponding to the liquid inlet channel 2212, the liquid outlet channel 2213 and the liquid storage channel 2214. The combined sliding valve 222 is installed in the sleeve 223 and one end extends out of the pressure plate plunger 224. The ceramic rod 225 is installed in the liquid storage channel 2214.

[0033] In this embodiment, a heating plate 226 is provided at the bottom of the valve body 221 , and a heat insulation plate 227 is installed below the heating plate 226 . The heating plate 226 is used to heat the valve body 221 .

[0034] In this embodiment, the combined sliding valve 222 and the ceramic rod 225 are respectively provided with a cylinder and a displacement motor at one end away from the valve body 221 for displacement control. Sealing rings are provided in the installation channel 2211 and the liquid storage channel 2214. The structure of this design adopts seven bars to control the combined sliding valve 222, so that its response and regulation are rapid. The displacement motor drives the ceramic rod 225 to move, which belongs to the principle of the screw slider structure, and will not be elaborated here. The accompanying drawings have a corresponding structure. This driving form can flexibly regulate the elements, so that the glue addition to the sampling tube is uniform and stable.

[0035] The glue-adding needle group 240 of this embodiment includes a positioning block 241, a mouthpiece 242, a glue-adding needle tube 243 and a needle 244. The positioning block 241 is installed on the frame 100 through a connecting plate. One end of the glue-adding needle tube 243 is connected to the liquid outlet channel 2213 through the mouthpiece 242, and the needle 244 is installed on the other end. The glue-adding needle tube 243 passes through the positioning block 241.

[0036] Working principle: the glue liquid is filled in the insulation barrel 110, and flows into the conduit 230 through the lower glue part 210. First, the combined slide valve 222 moves upward to connect the liquid inlet channel 2212 with the liquid storage channel 2214. The glue liquid passes through the liquid inlet channel 2212 and the sleeve 223 in turn and finally flows into the liquid storage channel 2214. Then, the combined slide valve 222 descends, and the liquid storage channel 2214 is connected with the liquid outlet channel 2213. The ceramic rod 225 is pushed in, so that the glue liquid flows into the liquid outlet channel 2213 and finally flows to the glue needle group 240.

[0037] The storage space size of the liquid storage channel 2214 is controlled by controlling the displacement of the ceramic rod 225, thereby controlling the overall amount of glue added. It should be noted that the glue liquid in the insulation barrel 110 may cool down after entering the valve body 221, so a heating plate 226 is provided to heat and maintain its temperature.

[0038] The above structure is highly dismantlable and convenient for later repair and maintenance.

[0039] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
