Abstract
Description
Technical Field
[0001] The utility model relates to a labeling device, in particular to a labeling device for pre-installed reagent reaction tubes. Background Art
[0002] A labeling machine is a machine that applies labels to products or packaging. Reaction tube labeling machines automatically apply glue to labels and apply them to the circumference of the reaction tube. These machines improve product labeling efficiency, ensuring accurate placement, high quality, and high stability. They eliminate issues such as inefficient manual labeling, skewed labeling, uneven glue thickness, and wrinkles. They effectively reduce glue waste, lower labor costs, enhance the aesthetics of product labeling, and improve overall product competitiveness.
[0003] The current labeling machine for reaction tubes does not take into account the scenario of pre-loaded reagents. The current labeling machine for reaction tubes with pre-loaded reagents actually uses a labeling machine that can label the circumferential surface. After the label is affixed, the pre-loaded reagent reaction tube is transported by a conveyor roller group to the top of the receiver (such as a storage basket, a turnover basket), and then freely falls into the receiver. When the reaction tube is pre-loaded with competent cells, the free fall into the receiver has a certain adverse effect on the activity of the competent cells. When the reaction tube is pre-loaded with liquid reagents, the free fall into the receiver will make the pre-loaded liquid reagents uneven, especially when oily substances are distributed in it. This unevenness can even be observed with the naked eye.
[0004] Therefore, there is an urgent need in the art for a labeling device for pre-filled reagent reaction tubes. Utility Model Content
[0005] The first aspect of this utility model is to provide a labeling device for pre-loaded reagent reaction tubes to address the technical problem of existing reaction tube labeling devices causing pre-loaded reagent reaction tubes to free fall into a container, impacting product quality. This utility model solves this technical problem and achieves the technical advantages of this utility model through the following technical solutions.
[0006] A labeling device for pre-loaded reagent reaction tubes includes a labeling device body, the labeling device body includes a conveyor roller group mounting frame and a conveyor roller group, the conveyor roller group is installed on the conveyor roller group mounting frame, the conveyor roller group transports the labeled pre-loaded reagent reaction tubes to a receiver, the receiver is located below the conveyor roller group, the labeling device for pre-loaded reagent reaction tubes also includes a chute, the upper end of the chute is installed at the bottom of the conveyor roller group mounting frame, and the lower end of the chute is located above the bottom plate of the receiver.
[0007] Furthermore, the chute includes a chute body, a buffer layer, and a flexible smooth surface layer, wherein the buffer layer is paved on the upper surface of the chute body, and the flexible smooth surface layer is paved on the upper surface of the buffer layer. Preferably, the chute body is a stainless steel chute body; the buffer layer is a sponge layer with a thickness of 0.2-1 cm; the flexible smooth surface layer is an aluminum foil layer or a plastic layer, the aluminum foil layer has a thickness of 0.01-0.2 mm, and the plastic layer has a thickness of 2 mm-3 mm. The inventors of this case have experimented with directly using a stainless steel chute and found that the pre-loaded reagent reaction tube will still have an impact when it falls from the conveying roller group to the stainless steel chute, because the pre-loaded reagent reaction tube is made of plastic and is relatively lightweight. After the impact, it will bounce along the stainless steel chute multiple times and fall into the receiver or fall to the ground, and there is still a certain probability that it will affect the product quality. The inventors also experimented with adding a buffer layer, such as sponge, to the stainless steel chute. However, they found that this could cause the pre-loaded reagent reaction tubes to become stuck in the chute (because the lids and the connection between the lids and tubes are not perfectly round), or even get stuck between the conveyor rollers and the chute. Finally, the inventors added a flexible, smooth surface layer, such as aluminum foil or plastic, which completely resolved the technical issues. The inventors also tried adding a layer of plastic film, but this did not resolve the issue.
[0008] Based on any of the above technical solutions, preferably, the angle of the chute is 30°-45°. Based on any of the above technical solutions, further, the bottom plate of the storage container includes a bottom plate body and a cushioning pad, and the cushioning pad is disposed on the bottom plate body. Preferably, the cushioning pad is sponge and has a thickness of 1 cm-3 cm.
[0009] Based on any of the above technical solutions, preferably, the receiver is located obliquely below the conveying roller group.
[0010] Based on any of the above technical solutions, preferably, the labeling device body of the labeling device for pre-filled reagent reaction tubes is a labeling machine.
[0011] The second aspect of the present invention aims to provide a chute to solve the technical problem that when the chute of the current reaction tube labeling device is used to label pre-loaded reagent reaction tubes, the pre-loaded reagent reaction tubes freely fall into the receiver and affect product quality.
[0012] A chute includes a chute body, and is characterized in that the chute also includes a buffer layer and a flexible smooth surface layer, the buffer layer is paved on the upper surface of the chute body, and the flexible smooth surface layer is paved on the upper surface of the buffer layer.
[0013] Preferably, the chute body is a stainless steel chute body; the buffer layer is a sponge layer with a thickness of 0.2-1 cm; the flexible and smooth surface layer is an aluminum foil layer or a plastic layer, the aluminum foil layer has a thickness of 0.01-0.2 mm, and the plastic layer has a thickness of 2 mm-3 mm.
[0014] This new labeling device for pre-loaded reagent reaction tubes allows the tubes to drop through a chute into a receptacle, eliminating product quality issues associated with free fall into the receptacle. The chute further comprises a chute body, a buffer layer, and a flexible, smooth surface layer, further addressing product quality issues caused by the tubes impacting the chute upon falling, as well as the technical issues of the tubes becoming stuck in the chute or becoming stuck between the conveyor roller assembly and the chute. The device can operate continuously for at least 24 hours without these issues, and in actual testing, these issues have never occurred during extended periods of idle work.

[0018] The present invention will be described below in conjunction with specific embodiments.
[0019] See also Figure 1 . A labeling device for pre-loaded reagent reaction tubes, including a labeling device body 1, such as a labeling machine. The labeling device body 1 includes a conveying roller group mounting frame 11 and a conveying roller group 12. The conveying roller group 12 is installed on the conveying roller group mounting frame 11. The conveying roller group 12 transports the labeled pre-loaded reagent reaction tube 4 to the receiver 3. The receiver 3 is located below the conveying roller group 12. The labeling device for pre-loaded reagent reaction tubes also includes a chute 2. The upper end of the chute 2 is installed at the bottom of the conveying roller group mounting frame 11, and the lower end of the chute 2 is located above the bottom plate 31 of the receiver 3. The angle of the chute 2 is 30°-45°. The receiver 3 is located obliquely below the conveying roller group 12. The receiver 3 can also be used as a separate product and is not regarded as part of the labeling device for pre-loaded reagent reaction tubes. Regardless of whether the receiver 3 is part of the labeling device for pre-loaded reagent reaction tubes, it is covered under this specific embodiment and is within the scope of protection required by the present utility model.
[0020] See also Figure 2. The chute 2 includes a chute body 21, a buffer layer 22, and a flexible smooth surface layer 23. The buffer layer 22 is paved on the upper surface of the chute body 21, and the flexible smooth surface layer 23 is paved on the upper surface of the buffer layer 22. Preferably, the chute body 21 is a stainless steel chute body; the buffer layer 22 is a sponge layer with a thickness of 0.2-1cm; the flexible smooth surface layer 23 is an aluminum foil layer (with a thickness of 0.01mm-0.2mm) or a plastic layer (with a thickness of 2mm-3mm). The inventor of this case has experimented with directly using a stainless steel chute and found that the pre-loaded reagent reaction tube 4 will still have an impact when it falls from the conveying roller group 12 to the stainless steel chute, because the pre-loaded reagent reaction tube 4 is made of plastic and is relatively light. After the impact, it will bounce along the stainless steel chute multiple times and fall into the receiver 3 or fall to the ground. There is still a certain probability that it will affect the product quality. The inventors therefore experimented with adding a cushioning layer, such as sponge, to the surface of the stainless steel chute. However, they found that this again caused the pre-reagent reaction tube 4 to become stuck in the chute 2 (because the cover and the connection between the cover and the tube are not completely round), and even become stuck between the conveyor roller assembly 12 and the chute 2. Finally, the inventors added a flexible, smooth surface layer, such as aluminum foil (0.01mm-0.2mm thick) or plastic (2mm-3mm thick), which completely resolved the related technical issues. The inventors also tried adding a layer of plastic film, but this did not resolve the problem.
[0021] See also Figure 1 、 3 The bottom plate 31 of the storage container 3 includes a bottom plate body 311 and a cushioning pad 312, which is arranged on the bottom plate body 311. The cushioning pad 312 is a sponge with a thickness of 1cm-3cm. The storage container 3 is commonly a storage basket or a turnover basket, preferably a food-grade plastic turnover basket.
[0022] During use, the labeled pre-loaded reagent reaction tube 4 is transported by the conveying roller group 12 and falls into the chute 2. Because the chute 2 includes a chute body 21, a buffer layer 22, and a flexible smooth surface layer 23, there will be no bouncing phenomenon, and the reaction tube 4 can smoothly slide down along the flexible smooth surface layer 23 of the chute 2 without accumulation, and will not get stuck between the conveying roller group 12 and the chute 2. After sliding down, the pre-loaded reagent reaction tube 4 falls into the receiver 3. The bottom plate 31 of the receiver 3 is provided with a buffer pad 312, which further solves the problem of falling impact affecting product quality. In actual measurements, even if the receiver 3 with the buffer pad 312 is not used, as long as the chute 2 of the present invention is used, the technical problem to be solved by the present invention can be solved within the conventional angle range of the chute 2.
[0023] The present invention's labeling device for pre-loaded reagent reaction tubes allows pre-loaded reagent reaction tubes 4 to drop through a chute 2 into a receiver 3, eliminating product quality issues caused by free fall into the receiver 3. The chute 2 further includes a chute body 21, a buffer layer 22, and a flexible, smooth surface layer 23. This further addresses product quality issues caused by the pre-loaded reagent reaction tubes 4 hitting the chute 2 during their fall, as well as the technical issues of the pre-loaded reagent reaction tubes 4 becoming stagnant in the chute 2 or becoming stuck between the conveyor roller assembly 12 and the chute 2. The device can operate continuously for at least 24 hours without these issues. In actual measurements, these issues have never occurred during extended periods of idle work.
[0024] The chute 2 of the present invention can also be used as a product alone. Its structure is as described above and will not be described in detail.
