Description

Technical Field

[0001] The utility model relates to the technical field of test paper processing and production, in particular to a pretreatment device for colloidal gold pads and sample pads. Background Technique

[0002] Colloidal gold is a commonly used labeling technique, which is a new type of immunolabeling technique using colloidal gold as a tracer marker for antigens and antibodies. It has unique advantages and has been widely used in various biological researches in recent years. Almost all immunoblotting techniques used in clinical practice use its labeling.

[0003] As a carrier of colloidal gold, the gold pad / sample pad will be prepared with treatment liquid, soaked, dried, cut and other operations during pretreatment; at present, the pretreatment process of the gold pad / sample pad on the market is carried out separately, which not only wastes time but also has low production efficiency. Therefore, it is very necessary to design a device that can automatically complete the pretreatment of the gold pad / sample pad to improve the production efficiency of colloidal gold products. Summary of the Invention

[0004] The purpose of the utility model is to provide a pretreatment device for colloidal gold pads and sample pads in view of the defects of the prior art.

[0005] To achieve the above purpose, the utility model can adopt the following technical solutions:

[0006] The pretreatment device for colloidal gold pads and sample pads of the utility model is characterized in that: it includes a support, on which an infiltration unit, a drying unit and a cutting unit are arranged in sequence from left to right;

[0007] Among them, the infiltration unit includes an infiltration tank with an arc-bottom structure. Along the arc surface direction of the bottom of the infiltration tank, a plurality of conveying rollers are arranged at intervals. Above each conveying roller, a retaining roller is correspondingly arranged. An infiltration channel for the gold pad / sample pad to pass through is formed between the retaining roller and the conveying roller;

[0008] The drying unit includes a drying box, on which a drying channel is horizontally arranged. The inlet end of the drying channel is connected to the discharge end of the infiltration unit, and a heating fan is arranged in the drying channel;

[0009] The cutting unit includes a cutting seat connected to the outlet end of the drying channel. Along the conveying direction of the gold pad / sample pad, a pair of supporting rollers are horizontally arranged at intervals on the cutting seat. Above the gap between the two supporting rollers, an electric cutting knife moving vertically is arranged.

[0010] Further, a first guide roller facing the feed end of the infiltration channel and a second guide roller facing the discharge end of the infiltration channel are provided at the notch of the infiltration tank. The gold pad / sample pad moving horizontally is redirected by the first guide roller and pushed into the infiltration tank, and then the gold pad / sample pad discharged from the infiltration tank is redirected again by the second guide roller and sent out of the infiltration unit horizontally.

[0011] Further, the conveying roller is an electric waterproof roller hermetically passing through the infiltration tank, so as to ensure the normal operation of the conveying roller in the infiltration tank. In addition, to increase the friction between the conveying roller and the gold pad / sample pad, the roller surface of the conveying roller can be set as an anti-slip rough surface.

[0012] Further, to ensure the effective drying of the gold pad / sample pad, a plurality of squeezing rollers can be arranged at intervals along the conveying direction of the gold pad / sample pad in the drying channel.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, the directional indications will also change accordingly.

[0020] In addition, in the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one such feature.

[0021] As Figure 1 , 2 As shown, the colloidal gold gold pad and sample pad pretreatment device of the present utility model includes a support 1, on which an infiltration unit, a drying unit, and a cutting unit are sequentially arranged from left to right.

[0022] Specifically, the infiltration unit includes an infiltration tank 2 with an arc-bottom structure. Along the arc surface direction of the bottom of the infiltration tank 2, a plurality of conveying rollers 3 are arranged at intervals. To ensure the normal operation of the conveying rollers 3 in the infiltration tank 2, the conveying rollers 3 should be electric waterproof rollers that are hermetically penetrated in the infiltration tank 2; above each conveying roller 3, a retaining roller 4 is correspondingly arranged one by one. Each retaining roller 4 is parallel to the corresponding conveying roller 3, and the distance between all retaining rollers 4 and the corresponding conveying rollers 3 is kept consistent, so as to form an arc-shaped infiltration channel 5 for the gold pad / sample pad to pass through in the infiltration tank 2. To increase the friction when the conveying roller 3 contacts the gold pad / sample pad, the roller surface of the conveying roller 3 can also be set as a non-slip rough surface. Of course, a plurality of oblique grooves or oblique ridges can also be evenly distributed on the roller surface of the conveying roller 3, so that its roller surface is a non-planar surface to increase friction. In addition, a first guiding roller 6 facing the feeding end of the infiltration channel 5 and a second guiding roller 7 facing the discharging end of the infiltration channel 5 can be arranged at the notch of the infiltration tank 2. The axial directions of the first guiding roller 6 and the second guiding roller 7 are the same as the axial direction of the conveying roller 3. The gold pad / sample pad is pressed by the first guiding roller 6 to change the direction of the horizontally moving gold pad / sample pad and push it into the infiltration channel 5 in the infiltration tank 2. The gold pad / sample pad pushed out of the infiltration tank 2 along the infiltration channel 5 is pressed by the second guiding roller 7 to change the direction again and be sent out of the infiltration unit in a horizontal posture.

[0023] The drying unit includes a drying box 8, on which a drying channel 9 is horizontally arranged. The inlet end of the drying channel 9 is connected to the discharge end of the infiltration unit. To enable the gold pad / sample pad to easily pass through the drying channel 9, the bottom surface of the drying channel 9 can also be set as a conveyor belt or a row of rotating rollers arranged at uniform intervals. A heating blower 10 is arranged in the drying channel 9, which is composed of a blower that vertically blows air downward on the top wall of the drying channel 9 and electric heating wires arranged directly below the blower, and can blow hot air into the drying channel 9 to complete the drying of the gold pad / sample pad. In addition, to ensure that the gold pad / sample pad passing through the drying channel 9 can complete the drying operation more efficiently, a plurality of pressing rollers 11 can also be arranged at intervals along the conveying direction of the gold pad / sample pad in the drying channel 9. The vertical distance between the bottom surface of the pressing roller 11 and the bottom surface of the drying channel 9 should be slightly less than the thickness of the gold pad / sample pad, so as to be able to squeeze the gold pad / sample pad fed into the drying channel 9 through the pressing roller 11, quickly discharge the infiltration liquid in the gold pad / sample pad, and make the drying more efficient.

[0024] The cutting unit includes a cutting seat 12 connected to the outlet end of the drying channel 9. On the cutting seat 12, a pair of supporting rollers 13 are horizontally arranged at intervals along the conveying direction of the gold pad / sample pad. Above the gap between the two supporting rollers 13, an electric cutting knife 14 that moves vertically is arranged. The lower edge of the electric cutting knife 14 is a cutting edge. The electric cutting knife 14 has a first position where it moves upward until the cutting edge is away from the supporting rollers 13, and a second position where it moves downward until the cutting edge is between the two supporting rollers 13. And when the electric cutting knife 14 moves upward to the first position, the vertical distance between the lower edge of the cutting edge and the two supporting rollers 13 should be greater than the thickness of the gold pad / sample pad to ensure that the gold pad / sample pad can pass horizontally.

[0025] In addition, to facilitate the control of the entire pretreatment device, a control panel 15 for adjusting the running speed of the conveying roller 3, controlling the drying temperature of the heating blower 10, and controlling the cutting frequency of the electric cutting knife 14 should also be arranged on the support 1. The control panel 15 is a touch screen panel.

[0026] During use, first pour the prepared pretreatment liquid into the infiltration tank 2, and the pretreatment liquid just needs to cover the infiltration channel 5; then horizontally push the strip-shaped gold pad / sample pad that needs to be pretreated and is connected as a whole to the side of the infiltration tank 2 of the infiltration unit away from the drying unit through the conveying device. When the gold pad / sample pad encounters the first guide roller 6, it will change its angle under the pressing action of the first guide roller 6, and then move downward into the infiltration channel 5 between the conveying roller 3 and the retaining roller 4. While completing the infiltration, it continues to move driven by the conveying roller 3. When the infiltrated gold pad / sample pad encounters the second guide roller 7, it will adjust its angle again under the pressing action of the second guide roller 7, and then be horizontally pushed out of the infiltration unit and enter the drying channel 9 of the drying unit; in the drying channel 9, the gold pad / sample pad is squeezed by the squeezing roller 11 to quickly discharge the infiltration liquid, and at the same time, under the continuous drying action of the heating fan 10, the gold pad / sample pad completes the drying operation when it is horizontally pushed out of the drying channel 9; the dried gold pad / sample pad moves to the two supporting rollers 13 of the cutting unit, so that the electric cutter 14 completes the cutting and segmentation of the gold pad / sample pad at a fixed frequency. The entire pretreatment device can easily complete the continuous infiltration, drying, cutting and segmentation of the gold pad / sample pad, reduce cumbersome operations, optimize the operation steps, realize the automatic processing of the gold pad / sample pad, save the pretreatment time of the gold pad / sample pad, and thus improve the production efficiency of the colloidal gold product.
