Description

Technical Field

[0001] The utility model relates to the technical field of gel plate manufacturing devices, in particular to an agarose gel sheet manufacturing device. Background Art

[0002] There are currently two directions for film production:

[0003] 1) Production line production requires a large production site and many equipment (roller press, conveyor belt, cutter, coater, etc.). Advantages: uniform coating, controllable thickness and flatness. Disadvantages: once the machine is turned on, the output is large and the material is wasted. It is suitable for mass production, but not suitable for R&D and small laboratory customization.

[0004] 2) Manual small batch production can meet the needs of R&D and small laboratories, but it is impossible to achieve consistency in the coating of each film. The uneven coating of the film will lead to data deviation when running the electrophoresis test.

[0005] In summary, this product can meet the diversified use in small-scale laboratories, small batches and research and development of adhesive formulas, and can meet the requirements of the smoothness of the adhesive inside the finished product and the consistency between adhesives. Utility Model Content

[0006] In view of this, in order to solve the technical problem of uneven thickness of agarose gel sheets in the prior art, the utility model provides an agarose gel sheet production device, which ensures the flatness of the gel sheet through a negative pressure joint, thereby ensuring the uniform thickness of the produced agarose gel sheet. The agarose gel sheet produced by the utility model has a uniform thickness.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An agarose gel sheet production device, comprising:

[0009] A platform having a prefabricated groove with a constant groove depth;

[0010] A rubber sheet, which is used to be placed in the prefabricated groove;

[0011] A negative pressure joint is used to provide negative pressure in the prefabricated groove and to fix and level the rubber plate.

[0012] Preferably, it also includes:

[0013] Adjustable foot pads are used to adjust the level of the platform.

[0014] Preferably, the adjustment foot pads are rubber foot pads.

[0015] Preferably, prefabricated grooves are provided on the front and back sides of the platform.

[0016] Preferably, the number of prefabricated grooves on the front side of the platform is 4.

[0017] Preferably, the number of prefabricated grooves on the back side of the platform is 4.

[0018] Preferably, the thickness of the rubber sheet placed in the prefabricated groove on the front side of the platform is 0.6 mm.

[0019] Preferably, the thickness of the rubber sheet placed in the prefabricated groove on the back side of the platform is 0.7 mm.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] The utility model provides negative pressure for the rubber plate through the negative pressure joint, and the rubber plate is fixed in the prefabricated groove. The negative pressure joint ensures the flatness of the rubber plate, thereby ensuring the uniform thickness of the agarose gel sheet produced. The thickness of the agarose gel sheet produced by the utility model is uniform, and the negative pressure joint can make the rubber plate highly flat.

[0022] Since the gel is in liquid state above 60°C and has strong fluidity, it needs to be poured at a temperature greater than 60°, and scraped to remove the excess, maintaining the flatness. When the temperature drops below 30°C, it will form a gel-like and jelly-like state and be adsorbed on the rubber sheet. At this time, it can be taken out and stored without changing the height and shape due to a slight tilt.

[0023] The agarose gel sheet production device provided by the utility model is suitable for small-batch production in laboratories, saves site space, is miniaturized, and has a fast, simple and convenient production process. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "top / bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] like Figure 1-2 As shown, the utility model provides an agarose gel sheet manufacturing device, comprising: a platform 2, on which there are prefabricated grooves with a constant groove depth, the material of which is preferably 6061 aluminum alloy, preferably prefabricated grooves are provided on the front and back of the platform 2, and more preferably, the number of prefabricated grooves on the front and back is 4;

[0031] The rubber sheet 1 is used to be placed in the prefabricated groove. The material is preferably plastic PE material. The thickness of the rubber sheet placed in the prefabricated groove on the front of the platform 2 is preferably 0.6 mm, and the thickness of the rubber sheet placed in the prefabricated groove on the back of the platform 2 is 0.7 mm. According to actual needs, the rubber sheet 1 can be placed in the 4 prefabricated grooves on the front or back of the platform 2 to make different numbers of rubber sheets, such as Figure 1 As shown, only one rubber sheet 1 is placed in the prefabricated groove;

[0032] The negative pressure connector 3 is used to provide negative pressure in the prefabricated groove, and is used to fix and flatten the rubber sheet 1. Preferably, a syringe is connected to a hose to provide negative pressure for the rubber sheet. Negative pressure is formed between the rubber sheet 1 and the prefabricated groove through the negative pressure connector, and the rubber sheet 1 is fixed and flattened under the action of atmospheric pressure. The four corners or edges of the film may be uneven (warping). Under the tension of a little water and with the negative pressure adsorption of the four corners, the film can be fixed flat on the board, which plays a role in the uniformity and flatness of the glue coating.

[0033] In the utility model, it also includes:

[0034] The adjusting foot pad 4 is used to adjust the flatness of the platform 2, preferably a rubber foot pad. The adjusting foot pad 4 is preferably screwed to the platform. The horizontality of the platform 2 is adjusted by rotating the adjusting foot pad 4 clockwise or counterclockwise to make the platform 2 level. If it is not level, the liquid gel cannot adhere to the rubber plate at the same height.

[0035] The working principle of the utility model is as follows:

[0036] The most critical aspects of this utility model are as follows:

[0037] 1) Liquid can be evenly distributed on the plane only when the surface is horizontal. The adjustable foot pad 4 of the utility model adjusts the flatness of the platform 2, and the level of the rubber plate is well ensured by measuring with a level meter.

[0038] 2) The thickness of the film. After solving the problem of uniformity of gel on the film, the thickness of each film must be consistent to make the results of each test consistent. Inconsistent gel thickness will affect the test results of each test. The batch difference of the test will be poor. The utility model can make each film have the same thickness under a constant groove depth and in combination with a scraper.

[0039] The method of using the utility model is as follows:

[0040] 1) Select the platform surface according to the thickness of the film to be made (the front and back of the platform 2 can make 4 plastic sheets at the same time, one side makes a 0.6mm thick plastic sheet, and the other side makes a 0.7mm thick plastic sheet);

[0041] 2) Use the four rubber adjustment pads to rotate the platform 2 forward and reverse to adjust it to a horizontal position;

[0042] 3) Place the rubber sheet 1 in the prefabricated groove of the platform 2;

[0043] 4) The negative pressure holes at the four corners (used to connect to the negative pressure connector 3) are used to fix and level the rubber sheet with negative pressure;

[0044] 5) Take 4ml-5ml of the prepared glue and drop it on the rubber plate 1, and scrape it flat with a scraper;

[0045] 6) Allow the glue to cool and solidify;

[0046] 7) Turn off the negative pressure and remove the film to complete the production.

[0047] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
