Description

Immunoblotting film cutting knife

Technical field

The utility model relates to prepare the equipment of in vitro diagnostic reagent more particularly to a kind of immunoblotting film item to cut Knife.

Background technique

Currently, immunology detection technology and products thereof be widely used to great communicable disease, autoimmune disease, Numerous detection fields such as tumor markers, food safety and prenatal and postnatal care, in enzyme-linked immunospot assay test, film item is cut It is an essential process.The cutting knife of film item production is fitted closely by quiet knife and moving knife at present, and when work passes through Shearing is realized in the rotation of moving knife.It is needed in film preparation process using adhesive, adhesive can be adhered on blade in shear history, With the increase of adherency gluing dosage, will lead to blade can not shear completely, cause sheared edge coarse, so that cutting process waste product Rate is excessively high.In order to clear up the adhesive adhered on blade, just needs to clear up blade after cutting 100 every time, frequently clear up blade Necessarily reduce production efficiency, in addition, excessive adherency adhesive also can accelerated wear test blade, make increased costs, it is therefore desirable to change Into.

Utility model content

The main purpose of the utility model is to overcome disadvantages mentioned above existing for existing product, and provide a kind of immunoblotting Film cutting knife reduces the contact surface of film item and moving knife by the rational design for the cutting face structure that quiet knife is contacted with moving knife Product, to effectively reduce moving knife knife face kiss-coating, increase cuts convenience, reduces the rejection rate during film item is cut, reduces knife Pad wear rate improves production efficiency.

The purpose of this utility model is realized by the following technical solutions.

The utility model immunoblotting film cutting knife, including quiet knife and moving knife；The quiet knife is fixed on station side, moves Knife cutting face and quiet knife cutting face fit together, and moving knife is together with quiet knife one end is by bolted splice, and moving knife is to fix spiral shell Bolt is axis rotation, and the shearing force realization generated by moving knife along the rotation of quiet knife cutting face is cut；It is characterized in that, the quiet knife A groove is equipped with the cutting face that moving knife contacts with each other.

Immunoblotting film cutting knife above-mentioned, wherein the quiet knife and moving knife forge integrated molding respectively, which cuts A groove is milled out on bevel, the length of the groove is 170 ± 10mm, and the depth of groove is 1 ± 0.5mm, and the width of groove is 30±5mm。

The beneficial effect of the utility model immunoblotting film cutting knife, it is reasonable in design, it can achieve and cut 1000 Blade is cleared up after the above film item of item, rejection rate reduces during cutting, and cutting efficiency can be improved 20% or so.

Specific embodiment

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model immunoblotting film cutting knife, including quiet knife 5 and moving knife 6；This is quiet Knife 5 is fixed on 7 side of station, and 6 cutting face of moving knife and 5 cutting face of quiet knife fit together, and moving knife and quiet knife one end pass through spiral shell Bolt 1 is hinged, and moving knife 6 is rotated by axis of fixing bolt, the shearing generated by moving knife 6 along the rotation of quiet 5 cutting face of knife Power realization is cut；It is improved in that the quiet knife 5 is equipped with a groove 51 with the cutting face that moving knife 6 contacts with each other.It should Quiet knife 5 forges integrated molding with moving knife 6 respectively, mills out a groove 51 on quiet 5 cutting face of knife, the length of the groove 51 is 170 ± 10mm, the depth of groove 51 are 1 ± 0.5mm, and the width of groove 51 is 30 ± 5mm.

Embodiment 1:

Prepare film cutting knife.

Film cutting knife preparation process, comprising:

1, steel paper cutter is bought, then quiet knife is disassembled, quiet knife is processed into groove in cutting face with milling machine.

2, wherein quiet knife having a size of 210*35*4mm, groove size 170*30*1mm.

3, the quiet knife for processing groove is reinstalled on paper cutter.

Embodiment 2:

Six antinuclear antibodies spectrum diagnosis detection film items are prepared, detection antigen is nRNP, sm, SSA, SSB, Jo-1 and Scl- 70, product structure is as shown in Figure 4.

(1) nRNP (21), sm (22), SSA (23), SSB (24), Jo-1 (25), Scl- first are coated with a stroke film instrument preparation The nitrocellulose filter of 70 (26) antigens, this nitrocellulose filter is pasted on backing.

(2) cut out with the utility model immunoblotting film cutting knife be adhesive with the nitrocellulose filter of antigen backing, Antigenic membrane block, quality control band and the home block cut out are removed protective film by quality control band 27 and home block 4, glutinous according to status requirement It is attached on bottom liner 3, pastes into long slab film item, as shown in Figure 3；

(3) the long slab film item pasted is cut into detection film item with the utility model immunoblotting film cutting knife again, As shown in Figure 4, Figure 5.

If detection film item is to paste dry film block and home block composition on a bottom liner, film block is to contain detection antigenic component Film stripping and slicing, for detecting；Home block is that the stripping and slicing of common paper membrane is printed on title and number, is used for positioned at one end of film item Different film items are distinguished, these are the prior art.

Not by the content being illustrated it is the prior art in the present embodiment, therefore is no longer repeated.
