Abstract

A kind of screen printing sizing agent perching knife, including handle of a knife, the handle of a knife end are provided with perching knife, and the perching knife is PVDF material perching knives, and the perching knife includes at least two blades, and the blade tip of one of blade is arc, and the blade tip of another blade is perpendicular type.The point of a knife of the trapezoidal perching knife of class is arc point of a knife, and on the one hand the utility model can smoothly scrape the slurry of size barrel arm and bucket bottom, the wherein slurry in the curved region of radian can also scrape in the lump；Another aspect the design perching knife is provided with handguard, and when horizontal positioned perching knife, due to the supporting role of handguard, cutter head side is propped up, and can prevent the slurry contamination on perching knife.

Description

A kind of screen printing sizing agent perching knife

Technical field

A kind of spade blade device is the utility model is related to, more particularly to a kind of screen printing sizing agent spade blade device.

Background technology

At present, the silkscreen process of solar cell, because positive silver electrode paste viscosity is bigger than normal, it is still desirable to manually Add the mode of slurry to carry out, during need to take slurry in size barrel with perching knife shovel, and be transferred in half tone, slurry will in bucket When being finished, slurry in bucket need to be scraped totally, to prevent excessive residual slurry from, to bucket arm, causing with other objects such as scraping article Waste, size barrel arm and bucket bottom are often the curved connection of radian, scrape that the difficulty of slurry is also bigger than normal, and the curved region residual slurry of radian is inclined It is more, waste serious.When perching knife with slurry is placed, one article of pad, cutter head is propped up, prevents the slurry on cutter head below blade Other regions are contacted to pollute.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of slurry perching knife of new structure, on the one hand can be suitable The scraping size barrel arm of profit and the slurry at bucket bottom, the wherein slurry in the curved region of radian can also scrape in the lump；On the other hand originally set Meter perching knife is provided with handguard, and when horizontal positioned perching knife, due to the supporting role of handguard, cutter head side is propped up, and can prevent from shoveling Slurry contamination on knife.

To achieve the above object, the utility model uses following technical scheme：A kind of screen printing sizing agent perching knife, including knife Handle, the handle of a knife end are provided with perching knife, and the perching knife is PVDF material perching knives, and the perching knife includes two blades, wherein one The blade tip of individual blade is arc, and the blade tip of another blade is perpendicular type.

Preferably, the perching knife is provided with backplate with handle of a knife junction, and the backplate is hook backplate.

Compared with prior art, the beneficial effects of the utility model are：The design of handguard is placed with vertical suspension, also may be used With horizontal positioned, when horizontal positioned, handguard can prop up blade, can prevent the slurry contamination on blade；Blade has two knives Point, a point of a knife are right angle point, can scrape the slurry of right angle crook, such as the slurry remained on bung；Another point of a knife is Arc point, the slurry of fillet crook, such as the slurry of bucket bottom can be scraped.

Brief description of the drawings

For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.

Fig. 1 is the utility model structure diagram.

Fig. 2 is the utility model structure diagram 2.

Fig. 3 is schematic diagram when the utility model slurry perching knife scrapes bucket prime cement material.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model Define.

As Figure 1-3, a kind of screen printing sizing agent perching knife, including handle of a knife 1, the end of handle of a knife 1 are provided with perching knife 2, The perching knife 2 is PVDF material perching knives, and the perching knife 2 includes two blades（3、4）, the blade tip of one of blade 3 is arc, The blade tip of another blade 4 is perpendicular type.

Preferably, the perching knife 3 is provided with backplate 5 with the junction of handle of a knife 1, and the backplate is hook backplate.

As shown in figure 3, the utility model arc blade tip can with bucket bottom radian is curved is brought into close contact, more effectively scrape bucket bottom Slurry, residual slurry in bucket is reduced, reduce and waste.

It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to In this, any change or replacement expected without creative work, should all cover within the scope of protection of the utility model； Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
