Detailed Description

Referring to fig. 1-3, the scraper for the SMT printer comprises a base 1, wherein a mounting groove 2 is formed in the base 1, a scraper blade 3 made of rubber materials is arranged in the mounting groove 2, a locking component 4 for folding the mounting groove is arranged on the mounting groove 2, and a limiting component 5 is arranged in the mounting groove 2; a clamping lug 6 is arranged on the near end part of the opening end of one side of the mounting groove 2, and when the inner wall of the mounting groove is clung to the doctor blade, the clamping lug presses the doctor blade. To increase the compression effect, a plurality of clamping projections may be provided at intervals.

The base is made of elastic metal material, such as aluminum alloy, the width of the mounting groove is equal to the thickness of the doctor blade, and in an initial state, the opening of the mounting groove is outwards opened, and the width of the opening is slightly larger than the thickness of the doctor blade.

The width and angle of the mounting groove can be set according to the angle required in specific use, and the angle of the common scraper mainly comprises 0 degree, 60 degrees and 45 degrees.

The mounting groove 2 is folded through the locking component 4 to clamp the doctor blade 3, and the locking component 4 stops folding when the limiting component 5 is contacted with the inner side surface of the mounting groove 2. In this embodiment, the doctor blade is made of a rubber material, and when the mounting groove is folded to clamp the doctor blade, the doctor blade can be folded continuously, which easily causes the deformation of the side wall of the mounting groove to be too large, and the elasticity is lost, so that the doctor blade cannot be recovered. The locking component is limited through the limiting component, so that the mounting groove is prevented from being excessively folded.

Of course, the doctor blade may also be a steel sheet, in which case the corresponding strip is fitted in the mounting groove, which is an equivalent alternative that will readily occur to those skilled in the art.

In this embodiment, a positioning block 7 integrally formed with the base 1 is disposed at the bottom of the mounting groove 2, and a clamping groove 8 communicated with the mounting groove 2 is disposed on the positioning block 7; the locking component 4 is arranged on the side wall of the clamping groove 8, and the limiting component 5 is arranged in the clamping groove 8. The positioning block is arranged to facilitate positioning and mounting of the scraper blade, and meanwhile, the clamping groove is formed in the positioning block, the locking assembly and the limiting assembly are both arranged in the clamping groove, so that the possibility that the scraper blade is interfered with the locking assembly and the limiting assembly is reduced, and the scraper blade is convenient to mount.

In this embodiment, preferably, one end of the positioning block 7 contacts with the side wall of the mounting groove 2, and a clamping groove 8 is formed between the positioning block 7 and the other side wall of the mounting groove 2. The clamping groove is arranged on one side of the clamping groove, so that the thickness of the side wall is reduced, the force required by extruding the side wall of the clamping groove can be reduced, and the clamping is convenient.

Further preferably, a relief notch 9 is provided in the bottom of the clamping groove 8 to facilitate clamping of the side wall of the mounting groove 2. After the yielding notch is arranged, the bottom of the side wall of the clamping groove is convenient to rotate, so that the force required by extruding the side wall of the clamping groove can be reduced, and the clamping is convenient.

In this embodiment, the locking assembly 4 includes a nut 4a disposed on one side wall of the mounting groove 2, a countersunk screw hole 4b opposite to the nut 4a is disposed on the other side wall, and a clamping screw 4c penetrating through the countersunk screw hole 4b and being in threaded connection with the nut 4a is disposed on the outer wall of the mounting groove 2. In addition, the locking assembly may take other forms as would be readily apparent to one skilled in the art, such as providing adjustable clamps at the ends of the base.

In this embodiment, the limiting assembly 5 includes a plurality of shims 10 disposed in the mounting groove 2; when the side wall of the mounting groove 2 clamps the doctor blade 3, both sides of the spacer 10 are in contact with the side wall of the mounting groove 2. The gasket is made of harder materials, and when the side walls of the mounting groove are clung to the gasket, the two side walls of the mounting groove are parallel and have the same width with the doctor blade. In this embodiment, the gasket is disposed in the clamping groove, and the gasket is provided with a mounting hole adapted to the clamping screw, and is mounted on the clamping screw by being sleeved.

In addition, the spacing assembly may take other configurations that will be readily apparent to those skilled in the art, such as providing a stiffer support directly on the doctor blade.

When the scraper blade is used, the scraper blade is placed in the mounting groove, the clamping screw is screwed until the inner wall of the clamping groove is tightly attached to the gasket, and the clamping and mounting of the scraper blade are completed.

The above examples are provided for convenience of description of the present utility model and are not to be construed as limiting the utility model in any way, and any person skilled in the art will make partial changes or modifications to the utility model by using the disclosed technical content without departing from the technical features of the utility model.
