Problems solved by technology
The traditional method of inserting the rubber strip into the profile and cutting it is: first guide the rubber strip into the rubber strip groove of the profile by hand, and then use scissors to cut off the rubber strip against the inclined end face of the profile. Two shearing actions with different angles are required, which is not only inefficient, but also easy to cause operator fatigue and labor-intensive, and human hands may be injured by touching the sharp corners of the profile end face, which poses a certain safety hazard

Embodiment Construction
[0025] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.
[0026] According to the angle of the two end faces of the profile, the cutting knife device of the present invention can cut the rubber strips with the same end face angle, such as Figure 9 As shown, the angle between the front end surface 71 of the profile 7 and its longitudinal direction is A1, and the angle between the rear end surface 72 and its longitudinal direction is A2. Of course, the angle of the two end faces of the profile 7 mentioned here refers to the angle of the end face of the profile at the position where the rubber strip is installed. The ends are flush.
[0027] Such as figure 1 As shown, the cutting knife device with embedded rubber strips in the profile of the present invention mainly includes: an upper knife 1, a lower knife 2 and a guide device. Wherein, the upper knife 1 and the lower knife 2 face up and down and realiz...

The invention discloses a cutter device for profile embedded adhesive tapes. The cutter device comprises an upper cutter (1) and a lower cutter (2); the upper cutter (1) comprises a cutter holder (11), and two blades (12) respectively fixed on the front and back sides of the lower part of the cutter holder (11); the angle of the blade (12) on the front side is the same with the angles of the backend surfaces of profiles; the angle of the blade (12) on the back side is the same with the angles of the front end surfaces of the profiles; the lower cutter (2) comprises a cutter base (21); the cutter base (21) is provided with a gap (22) rightly below the upper cutter (1); and sharp angle lines, cooperating with the blades (12) on the front and back sides for realizing a shearing function, areformed in the intersections between the front and back wall surfaces of the gap (22) and the top surface of the cutter base (21). The cutter device for the profile embedded adhesive tapes can once realize twice shearing actions of the front and back ends of the adhesive tapes, greatly saves the labor force, and is more convenient and safer to operate.
Description
technical field [0001] The invention relates to a cutting device, in particular to a cutting knife device for cutting a profile embedded rubber strip. Background technique [0002] In the prior art, some profiles need to be embedded with rubber strips to achieve waterproof and sound insulation effects, such as: aluminum strips used for door and window frames, such as Figure 9 As shown, the aluminum strip 7 is provided with a strip installation groove 73 for the strip to penetrate along its length direction. The two ends of these aluminum strips 7 are usually designed as inclined planes to facilitate the splicing of the aluminum strips in both horizontal and vertical directions. The inclined planes of the end faces are often not parallel, but have an included angle of 90 degrees. Correspondingly, the cutouts at both ends of the rubber strip embedded in the aluminum strip should be respectively flush with the two ends of the aluminum strip, that is, the two end surfaces of th...
