Abstract

The utility model relates to a cutter for adhesive tapes. A link mechanism and a reset mechanism are additionally arranged between a cutting knife and a trigger; the position of a pinch roller is changed. Thus the adhesive tapes can fast and simply be pressed and contacted to a working substance through the pinch roller. The complete set of operations of rolling, cutting off the adhesive tapes, resetting, etc., can be realized by the trigger. Thus the operation is simple and clean; the adhesive tapes can fully used; the sticking quality can be increased.

Description

Cutter for adhesive tape

The utility model relates to a kind of improvement of adhesive tape cutter.

Public adhesive tape cutter, saw blade is placed the pinch roller top, elder generation is through just being subjected to the saw cut of saw blade behind the tape elongation behind the pinch roller, the adhesive tape that is positioned at the sawtooth top can't be subjected to the roll extrusion of pinch roller again after cutting, must this part be applied to flatten with hand during use and be affixed on the working substance, lose the meaning that pinch roller is set, also pretty troublesome in the operation, expend time in and sticking effect bad.

The purpose of this utility model is the position that is provided with that changes pinch roller, and finger contacts adhesive tape less when increasing connecting rod mechanical connection cutter and making operation, and can the adhesive tape after the cutting is smooth bonding through the pinch roller roll extrusion, simple to operate, quick with the working substance that is stuck.

Utility model is finished like this: a kind of adhesive tape cutter, comprise shell 10, guide wheel 101, pinch roller 102, adhesive tape 20, cutter 122, at cutter 122, set up a linkage and resetting-mechanism between the plate machine 16, this linkage is by driving lever 15, pull bar 14, connecting rod 120, rotating shaft 12, cutting tool post 121 is formed, driving lever 15 wherein, pull bar 14, the connection of connecting rod 120 is hinged, cutting tool post 121 1 ends and rotating shaft 12 bolts, hold and cutter 122 bolts in addition, cutter 122 are arranged between guide wheel 101 and the pinch roller 102, pinch roller is located at from the adhesive tape distance than guide wheel 101 and cutter 122 distant places, resetting-mechanism is the spring 131 that is fixed on the pull bar 14 epirelief tips 141, this spring 131 is the protruding tip 13 of end connection shell 10 in addition, driving lever 15 1 ends 150 are hinged with shell 10, and other holds 151 tops protrusion to be connected with end 141 pin-and-holes of pull bar 14.Plate machine 16 is one to be hinged on the pyriform structure of the narrow bottom width in top at fulcrum 161 places.Rotating shaft 12 is hinged by two ends and shell 10, stage casing connective pole 120 and cutting tool post 121.

Fig. 1: the utility model structural representation.

Fig. 2: the utility model C-C section working state figure ┄ cutter dicing tape position.

Fig. 3: the utility model C-C generalized section ┄ cutter do not have dicing tape.

Now further narrate the utility model in conjunction with the accompanying drawings:

Referring to Fig. 1: adhesive tape cutter shell 10 front ends are provided with the circular adhesive tape chamber 11 of placing adhesive tape, establish central shaft 111 uses for the adhesive tape location at center, circular adhesive tape chamber, the garden cylindrical shell that this central shaft 111 surrounds for several pieces arcs, adhesive tape chamber 11 front ends are provided with guiding channel 112, it is the outlet of pulling out use for adhesive tape, at these guiding channel 112 the place ahead upsides a rotary guide wheel 101 is set, so that the guiding adhesive tape is pulled out, and a rotary pinch roller 102 is set in the upper end of guide wheel 101, so that roll extrusion can smoothly be applied on the working substance adhesive tape after cutting.Appropriate location horizontally set cutter 122 between guide wheel 101, pinch roller 102, these cutter 122 are connected with a linkage by cutting tool post 121.Linkage comprises: be connected the driving lever 15 on shell 10 handles, it can be the center swing by hinged point 150, the middle leading portion front end of driving lever 15 is provided with the plate machine 16 that can do spinning movement, and the point of rotation of plate machine 16 is 161, and the top of driving lever 15 is protruded and is connected with end 141 pin-and-holes of pull bar 14; The front end of pull bar 14 is connected with rotating shaft 12, and the two ends of the two ends of this rotating shaft 12 and shell 10 are hinged; Cutting handle of a knife 121 and cutter 122 bolts.

Back-moving spring 131 front ends are fixed on the protruding tip 13 of shell 10, and in addition end is connected with the protruding tip 141 on the pull bar 14.

Referring to Fig. 2～3: earlier adhesive tape 20 is placed on the central shaft 111 of adhesive tape chamber 11 during use, pull out adhesive tape through guiding channel 112 from the adhesive tape tail end, guide wheel 101, cutter 122, pinch roller 102 positions, when using adhesive tape as long as mat pinch roller 102 overlays the adhesive tape tail end on working substance and takes advantage of a situation and pull out adhesive tape 20, when drawing adhesive tape, pinch roller 102 rolls and overlays the action that adhesive tape 20 is adjacent to itself and working substance simultaneously, cutter 122 contact with adhesive tape 20 at this moment, still keep spacing slightly, as when desiring dicing tape 20, pulling trigger 16, then plate machine 16 meet the middle field offset of hinged point 161 to driving lever 15, promoting driving lever 15 is the center back swing with hinged point 150, the protruding end 151 on mat driving lever 15 tops be pulled pull bar 14 to backward shift this moment pull bar 14 front end be pulled connecting rod 120 simultaneously backward, make rotating shaft 12 simultaneously, tool post 121 is shifted synchronously together with cutter 122, thereby make the position of cutter 122 1 ends close to adhesive tape, beginning dicing tape and local fracture it, the part of not cut is tear fracture easily when adhesive tape leaves shell then.Behind the pressure of pine oil plate machine 16, pull bar 14 is because the effect of back-moving spring 131, makes linkage return to the position that cutter and adhesive tape are a little distance.

The adhesive tape of cutter 122 cuttings still via pinch roller 102 roll extrusion, makes it closely connected in working substance, does not need to smooth adhesive tape with hand.
