The sealing and cutting knife has the advantages of being simple in structure, easy to be assembled, low in cost and good in sealing and cutting effect.
Description
Technical field
The utility model relates to a kind of heat shrinkage film wrapping machine sealing-cutting device, especially relates to a kind of heat shrinkage film yardage roll wrapping machine sealing cutter.
Background technology
Chinese invention patent 201210014583.4 discloses a kind of combination sealing cutter device for wrapping machine, comprise a tool rest, two envelope cuttves and a cutting knife, heat-generating pipe is installed on the tool rest, the lower end of tool rest is equipped with two envelope cuttves, between two envelope cuttves cutting knife is installed, and there are the following problems for the sealing cutter of this structure: at first, assembly difficulty is bigger, when two envelope cuttves are assembled, be difficult to guarantee that the end face of two envelope cuttves is in same plane, thereby the effect of sealing is exerted an influence; Secondly, for guaranteeing that cutting knife is assemblied between two envelope cuttves smoothly, envelope cutter and the contacted end face of cutting knife need arrange the radian of an indent, so after cutting knife is packed into, the gap that can produce an indent between cutting knife and the envelope cutter, the film silk that produces in the working process is embedded in this indent gap, when cutting off easily next time, the film silk that is embedded in wherein can be bonded at the cut-out sealing part, thereby influences seal clean and tidy and attractive in appearance; The 3rd, the sealing cutter of this sectional construction, the temperature of heat-generating pipe is difficult to detect on its tool rest, simultaneously owing to the selected material of tool rest, envelope cutter and cutting knife is different, often be difficult to detect and seal Qie Wendu accurately, and the cut-out temperature requirement of plastic sheeting is strict, if temperature is difficult to control, then can has a strong impact on envelope and cut effect; The 4th, the sealing cutter of this sectional construction need be opened 3 kinds of moulds at least, and cost is higher.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, be easy to assemble, with low cost and envelope cuts effective heat shrinkage film yardage roll wrapping machine sealing cutter.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of heat shrinkage film yardage roll wrapping machine sealing cutter, comprise pedestal, the lower surface of described pedestal is the face of sealing, the described face of sealing is a plane, described sealing has been wholely set a convex tendon on the face, described convex tendon is described to be divided into the identical two parts of width with the equal in length of the face of sealing and with the described face of sealing, described pedestal is provided with heat-generating pipe mounting hole and thermocouple mounting hole, the vertical distance to described convex tendon top equates to the center of the vertical distance on described convex tendon top and described thermocouple mounting hole for the line of centres of the center of described heat-generating pipe mounting hole and described thermocouple mounting hole and the central axes of described convex tendon, the center of described heat-generating pipe mounting hole.
The top of described convex tendon is 0.2mm---3mm to described vertical distance range of sealing face.
The width of described convex tendon top end face is less than the width of lower surface, and the width of described convex tendon top end face is less than 0.1mm.
Two side end faces and described the sealing of described convex tendon are provided with the arc transition face between the face.
The described width range that seals face is 1mm---10mm.
Described face and the described convex tendon surface plating teflon of sealing.
The material of described pedestal and described convex tendon is aluminum alloy.
The upper end of described pedestal is installation portion, and the axial cross section of described installation portion is " ten " font.
Compared with prior art, advantage of the present utility model is:
(1) this sealing cutter integrally casting moulding has at first solved the big problem of sectional construction assembly difficulty in the past, and next has guaranteed that the face that seals on both sides keeps at grade, thereby seal quality is guaranteed, and the 3rd, saved the die sinking cost;
(2) the top vertical distance to convex tendon equates to the center of the vertical distance on convex tendon top and thermocouple mounting hole at the center of heat-generating pipe mounting hole, thermocouple is recorded cut off temperature comparatively accurately, thus assurance cut-out quality;
(3) two of convex tendon side end faces and seal and be provided with the arc transition face between the face prevent that the film silk that produces in the work is attached to tool surface, thereby guarantee to cut each time the clean and tidy and aesthetics of sealing;
(4) the whole aluminum alloy materials that adopts of the sealing cutter of integrally casting moulding has reduced cost, makes that simultaneously the temperature accuracy that records is higher.
