In order to achieve the above object, of the present utility model a kind of heat-sealing machine heat seal device proposed, comprise the heat seal cutter head, described heat seal cutter head is provided with heater and temperature controller, and described heater is by the connecting axle of thermal insulation board connection cylinder, and described heat-fastening knife cephalic par is provided with the rotary part of being made by exotic material, when film passes through, described rotary part bottom side contacts setting with film, rotary part rotates under the effect of film by power being subject to, and its direction of rotation is identical by direction with film.
Preferential as technique scheme, also comprise riser, described riser is provided with can be with respect to the rotating shaft of described riser rotary setting, it is female to be socketed with the mobile adjustment that arranges on the described rotating shaft, described adjustment mother is provided with little optical axis, described little optical axis upper end is provided with fixed head, and described cylinder is arranged on the fixed head, and described fixed head can be with respect to adjusting female its high and low position of adjusting.
Preferential as technique scheme, described riser is provided with horizontally disposed chute, and described rotating shaft end is arranged in the chute, and fixes by handwheel.
Preferential as technique scheme is provided with stage clip between described heat-fastening knife and the thermal insulation board.
Preferential as technique scheme, described rotating shaft one side is provided with the upset handle.
Preferred as technique scheme, described rotary part is bearing or ceramic ring.
The utility model proposes a kind of heat-sealing machine heat seal device, larger to the film scratching for existing heat seal cutter head, affect the film thermal film problem attractive in appearance of being honored as a queen, the heat-sealing machine heat seal device that the utility model proposes, the heat-fastening knife cephalic par is arranged exotic material make bearing, described bearing rotary direction is identical with the direction that film passes through, when film passes through, described bearing bottom side curved surface contacts setting with film, in the time of can guaranteeing like this film by the heat seal cutter head, the heat-fastening knife cephalic par is reduced drag of film, thereby avoided the scratching to film, seal effectively, and increase heat seal cutter head service life.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, described and other purposes of the present utility model, feature and advantage will be apparent.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of heat-sealing machine heat seal device that the utility model proposes, such as Fig. 1, Fig. 2, shown in Figure 3, comprise heat seal cutter head 1, described heat seal cutter head 1 is provided with heater 2 and temperature controller 3, and described heater 2 is by the connecting axle 8 of thermal insulation board 5 connection cylinders 7, and described heat seal cutter head 1 end is provided with by exotic material makes bearing 17, when film passes through, described bearing 17 bottom side curved surfaces contact setting with film, bearing rotates under the effect of film by power being subject to, and its direction of rotation is identical by direction with film.Bearing bearing pin 19 is installed in bearing 17 on the heat-fastening knife 1, limits bearing 17 positions by stop collar 18, and clamp 16 limits bearing bearing pin 19 and prevents from.Certainly, bearing also can replace with ceramic ring etc.
As shown in Figure 1 and Figure 2, also comprise riser 15, described riser 15 is provided with horizontally disposed chute, described rotating shaft 21 ends are arranged in the chute, and fixing by handwheel 9, upset handle 10 is installed on the rotating shaft 21, adjusts mother 13, unclamp hold-down screw 6, adjusting female 13 can move along rotating shaft 21, adjusts the position of heat seal.Adjust little optical axis 14 is installed on female 13, little optical axis 14 tops are provided with air cylinder fixed plate 12, and cylinder 7 is installed on the fixed head 12, and rotation plum blossom handle 11 can make air cylinder fixed plate 12 band dynamic air cylinders 7 move up and down along adjusting screw rod 20.Cylinder 7 moves up and down by cylinder connecting axle 8 drive thermal insulation boards 5, heat-fastening knife 1.5 of heat-fastening knife 1 and thermal insulation boards are equipped with heat-fastening knife stage clip 4, the impulsive force of 1 hand of available buffer heat-fastening knife.Having heaters 2, temperature controller 3 on the heat-fastening knife 1 are to be heated to design temperature to heat seal cutter head 1.Unclamp the fixedly handwheel 9 of rotating shaft 21, rotate upset handle 10, can make whole heat-fastening knife device rotation, the bottom of being convenient to clear up, repair heat seal cutter head 1.
Certainly; the utility model also can have other embodiment; in the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of claim of the present utility model.
