Description

Sealing knife for thermal sealing and cutting machine

The utility model relates to a kind of heat-sealing cutter envelope cutter, especially the lifting assembly that refers to a kind of tool setting of spring mechanism, but its structure of mat makes envelope cutter pressure unanimity, the closely knit plastic bag that compresses, and the anti-jamming rectangular guide hole of design envelope cutter, the support of its cutting knife is then with the cutter bar locking, and cutter bar is " one " word shape for middle recessed one section, and its effect can be kept the steady and certain of envelope cutter mechanism.

Envelope knife structure commonly used, its pattern has multiple, though through deducing and improvement, it is inaccurate to still have envelope to cut, not driving fit during involution is easy to come off, or produces cutting knife and can't cut off the situation of plastic bag, increases to handle and goes up tired scratching.Because the heat-sealing cutter must be added heat-sealing-cutting with electric heating, each parts Yi Yinre passes effect and produces het expansion, therefore the cooperation or the action of member is subject to the influence of thermal expansion metal, produces interference or blocks and can't homing put, even because of not well-thought to this factor, make envelope cutter and cutting knife produce flexure deformation, not only influence the mechanical action effect, and make the work can't be smooth and easy, incur loss through delay timeliness, increase the inconvenience of processing.

Main purpose of the present utility model is to provide a kind of heat-sealing cutter envelope cutter, can be by the adjusting mechanism on the adjustment rack, and the action of the spring in the adjustment nut, make envelope cutter depression bar the level of making kinetic energy adjustment envelope cutter group or with the driving fit situation of pad pressure device, make the start of envelope cutter certain.

Another purpose of the present utility model is to provide a kind of heat-sealing cutter envelope knife structure, and the guide hole of its braking envelope cutter depression bar is made oblong aperture, makes that action is smooth and easy down on the envelope tool rest, reduces thermal expansion influence.

A purpose more of the present utility model is to provide a kind of heat-sealing cutter envelope cutter, and its cutter part is made as the cutter bar stage casing flat-shaped, and can bear the thermal pressure that cutting knife causes, it is straight that cutting knife is kept, and reduces the ill effect of distortion generation.

According to the utility model, a kind of hot-cutting machine envelope cutter, cording has the adjusting mechanism that is linked to the envelope cutter to make the squeezing action of envelope cutter, and the cutter bar stage casing is made flat-shaped, to reduce the influence of cutting knife distortion, it is characterized in that comprising: adjusting screw rod is that its outer rim has screw thread, and interior is the elongated rod shape of circular hollow hole, one end is closed, but is provided with rectangular open-work, leaves and seal the het expansion clearance of cutter depression bar; Heat insulating washer is the thin ring-type of hollow; Hold-doun nut is circular, and interstitial hole has negative thread, and the annulus outer rim is provided with a plurality of shrinkage pools of circumference in equal parts, uses as locking; Pressure spring shape in the shape of a spiral also can be put into adjustment screw rod hollow hole; Adjusting nut is the hollow cylindrical that an end has closing face, and the periphery of its endoporus is provided with screw thread; Envelope cutter depression bar is circular elongated rod shape, and an end has screw thread can be screwed together in the envelope cutter, heat insulating washer in the other end fit; Cutter bar is circular bar shape, and the one end has screw thread and can lock on the adjustment rack, and the other end is provided with a short slot and circular opening inserts locking for cutting knife, and middle again have one section to be recessed into the cross section that becomes " one " word shape, can bear the thermal stress that causes because of cutting knife.

Now conjunction with figs. describes structure, feature, the effect of the utility model as the back in detail for an embodiment:

Fig. 1 is a block diagram of the present utility model.

Fig. 2 is that cutter bar of the present utility model is subjected to thermal stress and the scheme drawing of bending.

Fig. 3 is a cutaway view of the present utility model.

Fig. 4 is an action scheme drawing of the present utility model.

See also Fig. 1, the utility model is by adjustment rack 1, envelope cutter setting device 2, and envelope cutter depression bar 31, envelope knife system 3, cutter bar 4, cutter 5, heat-resisting fabric 6, pad depression bar 7 members are formed; Wherein adjustment rack 1 is the hollow rod shape that is wide " protruding " word shape, and its cross section is the square shape, is provided with the hole, three places of adjusting screw rod 21 between end face and bottom surface, respectively is provided with the lifting bar of cutter bar 4 and support adjustment rack 1 knee-action simultaneously in both sides; Adjusting screw rod 21 is to be outer rim screw thread is arranged, interior is the elongated rod shape of circular hollow hole, the one end then is closed, but be provided with rectangular open-work 211, and and leave between the envelope cutter depression bar 31 and seal the bigger het expansion clearance of cutter het expansion direction, the rectangular open-work end of tool places the below, locks on the adjustment rack 1 and will adjust screw rod 21 with insulating collar 22 and hold-doun nut 23; Insulating collar 22 is the thin shape of hollow, puts hold-doun nut 23 on it again, and for circular, its interstitial hole has negative thread, and the annulus outer rim is provided with a plurality of shrinkage pools of branch circumference, as the usefulness of locking;
