The utility model discloses a following technical scheme realizes above-mentioned purpose:

a cutter holder for a sealing device of a food packaging machine comprises an upper cutter holder and a lower cutter holder, wherein a sealing cutter is further arranged in the upper cutter holder, the upper cutter holder and the lower cutter holder are both cubic, and the lower end parts of the short side edges of the upper cutter holder and the lower cutter holder are fixedly provided with a fixed seat; the fixed seat is provided with at least one through hole; a plurality of teeth are arranged on the opposite surfaces of the upper tool apron and the lower tool apron, the teeth of the upper tool apron and the teeth of the lower tool apron are distributed in a staggered manner, a first groove is further formed in the position along the connecting line of the midpoints of the short sides of the upper tool apron, and a second groove is further formed in the position along the connecting line of the midpoints of the long sides of the upper tool apron and the lower tool apron; the stress at the sealing opening of the back seal can be effectively reduced through the second groove, and the breakage rate is reduced.

As a further optimization scheme of the utility model, the interval of tooth is 1.8 to 2.2mm, and the height of tooth is 1.4 to 1.6 mm.

As a further optimization scheme of the utility model, the degree of depth of second recess is established to 0.5 mm.

As a further optimization scheme of the utility model, it is equipped with two breachs still to symmetry on the bottom of lower blade holder.

The beneficial effects of the utility model reside in that:

1) in the utility model, the groove is arranged at the position of the back seal sealing position at the top of the cutter holder, so that the breakage rate near the back seal sealing position can be effectively reduced;

2) the cutter holder is integrally divided into two split bodies through the first groove, so that two bag openings can be sealed through one-time sealing, and the sealing efficiency of the back sealing bag is greatly improved;

3) through the sword that seals that sets up in the last blade holder, can seal in, cut the bag promptly and handle, effectively promote machining efficiency.

in the figure: 1. an upper tool apron; 11. a sealing knife; 2. a lower tool apron; 3. a fixed seat; 31. a through hole; 4. Teeth; 5. a first groove; 6. second recess, 7, breach.

Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

As shown in fig. 1 to 3, the knife holder for the sealing device of the food packaging machine comprises an upper knife holder 1 and a lower knife holder 2, wherein a sealing knife 11 is further arranged in the upper knife holder 1, the upper knife holder 1 and the lower knife holder 2 are both cubic, and a fixing seat 3 is further fixedly arranged at the lower end of the short side of each of the upper knife holder 1 and the lower knife holder 2; the fixed seat 3 is provided with two through holes 31; a plurality of teeth 4 are arranged on the opposite surfaces of the upper tool apron 1 and the lower tool apron 2, the teeth 4 of the upper tool apron 1 and the teeth 4 of the lower tool apron 2 are distributed in a staggered manner, a first groove 5 is also arranged along the connecting line of the midpoints of the short sides of the first groove, and a second groove 6 is also arranged along the connecting line of the midpoints of the long sides of the first groove; the distance between the teeth 4 is 1.8-2.2 mm, and the height of the teeth 4 is 1.4-1.6 mm; the depth of the second groove 6 is set to be 0.5 mm; two notches 7 are symmetrically arranged at the bottom of the lower tool apron 2.

The utility model discloses a working method and principle:

generally, the back sealing process of the flexible package generally comprises the processes of unreeling, folding, longitudinal sealing, transverse sealing and bag cutting; a semi-finished film roll produced by printing, compounding, slitting and other processes is arranged on a feeding scroll of a bag making machine; then, the film is folded into a specified product size by using a shaping plate and a folding device; heat-sealing the back seal of the bag by using a longitudinal seal sealing knife; then, the top seal of the bag is heat sealed by using a transverse sealing knife; tracking the bag making mark by using a photoelectric eye, and then cutting a finished product by using a cutter;

however, in the packaging process and the longitudinal sealing process, because the thickness of the back seal of the back package is greater than the thickness of other parts, the use of a common cutter holder can often cause the damage near the back seal, the sealing efficiency is not good, and the transverse sealing process and the bag cutting process are separated in the common process, so the working efficiency is not high;

therefore, in the utility model, when the longitudinally sealed bag is moved to the transverse sealing position, the upper knife holder 1 of the utility model is moved downwards, the teeth on the upper knife holder 1 and the lower knife holder 2 are matched with each other to seal the opening of the back sealing bag, and the sealing knife in the upper knife holder is used for cutting the bag in time when the bag is sealed; in addition, a heating device is generally provided on the upper and lower tool holders 2.

The structure of utilizing this blade holder like this not only can reduce the breakage rate of back envelope bag, can also improve the machining efficiency of technology simultaneously.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
