AI Technical Summary
The cutting cavity of the traditional horizontal sealing machine cutter has a right angle, which makes it difficult for the waste edge to slide out and it is easily sucked up and carried away. In addition, the cutter mold is prone to jamming after long-term use, which affects the cutting smoothness and service life.
The internal corner of the cutting cavity was changed to an R-angle, and a cavity clearance groove and a punch clearance groove were designed on the inner and outer molds of the cutting cavity. A side clearance groove was also added to the outside of the cutting punch to optimize the structure of the cutting cavity and reduce the difficulty of jamming and scrap edge slippage.
The increased strength of the cutting die reduces the risk of breakage, makes it easier for waste edges to slide out, reduces die jamming, and improves cutting smoothness and service life.

[0025] AsFigures 1-5 As shown in the figure, a cutting knife of a transverse sealing machine comprises a cutting knife male die 100 and a cutting knife female die 200, the cutting knife male die 100 comprises an outer die 110, an inner die 120, a cutting blade 130 and a mounting hole 140, the cutting knife female die 200 is provided with a fixing hole 210 at the top end, and is provided with a cutting cavity 220 inside, the cutting blade 130 is arranged on the inner die 120, the mounting hole 140 is arranged on the outer die 110, the mounting hole 140 is connected with a transmission mechanism, the cutting knife male die 100 is connected with the cutting knife female die 200 in a plug-in mode through the cutting cavity 220, the outer die 110 is arranged outside the cutting cavity 220, the inner die 120 is arranged inside the cutting cavity 220, the inside corner 221 of the cutting cavity 220 is an R angle, one side of the cutting cavity 220 is provided with a female die avoiding groove 222, the outer die 110 is provided with a male die avoiding groove 111 below, and the cutting knife male die 100 is provided with side avoiding grooves 150 on both sides.
[0026] As shown in the figure, the female die avoiding groove 222 comprises an upper avoiding groove 223 and a lower slope 224, the upper avoiding groove 223 is arranged on both sides above the cutting cavity 220, and the lower slope 224 is arranged below the cutting cavity 220.
[0027] As shown in the figure, Figure 7 and Figure 8 The utility model discloses an innovation point, first, the inside corner 221 of cutting knife female die 200 is changed from a right angle to an R angle on the basis of the traditional structure, and there are totally 8 angles from the figure. The advantage is that the strength of the cutting knife male die 100 can be enhanced, and the risk of fracture at the original right angle is greatly reduced. Then the female die avoiding groove 222 is designed in the cutting cavity 220. The female die avoiding groove 222 is divided into the upper avoiding groove 223 and the lower slope 224, the two sides of the protrusion inside the top position of the cutting cavity 220 are hollowed out, the symmetrical expected space is set to the upper avoiding groove 223. The protrusion that is symmetrical up and down at the bottom inside of the cutting cavity 220 is cut off, and a lower slope 224 structure is formed. The most intuitive structure design is that the length of the cutting cavity 220 is shortened.
[0028] As shown in the figure, Figure 6As shown, on the other hand, we set the convex mold avoidance slot 111 below the outer mold 110 of the cutter convex mold 100, which is to form the convex mold avoidance slot 111 by hollowing out a set of symmetric reserved spaces below the outer mold 110. Then when the cutter convex mold 100 and the cutter concave mold 200 are combined, when the cutter convex mold 100 cuts in, the convex mold avoidance slot 111 can avoid the strip bag width direction cooperation, and the generated round corner scrap edge can better slide out from the upper layer avoidance slot 223 and fall off, avoiding being taken out by the cutter convex mold 100 from the entrance of the cutter concave mold 200, and realizing better waste falling. The front end part expects a larger space, and the formed avoidance slot also causes the length of the cutting cavity 220 to be shortened, directly avoiding the scrap edge from being stuck in the gap. As shown, Figure 9 As shown, through the above-mentioned interlocking design, the problem of the scrap edge 1 being stuck in the slot is solved.
[0029] Finally, we also design a side avoidance slot 150 on the outside of the cutter convex mold 100, which is formed by cutting off the outside part connected with the cutter concave mold 200. The essence is to reduce the contact area of the cutter convex mold 100 and the cutter concave mold 200 to avoid their long-time force jamming.
[0030] Compared with the prior art, the utility model discloses the inside corner of cutting cavity is changed from right angle to R angle, the strength of the concave mold is enhanced, the risk of breaking is reduced, the concave mold avoidance slot and the convex mold avoidance slot are increased, the round corner scrap edge is more easily slid out and falls off, the side avoidance slot is increased, and the force jamming of the cutter convex mold and the cutter concave mold is reduced.
[0031] The specific embodiments of the utility model are described above, but the utility model is not limited to this, as long as the purpose of the utility model is not deviated, the utility model can also have various changes.
