Problems solved by technology

[0002] Chinese invention patent 201210014583.4 discloses a combined sealing and cutting knife device for packaging machines, including a knife seat, two sealing knives and a cutting knife, a heating tube is installed on the knife seat, and two pieces are installed at the lower end of the knife seat Sealing knife, a cutter is installed between the two sealing knives. The sealing and cutting knife with this structure has the following problems: First, the assembly is difficult. When assembling the two sealing knives, it is difficult to ensure that the end faces of the two sealing knives are in the The same plane, which affects the sealing effect; secondly, in order to ensure that the cutter is smoothly assembled between the two sealing knives, the end face of the sealing knife and the cutter should be provided with a concave arc, so when the cutter is installed Finally, there will be a concave gap between the cutting knife and the sealing knife, and the film filaments generated during the working process will be easily embedded in the concave gap. When cutting next time, the embedded film filaments will stick to the cutting seal , thereby affecting the cleanliness and beauty of the seal; thirdly, the temperature of the heat pipe on the knife seat is difficult to detect for the combined structure of the sealing knife, and at the same time, it is often difficult to detect the temperature of the heating pipe on the knife seat due to the different materials selected for the knife seat, sealing knife and cutter. The accurate sealing and cutting temperature is detected, but the cutting temperature of the plastic film is relatively strict. If the temperature is difficult to control, it will seriously affect the sealing and cutting effect; fourth, the sealing and cutting knife of this combined structure needs to open at least 3 kinds of molds, and the cost is high

Embodiment 1

[0020] Embodiment one: if figure 1 As shown, a sealing and cutting knife for heat-shrinkable film cloth roll packaging machine includes a base 1, the lower end surface of the base 1 is a sealing surface 2, the sealing surface 2 is a plane, and a convex surface is integrally arranged on the sealing surface 2. The ribs 3 and the protruding ribs 3 are equal in length to the sealing surface 2 and divide the sealing surface 2 into two parts with the same width; The line connecting the center and the center of the thermocouple mounting hole 5 coincides with the central axis of the rib 3, and the vertical distance H between the center of the heating pipe mounting hole 4 and the top of the rib 3 1 The vertical distance H from the center of the thermocouple installation hole 5 to the center of the heat pipe installation hole 4 2 equal.

[0021] In this specific embodiment, the vertical distance H from the top of the rib 3 to the sealing surface 2 is 0.2 mm.

[0022] In this specific...

Embodiment 2

[0028] Embodiment 2: Other parts are the same as Embodiment 1, the difference is that the vertical distance H from the top of the rib 3 to the sealing surface 2 is 3 mm.

Embodiment 3

[0029] Embodiment 3: Other parts are the same as Embodiment 1 and Embodiment 2, except that the width L of the sealing surface 2 1 10mm.

Abstract

The invention discloses a sealing cutter for a thermal shrinkage film yardage roll packaging machine. The sealing cutter is characterized by comprising a base. The lower end face of the base is a seal face which is a plane. A protruding rib is integrally arranged on the seal face. The protruding rib is equal to the seal face in length and divides the seal face into two parts with the equal width. A heating pipe installation hole and a thermo-electricity coupler installation hole are formed in the base. A connecting line from the center of the heating pipe installation hole to the center of the thermo-electricity coupler installation hole coincides with an axial line of the center of the protruding rib, and the perpendicular distance from the center of the heating pipe installation hole to the top end of the protruding rib is equal to the perpendicular distance from the center of the thermo-electricity coupler installation hole to the top end of the protruding rib. The sealing cutter has the advantages of being simple in structure, easy to assemble, low in cost, and good in sealing-cutting effect.
