The width of the cutter groove is 2-4 mm, and the width of the cutter groove is reduced so that the cutter groove can be just matched with the easy-to-tear opening cutter, and therefore the situation that the transverse seal is extruded and damaged and the appearance quality is not qualified due to the fact that the packaging bag is excessively extruded into the cutter groove when the cutter acts is avoided. According to the utility model, the cutting stability of the easy-to-tear wire can be improved, and the production quality of the easy-to-tear wire is further improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of easy-tear line production, and in particular relates to a stability improvement device for an easy-tear line of a back-seal strip packaging machine. Background Art

[0002] In the production process of the single-row back-strip packaging machine, since the existing easy-tear line cutting groove uses a silicone pad as a buffer, the material support is not enough and the service life is short. When the easy-tear line knife is in action, the packaging material will also be squeezed into the knife groove, resulting in an uneven cut surface of the easy-tear edge. After the easy-tear line is cut, the appearance of the product will have marks left by the knife groove extrusion and uneven cut depths of the easy-tear line, resulting in the easy-tear line quality not meeting production requirements, and easily causing the easy-tear line position to be too deeply indented, the cut to be too large, etc. In severe cases, it may affect the sealing of the produced products and cause quality problems such as product leakage.

[0003] In summary, the production quality of the easy-tear wire of the existing equipment is unstable. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a device for improving the stability of the easy-tear line of a back-seal packaging machine. The technical problem to be solved by the utility model is how to improve the stability of the easy-tear line during cutting, thereby improving the production quality of the easy-tear line.

[0005] In order to solve the above technical problems, the utility model provides a device for improving the stability of the easy-tear line of a back-seal bagging machine, comprising a device body;

[0006] The two ends of the device body are symmetrically provided with fixing holes, a knife groove is provided between the two groups of fixing holes, and the device body is made of polytetrafluoroethylene material.

[0007] Furthermore, the cross section of the knife groove is semicircular.

[0008] Furthermore, the width of the slit is 2-4 mm.

[0009] Furthermore, the depth of the knife groove is 2-4 mm.

[0010] Further, the fixing hole includes a first fixing hole and a second fixing hole, and the first fixing hole is arranged above the second fixing hole.

[0011] Furthermore, the first fixing hole is conical.

[0012] Furthermore, the second fixing hole is cylindrical.

[0013] The utility model discloses a device for improving the stability of the tear line of a back-seal packaging machine. The device body is made of polytetrafluoroethylene material. The polytetrafluoroethylene material has stronger support and durability, which can not only extend the service life of the device body, but also provide sufficient support force when the tear line is cut, thereby improving the production quality of the tear line. The width of the knife groove is 2-4mm. The width of the knife groove can be reduced to match the tear cutter, thereby avoiding squeezing too much packaging bag into the knife groove when the cutter is in action, resulting in the horizontal seal being squeezed and damaged and the appearance quality not being up to standard. The utility model can improve the stability of the tear line when it is cut, thereby improving the production quality of the tear line. BRIEF DESCRIPTION OF THE DRAWINGS
