Problems solved by technology

[0008] The selection of the cutting area can only be limited to several positions where the ring groove is located, the cutting selectivity is poor, and the linear selection of the cutting area cannot be realized
Since the fixed rod is fixed, the choice of cutting angle can only be realized by turning the blade, and the cutting flexibility is poor

Embodiment Construction

[0024] The thread cutting mechanism of the bag making machine of the prior art is as figure 1 As shown, it includes a fixed shaft 1, a thread cutting device, and a fixed rod 3. The fixed shaft 1 is placed horizontally on the frame, and its axial direction is perpendicular to the conveying direction of the packaging bag. The fixed rod 3 is arranged side by side with the fixed shaft 1 . A plurality of ring-shaped grooves 5 are spaced apart on the fixed rod 3 . The thread cutting device includes a handle 21 and a blade 22 . One end of the knife handle 21 is sheathed on the fixed shaft 1 , and the other end of the knife handle 21 is connected with the blade 22 .

[0025] Such as Figure 2-3 As shown, the embodiment of the present invention discloses a thread cutting mechanism of a bag making machine, including a fixed shaft 1 and a thread cutting device. The fixed shaft 1 is placed horizontally on the frame (not shown in the figure), and its axial direction is perpendicular to...

Abstract

The invention discloses a line cutting mechanism for a bag-making machine. The mechanism comprises a fixing shaft and a line cutting device, wherein the fixing shaft is transversely arranged on a rack, and the axial direction of the fixing shaft is vertical to the conveying direction of a packaging bag; the line cutting device is arranged on the fixing shaft in a sliding fit manner and can axially move along the fixing shaft; the line cutting device comprises a first connecting block, a hinge pin, a second connecting block, blades and an L-shaped cutter seat; the L-shaped cutter seat comprises a base and a third connecting plate; a strip-shaped groove is formed in the base; the length direction of the strip-shaped groove is parallel to the conveying direction of the packaging bag and the strip-shaped groove passes through the base. The mechanism has the advantages of being simple to operate, simple in structure, and high in cutting flexibility, and achieving the linear selection of a cutting area.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a thread cutting mechanism of a bag making machine. Background technique [0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. Widely used in daily life and industrial production. [0003] Packaging bags include woven bags and film bags. The former has the characteristics of light weight, high strength, and corrosion resistance. After adding plastic film lining, it can prevent moisture and moisture; the load capacity of light bags is below 2.5kg, the load capacity of medium bags is 25-50kg, and the load capacity of heavy bags is 50-100kg. The latter has a light-duty bag with a load of more than 1kg; a medium-sized bag with a load of 1-10kg; a heavy-duty bag with a load of 10-30kg; and a container bag with a load of more than 1000kg. [0004] Packaging bags a...
