Detailed Description
The technical solution of the present utility model will be described in further detail with reference to the accompanying drawings, but the scope of the present utility model is not limited to the following description.
As shown in fig. 1 and 2, an adaptive opposite cutter comprises a fixed cutter assembly and a movable cutter blade 1. The fixed cutter assembly comprises a fixed cutter seat 3, a fixed cutter blade 2, a connecting piece, a first elastic piece 4 and a second elastic piece 5, wherein the middle part of one side of the fixed cutter blade 2 is connected with the fixed cutter seat 3 through the connecting piece, the fixed cutter blade 2 can translate towards the direction of the fixed cutter seat 3 and can swing by taking the connecting piece as the center, the first elastic piece 4 and the second elastic piece 5 are respectively arranged on two sides of the connecting piece, two ends of the first elastic piece 4 are respectively connected with the fixed cutter seat 3 and the fixed cutter blade 2, and two ends of the second elastic piece 5 are respectively connected with the fixed cutter seat 3 and the fixed cutter blade 2. The movable blade 1 is slidably arranged on one side of the fixed blade 2 away from the fixed blade holder 3, and in the process that the movable blade 1 moves towards the fixed blade 2 to cut, the fixed blade 2 can be tightly pressed towards the movable blade 1 under the elastic action of the first elastic piece 4 and the second elastic piece 5 as the fixed blade 2 can translate towards the fixed blade holder 3; because the fixed blade 2 can swing by taking the connecting piece as the center, under the elastic action of a deep sea self-stabilizing platform device, the swing angle of the fixed blade 2 can be adaptively adjusted, so that the self-adaptive fit between the side surface of the movable blade 1 and the side surface of the fixed blade 2 is always maintained in the whole cutting process, and the cutting effect is ensured.
In a specific implementation, the fixed blade 2 comprises a swing arm 6 and a fixed blade 7, one end of the swing arm 6 is fixedly connected with one end of the fixed blade 7, the swing arm 6 is basically vertical to the fixed blade 7, the middle part of the swing arm 6 is connected with the fixed blade holder 3 through a connecting piece, two ends of the first elastic piece 4 are respectively connected with the fixed blade holder 3 and the swing arm 6, and two ends of the second elastic piece 5 are respectively connected with the fixed blade holder 3 and the swing arm 6. The two swing arms 6 are arranged, and the two swing arms 6 are symmetrically arranged at two ends of the fixed blade 7. When the packaging bag is used, the packaging bag with the side seal and the bottom seal is positioned between the two swing arms 6, and in the process of moving the movable blade 1, the movable blade 1 can be always in self-adaptive fit with the bottom surface of the swing arm 6, no gap exists between the movable blade 1 and the bottom surface of the swing arm 6, and the packaging bag to be cut cannot be rolled between the fit surfaces of the movable blade 1 and the swing arm 6; when the movable blade of the movable blade 1 moves to the position of the fixed blade 7, the blades of the two blades are also positioned just opposite to each other, so that cutting is smoothly completed in the following interlacing process of the two blades.

Since the diameter of the limiting hole 10 is larger than that of the limiting post 9, the limiting post 9 can slide in the limiting hole 10, and the fixed blade 2 maintains the elastic force in the direction of the movable blade 1 under the elastic force of the first elastic piece 4 and the second elastic piece 5; since the diameter of the limiting hole 10 is larger than that of the limiting post 9, the limiting post 9 can deflect within a certain range in the limiting hole 10, so that the self-adaptive swing angle adjusting function is realized.
It should be noted that, the connection mode of the connecting piece is not limited to the specific implementation mode, for example, a limiting hole is formed in the swing arm 6, one end of the limiting hole, which is far away from the fixed tool apron 3, is communicated with a stepped hole, a nut is arranged in the stepped hole, the fixed tool apron 2 is pulled and limited by being connected with the connecting screw 8 through the nut, and the diameter of the limiting hole on the swing arm 6 is larger than the diameter of the limiting column through setting to realize self-adaptive fitting. It should also be understood that the connection is not limited to the form of the screw or bolt connection, as long as the technical function of translating the fixed blade 2 in the direction of the fixed blade holder 3 and swinging about the connection is achieved within the contemplation of the utility model.
In the specific implementation, the first elastic member 4 and the second elastic member 5 are springs, and two ends of each spring are respectively abutted against the fixed cutter seat 3 and the swing arm 6.
Further, the sliding direction of the movable blade 1 is perpendicular to the fixed blade 7, the movable blade 11 is disposed on the side of the movable blade 1 facing the fixed blade 7, and the movable blade 11 is disposed obliquely to the sliding direction of the movable blade 1, i.e. the movable blade 11 is not parallel to the fixed blade 7. When the packaging bag is cut, as the movable blade 1 moves forwards, the movable blade 11 and the fixed blade 7 are in a crossed state, and the packaging bag is cut at the crossing point, so that the structure has fewer blocks to overcome in the cutting process and is smoother to cut compared with a cutting mode similar to a scissors.
Fig. 3 is a view showing a state of use of the self-adaptive counter-knife for the bag making device, and two groups of self-adaptive counter-knives are provided to cut two packaging bags at the same time. During installation, the fixed cutter seat 3 is fixedly arranged on the frame, the movable cutter seat 12 is arranged on the frame in a sliding manner, the movable cutter 1 is arranged on the movable cutter seat 12, and the movable cutter seat 12 is driven by the driving mechanism to slide so as to drive the movable cutter 1 to move oppositely relative to the fixed cutter 2, so that cutting is completed.
