[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0043] Please refer to Figures 1-3 The present application provides the following technical solutions:

[0044] A bag cutting mechanism includes two parallel cutting assemblies 1, the cutting direction of the cutting assembly 1 and the conveying direction of the material are perpendicular, and a gap is left between the two cutting assemblies 1, which corresponds to the width of the bag to be cut. In operation, the two cutting assemblies 1 cut one edge of the bag respectively. The cutting assembly 1 is connected with a cutting support assembly 2, which supports the cutting assembly 1. In order to adjust the distance between the cutting assemblies 1, the cutting assembly 1 is slidingly connected with the cutting support assembly 2, and the sliding direction of the cutting assembly 1 and the cutting support assembly 2 is parallel to the conveying direction of the material. The cutting assembly 1 is linked with a cutting drive assembly 3, which can drive the cutting assembly 11 to perform opening and closing cutting actions.

[0045] See Figure 1 A protective shell 34 is arranged at the installation position of the mechanism, and the cutting support assembly 2 is movably connected with the protective shell 34. Part of the structure of the cutting drive assembly 3 is arranged in the protective shell 34.

[0046] The cutting assembly 1 includes a first cutting member 11 and a second cutting member 12. The first cutting member 11 is approximately "L" shaped in main body, including a vertically arranged cutting baffle. The lower part of the second cutting member 12 is movably connected with the lower part of the first cutting member 11, and the second cutting member 12 can rotate towards or away from the cutting baffle of the first cutting member 11. The opening and closing of the first cutting member 11 and the second cutting member 12 form a scissor-type cutting action, which can cut the continuous packaging bag. By sliding the two cutting assemblies 1, the distance between them can be adjusted, so that the cutting of bags of different widths can be realized. This process does not need to remove the mechanism on the production line, but only needs a simple sliding action, which is very flexible and convenient to adjust.

[0047] On the basis of the above-mentioned embodiments, see Figure 2 and Figure 3 The cutting support assembly 2 includes a sliding frame 21 and a swing frame 22. The sliding frame 21 and the swing frame 22 are both connected with the protective shell 34, and the lower part of the first cutting member 11 is movably connected with the sliding frame 21, and the sliding direction is parallel to the conveying direction of the material. The swing frame 22 is arranged between the cutting assembly 1 and the cutting drive assembly 3, and the second cutting member 12 is linked with the swing frame. The cutting drive assembly 3 drives the second cutting member 12 to rotate through the swing frame 22, so as to realize the execution of the cutting action.

[0048] Based on the above implementation scheme, the sliding frame 21 includes a sliding rod 211, which is a horizontally arranged long strip rod with its length direction parallel to the material conveying direction; the first cutting piece 11 and the sliding rod 211 are slidably connected, and the sliding direction of the first cutting piece 11 and the sliding rod 211 is the length direction of the sliding rod 211.

[0049] The sliding rod 211 is dovetail-shaped, and the first cutting piece 11 has a corresponding dovetail groove. The two are connected through the dovetail groove, which can ensure that they slide without separating.

[0050] Based on the above implementation plan, see Figure 2 and Figure 3 The swing frame 22 is generally U-shaped and includes a rotating shaft 221. The rotating shaft 221 is rotatably connected to the protective shell 34, and the rotating shaft 221 is linked to the cutting drive assembly 3, which can drive the rotating shaft 221 to reciprocate. A swing rod 222 is arranged parallel to the rotating shaft 221. The two ends of the swing rod 222 and the rotating shaft 221 are connected by two intermediate rods. The lower end of the intermediate rod is fixedly connected to the rotating shaft 221, and the upper end can be rotatably or fixedly connected to the swing rod 222. The swing rod 222 is linked to the second cutting piece 12 of the cutting assembly 1. The reciprocating swing of the swing frame 22 drives the opening and closing movement of the second cutting piece 12 and the first cutting piece 11.

[0051] Two hinges are provided between the swing arm 222 and the second cutting member 12. One hinge connects to the connecting frame on the side of the second cutting member 12, and the other hinge connects to the swing arm 222. The connecting frame of the second cutting member 12 and the second cutting member 12 are detachably connected. Because the second cutting member 12 is provided with a cutting edge, this connection method makes maintenance of the second cutting member 12 more convenient. The swinging motion of the swing arm 22 transmits the swinging force to the second cutting member 12 through the two hinges, thereby achieving the opening and closing cutting effect of the scissors.

[0052] Based on the above implementation scheme, in addition to the sliding connection between the first cutting component 11 and the sliding rod 211, the swing rod 222 and the aforementioned hinge are also slidably connected. The sliding direction of the two is the length direction of the swing rod 222. When it is necessary to adjust the distance between the two cutting components 1, the positions of the first cutting component 11 and the second cutting component 12 can be adjusted simultaneously.

[0053] Based on the above implementation plan, see Figure 2 and Figure 3The cutting driving assembly 3 comprises a main connecting shaft 33 and a first driving assembly 31. The main connecting shaft 33 is fixedly connected with the external supporting structure, and the first driving assembly 31 is used to drive the rotation of the rotating shaft 221. The first driving assembly 31 comprises a first rocker 313 rotatably connected with the main connecting shaft 33. The middle part of the first rocker 313 is rotatably connected with the main connecting shaft 33, and the upper side of one end of the first rocker 313 is provided with a first cam 314. The first cam 314 is linked with the external driving assembly, and the first cam 314 is driven to rotate by the external driving assembly. The outer side surface of the first cam 314 is in contact with the upper side surface of the first rocker 313. The other end of the first rocker 313 is provided with a first pull rod 312. The lower end of the first pull rod 312 is rotatably connected with the first rocker 313, and the upper end of the first pull rod 312 is rotatably connected with one end of a first linkage rod 311. The other end of the first linkage rod 311 is fixedly connected with the rotating shaft 221.

[0054] With the rotation of the first cam 314, the first rocker 313 reciprocatingly swings. The swinging force of the first rocker 313 is transmitted to the rotating shaft 221 through the first pull rod 312 and the first linkage rod 311, so that the rotating shaft 221 reciprocatingly rotates, and the swing frame 22 swings.

[0055] On the basis of the above-mentioned embodiment, the sliding rod 211 is slidably connected with the protective shell 34. The sliding frame 21 further comprises a moving rod 212. The moving rod 212 is arranged on the side of the sliding rod 211 away from the first cutting element 11. The moving rod 212 is fixedly connected with the sliding rod 211 and slidably connected with the protective shell 34. The sliding direction of the moving rod 212 is perpendicular to the length direction of the sliding rod 211 and is horizontal.

[0056] Through the above structure, the position of the sliding frame 21 can be adjusted, and the flexibility and adaptability of the mechanism are enhanced.

[0057] On the basis of the above-mentioned embodiment, the cutting driving assembly 3 further comprises a second driving assembly 32. The second driving assembly 32 is used to drive the reciprocating movement of the sliding frame 21 in the horizontal direction. The reciprocating movement of the second driving assembly 32 in the horizontal direction is perpendicular to the conveying direction of the bag to be cut.

[0058] The second driving assembly 32 comprises a second rocker 321, which is also rotationally connected with the main connecting shaft 33 and is arranged at the middle part. A second cam 322 is arranged at one end of the second rocker 321, and the second rocker 321 is driven to reciprocate by the rotation of the second cam 322. A second pull rod is arranged at the other end of the second rocker 321, and the second pull rod is connected with the moving rod 212 through a linkage assembly. The moving rod 212 is driven to reciprocate in the horizontal direction by the reciprocating movement of the second pull rod, so as to drive the sliding frame 21 to reciprocate. For the specific structure of the linkage assembly, the existing linkage structure can be used, for example, the upper end of the second pull rod is ball-hinged with a rotating block, a spherical part for ball-hinge connection is arranged on the rotating block, and the spherical part is arranged at the eccentric position of the rotating block. A clamping block is connected with the rotating block through a short connecting rod, the two ends of the short connecting rod are respectively hinged with the rotating block and the clamping block, and the clamping block clamps the moving rod 212. A positioning member is sleeved on the moving rod 212, the positioning member is slidingly connected with the moving rod 212, and the positioning member is fixedly arranged on the protective shell 34. Through this structure, the linkage between the second cam 322 and the moving rod 212 can be realized, so that the moving rod 212 is driven to reciprocate by the second cam 322. The second cam 322 and the first cam 314 can be coaxially arranged, and the two are coaxially rotated by the external driving member, so as to realize the cooperation between the translational movement of the first cutting member 11 and the swinging movement of the second cutting member 12.

[0059] Through this structure, when the second cutting member 12 performs the cutting action, the sliding frame 21 drives the first cutting member 11 to move laterally in a small amplitude, so as to improve the cutting force during the execution of the cutting action and ensure that the bag can be better cut. Through the structure of the present application, the second cutting member 12 performs the swinging action, and the first cutting member 11 performs the lateral translation, so as to realize the cutting and dividing of the scissors while reducing the space occupied by the translation side, to give the position of other mechanisms of the packaging machine and reduce the transfer distance of the packaging bag.
