[0031] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0032] like Figure 1 to Figure 4 As shown, a cutting device of the utility model comprises a supporting seat 1, which is provided with a working table for placing packaging bags; a placing frame 2, which is installed in the middle of the top of the supporting seat 1; a driving mechanism, which is installed on the placing frame 2; a mounting seat 31, which is connected to the driving mechanism, and the driving mechanism drives the mounting seat 31 to rise and fall relative to the working table; a cutting knife 33, which is installed on the mounting seat 31; and a pressing component, which is installed on the mounting seat 31, and the pressing component presses the packaging bag against the working table when the mounting seat 31 descends, and retracts to allow the cutting knife 33 to cut the packaging bag.

[0033] By coordinating the supporting seat 1, the placing rack 2, the mounting seat 31, the cutting knife 33, the driving mechanism and the pressing assembly, the mounting seat 31, the cutting knife 33 and the pressing assembly can be synchronously driven by the driving mechanism to move in the vertical direction of the placing rack 2, so that the cutting work can be completed during the process of pressing the packaging bag, thereby improving the working efficiency of the device.

[0034] In some embodiments, the driving mechanism includes a driving motor 41, a driving rod 42 and a moving rod 43. The driving motor 41 is installed at the middle of one end of the placement rack 2 facing the supporting seat 1. The output shaft of the driving motor 41 is fixedly connected to the driving rod 42. The outer side of the driving rod 42 is threadedly connected to the moving rod 43. The end of the moving rod 43 away from the driving rod 42 is fixedly connected to the top of the mounting seat 31.

[0035] The driving motor 41 is started, and the output shaft of the driving motor 41 rotates, thereby driving the driving rod 42 to rotate, and then the moving rod 43 moves up and down, thereby driving the mounting seat 31 to move.

[0036] In some embodiments, guide grooves 51 are provided on both the left and right inner walls of the placement rack 2 , and guide blocks 52 are provided on both the left and right ends of the mounting seat 31 , and the guide blocks 52 are slidably installed in the guide grooves 51 .

[0037] When the mounting seat 31 moves, the guide block 52 is driven to slide in the guide groove 51 . Due to the limitation of the guide groove 51 , the moving rod 43 can only move up and down, which is beneficial to improving the moving effect of the mounting seat 31 .

[0038] In some embodiments, a mounting groove 32 is formed at one end of the mounting seat 31 facing the cutting blade 33 . The top end of the cutting blade 33 is mounted in the mounting groove 32 , and the bottom end of the cutting blade 33 is exposed from the mounting seat 31 and faces the supporting seat 1 .

[0039] The cutting blade 33 and the mounting seat 31 can be installed and removed, so as to facilitate maintenance and replacement.

[0040] In some embodiments, there are two pressing components, which are symmetrically arranged front and back relative to the mounting seat 31 .

[0041] In some embodiments, the pressing assembly includes a mounting plate 61, a pressing plate 62 and multiple elastic components, the end of the mounting plate 61 is fixedly connected to the mounting seat 31, and the end of the mounting plate 61 facing the supporting seat 1 is connected to the multiple elastic components, and the end of the elastic component away from the mounting plate 61 is connected to the pressing plate 62.

[0042] When the mounting seat 31 moves toward the bearing seat 1 , the mounting plate 61 , the pressing plate 62 and the elastic component are also driven to move toward the bearing seat 1 , so that the packaging bag can be cut while being pressed.

[0043] In some embodiments, the number of elastic components is three, and the three elastic components are arranged at equal intervals along the horizontal direction of the mounting plate 61.

[0044] In some embodiments, the elastic component includes a fixed rod 71, a sliding rod 72 and a return spring 73. The top end of the fixed rod 71 is fixedly connected to the mounting plate 61. A sliding groove 74 is provided at one end of the fixed rod 71 facing the sliding rod 72. The top end of the sliding rod 72 is slidably installed in the sliding groove 74, and the end of the sliding rod 72 located outside the sliding groove 74 is connected to the pressing plate 62. The return spring 73 is located in the sliding groove 74, and the upper and lower ends of the return spring 73 are respectively connected to the inner wall of the sliding groove 74 and the sliding rod 72.

[0045] When the mounting seat 31 moves toward the supporting seat 1, the pressing plate 62 first contacts the packaging bag to realize the pressing function, and then the mounting seat 31 continues to move toward the supporting seat 1, so that the sliding rod 72 moves into the sliding groove 74 and squeezes the return spring 73. When the cutting knife 33 reaches the cutting position, the mounting seat 31 no longer moves. At this time, the pressing and cutting work is completed, which will result in; when the mounting seat 31 moves upward away from the supporting seat 1, the pressing plate 62 and the sliding rod 72 return to their initial state through the elastic action of the return spring 73.

[0046] The method of using the utility model is as follows:

[0047] When in use, the packaging bag is first placed on the supporting seat 1, and then the driving motor 41 is started. The output shaft of the driving motor 41 rotates, thereby driving the driving rod 42 to rotate, and then the moving rod 43 moves downward, thereby driving the mounting seat 31 to move.

[0048] The pressing plate 62 and the cutting knife 33 are driven to move toward the packaging bag through the mounting seat 31. The pressing plate 62 first contacts the packaging bag to achieve a preliminary pressing function. Then the mounting seat 31 continues to move toward the supporting seat 1, and then the sliding rod 72 moves into the sliding groove 74. When the cutting knife 33 reaches the cutting position, the mounting seat 31 no longer moves downward, thereby completing the pressing and cutting of the packaging bag.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
