[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model discloses a plastic packaging bag cutting device. Figure 1-4 A plastic packaging bag cutting device comprises a processing table 1, a support plate 2 is arranged on the upper part of the processing table 1, an electric push rod 3 is arranged on the upper end of the support plate 2, a moving plate 4 is arranged on the lower end of the electric push rod 3, a cutting blade 5 is arranged at the middle part of the bottom end of the moving plate 4, a plurality of grooves 6 are opened at the bottom end of the moving plate 4, and a same positioning mechanism 7 is arranged between two grooves 6 on the same side;
[0021] The positioning mechanism 7 includes two cross bars 701, two sliders 702, two springs 703, two connecting rods 704, a connecting plate 705 and a positioning roller 706. The two cross bars 701 are respectively arranged in the corresponding grooves 6, and the two sliders 702 are respectively slidably arranged on the corresponding cross bars 701. The two springs 703 are respectively sleeved on the outer sides of the corresponding cross bars 701, and the two ends of the springs 703 are respectively connected to the sliders 702 and the inner walls of the grooves 6. The two connecting rods 704 are respectively hinged at the bottom ends of the corresponding sliders 702, the connecting plate 705 is hinged at the bottom end of the movable plate 4, and the bottom end of the connecting rod 704 is hinged to the side of the connecting plate 705, and the positioning roller 706 is rotatably arranged at the bottom end of the connecting plate 705.
[0022] By adopting the above technical solution, when cutting the packaging bag, the positioning roller 706 contacts the packaging bag and can press the packaging bag, so that the cut part of the packaging bag is not prone to wrinkles, and the packaging bag is not prone to shifting during the cutting process, which greatly ensures the cutting effect of the packaging bag.
[0023] Reference Figure 2 and Figure 3 Guide blocks 8 are provided on both the front and rear sides of the movable plate 4, and a plurality of guide grooves 9 are provided on the inner side of the support plate 2. One end of the guide block 8 penetrates into the guide groove 9 and is slidably connected with the guide groove 9.
[0024] By adopting the above technical solution, when the movable plate 4 moves downward, it will drive the guide block 8 to slide in the guide groove 9, so that the movable plate 4 is more stable when moving.
[0025] Reference Figure 3 A cutting groove 10 for use with a cutting blade 5 is provided on the upper portion of the processing table 1 .
[0026] By adopting the above technical solution, the cutting groove 10 makes it difficult to damage the processing table 1 when cutting the packaging bag.
[0027] Reference Figure 2 A relatively large sliding opening is retained at the hinge between the connecting rod 704 and the connecting plate 705 .
[0028] By adopting the above technical solution, when the connecting plate 705 rotates, the connecting rod 704 can push the sliding block 702 to slide on the cross bar 701.
[0029] Reference Figure 1 and Figure 3 A plurality of limiting plates 11 are provided on both the front and rear sides of the upper portion of the processing table 1 , and one side of the limiting plate 11 is connected to the supporting plate 2 .
[0030] By adopting the above technical solution, the limiting plate 11 can prevent the packaging bag from sliding off the processing table 1 .
[0031] Working principle: When the utility model is in use, the electrical components in the present application are all connected to an external power supply and a control switch. First, the packaging bag to be cut is placed on the processing table 1, and then the electric push rod 3 works to drive the moving plate 4 to move downward, and the moving plate 4 moves downward to drive the positioning roller 706 and the cutting blade 5 to move downward. At this time, the positioning roller 706 will first contact the packaging bag, and then as the moving plate 4 continues to move downward, the connecting plate 705 will rotate. At this time, the connecting rod 704 will drive the slider 702 to slide on the cross bar 701 and the spring 706 will rotate. 03 is squeezed, and the positioning roller 706 will always press the packaging bag during the whole process, so that the packaging bag is not easy to shift, and then the cutting blade 5 can cut the packaging bag after contacting the packaging bag. This cutting method makes it difficult for the cutting part of the packaging bag to be wrinkled, and makes it difficult for the packaging bag to shift during the cutting process, which greatly ensures the cutting effect of the packaging bag. Then, after the cutting is completed, the moving plate 4 moves up. At this time, the positioning roller 706 can be reset through the elastic force of the spring 703, which will not affect the subsequent use.
[0032] When the utility model is in use, the packaging bag can be fixed during the process of cutting the packaging bag, so that the packaging bag is not easy to deviate during cutting, and the cut part of the packaging bag is not easy to wrinkle, thus greatly ensuring the cutting effect of the packaging bag.
