DETAILED DESCRIPTION

[0035] 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.

[0036] The utility model embodiment discloses a plastic packaging bag processing limiting mechanism. Figure 1-3 A plastic packaging bag processing limiting mechanism comprises a processing table 2, a cutting groove 1 is opened on the upper part of the processing table 2, a mounting frame 3 is arranged on the upper part of the processing table 2, a mounting plate 4 is arranged on the inner side of the mounting frame 3, a cutting component 5 for cutting the packaging bag is arranged on the mounting frame 3, a plurality of limiting components 6 for limiting and fixing the packaging bag are arranged on the mounting plate 4, and an adjusting component 7 for adjusting the position of the limiting component 6 is arranged on the rear side of the mounting plate 4;

[0037] Reference Figure 1 The cutting assembly 5 includes an electric push rod 501, a horizontal plate 502 and a cutting blade 503. The electric push rod 501 is arranged at the top of the mounting frame 3, the horizontal plate 502 is arranged at the bottom end of the electric push rod 501, and the rear side of the horizontal plate 502 is connected to the front side of the mounting plate 4. The cutting blade 503 is arranged at the bottom end of the horizontal plate 502 for cutting the packaging bag.

[0038] By adopting the above technical solution, the electric push rod 501 drives the horizontal plate 502 to move downward, and the downward movement of the horizontal plate 502 drives the cutting blade 503 and the mounting plate 4 to move downward, so that the cutting blade 503 can cut the plastic packaging bag.

[0039] Reference Figure 3 The limiting assembly 6 includes a guide block 601, a connecting plate 602, two T-shaped rods 603, an extrusion plate 604 and two springs 605. The guide block 601 is arranged on the front side of the mounting plate 4, the connecting plate 602 is arranged on one side of the guide block 601, the two T-shaped rods 603 are interspersed on the connecting plate 602, the extrusion plate 604 is arranged at the bottom ends of the two T-shaped rods 603, and the distance between the extrusion plate 604 and the upper part of the processing table 2 is smaller than the distance between the cross plate 502 and the upper part of the processing table 2. The two springs 605 are respectively sleeved on the outer sides of the corresponding T-shaped rods 603, and the two ends of the spring 605 are respectively connected to the connecting plate 602 and the extrusion plate 604.

[0040] By adopting the above technical solution, when the mounting plate 4 moves downward, the extrusion plate 604 will be driven downward, and the electric push rod 501 can drive the extrusion plate 604 and the cutting blade 503 to move downward synchronously. Since the extrusion plate 604 is closer to the upper part of the processing table 2, the extrusion plate 604 will first contact the plastic packaging bag to limit and fix the plastic packaging bag, thereby ensuring that the plastic packaging bag is not easily displaced during cutting.

[0041] Reference Figure 3 The adjustment component 7 includes two mounting blocks 701, a bidirectional screw 702, two threaded sleeves 703 and a handle 704. The two mounting blocks 701 are symmetrically arranged on the rear side of the mounting plate 4. The bidirectional screw 702 is rotatably arranged between the two mounting blocks 701. The two threaded sleeves 703 are both threadedly arranged on the bidirectional screw 702. One end of the guide block 601 passes through the mounting plate 4 and is connected to one end of the threaded sleeve 703. The handle 704 is rotatably arranged on one side of the corresponding mounting block 701, and one end of the handle 704 is connected to one end of the bidirectional screw 702.

[0042] By adopting the above technical solution, during the process of cutting the plastic packaging bags, the staff can rotate the handle 704 to drive the bidirectional screw 702 to rotate, and the rotation of the bidirectional screw 702 can drive the two threaded sleeves 703 to move. The movement of the threaded sleeve 703 can drive the extrusion plate 604 to move through the guide block 601, making it convenient to limit and fix plastic packaging bags of different sizes.

[0043] Reference Figure 3 A guide groove 8 is provided on the mounting plate 4 for the guide block 601 to move, and one end of the guide block 601 passes through the guide groove 8 and is slidably connected to the guide groove 8.

[0044] By adopting the above technical solution, the guide block 601 can be more stable when the threaded sleeve 703 moves to drive the guide block 601 to move.

[0045] Reference Figure 2 and Figure 3 Slide blocks 9 are provided on both sides of the mounting plate 4, and matching slide grooves 10 are provided on both ends of the inner side of the mounting frame 3. One end of the slide block 9 penetrates into the slide groove 10 and is slidably connected with the slide groove 10.

[0046] By adopting the above technical solution, the sliding block 9 slides in the sliding groove 10, thereby greatly ensuring the stability of the mounting plate 4 when it moves.

[0047] Working principle: When the utility model is in use, the electrical components appearing in the present application are all connected to an external power supply and a control switch. First, the plastic packaging bag to be cut is placed on the processing table 2, and then the electric push rod 501 works to drive the horizontal plate 502 to move downward, and the downward movement of the horizontal plate 502 drives the cutting blade 503 and the mounting plate 4 to move downward. Since the extrusion plate 604 is closer to the upper part of the processing table 2, the extrusion plate 604 will first contact the plastic packaging bag to limit and fix the plastic packaging bag, and then as the horizontal plate 502 and the mounting plate 4 continue to move downward, the extrusion plate 604 is squeezed to push the T-shaped rod 603 to move upward and squeeze the spring 605, and then the cutting blade 503 and the plastic packaging bag are in contact. When the plastic packaging bag contacts the plastic packaging bag, it can be cut. During the entire cutting process, the extrusion plate 604 always keeps the plastic packaging bag in a limited and fixed state, which ensures the cutting effect of the plastic packaging bag. After the cutting is completed, the cross plate 502 and the mounting plate 4 move up. At this time, the extrusion plate 604 can be reset by the spring 605, which is convenient for continuing the cutting work next time. In the cutting process, the staff can rotate the handle 704 to drive the bidirectional screw 702 to rotate. The rotation of the bidirectional screw 702 can drive the two threaded sleeves 703 to move. The movement of the threaded sleeve 703 can drive the extrusion plate 604 to move through the guide block 601, so that it is convenient to limit and fix plastic packaging bags of different sizes.

[0048] When the utility model is in use, the plastic packaging bag can be automatically limited and fixed during the process of cutting it, and the staff does not need to manually limit and fix the plastic packaging bag, which greatly reduces the labor intensity of the staff. At the same time, it is convenient to adjust the use position of the extrusion plate 604, so as to facilitate the limit and fixation of plastic packaging bags of different sizes.
