[0026] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] For the convenience of understanding, please refer to Figures 1 to 4, this embodiment provides a fixing device for processing cartons of different sizes, including limiting plates 2 located in the front, back, left, and right directions of the workbench surface 1. Four sliding grooves 3 are provided on the front surface of the limiting plate 2 (i.e., the contact surface with the carton). Stretch bars 4 are respectively slidably connected to the sliding grooves 3. Buffer pads are provided on the contact surfaces of the limiting plate 2 and the stretch bars 4 with the carton. The material of the buffer pad is preferably EVA (ethylene-vinyl acetate copolymer) material. The buffer pad can buffer the pressure of the limiting plate 2 and the stretch bars 4 on the carton wall, avoiding damage to the carton wall caused by excessive pressure. The stretch bars 4 can be extended and stretched in the up, down, left, and right directions from within the limiting plate 2, expanding the coverage range of the limiting plate 2 on the carton wall and improving the fixing effect of the limiting plate 2 on the carton, being applicable to cartons of different specifications and sizes. A rack 5 is provided in the sliding groove 3, and a sliding elastic piece 6 is provided at the end of the stretch bar 4 correspondingly. The sliding elastic piece 6 includes a protruding portion 61 that abuts against the rack 5 and a clamping portion 62 for clamping and fixing the sliding elastic piece 6 at the end of the stretch bar 4. The sliding elastic piece 6 is clamped and fixed at the end of the stretch bar 4 through the clamping portions 62 on both sides. The protruding portion 61 of the sliding elastic piece 6 abuts against the rack 5. As the stretch bar 4 slides in the sliding groove 3, the sliding elastic piece 6 will move along with the stretch bar 4 on the rack 5. The sliding elastic piece 6 is used to fix the sliding position of the stretch bar 4, avoiding accidentally touching the stretch bar 4 when the limiting plate 2 moves or during the carton processing, resulting in the stretch bar 4 retracting or extending by itself and deviating from the pre-set sliding position of the stretch bar 4, thereby affecting the fixing effect of the limiting plate 2 on the carton or interfering with the carton processing operation.

[0028] For ease of understanding, please continue to refer to Figure 1 and Figure 4, a first driving mechanism is connected to the back surface of the limiting plate 2. The first driving mechanism is a first electric push rod 7. The first electric push rod 7 can drive the limiting plate 2 to move in the horizontal direction. The extending end of the first electric push rod 7 is fixedly connected to the hinge plate 8. The hinge plate 8 is hingedly connected to the back surface of the limiting plate 2. The limiting plate 2 can rotate relative to the hinge plate 8 in the vertical direction. When the first electric push rod 7 is started, the extending end of the first electric push rod 7 advances forward, driving the hinge plate 8 to move horizontally forward, and then driving the limiting plate 2 to move horizontally forward until the limiting plate 2 abuts against the wall of the carton, fixing the carton from the horizontal surrounding directions. With the increasing popularity of the concept of ecological environmental protection, carton manufacturers, aiming at unnecessary resource waste, have started to design and produce corresponding packaging cartons specifically according to objects with different shapes and structures. Therefore, some non-square cartons (such as trapezoidal cartons) have appeared on the market currently. Since the limiting plate 2 can rotate in the vertical direction, when fixing a non-square carton, the front angle of the limiting plate 2 can be rotated and adjusted until the front surface of the limiting plate 2 approaches a parallel state relative to the wall of the carton, making the limiting plate 2 and the stretching strip 4 fit completely with the wall of the carton, further improving the fixing effect of the limiting plate 2 and the stretching strip 4 on the carton, and being applicable to cartons with different shapes and structures.

[0029] For the sake of easy understanding, please continue to refer to Figure 1 and Figure 4 , the frame 12 is located below the workbench surface 1. Adjusting rods 9 are respectively connected to the frame 12 along the surrounding directions of the workbench surface 1. The adjusting rods 9 are L-shaped rods. The vertical rod is fixedly connected to the base of the first electric push rod 7, and the horizontal rod is sleeved inside the frame 12. The frame 12 is provided with a plurality of through holes 10 at the connecting part with the adjusting rods 9. A plurality of adjusting holes 13 are provided on the horizontal rods corresponding to the adjusting rods 9. The frame 12 and the horizontal rods of the four adjusting rods 9 are connected and fixed by bolts. The extending length of the horizontal rod of the adjusting rod 9 is adjusted by the docking method of different through holes 10 and adjusting holes 13, that is, the horizontal length of each adjusting rod 9 is adjusted, and then the relative distance between the two limiting plates 2 in the same direction is adjusted to adapt to cartons with different size ranges.

[0030] For the sake of easy understanding, please continue to refer to Figure 1 and Figure 4, a second driving mechanism is connected below the frame 12. The second driving mechanism is a second electric push rod 11. The extending end of the second electric push rod 11 is fixedly connected to the middle part below the frame 12. The second electric push rod 11 can drive the frame 12 to move up and down in the vertical direction. When the second electric push rod 11 is started, the extending end of the second electric push rod 11 advances upward, driving the frame 12 to move vertically upward, and then driving the adjusting rod 9, the first electric push rod 7, the limiting plate 2 and the stretching strip 4 to move vertically upward together until the center of the front surface of the limiting plate 2 approaches the horizontal position in the middle of the cardboard box wall, so that the limiting plate 2 can cover the center of the cardboard box wall, further improving the fixing effect of the limiting plate 2 and the stretching strip 4 on the cardboard box.

[0031] The using method of the utility model: First, the staff adjusts the height of the four limiting plates 2 on the workbench surface 1 through the second electric push rod 11 according to the height dimension of this batch of cardboard boxes to be processed, so that the center of the front surface of the limiting plate 2 approaches the horizontal position in the middle of the cardboard box wall of this batch. Then, according to the length dimension and width dimension of this batch of cardboard boxes to be processed, the horizontal lengths of the respective adjusting rods 9 are adjusted by means of docking different through holes 10, and then the relative distances of the limiting plates 2 in the length direction and the width direction are respectively adjusted to make the limiting plates 2 approach the cardboard box wall to be processed. After that, according to the shape structure of this batch of cardboard boxes to be processed, the angle of the limiting plate 2 is rotated until the front surface of the limiting plate 2 approaches a parallel state relative to the cardboard box wall. Finally, according to the sizes of the four surrounding cardboard box walls of this batch of cardboard boxes to be processed, the stretching strips 4 are respectively slid out from within the limiting plates 2 to maximize the coverage range of the four limiting plates 2 on the four surrounding cardboard box walls, that is, the pre-positioning action of the fixing device is completed; At this time, the staff (or an automated device) moves the first cardboard box to be processed onto the workbench surface 1, and sequentially turns on the first electric push rods 7 to drive the surrounding limiting plates 2 and the stretching strips 4 to abut against the cardboard box wall. At this time, the fixing action of the first cardboard box is completed, and the processing action on the cardboard box after the fixing action is completed can be started. After the processing action of the first cardboard box is completed, only the first electric push rods 7 need to be reset in sequence to drive the four limiting plates 2 to retreat and reset, so that the processed cardboard box can be taken out, and the second cardboard box to be processed can be moved onto the workbench surface 1. By repeating the above operations, a batch of cardboard boxes to be processed can be fixed and processed.
