Description

Technical Field

[0001] The utility model belongs to the technical field of carton color printing, in particular to a fixing device for carton color printing. Background Art

[0002] According to the patent document with the authorization announcement number "CN213167126U" and the invention name "A fixing device for carton color printing", its description states: the mounting holes evenly distributed at the bottom of the supporting legs are connected to the mounting parts by bolts to achieve stability of the upper structure. The electric telescopic column is operated by controlling the switch group. According to the size of the processed carton, the electric telescopic column is regulated to shrink or extend, so that the left mounting plate moves left or right on the annular slide rail. The rotating piece rotates through the rotation connection of the connecting rod one, so that the right mounting plate connected to the rotating connecting rod two moves left or right on the annular slide rail. The two mounting plates are on the annular slide rail. The moving directions on the rails are opposite, but always maintain symmetry. The cardboard can be better fixed by the clamping plates on the two mounting plates. The two motors are running, and the output speed and direction of the two motors are consistent. The output shafts of the two motors drive the two multi-stage pulleys to rotate. The other two pulleys are connected by the belt transmission, thereby driving the rotating shaft to rotate, and the pulleys distributed on the two mounting plates are rotated to transport the cartons above. The cartons can be automatically transported, which improves work efficiency and reduces the workload of external personnel. After the work is completed, all structures stop and each structure is reset through the control of the control switch group. However, the following defects still exist:

[0003] When fixing the carton, only two clamping plates are used to clamp the two sides of the carton, which has a small clamping surface and may result in poor clamping stability. Utility Model Content

[0024] The first clamping assembly 8 includes a support plate 801 arranged on the inner side of the C-shaped frame 2, and a clamping plate 802 is fixedly installed on the top of the support plate 801. The support plate 801 is slidably connected to the guide rod 4. The two support plates 801 are respectively threadedly connected to two thread grooves opened in opposite directions on the double-headed screw 5. Suction cups 803 are evenly installed on the top of the support plate 801, and connecting grooves 804 are evenly opened inside the support plate 801. The suction cups 803 are connected to the connecting grooves 804. A piston 805 is movably installed inside the connecting groove 804. A pull rod 806 is fixedly installed on the bottom end of the piston 805. The bottom end of the pull rod 806 extends to the bottom of the support plate 801, and a pull plate 807 is fixedly installed on the bottom end of the pull rod 806.

[0025] The second clamping assembly 9 includes a swivel 901 rotatably mounted on the middle part of the outer side of the connecting shaft 7, a clamping rod 902 is fixedly mounted on the top of the swivel 901, a bottom plate 903 is fixedly mounted on the bottom end of the swivel 901, a connecting block 904 is provided below the middle of the double-headed screw 5, and connecting rods 905 are respectively provided between the two sides of the connecting block 904 and the two bottom plates 903. The two ends of the connecting rod 905 are respectively hinged to the side walls of the connecting block 904 and the bottom plate 903, and the end of the connecting rod 905 close to the bottom plate 903 is tilted downward, and side rods 906 are symmetrically mounted on both ends of the connecting block 904, a guide ring 907 is fixedly mounted on the bottom end of the pull plate 807, and the side rod 906 is movably mounted inside the guide ring 907. The end of the guide ring 907 is fixedly mounted with an end plate 908, and the bottom end of the end plate 908 is connected to the cylinder 90 9, the output end is fixedly connected, the cylinder 909 is fixedly mounted on the base 1, and the two supporting plates 801 are driven by the motor 6 to approach each other, so that the two clamping plates 802 clamp the two sides of the carton, and the cylinder 909 drives the connecting block 904 to move downward, and drives the swivel 901 to rotate through the connecting rod 905, so that the two clamping rods 902 clamp the other two sides of the carton, which is convenient for clamping cartons of different sizes and improving the stability of color printing. The guide ring 907 at the bottom of the pull plate 807 is slidably connected to the side rod 906. When the supporting plate 801 moves, the side rod 906 moves downward and can still pull the pull plate 807 downward. When the pull plate 807 moves downward, it drives the piston 805 to move downward, so that negative pressure is generated between the suction cup 803 and the carton, further fixing the carton and improving the stability of color printing.

[0026] Working principle: When working, first place the carton to be fixed with color printing on the top of the two supporting plates 801, so that the bottom wall of the carton contacts the end wall of the suction cup 803, turn on the motor 6, thereby driving the double-headed screw 5 to rotate. Since the two supporting plates 801 are respectively threadedly connected to the two thread grooves on the double-headed screw 5 with opposite directions, the two supporting plates 801 are driven to move closer to each other, so that the two clamping plates 802 clamp the two sides of the carton;

[0027] Then, the cylinder 909 is turned on, so that the output end of the cylinder 909 retracts, thereby pulling the side rod 906 downward. Since the guide ring 907 at the bottom end of the pull plate 807 is slidably connected to the side rod 906, the pull plate 807 can still be pulled downward when it moves. The end plate 908 moves downward, causing the connecting block 904 to move downward, thereby pushing the swivel 901 to rotate around the connecting shaft 7 through the connecting rod 905, so that the two clamping rods 902 clamp the other two sides of the carton, making it convenient to clamp cartons of different sizes.

[0028] When the pull plate 807 moves downward, the piston 805 is pulled downward. Since the connecting groove 804 is connected to the suction cup 803, the end surface of the suction cup 803 contacts the bottom wall of the carton, so that a negative pressure adsorption force is generated between the suction cup 803 and the carton, thereby further fixing the carton.

[0029] The color printing machine is then moved downward to print color on the top wall of the carton.
