Description

Technical Field

[0001] This utility model relates to the field of packaging winding equipment technology, and in particular to a winding mechanism for a color packaging printing machine. Background Technology

[0002] In the color packaging printing industry, the winding mechanism is an indispensable and important component of the printing press. Its main function is to neatly and tightly wind the printed packaging materials into rolls for subsequent storage, transportation and processing. As the packaging market continues to increase its requirements for product appearance and quality, the performance of the winding process directly affects the quality of the final product and production efficiency.

[0003] Currently, traditional winding mechanisms in color packaging printing presses have many shortcomings in practical applications. During the winding process, the packaging material needs to be wound up after printing. However, due to the characteristics of the material itself and the tension changes during transmission, the packaging material is prone to wrinkles. This not only leads to unevenness of the wound roll, affecting the smooth progress of subsequent processing steps, but may also cause material damage due to uneven stress at the wrinkles, increasing production costs. At the same time, when cutting is required after winding to a certain length, the stability of the cutting components is insufficient, and deviation is prone to occur, resulting in uneven cut edges, further affecting product quality. In addition, during the winding process, the packaging material may also shift and overflow from both ends of the winding roller, making the edges of the roll uneven and reducing the regularity of the product. Therefore, the above problems need to be solved. Utility Model Content

[0023] Working principle: When using this utility model, the base 1 is placed on the predetermined base surface through the fixing platform 2. This product is divided into an installation process and a normal working principle process.

[0024] Installation Procedure: Except for the take-up roller 26, first abutment platform 24, second abutment platform 25, and second electric push cylinder 22 (which require replacement, as the take-up roller 26 requires the cooperation of the first abutment platform 24 and the second abutment platform 25), all other components are pre-assembled by the manufacturer. Power on the equipment and activate the lifting cylinder 17 located at the lower end of the first lifting platform 18 and installed inside the take-up platform 5 to lift the first lifting platform 18. Connect the first abutment platform 24 via the coupling installed on the drive end of the first electric push cylinder 23. Fit the second abutment platform 25 onto the other side of the take-up roller 26. Then, sequentially pass one side of the take-up roller 26 through the first abutment platform 24 to open... The hole is connected to the coupling installed at the drive end of the take-up motor 20. The lifting cylinder 17 at the lower end of the first lifting platform 18 is reset so that the other side of the take-up roller 26 is placed on the second lifting platform 19. Alternatively, the lifting cylinder 17 at the lower end of the second lifting platform 19 can be activated to lift the second lifting platform 19 so that the other side of the take-up roller 26 is placed on the second lifting platform 19. Then, the fixing block 21 is fixed through the slot opened in the second lifting platform 19. The second electric push cylinder 22 is fixed on the fixing block 21. Then, the second abutment platform 25, which was previously sleeved on the other side of the take-up roller 26, is connected through the coupling installed at the drive end of the second electric push cylinder 22. The installation is then complete.

[0025] Normal operating procedure: After the equipment is installed and the printing press finishes printing, the package passes under the limiting roller 8, then between the lead screw 11 and the guide rod 14, connecting the end of the package to the take-up roller 26. The take-up motor 20 is started, driving the take-up roller 26 to rotate and begin winding the package. Since the package passes under the limiting roller 8, which is mounted on the connecting platform 7 and driven by the spring 9 within the limiting platform 3, and the limiting roller 8 can slide up and down within the displacement groove 6, the packages passing under the limiting roller 8 are flat and taut, providing stability for the take-up roller 26. Because the package may slide on the take-up roller 26 during winding, a laser sensor installed in the placement platform 15 is used. Device 16 will be installed in a predetermined position to detect the take-up roller 26. When it is detected that the packaging overflows from the take-up roller 26 (whether it is on one side or the other side of the take-up roller 26), the take-up motor 20 will slow down and start the first electric push cylinder 23 and the second electric push cylinder 22 to drive the first abutment platform 24 and the second abutment platform 25 so that the overflowed packaging returns to the range of the take-up roller 26. After the take-up is completed, the cutting motor 12 installed on one side of the cutting table 4 will be started. The cutting motor 12 drives the lead screw 11 located in the mounting groove 10 to rotate. The lead screw 11 drives the cutting block 13. After the guide rod 14 limits the cutting block 13, it will cut the packaging smoothly. After the last end of the packaging is finished being taken up by the take-up roller 26, the take-up motor 20 will be turned off. The take-up roller 26 will be removed and placed in reverse order of the installation process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
