Description

Technical Field

[0001] This utility model relates to the field of paper printing technology, specifically a folding mechanism for a printing press. Background Technology

[0002] Some printed materials need to be folded and trimmed before they can be made into the final product, such as newspapers, books, magazines, sample advertisements, etc. Folding is the process of folding large printed sheets into booklets by machine or by hand according to the page numbering order and the specified size. It is the main work of booklet making.

[0003] Chinese Utility Model Patent Publication No. CN222877315U discloses a fan-type folding mechanism for a printing press. The specification of this fan-type folding mechanism for a printing press describes a continuously rotating spiral wheel that causes paper to move downwards between spiral blades for folding. A power output shaft simultaneously drives the spiral wheel and a pressure wheel to rotate. The pressure wheel includes a semi-circular pressure plate protruding from its periphery. As the pressure wheel rotates, it presses the paper together through the pressure plate during folding, resulting in a consistent folding effect and more regular folded paper. However, this fan-type folding mechanism for a printing press lacks a quick-installation structure for the folding rod, making it inconvenient to adjust the position of the folding rod according to different paper lengths, thus resulting in significant limitations during the folding process. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a folding mechanism for printing presses, which can effectively solve the problem in the prior art that the lack of a quick-installation structure for the folding rod makes it inconvenient to adjust the position of the folding rod according to the length of different papers, resulting in a large overall limitation in the folding process.

[0005] The technical solution adopted by this utility model is: a folding mechanism for a printing machine, including a conveyor belt, a mounting base, a connecting plate, a width limiting component, and a blocking component. A fixing frame is fixedly installed at the end of the connecting plate away from the mounting base. A positioning plate is fixedly installed at the end of the fixing frame away from the connecting plate. A transmission component is fixedly installed at the end of the positioning plate away from the fixing frame. A connecting component is fixedly installed at the end of the transmission component away from the positioning plate. A through groove is opened at the inner edge of the conveyor belt, and the through groove is located directly below the connecting component.

[0006] The transmission assembly includes a transmission box, a servo motor is fixedly installed on the outer edge of the transmission box, a connecting shaft is fixedly installed on the output end of the servo motor, a transmission disk is fixedly installed on the other end of the connecting shaft away from the servo motor, and a connecting sleeve is fixedly installed on the other end of the transmission disk away from the connecting shaft.

[0007] The connecting assembly includes a lifting column, with a retaining sleeve fixedly installed at the end of the lifting column away from the transmission assembly, and a hinge rod engaged at the end of the retaining sleeve away from the lifting column.

[0008] Preferably, a connecting rod is fixedly installed at the end of the connecting sleeve one that is away from the transmission disc, and a connecting sleeve two is fixedly installed at the end of the connecting rod that is away from the connecting sleeve one, and the connecting sleeve two is fixedly installed with the lifting column.

[0009] Through the above technical solution, the rotational power of the servo motor is converted into the linear lifting motion of the lifting column by the cooperation of connecting sleeve one, connecting rod and connecting sleeve two, so that the folding rod moves up and down. When the printed paper reaches the bottom of the folding rod, the folding rod folds the paper.

[0010] Preferably, the lifting column and the transmission box are slidably connected, and the lifting column passes through the transmission box and extends to its inner edge.

[0011] The above technical solution, through the design of the lifting column and the transmission box, and the sliding connection between the two, facilitates the directional guidance of the lifting column, avoids easy shaking, and enables the lifting column to drive the folding rod to rise and fall along the preset trajectory, avoiding folding deviation caused by shaking.

[0012] Preferably, a mounting groove is provided at the outer edge of the folding rod, and multiple identical mounting grooves are provided, which are distributed at equal intervals.

[0013] Through the above technical solution, the design of multiple equally spaced mounting slots for the folding rod allows the position of the folding rod on the card holder to be adjusted according to the length of different papers when the folding rod is installed, which is convenient for covering the folding needs of papers of different sizes and thicknesses and improving overall versatility.

[0014] Preferably, the sleeve has a slot at one end near the folding rod, and a limit bolt is threadedly connected to the outer edge of the sleeve.

[0015] Through the above technical solution, the card slot design positions the folding rod in the card slot, and locks it with the limit bolt, realizing the fixation and quick disassembly of the folding rod. This not only prevents the folding rod from loosening or shifting during folding, but also facilitates later maintenance and replacement.

[0016] Preferably, the width limiting component includes a connecting frame one, an adjusting sleeve one fixedly installed at the outer edge of the connecting frame one, an adjusting sleeve two slidably connected at the outer edge of the connecting frame one, a knob one threadedly connected at the outer edge of the adjusting sleeve two, the knob one passing through the adjusting sleeve two and abutting against the connecting frame one, and a limiting rod fixedly installed at the end of the adjusting sleeve two away from the connecting frame one.

[0017] Through the above technical solution, by sliding the adjustment sleeve 2 of the width limiting component along the connecting frame 1 and locking it with the knob 1, the spacing of the limiting rod can be adjusted to limit the width direction deviation of the paper on the conveyor belt, so that the paper is conveyed along the central path to the folding position for folding.

[0018] Preferably, the blocking assembly includes a second connecting frame, with an installation hole at the outer edge of the second connecting frame, a limit sleeve slidably connected to the outer edge of the second connecting frame, a second knob threadedly connected to the outer edge of the limit sleeve, the second knob passing through the limit sleeve and abutting against the second connecting frame, a stop strip fixedly installed at the end of the limit sleeve away from the second connecting frame, and a reinforcing block fixedly installed at the connection between the fixing frame and the positioning plate.

[0019] The above technical solution uses the baffle of the blocking component to position the folding position of the paper, so that each sheet of paper is folded in the same position, avoiding folding deviation caused by inconsistent paper feeding length, and the reinforcing block enhances the connection strength between the fixing frame and the positioning plate.

[0020] Compared with the prior art, this utility model provides a folding mechanism for printing presses, which has the following advantages:

[0021] 1. The folding mechanism of this printing press, through the design of the lifting column and the transmission box, and the sliding connection between the two, facilitates the directional guidance of the lifting column, avoiding easy shaking. This allows the lifting column to drive the folding rod to rise and fall along a preset trajectory, preventing folding deviation caused by shaking. Furthermore, through the design of multiple sets of equally spaced mounting slots for the folding rod, when installing the folding rod, the position of the folding rod on the card holder can be adjusted according to the length of different papers, which can easily cover the folding needs of different sizes and thicknesses of paper, improving overall versatility.

[0022] 2. The folding mechanism of this printing press uses a width limiting component to slide along the connecting frame and lock with a knob. The spacing of the limiting rods can be adjusted to limit the width deviation of the paper on the conveyor belt, so that the paper is conveyed along the center path to the folding position for folding. The blocking component positions the folding position of the paper, so that each sheet of paper is folded in the same position, avoiding folding deviation caused by inconsistent paper conveying length. The reinforcing block enhances the connection strength between the fixing frame and the positioning plate. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: As Figures 1-8As shown, the present invention provides a folding mechanism for a printing machine, including a conveyor belt 1, a mounting base 2, a connecting plate 3, a width limiting component 9, and a blocking component 10. A fixing frame 4 is fixedly installed at the end of the connecting plate 3 away from the mounting base 2. A positioning plate 5 is fixedly installed at the end of the fixing frame 4 away from the connecting plate 3. A transmission component 7 is fixedly installed at the end of the positioning plate 5 away from the fixing frame 4. A connecting component 8 is fixedly installed at the end of the transmission component 7 away from the positioning plate 5. A through groove 11 is provided at the inner edge of the conveyor belt 1, and the through groove 11 is located directly below the connecting component 8.

[0034] The transmission assembly 7 includes a transmission box 701. A servo motor 702 is fixedly installed on the outer edge of the transmission box 701. A connecting shaft 703 is fixedly installed on the output end of the servo motor 702. A transmission disk 704 is fixedly installed on the other end of the connecting shaft 703 away from the servo motor 702. A connecting sleeve 705 is fixedly installed on the other end of the transmission disk 704 away from the connecting shaft 703.

[0035] The connecting component 8 includes a lifting column 801. A retainer 802 is fixedly installed at the end of the lifting column 801 away from the transmission component 7. A hinge rod 804 is engaged at the end of the retainer 802 away from the lifting column 801.

[0036] Specifically, a connecting rod 706 is fixedly installed at the end of the connecting sleeve 705 away from the transmission disk 704, and a connecting sleeve 707 is fixedly installed at the end of the connecting rod 706 away from the connecting sleeve 705. The connecting sleeve 707 and the lifting column 801 are fixedly installed. The advantage is that, through the cooperation of the connecting sleeve 705, the connecting rod 706 and the connecting sleeve 707, the rotational power of the servo motor 702 is converted into the linear lifting motion of the lifting column 801, so that the folding rod 804 moves up and down. When the printed paper reaches below the folding rod 804, the folding rod 804 folds the paper.

[0037] Specifically, the lifting column 801 and the transmission box 701 are slidably connected. The lifting column 801 passes through the transmission box 701 and extends to its inner edge. The advantage is that the design of the lifting column 801 and the transmission box 701, combined with their slidable connection, facilitates the directional guidance of the lifting column 801, avoids easy shaking, and allows the lifting column 801 to drive the folding rod 804 to rise and fall along a preset trajectory, avoiding folding deviation caused by shaking.

[0038] Specifically, the folding rod 804 has a mounting groove 805 on its outer edge. Multiple mounting grooves 805 are equally spaced. The advantage is that, through the design of multiple equally spaced mounting grooves 805 on the folding rod 804, when the folding rod 804 is installed, the position of the folding rod 804 on the card holder 802 can be adjusted according to the length of different papers, which is convenient for covering the folding needs of papers of different sizes and thicknesses and improves the overall versatility.

[0039] Example 2: Figures 2-8 As shown, this is an improvement on the previous embodiment.

[0040] Specifically, the sleeve 802 has a slot 806 at one end near the folding rod 804, and a limit bolt 803 is threadedly connected to the outer edge of the sleeve 802. The advantage is that, through the design of the slot 806, the slot 806 of the sleeve 802 positions the folding rod 804, and locks it with the limit bolt 803, so as to realize the fixation and quick disassembly of the folding rod 804, which not only prevents the folding rod 804 from loosening or shifting during folding, but also facilitates later maintenance and replacement.

[0041] Specifically, the width limiting component 9 includes a connecting frame 901, an adjusting sleeve 902 fixedly installed on the outer edge of the connecting frame 901, an adjusting sleeve 903 slidably connected to the outer edge of the connecting frame 901, and a knob 904 threadedly connected to the outer edge of the adjusting sleeve 903. The knob 904 passes through the adjusting sleeve 903 and abuts against the connecting frame 901. A limiting rod 905 is fixedly installed at the end of the adjusting sleeve 903 away from the connecting frame 901. The advantage is that by sliding the adjusting sleeve 903 of the width limiting component 9 along the connecting frame 901 and locking it with the knob 904, the spacing of the limiting rod 905 can be adjusted, limiting the width direction deviation of the paper on the conveyor belt 1, so that the paper is conveyed along the center path to the folding position for folding.

[0042] Specifically, the blocking component 10 includes a second connecting frame 1001. The second connecting frame 1001 has an installation hole 1002 at its outer edge. A limit sleeve 1003 is slidably connected to the outer edge of the second connecting frame 1001. A second knob 1004 is threadedly connected to the outer edge of the limit sleeve 1003. The second knob 1004 passes through the limit sleeve 1003 and abuts against the second connecting frame 1001. A stop strip 1005 is fixedly installed at the end of the limit sleeve 1003 away from the second connecting frame 1001. A reinforcing block 6 is fixedly installed at the connection between the fixing frame 4 and the positioning plate 5. The advantage is that the stop strip 1005 of the blocking component 10 positions the folding position of the paper, so that each sheet of paper is folded at the same position, avoiding folding deviation caused by inconsistent paper feeding length. In addition, the reinforcing block 6 enhances the connection strength between the fixing frame 4 and the positioning plate 5.

[0043] Working Principle: During use, the rotational power of the servo motor 702 is converted into the linear lifting motion of the lifting column 801 through the cooperation of connecting sleeve 1 705, connecting rod 706, and connecting sleeve 2 707. This causes the folding rod 804 to move up and down. When the printed paper reaches below the folding rod 804, the folding rod 804 folds the paper. The design of multiple equally spaced mounting slots 805 on the folding rod 804 allows for adjustment of its position on the card holder 802 according to the length of different papers, facilitating the folding needs of different sizes and thicknesses of paper and improving overall versatility. To meet the folding requirements of thick and thin paper and improve overall versatility, the design of the slot 806 in the card sleeve 802 positions the folding rod 804, which is locked with the limit bolt 803 to achieve the fixation and quick disassembly of the folding rod 804. This prevents the folding rod 804 from loosening or shifting during folding and facilitates later maintenance and replacement. The adjustment sleeve 903 of the width limiting component 9 slides along the connecting frame 901 and is locked with the knob 904. The spacing of the limit rod 905 can be adjusted to limit the width direction deviation of the paper on the conveyor belt 1, so that the paper is conveyed along the central path to the folding position for folding. The baffle 1005 of the blocking component 10 positions the folding position of the paper, so that each sheet of paper is folded in the same position, avoiding folding deviation caused by inconsistent paper conveying length. In addition, the reinforcing block 6 enhances the connection strength between the fixing frame 4 and the positioning plate 5.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
