[0002] A printing press is a mechanical device mainly used to print text and images onto media such as paper, cloth, plastic, and metal. The working principle of a printing press is to accurately transfer ink onto the substrate through the coordinated action of the printing plate, ink, and pressure system to complete the printing process. The printing press cutter is a tool used to cut paper or other printed materials during the printing process. Its main function is to accurately cut the printed material to the required size to ensure the quality and precision of the finished product.

[0003] Chinese Utility Model Patent Publication No. CN 218084681 U discloses a printing device with a film cutting function. This device starts a conveyor belt, and when the desired printing length is reached, a servo motor is activated again, causing a hot blade to press down and cut the plastic film into a cutting groove, facilitating subsequent printing. The ability to raise and lower the hot blade during printing greatly simplifies the placement of the plastic film and makes cutting easier. However, this printing device uses only a single cutting blade body, resulting in low cutting efficiency and operational flexibility. Furthermore, it lacks a quick-installation structure for the cutting blade body, making maintenance difficult after prolonged use. This reduces its practicality and hinders its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cutting blade mounting structure for printing, which can effectively solve the problems of the prior art that only uses a single cutting blade body for cutting, resulting in low cutting efficiency and operational flexibility, and the lack of a quick installation structure for the cutting blade body, making it inconvenient to repair after long-term use, thus having low practicality and being difficult to promote and use.

[0005] The technical solution adopted by this utility model is: a printing cutter mounting structure, including a support component and a mounting frame.

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.

[0029] Example 1: As Figure 1-6 As shown, the present invention provides a printing cutter mounting structure, including a support component 1 and a mounting frame 2. A roller 3 is rotatably mounted on the outer side of the mounting frame 2. A conveying component 4, a limiting component 5, a control component 6, a second conveying component 7, and a slide bar 8 are fixedly mounted on the side of the support component 1 near the mounting frame 2.

A fixing block 15 is fixedly mounted on the top of the crossbar 9. A guide groove 16, a through hole 17, and a slot 18 are opened on the side of the fixing block 15 near the cutter body 12. A buckle 19 is fixedly mounted on the side of the cutter body 12 near the crossbar 9. A fixing block 22 is fixedly mounted on the side of the support component 1 near the mounting frame 2. A drive component 30 is fixedly mounted inside the support component 1.

[0030] Specifically, a positioning groove 23 and a through hole 24 are provided on the outer side of the fixing block 22. A fixing block 3 25 is provided at the top of the fixing block 22. A cutting groove 26 is provided on the side of the fixing block 3 25 away from the fixing block 22.

Two identical cutting blade bodies 12 are provided, symmetrically distributed about the center line of the crossbar 9. The bolt 20 passes through through hole one 14 and through hole two 17, with the same hole diameter. The advantage is that after quickly positioning the cutting blade body 12, the operator can then insert the bolt 20 through through hole one 14 and through hole two 17, and then thread the nut 21 onto the bolt 20, achieving a quick connection between the two cutting blade bodies 12. This design of two cutting blade bodies 12 eliminates the need for frequent blade changes or direction adjustments during use, improving cutting efficiency and operational flexibility, making it highly practical.

[0035] Specifically, the drive assembly 30 includes a motor 3001, a worm gear 3002, a mounting base 3003, a rotating shaft 3004, a worm 3005, a rotating plate 3006, a connecting rod 3007, a connecting piece 3008, and a slider 3009.

The rotating shaft 3004 is rotatably installed on the outer side of the mounting base 3003. The worm 3005 and the rotating plate 3006 are fixedly installed on the outer side of the rotating shaft 3004. The connecting rod 3007 is rotatably installed on the side of the rotating plate 3006 away from the rotating shaft 3004. The connecting piece 3008 and the slider 3009 are fixedly installed at the end of the crossbar 9 near the slide bar 8. The worm gear 3002 and the worm 3005 are meshed together, and the connecting piece 3008 and the connecting rod 3007 are rotatably connected. The advantage is that when the operator starts the motor 3001, the output end of the motor 3001 drives the rotating shaft 3004 to rotate through the cooperation of the worm gear 3002 and the worm 3005. The rotation of the rotating shaft 3004 drives the rotating plate 3006 to rotate, thereby driving the crossbar 9 to move up and down, which can realize the rapid cutting of plastic film and has high practicality.

[0036] Specifically, slider 3009 and slide rod 8 are slidably connected, and the cross-section of rotating plate 3006 is shaped like a "cam". The advantage is that, during the cutting of plastic film, the cooperation between slider 3009 and slide rod 8 guides the crossbar 9, improving overall stability and making it highly practical.

[0037] Working principle: During installation, the operator inserts the positioning block 27 into the positioning groove 23, and then extends the limiting rod 29 through the through hole 28 to the through hole 24, which enables the quick installation of the fixing block 25. After long-term use, it is convenient to clean the inside of the cutting groove 26, which is highly practical. Then, the operator inserts the cutting blade body 12 into the guide groove 10 and the guide groove 2 16, and inserts the insert block 11 into the insertion hole 13, which enables the quick positioning of the cutting blade body 12, which is convenient for subsequent limiting. Through the cooperation of the buckle 19 and the slot 18, during the quick positioning of the cutting blade body 12, when the buckle 19 contacts the fixing block 15, the buckle 19 deforms. When the insert block 11 is completely inserted into the insertion hole 13, the buckle 19 returns to its original shape, so that the buckle 19 is inserted into the slot 18, which enables the quick limiting of the cutting blade body 12. After prolonged use, maintenance is convenient. After quickly limiting the cutting blade body 12, the operator inserts bolt 20 through through hole 14 and through hole 27, and then threads nut 21 onto bolt 20, achieving a quick connection between the two cutting blade bodies 12. The design of two cutting blade bodies 12 eliminates the need for frequent blade replacement or direction adjustment during use, improving cutting efficiency and operational flexibility, making it highly practical. In use, the operator first connects the external power supply and starts motor 3001. The output end of motor 3001 drives the rotating shaft 3004 to rotate through the cooperation of worm gear 3002 and worm 3005. The rotation of rotating shaft 3004 drives rotating plate 3006 to rotate, thereby moving crossbar 9 up and down, enabling rapid cutting of plastic film, making it highly practical. When cutting plastic film, the cooperation of slider 3009 and slider 8 guides crossbar 9, improving overall stability, making it highly practical.
