Description
Technical Field
[0001] This utility model belongs to the technical field of printing processing equipment, and in particular relates to a waste paper roll cutting mechanism for printing production. Background Technology
[0002] Printing paper is primarily produced by printing presses, which typically consist of plate mounting, inking, printing, and paper feeding mechanisms. During printing, the paper roll is conveyed by a paper conveying mechanism, which also carries spare paper rolls. During operation, the paper conveying mechanism automatically senses the amount of paper roll in use using infrared sensors. When the amount of printing paper on the roll is low, to prevent interruption during printing, the remaining amount of paper roll is cut. Then, the printing paper from the spare paper roll (with double-sided tape) is attached to the currently used roll for use. The remaining paper roll is then replaced with a complete roll for further use. Multiple remaining paper rolls are collectively referred to as waste paper rolls in the printing plant. To avoid waste, these waste paper rolls are usually mounted on a cutting mechanism to cut the remaining material into different sizes of paper for use.
[0003] As described above, after waste paper rolls are collected, they need to be frequently changed on the cutting machine for processing. This requires the cutting machine to have a convenient roll changing component. Considering that the loading and unloading of existing waste paper rolls is mostly done manually, it affects the work process and is labor-intensive. In addition, regarding the cutting of paper on the waste paper rolls, in order to cut it into paper that meets the usage requirements, it is usually first cut into strips horizontally, and then cut vertically. Existing cutting equipment needs to complete the above processing work in steps. The main reason for this is that the paper cutting point lacks a positioning mechanism. That is to say, after the paper is cut vertically, its cutting end cannot be conveniently output. This also prevents the paper from being continuously fed for multiple cuts, making the production process relatively cumbersome, affecting the work process, and failing to meet the usage requirements. Utility Model Content
[0004] This utility model addresses the technical problems existing in the above-mentioned waste paper roll cutting process by proposing a waste paper roll cutting mechanism with reasonable design, simple structure, convenient processing, and the ability to conveniently feed waste paper rolls, reducing labor intensity. At the same time, it positions the material at the longitudinal cutting position, ensuring the smooth progress of the cutting work and avoiding material deviation. Furthermore, it allows the material to be unloaded after longitudinal cutting, so that subsequent materials can be cut smoothly, thus fully meeting the usage requirements.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0015] Examples, such as Figures 1-5As shown, a waste paper roll 25 cutting mechanism for printing production includes a cutting mechanism body, which includes a frame 1. A material loading mechanism is provided on one side of the frame 1. The material loading mechanism includes a frame assembly 2. A lifting mechanism 3 is provided on one side of the frame assembly 2. The lifting mechanism 3 replaces manual labor in lifting the waste paper roll 25 toward the frame assembly 2, eliminating the need for manual workpiece handling and greatly reducing operational difficulty. At the same time, the frame assembly 2 can smoothly limit the waste paper roll 25, ensuring the smooth flow of subsequent material output. Multiple sets of conveyor rollers 4 are arranged side by side above the frame 1 to ensure the smooth flow of paper material and facilitate cutting. A support rod 41 is provided above the middle conveyor roller 4. Multiple rotatable and adjustable cross-cutting blades 42 are evenly distributed on the support rod 41. The cross-cutting blades 42 can not only be rotated and adjusted on the support rod 41 to adjust their cutting depth, but also can be adjusted on the support rod 41. The rod 41 is adjusted longitudinally to achieve cutting of different sizes. Of course, locking is achieved by locking screws. The paper during the conveying process can be cut laterally by the cross-cutting blade 42. A gantry-shaped support frame 5 is set above the frame 1 at one end of the conveying roller 4. The support frame 5 is equipped with a longitudinal cutting mechanism 6 that integrates pressure positioning and longitudinal cutting functions. The longitudinal cutting mechanism 6 cooperates with the cross-cutting blade 42 to achieve transverse and longitudinal cutting of the conveyed paper material, ensuring that the material can be cut into appropriate sizes, so that the paper material can be put into subsequent use, saving production materials. A conveying and positioning mechanism 7 that integrates positioning and conveying functions is set on one side of the support frame 5. It combines positioning and conveying functions, which can not only convey the paper material, but also position it during cutting to prevent it from deviating. This greatly improves the functionality of the equipment and ensures the smoothness of the cutting process, meeting the usage requirements. In the above process: the lifting mechanism 3 replaces manual labor in lifting the waste paper roll 25 towards the frame assembly 2, eliminating the need for manual handling and greatly reducing operational difficulty. Simultaneously, the frame assembly 2 effectively limits the waste paper roll 25, ensuring smooth material output. The cross-cutting blade 42 and longitudinal cutting mechanism 6 enable cross- and longitudinal cutting of the conveyed paper material, ensuring it is cut to the appropriate size for subsequent use, thus saving production resources. The conveying and positioning mechanism 7 integrates positioning and conveying... The feeding function not only transports the paper material but also positions it during cutting to prevent deviation, greatly improving the functionality of the equipment and ensuring smooth cutting processes to meet usage requirements. This device is rationally designed, simple in structure, and easy to process, enabling convenient feeding of waste paper rolls 25, reducing labor intensity. Simultaneously, it positions the material at the longitudinal cutting position, ensuring smooth cutting and preventing material deviation. Furthermore, it allows for material removal after longitudinal cutting, facilitating subsequent cutting and fully meeting usage needs.
[0016] To accommodate frequent paper roll changes and reduce operational difficulty, the frame assembly 2 includes a mounting plate 21 connected to the frame body 1. A C-shaped mounting sleeve 22 is provided on one side of the mounting plate 21. The notch in the mounting sleeve 22 facilitates the entry of the end of the paper roll 25 and its engagement with the positioning sleeve 24. A drive motor 23 is located on one side of the mounting sleeve 22. A U-shaped groove 211 is formed within the mounting plate 21, corresponding to the output end of the drive motor 23. The U-shaped groove 211 facilitates the entry of the rotating sleeve 26 of the paper roll 25. The output end of the drive motor 23 is provided with a concave positioning sleeve 24. The paper roll 25 is placed within the mounting plate 21, and the end of the paper roll 25 is fitted with a rotating sleeve 26. The rotating sleeve 26 can rotate relative to the end of the paper roll 25. When the rotating sleeve 26 is placed within the mounting plate 21, the paper roll 25... The end of the rotating sleeve 26 is connected to the positioning sleeve 24, which controls the operation of the drive motor 23. Its rotation can drive the waste paper roll 25 to rotate, completing the limit and ensuring the convenient discharge of paper material. The end of the waste paper roll 25 located on one side of the rotating sleeve 26 is designed with a key shape and is adapted to and engaged with the positioning sleeve 24. That is to say, the lifting mechanism 3 lifts the waste paper roll 25 until the waste paper roll 25 corresponds to the mounting plate 21, and pushes the waste paper roll 25 into the mounting plate 21. The rotating sleeve 26 corresponds to its U-shaped groove 211, and the end of the waste paper roll 25 is engaged in the positioning sleeve 24, ensuring convenient transmission of driving power. Of course, in order to ensure the stability of the connection, a locking screw can be set on the outside of the positioning sleeve 24 to limit it together with the end of the waste paper roll 25, reducing the difficulty of operation and making the roller changing process more convenient and improving the work process.
[0017] To replace manual lifting of the waste paper roll 25, the lifting mechanism 3 includes a frame 31, a lifting drive cylinder 32 mounted on top of the frame 31, a vertical slide bar 33 inside the frame 31, a vertical slide block 34 mounted on the vertical slide bar 33, and a carrier plate 35 on one side of the vertical slide block 34. The carrier plate 35 has an arc-shaped groove 351. Specifically, the waste paper roll 25 is manually pushed to the position of the lifting mechanism 3, the lifting drive cylinder 32 is extended, and the carrier plate 35 is adjusted to be positioned below both ends of the waste paper roll 25. The waste paper roll 25 is aligned with the carrier plate 35 of the lifting mechanism 3 at its end, especially at the arc groove 351. Then, the lifting drive cylinder 32 is controlled to retract, driving the carrier plate 35 to rise until the carrier plate 35 contacts both ends of the waste paper roll 25, and the arc groove 351 limits the two ends of the waste paper roll 25. Then, the lifting drive cylinder 32 is controlled to run, driving the waste paper roll 25 to rise until it is parallel to the mounting plate 21 of the frame assembly 2, pushing the waste paper roll 25 into the frame assembly 2, waiting for subsequent paper feeding to meet the usage requirements.
[0018] To complete the longitudinal cutting of the workpiece, the longitudinal cutting mechanism 6 includes a limiting slide rod 61 set inside the support frame 5, a lifting plate 62 set on the limiting slide rod 61, a longitudinal cutting drive cylinder 63 set above the support frame 5 and connected to the lifting seat, a bearing plate 64 set inside the support frame 5 below the lifting seat, a pressure plate 65 set below the lifting plate 62, a connecting plate 66 set below the lifting seat on one side of the pressure plate 65, and a longitudinal cutting blade 67 set below the connecting plate 66. Specifically, the paper material that has been transversely cut is conveyed to the conveying station by the conveying roller 4. In the positioning mechanism 7, the conveying and positioning mechanism 7 conveys the material. When the material outputs to a suitable length, the longitudinal cutting drive cylinder 63 is controlled to extend, causing it to drive the lifting plate 62 and the longitudinal cutting blade 67 to move vertically downwards and longitudinally cut the conveyed paper. During the descent, the pressure plate 65 also cooperates with the bearing plate 64 to press the conveyed material, assisting the conveying and positioning mechanism 7 in limiting the workpiece. Of course, this design can also flatten the conveyed paper material to ensure the smooth progress of subsequent cutting work and improve the work process.
[0019] To position and clamp the incoming paper material, preventing it from shifting, and to guide the paper material after cutting, the conveying and positioning mechanism 7 includes a support plate 71 connected to the support frame 5 and designed with an obtuse angle. A fixed plate 72 is located below the support plate 71, and a concave frame 73 is located below the fixed plate 72. A positioning rod 74 is located above the concave frame 73, penetrating the fixed plate 72. A shock-absorbing spring 75 is sleeved on the outside of the positioning rod 74, located between the fixed plate 72 and the concave frame 73. A drive roller 76 is located inside the concave frame 73. A motor 77 is installed on one side of the 3, and its output end is rotatably connected to the end of the drive roller 76. An auxiliary roller 78 is installed on the frame 1 located below the conveying and positioning mechanism 7. Specifically, for the concave frame 73, it is connected to the positioning rod 74 and can be adjusted vertically relative to the support plate 71. When the equipment is stationary, the drive roller 76 is at the lowest position and is in contact with the outer circumferential surface of the auxiliary roller 78. The paper material is discharged from between the two. During use, the paper material can be output from between the two. When the paper needs to be cut. The material remaining between the drive roller 76 and the auxiliary roller 78 is currently stationary, meaning the motor 77 is not controlled to run. When the paper is longitudinally cut, the motor 77 is controlled to run, causing its output end to rotate. This rotation acts on the synchronous belt connecting the ends of the drive roller 76 and the motor 77, thus transmitting the driving power. The rotation of the drive roller 76 then drives the paper at that point to continue being conveyed. This process repeats, and the paper, after being conveyed and longitudinally cut, is cut by the longitudinal cutting mechanism 6 and then collected and discharged externally for easy collection. This design utilizes the established drive roller 76, which can position the conveyed workpiece. Its lifting mechanism can adapt to materials of different thicknesses, ensuring the stability of the material at that location. Furthermore, the rotation of the drive roller 76 also conveys the material, ensuring continuity during material transport and meeting usage requirements. It should be further noted that a cylinder can be installed above the support plate 71 to freely adjust the position of the concave frame 73. This method can replace the aforementioned adaptive adjustment, is convenient, and provides convenient conditions for material changing.
[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
