Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a paper cutting machine for advertising printing. Background Technology

[0002] A paper cutting machine for advertising printing is a professional piece of equipment used in the advertising printing industry. In the cutting process, the paper printed with advertisements is wound into a roll. During printing, the roll smoothly releases the advertising material, which is then guided by guide rollers and continuously fed to the designated cutting area below the cutter. This allows the cutter to precisely cut the advertising material according to preset dimensions and shapes, resulting in finished advertising paper products that meet usage requirements. In advertising printing, various types of advertising paper differ in thickness, toughness, and elasticity due to their inherent physical properties. However, the currently used... The rolls used are often of fixed specifications and lack the ability to flexibly adjust tension and spacing. This makes it difficult to match with all paper characteristics, and thus it is impossible to optimize the friction and stress between the paper and the roll as needed, making it difficult to achieve the ideal state. Due to the limitation of the fixed roll specifications, in the unwinding process, for thicker and harder papers, the roll spacing is often too small because it cannot be increased as needed, causing the paper to be frequently obstructed and jammed during unwinding. For thin and flexible papers, if the applied tension cannot be reduced as needed, excessive tension can easily cause the paper to break due to overstretching during unwinding. Utility Model Content

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0030] Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a paper cutting machine for advertising printing. The paper cutting machine for advertising printing includes a main component 100 and an adjustment component 200. The two components work together to adjust the roll spacing and tension according to the characteristics of the advertising paper, thereby optimizing the situation, avoiding unwinding failures, and ensuring smooth unwinding.

[0031] The main component 100 includes a cutting machine body 101, a cutting blade 102 is provided on the cutting machine body 101, and a roll 103 is fixed on one side of the cutting machine body 101.

[0032] When it is necessary to cut the advertising paper, the advertising paper is first wound onto the roll 103, and then the advertising paper is connected to the cutting machine body 101. The cutting machine body 101 is then started. During printing, the roll 103 smoothly releases the rolled advertising material. The advertising material is then guided by the guide rollers on the cutting machine body 101 and continuously conveyed to the designated cutting area below the cutter 102. The cutter 102 is then used to cut it. After cutting, the material is discharged by the cutting machine body 101. The cutting machine body 101 is existing technology and will not be described in detail here.

[0033] An adjustment assembly 200 is disposed on the drum 103 and includes an adjustment member 201. The adjustment member 201 includes an expansion plate 2011, which is located on the drum 103. A movable column 2012 is fixed to the bottom of the expansion plate 2011, and a drive bar 2013 is fixed to the bottom of the movable column 2012. A drive disc 2014 is sleeved on the outside of the drive bar 2013, and the drive bar 2013 and the drive disc 2014 are movably connected.

[0034] When it is necessary to adjust the tension of the advertising paper, the drive disk 2014 is rotated. The drive disk 2014 has a drive groove corresponding to the drive bar 2013. When the drive disk 2014 rotates, it can drive the drive groove to rotate and squeeze the drive bar 2013 to move. At this time, the movement of the drive bar 2013 can drive the movement column 2012 to move. The movement of the movement column 2012 can drive the expansion plate 2011 to move. By moving the expansion plate 2011 to different positions, the winding tension of the advertising paper can be adjusted. Example

[0035] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the adjustment assembly 200 also includes a movable component 202, which includes a support frame 2021. The support frame 2021 is rotatably connected to one side of the drive disk 2014 via a bearing.

[0037] The movable column 2012 is inserted into one side of the support frame 2021. The movable column 2012 and the support frame 2021 are movably connected. The support frame 2021 can be used to movably connect the drive disk 2014 and the movable column 2012 to prevent them from shifting.

[0038] Specifically, a movable cover 2022 is movably connected to one side of the support frame 2021, and a movable rod 2023 is inserted into one side of the movable cover 2022. The movable cover 2022 and the movable rod 2023 are movably connected.

[0039] When it is necessary to roll up paper of different widths, the movable cover 2022 can be moved to different positions within the support frame 2021 to accommodate paper of different widths. The movable rod 2023 can support the adjusting plate 2024 to prevent the adjusting plate 2024 from shifting.

[0040] Specifically, an adjustment plate 2024 is fixed to the top of the movable rod 2023, and a movable plate 2025 is fixed to one side of the adjustment plate 2024. The movable plate 2025 is inserted into one side of the expansion plate 2011, and the movable plate 2025 and the expansion plate 2011 are movably connected.

[0041] When the expansion plate 2011 expands, it can drive the movable plate 2025 to move. At this time, the movement of the movable plate 2025 can drive the adjustment plate 2024 to move, so that the adjustment plate 2024 and the expansion plate 2011 can move synchronously to adjust the winding tension. By moving the adjustment plate 2024 to a different distance from the expansion plate 2011, paper of different widths can be wound. The movable plate 2025 can support the adjustment plate 2024 to prevent the adjustment plate 2024 from deviating during movement.

[0042] Specifically, a first spring 2026 is fixed to the inner wall of the movable plate 2025. One end of the first spring 2026 is fixed to the inner wall of the expansion plate 2011. A support strip 2027 is fixed to the inner wall of the expansion plate 2011. The support strip 2027 is inserted into one side of the movable plate 2025, and the support strip 2027 and the movable plate 2025 are movably connected.

[0043] When the adjusting plate 2024 moves, causing the movable plate 2025 to move, the movement of the movable plate 2025 applies a pulling force to the first spring 2026. At the same time, the movable plate 2025 moves on the support bar 2027. The support bar 2027 supports the movable plate 2025 and prevents it from shifting. The rebound force of the first spring 2026 can drive the movable plate 2025 back to its original position, thereby allowing the adjusting plate 2024 to return to its original position for the next use.

[0044] Specifically, the adjustment component 200 also includes a movable component 203, which includes a plug rod 2031. The plug rod 2031 is inserted into one side of the drive disk 2014 and is movably connected to the drive disk 2014. A locking block 2032 is fixed on one side of the plug rod 2031.

[0045] Insert rods 2031 are inserted into one side of support frame 2021 and movable cover 2022 respectively. Insert rods 2031 are movably connected to both. A locking block is fixed on the insert rod 2031. A slot corresponding to the locking block is opened on the drive disk 2014. The locking block is slidably connected to the slot. By rotating the insert rod 2031, the locking block can be rotated to squeeze the slot, thereby driving the drive disk 2014 to rotate.

[0046] Specifically, a limit block 2033 is provided inside the insertion rod 2031, and a hinge rod 2034 is provided at the bottom of the limit block 2033. The limit block 2033 and the hinge rod 2034 are hinged together.

[0047] A limiting groove corresponding to the limiting block 2033 is provided on the inner wall of the movable cover 2022. After the drive disk 2014 is rotated to the designated position, in order to prevent the drive disk 2014 from rotating on its own, the limiting block 2033 can be engaged with the limiting groove to limit the drive disk 2014. The limiting block 2033 can also be engaged with the limiting groove to limit the movable cover 2022 to prevent the movable cover 2022 from moving on its own. When it is necessary to separate the limiting block 2033 from the limiting groove, the hinge rod 2034 is pressed to make it move the limiting block 2033. The movement of the limiting block 2033 and the separation from the limiting groove can simultaneously release the limiting of the drive disk 2014 and the movable cover 2022. Then, the winding tension and the width of the wound paper can be adjusted at the same time. Example

[0048] Reference Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, a rotating column 2035 is inserted into one side of the hinge rod 2034. The rotating column 2035 is inserted into the inner wall of the insert rod 2031. The rotating column 2035 and the insert rod 2031 are rotatably connected by a rotating shaft. A torsion spring 2036 is fixed to one side of the rotating column 2035. One end of the torsion spring 2036 is fixed to the inner wall of the insert rod 2031.

[0050] The hinge rod 2034 can be supported by the rotating column 2035 to prevent it from shifting during movement. When the hinge rod 2034 moves and causes the limiting block 2033 to separate from the limiting groove, a torsional force can be applied to the torsion spring 2036. The force of the torsion spring 2036 can drive the hinge rod 2034 back to its original position, so that the limiting block 2033 returns to its original position and re-engages with the limiting groove.

[0051] Specifically, a compression sleeve 2037 is provided on one side of the hinge rod 2034, and a pressing rod 2038 is fixed on one side of the compression sleeve 2037.

[0052] The inner wall of the extrusion sleeve 2037 is set as an inclined surface. The pressing rod 2038 is inserted into one side of the insertion rod 2031. The pressing rod 2038 and the insertion rod 2031 are movably connected. By pressing the pressing rod 2038, the extrusion sleeve 2037 can be driven to extrude the hinge rod 2034, thereby causing the hinge rod 2034 to move and drive the limiting block 2033 to separate from the limiting groove.

[0053] Specifically, a second spring 2039 is fixed to one side of the compression sleeve 2037, and one end of the second spring 2039 is fixed to one side of the pressing rod 2038.

[0054] A compression plate is sleeved on the outside of the pressing rod 2038. When the pressing rod 2038 is pressed, the compression plate can move to apply a compressive force to the second spring 2039. At this time, the compression sleeve 2037 can move to compress the hinge rod 2034. When the pressing rod 2038 is released, the force of the second spring 2039 can drive the pressing rod 2038 back to its original position, thereby allowing the compression sleeve 2037 to return to its original position and release the compression on the hinge rod 2034.

[0055] In use, first press the pressing rod 2038. As the pressing rod 2038 moves, it moves the extrusion plate, applying a compressive force to the second spring 2039. Simultaneously, the movement of the pressing rod 2038 causes the extrusion sleeve 2037 to move, compressing the hinge rod 2034. The movement of the hinge rod 2034 causes the limiting block 2033 to separate from the limiting groove. At the same time, the movement of the hinge rod 2034 applies a torsional force to the torsion spring 2036. After the limiting block 2033 separates from the limiting groove, the limiting of the insertion rod 2031 is released. Then, the insertion rod 2031 is rotated. The rotation of the insertion rod 2031 causes the locking block to rotate, compressing the locking groove, which in turn causes the drive disc 2014 to rotate. The rotation of the drive disc 2014 causes the drive groove to rotate, compressing the drive bar 2013 and causing it to move. The movement of the drive bar 2013 then causes the moving column 2012 to move. The movement of the moving column 2012... The expansion plate 2011 can be moved, and the movement of the expansion plate 2011 will also drive the movement of the movable plate 2025. At this time, the movement of the movable plate 2025 can drive the movement of the adjusting plate 2024, so that the adjusting plate 2024 and the expansion plate 2011 can move synchronously to adjust the winding tension. At the same time, the limitation on the movable cover 2022 can be released. Then, the movable cover 2022 can be moved to different positions within the support frame 2021, which can drive the adjusting plate 2024 to move to adapt to paper of different widths. When the adjustment plate 2024 moves, it drives the movable plate 2025 to move. At this time, the movement of the movable plate 2025 can apply a pulling force to the first spring 2026. Simultaneously, the movable plate 2025 will move on the support bar 2027. The support bar 2027 can support the movable plate 2025 and prevent the movable plate 2025 from shifting.

[0056] After adjustment, release the pressing rod 2038. The force of the second spring 2039 returning the pressing rod 2038 to its original position will cause the compression sleeve 2037 to return to its original position and release the compression on the hinge rod 2034. Then, the force of the torsion spring 2036 rotating will cause the hinge rod 2034 to return to its original position, causing the limiting block 2033 to return to its original position and re-engage with the limiting groove. This will simultaneously limit the drive disc 2014 and the movable cover 2022, preventing them from moving on their own.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
