Description

Technical Field

[0001] This utility model relates to the field of papermaking and printing technology, and in particular to an anti-sticking device for printing paper production rollers. Background Technology

[0002] Printing rollers are an indispensable key component in the production of printing paper. They are generally composed of a metal core and an outer rubber layer, possessing good elasticity, abrasion resistance, and chemical stability. During production, they are used to transfer printing media such as inks and coatings. Through cooperation with the printing plate and paper, they transfer patterns and text onto the paper surface, ensuring the clarity, color uniformity, and integrity of the print. They also provide support and guidance during paper transport, using surface friction to ensure the paper passes smoothly through each production stage, preventing wrinkles and ensuring the continuity and stability of printing paper production. However, after prolonged use, inks and other substances can dry and solidify on the roller's surface. These solidified substances can easily cause adhesion between the roller and the paper. This can not only tear the paper during separation, damaging product quality, but also hinder smooth paper transport, disrupt the production rhythm, and reduce the continuity and stability of printing paper production.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] Example 1

[0030] Reference Figures 1-7 This is the first embodiment of the present invention, which provides an anti-sticking device for printing paper production rollers. The anti-sticking device includes a main component and a scraping component. The two components work together to scrape away surface substances from the rollers after prolonged use, restoring them to a clean state, preventing adhesion, ensuring stable paper feeding and production, and improving efficiency.

[0031] The main component 100 includes a rewinder 101, on which a rubber roller 102 is provided, and a base 103 is fixed at the bottom of the rewinder 101.

[0032] The rewinder 101 is mainly used to rewind large rolls of raw paper produced by the paper machine or pre-processed paper rolls into finished paper rolls with more uniform specifications that are easier to store, transport, and further process. The rubber roller 102 is installed on the rewinder 101. On the one hand, it relies on the friction between itself and the paper to stabilize the paper's movement and assist in the paper winding action, ensuring that the paper can be wound at a uniform speed and neatly during winding. On the other hand, it can also flatten and straighten the paper and assist in controlling the winding tension. The base 103 is used to support the rewinder 101.

[0033] The scraping assembly 200 is disposed on the rubber roller 102 and includes a scraping component 201 and a scraping sleeve 2011. The scraping sleeve 2011 is sleeved on the outside of the rubber roller 102 and is movably connected to the rubber roller 102. A movable ring 2012 is fixed on one side of the scraping sleeve 2011 and a pull rope 2013 is fixed at the bottom of the movable ring 2012.

[0034] One end of the scraping sleeve 2011 is set with an inclined surface. By moving the movable ring 2012, the movable ring 2012 can pull the pull rope 2013. The movement of the movable ring 2012 can drive the scraping sleeve 2011 to move on the rubber roller 102. At this time, the impurities on the rubber roller 102 can be scraped off through the inclined surface at one end. After scraping is completed, the scraping sleeve 2011 is released. At this time, the setting of the pull rope 2013 can drive the scraping sleeve 2011 back to its original position for the next use. When the rubber roller 102 rotates, the centrifugal force generated can limit the pull rope 2013, thereby preventing the scraping sleeve 2011 from moving on its own during use.

[0035] Example 2

[0036] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the scraping assembly 200 includes a rotating component 202, which includes a roller 2021. The roller 2021 is disposed inside the pull rope 2013, and a positioning frame 2022 is sleeved on the outside of the roller 2021. The positioning frame 2022 and the roller 2021 are rotatably connected by a bearing.

[0038] When the pull rope 2013 moves, it can drive the winding wheel 2021 to rotate. The rotation of the winding wheel 2021 can wind up the pull rope 2013. The positioning frame 2022 is sleeved on the outside of the rubber roller 102. The positioning frame 2022 and the rubber roller 102 are rotatably connected by a rotating shaft. The positioning frame 2022 is fixed on one side of the rewinder 101. The positioning frame 2022 can support the rubber roller 102.

[0039] Specifically, a rotating column 2023 is fixed to one side of the roller 2021, a rotating disk 2024 is fixed to one end of the rotating column 2023, a coil spring 2025 is fixed to one side of the rotating disk 2024, and one end of the coil spring 2025 is fixed to one side of the positioning frame 2022.

[0040] When the pull rope 2013 moves to unwind and drives the winding wheel 2021 to rotate, it can drive the rotating column 2023 to rotate. At this time, the rotation of the rotating column 2023 will drive the rotating disk 2024 to rotate. The rotation of the rotating disk 2024 can apply a torsional force to the coil spring 2025. The rotational force of the coil spring 2025 can drive the winding wheel 2021 to rotate and wind up the pull rope 2013.

[0041] Specifically, a limit plate 2026 is fixed on one side of the rotating disk 2024, a limit block 2027 is set on the top of the limit plate 2026, and a moving strip 2028 is fixed on the top of the limit block 2027.

[0042] A limiting groove corresponding to the limiting block 2027 is provided on the limiting plate 2026. When the rubber roller 102 rotates, it can drive the moving strip 2028 to move. At this time, the movement of the moving strip 2028 can drive the limiting block 2027 to engage with the limiting groove, thereby limiting the limiting plate 2026 and then limiting the roller 2021. When the rubber roller 102 stops rotating, the moving strip 2028 will return to its original position, causing the limiting block 2027 to separate from the limiting groove, thereby releasing the limiting of the limiting plate 2026.

[0043] Specifically, the scraping component 200 also includes a movable component 203, which includes a movable disk 2031. The movable disk 2031 is sleeved on the outside of the movable strip 2028. A first spring 2032 is fixed to the top of the movable disk 2031, and a positioning plate 2033 is fixed to one end of the first spring 2032.

[0044] When the limiting block 2027 moves and engages with the limiting groove, it can drive the moving disk 2031 to move. The movement of the moving disk 2031 can apply a pulling force to the first spring 2032. When the rubber roller 102 stops rotating, the rebound force of the first spring 2032 can drive the moving disk 2031 back to its original position, thereby allowing the limiting block 2027 to move and separate from the limiting groove, thus releasing the limiting of the limiting disk 2026. Then the scraping sleeve 2011 can move. The positioning plate 2033 is fixed to one side of the positioning frame 2022. The positioning plate 2033 is sleeved on the outside of the moving strip 2028. The positioning plate 2033 and the moving strip 2028 are movably connected. The positioning plate 2033 can support the moving strip 2028.

[0045] Example 3

[0046] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a ramp 2034 is fixed to the top of the moving bar 2028, a pressing block 2035 is provided on the top of the ramp 2034, and a moving rod 2036 is fixed to the top of the pressing block 2035.

[0048] An insert strip is inserted into the bottom of the inclined frame 2034. The inclined frame 2034 and the insert strip are movably connected. The insert strip is fixed to one side of the positioning frame 2022. When the rubber roller 102 rotates, it can drive the extrusion block 2035 to move. At this time, the movement of the extrusion block 2035 extrudes the inclined frame 2034, causing it to move. At the same time, the inclined frame 2034 can move on the insert strip, thereby preventing the inclined frame 2034 from shifting. The movement of the inclined frame 2034 can drive the limit block 2027 to move and engage with the limit groove.

[0049] Specifically, the scraping assembly 200 also includes a centrifugal component 204, which includes a squeezing sleeve 2041. The squeezing sleeve 2041 is fixed to one end of the moving rod 2036. An inclined column 2042 is provided on one side of the squeezing sleeve 2041. The inclined column 2042 and the squeezing sleeve 2041 are rotatably connected by a bearing. A squeezing rod 2043 is provided on one side of the inclined column 2042.

[0050] A support plate is fitted on the outside of the extrusion sleeve 2041. The extrusion sleeve 2041 and the support plate are movably connected. The support plate is fixed to one side of the positioning frame 2022. A counterweight is fixed to one end of the extrusion rod 2043. When the rubber roller 102 rotates, the counterweight can be moved by centrifugal force. At this time, the counterweight drives the extrusion rod 2043 to move. The movement of the extrusion rod 2043 can squeeze the inclined column 2042 and make it move. The movement of the inclined column 2042 can drive the extrusion sleeve 2041 to move. The movement of the extrusion sleeve 2041 can drive the moving rod 2036 to move.

[0051] The extrusion rod 2043 is inserted into one side of the rotating sleeve 2046, and the extrusion rod 2043 and the rotating sleeve 2046 are movably connected. The inclined column 2042 and the extrusion sleeve 2041 are both sleeved on the outside of the drive rod 2049, and the two are movably connected to the drive rod 2049.

[0052] Specifically, a connecting plate 2044 is sleeved on the outside of the extrusion rod 2043, a second spring 2045 is fixed on the top of the connecting plate 2044, and a rotating sleeve 2046 is sleeved on the outside of the second spring 2045.

[0053] When the counterweight moves due to centrifugal force, it can drive the connecting plate 2044 to move. At this time, the movement of the connecting plate 2044 can apply a squeezing force to the second spring 2045. When the rubber roller 102 stops rotating, the rebound force of the second spring 2045 can drive the counterweight back to its original position, thereby relieving the squeezing of the inclined column 2042. The rotating sleeve 2046 is sleeved on the outside of the squeezing sleeve 2041. The rotating sleeve 2046 and the squeezing sleeve 2041 are movably connected. The rotation of the rotating sleeve 2046 can generate centrifugal force to throw the counterweight out.

[0054] Specifically, a slider 2047 is fixed to one end of the inclined column 2042, and a third spring 2048 is fixed to one side of the slider 2047. The third spring 2048 is fixed to the inner wall of the rotating sleeve 2046.

[0055] A groove is provided inside the rotating sleeve 2046, and the slider 2047 slides in the groove. One end of the third spring 2048 is fixed to the inner wall of the groove. When the inclined column 2042 moves, it can drive the slider 2047 to slide in the groove. At this time, a squeezing force can be applied to the third spring 2048. When the rotating sleeve 2046 stops rotating, the rebound force of the third spring 2048 can drive the slider 2047 back to its original position.

[0056] Specifically, a drive rod 2049 is inserted into one side of the rotating sleeve 2046, and the drive rod 2049 is fixed to one end of the rubber roller 102.

[0057] The drive rod 2049 and the rotating sleeve 2046 are fixedly connected. When the rubber roller 102 is in use, it can drive the drive rod 2049 to rotate. At this time, the rotation of the drive rod 2049 can drive the rotating sleeve 2046 to rotate. The rotation of the rubber roller 102 is the prior art and will not be elaborated on here.

[0058] In use, the rubber roller 102 is started to rotate, which drives the drive rod 2049 to rotate. The drive rod 2049 then drives the rotating sleeve 2046 to rotate. The rotating sleeve 2046 rotates, which in turn drives the counterweight to rotate. The counterweight is then thrown out by centrifugal force. The movement of the counterweight drives the pressing rod 2043 to move. The movement of the pressing rod 2043 compresses the inclined column 2042, causing it to move. The movement of the inclined column 2042 then drives the pressing sleeve 2041 to move. The movement of the pressing sleeve 2041 then drives the moving rod 2036 to move. Simultaneously, the movement of the inclined column 2042 causes the slider 2047 to slide within the groove, thus applying a compressive force to the third spring 2048.

[0059] The moving rod 2036 can move the pressing block 2035, which in turn presses the inclined frame 2034, causing it to move. Simultaneously, the inclined frame 2034 can move on the insert bar, preventing it from shifting. The movement of the inclined frame 2034 can move the moving bar 2028, which in turn moves the moving disk 2031. The movement of the moving disk 2031 applies a pulling force to the first spring 2032. At this time, the movement of the moving bar 2028 can move the limiting block 2027 to engage with the limiting groove, thus limiting the disk 2026 and preventing it from shifting. When using the rubber roller 102, the scraper sleeve 2011 moves automatically. When the rubber roller 102 stops rotating and the centrifugal force is eliminated, the counterweight will return to its original position through the rebound force of the second spring 2045, thereby releasing the pressure on the inclined column 2042. At this time, the inclined column 2042 will return to its original position through the rebound force of the third spring 2048. At this time, the pressing block 2035 can release the pressure on the inclined frame 2034. Then, the rebound force of the first spring 2032 can drive the moving disk 2031 to return to its original position, thereby allowing the limiting block 2027 to move and separate from the limiting groove, thereby releasing the limitation on the limiting disk 2026. Then, the scraper sleeve 2011 can move.

[0060] By moving the movable ring 2012, the movable ring 2012 can pull the pull rope 2013. The movement of the movable ring 2012 can drive the scraping sleeve 2011 to move on the rubber roller 102. At this time, the impurities on the rubber roller 102 can be scraped off through the inclined surface at one end. At the same time, the movement of the movable ring 2012 can drive the pull rope 2013 to move. The movement of the pull rope 2013 can drive the winding wheel 2021 to rotate. When the pull rope 2013 moves, it unwinds and drives the winding wheel. When 2021 rotates, it can drive the rotating column 2023 to rotate. At this time, the rotation of the rotating column 2023 will drive the rotating disk 2024 to rotate. The rotation of the rotating disk 2024 can apply a torsional force to the coil spring 2025. After cleaning the rubber roller 102, the movable ring 2012 is released. The force of the coil spring 2025 rotating can drive the winding wheel 2021 to rotate and wind up the pull rope 2013, so that the scraping sleeve 2011 returns to its original position for the next use.

[0061] 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.
