Description

Technical Field

[0001] The utility model relates to the technical field of papermaking tools, in particular to a paper surface dust sticking device for a papermaking rewinder. Background Art

[0002] A rewinder is a specialized piece of papermaking equipment used to sequentially rewind the paper rolls produced by the papermaking machine. After rewinding, the paper is made into finished paper for shipment. The paper rolls produced by the rewinder are relatively soft, may be damaged or broken, have uneven edges, and are too wide to be used directly in paper processing or printing machines. Most paper types (such as newsprint, letterpress printing paper, and wrapping paper) must be trimmed, slit, and spliced ​​by the rewinder before being rewound onto a core to meet specific specifications and tightness requirements before shipment. The rewinding process generates a large amount of base paper dust. Without appropriate dust removal equipment on the rewinder, this can pose a health risk.

[0003] During the papermaking process, changes in the quality of raw materials can easily produce impurities such as paper fibers and dust on the finished paper sheets. Impurities are a major factor restricting the improvement of the quality of paper products.

[0004] The prior art discloses a patent with announcement number CN214243065U. The scheme includes a bottom plate, a shock-absorbing box is fixed on the top wall of the bottom plate, and lifting holes are opened at the four corners of the top wall of the shock-absorbing box. The gaps in the lifting holes are matched with vertical support columns, and the top ends of the four support columns extend to the top of the shock-absorbing box and are fixedly connected to a horizontal fixed plate. A buffer block is fixed on the bottom wall of the fixed plate, and a paper rewinding machine body is fixed on the top wall of the fixed plate. The bottom ends of the four support columns extend to the inside of the shock-absorbing box and are fixedly connected to a horizontal connecting plate. The two sides of the bottom wall of the connecting plate are respectively connected to the two sides of the inner bottom wall of the shock-absorbing box with a vertical first shock-absorbing spring, and the middle section of the inner top wall of the shock-absorbing box is fixed with a mounting seat. The utility model has a novel structure, generates less vibration during operation, and raises less paper dust during operation, which is beneficial to reducing the impact on the respiratory health of the operator. It has high practicality and is worthy of promotion.

[0005] The existing devices including the above patents have gradually exposed the shortcomings of the existing technology as they are used, mainly in the following aspects:

[0006] First, the paper fibers and dust particles generated during the papermaking process are small and will adhere to the surface of the product, affecting the overall quality and printing quality of the product. The paper fibers and dust will also float in the air over a large area, affecting the health of the workers.

[0007] Second, currently there are only simple exhaust fans for recycling paper fibers and dust, which cannot meet the requirements of different paper types for removing paper fibers and dust.

[0008] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0009] In response to the defects in the existing technology, the utility model is used to solve the problem that the paper fibers and dust particles generated in the papermaking production process of traditional technology are small and will adhere to the surface of the product, affecting the overall quality and printing quality of the product. The paper fibers and dust will also float in the air over a large area, affecting the health of the workers; and the current recycling of paper fibers and dust only has a simple exhaust fan, which cannot meet the requirements of different paper types for removing paper fibers and dust.

[0010] To achieve the above objectives, the present invention provides the following technical solutions:

[0011] A paper surface dust sticking device for a papermaking rewinder includes a bracket, with a mother roller and a paper feed roller rotating in parallel on both sides of the bracket. The bracket is rotated by a driving structure and is provided with a dust sticking roller that rises and falls vertically. The dust sticking roller is driven to rotate by a power structure. A dust sticking tape is mounted on the outer wall of the dust sticking roller. The dust sticking roller is located above the paper surface and is arranged parallel to the mother roller and the paper feed roller.

[0012] As an optimized solution, the driving structure includes a slide rail fixedly connected to the bracket in a vertical direction, a mounting frame is slidably provided on the slide rail, and the dust-sticking roller is rotatably mounted on the mounting frame.

[0013] As an optimized solution, the mounting frame is further fixedly connected to a walking platform located above the dust-sticking roller.

[0014] As an optimized solution, a lead screw is vertically rotatably mounted on the bracket, and a driving seat threadably connected to the lead screw is fixedly connected to the mounting frame.

[0015] As an optimized solution, a driving machine connected to the lead screw is fixedly connected to the upper end of the bracket.

[0016] As an optimized solution, a motor is fixedly connected to the side wall of the mounting frame, and the output end of the motor is connected to one end of the dust-sticking roller by a belt transmission structure.

[0017] As an optimized solution, the dust-sticking roller is an air expansion roller.

[0018] As an optimized solution, a guardrail is also fixedly connected to the walkway.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The sticky roller is driven by a driver to adjust its height along the slide rail to adapt to the height of the paper surface. The height can be adjusted to control the distance from the paper surface to meet the requirements of removing paper lint and dust for different paper types. There are limiters above and below the slide rail to effectively limit the moving range of the sticky roller.

[0021] The walkway and guardrail above can facilitate the replacement of sticky tape to ensure safety and reliability.

[0022] The utility model removes paper fibers and dust by using an adhesive tape, which can effectively save energy consumption compared with an exhaust fan. Moreover, the paper fibers and dust stuck to the adhesive tape are processed together with the replacement and processing of the adhesive tape, and there is no need to set up a box to collect the paper fibers, thus saving space and preventing disorderly processing of the paper fibers.

[0027] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2 As shown, a paper surface dust sticking device for a papermaking rewinder includes a bracket 1, and a mother roller 2 and a paper feed roller 3 are provided on both sides of the bracket 1 for rotation in parallel. The bracket 1 is rotated by a driving structure and is provided with a dust sticking roller 4 that rises and falls vertically. The dust sticking roller 4 is driven to rotate by a power structure, and a dust sticking tape is provided on the outer wall of the dust sticking roller 4. The dust sticking roller 4 is located above the paper surface and is arranged parallel to the mother roller 2 and the paper feed roller 3.

[0029] The driving structure includes a slide rail 13 fixedly connected to the bracket 1 in the vertical direction. A mounting frame 9 is slidably provided on the slide rail 13 , and the dust-sticking roller 4 is rotatably mounted on the mounting frame 9 .

[0030] The mounting frame 9 is also fixed with a walking platform 5 located above the dust-sticking roller 4.

[0031] A lead screw 7 is vertically rotatably mounted on the bracket 1 , and a driving seat 8 threadedly connected to the lead screw 7 is fixedly connected to the mounting frame 9 .

[0032] A driving motor 10 connected to the lead screw 7 is fixed to the upper end of the bracket 1 .

[0033] A motor 11 is fixedly connected to the side wall of the mounting frame 9 , and an output end of the motor 11 is connected to one end of the dust-sticking roller 4 via a belt transmission structure 12 .

[0034] The dust-sticking roller 4 is an air expansion roller.

[0035] A guardrail 6 is also fixedly connected to the walking platform 5.

[0036] The motor 11 uses the belt transmission structure 12 to adjust the rotation speed of the dust-sticking roller 4 so that it is basically consistent with the moving linear speed of the paper, thereby ensuring the efficiency of sticking paper hair and dust.

[0037] The working principle of this device is:

[0038] The sticky roller 4 is driven by the driving machine 10 to adjust its height along the slide rail 13 to adapt to the height of the paper surface. The height can be adjusted to control the distance from the paper surface to meet the requirements of removing paper lint and dust for different paper types. There are limiters above and below the slide rail 13 to effectively limit the movement range of the sticky roller 4.

[0039] The upper platform 5 and guardrail can facilitate the replacement of the sticky tape to ensure safety and reliability.

[0040] The utility model removes paper fluff and dust by using the adhesive tape, which can effectively save energy consumption compared with an exhaust fan. In addition, the paper fluff and dust stuck to the adhesive tape are processed together with the replacement and processing of the adhesive tape, and there is no need to set up a box to collect the paper fluff, which saves space and prevents disorderly processing of the paper fluff.

[0041] When replacing the sticky tape, the crane is used to lift the sticky roller 4. The platform 5 and handrails provide easy access for personnel to operate the device. The sticky tape is then replaced on the inflatable roller. The working principle of the inflatable roller is to inflate the roller with air through the air nozzle, causing the key strip on the roller body to protrude and press against the external component, namely the sticky tape. To release the air, press the sliding air core on the air nozzle to deflate the key strip, which will return to its original shape and the sticky tape can be removed.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
