Description

Technical Field

[0001] This utility model relates to the field of paper processing equipment technology, and in particular to an edge trimming assist tool for paper processing. Background Technology

[0002] In modern high-speed paper processing production lines, to ensure the quality of the finished paper and production efficiency, the paper web must remain highly flat and stable during the process of being transported from the forming section to the drying section. For this purpose, a paper-stabilizing bellows is usually installed at the inlet of the drying cylinder. The negative pressure suction generated by the bellows firmly adheres the paper web, especially the edges, to the conveyor wire, resisting the disturbance caused by the high-speed airflow.

[0003] However, during long-term continuous production, the air inevitably carries fine paper fibers and lint that detach from the paper web itself, as well as impurities such as cleaning agents used to maintain the dry wire. These impurities are drawn into the suction slits of the paper stabilizing air box by the airflow and gradually deposit and accumulate, eventually causing blockages in the suction slits, especially the edge suction slits with lower airflow.

[0004] Once the suction seams at the edge of the paper-stabilizing bellows become clogged, its suction force on the paper web edge will significantly weaken or even disappear completely. At this point, the paper edge, no longer effectively restrained, is easily lifted upwards by the high-speed airflow as it enters the drying cylinder, forming a floating edge phenomenon. This floating edge not only directly causes subsequent paper sheets to fold and wrinkle, severely affecting product quality, but may even lead to paper breaks, forcing the entire production line to shut down for cleaning, resulting in huge production losses. Currently, the industry generally lacks an auxiliary structure that can effectively intervene in unexpected situations without shutting down the production line.

[0005] Therefore, this utility model proposes an edge-flaring assistance tool for paper processing to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problem that existing paper processing equipment lacks an effective auxiliary structure to stabilize the paper web edge after the edge of the stabilizing bellows becomes clogged, resulting in unstable production and reduced product quality, this utility model aims to provide a paper processing edge-fluttering assistance tool with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a paper processing edge trimming assistance tool, including: a conveyor, a drying cylinder, a fixing frame and a paper stabilizing air box, and an air blowing auxiliary mechanism consisting of a support, an air blowing pipe and an air pump.

[0008] The blowing pipe has multiple blowing holes on its wall, and the blowing direction of the blowing holes is towards the edge of the paper web.

[0009] Furthermore, the fixed frame is fixedly installed on the conveyor and located on the paper feeding side of the drying cylinder, and the paper stabilizing air box is fixedly installed inside the fixed frame; the bracket is set on the paper feeding side of the drying cylinder, the air blowing pipe is fixed on the bracket through a fixing assembly, and the outlet of the air pump is pneumatically connected to the air blowing pipe.

[0010] Preferably, the fixing component includes a fixing ring and at least one bolt, the fixing ring being sleeved on the outside of the air tube, and the bolt passing through the fixing ring and threadedly connected to the bracket.

[0011] Preferably, a valve is connected in series between the air blowing pipe and the air pump, and a pressure gauge is fixedly installed at the end of the air blowing pipe.

[0012] Preferably, the air blowing pipe is fixed parallel to the axial direction of the drying cylinder, and the air blowing holes are distributed along the length direction of the air blowing pipe.

[0013] Preferably, the paper processing edge trimming assist tool further includes an inclined scraper, which is mounted on the conveyor and located on the paper feed side of the fixed frame.

[0014] Preferably, a connecting plate is fixedly installed on the outer side of the inclined scraper, and both ends of the connecting plate are fixedly connected to the conveyor by fixing blocks.

[0015] Preferably, the bottom of the paper-stabilizing air box is located above the top surface of the conveyor.

[0016] Preferably, the paper processing edge trimming assist tool further includes an unwinder and a rewinder, the unwinder being installed at the paper inlet end of the conveyor and the rewinder being installed at the paper outlet end of the drying cylinder.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by adding a set of air blowing auxiliary mechanism consisting of a support, an air blowing pipe and an air pump on the paper feeding side of the drying cylinder, the mechanism can blow air in a directional manner toward the edge of the paper web, which solves the problem of paper web edge drifting and wrinkling caused by blockage failure of the paper stabilizing air box in the prior art. It achieves the technical effect of actively applying stabilizing force to replace the failed adsorption force without interrupting production, thus ensuring production continuity and product quality.

[0018] 2. In this utility model, by setting valves and pressure gauges on the air blowing pipeline, the problem of fixed auxiliary airflow intensity and inability to adapt to different working conditions is solved. This enables operators to accurately adjust the air blowing intensity in real time according to paper type, machine speed or severity of edge bleeding, thereby improving the versatility and operational accuracy of the device.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example 1

[0021] Please refer to Figures 1 to 4 This utility model provides a paper processing edge-dragging assistance tool, which aims to solve the problem that when the edge suction seam of the paper stabilizing bellows in existing paper processing equipment fails due to blockage, there is a lack of structure to stabilize the edge of the paper web, which leads to the paper easily dragging and wrinkling.

[0022] Specifically, refer to Figure 1 An edge-trimming assist tool for paper processing includes a conveyor 2, a drying cylinder 5 installed at one end of the conveyor 2, an unwinder 1 installed at the paper inlet end of the conveyor 2, and a rewinder 3 installed at the paper outlet end of the drying cylinder 5. A fixing frame 6 is fixedly installed on the conveyor 2, located on the paper inlet side of the drying cylinder 5. A paper-stabilizing air box 7 is fixedly installed inside the fixing frame 6, with its bottom located above the top surface of the conveyor 2. The core of this solution is the provision of an air-blowing auxiliary mechanism, which includes a bracket 4, an air-blowing pipe 11, and an air pump 17. The bracket 4 is located on the paper inlet side of the drying cylinder 5, and the air-blowing pipe 11 is fixed to the bracket 4 by a fixing assembly. Further, referring to... Figure 3The fixing assembly includes a fixing ring 13 and a bolt 14. The fixing ring 13 is sleeved on the outer periphery of the air blowing pipe 11, and the bolt 14 passes through the fixing ring 13 and is threaded to the bracket 4. In this way, the air blowing pipe 11 is firmly fixed. Multiple air blowing holes 12 are opened on the pipe wall of the air blowing pipe 11. The air blowing direction of the air blowing holes 12 is towards the edge of the paper web, and the air blowing pipe 11 is fixed parallel to the axial direction of the drying cylinder 5. The air blowing holes 12 are distributed along the length of the air blowing pipe 11, and their distribution range is adapted to the width of the edge of the paper web. The outlet of the air pump 17 is pneumatically connected to the air blowing pipe 11 to provide compressed air. A valve 16 is connected in series between the air blowing pipe 11 and the air pump 17 to regulate the airflow. A pressure gauge 15 is also fixedly installed at the end of the air blowing pipe 11 to monitor the air blowing pressure.

[0023] The core of the technical solution in this embodiment lies in providing a blowing auxiliary mechanism capable of actively applying a stabilizing force, and this blowing auxiliary mechanism forms a precise positional fit with the drying cylinder 5. Please refer to the following for details. Figure 1 and Figure 3 The core structure will be described in detail below: The air blowing auxiliary mechanism includes a bracket 4 serving as the mounting base, which is positioned on the paper feed side of the drying cylinder 5. An air blowing pipe 11 is fixedly connected to the bracket 4 via a fixing assembly consisting of a fixing ring 13 and bolts 14. The inner wall of the fixing ring 13 is fitted against the outer wall of the air blowing pipe 11 and sleeved onto it. The bolts 14 pass through the fixing ring 13 and are threadedly connected to the bracket 4, thus achieving a stable installation of the air blowing pipe 11. Multiple air blowing holes 12 are machined into the wall of the air blowing pipe 11. The axes of the air blowing holes 12 are inclined, so that their blowing direction is towards the edge of the paper web. The installation position of the air blowing pipe 11 ensures that the airflow from the air blowing holes 12 can accurately act on the paper web before it enters the drying cylinder 5. In the edge region, the air pump 17 serves as the air source, and its outlet is pneumatically connected to the inlet of the air blowing pipe 11 via a pipeline. A valve 16 is installed in series on the pipeline between the air pump 17 and the air blowing pipe 11. The valve 16 is used to open, close, or regulate the air flow in the air path. A pressure gauge 15 is also fixedly installed at the end of the air blowing pipe 11. The pressure gauge 15 is used to display the gas pressure inside the air blowing pipe 11 in real time. This combination of structures allows a controllable and stable directional airflow to be generated from the air blowing hole 12 by starting the air pump 17 and adjusting the valve 16 when the paper stabilizing air box 7 fails. This airflow applies pressure to the edge of the paper web, thereby replacing the adsorption stabilizing effect missing by the paper stabilizing air box 7 and pressing the edge of the paper web tightly.

[0024] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to pre-clean the paper web before it enters the paper stabilizing air box 7, please refer to... Figure 1 and Figure 4The tool also includes an inclined scraper 8, which is mounted on the conveyor 2. Its mounting position is located on the paper feed side of the fixed frame 6. In order to ensure the stability of the inclined scraper 8 during operation, its outer side is fixedly connected to the conveyor 2 through a connecting plate 9. Furthermore, the two ends of the connecting plate 9 are fixedly connected to the side wall of the conveyor 2 by welding or bolting through fixing blocks 10. The bottom edge of the inclined scraper 8 is in contact with or has a preset small gap with the paper web surface running on the conveyor 2 so as to scrape off impurities on the paper surface.

[0025] In another preferred embodiment, in order to realize the complete paper processing process, the tool also includes an unwinder 1 and a rewinder 3. The unwinder 1 is installed at the paper feed end of the conveyor 2 for releasing the paper web, and the rewinder 3 is installed at the paper output end of the drying cylinder 5 for winding the dried paper web.

[0026] In another preferred embodiment, the paper stabilizing air box 7 is installed inside the fixed frame 6, with its bottom located above the top surface of the conveyor 2. During the conveying process, the paper web passes under the paper stabilizing air box 7, and the air inlet of the paper stabilizing air box 7 faces the paper web to provide adsorption and stabilization.

[0027] Working principle: During the paper processing, the paper web is released by the unwinder 1 and conveyed by the conveyor 2. During the conveying process, the inclined scraper 8 installed on the conveyor 2 cleans the surface of the paper. When the paper stabilizing air box 7 installed in the fixed frame 6 is blocked at the edge suction seam due to the accumulation of paper hair and dry wire cleaning agent over a long period of time, the edge of the paper web will lose the adsorption and stabilization effect of the paper stabilizing air box 7 when it enters the drying cylinder 5, resulting in the phenomenon of fluttering edges, which causes the paper to not stick to the dry wire and is easy to wrinkle.

[0028] At this time, the air pump 17 is started to generate compressed air. After being regulated by the valve 16, the compressed air is transmitted through the air blowing pipe 11 installed on the bracket 4. The operator can observe the reading of the pressure gauge 15 installed at the end of the air blowing pipe 11 and adjust the opening of the valve 16 to control the airflow intensity. The airflow is finally blown out in a direction through the air blowing hole 12 on the air blowing pipe 11 and acts on the edge of the paper web where the edge is fluttering. This actively applied airflow makes up for the air pressure stabilization effect lost due to the blockage of the suction seam at the edge of the paper stabilizing air box 7, so that the edge of the paper is re-stressed and tightly attached to the dry wire, thereby eliminating the fluttering and wrinkling phenomenon. After the paper web is dried by the drying cylinder 5, it is wound up by the winding machine 3.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
