Description

Technical Field

[0001] The utility model relates to the technical field of web paper rewinder improvements, mainly relating to a cleaning device, in particular to a device for cleaning paper dust from an embossing roller of a rewinder and a paper winding device. Background Art

[0002] The web rewinder is a very important piece of equipment in the papermaking industry. It is mainly used to rewind large rolls of base paper into smaller finished rolls suitable for sale or further processing according to certain specifications. In addition to simple slitting and rewinding, this process may also include embossing (i.e., edge embossing) and gluing to enhance the aesthetics or functionality of the product. Among them, the embossing roller is a key component used to complete the embossing task. By pressing a specific pattern or texture on the surface of the paper, the visual appeal of the product is enhanced; some designs can also improve the feel, such as increasing softness or improving absorption performance; they can also be used as part of brand identification, such as printing a company logo or other information. However, during the production process, if the humidity in the production environment is too high, the moisture content of the paper will increase, and the embossing roller will easily absorb some paper scraps and entangle some of the paper scraps, which will stick to the surface of the embossing roller. In addition, too high or too low working temperatures may also cause the properties of paper fibers to change, making them more likely to adhere to the embossing roller. Some paper materials use raw materials containing too many short fibers or inappropriate additive ratios, and this type of paper is often more likely to form small fragments and adhere to the embossing roller.

[0003] If these scraps of paper are not properly cleaned and maintained over a long period of time, the surface of the embossing roller will become rough or even damaged, which not only reduces work efficiency but also promotes the accumulation of paper scraps. Once this happens, it will have the following impacts on the entire production line: 1. Reduced efficiency: Frequent shutdowns for cleaning will undoubtedly interrupt the normal production process and seriously affect output. 2. Damage to product quality: Residues may be transferred to subsequent products, causing cosmetic defects or even functional failure. 3. Increased cost expenditure: Additional manpower and potential product scrapping will result in financial losses for the company. 4. Increased safety hazards: Workers need to be close to high-speed machinery to perform cleaning operations, which poses a high risk of personal injury. Therefore, timely cleaning of the embossing roller is a very necessary maintenance work.

[0004] Currently, web rewinders lack devices for cleaning paper dust or paper entanglement on the embossing rollers. When paper dust or paper entanglement occurs during the production process, the machine must be stopped for manual cleaning. This technical downtime affects production efficiency. Failure to promptly clean the sticky paper can lead to delamination and crushing of the embossing, and paper dust entering the product. Cleaning paper dust and paper entanglement poses a safety hazard, with personnel falling (2.2 meters from the ground) and mechanical injuries. The common scraper-based cleaning method for the roller surface in existing technologies also suffers from low efficiency, poor cleaning results, and incompleteness. Summary of the Invention

[0005] In order to address the shortcomings and defects of the above-mentioned existing technologies, the present invention aims to achieve automatic online cleaning without the need for manual cleaning of paper dust and paper entanglements. The improvement can improve production efficiency, reduce the risk of embossing delamination or crushing and the quality of paper entanglements, avoid the safety hazards of people falling and mechanical pinching, and improve cleaning quality. Specifically, the present invention is achieved as follows:

[0006] The invention relates to a device for cleaning paper dust from an embossing roller of a rewinder and a paper winding device, which is installed above the embossing roller of the rewinder and comprises: a bracket shell in the shape of a cover body and is installed on the bearing part of the embossing roller of the rewinder or on the bracket around the embossing roller of the rewinder, which can cover the upper half of the embossing roller of the rewinder; and can serve as a bracket body for a lifting and cleaning paper dust mechanism; the lifting and cleaning paper dust mechanism comprises a lifting control component, a lifting rod and a scraper assembly, the lifting control component is installed on the bracket shell and is connected to the scraper assembly through the lifting rod, the scraper assembly is arranged along the length direction of the embossing roller of the rewinder, and the scraper assembly can be lifted and lowered relative to the embossing roller of the rewinder under the control of the lifting control component and the lifting rod, and can contact the embossing roller of the rewinder when it is lowered into place The electrostatic paper dust removal mechanism includes an electrostatic ion rod and an air outlet, which is a rod-shaped structure and is installed on the bracket shell or the bracket around the embossing roller of the rewinder along the length direction of the rewinder embossing roller. The air outlet direction of the air outlet is set above the area between the lifting and cleaning paper dust mechanism and the dust exhaust mechanism, which is used to spray air flow with negative ions or positive ions and contact the roller surface of the rewinder embossing roller to neutralize and offset the charge of the entangled paper or paper scraps, and blow them away from the roller surface; the dust exhaust mechanism is a groove-shaped structure, which is arranged along the length direction of the rewinder embossing roller, located obliquely below the scraper assembly, and close to the roller surface of the rewinder embossing roller, and is used to collect the cleaned paper scraps and paper residues.

[0007] Furthermore, the lifting rod is a gear rack with a rod-shaped structure, and the lifting control component includes a lifting drive mechanism, a transmission gear, and a gear rack. One end of the transmission gear is engaged and linked with the output gear of the lifting drive mechanism, and the other end is engaged and linked with the tooth portion of the gear rack. The bottom of the gear rack is connected to the scraper assembly, and the lifting drive mechanism can drive the gear rack to rise and fall through the transmission gear, thereby driving the scraper assembly to rise and fall; the length specification of the gear rack ensures that the scraper assembly can just contact the roller surface of the embossing roller of the rewinder.

[0008] Furthermore, the lifting drive mechanism is a lifting motor, and the output shaft of the lifting motor is equipped with a motor output gear that fits with the first transmission gear, and the lifting and lowering of the gear rack is controlled by the forward and reverse rotation of the lifting motor.

[0009] Furthermore, the lifting drive mechanism is a hand-cranked handwheel, and the output shaft of the hand-cranked handwheel is equipped with a manual output gear that fits with the second transmission gear. The lifting and lowering of the gear rack is controlled by the forward and reverse rotation of the hand-cranked handwheel.

[0010] Furthermore, the lifting drive mechanism includes a lifting motor and a hand-cranked hand wheel, each of which is placed above the two ends of the embossing roller of the rewinder, and is respectively connected to a gear rack through a first transmission gear and a second transmission gear. The first transmission gear and the second transmission gear are connected by a connecting rod shaft. The scraper assembly can be driven to rise and fall only by the hand-cranked hand wheel, and can also be driven to rise and fall only by the lifting motor.

[0011] Furthermore, the scraper assembly includes an arc-shaped mounting bar, the cross-section of the arc-shaped mounting bar is arc-shaped, and the curvature is adapted to the curvature of the embossing roller of the rewinder. A scraper bar is installed on one side of the inner side surface of the arc-shaped mounting bar, and a brush is installed on the other side. The scraper bar is installed on the side facing the dust exhaust mechanism and contacts the roller surface of the rewinder before the brush.

[0012] Furthermore, the air outlet holes of the electrostatic paper dust removal mechanism face the roller surface area between the scraper bar and the dust discharge mechanism. There are several air outlet holes, which are evenly distributed along the length direction of the electrostatic paper dust removal mechanism. The air outlet holes are close to one side of the scraper bar and discharge air obliquely, so that the air flow direction flows along the roller surface toward the dust discharge mechanism.

[0013] Furthermore, a negative pressure suction pipe is connected to the back or side of the dust discharge mechanism, and the negative pressure suction pipe is connected to the terminal filter and the negative pressure mechanism for continuously or intermittently sucking away the paper scraps and residues in the dust discharge mechanism.

[0014] Furthermore, the dust exhaust mechanism, the electrostatic paper dust removal mechanism and the lifting and cleaning paper dust mechanism are all installed on the bracket shell, and a dust cover is also provided on the outside of the lifting control component.

[0015] The working principle of the utility model: the bracket shell of the present invention serves as the bracket and shell of the whole device. On the one hand, it is placed on one side of a single pressing roller and is used to install a scraper mechanism that can be lifted and lowered relative to the roller surface. When the embossing roller is working normally, the scraper assembly does not participate in the action. At this time, it is separated from the roller surface of the pressing roller and does not contact it, which does not affect the normal operation of the pressing roller. When cleaning is required, the lifting and cleaning paper dust mechanism is controlled to descend and make the scraper assembly contact with the roller surface of the embossing roller, and physically scrape and clean the entangled paper and adhered paper scraps on it, removing most of the paper scraps that need to be cleaned and a small part that is relatively The broken paper scraps are light in weight and carry static electricity due to friction, which makes them adsorbed on the scraper or roller surface and difficult to remove with a scraper or brush. At this time, the air holes of the electrostatic paper dust removal mechanism spray charged (negative or positive ion) airflow to the surface of the embossing roller to neutralize the charge of the paper scraps attached to the roller surface; once the charge of the paper scraps is neutralized, they are more likely to fall off the embossing roller, making it easier for them to fall off and move with the air flow, eventually entering the dust exhaust mechanism; the air outlet holes also play a sweeping role, blowing the loosened or neutralized paper scraps to the dust exhaust mechanism below. The direction of the airflow is obliquely downward, which helps to guide the paper scraps to flow toward the dust exhaust mechanism, and can act on the scraper and roller surface to improve cleaning efficiency. The dust exhaust mechanism is located below the scraper assembly and is a trough-like structure used to collect the cleaned paper scraps and paper scraps. In order to improve the dust removal efficiency, the dust removal mechanism is connected to a negative pressure suction pipe, which can discharge the collected waste through the terminal filter to keep the working area clean. It should be noted that the size of the suction port is relatively large, slightly larger than the larger size of the paper wrapping and debris, so that the suction port is not easily blocked. In terms of lifting power control, the lifting control component can be either electrically driven (through a motor) or manually operated (hand-cranked handwheel), or even a combination of the two, to ensure the flexibility of the equipment in different scenarios. It should be noted that if it is an embossing roller with a roller structure, the roller body structure at the lower end, the bracket shell and the scraper assembly are not placed at the top, but are placed in the front or rear of the lower side, and are installed adaptively according to the actual environmental conditions; or the embossing roller can be directly disassembled and installed separately with this device for cleaning.

[0016] Beneficial technical effects of the utility model:

[0017] (1) Improve cleaning efficiency: The scraper assembly of the paper dust removal mechanism is raised and lowered to physically scrape away most of the entangled and adhered paper scraps. At the same time, the electrostatic paper dust removal mechanism ejects a charged (negative or positive) airflow to neutralize the charge of the paper scraps, making it easier to remove the debris attached to the scraper or roller surface due to static electricity. The scraper bar contacts the embossing roller before the brush, ensuring that larger paper scraps are removed first, and then the brush is used to further clean the fine paper scraps.

[0018] (2) Automation and flexibility: The lifting control components can be electrically driven (lifting motor), manually operated (hand-cranked handwheel), or even a combination of the two to meet the needs of different scenarios. The dust removal mechanism is connected to a negative pressure suction pipe, which can continuously or intermittently discharge the collected waste to keep the debris collection area clean.

[0019] (3) Compact structure and easy installation: The bracket housing serves as both a bracket and a housing, and its compact structure makes it easy to install on the bearing part of the embossing roller of the rewinder or on the surrounding bracket. During normal operation, the scraper assembly does not contact the embossing roller, which does not affect its normal operation. When cleaning is required, the scraper assembly is lowered by the lifting mechanism and contacts the embossing roller, completing the cleaning quickly and reducing equipment downtime.

[0020] (4) Improve production quality: Through the efficient cleaning mechanism, paper scraps and paper entanglement on the embossing roller are reduced, ensuring the quality and consistency of paper products. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0034] Example 1: A device for cleaning paper dust from the embossing roller of a rewinder and wrapping paper, installed above the embossing roller of the rewinder, having the following structure:

[0035] The bracket shell is installed on the bearing part of the rewinder embossing roller or on the bracket around the rewinder embossing roller in the shape of a cover. It can cover the upper part of the rewinder embossing roller, playing a role of protection and isolation. It can also serve as the bracket body of the lifting and cleaning mechanism of the paper dust, providing stable support. It is usually installed on the machine body next to the rewinder embossing roller.

[0036] The lifting and dust cleaning mechanism includes a lifting control component, a lifting rod and a scraper assembly. The lifting control component is installed on the bracket shell and is connected to the scraper assembly through the lifting rod. The scraper assembly is arranged along the length direction of the embossing roller of the rewinder. The scraper assembly can be lifted and lowered relative to the embossing roller of the rewinder under the control of the lifting control component and the lifting rod. When it is lowered into place, it can contact the roller surface of the embossing roller of the rewinder to clean paper dust residues on the roller surface. Such a design allows the cleaning device to be installed on the embossing roller without affecting the normal use of the embossing roller. When cleaning is required, the lifting and dust cleaning mechanism is lowered into place, and the scraper assembly acts on the roller surface for cleaning, and then resets after completion.

[0037] The electrostatic paper dust removal mechanism includes an electrostatic ion rod and an air outlet. It is a rod-shaped structure and is installed on the bracket shell or the bracket around the rewinder embossing roller along the length direction of the rewinder embossing roller. The air outlet direction of the air outlet is set above the area between the lifting and cleaning paper dust mechanism and the dust exhaust mechanism. It is used to spray air with negative or positive ions and contact the roller surface of the rewinder embossing roller to neutralize and offset the charge of the entangled paper or paper scraps, and blow them away from the roller surface. Because a large amount of small-volume debris will be adsorbed on the roller surface and scraper due to static electricity and cannot fall normally to be cleaned, electrostatic ion wind is needed to contact the roller surface of the rewinder embossing roller to neutralize and offset the charge of the entangled paper or paper scraps. The neutralized paper scraps are blown away from the roller surface into the dust exhaust mechanism through the airflow.

[0038] The dust removal mechanism is a trough-shaped structure arranged along the length of the rewinder's embossing roller. It is located diagonally below the scraper assembly and close to the roller surface of the rewinder's embossing roller. It is used to collect the scraps and paper residue removed by the scraper assembly.

[0039] Lifter Structure: The lift drive mechanism is the power source, typically consisting of a motor or other type of drive device. Its output end features a gear (called the output gear) that transmits power to other components. A transmission gear, connected between the lift drive mechanism's output gear and the rack and pinion, acts as an intermediate power transmitter. One end of the transmission gear meshes with the lift drive mechanism's output gear, while the other end meshes with the rack and pinion, transferring power from the drive mechanism to the rack and pinion. The rack and pinion is a linear motion mechanism with teeth on one side that mesh with the drive gear. When the drive gear rotates, the rack and pinion moves up and down. The base of the rack and pinion is connected to the scraper assembly, so as the rack and pinion move up and down, the scraper assembly also moves with it. The rack and pinion are designed to be just the right length, ensuring that the scraper assembly maintains contact with the rewinder's embossing roller during lifting and lowering. This ensures that the scraper assembly is neither too far away to contact the roller surface nor too close to create excessive pressure or friction during operation.

[0040] Another type of lift drive is a manual handwheel. This is a manual device that the user can directly operate, providing driving force through forward or reverse rotation. The handwheel typically has a handle to facilitate user application of force. The manual output gear is mounted on the output shaft of the handwheel. When the handwheel rotates, the output shaft rotates with it, driving the manual output gear to rotate along with it. The second transmission gear meshes with the manual output gear. The rotation of the manual output gear is transmitted to the second transmission gear through meshing action. The second transmission gear typically meshes with a gear rack (i.e., a linear guide with teeth). As the second transmission gear rotates, it moves along the rack, achieving lifting and lowering motion. When the user rotates the handwheel forward, the output shaft drives the manual output gear to rotate clockwise. The rotation of the manual output gear is transmitted to the second transmission gear through meshing action, causing it to also rotate clockwise. The rotation of the second transmission gear pushes the rack upward, achieving the lifting action. Conversely, when the user rotates the hand-cranked handwheel in the opposite direction, the manual output gear rotates counterclockwise, and the second transmission gear also rotates counterclockwise, pushing the rack downward to achieve the descending action.

[0041] Preferably, the lifting motor and hand-cranked handwheel are integrated, each positioned above the embossing roller at either end of the rewinder. Each is connected to a gear rack via a first transmission gear and a second transmission gear, respectively. The first and second transmission gears are connected via a connecting rod shaft. This allows the scraper assembly to be raised and lowered solely by the hand-cranked handwheel or solely by the lifting motor. When the lifting motor is used, the motor drives the gear rack via the first transmission gear, thereby raising and lowering the scraper assembly. Because the first and second transmission gears are connected by the connecting rod shaft, the second transmission gear also rotates, driving the gear rack on the other side to rise and fall synchronously. When the hand-cranked handwheel is used, the handwheel drives the second transmission gear via its output shaft, which in turn drives the gear rack on the other side to rise and fall synchronously. Similarly, because the first and second transmission gears are connected by the connecting rod shaft, the first transmission gear also rotates, driving the gear rack on the other side to rise and fall synchronously. The system can manually raise and lower the scraper assembly solely by the hand-cranked handwheel or automatically by the lifting motor alone. Regardless of the drive mode used, the gear racks on both sides can maintain synchronous movement to ensure the smooth lifting and lowering of the scraper assembly.

[0042] The scraper assembly consists of a curved mounting bar with an arc-shaped cross-section that matches the curvature of the rewinder's embossing roller. A scraper bar is mounted on one side of the inner side of the curved mounting bar, and a brush is mounted on the other side. The scraper bar is mounted on the side facing the dust removal mechanism and contacts the rewinder's embossing roller surface before the brush. The scraper bar first contacts the rewinder's embossing roller surface, using its sharp edge to remove larger impurities and dirt. The brush follows closely, using its soft bristles to further remove fine impurities from the roller surface, ensuring a thorough clean. The scraper assembly, through its curved mounting bar, scraper bar, and brush design, effectively cleans the rewinder's embossing roller surface.

[0043] The electrostatic dust removal mechanism's air outlet faces the roller surface area between the scraper bar and the dust removal mechanism. Several outlets are evenly distributed along the length of the mechanism. These outlets are located close to the scraper bar and distribute air diagonally, directing airflow along the roller surface toward the dust removal mechanism. This ensures that the ionized airflow reaches the entire roller surface area.

[0044] Preferably, a negative pressure suction pipe is connected to the back or side of the dust removal mechanism, which is connected to the terminal filter and the negative pressure mechanism to continuously or intermittently suck away the paper scraps and debris in the dust removal mechanism. It is usually used in conjunction with an electrostatic paper dust removal mechanism. The suction pipe is installed below the electrostatic paper dust removal mechanism and can follow the airflow of the electrostatic paper dust removal mechanism. The debris and paper scraps carried away by the scraper assembly and the airflow enter the dust removal mechanism, where they are sucked away by the negative pressure and filtered and stored in a centralized manner.

[0045] The dust removal mechanism, electrostatic paper dust removal mechanism and lifting and cleaning paper dust mechanism are all installed on the bracket shell. This structural design is unified, compact and complete. A dust cover is also provided on the outside of the lifting control component to protect the lifting structure from being affected by dust.

[0046] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
