Description

Technical Field

[0001] This patent relates to the field of new tobacco production equipment, specifically to a cutting knife protection device. Background Technology

[0002] In modern tobacco industry production, the cigarette filter rod slitting process is a crucial link connecting filter rod forming and cigarette rolling, and its technological level directly affects product quality and production efficiency. Traditional cigarette filter rod slitting equipment typically employs a double-ended fixed shaft structure design. This type of structure uses two parallel mounting plates on the frame, employing bearings to rigidly fix both ends of the shaft that carries the slitting blade, creating a closed mechanical transmission system. This design, to a certain extent, ensures the structural stability of the slitting blade and can meet basic production requirements. However, this structure has many drawbacks, limiting its application in modern production. From an equipment maintenance and operation perspective, the slitting blade, due to the double-ended fixed shaft, is partially or completely enclosed within the frame's internal space. When the slitting blade's position needs adjustment, operators must disassemble the bearings and shaft assembly within the narrow space of the mounting plates, using specialized disassembly tools. This not only consumes a significant amount of time and effort but also results in low disassembly efficiency due to limited operating space. More seriously, the exposed sharp edges of the slitting blades can easily cause cuts to operators during repeated disassembly and assembly, posing a significant safety hazard and making equipment maintenance a major bottleneck restricting production efficiency. Regarding equipment operation monitoring, the enclosed structural design of existing technologies limits real-time visual observation of the slitting blade's working status. Abnormal wear and positional misalignment that may occur during high-speed operation are difficult to detect directly while the equipment is running. Production personnel can only conduct inspections by periodically stopping the machine and disassembling the equipment casing. This passive monitoring method not only frequently interrupts the production process and reduces equipment utilization, but may also lead to deviations in filter rod slitting dimensions due to the inability to detect blade abnormalities in a timely manner, resulting in a large number of defective products and seriously affecting product qualification rates and corporate economic benefits. With the accelerating pace of tobacco industry production, the lag in monitoring of existing slitting equipment is becoming increasingly apparent, urgently requiring technological innovation to meet the demands of modern production. Utility Model Content

[0003] The purpose of this invention is to provide a cutting knife protection device with a simple structure that can effectively improve safety, production efficiency, yield, and compatibility with different production lines.

[0004] To ensure the safety and compatibility of the cutting device, reduce the defect rate during the baking process, and improve the baking quality of tobacco leaves, this patent provides the following technical solutions:

[0005] A cutting blade protection device includes: a drive module for providing power; an execution module rotatably connected to the drive module for performing cigarette cutting operations; and a protection module disposed outside the execution module, the protection module including an openable and closable protective door and a fixedly mounted enclosure assembly, the protective door and the enclosure assembly being hinged to form an open cavity structure, the cavity structure at least partially surrounding the cutting end of the execution module, and the protective door and the enclosure assembly having two cooperative relationships: in a closed state, the protective door can be securely fixed to the enclosure assembly to prevent accidental opening during equipment operation; in an open state, the protective door can be opened from the enclosure assembly to allow maintenance and adjustment of the execution module.

[0006] Furthermore, the execution module includes bearing components, rotating shaft components, and cutting components.

[0007] Furthermore, one end of the rotating shaft is mounted to the drive module via a bearing.

[0008] Furthermore, the other end of the rotating shaft is connected to the cutting component.

[0009] Furthermore, the drive module includes: a drive element for providing rotational power; and a base for fixing the drive element.

[0010] Furthermore, the driving component is a motor, which transmits power to the rotating shaft to drive the cutting workpiece to rotate.

[0011] Furthermore, the protective door is arranged parallel to the cutting surface of the cutting component and / or perpendicular to the axis of the rotating shaft.

[0012] Furthermore, the protective door is securely fixed to the support assembly by a fixing device when closed.

[0013] Furthermore, the fixing device is a magnetic attraction device.

[0014] Furthermore, the protective door is made of transparent material, making it easy for operators to observe the working status of the execution module.

[0015] Furthermore, the transparent material is specifically high-strength polycarbonate.

[0016] Furthermore, the protective door is equipped with an ergonomically designed handle, the surface of which is treated with an anti-slip texture.

[0017] The protective door is positioned parallel to and / or perpendicular to the cutting surface of the cutting component and the axis of the rotating shaft. This design not only optimizes the space utilization of the equipment but also significantly improves operational safety and ease of maintenance. This arrangement allows operators a wider field of vision during equipment operation, enabling a more comprehensive observation of the cutting component's working status and facilitating real-time monitoring and adjustments. It also makes maintenance and adjustments easier for operators.

[0018] Polycarbonate (PC) is a high-performance engineering plastic widely used in applications requiring high-strength protection and transparent visibility due to its excellent impact resistance, high light transmittance, good heat resistance, and mechanical strength. Its light transmittance reaches 89%-90%, almost comparable to glass, ensuring operators can clearly observe the cutting process without opening protective doors. Simultaneously, polycarbonate has extremely high impact resistance, 250-300 times that of ordinary glass, effectively protecting operators from accidental injury in high-risk environments such as high-speed rotating slitting blades. Furthermore, polycarbonate has a wide operating temperature range, with a maximum short-term temperature of 140℃, a long-term operating temperature of 125℃, and a minimum application temperature of -100℃. Its heat distortion temperature is 135℃, meeting the stringent heat resistance requirements of industrial production. Polycarbonate also possesses excellent electrical insulation properties, maintaining stable electrical performance even in humid and high-temperature environments. In terms of chemical properties, polycarbonate exhibits excellent resistance to greases, lubricants, weak acids, weak alkalis, gasoline, water, and UV / weather exposure. Polycarbonate materials are easy to process, capable of being molded through injection molding, extrusion, and thermoforming. Its good machinability allows for easy cutting, drilling, and polishing. In this invention, the protective door utilizes these superior properties of polycarbonate to not only provide reliable protection for operators but also ensure real-time visual monitoring during equipment operation, thereby improving equipment safety and ease of operation.

[0019] The rotating shaft is forged from high-strength carbon structural steel. After being processed by a special heat treatment process, this material has both excellent strength and toughness, and can withstand the high-speed centrifugal force and complex alternating stress generated during rotation.

[0020] The fasteners can be secured magnetically. A magnet is installed inside the free end of the security door, and the second baffle adjacent to the free end is made of metal; the two can attract each other.

[0021] Alternatively, the fasteners can also employ various other fixing methods, such as mechanical locking (e.g., latches or bolts), hydraulic or pneumatic fixing, etc. Through the design of these multiple fixing methods, the fasteners can provide flexible and reliable security door fixing solutions according to different application scenarios and operational requirements.

[0022] The handle is installed on the outside of the safety door and features an ergonomic design with a non-slip textured surface. This design not only makes it easy for operators to open and close the safety door, but also reduces hand fatigue during prolonged operation and effectively prevents safety accidents caused by hand slippage.

[0023] This patent has the following beneficial effects:

[0024] This invention addresses the shortcomings of existing technologies by proposing a novel cutting blade protection device. Through the coordinated design of a single-end fixed rotating shaft and a transparent magnetic protective door, it reduces the constraint points of the rotating shaft, simplifies the mechanical structure, and provides ample space for the adjustment and maintenance of the slitting blade. Operators can quickly open and close the protective door without disassembling the complex structure, directly maintaining the slitting blade and significantly improving operational convenience and maintenance efficiency. The introduction of a high-strength transparent protective door physically isolates the dangerous cutting area while enabling full-process visual monitoring of abnormal conditions such as blade wear and misalignment, preventing production interruptions due to downtime for inspection. The protective door uses a magnetic fixing method combined with an ergonomically designed handle. This design balances safety and convenience during use. The transparent protective door allows for full-view visual monitoring of the slitting blade's working status. Operators can monitor the slitting blade's operation in real time without stopping the machine or disassembling the equipment, enabling them to promptly identify and resolve problems. This effectively reduces the product defect rate caused by blade malfunctions, improves product quality and production efficiency, and minimizes production interruptions caused by equipment downtime for inspection. Furthermore, this invention can be specifically modified and upgraded based on existing factory frames. While retaining the original frame's stable support function, it innovatively optimizes the core transmission and protective structures, reducing modification costs and achieving simultaneous improvements in production efficiency, safety, and product qualification rate.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0053] A cutting blade protection device, please refer to Figure 1 and Figure 3 The system includes a drive module, an execution module, and a protection module. The drive module comprises a drive component 110 and a base 120. Specifically, the drive component 110 is a motor, mounted on the base 120, providing stable rotational power. The base 120 is a metal frame used to fix the drive component 110 and the enclosure component 320, providing stable support for the entire device. The drive component 110 transmits power to the rotating shaft 220 via a synchronous belt or gear transmission system, ensuring that the rotating shaft 220 rotates smoothly at a constant speed. This transmission method not only improves transmission efficiency but also reduces operating noise, making the entire device operate more smoothly.

[0054] The execution module includes a bearing component 210, a rotating shaft component 220, and a cutting component 230. One end of the rotating shaft component 220 is mounted on the base 120 via the bearing component 210, allowing the rotating shaft component 220 to be rotatably connected to the base 120. The other end of the rotating shaft component 220 is connected to the cutting component, which is a high-speed rotating slitting blade used for precisely cutting the cigarette filter rod.

[0055] Optionally, the shaft is made of high-strength carbon structural steel, which is carefully forged. After being processed by a special heat treatment process, this material has both excellent strength and toughness, and can withstand the high-speed centrifugal force and complex alternating stress generated during rotation.

[0056] Optionally, the bearing component 210 can be a high-precision deep groove ball bearing, which is tightly connected to the base by high-strength bolts to ensure the rotational accuracy of the shaft component 220 and facilitate daily maintenance and replacement.

[0057] The protective module includes a protective door 310, a handle 311, and a barrier 320. See also... Figure 2 The enclosure component 320 is a semi-enclosed fixing structure located outside the execution module. Specifically, it can be a combination of multiple flat plates and / or irregularly shaped plates, which together with the protective door 310 form an open cavity to surround the cutting end of the execution module. The enclosure component 320 not only provides support for the protective door 310, but also enhances the structural stability of the entire protective module.

[0058] See Figure 2 The enclosure component 320 includes at least a first baffle 320a and a second baffle 320b, which are respectively disposed on both sides of the protective door. The protective door 310 has a flat plate structure, with one side of the protective door hinged to the adjacent first baffle 320a and the other side being a free end, thereby being able to be opened and closed and assembled onto the enclosure component 320.

[0059] Optionally, the protective door 310 is made of high-strength transparent polycarbonate material. Optionally, the first baffle 320a can be made of metal, transparent material, or any combination of the two to meet diverse needs for strength and visibility. The second baffle 320b, in the closed state, can be made of metal at the point where it engages with the protective door, and can be attracted to the magnets installed in the protective door 310 when the protective door 310 is closed.

[0060] The enclosure 320 is fixedly connected to the base 120 with high-strength bolts, ensuring that it can withstand greater mechanical forces and vibrations during equipment operation. During use, the enclosure 320 also effectively blocks debris and dust that may be generated during the high-speed rotation of the cutting parts, preventing them from splashing onto operators and protecting the environment around the equipment.

[0061] The shape and size design of the first baffle 320a and the second baffle 320b are highly flexible and can be any shape. The shape design of the protective door 310 can also be the same as that of the first baffle 320a and the second baffle 320b, ensuring the structural integrity and functionality of the entire protective module. The design of the above components only needs to meet the assembly requirements of conventional mechanical design, and there is no need to elaborate on the shape.

[0062] Polycarbonate (PC) is a high-performance engineering plastic widely used in applications requiring high-strength protection and transparent visibility due to its excellent impact resistance, high light transmittance, good heat resistance, and mechanical strength. Its light transmittance reaches 89%-90%, almost comparable to glass, ensuring operators can clearly observe the cutting process without opening protective doors. Simultaneously, polycarbonate has extremely high impact resistance, 250-300 times that of ordinary glass, effectively protecting operators from accidental injury in high-risk environments such as high-speed rotating slitting blades. Furthermore, polycarbonate has a wide operating temperature range, with a maximum short-term temperature of 140℃, a long-term operating temperature of 125℃, and a minimum application temperature of -100℃. Its heat distortion temperature is 135℃, meeting the stringent heat resistance requirements of industrial production. Polycarbonate also possesses excellent electrical insulation properties, maintaining stable electrical performance even in humid and high-temperature environments. In terms of chemical properties, polycarbonate exhibits excellent resistance to greases, lubricants, weak acids, weak alkalis, gasoline, water, and UV / weather exposure. Polycarbonate materials are easy to process, capable of being molded through injection molding, extrusion, and thermoforming. Its good machinability allows for easy cutting, drilling, and polishing. In this invention, the protective door utilizes these superior properties of polycarbonate to not only provide reliable protection for operators but also ensure real-time visual monitoring during equipment operation, thereby improving equipment safety and ease of operation.

[0063] The protective door 310 is designed to effectively isolate the slitting knife from the operator, preventing accidental injury, and also allows the operator to clearly observe the working status of the slitting knife. A fixing member 330 is provided at the free end of the protective door 310, which securely fixes the door in the closed position when it is closed, preventing accidental opening due to vibration.

[0064] Specifically, the protective door is arranged parallel to the cutting surface of the cutting component and / or perpendicular to the axis of the rotating shaft. This design not only optimizes the space utilization of the equipment but also significantly improves operational safety and maintenance convenience. The parallelism of the protective door to the cutting surface of the cutting component allows operators to more intuitively observe the working status of the cutting component during equipment operation, promptly identifying abnormalities and thus improving equipment safety and yield. The perpendicularity of the protective door to the axis of the rotating shaft provides operators with a wider field of vision, allowing for a more comprehensive observation of the cutting component's working status, facilitating real-time monitoring and adjustment. Furthermore, when open, the protective door fully exposes the cutting component, enabling operators to perform maintenance and adjustments more conveniently and intuitively.

[0065] Specifically, the fastener 330 can be fixed by magnetic attraction. A magnet is installed in the free end of the protective door, and the second baffle 320b adjacent to the free end is made of metal, and the two can attract each other.

[0066] Alternatively, the fastener 330 can also employ various other fastening methods, such as mechanical locking (e.g., latches or bolts), hydraulic or pneumatic fastening, etc. Through these multiple fastening methods, the fastener 330 can provide flexible and reliable security door fastening solutions tailored to different application scenarios and operational requirements.

[0067] The handle 311 is installed on the outside of the protective door 310. It features an ergonomic design and a non-slip textured surface. This design not only makes it easy for operators to open and close the protective door, but also reduces hand fatigue during prolonged operation and effectively prevents safety accidents caused by hand slippage.

[0068] Working principle

[0069] Before starting the cigarette filter rod slitting operation, the operator first presets key process parameters such as the cutting speed and filter rod slitting length on the equipment control panel. After the equipment starts, the drive unit immediately begins to operate, transmitting power stably to the rotating shaft via a high-precision synchronous belt. Synchronous belt drive has advantages such as high transmission efficiency, smooth operation, and low noise, ensuring that the rotating shaft drives the cutting part to rotate at a constant speed, quickly reaching the preset working speed. At this time, the upstream filter rod conveying equipment begins to orderly convey the continuously formed cigarette filter rods to the feed inlet. The filter rods are neatly arranged along the positioning grooves on a specially designed conveyor belt, entering the cutting end with a precise posture.

[0070] During the cigarette filter rod slitting process, the rotating shaft rotates at high speed under the drive of the drive component, which in turn drives the cutting component installed at the other end of the shaft to rotate synchronously. The cigarette filter rods to be slit are conveyed to the cutting position of the slitting blade by the action of the conveying device. The slitting blade cuts the cigarette filter rods according to the set dimensions by the cutting force generated by the high-speed rotation.

[0071] During equipment operation, operators can observe the cutting process in real time through the protective door, including its rotation status, cutting effect, and any abnormal wear or misalignment. If any abnormalities are found, such as uneven cuts or dimensional deviations in the cut filter rods, the execution module needs maintenance or adjustment. In actual operation, the operator holds handle 311 and gently applies force to overcome the fixing force (such as magnetic attraction) to open the protective door 310. Due to the single-end fixed shaft design, the operator can directly access the slitting blade after the protective door is opened, eliminating the need for complex disassembly. The open door also provides ample operating space, making blade adjustment and maintenance more convenient and efficient. After adjustment, the operator closes the protective door 310 again, securing the fixing force 330 and ensuring equipment safety during operation.

[0072] Industrial applicability:

[0073] This invention proposes a cutting blade protection device. Through the coordinated design of a single-end fixed rotating shaft and a transparent magnetic protective door, the constraint points of the rotating shaft are reduced, the mechanical structure is simplified, and ample space is reserved for the adjustment and maintenance of the slitting blade. Operators can quickly open and close the protective door without disassembling the complex structure, directly maintaining the slitting blade, significantly improving operational convenience and maintenance efficiency. The introduction of a high-strength transparent protective door physically isolates the dangerous cutting area while enabling full-process visual monitoring of abnormal states such as slitting blade wear and misalignment, eliminating production interruptions caused by machine downtime for inspection, and achieving full-view visual monitoring of the slitting blade's working status. The system allows operators to monitor the slitting blade's operation in real time without stopping or disassembling the equipment, enabling timely detection and resolution of problems. This effectively reduces product defect rates caused by blade malfunctions, improving product quality and production efficiency. The protective door uses a magnetic fixing method, combined with an ergonomically designed handle, balancing safety and convenience during use. Furthermore, this invention can be specifically modified and upgraded based on existing factory frames. While retaining the original frame's stable support function, it innovatively optimizes the core transmission and protective structures, reducing modification costs and achieving simultaneous improvements in production efficiency, safety, product qualification rate, and compatibility.
