A front pressure roller shaft 14 and a rear pressure roller shaft 15 are movably installed on the lifting frame 4. A dust collection device 16 and a dust collection box 17 are fixedly installed on the lifting frame 4. The dust collection box 17 has an elongated dust collection port 18, which is located on one side of the front pressure roller shaft 14. The lifting frame 4 is fixedly equipped with a protective cover 19, the protective cover 19 is provided with an inspection port 20, the inspection port 20 is fixedly equipped with a side cover 21, and the side cover 21 is fixedly equipped with a handle 22. The grinding roller 9 includes a main roller shaft 23 and a detachable cylindrical grinding wheel 24.

[0018] Through the above technical solution, this utility model uses a conveyor belt 2 to transport workpieces in batches and pass them through the grinding device 7. The motor 8 drives the grinding roller 9 to rotate in the opposite direction to the conveyor belt 2. The front pressure roller shaft 14 and the pressure roller shaft are located on both sides of the grinding roller 9, pressing the passing workpieces together, which facilitates the grinding machine to remove burrs from the workpieces. The distance between the grinding roller 9 and the conveyor belt 2 can be adjusted by the lifting machine 5 and the lifting frame 4, which facilitates the grinding of workpieces of different sizes. The workpieces are transported and ground in batches through the conveyor belt 2 without the need for manual fixing, thus improving processing efficiency.

[0019] Example 2:

[0020] In this embodiment, the frame 1 is fixedly mounted with the conveyor belt 2. The frame 1 is movably mounted with the lifting frame 4 via the optical shaft 3. The frame 1 is fixedly mounted with the lifting machine 5. The lifting machine 5 is driven and connected to the lifting frame 4 via the lead screw 6. The lifting frame 4 is fixedly mounted with the grinding device 7. The grinding device 7 includes a motor 8 and a grinding roller 9. The motor 8 drives and connects to the grinding roller 9. The other end of the grinding roller 9 is fixedly connected to the lifting frame 4 via the quick-release assembly 10. The quick-release assembly 10 includes a fixed seat 11 and a bearing assembly 12. The fixed seat 11 is movably connected to the grinding roller 9 via the bearing assembly 12. The fixed seat 11 is fixedly connected to the lifting frame 4 via the fastening bolt 13. The lifting frame 4 is movably mounted with the front pressure roller shaft 14 and the rear pressure roller shaft 15.

[0021] In this embodiment, the frame 1, serving as the basic support structure of the entire device, is welded from metal materials to ensure overall rigidity and stability. The conveyor belt 2 is installed on the upper part of the frame 1 for continuously transporting the hardware workpieces to be processed. The conveyor belt 2 is driven by a motor 8, and its conveying speed can be adjusted according to actual processing needs to adapt to the processing rhythm of different workpieces. The surface of the conveyor belt 2 is made of wear-resistant material to extend its service life and reduce workpiece slippage during transport.

[0022] The lifting frame 4 is movably connected to the machine frame 1 via an optical axis 3, which is arranged vertically, allowing the lifting frame 4 to move up and down along this axis. The lifting mechanism 5 is fixed to the machine frame 1 and connected to the lifting frame 4 via a lead screw 6. The lifting mechanism 5 is electrically or hydraulically driven, and the precise lifting of the lifting frame 4 is achieved by controlling the rotation of the lead screw 6. This design allows the operator to adjust the height of the grinding device 7 as needed, thus accommodating the processing requirements of workpieces of different thicknesses or sizes.

[0023] The grinding device 7 is mounted on the lifting frame 4 and includes a motor 8 and a grinding roller 9. The motor 8 directly drives the grinding roller 9 to rotate via a belt or coupling. The surface of the grinding roller 9 is covered with a rough material, such as sandpaper or abrasive stone, to remove burrs from the workpiece surface. The rotation direction of the grinding roller 9 is opposite to the movement direction of the conveyor belt 2, which increases the relative grinding speed and improves grinding efficiency and quality. The motor 8 can adjust its speed according to the workpiece material and the degree of burr formation to achieve the best grinding effect.

[0024] The quick-release assembly 10 secures one end of the grinding roller 9 to the lifting frame 4 while allowing the grinding roller 9 to rotate freely. The quick-release assembly 10 includes a mounting base 11 and a bearing assembly 12. The mounting base 11 is connected to the lifting frame 4 via fastening bolts 13, facilitating quick disassembly and replacement of the grinding roller 9. The bearing assembly 12 is installed within the mounting base 11, supporting the end of the grinding roller 9, reducing friction, and ensuring smooth rotation. This design makes maintenance and replacement of the grinding roller 9 simple and quick, reducing downtime.

[0025] The front clamping roller shaft 14 and the rear clamping roller shaft 15 are movably mounted on the lifting frame 4, located on the front and rear sides of the grinding roller 9, respectively. The front clamping roller shaft 14 is used to clamp the workpiece before it enters the grinding area, preventing the workpiece from shifting or jumping during transport. The rear clamping roller shaft 15 is used to maintain clamping after the workpiece leaves the grinding area, ensuring the continuity and stability of the grinding process. The clamping force of the clamping roller shafts can be adjusted by springs or pneumatic devices to adapt to different workpiece materials and shapes.

[0026] During operation, the metal workpiece is continuously conveyed by the conveyor belt 2 to the area below the grinding device 7. The lifting platform 5 adjusts the position of the lifting frame 4 according to the workpiece height, ensuring that the grinding roller 9 maintains appropriate contact pressure with the workpiece surface. The motor 8 drives the grinding roller 9 to rotate at high speed, cooperating with the front pressure roller shaft 14 and the rear pressure roller shaft 15 to uniformly remove burrs from the workpiece surface. Due to the continuous movement of the conveyor belt 2 and the stabilizing effect of the pressure roller shafts, the workpiece can be automatically ground without manual fixation, significantly improving processing efficiency and consistency.

[0027] This device integrates conveying, lifting, grinding, and pressing functions, achieving automated and efficient burr removal for hardware products. It is suitable for mass production environments and reduces manual intervention and operating costs.

[0028] Example 3:

[0029] In this embodiment, the frame 1 is fixedly mounted with the conveyor belt 2. A lifting frame 4 is movably mounted on the frame 1 via an optical shaft 3. A lifting mechanism 5 is fixedly mounted on the frame 1. The lifting mechanism 5 is driven and connected to the lifting frame 4 via a lead screw 6. A grinding device 7 is fixedly mounted on the lifting frame 4. The grinding device 7 includes a motor 8 and a grinding roller 9. The motor 8 drives and connects to the grinding roller 9. The other end of the grinding roller 9 is fixedly connected to the lifting frame 4 via a quick-release assembly 10. The quick-release assembly 10 includes a fixed seat 11 and a bearing assembly 12. The fixed seat 11 is movably connected to the grinding roller 9 via the bearing assembly 12. The fixed seat 11 is fixedly connected to the lifting frame 4 via fastening bolts 13. A front pressure roller shaft 14 and a rear pressure roller shaft 15 are movably mounted on the lifting frame 4. A dust collection device 16 and a dust collection box 17 are fixedly mounted on the lifting frame 4. The dust collection box 17 has an elongated dust collection port 18, located on one side of the front pressure roller shaft 14. As the motor 8 drives the grinding roller 9 to rotate in the opposite direction to the conveyor belt 2, the debris will splash towards the position of the front pressure roller shaft 14. The elongated dust suction port 18 is located on one side of the front pressure roller shaft 14 to facilitate the suction of debris.

[0030] During operation, the conveyor belt 2 continuously transports the metal workpieces to the grinding device 7 area. The lifting platform 5 drives the lifting frame 4 to move up and down along the optical axis 3 via the lead screw 6, thereby adjusting the distance between the grinding roller 9 and the conveyor belt 2 to accommodate workpieces of different thicknesses or sizes. When the workpiece enters the grinding area, the front pressure roller shaft 14 and the rear pressure roller shaft 15 are located on both sides of the grinding roller 9, working together to press the workpiece firmly onto the conveyor belt 2, ensuring the workpiece remains stable during grinding and preventing displacement or vibration from affecting the grinding effect. The motor 8 drives the grinding roller 9 to rotate at high speed, and the rotation direction is opposite to the movement direction of the conveyor belt 2. This relative motion enhances grinding efficiency and effectively removes burrs from the workpiece surface.

[0031] During the grinding process, friction and impact between the grinding roller 9 and the workpiece generate a large amount of metal shavings and dust. These shavings are splashed forward along the roller shaft 14 due to the reverse rotation of the grinding roller 9. The dust collection device 16 promptly collects these shavings through the elongated suction port 18 of the dust collection box 17. The design of the elongated suction port 18 allows it to cover a wider area, ensuring that shavings are captured immediately after generation, preventing them from spreading into the working environment, and reducing cleaning burden and maintenance needs. The dust collection device 16 temporarily stores the collected shavings in the dust collection box 17 for subsequent processing or cleaning.

[0032] The quick-release assembly 10 supports the rotation of the grinding roller 9 via the fixed base 11 and bearing assembly 12, and facilitates the quick installation and removal of the grinding roller 9 via the fastening bolts 13, making it easy to replace or maintain the grinding roller 9. The entire device, through an automated conveying and clamping mechanism, enables continuous batch processing of hardware workpieces without manual intervention to fix the workpieces, significantly improving processing efficiency and consistency. The adjustable function of the lifting frame 4 further enhances the adaptability of the device, enabling it to handle workpieces of various specifications, improving the equipment's versatility and practicality.

[0034] In this embodiment, the frame 1 is fixedly mounted with the conveyor belt 2. A lifting frame 4 is movably mounted on the frame 1 via an optical shaft 3. A lifting mechanism 5 is fixedly mounted on the frame 1. The lifting mechanism 5 is driven and connected to the lifting frame 4 via a lead screw 6. A grinding device 7 is fixedly mounted on the lifting frame 4. The grinding device 7 includes a motor 8 and a grinding roller 9. The motor 8 drives and connects to the grinding roller 9. The other end of the grinding roller 9 is fixedly connected to the lifting frame 4 via a quick-release assembly 10. The quick-release assembly 10 includes a fixed base 11 and a bearing assembly 12. The fixed base 11 is movably connected to the grinding roller 9 via the bearing assembly 12. The fixed base 11 is fixedly connected to the lifting frame 4 via fastening bolts 13. A front pressure roller shaft 14 and a rear pressure roller shaft 15 are movably mounted on the lifting frame 4. A protective cover 19 is fixedly mounted on the lifting frame 4. The protective cover 19 has an inspection port 20. A side cover 21 is fixedly mounted on the inspection port 20, and a handle 22 is fixedly mounted on the side cover 21. The inspection port 20 is used for maintaining the grinding roller 9, replacing the detachable cylindrical grinding wheel 24 of the grinding roller 9, etc.

[0035] The protective cover 19 is designed to provide safety protection, preventing operators from coming into contact with the high-speed rotating grinding roller 9 during equipment operation, thereby reducing the risk of accidental injury. The protective cover 19 is securely fixed to the lifting frame 4 by welding or bolting, ensuring that it will not loosen or shift during equipment operation. The protective cover 19 is typically made of a metal material, such as steel plate or aluminum alloy, to provide sufficient strength and durability while withstanding the vibrations and impacts that may occur during grinding. The shape and size of the protective cover 19 are designed to completely cover the grinding roller 9 and its related components, ensuring that all rotating parts are effectively isolated during equipment operation.

[0036] The access port 20 is located on the side of the protective cover 19, and its position is carefully designed to allow operators easy access to the grinding roller 9 for maintenance and replacement operations. The access port 20 is large enough to allow operators to reach in tools or hands to make necessary adjustments or replacements. The edges of the access port 20 are typically smoothed to prevent injury to operators from sharp edges. The side cover 21 is secured to the access port 20 by hinges or bolts, ensuring a complete seal when closed to prevent dust, debris, or other foreign objects from entering the protective cover 19 and affecting the normal operation of the equipment. The side cover 21 is also designed for easy opening and closing, allowing for quick operation when rapid maintenance is required.

[0037] The handle 22 is securely mounted on the side cover 21, and its position and shape are ergonomically designed for easy gripping and operation. The handle 22 is typically made of metal or high-strength plastic to ensure durability and reliability. The handle 22 may be installed by welding, bolting, or riveting to ensure it does not loosen or fall off during frequent use. Through the handle 22, the operator can easily open or close the side cover 21 to access the access port 20 for maintenance. The surface of the handle 22 may be treated with a non-slip coating to provide a better grip and reduce the risk of slippage during operation.

[0038] The main function of the access port 20 is to facilitate routine maintenance of the grinding roller 9, such as checking the wear condition of the grinding roller 9, cleaning the dust accumulated on the surface of the grinding roller 9, or replacing the detachable cylindrical grinding wheel 24. The detachable cylindrical grinding wheel 24 is a key component in the grinding device 7, which is connected to the grinding roller 9 via a quick-release assembly 10, allowing for quick replacement when worn or damaged. The quick-release assembly 10 includes a mounting base 11 and a bearing assembly 12. The mounting base 11 is movably connected to the grinding roller 9 via the bearing assembly 12 and is fixed to the lifting frame 4 by fastening bolts 13. This design allows the operator to simply loosen the fastening bolts 13 to remove the grinding roller 9 and its assembly from the lifting frame 4 when changing the grinding wheel, and then perform replacement or maintenance through the access port 20.

[0039] During operation, when it is necessary to replace the detachable cylindrical grinding wheel 24, the operator first stops the equipment to ensure that the grinding roller 9 has completely stopped rotating. Then, the side cover 21 is opened through the handle 22 to expose the access port 20. The operator can access the grinding roller 9 through the access port 20, use a tool to loosen the fastening bolts 13 of the quick-release assembly 10, and remove the grinding roller 9 from the mounting base 11. After disassembly, the operator can remove the old cylindrical grinding wheel and install the new grinding wheel. After installation, the grinding roller 9 is re-secured to the mounting base 11 and connected to the lifting frame 4 using the fastening bolts 13. Finally, the side cover 21 is closed to ensure the access port 20 is sealed, and then the equipment is restarted for testing.

[0040] The combined design of the protective cover 19, access port 20, side cover 21, and handle 22 not only improves equipment safety but also significantly enhances maintenance efficiency. Through the access port 20, operators can quickly complete maintenance tasks without completely disassembling the protective cover 19 or moving other components, reducing equipment downtime. Furthermore, this design helps maintain a clean working environment, preventing debris and dust generated during grinding from spreading to the surrounding area, thereby improving working conditions and meeting safety production standards.

[0041] Example 5:

[0042] The grinding roller 9 in this embodiment includes a main roller shaft 23 and a detachable cylindrical grinding wheel 24. During maintenance, there is no need to replace the main roller shaft 23, thereby reducing maintenance costs. This embodiment details the specific structure of the grinding roller 9 and its working principle and operation in the burr removal device.

[0043] In this embodiment, the grinding roller 9 consists of a main roller shaft 23 and a detachable cylindrical grinding wheel 24. The main roller shaft 23 is a cylindrical metal shaft, typically made of high-strength steel to ensure stability and durability during high-speed rotation. One end of the main roller shaft 23 is connected to the output shaft of the motor 8 via a coupling and is driven to rotate by the motor 8. The other end of the main roller shaft 23 is fixedly connected to the lifting frame 4 via a quick-release assembly 10. The quick-release assembly 10 includes a fixed seat 11 and a bearing assembly 12. The fixed seat 11 is movably connected to the main roller shaft 23 via the bearing assembly 12, allowing the main roller shaft 23 to rotate freely. At the same time, the fixed seat 11 is fixed to the lifting frame 4 by fastening bolts 13, facilitating quick disassembly and installation. The detachable cylindrical grinding wheel 24 is a sleeve-shaped grinding element made of abrasive and binder, with a uniform grit distribution and appropriate hardness to effectively remove burrs from the surface of hardware products. The inner diameter of the detachable cylindrical grinding wheel 24 matches the outer diameter of the main roller shaft 23, and it is fixed to the main roller shaft 23 by interference fit or keyway connection. This design allows only the cylindrical grinding wheel to be removed and replaced when the grinding wheel is worn or damaged, without replacing the entire main roller shaft 23, thus significantly reducing maintenance time and cost.

[0044] During operation, the deburring device transports hardware products in batches to the grinding position via conveyor belt 2. Conveyor belt 2 is driven by motor 8 and runs at a constant speed to ensure continuous workpiece feeding. When the workpiece reaches below the grinding device 7, the lifting platform 5 drives the lifting frame 4 to descend via screw 6, bringing the grinding roller 9 into contact with the workpiece surface. Motor 8 starts, driving the grinding roller 9 to rotate at high speed in the opposite direction to the conveyor belt 2, increasing the grinding effect and cleaning efficiency. Front and rear pressure roller shafts 14 and 15 are located on either side of the grinding roller 9, respectively. Pressure is applied via springs or pneumatic devices to press the workpiece firmly onto the conveyor belt 2, preventing displacement or bounce during grinding and ensuring the uniformity and integrity of the deburring process.

[0045] The working principle of the grinding roller 9 is based on grinding. The outer surface of the detachable cylindrical grinding wheel 24 contacts the workpiece, removing burrs, flash, or irregular protrusions from the edges and surfaces of the workpiece through rotational friction. Since the grinding wheel is composed of abrasive particles, these particles cut the metal surface under pressure, achieving fine cleaning. The main roller shaft 23 provides stable support and power transmission, ensuring smooth rotation of the grinding wheel without vibration or deviation, thereby improving grinding accuracy and workpiece quality. The height of the lifting frame 4 can be adjusted by the lifting platform 5 to accommodate hardware products of different thicknesses or sizes, such as thin plates, stamped parts, or castings, ensuring that the contact pressure between the grinding roller 9 and the workpiece is maintained, avoiding over-grinding or under-cleaning.

[0046] In terms of maintenance, when the detachable cylindrical grinding wheel 24 becomes worn or clogged due to long-term use, the operator can loosen the fastening bolts 13 of the quick-release assembly 10 and remove the mounting base 11 to easily remove and replace the grinding wheel. This eliminates the need to disassemble the main roller 23 or other complex components, simplifying the maintenance process and reducing downtime. After replacement, simply reinstall the grinding wheel and tighten the bolts 13 to restore normal operation of the unit. This modular design not only reduces spare parts costs, as only the cylindrical grinding wheel is required instead of the entire roller assembly, but also improves the reliability and service life of the unit.

[0047] Overall, this embodiment achieves efficient and low-cost burr removal through the combination of the main roller 23 and the detachable cylindrical grinding wheel 24, making it suitable for large-scale production environments. It solves the problem of low efficiency in traditional manual grinding, improves processing efficiency and consistency through automated conveying and clamping mechanisms, and is easy to maintain, meeting the needs of modern manufacturing for equipment economy and practicality.
