Description

Technical Field

[0001] This invention relates to the field of aluminum processing technology, specifically to a device and method for detecting and preventing blockage in a conveying pipe for waste material from a coiling machine. Background Technology

[0002] In the aluminum processing industry, aluminum chips (usually in the form of uneven, thin strips and / or short fragments) generated by the cutting edge of the coiling machine are typically transported to the hopper of the baling machine via a long pipeline by a blower, where they are compressed and packaged before being smelted and recycled.

[0003] Because the conveying pipeline is long and the air duct is directly connected to the baling machine's hopper, the existing pipeline system lacks effective detection and feedback devices when the hopper becomes blocked. Operators cannot detect the blockage in time, causing aluminum shavings to accumulate along the pipeline and eventually back up, blocking the coiling machine and causing equipment downtime. Clearing the blocked pipeline requires high-altitude work, and even with eight people working simultaneously, it takes at least 10 hours to complete the task. This poses low safety risks and severely impacts both production efficiency and operational safety.

[0004] Patent CN120172113A discloses a pipe anti-clogging detection device and method. It determines whether the pipe outlet is blocked by detecting the rotational speed of the drive shaft during passive belt operation, and then transports the blocked aluminum shavings during active belt operation. While this device achieves pipe anti-clogging detection and unblocking, it still has significant shortcomings in practical applications: First, because the conveying pipes are usually long, the device needs to be installed inside the pipe, making installation and maintenance cumbersome; second, this solution can only determine whether the pipe is blocked, but cannot quickly locate the blockage.

[0005] Therefore, the present invention provides a detection device and method for preventing blockage in the conveying pipeline of waste material from the edge cutting of a winding machine, in order to solve the above-mentioned problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the existing defects and provide a detection device and method for preventing blockage in the conveying pipe of the winding machine edge trimming waste. By using toothed rings arranged at intervals on the pipe and a servo motor that can obtain output torque parameters, the difficulty of installation and maintenance is reduced. It can accurately locate the blockage section, and can also achieve online location detection and unblocking of blockage by using the cooperation of moving and fixed blades to cut back and push the waste material axially back and forth with the push rod. It eliminates the need for long-term manual high-altitude operation, significantly improves production safety and conveying efficiency, and can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a detection device and method for preventing blockage in a conveying pipe for edge trimming waste in a coiler, comprising cross-arranged air ducts and a toothed ring. The toothed ring is rotatably mounted on two adjacent air ducts. A moving blade is provided on the inner side of the toothed ring near the feed inlet. A fixed blade is provided on the inner wall of the air duct near the moving blade, which is in contact with the moving blade. A servo motor is provided on the outer periphery of the air duct. A gear meshing with the toothed ring is provided on the output shaft of the servo motor. The servo motor is electrically connected to an external controller. The output torque parameters of the servo motor are obtained through the external controller, and the presence of blockage inside the pipe is determined based on the changes in the output torque parameters. When a blockage is detected, the servo motor drives the toothed ring to rotate the moving blade reciprocally relative to the fixed blade, cutting the blockage material.

[0008] As a preferred embodiment of the present invention, the fixed blade is provided with a cone extending away from the moving blade to guide the diffusion of waste material.

[0009] As a preferred embodiment of the present invention, the moving blade is provided with a screw that penetrates the fixed blade and extends into the interior of the cone. A threaded cylinder that is threadedly connected to the screw is movably inserted inside the cone. A push rod is installed at the end of the threaded cylinder away from the screw. When the moving blade rotates forward, the screw drives the threaded cylinder and the push rod to move axially away from the moving blade. When the moving blade rotates in reverse, the threaded cylinder and the push rod move axially towards the moving blade, causing the push rod to push the waste material towards the discharge port.

[0010] As a preferred embodiment of the present invention, a guide rod is installed at one end of the push rod near the cone, which is movably inserted into the interior of the cone.

[0011] A detection method for an anti-clogging detection device for a waste conveying pipe of a winding machine, characterized by comprising the following steps:

[0012] S1. Multiple detection devices are set at intervals along the conveying direction on the air duct. When the high-pressure air conveys the cutting waste through the air duct, the corresponding servo motors are started sequentially from the detection device near the discharge end to the detection device near the feed end by the external controller, and the output torque parameters of each servo motor are obtained in real time.

[0013] S2. When the output torque parameter of the servo motor of a certain detection device exceeds the preset threshold, while the output torque parameter of the servo motor of the detection device located downstream of its discharge direction is within the normal range, it is determined that there is a blockage at the current location of the detection device.

[0014] S3. The external controller controls the servo motor to drive the gear ring to drive the moving blade to rotate forward and reverse within a certain angle range. The moving blade and the fixed blade work together to cut the blockage waste.

[0015] S4. During the forward rotation of the moving blade, the screw drives the threaded cylinder and the push rod to move axially away from the moving blade; during the reverse rotation of the moving blade, the threaded cylinder and the push rod return to their original positions towards the moving blade, and the push rod pushes the cut waste material towards the outlet, while the moving blade and the fixed blade continue to cut the waste material.

[0016] S5. Repeat steps S3 to S4 until the output torque parameter returns to the normal threshold range, indicating that the blockage has been cleared.

[0017] As a preferred embodiment of the present invention, in S3, the angle range is from 180° to 720°.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The anti-blocking detection device and detection method for the waste conveying pipeline of the winding machine in the example of the present invention, by setting a toothed ring driven by a servo motor on the air duct and configuring a moving blade and a fixed blade that fit together, and using an external controller to obtain the change of the output torque parameter of the servo motor to judge the blockage, realizes non-contact, high-sensitivity online blockage detection, and avoids the blockage of the entire pipeline and equipment downtime due to the blockage not being detected in time.

[0020] 2. The anti-blocking detection device and detection method for the waste conveying pipeline of the winding machine in this invention can accurately locate the specific section where the blockage occurs by sequentially starting the servo motors of each detection device from the discharge end to the feed end and comparing the torque parameters of adjacent detection points. This solves the problem of difficulty in quickly identifying blockage points in long pipelines and greatly shortens the fault handling time.

[0021] 3. The anti-blocking detection device and detection method for the waste conveying pipeline of the winding machine in the example of the present invention, when a blockage is detected, controls the servo motor to drive the moving blade to reciprocate in a certain angle range, so that the moving blade and the fixed blade repeatedly cut the blockage material, forming a composite unblocking action of "cutting + reciprocating", which has high unblocking efficiency and can avoid material entanglement or secondary blockage caused by unidirectional rotation.

[0022] 4. The anti-clogging detection device and detection method for the waste conveying pipe of the coiling machine in the example of the present invention, by setting a cone extending away from the moving blade on the fixed blade, plays a role in diffusing and guiding aluminum chips entering the cutting area, preventing material from accumulating at the inlet of the moving blade and the fixed blade, thereby improving cutting efficiency and unblocking success rate.

[0023] 5. The anti-clogging detection device and detection method for the waste conveying pipeline of the coiling machine, as exemplified by the present invention, converts the rotational motion of the moving blade into the axial reciprocating motion of the pushing rod by setting a screw, a threaded cylinder and a pushing rod. When the moving blade rotates forward, the pushing rod pushes the cut waste material towards the outlet direction. When it rotates in reverse, it resets and continues cutting, realizing the linkage unblocking of "cutting and pushing at the same time", which significantly reduces the dependence on the conveying capacity of the fan, and is especially suitable for long-distance, easily clogged aluminum chip conveying pipelines.

[0024] 6. The anti-blocking detection device and detection method for the waste conveying pipeline of the winding machine, as exemplified by the present invention, reduces the difficulty of installation and maintenance by using toothed rings spaced apart on the pipeline and a servo motor that can acquire output torque parameters. It can accurately locate the blockage section, and can also achieve online location detection and unblocking of blockage by using moving and fixed blades to reciprocate cut and pushing the waste material axially back and forth using a push rod. It eliminates the need for long-term manual high-altitude operations, significantly improving production safety and conveying efficiency. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-4This invention provides a technical solution: a detection device and method for preventing blockage in a conveying pipe for edge trimming waste in a winding machine, comprising cross-arranged air ducts 1 and gear rings 2. The gear rings 2 are rotatably mounted on two adjacent air ducts 1. A movable blade 4 is provided on the inner side of the gear ring 2 near the feed inlet. A fixed blade 5, which fits against the movable blade 4, is provided on the inner wall of the air duct 1 near the movable blade 4. A servo motor 3 is provided on the outer periphery of the air duct 1. A gear 31 meshing with the gear ring 2 is provided on the output shaft of the servo motor 3. The servo motor 3 is electrically connected to an external controller, and the external controller obtains the signal from the servo motor 3. The system outputs torque parameters and determines whether there is a blockage inside the pipe based on changes in these parameters. When a blockage is detected, the servo motor 3 drives the gear ring 2 to rotate the moving blade 4 relative to the fixed blade 5, cutting the blockage material. By setting the gear ring 2 driven by the servo motor 3 on the duct 1 and configuring the moving blade 4 and fixed blade 5 that fit together, and using an external controller to obtain changes in the output torque parameters of the servo motor 3 to determine the blockage, non-contact, high-sensitivity online blockage detection is achieved, avoiding blockage of the entire pipe and equipment downtime due to untimely blockage detection.

[0032] The present invention can also accurately locate the specific section where the blockage occurs by sequentially activating the servo motors 3 of each detection device from the discharge end to the feed end and comparing the torque parameters of adjacent detection points, thus solving the problem of difficulty in quickly diagnosing blockages in long pipelines and significantly shortening the fault handling time.

[0033] Furthermore, the fixed blade 5 is provided with a cone 51 extending away from the moving blade 4 to guide the diffusion of waste material; by providing a cone 51 extending away from the moving blade 4 on the fixed blade 5, the aluminum chips entering the cutting area are diffused and guided, preventing the material from accumulating at the entrance of the moving blade 4 and the fixed blade 5, thereby improving the cutting efficiency and the success rate of clearing the blockage.

[0034] Furthermore, the moving blade 4 is equipped with a screw 41 that penetrates the fixed blade 5 and extends into the interior of the cone 51. A threaded cylinder 6, which is threadedly connected to the screw 41, is movably inserted inside the cone 51. A push rod 7 is installed at the end of the threaded cylinder 6 away from the screw 41. When the moving blade 4 rotates forward, the screw 41 drives the threaded cylinder 6 and the push rod 7 to move axially away from the moving blade 4. When the moving blade 4 rotates in reverse, the threaded cylinder 6 and the push rod 7 move axially towards the moving blade 4, causing the push rod 7 to push the waste material towards the discharge port. By setting up the screw 41, the threaded cylinder 6, and the push rod 7, the rotational motion of the moving blade 4 is converted into the axial reciprocating motion of the push rod 7. When the moving blade 4 rotates forward, the push rod 7 pushes the cut waste material towards the outlet. When it rotates in reverse, it resets and continues cutting, realizing the linkage of "cutting and pushing at the same time" to clear blockages. This significantly reduces the dependence on the conveying capacity of the blower and is especially suitable for long-distance, easily blocked aluminum chip conveying pipelines.

[0035] Furthermore, a guide rod 71 is installed at the end of the push rod 7 near the truncated cone 51, which is movably inserted into the truncated cone 51 to guide the push rod 7 and prevent the push rod 7 from rotating.

[0036] A detection method for an anti-clogging detection device for a waste conveying pipe of a winding machine, characterized by comprising the following steps:

[0037] S1. Multiple detection devices are set at intervals along the conveying direction on the air duct 1. When the high-pressure air conveys the cutting waste through the air duct 1, the corresponding servo motor 3 is started sequentially from the detection device near the discharge end to the detection device near the feed end by the external controller, and the output torque parameters of each servo motor 3 are obtained in real time.

[0038] S2. When the output torque parameter of the servo motor 3 of a certain detection device exceeds the preset threshold, while the output torque parameter of the servo motor 3 of the detection device located downstream of its discharge direction is within the normal range, it is determined that there is a blockage at the current location of the detection device.

[0039] S3. The external controller controls the servo motor 3 to drive the gear ring 2 to drive the moving blade 4 to rotate forward and reverse within a certain angle range. The moving blade 4 cooperates with the fixed blade 5 to cut the blocked waste material.

[0040] S4. During the forward rotation of the moving blade 4, the screw 41 drives the threaded cylinder 6 and the push rod 7 to move axially away from the moving blade 4. During the reverse rotation of the moving blade 4, the threaded cylinder 6 and the push rod 7 return to their original positions and move closer to the moving blade 4. The push rod 7 pushes the cut waste material towards the outlet, while the moving blade 4 and the fixed blade 5 continue to cut the waste material.

[0041] S5. Repeat steps S3 to S4 until the output torque parameter returns to the normal threshold range, indicating that the blockage has been cleared.

[0042] Furthermore, in S3, a certain angle range is 180° to 720°. The forward and reverse rotation angle range of the moving blade 4 is set to 180° to 720°, which can ensure that the material is fully cut and pushed in each reciprocating motion, while avoiding ineffective power consumption or mechanical wear due to excessive rotation, thus achieving an optimized balance between dredging efficiency and energy consumption.

[0043] This invention reduces the difficulty of installation and maintenance by using toothed rings 2 spaced apart on the pipeline and servo motors 3 that can acquire output torque parameters. It can accurately locate blocked sections and can also achieve online location detection and unblocking of blockages by using moving blades 4 and fixed blades 5 to reciprocate cutting and pushing waste material axially with push rods 7. This eliminates the need for long-term manual high-altitude operations and significantly improves production safety and conveying efficiency.

[0044] All parts not disclosed in this invention are prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
