Description

Technical Field

[0001] This utility model relates to the field of aluminum guide roller processing technology, and in particular to a loading and unloading device for processing large aluminum guide rollers. Background Technology

[0002] Aluminum guide rollers, typically made of aluminum alloy, are cylindrical components that operate by rotation. They serve functions such as support, guidance, conveying, and tensioning in various mechanical equipment, and are crucial components in the production processes of many industries. In the production and processing of large aluminum guide rollers, loading and unloading devices are usually used for the loading and unloading processes.

[0003] Large aluminum guide rollers are typically large in size and weight. During transport on a feeding conveyor, the aluminum guide rollers are prone to shifting during movement, which can lead to inaccurate workpiece positioning, processing errors, and ultimately affect the processing quality of the aluminum guide rollers. Utility Model Content

[0004] Therefore, it is necessary to provide a loading and unloading device for the processing of large aluminum guide rollers, which is needed to address the problem that aluminum guide rollers are prone to deflection during transport on the feeding conveyor, resulting in inaccurate workpiece positioning and processing errors.

[0005] The system includes: a cutting machine, a feeding conveyor, and a discharging conveyor; a positioning mechanism, which includes a first electric push rod located at the bottom of the feeding conveyor. A drive frame is fixedly connected to the telescopic end of the first electric push rod. Two positioning frames are slidably connected to the inner wall of the drive frame, and equally spaced rubber wheels are rotatably connected to the inner wall of each positioning frame. Through the cooperation of the first electric push rod and the drive frame, the spacing between the two sets of rubber wheels is adjusted, thereby limiting the movement of the large aluminum guide roller workpiece on the feeding conveyor. This ensures the accurate delivery of the large aluminum guide roller workpiece into the cutting machine, avoiding processing errors and guaranteeing the processing quality of the aluminum guide roller.

[0006] In one embodiment, a smooth block is fixedly connected to one side of the positioning frame, and the surface of the smooth block is a right-angled triangle. The smooth block provides initial guidance for the large aluminum guide roller workpiece entering the feeding conveyor, thereby preventing the workpiece from shifting during feeding and transportation, which could lead to collisions and scratches, protecting the surface quality of the workpiece, and ensuring that the two sets of rubber wheels accurately roll against the surface of the large aluminum guide roller workpiece, thus ensuring accurate feeding of the workpiece.

[0007] In one embodiment, a second electric push rod is fixedly connected to the top of the cutting machine, and a positioning frame is fixedly connected to the telescopic end of the second electric push rod.

[0008] In one embodiment, two placement seats are fixedly connected to the inner bottom wall of the cutting machine, and the bottom of the positioning frame and the surface of the placement seats are both curved into an arc shape. Through the cooperation of the second electric push rod, the positioning frame, and the placement seats, the aluminum guide roller is clamped and positioned, thereby ensuring the stability of the aluminum guide roller during processing and improving processing accuracy.

[0009] In one embodiment, a positioning sensor is fixedly connected to one side of the cutting machine.

[0010] In one embodiment, a fixed frame is fixedly connected to the bottom of the feeding conveyor. The surface of the first electric push rod is fixedly connected to the inner bottom wall of the fixed frame. The bottom of the drive frame is slidably connected to the inner bottom wall of the fixed frame, and the surface of the positioning frame is slidably connected to the inner wall of the fixed frame. The fixed frame protects the surface of the drive frame, preventing impurities from adhering to the surface of the drive frame and reducing wear between the drive frame and the positioning frame.

[0011] In one embodiment, the bottom of the positioning frame is rolled with equally spaced ball bearings, the surfaces of which are rolled to the top of the feeding conveyor. The ball bearings reduce friction between the positioning frame and the feeding conveyor.

[0012] In one embodiment, both the smooth block and the ball are stainless steel components.

[0013] Beneficial effects

[0014] 1. By cooperating with the first electric push rod and the drive frame, the spacing between the two sets of rubber wheels is adjusted, thereby limiting the movement of the large aluminum guide roller workpiece on the feeding conveyor. This ensures that the large aluminum guide roller workpiece is accurately delivered into the cutting machine, thus avoiding processing errors and ensuring the processing quality of the aluminum guide roller.

[0015] 2. The smooth block provides initial guidance for the large aluminum guide roller workpiece entering the feeding conveyor, thereby preventing the workpiece from shifting during feeding and transportation, which could lead to collisions and scratches, protecting the surface quality of the workpiece, and ensuring that the two sets of rubber wheels accurately roll on the surface of the large aluminum guide roller workpiece, thus ensuring accurate feeding of the workpiece.

[0028] The following is combined Figures 1-4 This invention describes a loading and unloading device for processing large aluminum guide rollers.

[0029] In one embodiment, a loading and unloading device for processing large aluminum guide rollers includes: a cutting machine 100, a loading conveyor 200, and an unloading conveyor 300; a positioning mechanism 400, the positioning mechanism 400 including a first electric push rod 403 provided at the bottom of the loading conveyor 200, a drive frame 404 fixedly connected to the telescopic end of the first electric push rod 403, two positioning frames 401 slidably connected to the inner wall of the drive frame 404, and rubber wheels 402 evenly distributed rotatably connected to the inner wall of the positioning frames 401.

[0030] The feeding conveyor 200 includes a feeding frame, a first conveying roller, a first conveyor belt, a first support roller, and a first servo motor. The surfaces of the first conveying roller and the first support roller are rotatably connected to the inner wall of the feeding frame. The surfaces of the two first conveying rollers are connected to the inner surface of the first conveyor belt. The surface of the first servo motor is fixedly connected to the front end of the feeding frame. The output shaft of the first servo motor is fixedly connected to one end of one of the first conveying rollers. The inner surface of the first conveyor belt contacts the surface of the first support roller.

[0031] The unloading conveyor 300 includes an unloading frame, a second conveying roller, a second conveyor belt, a second support roller, and a second servo motor. The surfaces of the second conveying roller and the second support roller are rotatably connected to the inner wall of the loading frame. The surfaces of the two second conveying rollers are connected to the inner surface of the second conveyor belt. The surface of the second servo motor is fixedly connected to the front end of the loading frame. The output shaft of the second servo motor is fixedly connected to one end of one of the second conveying rollers. The inner surface of the second conveyor belt contacts the surface of the second support roller.

[0032] The top of the drive frame 404 has two drive holes, which are octagonal in shape. The surface of the positioning frame 401 is slidably connected to the inner wall of the drive holes.

[0033] The cutting machine 100 typically consists of a cutting frame, a laser cutting mechanism, and a PLC touch screen. This is a relatively common and well-known technology in the field and is not closely related to the technical issues of this application. Therefore, it has not been described in detail.

[0034] The raw materials for large aluminum guide rollers are inspected to ensure that their material, dimensions, and surface quality meet processing requirements. The surface of the aluminum guide rollers is checked for defects such as cracks and pinholes. Dimensions such as diameter and length are measured to ensure they are within tolerance limits.

[0035] The laser cutting mechanism is debugged, including adjusting parameters such as the power, frequency, and pulse width of the laser generator to suit the material and processing requirements of the aluminum guide roller. Simultaneously, the position and focal length of the laser cutting head are calibrated to ensure the laser beam is accurately focused on the surface of the aluminum guide roller.

[0036] In this embodiment, when the large aluminum guide roller needs to be cut, the first electric push rod 403 is automatically activated by controlling the PLC touch screen on the cutting machine 100. The extension end of the first electric push rod 403 moves, driving the drive frame 404 to move. The movement of the drive frame 404 drives the positioning frame 401 to move, thereby bringing the two positioning frames 401 closer to each other and moving the two sets of rubber wheels 402 to the appropriate position. Special equipment such as a forklift is used to guide the large aluminum guide roller to the surface of the feeding conveyor 200, so that the rubber wheels 402 contact the surface of the large aluminum guide roller. By controlling the PLC touch screen on the cutting machine 100, the feeding conveyor 200 is automatically activated. The feeding conveyor 200 transports the surface of the large aluminum guide roller into the cutting machine 100. The rubber wheels 402 limit the movement of the large aluminum guide roller, so that the large aluminum guide roller is accurately moved into the cutting machine 100.

[0037] Based on the machining drawings of the aluminum guide roller, a laser cutting program is written using specialized programming software to determine parameters such as the cutting path, cutting speed, and cutting depth. At this point, the laser cutting head on the laser mechanism cuts the large aluminum guide roller according to the preset path.

[0038] like Figure 3-4As shown, a smooth block 405 is fixedly connected to one side of the positioning frame 401. The surface of the smooth block 405 is a right-angled triangle. A fixed frame 406 is fixedly connected to the bottom of the feeding conveyor 200. The surface of the first electric push rod 403 is fixedly connected to the inner bottom wall of the fixed frame 406. The bottom of the drive frame 404 is slidably connected to the inner bottom wall of the fixed frame 406. The surface of the positioning frame 401 is slidably connected to the inner wall of the fixed frame 406. The bottom of the positioning frame 401 is rolledly connected to equally arranged balls 407. The surface of the balls 407 is rolledly connected to the top of the feeding conveyor 200. Both the smooth block 405 and the balls 407 are stainless steel components.

[0039] In this embodiment, the smooth block 405 provides initial guidance to the large aluminum guide rollers that are guided onto the feeding conveyor 200, so that the large aluminum guide rollers can smoothly contact the rubber wheel 402.

[0040] like Figure 2 As shown, a second electric push rod 408 is fixedly connected to the top of the cutting machine 100, and a positioning frame 409 is fixedly connected to the telescopic end of the second electric push rod 408. Two placement seats 411 are fixedly connected to the inner bottom wall of the cutting machine 100. The bottom of the positioning frame 409 and the surface of the placement seat 411 are both curved into an arc shape. A positioning sensor 410 is fixedly connected to one side of the cutting machine 100.

[0041] In this embodiment, the feeding conveyor 200 transports the large aluminum guide roller, allowing it to slide precisely into the surfaces of the two placement seats 411. The positioning sensor 410 detects the position of the aluminum guide roller, at which point the second electric push rod 408 is automatically activated. The telescopic end of the second electric push rod 408 moves downward, causing the positioning frame 409 to move downward and abut against the surface of the aluminum guide roller, thereby positioning the aluminum guide roller. After processing, the second electric push rod 408 automatically opens, and the telescopic end of the second electric push rod 408 moves upward, causing the positioning frame 409 to move upward away from the surface of the aluminum guide roller. The PLC touch screen is then controlled to automatically activate the unloading conveyor 300, which transports the processed aluminum guide roller to a suitable position, allowing it to move out of the processing area and completing the unloading process. The entire loading and unloading process is automatically controlled by the control system, requiring only simple operations during loading and unloading, thus reducing labor intensity.

[0042] Working principle: The first electric push rod 403 is automatically activated. The telescopic end of the first electric push rod 403 moves through the drive frame 404, which drives the positioning frame 401 and the rubber wheel 402 to move to a suitable position. Special equipment such as a forklift is used to guide the large aluminum guide roller to the surface of the feeding conveyor 200. The smooth block 405 provides initial guidance for the large aluminum guide roller on the feeding conveyor 200, so that the large aluminum guide roller smoothly contacts the rubber wheel 402. The feeding conveyor 200 is automatically activated, and the surface of the large aluminum guide roller is precisely guided into the cutting machine 100.

[0043] It should be noted that the cutting machine 100, feeding conveyor 200, unloading conveyor 300, first electric push rod 403, second electric push rod 408, and positioning sensor 410 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the cutting machine 100, feeding conveyor 200, unloading conveyor 300, first electric push rod 403, second electric push rod 408, and positioning sensor 410 can be powered by the built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
