[0038] See also Figures 1 to 4 ,like Figure 1 As shown, a load-bearing test device for a clothes drying machine includes a frame 1, a positioning unit, a sliding assembly, a control unit and a lifting platform.

[0039] Clothes drying machine, such as Figure 1 and Figure 2 As shown, it includes a housing 21, a rope retractor, a rope 23, and a steering wheel 24; the rope retractor is fixed to the housing 21 and is used to retract and release the rope 23. The two ends of the rope 23 extend from both sides of the rope retractor and are suitable for passing around the corresponding steering wheel 24. Each rope 23 is provided with a connecting portion. The rope retractor includes a rope retractor wheel 22, a motor, and a motor controller. The motor controller controls the forward and reverse rotation of the motor to drive the rope retractor wheel 22. Specifically, the rope 23 is a steel wire rope, and the connecting portion is steel wire rope aluminum pellets. The clothes drying machine is placed on a support member 11, which is a horizontally placed flat plate. The support member 11 is provided with a test position mark to facilitate manual alignment by the operator.

[0040] Rack 1, such as Figure 1 and Figure 2 As shown, the frame 1 is welded with high-strength steel to ensure the stability and load-bearing capacity of the overall structure. A conveyor belt 9 is provided on the frame 1. The conveyor belt 9 extends horizontally and is connected to the upper and lower production processes of the clothes drying machine. The conveyor belt 9 moves the supporting member 11 horizontally to enter or leave the test position of the frame 1. The frame 1 is also provided with at least one clamping member 8, and the clamping member 8 is provided with a number of placement slots of different shapes. The introduction of the conveyor belt 9 realizes the seamless connection of the clothes drying machine on the test production line. This design not only simplifies the test process, but also improves the test efficiency, allowing the clothes drying machine to quickly enter or leave the test position, thereby meeting the needs of large-scale production testing.

[0041] Positioning unit, such as Figure 1 、 Figure 2 and Figure 4As shown, it includes a positioning member 2 and a positioning member driver. The positioning unit is suitable for sliding in the up and down direction relative to the frame 1 so that the clothes drying machine placed on the supporting member 11 is fixed relative to the frame 1. Specifically, the positioning member 2 slides up and down along the slide rail protruding from the frame 1 to fix the housing 21 of the clothes drying machine. The positioning member driver is a servo motor, which drives the positioning member 2 to lift and fix the clothes drying machine. There are two positioning units, which are respectively arranged on both sides of the clothes drying machine housing 21. In this embodiment, the structure of the positioning unit includes a positioning member 2 and a positioning member driver. This allows the clothes drying machine to be stably fixed during the test, avoiding movement or shaking during the test, thereby improving the accuracy and reliability of the test.

[0042] The sliding assembly is adapted to slide up and down relative to the frame 1. The sliding assembly comprises a carriage 3, a carriage 3 driver, and a mating portion 12. The carriage 3 is located above the support plate and is controlled by the carriage 3 driver to slide up and down relative to the frame 1. The mating portion 12 is fixed to the carriage 3 and corresponds to the clothes drying machine steering wheel 24. The mating portion 12 is adapted to connect to the connecting portion of the rope 23 that passes around the corresponding steering wheel 24, so that the sliding assembly can pull the rope 23. Specifically, as Figure 4 As shown, the mating portion 12 is designed as a notch to facilitate the smooth insertion and securement of the steel wire rope and aluminum pellets. This ensures a secure connection and prevents them from falling off during testing or use. The slide assembly's carriage 3, driven by the master controller, synchronizes its movement with the clothes drying machine's cord retractor to simulate the forces experienced during actual use. There are two slide assemblies, one on each side of the clothes drying machine housing 21. In this embodiment, the carriage 3 is driven by a servo motor.

[0043] In this embodiment, by symmetrically placing positioning units and sliding assemblies on both sides of the housing 21, a balanced force test is achieved on both sides of the clothes dryer. This design is more closely aligned with the actual use of the clothes dryer, enabling a comprehensive assessment of the clothes dryer's performance under complex force conditions, providing users with more reliable test results.

[0044] Control unit, such as Figures 1 to 3As shown, it includes a main controller, a remote control 5, a signal receiver 6, a manipulator 7, a human-computer interaction unit 10 and a test button 13. The main controller is used to control the rope retractor to retract and release the rope 23, and when releasing the rope 23, control the sliding assembly to slide relative to the housing 21 in a direction away from the clothes drying machine to test the pulling force, and when reeling the rope 23, control the sliding assembly to test the pulling force and pull the rope 23 to resist the reeling force of the rope retractor. Specifically, the main controller adopts a programmable logic controller (PLC), which is responsible for receiving the test parameters input by the user and controlling the movement of the positioning unit, the sliding assembly and the rope retractor. Specifically, the main controller controls the positioning member driver, the slide 3 driver and the motor controller to drive the corresponding positioning member 2, the slide 3 and the motor to work. The main controller also has data acquisition and processing functions, and can record various parameters during the test in real time.

[0045] The remote control 5 is a signal transmitter, which is connected to the signal receiver 6. Different types of clothes drying machines have remote controls 5 of different shapes and sizes, such as rectangular and square remote controls 5. The remote control 5 is fixed to the frame 1. Specifically, the clamping member 8 on the frame 1 fixes the remote control 5. The clamping member 8 is provided with a number of placement slots of different shapes to accommodate remote controls 5 of different shapes and sizes. By adding the clamping member 8 to fix the remote control 5, the stability of the remote control 5 during the test is ensured, so that the manipulator 7 can simulate human hands to operate the remote control 5 to send signals, simplifying the preparation work before the test and improving the test efficiency. The flexible design of the placement slot enables it to be compatible with and firmly place remote controls 5 of various shapes and sizes, thereby improving the versatility and flexibility of the test device.

[0046] The signal receiver 6 is fixed to the frame 1 and is close to the remote control 5. The signal receiver 6 is electrically connected to the motor controller of the clothes drying machine. Specifically, the operator needs to manually connect the wires of the motor controller to the signal receiver 6 before testing, and disconnect the wires from the signal receiver 6 after the test is completed.

[0047] Manipulator 7 is located above remote control 5 and is controlled by the main controller to simulate a human hand operating remote control 5 to send signals. Specifically, the main controller controls manipulator 7 to move horizontally or vertically relative to frame 1 to press the buttons on remote control 5. Specifically, the main controller controls the servo motor of manipulator 7 to control the movement of manipulator 7. When the main controller controls manipulator 7 to press the down button on remote control 5, it simultaneously controls the driver of carriage 3 to drive carriage 3 upward; when the up button is pressed, it controls the driver of carriage 3 to pull rope 23 to test the pulling force. The main controller controls the forward, backward, and upward movement trajectory of manipulator 7 pressing remote control 5 and records the position coordinates. After the setting is completed, manipulator 7 can automatically move according to the set movement trajectory to press remote control 5.

[0048] In this embodiment, remote control of the clothes drying machine is achieved through the cooperation of remote control 5 and signal receiver 6. A manipulator 7 simulates the human hand operating remote control 5 to send signals. Under the control of the master controller, manipulator 7 can simulate the various actions of a user operating remote control 5, thus realistically recreating the actual scene of a user controlling the clothes drying machine. The master controller controls the rope retractor according to the instructions of signal receiver 6, making the test more similar to actual use.

[0049] In this embodiment, the main controller controls the action of the slide 3 driver so that the sliding assembly can apply a constant force during the rising and falling process according to the test requirements to simulate the performance of the clothes drying machine under different load-bearing conditions.

[0050] The human-machine interaction unit 10 is fixed to the frame 1 and is electrically connected to the main controller so that the main controller is suitable for being controlled. The human-machine interaction unit 10 is suitable for allowing the user to set the load-bearing test force value parameters, or call the stored test parameters of the same type of clothes drying machine, as well as the operating trajectory of the sliding component, positioning unit and manipulator 7. The intuitive design of the human-machine interaction unit 10 provides employees with a convenient operation interface. Employees can easily set test parameters, call stored test templates and monitor the test process through the unit, which improves the flexibility and convenience of the test, reduces the difficulty of operation and the error rate, and makes the test work more efficient and accurate.

[0051] Test button 13, such as Figure 1 and Figure 2 As shown, it is located to the operator's right and contains start, pause, and emergency stop buttons. To begin a test, the operator presses the start button, and the master controller initiates control. After the test is complete, the operator presses the start button again, and conveyor belt 9 transports support member 11 and the clothes drying machine off rack 1 for the next process.

[0052] A lifting platform (not shown in the figure) is provided below the test position and is adapted to push the supporting member 11 upward in the vertical direction to prevent it from moving downward relative to the frame 1. The lifting platform descends in the vertical direction, and the supporting member 11 returns to the conveyor belt 9 so as to be transported away. Specifically, when the supporting member 11 enters the test position and begins testing, the lifting platform rises to push against the supporting member 11, causing it to leave the conveyor belt 9; after the test is completed, the lifting platform descends, and the supporting member 11 returns to the conveyor belt 9 and is transported away. The lifting platform is controlled by a drive mechanism, specifically, a cylinder. In this embodiment, the lifting platform ensures stable support of the clothes drying machine during the test. At the beginning of the test, the lifting platform rises rapidly to push against the supporting member 11, causing it to detach from the conveyor belt 9 and remain fixed; after the test is completed, the lifting platform descends smoothly, allowing the supporting member 11 to return to the conveyor belt 9 and be transported away. This design not only improves the continuity and efficiency of the test, but also ensures the safety of the test process.

[0053] In this embodiment, the testing device comprehensively tests the overall load-bearing capacity of a clothes airer by simulating the actual rope retraction and extension process of the clothes airer. This includes testing the clothes airer's ability to withstand external pulling forces when the rope 23 is released, and its ability to resist the retraction force of the rope retractor when the rope 23 is reeled in. The positioning unit can slide vertically, ensuring that the clothes airer remains stably fixed relative to the frame during testing, avoiding testing errors caused by positional offset. The mating portion 12 on the sliding assembly mates with the clothes airer's steering wheel 24 and the connection between the rope 23, ensuring that the testing process is consistent with the clothes airer's actual operating conditions and simulating the rope 23 retraction and extension state during normal use. Simultaneously, the sliding assembly can be operated to apply the required test force to the rope 23 to verify the clothes airer's compliance. Using this testing device to perform load-bearing tests on clothes airers automates the testing process and improves testing efficiency.

[0054] Clothes drying machine load-bearing test device operation process:

[0055] 1. Preparation for the first sample test

[0056] Transport by conveyor belt 9 : First, the clothes drying machine placed on the supporting member 11 is transported to a predetermined test position in the rack 1 by the conveyor belt 9 .

[0057] Clothes drying machine positioning: When the clothes drying machine reaches the test position, the operator needs to manually align the housing 21 of the clothes drying machine with the test position mark on the support member 11. This step is completed through visual judgment and fine-tuning to ensure the stability of the clothes drying machine during the test.

[0058] Setting test parameters: Based on the type of clothes drying machine being tested, the operator sets the corresponding load-bearing test force value in the human-computer interaction unit 10. This step ensures that the test conditions meet the actual usage scenario of the clothes drying machine.

[0059] 2. Test Preparation and Connection

[0060] Signal component preparation: Place the remote control 5 in the placement slot of the adapted clamping member 8 in the signal component to ensure that the remote control 5 can remain stable during the test.

[0061] Rope 23 connection: Rope 23 is passed around the corresponding steering wheel 24 on the clothes drying machine, and the steel wire rope aluminum pellet is connected to the matching part 12 of the sliding assembly. This connection step needs to ensure that the rope 23 will not loosen or shift during the test.

[0062] Electrical connection: The operator manually connects the control circuit of the clothes drying machine to the signal receiver 6 to ensure that the signal can be accurately transmitted to the clothes drying machine control system.

[0063] 3. Test Execution

[0064] To secure the clothes drying machine: The operator presses the test button 13, and the lifting platform pushes upward against the support 11. The positioning unit then firmly presses the housing 21 of the clothes drying machine onto the support 11. After positioning is complete, the system automatically stores the coordinates of the positioning unit's movement for subsequent testing.

[0065] Test Operation: The main controller instructs the robot 7 to press the "up" or "down" button on the remote control 5, simulating a user operating a clothes drying machine. As the remote control 5 is operated, the rope 23 moves the clothes drying machine up or down, and the sliding assembly applies a preset test force.

[0066] Performance test: During the test, observe whether the clothes dryer alarms or displays any other abnormalities. If the clothes dryer can withstand the test force without alarming, it is considered qualified.

[0067] Limit setting: After the test is qualified, the button on the remote control 5 is pressed again by the manipulator 7 to control the clothes drying machine to rise to the upper limit of the rope 23. Subsequently, the rope 23 is lowered by a preset distance to facilitate the installation of subsequent processes.

[0068] 4. Test completion and subsequent processing

[0069] Disassembly and tidying up: After the test is completed, remove the aluminum pellets of the wire rope from the mating part 12 of the sliding assembly and tidy up the test site.

[0070] Clothes drying machine circulation: the operator presses the test button 13, the jacking platform descends, the supporting member 11 returns to the conveyor belt 9, the positioning member 2 slides upward and away from the clothes drying machine, and the clothes drying machine flows into the next process through the conveyor belt 9 for subsequent processing.

[0071] 5. Automation and parameter storage

[0072] Parameter Storage: After completing the initial sample setup, the system stores the trajectory coordinates of the positioning unit, sliding assembly, and manipulator 7 in the human-machine interface unit 10. This allows subsequent testing to be performed manually, requiring only the manual hooking of the steel wire rope aluminum pellets into the sliding assembly's mating portion 12 and the manual connection of the clothes drying machine's control circuit to the signal receiver 6. The remaining steps are automatically executed according to the pre-set parameters, improving testing efficiency. The system can store different test parameters for different clothes drying machine models. By calling the corresponding parameter group, rapid adaptation and testing of different models can be achieved.

[0073] Through the above-mentioned operating procedures, the clothes drying machine load-bearing testing device can realize comprehensive, accurate and efficient testing of the clothes drying machine's load-bearing performance, providing strong guarantee for the quality control of the clothes drying machine.
