[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] The following describes in detail the overall structure, working principle, and technical effects of the auxiliary equipment for loading and unloading screen frames provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0036] Please refer to Figures 1 to 4 This utility model provides an auxiliary device for loading and unloading screen frames, including a positioning component 100, a lifting component 300, and a sensing component 500. The positioning component 100 is used to position and cooperate with the unloading bin 30, thereby ensuring the correct positioning of the auxiliary device and guaranteeing safety. The lifting component 300 is mounted on the positioning component 100 and is used to lift the screen frame 50, so that the screen frame 50 abuts against or separates from the unloading bin 30, reducing labor intensity and improving safety. The sensing component 500 is mounted on the lifting component 300 and is used to sense the pressure changes generated by the lifting component 300 during the lifting process, determining whether it has abutted against the screen frame 50 or the unloading bin 30, ensuring that the equipment operation is always within a controlled range. In other words, the three components cooperate to form a complete system, jointly ensuring the safety, accuracy, and efficiency of the loading and unloading process of the screen frame 50.

[0037] In practical applications, after the positioning component 100 and the feeding bin 30 are positioned and engaged, if the screen frame 50 is being disassembled, the lifting component 300 moves upward until it abuts against the screen frame 50 on the feeding bin 30. At this point, the sensing component 500 detects a pressure change, and the lifting component 300 stops rising. The operator can then release the latches between the feeding bin 30 and the screen frame 50. Subsequently, the lifting component 300 carrying the screen frame 50 moves downward, disengaging the screen frame 50 from the feeding bin 30, thus achieving disassembly. If the screen frame 50 is being installed, the lifting component 300 carrying the screen frame 50 moves upward until it abuts against the feeding bin 30. At this point, the sensing component 500 detects a pressure change, and the lifting component 300 stops rising. The operator can then engage the latches between the feeding bin 30 and the screen frame 50, securing the screen frame 50 to the feeding bin 30, thus achieving installation.

[0038] Please see Figure 2 and Figure 3 The positioning component 100 includes a positioning frame 110, which is connected to the lifting component 300 to provide a stable structural foundation for the entire device. This ensures that the lifting component 300 can operate stably and avoids operational errors caused by frame instability. Furthermore, the positioning frame 110 is equipped with a positioning part for positioning and engaging with the unloading hopper 30, ensuring that the screen frame 50 maintains the correct orientation and position during loading and unloading, preventing safety hazards caused by offset or misalignment.

[0039] In some embodiments, to improve operational efficiency, the positioning part is a guide chute 130. The guide chute 130 is used to partially position and cooperate with the discharge bin 30, so that the discharge bin 30 and the auxiliary equipment 10 are relatively fixed. It is easy to understand that, on the one hand, the limiting function of the guide chute 130 can prevent the screen frame 50 from moving excessively or falling off during loading and unloading, thus improving operational safety; on the other hand, through the guiding function of the guide chute 130, the docking process between the screen frame 50 and the discharge bin 30 is smoother, achieving accurate positioning in one go, reducing the time for manual adjustment, and significantly improving loading and unloading efficiency. In other embodiments, the positioning part can also be set as a positioning protrusion, and a guide chute 130 that cooperates with the positioning protrusion is correspondingly provided on the discharge bin 30.

[0040] To enhance the flexibility of the auxiliary equipment 10, the positioning assembly 100 also includes casters 150. The casters 150 are located at the bottom of the positioning frame 110, allowing operators to easily move the auxiliary equipment 10 to different working positions. This facilitates the rapid deployment of the auxiliary equipment 10 to the vicinity of different unloading bins 30, shortening preparation time and improving overall work efficiency. Furthermore, the casters 150 can be equipped with brakes to lock in place after the equipment has been moved, ensuring stability during operation and further enhancing safety.

[0041] As an optional embodiment, the lifting assembly 300 includes a cylinder 310 and a lifting rod 330. The cylinder 310 is connected to the positioning assembly 100, ensuring stable support of the lifting assembly 300 during operation. Furthermore, the cylinder 310 is driven by the lifting rod 330, which supports the screen frame 50. Therefore, the cylinder 310 can lift the screen frame 50 by driving the lifting rod 330 with compressed air, eliminating the need for manual intervention, reducing labor intensity, and improving safety. Optionally, multiple lifting rods 330 can be used to improve lifting stability and prevent swaying.

[0042] Furthermore, the lifting assembly 300 also includes a support frame 350, and the lifting rod 330 is used to support the screen frame 50 via the support frame 350. It should be noted that the support frame 350, as an intermediate structure, can evenly distribute the weight of the screen frame 50 onto the lifting rod 330, preventing damage to the cylinder 310 or the lifting rod 330 due to excessive localized stress. Further still, the sensing assembly 500 includes four pressure sensors 510, which are respectively located at the four corners of the support frame 350. Based on this, during the lifting process, the force exerted by the screen frame 50 on the lifting assembly 300 in four directions can be monitored simultaneously, ensuring that the screen frame 50 remains balanced throughout the loading and unloading process.

[0043] In addition, to further improve the efficiency, accuracy, and safety of the loading and unloading process of the screen frame 50, the auxiliary equipment 10 also includes a control component 700. The control component 700 is connected to the lifting component 300 and is used to control the lifting and lowering of the lifting component 300. In some embodiments, the control component 700 can be a manual control component 700, which controls the gas flow rate through a regulating valve to control the lifting speed of the lifting component 300; in other embodiments, the control component 700 can also be an automatic control component 700, which controls the gas flow rate by switching power on and off, so that the lifting component 300 is positioned at a specified height.

[0044] That is, in some embodiments, the control component 700 includes a pressure regulating valve 710 and an air pipe 730; wherein the output port of the pressure regulating valve 710 is connected to the air pipe 730, and the air pipe 730 is connected to the air inlet of the cylinder 310. It is easy to understand that by adjusting the opening of the pressure regulating valve 710, the flow rate of gas entering the cylinder 310 can be precisely controlled, thereby achieving flexible adjustment of the piston movement speed of the cylinder 310. This allows the lifting speed of the screen frame 50 to be optimized according to actual needs. In particular, different lifting speeds are required in different loading and unloading scenarios (such as rapid disassembly or slow docking), and the design of the pressure regulating valve 710 can meet these diverse needs.

[0045] In some embodiments, the control component 700 further includes a relay, and the lifting component 300 further includes a solenoid valve. The solenoid valve connects or disconnects the air source and cylinder 310, and the relay is communicatively connected to the sensing component 500 to enable or disable the solenoid valve. It is readily understood that the relay's communicative connection to the sensing component 500 allows for automatic control of the solenoid valve's on / off state based on feedback signals from the sensing component 500 (e.g., pressure sensor 510), thereby achieving automated operation. Specifically, when the sensing component 500 detects a pressure change, the relay immediately responds and controls the solenoid valve to stop operating, ensuring that the lifting component 300 stops at the correct position and preventing excessive rising or falling.

[0046] Taking the embodiments provided in this application as examples, the working principle and process of the auxiliary equipment for loading and unloading screen frames provided by this utility model are as follows:

[0047] When changing the screen, the operator moves the auxiliary equipment 10 below the feeding hopper 30 and secures it relative to the feeding hopper 30 via the guide slide 130, then locks the casters 150. Next, the lifting assembly 300 is activated, and the operator adjusts its lifting speed using the pneumatic regulating valve 710, causing the cylinder 310 to drive the lifting rod 330 to smoothly raise the support frame 350. Once the pressure sensor 510 detects that the support frame 350 is against the screen frame 50, the relay automatically cuts off, the solenoid valve stops operating, and the screen frame 50 stops at that position. Then, the operator opens the latch connecting the screen frame 50 to the feeding hopper 30, disengaging the screen frame 50 from the feeding hopper 30. Afterward, the pressure sensor 510 senses increased pressure, the relay closes, the solenoid valve opens and closes, and the lifting assembly 300 descends carrying the screen frame 50.

[0048] After the screen frame 50 returns to its auxiliary equipment position, the operator removes the screen from the screen frame 50 and installs a cleaned or new screen into it. Then, the lifting assembly 300 is activated, and the operator adjusts the lifting speed of the assembly 300 via the air pressure regulating valve 710, causing the cylinder 310 to drive the lifting rod 330 to smoothly return the screen frame 50 to its original position. Once the pressure sensor 510 detects that the screen frame 50 is against the material discharge bin 30, the relay automatically cuts off, the solenoid valve stops operating, and the screen frame 50 stops at that position. The operator then tightens the clips connecting the screen frame 50 and the material discharge bin 30, connecting them and completing the screen replacement. Afterward, the pressure sensor 510 senses a decrease in pressure, the relay closes, the solenoid valve opens and closes, compressed air is discharged through the vent 750, the lifting assembly 300 returns to its original position, the casters 150 unlock, and the auxiliary device moves out of its working position.

[0049] In summary, this utility model provides an auxiliary device for loading and unloading screen frames, including a positioning component 100, a lifting component 300, and a sensing component 500. The positioning component 100 is used to position and cooperate with the discharge bin 30, thereby ensuring the correct positioning of the auxiliary device and guaranteeing safety. The lifting component 300 is mounted on the positioning component 100 and is used to lift the screen frame 50 so that the screen frame 50 abuts against or separates from the discharge bin 30, thereby reducing labor intensity and improving safety. The sensing component 500 is mounted on the lifting component 300 and is used to sense the pressure changes generated by the lifting component 300 during the lifting process, thereby determining whether it has abutted against the screen frame 50 or the discharge bin 30, ensuring that the equipment operation is always within a controlled range. That is, the three components cooperate to form a complete system, jointly ensuring the safety, accuracy, and efficiency of the loading and unloading process of the screen frame 50.

[0050] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
