AI Technical Summary
Automatic unloading machines are prone to tipping over during board handling due to a shift in the center of gravity. They lack anti-tipping devices to accommodate adjustments in the unloading plate angle, which affects production efficiency and poses safety hazards.
An anti-tipping device was designed, including a feeding plate, a side groove limiting frame, a support frame, a support block, a support rod, and a servo motor. The servo motor controls the bidirectional threaded rod and the limiting rod to drive the support block to move, thereby achieving double-sided support for the feeding plate and adapting to angle adjustment.
Regardless of how the angle of the feed plate is adjusted, it can provide stable support and prevent tipping, thus improving the flexibility and safety of the equipment.

Technical Field
[0001] This utility model relates to the field of safety protection equipment technology, and more specifically, to an anti-tipping device for an automatic unloading machine. Background Technology
[0002] Artificial quartz stone slabs are made from high-purity quartz sand powder and resin, among other auxiliary materials, through high-pressure pressing using advanced technology. Automatic unloading machines are automated equipment used for processing and handling artificial quartz stone slabs. They are primarily used to automatically transfer artificial quartz stone slabs from the production line or stacking area to designated locations, and are widely used in furniture manufacturing, building materials, and the electronics industry. Their core function is to achieve rapid and precise handling and stacking of artificial quartz stone slabs, thereby improving production efficiency and reducing manual operation.
[0003] During the handling of sheet metal, automatic unloading machines are prone to tilting due to uneven weight distribution, equipment vibration, and external environmental interference. This not only affects production efficiency but may also cause safety accidents. However, in actual use, the angle of the unloading plate often needs to be adjusted, and there is a lack of an anti-tipping device that can be adapted to the angle adjustment of the unloading plate to ensure the stability of the automatic unloading machine.

[0025] Example:
[0026] Please see Figures 1-3 An anti-tipping device for an automatic unloading machine, comprising:
[0027] The material feed plate 1 has side groove limiting frames 2 fixedly connected to both outer surfaces of its two sides; and
[0028] The support frame 3 has two support blocks 8 slidably connected inside. The top of each support block 8 is rotatably connected to a support rod 6. One end of each support rod 6 is rotatably connected to a composite rotating rod block 7. The two composite rotating rod blocks 7 are slidably connected to the two side groove limiting frames 2 respectively. A control box 4 is fixedly connected to one outer surface of the support frame 3. A bidirectional threaded rod 10 is rotatably connected between the two inner walls of the control box 4. Two connecting blocks 11 are threadedly connected to the bidirectional threaded rod 10. The two connecting blocks 11 are fixedly connected to the two support blocks 8 respectively.
[0029] In a specific embodiment of this utility model, the feeding plate 1 is the main feeding component of the feeding machine. When the feeding plate 1 is adjusted in actual use, the limiting rod 12 is controlled to rotate, which drives the two connecting blocks 11 to move closer or further apart, and drives the two support blocks 8 to move closer or further apart. Through the two support rods 6, the two composite rotating rod blocks 7 move inside the two side groove limiting frames 2, so that after the angle of the feeding plate 1 is adjusted, the support frame 3, the two support rods 6, the two composite rotating rod blocks 7 and the two support blocks 8 support the feeding plate 1 on both sides. No matter how the angle of the feeding plate 1 is adjusted, it can stably support the feeding plate 1 on both sides, preventing the feeding plate 1 from tipping over. It is highly flexible and very practical.
[0030] Specifically, a servo motor 5 is fixedly installed on one outer surface of the control box 4, and the output end of the servo motor 5 is fixedly connected to the bidirectional threaded rod 10.
[0031] In this embodiment, the rotation of the bidirectional threaded rod 10 can be controlled by starting the servo motor 5.
[0032] Specifically, a limit rod 12 is fixedly connected between the inner walls of both sides of the control box 4, and both connecting blocks 11 are slidably sleeved on the limit rod 12.
[0033] In this embodiment, the limiting rod 12 enables the two connecting blocks 11 to remain stable during relative movement.
[0034] Specifically, the limit rod 12 is made of stainless steel.
[0035] In this embodiment, the surface of the limiting rod 12 is smooth, and the friction between it and the two connecting blocks 11 is small.
[0036] Specifically, two stabilizing rods 9 are fixedly connected between the inner walls of both sides of the support frame 3, and the two support blocks 8 are slidably sleeved on the two stabilizing rods 9.
[0037] In this embodiment, two stabilizing rods 9 are used to support two support blocks 8, while enabling the two support blocks 8 to maintain stable movement.
[0038] Specifically, both stabilizer bars 9 are made of stainless steel.
[0039] In this embodiment, the surfaces of the two stabilizer bars 9 are smooth, rust-resistant, and suitable for long-term exposure.
[0040] Working principle: When the cutting plate 1 is adjusted in actual use, the limiting rod 12 is controlled by the servo motor 5 to rotate, causing the two connecting blocks 11 to move closer or further apart, and causing the two support blocks 8 to move closer or further apart. Through the two support rods 6, the two composite rotating rod blocks 7 move inside the two side groove limiting frames 2, so that after the angle of the cutting plate 1 is adjusted, the support frame 3, the two support rods 6, the two composite rotating rod blocks 7 and the two support blocks 8 support the cutting plate 1 on both sides. No matter how the angle of the cutting plate 1 is adjusted, it can stably support the cutting plate 1 on both sides, preventing the cutting plate 1 from tipping over. It is highly flexible and very practical. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power component and the power supply are common knowledge in this field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
