[0031] The working principle of the lifting mechanism of a slide conveyor proposed in the present invention is that when in use, the device is transported to a designated place, and the motor 4 is turned on. The motor 4 will drive the sliding mechanism to start working. At the same time, the lifting mechanism is connected through the connecting mechanism, so that while the sliding mechanism is working, the lifting mechanism can also operate normally, thereby changing the height of the lifting beam 3. During the lifting process of the device, the fixed beam 10 provides stable support for the device. When the device is operating normally, the material rack 5 is adjusted to a suitable height to ensure that the slide plate 6 can be lifted normally by the material rack 5, so that the device can complete the operation normally.

[0032] In one embodiment, for the above-mentioned lifting mechanism, the lifting mechanism includes a second bevel gear set 20 rotatably mounted on the device base 1, the second bevel gear set 20 is fixedly connected to one end of a connecting shaft 21, the other end of the connecting shaft 21 is fixedly connected to a third bevel gear set 22, the third bevel gear set 22 is fixedly connected to a one-way threaded rod 23, and the one-way threaded rod 23 is threadedly connected to a lifting assembly.

[0033] The working principle of the lifting mechanism of a slide conveyor proposed in the present invention is that the motor 4 in the turned-on state drives the second bevel gear set 20 to rotate, thereby driving the connecting shaft 21 to rotate, and then driving the third bevel gear set 22 to rotate inside the device base 1. The rotating third bevel gear set 22 drives the one-way threaded rod 23 to drive the lifting assembly to perform normal lifting operations through the action of the thread.

[0034] In one embodiment, for the above-mentioned lifting assembly, the lifting assembly includes a first lifting column 201, a threaded hole 24 is opened at the bottom of the first lifting column 201, a one-way threaded rod 23 is threadedly connected to the threaded hole 24, the first lifting column 201 is rotatably connected to the first gear 26, the first gear 26 is meshedly connected to the first rack 25, the first rack 25 is fixedly installed on the inner side of the fixed support column 2, and the first gear 26 is meshedly connected to the second rack 27.

[0035] In one embodiment, for the above-mentioned second rack 27, the second rack 27 is fixedly mounted on the second lifting column 202, the second lifting column 202 is rotatably connected to the second gear 28, the second gear 28 is meshedly connected to the third rack 29, the second gear 28 is meshedly connected to the fourth rack 30, and the fourth rack 30 is fixedly mounted on the third lifting column 203.

[0036] In one embodiment, for the above-mentioned lifting assembly, the lifting assembly is provided with two groups of fixed support columns 2, and the parts and installation methods thereof are the same.

[0037] The working principle of the lifting mechanism of the slide conveyor proposed by the present invention is that the one-way threaded rod 23 rotates in the threaded hole 24 and drives the first lifting column 201 to move upward or downward through the action of the thread, thereby driving the first gear 26 to move on the first rack 25. At the same time, the first gear 26 will move relative to the second rack 27 in the opposite direction of the first gear 26 on the first rack 25.

[0038] Furthermore, the lifting and lowering second rack 27 drives the second lifting column 202 to move synchronously, thereby driving the second gear 28 to move relative to the third rack 29, and then driving the second gear 28 to move on the fourth rack 30 in the opposite direction of the second gear 28 on the third rack 29, thereby realizing the position change of the third lifting column 203. The lifting function of the lifting mechanism enables the skid conveyor to be flexibly adjusted according to different production needs and site conditions. Whether it is transporting workpieces and skids from low to high, or from high to low, it can be easily achieved, thereby enhancing the adaptability and flexibility of the conveying system.

[0042] The working principle of the lifting mechanism of a slide conveyor proposed in the present invention is that when in use, turning on the motor 4 will drive the worm 12 set at the output end to rotate, the rotation of the worm 12 drives the worm wheel 14 to rotate, and the rotation of the bidirectional threaded rod 15 drives the slider 16 to move toward or away from each other in the second slide groove 17 through the action of the thread. When it is necessary to drive the material rack 5 to rise, the lifting mechanism drives the lifting beam 3 to move upward, and at the same time, the two sliders 16 move toward each other.

[0043] Furthermore, the movement of the two sliders 16 and the movement of the lifting mechanism will keep the belt 11 and the rotating wheel 18 always in a taut state, avoiding the loosening or breaking of the belt 11 when the device is operating. The change of the belt 11 drives the sliding beam 8 to slide on the first slide groove 9, so that the material rack 5 can change the height of the slide plate 6.

[0045] In one embodiment, for the telescopic rod 7 mentioned above, the telescopic rod 7 is rotatably connected to the lifting beam 3 , and the first bevel gear set 13 is fixedly connected to the worm 12 .

[0046] The working principle of the lifting mechanism of a slide conveyor proposed in the present invention is that the motor 4 in the turned-on state drives the first bevel gear set 13 to rotate, the rotation of the first bevel gear set 13 drives the telescopic rod 7 to rotate, and the rotation of the telescopic rod 7 drives the lifting mechanism to operate normally.
