It is suitable for the handling and transportation of various flat plates (such as metal plates, plastic plates, glass plates, etc.). Compared with belt conveyors, the roller conveyor mechanism has better adaptability when transporting flat plates, can better support the plane of the plates, and reduce the risk of deformation and damage of the plates.

[0003] According to the patent publication number CN220350778U, an adjustable roller conveyor is disclosed. The adjustable roller conveyor includes a guide plate, and the two ends of the guide plate are respectively provided with a reinforcement adjustment module and an auxiliary notch module that can be connected to another set of guide plates, and the reinforcement adjustment module includes a plug-in frame, and the bottom of the front end of the plug-in frame is provided with an end frame, and the bottom of the end frame is nested with a U-shaped positioning frame, and the top of the U-shaped positioning frame is connected to a hand pull ring through a reset rod, and a reset spring is provided on the outside of the hand pull ring, and a laser sensor is provided on the bottom side of the end frame.

[0004] The above scheme has the advantages of stable operation and high speed, but the above scheme still has certain limitations: since the above device lacks a stabilizing mechanism for materials, the materials are easily disturbed by various factors such as vibration, speed fluctuation or turning during the transportation process, resulting in displacement or sliding, which greatly reduces the accuracy and stability of material transportation; for this reason, we provide a negative pressure adsorption roller conveying mechanism to solve the above problems.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] The present embodiment provides a negative pressure adsorption roller conveying mechanism. By setting a first partition 6 and a negative pressure adsorption mechanism 7, when in use, the first partition 6 and the negative pressure adsorption mechanism 7 cooperate to limit the position of the material, thereby avoiding displacement or sliding of the material due to external factors during the conveying process, thereby greatly improving the accuracy and stability of material conveying.

[0023] Embodiment 1

[0024] like Figure 1-4As shown, a negative pressure adsorption roller conveying mechanism proposed by the utility model includes a bottom plate 1, the outer surface of the bottom plate 1 is fixedly connected to two symmetrical mounting plates 2, and the bottom surfaces of the two mounting plates 2 are fixedly connected to support legs 3.

[0025] The arrangement of the supporting legs 3 can keep a certain distance between the entire device and the ground, thereby reducing the probability of the device being corroded by ground moisture.

[0026] The upper surfaces of the two mounting plates 2 are fixedly connected with vertical plates 4 , and a group of rollers 5 arranged at equal distances are installed between the two vertical plates 4 .

[0027] The outer surface of the drum 5 is rotatably connected to the inner parts of the two vertical plates 4 .

[0028] A group of first partitions 6 arranged at equal distances are installed between the two vertical plates 4 .

[0029] Both ends of the first partition plate 6 are fixedly connected to the outer surface of the vertical plate 4 , and two groups of adsorption holes are opened on the surface of the first partition plate 6 .

[0030] Two symmetrical negative pressure adsorption mechanisms 7 are arranged above the bottom plate 1 . The negative pressure adsorption mechanism 7 includes a negative pressure chamber 701 . Two symmetrical protection mechanisms 8 are arranged inside the negative pressure chamber 701 .

[0031] Embodiment 2

[0032] like Figure 1-4 As shown, this embodiment further illustrates Example 1, the negative pressure adsorption mechanism 7 includes two symmetrical mounting frames 704, a group of equally spaced adsorption ports 702 are provided on the upper surface of the negative pressure bin 701, a second partition plate 703 is fixedly connected to the interior of the negative pressure bin 701, the bottom surface of the negative pressure bin 701 is fixedly connected to the upper surface of the base plate 1, and the upper surfaces of the two mounting frames 704 are fixedly connected to the bottom surface of the base plate 1.

[0033] There is a group of adsorption holes corresponding to the top of each adsorption port 702. The second partition plate 703 can separate the negative pressure chamber 701 into two parts, so that two air pumps 705 can be used for pumping air to avoid the negative pressure chamber 701 being too large and causing insufficient suction of the air pump 705.

[0034] The interior of the two mounting frames 704 are fixedly connected with air pumps 705, the upper surfaces of the two air pumps 705 are fixedly connected with exhaust pipes 706, the outer surfaces of the two exhaust pipes 706 are fixedly connected to the interior of the base plate 1, and the outer surfaces of the two exhaust pipes 706 are fixedly connected to the interior of the negative pressure chamber 701.

[0035] The bottom surfaces of the two air pumps 705 are fixedly connected to exhaust pipes 707 , and the outer surfaces of the two exhaust pipes 707 are fixedly connected to the inside of the mounting frame 704 .

[0036] During use, when the air pump 705 is started, its strong suction force will cause the air in the negative pressure bin 701 to flow rapidly through the exhaust pipe 706 and finally be discharged through the exhaust pipe 707, thereby forming a stable negative pressure environment inside the negative pressure bin 701. Under this negative pressure effect, the outside air is strongly attracted and continuously flows into the negative pressure bin 701 through the carefully designed adsorption holes and the special adsorption port 702 on the surface of the first partition 6. In this process, not only is the negative pressure state in the negative pressure bin 701 maintained, but more importantly, it also achieves the adsorption of materials, thereby avoiding displacement or sliding of materials due to external factors during the transportation process, thereby greatly improving the accuracy and stability of material transportation.

[0037] The protection mechanism 8 includes a slot 801, which is opened on the outer surface of the negative pressure chamber 701. A dustproof net 802 is inserted into the slot 801. A connecting plate 803 is fixedly connected to the outer surface of the dustproof net 802. An iron block 804 is fixedly connected to the inside of the connecting plate 803.

[0038] The dustproof net 802 can prevent external dust and impurities from entering the negative pressure chamber 701 through the suction port 702.

[0039] The outer surface of the negative pressure chamber 701 is fixedly connected to a fixed plate 806, the interior of the fixed plate 806 is slidably connected to a movable rod 807, the bottom surface of the movable rod 807 is fixedly connected to a handle 809, and the upper surface of the fixed plate 806 is fixedly connected to two symmetrical elastic members 808.

[0040] The connecting plate 803, the fixing plate 806, the movable rod 807, the elastic member 808 and the handle 809 are all made of metal materials that cannot be adsorbed by the magnet 805. The elastic member 808 is a spring, and the surface of the handle 809 is provided with a layer of hard rubber material that is non-slip and non-irritating.

[0041] The upper surface of the movable rod 807 is fixedly connected with a magnet 805 , and the top ends of the two elastic members 808 are fixedly connected with the bottom surface of the magnet 805 , so that the iron block 804 and the magnet 805 are attracted to each other.

[0042] When in use, pull the handle 809 downward to drive the movable rod 807 to move inside the exhaust pipe 706, driving the magnet 805 to move. As the magnet 805 moves, the elastic member 808 will be compressed, causing the elastic member 808 to generate elastic force. Then, insert the dustproof net 802 into the interior of the slot 801 by holding the connecting plate 803. Finally, release the handle 809. Under the elastic force of the elastic member 808, the magnet 805 is quickly reset and adsorbed on the iron block 804. At this time, the firmly installed dustproof net 802 can prevent external dust and impurities from entering the negative pressure chamber 701 through the adsorption port 702, and this installation method can facilitate the cleaning or replacement of the dustproof net 802 at a later time.

[0043] Working principle: During use, when the air pump 705 is started, its strong suction force will cause the air in the negative pressure bin 701 to flow rapidly through the exhaust pipe 706 and finally be discharged through the exhaust pipe 707, thereby forming a stable negative pressure environment inside the negative pressure bin 701. Under this negative pressure effect, the outside air is strongly attracted and continuously flows into the negative pressure bin 701 through the carefully designed adsorption holes on the surface of the first partition 6 and the special adsorption port 702. In this process, not only is it ensured that the negative pressure state in the negative pressure bin 701 is maintained, but more importantly, it also realizes the adsorption of materials, thereby avoiding displacement or sliding of materials due to external factors during the transportation process, greatly improving the accuracy and stability of material transportation. The magnet 805 is driven to move. As the magnet 805 moves, the elastic part 808 is compressed, causing the elastic part 808 to generate elastic force. Then, the dustproof net 802 is inserted into the interior of the slot 801 by holding the connecting plate 803. Finally, the handle 809 is released. Under the elastic force of the elastic part 808, the magnet 805 is quickly reset and adsorbed on the iron block 804. At this time, the firmly installed dustproof net 802 can prevent external dust and impurities from entering the negative pressure chamber 701 through the adsorption port 702, and this installation method can facilitate the cleaning or replacement of the dustproof net 802 at a later time.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
