Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to an intermittent negative pressure adsorption belt conveyor mechanism. Background Art

[0002] Belt conveyor mechanism is a material conveying equipment commonly used in factory automated production lines. Its main function is to transport materials such as plates from one place to another. It is usually used for continuous operations on production lines. Belt conveyors have the advantages of simple structure, stable operation, high conveying efficiency, and easy automation control.

[0003] At present, many belt conveyors on the market often lack a special conveyor belt cleaning mechanism in their design. This lack will lead to a gradual increase in the accumulation of materials and impurities on the conveyor belt, which in turn causes considerable wear and corrosion to the conveyor belt. In the long run, this continuous damage will significantly shorten the service life of the conveyor belt and increase the cost and frequency of equipment maintenance. For this reason, we provide an intermittent negative pressure adsorption belt conveyor mechanism to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The present embodiment provides an intermittent negative pressure adsorption belt conveyor mechanism. By setting a conveyor belt 5 and a cleaning mechanism 7, when in use, the cleaning mechanism 7 can be used to clean the materials and impurities accumulated on the surface of the conveyor belt 5, thereby preventing these materials and impurities from causing significant wear and corrosion to the conveyor belt 5, effectively extending the service life of the conveyor belt 5 and reducing the cost and frequency of equipment maintenance.

[0022] Embodiment 1

[0023] like Figure 1-4 As shown, the utility model proposes an intermittent negative pressure adsorption belt conveyor mechanism, which includes a bottom plate 1, a group of supporting legs 2 are fixedly connected to the bottom surface of the bottom plate 1, and a base 3 is fixedly connected to the bottom surface of each supporting leg 2.

[0024] The setting of the supporting leg 2 not only supports the entire device, but also separates the entire device from the ground at a certain distance to prevent ground moisture from invading the device and causing corrosion to certain components. Fixing holes are provided on the surface of the base 3. By inserting expansion screws into the fixing holes, the entire device can be fixed to improve the stability of the device.

[0025] Two symmetrical brackets 4 are fixedly connected to the upper surface of the base plate 1 .

[0026] The main function of the bracket 4 is to install the conveying roller and the cleaning mechanism 7.

[0027] A conveyor belt 5 is provided above the bottom plate 1 , a negative pressure adsorption mechanism 6 is provided above the bottom plate 1 , and a cleaning mechanism 7 is provided above the bottom plate 1 .

[0028] Embodiment 2

[0029] like Figure 1-4As shown, this embodiment further illustrates Example 1, the negative pressure adsorption mechanism 6 includes an adsorption groove 602, the outer surface of the conveyor belt 5 is provided with an adsorption hole 601, the bottom surface of the adsorption groove 602 is fixedly connected to the upper surface of the bottom plate 1, and the interior of the adsorption groove 602 is fixedly connected with two symmetrical partition plates 603.

[0030] The upper surface of the adsorption groove 602 should be in contact with the bottom surface of the conveyor belt 5, and the partition plate 603 divides the adsorption groove 602 into multiple areas.

[0031] A group of air pumps 604 are fixedly connected to the bottom surface of the bottom plate 1 , and an upper surface of each air pump 604 is fixedly connected to an air extraction pipe 605 , and an outer surface of each air extraction pipe 605 is fixedly connected to the inside of the bottom plate 1 .

[0032] To achieve intermittent adsorption, each air pump 604 is driven and controlled individually.

[0033] The top end of each exhaust pipe 605 is fixedly connected to the bottom surface of the adsorption tank 602 , and the bottom surface of each air pump 604 is fixedly connected to an exhaust pipe 606 .

[0034] When the air pump 604 is started, a strong suction force is generated, so that the air in the adsorption tank 602 is extracted through the exhaust pipe 605 and discharged from the exhaust pipe 606, thereby forming a negative pressure environment in the adsorption tank 602. Under the action of negative pressure, the external air enters the adsorption tank 602 through the adsorption hole 601 on the conveyor belt 5, and adsorbs the material at the same time. The material is firmly adsorbed on the conveyor belt 5 under the action of negative pressure, thereby achieving stable transportation of the material. At the same time, the partition plate 603 divides the adsorption tank 602 into multiple areas, each area corresponds to a separately driven air pump 604. When it is necessary to take material from a certain area, it is only necessary to turn off the air pump 604 corresponding to the area, thereby achieving the purpose of intermittent adsorption.

[0035] The cleaning mechanism 7 includes a mounting column 701 and a mounting plate 708 . The bottom surface of the mounting column 701 is fixedly connected to the upper surface of one of the brackets 4 . The interior of the mounting column 701 is rotatably connected to a rotating shaft 702 . The upper surface of the mounting column 701 is provided with a first threaded hole 703 .

[0036] A second threaded hole 704 is formed on the upper surface of the mounting column 701 , a rotating plate 705 is fixedly connected to the outer surface of the rotating shaft 702 , the inner thread of the rotating plate 705 is connected to a limiting screw 706 , and the outer surface of the limiting screw 706 is connected to the inner thread of the second threaded hole 704 .

[0037] like Figure 3As shown, the rotating plate 705 rotates counterclockwise by ninety degrees, so that the limiting screw 706 is located directly above the first threaded hole 703. A rotating handle is fixed to the top of the limiting screw 706, and a layer of anti-slip and anti-grinding hard rubber material is provided on the surface of the rotating handle.

[0038] Two symmetrical connecting rods 707 are fixedly connected to the upper surface of the mounting plate 708 . The upper surfaces of the two connecting rods 707 are fixedly connected to the bottom surface of the rotating plate 705 . A brush 709 is fixedly connected to the bottom surface of the mounting plate 708 .

[0039] The mounting plate 708 and the brush 709 are fixed by screws, and this fixing method makes it easy for the staff to clean or replace the brush 709.

[0040] When in use, the limiting screw 706 is rotated until the limiting screw 706 is completely disengaged from the inside of the second threaded hole 704, and the limit on the rotating plate 705 can be released. Then, the rotating plate 705 is rotated to drive the rotating shaft 702 to rotate inside the mounting column 701, drive the connecting rod 707 to rotate, drive the mounting plate 708 to rotate, and drive the brush 709 to rotate until the limiting screw 706 is located directly above the first threaded hole 703. Then, the limiting screw 706 is screwed into the inside of the first threaded hole 703 to limit the rotating plate 705 after rotation. At this time, the belt conveyor is started. When the conveyor belt 5 passes under the brush 709, the materials and impurities accumulated on its surface will be cleaned. When the cleaning is completed, the brush 709 can be reset. This method can prevent these materials and impurities from causing considerable wear and corrosion to the conveyor belt 5, effectively extending the service life of the conveyor belt 5, and reducing the cost and frequency of equipment maintenance. At the same time, cleaning the conveyor belt 5 can also prevent those aggregates from clogging the adsorption hole 601.

[0041] Working principle: When in use, rotate the limiting screw 706 until the limiting screw 706 is completely out of the second threaded hole 704, and the limiting of the rotating plate 705 can be released. Then rotate the rotating plate 705, drive the rotating shaft 702 to rotate inside the mounting column 701, drive the connecting rod 707 to rotate, drive the mounting plate 708 to rotate, and drive the brush 709 to rotate until the limiting screw 706 is located directly above the first threaded hole 703, and then screw the limiting screw 706 into the first threaded hole 703. The rotating plate 705 is limited after rotation, and the belt conveyor is started at this time. When the conveyor belt 5 passes under the brush 709, the materials and impurities accumulated on its surface will be cleaned, and when the cleaning is completed, the brush 709 can be reset. This method can prevent these materials and impurities from causing considerable wear and corrosion to the conveyor belt 5, effectively extending the service life of the conveyor belt 5, and reducing the cost and frequency of equipment maintenance. At the same time, cleaning the conveyor belt 5 can also prevent those aggregates from clogging the adsorption holes 601. When the air pump 604 is started, a strong suction force is generated, so that the air in the adsorption tank 602 is extracted through the exhaust pipe 605 and discharged from the exhaust pipe 606, thereby forming a negative pressure environment in the adsorption tank 602. Under the action of negative pressure, the external air enters the adsorption tank 602 through the adsorption hole 601 on the conveyor belt 5, and adsorbs the material at the same time. The material is firmly adsorbed on the conveyor belt 5 under the action of negative pressure, thereby achieving stable transportation of the material. At the same time, the partition plate 603 divides the adsorption tank 602 into multiple areas, each area corresponds to a separately driven air pump 604. When it is necessary to take material from a certain area, it is only necessary to turn off the air pump 604 corresponding to the area, thereby achieving the purpose of intermittent adsorption.
