Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a material conveying mechanism. Background Art

[0002] Material conveying mechanism is an indispensable part of industrial production and logistics system. Its main function is to realize the handling, lifting, lowering, horizontal transportation and distribution of materials. There are many types of material conveying mechanisms, which are used in different material conveying fields. Among them, belt conveyors are extremely widely used. They are suitable for continuous transportation of bulk materials or piece items. They are composed of belts, rollers, rollers, drive devices, etc., and have the advantages of large conveying capacity, long transportation distance, simple structure and easy maintenance.

[0003] However, when the existing belt material conveying mechanism is working, if the material falls from a height onto the conveyor belt, due to the large weight of some materials, the material falling on the conveyor belt will cause a momentary large impact on the conveyor belt, resulting in a sudden increase in the tension of the conveyor belt. Over time, it is easy to cause the conveyor belt to break and be damaged, greatly reducing the service life of the conveyor belt. In addition, after some materials are conveyed, some impurities may adhere to the surface of the conveyor belt, which requires manual cleaning. Otherwise, it may affect the normal operation of the conveyor belt. Manual cleaning is time-consuming and labor-intensive, and has low efficiency. Utility Model Content

[0025] It is understandable that the other end of the conveyor belt 4 is externally connected to a driven roller and a mounting support mechanism, which is an existing technical application and is well known to those skilled in the art, so it is not described in detail here.

[0026] The buffering and shock-absorbing structure 7 includes a base 701, a damping telescopic rod 702, a spring sheet 703, a mounting seat 704 and a supporting roller 705. There are multiple damping telescopic rods 702 and supporting rollers 705. Multiple damping telescopic rods 702 are fixedly mounted on the top of the base 701. There are two groups of spring sheets 703. The two groups of spring sheets 703 are fixedly mounted on the top of the base 701, and the two groups of spring sheets 703 are respectively close to the two sides of the base 701. The mounting seat 704 is a U-shaped seat. The bottom of the mounting seat 704 is fixedly connected to the tops of the multiple damping telescopic rods 702 and the two groups of spring sheets 703. Multiple supporting rollers 705 are rotatably mounted inside the mounting seat 704, and the top height of the supporting roller 705 is higher than the top of the mounting seat 704. The height of the top makes it so that when materials, especially heavier materials, slide from a high place onto the conveyor belt 4 through the feed guide plate 5, the materials will generate a large impact force on the conveyor belt 4, and this impact force will be transmitted to multiple supporting rollers 705. The supporting rollers 705 can transmit the impact force to the mounting seat 704, and the mounting seat 704 can cooperate with two sets of spring leaves 703, multiple damping telescopic rods 702 and the base 701 to effectively buffer and shock-absorb the impact force, so that the conveyor belt 4 is not prone to sudden increase in tension, effectively avoiding the situation where the conveyor belt 4 is broken and damaged due to the large impact force, greatly extending the conveying life of the conveyor belt 4, and the supporting rollers 705 will rotate with the movement of the conveyor belt 4, and will not cause movement obstruction to the conveyor belt 4.

[0027] The bottom of the base 701 is fixedly connected to the base 1 , the mounting seat 704 passes through the interior of the conveyor belt 4 , and the top of the supporting roller 705 contacts the top of the inner ring of the conveyor belt 4 .

[0028] The cleaning and dust removal structure 8 includes a mounting frame 801, a cleaning roller 802 and a second motor 803. The mounting frame 801 is in an inverted U shape. The cleaning roller 802 is rotatably mounted inside the mounting frame 801. A brush portion is provided on the outer circumference of the cleaning roller 802. The second motor 803 is fixedly mounted on one side of the mounting frame 801. The output end of the second motor 803 is connected to the shaft end of the cleaning roller 802, so that when the material is conveyed, the cleaning roller 802 can be driven to rotate by the work of the second motor 803. When the cleaning roller 802 rotates, it can cooperate with the brush portion provided on the outer circumference to continuously clean the surface of the conveyor belt 4, maintain the cleanliness of the surface of the conveyor belt 4, so that it will not affect the normal conveying of the material, and does not require manual cleaning, which saves time and effort and is highly efficient.

When the cleaning roller 802 rotates, it can cooperate with the brush part set on the outer side of its circumference to continuously clean the surface of the conveyor belt 4, maintain the cleanliness of the surface of the conveyor belt 4, so that it will not affect the normal transportation of materials. There is no need for manual cleaning, which saves time and effort and is highly efficient. When the cleaning roller 802 rotates to clean the surface of the conveyor belt 4, the exhaust fan 804 can work in conjunction with the dust box 805 and the two ducts 807 to generate suction at the two dust hoods 808, and the smaller debris and dust generated by cleaning can be sucked into the dust box 805, and the filter plate 806 intercepts and filters it and leaves it in the dust box 805, so as to achieve the purpose of dust collection and prevent a large amount of smaller debris and dust from floating into the nearby air and endangering nearby workers.
