Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a conveyor bottom plate cleaning device. Background Technology

[0002] In modern industry, the scale of raw material transportation operations in sectors such as metallurgy, building materials, and ports is constantly expanding, placing higher demands on the continuity and efficiency of material transportation. Belt conveyors, with their significant advantages of strong conveying capacity, stable operation, and low energy consumption, have become core equipment for undertaking the continuous transportation of bulk materials. During operation, due to the impact of materials falling from the conveyor belt and the vibration of the belt itself, a small amount of debris inevitably falls from the conveyor belt. To prevent this debris from scattering in the working environment, contaminating surrounding equipment, and affecting normal equipment operation, and to prevent material from splashing everywhere and causing environmental pollution and mess, a non-working surface (base plate) is installed under the belt conveyor specifically to catch the falling debris.

[0003] However, under actual operating conditions, the non-working surface (base plate) of belt conveyors faces complex and severe material adhesion problems due to the influence of ambient temperature and humidity, conveyor belt vibration, and the characteristics of the materials themselves, especially when transferring sticky or fine-particle materials. Currently, the cleaning of residues on the non-working surface (base plate) is generally done manually, and its cleaning efficiency is highly dependent on the operator's skill level and experience, resulting in significant differences in cleaning effectiveness among different personnel. Furthermore, since belt conveyor systems often require continuous operation, manual cleaning cannot be carried out simultaneously with equipment operation, leading to the accumulation of residues that cannot be removed in a timely manner. This not only increases the difficulty of subsequent cleaning but may also affect the normal operation of the belt conveyor due to excessive residue. More seriously, during manual cleaning, workers need to be in close contact with operating machinery, facing the risk of mechanical injuries such as being caught in or colliding with moving parts; and when cleaning dusty materials, they are highly susceptible to inhaling large amounts of dust, leading to occupational health problems such as pneumoconiosis. This not only seriously threatens the life and health safety of workers but also significantly increases their labor intensity. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a conveyor bottom plate cleaning device that can solve the technical problems of inconsistent results in manual cleaning of conveyor bottom plates, the inability of manual cleaning to be carried out simultaneously during equipment operation, and the risk of mechanical injury and occupational health risks to cleaning personnel who are close to the equipment and who inhale dust at close range.

The end of the tensioning shaft I204 passes through the end of the tensioning main component 201 away from the front support leg 101, and the belt 8 passes over the surface of the tensioning shaft I204.

[0035] In the embodiments described in this utility model, the reel assembly I3 has the function of being wound together by the first end of the belt 8. The reel assembly I3 is located below the tensioning assembly I2.

The end of the reel I302 passes through the end of the main reel component away from the front support leg 101, and the first end of the belt 8 is wound around the surface of the reel I302. When the conveyor bottom plate 1 cleaning device is in standby mode, most of the belt 8 is wound around the surface of the reel I302. When it is necessary to start the process of cleaning the material adhering to the surface of the belt 8, the upper motor 303 connected to the reel I302 will rotate in the opposite direction so as to unwind the belt 8 wound around the surface of the reel I302.

[0036] In the embodiments described in this utility model, the support foot includes a left support foot and a right support foot symmetrically arranged therewith. The motor bracket is located at the outer end of the left support foot and is used to provide support for the lower motor 702. The vertical support plate 5 includes a support plate I and a support plate II symmetrically arranged. The support plate I and the support plate II are respectively fixedly connected to the top ends of the left support foot and the right support foot. The tensioning component II 6 and the cleaning component 9 are both located between the support plate I and the support plate II. The left and right ends of the tensioning component II 6 and the cleaning component 9 are respectively connected to the support plate I and the support plate II through bearing seats.

[0037] In the embodiments described in this utility model, the tensioning component II6 serves to tension the tail end of the belt 8 covering the surface of the base plate 1. Through cooperation with the tensioning component I2, it can tension the belt 8 covering the surface of the base plate 1. The tensioning shaft II601 is located at the tail end of the base plate 1. The end of the tensioning shaft II601 penetrates the surface of the vertical support plate 5 and is connected to the vertical support plate 5 through a bearing seat. The belt 8 wraps around the surface of the tensioning shaft II601. The winding assembly II7 serves to wind the belt 8 together from its tail end.

The end of the roller II 701 passes through the inner end face of the support foot and is connected to the inner end face of the support foot through the bearing seat. The tail end of the belt 8 is wound around the surface of the roller II 701. When it is necessary to start the process of cleaning the material adhering to the surface of the belt 8, while the upper motor 303 drives the roller I 302 to rotate in the direction, the lower motor 702 connected to the roller II 701 is activated and drives the roller II 701 to rotate in the forward direction, so that the belt 8 runs downward along the inclined direction of the base plate 1 and gradually winds around the surface of the roller II 701. During this period, the cleaning mechanism cleans the material adhering to the surface of the belt 8.

[0038] In the embodiments described in this utility model, materials can be conveyed via the surface of the belt 8. During the material conveying process, the cleaning device of the conveyor base plate 1 is in standby mode. At this time, most of the belt 8 is wound around the surface of the reel I 302. The cleaning component 9 has the function of cleaning the material adhering to the surface of the belt 8. The cleaning component 9 is located obliquely above the tensioning component II 6 and in contact with the upper surface of the belt 8. The end of the cleaning roller 901 penetrates the surface of the vertical support plate 5 and is connected to the vertical support plate 5 through a bearing seat. The surface of the cleaning roller 901... The belt 8 is equipped with wear-resistant bristles that contact the upper surface of the belt. Under the action of the sweeping motor 902 connected to the sweeping roller 901, the belt 8 rotates during operation to peel off the material adhering to its surface. The collection bin 10 is located directly below the contact point between the wear-resistant bristles of the sweeping roller 901 and the belt 8. It has the function of collecting the adhering material peeled off from the surface of the belt 8 by the wear-resistant bristles of the sweeping roller 901. The upper part of the collection bin 10 is shaped like a bucket to facilitate the centralized collection of the material adhering to the belt that falls into the collection bin 10.

[0039] In the above embodiments of this utility model, the surface of the sweeping roller 901 can also be configured as a uniformly arranged wear-resistant scraper, so that it can rotate under the drive of the sweeping motor 902 and peel off the material adhering to the surface of the belt 8 when the belt 8 is running, so that the adhering material falls into the collection bin 10.

[0040] In the embodiments described in this utility model, the conveyor bottom plate 1 cleaning device further includes an electrical control mechanism. This mechanism controls the movement of the belt 8 and the cleaning roller 901. The electrical control mechanism includes a microcontroller and sensors. The microcontroller calculates the rotation angle and stroke of the motor based on information transmitted from the sensors. The microcontroller is communicatively connected to the sensors. The microcontroller can be a Siemens S7-1200 PLC controller.

[0041] It should be noted that this application does not improve the programmable program of the Siemens S7-1200 PLC controller, but only utilizes its existing control program and principles to realize the functions of data calculation and information transmission and reception; for the control program and principles involved, please refer to the product manual or existing technical documents of the controller.

[0042] The sensors are located at the upper motor 303, the lower motor 702 and the cleaning motor 902, respectively. The sensors are incremental rotary encoders, which can detect the incremental rotation of the motor to provide feedback on the angle change, and transmit this information to the microcontroller to calculate the rotation angle and stroke of the motor.

[0043] Based on the above, the working steps of this utility model are as follows:

[0044] Step S1: When the cleaning device of the conveyor bottom plate 1 is in standby mode, the upper motor 303, the lower motor 702 and the cleaning motor 902 are all in a non-started state. Most of the belt 8 is wound around the surface of the roller I 302, and the tension bracket I has been adjusted and fixed to a suitable position by the adjustment hole 203, so that the belt 8 that passes around the tension component I 2 and tension component II 6 and is wound around the surface of the roller component I 3 and roller component II 7 is taut and covers the surface of the bottom plate 1. At this time, material can be conveyed through the surface of the belt 8.

[0045] Step S2: When the material conveying process ends and the process of cleaning the material adhering to the surface of the belt 8 is started, the cleaning motor 902 is energized and drives the cleaning roller 901 to rotate. Subsequently, the upper motor 303 starts and rotates in the opposite direction to unwind the belt 8 that is wound around the surface of the roller I 302. At the same time, the lower motor 702 starts and rotates in the forward direction so that the belt 8 runs downward along the inclined direction of the base plate 1 and gradually winds around the surface of the roller II 701. At this time, under the action of the cleaning motor 902 driving the cleaning roller 901 to rotate, the loose material falling off the surface of the belt 8 will fall into the collection bin 10 when passing the contact position between the belt 8 and the tensioning component II 6. At the same time, the material adhering to the surface of the belt 8 is peeled off by the wear-resistant bristles of the cleaning roller 901 that is in contact with the surface of the belt 8 and swept into the collection bin 10.

[0046] Step S3: In step S2, most of the belt 8 is wound onto the surface of the roller II 701 under the drive of the lower motor 702. At this time, the upper motor 303 is controlled to rotate in the forward direction, and the lower motor 702 starts to rotate in the reverse direction, so that the belt 8 runs upward along the inclined direction of the base plate 1 and gradually winds onto the surface of the roller I 302. While the cleaning motor 902 continues to drive the cleaning roller 901 to rotate, the cleaning roller 901 can achieve the purpose of secondary cleaning of the surface of the belt 8 that is in contact with its wear-resistant bristles. When most of the belt 8 is rewound onto the surface of the roller I 302, the process of cleaning the material adhering to the surface of the belt 8 is completed.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
